[0048] positioning assembly 5, positioning assembly 5 is welded on fixed frame 1, positioning assembly 5 is located at the back of diversion roller 4, and positioning assembly 5 is used to position belt to prevent position deviation of belt during conveying;

[0049] power component 6, power component 6 is installed on fixed frame 1 by bolt, power component 6 is located at the back of positioning assembly 5, and power component 6 is used to provide power outputted outward for belt;

[0050] bottom block 211 is fixed on mounting bracket 21, two groups of first hydraulic rods 231 are hinged on bottom block 211, and the piston rods of two groups of first hydraulic rods 231 are respectively connected with two groups of movable arms 23;

[0051] The two groups of side rollers 212 are mounted on the mounting frame 21 through bearings, and the two groups of supports 213 are fixed on the mounting frame 21, and the two groups of side rollers 2131 are mounted on the two groups of supports 213 through bearings, and the movable column 232 is movably arranged on the two groups of movable arms 23, and the movable disc 233 is movably connected to the movable column 232, and the clamping disc 234 is mounted on the movable disc 233 through bolts, and the transmission seat 235 is fixed on the two groups of movable arms 23, and the threaded rod 2321 is movably arranged in the transmission seat 235, and the threaded rod 2321 is fixedly connected to the movable column 232, and the worm gear is rotatably arranged in the transmission seat 235 and is threadedly connected to the threaded rod 2321, and the No. 1 motor 2351 is mounted on the transmission seat 235 through bolts, and the worm is fixed on the output shaft of the No. 1 motor 2351, and the worm on the output shaft of the No. 1 motor 2351 is engaged with the worm gear in the transmission seat 235.

[0052] When the old conveying belt needs to be processed, the hydraulic system is started to drive the two groups of No. 1 hydraulic rods 231 to start the extension and retraction operation, and the movable arms 23 will rotate around the rotating rod 221 on the mounting seat 22, so as to realize the position adjustment of the movable arms 23 in space. When the two groups of movable arms 23 are driven by the No. 1 hydraulic rods 231, the clamping discs 234 on the movable arms 23 reach the pre-set grabbing position for the old conveying belt, the corresponding No. 1 motor 2351 is started immediately, the worm fixed on the output shaft of the No. 1 motor 2351 is engaged with the worm gear in the transmission seat 235, under the drive of the No. 1 motor 2351, the worm drives the worm gear to rotate, and the worm gear is threadedly connected with the threaded rod 2321, so that the threaded rod 2321 moves axially in the transmission seat 235, so that the two groups of clamping discs 234 at the upper and lower ends of the movable arms 23 can move towards each other, so as to stably and firmly clamp the conveying belt located therebetween.

[0053] In summary, in the main inclined shaft belt conveyor belt replacement operation, the position of the two groups of movable arms 23 is adjusted by stretching and retracting the two groups of first hydraulic rods 231, and after the chuck 234 on the movable arm 23 reaches the designated position, the corresponding first motor 2351 is operated, and the transmission cooperation of the worm and the worm gear is used to clamp the conveying belt on the two groups of chucks 234 at the upper and lower ends of the movable arm 23. After that, the first hydraulic rod 231 is retracted, the movable arm 23 is moved to the right, and the conveying belt is moved to the right. In this way, it is convenient for the old conveying belt to be connected with the power assembly 6, and the problems of high labor intensity, low efficiency and insufficient accuracy in the previous belt replacement operation by relying on manpower to carry or pull the conveying belt are solved. The automatic traction is realized, and the efficiency and quality of the entire belt replacement operation are improved.

[0054] Example 2

[0055] It is found that although the conveying belt can be clamped and conveyed to the right by the taking component 2, the conveying belt is prone to sagging during conveying. To solve the above problem, the utility model of this embodiment is used.

[0056] Please refer to Figure 5 The supporting assembly 3 comprises a base frame 31, an arc groove plate 32 and a hinged seat 33. The base frame 31 is installed on the fixed frame 1 by bolts. The arc groove plate 32 is provided with two groups, and the two groups of arc groove plates 32 are fixed on the upper end of the base frame 31. The two groups of arc groove plates 32 are each provided with a movable plate 321 installed through a bearing. The two groups of movable plates 321 are each provided with a carrier roller 322 installed through a bearing. The carrier roller 322 moves in the arc groove on the two groups of arc groove plates 32. The hinged seat 33 is provided with two groups, and the two groups of hinged seats 33 are each installed on the left end of the base frame 31 by bolts.

[0057] The two groups of hinged seats 33 are each hinged with a second hydraulic rod 331. The piston rods of the two groups of second hydraulic rods 331 are respectively connected with the left ends of the two groups of movable plates 321 through pins.

[0058] The left ends of the two groups of arc groove plates 32 are each provided with an upper stop seat 323 and a lower stop seat 324. The upper stop seat 323 and the lower stop seat 324 are each provided with a waist-shaped through slot. A bolt is installed in the waist-shaped through slot, and the bolt is screwed on the arc groove plate 32.

[0059] On the basis of the above embodiment, when the main inclined shaft belt conveyor belt changing device is running, the carrier roller 322 plays a key supporting role, which is installed between the two groups of movable plates 321 and located in the arc groove of the arc groove plate 32, can closely fit the bottom of the conveyor belt, effectively disperse the weight of the conveyor belt, so as to prevent the conveyor belt from sagging due to its own gravity, and ensure the smooth running of the conveyor belt during belt changing. When the height of the carrier roller 322 needs to be adjusted, the telescopic No. 2 hydraulic rod 331 can be realized. The two ends of the No. 2 hydraulic rod 331 are respectively connected with the hinge seat 33 and the left end of the movable plate 321 through the pin shaft. When the hydraulic rod is telescopic, a pushing or pulling force is generated, which promotes the rotation of the two groups of movable plates 321 with the connecting bearing of the arc groove plate 32 as the shaft. With the change of the angle of the movable plate 321, the height of the carrier roller 322 also changes accordingly, further improving the adaptability and reliability of the belt changing device to various complex conditions, and ensuring the smooth progress of the belt changing operation.

[0060] In summary, during the belt changing process of the main inclined shaft belt conveyor, the carrier roller 322 can support the conveyor belt, and by virtue of its installation layout between the movable plates 321 and in the arc groove of the arc groove plate 32, it can effectively disperse the weight of the conveyor belt, prevent the conveyor belt from sagging, and ensure smooth running. At the same time, by means of the telescopic No. 2 hydraulic rod 331, the height of the carrier roller 322 is adjusted by pushing the movable plate 321 to rotate, so as to adapt to the height requirement of the conveyor belt under different working conditions.

[0061] Embodiment 3

[0062] On the basis of the above embodiment, it is found that although the conveyor belt does not sag during conveying, the position of the conveyor belt may deviate during conveying. Once the position of the conveyor belt deviates and is not corrected in time, as the degree of deviation gradually increases, the conveyor belt is likely to collide, rub or jam with other fixed parts or adjacent structures in the device. This situation not only causes the device to be instantly stuck, but also stops the entire belt conveyor system from running. To solve the above problem, the utility model of this embodiment is used.
