Description

Belt conveyor with detachable H-frame Technical Field

[0001] This utility model belongs to the field of mining equipment technology, and more specifically, it relates to a detachable H-frame for a belt conveyor. Background Technology

[0002] Traditional coal mine belt conveyor supports are generally made of two columns and a crossbeam welded together in an integrated H-shaped structure, commonly known as an H-frame. This structure has certain advantages in practical use. Due to its integral molding, it has high structural strength and stability, and can effectively bear the weight of the conveyor belt and the conveyed materials, adapting to the complex and ever-changing geological conditions underground.

[0003] However, this traditional H-frame has significant drawbacks. Its non-disassembly nature causes considerable inconvenience during transportation. Due to its irregular shape, it occupies a lot of space when transported by tanker truck; typically, a tanker truck can only carry five H-frames, severely limiting the amount transported per trip, leading to low transportation efficiency and increased transportation and time costs. Furthermore, if any component of a traditional H-frame is damaged, especially a critical leg, its non-disassembly often necessitates scrapping the entire H-frame, resulting in significant resource waste and economic losses.

[0004] To address this issue, existing technology provides a detachable H-type support for belt conveyors, mainly comprising a left support leg, a circular tube, fixing bolts, a detachable fastening device, and a right support leg. The detachable fastening device is fixed to the left and right support legs respectively by the fixing bolts, ensuring three-line contact between the annular body and the left and right fixing claws with the cross-section of the circular tube, and securing it by the clamping action of the left and right fixing claws. This detachable design of the columns and beams facilitates the disassembly and transportation of the H-frame. However, the structure of this detachable fastening device is relatively complex. Long-term mechanical wear can easily lead to loosening of the fit between components, resulting in easy damage and loss, affecting installation and use.

[0005] Existing technology also provides an assemblable H-frame structure for belt conveyors, including a left channel steel and a right channel steel. A left slot with openings at the top, bottom, and left ends is fixed to the lower right side of the left channel steel, and a right slot is fixed to the lower left side of the right channel steel. The left and right slots are symmetrical. A horizontal seamless steel pipe is installed between the left and right channel steels. An inverted U-shaped left clamp with openings at the front, rear, and bottom ends is fixed to the left end of the seamless steel pipe. The shape and size of the left clamp match the left slot, and the left clamp is inserted into the left slot. A right clamp is fixed to the right end of the seamless steel pipe. The left and right clamps are symmetrical, and the shape and size of the right clamp match the right slot, and the right clamp is inserted into the right slot. However, this direct insertion method makes it difficult to achieve effective fastening between the uprights and the crossbeams, and the inverted U-shaped clamp is prone to deformation, causing the H-frame to sway when supporting the belt conveyor, posing a safety hazard.

[0006] Therefore, although the existing H-frames can solve the problem of H-frames being inconvenient to transport by disassembling and assembling them, the performance of these H-frames in actual use is relatively poor and they are difficult to meet the requirements. Summary of the Invention

[0007] The purpose of this utility model is to provide a detachable H-frame for a belt conveyor, so as to solve the technical problem that the existing detachable H-frames have poor performance and are difficult to meet the requirements.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a detachable H-frame for a belt conveyor is provided, comprising two uprights and a crossbeam. Each of the two uprights has a slot in the middle. Both ends of the crossbeam are provided with claws for engaging with the slots and abutment plates for abutting against the corresponding uprights. The claws extend downward and are vertically arranged, with the slots surrounding the lower end of the claws. The side of the slot opposite to the upright and the side of the claw opposite to the upright are both inclined surfaces.

[0009] The beneficial effects of the detachable H-frame belt conveyor provided by this utility model are as follows: Compared with the prior art, when needed, this utility model allows for easy installation and removal of the following: after the uprights are erected, the crossbeam is placed horizontally in the middle of the uprights, and the claws are pressed into the slots. During the pressing process, the inclined surfaces of the claws and slots cooperate to form a wedge-shaped clamping structure, causing the abutment plate to press against the crossbeam to form a self-locking mechanism, resulting in a relatively robust connection that meets usage requirements. After use, the crossbeam can be removed. This method has a simple structure, and installation and disassembly are relatively simple and convenient. Furthermore, there are no extra parts, preventing installation difficulties due to the loss of small components. Simultaneously, the connection is firm after installation, preventing shaking and deformation, and greatly reducing safety hazards. Attached Figure Description

[0024] The detachable H-frame of the belt conveyor provided by this utility model will now be described.

[0025] As shown in Figures 1 and 2, the first embodiment of this utility model provides a detachable H-frame for a belt conveyor, including two uprights 10 and a crossbeam 20. Each of the two uprights 10 has a slot 11 in the middle. Both ends of the crossbeam 20 are provided with claws 21 for cooperating with the slots 11 and abutment plates 22 for abutting against the corresponding uprights 10. The claws 21 extend downward and are vertically arranged, and the slots 11 surround the lower end of the claws 21. The side of the slots 11 opposite to the uprights 10 and the side of the claws 21 opposite to the uprights 10 are both inclined surfaces.

[0026] When needed, after erecting the column 10, place the crossbeam 20 horizontally in the middle of the column 10, and press the claws 21 into the slots 11. During the pressing process, the claws 21 and the inclined surfaces of the slots 11 cooperate to form a wedge-shaped clamping structure, so that the abutment plate 22 abuts against the crossbeam 20 to form a self-locking mechanism, creating a relatively strong connection that meets the usage requirements. After use, the crossbeam 20 can be removed. This method has a simple structure, and installation and disassembly are relatively simple and convenient. Moreover, there are no extra parts, so there is no situation where installation is difficult due to the loss of small parts. At the same time, the connection is firm after installation, and it is not easy to shake or deform, which can greatly reduce safety hazards.

[0027] As shown in Figure 3, this utility model provides another specific embodiment based on the first embodiment as follows:

[0028] The abutment plate 22 is provided with a limiting lock groove 23 on the side facing the column 10, and the column 10 is provided with a limiting protrusion 12 that cooperates with the limiting lock groove 23.

[0029] After the claw 21 is pressed into the slot 11 and positioned, the limiting protrusion 12 is engaged in the limiting lock slot 23 to form a lock, which further enhances the connection strength between the column 10 and the beam 20 and prevents the claw 21 from coming out due to accidental collisions or other reasons, thus affecting safety.

[0030] As shown in Figure 4, this utility model provides another specific embodiment based on the first embodiment as follows:

[0031] The column 10 is provided with a through hole, a locking pin 13, and an elastic element 14. The through hole is horizontally arranged on the column 10, with one end facing the abutment plate 22 and the other end facing away from the abutment plate 22. The locking pin 13 slides through the through hole. The elastic element 14 is connected to both the locking pin 13 and the column 10 to provide elastic force to the locking pin 13, so that the end of the locking pin 13 located in the through hole facing the abutment plate 22 protrudes from the surface of the column 10 in its natural state, forming a limiting protrusion 12. Specifically, the elastic element 14 can be a spring, a sheet, or an elastic block, etc., that provides elasticity.

[0032] During installation, under the action of the elastic element 14, when the claw 21 is pressed into the slot 11, the limiting protrusion 12 at the end of the locking pin 13 retracts into the through hole. After the claw 21 and the slot 11 are in place, the limiting protrusion 12 springs back and locks into the limiting locking groove 23. When disassembly is required, pulling the other end of the locking pin 13 causes the limiting protrusion 12 to retract into the through hole, making it easy to remove the crossbeam 20. With this structure, the dimensions of the limiting protrusion 12 and the limiting locking groove 23 can be designed to be relatively large, resulting in better locking and engagement, and reducing wear on the limiting protrusion 12, thus extending its service life.

[0033] When the column 10 is a square tube, the abutment plate 22 is a flat plate that fits against the surface of the column 10. When the column 10 is a round tube, the abutment plate 22 is an arc-shaped plate that fits against the surface of the column 10. This improves the fit between the abutment plate 22 and the column 10, thereby increasing the structural strength.

[0034] The claw 21 and the abutment plate 22 can be an integral structure for ease of manufacturing.

[0035] The column 10 is also provided with a back plate 15, which is attached to and fixed on the column 10. The back plate 15 is connected to the slot 11, and the abutment plate 22 abuts against the back plate 15.

[0036] By setting the back plate 15, the connection strength between the slot 11 and the column 10 can be improved and the manufacturing convenience can be enhanced. On the other hand, the strength of the column 10 can also be improved, thereby improving the overall structural strength and safety.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
