Abstract
The utility model relates to a hydraulic support operating valve especially relates to a protector is controld to hydraulic support operating valve mistake. The utility model discloses a loop type lockpin, the ARC end one end of loop type lockpin is passed through the fixing clip and is fixed on the valve plate, and another ARC end is spacing through the baffle of fixing on the valve plate of operating valve. The utility model discloses a loop type lockpin passes through rotatory spacing, the locking of realizing the control handle of valve plate overhead gage, and simple structure can stop the maloperation messenger support production malfunction that the collision of human factor or object led to the fact, eliminates and gives the colliery downhole safety production potential safety hazard of bringing.
Description
Technical field
This utility model relates to a kind of hydraulic chock running valve, particularly relates to a kind of hydraulic chock running valve error operations preventer.
Technical background
Hydraulic support is in use, ensure that the equipment of fully-mechanized mining working runs well, after current hydraulic support mixes up, handle valve and be in zero-bit state, after hydraulic support enters constant-resistance working stage, back timber keeps good contacting with top board, safeguard the top board above support and scratch board conveyor, ensure normal coal mining activity and the coal-winning machine of coal miner, the working face equipments such as scratch board conveyor run well, now handle valve and there is no mechanical self-latching in zero-bit state, if now owing to coal miner walks between support or the factor such as object collision, manipulation valve control crank action can be caused, it is likely to result in hydraulic support, drag conveyor misoperation, cause device damage or bring hidden danger to safety in production. the appearance of these situations can result in the generation of mine safety accidents.
Utility model content
This utility model is to solve a kind of hydraulic chock running valve error operations preventer of the problems referred to above offer. This device can effectively prevent hydraulic chock running valve faulty operation from causing support unstability or support misoperation, stop anthropic factor or maloperation that object collision causes and keep the safety in production the potential safety hazard brought to underground coal mine.
Technical solution is:
A kind of hydraulic chock running valve error operations preventer, including ring-like lock pin, arc end one end of described ring-like lock pin fastens on valve plate by fixing, and another arc end is by being fixed on the baffle limiting on the valve plate handling valve.
Described ring-like lock pin can rotate in the draw-in groove of fixing card.
Advantage of the present utility model and effect be:
This utility model adopts ring-like lock pin to be rotated spacing, the locking that realize control crank by valve plate overhead gage, simple in construction, can stop anthropic factor or maloperation that object collision causes makes support produce misoperation, eliminate and keep the safety in production brought potential safety hazard to underground coal mine.

Detailed description of the invention
Arc end one end of the ring-like lock pin 5 of this utility model is fixed on valve plate 4 by fixing card 6, and ring-like lock pin 5 can rotate in fixing card 6 draw-in groove; Another arc end is spacing by being fixed on the baffle plate 7 handled on valve valve plate 2.
1, when handling valve and being in middle position, ring-like lock pin 5 is fixed on valve plate 4 by fixing card 6, is contained on the manipulation left valve plate 2 of valve with bolt 8 Guan County, handles the left valve plate 2 of valve and is arranged on the left of manipulation valve 1. Baffle plate 7 is fixed on the manipulation right valve plate 3 of valve by bolt 9, handles the right valve plate 3 of valve and is arranged on the right side of manipulation valve. Tight a bolt 9 under original state, ring-like lock pin is latched in and handles in the space that the right valve plate of valve 3 and baffle plate 7 are formed thus realizing blocking function, it is achieved handle valve 2 handle space spacing.
2, using and unclamp bolt 9 during state, pushed inward by ring-like lock pin 5, after baffle plate 7 half-twist, ring-like lock pin rotates 180 �� around fixing card 6, handles valve handle and realizes all function actions of fully-mechanized mining working surface hydraulic support.
3, after hydraulic support is handled, rotary ring-shaped lock pin 5 so that it is right-hand member is on the manipulation right valve plate 3 of valve, and baffle plate 7 tights a bolt 9 after rotating 90 ��, it is achieved blocking function.
Claims (2)
