[0039] When the clamping arm one 52 needs to clamp and fix the pipeline, the transmission shaft one 503 drives the bidirectional threaded rod one 502 to rotate, both sides of the adjusting plate one 53 are slidably connected with the arm of the support frame one 51, so that the bidirectional threaded rod one 502 drives the adjusting plate one 53 to slide along the arm of the support frame one 51 through the connecting frame one 501, the limiting groove one 54 on the adjusting plate one 53 pushes and extrudes the limiting rod one 55, the limiting rod one 55 drives the clamping arm one 52 connected therewith to move, since the two limiting grooves one 54 are symmetrically arranged, the two clamping arms one 52 move towards each other to clamp the pipeline, when the clamping arm one 52 needs to release the pipeline, by analogy, the bidirectional threaded rod one 502 continues to rotate, the bidirectional threaded rod one 502 drives the adjusting plate one 53 to slide reversely along the arm of the support frame one 51 through the connecting frame one 501, so that the two clamping arms one 52 move reversely to release the pipeline;

[0040] The clamping assembly two 6 comprises a support frame two 61, the bottom of the support frame two 61 is slidably provided with two symmetrically arranged clamping arms two 62, the clamping assembly two 6 further comprises a transmission assembly two 60 and an adjusting plate two 63 slidably arranged on the arm of the support frame two 61, the adjusting plate two 63 is symmetrically provided with two limiting grooves two 64, both of the limiting grooves two 64 are slidably connected with a limiting rod two 65, both of the limiting rod two 65 are fixedly connected with the adjacent clamping arm two 62 at the bottom end, the transmission assembly two 60 comprises a connecting frame two 601 fixedly connected with the bottom end of the adjusting plate two 63, both sides of the connecting frame two 601 are slidably connected with the arm of the hoisting frame 4, the top end of the connecting frame two 601 is threadedly connected with a bidirectional threaded rod two 602, both ends of the bidirectional threaded rod two 602 are rotatably connected with the support frame two 61, one end of the bidirectional threaded rod two 602 is fixedly connected with a transmission shaft two 603;

[0041] When the clamping arms 62 need to clamp and fix the pipelines, the transmission shaft 2 603 drives the bidirectional threaded rod 2 602 to rotate, the two sides of the adjusting plate 2 63 are slidably connected with the inner arms of the support frame 2 61, so that the bidirectional threaded rod 2 602 drives the adjusting plate 2 63 to slide along the inner arms of the support frame 2 61 through the connecting frame 2 601, the limiting grooves 2 64 on the adjusting plate 2 63 push the limiting rods 2 65, the limiting rods 2 65 drive the clamping arms 2 62 connected therewith to move, since the two limiting grooves 2 64 are symmetrically arranged, the two clamping arms 2 62 move towards each other to clamp the pipelines, when the clamping arms 2 62 need to loosen the pipelines, by the same principle, the bidirectional threaded rod 2 602 continues to rotate, the bidirectional threaded rod 2 602 drives the adjusting plate 2 63 to slide reversely along the inner arms of the support frame 2 61 through the connecting frame 2 601, so that the two clamping arms 2 62 move reversely to loosen the pipelines, which will cause a torque, resulting in unstable mechanical response of the hoisting member to loosen;

[0042] The first driving mechanism 7 is used to drive the clamping assembly 1 5 and the clamping assembly 2 6 to clamp or loosen the pipelines, when the first driving mechanism 7 drives the clamping assembly 1 5 to clamp and fix the pipelines, the first driving mechanism 7 drives the clamping assembly 2 6 to loosen the pipelines, when the first driving mechanism 7 drives the clamping assembly 2 6 to clamp and fix the pipelines, the first driving mechanism 7 drives the clamping assembly 1 5 to loosen the pipelines;

[0043] The first driving mechanism 7 comprises a protective shell 7 1 fixedly installed at the top end of the hoisting frame 4, a rotary driving part 1 72 fixedly installed on the inner arm of the protective shell 7 1, wherein the rotary driving part 1 72 comprises but is not limited to a servo motor, a push plate 7 3 and a special-shaped disc 7 4 fixedly installed at one end outside of an output shaft of the rotary driving part 1 72, two sliding plates 7 5 slidably installed at the bottom of the hoisting frame 4, a limiting plate 7 7 fixedly installed at the top of each of the two sliding plates 7 5, a toothing 7 31 arranged at the tail end of the push plate 7 3, a tooth groove 7 6 arranged at the side of each of the two sliding plates 7 5 and matched with the toothing 7 31, an arc-shaped slot with the same arc as the special-shaped disc 7 4 arranged at the side of the limiting plate 7 7 close to the special-shaped disc 7 4, a rack 7 8 fixedly installed at the side away from each other of the two sliding plates 7 5, a one-way gear 7 9 engaged with the side of each of the two racks 7 8, a worm 7 91 fixedly connected with the bottom of each of the two one-way gears 7 9, the two worms 7 91 externally rotatably connected with the hoisting frame 4, and the two worms 7 91 laterally engaged with a worm wheel 7 92, wherein one worm wheel 7 92 is internally slidably connected with the transmission shaft 1 503, and the other worm wheel 7 92 is internally slidably connected with the transmission shaft 2 603, and the two worm wheels 7 92 are externally rotatably connected with the hoisting frame 4;

[0044] The rotating driving member 72 drives the push plate 73 and the special-shaped disc 74 to rotate. The meshing teeth 731 on the push plate 73 push the sliding plate 75 on one side to move through the tooth groove 76, and the rack 78 connected with the sliding plate 75 moves with it, so that the rack 78 drives the one-way gear 79 engaged with it to rotate, the one-way gear 79 drives the worm 791 at the bottom of the one-way gear 79 to rotate, the worm 791 drives the worm wheel 792 on one side of the worm 791 to rotate, so that the worm wheel 792 drives the transmission shaft 503 connected with it to rotate, so that the clamping assembly 5 can control the clamping and loosening of the pipeline, and after the meshing teeth 731 on the push plate 73 are disengaged from the tooth groove 76 on the sliding plate 75, the arc-shaped notch on the limiting plate 77 is in contact with the special-shaped disc 74, so that the sliding plate 75 is limited and cannot move, and due to the transmission connection of the worm 791 and the worm wheel 792, the state of the clamping assembly 5 can be effectively maintained, effectively reducing the falling of the pipeline during hoisting. The rotating driving member 72 drives the push plate 73 and the special-shaped disc 74 to continue to rotate, and the push plate 73 pushes the sliding plate 75 on the other side to move through the tooth groove 76 thereon. Similarly, the transmission shaft 602 rotates, the bidirectional screw rod 602 rotates, and the adjusting plate 63 moves. Similarly, the clamping assembly 6 can control the clamping or loosening state of the pipeline;

[0045] When the clamping assembly 6 is in the clamping state, the rotating driving member 72 drives the push plate 73 and the special-shaped disc 74 to rotate in the opposite direction. Similarly, the meshing teeth 731 on the push plate 73 push the sliding plate 75 on one side to move through the tooth groove 76, so as to drive the rack 78 connected with it to move. At this time, the one-way gear 79 cannot drive the worm 791 at the bottom of the one-way gear 79 to rotate, and the clamping assembly 6 remains in the clamping state. The push plate 73 and the special-shaped disc 74 continue to rotate, and the push plate 73 pushes the meshing teeth 731 to push the sliding plate 75 on the other side to move through the tooth groove 76. Similarly, the transmission shaft 602 rotates, and the clamping assembly 5 clamps the pipeline. When the rotating driving member 72 continues to rotate in the opposite direction, the clamping assembly 5 maintains the clamping state of the pipeline. In this reverse rotation stroke of the rotating driving member 72, the clamping assembly 6 is driven to loosen the pipeline. In this way, one of the clamping assemblies 5 and 6 is always in the clamping state of the pipeline;

[0046] The second driving mechanism 3 is used to drive the clamping assembly 5 or the clamping assembly 6 to move along the inner arm of the hoisting frame 4. The second driving mechanism 3 comprises two rotating driving members 31 fixedly installed on the inner arm of the hoisting frame 4. One end of the output shaft of each of the two rotating driving members 31 is fixedly connected with a screw rod 32. The distal end of each of the two screw rods 32 is rotatably connected with the inner arm of the hoisting frame 4. The outer part of one of the screw rods 32 is threadedly connected with the support frame 51. The outer part of the other screw rod 32 is threadedly connected with the support frame 61.

[0047] When the pipeline is being hoisted upwards, the long pipeline may be obstructed by the building's steel frame structure. In this case, the tilt of the hoisting frame 4 can be controlled by adjusting the slings of the two hoisting components 21. This allows the pipeline to tilt and pass through the building's steel frame structure. However, during this process, the hoisting point deviates from the pipeline's center of gravity, causing a torque that leads to unstable mechanical reactions and swaying, potentially creating safety hazards. To address this, the two rotary drive components 31 in the second drive mechanism 3 control the rotation of the two screws 32, thereby controlling the positions of the clamping components 5 and 6 on the hoisting frame 4. This, combined with the first drive mechanism 7, controls the clamping or releasing state of the clamping components 5 and 6 on the pipeline. This changes the clamping point and thus the hoisting point, reducing swaying and making the hoisting more efficient and safer.

[0048] Example 2:

[0049] An installation method for hoisting electromechanical pipelines in a large-span, high-space-structure structure is provided, applicable to such equipment, comprising the following steps:

[0050] S1. First, determine the hoisting point and lifting position through the preset installation position of the pipeline, and determine the track installation position through the hoisting point and lifting position. Set up warning signs around the hoisting point. The lower chord of the central area of ​​the large span space frame is 22 meters away from the bottom surface and has a wave shape. The space frame is not allowed to bear force on the members. Only the metal ball on the space frame can be used as the force point. The track welding position must be supported by the metal ball of the space frame.

[0051] S2. Next, hoist the track onto the upper chord of the building space frame, and weld and fix the track to the upper chord of the building space frame to make the track horizontal.

[0052] S3. Finally, install the traveling device 22 on the track, connect the hoisting assembly 21 to the hoisting frame 4 via slings, assemble the hoisting equipment, and debug the hoisting equipment.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
