[0023] As Figures 1-4 shown:

[0024] This embodiment provides a pipeline hoisting auxiliary device, including a steel wire rope 100 and a hoisting auxiliary mechanism arranged at the lower end of the steel wire rope 100. The hoisting auxiliary mechanism includes a fixed column 200 arranged at the lower end of the steel wire rope 100. The outer arc surface of the fixed column 200 is provided with uniformly distributed annular rectangular grooves 201. The lower ends of the rectangular grooves 201 are all rotatably connected with rotating columns 202. The lower ends of the inner wall surfaces of the rectangular grooves 201 are all provided with rotating grooves for providing rotational support for the rotating columns 202. The outer arc surfaces of the rotating columns 202 are all provided with swinging support plates 203, and the fixed column 200 provides rotational support for the rotating columns 202

[0025] As Figures 2-3 shown, the middle part of the lower end of the fixed column 200 is provided with an assembly cavity. The lower ends of the rectangular grooves 201 are all communicated with the assembly cavity, and a driving assembly for driving the rotation of the rotating column 202 is further arranged in the assembly cavity.

[0026] As Figures 1-4As shown in the figure, the drive assembly includes a worm gear 204 respectively arranged in the middle of the outer arc surface of the rotating column 202. The rotating column 202 is used to provide rotational support for the worm gear 204. A worm 205 is rotatably connected between the upper and lower wall surfaces of the assembly cavity. Rotation grooves for providing rotational support for the worm 205 are respectively opened in the middle of the upper and lower wall surfaces of the assembly cavity. A through hole adapted to the worm 205 is opened in the middle of the lower end surface of the fixed column 200. The worm gears 204 are all meshed with the worm 205.

[0027] As Figures 2-4 shown in the figure, the drive assembly further includes a knob 206 arranged on the lower extension end of the worm 205. The knob 206 is fixedly installed on the lower end surface of the worm 205, which is convenient for relevant staff to operate.

[0028] As Figures 2-4 shown in the figure, it further includes a positioning assembly. The positioning assembly includes guiding chutes 300 respectively arranged on the inner side surfaces of the swing support plates 203. Sliding plates 301 are slidably connected in the guiding chutes 300. The guiding chutes 300 are used to provide guiding and sliding support for the sliding plates 301. Lead screws 302 are rotatably connected between the upper and lower wall surfaces of the guiding chutes 300. Rotation grooves for providing rotational support for the lead screws 302 are respectively opened on the upper and lower wall surfaces of the guiding chutes 300. Through holes corresponding to the lead screws 302 one by one are opened on the upper surfaces of the swing support plates 203. The lead screws 302 are respectively threadedly connected with screw holes arranged in the middle of the vertically adjacent sliding plates 301.

[0029] As Figures 1-4 shown in the figure, an inverted conical limiting post 500 is slidably connected to the outside of the steel wire rope 100. A sliding hole for slidably connecting with the steel wire rope 100 is opened in the middle of the inverted conical limiting post 500, which is used to limit the upper part of the pipeline.

[0030] The working principle of a pipeline hoisting auxiliary device provided by the present utility model is as follows: First, relevant staff fix the steel wire rope 100 to an external hoisting device, then move the inverted conical limit post 500 to an appropriate position on the steel wire rope 100. Then, the relevant staff pass the fixing post 200 through the pipeline to be hoisted. After that, the relevant staff rotate the worm 205 through the knob 206. When the worm 205 rotates, it drives the rotating column 202, the swinging support plate 203 and its affiliated mechanisms to swing outwards synchronously through the meshing worm gear 204, so as to adjust the angle of the swinging support plate 203, which can better adapt to the shape and size of the pipeline opening. For long pipelines, it can also be hoisted well, greatly increasing the size range of hoistable pipelines and enhancing the versatility of the hoisting auxiliary device. Then, the relevant staff rotate the lead screw 302, and the lead screw 302 drives the sliding plate 301 to move along the sliding plate 301 to ensure that the pipeline obtains sufficient and balanced support and prevent deviation during hoisting. Finally, move the inverted conical limit post 500 again so that the conical part of the inverted conical limit post 500 enters the upper end of the pipeline to position the pipeline and prevent the pipeline from shaking during hoisting. Finally, the operator starts the hoisting device and slowly lifts the pipeline through the steel wire rope 100. After hoisting to the designated position, the operator can reverse the above steps.

[0031] As Figures 1-4 shown, a support ring 400 is provided on the lower end surface of the fixing post 200. The support ring 400 is fixedly welded at the edge of the lower end surface of the fixing post 200, which is used to support the fixing post 200 and play a certain protective role for the knob 206.

[0032] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
