Description

Technical Field

[0001] This utility model relates to the field of mine rescue technology, and more specifically, to a mine emergency rescue device. Background Technology

[0002] Underground mining environments, such as coal mines and metal mines, are complex, with confined spaces, limited ventilation, and the presence of flammable and explosive materials such as gas and coal dust. Once a fire breaks out, it spreads rapidly, and smoke accumulates significantly, easily causing major casualties and property damage. Therefore, the proper deployment of emergency rescue devices inside mines, especially those capable of rapid response and effective firefighting, is of great importance for improving the inherent safety level of mines.

[0003] For example, the specification of the “Emergency Rescue Device for Mining” disclosed in Chinese Utility Model Patent (Publication No.: CN220134008U) states that: by filling the launching tube with fire extinguishing bombs that can be broken into pieces to extinguish fire, the mechanical lock hook can be unlocked by pulling the rope, so that the fire extinguishing bombs can be thrown and broken into pieces to achieve the effect of local fire extinguishing. The device has complete functions and strong practicality. Regarding the aforementioned technologies, this device has several shortcomings. In actual use, the launch tube, consisting of front and rear annular plates and a column, forms an open structure lacking effective protection. Mine dust and moisture can easily penetrate, causing the fire extinguishing bomb to stick to the surface, increasing sliding resistance, and even jamming inside the tube. Simultaneously, the rotating parts of the mechanical locking hook are prone to sluggish movement or jamming due to corrosion or embedded particles, severely affecting triggering reliability. Furthermore, the device relies entirely on manual rope operation, making it unable to be activated promptly in unattended situations or when personnel are disabled due to smoke poisoning or emergency evacuation, resulting in a significant response blind spot and potentially missing crucial firefighting opportunities.

[0004] Therefore, we have made improvements to this and proposed a mine emergency rescue device. Utility Model Content

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1 Please refer to Figures 1-5 A mine emergency rescue device includes a protective shell 1, an arc-shaped launch plate 9 is arranged at the lower part of the interior of the protective shell 1, and symmetrically distributed rotating shafts 10 are fixedly installed on the outer wall of the front end of the arc-shaped launch plate 9. The end of the rotating shaft 10 away from the arc-shaped launch plate 9 is rotatably connected to the inner wall of the protective shell 1. A lead screw 11 is rotatably mounted on the front side of the upper part of the protective housing 1, and a winding shaft 16 is rotatably mounted on the rear side of the upper part of the protective housing 1. A transmission mechanism 13 is provided between the winding shaft 16 and the lead screw 11. An adjusting block 19 is sleeved on the outer wall of the lead screw 11. A first sealing cover plate 2 is fixedly mounted on the front side of the adjusting block 19. The first sealing cover plate 2 slides in contact with the front end of the protective housing 1. A connecting block 20 is fixedly installed at the rear end of the arc-shaped launch plate 9. A winding frame 15 is fixedly installed on the outer wall of the winding shaft 16. A pull rope 14 is arranged around the winding frame 15. One end of the pull rope 14 is fixedly connected to the connecting block 20. A drive mechanism is provided at the front of one side of the outer surface of the protective shell 1. A feeding assembly and a fixing assembly are provided on the top of the protective shell 1.

[0023] Furthermore, the fixing components include hanging columns 3 welded to the four corners of the top of the protective housing 1, with connecting frames 4 fixedly installed at the top of the hanging columns 3. This achieves reliable suspension installation of the device to the mine tunnel roof.

[0024] Furthermore, slide rails 17 are provided at the top and bottom of the front end of the protective housing 1, and sliding plates 18 are fixedly installed at the top and bottom of the back of the first sealing cover 2. The sliding plates 18 are slidably installed on the slide rails 17. This achieves a smooth sliding fit between the first sealing cover 2 and the protective housing 1.

[0025] Furthermore, the adjusting block 19 has a threaded hole that matches the lead screw 11, and the adjusting block 19 is threadedly connected to the lead screw 11 through the threaded hole. This enables the adjusting block 19 to move smoothly along the axial direction of the lead screw 11 when the lead screw 11 rotates, thereby driving the first sealing cover plate 2 to slide open or close synchronously.

[0026] Furthermore, the drive mechanism includes a servo motor 12 fixedly mounted on the front side of one side of the outer surface of the protective housing 1. The drive end of the servo motor 12 penetrates through the protective housing 1 and extends into the interior of the protective housing 1. The drive end of the servo motor 12 is fixedly connected to one end of the lead screw 11. This enables electric triggering of the device.

[0027] Furthermore, a protective cover 8 is fixedly installed on the front of one side of the outer surface of the protective housing 1, and the servo motor 12 is located inside the protective cover 8. A heat dissipation window is provided on the outer surface of the protective cover 8. This effectively prevents damage to the servo motor 12 caused by dust and impacts in the mine. At the same time, the heat dissipation window on the outer side of the protective cover 8 ensures the heat dissipation requirements of the servo motor 12 during long-term standby or operation, extends the service life of the equipment, and improves the operational stability and reliability of the device in harsh mine environments.

[0028] Furthermore, the transmission mechanism 13 consists of a driving wheel, a driven wheel, and a belt. The driving wheel and the driven wheel are connected by a belt drive. The driving wheel is fixedly installed on the outer wall of one end of the lead screw 11, and the driven wheel is fixedly installed on the outer wall of one end of the take-up shaft 16. This achieves synchronous linkage between the lead screw 11 and the take-up shaft 16.

[0029] Example 2 The mine emergency rescue device provided in Embodiment 1 is further optimized. Specifically, the feeding assembly includes a loading port 7 opened at the top of the protective housing 1, a support 5 fixedly installed on the rear side of the top of the protective housing 1, a second sealing cover 6 rotatably installed on the support 5, and a locking buckle provided at the connection between the front end of the second sealing cover 6 and the front side of the top of the protective housing 1. This enables rapid loading operations while maintaining the overall sealing and dustproof performance of the protective housing 1.

[0030] The usage process of the mine emergency rescue device provided by this utility model is as follows: In use, the entire device is fixed to the mine roof via the hanging columns 3 and connecting frames 4 at the four corners of the top of the protective housing 1. Initially, the pull rope 14 is loose, and the arc-shaped launch plate 9, hinged by the pivot 10, naturally tilts downwards under gravity at its rear end. After the operator loads the fire extinguishing bomb through the loading port 7, the bomb falls onto the arc-shaped launch plate 9 and automatically rolls backwards under its own weight, eventually stabilizing at the rear end of the arc-shaped launch plate 9. The front end of the protective housing 1 is sealed by the first sealing cover 2. When a fire occurs and fire extinguishing bombs need to be thrown, the drive mechanism, i.e., the servo motor 12, drives the lead screw 11 to rotate. The lead screw 11 drives the adjusting block 19 and the first sealing cover plate 2 fixed thereto to slide to one side along the slide rail 17 and the slide plate 18, opening the front outlet of the protective shell 1. At the same time, the lead screw 11 drives the winding shaft 16 and the winding frame 15 to rotate synchronously through the transmission mechanism 13, gradually winding and tightening the loose pull rope 14. The pull rope 14 pulls the rear end of the arc-shaped launching plate 9 upward through the connecting block 20, so that the arc-shaped launching plate 9 gradually changes from the rear end tilting posture to the rear end lifting posture, thereby pushing the fire extinguishing bomb held at the rear end forward and throwing it out from the front outlet of the protective shell 1, completing the automatic throwing of the fire extinguishing bomb. The enclosed protective shell 1 and the first sealing cover 2 completely isolate the dust and moisture in the mine, avoiding the problems of fire extinguishing bombs sticking and locking hooks getting stuck; at the same time, the electronic control automatic triggering method driven by the servo motor 12 replaces the pure manual rope pulling operation, eliminating the response blind spot in the case of no one on duty or personnel incapacitated, ensuring that the device can reliably activate and throw fire extinguishing bombs when a fire occurs.
