Technical Field

[0001] The utility model relates to the field of on-line monitoring of equipment, and particularly to an on-line monitoring device and system for a belt weighing scale. Background Art

[0002] Belt conveyors are widely used in various mine sites. Materials are transported from the working face to the designated position through the belt conveyor. It has a simple structure and high efficiency. It is a continuous conveying machine with a flexible conveyor belt as the material-carrying and traction member. An endless conveyor belt surrounds the driving roller and the redirecting roller. The upper and lower branches between the two rollers are each supported by a number of idlers. The material is placed on the upper branch. The conveyor belt and the material are dragged by the friction between the driving roller and the belt to run. It is suitable for transporting bulk materials and packaged goods in horizontal and inclined directions, and can also be used for the assembly line with certain technological operations. It has a simple structure, stable and reliable operation, strong adaptability to materials, large conveying capacity, low power consumption, and wide application.

[0003] In order to weigh the materials on the belt conveyor, the prior art usually installs a weighing bracket under the belt conveyor and weighs the materials in real time through a weighing sensor. However, in order to ensure the stability of the material weighing by the belt weighing scale, it is necessary to ensure the stable operation of the belt conveyor and the materials should be within the weighing range. This requires strengthening the daily maintenance and management of the staff.

[0004] In the prior art, the daily management of the belt weighing scale mainly focuses on the inspection of the scale body. The inspection personnel go to the equipment installation site to inspect the equipment and check the operating status of the equipment. The equipment inspection is generally carried out once a day. However, during the actual operation of the equipment, the operating status of the speed sensor of the belt weighing scale and the operating status of the belt cannot be monitored. And the long interval of manual inspection is likely to cause inaccurate weighing. Therefore, how to reduce the occurrence of inaccurate weighing caused by the long interval of manual inspection and realize the real-time monitoring of the operation of the belt weighing scale is an urgent problem to be solved at present.

Specific embodiments

[0019] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.

[0020] As Figure 1 shown, in order to achieve the above object, the embodiment of the present utility model provides a structural schematic diagram of an on-line monitoring device and system for a belt weighing scale, which consists of Figure 1 it can be seen that:

[0021] The present utility model provides an on-line monitoring device and system for a belt weighing scale, including a belt weighing scale unit 1, an instrument unit 2 and a computer unit 3; the belt weighing scale unit 1 includes a belt 101, a bracket 102, an idler 103, a pressure sensor 104 and a speed sensor 105; the instrument unit 2 processes the signals collected by the pressure sensor 104 and the speed sensor 105 and transmits them to the computer unit 3; the instrument unit 2 is connected to the computer unit 3 through an RS485 communication serial port.

[0022] As Figure 2 shown, in this embodiment, the instrument unit 2 includes a weighing data processing module 201, a speed data processing module 202 and a parameter display module 203.

[0023] In this embodiment, the bracket 102 is used to support the idler 103.

[0024] In this embodiment, the idler 103 is in contact with the belt 101, and when the belt weighing scale unit 1 works, the linear speed of the idler 103 is the same as that of the belt 101.

[0025] In this embodiment, the pressure sensor 104 is installed on the bracket 102.

[0026] In this embodiment, the speed sensor 105 is in contact with the belt 101, and when the belt weighing scale unit 1 works, the linear speed of the speed sensor 105 is the same as that of the belt 101.

[0027] As Figure 3 shown, in this embodiment, the computer unit 3 displays in real time the instantaneous amount 301 of belt-metered material, the cumulative amount 302 of material, and the belt running speed 303.

[0028] In this embodiment, the parameter display module 203 is an LCD1602 liquid crystal display screen for displaying in real time the belt metering parameters.

[0029] The working principle of the above embodiment is as follows:

[0030] During operation, the material is conveyed by the belt 101. Due to the pressure generated by the material and the friction between the belt 101 and the idler 103, the idler 103 makes a rotational motion, and its linear speed is the same as that of the belt 101. The idler 103 is supported by the bracket 102, and the pressure sensor 104 is installed on the bracket 102. Under the action of the material pressure, the pressure sensor 104 deforms, thereby generating an electrical signal. The pressure sensor 104 transmits the generated electrical signal to the weighing data processing module 201 of the instrument unit 2 for data processing; the speed sensor 105 is in contact with the belt 101. When the belt scale unit 1 is working, the speed sensor 105 has the same linear speed as the belt 101, and the speed sensor 105 transmits the collected signal to the speed data processing module 202 of the instrument unit 2 for data processing.

[0031] The parameter display module 203 of the instrument unit 2 displays in real time the belt metering parameters. After processing the collected weight signal and speed signal, it is transmitted to the computer unit 3 through a data transmission line. The computer unit 3 displays in real time the instantaneous amount 301 of belt-metered material, the cumulative amount 302 of material, and the belt running speed 303, thereby realizing the real-time monitoring of the belt running speed and the material weight of the belt weigher, improving the degree of industrial fine management, and providing accurate, timely, and effective data support.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
