Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, and specifically relates to a tear-resistant protective device for belt conveyors. Background Technology

[0002] The main causes of belt conveyor tearing include the following: Belt misalignment: During the transportation of materials, the belt may run off-center due to impact or uneven accumulation of ore in some areas. If the belt is in a misaligned state for a long time, it may tear when scratched by hard or sharp objects.

[0003] Belt shaft problem: In a steel cord belt, when the machine starts or stops suddenly, the steel wire rope will be subjected to instantaneous impact. Under long-term repeated action, the broken end of the steel wire rope may penetrate the belt and be exposed outside the belt cover rubber, resulting in tearing.

[0004] Ore accumulation and blockage: When the ore transport volume is too large, the ore overflows from the chute, blocking the gap between the idler roller and the belt, and the strong pressure on the belt causes tearing.

[0005] Scratches: Sharp objects get stuck at the bottom of the chute or fall from a height and pierce the belt, causing scratches or punctures.

[0006] Aging: Belts will show signs of aging after prolonged use, especially in high-temperature and corrosive environments, where the aging process is accelerated and tearing is more likely.

[0007] Material impact: When materials are poured directly from a height, the large drop between materials results in a strong impact force, which may cause the conveyor belt to tear.

[0008] Besides these, there are other reasons that can cause belts to tear. The main problem is that belts are easily worn during transmission. After wear, the belt will stop running, and over time, this will increase the risk of tearing. How to protect the belts of belt conveyors is an important problem that needs to be solved. There is an urgent need to design a belt conveyor anti-tear protection device to solve the tearing problem of belt conveyors. Utility Model Content

[0009] The purpose of this invention is to provide a tear-resistant protective device for belt conveyors, which solves the technical problem of belt conveyors being prone to tearing.

[0010] This utility model is achieved using the following technical solution: A belt conveyor tear-resistant protective device includes a humidification component, a stamping component, a main frame part, a collection part, and a positioning part. The main frame part is located at the center of the protective device, and the humidification component, the stamping component, the collection part, and the positioning part are respectively mounted on the main frame part. The main frame includes a frame, with columns fixedly installed at the bottom of the frame. A clamping plate is fixedly mounted on the column, and a clamping plate is welded to the right side of the clamping plate. A hydraulic cylinder is fixedly installed on the lower side wall of the clamping plate, and a top plate is fixedly mounted on the piston rod of the hydraulic cylinder. The humidification component includes a mounting bracket, which is fixedly installed inside the frame on the right side. A water pump is fixedly installed on the right side of the mounting bracket, and a spray pipe is installed at the outlet end of the water pump. A water tank is fixedly installed on the right side of the top surface of the frame, and a first connecting pipe connects the water tank and the water pump. There are two sets of stamping components arranged symmetrically on top and bottom. The stamping components include a motor and a carriage. The carriage runs through the top and bottom surfaces of the frame. A guide ring is installed between the carriage and the frame. A chain is welded to the side of the carriage. The motor is fixedly installed on the frame. A sprocket is fixedly fitted on the motor shaft of the motor. The sprocket meshes with the chain. A pressure plate is fixedly installed at the end of the carriage. The collection section includes a material pump, which is fixedly mounted on the frame. A feed pipe is fixedly installed at the feed end of the material pump, and collection pipes are evenly installed at the end of the feed pipe. A second connecting pipe connects the material pump to the pressure plate located on the lower side. The positioning part includes a connecting plate and a cover ring. The connecting plate is fixedly installed on the frame. A connecting frame is fixedly installed between the cover ring and the frame. Push plates are evenly installed on the inner side of the cover ring. An air bladder is installed between the push plates and the cover ring. An air pump is fixedly installed on the surface of the connecting plate. A third connecting pipe is connected between the air pump and the cover ring.

[0011] The clamping plate and top plate are used to position and clamp the device.

[0012] The pressure plate presses the coal material to compact it onto the surface of the conveyor belt, forming a protective layer that enhances the belt's tear resistance.

[0013] More preferably, the frame is a U-shaped plate, with a mounting bracket installed on the open side of the U-shaped plate, the upper side plate of the U-shaped plate being the top surface of the frame, and the lower side plate being the bottom surface of the frame.

[0014] More preferably, the upper and lower side plates of the frame are respectively provided with holes for the slide to slide.

[0015] In a further preferred embodiment, the feed pipe is connected to the collection pipe, and the surface of the collection pipe is uniformly provided with holes.

[0016] More preferably, the cover ring is a hollow structure, the cover ring is connected to the third connecting pipe, the cover ring is connected to the airbag, the push plate is an arc-shaped structure, the cover ring is a hollow ring, the airbag is a rubber airbag, and a flexible tube is provided between the airbag and the cover ring so that they can communicate, or an interconnecting hole is provided between the airbag and the cover ring.

[0017] More preferably, the pressure plate has a U-shaped structure, with the lower pressure plate being hollow and having uniformly distributed mesh holes on its surface. The pressure plate is connected to the second connecting pipe. The pressure plate is divided into upper and lower parts: the upper pressure plate is solid, and the lower pressure plate is hollow. The upper pressure plate mainly provides the pressing force, while the hollow lower pressure plate provides pressure and also allows material to pass through. The material passed through is the sucked-up coal, which covers the back of the conveyor belt, covering both the surface and the back of the belt with a coal layer to increase tear resistance.

[0018] More preferably, the feed tube is made of carbon steel.

[0019] This invention combines various components to cover both the surface and back of the belt conveyor with a protective layer, thus providing tear-resistant protection for the belt.

[0020] This invention, through its collection section, collects coal dust during belt conveyor operation. The collected coal dust, combined with humidification by a humidifying component and compression by a lower pressing component, coats and humidifies the back of the belt, forming a protective layer. This layer is then compacted on the back of the belt. As the belt travels, the humidified coal dust gradually dries and falls off. The compression by the upper pressing component further compacts the coal dust on the belt surface, preventing loose coal lumps from causing wear and tear, thus providing tear protection. The protective layer is formed on both the surface and back of the belt, utilizing the compression of the coal itself. The positioning section allows for adjustment of the coal dust thickness on the belt by changing the size of the ring formed by the push plates. The clamping plates and top plate facilitate easy installation and positioning of the device. This invention, through the combination of its components, covers both the surface and back of the belt conveyor with a protective layer, providing tear protection. Attached Figure Description

[0030] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0031] A belt conveyor tear-resistant protective device includes a humidification component A, a stamping component B, a main frame 6 parts C, a collection part D, and a positioning part E. The main frame 6 parts C is located at the center of the protective device, and the humidification component A, the stamping component B, the collection part D, and the positioning part E are respectively mounted on the main frame 6 parts C.

A water pump 2 is fixedly installed on the right side of the mounting bracket 28. A spray pipe 1 is installed at the liquid outlet end of the water pump 2. A water tank 5 is fixedly installed on the right side of the top surface of the frame 6. A first connecting pipe 4 connects the water tank 5 and the water pump 2. The stamping assembly B has two sets and is arranged symmetrically above and below. The stamping assembly B includes a motor 11 and a slide 8. The slide 8 passes through the top and bottom surfaces of the frame 6 respectively. A guide ring 7 is installed between the slide 8 and the frame 6. A chain 9 is welded to the side of the slide 8. The motor 11 is fixedly installed on the frame 6. A sprocket 10 is fixedly mounted on the motor shaft of the motor 11. The sprocket 10 meshes with the chain 9. A pressure plate 12 is fixedly installed at the end of the slide 8. The collection section D includes a material pump 19, which is fixedly installed on the frame 6. A feed pipe 18 is fixedly installed at the feed end of the material pump 19. Collection pipes 3 are evenly installed at the end of the feed pipe 18.

The connecting plate 17 is fixedly installed on the frame 6. A connecting bracket 13 is fixedly installed between the cover ring 14 and the frame 6. Push plates 16 are evenly installed on the inner side of the cover ring 14. An airbag 15 is installed between the push plate 16 and the cover ring 14. An air pump 21 is fixedly installed on the surface of the connecting plate 17. A third connecting pipe 22 connects the air pump 21 and the cover ring 14.

[0032] Frame 6 is a U-shaped plate. Mounting bracket 28 is installed on the open side of the U-shaped plate. The upper side plate of the U-shaped plate is the top surface of frame 6, and the lower side plate is the bottom surface of frame 6.

[0038] The working principle is as follows: First, the device is installed and positioned. The hydraulic cylinder 27 is controlled, and the device is positioned and installed using the clamping of the top plate 26 and clamping plate 25. The pressure plate 12 and the cover ring 14 are placed over the upper and lower sides of the belt conveyor. Water is added to the water tank 5. The air pump 21 is controlled to inflate the air bag 15. By controlling the inflation amount of the air bag 15, the size of the ring formed by the push plate 16 can be controlled, which facilitates the control of the thickness of the coal conveyed on the belt conveyor. During the coal conveying process, the material pump 19 collects the coal powder through suction and discharges it to the back of the belt through the lower pressure plate 12. Simultaneously, the water pump 2 sprays water to humidify and increase the adhesion of the coal. By controlling the motor 11, the motor can rotate forward and backward, causing the upper and lower pressure plates 12 to press the surface and back of the belt respectively, forming a protective layer on the belt surface. This provides tear protection for the belt conveyor during coal conveying.
