Description

Technical Field

[0001] The utility model relates to the technical field of tubular conveyors, in particular to a mechanical tubular conveyor belt automatic deviation-correcting device. Background Art

[0002] Tubular belt conveyors are closed-structure conveyor belts characterized by zero dust, leakage, or spillage during conveying. They can also bend and transport at steep angles, making them widely used in industries such as mining, coal, cement, and metallurgy. However, during tubular belt conveying operations, uneven distribution of cargo, uneven roller pressure, and various environmental factors can cause the conveyor belt to twist and deviate, causing materials to deviate from their intended location.

[0003] The deviation of tubular belt conveyors often causes great harm, such as long-distance belt tearing, belt reversal, personal injury, etc. Therefore, the prevention and treatment of tubular belt conveyor belt deviation failure is an important task for safe production.

[0004] Defects and shortcomings of existing technology:

[0005] There are three main methods for adjusting the deviation of existing tubular belt conveyors:

[0006] 1. Manual adjustment, that is, manually adding shims to the rollers to tilt the rollers relative to the tubular belt, thereby adjusting the deviation. This adjustment method is time-consuming, labor-intensive, and inefficient.

[0007] 2. Electronic control adjustment: The electronic control components are used to tilt the rollers and adjust the belt. However, the use of electronic control components has high requirements for the use environment, short service life and high maintenance costs.

[0008] 3. Hydraulic adjustment is similar to electronic control adjustment. It uses hydraulic components to tilt the rollers and adjust the belt. However, its service life and maintenance are also a big problem. It is not a good way for enterprises.

[0009] In order to achieve automatic belt deviation correction during tubular conveyor operation, reduce belt wear, and ensure smooth and reliable material transportation, a mechanical tubular conveyor automatic deviation correction device was developed for use in the tubular section.

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0034] like Figures 1 to 7As shown, the utility model is a mechanical tubular conveyor belt automatic correction device, which includes a support plate 1, a roller mechanism 2 and a correction slide rail mechanism 3. The support plate 1 is arranged on the on-site conveyor belt frame, and has a circular through-hole 11 in the middle for passing the tubular conveyor belt 4; the roller mechanism 2 is installed on the support plate 1, and is a plurality of groups arranged at intervals along the circumferential direction of the circular through-hole 11; the correction slide rail mechanism 3 is installed on the support plate 1, is arranged concentrically with the circular through-hole 11, and is located on the inner ring of the roller mechanism 2.

[0035] Preferably, there are six groups of roller mechanisms 2. The roller mechanisms 2 are evenly distributed on the support plate 1 through bolt connection to form support for the tubular conveyor belt 4.

[0036] The roller mechanism 2 includes a fixed frame 21, a swing connection assembly 22, a roller frame 23, a roller 24, and two rollers 25. The fixed frame 21 is mounted on the support plate 1, and the roller frame 23 is movably mounted on the fixed frame 21 through the swing connection assembly 22 and faces radially inward. Preferably, the swing connection assembly 22 includes a movable connecting pin 221 and a bearing 222 mounted on the movable connecting pin 221.

[0037] The ends of the rollers 24 are rotatably mounted on the roller frame 23. Their outer working surfaces are concave, curved rubber surfaces. The rollers 24 support the outer periphery of the tubular conveyor belt 4. The concave, curved rubber surfaces better conform to the surface of the tubular conveyor belt 4 and increase the friction between the tubular conveyor belt 4 and the rollers 24. Rollers 25 are mounted on the side of the roller frame 23 facing the support plate 1, with two rollers 25 symmetrically distributed on either side of the center plane of the swing connection assembly 22.

[0038] The guide rail mechanism 3 includes a fixed plate assembly 31, a guide roller 32, and a guide rail assembly 33. Both the fixed plate assembly 31 and the guide rail assembly 33 are coaxially arranged with respect to the circular opening 11. The fixed plate assembly 31 is fixed to the support plate 1 and is provided with an axially protruding annular guide rail 311 and a stop pin 312. The guide roller 32 is mounted on the side of the guide rail assembly 33 facing the fixed plate assembly 31 and engages with the annular guide rail 311.

[0039] Preferably, the fixed plate assembly 31 is composed of two semicircular fixed plates, which are connected to the support plate 1 of the tubular conveyor belt 4 by bolts. The outer periphery of the protruding annular guide rail 311 on the fixed plate assembly can clamp the guide roller 32 installed with the slide rail assembly 33.

[0040] The slide rail assembly 33 defines an elongated arcuate hole 331 corresponding to the stop pin 312. Preferably, the arc of the elongated arcuate hole 331 is π / 18-π / 9. The stop pin 312 is mounted in conjunction with the elongated arcuate hole 331 and can swing within the elongated arcuate hole 331. The axially outer end surface of the slide rail assembly 33 is provided with multiple concave arcuate surfaces 332 corresponding to the roller mechanism 2. The rollers 25 of the roller mechanism 2 abut against the concave arcuate surfaces 332 of the slide rail assembly 33.

[0041] The slide rail assembly 33 is connected to the limit pin 312 of the fixed plate assembly 31 through the long arc hole 331, and can realize a small angle of central rotation. The concave arc surface 332 of the curved track surface contacts the roller 25 of the roller mechanism 2. When the tubular conveyor belt 4 deviates, the friction between the tubular conveyor belt 4 and the roller 24 will cause the roller 24 to deflect in the running direction of the tubular conveyor belt 4. Because the roller 25 at the bottom of the roller mechanism contacts the slide rail assembly 33, the roller 24 will drive the slide rail assembly 33 to rotate in the center, forcing the six groups of roller mechanisms 2 to swing synchronously, thereby generating a lateral corrective force on the conveyor belt.

[0042] In the preferred embodiment, the rail assembly 33 includes three arcuate rails 333 forming a circular ring and a locking connector 334 connecting two adjacent arcuate rails 333. The three arcuate rails 333 are bolted together by three locking connectors 334, and the guide roller 32 is bolted to the middle of each arcuate rail 333.

[0043] The automatic deviation-correcting device of the present invention determines the installation position according to the on-site working conditions, fixes the fixed plate assembly 31 on the support plate 1 of the conveyor belt frame 4, and then connects the slide rail assembly 33 with the fixed plate assembly 31 through the limit pin 312 and the long arc hole 331 in sequence, so that the guide roller 32 can slide on the annular guide rail 311 of the fixed plate assembly 31; then the roller mechanism 2 is installed at a suitable position of the support plate 1 to ensure effective contact between the roller and the tubular conveyor belt 4; the roller 25 at the bottom of the roller mechanism 2 ensures that it is in center contact with the concave arc surface 332 of the slide rail assembly 33.

[0044] When the tubular conveyor belt 4 deviates, it drives the idlers 24 to rotate. The rotation of the idlers 23 creates an angle with the direction of motion of the tubular conveyor belt 4, similar to tire steering. This allows the tubular conveyor belt 4 to move toward the weak side, the opposite direction of the deviation, thereby correcting the belt's deviation. Because the rollers 25 at the bottom of the idler frame 23 contact the slide rails, the six idlers 24 rotate synchronously, providing a uniform corrective force.

[0045] The specific embodiments in the present invention are merely explanations of the present invention, and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
