Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering, and particularly relates to a hoisting and handling device suitable for multiple types of manhole covers. Background Art

[0002] With the acceleration of the urbanization process in China, the number of municipal pipeline construction projects is increasing day by day, and the number of various types of manhole covers has also increased accordingly. For example, manhole covers for rain and sewage pipelines, power manhole covers, communication manhole covers, etc. Traditional manhole cover handling mostly uses manual handling, which is not only time-consuming and laborious, but also there is a risk of the manhole cover slipping and injuring people during the handling process. At present, there are also tools in the market for handling manhole covers, but such tools often target a single type of manhole cover and are difficult to meet the handling requirements for different types of manhole covers.

[0003] Furthermore, before handling the manhole cover, it is necessary to first pry the manhole cover up from the inlet. This process is currently usually carried out by workers using crowbars, which not only has a high labor intensity, but also easily damages the manhole cover. Summary of the Utility Model

[0004] To solve or partially solve the problems existing in the related technologies, the present application provides a hoisting and handling device suitable for multiple types of manhole covers. This device can be applicable to the handling of different types of manhole covers, and through the cooperation of the lifting rope and the clamping block, the manhole cover can be directly lifted without the need to use a crowbar, thereby ensuring the integrity of the manhole cover.

[0005] The present application provides a hoisting and handling device suitable for multiple types of manhole covers, including a frame, moving wheels, a lifting chain, a fixed clamp, a lifting rope, and a clamping block. The bottom of the frame is rotatably installed with moving wheels, and a fixed clamp is installed at the end of the frame through a lifting chain. The manhole cover can be clamped and fixed by the fixed clamp. A lifting rope is also installed on the frame, and a clamping block is fixedly connected to the end of the lifting rope.

[0006] Optionally, in some embodiments, the clamping block has a long strip-shaped structure, and the cross-sectional dimension of the clamping block is smaller than the size of the through hole on the manhole cover, so that the clamping block can pass through the through hole on the manhole cover.

[0007] Optionally, in some embodiments, the fixed clamp includes a bottom plate, a threaded rod, a pressing plate, and a nut. The end of the lifting chain is fixedly connected to the bottom plate, and a threaded rod is fixedly arranged on the bottom plate. The threaded rod passes through the pressing plate and is threadedly connected to the nut.

[0008] Optionally, in some embodiments, wing pieces are provided on the side of the nut.

[0009] Optionally, in some embodiments, the frame includes a stress rod, a support rod, and a moving rod. Moving wheels are rotatably installed at the left and right ends of the moving rod, and a support rod is fixedly connected vertically at the middle position of the moving rod. The end of the support rod is perpendicularly connected to the stress rod, and the connection point is biased towards the end where the lifting chain is installed.

[0010] Optionally, in some embodiments, a stiffening rod is further provided between the stress rod and the support rod.

[0011] The technical solution provided by this application may include the following beneficial effects:

[0012] With the sling cooperating with the clamping block in this application, the manhole cover can be directly lifted without using a crowbar anymore, thus ensuring the integrity of the manhole cover; the manhole cover can be clamped and fixed by the fixing fixture for convenient handling, and the fixing fixture is connected by a lifting chain. When the size and type of the manhole cover change, the flexibility of the lifting chain can adapt to the change, so as to meet the needs of handling different types of manhole covers.

[0024] See Figure 1 , a lifting and handling device applicable to multiple types of manhole covers, including a frame 1, moving wheels 2, a lifting chain 4, a fixed fixture 5, a lifting rope 6, and a clamping block 61. The frame 1 includes a stress rod 11, a support rod 12, and a moving rod 13. Moving wheels 2 are rotatably installed at the left and right ends of the moving rod 13, and a support rod 12 is vertically welded and fixed at the middle position of the moving rod 13. The end of the support rod 12 is perpendicularly connected to the stress rod 11. A lifting chain 4 is installed at one end of the stress rod 11, and the connection between the support rod 12 and the stress rod 11 is biased towards the end where the lifting chain 4 is installed, so that the stress rod 11 forms a lever structure with the support rod 12 as the fulcrum, facilitating the staff to lift and handle the manhole cover 7. Further, in order to improve the stability of the stress rod 11, a stiffening rod 14 is also provided between the stress rod 11 and the support rod 12.

[0025] At the end of the stress rod 11, a mounting seat 3 is fixedly connected. Four suspension chains 4 are evenly and fixedly connected circumferentially to the mounting seat 3. The ends of the suspension chains 4 are fixedly connected with fixed clamps 5. The manhole cover 7 can be clamped and fixed by four groups of fixed clamps 5, thus ensuring the safety during the process of carrying the manhole cover 7. Further, a lifting rope 6 is also fixedly installed on the mounting seat 3, and a clamping block 61 is fixedly connected to the end of the lifting rope 6.

[0026] Generally, through holes 71 are provided on the manhole cover 7. The through holes 71 can not only allow the air in the well to circulate, avoid oxygen deficiency and carbon dioxide accumulation, ensure the fresh air inside the well, but also help to maintain the air pressure balance inside and outside the well. Especially when a vehicle passes by quickly, it can reduce the risk of the manhole cover moving or bouncing due to the impact of air flow.

[0027] See Figure 2 , the clamping block 61 has a strip-shaped structure, and the cross-sectional dimension of the clamping block 61 is smaller than the dimension of the through hole 71 on the manhole cover 7, so that the clamping block 61 can pass through the through hole 71 on the manhole cover 7. During use, the clamping block 61 is vertically passed through the through hole 71. After the clamping block 61 completely passes through the through hole 71, the lifting rope 6 is pulled back, so that the clamping block 61 clamps the inner wall of the manhole cover 7. The manhole cover 7 can be lifted from the wellhead by pulling the lifting rope 6. After the lifted manhole cover 7 is fixed by the fixed clamp 5, the rack 1 can be pushed for transportation.

[0028] See Figure 3 , the fixed clamp 5 includes a bottom plate 51, a threaded rod 52, a pressing plate 53, and a nut 54. The end of the suspension chain 4 is fixedly connected to the bottom plate 51. The threaded rod 52 is fixedly arranged on the bottom plate 51. The threaded rod 52 passes through the pressing plate 53 and is threadedly connected to the nut 54. During use, the edge of the manhole cover 7 is placed on the bottom plate 51. By rotating the nut 54, the pressing plate 53 is driven to move downward to press the manhole cover 7, so as to fix the manhole cover 7. Further, in order to facilitate manually rotating the nut 54, two wing pieces 55 are symmetrically arranged on the side surface of the nut 54.

[0029] Specific working process:

[0030] Push the device to the side of the manhole cover 7 to be carried, pass the clamping block 61 through the through hole 71 on the manhole cover 7, so that the clamping block 61 clamps the inner wall of the manhole cover 7. Press down the labor-saving end of the stress rod 11 to lift the manhole cover 7. Use four fixed clamps 5 to evenly clamp and fix the edge of the manhole cover 7. After the fixation is completed, push the rack 1 to move to the designated location to complete the transportation.

[0031] Finally, it should also be noted that in this text, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising" or any other variant are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0032] The embodiments of the present application have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
