Description

Technical Field

[0001] The present application relates to the technical field of high-angle sidewall repair, and in particular to a high-angle sidewall repair device. Background Art

[0002] Steep-angle sidewall belts are specially designed conveyor belts for conveying bulk solids at steep angles. These conveyor belts are characterized by sidewalls (also called side panels or side guards) attached to either or both sides. These sidewalls are typically vulcanized integrally with the belt's rubber layer, forming a closed trough structure that effectively prevents material from sliding due to gravity during conveying. Steep-angle sidewall belts are primarily used in steep-angle sidewall belt conveyors, which are particularly suitable for conveying bulk solids vertically or at steep angles (typically greater than 20 degrees) within confined spaces.

[0003] Due to the particularity of the working environment and usage conditions, the base belt and skirt of the large-angle sidewall belt may crack during use, so regular repair and maintenance are required.

[0004] There are currently two solutions to the problem of cracking in high-angle sidewalls: one is to return the equipment to the factory for repair. This repair method can ensure the quality of the repair, but it will cause a long period of equipment downtime, seriously affecting production. Returning to the factory increases transportation costs, resulting in higher overall production costs; the other is that workers use special glue to bond the cracked area. This repair method can quickly repair the cracked base belt and skirt, but this method cannot guarantee the bonding quality. The base belt and skirt are likely to crack again in a short time, affecting production again. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will now be described in further detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0028] A maintenance device for a large-angle sidewall strip includes a frame 1, a flat jack 2 is vertically arranged in a fixed structural manner inside the frame 1, a mounting plate 3 is provided at the lower part of the output end of the flat jack 2 in a fixed structural manner, a linear slide rail 4 is provided on the lower end surface of the mounting plate 3 in a fixed structural manner, and the linear slide rail 4 is connected to a left slider 5 and a right slider 6 in a sliding structural manner; a left column 7 is provided on the lower end surface of the left slider 5 in a fixed structural manner, and a right column 8 is provided on the lower end surface of the right slider 6 in a fixed structural manner, the left column 7 and the right column 8 are connected to a driving mechanism 9 for driving the left column 7 and the right column 8 to move relative to or toward each other, a left clamp 10 and a right clamp 11 are respectively provided on the lower end surfaces of the left column 7 and the right column 8 in a fixed structural manner, and the left clamp 10 and the right clamp 11 are respectively connected to a heating plate.

[0029] The output shaft of the flat jack 2 extends to drive the left clamping jaw 10 and the right clamping jaw 11 to move downward. The left clamping jaw 10 and the right clamping jaw 11 move relative to each other through the driving mechanism 9 to clamp the skirt, and use the downward pressure to press the bottom of the skirt onto the base belt, and then the cracked base belt and the skirt are bonded through the vulcanization process to achieve a quick repair effect, avoid long-term return to the factory for repair, reduce maintenance costs, and improve overall production efficiency.

[0030] It should be noted that the frame 1 includes a U-shaped frame 12, a crossbeam 13 and a pad 14. The two U-shaped frames 12 arranged in parallel are connected by the crossbeam 13. The pad 14 is arranged on the inner wall of the U-shaped frame 12 at the bottom of the left clamping jaw 10 and the right clamping jaw 11 in a fixed structure manner; the flat jack 2 is fixedly arranged on the lower end face of the upper crossbeam 13. The design of this structure facilitates the placement of the large-angle retaining strip.

[0031] It should be noted that the left clamping jaw 10 includes a left fixed plate 101, and a tooth A is provided on the inner side of the left fixed plate 101; the right clamping jaw 11 includes a right fixed plate 111, and a tooth B is provided on the inner side of the right fixed plate 111 to engage with the tooth A so as to fit the structure of the skirt; the left fixed plate 101 and the right fixed plate 111 are both provided with a groove 15 for placing a heating plate, and the left fixed plate 101 and the right fixed plate 111 are directly heated by the heating plate to improve heat transfer and facilitate vulcanization and bonding of the lower end of the skirt to the base tape.

[0032] In one embodiment, the driving mechanism 9 includes a screw 91 and a nut 92. The two nuts 92 are connected to the screw 91 by threaded engagement. The screw 91 passes through the left column 7 and the right column 8, and the two nuts 92 are respectively located on the outside of the left column 7 and the right column 8. This structure facilitates driving the left and right columns, thereby adjusting the spacing between the left and right clamps, so that the clamps can better fit the skirt and baseband.

[0033] In another embodiment, the driving mechanism 9 includes a forward and reverse screw and a handwheel (not shown in the figure), the handwheel is connected to the forward and reverse screw in a fixed structure, the positive thread of the forward and reverse screw is connected to the left column 7 in a threaded engagement manner, and the reverse thread of the forward and reverse screw is connected to the right column 8 in a threaded engagement manner; compared with the above embodiment, this embodiment is easier to operate and will not cause wear of the forward and reverse screws.

[0034] Using one of the embodiments, the working principle and working process of the utility model are described as follows:

[0035] Place the high-angle sidewall strip on the backing plate 14. At this time, the skirt that needs to be repaired is located between the left clamping jaw 10 and the right clamping jaw 11. Then start the flat jack 2. The output shaft of the flat jack 2 extends, driving the mounting plate 3, linear slide 4, left slider 5, right slider 6, left column 7, right column 8, drive mechanism 9, left clamping jaw 10 and right clamping jaw 11 to move downward a certain distance. Turn the handwheel to engage the forward and reverse screws with the left column 7 and the right column 8, driving the left clamping jaw 10 and the right clamping jaw 11 to move relative to each other, so that the teeth A and B fit and clamp the lower part of the skirt.

[0036] After clamping, insert a heating plate into the embedding groove 15 and apply electricity to heat it. When the base belt and the skirt are in a molten state, start the flat jack 2 again. The flat jack 2 applies a downward pressure, which is transmitted to the base belt and the skirt through teeth A and B. When the pressure value of the flat jack 2 reaches the predetermined value, the output is stopped. Then the vulcanization process will bond the cracked base belt and the skirt. Stop heating and maintain the pressure until it cools naturally and solidifies into its original state.
