Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt laying technology, specifically relating to a laying device for a large-angle conveyor belt. Background Technology

[0002] Inclined-angle belt conveyors are mainly used for continuous conveying of bulk materials at steep angles. They typically employ conveyor belts with corrugated sidewalls and cross diaphragms, with an inclination angle generally greater than 18°. They are widely used in industries such as coal, grain, building materials, chemicals, hydropower, agriculture, ports, and metallurgy. They offer advantages such as high conveying reliability, energy saving, and reliable and economical material handling.

[0003] A steep-angle belt conveyor generally consists of an unloading section, a transmission section, a motor, a brake, a backstop, a tensioning device, a frame, a deep-groove idler assembly, and a tail assembly. The frame includes idler sets and longitudinal beams. When laying a steep-angle belt conveyor on site, the longitudinal beams of the frame are typically erected first, followed by the laying of the belt, and then the connection of the idler sets and motor.

[0004] A circular conveyor belt is a fixed-length, precisely calculated ring structure. Circular conveyor belts offer advantages such as balanced transport and minimal stretching. Laying circular conveyor belts is relatively complex, especially for long-distance, steeply inclined belts, where the requirements are even higher.

[0005] The problem with existing technology is that conventional steep-angle circular conveyor belts are laid using steel pipes or wire ropes pulled by winches. This method not only damages the conveyor belt but also results in uneven stress, making it inconvenient for the installation of belt conveyors. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the prior art by providing a laying device for conveyor belts with large inclination angles, which has the advantages of convenient operation, minimal belt damage, and simple structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a laying device for a large-angle conveyor belt, comprising two oppositely arranged mounting members, each mounting member having a lifting hole at its top, a rotating drum connecting shaft between the two mounting members, a belt positioning member rotatably mounted on the outer ring of the rotating drum connecting shaft, an outer mounting shaft on the outer surface of each mounting member, a positioning roller rotatably mounted on the outer mounting shaft for cooperating with the longitudinal beam of the conveyor belt, and a limit flange on the inner end of the positioning roller.

[0008] In the above scheme, lifting holes are opened on the top of the two mounting components for connecting lifting equipment. The mounting components are connected by a rotating drum connecting shaft. The outer ring of the rotating drum connecting shaft is equipped with a belt positioning component to cooperate with the inner side of the conveyor belt, thereby positioning the conveyor belt and laying it along the conveying direction, facilitating belt movement and avoiding damage. An outer mounting shaft is set on the outer side of the mounting component to connect a positioning roller. The positioning roller is used to cooperate with the longitudinal beam of the conveyor belt to guide and position the laying device during the laying process, avoiding collisions between the laying device, the conveyor belt and the machine body and the bottom space of the conveyor belt during the operation of the lifting equipment, thus improving the laying efficiency. The limiting flange on the inner side of the positioning roller is used to cooperate with the longitudinal beam to limit the horizontal movement range of the laying device and prevent it from falling off the longitudinal beam.

[0009] Furthermore, the mounting component is provided with at least two external mounting shafts, each of which is equipped with a positioning roller, and the positioning rollers on both sides of the mounting component are symmetrically arranged.

[0010] By setting up two or more external mounting shafts, and cooperating with the positioning rollers on the external mounting shafts, the stability of the laying device when moving along the longitudinal beam of the conveyor belt can be improved.

[0011] Furthermore, a conveyor belt limiting beam is detachably provided between the two mounting components, and the conveyor belt limiting beam is arranged parallel to the rotating drum connecting shaft.

[0012] By setting a conveyor belt limiting beam parallel to the rotating drum connecting shaft, the position of the outer side of the conveyor belt is restricted, thereby improving the positioning effect.

[0013] Furthermore, the mounting component has mounting holes, and both ends of the conveyor belt limiting beam are connected to the mounting holes by fasteners.

[0014] By opening mounting holes on the mounting parts and using fasteners to connect with both ends of the conveyor belt limiting beam, the positioning of the conveyor belt limiting beam can be achieved.

[0015] Furthermore, the mounting component is provided with a U-shaped adjustment groove, and a limiting clamping roller is rotatably arranged between the two mounting components. The two ends of the limiting clamping roller are detachably connected to the U-shaped adjustment groove by fastener two.

[0016] Limiting rollers are installed to limit the outer side of the conveyor belt. The limiting rollers can rotate to reduce the frictional resistance between them and the conveyor belt. U-shaped adjustment grooves are provided to facilitate the installation, disassembly, and position adjustment of the limiting rollers. It can be used for the installation of conveyor belts of various thicknesses and sizes.

[0017] Furthermore, the two ends of the limiting roller are provided with screws, and the screws are threadedly connected to fasteners.

[0018] The connection and fixation are convenient because the screw is used to connect with the fastener.

[0019] Furthermore, the limiting clamping roller includes a roller shaft, on which a roller body is rotatably mounted, and at both ends of the roller shaft are screws. The overall structure is simple.

[0020] The mounting component is a metal plate structure, and the belt positioning component includes a roller.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By setting up installation components to connect with hoisting equipment, and setting up rotating drum connecting shafts and belt positioning components to position the inner side of the conveyor belt, the contact area with the conveyor belt is increased, so that the belt is evenly stressed and the positioning is stable; setting up belt positioning components reduces the friction on the inner side of the belt, reduces belt damage, facilitates belt laying, and simplifies operation.

[0023] 2. By setting an external mounting shaft and positioning rollers, the laying device can be easily positioned in conjunction with the longitudinal beam of the conveyor belt, thereby avoiding collisions between the laying device, the conveyor belt and the machine body and the space under the conveyor belt during the laying process, preventing belt damage, improving laying efficiency, and simplifying operation;

[0024] 3. Detachable limiting rollers or conveyor belt limiting beams are installed to improve the positioning effect of the conveyor belt, enhance laying stability, and the device has a simple structure. Attached Figure Description

[0031] In the above scheme, lifting holes 2 are opened on the top of the two mounting parts 1 for connecting the lifting equipment. The mounting parts 1 are connected by a rotating drum connecting shaft 3. The outer ring of the rotating drum connecting shaft 3 is equipped with a belt positioning part 4 for cooperating with the inner side of the conveyor belt to realize the positioning of the conveyor belt and the laying along the conveying direction, which facilitates the movement of the belt and avoids damage. An outer mounting shaft 5 is set on the outer side of the mounting part 1 to connect the positioning roller 6. The positioning roller 6 is used to cooperate with the longitudinal beam 17 of the conveyor belt to realize the guiding positioning of the laying device during the laying process, and to avoid collision between the laying device, the conveyor belt and the machine body and the bottom space of the conveyor belt during the operation of the lifting equipment, thereby improving the laying efficiency. The limiting flange 7 on the inner side of the positioning roller 6 is used to cooperate with the longitudinal beam to limit the horizontal movement range of the laying device and prevent it from falling off the longitudinal beam.

[0032] The belt positioning component 4 can be a roller structure or a structure with an added sleeve on the outside of the steel pipe. The belt positioning component 4 can rotate with the belt itself under stress balance, which is convenient for laying.

[0038] Furthermore, the mounting component 1 is provided with mounting holes 9, and the two ends of the conveyor belt limiting beam 8 are connected to the mounting holes 9 by fasteners 10.

[0039] By opening mounting holes 9 on the mounting component 1 and using fasteners 10 to connect with both ends of the conveyor belt limiting beam 8, the positioning of the conveyor belt limiting beam 8 can be achieved.

[0040] The conveyor belt limiting beam 8 has a circular cross-section to reduce friction with the conveyor belt. Fastener 10 includes a nut.
