Description

Technical Field

[0001] This application relates to the technical field of hook scale verification devices, and in particular, to a jump detection structure for a hook scale verification device. Background Art

[0002] An electronic hook scale is a new type of weighing device that integrates a weighing body, a sensor, and a power supply. It can be directly hung on the crane hook, enabling loading, unloading, and weighing to be carried out simultaneously, with simple and effective operation. It is widely used in heavy machinery, logistics warehousing, port terminal loading, unloading, and weighing. It is an indispensable weight measurement equipment for realizing modern enterprise management operations. Most of its applications involve trade settlement and fall within the scope of legal verification. However, due to its simple accessory structure, it cannot meet the needs of modern fast and efficient detection. For example, electronic hook scales used for loading and unloading bulk goods at ports come in models such as 1 - 5 tons and 1 - 10 tons, which require annual verification, and this is mandatory.

[0003] Currently, devices for hook scale verification at home and abroad can be classified into the following categories according to their structures and principles:

[0004] 1. Static weight type: Uses the gravity of weights as the standard load. Through an appropriate mechanism, the load is directly and automatically applied to the hook of the hook scale to be verified in a predetermined order. The weights are both the force source and give the magnitude of the force value. It is characterized by high accuracy and a large range of measurement, but the manufacturing cost increases significantly with the increase in the range, and it is mainly applied to the detection of hook scales with small ranges.

[0005] 2. Superposition type: Uses a standard force measuring instrument (or a group of them) with higher accuracy than the hook scale to be verified as the standard, which is connected in series with the hook scale to be verified, and is a hook scale verification device that applies the load in a hydraulic or mechanical manner. With the improvement of the technical performance of force sensors and force source devices, the metrological performance of superposition type hook scale verification devices has also been greatly improved. Due to its low cost and high work efficiency, it has been widely recognized in recent years. However, due to the limited range of the standard force measuring instrument, there are still certain limitations in its use, and it is mainly applied to the detection of hook scales with large ranges.

[0006] Currently, commonly used hook scale verification devices mainly include a main bracket, a large weight assembly, and corresponding connection components. During the verification process, the hook scale is suspended and connected through the main bracket, and the large weight assembly is used for loading tests to detect the accuracy of the hook scale under different loads. However, such verification devices can usually only perform static load tests during use, and it is difficult to comprehensively evaluate the jump error of the hook scale during use, especially the sensitivity and accuracy problems during the switching of different loads. Existing verification devices lack a mechanism that can quickly detect minute jumps at the moment of loading and unloading. Summary of the Utility Model

[0036] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 drawings.

[0037] This embodiment discloses a jump detection structure for a hook scale verification device.

[0038] Referring to Figure 1 , a hook scale verification device includes a main bracket 1, which is assembled by a top plate, a support plate, and a bottom plate arranged in sequence from top to bottom through support rods. A large weight assembly 4 is arranged on the bottom plate. A through hole for the up and down movement of the large weight assembly 4 is opened in the middle of the support plate. A connection head 2 for connecting the hook scale is arranged below the top plate. The connection head 2 is connected to the top plate through a lifting mechanism 3. A jump detection assembly 6 is arranged above the support plate. An electric control box 7 for controlling the verification device is arranged on one side of the support plate.

[0039] Referring to Figure 2 , Figure 3 and Figure 4, the jump detection component 6 includes a string of miniature weights 65 symmetrically arranged on both sides of the hanging ring 8. The string of miniature weights 65 is connected to the hanging ring 8 through the mounting rod 9. Two sets of lifting and sliding table components 61 are symmetrically arranged on both sides of the support plate. The lifting and sliding table component 61 includes a lifting slide rail 611 fixedly arranged on one side of the middle of the main bracket 1 in the vertical direction. A sliding seat 612 is slidably arranged on the lifting slide rail 611. The lifting arm 62 is fixedly connected to the sliding seat 612. A driving motor 613 for driving the sliding seat 612 to move up and down reciprocally is arranged at the upper end of the lifting slide rail 611. A lifting arm 62 extending above the string of miniature weights 65 is arranged on the lifting and sliding table component 61. The end of the lifting arm 62 is connected to a weight support 64. The weight support 64 includes two support plates 68 symmetrically arranged up and down. The edges of the two support plates 68 are fixedly connected by three connecting rods 642. The string of miniature weights 65 is arranged between the two support plates 68. The string of miniature weights 65 is composed of a number of miniature weights 652 arranged from top to bottom. The mass of the number of miniature weights 652 gradually increases from top to bottom. A connecting groove 653 is opened in the middle of the bottom surface of the miniature weight 652. Adjacent two miniature weights 652 are movably connected by a connecting rod 651 movably arranged inside the connecting groove 653. The upper end of the connecting rod 651 and the connecting groove 653 are both arranged in an inverted conical shape. This connection method makes the movement of the string of miniature weights 65 smoother under different loads. The inverted conical design of the connecting rod 651 and the connecting groove 653 makes the connection more stable, avoiding connection failure caused by rapid movement during the loading and unloading processes. The miniature weight 652 is made of a high-precision metal material, such as stainless steel or aluminum, to ensure that its weight is not affected by the environment during long-term use. The mounting hole can be designed as a through hole or a threaded hole with a small size, which is convenient for installation and disassembly.

[0040] Referring to Figure 2 and Figure 5 , a mounting hole matching the upper end of the connecting rod 9 is arranged on the mounting rod 9. The string of miniature weights is detachably connected to the mounting rod 9 through the connecting rod 9. A hanging rack 66 is arranged on one side of the lifting and sliding table component 61. A number of strings of miniature weights 65 with different masses are arranged on the hanging rack 66. This detachable connection method not only facilitates the installation and disassembly of the string of miniature weights 65, but also enables the entire verification device to replace the string of miniature weights 65 with different masses according to needs when different usage scenarios or the types of hook scales to be tested change, improving the detection efficiency and convenience.

[0041] The implementation principle of a jump detection structure for a hook scale verification device in this embodiment is:

[0042] In summary, by providing the micro-weight string and the lifting arm, the present application can quickly detect minute jumps at the moment of loading and unloading of the hook scale, improving the detection accuracy of the verification device; the micro-weight string is detachably connected to the mounting rod through the connecting rod, facilitating the adjustment of the mass combination of the micro-weight string, and improving the flexibility and application range of the verification device; the setting of the lifting slide assembly enables the micro-weight string to be detected at different positions, enhancing the functionality and reliability of the verification device. Therefore, the present application effectively overcomes various drawbacks in the prior art and has high industrial utilization value.
