Abstract
The utility model discloses a kind of for hydraulic chock running valve hand upper safety caging device, this device is made up of upper mounting plate, lower installation board and limitting casing, one end of described limitting casing and described upper or lower installation board is hinged, the other end is fixed on described time or upper mounting plate, and by hydraulic chock running valve hand being placed in limitting casing, described upper mounting plate and lower installation board are equipped with the installing hole mated with hydraulic chock running valve.The utility model has easy to operate, simple and ingenious structure, with low cost, the hydraulic support that can be applicable to different model, effectively can avoid the generation of device damage and the personnel casualty accidents caused because of handle maloperation.
Description
Technical field
The utility model belongs to coal mine underground hydraulic support frame device security operation technique field, especially relate to a kind of for hydraulic chock running valve hand upper safety caging device.
Background technology
At present, hydraulic support can reliably and effectively support and control face roof, every empty goaf, prevent spoil from scurrying into work plane, ensure working space, and mechanization can move along with the propelling of work plane, constantly push coal-winning machine and drag conveyor to rib, thus meet the requirement of the highly efficient and productive and safety in production of work plane, therefore, hydraulic support is one of key equipment in modern coal-mining technique.Because underground coal mine coal-face operating space environment is narrow, the position that operating valve set function requires again it to install will be beneficial to human users, can not be too hidden.Therefore often occur hydraulic support hand because surprisingly to be scraped, the form such as extruding and produce misoperation and cause the accident, thus damage equipment impact is produced, and even personal injury accident occurs.
In order to avoid the generation of above-mentioned accident, improve the security performance that hydraulic support normally uses at underground coal mine, prevent hydraulic support from by people's maloperation, unnecessary accident being occurred in down-hole, ensure the personal safety situation of the on-the-spot coal miner of mining face under mine, therefore the various hydraulic support operator that prevents arises at the historic moment the device of maloperation.
Summary of the invention
The utility model discloses a kind of brand new for hydraulic chock running valve hand upper safety caging device, it is simple that this device has structure, designs ingenious, process easy to use.
The technical solution of the utility model is: a kind of for hydraulic chock running valve hand upper safety caging device, be made up of upper mounting plate, lower installation board and limitting casing, one end of described limitting casing and described upper or lower installation board is hinged, the other end is fixed on described time or upper mounting plate, and by hydraulic chock running valve hand being placed in limitting casing, described upper mounting plate and lower installation board are equipped with the installing hole mated with hydraulic chock running valve.
As a kind of preferred embodiment, upper end and the upper mounting plate of described limitting casing are hinged.
As a kind of preferred embodiment, described lower installation board front portion is confined planes, and described limitting casing lower end is fixed on confined planes soffit.
As a kind of preferred embodiment, described limitting casing is rectangular configuration, and the width of described lower installation board confined planes is no more than the width of limitting casing, limitting casing lower end cross bar and two side levers can as the handles on limitting casing, facilitate the fastening of limitting casing and lower installation board and be separated, especially underground coal mine coal-face operating space is met narrow, and requirement that can not be too hidden.
As a kind of preferred embodiment, described limitting casing is U-shaped structure, and the width of described lower installation board confined planes is equal with the width of limitting casing.
As a kind of preferred embodiment, described upper mounting plate is provided with the duct run through for limitting casing upper end.
Operating principle of the present utility model is: for limitting casing and upper mounting plate hinged, this limiting and fixing device is arranged on underground coal mine coal face hydraulic support control valve, when hydraulic chock running valve is transferred to suitable gear by handle, limitting casing is put down, limitting casing lower end cross bar is made just to be fixed on lower installation board confined planes soffit, make hydraulic chock running valve handle sleeve in limitting casing, avoid hand handle because surprisingly being scraped, forms such as extruding and produce the generation of misoperation accident, when needs adjustment hand time, the limitting casing lower end cross bar be fixed on lower installation board is outwards moved and lifts, adjustment handle, cover is put down again solid after adjustment.
Structure of the present utility model is simple, compact volume and convenience, with low cost, lighter weight, be applicable to very much underground coal mine coal-face operating space narrow, and requirement that can not be too hidden, the utility model is arranged on underground coal mine coal face hydraulic support control valve, can not additionally take up space, small volume and less weight, people's independent operation can be realized, remarkable in underground coal mine coal-face result of use, effectively prevent the generation of device damage and the personnel casualty accidents caused because of handle maloperation.
