Description

Technical Field

[0001] This utility model relates to the field of belt scale technology, and in particular to a belt scale inspection device with adjustable weight height. Background Technology

[0002] A belt scale is a continuous dynamic weighing device installed on a conveyor frame. It measures the instantaneous flow rate and cumulative weight of materials on the conveyor belt in real time. It consists of a weighing sensor, a speed measuring device, and an integrator. It calculates the flow rate by detecting the weight of the material and the belt speed. It is widely used in bulk material metering in industries such as mining, ports, and power.

[0003] To ensure the accuracy of belt scale measurements, regular calibration is essential. Existing belt scale inspection devices often use fixed weights or simple adjustment mechanisms for calibration. However, these devices cannot simulate the different load conditions experienced by the belt scale during actual production, and therefore cannot fully verify the scale's measurement accuracy and stability. Furthermore, in existing devices, the direct contact between the weights and the belt can easily generate friction, which may affect the accuracy of the inspection results. In addition, the inconvenience of replacing weights often increases the complexity and workload of the inspection process. Utility Model Content

[0031] The weight mechanism 300 includes a mounting frame 303, which is fixedly mounted on the bottom end of the frame 211. The mounting frame 303 is designed to support the rotation of the first transmission wheel 310, and one end of the mounting frame 303 is rotatably connected to the first transmission wheel 310.

[0032] Example 2:

[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the bracket 100 has a through hole 205, through which the steel wire rope 207 passes. A first motor 208 is fixedly installed on the bracket 100. The first motor 208 is horizontally positioned, and a second shaft 206 is fixedly installed on the shaft end of the first motor 208.

[0035] The through hole 205 is square in shape and is designed to allow the wire rope 207 to pass through. The first motor 208 has forward and reverse rotation functions. The first motor 208, together with the second shaft 206, facilitates the rotation of the take-up roller 202. The second shaft 206 is used to support the installation of the take-up roller 202.

[0036] Specifically, the second shaft 206 is cylindrical, and one end of the second shaft 206 is fixedly connected to the take-up roller 202.

[0037] The second shaft 206 is used to receive the installation of the take-up roller 202, and the take-up roller 202 is used to take up the wire rope 207.

[0038] Specifically, limit wheels 201 are installed at both ends of the frame 211, and limit grooves 210 are opened on the inner wall of the bracket 100, so that the limit wheels 201 roll in the limit grooves 210.

[0039] There are four limit wheels 201. The limit wheels 201 are set to roll within the limit groove 210. The limit groove 210 is a strip groove. There are two limit grooves 210. The limit grooves 210 are set to support the rolling of the limit wheels 201.

[0040] Specifically, a pointer 213 is fixedly installed at one end of the frame 211. The pointer 213 is L-shaped. A scale 209 is fixedly installed on the surface of the bracket 100. The scale 209 is set vertically.

[0041] The pointer 213 is L-shaped. The setting of the pointer 213, together with the scale 209, makes it easy to control the height of the weight mechanism 300.

[0042] Specifically, a second motor 306 is fixedly installed on the inner wall of the frame 211. The second motor 306 is horizontally positioned, and a rotating rod 305 is fixedly installed on the shaft end of the second motor 306.

[0043] The second motor 306 is a variable speed motor. The second motor 306 is configured to drive the rotating rod 305 to rotate, and the rotating rod 305 is configured to drive the second transmission wheel 304 to rotate.

[0044] Example 3:

[0045] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, the rotating rod 305 is set horizontally and is cylindrical in shape. One end of the rotating rod 305 is rotatably connected to the inner wall of the frame 211.

[0047] The rotating rod 305 is designed to drive the second transmission wheel 304 to rotate.

[0048] Specifically, a second transmission wheel 304 is fixedly installed on the rotating rod 305, and a track 309 is meshed with the first transmission wheel 310 on the second transmission wheel 304.

[0049] The second transmission wheel 304, in conjunction with the first transmission wheel 310, is used to engage with the track 309. When the second transmission wheel 304 rotates, it drives the first transmission wheel 310 to rotate as well.

[0050] Specifically, a limiting disk 302 is fixedly installed on the side of the first conveyor wheel 310. The limiting disk 302 is vertically arranged and is disc-shaped.

[0051] By setting a limit plate 302, the weight body 301 on the insertion rod 308 is limited.

[0052] Specifically, a rod 308 is fixedly installed on the side of the limiting plate 302. The cross-sectional shape of the rod 308 is cross-shaped. A weight body 301 is inserted into the rod 308. A threaded rod 311 is fixedly installed at one end of the rod 308. A fixing cap 307 is threadedly connected to the threaded rod 311. There are two fixing caps 307.

[0053] The insertion rod 308 is used to insert the weight body 301. The weight body 301 is used to detect the belt scale. The threaded rod 311 is used to thread the fixing cap 307. By setting two fixing caps 307, it is easy to thread them onto the threaded rod 311. This serves to limit the movement of the weight body 301 on the insertion rod 308 and prevent the weight body 301 from falling off the insertion rod 308. At the same time, the use of two threaded fixing caps 307 can effectively reduce the risk of the fixing cap 307 falling off the threaded rod 311.

[0054] When in use, move the inspection device to the belt scale and install it directly above the belt scale. Then, according to the inspection requirements, remove the fixing cap 307, select the appropriate number of weight bodies 301, and insert them into the insertion rod 308. Then, thread the fixing cap 307 onto the threaded rod 311 to prevent the weight body 301 from falling off the insertion rod 308. At the same time, by using two fixing caps 307, the risk of the fixing cap 307 falling off the threaded rod 311 can be effectively reduced.

[0055] After the weight body 301 is installed, start the belt and run it unloaded for three minutes, record the zero point value of the instrument, then turn off the belt conveyor mechanism and start the first motor 208. The first motor 208 drives the take-up roller 202 to rotate through the second shaft 206. When the take-up roller 202 rotates, it will release the wire rope 207. As the wire rope 207 is released, the frame 211 will move vertically downward through the limit wheel 201 and the limit slide 210. When the frame 211 moves downward, it will drive the weight body 301 to move vertically downward. With the help of the pointer 213 and the scale 209, the weight body 301 will move to the appropriate height position.

[0056] After the height of the weight body 301 is adjusted, the belt scale is started and the conveyor belt begins to run. At the same time, the second motor 306 is started. The second motor 306 drives the rotating rod 305 to rotate. When the rotating rod 305 rotates, it drives the limiting plate 302 to rotate through the second conveyor wheel 304, the track 309 and the first conveyor wheel 310. When the limiting plate 302 rotates, it drives the weight body 301 to rotate through the insertion rod 308. The rotation speed of the weight body 301 is the same as the transmission speed of the conveyor belt to avoid friction between the weight body 301 and the conveyor belt, which would affect the test data.

[0057] During the conveyor belt operation, the belt scale measures the weight of the weights and records the data. During the testing process, the height of the weights can be adjusted through the above operations to simulate different loads. At the same time, the number or weight of the weights can be gradually increased or decreased to simulate the situation from no load to full load, which is convenient for testing the measurement accuracy of the belt scale.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
