[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0024] like Figure 1 As shown in the figure, this specific embodiment provides an auxiliary tooling for replacing the idler rollers of a belt conveyor trough idler frame, including a support rod 3, a base 1, and a lifting drive component 2; the support end of the base 1 is provided with the lifting drive component 2, the lifting drive component 2 is connected to the support rod 3, the support rod 3 can lift the belt 4, and the lower part of the limiting end of the base 1 is provided with a connecting part, the connecting part is used to detachably connect with the cross brace 5 of the trough idler frame.

[0025] This specific embodiment uses the cross brace 5 of the trough roller frame as a support point for firm support, and the base 1 and the cross brace 5 of the trough roller frame can be detached and installed. Compared with the prior art, where the operator uses a pry bar to lift the belt 4, it is more labor-saving, safe, convenient and efficient.

[0026] like Figure 2As shown, to achieve a quick connection between the base 1 and the cross brace 5, in this specific embodiment, the connecting part has an L-shaped structure. The connecting part includes a connecting plate 102 and a snap-fit ​​plate 103. The length of the snap-fit ​​plate 103 is not less than the width of the cross brace 5, and the height of the connecting plate 102 is greater than the height of the cross brace 5 and less than the length of the hypotenuse of the cross brace 5. In use, the connecting part is inserted onto the cross brace 5 with the opening facing down and then rotated at a certain angle so that the snap-fit ​​plate 103 is located at the lower part of the cross brace 5 and the limiting end is located at the upper part of the cross brace 5 to achieve snap-fit. When the belt 4 is supported, the connecting end of the base 1 is subjected to a downward force, causing the connecting part to rotate around the cross brace 5 at a small angle. Since the height of the connecting plate 102 is less than the length of the hypotenuse of the cross brace 5, the base 1 is firmly snapped onto the cross brace 5. After use, it is removed by rotating in the opposite direction.

[0027] like Figure 2 As shown, in this specific embodiment, the lifting drive component 2 is a hydraulic cylinder; furthermore, to facilitate the storage of this tooling, a limiting groove 101 is provided on the upper surface of the support end, and the cylinder body of the hydraulic cylinder can be placed in the limiting groove 101. When in use, the hydraulic cylinder is subjected to force, and a small displacement is achieved by the limiting groove 101, thus abutting against the wall of the limiting groove 101. When not in use, the two can be directly separated and stored. Compared with the method of welding the hydraulic cylinder and the base 1, on the one hand, there is no welding cracking under stress, and on the other hand, it is easy to store.

[0028] In this specific embodiment, the support rod 3 is connected to the piston rod of the hydraulic cylinder by bolts.

[0029] Preferably, two lifting drive components 2 and two bases 1 are provided to enhance the support of the belt 4.

[0030] The method of using this tooling is as follows:

[0031] Attach base 1 to the relevant position on cross brace 5 and keep base 1 in a horizontal position; place hydraulic cylinder on base 1, drive support rod 3 to rise to a suitable position, and continuously lift belt 4 away from idler roller to replace idler roller; after replacement, retract hydraulic cylinder and remove base 1 from cross brace 5. Specific Implementation Method Two

[0033] like Figure 3 As shown, the structure of this specific embodiment is basically the same as that of the first specific embodiment, except that: the connecting part includes two connecting plates 102 arranged in a figure-eight shape, and a limit bolt 104 is vertically arranged on the connecting plate 102. The connecting plate 102 is parallel to the inclined surface of the corresponding cross brace 5, and the end of the limit bolt 104 can abut against the inclined surface of the cross brace 5.

[0034] In use, the limiting bolt is screwed to abut against the inclined surface of the cross support 5.

[0035] From the above specific embodiments, the utility model has the following beneficial effects:

[0036] 1. By firm support with the cross support 5 as support point, and the base 1 is detachably installed with the cross support 5 of the groove type carrier roller frame, compared with the crowbar lifting belt 4 in the prior art, it is more convenient to use;

[0037] 2. By setting the connecting part into L type, quick detachable connection is realized with the cross support 5 in the form of clamping, simple structure, reliable connection;

[0038] 3. By setting the limiting groove 101, the limiting effect of the hydraulic oil cylinder is realized to prevent the large angle skew from affecting the support after being stressed, and the fixed connection of the oil cylinder and the base 1 is not conducive to storage, and the connection position is easy to crack and fail after long-term use.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
