High-stability hydraulic jack with cleaning function

Abstract

The invention relates to a high-stability hydraulic jack with a cleaning function. The high-stability hydraulic jack comprises a cylinder body and a plunger and further comprises a cleaning mechanismand two or more supporting mechanisms, each supporting mechanism comprises a supporting rod, a moving block, a rotating rod, a limiting block, a limiting rod, a screw rod, a knob, two mounting bearings, two connecting rods and two fixing blocks, the cleaning mechanism comprises a cleaning strip and two or more mounting assemblies, each mounting assembly comprises a mounting seat, columnar notch, afixing rod, a mounting block and two or more fixing units, and the fixing units comprise mounting holes and ball screws. According to the high-stability hydraulic jack with the cleaning function, thepressure bearing area of the hydraulic jack can be increased through the supporting mechanisms, thus the probability of falling and sliding of the hydraulic jack is decreased, and the stability of the hydraulic jack is improved; and the plunger can be cleaned through the cleaning mechanism, thus abrasion of the plunger is relieved, the sealing performance of the hydraulic jack is improved, and the failure rate of the hydraulic jack is decreased.

Description

technical field [0001] The invention relates to the field of hydraulic equipment, in particular to a high-stability hydraulic jack with a cleaning function. Background technique [0002] A hydraulic jack refers to a jack that uses a plunger or a hydraulic cylinder as a rigid jack. It has the characteristics of compact structure, stable operation, large supporting force, and self-locking. The hydraulic jack has a strong supporting capacity, and the supporting capacity of the heavy-duty hydraulic jack exceeds 100t. [0003] The bottom area of ​​the hydraulic jack in the prior art is small, so the pressure-bearing area of ​​the hydraulic jack is small, so that the hydraulic jack is prone to sinking or sliding when lifting heavy objects, which increases the probability of accidents. Not only that, If a large amount of dust and impurities are accumulated on the plunger of the hydraulic jack in the prior art, the dust and impurities will cause the plunger to wear during the move...

[0003] The bottom area of ​​the hydraulic jack in the prior art is small, so the pressure-bearing area of ​​the hydraulic jack is small, so that the hydraulic jack is prone to sink or slide when lifting heavy objects, which increases the probability of accidents. Not only that, If a large amount of dust and impurities are accumulated on the plunger of the hydraulic jack in the prior art, the dust and impurities will cause the plunger to wear during the movement of the plunger, thereby reducing the sealing performance of the hydraulic jack and causing the hydraulic jack to fail
