Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal mine mechanical device, concretely relates to a wedge ring's retreat and moves force device. BACKGROUND

[0002] In mine hoisting operation, the lifting steel wire rope plays a vital role, and inevitably occurs elongation when it bears heavy load for a long time. When the elongation exceeds the maximum elongation of the balance cylinder, the normal operation of the cage (skip) will be seriously affected, at which time the length of the lifting steel wire rope needs to be shortened through stringing operation to restore the balance of the cage (skip) and ensure the continuous and safe operation of the mine hoisting work.

[0003] However, in the stringing process, the ring core of the automatic balance suspension device is under the action of tensioning tension for a long time, and it is extremely difficult to retreat and remove. The traditional force removing method mainly includes hammering method and wind pick impact method. The hammering method is to knock the wedge ring core by artificial hammer head to try to loosen and remove it. This method has obvious defects. First, in the working environment of the mine, the space is usually small, and the operator cannot effectively hammer due to the limited operation space, and the surrounding shaft facilities are easily damaged due to the limited operation space. Second, the hammer head is easy to fall due to the reaction force or the operator's mistake during the hammering process. Once it falls and damages the key facilities in the shaft, such as cables and pipelines, it will cause the interruption of mine production, and the repair of facilities not only consumes time and effort, but also causes huge economic loss.

[0004] The wind pick impact method also has many problems. The impact force generated by the wind pick during work is large, which can exert a large force on the wedge ring core to a certain extent, but it is difficult to accurately control the impact force in a small space, which can easily cause accidental damage to the surrounding environment and equipment. Moreover, the wind pick and its attached equipment are relatively bulky, which is very inconvenient to carry and operate in the limited space of the mine, further increasing the labor intensity of the operator. In addition, whether it is hammering method or wind pick impact method, the working efficiency is very low, and it often takes a lot of time to remove a wedge ring core, which seriously affects the normal maintenance and operation efficiency of the mine hoisting system.

[0005] In summary, the traditional force removing method cannot meet the requirements of modern mine hoisting operation for high efficiency, safety and convenience, therefore, it is of great practical significance to develop a new type of wedge ring core removing device, which can effectively solve the existing problems, improve the maintenance efficiency and safety of the mine hoisting system, and ensure the smooth progress of mine production.

[0027] like Figure 1 , Figure 2 As shown, this embodiment includes a main body of the device, which includes a fixing component and a force-relieving component. The fixing component and the force-relieving component are welded and fixed together. The force-relieving component includes a jack 1, a top plate 2, and a bottom plate 3. The top plate 2 and the bottom plate 3 are connected and fixed together by two guide rods 4. The jack 1 is located between the two guide rods 4. A guide plate 5 is welded and fixed to the bottom of the jack 1. The sides of the guide plate 5 are attached to the two guide rods 4. The guide plate 5 prevents the jack 1 from tilting. A guide shaft 6 is provided at the bottom of the guide plate 5. The guide shaft 6 makes linear displacement through the jack 1. The guide shaft 6 pushes the wedge-shaped ring 7 downward and separates it from the wedge-shaped device 8. The fixing component includes two clamping plates 9. The two clamping plates 9 are fixed to both sides of the wedge-shaped device 8. The tops of the two clamping plates 9 are welded and fixed to the bottom plate 3.

[0028] The fixing assembly, primarily used to securely mount the entire device onto the wedge-shaped device 8, comprises two clamping plates 9. The clamping plates 9 are made of high-strength metal, such as high-quality carbon steel or alloy steel, possessing sufficient strength and rigidity to withstand various forces generated during the unloading process. The shape of the clamping plates 9 is designed to fit the contours of the two sides of the wedge-shaped device 8, allowing for a tight fit. Screw holes are provided at both ends of the clamping plates 9; the size and thread specification of the screw holes are determined by the selected bolts 11. Reliable fixing of the clamping plates 9 to the wedge-shaped device 8 is achieved by passing the bolts 11 through the top of the wedge-shaped device 8 and screwing them into the screw holes of the clamping plates 9. The tops of the two clamping plates 9 are welded to the base plate 3 in the unloading assembly. The welded areas are carefully treated to ensure welding quality, making the fixing assembly and the unloading assembly a unified whole, preventing loosening or displacement during operation.

[0029] The force relieving assembly is the core part for achieving the dismounting of the wedge-shaped ring core 7, mainly composed of a jack 1, a top plate 2, a bottom plate 3, a guide rod 4 and a guide shaft 6 and the like. The top plate 2 and the bottom plate 3 are made of metal plates, having good flatness and bearing capacity. The top plate 2 and the bottom plate 3 are connected and fixed through the two guide rods 4, the guide rods 4 are made of high-strength alloy steel, and the surface thereof is finely processed, having low roughness, so as to ensure smooth sliding during the movement of the guide shaft 6. The two ends of the guide rod 4 are connected with the top plate 2 and the bottom plate 3 respectively, the guide rod 4 passes through the top plate 2 and is fixed through a nut 12 above the top plate 2, the nut 12 is tightened to firmly lock the guide rod 4 on the top plate 2, preventing displacement of the guide rod 4 during work. The jack 1 is installed between the two guide rods 4, the jack 1 is a hydraulic jack 1 of appropriate specification, having sufficient jacking force and stroke, capable of meeting the working requirements of the dismounting of the wedge-shaped ring core 7. The bottom of the jack 1 is welded with a guide plate 5, the guide plate 5 is made of a metal plate, the side edge thereof is tightly fitted with the two guide rods 4, preventing the jack 1 from tilting during work, ensuring that the force of the jack 1 is accurately transmitted along the direction of the guide shaft 6. The guide plate 5 is provided with the guide shaft 6, the guide shaft 6 and the guide plate 5 are connected in a suitable manner, such as welding or threaded connection, ensuring firm connection. The bottom plate 3 is provided with a through hole 10, the guide shaft 6 penetrates the bottom plate 3 through the through hole 10. During the work of the jack 1, the hydraulic medium is compressed in the hydraulic cylinder to form a certain pressure, causing the jack 1 to produce mechanical linear reciprocating motion, thereby pushing the guide shaft 6 to make linear displacement downward along the through hole 10, the guide shaft 6 accurately pushes the wedge-shaped ring core 7 to move downward during the movement, so as to separate the wedge-shaped ring core 7 from the wedge-shaped device 8, achieving the purpose of force relieving.

[0030] The bottom plate 3 is provided with a through hole 10, and the guide shaft 6 penetrates the bottom plate 3 through the through hole 10.

[0031] The clamping plate 9 is provided with a threaded hole at both ends, and a bolt 11 is arranged on the threaded hole, the bolt 11 penetrates the top of the wedge-shaped device 8, and the clamping plate 9 is fixed with the wedge-shaped device 8 through the bolt 11.

[0032] The guide rod 4 penetrates the top plate 2, and the top of the guide rod 4 is fixed with the top plate 2 through the nut 12.

[0033] The wedge ring unloading device is based on the working principle of the hydraulic jack 1 to realize the unloading operation of the wedge ring core 7. When the wedge ring core 7 needs to be unloaded, first, the two clamping plates 9 of the fixed assembly are firmly installed on both sides of the wedge device 8 through the bolts 11, so that the whole device is stably positioned in the working position. Then, the hydraulic jack 1 in the unloading assembly is started, and the hydraulic medium of the hydraulic jack 1 is compressed in the hydraulic cylinder to form a certain pressure. According to Pascal's law, the pressure will uniformly act on the piston of the hydraulic jack 1 to make the piston generate an upward thrust. Due to the cooperation of the guide plate 5 welded at the bottom of the hydraulic jack 1 and the guide rod 4, it is ensured that the hydraulic jack 1 can only move linearly along the direction of the guide rod 4 and cannot be inclined or deviated. The thrust of the hydraulic jack 1 is transmitted to the guide shaft 6 through the guide plate 5, and the guide shaft 6 moves linearly downward in the through hole 10 of the bottom plate 3 to accurately act on the wedge ring core 7, giving the wedge ring core 7 an opposite thrust to overcome the friction and tension between the wedge ring core 7 and the wedge device 8, so that the wedge ring core 7 gradually moves downward and separates from the wedge device 8.

[0034] After the wedge ring core 7 is separated from the wedge device 8, a long crowbar can be inserted into the center of the wedge ring to further adjust the position of the wedge ring core 7 by moving the crowbar up and down, and at the same time, the auxiliary rope head is pulled by the hand-operated hoist to realize the stringing operation of the hoisting steel wire rope according to the requirements of the mine hoisting steel wire rope stringing process. The whole process is simple and efficient, and the stable thrust of the hydraulic jack 1 realizes rapid docking, greatly saves the stringing time, reduces the labor intensity of the operator, and can ensure the quality of the hoisting steel wire rope stringing, so that the hoisting system after stringing works stably, safely and reliably.
