Description

Technical Field

[0001] This utility model relates to the field of belt technology, specifically a belt replacement and traction reversing device. Background Technology

[0002] A belt conveyor is a friction-driven machine that transports materials continuously. It mainly consists of a frame, conveyor belt, idlers, drums, tensioning devices, and a transmission system. It can transport materials along a defined conveyor line from the initial feeding point to the final unloading point, forming a material transport process. It has advantages such as large conveying capacity, simple structure, convenient maintenance, and standardized components, and is widely used in mining, metallurgy, and coal industries.

[0003] Extensive searches revealed that Chinese Utility Model Patent Publication No. CN214248188 discloses a traction belt replacement device, comprising a first support frame, a second support frame, a double-ended connecting screw, a left-side transmission screw, and a circular connecting rod. The double-ended connecting screw is internally connected to the first support frame, and the other end of the double-ended connecting screw is connected to the second support frame. The upper part of the first support frame is provided with a first rotating shaft and a left-side transmission screw, and the upper part of the left-side transmission screw is connected to a left-side moving block. The upper part of the second support frame is provided with a second rotating shaft and a right-side transmission screw, and the upper part of the right-side transmission screw is connected to a right-side moving block. A circular connecting rod is provided in the middle of the left-side moving block and the right-side moving block.

[0004] During long-term, high-frequency use, belt conveyors will experience severe belt wear, necessitating regular replacement. Due to limitations imposed by other equipment and site conditions, and the need for belt rerouting between old and new belts, some belt rerouting utilizes idler rollers. However, for long belts, high lifting heights, or large rerouting angles, idler rollers provide insufficient rerouting force and are not securely fixed during belt replacement. To effectively reroute and pull the belt, a belt replacement traction and rerouting device is designed. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a belt replacement traction reversing device, including a platform 1, a one-way screw 5 rotatably mounted on the upper part of the platform 1, a support frame 2 slidably mounted on the outer side of the one-way screw 5, the support frame 2 sliding on the upper part of the platform 1, a reversing component 3 rotatably mounted on the upper part of the platform 1, a slider 4 rotatably mounted on the top of the reversing component 3 through a bearing seat, the slider 4 sliding on one side of the support frame 2, and the horizontal cross section of the slider 4 is a convex-shaped structure.

[0028] like Figure 1 and Figure 4 As shown, a bidirectional screw 6 is rotatably mounted on the upper part of the platform 1. Two first sleeve plates 7 are symmetrically arranged and threaded on the outer side of the bidirectional screw 6. An inclined rod 8 is rotatably mounted on the upper part of each of the two first sleeve plates 7. The two inclined rods 8 are staggered and the top of each of the two inclined rods 8 is rotatably connected to a second sleeve plate 10. A lower adjustment component 9 is integrally arranged between the two second sleeve plates 10. The outer side of the bidirectional screw 6 is provided with external threads that are symmetrically arranged. The two first sleeve plates 7 are respectively threaded onto the two external threads in the bidirectional screw 6.

[0029] The height of the lower adjusting roller 902 is adjusted according to issues such as belt adjustment height or length. By rotating the bidirectional screw 6, the two first sleeve plates 7 are driven to move closer or further apart. The first sleeve plates 7 then use the tilting rod 8 to drive the lower adjusting assembly 9 to rise and fall.

[0030] like Figure 1 - Figure 3As shown, the redirection assembly 3 includes a redirection bracket 301, and a redirection roller 302 is rotatably disposed on one side of the redirection bracket 301;

[0031] The redirecting drum 302 ensures the reliability of the redirecting device, and the bearing housing makes the drum rotate more flexibly under large lateral forces, and the bearing can withstand greater forces.

[0032] like Figure 1 and Figure 4 As shown, the lower adjustment assembly 9 includes a roller frame 901, and a lower adjustment roller 902 is rotatably mounted on the upper part of the roller frame 901. The lower adjustment roller 902 is located on one side of the redirecting roller 302 and is horizontally positioned.

[0033] As the belt will sink due to its own weight during the belt traction process, and the old belt has poor support and tends to accumulate at the bottom of the drum, the lower adjusting roller 902 can effectively support the belt, so that the belt fits on the redirecting drum 302 as a whole, ensuring that the belt does not get stuck in the lower bearing seat during the traction process and ensuring that the traction friction is small.

[0034] like Figure 1 and Figure 6 As shown, the support frame 2 includes a support plate 201, a support vertical rod 202 is welded to the upper part of the support plate 201, two support diagonal rods 203 are welded between the support vertical rod 202 and the support plate 201, and a vertical groove 13 is opened on one side of the support vertical rod 202, and the slider 4 slides in the cavity of the vertical groove 13.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, platform 1 includes a base plate 101. A first mounting plate 102 and a second mounting plate 103 are welded to the upper part of the base plate 101. The redirection bracket 301 and the one-way screw 5 are both mounted on the upper part of the first mounting plate 102 through bearing seats. The two-way screw 6 is mounted on the upper part of the second mounting plate 103 through bearing seats. The upper parts of the first mounting plate 102 and the second mounting plate 103 are provided with through-hole fixing holes. Bolts are inserted into the fixing holes. Threaded grooves are provided on the upper part of the base plate 101 at the corresponding positions of each fixing hole. The bottom end of each bolt is threaded into the cavity of each threaded groove. The base plate 101 is placed on the ground, and the bottom of the base plate 101 is patterned.

[0036] The patterned design on the bottom of the base plate 101 increases the friction with the ground. If there are other steel structures or concrete foundations in the belt replacement area, the base plate 101 can be fixed by expansion bolts or welding to further improve the overall stability.

[0037] Bolts can increase the stability of the mutual fixation between the first mounting plate 102 and the base plate 101, and between the second mounting plate 103 and the base plate 101.

[0038] like Figure 1 As shown, two placement frames 11 are welded to the upper part of the base plate 101, and counterweights 12 are placed inside the placement frames 11.

[0039] The counterweight 12 is placed on the base plate 101. The weight of the counterweight can be increased or decreased as appropriate according to the specific conditions of the belt to increase the friction between the base plate 101 and the ground.

[0040] like Figure 1 , Figure 5 and Figure 6 As shown, the first mounting plate 102 is integrally formed with a track rod 15, and the support plate 201 has a track groove at the corresponding position of the track rod 15. The track rod 15 slides in the cavity of the track groove. The track rod 15 includes two L-plates arranged in mirror symmetry, and a convex cavity is formed between the two L-plates. The track groove includes two L-shaped cavities arranged in mirror symmetry.

[0041] like Figure 1 As shown, two servo motors 14 are mounted on the base plate 101. The output shafts of the two servo motors 14 are fixedly connected to the ends of the unidirectional screw 5 and the bidirectional screw 6, respectively. The servo motors 14 are electrically connected to the power supply.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
