Jacking single-lifting device of test motor carrying tool vehicle

[ field of technology ]

The utility model relates to a lifting single-lifting device of a test motor carrying tool vehicle, and belongs to the technical field of test motor lifting.

[ background Art ]

Before the performance test of the motor, the large motor is positioned on the test bench, and 2 persons (sometimes even 4 persons) are required to lift and carry the large motor to be positioned on the motor test bench, so that the defects of high labor intensity and low work efficiency exist, and when hoisting equipment such as a crane is adopted, large equipment resources and operation sites are occupied, so that the operation is uneconomical.

[ utility model ]

The utility model aims to provide a lifting single-lifting device of a test motor carrying tool vehicle, which not only reduces labor intensity, but also improves working efficiency.

For this purpose, the utility model adopts the following technical scheme:

the utility model provides a single hoisting device of jacking of test motor handling tool car, by climbing mechanism and suspension mechanism constitution, suspension mechanism includes that the inner articulates at four-wheel dolly top and the cantilever jib outside the four-wheel dolly is extended to the outer end, climbing mechanism is including being vertical sleeve and the lifter of sliding in the sleeve, telescopic upper end is fixed at four-wheel dolly's top, the sleeve is stretched out to the upper end of lifter and contradict between the inner and the outer end of cantilever jib, the lower extreme confession of lifter is connected the lift power supply.

The upper end of the lifting rod is fixedly provided with a shaft seat, the shaft seat is provided with a supporting shaft, the supporting shaft is supported by a bearing, and the upper end of the lifting rod is abutted between the inner end and the outer end of the cantilever suspender through the bearing.

After the bearing is additionally arranged on the jacking mechanism, the upwarp and sagging functions of the single end of the cantilever suspender are optimized.

The lifting rod is also connected with a screw, a guide sliding hole is formed at the position corresponding to the screw along the axial direction of the sleeve, and the screw is in sliding fit with the guide sliding hole.

The screw that the lifter set up and the guide slide hole matched with structure that the sleeve offered have guaranteed the lift motion stationarity of lifter, and the circumferential deflection is stopped to the lift overall process.

The suspension mechanism consists of a frame beam fixed on the top surface of the four-wheel trolley, a hinge seat fixed on the top surface of the frame beam, a hinge pin and a cantilever suspender, wherein the inner end of the cantilever suspender is connected with the hinge seat through the hinge pin.

The utility model has the following beneficial effects:

when the external lifting capacity source is connected with the lower end of the lifting rod, the lifting rod can lift and slide along the sleeve, so that the working conditions of lifting and sagging of the single end of the cantilever boom are realized, the test motor can be lifted off the ground and carried along with the four-wheel trolley, and the operation can be completed by a single person, so that the labor is saved, the labor intensity is reduced, and the efficiency of the motor test preparation stage is improved.
