Abstract
The invention discloses a drill rod hole sealing device for coal mine punching and relates to a sealing device. The sealing device is composed of a sealing part and a fixing part connected to the periphery of the sealing part, wherein the fixing part is fixedly connected with the periphery of a drill rod hole, the sealing part is made of an elastic material and is of a ripple structure provided with continuous crests and troughs, an annular sealing lip allowing a punching drill rod to penetrate through is arranged on the sealing part, the sealing surface of the sealing lip is matched with the peripheral surface of the punching drill rod, and a supporting frame is arranged inside the sealing lip. The sealing device is used for punching of a coal mine, can seal the drill rod hole and is good in sealing effect.
Description
Technical field
The present invention relates to a kind of sealing device, be specifically related to drilling rod hole sealing device for the punching of a kind of colliery.
Background technology
Along with coal mining difficulty is increasing, Gas Outburst problem is also more and more serious, and for head it off, present stage, ideal method adopted punching technology exactly.First in coal seam, hole, then in the gas extraction hole having bored, inject water under high pressure, inside, coal seam is washed into cavity, effective like this bore diameter that increased, has strengthened gas permeability of coal seam, is conducive to gas and discharges.But, in punch process, can produce a large amount of methane gas and water, cinder and coal dust fluid-mixing, this just needs gathering-device to collect above-mentioned gas and fluid-mixing.In punch process, along with swing and the rotation of drilling rod, between drilling rod and gathering-device, seal badly, the fluid-mixing of water, cinder and coal dust composition easily flows out gathering-device along drilling rod, affects collecting effect, makes punching place environment become severe.
Summary of the invention
Object of the present invention is just to provide drilling rod hole sealing device for a kind of colliery punching, between itself and drilling rod, can closely cooperate, and is applied in gathering-device, can improve the sealing between drilling rod and gathering-device.
For achieving the above object, technical scheme of the present invention is: drilling rod hole sealing device for the punching of a kind of colliery, sealing device is made up of sealing and the fixed part that is connected to sealing surrounding, fixed part is fixedly connected with drilling rod hole surrounding, described sealing be elastomeric material make there is continuous crest and the ripple struction of trough, on sealing, be provided with the annular seal lip passing for punching drilling rod, the outer circumference surface of the sealing surface of sealing lip and punching drilling rod matches, and is provided with support frame in the inside of sealing lip.
Beneficial effect: the present invention closely wraps in the outside of punching drilling rod by having certain flexible sealing lip, flow down along drilling rod with the fluid that prevents from producing in punch process, plays sealing of hole effect.Sealing adopts ripple struction, and has certain elasticity, therefore can, along with the swing of drilling rod and the rotation self adaptation adjustment of stretching, ensure all the time tight seal between drilling rod and sealing lip, has reached good sealing effectiveness.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Reference numeral: 1, sealing lip, 2, sealing, 3, fixed part, 4, support frame, 5, punching drilling rod.
Detailed description of the invention
As shown in Figure 1, drilling rod hole sealing device for the punching of a kind of colliery, sealing device is made up of sealing 2 and the fixed part 3 that is connected to sealing 2 surroundings, fixed part 3 is fixedly connected with drilling rod hole surrounding, described sealing 2 has continuous crest and a ripple struction of trough for what elastomeric material was made, on sealing 2, be provided with the annular seal lip 1 passing for punching drilling rod 5, the outer circumference surface of the sealing surface of sealing lip 1 and punching drilling rod 5 matches, and is provided with support frame 4 in the inside of sealing lip 1.
Described sealing device is connected to be used in conjunction with other gathering-devices by fixed part 3, and fixed part 3 can adopt flange arrangement.
On the sealing surface of described sealing lip 1, being provided with anti-wear component, can be the thing such as copper sheathing, packing.
The thickness of described sealing lip 1 is greater than the thickness of sealing 2 other parts, can increase like this sealing surface of sealing lip 1, improves the sealing area between punching drilling rod 5, good airproof performance.Sealing lip 1 is structure as a whole with the ripple struction of sealing 2.
In punch process, along with swing and the rotation of punching drilling rod 5, the ripple struction of sealing 2 can stretch with drilling rod 5, has ensured the sealing between sealing lip 1 and punching drilling rod 5.Wherein, support frame 4 plays the object that keeps sealing lip 1 shape, in the swing process of punching drilling rod 5, makes sealing lip 1 closely wrap in the outside of punching drilling rod 5.
