[0002] Truck scales have been in operation for many years, enduring frequent impacts from weighing vehicles. As a result, their civil engineering components have gradually become loose and displaced, leading to frequent equipment malfunctions. Consequently, the number of civil engineering upgrade projects for truck scales has been increasing in recent years. Before lifting operations on the truck scale equipment, maintenance personnel need to open the cover plates in advance; however, these cover plates are deformed due to long-term impacts.

[0003] In practice, due to the lack of suitable specialized tools, maintenance personnel often have to work in pairs, removing the cover plates by hand with their fingers. When reinstalling them after the work is completed, the same applies – the cover plates must be put back in by hand. Furthermore, the small spacing between the holes in the cover plates, their low installation height, and their heavy weight make it extremely easy for maintenance personnel to suffer hand injuries, foot injuries, and back injuries during handling, disassembly, installation, and adjustment of the cover plates. Additionally, the workload for these workers is very high. Utility Model Content

[0021] 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.

[0022] The purpose of this utility model is to provide a tool for disassembling truck scale covers to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the efficiency of truck scale maintenance, effectively reduces labor intensity, and effectively eliminates safety risks.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a tool for disassembling a truck scale cover, such as... Figure 1 As shown, it includes: a support rod 1, a handle 2, and a locking head 3. The support rod 1 has a first end and a second end that are arranged opposite to each other. The handle 2 is fixedly connected to the first end of the support rod 1. The locking head 3 is fixedly connected to the second end of the support rod 1. The length direction of the handle 2 is parallel to the length direction of the locking head 3. Both the handle 2 and the locking head 3 are perpendicular to the support rod 1, so that the handle 2, the locking head 3, and the support rod 1 form an I-shaped structure. The I-shaped structure design is simple and stable. The perpendicular and parallel arrangement of the handle 2, the locking head 3, and the support rod 1 provides the operator with a comfortable grip, facilitates the application of force for disassembly operations, and can better transmit force to the locking head 3 to act on the cover plate, which helps to achieve efficient and stable cover plate disassembly work.

[0025] In a preferred embodiment, the length of the clamping head 3 is greater than the diameter of the hole in the cover plate to be removed, allowing the clamping head 3 to be inserted obliquely into the underside of the cover plate to be removed through the hole, and to form a load-bearing contact with the inner surface of the cover plate after being aligned. The fact that the clamping head 3 is longer than the diameter of the hole in the cover plate and can be inserted obliquely and formed a load-bearing contact with the inner surface of the cover plate after being aligned allows the tool to be firmly connected to the cover plate to be removed, providing a reliable support point during the disassembly process, enhancing the connection stability between the tool and the cover plate, preventing the clamping head 3 from detaching from the cover plate during disassembly, and ensuring smooth disassembly of the cover plate.

[0026] In a preferred embodiment, the length (L) of the clamping head 3 and the diameter (D) of the cover plate hole satisfy the relationship: L≥1.4D. By clarifying the quantitative relationship between the length of the clamping head 3 and the diameter of the cover plate hole, it is ensured that the clamping head 3 can be smoothly inserted into the hole at an angle and stably supported under the cover plate after being aligned. This can effectively adapt to the disassembly requirements of cover plates with various hole sizes, improve the versatility and applicability of the tool to cover plates of different specifications, and provide a precise design basis for actual operation.

[0027] In a preferred embodiment, the handle 2, support rod 1, and clamp 3 are all made of metal tubing. Using metal tubing to make the handle 2, support rod 1, and clamp 3 ensures that the tool has sufficient strength and durability, can withstand large external forces during disassembly without being easily damaged, extends the tool's service life, and reduces usage costs. At the same time, the metal tubing material is relatively uniform, making it easy to process and manufacture.

[0028] In a preferred embodiment, the metal tubing is a 25mm diameter steel pipe. By explicitly selecting a 25mm diameter steel pipe, the dimensions and specifications of each component of the tool can be determined. This type of steel pipe is relatively common in the market and easy to obtain, which reduces the manufacturing cost of the tool. At the same time, while ensuring the strength and performance of the tool, the appropriate pipe diameter also makes it convenient for the operator to hold and operate the tool.

[0029] In a preferred embodiment, the handle 2, support rod 1, and clamp 3 are fixedly connected by welding. The welding connection makes the connection between the handle 2, support rod 1, and clamp 3 more robust and reliable, ensuring that the components will not loosen or separate during frequent disassembly operations, thus guaranteeing the stability and reliability of the overall tool structure and ensuring the smooth progress of disassembly work.

[0030] In a preferred embodiment, the support rod 1 includes a first pipe 11, a second pipe 12, and a first length adjustable structure. The first pipe 11 and the second pipe 12 are connected by the first length adjustable structure. By setting the first length adjustable structure to connect the first pipe 11 and the second pipe 12, the length of the support rod 1 can be flexibly adjusted according to the specific installation position of different truck scale covers, actual usage scenarios, and other factors, thereby enhancing the tool's adaptability to different working conditions and further improving the tool's versatility and applicability.

[0031] In a preferred embodiment, the first length-adjustable structure includes a threaded connection, a sleeve connection, or a pin-positioning connection, providing a variety of optional length-adjustable structures. The threaded connection is characterized by a tight and stable connection and relatively precise operation during adjustment; the sleeve connection is simple and facilitates quick length adjustment; the pin-positioning connection can quickly position and fix the length at different locations, providing operators with diversity to choose the appropriate connection method according to actual needs, and better meeting various complex usage requirements.

[0032] In a preferred embodiment, the tool further includes a first extension tube 4, a second extension tube 5, a second length adjustable structure, and a third length adjustable structure. The first extension tube 4 is connected to one end of the clamp 3 via the second length adjustable structure, and the second extension tube 5 is connected to the other end of the clamp 3 via the third length adjustable structure. The addition of the first extension tube 4 and the second extension tube 5, each connected to both ends of the clamp 3 via adjustable structures, greatly enhances the tool's flexibility and adaptability under different working conditions. In some special scenarios involving the installation of truck scale covers, such as when the cover is deep, the space around the hole is limited, or additional length is required for better application to the cover, the extension tubes can be stretched or shortened by adjusting the second and third length adjustable structures. This allows the tool to reach and effectively apply to the cover, expanding its application range and improving its applicability and operability.

[0033] In a preferred embodiment, the second length-adjustable structure includes a threaded connection, a sleeve connection, or a pin-positioning connection, and the third length-adjustable structure also includes a threaded connection, a sleeve connection, or a pin-positioning connection. This provides multiple length-adjustable connection structures, and both the second and third length-adjustable structures incorporate threaded connections, sleeve connections, or pin-positioning connections, offering users a wide range of operational options in different work scenarios. Threaded connections ensure connection stability and adjustment accuracy, suitable for situations requiring precise length extension; sleeve connections are simple and quick to operate, enabling rapid length adjustment and improving work efficiency; pin-positioning connections, while allowing length adjustment, can be conveniently and quickly fixed in the desired position to meet various complex and changing usage needs, further enhancing the tool's practicality and flexibility.

[0034] Instructions for using the above-mentioned tools for removing truck scale covers

[0035] When using this truck scale cover removal tool, the operator first adjusts the adjustable parts of the tool according to the actual installation location of the truck scale cover to be removed, the hole size, and the surrounding space. If the cover to be removed is located deep or the surrounding space is limited, the lengths of the first extension tube 4 and the second extension tube 5 can be stretched or shortened by adjusting the second and third length adjustable structures, so that the clamp 3 can smoothly reach the position of the cover to be removed. At the same time, if the initial length of the support rod 1 is not suitable for the current operation, the length of the support rod 1 can be adjusted through the first length adjustable structure to ensure that the operator can operate in a comfortable posture.

[0036] After adjusting the lengths of all parts of the tool, the operator holds the handle 2 with both hands, aligns the clamping head 3 with the hole in the cover plate to be removed, and inserts the clamping head 3 at an angle under the hole in the cover plate. During insertion, care should be taken to control the force and angle to ensure that the clamping head 3 can enter smoothly without excessive collision with the edge of the cover plate. After the clamping head 3 is inserted at an angle under the cover plate, slowly straighten the clamping head 3 so that it forms a stable bearing contact with the inner surface of the cover plate to be removed. At this point, the design advantage of the clamping head 3 being longer than the diameter of the hole in the cover plate becomes apparent, ensuring that the clamping head 3 is firmly supported under the cover plate after being straightened, providing a reliable support point for subsequent disassembly work.

[0037] After confirming that the clamp 3 and the cover plate have formed a good bearing contact, the operator applies an upward pulling force through the handle 2. The direction and magnitude of the force can be adjusted as needed, utilizing the lever principle to remove the cover plate from the truck scale. During disassembly, due to the tool's unique I-beam structure design and the stable connection between components, the force can be effectively transmitted from the handle 2 to the clamp 3, acting on the cover plate, making the disassembly work easier and more efficient.

[0038] After the cover plate is successfully removed, the operator removes the tool from it. To install the cover plate, the reverse procedure is followed. First, insert the clamp 3 at an angle under the hole in the cover plate and align it to form a load-bearing contact. Then, align the cover plate with the installation position on the truck scale and slowly lower it. As the cover plate approaches the installation position, its position can be fine-tuned using the tool to ensure accurate installation. Finally, remove the tool from the cover plate to complete the installation or removal of the cover plate. Throughout its use, this tool, with its reasonable design and flexible adjustability, can adapt to truck scale covers of different specifications and installation scenarios, significantly reducing the labor intensity of maintenance personnel, improving maintenance efficiency, and effectively eliminating safety risks.
