DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-8 The present invention provides a technical solution: a pipeline hoisting device, including a hanging plate 1, and further comprising:

[0033] The boom component 2 is symmetrically arranged on the hanging plate 1 and is used to lift the pipeline;

[0034] The clamping assembly 3 is provided on the side of the boom component 2 away from the hanging plate 1 and is used to clamp and fix the pipe;

[0035] The tilt detection unit 4 is provided on the hanging plate 1 and is used to detect the tilt of the pipeline when it is hoisted;

[0036] The adjusting component 5 is provided on the clamping assembly 3 and is used to adjust the clamping position of the pipe when the pipe is tilted. The clamping assembly 3 is placed on the pipe to be lifted, the crane lifts the hanging plate 1, and the clamping assembly 3 is driven by the boom assembly 2 to approach the pipe, clamp the pipe and fix it, and then lift the pipe. The tilt detection unit 4 can detect the inclination of the pipe. When the pipe is tilted, the tilt detection unit 4 will drive the adjusting component 5 to adjust the fixing position of the clamping assembly 3 on the pipe, so that the clamping assembly 3 is fixed at the center of gravity of the pipe, reducing the tilt and shaking of the pipe when the crane is transporting the pipe, which may cause harm to the workers.

[0037] In one embodiment, the clamping assembly 3 includes a fixing plate 31 mounted on the boom member 2. A curved clamping plate 32 is mounted on the fixing plate 31. A support plate 33 is mounted on the side of the clamping plate 32 facing away from the boom member 2. The clamping plate 32 includes a placement slot 34 for mounting the clamping assembly 3. With this design, the support plates 33 at the lower ends of the two clamping plates 32 are staggered. When the clamping plates 32 clamp the pipe, the support plates 33 wrap around and support the pipe, thereby further stabilizing the pipe when the adjustment member 5 adjusts its mounting position.

[0038] In one embodiment, the tilt detection unit 4 includes an adjustment frame 41 rotatably mounted on the hanging plate 1. A guide rod 42 is disposed at the lower end of the adjustment frame 41. A gravity ball 43 is disposed at the lower end of the guide rod 42. The guide rod 42 is passed through a mounting frame 44. Inside the mounting frame 44, detection components 45 for detecting the inclination of the pipeline are mounted on both sides of the guide rod 42. With this design, when the pipeline tilts, the gravity ball 43 will swing along the position of the adjustment frame 41 toward the side where the pipeline is tilted. During the swinging of the gravity ball 43, the guide rod 42 will squeeze the detection component 45. The detection component 45 then activates the adjustment component 5, which then adjusts the installation position of the pipeline.

[0039] In one embodiment, the detection component 45 includes connecting plates 451 provided on both sides of the mounting frame 44 and a moving rod 452 passing through the connecting plates 451. A moving block 453 is provided on one side of the moving rod 452 close to the guide rod 42, and a pressing plate 456 is provided on the other side. A micro switch 455 is provided at the position of the pressing plate 456 corresponding to the mounting frame 44. With this design, the guide rod 42 squeezes the moving block 453. Since the moving block 453 is arranged in an arc shape, it can push the moving rod 452 to move when squeezed by the guide rod 42, and then the pressing plate 456 squeezes the micro switch 455. One of the two micro switches 455 drives the adjustment component 5 to rotate forward, and the other drives the adjustment component 5 to rotate reversely, so that the pipeline can be adjusted accordingly according to the inclination of the pipeline.

[0040] In one embodiment, an elastic member 454 is sleeved on the movable rod 452 between the movable block 453 and the connecting plate 451. This design can drive the pressing plate 456 to reset, so that after the position of the pipeline is leveled, the micro switch 455 is stopped from being pressed, and the adjusting component 5 stops adjusting the pipeline.

[0041] In one embodiment, the adjustment component 5 includes a plurality of rotating shafts 54 spaced apart within the placement slot 34 and a motor 51 electrically connected to a microswitch 455. The bottom end of the rotating shaft 54 is rotatably mounted on the bottom wall of the placement slot 34. The top of the rotating shaft 54 passes through the top wall of the placement slot 34 and is provided with a gear 53. The gears 53 are linked together by a chain 56. A protective box 52 is provided outside the gears 53. The motor 51 is mounted on the protective box 52, and the output end of the motor 51 passes through the protective box 52 and is fixedly connected to one of the gears 53. With this design, when the pipeline tilts to the left, the guide rod 42 presses the left movable block 453, the pressing plate 456 activates the left microswitch 455, and the motor 51 drives the rotating shaft 54 to rotate forward, which in turn drives the gear 53 to rotate. Then, driven by the chain 56, the pipeline moves to the right, thereby leveling the pipeline. And vice versa.

[0042] In one embodiment, a guide roller 55 is sleeved on the rotating shaft 54. With this design, the guide roller 55 is connected to the outer wall of the pipe. During the rotation of the rotating shaft 54, the guide roller 55 drives the pipe to move, thereby adjusting the clamping position of the clamping plate 32 on the pipe.

[0043] In one embodiment, the diameter of the guide roller 55 gradually decreases toward the side close to the motor 51, corresponding to the bending angle of the clamping plate 32. This design can increase the contact area between the guide roller 55 and the inner wall of the pipe, thereby improving the stability of the pipe clamping.

[0044] In one embodiment, the guide roller 55 is located on the opposite side of the two clamping plates 32 and protrudes from the clamping plates 32. This design makes it easy to adjust the position of the pipeline and reduce the friction between the pipeline and the clamping plates 32.

[0045] In one embodiment, wear-resistant particles are provided on the end surface of the guide roller 55. This design can increase the friction between the guide roller 55 and the pipeline, thereby improving the stability of the pipeline fixation and facilitating the adjustment of the installation position of the pipeline.

[0046] In one embodiment, fixing frames 11 are symmetrically provided on both sides of the hanging plate 1, a mounting groove 12 is provided in the middle of the hanging plate 1, a lifting ear 13 is provided on the upper part of the hanging plate 1 located at the mounting groove 12, the tilt detection unit 4 is installed inside the mounting groove 12, and the crane is fixed to the lifting ear 13 for lifting the entire lifting component.

[0047] In one embodiment, the boom component 2 includes a boom arm 21, which is rotatably arranged in the fixed frame 11. The inner middle parts of the two boom arms 21 are fixedly connected by a reinforcing plate 22. The inner ends of the two boom arms 21 are rotatably connected by a connecting rod 23. A connecting frame 25 is fixedly arranged at the lower end of the boom arm 21. The connecting frame 25 is fixedly connected to the fixed plate 31. A limiting component 24 is provided on the outer side of the boom arm 21. The limiting component 24 includes a mounting block 241 arranged on the fixed frame 11, a locking rod 242 rotatably sleeved on the mounting block 241, and a fixing rod 243 arranged on the boom arm 21. The locking rod 242 is clamped with the fixing rod 243. With this design, when it is necessary to use the lifting equipment, the locking rod 242 is removed from the fixing rod 243 to release the restriction of the locking rod 242 on the lifting equipment, and then the clamping plate 32 is clamped on the outer wall of the pipe. The crane lifts the hanging plate 1 and the lifting arm 21 rotates so that the clamping plates 32 are close to each other to clamp and fix the pipe.
