Abstract
The utility model relates to an anti-impact hydraulic support. By the hydraulic support, roadway reinforced supporting degree can be effectively improved, daily roadway deformation is reduced, and most impact energy can be resisted and buffered during impact ground pressure, so that the safety of personnel and equipment is ensured. The technical scheme is that the hydraulic support comprises top beams, bases and jack upright posts, wherein upper spherical column caps are arranged on the lower parts of the top beams; lower spherical column shoes are arranged on the upper parts of the bases and provided with the jack upright posts; and adjusting rods are connected between the jack upright posts and the upper spherical column caps. The hydraulic support has a simple structure, is low in manufacturing cost, economic and practical and convenient to transport, assemble and disassemble, has high adaptability to roadway deformation, high supporting strength and a good roadway reinforced supporting effect which is superior to that of a single column and a carrying framed timber, adapts to an area with impact ground pressure and is high in safety performance, and a top plate can be effectively controlled to be pressed and sunk.
Description
Technical field
The utility model relates to bump mine support equipment, particularly a kind of erosion control hydraulic support.
Background technology
The daily mine pressure of bump mine is big, and roadway deformation is serious, often the tunnel is produced considerable damage when bump takes place, cause crush, base plate is heaved etc., harm staff safety, destruction work equipment brings about great losses.
Summary of the invention
To above-mentioned situation; For overcoming the defective of prior art; The purpose of the utility model provides a kind of erosion control hydraulic support for the bump mine exactly, can effectively solve roadway support and strengthen degree, reduces daily roadway deformation amount; When bump takes place, can resist and cushion most of impact energy, thereby guarantee the problem of personal security and equipment.
The technical scheme that the utility model solves is; Comprise back timber, base and jack column, the spherical cap of going up is arranged below the back timber, spherical post footwear are down arranged above the base; On the spherical post footwear jack column is housed down, is connected with adjusting rod between jack column and the last spherical cap.
The utility model is simple in structure, and cost is low, and is economical and practical; The transportation assembling and disassembling is convenient, and strong to roadway deformation compliance, supporting intensity is big; It is good that supporting effect is strengthened in the tunnel, is superior to monomer column, lifts the canopy supporting, and more adapting to has the bump zone; Can effectively control the top board pressurized, security performance is high.
Description of drawings
Fig. 1 is the structural front view of the utility model;
Fig. 2 is the structure left view of the utility model;
Fig. 3 is the structural front view of the H type support of the utility model;
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Can find out by Fig. 1-3; The utility model comprises back timber, base and jack column, and the spherical cap 5 of going up is arranged below the back timber 1, and spherical post footwear 6 are down arranged above the base 3; On the spherical post footwear 6 jack column 2 is housed down, is connected with adjusting rod 4 between jack column 2 and the last spherical cap 5.
For guaranteeing result of use, described back timber 1 is a case structure with base 3.
Described back timber 1 respectively has two with base 3, is contained in respectively on the corresponding H type hydraulic support.
Described jack column 2 has two, connects with cross struts 7 between two jack column A 2a and the jack column B 2b, constitutes H type hydraulic support.
Described adjusting rod 4 generally have 5 grades adjustable, connect with bearing pin respectively.
Move towards the center along the tunnel when support is installed and install, every bridge joint ceiling U type capplce is according to the underworkings actual height; Earlier adjusting rod is transferred to suitable gear; With wire rope, wire clips set cap is strapped on the U type side plates then, two every, carries out anti-down measure.
Then needing to move towards both sides along the tunnel when H type support is installed installs.
This utility model is simple in structure, and cost is low, and is economical and practical, and the transportation assembling and disassembling is convenient, and is strong to roadway deformation compliance.Supporting intensity is big, and it is good that supporting effect is strengthened in the tunnel, is superior to monomer column, lifts the canopy supporting, and more adapting to has the bump zone, can effectively control the top board pressurized.
