Abstract
The utility model relates to a crane mounted on a transport vehicle with a square cabin, which comprises a hydraulic oil tank, wherein the lower part of a beam of the hydraulic oil tank is fixed on a crossbeam between an operator cabin of a transport vehicle and a square cabin, and a force fetching mechanism is directly connected with a vehicle gearbox; both sides of the lower part of the beam are provided with a plurality of hydraulic legs which are used for load bearing during lifting. The beam is connected with a rotating support table, and the lower part of the rotating support table is connected with a control valve set and a rotating gearbox; the lower part of an upright column is hinged with an oil cylinder with amplitude of variation, and a hoisting mechanism is connected with the upright column. One end of each of suspended arms transversely arranged between the operator cabin and the square cabin is respectively hinged with the upright column and the oil cylinder with amplitude of variation, and the other end is connected with a hanging hook set by a steel cable. The rotating center of the crane mounted on a transport vehicle offsets, and the suspended arms are arranged transversely between the operator cabin and the square cabin within a range of width of the transport vehicle. The utility model has the advantages of compact structure, large rotating angle, hydraulic drive for the whole machine and convenient operation.
Description
The utility model relates to a kind of lorry-mounted crane, particularly center of gyration offset straight-arm elevator hydraulic pressure lorry-mounted crane.
In the prior art, lorry-mounted crane mostly is center of gyration symmetrical expression straight-arm hoisting crane, and arm places directly over the compartment, influences the placement of goods, the transport trolley adapted of uncomfortable crossed belt shelter.
The purpose of this utility model provides a kind of straight-arm elevator hydraulic pressure lorry-mounted crane that is suitable for the shelter transport trolley, present technique is to be power with the automotive engine, drive oil pump control by take-off and finish actions such as the revolution of supporting leg location and arm, luffing, flexible, elevator, compact conformation, the revolution amplitude is big, and is easy to operate.
The purpose of this utility model realizes by following measure, a kind of shelter transport trolley lorry-mounted crane, comprise hydraulic reservoir, many groups bolt of rear end plate of its crossbeam (8) bottom is connected on the crossbeam between transport trolley operator's compartment (1) and the shelter (3), take-off (4) driving coupling is on automobile gearbox (5), there are a plurality of hydraulic rams (7), load-bearing when being used for lifting in the both sides, bottom of crossbeam (8).Crossbeam (8) top connects the revolution brace table (9) as main body, revolution brace table (9) bottom that center of gyration is offset to crossbeam (8) one sides connects control cock group (6) and rotary gear box (10), the control cock group (6) that connects and control each hydraulic circuit is joined with the oil pump of take-off (4), revolution brace table (9) drives the gear of column (12) bottom by the rotary teeth wheels, column (12) lower hinge amplitude oil cylinder (11), hoisting mechanism (2) is connected on the column (12), one end of horizontal arm (13) between operator's compartment (1) and shelter (3) is hinged with column (12) and amplitude oil cylinder (11) respectively, and its other end is by steel rope connecting shackle group (14).
The straight-arm winding type telescopic boom that above-mentioned arm (13) is driven by telescopic oil cylinder for the 2-4 joint.
The degreeof turn scope of above-mentioned arm (13) is less than 215 degree.
Pegging graft by telescopic outrigger frame and crossbeam in above-mentioned hydraulic ram (7) top near revolution brace table (9) one sides, during the locomotive hoisting operation, expansion link is outwards pulled out, and increases resistance to overturning.
The utility model has following characteristics: the center of gyration biasing, and arm is horizontally placed in the automobile width range between operator's compartment and the shelter, compact conformation, degreeof turn is big, and the complete machine full hydraulic drive is easy to operate.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is a connection diagram of the present utility model.
