Abstract
The utility model discloses a pipe suspending machine. One end of a hydraulic luffing oil cylinder (11) is hinged with a right supporting base (23) of a crawler type chassis (1), and the other end is hinged with a suspended arm (4); a fixed pulley block (6) is hinged with a head of the suspended arm (4) by a pin shaft (7), and a fixed pulley (8) is hinged with the head of the suspended arm (4) by a pin shaft (9); a movable balance weight mechanism (2) and a lifting hydraulic winch (14) are arranged on a left supporting base (27) on the crawler type chassis (1); a lifting rope (20) on the lifting hydraulic winch (14) is guided by a left guide pulley (26) and a right guide pulley (22) which are arranged on the crawler type chassis (1) to pass through a machine body from a front cross beam (18) below a floor board (19) to be connected with the fixed pulley (8), the fixed pulley block (7) and the suspended hook fixed pulley block (6). The utility model is a pipe suspending machine with low barycenter of a complete machine, high running stability, big operating space, high lifting height, simple structure and easy producing.
Description
Technical field
The utility model relates to a kind of pipe sling.
Background technology
At present, what the pipe sling that uses in the domestic pipeline construction, chassis all adopted is the caterpillar chassis of mechanical drive or hydromechanical drive, and Turning radius is big and stationarity is poor, do not allow about continuous uninterrupted to turn to, make accuracy control and proofread and correct the machine location difficulty.The luffing of arm adopts steel rope+hydraulic wireline winch or steel rope+mechanical winch structure, steel rope passes the sight line that has influenced the driver from the dead ahead of driver's sight line, for avoiding steel rope and driving engine machine loam cake to interfere the winch position is improved, make machine gravity increase riding stability and reduce.Hoist rope passes through from the middle part of body, makes the place ahead of operator's compartment produce the wide slit of about 300mm, causes that reduce in the driver operation space, appearance is poor.The fixed pulley group that hoists adopts the connection of suspension type and arm, and it is big to take height space, has reduced lifting altitude.
The utility model content
Technical problem to be solved in the utility model provides the pipe sling that a kind of machine gravity is low, riding stability is high, the operational space is big, lifting altitude is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: hydraulic luffing oil cylinder one end and described caterpillar chassis right support abutment are hinged, the other end and arm are hinged, and the fixed pulley group is hinged with bearing pin and arm head, and fixed pulley is hinged with bearing pin and arm head; The moving counterweight mechanism and the hydraulic wireline winch that hoists are installed on the left support abutment of described caterpillar chassis, hoist rope is by being installed in the left leading sheave on the described caterpillar chassis, the guiding of right leading sheave, from the front cross rail of below, floor, pass body, link to each other with fixed pulley, fixed pulley group, suspension hook running block.
As a kind of improvement of the present utility model, described caterpillar chassis adopts the all-hydraulic transmission caterpillar chassis.
The utility model is to existing laying tractor, improve from the design of chassis type selecting, luffing mechanism, the structure design of fixed pulley group and the layout of hoist rope, the utlity model has following advantage: 1, the all-hydraulic transmission caterpillar chassis has pivot stud, the on-load functions such as stepless change that turn to, move forward and backward, can accuracy control and proofread and correct machine location.The repertoire that the degree of automation height is the may command chassis with a bar handle only.2, the original function that has kept the chassis can be realized one-machine-multi-function.3, the luffing function of arm adopts two hydraulic rams to drive and realizes the manufacturing cost that reduced simple in structure.4, hoist rope passes in the middle of underfloor front cross rail, has eliminated the wide slit of 300mm, operator's compartment the place ahead, has increased the driver operation space, makes the complete machine outward appearance neatly succinctly be easier to entire arrangement and appearance and modeling.5, the fixed pulley group that hoists is fixed on the head of arm with bearing pin, has eliminated suspension type fixed pulley group to the taking of height space, and increases lifting altitude.
In sum, the utility model is the pipe sling that a kind of machine gravity is low, riding stability is high, the operational space is big, lifting altitude is high and simple in structure, easily manufactured.
Description of drawings
