Problems solved by technology

[0003] However, the existing mine support devices can only support the mine, and the support device is often squeezed and deformed in the mine. If the miners fail to detect the deformation in time, it may cause collapse Accidents, so it is necessary to set up a mine fixing device for coal mines that can detect deformation in time and has a safety warning function

Embodiment 1

[0019] see Figure 1~3 , in the embodiment 1 of the present invention, a kind of coal mine mine fastening device with safety warning function, comprises base 3 and the telescopic support leg 1 that is arranged on both sides on the base 3, setting base 3 facilitates the telescopic support leg 1 of both sides 1 fixed installation, the upper support plate 2 is fixedly installed on the top of the telescopic support legs 1 on both sides, and the upper support plate 2 is used to support the top of the mine; the telescopic support leg 1 is provided with a height adjustment mechanism , this setting is convenient for adjusting the height between the upper support plate 2 and the base 3, and meets different installation requirements; a plurality of cutting knives 9 are installed on the bottom of the upper support plate 2, and a connecting rope 10 is arranged below the cutting knives 9, The connecting rope 10 is set through the guide wheel 11 and the through hole 16 on the support block ...

Embodiment 2

[0021] see Figure 1~3 , The main difference between Embodiment 2 and Embodiment 1 is that the alarm 19 is an audible and visual alarm.

[0022] The telescopic support leg 1 includes a lower rod 18 and an upper rod 17 whose lower end is slidably disposed inside the lower rod 18 .

[0023] The upper support plate 2 is fixedly mounted on the upper rod 17, and the bottom of the lower rod 18 is fixedly mounted on the base 3; the lower rod 18 is fixedly mounted with a threaded block 4, and the threaded hole on the threaded block 4 is provided with There is a self-rotating threaded rod 5, and the upper end of the self-rotating said threaded rod 5 is rotatably mounted on the upper support plate 2. The self-rotating threaded rod 5 rotates in the threaded hole on the threaded block 4 so that the threaded rod 5 stretches out or descends, thereby adjusting the height of the upper support plate 2 to meet the mine support requirements of different heights.

[0024] A worm gear 6 is fixed...

Abstract

The invention discloses a coal mine cave fixing device with a safety warning function and relates to the technical field of coal mine production equipment. The device comprises a base and telescopic supporting legs arranged on the two sides of the base, the tops of the telescopic supporting legs on the two sides are fixedly provided with upper supporting plates, and the upper supporting plates areused for supporting the top of a mine cave; and a plurality of cutting knives are installed at the bottoms of the upper supporting plates, a connecting rope is arranged below the cutting knives, theconnecting rope penetrates through a guide wheel and a through hole in a supporting block, one end of the connecting rope is fixedly installed on the telescopic supporting leg on one side, the other end of the connecting rope is fixedly connected to a moving plate, the bottom of the moving plate is fixedly provided with an elastic piece, the bottom end of the elastic piece is fixedly installed onthe supporting block, a position switch is arranged above the moving plate, and the telescopic supporting legs are further provided with warning devices electrically connected with the position switch. The device can give warning signals in time and can meet requirements of mine caves with different heights.

Description

technical field [0001] The invention relates to the technical field of coal mine production equipment, in particular to a mine hole fixing device with a safety warning function. Background technique [0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. Most coal mines are underground coal mines. When the coal seam is far away from the surface, they generally choose to dig underground roadways to mine coal. This is an underground coal mine. Underground coal mines need to support the mine when working. [0003] However, the existing mine support devices can only support the mine, and the support device is often squeezed and deformed in the mine. If the miners fail to detect the deformation in time, it may cause collapse Therefore, it is necessary to set up a mine fixing device for coal mines with a safety warning function that can detect deformation in time. Contents of the invention [0004] The object of the present invention is to ...
