Description

Technical Field

[0001] The utility model relates to a reset device for a guiding roller of an underground belt conveyor, belonging to the technical field of leveling the guiding roller of a belt conveyor. Background Technique

[0002] Coal mine belt conveyors are characterized by large transportation volume, complex working environment, strong bearing capacity, and long transportation distance. Whether the belt conveyor can operate normally mainly depends on the driving device, and the installation accuracy of the rollers is particularly important. The rollers are the main components for transmitting power of the belt conveyor and are also the parts prone to failure. Therefore, ensuring the stable operation of the rollers is the top priority of management.

[0003] The guiding roller in the belt conveyor is mainly used to change the running direction of the conveyor belt or press the conveyor belt to increase its wrap angle with the driving roller. The position of the guiding roller, especially the levelness, will change due to roadway deformation or the bulging of the belt conveyor floor foundation, which will in turn lead to problems such as belt deviation and belt overturning. When the change in levelness is slight, it can be adjusted through the adjusting screws on the roller itself during installation. By turning the adjusting screws, the levelness of the guiding roller can be adjusted, so as to achieve the purpose of adjusting the belt deviation. However, the adjustment range of the adjusting screws is limited. Even when replacing the fixing bolts with a smaller model, it can only be adjusted by 3 - 8 mm, and it will cause the reduction of the fixing strength, posing a hidden danger to the safe operation of the belt.

[0004] When the roadway deformation is large and cannot be well adjusted through the above-mentioned self - contained adjusting screws, the measures usually taken to deal with the change in the position of the belt guiding roller are as follows: First, stop the underground production for welding to adjust the roller position. However, in principle, welding is not allowed in underground mines. Even if welding is possible, there are many restrictive conditions during welding, which is rather troublesome. Second, re - make the foundation for the belt guiding roller. Usually, the time for making the foundation will not be less than 7 days, which greatly affects underground production. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an adjustable - level guiding roller device for an underground belt conveyor that can conveniently and quickly adjust the position and levelness of the guiding roller.

[0006] To achieve the above - mentioned purpose, the utility model adopts the following technical solution. A reset device for a guiding roller of an underground belt conveyor includes an adjustment frame, a guiding roller, a mounting seat, and a roller support. The adjustment frame is a rectangular frame formed by welding a vertical first mounting plate, a second mounting plate, a horizontal top plate, and a bottom plate. Four first mounting holes are opened on the first mounting plate, and four second mounting holes are opened on the second mounting plate. The first mounting holes are vertically elongated holes, and the second mounting holes are round holes. A horizontal platform is fixed below the first mounting holes on the first mounting plate. Two threaded holes are opened on the horizontal platform, and vertical jackscrews are threadedly connected to both of the two threaded holes.

[0007] Both ends of the guiding roller are rotatably installed in two mounting seats;

[0008] The two mounting seats correspond to the two adjusting frames one by one. Bolts and nuts cooperate with the first mounting holes to mount the mounting seats on the first mounting plate. The vertical jackscrews are located below the mounting seats, and their ends abut against the mounting seats;

[0009] The two adjusting frames are both installed on the roller support.

[0010] Preferably, the second mounting hole is a horizontal long hole.

[0011] Preferably, two vertical platforms are fixed on the roller support and arranged in parallel on both sides of the adjusting frame. Two upper and lower threaded holes are formed in the vertical platforms, and horizontal jackscrews are threadedly connected in both threaded holes. The ends of the horizontal jackscrews abut against both sides of the second mounting plate.

[0012] Preferably, the cross sections of the two vertical platforms are both L-shaped. One side of the vertical platform is fixedly connected to the side surface of the roller support, and the other side is parallel to the adjusting frame.

[0013] Preferably, a web is fixed inside the adjusting frame. The web is rectangular, and its four sides are respectively welded to the first mounting plate, the second mounting plate, the top plate and the bottom plate.

[0014] Preferably, two horizontal reinforcing rib plates are fixed on both sides of the web.

[0015] Preferably, the length of the first mounting hole is 80 - 120 mm.

[0016] Preferably, the length of the second mounting hole is 50 - 80 mm.

[0017] Preferably, the length of the adjusting frame is 300 - 500 mm.

[0018] Compared with the prior art, the utility model has the following beneficial effects.

[0019] 1. In the utility model, vertical long holes and horizontal long holes are machined on the adjusting frame. The vertical long holes are 80 - 120 mm long, and the horizontal long holes are 50 - 80 mm long, so that the adjustable range of the guiding roller is increased, far greater than the original 3 - 8 mm. In this way, when the roadway deforms, the guiding roller can be leveled through the adjusting frame. Even if the deformation amount of the roadway is large, the adjustment requirements can be met without underground welding or redoing the foundation, which is very convenient and can ensure underground production.

[0020] 2. In the utility model, the length of the adjusting frame is 300 - 500 mm. In this way, the belt storage capacity is increased by 600 - 1000 mm compared with that without the adjusting frame. BRIEF DESCRIPTION OF THE DRAWINGS
