Abstract
The invention relates to an anti-misoperation device of an operating valve of a coal mine fully-mechanized coal mining hydraulic support. The anti-misoperation device comprises a limiting fixed plate, a limiting horizontal baffle and a locking loop bar. The locking loop bar is in a ring shape, the locking loop bar is hinged to the side portion of the limiting fixed plate and can rotate in a vertical plane, the limiting horizontal baffle is arranged on the lower portion of the locking loop bar, and the limiting horizontal baffle is fixedly connected with the side portion of the limiting fixed plate. According to the anti-misoperation device, the ring bar structure is adopted, the structure is simple, bolts are used on an operating valve set of the hydraulic support for fastening, workers can operate the device conveniently, time and labor are saved, the intrinsic safety of the hydraulic support is improved, and the recycling reuse rate can reach up to 100%.
Description
Technical field
The present invention relates to coal mine fully-mechanized mining hydraulic chock running valve anti-misoperation apparatus.
Background technology
At present, at present, hydraulic support can reliably and effectively support and control face roof, isolation goaf, prevent that spoil from scurrying into work plane, guarantee working space, and can mechanization move along with the propelling of work plane, constantly push coal-winning machine and drag conveyor to rib, thereby meet the requirement that work plane is highly efficient and productive and keep the safety in production.Therefore hydraulic support is one of key equipment in modern coal-mining technique.The hydraulic support that the current application feature most of hydraulic support coal enterprise is used mainly contains hydraulic shield support, standing shield hydraulic support; various model hydraulic chock running valves are without any latch-up protection; control valve handgrip is outside exposed; work plane personnel activity is frequent; light is darker; existence is because surprisingly touching the possibility that operating grip starts holder device; cause unnecessary injury; install operating grip safety interlock system additional; just can effectively avoid accidental activation support operating grip, serious threat is the face of the adopting staff of its lower work.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of coal mine fully-mechanized mining hydraulic chock running valve anti-misoperation apparatus.
Technical scheme of the present invention is: coal mine fully-mechanized mining hydraulic chock running valve anti-misoperation apparatus, comprise spacing fixed head, spacing horizontal baffle and locking loop bar, it is characterized in that: described locking loop bar is ring-type, the sidepiece of locking loop bar and spacing fixed head is articulated and connected, can in vertical plane, rotate, the bottom of locking loop bar is provided with spacing horizontal baffle, and spacing horizontal baffle is fixedly connected with the sidepiece of spacing fixed head.
Spacing fixed head of the present invention is provided with for fixing bolt.
Operating principle of the present invention is: the sidepiece that spacing fixed head is fixed on to operating valve, when hydraulic support operating operation valve handle is placed in meta (zero-bit), rotate locking loop bar by locking casing pipe sleeve on operating valve handle, by spacing horizontal baffle by locking loop bar horizontal lock.
The invention has the beneficial effects as follows: invention adopts ring bar structure, simple in structure, in hydraulic support operating valve group, adopts bolton, safe and reliable, staff is easy to operate, time saving and energy saving, improve hydraulic support intrinsic safety, and reclaimed reusability up to 100%.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
The specific embodiment
Coal mine fully-mechanized mining hydraulic chock running valve anti-misoperation apparatus, comprise spacing fixed head 1, spacing horizontal baffle 2 and locking loop bar 3, described locking loop bar 3 is ring-type, locking loop bar 3 is articulated and connected with the sidepiece of spacing fixed head 1, can in vertical plane, rotate, the bottom of locking loop bar 3 is provided with spacing horizontal baffle 2, and spacing horizontal baffle 2 is fixedly connected with the sidepiece of spacing fixed head 1.
Spacing fixed head 1 of the present invention is provided with for fixing bolt.
Operating principle of the present invention is: the sidepiece that spacing fixed head 1 is fixed on to operating valve, when hydraulic support operating operation valve handle is placed in meta (zero-bit), rotate locking loop bar 3 by locking casing pipe sleeve on operating valve handle, by spacing horizontal baffle 2 by locking loop bar 3 horizontal locks.
The invention has the beneficial effects as follows: the present invention adopts ring bar structure, simple in structure, in hydraulic support operating valve group, adopts bolton, safe and reliable, staff is easy to operate, time saving and energy saving, improve hydraulic support intrinsic safety, and reclaimed reusability up to 100%.
