Description

Technical Field

[0001] This utility model relates to the field of belt scale technology, specifically to an automatic switching control device for belt scale platform failure. Background Technology

[0002] A belt scale is an automated weighing instrument that can continuously and dynamically weigh bulk materials without interrupting the movement of the conveyor belt. It is widely used in industries such as power, metallurgy, and mining. Its core components include a weighing bridge, sensors, speed measuring devices, and control instruments. By detecting the belt load and speed signals, it outputs instantaneous flow rate and cumulative weight through integration calculations, replacing the traditional static batch weighing method.

[0003] Belt scales consist of multiple weighing platforms. Traditional belt scales do not have the function of automatically switching between weighing platforms. When a single weighing platform fails, the entire belt scale needs to be shut down for a long time for maintenance, which seriously affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic switching control device for belt scale platform failures, which solves the problem in the prior art where, when a single platform fails, the entire belt scale needs to be shut down for a long time for maintenance, which seriously affects production efficiency.

[0005] This utility model provides the following technical solution: an automatic switching control device for belt scale platform failure, comprising a belt scale platform body, and further comprising:

[0006] Support reference frame;

[0007] An automatic switching mechanism is installed on a support reference frame and is used to automatically switch the main body of the belt scale that is malfunctioning.

[0008] A convenient disassembly and assembly mechanism is provided on the automatic switching mechanism. The convenient disassembly and assembly mechanism is used to improve the efficiency of disassembly and maintenance of the main body of the belt scale.

[0009] The automatic switching mechanism includes a first frame and a second frame. Both the first frame and the second frame are fixedly installed on the side of the supporting reference frame. Track rods are fixedly installed on the inner walls of both the first frame and the second frame. Lead screws are rotatably connected to the inner walls of both the first frame and the second frame. Lifting seats are provided on the outer walls of the track rods and the lead screws.

[0010] As a preferred embodiment of the above technical solution, a bottom support frame is fixedly installed at the bottom of the first frame and the second frame, and a servo motor is fixedly installed at the bottom of the bottom support frame.

[0011] As a preferred embodiment of the above technical solution, the output shaft of the servo motor extends into the inner cavity of the base support and is fixedly connected to a gear one. The gear one is fixedly installed at the bottom of one of the lead screws, and a gear four is fixedly installed at the bottom of the other lead screw.

[0012] As a preferred embodiment of the above technical solution, the bottom of the inner cavity of the bottom support frame is rotatably connected with gear two and gear three, and gear one, gear two, gear three and gear four mesh with each other in sequence.

[0013] As a preferred embodiment of the above technical solution, the convenient disassembly and assembly mechanism includes a support block, which is fixedly installed on the side of the lifting seat. A groove is provided on the top of the support block, and a pin is movably inserted into the inner cavity of the groove. The main body of the belt scale platform is fixedly installed on the top of the pin.

[0014] As a preferred embodiment of the above technical solution, both the support block and the pin are provided with through holes, and telescopic clips are movably inserted into the through holes.

[0015] As a preferred embodiment of the above technical solution, the telescopic clip includes a first plug and a second plug.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, through the overall design of the automatic switching mechanism, can control the servo motor to work when a single weighing platform fails. Through the transmission of gear one, gear two, gear three, and gear four, it drives two lead screws to rotate in opposite directions, thereby raising one lifting seat and lowering the other lifting seat. In this way, the main body of the spare belt scale can be replaced with the main body of the faulty belt scale. A short shutdown is all that is needed for the switch, ensuring production efficiency.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic switching control device for belt scale platform failures, including a belt scale platform body 11, and further comprising:

[0025] Support reference frame 1;

[0026] Automatic switching mechanism 2 is installed on the support reference frame 1. Automatic switching mechanism 2 is used to automatically switch the main body 11 of the belt scale that is faulty.

[0027] The convenient disassembly and assembly mechanism 3 is set on the automatic switching mechanism 2. The convenient disassembly and assembly mechanism 3 is used to improve the efficiency of disassembly and maintenance of the main body 11 of the belt scale platform.

[0028] The automatic switching mechanism 2 includes a first frame 21 and a second frame 22. Both the first frame 21 and the second frame 22 are fixedly installed on the side of the supporting reference frame 1. Track rods 211 are fixedly installed on the inner walls of the first frame 21 and the second frame 22. Lead screws 213 are rotatably connected to the inner walls of the first frame 21 and the second frame 22. Lifting seats 212 are provided on the outer walls of the track rods 211 and the lead screws 213. When the main body 11 of the belt scale platform is damaged in use, the servo motor 25 is controlled to work, which can drive the two lead screws 213 to rotate in opposite directions, thereby raising one lifting seat 212 and lowering the other lifting seat 212. In this way, the spare belt scale platform main body 11 can replace the faulty belt scale platform main body 11. The switching can be done with a short stop, ensuring production efficiency.

[0029] As one implementation method in this embodiment, such as Figure 2 As shown, a base support frame 23 is fixedly installed at the bottom of frame 1 21 and frame 22. A servo motor 25 is fixedly installed at the bottom of the base support frame 23. The base support frame 23 is used to support the servo motor 25 and other structures. The servo motor 25 is used to provide power for automatic switching.

[0030] As one implementation method in this embodiment, such as Figure 2 As shown, the output shaft of the servo motor 25 extends into the inner cavity of the base support 23 and is fixedly connected to a gear 24. The gear 24 is fixedly installed at the bottom of one of the lead screws 213, and a gear 28 is fixedly installed at the bottom of the other lead screw 213. The servo motor 25 can be controlled to rotate by the gear 24 driving its lead screw 213.

[0031] As one implementation method in this embodiment, such as Figure 2 As shown, gear 26 and gear 37 are rotatably connected to the bottom of the inner cavity of the base support frame 23. Gear 1 24, gear 26, gear 3 27 and gear 4 28 mesh sequentially. When the servo motor 25 drives its lead screw 213 to rotate through gear 1 24, it can drive another lead screw 213 to rotate in the opposite direction through the transmission of gear 2 26, gear 3 27 and gear 4 28. This enables the function of replacing the faulty belt scale platform body 11 with the spare belt scale platform body 11.

[0032] As one implementation method in this embodiment, such as Figure 3 As shown, the convenient disassembly and assembly mechanism 3 includes a support block 31, which is fixedly installed on the side of the lifting seat 212. A groove 32 is provided on the top of the support block 31, and a pin 33 is movably inserted into the inner cavity of the groove 32. The main body 11 of the belt scale platform is fixedly installed on the top of the pin 33. By inserting and removing the pin 33 inside the groove 32, the function of quickly disassembling and maintaining the main body 11 of the belt scale platform can be realized.

[0033] As one implementation method in this embodiment, such as Figure 3 As shown, both the support block 31 and the pin 33 have through holes 34. A telescopic clip 35 is movably inserted into the through hole 34. In the initial state, the telescopic clip 35 is inserted into the through hole 34 of the support block 31 and the pin 33, locking the pin 33 inside the support block 31 and maintaining the installation state of the belt scale platform body 11.

[0034] As one implementation method in this embodiment, such as Figure 4As shown, the telescopic clamp 35 includes a first insert 351 and a second insert 352. A T-shaped rod 353 is fixedly connected to the end of the first insert 351, and a sliding rod 354 is fixedly connected to the end of the second insert 352. The sliding rod 354 is slidably connected to the T-shaped rod 353. An elastic element 355 is fixedly installed at the end of the T-shaped rod 353. The end of the elastic element 355 away from the T-shaped rod 353 is fixedly installed at the end of the second insert 352. The belt scale can only be disassembled after the telescopic clamp 35 is disassembled. When disassembling the telescopic clip 35, the main body 11 can push the first plug 351 and the second plug 352 toward each other, causing the slide bar 354 to slide on the T-shaped bar 353, while compressing the elastic element 355. When resetting and reconnecting, align the first plug 351 and the second plug 352 with the through hole 34, and then release them. Through the elastic force of the elastic element 355, the first plug 351 and the second plug 352 will move away from each other and be inserted into the inside of the through hole 34, thus completing the installation.

[0035] Working principle: When the main body 11 of the belt scale is damaged during use, the servo motor 25 is activated. It drives the lead screw 213 through gear 24 to rotate. At this time, gear 24 drives the other lead screw 213 to rotate in the opposite direction through gears 26, 27, and 28. This causes one lifting seat 212 to rise and the other lifting seat 212 to fall. This allows the spare main body 11 of the belt scale to replace the faulty main body 11. If the main body 11 of the belt scale needs to be disassembled for maintenance, the telescopic clip 35 is first disassembled. By inserting and unplugging the pin 33 inside the groove 32, the main body 11 of the belt scale can be quickly disassembled and assembled.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
