[0002] The traditional belt scale hanging weight verification device needs to hang the weight manually, which is dangerous and difficult to improve the working efficiency of the belt scale hanging weight verification.

[0003] Based on this, the prior art (CN214667230U) proposes an automatic hanging code verification mechanism for a belt scale. When the belt scale needs to be calibrated, the winch drives the wire rope to retract through the winding roller, and pulls the balance bar toward one side of the rotating shaft. According to the lever principle, when the force arm on one side of the balance bar is smaller than the force arm on one side of the verification rod, the verification rod will rotate downward and fall into the verification bracket, and the verification bracket will then transfer the force it is subjected to to the weighing sensor, and then perform the verification operation.

[0004] The prior art (CN210108508U) proposes an electronic belt scale hanging weight calibration device. During calibration, the rotating device is operated to make the rotating shaft drive the support hook to rotate downward, and the calibration rod is placed on the calibration bracket to realize the hanging weight calibration of the electronic belt scale; after the calibration is completed, the rotating device is operated to make the rotating shaft drive the support hook to rotate and reset, and the calibration rod is lifted up again.

[0033] like Figure 1-2 As shown, the utility model provides a device for checking the weight hanging on a belt scale, comprising a rotating component 1, a plurality of frames 2 and a plurality of scale frames 3. In this embodiment, there is a rotating component 1, two frames 2 and two scale frames 3, and the two scale frames 3 are arranged between the two frames 2. The two scale frames 3 are fixedly provided with a second lifting seat 14, which is used to place the weight rod 4 during the check.

[0034] At least one lifting mechanism is fixedly arranged on each frame 2. In this embodiment, one lifting mechanism is arranged. The lifting mechanism includes a first fixing device 5 of a hollow structure. The first fixing device 5 is fixed on the lifting platform. The first fixing device 5 includes a square frame structure. A first lifting seat 13 is welded on the outer walls of the two non-adjacent sides of the square frame structure, that is, two first lifting seats 13 are symmetrically arranged about the square frame structure. The first lifting seat 13 is used to place the weight rod 4. The diameter of the groove arranged on the first lifting seat 13 is larger than the diameter of the weight rod 4. In this embodiment, the weight rod 4 is a cylinder. The first fixing device 5 can also be set to other structures according to actual needs, as long as the weight rod 4 can be placed.

[0035] A group of support arms are movably connected to both sides of the first fixing device 5 welded with the first lifting seat 13 through bolts 17, and a number of connecting parts 15 are movably connected between the two groups of support arms. In this embodiment, two connecting parts 15 are movably connected between every two groups of support arms, and the connecting parts 15 include a first connecting part and a second connecting part. Each group of support arms includes a first support arm 8 and a second support arm 9, and the first support arm 8 and the second support arm 9 are mirror-symmetrical structures with respect to the first lifting seat 13. The first support arms 8 are movably connected to each other through the first connecting part, and the second support arms 9 are movably connected to each other through the second connecting part. A first through hole is vertically penetrated on the side wall of the first connecting part, and a second through hole is vertically penetrated on the side wall of the second connecting part. The second through hole is coaxially arranged with the first through hole, and the central axis of the first through hole is perpendicular to the central axis of the first connecting part. In this embodiment, the connecting part 15 is a bearing.

[0036] The first support arm 8 includes an upper support arm 6 and a lower support arm 7, one end of the upper support arm 6 is movably connected to the first fixing device 5 by a bolt 17, one end of the lower support arm 7 is movably connected to the lifting platform by a rotating shaft 10, a third through hole is provided on the other end of the upper support arm 6, a fourth through hole is provided on the other end of the lower support arm 7, the third through hole is coaxially arranged with the fourth through hole, the first connecting member passes through the third through hole and the fourth through hole, and the upper support arm 6 and the lower support arm 7 can rotate around the connecting member 15. The second support arm 9 and its connection relationship are the same as the first support arm 8 and its connection relationship.

[0037] The weight rod 4 is parallel to the rotating component 1, and the rotating component 1 is perpendicular to the connecting component 15. The rotating component 1 passes through the first through hole, the first fixing device 5 and the second through hole, and then extends through the first through hole, the first fixing device 5 and the second through hole on the lifting mechanism on the next frame 2. The inner wall of the first through hole is provided with an internal thread that matches the external thread provided on the rotating component 1. In this embodiment, the inner wall of the second through hole is a smooth structure. The connecting component 15 can move radially along the rotating component 1, that is, the movement direction of the connecting component 15 is parallel to the central axis of the weight rod 4. The rotating component 1 in this embodiment is a screw rod. Those skilled in the art can also set the rotating component 1 to other structures according to actual needs, as long as it can achieve the coordination with the first through hole to control the movement of the connecting component 15, thereby driving the movement of the support arm, and then making the weight rod 4 placed on the first fixing device 5 move up and down. The second through hole and the rotating part 1 may also be clearance-matched or different external threads may be provided in sections on the rotating part, and the inner wall of the second through hole may be provided with internal threads that match the corresponding external threads on the rotating part 1, so that when the rotating part rotates, the movement directions of the first connecting part and the second connecting part are opposite. When the inner wall of the second through hole is a smooth structure or the second through hole and the rotating part 1 are clearance-matched, the gap reserved between the second through hole and the second connecting part should ensure that the second connecting part can move flexibly. In order to facilitate the rotation of the rotating part 1, a detachable rotating wheel or other auxiliary rotation device may be provided at one end of the rotating part 1. In this embodiment, an internal hexagonal thread 12 is provided at one end of the screw. When in use, the operator can clamp the internal hexagonal thread 12 with an adapted external hexagonal wrench adapter to achieve the rotation of the screw. After the operator has finished using it, the device for assisting the rotation of the rotating part 1 can be disassembled and kept by a dedicated person, thereby avoiding a series of problems caused by the random use of strangers.

[0038] A second fixing device 11 is provided on the rotating component 1 adjacent to the second connecting component. In this embodiment, the second fixing device 11 is a nut, through which the second connecting component is fixedly set on the screw rod, so that the second connecting component cannot move on the screw rod when the screw rod is rotated, that is, the position of the second connecting component on the rotating component 1 is fixed.

[0039] Since two first lifting seats 13 are welded on the first fixing device 5 in this embodiment, the operator can choose to use a single weight rod 4 or two weight rods 4 during the calibration process according to the needs. If two weight rods 4 are used, compared with the traditional single weight rod 4, it is more labor-saving and convenient to install the weight rod 4 under the same total weight, which can increase the calibration accuracy.

[0040] The support arm, bearing and rotating shaft 10 in the utility model form a labor-saving lever, which increases the movement stroke of the bearing in exchange for less power consumption per unit time, that is, compared with the existing hanging device, when lifting the same height, the original short-stroke high-torque operation mode is transformed into a long-stroke low-torque operation mode, making it easier and simpler for operators to operate, improving the efficiency of hanging and reducing the complexity of the hanging process. Based on this technical solution, technicians in this field can adjust the length of the force arm according to actual conditions, further making the operation easier and faster for operators.

[0041] When the weight-hanging calibration device of the utility model is in a non-calibration state, the weight rod 4 does not act on the scale frame 3. When the weight-hanging calibration device of the utility model is used for calibration, the rotating part 1 is rotated, the rotating part 1 rotates, and the first connecting part moves on the rotating part 1 to the side away from the first fixing device 5. Since one end of the upper supporting arm 6 of the first supporting arm 8 is movably connected to the first fixing device 5 through the bolt 17, one end of the lower supporting arm 7 of the first supporting arm 8 is movably connected to the lifting platform through the rotating shaft 10, and the other end of the upper supporting arm 6 of the first supporting arm 8 and the other end of the lower supporting arm 7 are movably connected to the first connecting part, the first supporting arm 8 rotates around the first connecting part when the first connecting part moves. Since the second supporting arm 9 and the first supporting arm 8 are both rotatably connected to the first fixing device 5 through the bolt 17, the second supporting arm 9 also rotates around the second connecting part when the first supporting arm 8 rotates around the first connecting part, thereby driving the second connecting part to move to the other side away from the first fixing device 5. In this embodiment, the second connecting part does not participate in the threaded movement during this movement. At this time, the first fixing device 5 moves downward, and the first fixing device 5 places the weight rod 4 on the second lifting seat 14 on the scale frame 3. After the verification is completed, the rotating component 1 is turned, the rotating component 1 rotates, the first connecting component moves toward the center position of the first fixing device 5 on the rotating component 1, and the second connecting component moves toward the center position of the first fixing device 5. At this time, the first fixing device 5 lifts the weight rod 4, and the weight rod 4 is away from the scale frame 3.
