Description

Technical Field

[0001] The utility model relates to the technical field of coal mine escape, in particular to a high-strength coal mine escape device. Background Art

[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. Coal mines may collapse during mining, and safety escape devices need to be prepared in advance.

[0003] When a collapse occurs inside a coal mine, a lot of rubble will fall downward. General emergency escape devices can only provide a certain amount of protection space for workers in the mine. When rubble falls from the top of the escape device, it is easy to create a hole in the top of the device, causing the fallen rocks to stay and accumulate on the top of the device. A large amount of fallen rocks will cause the device to deform, posing a certain potential danger to the workers taking shelter inside the device.

[0004] Therefore, we propose a high-strength coal mine escape device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model provides a high-strength coal mine escape device, which solves the problem mentioned in the above background technology that when a collapse occurs inside a coal mine, a large amount of rubble will fall downward, and a general emergency escape device can only provide a certain protection space for the workers in the mine. When rubble falls from the upper end of the escape device, it is easy to smash a hole in the upper end of the device so that the fallen rocks stay and accumulate on the upper end of the device. A large amount of fallen rocks will cause the device to deform, posing a certain potential danger to the workers taking shelter inside the device.

[0006] The utility model provides the following technical solutions: a high-strength coal mine escape device, comprising an escape cabin, an anti-rockfall assembly installed at the upper end of the escape cabin, the anti-rockfall assembly comprising a fixed plate fixedly installed at the upper end of the escape cabin, two adjacent vertical plates fixedly installed at the middle of the upper end of the fixed plate, each of the vertical plates is provided with an opening, each of the openings is rotatably connected with a rotating rod, rubber plates are commonly fixedly installed at both ends of the rotating rod, and a spring is commonly fixedly installed between the lower wall of the rubber plate and the upper wall of the fixed plate.

[0007] As an optional solution described in the utility model, a telescopic plate is fixedly installed between the lower wall of the rubber plate and the upper wall of the fixed plate, a C-shaped rubber connecting block is fixedly installed between the side walls of the two vertical plates, and the C-shaped rubber connecting block is located directly above the two vertical plates.

[0012] The utility model has the following beneficial effects:

[0013] 1. When a collapse occurs in a coal mine, workers can hide in the escape cabin. When rubble falls from the upper end of the escape cabin, the rubble falls onto the rubber plate at the upper end of the escape cabin. Under the action of the weight of the falling rocks, the rubber plate drives the rotating rod to rotate along the opening in the vertical plate. The center of gravity of the falling rocks on the inclined rubber plate shifts, and the falling rocks slide down along the inclined angle to the side of the escape cabin. After the falling rocks on the rubber plate automatically slide down, the rubber plate is automatically lifted and rotated to the initial position under the action of spring 1. When there are falling rocks from above, this high-strength coal mine escape device can have a certain buffering effect on the falling rocks, and can rely on the weight of the falling rocks to rotate the rubber plate. When the rubber plate rotates due to the falling rocks, it can automatically clean up the falling rocks on its upper end, and automatically return to its original position after cleaning. It is safe and practical.

[0014] 2. With the cooperation between the C-shaped rubber connecting block, the shell, the storage box, the bellows, the second spring, the pull ring, the fixed rod, the movable rod and the L-shaped fixed block, the device can provide a protective space for the workers when a collapse occurs in the coal mine, and is provided with a storage box that can be stored, which can provide emergency supplies to the workers without affecting the size of the activity space.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0021] See also Figure 1 - Figure 3 A high-strength coal mine escape device includes an escape cabin 1, and an anti-falling rock assembly 2 is installed at the upper end of the escape cabin 1. The anti-falling rock assembly 2 includes a fixed plate 21 fixedly installed at the upper end of the escape cabin 1, and two adjacent vertical plates 22 are fixedly installed in the middle of the upper end of the fixed plate 21. The vertical plates 22 are each provided with an opening 23, and the openings 23 are each rotatably connected with a rotating rod 24. Rubber plates 25 are commonly fixedly installed at both ends of the rotating rod 24, and a spring 26 is commonly fixedly installed between the lower wall of the rubber plate 25 and the upper wall of the fixed plate 21.

[0022] When a collapse accident occurs during mining in a coal mine, workers working in the mine can hide in the escape cabin 1. When broken stones fall from the upper end of the escape cabin 1, the broken stones fall onto the rubber plate 25 at the upper end of the escape cabin 1. Since the rubber plate 25 is made of rubber, it has a certain buffering effect when the falling stones fall and hit the rubber plate 25, and the rubber plate 25 will not be permanently deformed. Since the rubber plate 25 is rotatable, under the action of the weight of the falling stones, the rubber plate 25 drives the rotating rod 24 to rotate along the opening 23 in the vertical plate 22, and the falling stones fall on the inclined rubber plate 25. The center of gravity on the plate 25 is shifted, and it slides down along the inclined angle to the side of the escape cabin 1. When the fallen rocks on the rubber plate 25 automatically slide down, the rubber plate 25 is automatically lifted and rotated to the initial position under the action of the spring 1 26. When there are fallen rocks from above, the high-strength coal mine escape device can have a certain buffering effect on the fallen rocks, and can rely on the weight of the fallen rocks to make the rubber plate 25 rotate. When the rubber plate 25 rotates due to the fallen rocks, the fallen rocks on its upper end can be automatically cleaned up, and it automatically returns to its original position after cleaning, which is safe and practical. Embodiment 2

[0023] See also Figure 2 - Figure 4 A telescopic plate 27 is fixedly installed between the lower wall of the rubber plate 25 and the upper wall of the fixed plate 21, and a C-shaped rubber connecting block 28 is fixedly installed between the side walls of the two vertical plates 22. The C-shaped rubber connecting block 28 is located directly above the two vertical plates 22. With the cooperation between the rubber plate 25, the fixed plate 21, the telescopic plate 27, the vertical plate 22 and the C-shaped rubber connecting block 28, the C-shaped rubber connecting block 28 can protect the upper end of the vertical plate 22.

[0024] Emergency components 3 are installed on both sides of the fixed plate 21. The emergency components 3 include shells 31 fixedly installed on both sides of the fixed plate 21. Storage boxes 32 are slidably connected in the two shells 31. With the cooperation between the fixed plate 21, the shells 31 and the storage boxes 32, some emergency supplies can be stored in the storage boxes 32 in advance, which can provide help when a mining accident occurs.

[0025] A bellows 33 is fixedly installed between the side walls on both sides of the storage box 32 and the lower inner wall of the shell 31, and a spring 2 34 is fixedly installed between the lower walls on both sides of the storage box 32 and the lower inner wall of the shell 31. The bellows 33 is sleeved on the outside of the spring 2 34. With the cooperation between the storage box 32, the shell 31, the bellows 33 and the spring 2 34, the connection between the storage box 32 and the shell 31 is completed through the bellows 33 and the spring 2 34.

[0026] A pull ring 35 is fixedly installed at the lower end of the storage box 32, and fixed rods 36 are fixedly installed on both sides of the lower end of the storage box 32. The two fixed rods 36 are rotatably connected to movable rods 37. With the cooperation between the storage box 32, the pull ring 35, the fixed rods 36 and the movable rods 37, the storage box 32 can be pulled downward from the shell 31 through the pull ring 35.

[0027] A plurality of L-shaped fixing blocks 38 are installed at the lower end of the fixing plate 21, and the movable rod 37 can be slidably connected to the recess of the L-shaped fixing block 38. With the cooperation between the fixing plate 21, the L-shaped fixing block 38 and the movable rod 37, the storage box 32 can be fixed by the movable rod 37 and the L-shaped fixing block 38.

[0028] When a collapse accident occurs in a coal mine, workers can enter the escape cabin 1 to avoid falling rocks. When the falling rocks hit the rubber plate 25 at the upper end to rotate, the telescopic plate 27 will also be driven to contract. The telescopic plate 27 can provide protection for the spring 26 at the lower end of the rubber plate 25. When the falling rocks hit the upper end of the vertical plate 22, the C-shaped rubber connecting block 28 can prevent the falling rocks from directly hitting the vertical plate 22, thereby providing protection for the vertical plate 22. When the workers are taking shelter in the escape cabin 1, the movable rods 37 on both sides can be rotated and slid along the fixed rods 36 to disengage from the L-shaped fixed rods. When the pull ring 35 is pulled out of the shell 31, the bellows 33 and the spring 34 are stretched. At this time, the emergency supplies in the storage box 32 can be taken out for use. After use, the storage box 32 can be pushed into the shell 31 again, and the movable rod 37 can be rotated to the L-shaped fixing block 38 to complete the fixation of the storage box 32. When a collapse occurs in a coal mine, the device can provide a protective space for workers, and is provided with a storage box 32 that can be stored, which can provide emergency supplies to workers without affecting the size of the activity space.
