Embodiment Construction

[0016] like figure 1 Shown is the preferred embodiment of the heavy-duty hydraulic lifting device of the present invention.

[0017] The heavy-duty hydraulic lifting device includes a push rod 1, a cylinder 2 and a piston 3, and also includes a limit rod 4, which is fixedly connected with the piston 3, and moves along with the piston 3 along the Cylinder 2 slides axially.

[0018] In this embodiment, the heavy-duty hydraulic lifting device further includes a guide belt 5 installed between the cylinder 2 and the piston 3 .

[0019] In this embodiment, the heavy-duty hydraulic lifting device further includes a sealing ring 6, which is installed between the cylinder 2 and the piston 3, and the cross section of the sealing ring 6 is "Y". "type.

[0020] Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on t...

Abstract

A heavy-load hydraulic lifting device comprises a push rod (1), a cylinder tube (2) and a piston (3) and is characterized by further comprising a limit rod (4). The limit rod (4) is fixedly connected with the piston (3). The piston (3) axially slides along the cylinder tube (2). The heavy-load hydraulic lifting device has the advantages that by the added limit rod (4), the inclination of an automobile carriage can be controlled during lifting, and automobile carriage lifting safety is increased while heavy load is increased.

Description

technical field [0001] The invention relates to a lifting device, in particular to a heavy-duty hydraulic lifting device. Background technique [0002] At present, the heavy-duty hydraulic lifting devices on automobiles do not have intermediate stop structure facilities. Therefore, during the lifting process, the inclination of the automobile compartment cannot be controlled, which is not only a waste of time, but also very dangerous under heavy load conditions. Contents of the invention [0003] In order to solve the technical problem that the current automobile cannot control the inclination of the car compartment because the hydraulic lifting device has no stop structure facilities, the invention provides a heavy-duty hydraulic lifting device. [0004] The technical scheme that the present invention adopts is as follows: [0005] A heavy-duty hydraulic lifting device includes a push rod, a cylinder, and a piston, and also includes a limit rod, which is fixedly connect...
