[0002] Belt conveyors are often used as important tools for transporting goods or materials in high-speed rail smelters. However, there are currently no good auxiliary tools when belt conveyors need to replace rollers in smelters. It takes 5 to 6 people to use crowbars to pry open the belt to remove the old rollers, making replacement particularly difficult. It takes at least 5 to 6 people more than 15 minutes to replace a roller.

[0027] Working and use process: When using the device to disassemble the belt conveyor roller, first install the crowbar 1 in the crowbar clamping assembly, turn on the stretching mechanism, and stretch the crowbar 1. Since the crowbar clamping assembly can cooperate with the stretching mechanism to adjust the angle of the crowbar 1 adaptively, the end of the crowbar 1 that contacts the belt conveyor roller can be lifted, thereby realizing the disassembly of the belt conveyor roller. Clamp the crowbar 1 in the crowbar clamping assembly, and cooperate with the stretching mechanism to adjust the angle of the crowbar 1. The crowbar clamping assembly provides a fulcrum for the crowbar 1. The end of the crowbar 1 away from the stretching mechanism contacts the belt conveyor roller, and the belt conveyor roller is tilted out. The crowbar clamping assembly is set to clamp the crowbar 1, and the stretching mechanism cooperates with the crowbar clamping assembly to lift the crowbar 1, thereby realizing the rapid disassembly of the belt conveyor roller. The device is easy to operate and saves time for disassembling the belt conveyor roller. It solves the problem that the belt conveyor rollers used in the existing high-speed rail smelting plant can only be replaced by multiple people in cooperation with manpower, the low replacement efficiency affects the production efficiency, and the manual replacement of the force point is large and damages the belt.

[0028] In some embodiments of the present invention, please combine Figure 2 and Figure 3 The crowbar clamping assembly includes a square fixed frame 2 fixedly connected to a support arm 8, the square fixed frame 2 is symmetrically provided with at least four hollow tubes 9 integrally formed with the square fixed frame 2, each of the hollow tubes 9 is provided with a limit block 10 extending into the square fixed frame 2, and each of the limit blocks 10 is connected to a telescopic assembly fixed to the bottom of the hollow tube 9 at one end away from the geometric center of the square fixed frame 2, and multiple limit blocks 10 are used to clamp the crowbar 1.

[0029] It can be understood that when the device is used to disassemble the belt conveyor roller, the crowbar clamping assembly cooperates with the stretching mechanism. When the stretching mechanism stretches the crowbar 1 downward, the limit block 10 moves in the hollow tube 9, and the angle of the crowbar 1 is adaptively adjusted, so that the crowbar clamping assembly cooperates with the stretching assembly to lift the end of the crowbar 1 close to the belt conveyor roller, thereby realizing the lifting and disassembly of the belt conveyor roller.

[0030] In some embodiments of the present invention, please continue to refer to Figure 3 The telescopic assembly includes a first motor 11 fixed to the bottom of the hollow tube 9, and a first telescopic rod 12 connected to the first motor 11, and one end of the first telescopic rod 12 away from the first motor 11 is fixedly connected to one end of the limit block 10 away from the geometric center of the square fixed frame 2.

[0031] It can be understood that when the first motor 11 is turned on, the first motor 11 drives the first telescopic rod 12 to extend, so that the limit block 10 moves toward the geometric center of the square fixed frame 2, and the first telescopic rod 12 of the limit block 10 opposite to this limit block 10 moves the relative limit block 10 away from the geometric center of the fixed frame, thereby realizing the adjustment of the angle of the crowbar 1.

[0032] In some embodiments of the present invention, please continue to refer to Figure 2 An elastic pad 13 is provided at the end of each limit block 10 located on the inner side of the square fixing frame 2.

[0033] It is understandable that the provision of the elastic pad 13 enables the limiting block 10 to fix the crowbar 1 more firmly.

[0034] In some embodiments of the present invention, the elastic pad 13 is preferably made of elastic rubber.

[0035] In some embodiments of the present invention, please refer to Figure 1 The stretching mechanism includes a second motor 4 fixed on the upper part of the load-bearing base 5, and a second telescopic rod 3 connected to the second motor 4. The second telescopic rod 3 is detachably connected to the lower part of the end of the crowbar 1 away from the prying point.

[0036] It is understandable that when the stretching mechanism is used, the second motor 4 is turned on, the second telescopic rod 3 is extended, and the end of the crowbar 1 away from the prying point is pushed up. The second motor 4 is driven, the second telescopic rod 3 is shortened, and the end of the crowbar 1 away from the prying point is shortened, so that the crowbar 1 can generate an upward prying force on the prying point, so that the crowbar 1 can remove the belt conveyor roller, and the angle adjustment of the crowbar 1 is achieved through the cooperation of the stretching mechanism and the crowbar clamping assembly.

[0037] In some embodiments of the present invention, please refer to Figure 6 The support arm 8 is hinged to the load-bearing base 5 by bolts. Such an arrangement enables the angle of the support arm 8 to be adjusted when necessary to meet different usage environments.

[0038] In some embodiments of the present invention, please continue to refer to Figure 1 A height adjustment mechanism is provided at the lower part of the load-bearing base 5.

[0039] In some embodiments of the present invention, please continue to refer to Figure 1 The height adjustment mechanism includes a hydraulic rod 7 and a hydraulic cylinder 6 connected to the hydraulic rod 7.

[0040] It can be understood that by turning on the hydraulic cylinder 6, the hydraulic rod 7 can be extended or shortened, and the load-bearing base 5 can be raised and lowered, so that in actual use, the angle of the load-bearing base 5 can be adjusted as needed, thereby adjusting the angle of the crowbar 1, so that the device can be applied to the replacement of different belt rollers, making the device have a wide range of applications.
