Description

Technical Field

[0001] The utility model relates to the technical field of mine life-saving, in particular to a mine mining safety life-saving device. Background Art

[0002] Mining safety and life-saving devices are key equipment designed to ensure the safety of miners in dangerous environments. As the depth and complexity of mining increase, the safety challenges faced by miners are also increasing. Therefore, the development and application of safety and life-saving devices have become one of the important directions of mine management and technical research. Safety and life-saving devices include various advanced technologies and equipment, such as respirators, life-saving ropes, safety helmets, protective clothing, etc. These devices not only help miners escape from dangerous areas in emergencies, but also provide key life support and protection functions.

[0003] The publication number is CN219431884U, and the Chinese patent discloses a mine safety life-saving device, which includes a life-saving capsule, the bottom of which is fixedly connected to a bottom plate, and the four corners of the lower surface of the bottom plate are fixedly connected to guide rods, and there are four guide rods, and the outer walls of the four guide rods are all sleeved with guide sleeves, and the bottom ends of the guide sleeves are fixedly connected to a base. The utility model provides a mine safety life-saving device, which can be adjusted in height by a small amplitude, so that the life-saving capsule can be kept away from the bottom surface to avoid encountering mud and rocks and various unknown liquids inside the mine, thereby improving the safety of the life-saving device.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, in order to achieve the height adjustment effect of the lifeboat, it is necessary to manually rotate the two turntables at the same time to make the two screws rotate synchronously to achieve the effect of stable ascent of the lifeboat. This complex manual adjustment not only requires more operating steps, but also may increase the risk of operating errors, thereby affecting the timeliness and effectiveness of the rescue operation. Therefore, it is necessary to provide a mining safety and life-saving device to solve the above-mentioned technical problems. Utility Model Content

[0028] See also Figure 1-4 , an embodiment provided by the utility model:

[0029] A mining safety and life-saving device, comprising:

[0030] A fixed seat 1, both sides of the top of the fixed seat 1 are fixedly installed with symmetrically distributed telescopic rods 5, the telescopic ends of the telescopic rods 5 are fixedly installed with the cabin 2, the front and rear sides of the top of the fixed seat 1 are provided with limit grooves 10, the insides of the two limit grooves 10 are rotatably installed with threaded rods 9, and the outer wall of the threaded rod 9 is provided with two groups of symmetrically distributed left-handed threads and right-handed threads. The setting of the telescopic rods 5 can improve the stability of the cabin 2 during the vertical movement process;

[0031] Two groups of symmetrically distributed adjustment blocks 11 are sleeved on the outer wall of the threaded rod 9, and the adjustment blocks 11 are slidably connected to the limit grooves 10. The top of the adjustment block 11 is hinged with a support arm 8, and one end of the support arm 8 away from the adjustment block 11 is hinged to the bottom of the cabin 2, and the number of the support arms 8 is eight, and the eight support arms 8 are divided into four groups;

[0032] A transmission box 13 is fixedly mounted on the top of the fixing seat 1 , and the transmission box 13 passes through the insides of the two limiting grooves 10 , and a driving mechanism is arranged inside the transmission box 13 .

[0033] A plurality of shock absorbers 7 are fixedly mounted on the top of the cabin 2 , and a protective top plate 3 is fixedly mounted on the top of the shock absorbers 7 .

[0034] In one embodiment, the driving mechanism includes a motor 14, and the motor 14 is fixedly mounted on the rear side of the inner wall of the transmission box 13, the two threaded rods 9 both penetrate the interior of the transmission box 13 and are rotatably connected to the bearings mounted on the side of the transmission box 13, the outer walls of the two threaded rods 9 are fixedly mounted with worm wheels 15, the driving end of the motor 14 is fixedly mounted with a worm 12, and the worm 12 is meshed with the worm wheel 15. Driven by the motor 14, the entire system can operate more stably and efficiently, achieving synchronous operation of the two threaded rods 9, greatly reducing the operating cost of the device, and improving the practicality of the device.

[0035] In one of the preferred embodiments, a sealed soft shield 4 is fixedly connected between the bottom side of the cabin 2 and the top side of the fixing seat 1 to seal the mechanical structure between the bottom of the cabin 2 and the top of the fixing seat 1 to prevent the mechanical structure from being affected by external factors.

[0036] In one of the embodiments, backup batteries 6 are fixedly installed on both sides of the top of the fixing base 1. When the external power supply cannot power the device, the device can be powered by the backup batteries 6 to maintain normal operation of the device.

[0037] In one preferred embodiment, a threaded hole matched with the threaded rod 9 is opened on one side of the adjusting block 11, and the adjusting block 11 is threadedly connected to the threaded rod 9 through the threaded hole opened on one side.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to a power source, a backup battery 6 and a control switch when in use. The parts not involved in the device are the same as the prior art or can be implemented by the prior art. When in use, when it is necessary to adjust the height of the cabin 2, the control motor 14 starts to work, and the driving end of the motor 14 drives the worm 12 to rotate. Through the meshing of the worm 12 and the two worm wheels 15, the two worm wheels 15 rotate synchronously. The rotation of the worm wheel 15 drives the threaded rod 9 to rotate. Through the threaded transmission of the left-handed thread and the right-handed thread on the threaded rod 9 and the sliding relationship between the adjustment block 11 and the limit groove 10, the threaded rod 9 is rotated. The two groups of adjustment blocks 11 move relative to each other or oppositely at the same time. The movement of the adjustment blocks 11 will change the angles on the four groups of support arms 8. When the angle decreases, it will produce a lifting effect on the cabin 2. On the contrary, when the angle decreases, it will cause the cabin 2 to drop. Therefore, the vertical height of the lifeboat 2 is adjusted by mechanical drive, so that the lifeboat 2 can be kept away from the bottom surface, thereby effectively avoiding the impact of mud and rocks and various unknown liquids inside the mine, thereby improving the safety of the lifesaving device. This mechanical drive elevation method not only ensures the stability of the adjustment process, avoids the unstable factors that may be caused by manual adjustment, but also significantly improves the timeliness and effectiveness of the rescue operation. Compared with manual operation, mechanical drive can accurately control the lifting and lowering of the lifeboat 2, and the operator does not need to spend too much time and energy on complex manual adjustments in an emergency, thereby completing the rescue mission more conveniently and safely.

[0039] During the use of the cabin 2, the protective roof 3 plays a key role in the mine collapse process, and can effectively block falling rocks and prevent them from directly hitting the lifeboat 2 and causing damage, thereby protecting the safety of the personnel in the lifeboat 2. At the same time, the setting of the shock absorber 7 effectively buffers the impact on the protective roof 3, significantly enhances its anti-impact ability, and further improves the safety of the device.
