Description

Technical Field

[0001] The utility model relates to the technical field of air doors in mines, in particular to an air door wall with an adjusting structure. Background Art

[0002] The damper is an indispensable ventilation structure in the mine ventilation network. Its main function is to cut off the wind flow and create conditions for the on-demand distribution of the mine wind flow. At the same time, it provides convenience for pedestrians and transportation. The belt passing through the damper wall is a very common phenomenon in mine production. When the belt conveyor passes through the damper, due to its large cross-section, there will inevitably be a large air leakage, which affects the safety of underground ventilation.

[0003] At present, in the prior art, a Chinese patent with announcement number CN213392235U discloses a belt conveyor passing through a damper device, which solves the technical problem that when the coal mine belt transportation system in the prior art passes through the damper, a large hole is often chiseled on the damper wall, destroying the sealing of the damper, and the wind flows through the hole, which greatly reduces the effect of the damper and causes difficulties in effective ventilation of the mine. However, during the use of the device, since the movable door will rotate when in use, after the rotation, the opening range of the movable door is large, so that the air leakage problem still needs to be improved. In view of this, we propose a damper wall with an adjustment structure. Utility Model Content

A through groove 103 is opened on the upper outer wall of the frame 1. Through the use of the through groove 103, the windshield 21 can be not affected when it is lifted or lowered. An upper windshield device 2 is arranged on the frame 1. Through the use of the upper windshield device 2, the height of the windshield 21 can be adjusted according to the material when the belt is conveying the material, and the electric telescopic plate 22 can be adjusted to shrink at the same time, so as to minimize the gap for air leakage and improve the windshield effect. The upper windshield device 2 includes a windshield 21, and the windshield 21 is slidably connected to the inner wall of the frame 1, and the inner wall of the windshield 21 The upper sliding part is connected with an electric telescopic plate 22, and the outer wall of the wind shield 21 is fixedly connected with a threaded block 23. The threaded block 23 is penetrated by a screw rod 24 and is threadedly connected with the screw rod 24. By using the threaded block 23, when the screw rod 24 rotates, the threaded block 23 can drive the wind shield 21 to slide stably under the effect of the wind shield 21 being limited. A lower wind shield mechanism 1 3 and a lower wind shield mechanism 2 4 are arranged under the upper wind shield device 2. By using the lower wind shield mechanism 1 3 and the lower wind shield mechanism 2 4, gaps can be prevented from being generated during the lower belt transmission.

The outer wall of the upper wind shield device 2 is detachably connected with a wind shield strip 5, and the inner wall of the frame 1 is fixedly connected with a blocking block 6.

[0030] In an embodiment of the utility model, in order to be able to adjust the height of the wind shield 21, specifically, the screw 24 passes through the wind shield 21 and is slidably connected to the wind shield 21, and the end of the screw 24 away from the wind shield 21 is fixedly connected to the output shaft of the motor 25, and the motor 25 is fixedly installed on the top of the mounting frame 26, and the bottom of the mounting frame 26 is fixedly connected to the outer wall of the frame body 1. The output shaft of the motor 25 rotates, driving the screw 24 to rotate, and then under the effect of the wind shield 21 being limited, the threaded block 23 is driven to rise and fall, thereby adjusting the height of the wind shield 21, so that the staff can adjust the height of the wind shield 21 according to the goods transported on the belt. At the same time, the electric telescopic plate 22 can be further telescopically adjusted on the wind shield 21 to improve the windshield effect.
