Description
Technical Field
The utility model belongs to the technical field of colliery is mining dryer end ring in pit connects sealedly.
Background
The ventilation system is one of important systems for underground safety production of coal mines, and mainly provides oxygen for workers and dilutes underground harmful gas. For some tunnel excavation working faces, a local fan and an air cylinder are needed to supply air to a tunneling working face place, and the local fan is used for guiding fresh air flow in a main tunnel to the working place through the air cylinder. Because the tunnel is longer, need connect one section with the dryer and guarantee that the link does not take place to leak gas at this in-process. The existing air duct sections are provided with circular end rings at two ends, and when the air duct sections are connected, the end ring of one air duct section extends into the end ring of the other air duct section to be stretched and straightened, so that the left end ring and the right end ring are overlapped and gathered together, and are connected one section by one section in sequence to form an integral air duct with a certain length. In practical use, due to the influence of factors such as wind vibration in ventilation work, the two end rings are sometimes staggered to form a gap to cause a small air leakage phenomenon, and for the purpose of preventing air leakage, iron wires are often reused to reinforce and bind the two end rings to complete the fixed mutual tight connection between the end rings of the air duct, so that the sealing is further strengthened to prevent the small air leakage problem. The connection structure mode has the advantages that on one hand, the end ring has larger diameter and is not easy to operate in binding, so that the working efficiency of connection of the air duct section is low; on the other hand, sometimes the reserved iron wire head often punctures the dryer, causes new air leakage problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an easy operation, efficiency are higher, safe and reliable's sealed card is connected to mining dryer end circle.
In order to realize the above purpose, the utility model discloses a: the groove-shaped clamping seat, the arc-shaped fixing clamp, the arc-shaped movable clamp and the fastening jackscrew are fixedly arranged on the left side inside the groove-shaped clamping seat, the arc-shaped movable clamp and the fastening jackscrew are sequentially arranged on the right side inside the groove-shaped clamping seat, and the fastening jackscrew penetrates through the right wall of the groove-shaped clamping seat to prop against the arc-shaped movable clamp.
The arc-shaped fixing clip is a semicircular arc-shaped fixing clip.
The arc-shaped movable clamp is a semicircular arc-shaped movable clamp.
The fastening jackscrew is an internal hexagonal jackscrew.
Thus, when the wind barrel sections are connected, the end ring of one wind barrel section is inserted into the end ring of the other wind barrel section to be stretched and straightened, so that the left end ring and the right end ring are overlapped and closed, then the fastening jackscrew of the utility model is loosened, the arc-shaped fixing clip and the arc-shaped movable clip are clipped on the left end ring and the right end ring, the fastening jackscrew is adjusted to lead the arc-shaped movable clip to gradually move leftwards to extrude the end ring, finally the two end rings are firmly clipped between the arc-shaped fixing clip and the arc-shaped movable clip, the four wind barrel end rings can be used, the upper, the lower, the left and the right positions of the wind barrel end rings are respectively fixedly connected, the problems of dislocation and the like can not occur during the work, the operation is relatively simple and convenient, the wind barrel connecting and mounting efficiency is improved, the labor intensity of workers is reduced, the sealing performance of the end rings is further improved, and the problems of wind barrel cloth puncture and air leakage and, has the characteristics of simple use and operation, higher efficiency, safety, reliability and the like.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As can be seen from fig. 1 and 2, the present invention includes: the clamping device comprises a groove-shaped clamping seat 1, an arc-shaped fixing clamp 2, an arc-shaped movable clamp 5 and a fastening jackscrew 6. An arc-shaped fixing clip 2 is fixedly arranged on the left side inside the groove-shaped clamping seat 1, and the arc-shaped fixing clip can be fixed on the left side wall inside the groove-shaped clamping seat in a welding or casting mode, so that firmness and reliability are guaranteed. An arc-shaped movable clamp 5 and a fastening jackscrew 6 are sequentially arranged on the right side in the groove-shaped clamp seat, and the fastening jackscrew penetrates through the right wall of the groove-shaped clamp seat to prop against the arc-shaped movable clamp 5. The arc fixing clip can be a semicircular arc fixing clip so as to enable the arc fixing clip to be consistent with the shape radian of the left end ring 3, and the arc fixing clip is matched with the left end ring in a fixed connection mode, so that the arc fixing clip is safer and more reliable. The arc-shaped movable clamp is a semicircular arc-shaped movable clamp so as to be consistent with the shape radian of the right end ring 4, and the arc-shaped movable clamp is matched with the right end ring in fixed connection, so that the movable clamp is safer and more reliable. The fastening jackscrew can adopt an inner hexagonal jackscrew, and after the fastening jackscrew is fixedly connected, the outer end of the fastening jackscrew does not have any extra step and cannot influence the air duct. The length of the arc-shaped fixing clip and the length of the arc-shaped movable clip are set to be about 5cm, and the lengths of the arc-shaped fixing clip and the arc-shaped movable clip are the same, so that the two sides of the left end ring and the right end ring are clamped conveniently. All parts are made of corrosion-resistant, antistatic and anti-combustion materials so as to meet the standard regulation of the working environment in the underground coal mine. The utility model discloses a series of products can be made according to the specification of dryer to the specification size.
