Description

Technical Field

[0001] The utility model relates to the technical field of headwind prevention devices, in particular to a headwind prevention device for a belt conveyor air door wall. Background Art

[0002] Due to the influence of various factors, the belt conveyor in the coal mine often experiences reverse flow of wind direction and gas shock wave, which not only affects the safety of the belt conveyor and personnel, increases maintenance costs, but also affects the efficiency of the entire production process. Therefore, in order to solve this problem, a belt air door anti-backflow device is installed in the belt conveyor lane in the coal mine, which can control the wind and prevent backflow. The existing belt air door anti-backflow device needs to be manually controlled in real time according to the on-site situation, and cannot automatically control air leakage and prevent backflow accidents.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A belt conveyor wind gate wall anti-wind device comprises an upper frame and a lower frame, a bracket is installed on the top of the front side of the upper frame, a strut is installed on the end of the bracket, a windward plate is rotatably installed on the strut, a suspension rod is provided below the windward plate, the front side of the upper frame is composed of a front baffle and an upper baffle, the front baffle is rotatably installed on the upper frame, the lower end of the front baffle is matched with the upper end structure of the upper baffle, a lifting ring is provided on the front baffle, the front baffle is rotated to 90°, and the lifting ring drives the front baffle to hang on the suspension rod, and a lower adjustment plate is provided on the front side of the lower frame, and a rubber windshield curtain is fixedly connected to the lower adjustment plate.

[0006] Furthermore, a rear baffle is rotatably mounted on the back of the upper frame.

[0007] Furthermore, a rubber windshield curtain is provided at the lower part of the front baffle.

[0008] Furthermore, the upper frame and the lower frame are detachably connected.

[0009] Furthermore, both ends of the upper baffle are adjustably mounted on the upper frame.

[0010] Furthermore, both ends of the lower adjustment plate are adjustably mounted on the lower frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model is easy to install, low in cost, can effectively solve the problem of continuous transportation of the belt passing through the wind gate wall, and can make the belt conveyor carry out normal transportation when passing through the wind gate wall underground. When there is a headwind impact phenomenon, the rotatably installed headwind plate moves backward along the wind direction trajectory, and the front baffle plate hanging on the headwind plate through the lifting ring quickly falls and closes to make the belt conveyor belt passing through the wind gate wall play a headwind-proof and airtight effect, and the lower frame windproof wall and the lower belt surface windproof wall of the belt conveyor are windproof on both sides of the front and rear sides;

[0012] The opening direction of the rear baffle is consistent with the coal conveying direction of the belt conveyor, and the opening size can be automatically adjusted and sealed according to the size of the material;

[0013] When the headwind phenomenon causes the front baffle to fall and close, the rubber windshield curtain at the bottom of the front baffle can not only achieve a sealing effect, but also does not affect the transportation of the entire material because the rubber windshield curtain is made of flexible material;

[0014] The opening and closing state of the device can be linked with the belt, achieving automatic control of air leakage and backflow prevention. When an accident occurs, it can effectively prevent the reversal of wind flow caused by coal and gas outbursts, improve the safety of construction in the anti-outburst area, and reduce the disaster-affected area when the gas outburst occurs. It can meet the operation of belt conveyors under medium and heavy loads, without dangerous factors such as electrical sparks, and the operation is safe and reliable. At the same time, the underground air source is more convenient and safe, and the labor intensity of construction personnel is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
