Description

Technical Field

[0001] This utility model relates to the field of pipeline installation equipment technology, and in particular to a drainage pipeline rotation correction device. Background Technology

[0002] In municipal engineering construction, the installation of drainage pipes is a key link to ensure the normal operation of the urban drainage system. Drainage pipes are usually heavy and large in size, and their hoisting and installation process requires equipment such as hoists or cranes.

[0003] In current drainage pipe hoisting operations, the connection between the pipe and the hook is often flexible (such as simply binding with wire ropes). Since the crane's hoisting motion typically rotates around a fixed axis, when the pipe is hoisted above the pipe trench, factors such as the slack of the flexible connection and inertia during hoisting cause a deviation between the pipe's axial direction and the trench's orientation, preventing direct lowering. This necessitates manual adjustment of the pipe's angle by construction workers, which is not only inefficient and prolongs the laying time for a single pipe, but also poses significant safety risks to operators, especially for heavy concrete pipes. Utility Model Content

[0040] Below, in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be further described in detail below, along with specific implementation methods. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0041] A drainage pipe 9 rotation straightening device includes a lifting hook 1, a hook connecting structure 2, a bearing plate 3, a rotating platform structure 4, a suspension connecting structure 5, a control structure 6, a horizontal limiting structure 7, and an angle adjustment structure 8. The lifting hook connecting structure 2 connects to the lifting hook 1, improving structural stability during lifting. The bearing plate 3 supports the rotating platform structure 4 and the suspension connecting structure 5. The suspension connecting structure 5 connects and fixes the pipe to the rotating platform structure 4. The rotation of the rotating platform structure 4 enables the rotation of the drainage pipe 9. The control structure 6 allows for remote control of the rotating platform, enabling operators to adjust the pipe angle safely using wireless transmission technology, thus improving construction safety. The horizontal limiting structure 7 provides lateral limiting for the hook components, further improving the overall lifting stability of the device. The angle adjustment structure 8 allows for horizontal adjustment of the rotating platform structure 4.

[0042] For details, please refer to the appendix. Figure 1 and attached Figure 2 The lifting hook 1 is a commonly used hook for existing cranes, which includes a pulley block 11 and a hook body 12 connected to the lower end of the pulley block 11. The pulley block 11 uses at least two pulley blocks 11. The hook body 12 includes a hook shank 121 connected to the pulley block 11 and a hook portion 122 located at the lower end of the hook shank 121. The inner side of the hook portion 122 is curved into an arc shape, which is used to achieve a fitting function with the hook connection structure 2 through the arc-shaped inner side of the hook portion 122, reducing relative displacement during the lifting process and improving connection stability; at the same time, it is used to achieve the basic bearing function for the lifting operation of the drainage pipe 9 through the overall structure of the hook body 12.

[0043] Please refer to the attached document. Figure 2 The hook connection structure 2 includes two parallel first clamping plates 21 and second clamping plates 22, and a limiting component 23. In this embodiment, both the first clamping plates 21 and second clamping plates 22 are rectangular steel plates. The first clamping plates 21 and second clamping plates 22 are respectively vertically arranged on both sides of the two main facades of the hook body 12. The inner side of the first clamping plate 21 is provided with a limiting column 211 that penetrates the bent part of the hook and the second clamping plate 22. The limiting component 23 is configured to be fixedly arranged at the outer end of the limiting column 211 and abut against the outer side of the second clamping plate 22 to clamp the hook between the first clamping plate 21 and the second clamping plate 22. This is to achieve the lateral fixing function of the hook body 12 through the clamping action of the first clamping plate 21 and the second clamping plate 22, that is, the axial limiting of the limiting column 211, and to improve the uniformity of force distribution by means of the large area of ​​the main facade.

[0044] Please refer to the attached document. Figure 2 and attached Figure 3 The limiting column 211 includes a column component 2111 and several sets of fixing bolts 2112. The outer surface of the column component 2111 is adapted to fit the inner surface of the curved portion of the hook component. Simultaneously, the limiting column 211 passes through the curved portion of the hook component, thereby limiting the column radially and further improving the connection stability between the hook connection structure 2 and the hook component. At one end of the column component 2111 near the first clamping plate 21, multiple fixing holes 2113 are provided for threaded engagement with the fixing bolts 2112. The fixing bolts 2112 pass through the first clamping plate 21 and extend into the fixing holes 2113 to fix the column component 2111 to the first clamping plate 21. This allows for flexible assembly of the column component 2111 and the first clamping plate 21 through a detachable connection, facilitating replacement of hook components of different specifications. The adaptable column component 2111 improves the versatility of the device; the second vertical plate is provided with a limiting through hole 221 for the limiting column 211 to pass through, and the limiting component 23 is used to prevent the limiting column 211 from coming off the second vertical plate. In this embodiment, a pin can be used. For low-weight load scenarios of hoisting plastic drainage pipes 9, although the pin does not form a strong clamping force on the first clamping plate 21 and the second clamping plate 22, it is sufficient to achieve the anti-detachment function of the limiting column 211, and the operation is convenient to improve the loading and unloading efficiency under light load conditions. For heavy-weight load scenarios of concrete pipes, the limiting component 23 can use, but is not limited to, clamps and bolts, to achieve the rigid locking function of the first clamping plate 21 and the second clamping plate 22 through high-strength connection, greatly improving the clamping force to adapt to heavy load requirements and improving the adaptability of the device under different load scenarios.

In this embodiment, an angle adjustment structure 8 is provided between the supporting plate 3 and the first clamping plate 21. The angle adjustment structure 8 includes a rotating plate 81 and a limiting bolt 82. The rotating plate 81 is configured as a vertical rigid straight plate, and an adjusting shaft 811 is horizontally disposed on the inner side of the rotating plate 81.

The lower end of the first clamping plate 21 is fixedly connected to the bearing plate 3, which can be integrally formed or welded to the bearing plate 3. The lower end of the first clamping plate 21 is provided with a plurality of angle adjustment holes 212 arranged in a circular array with the rotating shaft 41 as the axis. The rotating plate 81 is provided with limiting insertion holes 812 corresponding to the angle adjustment holes 212. The limiting bolt 82 passes through the limiting insertion hole 812 and the angle adjustment hole 212. This is used to fix the angle of the rotating plate 81 by cooperating with the limiting bolt 82, the angle adjustment hole 212, and the limiting insertion hole 812. By selecting different angle adjustment holes 212, the horizontal angle can be adjusted in stages, improving the levelness control during pipeline hoisting.

The lower end of the rotating shaft 41 extends out of the lower side of the bearing plate 3 and is fixedly connected to the middle of the connecting platform 42. Platform 42 is rotatably mounted on the lower side of the middle portion of the support plate 3 via a rotating shaft 41, improving the stability of platform rotation.
