Description

Technical Field

[0001] This utility model relates to the field of electronic belt scale technology, specifically to a device for precise adjustment of the chain code position of an electronic belt scale. Background Technology

[0002] Chain codes for electronic belt scales are an important tool used in the calibration process. They are standard chain weights used to verify the accuracy of electronic belt scales. They are usually designed to be placed flat on the belt and roll as the belt moves, thus simulating the movement of materials on the belt. The chain code calibration device for coal conveying electronic belt scales is an important part of belt scale calibration. Accurate chain code calibration can greatly improve work efficiency and reduce the labor intensity of calibration work.

[0003] The existing devices only use wire hooks to fix the chain codes. The placement and tightness of the chain codes depend solely on the experience of the staff. This results in poor reproducibility of the chain code placement position and low accuracy of chain code verification, thus reducing the precision of chain code placement and failing to meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a device for precise adjustment of the chain code position of an electronic belt scale, so as to solve the problems mentioned in the background art that the existing devices only fix the chain code with steel wire hooks, and the chain code hanging position and tightness rely solely on the experience of the operator. This results in poor reproducibility of the chain code hanging position, low accuracy of chain code verification, reduced chain code position precision, and failure to meet the usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise adjustment device for the position of a chain code on an electronic belt scale, comprising a chain code body, wherein hanging holes are symmetrically arranged at both ends of the chain code body, and the hanging holes are L-shaped; turnbuckles are symmetrically arranged at both ends of the chain code body, the turnbuckles are matched with the hanging holes, and the turnbuckles are detachably connected to the chain code body.

[0006] By installing turnbuckles, the hanging points and hooks at both ends of the belt scale chain code are modified, changing from single hanging points to double hanging points and hooks to turnbuckles. The double hanging points improve the chain code's stability and safety, and also allow for adjustment of the chain code's swing position, improving its positional accuracy. Replacing the hooks with turnbuckles utilizes their adjustable distance to accurately position the beginning and end of the chain code, further enhancing the accuracy of chain code placement.

[0007] Preferably, the turnbuckle includes a bolt body, a first pull rod, and a second pull rod. Both the first pull rod and the second pull rod are movably connected to the bolt body. One end of the second pull rod is provided with a hook, which is hooked to the bolt body.

[0008] Preferably, the bolt body has a connecting cavity in the middle, and the two ends of the connecting cavity are threaded holes with opposite threads.

[0009] Preferably, both the first and second pull rods have external threads on one end of their outer walls, and the external threads on the first and second pull rods are arranged in opposite directions. The first and second pull rods are threadedly connected to the corresponding threaded holes.

[0010] Preferably, both ends of the outer side of the bolt body are provided with a release bolt, the release bolt is threadedly connected to the bolt body, and the release bolt abuts against the first tie rod or the second tie rod.

[0011] Preferably, a limiting strip is provided at the hook, one end of the limiting strip is fixedly connected to the hook, and the other end of the limiting strip is provided with a through hole, through which the free end of the hook passes and is fastened to the limiting strip.

[0012] Preferably, a hanging ring is integrally provided at the end of the first pull rod away from the bolt body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model device modifies the hanging points and hooks at both ends of the belt scale chain code by setting turnbuckles, changing the original single hanging point to a double hanging point and the hook to a turnbuckle. The double hanging point can improve the chain code's firmness and safety, and can also adjust the chain code's swing position to improve the repeatability of the chain code's position. The hook is changed to a turnbuckle, which utilizes its adjustable distance to achieve accurate positioning of the chain code's beginning and end positions, improving the accurate reproduction of the chain code's hanging position, thereby greatly improving the accuracy, reliability, and safety of chain code verification.

[0015] 2. This utility model device, through the setting of a limiting strip, a loosening bolt, and a through hole, rotates the loosening bolt so that one end of it is in tight contact with the first and second pull rods, thereby limiting the contact between the first and second pull rods and ensuring the stability of the overall structure of the turnbuckle. One end of the second pull rod passes through the through hole and connects to the limiting strip, forming a closed loop with the second pull rod and preventing the second pull rod from falling off the chain code.

The turnbuckles 3 are detachably connected to the chain code body 1.

[0022] The turnbuckle 3 includes a bolt body 4, a first pull rod 6, and a second pull rod 7. Both the first pull rod 6 and the second pull rod 7 are movably connected to the bolt body 4. The first pull rod 6 and the second pull rod 7 are located on both sides of the bolt body 4. The end of the first pull rod 6 facing away from the bolt body 4 is integrally provided with a hanging ring for connecting other components. One end of the second pull rod 7 is provided with a hook, which is hooked to the bolt body 4. A connecting cavity is opened in the middle of the bolt body 4. The two ends of the connecting cavity are provided with threaded holes 5, and the threads of the threaded holes 5 are arranged in opposite directions. One end of the outer wall of the first pull rod 6 and the second pull rod 7 is provided with external threads 10, and the external threads 10 on the first pull rod 6 and the second pull rod 7 are arranged in opposite directions. The first pull rod 6 and the second pull rod 7 are threadedly connected to the corresponding threaded holes 5.

[0023] In use: Connect the second pull rod 7 to both ends of the chain code body 1, and connect the first pull rod 6 to the electronic belt scale body. The chain code is fixed with double hanging points at both ends to improve the chain code's firmness. Rotating the first pull rod 6 or the second pull rod 7 can adjust the length of the turnbuckle 3. As the length of the turnbuckle 3 changes, the installation position of the chain code is changed, realizing accurate positioning of the beginning and end positions of the chain code, improving the accurate reproduction of the chain code's hanging position, and improving the accuracy, reliability, and safety of chain code verification.

[0024] Please see Figure 2 and Figure 3Two loosening bolts 9 are provided at both ends of the outer side of the bolt body 4. The loosening bolts 9 are threaded to the bolt body 4.

[0025] A limit strip 8 is provided at the hook, and a through hole 11 is provided on the limit strip 8. The free end of the hook passes through the through hole 11 and is fastened to the limit strip 8. Rotating the release bolt 9 makes one end of it tightly contact the first pull rod 6 and the second pull rod 7, limiting the contact between the first pull rod 6 and the second pull rod 7, ensuring the stability of the overall structure of the turnbuckle 3. One end of the second pull rod 7 passes through the through hole 11 and is connected to the limit strip 8, forming a closed loop for the second pull rod 7, preventing the second pull rod 7 from falling off the chain code.

[0026] Working principle: The second pull rod 7 is connected to both ends of the chain code body 1. The free end of the hook passes through the through hole 11 and is connected to the limiting strip 8 to prevent the second pull rod 7 from falling off the chain code. The first pull rod 6 is connected to the electronic belt scale body. The chain code is fixed by double hanging points at both ends to improve the stability of the chain code. Rotating the first pull rod 6 or the second pull rod 7 can adjust the length of the turnbuckle 3. Rotating the loosening bolt 9 makes one end of it tightly contact the first pull rod 6 and the second pull rod 7 to limit the contact between the first pull rod 6 and the second pull rod 7. As the length of the turnbuckle 3 changes, the installation position of the chain code is changed, so as to accurately position the beginning and end of the chain code and improve the accuracy of the chain code hanging position.
