A pipeline hoisting device including a parallelogram bracket, a first hanging boom and a second hanging boom is designed. The gravity of the pipeline itself uses the upward displacement of the upward and downward inflection points of the parallelogram bracket, and drives the third hanging boom and the fourth hanging boom to clamp the pipe from both sides to ensure the stability of the pipeline during the lifting process.
Through this device, the pipes are more stable and not easy to shake after lifting, which improves the safety of lifting.

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] like Figure 1 and Figure 2As shown, a pipeline lifting device used in water conservancy and hydropower projects includes a parallelogram bracket 1, the upper and lower inflection points of the parallelogram bracket 1 are respectively connected to the first hanger 2 and the second hanger 3, the left and right inflection points of the parallelogram bracket 1 are respectively connected to the third hanger and the fourth hanger, and the third hanger and the fourth hanger are installed on the second hanger 3 in a transverse sliding manner, the second hanger 3, the third hanger and the fourth hanger are all in an "L" shape, and a lifting ring 4 is arranged at the top of the first hanger 2.
[0018] When hoisting the pipeline, the horizontal part of the bottom end of the second hoisting rod 3 is inserted into the pipeline from the pipeline mouth, and then the pipeline is lifted upward. The first hoisting rod 2 drives the upper inflection point of the parallelogram bracket 1 to move upward. At this time, the left and right inflection points of the parallelogram bracket 1 are tilted and moved upward. In this process, the parallelogram bracket 1 drives the third and fourth hoisting rods to approach the pipeline and clamp the pipeline. In the subsequent process of lifting the pipeline, the pipeline's own gravity is used as the force to stretch the parallelogram bracket 1 up and down, so that the third and fourth hoisting rods clamp the pipeline from both sides, thereby improving the stability of the hoisted pipeline, effectively improving the shaking of the pipeline, and improving the safety of the hoisted pipeline.
[0019] The first suspension rod 2 is slidably mounted on the top of the second suspension rod 3. The third suspension rod and the fourth suspension rod both include an upper rod body 5 and a lower rod body 6. The upper rod body 5 is slidably mounted on the top of the lower rod body 6. The left and right inflection points of the parallelogram bracket 1 are rotatably connected to the two upper rod bodies 5 respectively.
[0020] Through the above arrangement, in the initial stage of lifting the pipeline, under the action of the gravity of the pipeline, the first suspension rod 2 will move upward on the top of the second suspension rod 3, and the upper rod body 5 will move upward on the top of the lower rod body 6. During this process, the pipeline will remain on the ground, and the parallelogram bracket 1 will be gathered to the middle, and the lower rod body 6 will move laterally toward the pipeline and clamp the pipeline.
[0021] A through slot 7 is provided on the lower rod body 6, and a cross bar 8 is slidably inserted into the through slot 7, and the opposite ends of the two cross bars 8 are fixedly connected to the side of the second suspension rod 3. When the upper rod body 5 moves upward along the lateral turning point of the parallelogram bracket 1, the lower rod body 6 is guided by the through slot 7 and the cross bar 8, and only moves laterally toward the side of the pipeline, thereby achieving the function of clamping the pipeline.
[0022] A return spring 9 is provided between the bottom end of the upper rod body 5 and the top end of the lower rod body 6, and between the bottom end of the first suspension rod 2 and the top end of the second suspension rod 3. Specifically, in the initial state, the return spring 9 makes the first suspension rod 2 and the second suspension rod 3 as a whole, the third suspension rod as a whole, and the fourth suspension rod as a whole all in the shortest state.
[0023] The first limit block 10 and the second limit block 11 are fixedly installed on the first suspension rod 2 and the second suspension rod 3 respectively, and the first limit block 10 and the second limit block 11 are respectively located on the inner side of the upper and lower inflection points of the parallelogram bracket 1, for limiting the inward retraction angle of the upper and lower inflection points of the parallelogram bracket 1.
[0024] Specifically, in the process of lifting the pipeline, after the parallelogram bracket 1 is folded in the row, the two upper sides of the parallelogram bracket 1 are clamped on both sides of the top of the first limit block 10, and are limited and supported by the first limit block 10. At the same time, the two lower sides of the parallelogram bracket 1 are clamped on both sides of the bottom end of the second limit block 11, and are limited and supported by the second limit block 11. Therefore, after the pipeline is lifted, the state of the parallelogram bracket 1 can be fixed, further improving the stability and safety of the pipeline lifting.
[0025] The vertical parts of the first suspension rod 2, the second suspension rod 3, the third suspension rod and the fourth suspension rod are all located outside the pipe opening, and the first suspension rod 2, the second suspension rod 3, the third suspension rod and the fourth suspension rod are located on the same longitudinal plane, the upper two sides of the parallelogram bracket 1 are located on the outer side of the first suspension rod 2, and the lower two sides of the parallelogram bracket 1 are located on the rear side of the first suspension rod 2. In this way, the four sides of the parallelogram bracket 1 are symmetrically distributed on the front and rear sides of the first suspension rod 2 in the length direction of the pipe to improve the balancing effect.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
