Description

Technical Field

[0001] This utility model relates to the field of cable trench cover extraction technology, specifically a cable trench cover extraction tool. Background Technology

[0002] Cable trench covers are commonly used to cover and protect cables and pipe trenches, preventing pedestrians or vehicles from falling in. They are usually prefabricated using materials such as reinforced concrete, and have high load-bearing and compressive strength, but are also quite heavy. Because cable trenches or pipe trenches require frequent inspection and monitoring after construction, it is necessary to open the covers. Furthermore, the weight of the covers makes them inconvenient to move and lift during inspections.

[0003] To facilitate the removal of cable trench covers during inspections, existing technologies typically require multiple people to work together to lift the covers. However, this manual handling method is not only inefficient and labor-intensive, but also poses safety risks such as covers falling and injuring workers during the removal process, and it takes a considerable amount of time. To address these issues, this invention provides a cable trench cover removal tool. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable trench cover extraction tool, which solves the problems of low work efficiency, high manpower requirements, safety issues such as the cover falling and injuring workers during the extraction process, and long extraction time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable trench cover extraction tool, comprising a channel steel, with a wheel installed at the bottom of the middle section of the channel steel, and a sliding rod extraction assembly fixedly connected to one end of the channel steel. The sliding rod extraction assembly comprises a horizontal bar body, a hook vertical bar, a hook horizontal bar, and a bolt. The hook vertical bar is slidably connected within the horizontal bar body, and the bolt is rotatably connected within the hook vertical bar. The hook horizontal bar is rotatably connected to the bottom of the hook vertical bar via the bolt.

[0006] Preferably, a handle is fixedly connected to the end of the channel steel away from the slide bar extraction assembly.

[0007] Preferably, a bracket is fixedly connected to the bottom of the middle section of the channel steel, and the wheel is rotatably connected to both ends of the bracket.

[0008] Preferably, horizontal bars are fixedly connected to the inner walls on both sides of the main body of the horizontal bar, and vertical bars are fixedly connected to the inner walls of the horizontal bars on both sides.

[0009] Preferably, the slide bar extraction assembly further includes a collar and a chain;

[0010] The collar is slidably connected to the vertical rod, one end of the chain is fixedly connected to the collar, and the other end of the chain is fixedly connected to the hook vertical rod.

[0011] This utility model discloses a cable trench cover extraction tool, which has the following beneficial effects: The device uses the double wheels commonly used in ordinary wheelbarrows as moving wheels and lever fulcrums, uses a long channel steel as the lever arm, and has a sliding rod at the end for adjusting the distance. The appropriate position is selected according to the position of the pre-drilled hole in the cover plate. A cover plate extraction hook is provided on the sliding rod. The cover plate extraction hook is passed through the pre-drilled hole in the cover plate, and the cover plate is lifted from one end of the handle to complete the extraction of the cable trench cover plate. This reduces the waste of manpower, reduces safety hazards during construction and inspection, and improves work efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This application provides a cable trench cover extraction tool, which solves the problems of low work efficiency, large manpower requirements, safety issues such as the cover falling and injuring workers during the extraction process, and long extraction time by providing a cable trench cover extraction tool.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a tool for extracting cable trench covers.

[0023] According to the appendix Figure 1-5 As shown, the device includes a channel steel 2, with a wheel 3 installed at the bottom of the middle section of the channel steel 2. A sliding rod extraction assembly 5 is fixedly connected to one end of the channel steel 2. The sliding rod extraction assembly 5 includes a horizontal bar body 58, a hook vertical bar 54, a hook horizontal bar 55, and a bolt 56. The hook vertical bar 54 is slidably connected inside the horizontal bar body 58, and the bolt 56 is rotatably connected inside the hook vertical bar 54. The hook horizontal bar 55 is rotatably connected to the bottom of the hook vertical bar 54 via the bolt 56. This device uses the lever principle to extract heavy cable trench covers. By adjusting the sliding rod extraction assembly 5 to the position above the cover's slot, and using the rotatable extraction hook formed by the hook vertical bar 54, hook horizontal bar 55, and bolt 56, the hook passes through the slot of the cable trench cover and is pressed down at the other end of the channel steel 2, using the lever principle to extract the cover, thus improving the safety of the workers during construction.

[0024] A handle 1 is fixedly connected to one end of the channel steel 2 away from the slide bar extraction component 5. A bracket 4 is fixedly connected to the bottom of the middle section of the channel steel 2. Wheels 3 are rotatably connected to both ends of the bracket 4. The device is equipped with a handle 1 as a lever arm support, which is convenient for disassembly and assembly, and also convenient for workers to exert force to press down and lift the cover plate. At the same time, movable wheels 3 are set at the middle shaft, which makes the movement and transportation of the device more convenient and improves the versatility of the device.

[0025] A crossbar 51 is fixedly connected to the inner walls of both sides of the crossbar body 58, and a vertical bar 57 is fixedly connected inside the crossbars 51 on both sides. The sliding bar extraction assembly 5 also includes a collar 52 and a chain 53. The collar 52 is slidably connected to the vertical bar 57, one end of the chain 53 is fixedly connected to the collar 52, and the other end of the chain 53 is fixedly connected to the hook vertical bar 54. When in use, the collar 52 is used to slide and position the cable trench cover at the hole groove. At the same time, the rotatable nature of the chain 53 makes it easier to fix the extraction hook composed of the hook vertical bar 54, the hook crossbar 55, and the bolt 56. This makes it convenient to use cable trench covers of various sizes in various environments, further enhancing its versatility.

[0026] In summary, compared with existing technologies, it has the following beneficial effects:

[0027] A tool for extracting cable trench covers utilizes the lever principle. The device uses a wheel 3, commonly found on ordinary wheelbarrows, as the moving wheel and lever fulcrum. A long channel steel bar 2 serves as the lever arm, with a sliding rod extraction assembly 5 at the end for adjusting the distance. The appropriate position is selected based on the location of the pre-drilled hole in the cover. The sliding rod extraction assembly 5 is equipped with a cover extraction hook, a vertical hook 54, and a horizontal hook 55. The horizontal hook 55 is passed through the pre-drilled hole in the cover, and the cover is lifted from one end of the handle 1, thus completing the extraction of the cable trench cover. This reduces manpower waste, minimizes safety hazards during construction and inspection, and improves work efficiency.
