Description

Technical Field

[0001] This utility model relates to the field of manhole cover installation equipment, and in particular to a manhole cover disassembly, assembly and transfer device for inspection wells. Background Technology

[0002] Inspection wells are typically located at intersections, bends, changes in pipe diameter or slope, drop structures, and at regular intervals along straight pipe sections. They are drainage auxiliary structures designed to facilitate periodic inspection, cleaning, and unblocking of the pipes. Because inspection well covers need to be opened periodically for inspection, and due to the tight fit between the cover and the well opening, as well as their considerable weight, manual disassembly and assembly without tools is difficult. Furthermore, when the cover is removed and moved short distances, additional transport equipment is required, making the process inconvenient. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a manhole cover disassembly and transportation device, which facilitates the disassembly and assembly of manhole covers and facilitates short-distance transportation of manhole covers, thereby improving operational convenience.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a manhole cover disassembly and transfer device, including a rotating shaft, with traveling wheels installed at both ends of the rotating shaft, including a support frame, with the lower end of the support frame rotatably installed on the rotating shaft, an operating lever provided at the upper end of the support frame, a hanging ring provided at the front end of the operating lever, two sets of hanging chains provided on the hanging ring, a hook provided at the lower end of the hanging chains, and a mounting ring rotatably installed on the rotating shaft at one end of a limiting rod, with the other end of the limiting rod detachably connected to the operating lever.

[0005] In a preferred embodiment, the operating lever is provided with a sliding groove for the limiting rod to pass through, and both the operating lever and the limiting rod are provided with through holes for the pin to pass through. After the end of the limiting rod is inserted into the sliding groove, the pin is simultaneously inserted into the through holes on the operating lever and the limiting rod to connect the operating lever and the limiting rod.

[0006] In a preferred embodiment, the support frame includes a support sleeve, which is rotatably mounted on a rotating shaft and connected to an operating lever via a support rod.

[0007] In a preferred embodiment, the hook has an inverted "T" shaped structure.

[0008] In a preferred embodiment, the operating lever is provided with a handle at its tail.

[0009] The manhole cover disassembly and transfer device provided by this utility model has the following beneficial effects:

[0010] 1. By using the lever principle, the manhole cover can be lifted, which facilitates the removal of the manhole cover from the manhole opening and enables the disassembly and assembly of the manhole cover, solving the problem that existing manhole covers are not easy to lift and remove from the manhole opening.

[0011] 2. After the manhole cover is lifted off the manhole or ground by the device, the connection between the limiting rod and the operating lever can limit the further rotation of the operating lever. The operator does not need to keep pressing down on the operating lever. On the one hand, it reduces the difficulty of operation for the operator, and on the other hand, it prevents the manhole cover from being lifted too low due to the rotation of the operating lever and colliding with the ground, which would affect the transfer.

[0017] like Figures 1-3 As shown, a manhole cover disassembly and transfer device includes a rotating shaft 1, with wheels 2 mounted at both ends of the rotating shaft 1, and a support frame 3. The lower end of the support frame 3 is rotatably mounted on the rotating shaft 1. An operating lever 4 is provided at the upper end of the support frame 3, and the operating lever 4 is perpendicular to the rotating shaft 1. A hanging ring 5 is provided at the front end of the operating lever 4, and two sets of lifting chains 6 are provided on the hanging ring 5. A hook 7 is provided at the lower end of the lifting chains 6. In this embodiment, the hook 7 has an inverted "T" shaped structure, such as... Figure 2 As shown, the hook 7 with the inverted "T" shape extends into the bottom of the manhole cover through the opening on the manhole cover. Then, the direction of the hook 7 is adjusted so that it is horizontally perpendicular to the opening of the manhole cover, thus completing the installation of the manhole cover.

[0018] The operating lever 4 has a handle 10 at its tail. The distance from the position of the operating lever 4 mounting support 3 to the handle 10 is twice the distance from the position of the operating lever 4 mounting support 3 to the front end. By utilizing the lever principle, it is convenient to apply force to the operating lever 4.

[0019] One end of the limiting rod 8 is provided with a mounting ring 801 that is rotatably mounted on the rotating shaft 1. Specifically, the mounting ring 801 is rotatably mounted on the rotating shaft 1 via a bearing. The other end of the limiting rod 8 is detachably connected to the operating lever 4. The limiting rod 8 can be connected to the operating lever 4 by bolts.

[0020] Alternatively, in this embodiment, the operating lever 4 is provided with a sliding groove 401 through which the limiting rod 8 passes. The sliding groove 401 is a strip-shaped hole. Both the operating lever 4 and the limiting rod 8 are provided with through holes through which the pin 9 passes. After the end of the limiting rod 8 is inserted into the sliding groove 401, the pin 9 is simultaneously inserted into the through holes on the operating lever 4 and the limiting rod 8 to connect the operating lever 4 and the limiting rod 8, thereby realizing a detachable connection between the operating lever 4 and the limiting rod 8.

[0021] When the limit rod 8 is connected to the operating lever 4, it can restrict the free rotation of the operating lever 4, keeping it at a fixed angle, which facilitates the transfer of the manhole cover.

[0022] In this embodiment, as Figure 3 As shown, the support frame 3 includes two sets of support sleeves 301 and support rods 302. The support sleeves 301 are rotatably mounted on the rotating shaft 1 through bearings. The support sleeves 301 are connected to the operating lever 4 through the support rods 302. The two sets of support rods 302 are inclined to form a stable triangular support, which improves the support stability of the operating lever 4.

[0023] The working principle of this device is as follows:

[0024] Lift the tail end of the operating lever 4 upwards. The operating lever 4 rotates around the support frame 3, causing the front end of the support frame 3 to lower. Hook 7 is then placed inside the opening of the manhole cover. Press down the tail end of the operating lever 4, causing it to rotate in the opposite direction around the support frame 3 until the manhole cover is lifted upwards and removed from the manhole or ground. Then rotate the limiting rod 8 so that the through hole through which the pin 9 passes on the limiting rod 8 aligns with the through hole through which the pin 9 passes on the operating lever 4. Insert the pin 9 to complete the connection between the operating lever 4 and the limiting rod 8. When rod 8 is connected, the limiting rod 8 limits the operating lever 4 to prevent the height of the lifted manhole cover from changing due to random rotation, which would prevent smooth transfer. Then, the operating lever 4 is pulled to move the entire device. After the manhole cover is transferred to the target position, the connection between the limiting rod 8 and the operating lever 4 is released. The operating lever 4 rotates with the support frame 3 as the fulcrum. The front end of the support frame 3 is lowered. After the manhole cover is placed on the ground or at the manhole opening, the hook 7 is disengaged from the opening of the manhole cover, completing the transfer and disassembly / removal of the manhole cover.
