[0025] As Figures 1-3As shown, the utility model discloses an underground deviation protection testing device, including base 1, the surface of base 1 is equipped with the deviation prevention device 2 for preventing the deviation of belt operation, deviation prevention device 2 includes the support cylinder 201 fixed on the surface of base 1, support cylinder 201 is fixedly installed on the surface of base 1, support cylinder 201 is made of high-strength metal material, has good pressure resistance and deformation resistance, can work stably for a long time in the harsh environment of underground, the surface of base 1 is rotatably provided with the rotating rod 202, the end of rotating rod 202 away from base 1 is fixedly connected with the rotating plate 203, the outside of rotating rod 202 is equipped with torsion spring 204, one end of torsion spring 204 is fixedly connected with rotating plate 203, and the other end is stably connected with base 1, when the belt deviates to a large extent, the belt will contact the related components of deviation prevention device 2 and produce force, the force drives rotating plate 203 to rotate around rotating rod 202, and then compresses torsion spring 204, and torsion spring 204 stores elastic potential energy in the process of being compressed, when the deviation force of the belt disappears or reduces to a certain degree, torsion spring 204 releases the stored elastic potential energy, drives rotating plate 203 to reverse rotation, thereby driving the components connected therewith to correct the belt, so that it returns to the normal running track, and the elastic coefficient of torsion spring 204 is carefully designed and calculated, can provide appropriate restoring force according to different belt specifications and common deviation force, and ensure the correction effect of belt deviation.

[0026] As Figures 1-3 As shown, the surface of rotating plate 203 is rotatably provided with first rolling component 205, in the application, first rolling component 205 is specifically rotating roller, rotating roller is installed on rotating plate 203 through the bearing at both ends, can rotate freely under the drive of the belt, when the belt runs, the bottom thereof contacts the surface of first rolling component 205, due to the rotating characteristics of first rolling component 205, the friction between the belt and first rolling component 205 is greatly reduced, the wear degree of the belt is effectively reduced, and the service life of the belt is prolonged, simultaneously, first rolling component 205 also plays a preliminary supporting and guiding role in the belt running process, helps to maintain the stable state of the belt in the initial normal operation period, and it is worth mentioning that the surface of first rolling component 205 is provided with a special wear-resistant layer, the wear-resistant layer adopts wear-resistant materials and surface treatment processes, such as tungsten carbide coating or hardfacing wear-resistant alloy, so that it has excellent wear resistance, can work stably for a long time in the high-wear environment of underground, and greatly improves the reliability and durability of first rolling component 205.

[0027] As Figures 1-3As shown, the rotating plate 203 is fixedly connected with a support 206, and the outer side wall of the connecting rod 207 is provided with a threaded groove 215.

The position of the connecting rod 207 on the support 206 can be flexibly adjusted and accurately fixed according to actual working requirements. In the actual production process in the coal mine, different belt widths and material loading requirements require that the loading depth of the belt can be adjusted accordingly. By loosening the bolt, the operator can slide the connecting rod 207 upward or downward along the support 206. When adjusted to the appropriate position, the bolt is tightened again to fix the connecting rod 207 at the new position. For example, when it is necessary to increase the depth of the belt to load coal or ore, the connecting rod 207 is slid upward. At this time, the positions of the related components connected with the connecting rod 207 are also raised, so that the belt can load more materials during operation.
