Description

Technical Field

[0001] This utility model relates to the field of mining machinery safety technology, and in particular to a safety protection device for a mining hoist. Background Technology

[0002] As a core piece of equipment in the mining process, the mine hoist is responsible for the vertical transportation of personnel and materials. Its safety and reliability are directly related to the mine's production efficiency, economic benefits, and the safety of miners. With the continuous increase in mining depth and the expansion of mining scale, the mine hoist faces more complex working conditions and higher safety risks, which puts forward higher requirements for the performance and function of safety protection devices.

[0003] Because the wire rope is partially wound on the left and right sides of the winch roller when it is wound on the roller, it is often in a downward inclined state when the wire rope is unwound. Therefore, the braking device is usually installed on the wire rope roller. In this case, there is a deviation in the braking of the wire rope, especially for the wire rope located at the left or right end, the braking effect is poor and the protection effect is poor.

[0004] The existing patent (publication number: CN221565470U) discloses a safety protection device for a mining hoist. This device guides the wire rope vertically downwards using multiple guide rollers. A safety system controls the installation frame to move towards the guide rollers, and a clamping component presses the wire rope between the guide rollers and the clamping component, improving safety performance. Under normal conditions, the adjusting frame maintains a safe distance between the guide rollers and the clamping component. Furthermore, in the event of a power failure or under the control of the safety system, the adjusting frame can pull the clamping component towards the guide rollers, further tightening the wire rope on the guide rollers, thus enhancing safety.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing safety protection devices for mine hoists are not convenient for braking and deceleration when the hoist malfunctions, which could lead to serious accidents such as collisions and falls, affecting the safety of the hoist. Furthermore, they are not convenient for reducing the impact force on personnel and materials during emergency braking or accidents, thereby increasing the possibility of personnel injury and affecting the protection of miners' lives.

[0006] Therefore, a safety protection device for mine hoists is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A safety protection device for a mine hoist includes a base 1, with support rods 2 fixedly connected to both sides of the base 1, a deceleration assembly 4 provided on the outer side of the support rods 2, and a protective assembly 5 provided on the inner side of the deceleration assembly 4.

[0029] The deceleration assembly 4 includes a movable frame 401 slidably connected to the outside of the support rod 2. A controller 402 is fixedly connected to the inside of the movable frame 401. A hydraulic telescopic rod 403 is fixedly connected inside the movable frame 401. A brake thrust plate 404 is fixedly connected to the output end of the hydraulic telescopic rod 403. A transmission connecting block 405 is fixedly connected to the inside of the brake thrust plate 404. The transmission connecting block 405 is slidably connected to the movable frame 401. A friction brake block 406 is fixedly connected to the inside of the transmission connecting block 405. Friction auxiliary blocks 407 are fixedly connected to both sides of the friction brake block 406.

[0030] In this embodiment: When the controller 402 receives a signal indicating an abnormality in the operation of the mine hoist, the controller 402 immediately activates the hydraulic telescopic rod 403 inside the moving frame 401. The output end of the hydraulic telescopic rod 403 pushes the brake thrust plate 404 to move closer to the support rod 2. The brake thrust plate 404 drives the transmission connecting block 405, which is fixedly connected to it, to move synchronously. Since the transmission connecting block 405 is slidably connected to the moving frame 401, its movement is ensured to be smooth. The transmission connecting block 405 then pushes the inner friction brake block 406 and the friction auxiliary blocks 407 on both sides of the friction brake block 406 to move closer to the support rod 2. Finally, the friction brake block 406 and the friction auxiliary blocks 407 come into close contact with the sliding groove inside the support rod 2, using friction to generate a strong braking force, which slows down the material carrying platform 502 associated with the support rod 2, thereby stopping the hoist and effectively preventing further deterioration of the dangerous situation.

[0031] Specifically, such as Figure 3As shown, the protective component 5 includes a support crossbar 501 fixedly connected to the inner side of the movable frame 401. A material carrying platform 502 is fixedly connected to the inner side of the support crossbar 501. An airbag controller 503 is fixedly connected to the rear side of the material carrying platform 502. A safety buffer airbag 504 is provided at the output end of the airbag controller 503. The safety buffer airbag 504 is located inside the material carrying platform 502.

[0032] Specifically, such as Figure 3 As shown, a pressure sensor 505 is provided on the rear side of the safety buffer airbag 504, and a data analysis processor 506 is electrically connected to the outside of the pressure sensor 505.

[0033] Specifically, such as Figure 3 As shown, a protective housing 507 is bolted to the rear side of the material carrying platform 502. The protective housing 507 is located outside the airbag controller 503 and the data analysis processor 506.

[0034] In this embodiment: when the hoist experiences emergency braking or an accident, its airbag controller 503 immediately receives a corresponding signal. Then, the airbag controller 503 quickly activates, inflating the safety buffer airbag 504 located inside the material carrying platform 502, causing it to rapidly expand and deploy. During the buffering process, the pressure sensor 505 on the rear side of the safety buffer airbag 504 begins to operate, monitoring the pressure data inside the airbag in real time and transmitting this data to the electrically connected data analysis processor 506. The data analysis processor 506 analyzes and processes the pressure data to determine whether the airbag's buffering effect is normal. If the pressure... If the data shows poor buffering effect or abnormality, the data analysis processor 506 will feed back the relevant information to the external control system. At the same time, the support crossbar 501, which is fixedly connected to the inside of the moving frame 401, always firmly supports the material carrying platform 502, ensuring its stability during operation. The protective shell 507, which is bolted to the rear of the material carrying platform 502, provides protection for the airbag controller 503 and the data analysis processor 506, protecting them from dust and humid air, and ensuring that they can work continuously and stably, thereby providing reliable protection for personnel and materials on the material carrying platform 502.

[0035] Specifically, such as Figure 4 As shown, a top plate 3 is fixedly connected to the top of the support rod 2, and a lifting mechanism braking device 6 is fixedly connected to the top of the top plate 3.

[0036] Specifically, such as Figure 5 As shown, the material carrying platform 502 is fitted with an edge guardrail 7 on its front side, and a positioning rod 8 is slidably connected to the top of the material carrying platform 502, which is engaged with the edge guardrail 7.

[0037] In this embodiment: By setting up a top plate 3 and a hoisting mechanism braking device 6, during the installation of the mine hoist, the support rod 2 is first securely connected to the base 1, then the top plate 3 is fixed to the top of the support rod 2, and then the hoisting mechanism braking device 6 is installed on the top of the top plate 3. When the hoist is running normally, the hoisting mechanism braking device 6 is connected to the hoisting hook 9 through a steel rope to hoist personnel or materials. By setting up an edge guardrail 7 and a positioning rod 8, before the material carrying platform 502 is put into use, the edge guardrail 7 is snapped onto the front side of the material carrying platform 502, and the positioning rod 8 is slidably installed on the top of the material carrying platform 502, and the positioning rod 8 is aligned with the edge guardrail 7. The guardrail 7 is fixed in place. When hoisting personnel or materials, the personnel or materials are placed on the material carrying platform 502. The positioning rod 8 and the edge guardrail 7 work together to prevent personnel from accidentally climbing over the edge of the material carrying platform 502 and to prevent materials from falling off due to shaking or bumping during transportation. After transportation, the positioning rod 8 can be slid to separate it from the edge guardrail 7, which facilitates loading and unloading of materials or personnel entering and exiting the material carrying platform 502. This limits the range of movement of personnel and materials on the material carrying platform 502, significantly reducing the risk of personnel injury and material loss during transportation and improving the safety and reliability of mine hoist transportation.

[0038] Specifically, such as Figure 5 As shown, a hoisting hook 9 is fixedly connected to the top of the material carrying platform 502, and an alarm warning device 10 is installed on the top of the material carrying platform 502.

[0039] Specifically, such as Figure 1 As shown, an anti-slip pad 11 is attached to the bottom of the base 1. The anti-slip pad 11 is made of rubber.

[0040] In this embodiment: By setting up a hoisting hook 9 and an alarm warning device 10, before hoisting operations, the hoisting hook 9 is connected to the hoisting mechanism braking device 6, and the hoisting mechanism braking device 6 is started. The material carrying platform 502 achieves vertical transportation through the hoisting hook 9. When abnormal situations occur during the operation of the hoist, such as speed loss or equipment failure, the alarm warning device 10 on the top of the material carrying platform 502 will issue an alarm under the control of the controller 402, alerting the surrounding staff that there is a problem with the hoist and that timely measures need to be taken to avoid further expansion of the accident, thus ensuring the safety of personnel and equipment at the mine operation site. By setting up an anti-slip mat 11, when installing the mine hoist safety protection device, the rubber anti-slip mat 11 is glued to the bottom of the base 1. The anti-slip mat 11 utilizes its own high friction characteristics to increase the friction between the device and the ground, effectively preventing the entire device from shifting or tipping over due to vibration or external forces during operation.

[0041] Working Principle: During mining operations, the hoisting mechanism's braking device 6 is fixed to the hoisting hook 9 via a steel cable to achieve vertical transportation of personnel or materials. When an abnormality occurs during the operation of the hoisting mechanism's braking device 6, such as excessive speed or a broken steel cable, the controller 402 receives the abnormal signal and immediately activates the hydraulic telescopic rod 403. The output end of the hydraulic telescopic rod 403 then pushes the brake thrust plate 404, transmission connecting block 405, and friction brake block 406 towards the support rod 2. The friction brake block 406 and friction auxiliary block 407 then contact the sliding groove inside the support rod 2, using friction to decelerate the material carrying platform 502, thereby stopping the hoist and preventing further danger. Simultaneously, the airbag controller 503 at the rear of the material carrying platform 502 receives the abnormal signal and quickly activates the safety buffer airbag 504 for inflation. The safety buffer airbag 504 is located on the material carrying platform 502. 2. Inside, during emergency braking of the hoist, a buffer is provided for personnel and materials on the material carrying platform 502 to reduce impact injuries caused by sudden stopping. The pressure sensor 505 monitors the pressure inside the safety buffer airbag 504 in real time and transmits the data to the data analysis processor 506. The data analysis processor 506 judges the buffering effect of the airbag based on the pressure data. If the pressure is abnormal, it can promptly feed back to the controller 402 for corresponding adjustments. The protective shell 507 protects the airbag controller 503 and the data analysis processor 506 from external environmental interference and damage. The edge guardrail 7 on the front side of the material carrying platform 502 and the positioning rod 8 on the top prevent personnel and materials from falling during transportation. At the same time, the alarm 10 sounds an alarm to remind surrounding personnel to pay attention to safety. The rubber anti-slip pad 11 at the bottom of the base 1 increases the friction between the device and the ground, making the entire device more stable during operation and preventing displacement due to vibration or external force.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
