The invention relates to mechanical engineering, in particular to the safety devices designed to hold the rail vehicle from tipping over.

Known anti-theft rail grip (AU No. 1221187, B66C 9/18), containing two shoulders pinned levers on the end of a short lower arm of each of which has a groove into which is inserted to move the presser podrugina sponge with a notch, and the end of the long upper arm is kinematically connected with a drive rotation of levers, one side of the presser sponge is made with symmetrical longitudinal grooves for engagement with the springs, but the opposite L-shaped in plan surface mating with the inner surface of the groove.

The disadvantages of this device are:

1. The complexity of the design.

2. The clip is only the side faces of the rail, which reduces the reliability at the tipping point.

The closest analogue of the claimed device is a device to prevent tipping of the mobile crane (AU No. 1294759, B66C 23/88)containing fixed on the base frame of the crane remote lever with the driving element mounted for movement along the rail, located along the path of movement of the crane, remote lever hinged to the base frame, napravlyayus is made with limiters angular movements of the driving element in a vertical plane, and the device is provided with a hinge mounted on the base frame optional remote lever at the free end which is an additional driving element can be moved by an additional guide, hydraulic power cylinders, the piston rod of the first of which is connected pivotally with additional external lever and spring-loaded with respect to it, and the rod of the second main lever, the torque of the hydraulic cylinder through the valve, the movable element of which is pivotally connected with an additional remote lever and connected with a controlled input of an adjustable throttle through which communicated between a cavity of the second cylinder. The guide is made in the form of a channel, one of the shelves which is an additional guide. Guide installed at anchor.

The disadvantages of this device:

1. The complexity of the design.

2. Requires additional bulky and expensive equipment.

3. The complexity of the installation and configuration of the equipment.

4. Low reliability due to the inertia of the device.

The task of the invention is to increase reliability while simplifying the structure.

The problem is solved due to the fact that the device for preventing tipping of the rail vehicle containing fixed on the base frame remote growling is, driving element mounted for movement along the path of movement of the crane, with the extension arm has a hole in which is installed with the possibility of moving guides rigidly mounted on the continuation of the axis tick capture with self-locking levers, with installed between the guide spring resting with their ends on the remote lever and the axis tick capture and opposite spring rigidly attached to the continuation of the axis tick capture driving element, and the lower levers tick capture made in the form of a broken line with an angle α between them, while the surface of the sponges with notches rigidly attached to the lower ends of the levers tick capture are parallel to the upper shoulders of the rail.

Significant new features:

1. The extension arm has a hole in which is installed with the possibility of travel guides.

2. Guides rigidly mounted on the continuation of the axis tick capture with self-locking levers.

3. Between the rails installed spring resting with their ends on the remote lever and the axis tick capture.

4. On the contrary continue axis tick capture fixed chassis element.

5. The lower arms of tick capture made in the form of a broken line with an angle α between them.

6. The surface of the sponges with notches is estco attached to the ends of the lower levers tick capture, parallel to the upper shoulders of the rail.

These new significant features in conjunction with the known necessary and sufficient to achieve a technical result, in all cases to which the requested amount of legal protection.

The technical result is the reliability of the device due to the rapid operation of the device with the disengagement of the wheels of the rail vehicle and secure fit due to the fact that the spring allows you to keep a running element on the surface of the rail at the beginning of tipping. The mutual position of the parts immediately trigger tick capture, and the installation surface of the jaws with notches shoulders parallel to the top rail allows you to secure the movable means relative to the rail and to prevent tipping. Then tick capture returns to its original position. The simple design also increases the reliability of the device. The device does not require bulky and expensive equipment (channel, anchors, hydraulic equipment), the complexity of the installation and configuration of the equipment.

Figure 1 is schematically shows a device for preventing tipping of the rail vehicle. Figure 2 schematically shows a cross section along a-a, turned.

Device for preventing the disgust of the tilting rail vehicle includes a support frame 1, on which is rigidly mounted remote lever 2. Driving element consisting of a pin wheel 3 mounted on the rack 4, which is rigidly fixed to the continuation of the axis 5 of tick grip 6. Continue to the axis 5 of tick grip 6 is rigidly fixed to the two guides 7 can be moved through the openings 8 of the extension arm 2. Between the guide 7 installed spring 9, with their ends resting on the extension arm 2 and the axis 5 of tick grip 6. Contact wheel 3 with its surface rests on the rail 10. When this tick capture 6 consists of two rods 11 and the bottom two levers 12, made in the form of a broken line with an angle α between this broken line.

Thus, surfaces of the jaws with notches 13, rigidly attached to the lower ends of the levers 12 tick capture 6 are parallel to the upper shoulders 14 of the rail 10.

The device operates as follows.

In the initial position, the distance between the extension arm 2 and the continuation of the axis 5 of tick grip 6 is installed due to selection of the length of the rod 11 so that the surface of the jaws 13 with notch fixed on the lower arm 12 of tick capture 6, does not touch the top of the shoulders 14 of the rail 10. The spring 9 presses on the axis 5 of tick capture 6, thereby pressing the contact wheel 3 through a rack 4 to the surface of the rail 10.

In the case of the beginning of the La overturning the vehicle remote lever 2, rigidly fixed on the frame 1, is moved in a vertical plane above the surface of the rail 10 and continue axis 5 tick grip 6. Due to the force of the spring 9 guides 7 are moved in the holes 8 of the extension arm 2, thus the contact wheel 3 with a rack 4 remains in contact with the surface of the rail 10, and the axis 5 of tick capture 6 remains stationary relative to the surface of the rail 10. Because external lever 2 is moved upward thrust 11 compress the upper part of the tick's grip 6, and the lower portion of tick capture 6 sponges with notches 13 grasps the rail 10, thereby prevent tipping, because sponge with notches 13 are installed parallel to the upper shoulders 14 of the rail 10. Therefore, sponge with notches 13 communicate its surface with the top of the shoulders 14 of the rail 10, creating a secure fit.

When returning rolling means to the initial position of tick capture 6 unlocks the rail 10 by eliminating the interaction surfaces of the jaws 13 with the top of the shoulders 14 of the rail 10, as external lever 2 is returned to its original position and pushes the thrust 11. On the device it is possible to install sound and light alarm about the beginning of the overturning (moment of separation of the wheels of the rail vehicle from the surface of the rail).

Because pre-neizvesten is, in what direction will occur rollover, to prevent it you need to install the second is the same device across diagonally (in plan) of the vehicle relative to the first device.

Device to prevent tipping of the rail vehicle containing fixed on the base frame remote lever driving element mounted for movement along the path of movement of the crane, wherein the extension arm has a hole in which is installed with the possibility of moving guides rigidly mounted on the continuation of the axis tick capture with self-locking levers, with installed between the guide spring resting with their ends on the remote lever and the axis tick capture, while the opposite spring rigidly attached to the continuation of the axis tick capture driving element, and the lower levers tick capture made in the form of a broken line with an angle between them, while the surface of the sponges with notches rigidly mounted on the lower ends of the levers tick capture, parallel to the upper shoulders of the rail.
