The limit device disclosed by the invention is reasonable in design, simple in structure, easy to manufacture, convenient to mount, and convenient for working staff to operate; the limit device improves the safety and reliability of a hydraulic support, and is high in safety coefficient and universality, can be generally applied to hydraulic-support control valves of various types and at various positions, and can be recycled.
Description
Technical field
The present invention relates to a kind of coal mine hydraulic supporting control valve hand meta locking safety caging device.
Background technology
Hydraulic support is the main support apparatus that modern large automatic coal mine work area adopts, the working space that its work plane is operating worker and coal-winning machine, drag conveyor provides a safety.Hydraulic support has lot of advantages, and main is the roof caving that can prevent in working space, and the safety of protection work plane inner machine and personnel, provides safety guarantee for realizing work plane automation further.
Along with the extensive use of hydraulic support, in mining face under mine actual production, each action of hydraulic support is controlled by control valve mounted thereto, require that the rigging position of hydraulic chock running valve group should be convenient to human users, operating space can not be too narrow, if hydraulic chock running valve handle is outside exposed, without any protected mode, staff will be there is like this in walking, in carrying and work progress, control valve hand is surprisingly being pulled, scrape, touch, the possibility that the form such as to stumble produces misoperation and causes the accident, the situation of control valve handle misoperation will be there is, thus serious threat is to the safety in production of coal mine work area, or cause unnecessary personal injury, install control valve hand additional meta locking safety caging device, just can realize hydraulic support essential safety in use, initiatively prevention, avoid operating valve hand non-artificial misoperation, eliminate the potential safety hazard brought thus.
Summary of the invention
The object of the invention is to the invention provides a kind of coal mine hydraulic supporting control valve hand meta locking safety caging device, realize essential safety, initiatively prevention, prevents the non-artificial misoperation of operating valve, all kinds of accidents of generation.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of coal mine hydraulic supporting control valve hand is meta locking safety caging device, comprise two spacing fixed heads, two spacing slide bars, two lock nut, described two spacing fixed heads are equipped with two locating holes for set bolt, for two spacing fixed heads being separately fixed at the both sides of operating valve vavle shelf, described two spacing fixed heads all there are two slideways and two stopper slots, described two spacing slide bars are one end screw type stay bolt, be located in the slideway on two spacing fixed sides respectively, described two lock nut are installed on the leading screw end of two spacing slide bars respectively, for fastening spacing slide bar.
Preferably, above-mentioned two spacing fixed heads are equipped with two locating holes for set bolt.
Preferably, above-mentioned spacing fixed head is equipped with two slideways and two stopper slots, and slideway is corresponding with stopper slot position.
Preferably, above-mentioned two spacing slide bars are one end screw type stay bolt, are located in respectively in the slideway on two spacing fixed sides.
Preferably, above-mentioned two lock nut are installed on the leading screw end of two spacing slide bars respectively, for fastening spacing slide bar.
Operating principle of the present invention: when operating valve end of operation or support maintenance, hydraulic support operation operating valve handle is placed in meta, and the two spacing slide bars that slide are placed at slideway bottom simultaneously, thus realize the meta locking of operating valve hand handle; Need action hydraulic support, the two spacing slide bars that slide are placed in the stopper slot of slideway upper end simultaneously, realize operating valve hand unlocking, thus control each pillar, jack action of hydraulic support.
The invention has the beneficial effects as follows: this apparatus design is reasonable, structure is simple, make easily, easy for installation, operated by personnel is convenient, improves the security reliability of hydraulic support, safety factor is high, highly versatile, generally can be applied on the hydraulic chock running valve of various model and each position, and can reclaim Reusability.
