Description

Technical Field

[0001] The utility model relates to the field of general structural parts, in particular to a three-string roller removal device. Background Art

[0002] Three-string roller belt conveyors are widely used in the transportation link in coal mine production sections due to their technical advantages such as the belt is not easy to deviate and has a larger load capacity. However, the process of removing the rollers of this type of equipment is very cumbersome. The hanging grooves at both ends are different from straight rollers, and they cannot be directly lifted and replaced using crowbar-type equipment; the belt needs to be lifted up first to leave space for replacement, and then the rollers are lifted off the frame by manual lifting. During the construction process, it is very difficult to lift the belt itself, and there is a great risk of manual lifting of the rollers under this condition. There is currently a lack of specific solutions for the above situation. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a device with a simple structure and ingenious design. The device uses a belt frame tube body as a support basis and rotates a pull roller gripper to achieve roller removal operations without supporting the belt.

[0004] The device comprises a support tube, a connecting rod is arranged on the side of the support tube, and a support plate is arranged at the end of the connecting rod;

[0005] A chain is arranged at the lower part of the support tube, and a draw hook is arranged at the tail end of the chain.

[0006] The chain length mentioned here corresponds to the spacing between the roller gripper and the belt frame, that is, the frame tube body on the side of the belt conveyor; the effect achieved by this is to place the support plate on the belt frame, then hang the hook in the gripper at the end of the roller, rotate the support tube to tighten the chain, and continue to exert force to achieve the effect of pulling the roller gripper obliquely, that is, to make the roller detach from the frame and achieve removal.

[0007] The beneficial effects of the utility model are as follows: the utility model solves the problem of inconvenience in removing three strings of rollers in the prior art, realizes the removal of three strings of rollers without supporting the belt, and can greatly improve the work efficiency and work safety. In particular, the equipment has a simple structure, low construction and maintenance costs, and has great social promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0013] Reference Figure 1 , Figure 2 The three-string roller removal device of the utility model comprises a support tube 3, a connecting rod 2 is arranged on the side of the support tube 3, and a support plate 1 is arranged at the end of the connecting rod 2;

[0014] A chain 4 is arranged at the lower part of the support tube 3 , and a draw hook 5 is arranged at the tail end of the chain 4 .

[0015] The length of the chain 4 mentioned here corresponds to the spacing between the roller gripper and the belt frame, that is, the frame tube body on the side of the belt conveyor; the effect achieved by this is to place the support plate 1 on the belt frame, and then hang the hook 5 in the gripper at the end of the roller, rotate the support tube 3 to tighten the chain 4, and continue to exert force to achieve the effect of pulling the roller gripper obliquely, that is, to make the roller detach from the frame and achieve dismantling.

[0016] Example 1, refer to the accompanying drawings of the specification Figure 1 There are two connecting rods 2 in total, and the two connecting rods 2 are fixedly arranged on the support tube 3, and their arrangement form is relatively arranged.

[0017] Preferably, the length of the connecting rod 2, the length of the chain 4, and the spacing between the belt conveyor frame and the roller gripper correspond to each other, so as to achieve the effect of rotating the support tube 3 to tighten the chain 4 and continuing to rotate to pull out the gripper after the equipment is assembled.

[0018] Furthermore, the support plate 1 is a curved plate body, that is, the bottom surface of the support plate 1 is arranged in close contact with the frame pipe on the side of the belt conveyor.

[0019] Example 2, refer to the accompanying drawings of the specification Figure 2 There are two connecting rods 2 in total, and the two connecting rods 2 are hingedly arranged behind the support tube 3;

[0020] Positioning holes are correspondingly opened on the two connecting rods 2, and positioning bolts 7 are respectively inserted into the two positioning holes; the two positioning bolts 7 are inserted into the slide 6; the slide 6 is rectangular, and a slide groove is opened inside it, and the positioning bolts 7 are inserted into the slide groove, so as to realize the sliding connection between the positioning bolts 7 and the slide 6;

[0021] Positioning screw sleeves are also threadedly provided at the tail ends of the two positioning bolts 7 .

[0022] The effect achieved in this way is that the length of the chain 4 can be adapted by adjusting the expansion angle of the two connecting rods 2, so that after the assembly is completed, the support tube 3 can be rotated to tighten the chain 4 and the gripper can be further rotated to pull out.

[0023] Embodiment 3: A hanging ring is arranged in front of the support pipe 3, and the chain 4 is arranged in the hanging ring. The effect achieved by this is to avoid mutual interference of the components and facilitate construction.
