Description

Technical Field

[0001] This utility model belongs to the field of metallurgical technology, and in particular relates to a quick adjustment device for preventing belt misalignment on a tensioning roller. Background Technology

[0002] Typically, blast furnace conveyor belts are equipped with tension rollers. The bearing seats on both sides of the tension rollers are connected to counterweight tensioning devices to ensure the relative stability of the tension rollers when suspended. However, when the conveyor belt transports materials, due to the uneven distribution of the weight and position of the materials on the belt, the tension rollers gradually deviate under the force, resulting in the belt running off to one side after a long period of operation.

[0003] When the conveyor belt slips to one side, it increases the load on the bearing housing on that side, resulting in a high load on one side and a low load on the other. Prolonged operation can cause the bearing housing on the high-load side to overheat and fail. Furthermore, if the tension roller is damaged, the machine needs to be shut down for belt repair, replacement of the tension roller, and the use of single-bucket carts and trucks to transport materials. Based on current market prices, a new tension roller costs approximately 2000 yuan, a single-bucket cart costs 800 yuan per shift, and a truck costs 150 yuan per load. Replacing the tension roller requires approximately 3 hours of single-bucket cart use and transporting 4 truckloads of materials, which is time-consuming and labor-intensive, undoubtedly reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high load on bearing seats, easy damage, high maintenance costs, and time-consuming and labor-intensive processes caused by the easy deviation of the existing tension roller belt. It provides a quick adjustment device to prevent belt deviation on the tension roller, which can adjust the front and rear directions of the left and right bearing seats of the tension roller in time to correct belt deviation, ensure uniform load on both sides of the bearing seats, extend the service life of the tension roller and bearings, avoid coke falling to the ground and belt stoppage for maintenance, improve work efficiency, and reduce costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick adjustment device for preventing belt misalignment on a tension roller includes a tension roller and a belt thereon. A bearing seat is provided on each side of the tension roller. The outer side of the bearing seat is connected to a counterweight tensioning device. Each bearing seat is connected to an adjustment mechanism, which is located diagonally below the bearing seat. The adjustment direction of the adjustment mechanism acting on the bearing seat is parallel to the normal operating direction of the belt.

[0007] Furthermore, the adjusting mechanism includes a first wire rope, a turnbuckle, and a second wire rope. One end of the first wire rope is connected to the bearing seat, and the other end is connected to the front end of the turnbuckle. One end of the second wire rope is connected to the rear end of the turnbuckle, and the other end is connected to the ground.

[0008] Furthermore, the first wire rope, the turnbuckle, and the second wire rope are all on the same axis.

[0009] Furthermore, the angle α between the first wire rope and the horizontal direction is set to 45°~55°.

[0010] Furthermore, the two adjusting mechanisms are set parallel to each other, and the connection points of the two second steel wire ropes with the ground are on the same horizontal line.

[0011] In the technical solution of this utility model, the front-to-back distance between the left and right bearing seats of the tensioning roller is adjusted by tightening and loosening the turnbuckle, which can correct the belt deviation in time and ensure that the belt runs in the center of the tensioning roller. This ensures that the bearing seat on one side will not be damaged due to high load, and ensures that the belt runs smoothly. It also reduces the need to stop the belt and replace the roller due to damage to the roller bearing seat, improves work efficiency, and reduces subsequent maintenance costs.

[0017] Example

[0018] To make this utility model clearer, the following description further illustrates a quick adjustment device for preventing belt misalignment on a tension roller. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0019] See Figure 1 A quick adjustment device for preventing belt misalignment on a tension roller includes a tension roller 1 and a belt 2 on it. A bearing seat 3 is provided on each side of the tension roller 1, and the outer side of the bearing seat 3 is connected to a counterweight 4. The device is characterized by:

[0020] See Figure 1 and Figure 2Each bearing housing 3 is connected to an adjustment mechanism 5. The adjustment mechanism 5 is located diagonally below the bearing housing 3, and the adjustment direction of the adjustment mechanism 5 acting on the bearing housing 3 is parallel to the normal operating direction of the belt 2.

[0021] The adjusting mechanism 5 includes a first wire rope 51, a turnbuckle 52, and a second wire rope 53. One end of the first wire rope 51 is connected to the bearing seat 3, and the other end is connected to the front end of the turnbuckle 52. One end of the second wire rope 53 is connected to the rear end of the turnbuckle 52, and the other end is connected to the ground 6.

[0022] See Figure 2 and Figure 3 The first wire rope 51, turnbuckle 52 and the second wire rope 53 are all on the same axis, and the two adjusting mechanisms 5 are set parallel to each other, and the connection points of the two second wire ropes 53 with the ground 6 are on the same horizontal line.

[0023] In this embodiment, see Figure 4 When belt 2 deviates to the left, it indicates that the left bearing housing is under heavy load and its horizontal position is ahead of the right bearing housing. At this time, the turnbuckle on the left can be tightened to pull the left bearing housing backward. When the left bearing housing is behind the right bearing housing, the belt will move to the right. When the belt moves to the middle of the tension roller, the turnbuckle on the left can be loosened again to make the bearing housings on both sides on the same horizontal line, thus completing the adjustment work of the belt running in the center of the tension roller.

[0024] See Figure 5 When belt 2 deviates to the right, it indicates that the right bearing housing is under heavy load and its horizontal position is in front of the left bearing housing. At this time, the turnbuckle on the right side can be tightened to pull the right bearing housing backward. When the right bearing housing is behind the left bearing housing, the belt will move to the left. When the belt moves to the middle of the tension roller, the turnbuckle on the right side can be loosened again to make the bearing housings on both sides on the same horizontal line, thus completing the adjustment work of the belt running in the center of the tension roller.

[0025] This invention adjusts the front-to-back distance of the bearing seat by adjusting the tightness of the turnbuckle, ensuring that the belt runs in the center of the tension roller. The device of this invention can quickly adjust the deviation of the tension roller without stopping the machine to replace the tension roller, reducing the need to stop the belt to replace the tension roller, which is expected to save about 3,400 yuan.

[0026] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
