Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a roller structure for real-time detection of belt conveyor operation. Background Art

[0002] Belt conveyor is a common material conveying equipment used to transport various materials in factories, mines, ports, warehouses and other places. The belt conveyor drives the conveyor belt to circulate continuously through the drive device, thereby transporting materials from one location to another.

[0003] The operating status of existing belt conveyors is usually detected by using belt load detection devices such as motor protectors and overload protectors. In actual use, when faults such as coupling disconnection, belt breakage, or drive roller input shaft breakage occur, the motor cannot immediately issue a stop command, resulting in accumulation and leakage of conveyed materials. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a real-time detection roller structure for the operation of a belt conveyor, which solves the technical problem that the operation status detection of the existing belt conveyor usually adopts belt load detection devices such as motor protectors and overload protectors. During actual use, when the belt conveyor coupling is disconnected, the belt is broken, or the input shaft of the transmission roller is broken, the motor cannot immediately issue a stop command, resulting in accumulation, leakage and other faults of the conveyed material.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A roller structure for real-time detection of belt conveyor operation includes a roller, a roller drive shaft, a roller bearing seat, a connecting hole, and a sensor. The roller bearing seat is fixedly connected to a belt bracket, the roller drive shaft is rotatably connected to the inside of the roller bearing seat, the roller is sleeved on the outer surface of the roller drive shaft, the roller contacts the belt surface, the roller rotates under the action of the belt friction force, and the rotation of the roller drives the roller drive shaft to rotate synchronously. The connecting hole is opened inside the roller drive shaft, the sensor is sleeved inside the connecting hole, and the sensing components inside the sensor rotate synchronously with the roller drive shaft.

[0007] Preferably, the roller bearing seat is fixedly connected to the belt support via bolts.

[0008] Preferably, the roller rotates with the belt conveyor under the friction of the belt.

[0009] Preferably, the drum transmission shaft and the drum rotate synchronously.

[0010] Preferably, the sensor is connected to the drum drive shaft through a connecting hole.

[0011] Preferably, the sensor and the drum rotate synchronously.

[0012] The utility model has the following beneficial effects:

[0013] 1. During operation, the belt of the belt conveyor runs, and the roller rotates under the action of the friction force of the belt. The roller drive shaft rotates synchronously with the roller, and the sensor rotates synchronously with the roller through the connecting hole. When the belt conveyor is operating normally, the real-time detection roller is always in a rotating state. When a belt emergency stop failure occurs, such as the transmission device coupling is disconnected, the belt is broken, or the transmission roller shaft is broken, the detection roller stops rotating. At this time, the sensor will issue a motor stop command to stop the motor urgently, and the subsequent processes will stop urgently. The sensor sends a fault signal to cut off the power to the belt conveyor motor and stop it, which can effectively avoid conveyor blockage, leakage, conveyor crushing and other failures caused by belt conveyor coupling disconnection, belt breakage or transmission roller shaft breakage.

[0017] The embodiments of the present application provide a real-time detection roller structure for belt conveyor operation, effectively solving the problem of existing belt conveyor operation status detection generally using belt load detection devices such as motor protectors and overload protectors. In actual use, when a fault such as a belt conveyor coupling disconnection, belt breakage, or drive roller input shaft breakage occurs, the motor cannot immediately issue a stop command, resulting in accumulation and leakage of conveyed materials. During operation, the belt conveyor belt runs, and the roller rotates under the action of the belt friction. The roller drive shaft rotates synchronously with the roller, and the sensor rotates synchronously with the roller through the connection hole. When the belt conveyor operates normally, the real-time detection roller is always in a rotating state. When a belt emergency stop fault occurs, such as a transmission coupling disconnection, belt breakage, or drive roller shaft breakage, the detection roller stops rotating. At this time, the sensor will issue a motor stop command, causing the motor to stop urgently, and subsequent processes to stop urgently. The sensor sends a fault signal to power off the belt conveyor motor and stop it, which can effectively avoid conveyor blockage, leakage, and conveyor crushing caused by belt conveyor coupling disconnection, belt breakage, or drive roller shaft breakage.

[0018] like Figure 1As shown, the technical solution in the embodiment of the present application effectively solves the problem that the existing belt conveyor operation status detection usually adopts motor protectors, overload protectors and other belt load detection devices. In actual use, when the belt conveyor coupling is disconnected, the belt is broken, or the transmission roller input shaft is broken, the motor cannot immediately issue a stop command, resulting in accumulation, leakage and other faults of the conveyed materials. The overall idea is as follows: A belt conveyor operation real-time detection roller structure includes a roller 1, a roller drive shaft 2, a roller bearing seat 3, a connecting hole 4, and a sensor 5. The roller bearing seat 3 is fixedly connected to the belt bracket, the roller drive shaft 2 is rotatably connected to the inside of the roller bearing seat 3, the roller 1 is sleeved on the outer surface of the roller drive shaft 2, the roller 1 is in contact with the belt surface, and the roller 1 rotates under the action of the belt friction force. The rotation of the roller 1 drives the roller drive shaft 2 to rotate synchronously. The connecting hole 4 is opened inside the roller drive shaft 2, and the sensor 5 is sleeved in the connecting hole 4 The inductive components inside the sensor 5 rotate synchronously with the roller drive shaft 2, and the roller bearing seat 3 is fixedly connected to the belt bracket by bolts. The roller 1 rotates with the belt conveyor under the friction of the belt, and the roller drive shaft 2 rotates synchronously with the roller 1. The sensor 5 is connected to the roller drive shaft 2 through the connecting hole 4, and the sensor 5 rotates synchronously with the roller 1. When working, the belt conveyor belt runs, and the roller 1 rotates under the friction of the belt, and the roller drive shaft 2 rotates synchronously with the roller 1. The sensor 5 rotates synchronously with the roller 1 through the connecting hole 4. When the belt conveyor operates normally, the real-time detection roller is always in a rotating state. When a belt emergency stop fault occurs, such as the transmission device coupling is disconnected, the belt is broken, or the drive roller shaft is broken, the detection roller stops rotating. At this time, the sensor 5 will issue a motor stop command to stop the motor urgently, and the subsequent processes will stop urgently. The belt conveyor operation detection roller structure is generally installed at the belt return surface of the belt conveyor head bracket.

[0019] In response to the problems existing in the prior art, the utility model provides a real-time detection roller structure for belt conveyor operation. During operation, the belt of the belt conveyor runs, and the roller 1 rotates under the action of the belt friction force. The roller drive shaft 2 rotates synchronously with the roller 1, and the sensor 5 rotates synchronously with the roller 1 through the connecting hole 4. When the belt conveyor operates normally, the real-time detection roller is always in a rotating state. When a belt emergency stop failure occurs, such as the transmission device coupling is disconnected, the belt is broken, or the transmission roller shaft is broken, the detection roller stops rotating. At this time, the sensor 5 will issue a motor stop command to stop the motor urgently, and the subsequent processes will be stopped urgently. The sensor 5 sends a fault signal to cut off the power to the belt conveyor motor and stop it, which can effectively avoid conveyor blockage, material leakage, conveyor crushing and other failures caused by belt conveyor coupling disconnection, belt breakage or transmission roller shaft breakage.

[0020] Working principle:

[0021] The first step is that when the belt conveyor is working, the belt runs, and the roller 1 rotates under the action of the belt friction force. The roller drive shaft 2 rotates synchronously with the roller 1, and the sensor 5 rotates synchronously with the roller 1 through the connecting hole 4. When the belt conveyor is operating normally, the real-time detection roller is always in a rotating state. When a belt emergency stop failure occurs, such as the transmission device coupling is disconnected, the belt is broken, or the transmission roller shaft is broken, the detection roller stops rotating. At this time, the sensor 5 will issue a motor stop command to stop the motor urgently, and the subsequent processes will be stopped urgently. The belt conveyor operation detection roller structure is generally installed on the belt return surface of the belt conveyor head bracket.

[0022] In the second step, the structure of the utility model can effectively detect the operating status of the belt conveyor in real time. The belt and the sensor 5 rotate synchronously, and the feedback signal is the normal operating status of the conveyor. When the coupling of the conveyor transmission device is disconnected, the transmission roller is broken, or the belt is broken, the belt stops suddenly. When the motor is still in operation, the detection roller stops rotating with the belt. At this time, the sensor 5 sends a motor stop command, the motor is powered off and stops, and the previous process stops urgently, effectively avoiding conveyor failures such as crushing, blocking, and leakage.

[0023] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
