Description

Technical Field

[0001] The utility model belongs to the technical field of rescue devices, in particular to a roof fall rescue device in an underground coal mine. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. During underground mining in coal mines, there is often a risk of collapse, so rescue equipment is needed. Existing rescue equipment cannot support the top of the mine well when in use. Therefore, when rescuers dig holes at the collapsed area, it is easy to cause secondary collapse, which cannot well ensure the life safety of the rescuers.

[0003] In the prior art, a Chinese patent with a reference publication number of CN 214273694 U discloses a coal mine roof fall rescue device, including a base, vertical plates are arranged at the four corners of the bottom of the base, rollers are arranged on the rear end faces of the vertical plates, and the four groups of the vertical plates are rotatably connected to the respective matching rollers through a rotating shaft, side plates are arranged on the left and right sides of the top of the vertical plates, a height adjustment device is arranged between the two groups of the side plates, and a support assembly is connected to the top of the height adjustment device. The utility model can well support the top of the mine cave, and when the rescue personnel are digging a hole at the collapsed area, it can effectively prevent the mine from a secondary collapse, thereby ensuring the life safety of the rescue personnel.

[0004] The comparative document provides a coal mine roof fall rescue device, but when the above patent is used to support and rescue one side of a roof fall in a coal mine, the rescue position is narrow, and when the roof falls, the rescue workers need to repeatedly pass through the device and move out, which is time-consuming and labor-intensive, and greatly reduces the efficiency of the rescue. It is also difficult to achieve comprehensive protection on the side of the rescue position, which can easily cause the rescue workers to be hit by falling rocks and get injured.

[0005] Therefore, a coal mine roof fall rescue device is proposed. Utility Model Content

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides a roof fall rescue device for underground coal mines, such as Figure 1-4As shown, it includes a base 1, the top of the base 1 is fixedly connected to a hydraulic cylinder 2 by bolts, a total of six hydraulic cylinders 2 are provided, and the six hydraulic cylinders 2 are symmetrically arranged on the top of the base 1, the hydraulic cylinder 2 is fixedly connected to a top supporting plate 3 through its output end, the outer side wall of the top supporting plate 3 is integrally cast with an upper side plate 41 in the side block assembly 4, the top of the base 1 is fixedly connected to a lower side plate 42 by bolts, the top of the lower side plate 42 is provided with a guide hole 43, the bottom of the upper side plate 41 is welded with a side column 44, and an operating groove 5 is provided at the central position of the outer wall of one side of the base 1, and the cross section of the operating groove 5 is a rectangular structure The base 1 has a structure in which a conveying platform 6 is fixedly connected to the top center of the base 1 by bolts, a roller 7 is rotatably connected to the top of the conveying platform 6, an arc groove for rotation is provided at the top of the conveying platform 6 near the outer side of the roller 7, a concave hole 8 is provided at the bottom of the base 1, and there are six concave holes 8 in total, and the six concave holes 8 are symmetrically arranged at the bottom of the base 1, a telescopic rod 9 is welded to the inner top of the concave hole 8, and a support frame 10 is rotatably connected to the bottom end of the telescopic rod 9, a spring 11 is provided between the top of the support frame 10 and the inner top of the concave hole 8, and a walking wheel 12 is rotatably connected to the inner wall of one side of the support frame 10.

[0024] It should be noted that, because the existing coal mine roof fall rescue device is used to support and rescue one side of the coal mine roof fall, the rescue position is narrow, and when the roof falls, the rescue personnel need to repeatedly pass through the device and move out, which is time-consuming and labor-intensive, and greatly reduces the efficiency of the rescue. It is also difficult to achieve comprehensive protection on the side of the rescue position, which makes it easy for the rescue personnel to be hit by falling rocks and injured. The present embodiment can provide a relatively spacious space for the rescue personnel to clean the fallen rocks at the roof fall through the arrangement of the operating groove 5 and the conveying platform 6, so as to facilitate the rescue operation. The rotating rollers 7 on the conveying platform 6 can easily push the stones, and can quickly, conveniently and labor-savingly clean the stones away from the collapsed area, thereby improving the cleaning speed and facilitating the implementation of rapid rescue. A side protection structure for the rescue personnel is formed by a plurality of side columns 44 to prevent the falling rocks caused by the collapse and roof fall from falling and impacting the hydraulic cylinder 2 or the rescue personnel.

[0025] Specifically, in the present embodiment, the present scheme mainly comprises a side stopper assembly 4, an operating groove 5 and a conveying platform 6. When in use, the base 1 is pushed and moved to one side of a collapsed or roof-falling part in the coal mine by the rotation of the walking wheel 12. At this time, the hydraulic cylinder 2 is controlled to work, and the hydraulic cylinder 2 drives the top supporting plate 3 to move upward through its output end. The top supporting plate 3 contacts the inner top of the coal mine shaft during the upward movement, and supports one side of the collapsed or roof-falling part of the coal mine shaft through the top supporting plate 3 to prevent the coal mine shaft from collapsing again and causing injuries to rescuers. With the support of the top supporting plate 3, the base 1 is subjected to a reverse extrusion force, and the base 1 moves toward the inner bottom of the coal mine shaft passage. After being compressed, the walking wheel 12 moves into the concave hole 8, and the deformation of the telescopic rod 9 and the spring 11 is realized. The ability allows the walking wheel 12 to be completely received inside the recessed hole 8. When the top supporting plate 3 moves upward, the side column 44 at the bottom of the top supporting plate 3 moves upward synchronously, and under the guide limit of the guide hole 43, the side column 44 can move stably. A plurality of side columns 44 form a side protection structure for rescue personnel to prevent falling rocks from collapse and roof fall from falling and impacting the hydraulic cylinder 2 or rescue personnel. After completing the support on one side of the collapse in the coal mine, the rescue personnel stand on the inner side of the operating groove 5, and when clearing the falling rocks blocking the collapse, the stones are moved to the roller 7 on the conveying platform 6. Through the rotation of the roller 7, the stones can be easily pushed, and the stones can be quickly, conveniently and labor-savingly cleared away from the collapse, thereby increasing the cleaning speed and facilitating rapid rescue.

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, the bottom end of the side column 44 is inserted into the guide hole 43.

[0027] In this embodiment, the moving track of the side column 44 can be limited by the guide hole 43, so that the side column 44 can be pulled out or retracted into the guide hole 43 at the top of the lower side plate 42 as the upper side plate 41 is raised or lowered.

[0028] In a further preferred embodiment of the present invention, Figure 4 As shown, the running wheel 12 can be completely received in the recessed hole 8 after being pressed.

[0029] In this embodiment, the base 1 can be made to contact the bottom of the coal mine passage to achieve more stable and firm support, ensuring that the top supporting plate 3 provides better support to the top of the coal mine passage.
