[0002] In the process of transporting bulk materials, belt conveyors are used to load and unload the bulk materials. However, after long-term use, the conveyor belts often suffer from various damages such as tearing, cracking, and holes, which reduces the conveying performance of the belts.

[0003] Generally, a vulcanizer is used to repair damaged conveyor belts. However, conventional vulcanizers are composed of aluminum I-beams, tension bolts, vulcanizing plates, hydraulic plates, presses and control boxes. They have many parts and are heavy, making them inconvenient to carry. They also have complex structures and cumbersome operations. They require the belts to be disassembled, and their operating efficiency is low. They are not suitable for high-frequency, small-damage conveyor belt repair operations.

[0004] The specification of Chinese patent CN216099971U discloses a fixing clamp for belt vulcanization repair. The utility model can flexibly adjust the clamping force of the upper pressure plate and the lower pressure plate by adjusting the screw-in amount of the adjusting bolt. It has a simple structure, light weight, and is easy to carry and use. When repairing the belt, there is no need to remove the roller or support, and the damaged part of the belt can be repaired directly, with high operating efficiency.

[0005] However, in actual application, due to the different widths of the conveyor belts and the fixed length of the bracket of the above-mentioned repair device, it is not easy to repair the damaged part near the center of the conveyor belt. As a result, when repairing, different types of repair devices need to be used for damaged parts in different positions, which increases the maintenance cost and requires frequent replacement, which is inconvenient for staff to use.

[0008] In the above-mentioned bulk material transportation system maintenance equipment, the length of the bracket can be changed, so that damaged parts at different positions on the surface of conveyor belts of different widths can be repaired, which is convenient for use by staff.

[0009] As a further improvement of the present application, two scale plates are fixedly connected to the front end of the U-shaped frame, and a plurality of scale lines are provided on the surface of the scale plates, and the plurality of scale lines are located directly in front of the plurality of fixing holes.

[0027] Figure 2 and Figure 3 It is shown that: both upper and lower ends of the left surface of the U-shaped frame 5 are provided with slide grooves 6, the slide groove 6 and the extension rod 7 are T-shaped, and the narrower ends of the two slide grooves 6 correspond to each other, so as to effectively prevent the extension rod 7 from falling, and the upper and lower left ends of the U-shaped frame 5 are fixedly connected with fixing boxes 9, and the front end of the U-shaped frame 5 is fixedly connected with two scale plates 16, and a plurality of scale lines are provided on the surface of the scale plate 16, and the plurality of scale lines are located directly in front of the plurality of fixing holes 8, and the scale lines are located in front of the fixing holes 8, so that the staff can observe the moving distance of the extension rod 7 and adjust the upper and lower extension rods 7 conveniently.

[0028] Figure 4 It is shown that: an extension rod 7 is provided in the slide groove 6, and a plurality of fixing holes 8 are penetrated at the corresponding ends of the two extension rods 7. The plurality of fixing holes 8 are convenient for fixing the extension rods 7. A slide plate 10 is provided in the fixing box 9, and a pull rod 11 is penetrated at the ends of the two fixing boxes 9 that are away from each other. The corresponding ends of the two pull rods 11 penetrate the fixing box 9, the slide plate 10, the U-shaped frame 5 and the fixing holes 8 in sequence. A spring 12 is provided on the outer ring of the pull rod 11. The extension and retraction of the spring 12 facilitates the movement and reset of the pull rod 11. The two ends of the spring 12 are fixedly connected to the slide plate 10 and the inner wall of the fixing box 9 respectively.

[0029] Figure 5 and Figure 6It is shown that: the left end of the extension rod 7 is fixedly connected with a positioning block 13, and the upper end of the positioning block 13 located above is penetrated by a cylinder 20. Technical personnel in this field can select a suitable type of cylinder 20 according to actual needs, for example: SCD50x100-100-LB. The cylinder 20 can adjust the height of the heating plate 15 located above, so as to adapt to conveyor belts of different thicknesses. The cylinder 20 is fixedly connected with a mounting block 2 14 at one end corresponding to the positioning block 13 located below, and the heating plate 15 is rotatably connected at one end of the two mounting blocks 2 14. The corresponding ends of the two extension rods 7 are fixedly connected with an indicator bar 17, which moves along with the movement of the extension rod 7 and is used in conjunction with the scale line for easy use by the staff. The lower surface of the indicator bar 17 is in contact with the inner wall of the U-shaped frame 5, and the indicator bar 17 is located at the right end of the fixing hole 8 at the far right.

[0030] When in use, the height of the equipment is adjusted by the electric push rod 2, and then the equipment is pushed so that the conveyor belt is located in the U-shaped frame 5, and the heating plate 15 at the lower end is in contact with the lower surface of the conveyor belt. Then the pull rod 11 is pulled to shrink the spring 12, and the pull rod 11 moves downward to disengage from the fixing hole 8. Then the positioning block 13 is pulled to the left to move the extension rod 7 to the left to an appropriate position, and then the pull rod 11 is released to pass through the fixing hole 8, thereby fixing the extension rod 7. Finally, the cylinder 20 is started to extend, so that the heating plate 15 at the upper end moves downward until it is in contact with the upper surface of the conveyor belt. The heating plate 15 is started to repair the damaged part of the conveyor belt, so that the equipment can directly repair the damaged parts at different positions on the surface of the conveyor belt without frequent replacement, thereby improving the repair efficiency and facilitating the use of the staff.

[0031] The second implementation method:

[0032] Based on the first embodiment, this embodiment adds a temperature sensor 18 and a controller 19, and the rest of the parts are consistent with the first embodiment.

[0033] Figure 7 It is shown that: the ends of the two heating plates 15 that are away from each other are fixedly connected with temperature sensors 18. Those skilled in the art can select a suitable type of temperature sensor 18 according to actual needs, such as WZP-231. The temperature sensor 18 can monitor the surface temperature of the heating plate 15 in real time, thereby effectively avoiding the surface temperature of the heating plate 15 from being too high or too low, and improving the repair efficiency. The front end of the fixed plate 3 is fixedly connected with a controller 19. Those skilled in the art can select a suitable type of controller 19 according to actual needs, such as: CM-D40. The heating plate 15 and the temperature sensor 18 are both electrically connected to the controller 19.

[0034] When in use, as the heating plate 15 continuously heats the conveyor belt, the temperature of the surface of the heating plate 15 continues to rise. At this time, the temperature of the surface of the heating plate 15 is monitored in real time by the temperature sensor 18 until the surface temperature of the heating plate 15 reaches 130 degrees, and the heating plate 15 stops heating. When the surface temperature of the heating plate 15 drops to 110 degrees, the heating plate 15 restarts, so that the surface temperature of the heating plate 15 is between 110 degrees and 130 degrees, thereby stably heating the conveyor belt and avoiding the temperature of the heating plate 15 being too high or too low, thereby affecting the repair efficiency of the conveyor belt.

[0035] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
