Abstract
A telescopic caterpillar advancing means of caterpillar crane is provided, wherein one end of a telescopic oily cylinder is fixed on the base of the crane, and the other end is fixed on the caterpillar rack. The base is connected with the left and right caterpillar rack though the vertical beam fixed on the base, and a fixed pin shaft is arranged between the caterpillar rack and the connecting rod of the base. A prolonged beam is assembled on a horizontal beam on the base through the shaft; a fixed pin shaft is also fixed between the prolonged beam and the caterpillar rack. When the hoisting is processed, the oil cylinder is extended to increase the width of the caterpillar advancing means, and the stability and security of processing can be greatly improved; while running, the oil cylinder is contracted to reduce the width of the caterpillar advancing means. The utility model is convenient for the operating the prolonged beam and reduces the labor intensity of operating stuffs.
Description
Technical field
The utility model relates to the crawler crane technology, particularly utilizes hydraulic efficiency gear to regulate the track unit of width.
Background technology
Crawler crane is one of important branch of crane, and the effect of track unit in the crawler crane complete machine mainly contains: first driving functions, it two is supporting complete machine and a lift heavy thing weight.Under the lift heavy state, more stable in order to make hoisting crane, the width that need increase, base lengthening beam are exactly design-calculated crawler crane parts in order to satisfy this function.
The lengthening beam of prior art is that no hydraulic ram is power-assisted, when the lift heavy operating mode, needs to rotate lengthening beam and becomes same direction with base beam, and the expansion track frame increases the track unit width.Under motoring condition, shrink track frame, promptly rotate lengthening beam and become 90 degree with base beam.Original lengthening beam is made up of joint, backing plate, axle sleeve, side plate, header board, connecting panel, upper and lower plates etc., and the beam body is fixed on the base by axle, and operation labour intensity is big.
Summary of the invention
In order to overcome original lengthening beam the problem inconvenient, that labour intensity is big is installed, takes into account outward appearance simultaneously and technology is easy to make, and reduce manufacturing cost as far as possible.The purpose of this utility model is to provide a kind of flexible track unit of the power-assisted crawler crane of oil cylinder that has.
Track unit is to have base and left and right sides track frame, and wherein base plays supporting complete machine and the effect of lift heavy thing, and base is connected with left and right sides track frame by its crossbeam, and lengthening beam plays the effect of lengthening base crossbeam length.
The utility model is finished by the following technical programs: the flexible lengthening beam device of crawler crane comprises lengthening beam, set pin, connecting rod, telescopic oil cylinder.Oil cylinder one end is fixed on the base, and an end connects track frame.Base is connected with left and right sides track frame by its crossbeam, disposes fixed pin shaft between track frame and base connecting rod.Lengthening beam is fitted on the base crossbeam by its rotating shaft, also is equipped with set pin between lengthening beam and the track frame.When carrying out the lift heavy operation, telescopic oil cylinder is stretched out, and increases the width of track unit, the stability when increasing operation.When needs travelled, telescopic oil cylinder shrank, and reduced the width of track unit.
Effect of the present utility model have following some:
1, makes things convenient for the operation of crawler crane lengthening beam device, alleviated labor intensity of operating staff.
Width when 2, having increased the operation of crawler crane track unit lift heavy, thus significantly improved the job stabilization and the safety of crawler crane.
Description of drawings

Fig. 7 is the scheme drawing of telescopic oil cylinder in the utility model.
Fig. 8 is the scheme drawing of bearing pin 401 in the utility model.There is shown its hook 4011, the latch 4013 of shank 4012 and configuration.
The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described further.
See also Fig. 4 to Fig. 8, the flexible track unit of the utility model comprises lengthening beam 4, bearing pin, connecting rod 6 and telescopic oil cylinder 7.Telescopic oil cylinder 7 one ends are fixed on the hoisting crane base 3, and the other end connects track frame 7.Base 3 is connected with left and right sides track frame 7 by its crossbeam 2.6 on track frame 7 and base connecting rod dispose fixed pin shaft 601.Lengthening beam 4 is fitted on the base crossbeam 2 by its rotating shaft.Also be equipped with fixed pin shaft 401 between lengthening beam 4 and the track frame 7.
When the utility model carried out the lift heavy operation, telescopic oil cylinder was stretched out, and increased the width of track unit, the stability when increasing operation.When needs travelled, telescopic oil cylinder shrank, and reduced the width of track unit.
Concrete operations are as follows:
1, crawler belt is stretched out operation;
1) fixed pin shaft 401 of transfering to lengthening beam and track frame fixed connection to use, and with lengthening beam 4 half-twists, promptly with 7 one-tenth upright positions of track frame;
2) fixed pin shaft 601 on dial-out track frame and the base pipe link, to pressing down, left track frame 7 stretches out with left telescopic oil cylinder 5 joysticks.To pressing down, the right side track frame stretches out with right telescopic oil cylinder joystick;
3) again with set pin fixedly track frame and base connecting rod;
2, crawler belt shrinkage operation
1) extracts fixed pin shaft on track frame 7 and the base connecting rod 6;
2) operate according to the hydraulic control lever label indication of getting off, left telescopic oil cylinder 5 joysticks are upwards lifted, 7 withdrawals of left track frame.Right telescopic oil cylinder joystick is upwards lifted the withdrawal of right side track frame;
3) after long beam folds 90 °, install fixed pin shaft 401.
The utility model is tried out on the SCC800 crawler crane, and trial effect is good.
