[0004] To this end, the present application provides a belt conveyor roller replacement auxiliary tool. The belt conveyor includes a conveying belt, a plurality of rollers, and two parallel trusses. The plurality of rollers are located below the trusses and are used to support the conveying belt. A first connecting rod is vertically connected to two second connecting rods. The end of the second connecting rod is vertically connected to a lap rod, and the two lap rods are oppositely arranged. The distance between the two second connecting rods is greater than or equal to the sum of the distance between the two truss rods and the width of the two truss rods. The sum of the length of the second connecting rod and the thickness of the first connecting rod is less than the distance from the top surface of the truss rod to the top surface of the roller.

[0005] Preferably, the end of the first connecting rod is fixed with a handle.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical scheme and advantages of the application more clear, the application will be further described in detail below in combination with the drawings and embodiments.

[0015] As Figure 1 , Figure 2As shown, the belt conveyor can be a general belt conveyor in this technical field. The belt conveyor includes a frame, which includes columns 11 that stand upright on the ground. A truss is fixed on the columns 11. The truss includes two horizontally arranged truss rods 12 with equal heights. Rollers are provided at both ends of the truss, and a conveyor belt 13 is connected between the two rollers. The two rollers can drive the conveyor belt 13 to rotate. The belt conveyor also includes multiple idlers 14 located below the truss and spaced equally. The portion of the conveyor belt 13 that drives the transmission below the truss is located above the multiple idlers 14, and the multiple idlers 14 can support the conveyor belt 13.

[0016] The idler roller 14 can be mounted on the column 11, and there are no specific restrictions. Since the part of the conveyor belt 13 that drives under the truss is located above the idler roller 14, the conveyor belt 13 is pressed tightly against the idler roller 14. Therefore, it is inconvenient to disassemble and replace the idler roller 14.

[0017] Currently, when disassembling and replacing idler roller 14, two operators are required to first lift the conveyor belt 13 so that the bottom surface of the conveyor belt 13 is detached from the idler roller 14, so that the idler roller 14 can be disassembled and replaced in the next step. The above method is time-consuming and labor-intensive, and the disassembly and replacement efficiency of idler roller 14 is low.

[0018] like Figure 3 , Figure 4 As shown, this application provides an auxiliary tool for replacing idler rollers of a belt conveyor. The auxiliary tool is used to assist in the replacement and disassembly of idler rollers of a belt conveyor. It is convenient, quick, time-saving, labor-saving, safe and efficient, and can improve the efficiency of disassembly and replacement of idler roller 14.

[0019] The auxiliary tool is integrated into one piece, which makes the auxiliary tool structure stable and reliable, and has a long service life.

[0020] Auxiliary tools can be integrally formed through processing techniques, such as welding, without specific limitations.

[0021] The auxiliary tool includes a first connecting rod 21, on which two second connecting rods 22 are vertically connected; the ends of the second connecting rods 22 are vertically connected to overlapping rods 23, and the two overlapping rods 23 are arranged facing each other.

[0022] The distance A between the two second connecting rods 22 (e.g.) Figure 3 (As shown) is greater than or equal to the sum of the spacing between the two truss members 12 and the width of the two truss members 12, a (as shown) Figure 2 (As shown).

[0023] The sum B of the length of the second connecting rod 12 and the thickness of the first connecting rod 11 (e.g., ...) Figure 3 (As shown) The distance b between the top surface of truss rod 12 and the top surface of roller 14 is less than the distance b between the top surface of truss rod 12 and roller 14.Figure 2 The length D (as shown in the figure) of the overlapping rod 23 is greater than or equal to the width d (as shown in the figure) of the top surface of the truss rod 12, so that the overlapping rod 23 can be completely overlapped on the top surface of the truss rod 12, and the first connecting rod 21 can stably and effectively support the lifting of the conveying belt 13.

[0024] The length D (as shown in the figure) of the overlapping rod 23 is greater than or equal to the width d (as shown in the figure) of the top surface of the truss rod 12, so that the overlapping rod 23 can be completely overlapped on the top surface of the truss rod 12, and the first connecting rod 21 can stably and effectively support the lifting of the conveying belt 13. Figure 3 The length D (as shown in the figure) of the overlapping rod 23 is greater than or equal to the width d (as shown in the figure) of the top surface of the truss rod 12, so that the overlapping rod 23 can be completely overlapped on the top surface of the truss rod 12, and the first connecting rod 21 can stably and effectively support the lifting of the conveying belt 13. Figure 2 The length D (as shown in the figure) of the overlapping rod 23 is greater than or equal to the width d (as shown in the figure) of the top surface of the truss rod 12, so that the overlapping rod 23 can be completely overlapped on the top surface of the truss rod 12, and the first connecting rod 21 can stably and effectively support the lifting of the conveying belt 13.

[0025] The end of the first connecting rod 21 is fixed with a handle 24, and the operator can conveniently use the auxiliary tool by holding the handle 24.

[0026] A wear-resistant pad (not shown in the figure) is sleeved on the handle 24, and the material of the wear-resistant pad can be soft glue, which is not limited here. By providing the wear-resistant pad, the friction between the operator's hand and the handle 24 can be improved, and the use of the auxiliary tool is more convenient.

[0027] The end of the overlapping rod 23 is vertically connected with a limiting rod 25, and the limiting rod 25 extends towards the first connecting rod 21. The limiting rod 25 can limit the overlapping rod 23, so that the overlapping rod 23 can be stably and effectively overlapped on the top surface of the truss rod 12.

[0028] The application also provides a use method of the auxiliary tool for replacing the belt conveyor roller, which comprises the following steps: The auxiliary tool is inserted into the truss below, and the auxiliary tool is moved upwards, so that the first connecting rod 21 abuts against the bottom surface of the conveying belt 13, and the two overlapping rods 23 are respectively overlapped on the top surfaces of the two truss rods 12.

[0029] The sum B of the length of the second connecting rod 12 and the thickness of the first connecting rod 11 is less than the distance b from the top surface of the truss rod 12 to the top surface of the roller 14, so that when the overlapping rod 23 is overlapped on the truss rod 12, the first connecting rod 21 can lift the conveying belt 13, so that the bottom surface of the conveying belt 13 can be separated from the top surface of the roller 14, and the conveying belt 13 and the roller 14 are prevented from being in contact; so as to increase the operation space around the roller 13, and then the disassembly and replacement of the roller 13 can be conveniently realized.

[0030] The overlapping rod 23 has an overlapping surface (not shown in the figure) overlapped with the top surface of the truss rod 21, and the overlapping surface is provided with an anti-skid layer. By providing the anti-skid layer, the friction between the overlapping surface of the overlapping rod 23 and the top surface of the truss rod 21 can be increased, so that the overlapping rod 23 can be stably and effectively overlapped on the top surface of the truss rod 21.

[0031] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the present application; although the present application has been described in detail with reference to the foregoing examples, the technical solutions recorded in the foregoing examples can still be modified by those of ordinary skill in the art, or some technical features thereof can be replaced by equivalent replacements; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
