Abstract
The utility model discloses an anti-flying hood for a headset type three-use valve with single prop. The anti-flying hood comprises two side steel plates; the two side steel plates are connected and fixed through a screw rod. The anti-flying hood overcomes the disadvantages in the prior art, and is simple in design and reasonable in structure; with the anti-flying hood for headset type three-use valve, through sufficient utilization of the advantage that the anti-flying hood is conveniently installed and disassembled, the labor production efficiency and the safety factor for preventing accidents are effectively improved, and good economical benefits and social benefits are created.
Description
Technical field
The utility model relates to technical field of safety devices, specifically belongs to the anti-cover that flies of a kind of headset style individual prop triple-use valve.
Background technology
The individual prop that colliery is used has the limit range of bearing pressure, and triple-use valve (safety valve) is safety factor key up to standard, and when pressure was excessive, safety valve can be opened automatically, exists and flies the potential safety hazard that valve is hurted sb.'s feelings.Coal mining enterprise's individual prop triple-use valve prevents that flying device totally has three kinds of (1) Plate Welding steel pipe sockets on triple-use valve at present, both sides connect fastening (2) Plate Welding half rounds shroud on triple-use valve by lead screw, both sides connect fastening (3) by lead screw hooks the triple-use valve two ends with the iron chains of two ends band hook, fastening with cottor pin in the middle of iron chains.Prevent flying all deficiencies of device for above three kinds, or affect production efficiency, or do not have the anti-effect that valve ensures safety that flies.When existing the individual prop fluid infusion or change post, the first device all to dismantle the problem of screw; The second device is convenient than the first when the individual prop fluid infusion, but has the problem of dismounting screw need to change post the time; The third device is comparatively simple, has cottor pin bearing tension deficiency, does not have the anti-problem that flies effect.
The utility model content
The purpose of this utility model has been to provide the anti-cover that flies of a kind of headset style individual prop triple-use valve, the deficiencies in the prior art have been overcome, simplicity of design, rational in infrastructure, adopt the anti-device that flies of " headset style " triple-use valve, it is convenient to install and pluck the advantage of unloading by abundant profit, effectively improves labor productivity and trouble-saving safety factor, creates good economic benefit and social benefit.
The technical solution adopted in the utility model is as follows:
The anti-cover that flies of a kind of headset style individual prop triple-use valve, the described anti-cover that flies contains two side steel plates, by lead screw, is connected and fixed between the steel plate of both sides.
Two described side steel plate two ends all are circular-arc, and a head breadth, one are narrow, and narrow end has threaded connection hole.
Described side steel plate inboard all is welded with the semicircle steel pipe.
Described lead screw is the Bidirectional screw bar.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model only connects fastening two steel plates in a side by lead screw, in manufacturing process, be convenient to installation, when individual prop needs fluid infusion or changes, can pluck and unload fast, without the dismounting screw, the operation that greatly simplifies the operation, by labor productivity, is created good economic benefit and social benefit; Steel plate two ends, both sides used all are circular-arc, the phenomenon that can effectively avoid the scratch operating personnel or scratch operating personnel's clothes in process of production, and the steel plate lower end is narrower is conducive to save working space; The inboard welding of steel plate semicircle steel pipe, can block cylindrical monomer triple-use valve fully, and difficult drop-off; Bidirectional-screw used, be conducive to member and disperse to carry, and Assembling, be convenient to transportation, when certain member damages, conveniently with spare part is on-the-spot, changes.And it is strong by lead screw, to be connected and fixed two steel plate bearing capacities, can effectively prevent from flying valve.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model effect figure.
The specific embodiment
Referring to accompanying drawing, the anti-cover that flies of a kind of headset style individual prop triple-use valve, the anti-cover that flies contains two side steel plates 1, two described side steel plate 2 two ends all are circular-arc, and a head breadth, one are narrow, and narrow end has threaded connection hole 101, and side steel plate 1 inboard all is welded with semicircle steel pipe 102.Between both sides steel plate 1, be connected and fixed by Bidirectional screw bar 2.Bidirectional screw bar 2 connects fastening two side steel plates 1 and forms the anti-cover that flies of headset style individual prop triple-use valve.Fig. 2 is that headset style individual prop triple-use valve 3 prevents flying to cover on the effect figure on individual prop 4.
