Description

Technical Field

[0001] The utility model relates to the technical field of limit protection equipment, in particular to an anti-scratch limit protection device for a belt conveyor. Background Technique

[0002] A belt conveyor is an important transportation equipment in ore transportation. It is a continuous transportation equipment that uses a conveyor belt as a traction and load-bearing member and transports materials through the movement of the conveyor belt carrying the materials. The conveyor belt winds around the driving roller and the tail roller to form an endless ring belt. The upper and lower conveyor belts are supported by rollers to limit the deflection of the conveyor belt. The tensioning device provides the required tension for the normal operation of the conveyor belt. When working, the driving device drives the driving roller, and the conveyor belt is driven to run through the friction between the driving roller and the conveyor belt. The materials are loaded on the conveyor belt and move together with the belt. It is widely used in metallurgy, mining, ports, grain, and chemical industries.

[0003] The conveyor belt, also called a belt, is an important component of a belt conveyor and is also one of the more expensive components. Once the belt is damaged in various forms, it will affect the smooth output of ore. Among them, longitudinal scratches on the belt are the most common, frequent, and difficult to repair. Especially after oversized ore or flaky rocks accumulate at the chute opening funnel position, the local deformation of the belt occurs, and the sharp ore is squeezed between the non-working surface of the belt and the flat idler on the idler frame to scratch the belt, causing losses. Subsequently, operators need to carry out repairs, delaying the equipment operation cycle and bringing losses to the enterprise. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-scratch limit protection device for a belt conveyor with reasonable structural design, ingenious concept, low processing and manufacturing cost, less investment, and convenient operation, which can prevent the belt from being scratched, reduce the inspection frequency, and improve the service life of the belt.

[0005] An anti-scratch limit protection device for a belt conveyor of the utility model includes a fixed frame. The number of fixed frames is two. A deformation belt is fixedly installed on the surface between the two fixed frames. A push rod is fixedly connected to the bottom surface of the deformation belt. A connecting cross bar is fixedly installed between the two fixed frames, and a travel switch is fixedly installed on the side wall surface of the connecting cross bar.

[0006] Two set fixed frames can be installed at the hopper position of the chute of the belt conveyor. The installation is convenient and the fixation is stable. The set deformation belt is just located at the bottom surface of the belt. When the belt is running normally, it will not touch the deformation belt. When oversized ores or flaky rocks accumulate at the hopper of the chute, the deformation of the belt will touch the deformation belt. The deformation belt bears the downward pressure and will move downward through the push rod fixedly connected to the bottom surface of the deformation belt at this time, touching the travel switch. The travel switch is interlocked with the PLC control system of the belt conveyor. The PLC control system of the belt conveyor controls the belt conveyor to stop running. Therefore, it can prevent the belt from being scratched during continued operation. After the operator processes the accumulated oversized ores or flaky rocks, the belt conveyor can be normally started to continue running. It can effectively prevent sharp ores from being squeezed between the non-working surface of the belt and the flat idler on the idler frame to scratch the belt, causing losses, which requires the operator to specifically perform repairs and delays the operation cycle of the belt conveyor. The operation is convenient, the use is safe and reliable, and the belt can be protected during long-term use, extending the service life of the belt.

[0007] The described deformation belt is of an arc structure. Connecting plates are fixedly connected to both ends of the deformation belt. Installation holes are arranged on the surface of the connecting plates. The deformation belt can be fixedly installed on the surfaces of the two fixed frames through the fixing rods in the installation holes.

[0008] Setting the deformation belt as an arc structure can keep it consistent with the running surface of the belt. When the belt is accumulated with oversized ores or flaky rocks, it can better receive the deformation of the belt, and then better move downward through the push rod to touch the travel switch, ensuring the limit requirements of the entire protection device and better playing the role of limiting and protecting the belt.

[0009] A protective plate is fixedly connected to the side wall of the described fixed frame.

[0010] The set protective plate can play a limiting role when the deformation belt undergoes deformation displacement, preventing the deformation belt from moving towards the two fixed frames and thus not being able to better touch the travel switch set on the bottom surface, which can further ensure the safe and efficient operation of the entire protection device.

[0011] The described protective plates are respectively arranged at the relative positions between the two fixed frames.

[0012] The cross-section of the described connecting crossbar is set in an L shape.

[0013] Setting the cross-section of the connecting crossbar in an L shape can use angle steel for connection and fixation, saving materials and reducing input costs. At the same time, it can improve the anti-deformation strength of the connecting crossbar, further improve the anti-deformation strength of the entire protection device, and extend the service life of the entire protection device.

[0014] The beneficial effects of the present utility model:

[0015] 1) The two fixed frames set can be installed at the funnel position of the chute opening of the belt conveyor. The installation is convenient and the fixation is stable. The deformation belt set is just located at the bottom surface of the belt. When the belt is running normally, it will not touch the deformation belt. When oversize ores or flaky rocks accumulate at the chute opening funnel, the deformation of the belt will touch the deformation belt. The deformation belt bears the downward pressure and will move downward through the push rod fixedly connected to the bottom surface of the deformation belt at this time, touching the travel switch. The travel switch is interlocked with the PLC control system of the belt conveyor. The PLC control system of the belt conveyor controls the belt conveyor to stop running. Therefore, it can prevent the belt from being scratched during continuous operation. After the operator processes the accumulated oversize ores or flaky rocks, the belt conveyor can be normally started to continue running. It can effectively prevent sharp ores from being squeezed between the non-working surface of the belt and the flat idler on the idler frame to scratch the belt, causing losses, which requires the operator to carry out special maintenance and delays the operation cycle of the belt conveyor. The operation is convenient, the use is safe and reliable, and the belt can be protected in the long term, extending the service life of the belt.

[0016] 2) The deformation belt is set as an arc structure, which can be consistent with the running surface of the belt. When the belt is accumulated with oversize ores or flaky rocks, it can better receive the deformation of the belt, and then better move downward through the push rod to touch the travel switch, ensuring the limit requirements of the entire protection device and better playing the role of limiting and protecting the belt.

[0017] 3) The protective plate set can play a limiting role when the deformation belt undergoes deformation displacement, preventing the deformation belt from moving towards the two fixed frames, and then being unable to better touch the travel switch set at the bottom surface, which can further ensure the safe and efficient operation of the entire protection device.

[0018] 4) The cross-section of the connecting cross bar is set as an L shape, and angle steel can be used for connection and fixation, saving materials and reducing the input cost. At the same time, it can improve the anti-deformation strength of the connecting cross bar, further improve the anti-deformation strength of the entire protection device, and extend the service life of the entire protection device.

[0019] 5) The structure is reasonably designed, ingeniously conceived, with low processing and manufacturing costs, less investment, and convenient operation. It can prevent the belt from being scratched, reduce the maintenance frequency, and improve the service life of the belt. It has been put into production and use, and the use effect is good, which can effectively protect the belt. Therefore, it is worthy of popularization and application on a large scale.
