DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figures 1 to 3 As shown, the present embodiment discloses a belt conveyor body, including an intermediate frame 1, on which a plurality of suspension devices for suspending an upper roller assembly 2 are arranged, each suspension device group includes two hooks 3, and the hooks 3 have two first hooking grooves 31 and a second hooking groove 32 arranged side by side, wherein one of the first hooking grooves 31 is used for normal suspension of the upper roller assembly 2, the other first hooking groove 31 is used for position adjustment of the upper roller assembly 2, and the second hooking groove 32 is used for disassembly, assembly and maintenance of the upper roller assembly 2.

[0024] The belt conveyor body in this embodiment effectively solves the problem that the upper roller assembly 2 cannot be adjusted and is inconvenient to disassemble and assemble by arranging two first hooking grooves 31 and one second hooking groove 32 on the hook 3. The structure is simple and reasonable, and the performance is greatly improved.

[0025] The hook 3 in this embodiment is formed by bending a round steel, and the depth of the second hook groove 32 is greater than the depth of the first hook groove 31. Compared with the traditional cast hook, the hook 3 in this embodiment has a simple structure, and the hook 3 made of round steel greatly improves the strength and rigidity, and improves the overall performance of the belt conveyor body, and the depth of the second hook groove 32 is designed to be greater than the depth of the first hook groove 31, which greatly facilitates the disassembly, assembly and maintenance of the upper roller assembly 2.

[0026] The intermediate frame 1 in this embodiment includes two support frames, which include a suspension beam 11 and two legs 12 vertically arranged on the suspension beam 11. The two hooks 3 of the suspension device are respectively arranged on the suspension beams 11 of the two support frames. The legs 12 of the two support frames correspond to each other one by one, and the corresponding legs 12 of the two support frames are connected by a connecting beam 13.

[0027] Specifically, the suspension beam 11 adopts a rectangular steel tube. Compared with the traditional 45° inclined groove steel suspension beam, the rectangular steel tube suspension beam 11 makes the support leg 12 as a whole only bear force in the vertical direction and no longer bear force in the horizontal direction, which solves the force problem of the support leg 12 and improves the supporting strength. In addition, the rectangular steel tube is light in weight, which reduces the weight of the whole machine and saves costs.

[0028] The legs 12 are made of I-beams. Compared with traditional channel steel and angle steel legs, the I-beam legs 12 can effectively solve the stress problem of the channel steel and angle steel legs being unable to withstand bending, and greatly improve the supporting strength of the legs 12.

[0029] Connecting beam 13 adopts Steel pipe, compared with the traditional channel steel and angle steel connecting beam 13, The connecting beam 13 of the steel pipe not only improves the connection strength, but also reduces the weight and saves the cost.

[0030] In this embodiment, the legs 12 of the two support frames are respectively provided with a quick disassembly device for installing the lower roller assembly 4. Such arrangement facilitates the quick disassembly and assembly of the lower roller assembly 4 and improves work efficiency.

[0031] Specifically, the quick disassembly and assembly device includes a fixed plate 5 arranged on the supporting leg 12, and a limiting plate 6 for limiting the chain of the lower roller assembly 4. The fixed plate 5 is provided with a through hole 51 for the chain of the lower roller assembly 4 to pass through, and the limiting plate 6 is provided with a vertical slot 61 adapted to the vertical ring of the chain. The chain in this embodiment is a ring chain. When in use, the chain as a whole passes through the through hole 51, and the vertical slot 61 of the limiting plate 6 is aligned with the vertical ring of the chain and inserted into the chain. The installation of the lower roller assembly 4 is realized by the limiting plate 6 and the horizontal ring of the chain cooperating with each other to limit. The structure is simple, convenient and flexible to use, and greatly improves the efficiency of disassembly and assembly.

[0032] In order to solve the problems of cable confusion and cable protection on site, in this embodiment, cable trays 7 are respectively arranged on two support frames. The cable trays 7 are located outside the support frames and are fixedly arranged on two legs 12 of the support frames.

[0033] Due to the long length of the open-air belt conveyor and the complex and changeable terrain, as the detection technology becomes increasingly advanced, the traditional detection method is no longer suitable for existing equipment. Therefore, in this embodiment, inspection robots 8 are respectively arranged on two support frames, and the inspection track 9 of the inspection robot 8 is located on the outside of the support frame and is fixedly arranged on the two legs 12 of the support frame.

[0034] In this embodiment, the corresponding legs 12 of the two support frames are arranged on the same concrete sleeper 10, and the inspection track 9 is fixedly arranged on all concrete sleepers 10. The concrete sleeper 10 is used as the basis of the intermediate frame 1 and the inspection track 9, which greatly reduces the cost compared with the traditional steel structure light rail.

[0035] The belt conveyor body in this embodiment also includes an upper roller assembly 2 and a lower roller assembly 4 arranged up and down, and the two ends of the upper roller assembly 2 are respectively suspended on two hooks 3 of the same group of suspension devices; the two ends of the lower roller assembly 4 are respectively arranged on corresponding quick disassembly and assembly devices.

[0036] The upper roller assembly 2 in this embodiment is a single-hook articulated roller group, including three roller sections. The articulated roller groove angle a of the single-hook articulated roller group is 35°, which is convenient for disassembly and assembly; the lower roller assembly 4 is a chain-type articulated roller group, including two roller sections. The articulated roller groove angle b of the chain-type articulated roller group is 10°, which is convenient for disassembly and assembly.

[0037] The above describes in detail a preferred embodiment of the belt conveyor body of the utility model, and there are more embodiments that will not be described in detail here. In summary, the belt conveyor body of the utility model effectively solves the problem that the upper roller assembly 2 cannot be adjusted and is inconvenient to disassemble and assemble. Its structure is simple and reasonable, and its performance is greatly improved.

[0038] The present utility model is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative labor are all within the protection scope of the present utility model.
