Abstract
The utility model relates to a support oil cylinder turnover mechanism of a lorry-mounted crane, belonging to the support oil cylinder turnover mechanism of hoisting machinery. One end of a support oil cylinder piston rod of the support oil cylinder turnover mechanism is connected with a movable leg by a hinged shaft II, and the other end thereof is connected with a turnover sliding bar seat by a hinged shaft I; the support oil cylinder piston rod is parallel to the turnover sliding bar seat which is internally provided with a turnover sliding bar that is connected with a turnover sliding bar cam block; and the turnover sliding bar cam block is connected with one end of a short connecting rod by a hinged shaft III, the other end of the short connecting rod is connected with the movable leg by a hinged shaft IV, and the movable leg is also provided with a hinged shaft V. The mechanism has the advantages that the support oil cylinder turnover mechanism is suitable for automobile chassis matched with special type machines such the lorry-mounted crane and the like, and is beneficial to restructuring the chassis; and when in a driving state, a support oil cylinder is turned over above a mounting surface of the lorry-mounted crane, so that the mechanism has compact structure, can adapt to most automobile chassis and greatly improves the passing ability of the whole automobile.
Description
Technical field
The utility model relates to a kind of support oil cylinder automatic turning mechanism of support oil cylinder switching mechanism, particularly a kind of lorry-mounted crane of elevator machinery.
Background technology
Lorry-mounted crane and other multiple elevator machinery all are equipped with the vertical leg oil cylinder.The main effect of vertical leg oil cylinder is by increasing the support interval of hoisting crane support, improving the stability and the hoisting capacity of hoisting crane.In order to compensate ground-surface inclination in operation place and injustice, strengthen the stability against overturning of hoisting crane, every supporting leg also should be able to be regulated length and height separately.Supporting leg is overhanging landing when operation, and the hoisting crane lifting is liftoff; When travelling, supporting leg is regained, so both dwindled the oad of car load, improved the crossing ability of elevator machinery again.
At present, on the elevator machinery there be common supporting leg pattern: breast-stroke, H type, X type, radiant type, several supporting legs of radial type.Lorry-mounted crane generally adopts H type supporting leg form, but this kind supporting leg is not fine for the chassis comformability of two propons, all will solve by the upset of support oil cylinder and the second bridge wheel interference problem usually.
And lorry-mounted crane generally adopted H type supporting leg form in the past; be same as Convenient table and adopt the two-chamber form; the both sides support oil cylinder has the longitudinal separation difference not in same plane; wherein a side leg oil cylinder is interfered with two propons car chassis second bridge wheels through regular meeting; and the leg disc ground Clearance of support oil cylinder is less; the motoring condition crossing ability is poor
The utility model content
The purpose of this utility model is to provide a kind of: to the support oil cylinder automatic turning mechanism of the good lorry-mounted crane of the chassis comformability of two propons.
The purpose of this utility model is achieved in that this supporting leg switching mechanism includes the support oil cylinder piston rod, hinge, upset slip pole socket, the support oil cylinder cylinder barrel, hinge II, the upset sliding bar, upset sliding bar cam bit, hinge III, short connecting rod, hinge IV, hinge V and movable leg, one end of support oil cylinder piston rod is connected with movable leg by hinge II, the other end is connected with upset slip pole socket by hinge I, the support oil cylinder piston rod is parallel with upset slip pole socket, in upset slip pole socket, the upset sliding bar is arranged, the upset sliding bar is connected with upset sliding bar cam bit, upset sliding bar cam bit is connected with an end of short connecting rod by hinge III, the other end of short connecting rod is connected with movable leg by hinge IV, also has hinge V on movable leg.
Beneficial effect: owing to adopted such scheme, lorry-mounted crane is under the cruising state, support oil cylinder turn to position vertically upward, be that the following lorry-mounted crane of automotive frame attachment face has only a spot of parts to expose, this makes lorry-mounted crane that good comformability be arranged when the two propons car chassis of coupling, avoided two propons car chassis second bridge wheels, and the ground Clearance of having improved lorry-mounted crane.Chassis comformability to two propons is good, has reached the purpose of this utility model.
Advantage: the support oil cylinder switching mechanism is suitable for special mechanical coupling car chassiss such as lorry-mounted crane, helps the chassis transformation of the way.Support oil cylinder turns over to more than the lorry-mounted crane attachment face under the driving states, and compact conformation can adapt to most of car chassis, improves the car load crossing ability simultaneously greatly.

Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is a working state figure of the present utility model.
1, support oil cylinder piston rod; 2, hinge I; 3, upset slip pole socket, 4, support oil cylinder cylinder barrel; 5, hinge II; 6, upset sliding bar; 7, upset sliding bar cam bit; 8, hinge III; 9, short connecting rod; 10, hinge IV; 11, hinge V; 12, movable leg.
The specific embodiment
Embodiment 1: this supporting leg switching mechanism includes support oil cylinder piston rod 1, hinge I 2, upset slip pole socket 3, support oil cylinder cylinder barrel 4, hinge II 5, upset sliding bar 6, upset sliding bar cam bit 7, hinge III 8, short connecting rod 9, hinge IV 10, hinge V 11, movable leg 12, one end of support oil cylinder piston rod 1 is connected with movable leg 12 by hinge II 5, the other end is connected with upset slip pole socket 3 by hinge I 2, support oil cylinder piston rod 1 is parallel with upset slip pole socket 3, in upset slip pole socket, upset sliding bar 6 is arranged, upset sliding bar 6 is connected with upset sliding bar cam bit 7, upset sliding bar cam bit 7 is connected with an end of short connecting rod 9 by hinge III 8, the other end of short connecting rod 9 is connected with movable leg 12 by hinge IV 10, also has hinge V11 on movable leg 12.
When support oil cylinder overturns downwards, support oil cylinder piston rod 1 is overhanging, utilize the support oil cylinder deadweight to make support oil cylinder cylinder barrel 4 around hinge V 11 rotations, oil cylinder connects with upset slip pole socket 3 by hinge I 2, drives upset slip pole socket 3, upset sliding bar cam bit 7 and short connecting rod 9 around hinge IV 10 rotations.In the support oil cylinder rotation process, upset sliding bar cam bit 7 is around hinge III 8 rotations, and when upset sliding bar cam bit 7 broke away from hinge IV 10, support oil cylinder piston rod 1 drove upset sliding bar 6 and slides in upset slip pole socket 3.Behind support oil cylinder Rotate 180 degree, utilize hinge II5 that support oil cylinder and movable leg 12 is fixing.
Support oil cylinder is the anti-motion of downward switching process when upwards overturning.
The support oil cylinder automatic turning mechanism is highly suitable for installing two propons chassis, and the interference problem of the supporting leg and the second bridge wheel can be solved naturally.
