Abstract
The present invention relates to hydraulic prop technical field, disclose a kind of anti-winged device of individual prop triple-use valve, including semicircular body A and body B, described body A is provided with the cavity that three face baffle plates are formed, described body B is provided with the plate corresponding with body A cavity, perforate is all provided with described cavity and the medium position of plate, described body B plate perforate is built with bearing pin.Present invention employs two semicircular bodies, conveniently it is installed on the triple-use valve of hydraulic prop；A relatively closed space is formed after installing, even if will not also form winged valve when the valve element of triple-use valve breaks down under high pressure, has ensured the personal safety of underground construction worker；Simple and practical, small volume is easy to carry and installed, and has ensured production safety.
Description
Technical field
The present invention relates to the anti-winged device of individual prop technical field, more particularly to a kind of individual prop triple-use valve.
Background technology
Core component of the triple-use valve as hydraulic prop, the life-span of hydraulic prop is directly affected again and is made
With.Triple-use valve is the key component of hydraulic prop, and it plays a part of liquid filling pole-raising, overload overflow, lets out load drop post.Three use
Valve is located on hydraulic prop, and hydraulic prop is internally provided with pressure acting chamber.Hydraulic prop is with pump
Stand as power source, setting prop is realized by pipe-line system and fluid injection gun, triple-use valve is opened by unloading hand handle when pillar reclaims
Feather valve, intracavity liquid spray into goaf, realize prop drawing.When coal-face machine air way mouth, trident door, four fork doors use monomer
During hydraulic prop, though requiring parallel to rib, triple-use valve is still against employee's body；Triple-use valve has the limit model for bearing pressure
Enclose, when pressure is excessive, safety valve can automatically turn on, so as to the potential safety hazard that winged valve is hurted sb.'s feelings, this serious threat easily occur
The personal safety of mining area workmen, because underground coal mine hydraulic prop usage amount is larger, three in hydraulic prop
It is difficult to effectively control with the valve casualty accident that flies out.
The content of the invention
The present invention easily occurs flying the shortcomings that valve is hurted sb.'s feelings for triple-use valve in the prior art, there is provided a kind of individual prop three is used
The anti-winged device of valve.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
A kind of anti-winged device of individual prop triple-use valve, including semicircular body A and body B, described body A are provided with three
The cavity that face baffle plate is formed, described body B are provided with the plate corresponding with body A cavity, described cavity and plate
Medium position at be all provided with perforate, described body B plate perforate is built with bearing pin.
Preferably, described bearing pin end is provided with screw thread, the fixing bolt matched with screw thread is additionally provided with.
Preferably, described cavity dam and plate are all connected by welding on body A and body B, whole part
For stainless steel.
The present invention has significant technique effect as a result of above technical scheme：Employ two semicircular sets
Body, conveniently it is installed on the triple-use valve of hydraulic prop；A relatively closed space is formed after installing, even if triple-use valve
Valve element will not also form winged valve when break down under high pressure, ensured the personal safety of underground construction worker；Structure
Simple and practical, small volume is easy to carry and installed, and has ensured production safety.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
The toponym that each number designation is referred in accompanying drawing is as follows：1-body A, 2-body B, 3-cavity, 4-gear
Plate, 5-plate, 6-perforate, 7-bearing pin, 8-bolt.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of anti-winged device of individual prop triple-use valve, as illustrated, including semicircular body A1 and body B2, it is described
Body A1 be provided with three face baffle plates 4 formed cavity 3, described body B2 be provided with it is corresponding with body A1 cavity 3
All be provided with perforate 6 at the medium position of plate 5, described cavity 3 and plate 4, described body B2 plate perforate 6 built with
Bearing pin 7.The described end of bearing pin 7 is provided with screw thread, is additionally provided with the fixing bolt 8 matched with screw thread.The baffle plate 4 of described cavity 3
All it is connected by welding on body A1 and body B2 with plate 5, whole part is stainless steel.
After on triple-use valve installation hydraulic prop, three will be nested into corresponding to the body A1 and body B2 of anti-winged device
With on valve, the perforate 6 of corresponding both sides, bolt 8 is tightened after passing through perforate 6 with bearing pin 7, complete to fix.When triple-use valve need dismounting,
During maintenance, anti-winged device can be taken down by turning on bolt 8, simple and safe.
In a word, presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent be the foregoing is only
Change and modification, it should all belong to the covering scope of patent of the present invention.
