Detailed Description

The following detailed description will describe specific embodiments of the invention in connection with specific examples thereof.

Referring to fig. 1 to 4, the invention relates to a lifting device for a high-rise building vertical shaft pipeline, which comprises a claw-type lifting hook 10, wherein the claw-type lifting hook 10 comprises a fixed bottom plate 11 and a fixed shaft 12 arranged on the center of the fixed bottom plate 11, four uniformly distributed supporting arms 13 are connected to the side wall of the fixed shaft 12 along the circumferential direction, each supporting arm 13 is propped against the fixed bottom plate 11 and horizontally extends out of the fixed bottom plate 11, the supporting arms 13 and the fixed shaft 12 are connected through bolts, so that the supporting arms 13 with corresponding specifications can be replaced when pipelines with different specifications are lifted, and a lifting ring 14 connected with a lifting steel wire rope 30 is fixed at the top of the fixed shaft 12. In addition, the invention relates to a lifting device for a high-rise building vertical shaft pipeline, which comprises an anti-shaking supporting device 20, wherein the anti-shaking supporting device 20 comprises a vertical guide pipe 21 connected with a hoisting steel wire rope 30 and a horizontal guide pipe 22 fixedly connected with the vertical guide pipe 21, the horizontal guide pipe 22 is penetrated with supporting rods 23 with the length being matched with the inner diameter of the pipeline to be hoisted, the supporting rods on the two sides of the horizontal guide pipe are provided with springs with the same length, when the pipeline is hoisted, the pipeline shakes, the supporting rods 23 are impacted by the pipe walls, the supporting rods 23 slide in the horizontal guide pipe 22, the springs 24 are extruded to absorb the energy of the pipe walls impacting the supporting rods 23 in the sliding process of the supporting rods 23, and the supporting rods 23 slide in the horizontal guide pipe under the reaction of the springs 23 and are reset gradually.

Limiting blocks are arranged on two sides of each supporting arm 13 to form limiting grooves 15, and the supporting arms 13 are prevented from moving in the horizontal direction when the pipeline is hoisted. In addition, the upper side of the supporting arm 13 is provided with corresponding limiting blocks 16 according to the diameter specification of the hoisting pipeline so as to clamp the inner side and the outer side of the bottom end of the pipeline, so that the pipeline is ensured not to be loosened relative to the claw type lifting hook 10 during hoisting, and the safety of hoisting the pipeline is improved.

As a preferable mode of the embodiment of the invention, the bottom of the fixed bottom plate 11 is provided with the trundle 17, when the pipeline gradually turns to the vertical state from the horizontal state, the dragging of the bottom of the pipeline is changed into the rolling of the trundle, so that the guiding function is realized, and the deformation and the damage of the pipeline caused by the friction between the pipeline and the ground are prevented.

Referring to fig. 5, after one end of the hoist wire rope 30 is connected with the hoist ring 14 on the claw hook 10, the other end passes through the vertical guide pipe 21 of the anti-shaking support device 20 and is connected with the hoisting apparatus, and the anti-shaking support device 20 is positioned in the inner wall of the upper end of the pipeline when the pipeline is hoisted by locking the shackle 25 under the anti-shaking support device 20 to fix the anti-shaking support device 20 at a proper position of the hoist wire rope 30. The claw type lifting hook 10 penetrates through the upper port of the pipeline, and the supporting arm 13 is connected with the fixed shaft 12 through bolts, so that the supporting arm 13 can be folded upwards in a rotating mode and smoothly penetrates through the inner wall of the pipeline, and when the claw type lifting hook 10 penetrates out of the other end of the pipeline, the supporting arm 13 is unfolded under the action of gravity and clamps the bottom end of the pipeline through the limiting block 16. The support arm 13 has the ability to support the weight of the pipe in the suspended state, since the support arm 13 is limited downward by the fixed base plate 11. After the claw type lifting hook 10 is in place, the pipeline is lifted upwards, the pipeline is converted from a horizontal state to a vertical state, at the moment, the dragging of the bottom of the pipeline is changed into the rolling of the castor 17 by the castor 17, and the pipeline can be prevented from being deformed and damaged due to friction between the pipeline and the ground while the labor is saved. In the process of hoisting the pipeline, the anti-shaking supporting device 20 reduces the left-right shaking of the pipeline, avoids the impact on the hoisting steel wire rope 30, and ensures the vertical state of the pipeline in the hoisting process. After the pipeline is hung to the position, and is connected with the pipeline at the upper part, the hanging steel wire rope 30 is loosened, and the claw type lifting hook 10 automatically loosens the hook. After the claw type lifting hook 10 is sent to the bottom layer, the working procedures are repeated, and then the next section of pipeline can be lifted. When the specification of the support arm 13 cannot meet the pipeline hoisting of the next stage, the support arm 13 with the proper specification can be replaced, and the hoisting operation is repeated.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
