Description

Technical Field

[0001] The utility model belongs to the technical field of conveyors, in particular to a tubular belt conveyor. Background Art

[0002] Tubular belt conveyors can transport bulk materials, including limestone, coal, ore, grain, cement, etc. They can also transport some difficult-to-handle materials such as tailings, bauxite and filter dust, and have a wide range of applications. The conveying process of tubular belt conveyors is closed cross-section transportation. Compared with ordinary belt conveyors, they will not cause greater fluidity between material particle sizes. Under the same conditions, they can transport large quantities and are particularly suitable for long-distance off-road transportation in complex terrain with steep slopes and many turns along the route. They have good economy and adaptability.

[0003] The existing pipe pile belt conveyor maintains the tubular shape of the conveyor belt through multiple rollers, and the rollers maintain conveying contact with the conveyor belt. As the conveyor runs, the contact friction between the rollers and the conveyor belt will cause certain wear on the rollers and the conveyor, especially the rollers at the bends of the conveyor belt, which will be subject to additional lateral pressure from the conveyor belt. The existing pipe pile belt conveyor lacks monitoring of the force and wear of the rollers, which are generally determined by visual inspection by personnel, and cannot provide a scientific and accurate basis for the installation and subsequent maintenance and replacement of the rollers, making it impossible for personnel to perform maintenance in a timely manner. In order to solve the above-mentioned problems, a tubular belt conveyor is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a tubular belt conveyor in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is as follows: a tubular belt conveyor, comprising a belt conveyor pipe and a roller bracket, the roller bracket is provided with a through hole, the belt conveyor pipe passes through the through hole, a fixing frame fixedly installed on the roller bracket is arranged around the through hole, pressure sensors are installed on both sides of the fixing frame, a supporting frame is fixedly installed on the pressure sensor, a roller is rotatably connected to the supporting frame, a lifting frame is fixedly installed on the fixed frame, and a wire laser sensor is fixedly installed on the lifting frame.

[0006] In a preferred embodiment, the fixing frame is an L-shaped structure, and the supporting frame is a U-shaped structure.

[0007] In a preferred embodiment, the lifting frame is a Z-shaped structure.

[0008] In a preferred embodiment, the pressure sensor and the line laser sensor are both externally connected to a server host.

[0009] In a preferred embodiment, the generating end of the line laser sensor is aligned with the surface of the roller.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the utility model, the line laser sensor on the lifting frame can perform laser irradiation detection on the surface of the roller and send the data to the server host. The server host can be used to analyze the surface of the roller, so as to detect the degree of wear of the roller, thereby monitoring the use status of the roller 7 and providing a basis for the maintenance and replacement of the roller.

[0012] 2. In the utility model, when the belt conveyor pipe moves, the automatic rebound pressure of the conveyor belt and the lateral pressure when the belt conveyor pipe turns will give pressure to the roller. At this time, the two pressure sensors can detect the pressure at both ends of the roller, and then the server host will compare the data. When the contact surface between the belt conveyor belt and the roller is offset, the force on the pressure sensor close to the contact surface between the belt conveyor belt and the roller will be greater than the pressure of the other pressure sensor, so as to obtain the pressure deviation direction of the roller, which can help personnel analyze the offset position of the belt conveyor pipe, thereby monitoring the running status of the belt conveyor pipe, and also analyze the force on the roller, so as to provide a basis for the installation and maintenance of the roller in the later stage.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The following will be combined Figure 1-Figure 2 The tubular belt conveyor according to the embodiment of the utility model is described in detail.

[0018] Example:

[0019] The tubular belt conveyor provided by the embodiment of the utility model is referred to Figure 1 to Figure 2 As shown, it includes a belt conveyor pipe 1 and a roller bracket 2. The roller bracket 2 is provided with two through holes 3. The belt conveyor pipe 1 passes through the through holes 3. A fixing frame 4 fixedly installed on the roller bracket 2 is arranged around the through holes 3. The fixing frame 4 is an L-shaped structure. A supporting frame 6 is arranged on the fixing frame 4. The supporting frame 6 is a U-shaped structure. A roller 7 is rotatably connected to the supporting frame 6. This structure uses the fixing frame 4 and the supporting frame 6 to support the roller 7, and uses the roller 7 to support the belt conveyor pipe 1, while maintaining the tubular shape of the belt conveyor pipe 1, thereby ensuring stable transportation of materials.

[0020] refer to Figure 1 to Figure 2 As shown, pressure sensors 5 are installed on both sides between the support frame 6 and the fixed frame 4, and the pressure sensors 5 are externally connected to the server host. In this structure, when the belt conveyor pipe 1 moves and runs, the automatic rebound pressure of the conveyor belt and the lateral pressure when the belt conveyor pipe 1 turns will give a pressure to the roller 7. At this time, the two pressure sensors 5 can detect the pressure at both ends of the roller 7, and then the server host will compare the data. When the contact surface between the belt conveyor belt 1 and the roller 7 is offset, the pressure on the pressure sensor 5 close to the contact surface between the belt conveyor belt 1 and the roller 7 will be greater than the pressure of the other pressure sensor 5, so as to obtain the pressure deviation direction of the roller 7, which can help personnel analyze the offset position of the belt conveyor pipe 1, thereby monitoring the running state of the belt conveyor pipe 1, and also analyze the force on the roller 7, so as to provide a basis for the installation and maintenance of the roller 7 in the later stage.

[0021] It should be noted that the pressure sensor 5 is an existing device, the model of the pressure sensor 5 is LCF300, and the specific equipment and analysis system for the data analysis of the pressure sensor 5 designed above are already public, and will not be introduced in detail here.

[0022] refer to Figure 1 to Figure 2 As shown, a lifting frame 8 is fixedly mounted on the fixed frame 4, and the lifting frame 8 is a Z-shaped structure. A line laser sensor 9 is fixedly mounted on the lifting frame 8, and the generating end of the line laser sensor 9 is aligned with the surface of the roller 7. The line laser sensor 9 is externally connected to the server host. The line laser sensor 9 on the lifting frame 8 of this structure can perform laser irradiation detection on the surface of the roller 7, and send the data to the server host. The server host can be used to analyze the surface of the roller 7, so as to detect the degree of wear of the roller 7, thereby monitoring the use status of the roller 7, and providing a basis for the maintenance and replacement of the roller.

[0023] It should be noted that the line laser sensor 9 is an existing device, the signal of the line laser sensor 9 is ZLDS202, and the specific equipment and detection and analysis systems involved in the above-mentioned laser wear detection are all existing public technologies, which will not be introduced in detail here. There are many existing cases that can also prove the feasibility of laser wear. For example, patents No. CN217059976U, CN113686880B and other patents all involve laser wear detection.

[0024] It should be noted that the monitoring equipment disclosed in the above embodiment is applied to the pipe pile belt conveyor, and belongs to the field of auxiliary equipment for the pipe pile belt conveyor.

[0025] The implementation principle of the tubular belt conveyor of the embodiment of the present application is as follows: when the belt conveyor pipe 1 moves and runs, the conveyor belt will automatically rebound due to the pressure and the lateral pressure when the belt conveyor pipe 1 turns, so that the roller 7 will be subjected to a pressure. At this time, the two pressure sensors 5 can detect the pressure at both ends of the roller 7, and then the server host will compare the data. When the contact surface between the belt conveyor belt 1 and the roller 7 is offset, the pressure sensor 5 close to the contact surface between the belt conveyor belt 1 and the roller 7 will be greater than the pressure of the other pressure sensor 5, so that the pressure deflection direction of the roller 7 can be obtained, which can help personnel analyze the offset position of the belt conveyor pipe 1, thereby monitoring the running state of the belt conveyor pipe 1;

[0026] At the same time, the line laser sensor 9 on the lifting frame 8 can perform laser irradiation detection on the surface of the roller 7 and send the data to the server host. The server host can be used to analyze the surface of the roller 7, so as to detect the degree of wear of the roller 7, thereby monitoring the use status of the roller 7 and providing a basis for roller maintenance and replacement.
