[0024] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] Embodiment 1, a bucket lifting belt connecting device, comprises: a pressing plate 2 and a steel wire rope 3.

[0027] Specifically, the pressing plates 2 are arranged in groups of two, and the two pressing plates 2 are fixedly connected by a "U"-shaped connecting frame 21, such as Figure 1 and Figure 2 As shown, the connecting frame 21 itself can be bent and deformed to a certain extent, so that the two pressure plates 2 can approach each other and realize the compression of the belt. The two pressure plates 2 are pressed on the surfaces of both sides of the belt respectively. The outer side of the connecting frame 21 is rotatably connected with the adjusting frame 1, and the cross-section of the adjusting frame 1 is in a "U" shape that is symmetrical with the connecting frame 21. When the pressure plate 2 of the device is connected to the belt, since the widths of the pressure plate 2 and the adjusting frame 1 are relatively small, and the pressure plate 2 and the adjusting frame 1 can rotate relative to each other, they can adapt to the bending deformation of the belt during transportation. A plurality of fixing pins 12 distributed at equal intervals are fixedly connected to the inside of the adjusting frame 1 on the side away from the connecting frame 21. The adjusting frame 1 and the pressure plate 2 are each provided with two groups, and are symmetrically distributed. When the device is used, the two pressure plates 2 are fixedly connected to the belts on both sides of the fracture respectively.

[0028] Secondly, the steel wire rope 3 is arranged in an "S" shape through the outside of a plurality of fixing pins 12 on the two sets of adjustment frames 1, and the two adjustment frames 1 are connected together, such as Figure 3 As shown, the device can change the distance between the two adjustment frames 1 according to the width of the belt break, so that it has a larger scope of application. Since the steel wire rope 3 is a complete one, each position thereof is subjected to uniform force, which can effectively avoid breakage caused by excessive local force. The end of the steel wire rope 3 is bent once and then fastened and fixed by a rope buckle 5. The rope buckle 5 is an existing known structure and will not be described in detail here.

[0029] In order to improve the connection strength between the two pressing plates 2, the present application provides multiple connecting frames 21, which are evenly spaced along the length direction of the pressing plate 2, which can effectively improve the connection strength between the two pressing plates 2, reduce the force of a single connecting frame 21, and extend the service life. A plurality of notched grooves 11 with equal spacing are provided on one side of the adjusting frame 1 close to the pressing plate 2. The connecting frame 21 is inserted into the notched grooves 11 and is rotatably connected to the adjusting frame 1 through the connecting shaft 4. Both ends of the connecting shaft 4 are fixedly connected to the limiting blocks 41, such as Figure 2 As shown, the pressure plate 2 and the adjustment frame 1 can both rotate around the connecting shaft 4 at a certain angle without blocking each other. After the device completes the belt repair and connection, the repaired position of the belt still has a bending function and will not affect the normal transportation of the belt.

[0030] In order to connect the pressure plate 2 with the belt, the two pressure plates 2 of the present application are kept fixedly connected by fastening bolts 22 and the belt is pressed. A friction pattern is provided on the side of the pressure plate 2 that is in contact with the belt to increase the friction between the pressure plate 2 and the belt. Before installing the device, the belt on both sides of the break position is first punched, and then the two pressure plates 2 are pressed against the two side surfaces of the belt respectively by fastening bolts 22. Finally, the wire rope 3 is passed between the two adjusting frames 1 and the adjusting frames 1 are connected.

[0031] In order to adjust the spacing between the two adjustment frames 1, the present application also has an annular sleeve 121 provided on the outer side of the fixed pin 12, and movable pins 13 are rotatably installed at both ends of the adjustment frame 1, and the movable pins 13 penetrate the adjustment frame 1, and the two ends of the wire rope 3 are buckled on the outer sides of the two movable pins 13, such as Figure 4 and Figure 3 As shown, the provision of the annular sleeve 121 enables the steel wire rope 3 to still be pulled after being inserted, so as to adjust the distance between the two adjustment frames 1 and avoid belt loosening.

[0032] In order to tighten the belt, the present application also has nuts 132 fixedly connected to both ends of the movable pin 13, and the nuts 132 are in contact with the surface of the adjustment frame 1. The setting of the nuts 132 allows the movable pin 13 to only rotate without being separated from the adjustment frame 1. An outer cylinder 131 is fixedly installed on the outer side of the middle of the movable pin 13. The middle of the outer cylinder 131 is concave to form an annular groove. The inner wall of the outer cylinder 131 is provided with friction lines. When the end of the wire rope 3 is wound around the outer cylinder 131, first use One rope buckle 5 fastens one end of the wire rope 3, and the other rope buckle 5 remains loosened. At this time, the wire rope 3 is pulled to tighten the wire rope 3, and the nut 132 is turned to drive the outer cylinder 131 to rotate. The outer cylinder 131 can further tighten the wire rope 3 through the friction between the wire rope 3, thereby further reducing the distance between the two adjustment frames 1 and tightening the belt. Finally, tightening the nut on the rope buckle 5 can prevent the wire rope 3 from loosening, and then prevent the belt from loosening.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
