Problems solved by technology

Mechanical jacks are inflexible to use and inconvenient to carry; hydraulic jacks are easy to use and have a wide range of applications
The lifting height of existing jacks is between 10-30cm, which cannot meet the needs of use
Moreover, the existing lifts are all installed with upright oil pumps. At the same time, the chain is used as a transmission to drive heavy objects to lift. This increases the mechanical structure, increases the overall weight, and increases the transmission force. consumption

Embodiment 1

[0026] An inverted hydraulic movable lift, characterized in that it includes a mast, a load-bearing mechanism, a support leg and an oil pump, the bottom of the mast is vertically fixed to one end of the support leg, forming an L shape with the support leg, and the upper part of the mast is fixed There is an oil pump whose central axis coincides with the central axis of the mast. The oil pump includes a valve core and a sliding sleeve. Both sides of the sliding sleeve are fixed with connection ends, which are fixedly connected to the top of the mast through the connection end. The valve core is located at the lower part of the sliding sleeve. And it is between the masts, forming an inverted oil pump, the end of the valve core is fixedly connected with the load-bearing mechanism, the sliding sleeve is also provided with a hydraulic oil hole, and the oil pump has at least one section.

[0027] The oil pump can also be movably fixed on the door frame, the top of the door frame is p...

Abstract

The invention relates to an inverse hydraulic movable lifter and an use method thereof. The lifter is of a separated structure, and comprises a travelling wheel, a portal, a support mechanism, supporting legs and an oil pump. The supporting legs are fixedly connected with the portal, the oil pump drives the support mechanism to move vertically along the portal, and the oil pump is fixedly connected with the support mechanism. The inverse hydraulic movable lifter and the use method thereof have the advantages that the separated structure is adopted, so that the transport is more convenient, the occupation space is small, and field assembly is facilitated; the oil pump and the portal are of a separated structure, so that separated transporting and temporary assembling are achieved; at the same time, the oil pump maintenance and part replacement are facilitated; the oil pump is used for lifting, the lifter is lifted to a certain height, a user can conveniently move, and both time and labor are saved. The whole structure is simple, the size is small, and the use is flexible and convenient.

Description

technical field [0001] The invention relates to a lift, in particular to an inverted hydraulic movable lift and its usage method. Background technique [0002] At present, the lifts used in the maintenance industry mainly use fixed lifts, which are inconvenient to move, and cannot be effectively solved for some special occasions. At present, mobile lifts are mainly mechanical or hydraulic jacks. Mechanical jacks are inflexible to use and inconvenient to carry; hydraulic jacks are easy to use and have a wide range of applications. The lifting height of existing jacks is all between 10-30cm, which cannot meet the use requirements. Moreover, the existing lifts are all installed with upright oil pumps. At the same time, the chain is used as a transmission to drive heavy objects to lift. This increases the mechanical structure, increases the overall weight, and also increases the transmission force. consumption. Contents of the invention [0003] In order to overcome the de...
