Description

Technical Field

[0001] The utility model belongs to the technical field of single hydraulic props, and in particular relates to a single hydraulic prop supporting device. Background Art

[0002] Single hydraulic prop refers to a single retractable prop that uses liquid pressure to generate working resistance and achieve lifting and unloading. Single hydraulic props are mainly divided into suspended type, double telescopic suspended type, DN internal injection type and fiberglass single hydraulic prop;

[0003] A single hydraulic prop is composed of a cylinder, piston, and valves. The three-way valve is the heart of the external injection single hydraulic prop. It consists of a check valve, an unloading valve, and a safety valve. The check valve supplies fluid to the single hydraulic prop, the unloading valve unloads the prop back to the prop, and the safety valve ensures the single hydraulic prop maintains constant resistance. This article will use the external injection single hydraulic prop as an example to explain its structure and operating principle.

[0004] When the single hydraulic support is in use, it is installed inside the supporting device, so that the supporting device is used to support and fix the single hydraulic support. However, when the single hydraulic support is subjected to uneven force, the single hydraulic support squeezes the supporting device on one side, which can easily cause the supporting device to tilt, causing the supporting device to drive the single hydraulic support to tilt, and the single hydraulic support cannot make uniform contact with the supporting surface.

[0015] Beneficial effects

[0016] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0017] The utility model sets a stretching structure to limit the connection structure and the mounting plate. When the single hydraulic support body is subjected to force, the single hydraulic support body directly pushes the connection structure to move outward. In order to prevent the connection structure from rotating outward after being subjected to force, the stretching structure can pull the connection structure, thereby maintaining the stability of the single hydraulic support body after being subjected to force.
