Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, and in particular relates to a wireless anti-overwinding device for material lifting. Background Art

[0002] Overwinding refers to the phenomenon that the lifting height of the lifting material bin exceeds the normal lifting height of the mine entrance due to operational errors. This type of accident often has very serious consequences, such as pulling down the derrick, or breaking the wire rope, causing the lifting material bin to fall to the bottom of the mine and causing a safety accident. Existing mine hoisting equipment will be equipped with an anti-overwinding device to perform safety braking and protect the lifting system.

[0003] Chinese patent application number 202110952710.4 discloses a wireless overwinding prevention device for material hoisting, comprising a mine, a limit assembly, a second cylinder, a first spring, a second motor, a driven wheel, and a cleaning assembly. A gantry is fixed above the mine, and a controller is provided on the upper surface of the gantry. A wire rope take-up roller is fixed to the surface of the rotating shaft. The limit assembly for limiting the wire rope take-up roller is arranged on the outside of a fixed block. The second cylinder is fixed to both ends of the upper portion of the gantry. The first spring is provided at the bottom of a U-shaped frame. The second motor is fixed to the lower outside of the gantry. The wireless overwinding prevention device for material hoisting includes a limit plate and a first cylinder. The limit plate is driven by the first cylinder to rotate, so that a limit block at the bottom end of the limit plate can be engaged with a limit groove on the surface of the wire rope take-up roller. This allows the wire rope take-up roller and the wire rope to be locked in position after the material bin is lifted, improving safety during use.

[0004] The above-mentioned disclosed patent has the following characteristics: 1. When in use, the connecting rod is driven to move by the cylinder, thereby driving the U-shaped frame to move, and its height is adjusted to adjust the range of overwinding prevention. However, when it is in use, the cylinder is exposed to the outside. Due to the large amount of dust at the mine construction site, dust is easily attached to the telescopic end of the cylinder, causing wear during use; 2. When in use, the aggregate box can receive the material bin when the wire rope breaks accidentally and the material bin accidentally falls, but when it is in use, the aggregate box does not have a buffering effect and is not practical enough; 3. When in use, the wire rope is cleaned by the arc cleaning plate. Due to long-term wear, the arc cleaning plate is severely damaged, and it is inconvenient to replace the arc cleaning plate.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 1 is that the disassembly and assembly component 9 includes a disassembly and assembly seat 91, a connecting block 92, an insertion rod 93, a fixing rod 94, a fixing slider 95 and a fixing spring 96, wherein one end of the elastic rod of the cleaning component 8 is fixedly connected to the disassembly and assembly seat 91, a connecting block 92 is provided on one side of the disassembly and assembly seat 91, an insertion rod 93 is provided below the connecting block 92, a fixing rod 94 is provided on one side of the connecting block 92, a fixing slider 95 is provided on one side of the fixing rod 94, and a fixing spring 96 is provided at one end of the fixing slider 95.

When the elastic rod moves to the limiting hole and the limiting rod 97 coincides, the limiting rod 97 is inserted into the limiting hole to fix the elastic rod. Then the fixing rod 94 can be pulled. The fixing rod 94 drives the fixing slider 95 to move and compress the fixing spring 96, so that the fixing rod 94 is disengaged from the fixing hole. Then the arc cleaning plate can be removed and replaced, so that the arc cleaning plate can be easily replaced when the device is in use.

Then, the arc cleaning plate can be removed and replaced, so that the arc cleaning plate can be easily replaced when the device is in use.

[0046] The structure and usage principle of the anti-overwinding component 2, adjustment component 3, rotating component 5, cleaning component 8 and winding component 10 in the present invention have been disclosed in a wireless anti-overwinding device for material lifting disclosed in Chinese patent application number 202110952710.4. Its working principle is that when the wireless anti-overwinding device for material lifting is used, the first motor on the top of the gantry 1 drives the rotating shaft and the wire rope winding roller to rotate to reel the wire rope, so that the wire rope drives the material bin to lift upward from the inside of the mine 11. During the process of reeling in the wire rope, the surface of the wire rope can be cleaned by the collecting box on the top of the gantry 1 and the arc cleaning plate, avoiding the inconvenience caused by manual cleaning. When the material bin pushes the protective plate under the U-shaped frame and triggers the alarm, the controller will turn off the first motor to stop the rotation of the rotating shaft and the wire rope winding roller, thereby When the overwinding prevention height range needs to be adjusted, it is only necessary to open the second cylinders at both ends above the gantry 1 to cooperate with the connecting rod to drive the U-shaped frame on the inner wall of the gantry 1.

[0047] The working principle and use process of the present invention: When the present invention is used, the material bin is driven to be lifted upward from the mine 11 by the winding component 10. During the winding process, the overwinding prevention component 2 is used to prevent the wire rope from being overwound. During the winding process, the wire rope is cleaned by the cleaning component 8. After the winding is completed, the collection box 7 is driven to rotate to the bottom of the material bin by the rotating component 5. When in use, the height of the anti-overwinding component 2 can be adjusted by the adjusting component 3. When the adjusting component 3 is in use, the air of the adjusting component 3 can be adjusted by the protective component 4. The cylinder is protected, and the aggregate box 7 has a buffering effect when in use. When the arc-shaped cleaning plate of the cleaning component 8 needs to be replaced, it can be replaced by disassembling the component 9. When the protective component 4 is in use, the telescopic end of the cylinder of the protective component 4 is easily protected by the rubber telescopic tube 41. When the rubber telescopic tube 41 needs to be replaced, the clamping rod 44 is pulled, and the clamping rod 44 drives the clamping slider 45 to move the compressed clamping spring 46, so that the clamping block 43 is disengaged from the clamping hole, and then the plug 42 can be pulled out, and then the bolt can be removed. Under the action of the movable seat 62, the cylinder of the adjusting assembly 3 is separated from the movable seat, and then the rubber telescopic tube 41 can be removed, so that the device can be used to protect the telescopic end of the cylinder. When the buffer assembly 6 is in use, the collection box 7 moves through the movable connecting rod 65 to drive the damping slider 63 to move on the buffer rod 62 to compress the buffer spring 1 64. At the same time, the collection box 7 will drive the buffer slider 66 to move the compressed buffer spring 2 67, thereby buffering the impact force received by the collection box 7, so that the device can be used to easily adjust the collection box 7. It can buffer the impact force received. When the disassembly and assembly component 9 is in use and the arc cleaning plate needs to be replaced, the elastic rod of the cleaning component 8 is pulled. When the elastic rod moves to the limiting hole and the limiting rod 97 coincides, the limiting rod 97 is inserted into the limiting hole to fix the elastic rod. Then the fixing rod 94 can be pulled. The fixing rod 94 drives the fixing slider 95 to move and compress the fixing spring 96, so that the fixing rod 94 is disengaged from the fixing hole. Then the arc cleaning plate can be removed and replaced, so that the arc cleaning plate can be easily replaced when the device is in use.
