Description

Technical Field

[0001] This utility model relates to the technical field of mine machinery braking equipment, specifically a safety braking device for a hoist. Background Technology

[0002] A hoist is a major transportation device in mining engineering that connects underground and the surface. A coal mine hoist is a hoisting machine installed on the ground that uses steel wire ropes to drive a hoisting container along the shaft or inclined ramp. It is used to hoist coal, ore, gangue, personnel, materials, tools, and equipment in vertical and inclined shafts. During use, a braking device is required to brake the hoist.

[0003] However, existing hoist safety braking devices have the following drawbacks:

[0004] (1) The existing safety braking device of the hoist has a weak heat dissipation function. Traditional braking devices usually rely on natural cooling after use, which takes a long time and is inefficient. The heat is not dissipated for a long time, which causes the device to easily degrade or fail due to overheating, and reduces its durability.

[0005] (2) The existing safety braking device of the hoist has weak dust prevention function. As the braking device works in the coal mine for a long time, coal blocks are easily attached to the surface, which reduces the braking effect and shortens the life of the device. Utility Model Content

[0006] The purpose of this invention is to provide a safety braking device for a hoist, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety braking device for a hoist, comprising a base plate, a water tank fixedly connected to one side of the top of the base plate, a condenser fixedly connected to the top of the water tank, a water pump fixedly connected to the inner bottom wall of the water tank, a connecting pipe fixedly connected to one end of the water pump, a cooling plate fixedly connected to one end of the connecting pipe, a limit frame fixedly connected to the top of the base plate, a first servo motor fixedly connected to the inner side wall of the limit frame, an adjusting screw fixedly connected to the output end of the first servo motor, an adjusting slider threadedly connected to the outer surface of the adjusting screw, and a... An extension rod is provided, with a storage rod slidably connected to its outer surface. A fixing screw is threadedly connected to the inside of the extension rod. A limit groove is provided on one side of the top of the base plate, and a limit slider is slidably connected inside the limit groove. A telescopic rod is fixedly connected to the side of the limit slider, and a spring is provided on the outer surface of the telescopic rod. A limit block is fixedly connected to one end of the telescopic rod, and a baffle is fixedly connected to the top of the limit slider. A second servo motor is fixedly connected to the top of the base plate, and a brake rod is fixedly connected to the output end of the second servo motor. A wheel is fixedly connected to one end of the brake rod, and a pull rope is provided on the outer surface of the wheel.

[0008] Optionally, the top of the cooling chip is provided with a connecting groove, and the storage rod is connected to the connecting groove. The connecting groove connects and fixes the cooling chip and the storage rod, and the storage rod supports and fixes the cooling chip to prevent the cooling chip from falling off.

[0009] Optionally, the inner wall of the limiting slide is provided with a limiting slot, and the limiting block fits into the limiting slot. When the limiting block is inserted into the limiting slot, the limiting slot limits the limiting block, so that the position of the limiting block is fixed inside the limiting slot, thereby fixing the position of the baffle as well.

[0010] Optionally, the base plate is internally threaded with a mounting screw, and a limiting plate is fixedly connected to the bottom surface of the mounting screw. A cone is fixedly connected to the bottom of the limiting plate. Rotating the mounting screw causes the cone to rotate and enter the ground, thereby installing the device. The limiting plate can limit the position of the cone.

[0011] Optionally, a fixing groove is provided on one side of the limiting block, and the spring is connected to the fixing groove. The fixing groove connects and fixes the spring and the limiting block. When the spring extends or retracts, it will drive the limiting block to move accordingly.

[0012] Optionally, a circular slot is provided on the side of the limiting frame, and the brake rod is rotatably connected to the inside of the circular slot. When the brake rod rotates inside the circular slot, the circular slot limits the brake rod and prevents the brake rod from shifting position.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This hoist safety braking device, through the configuration of a water tank, condenser, water pump, connecting pipe, cooling plate, first servo motor, adjusting screw, adjusting slider, extension rod, receiving rod, and fixing screw, is powered by an external power source. The first servo motor drives the adjusting screw to rotate, which in turn moves the adjusting slider. After adjusting the position of the receiving rod, the fixing screw is rotated to make the inner wall of the cooling plate fit against the surface of the braking mechanism. At this time, the water pump runs, driving water from the water tank into the connecting pipe. After being cooled by the condenser, the water is delivered to the inside of the cooling plate. Thus, after the device is used, the surface of the braking device is liquid-cooled, achieving an effective heat dissipation effect.

[0015] 2. This hoist safety braking device, through the arrangement of a limiting groove, a limiting slider, a telescopic rod, a spring, a limiting block, and a baffle, operates as follows: During use, the limiting slider is slid into the limiting groove, which simultaneously limits its movement. When the limiting slider reaches a certain position, the spring's tension causes the telescopic rod to extend, which in turn causes the limiting block to engage in a groove on the inner wall of the limiting groove, thus fixing the baffle in place. The baffle effectively protects the device's surface from dust, preventing coal particles from adhering to the surface during prolonged operation in coal mines, which could reduce braking effectiveness and shorten the device's lifespan.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a safety braking device for a hoist, including a base plate 1, a water tank 2 fixedly connected to one side of the top of the base plate 1, a condenser 3 fixedly connected to the top of the water tank 2, a water pump 4 fixedly connected to the inner bottom wall of the water tank 2, a connecting pipe 5 fixedly connected to one end of the water pump 4, a cooling plate 6 fixedly connected to one end of the connecting pipe 5, a limit frame 7 fixedly connected to the top of the base plate 1, a first servo motor 8 fixedly connected to the inner side wall of the limit frame 7, and an adjusting screw 9 fixedly connected to the output end of the first servo motor 8 for adjusting... An adjusting slider 10 is threaded onto the outer surface of the screw 9. An extension rod 11 is fixedly connected to the bottom of the adjusting slider 10. A storage rod 12 is slidably connected to the outer surface of the extension rod 11. A fixing screw 13 is threaded onto the inside of the extension rod 11. A limiting groove 14 is formed on one side of the top of the base plate 1. A limiting slider 15 is slidably connected inside the limiting groove 14. A telescopic rod 16 is fixedly connected to the side of the limiting slider 15. A spring 17 is provided on the outer surface of the telescopic rod 16. A limiting block 18 is fixedly connected to one end of the telescopic rod 16. The limiting slider 1... A baffle 19 is fixedly connected to the top of the 5, and a second servo motor 20 is fixedly connected to the top of the base plate 1. A brake rod 21 is fixedly connected to the output end of the second servo motor 20, and a rotating wheel 22 is fixedly connected to one end of the brake rod 21. A pull rope 23 is provided on the outer surface of the rotating wheel 22. When the device is connected to an external power source, the first servo motor 8 is started, which drives the adjusting screw 9 to rotate, thereby driving the adjusting slider 10 to move. After adjusting the position of the storage rod 12, the fixing screw 13 is rotated to make the inner wall of the cooling chip 6 fit against the surface of the braking mechanism. At this time, the water pump 4 runs, driving the water tank. Water from step 2 enters the connecting pipe 5, and after being cooled by the condenser 3, it is delivered to the interior of the cooling plate 6. After the device is used, the surface of the braking device is liquid-cooled. The limiting slider 15 is slid into the limiting groove 14, and the limiting groove 14 limits the limiting slider 15. When the limiting slider 15 slides to a certain position, the spring 17 drives the telescopic rod 16 to extend due to its own tension, which in turn drives the limiting block 18 to be locked into the slot in the inner wall of the limiting groove 14, thereby fixing the position of the baffle 19. The baffle 19 can protect the surface of the device.

[0023] The top of the cooling chip 6 is provided with a connecting groove, and the storage rod 12 is connected to the connecting groove. The connecting groove connects and fixes the cooling chip 6 and the storage rod 12, and the storage rod 12 supports and fixes the cooling chip 6 to prevent the cooling chip 6 from falling off.

[0024] The inner side wall of the limiting slide 14 is provided with a limiting slot 24. The limiting block 18 fits into the limiting slot 24. When the limiting block 18 is inserted into the limiting slot 24, the limiting slot 24 limits the limiting block 18, so that the position of the limiting block 18 is fixed inside the limiting slot 24, thereby fixing the position of the baffle 19 as well.

[0025] The base plate 1 is internally threaded with a mounting screw 25. A limiting plate 26 is fixedly connected to the bottom surface of the mounting screw 25. A cone 27 is fixedly connected to the bottom of the limiting plate 26. Rotating the mounting screw 25 causes the cone 27 to rotate and enter the ground, thereby installing the device. The limiting plate 26 can limit the position of the cone 27.

[0026] A fixing groove is provided on one side of the limiting block 18. The spring 17 is connected to the fixing groove. The fixing groove connects and fixes the spring 17 and the limiting block 18. When the spring 17 extends or retracts, it will drive the limiting block 18 to move accordingly.

[0027] The side of the limiting frame 7 has a circular slot 28. The brake rod 21 is rotatably connected to the inside of the circular slot 28. When the brake rod 21 rotates inside the circular slot 28, the circular slot 28 limits the brake rod 21 to prevent the brake rod 21 from shifting position.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: The device is powered by an external power source. The first servo motor 8 is started and drives the adjusting screw 9 to rotate, which in turn drives the adjusting slider 10 to move. After adjusting the position of the storage rod 12, the fixing screw 13 is rotated to make the inner wall of the cooling chip 6 fit against the surface of the braking mechanism. At this time, the water pump 4 runs and drives the water in the water tank 2 to flow into the connecting pipe 5. After being cooled by the condenser 3, the water is delivered to the inside of the cooling chip 6. After the device is used, the surface of the braking device is liquid cooled. The limiting slider 15 is slid into the limiting groove 14. At the same time, the limiting groove 14 limits the limiting slider 15. When the limiting slider 15 slides to a certain position, the spring 17 drives the telescopic rod 16 to extend due to its own tension, which in turn drives the limiting block 18 to be locked into the slot in the inner wall of the limiting groove 14, thereby fixing the position of the baffle 19. The baffle 19 can protect the surface of the device.

[0030] The second step: The connecting groove connects and fixes the cooling chip 6 and the storage rod 12, and the storage rod 12 supports and fixes the cooling chip 6 to prevent the cooling chip 6 from falling. When the limiting block 18 is inserted into the limiting slot 24, the limiting slot 24 limits the limiting block 18, fixing the position of the limiting block 18 inside the limiting slot 24, thereby fixing the position of the baffle 19 as well. Rotating the installation screw 25 causes the cone 27 to rotate and enter the ground, thereby installing the device. The limiting plate 26 can limit the position of the cone 27.

[0031] The third step: The fixing groove connects and fixes the spring 17 and the limiting block 18. When the spring 17 extends or retracts, it will drive the limiting block 18 to move accordingly. When the brake rod 21 rotates inside the circular slot 28, the circular slot 28 limits the brake rod 21 to prevent the brake rod 21 from shifting position.
