Abstract
The utility model relates to a hydraulic support main control valve protection device which comprises a cover plate. The left side and the right side of the cover plate are respectively provided with a side plate. The cover plate is fixedly connected with the side plates through pin shafts. A pipe ring is arranged on the cover plate. The hydraulic support main control valve protection device has the advantages of being simple in structure, low in manufacture cost, and capable of preventing coal dust and gangue from falling on a hydraulic support main valve, preventing coal dust from covering the surface of the hydraulic support main control valve and influencing the flexibility of the hydraulic support main valve and preventing gangue from falling on the hydraulic support main control valve, damaging the hydraulic support main control valve in a crashing mode and influencing the utilization function of the hydraulic support main control valve, reducing the occurrence rate of hydraulic injury accidents under the shaft, achieving the purpose that the hydraulic support main control valve of a remanufactured support detects the life service of parts such as valve blocks through detachment and washing, greatly reducing material waste, and being more capable of embodying the purposes of saving energy and material, being efficient and protecting the environment of remanufacture.
Description
Technical field
The utility model relates to a kind of hydraulic support main control valve protector.
Background technology
At present, in the manufacture process again of hydraulic support, find that the hydraulic fittings dismantling has rusty stains, the joint corrosion of the sebific duct being connected with valve or elbow is serious, cannot adopt the method for non-damage type to be disassembled at all, hydraulic support main control valve group surface is due to the accumulation of coal dust, its valve body can not bear the pumping plant intensity of pressure again, in the manufacture process again of hydraulic support, hydraulic support main control valve can only be judged to be and scrap, the hydraulic support main control valve group more renewing.
Utility model content
The utility model, in order to make up the defect of prior art, provides hydraulic support main control valve protector a kind of simple in structure, easy to use.
The utility model is achieved by the following technical solution:
A hydraulic support main control valve protector, comprises cover plate, and side plate is equipped with respectively in the described cover plate left and right sides, and cover plate is fixedly connected with by bearing pin with side plate, on described cover plate, pipe ring is housed.
Further, described bearing pin locks by cottor pin.
Further, described side plate is positioned at the lower end of the cover plate left and right sides, and the top of its two blocks of side plates is connected with cover plate two ends respectively.
The beneficial effects of the utility model are: simple in structure, cost is lower, can resist coal dust, spoil drops on hydraulic support main control valve, prevent coal dust from covering hydraulic support main control valve surface and affect the flexibility ratio of hydraulic support main control valve, also preventing that spoil from dropping on injures hydraulic support main control valve by a crashing object on hydraulic support main control valve, affect the use function of hydraulic support main control valve, reduce the incidence of the hydraulic pressure injury accident of down-hole, the hydraulic support main control valve that support is manufactured in realization is again by disassembling, clean, detect the life cycle of valve block component, greatly reduce the waste of material, more can embody manufacture again energy-conservation, material-saving, efficiently, the aim of environmental protection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 cover plate, 2 bearing pins, 3 side plates, 4 pipe rings, 5 cottor pins.
The specific embodiment
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure are partly known technology.
