The invention relates to a device for planning bulk cargoes for leveling material cones that occur when loading the vehicle, in particular rail cars, bulk cargo.

A device for planning bulk cargo to the Republic of Moldova, containing frame construction with an upper frame connected to the upper frame, the scheduler having a lower frame with layout beam, preferably with a plow and located in the direction of movement of vehicles planning the roller lifting device for movement of the scheduler between the upper and lower end positions (see author's certificate N 479706, class B 65 G 69/16 1972).

The known device is used primarily for bulk cargo transported by rail. This does not exclude, of course, its use for bulk cargo transported in other vehicles, such as trucks and ships.

Levelling material cones primarily serves to prevent excessive dust during transportation of bulk cargo and for security reasons should prevent loading unnecessary bulk cargo and help to exhaust protocollist. The known device for planning bulk cargo consists of upper and lower frame resistant design of steel. Both frames are connected to each other by means of a rectilinear guide, offset from its axis. Veit to receive planning beams and connected planning rollers, with the help of which tamped bulk cargo.

The lower frame scheduler is connected with at least one steel cable with a lifting device is firmly mounted on the upper frame. Lifting device is provided with a step for driving with low speed. For the upper and lower point limit switch is installed, respectively, the limit switch. Controls the lifting device operator from a remote control button. Using this button, and visual inspection, the operator moves the scheduler at the desired height above the car, which should occur in the process of levelling bulk material. If you need the height necessary for leveling, is not found immediately, the operator conducts the scheduler down until is found. This process should be repeated as necessary for each car.

Along with monitoring the planning process, the operator should also be sure to pay attention to different heights cars. If the car next to those, which are planning, higher than the previous one, the operator must lift the scheduler, because otherwise, you receive a serious danger that the on and scheduler.

At the end of the process of levelling the operator returns the scheduler up to its original position.

Obviously, the service is known to the scheduler bulk cargo requires special attention from the operator, and in any case there may be errors.

The objective of the proposed invention is to provide a scheduler bulk cones of the above type which operates largely in the automatic mode and at the same time guaranteeing a high degree of reliability and convenient operation for the operator and, above all, to prevent the collision of the scheduler in the lowered condition with vehicles in the work zone.

This problem is solved in accordance with the invention, the device is equipped with a sounding device associated with the lifting device through the control equipment to prevent the collision of the scheduler with the vehicle with bulk cargo, while probing the device comprises a first probe means mounted on the scheduler, and the second probe means mounted on the upper frame, and a lifting device is designed as a cable pull with the opportunity to work with, p is the help, at least two parallel rotary levers.

Device for planning bulk cargo includes, generally, a loading device by which loading of bulk cargo in the vehicle for transportation. The invention provides that the lifting device is associated with the loading device through the control equipment, and the scheduler is automatically moved to the upper position, when the loading device was not used after a certain period of time. In the same way appropriate communication with the scheduler, the latter also moves automatically to the top, if it was not used after a certain period of time. It is a forced move up ensures that the scheduler is not unnecessarily in the danger zone, so at this time completely eliminates the possibility damage.

The probing device is to ensure that the planner is not concerned, for example, a railroad car, and could not be damaged. The same applies to the device, as it is, according to the invention is contactless. On the basis of the invention planiruet visually and there is no danger of damage or destruction of the scheduler. If, for example, change the height of the next car, the first sensing means registers it in a timely manner, after which the lower frame or the scheduler raise so high until you reach the appropriate height for the next levelling bulk material wagon. Second sensing means registers the conveyor of bulk cargo in the zone scheduler. Thus, there is a forced movement of the scheduler in the upper stationary position and its protection from damage in case of an invasion during the process of levelling the next, as needed larger height of the car in the registration area of the second sensing means. Second sensing means preferably directed downwards.

The presence of the device with taut ropes provides good regulation of the scheduler and, in particular, the instant response of the device at the rapidly approaching Transporter of bulk cargo. It provides protection of cables constantly taut when lowering scheduler, so planning device may accordingly be quickly understood with the aid of lifting devices.

It turned out that paddym, but reliable in operation. In any case, means that they can also be used and other lifting devices. We mean, for example, gear lever mechanism or a pneumatic or hydraulic strut that connect the two frames.

Especially appropriate when the maximum degree of reliability for the scheduler is the presence of a lifting device, at least one high and one low speed lift. High lifting speed is calculated so that the scheduler based on the configuration of the approaching transport of bulk cargo is moving until it touches the bottom of the frame. Thanks to the invention, firstly, a step slow working speed with which the lifting device moves the scheduler at the appropriate height for levelling bulk cargo. High speed is set using the control equipment when the probing device produces a corresponding pulse. In such case, the probing device and equipment management determines the provision of timely overlapping large altitude difference at the operating speed. It is, accordingly, sluchaetsa with operating speed at fast speed, so the scheduler is displayed in a timely manner from the zone of danger. The calculation of the maximum speed depends on the location and range of the sensing devices of the claimed device, and the maximum attainable speed of the motion. The calculation of the fast speed lifting the well-known specialist and can simply be composed according to the formula, and should also be considered known coefficient of reliability.

Finally, there are third sensing means located at some distance from the device to the planning of bulk cargo and preferably also behind him in the loading zone of the track or roadway and registering approaching the conveyor of bulk cargo. This is the third sensing means is used for recognition at an early stage of the approach to the planning of the transport of bulk cargo, do not expect, for example, moving with high speed. In this case, the transport is logged, and the scheduler moves to the upper fixed position.

If the first sensing means are positioned in the direction of and against the movement of vehicles, found that the claimed device for planirano on both sides of the contact.

To ensure maximum reliability for the scheduler in the direction of movement and against movement in each of the probing means is provided by at least two preferably located one above the other sensing element. Due to this, even when the failure of one sensor element is guaranteed that will be implemented eat the tone and register of the approaching transport of bulk cargo. If using sensitive elements arranged one above the other, establish a slight height difference of the two cars, the scheduler can be slightly lifted to overlap the altitude difference. If using sensitive elements arranged one above the other, set large height difference between the cars, which are planning, and the next, with the control equipment receives the corresponding pulse so that the scheduler takes its position at the top by means of a lifting device.

In the constructive design of this inventive concept provides that the means of sensing is performed with an infrared sensitive elements. Such means sensing proved to be particularly aisle planner for a long time is in its upper position, it is possible to maintain it in this position using a locking device. It is preferably a mechanical lock. It should be noted that a deliberate move down the scheduler can occur for various reasons, due to functional errors. They can be avoided due to the mechanical lock.

To ensure rapid planning process further provides for the upper and lower stationary installed emergency limit switches to limit movement of the scheduler and the upper and lower adjustable working limit switches for limiting the movement of the scheduler.

The position of the upper and lower alarm limit switch motionless, while working limit switch is installed with the possibility of rearrangement. These switches serve to further automation of the claimed device. For example, when approaching the transport of bulk cargo, you can determine which high-altitude zone are subject to levelling bulk cones. Using the bottom in the upper working limit switches can then set the appropriate height difference, predstavlyaet maximum movement and can contact limit switches, breaking lifting device after you install it in the appropriate position. The same applies, of course, also to the operating limit switch.

To further automate the claimed device has at least one measuring device associated with a lifting device, in particular calcination for registration elevation of the vehicle with bulk cargo.

Assume that the measuring device associated with the lifting mechanism through the control equipment. Thus, no permanent additional settings lifting device to achieve their desired position. You can also successfully avoid misinterpretation that can occur through the fault of the staff.

If the lock state is recorded using the appropriate devices and is passed on to the control equipment, which lifting device is blocked, the scheduler can corrupt and destroy the locking device, if the operator inadvertently actuates the lifting device when locked the scheduler.

To avoid damage to climb the narrow reaches 110%, the handling device automatically disconnects the mechanism.

To reduce dust during land planning activities in accordance with another advantageous form of execution of the invention mounted on the lower frame scheduler provides adjustable spray irrigation device, so depending on the type of bulk cargo can be served more or less water or not to submit it.

Other features, advantages and objectives of the proposed invention can be seen from the subsequent description of examples of implementation on the basis of the drawing. In this case, all described and/or illustrated in the drawing signs in themselves or in any meaningful combination, constitute the subject of the proposed invention.

The single figure represents schematically a side view of the claimed device for planning the bulk material.

The claimed device for planning bulk material 1 has a framework structure 2 with the upper horizontal frame 3, which has a lifting device 4. On the lower side of the upper frame 3 fortified two parallel roller lever 5 and 6, connected by hinges to the upper frame 3 in the positions indicated by the numerals 7 and 8. Neznayu with the upper frame 3 of the lower frame 12, planning with the plow beam 13 and connected planning rink 14 mounted in the direction of movement F. Swing arms 5 and 6 in this form of execution connected by hinges to the bottom frame 12. With the bottom frame 12 is connected also planning a beam 13, is made in the form of a plow. Finally, planning a skating rink located on the lower frame 12 and rotates.

Lifting device 4 in the present exemplary embodiment is executed in the form of a traction rope 15, which has at least one cable 16 connected to the bottom frame 12, the scheduler 11. As shown by the dotted line above the upper frame 3, it can be shifted upward due to the lengthening of the frame 2. Frame 2 is located above the loading gauge 17 and there are preferably stationary. Through the frame structure 2 is held in the proposed scenario, the transport for transportation of bulk cargo, in the form of railway carriages 18 and 19. The carriages 18 and 19 pulls or appropriate tractor or winch mechanism. The carriages 18 and 19 are received from the loading dock, where they were filled with the corresponding bulk cargo.

To the planning device 1 is contactless probing device having a different sensing means, first sensing means 20, 21 of the probing device. The sensing means 20 is installed on the axis against the driving direction F, while the sensing means 21 is installed on the axis in the direction of motion. Each of these two means 20, 21 has at least one sensitive element, two sensitive element arranged next to each other or two sensitive element, preferably located one above the other, which is not illustrated in detail.

Contactless probing device is provided further with a second sensing means 22, which is placed on the upper frame 3 and is directed down the axis. The attachment point is in the direction of movement in front of the outer connection point on the hinge 8 of the lever 6. Then at some distance in front of the frame structure 2 and it is provided by third sensing means 23, 24 located on the axis in the direction of the side walls of passing cars. As a means of sensing, 20, 21, and sensing means 22, 23, 24 may have, respectively, one or two of the sensing element in order to reduce the possibility of failure of one means of sensing. In the proposed case we are talking about the ultrasonic barrier, the simulation 20-24 associated with cable-pull 15 through the control equipment. Rope pull in the future will be considered in more detail. Cable pull can operate at two speeds. There is, first, a relatively slow operating speed, and secondly, high lifting speed. High lifting speed is calculated based on the measured means of sensing values that are processed by the control equipment, and the scheduler 11, on the basis of the path of the approaching transport of bulk cargo is moving, until it touches the planning beams. Thus, high lifting speed when the speed of the carriages 18, 19 0.4 - 0.5 m/s and the distance between the end wall and the two following each other wagons, equal to 1 m, can be at least 0,255 m/sec, if the cable pull slightly raises the scheduler 510 mm With regard to the appropriate safety speed should be about 0,373 m/s.

Cable rod 15, the capacity of which is about 50 kN, provided with a device for protection against overload or shutdown in case of overload, which disables the traction rope at 110% rated load. The working load of the rope pull is 32 kN, which means 16 kN on one t is the scheduler in position, levelling hangs over the object. Typically, the operator will attempt to "liberate" the scheduler using a cable pull. Therefore, to avoid damage is disabled during overloads.

Along with the ability to turn off in case of overload the cable rod 15 is provided with the device tightly stretched rope or device off with the weakening of the rope with a safety device of the crane (emergency switch). Then it is equipped with a limit switch front with 4 contacts. When it comes to the upper and lower alarm limit switch, and the upper and lower operational limit switch.

The disconnect device with the weakening of the rope, not described in more detail, keeps the cable or cables constantly taut. Upper and lower alarm limit switches set the end position of the scheduler.

The only figure the dashed line denotes the upper position in accordance with the location of the upper emergency limit switch. Between the altitude difference that is installed with the upper and lower alarm limit switches, are upper and lower working limit switches. Field operation 4.2 m, 4,4 m Scheduler 11 then reaches the top of the desktop switch (set point turn) and then the desired height. If planning a beam during a given course should lead to the desired position, a preliminary search of the height of the ends. A preliminary search of the height can be resumed using the switch or emergency switch. Manual control at this time is locked.

Before and after pre-selection of the height manual service is active. The operator, therefore, can carry out a manual control can be installed in any position between the upper and lower working limit switch. Next, the scheduler 11 is connected to the loading device with the above-mentioned control. If the loading device was not used after a certain period of time, the scheduler automatically moves to the top point of working the limit switch and takes a fixed position. The same thing happens if the scheduler has not been used after a certain period of time. When the scheduler 11 is moved upwards to the stop position, the cable pull 15 off using the upper working Praia brakes during long periods of inactivity, provides mechanical lock that can be done either manually or using a suitable locking devices. The lock state is registered by means of a measuring device and is marked on the control unit, for example, using a red light.

To perform planning work must first be released scheduler that is registered by means of a measuring device. The upper working limit switch registers scheduler and after unlocking using the measuring device sends a signal "ready for operation" by remote control, for example, using green light bulbs. The scheduler is fashionable to bring in the desired position by pressing the button. You can reach the respective elevations through a single click of an appropriate height. Check the height is with the use of measuring devices, calcination or similar measuring instruments in accordance with the desired height of the registers corresponding to the position of the scheduler and passed for further management.

If a separate sensing means fail or are not accepted measures of Besoli disable optical and acoustic warning signals.

Then, when the malfunction of the device tightly stretched rope can be interrupted service manual, and preliminary selection of height. After a fault, you either again to pre-select height, or to find the desired point manually. Fault overload circuit breaker after a fault you need to use the activation button. Then, as in the device tightly stretched rope, you need to re-do the selection. If activated one of the emergency switches, manually or using a preset height, corresponding to the direction of carriage movement is blocked. This can only be done with manual control via limit switch. If the loading device is not ready, then it cannot be actuated from the main control panel. By switching the supply line from the main control on the peripheral you can manage the installation in repair mode. Further provided by the overlapping of the work of the limit switches. In this mode the operator, bypassing the working limit switches, can, thus, to verify the emergency limit switches. In case of operation and the creation for the planning of bulk material in the wrong direction, the scheduler translates a forced manner in the upper working position limit switch. The same thing happens in the direction of motion when you do not have any one of four heights. If the planning work is done manually and planning beam is approaching the end of the car less than 1 m, the lever is moved to the upper working limit switch.

In General it can be stated that the proposed invention makes it possible to provide a reliable device for planning the bulk material, and the scheduler is protected from contact with cars. Start installation can be carried out manually, semi-automatic or fully automatic mode. Its application is possible wherever used bulk material.
