Abstract

The application discloses a bendable belt conveyor belt turning stabilizing device and an implementation process, and relates to the technical field of belt conveyors. The device comprises a bearing frame, a telescopic beam, a roller support and a conical self-aligning roller. The two ends of the telescopic beam are respectively connected with the two sides of the bearing frame. The roller support is arranged on the telescopic beam, and the conical self-aligning roller is arranged on the top of the roller support and is in contact with the upper surface of the belt. The size parameters of the conical self-aligning roller are determined according to the difference between the inner diameter and the outer diameter when the belt turns. The stabilizing device is arranged on the inner side of the conveyor turning, and the conical self-aligning roller is arranged in close contact with the belt. When the belt is running in a curved manner, the different displacement amounts generated by the difference between the inner diameter and the outer diameter at different distances from the center axis of the belt on the inner diameter side of the belt are compensated by the conical self-aligning roller with targeted parameter design, so that the conditions of belt bulging and even belt running on the inner diameter side of the belt are avoided, and the running stability of the belt is greatly improved.

Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and in particular to a belt turning stabilization device and its implementation process for a flexible belt conveyor. Background Technology

[0002] Among various transportation equipment, belt conveyors are the most important, especially in mine production transportation. The conveyor belt, also known as a belt conveyor, runs the entire length of the conveyor and is the most crucial component. In a belt conveyor, the belt serves as both a load-bearing and traction component, used to transport materials and transmit traction force. Under complex conditions, underground transport roadways may require bends to adapt to site requirements. While the belt conveyor facilitates curved transport, the belt itself also bends to accommodate these bends, leading to belt bulging on the inner diameter side.

[0003] Existing technologies have the following problems: When a belt conveyor bends, the outer diameter side of the belt is tensioned, while the inner diameter side is compressed. When the bending angle is too large, the inner diameter side of the belt will bulge. If the bulging area is too large, it will affect the contact transmission between the belt and the conveyor rollers, leading to belt misalignment. Traditional technologies use a belt pressing method to stabilize the belt by installing a pulley on the belt above the rollers. The pulley and rollers limit the belt's undulation, thus stabilizing the belt. However, the pulley constantly generates friction during belt pressing, which greatly increases belt wear and increases maintenance and replacement costs. Summary of the Invention

[0004] To address the above technical problems, this invention provides a flexible belt conveyor belt turning stabilizing device and its implementation process, which saves costs, reduces safety risks, and improves work efficiency.

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

[0006] This invention provides a belt turning stabilizing device for a flexible belt conveyor, including a support frame.

[0007] The support frame is used to support the belt;

[0008] A telescopic beam, the two ends of which are respectively connected to one side of the load-bearing frame;

[0009] The idler bracket is mounted on the telescopic beam.

[0010] A tapered self-aligning idler is disposed on the top of the idler bracket and is in contact with the upper surface of the belt.

[0011] Optionally, the telescopic beam includes an inner beam and an outer beam; one end of the outer beam is rotatably connected to the load-bearing frame, and both ends of the inner beam are slidably connected to the other end of the outer beam.

[0012] Optionally, the side wall of the support frame and one end of the outer beam are provided with pin holes, and the outer beam and the support frame are rotatably connected by inserting pins into the pin holes.

[0013] Optionally, the idler support includes a support column and an idler shaft; the bottom of the support column is connected to the middle of the telescopic beam; the idler shaft is located at the top of the support column; and the tapered self-aligning idler is connected to the idler shaft.

[0014] Optionally, the conical self-aligning idler roller has a frustum-shaped structure.

[0015] Optionally, a bolt is provided at the top of the idler roller shaft, the middle part of the bolt is connected to the other end of the idler roller shaft, and the bolt is detachably connected to the support column.

[0016] Optionally, the tapered self-aligning idler roller can be fitted to the upper surface of the belt by adjusting the included angle between the idler roller shaft and the support column.

[0017] Optionally, the taper of the tapered self-aligning idler is matched with the bending radius of the inner diameter side of the upper surface of the belt.

[0018] This invention also discloses an implementation process for a belt turning stabilization device for a flexible belt conveyor.

[0019] The first step is to measure the turning radius of the belt at the bend, calculate the difference in arc length between the inner and outer sides of the curved belt, and determine the length and cone angle of the conical self-aligning idler based on this difference.

[0020] The second step involves adjusting the support frame to achieve belt bending during transport. The originally parallel support frames change their distance and horizontal angle due to the bending of the belt conveyor. Cylindrical pin holes are arranged on the inner side of the bent belt conveyor of the support frame, connecting with cylindrical pin holes on the telescopic beam via pins to prevent the telescopic beam from detaching from the support frame. Each telescopic beam is connected to a support frame on both sides via pins. When the horizontal angle between the support frames changes, the pin holes on the telescopic beam and the pin holes on the support frame can rotate relative to each other to adapt to the change in horizontal angle between the support frames. When the horizontal distance between the support frames changes, the outer beam of the telescopic beam slides along the inner beam in the middle under pressure to achieve extension and retraction, adapting to the change in distance between the support frames.

[0021] The third step involves connecting the roller bracket to the tapered self-aligning roller via threaded connections, loosening the bolts connecting the bracket column and the roller shaft, and adjusting the roller shaft's angle by rotating it vertically until the lower conical surface of the tapered self-aligning roller is in contact with the upper surface of the belt's inner diameter side. Then, tighten the bolts connecting the bracket column and the roller shaft to allow the tapered self-aligning roller to be driven by the belt.

[0022] The present invention achieves the following technical effects compared to the prior art:

[0023] The flexible belt conveyor belt turning stabilization device and its implementation process in this invention.

[0024] (1) The conical self-aligning idler eliminates the excess material on the inner diameter side of the belt caused by the difference between the inner and outer diameters when the belt is bent, thus avoiding belt bulging or even belt running on the inner diameter side and greatly improving the stability of belt operation.

[0025] (2) The roller bracket is connected to the tapered self-aligning roller by thread. The tapered self-aligning roller can be installed and removed on the roller bracket. The tapered self-aligning roller is connected to the column bracket by bolts. The matching between the tapered self-aligning roller and the upper surface of the inner diameter side of the belt can be adjusted by adjusting the tightness of the bolts. The parameters of the tapered self-aligning roller can be designed specifically for different bending angles of the conveyor, which has strong adaptability to the bending transportation of underground belt conveyors.

[0035] The telescopic beam 2 includes an inner beam 21 and an outer beam 22; one end of the outer beam 22 is rotatably connected to the bearing frame 1, and both ends of the inner beam 21 are slidably connected to the other end of the outer beam 22.

[0036] Both the side wall of the support frame 1 and one end of the outer beam 22 are provided with pin holes.

More specifically, the inner beam 21 is 800mm long, the outer beam 22 is 300mm long, and the outer beams 22 at both ends slide on the inner beam 21 and extend outward by a maximum of 200mm. The telescopic beam 2 has a telescopic range of 800-1200mm. The ends of the outer beams 22 and the conveyor support frame 1 are provided with cylindrical pin holes 5 at a position 800mm above the ground, and are connected by pins 6.

[0037] The idler support 3 includes a support column 31 and an idler shaft 32; the bottom of the support column 31 is welded to the middle of the inner beam 21; the idler shaft 32 is located at the top of the support column 31; and a tapered self-aligning idler 4 is connected to the idler shaft 32.
