Description

Technical Field

[0001] This utility model relates to the field of chain code verification technology, and more specifically, to a chain code verification device. Background Technology

[0002] Belt conveyors are common material handling equipment, widely used in industries such as mining, metallurgy, chemical, power, and construction. Belt scales, installed on belt conveyors, calculate material flow and cumulative volume by measuring the weight of the material on the belt and the belt speed.

[0003] Chain code verification is a method used to calibrate and verify the accuracy of belt scales. Belt scales are mainly used to continuously measure the weight of materials transported on conveyor belts. Chain code verification uses a series of standard chain codes of known weight (usually a chain with a standard weight) placed on the belt scale and run to simulate the weight of the actual material, thereby checking the measurement accuracy of the belt scale.

[0004] During calibration, the chain codes are brought into contact with the surface of the belt conveyor, causing the belt to rotate and simulate material transport. Currently, the chain code installation process is cumbersome. When the chain code height needs adjustment, it must be repeatedly disassembled and reinstalled to achieve the desired height. This entire adjustment process is labor-intensive and time-consuming, resulting in low calibration efficiency. After calibration, the chain codes must be removed and stored separately before continued use, leading to unsatisfactory performance.

[0005] Therefore, it is necessary to provide a chain code verification device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a chain code verification device to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A chain code verification device for verifying belt scales on a belt conveyor, comprising a chain code, and further comprising:

[0009] Two supports are mounted on the belt conveyor;

[0010] A screw is rotatably mounted on the bracket, and a connecting seat is threaded onto the screw. A limiting plate is provided on the connecting seat.

[0011] Both the transmission mechanism and the slide bar are mounted on the bracket. The slide bar moves through the limiting plate, and the transmission mechanism is used to drive the screw to rotate.

[0012] Two hanging rods are respectively set at both ends of the chain code, and the end of the hanging rod away from the chain code is detachably connected to the connecting seat.

[0013] Furthermore, the connecting seat is provided with a mounting plate, the mounting plate is provided with a hook, and the end of the hanging rod is provided with a hanging ring that matches the hook.

[0014] Furthermore, the mounting plate is detachably provided with a fixing plate connected to the hook;

[0015] The mounting plate is provided with multiple screw holes, and the fixing plate is provided with fixing holes that correspond to and are adapted to the screw holes.

[0016] Furthermore, the transmission mechanism includes:

[0017] A transmission seat is disposed on the top of the bracket, and a rotating rod is rotatably disposed on the transmission seat. A first bevel gear is disposed at one end of the rotating rod located inside the transmission seat.

[0018] The upper end of the screw extends into the transmission seat and is provided with a second bevel gear that meshes with the first bevel gear.

[0019] Furthermore, the bracket has an opening, and an indicator rod is slidably disposed in the opening, the indicator rod being connected to the limiting plate;

[0020] The outer wall of the bracket is provided with a scale bar, and the indicator rod is provided with a pointer.

[0021] Furthermore, the belt conveyor is equipped with a slide rail, and the support is equipped with a slide block that is slidably connected to the slide rail;

[0022] The slide rail has multiple limiting holes, and the slide block is threaded with fastening bolts that are compatible with the limiting holes.

[0023] Furthermore, a handle is provided at the end of the rotating rod away from the transmission seat.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This solution involves mounting both ends of the chain code onto connecting seats on two brackets. A transmission mechanism, working in conjunction with a screw, raises or lowers the connecting seats and the chain code, allowing for easy adjustment of the chain code's height. Ultimately, the chain code is positioned on the conveyor belt to simulate material movement, and calibration is achieved using a belt scale at the bottom of the belt. During calibration, the chain code height can be adjusted as needed, making the operation simple and quick. It eliminates the need for repeated manual disassembly and adjustment, saving significant manpower and time, and greatly improving calibration efficiency, thus demonstrating high practicality.

[0026] Furthermore, after verification, the chain code can be raised so as not to affect the normal conveying of the belt conveyor, which can reduce the frequency of disassembling the chain code and has a good effect. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-6 A chain code verification device for verifying a belt scale on a belt conveyor 1, comprising a chain code 2, and further comprising:

[0037] Two brackets 3 are mounted on the belt conveyor 1;

[0038] The screw 4 is rotatably mounted on the bracket 3. A connecting seat 5 is threaded onto the screw 4, and a limiting plate 6 is provided on the connecting seat 5.

[0039] The transmission mechanism 7 and the slide bar 8 are both mounted on the bracket 3. The slide bar 8 moves through the limiting plate 6. The transmission mechanism 7 is used to drive the screw 4 to rotate.

[0040] Two hanging rods 9 are respectively set at both ends of the chain code 2, and the end of the hanging rod 9 away from the chain code 2 is detachably connected to the connecting seat 5.

[0041] In use, the two ends of the chain code 2 are respectively installed on the connecting seats 5 of the two brackets 3. Then, the screw 4 is driven to rotate through the transmission mechanism 7. Since the sliding rod 8 and the limiting plate 6 restrict the rotation of the connecting seat 5, the rotation of the screw 4 will cause the connecting seat 5 to move up or down. The connecting seat 5 will slide along the sliding rod 8 with the limiting plate 6. The raising and lowering of the connecting seat 5 will cause the chain code 2 to rise or fall, thus making it easy to adjust the height of the chain code 2. Finally, the chain code 2 is placed on the belt of the belt conveyor 1 and rolls with the movement of the belt. At this time, the chain code 2 can simulate the movement of materials, and its calibration can be achieved by the belt scale at the bottom of the belt. During calibration, the height of the chain code 2 can be adjusted as needed. The operation is simple and quick, without the need for repeated manual disassembly and reassembly of the chain code 2 to achieve the purpose of adjustment, saving a lot of manpower and time, significantly improving calibration efficiency, and making it highly practical. After calibration, the chain code 2 can be raised so as not to affect the normal conveying of the belt of the belt conveyor 1, reducing the frequency of disassembly of the chain code 2, and the use effect is good.

[0042] When installing chain code 2, the hanging rod 9 of chain code 2 can be connected to the connecting seat 5. When removing chain code 2, simply separate the hanging rod 9 of chain code 2 from the connecting seat 5. This completes the installation and removal of chain code 2. The operation is simple, convenient, time-saving and labor-saving.

[0043] For preferred options, please refer to [link / reference]. Figure 1-2 and Figure 5 The connecting seat 5 is equipped with a mounting plate 10, and the mounting plate 10 is equipped with a hook 11. The end of the hanging rod 9 is equipped with a hanging ring 12 that matches the hook 11. This design allows the chain code 2 to be installed by hooking the hanging ring 12 on the hanging rod 9 of the chain code 2 onto the hook 11 of the mounting plate 10. Figure 1-2 As shown in the diagram, chain code 2 can now be connected to connector 5, thus completing the installation of chain code 2. Similarly, when removing chain code 2, simply detach the hanging ring 12 from the hook 11.

[0044] For preferred options, please refer to [link / reference]. Figure 1-2 and Figure 5 The mounting plate 10 is detachably provided with a fixing plate 13 connected to the hook 11;

[0045] The mounting plate 10 is provided with a plurality of screw holes 14, and the fixing plate 13 is provided with fixing holes that correspond to and are adapted to the screw holes 14.

[0046] This design aligns the fixing holes of the fixing plate 13 with the screw holes 14 of the mounting plate 10, allowing the fixing plate 13 to be fixed to the mounting plate 10 using bolts, thus completing the installation of the hook 11. Similarly, the fixing plate 13 can be removed to detach the hook 11, enabling inspection or replacement of the hook 11. Different hooks 11 can be selected according to different chain code 2 installation requirements, making it widely applicable. Furthermore, when the position of the chain code 2 needs adjustment, the fixing plate 13 and hook 11 can be fixed to different positions on the mounting plate 10 for convenient adjustment of the chain code 2, offering high flexibility and good performance.

[0047] For preferred options, please refer to [link / reference]. Figure 1 and Figure 5-6 The transmission mechanism 7 includes:

[0048] A transmission seat 71 is located on the top of the bracket 3. A rotating rod 72 is rotatably mounted on the transmission seat 71. A first bevel gear 73 is mounted on one end of the rotating rod 72 located inside the transmission seat 71.

[0049] The upper end of the screw 4 extends into the transmission seat 71 and is provided with a second bevel gear 74 that meshes with the first bevel gear 73.

[0050] Specifically, rotating the rotating rod 72 will drive the first bevel gear 73 to rotate, and the rotation of the first bevel gear 73 will drive the second bevel gear 74 and the screw 4 to rotate. The rotation of the screw 4 will drive the connecting seat 5 to move in the vertical direction.

[0051] A handle 23 is provided at the end of the rotating rod 72 away from the transmission seat 71. The rotating rod 72 can be rotated by turning the handle 23, which makes it more convenient for the staff to operate.

[0052] For preferred options, please refer to [link / reference]. Figure 1 and Figure 4-5 The bracket 3 has a through-hole 15, and an indicator rod 16 is slidably disposed in the through-hole 15. The indicator rod 16 is connected to the limiting plate 6.

[0053] The outer wall of the bracket 3 is provided with a scale bar 17, and a pointer 18 is provided on the indicator rod 16.

[0054] With this design, when the connecting seat 5 moves vertically, the limiting plate 6 will drive the indicator rod 16 to move up and down along the through hole 15. The indicator rod 16 will drive the pointer 18 to move vertically, and the pointer 18 will point to different positions on the scale bar 17. This allows the moving height of the connecting seat 5 and the chain code 2 to be seen intuitively, making it easier for staff to make adjustments.

[0055] For preferred options, please refer to [link / reference]. Figure 1 and Figure 3 The belt conveyor 1 is equipped with a slide rail 19, and the support 3 is equipped with a slide block 20 that is slidably connected to the slide rail 19;

[0056] The slide rail 19 has multiple limiting holes 21, and the slide block 20 is threaded with fastening bolts 22 that are compatible with the limiting holes 21.

[0057] This design allows the slide block 20 to slide along the slide rail 19 after the fastening bolt 22 is loosened to disengage it from the limiting hole 21. This enables the bracket 3 to move horizontally, allowing adjustment of the distance between the two brackets 3, i.e., the distance between the two connecting seats 5. This adjustment is suitable for chain codes 2 of different lengths, facilitating verification of chain codes 2 of different specifications and providing strong applicability. After adjustment, the fastening bolt 22 is screwed into the corresponding limiting hole 21 to fix the slide block 20 and the bracket 3.
