Description

Technical Field

[0001] This utility model is a fire prevention and emergency rescue device for coal mines, belonging to the field of coal mine facilities. Background Technology

[0002] Due to the complex underground environment of coal mines, with multiple risks such as gas, coal dust, and high temperatures, fire accidents can easily trigger secondary disasters such as explosions and poisoning / suffocation. Emergency fire prevention and rescue in coal mines must implement measures of "prevention first, combined with control." Explosion-proof water bag shelters installed in roadways are key facilities for suppressing the spread of explosion flames. These shelters are suspended by hooks from two horizontally arranged hollow tubes, with the ends of the tubes suspended from the roadway ceiling by wires. However, the roof of coal mine roadways is prone to deformation under mine pressure, resulting in a height difference between the two ends of the hollow tubes. This causes the explosion-proof water bags to slide along the hollow tubes and squeeze against each other, causing internal water to leak out. This problem not only reduces the effective volume of the explosion-proof water bags, decreasing their explosion-suppressing effect, but also requires frequent inspections and adjustments to the water bags' positions and replenishment of water, increasing labor costs and safety risks. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coal mine fire prevention and emergency rescue device to solve the problems mentioned in the background technology. This utility model reduces the impact of roadway top deformation on the state of the explosion-proof water bag, eliminates the need for frequent adjustment of the explosion-proof water bag state and replenishment of water, and reduces management costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coal mine fire prevention and emergency rescue device, comprising a hanging plate with two fixing holes on its upper surface, a shaft column directly below the hanging plate, a ring cylinder rotatably connected to one end of the shaft column, two inclined arms symmetrically mounted on the annular side of the ring cylinder, a connecting plate fixedly connected to the end of each inclined arm away from the ring cylinder, and sleeves installed at both ends of the connecting plate, one end of each sleeve being closed; multiple explosion-proof water bags arranged at equal intervals on the lower side of the shaft column, two hollow tubes connected to the explosion-proof water bags on the upper side of each water bag, the ends of the hollow tubes being inserted into the sleeves; a limiting plate fixedly connected to one end of the hanging plate; the end of the shaft column away from the ring cylinder slidingly contacting the limiting plate; a short stud rotatably mounted on the lower surface of the hanging plate near the limiting plate; a threaded hole opened at the end of the shaft column near the limiting plate, the short stud being threadedly connected to the threaded hole.

[0005] Furthermore, hooks are suspended at the upper part of the two parallel sides of the explosion-proof water bag. The hooks have an S-shaped structure, and the end of the hook away from the explosion-proof water bag is suspended on the hollow tube.

[0006] Furthermore, the lower surface of the limiting plate is provided with an insertion groove, one end of which is closed. An insertion strip is inserted into the insertion groove, and a vertical plate is fixedly connected to the end of the insertion strip outside the insertion groove. The side of the vertical plate facing the explosion-proof water bag is flush with the side of the limiting plate facing the shaft column. A support plate is installed at the lower part of the side of the vertical plate facing the explosion-proof water bag. A vertical hole is provided on the upper surface of the support plate, and a long stud is inserted into the vertical hole. A hexagonal post is installed at the upper end of the long stud. A hexagonal hole is provided at the middle of the lower surface of the short stud, and the hexagonal post is inserted into the hexagonal hole. A nut is provided on the upper side of the vertical hole and threadedly connected to the long stud. A ring is provided on the lower side of the vertical hole and is sleeved on the long stud and fixedly connected to it. A handle is inserted into the shaft hole on the lower outer surface of the long stud.

[0007] Furthermore, the cross-section of the connector strip is "T" shaped, and the cross-section of the connector groove is "T" shaped.

[0008] Furthermore, a disc head is fixedly connected to the upper end of the short stud, and a circular cover is installed on the lower surface of the hanging plate near the limiting plate. A circular hole is opened in the middle of the lower surface of the circular cover, and the upper end of the short stud passes through the circular hole. The disc head is slidably installed in the space formed by the circular cover and the hanging plate.

[0009] Furthermore, the ring cylinder is provided with blocking rings on both sides along the length direction of the shaft column, and the blocking rings are sleeved on the shaft column and connected and fixed to the shaft column.

[0010] Furthermore, a notch is provided at the end of the tilting arm away from the cylinder, and the connecting plate is installed in the notch.

[0011] The beneficial effects of this utility model are: 1. The hanging plate is installed at the top of the coal mine roadway. When the roadway top deforms, the ring cylinder will rotate around the axis column, so that the triangular structure formed by the tilting arm, connecting plate and hollow tube will rotate synchronously, so that the hollow tube always keeps the horizontal state, reducing the impact of roadway top deformation on the state of the explosion-proof water bag, eliminating the need to frequently adjust the state of the explosion-proof water bag and replenish water, thus reducing management costs.

[0012] 2. Insert the connector strip into the connector slot to connect the vertical plate and the limiting plate. Then, adjust the position of the long stud along the vertical hole so that the hexagonal stud is inserted into the hexagonal hole. Then, tighten the nut so that the distance between the nut and the ring is slightly greater than the thickness of the support plate, thus keeping the relative position of the long stud and the vertical plate unchanged. At the same time, the long stud and the short stud are assembled together. Use the handle to rotate the structure formed by the long stud and the short stud, so that the shaft moves downward along the structure formed by the long stud and the short stud. Under the interaction of the limiting plate and the vertical plate, the shaft is prevented from rotating, thereby achieving the purpose of lowering a row of explosion-proof water bags at one time. This facilitates the drainage of water from the explosion-proof water bags at a lower position, compared with the method of draining water from the explosion-proof water bags at a higher position. This avoids personnel getting wet and improves the safety of operation. Separate the long stud and the vertical plate from the short stud and the limiting plate respectively, so that the long stud and the vertical plate can be reused multiple times.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-3This utility model provides a technical solution: a coal mine fire prevention and emergency rescue device, including a hanging plate 1. Two fixing holes 2 are opened on the upper surface of the hanging plate 1. A short stud 18 is rotatably installed on the lower surface of the hanging plate 1 near the limiting plate 5. A disc head 21 is fixedly connected to the upper end of the short stud 18. A circular cover 17 is installed on the lower surface of the hanging plate 1 near the limiting plate 5. A circular hole is opened in the middle of the lower surface of the circular cover 17. The upper end of the short stud 18 passes through the circular hole, so that the disc head 21 is slidably installed in the space formed by the circular cover 17 and the hanging plate 1, thus completing the rotational connection between the short stud 18 and the hanging plate 1.

[0016] See Figures 1-3 A shaft post 15 is provided directly below the hanging plate 1. A threaded hole 20 is provided at one end of the shaft post 15 near the limiting plate 5, so that the short stud 18 is threaded into the threaded hole 20, which makes it easy for the shaft post 15 and the hanging plate 1 to maintain a constant relative position. One end of the hanging plate 1 is connected and fixed to the limiting plate 5, so that the end of the shaft post 15 away from the ring cylinder 3 slides in contact with the limiting plate 5, preventing the shaft post 15 from rotating around the short stud 18.

[0017] See Figure 1 One end of the shaft column 15 is fitted with a ring cylinder 3 that is rotatably connected to the shaft column 15. Both sides of the ring cylinder 3 along the length of the shaft column 15 are provided with blocking rings 4 that slide in contact with the ring cylinder 3. The blocking rings 4 are fitted onto the shaft column 15 and fixedly connected to it. Under the constraint of the two blocking rings 4, the relative position of the shaft column 15 and the ring cylinder 3 remains unchanged. Two inclined arms 6 are symmetrically installed on the annular side of the ring cylinder 3. A connecting plate 9 is fixedly connected to a notch at the end of the inclined arm 6 away from the ring cylinder 3. Both ends of the connecting plate 9 are fitted with sleeves 8, one end of which is closed. Multiple explosion-proof water bags 10 are arranged at equal intervals on the lower side of the shaft column 15. The explosion-proof water bag 10 has two hollow tubes 7 on its upper side that are connected to it. The ends of the hollow tubes 7 are inserted into the sleeves 8. Hooks are suspended from the upper part of the two parallel sides of the explosion-proof water bag 10. The hooks are S-shaped, with the end of the hook away from the explosion-proof water bag 10 hanging on the hollow tube 7. The hooks connect the explosion-proof water bag 10 and the hollow tubes 7, fixing the hanging plate 1 to the top of the coal mine roadway. When the top of the roadway deforms due to mine pressure, the ring cylinder 3 can rotate around the shaft column 15, driving the triangular structure composed of the tilting arm 6, connecting plate 9, and hollow tubes 7 to rotate synchronously, keeping the hollow tubes 7 in a horizontal state. This design effectively offsets the impact of roadway deformation on the explosion-proof water bag 10, preventing the explosion-proof water bag 10 from sliding and being squeezed due to the tilt of the hollow tubes 7, and causing water to overflow. It eliminates the need for personnel to frequently adjust the position of the water bag or replenish water, significantly reducing management costs.

[0018] See Figures 1-4The lower surface of the limiting plate 5 has a T-shaped insertion groove 16, one end of which is closed. A T-shaped insertion strip 23 is inserted into the groove 16. A vertical plate 14 is fixed to the outer end of the insertion strip 23. The side of the vertical plate 14 facing the explosion-proof water bag 10 is flush with the side of the limiting plate 5 facing the shaft post 15. A support plate 11 is installed at the lower part of the side of the vertical plate 14 facing the explosion-proof water bag 10. A vertical hole is formed on the upper surface of the support plate 11, and a long stud 13 is inserted into the hole. A hexagonal post 24 is installed at the upper end of the long stud 13. A hexagonal hole 19 is provided at the center of the lower surface of the stud 18. The hexagonal post 24 is inserted into the hexagonal hole 19. A nut 25 is provided on the upper side of the vertical hole, which is threaded to the long stud 13. A ring 22 is provided on the lower side of the vertical hole. The ring 22 is fitted onto the long stud 13 and is connected and fixed to the long stud 13. A handle 12 is inserted into the shaft hole provided on the lower outer surface of the long stud 13. The insertion strip 23 is inserted into the insertion slot 16 to complete the insertion and fixing of the vertical plate 14 and the limiting plate 5. Then, the position of the long stud 13 is adjusted along the vertical hole so that the hexagonal post 24 at the upper end of the long stud 13 is inserted into the hexagonal hole 19 at the bottom of the short stud 18. The nut 25 is turned until the distance between it and the ring 22 is slightly greater than the thickness of the support plate 11 to lock the relative position of the long stud 13 and the vertical plate 14, and at the same time, the long stud 13 and the short stud 18 are assembled. Rotating the long stud 13-short stud 18 assembly via handle 12 drives the shaft 15 downwards along the threaded structure. The limiting plate 5 and vertical plate 14 prevent the shaft 15 from rotating, thus simultaneously lowering the entire row of explosion-proof water bags 10 to the lowest point. This operation eliminates the need for personnel to work at heights to drain water from the water bags, avoiding the risk of getting them wet and improving safety. After the operation is completed, the long stud 13, vertical plate 14, short stud 18, and limiting plate 5 can be easily separated, allowing for component reuse.
