Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to a device for replacing upper and lower rollers of a belt conveyor. Background Art

[0002] As we all know, belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, rollers, drums, tensioning devices, transmission devices, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveyor line. Rollers are important components of belt conveyors. There are many types and large quantities of rollers. They can support the weight of conveyor belts and materials. In daily production, they often suffer from wear and tear, bearing damage, and other problems, and need to be replaced frequently.

[0003] In the conveying system, according to the different positions of the rollers, the rollers can be divided into two types: upper rollers and lower rollers; the upper roller is usually located at the top of the conveyor belt and is a supporting device in the conveyor belt system. It can support the conveyor belt and help balance the weight of the material. Since the upper roller is more susceptible to the impact of the material than the lower roller, it usually adopts a more sturdy structural design to ensure its long-term durability; the lower roller is usually located at the bottom of the conveyor belt. It is one of the main devices that supports the conveyor belt and the material and ensures that they pass smoothly through the conveyor belt system. The lower roller is usually larger than the upper roller and requires a stronger load-bearing capacity. They usually use straight pipes and springs and rubber sleeves with shock-absorbing functions to ensure their correct operation. The upper roller and the lower roller are installed in different positions. The upper roller is directly installed on the surface of the conveyor belt, while the lower roller is installed under the conveyor belt.

[0004] At present, traditional roller replacement operations usually require manual lifting and supporting of the belt, while also removing the old rollers and installing new ones. This is a large amount of work and is difficult; it usually requires the collaboration of multiple people. Replacing the upper roller generally requires the cooperation of 2 people, while replacing the heavier lower roller requires 3-4 people or even more. Sometimes the operator also needs to lean over to enter the narrow space between the upper belt and the lower belt to work, which not only brings certain safety hazards to the roller replacement operation, but also seriously affects the work efficiency.

[0005] The prior art discloses a belt conveyor roller replacement device, CN213325149U, which comprises a lower support seat, wherein the first side plate and the second side plate are respectively installed on both sides of the surface of the lower support seat, and an L-shaped rotating bracket is arranged between the first side plate and the second side plate; a third mounting hole is provided at the top of one arm of the L-shaped rotating bracket, a U-shaped upper support seat is arranged on the upper part of the L-shaped rotating bracket, and fourth mounting holes are provided on the surfaces of the two side plates of the U-shaped upper support seat, and a second column pin is installed in the third mounting hole of the L-shaped rotating bracket and the fourth mounting hole of the U-shaped upper support seat, and a pressure rod is installed in the other arm sleeve of the L-shaped rotating bracket. The prior art has a simple structure, is safe and reliable, and is easy to operate, and a single person can complete the roller replacement operation.

[0006] However, the above prior art is only applicable to the replacement of the upper roller and cannot solve the problem of the replacement of the lower roller.
