The invention relates primarily to the field of hydraulic manipulators installed on vehicles, and can be used in other areas of technology where there is a necessity of increasing the stability of the machine using dopolneniya, implemented in the construction of hydraulic cranes, cranes and various types of vehicles, both domestic and foreign developments.From domestic to include the outriggers of the crane ISS-4531 "Balashikha, mobile cranes plant" (journal of Construction and road machines", N 10, 1988, UDC 629.114.4-474.22, page 11, Fig.1, 2).Of the known samples of the supporting devices foreign developments greatest interest for consideration are the outriggers on the application GB, 1577578, B 60 S 9/02, 1980, and US, 4118054, 60 S 9/00 (publ. 1978 October 3, T. 975, N 1 "OFFICIAL GAZETTE") and otherAlmost all of the known outriggers are raised manually or by means of a hydraulic cylinder, legs, ending with the reference heels.In some of them the translation of the extended legs in a transport position shall be implemented by retracting its inside front outrigger without deviation from the vertical. Support foot are down (see, for example, GB, 2058693 A UK, MCI B 60 S 9/00, publ. 1981, April 15).However, despite the relative simplicity of this decision it has obvious drawbacks, due to the low location of the outrigger in tradesecret areas, and especially in the forest, in the presence of various kinds overcome obstacles (stumps, bumps, and other). In the operation of such equipment in off-road conditions in the spring and fall seasons outriggers when driving intensively thrown dirt road.According to another known technical solutions outriggers with drawn inward stand legs by an appropriate rotation about the axis of suspension, in a plane parallel to the longitudinal axis of the machine deviates from the vertical at an angle of about 30-90owith the lock in this position.But in this case they are in the lower part of the machine and for this reason they possess the same disadvantages as discussed above analogues.In some cases, the translation of the outriggers from the extreme lower (working) position to transport position, with the laying inside the base of the manipulator (the machine) is carried out by means of specially provided for this purpose mechanisms, lever, or other type actuated from a self-contained hydraulic cylinders (see, for example, the above GB, 1577578 A1, MKI B 60 S 9/02, publ. 1980 and BS, 4118054 A, B 60 S 9/00, 1978).But such decisions are complex in their design and because of the availability of the management.The most optimal in terms of protection of the outriggers from the dirt and pull them safe when driving zone is circuit-layout solution, implementing the translation of the outrigger from the working position to transport position by turning it relative to the suspension point 180oin the plane perpendicular to the longitudinal axis of the machine, reference fifth up.In this case, the outriggers are raised high above ground and do not interfere with the movement of the machine selenoproteins areas.In the design of hydraulic cranes of a number of domestic and foreign counterparts of the above rotation of the rack with an outrigger cylinder 180ocarried out manually. This makes possible to simplify the design, but significantly affects the working conditions of the operator.Due to the large weight of the outriggers (for hydraulic cranes middle class with lifting moment 65-85 kNm he is about 60-70 kg) perform this operation for one person is often a daunting task.One of the known analogues of the proposed technical solutions closest (prototype) can serve as a reference device of the semi-trailer with side swing outriggers Dr is incorporated swivel is suspended on the frame of the trailer, with the possibility of transfer from the transport position into the working position and Vice versa by an appropriate rotation in the transverse plane, telescopic stand with drawer, equipped with a fifth reference, kinematically connected with the frame provideproperty link spring-type, and a removable pin fixation element of its extreme positions.However, given the nature of the structural design, it has several significant disadvantages.In particular, the envisaged design of the known device layout pivoting outriggers with horizontal arrangement of them in the transport position, it is extremely difficult to implement in installed on production vehicles-hydraulic cranes with issues in the transverse direction outriggers, not going beyond the standard dimensions of these funds. Moreover, with this arrangement, the outriggers are positioned low enough on the level of the side members of the frame of the vehicle, and when the last movement can zabrasyvaetsya road dirt.The design known support device does not allow to realize the rotation of each of the outriggers 180orelative p to the plane of the supporting device.When the hydraulic extension floating sections outriggers spring provideproperty elements, incurring additional stretch, have a significant resistance to their movement. In this context, the hydraulic system of the known device must have high energy characteristics providing overcome it.Translation outriggers known device from operating position to transport position is slow.This disadvantage is due to the fact that in the known device used for this purpose, the force of the springs is spent not only on the performance of work associated with lifting outriggers, but also to overcome the corresponding hydraulic resistance in the displacement of oil from the working cavities of their cylinders through the valve in hydraulic oil tank.In addition to all the above in the design of the known support device does not provide mechanisms to adjust pre-tension springs provideproperty links and lock scattering their parts in case of failure.The present invention is to simplify the design and improved the PTO as a whole.In accordance with the invention this objective is achieved in that in the proposed outrigger spring provideproperty elements placed on the sides of the rack, and the outrigger equipped with screw adjustment mechanisms efforts pre-tension springs connected with catching the ends of the latter, the opposite attachable to the base, and locking mechanisms, scattering parts of the mentioned springs in case of their destruction.While the base has side walls, each of which in the area of the holes used for fixing the rotary rack with retractable claws in its working position, is coaxially fixed towering over them boots, made in the form of restrictive visors C-shaped configuration with rounded edges facing convex surface toward interacting with them during rotation of the rack in the working position of the springs, and in the case retractable legs mounted for adjustment of its spatial position of the double-sided handle.The invention is illustrated in the drawing, which shows:
in Fig. 1 - General view of the proposed outrigger transport position to one of the split timing is;
in Fig. 3 - remote element B, explaining the design become automatically self-centering support feet retractable legs of the outrigger;
in Fig. 4 is a view In side of the outrigger in the area of provideproperty elements;
in Fig. 5 - type G front provideproperty element;
in Fig. 6 is a cross section d-D retractable legs of the outrigger at the location of bilateral handle used to rotate it around the axis of the suspension on the ground;
in Fig. 7 is a cross section e-E design an outrigger at the place of fixation of the rack on the ground in the transport position;
in Fig. 8 - the option to install an outrigger on a sliding beam Foundation.The proposed outrigger contains pivotally suspended by means of axis 1 on the base 2 rack 3 with retractable claw 4 in the form of a hydraulic cylinder double acting, at the end (stock) 5 which is mounted samoustraniajutsia support foot 6, and a removable pin element (bolt) 7 fixing it in the last (transport and working positions) position.Hour 3 and the base 2 is kinematically linked through provideproperty elements.These elements made in the form of two placed on each side of the rack opposite each other in AAMI 10 is connected to the axes 11 and 12, console mounted on the side walls 13 and 14 of the base 2 perpendicular to the plane of rotation of the strut 3.The hooks 15 other ends of the springs 8 and 9 of the articulated rods 16 and 17 of the threaded adjustment mechanisms 18 efforts pre-tension of each of the threaded shanks 19 are freely passed through the holes 20 in the brackets 21 axis 22 that is installed in a through hole 23 of the rack 3, oriented perpendicular to the plane of its rotation.The threaded shank 19 of the rod 16 and 17 cooperate with the tensioning nuts 24. The locking rods 16 and 17 in position is carried out by means of nuts 25.Such fastening of the springs 8 and 9 has a swivel feature. This makes them particularly suitable for joining parts (grounds 2 and 3 hours) in this case, the relative angular position of which is changed when translating an outrigger from the transport position into the working position and Vice versa.Geometrically axes 11 and 12 of the base 2 is shifted upward relative to the point (axis 1) articulated suspension 3 hours. Consequently, the springs 8 and 9 have a minimum length when the outrigger transport (upper) position and a maximum in Raboche rotation of the rack 3 with retractable claws (cylinder) 4 axis 1 hanging it on the base 2, the change in these limits the length of the springs 8 and 9 is accompanied by a proportional change the tension of their efforts.While the moments generated about the axis 1 of rotation of the own weight of the outrigger and the force of the springs 8 and 9 have different orientation (sign) and balance each other. The selection of the required rigidity and fixing points of the springs 8 and 9 on the base 2 and rack 3 can provide a very efficient balancing of the above points (balancing the outrigger relative to the axis of rotation). As a result the amount of work effort required to perform the above operation turns out to be insignificant.In principle, to solve this problem we can use non-metallic provideproperty parts, for example, rubber cords, as well as torsion springs, etc.The proposed outrigger equipped with locking mechanisms 26 of the scattering of parts of the springs 8 and 9 in case of their failure (breakage). These mechanisms are made in the form of missed with the necessary degree of sagging through each spring safety cable 27. The ends 28 and 29 of the safety cables 27 fixed to the axes 11 and 12 of the base and consoles 21 axis 22 hours 3 mechanical privating a removable protective sheath of elastic, for example, canvas or synthetic fabric, coaxially covering the springs on the outer diameter with the required degree of mobility in the axial direction. Possible design protective cover case of the two telescopically jointed, thin-walled metal pipes.For convenience translation of the outriggers from the transport position into the working position and Vice versa in the case of the hydraulic cylinder 4 extension support feet 6 mounted with the possibility of adjusting the spatial position of the two-way knob 31.In the original (transport) position the outriggers raised with reference heels 6 up and fixed by pins 7 in the holes 32 of the base 2. When the rod 5 of the cylinder 4 fully "drowned" (retracted), and the springs 8 and 9 are of minimum length.Translation of an outrigger from the transport position into the working position and Vice versa is carried out as follows.First, by extracting the pin 7 of the holes 32 of the base 2, respexit rack 3. After it is released hour 3 with 4 cylinder extension support feet 6 is balanced about the axis 1 of rotation condition, because the moment due to its weight is balanced by protivodeistvie the e is carried out manually by turning the operator of the rack 3 with the 4 cylinder 180othe bottom axis 1 suspension.When this value is applied accordingly to the handle 31 efforts (dynamic pull) does not exceed 10 - 15 kg In the lowest (operating) position rack 3 fixed pivot 7, the insertion into the holes 33 of the base 2. After fixing the rack 3 in this position the flow of fluid in podporchennuyu cavity 34 4 cylinder push rod 5 to meetings support feet 6 with the ground, providing power to "unload" springs the chassis of the vehicle and increase stability during loading and unloading.Upon completion of these works by means of a flow of the working fluid in the rod cavity 35 of the hydraulic cylinder 4, the piston rod 5 to be drawn into its housing until it stops. Then, remove the bolt 7 from the holes 33 of the base 2, again respexit rack 3 outrigger and manually by turning 180oupwards about the axis 1 suspension, transfer it from working position to transport position (at the top).In the transport position, the outrigger fixed pivot 7, the insertion into the holes 32 of the base 2.In this position, the outrigger is located fifth reference 6 up in a safe and the most favorable conditions for the conduct of the king pin 7 of the holes 32 and 33 of the base 2 is provided with a spring-loaded latch 36.In some cases, because of the nature of the structural design of the Foundation 2 and 3 hours, and the actual location of the points of fastening them to the ends of the springs 8 and 9 of the latter when the outrigger is in operating (lowest) position can block the holes 33 of the base 2, thus preventing the possibility of loading the bolt 7 of the fixing stand.To exclude the specified circumstances on each of the side walls 13 and 14 of the base 2 in the area of the holes 33 is coaxially fixed towering over them rumble strips 37 and 38. These bump stops are made in the form of restrictive visors C-shaped configuration with rounded contours. The convex part of the rumble strips is oriented towards applied to them when translating an outrigger in the working position of the springs 8 and 9. When the rotation of the outrigger in the operating position of the spring 8 and 9 of its lateral surface abuts the baffles 37 and 38, preventing the overlapping of the holes 33 tel springs.Met with strikers middle part of the spring, slightly deformed, gently squish around them and deviate away from the hole 33 without interfering with the installation of pin 7 of the fixing rack 3.Where can constructively avoi is toiki 3 with retractable claws 4) in the working position, the baffles 37 and 38 on the side walls of the base is not set.Declare the outriggers without any restrictions can be set on the basis of hydraulic cranes without adjustment, and the adjustment of their departure. In the first case, the distance between outriggers constantly, and the second may change if nominated from the Foundation of the special beams 39.For lifting and lowering the outriggers of the proposed design does not require stand-alone hydraulic actuator and associated control channels. They are not complicated in design, convenient and safe in operation. To service a single operator. In this case, the amount required to translate an outrigger from one position to another effort does not exceed permissible relevant regulations of values.Design features of the proposed outriggers allow you to implement the minimum possible time of their transfer from the transport position into the working position and Vice versa due to the significant limitation of the number required for this job transitions (operations).In the design of the proposed outrigger are widely used in machines repeatedly reproduced from developed her documentation in terms of production on conventional machine-building plants.This solution is implemented in prototypes of an improved design of hydraulic crane series Sinemorets-75" development of JSC "NC Uralterminalmash" installed on the chassis of automotive vehicles.These samples have been successfully pilot-tested. The tests confirmed the high efficiency inherent in the design of the proposed outrigger technical solutions.Obtained during tests of the proposed outrigger data confirm the possibility of obtaining by carrying out the invention the above-mentioned technical effect consists in the improved performance of the proposed outriggers, and therefore equip their hydraulic cranes with vehicles in General. 1.
