Abstract
The invention relates to a hydraulic prop three-way valve insurance device which comprises a single hydraulic prop (5), a three-way valve (4) and a support (1). Two ends of the support (1) are bent, screwed holes (3) are arranged at the ends, bolts (2) are arranged in the screwed holes (3), and the screwed holes (3) are connected with two ends of the three-way valve (4) on the single hydraulic prop (5). By adopting the technical scheme, the hydraulic prop three-way valve insurance device has the advantages of being simple in structure, low in processing cost, convenient to install and dismantle, long in service life, capable of effectively preventing the three-way valve from flying off and the like.
Description
Technical field:
The invention belongs to the Safety of Coal Mine Production protector, be specifically related to hydraulic prop three-way valve safeties.
Background technology:
Increasing along with the coal mining degree of depth, the problem of impulsion pressure becomes increasingly conspicuous, hydraulic prop is the common equipment of coal-face and lame advanced supporting under the coal mine, yet hydraulic prop in use, because top board is pressed suddenly or pressure when big, three-way valve flies out easily, has major safety risks.Corner, sidewalk particularly, three-way valve is over against the pedestrian, and after three-way valve flew out, personnel can't avoid, and worker's life security in serious threat.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome the potential safety hazard that three-way valve flies out and causes on the hydraulic prop, a kind of hydraulic prop three-way valve safeties that provide.
To achieve these goals, the present invention has adopted following technical scheme:
Hydraulic prop three-way valve safeties, it comprises: hydraulic prop, three-way valve, support, and the bending of support two ends takes the shape of the letter U for 90 °, and the end of two ends bending is provided with screw, be respectively equipped with bolt in the screw, bolt is connected with three-way valve two ends on the hydraulic prop respectively.
Owing to adopted technique scheme, it is simple in structure to make that the present invention has, and processing cost is low, easy installation and removal, and long service life can effectively prevent advantages such as flying out of three-way valve.
For more detailed explanation the present invention, accompanying drawing provides a most preferred embodiment.
Description of drawings:
Fig. 1 is schematic three dimensional views of the present invention.
The specific embodiment:
As shown in Figure 1, a kind of novel hydraulic pillar three-way valve safeties, it comprises: hydraulic prop 5, three-way valve 4, support 1, and support 1 two ends bending takes the shape of the letter U for 90 °, and the end of two ends bending is provided with coaxial screw 3, be respectively equipped with bolt 2 in the screw 3, bolt 2 is connected with the two ends of three-way valve 4 on the hydraulic prop 5 respectively, as seen from the figure, and when three-way valve flies out, one end of support 1 namely keeps off on the hydraulic prop, has prevented flying out of three-way valve.
Owing to adopted technique scheme, it is simple in structure to make that the present invention has, and processing cost is low, easy installation and removal, and long service life can effectively prevent advantages such as flying out of three-way valve.
