Problems solved by technology

[0002] The existing single hydraulic prop is large in size and takes up a lot of space, and the number of components of the existing single hydraulic prop is large, and the disassembly is cumbersome. After a failure, maintenance is troublesome, waste of manpower and material resources, and the existing single hydraulic prop uses a three-purpose valve. , its structure is complex, easy to bend, easy to corrode, and has a high failure rate, which cannot meet the current underground use conditions;
[0003] The existing technology faces problems: the space occupied by the single hydraulic prop in the mine, and the effective area of ​​the prop used in the underground is small; the three-purpose valve is installed vertically to the single hydraulic prop, which occupies a large area, has a complex structure, and has a high failure rate

Abstract

The invention relates to a modular single hydraulic prop. In order to solve the problems that a prop is large in size and occupied space, after a fault occurs, maintenance is troublesome, and manpower and material resources are wasted, a movable column module, a cylinder barrel module and a valve set module are arranged, wherein the cylinder barrel module comprises a hoop valve seat, a cylinder barrel, a base, a handle and an L-shaped notch connecting pipe; the movable column module comprises a top cover, a movable column, a hoop, a dustproof telescopic sleeve, a spring lower connecting device, a reset spring, a spring upper connecting ring and a limiting ring; and the valve set module comprises a valve set protective sleeve, a liquid inlet valve and a safety valve which are longitudinally designed. An original transverse three-purpose valve is replaced, and the effects that the size is reduced, and after a fault occurs, maintenance is convenient are achieved.

Description

technical field [0001] The invention relates to underground supporting supplies for coal mines, in particular to a modular single hydraulic prop. Background technique [0002] The existing single hydraulic prop is large in size and takes up a lot of space, and the number of components of the existing single hydraulic prop is large, and the disassembly is cumbersome. After a failure, maintenance is troublesome, waste of manpower and material resources, and the existing single hydraulic prop uses a three-purpose valve. , its structure is complex, easy to bend, easy to corrode, and has a high failure rate, which cannot meet the current underground use conditions; [0003] The existing technology faces problems: the space occupied by the single hydraulic prop in the mine, and the effective area of ​​the prop used in the mine is small; the three-purpose valve is installed vertically to the single hydraulic prop, which occupies a large area, has a complex structure, and has a high...
