Description

A pipe lifting device for construction

Technical Field

The utility model relates to the technical field of building construction, in particular to a pipeline hoisting device for building construction.

Background Art

Construction refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Pipe lifting is a very important link and requires the use of lifting tools. Common pipe lifting tools include hooks, slings, rings, clamps, etc.

There may be some problems when using traditional steel ropes to lift steel pipes. Especially when lifting larger steel pipes, traditional lifting ropes may not be able to lift them stably. In addition, during the process of lifting the steel pipe upwards, traditional lifting ropes may be affected by external factors and sway, which may cause the steel pipe to fall off, and the safety is poor.

A Chinese patent for a steel pipe lifting sling for construction (publication number CN218371495U) is proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: by setting a clamping mechanism and a driving mechanism, the worker can put the steel pipe into the device to adapt to most sizes and clamp it quickly and conveniently. At the same time, the steel rope in the driving device drives the sliding plate to move, so as to reduce the influence of external factors such as wind force, and the safety factor is high. However, each lifting requires manual transportation of the pipe to the installation plate, and the transportation process requires great effort and time, which makes the lifting process more cumbersome and labor-intensive. In addition, the pipe also needs to be moved down during the unloading process, which is extremely inconvenient to use.

In this embodiment, it is convenient to balance the gravity at both ends of the lifting frame 25, prevent the lifting frame 25 from tilting or having a tilting tendency to cause wear to the support frame, and make the lifting frame 25 more stable. At the same time, when the sling is released, the lifting frame 25 can move downward under the action of gravity.

The following is a detailed description of the working principle of the pipe lifting sling used in construction.

As shown in Figures 1-5, before hoisting, the side where the folding support frame 23 of the device is located is pushed close to the side of the pipeline. During the pushing process, the first motor 3 is controlled to work, driving the driving shaft 5 and the screw 6 to rotate, thereby driving the first slider 7 to move, and then driving the movable support frame 13 to move through the movable frame 8. At this time, the universal wheel 24 at the bottom of the support base 14 and the universal wheel 24 at the bottom of the movable support frame 13 form a four-corner support to provide support for the crossbeam 2; the rotation of the driving shaft 5 drives the first bevel gear 9 to rotate, and drives the second bevel gear 9 through meshing 11 rotates, thereby driving the first pulley 12 to rotate, and driving the second pulley 40 to rotate through the transmission belt, so that the connecting rod 21 rotates and drives the two worms 20 to rotate, and the worm 20 drives the worm wheel 22 to rotate through meshing, and the transmission process has a large transmission ratio. Therefore, the folding support frame 23 starts to fold off the ground when the movable support frame 13 has a certain distance from the support base 14. After the folding support frame 23 is completely folded off the ground, the relative distance between the movable support frame 13 and the support base 14 is relatively far, and its state is shown in FIG. 3, that is, the preparation work is completed;

The push device is controlled to work at the same time, so that the device moves so that the pipeline is relatively close to the central position below the beam 2. At the same time, the first motor 3 works in this process to make the movable support frame 13 gradually move to the side close to the support base 14, and gradually unfold the folding support frame 23. Before the folding support frame 23 is fully unfolded, the movable support frame 13 is sufficient to stabilize the beam 2 until the pipeline is located at the central position below the beam 2. Then the first motor 3 is controlled to work until the folding support frame 23 is fully unfolded. At this time, the movable support frame 13 is relatively close to the fixed support frame 1. At this time, the hoisting operation can be started;

During the hoisting process, the second motor 15 is controlled to work, driving the rotating rod 16 to rotate, so that the reel 17 rotates, the sling is released, and the lifting frame 25 descends under the action of gravity until the two clamping plates 31 are flush with the pipeline, and the pipeline positioning can be started. The third motor 32 is controlled to work, driving the third pulley 33 to rotate, and the fourth pulley 34 is driven to rotate through the pulley transmission, so that the bidirectional screw rod 28 rotates, so that the two second sliders 29 move toward the side close to each other, and then drive the two clamping plates 31 to move toward the side close to each other, clamping the pipeline, and then control the second motor 15 to rotate in the opposite operation to the above, so that the reel 17 reels the sling and lifts the pipeline at the same time, that is, the hoisting of the pipeline is completed;

Unloading process: move the entire sling to the position where unloading is required, and then control the second motor 15 to drive the rotating rod 16 to rotate, so that the winding disk 17 rotates, the sling is released, and the lifting frame 25 descends under the action of gravity until the pipeline touches the ground, and then control the third motor 32 to work, so that the clamping plate 31 moves to the side away from each other, releases the pipeline, and after the lifting frame 25 is retracted upward, the sling is moved away to complete the lifting process. The pipeline lifting process is stable, which greatly improves the safety and stability of the pipeline lifting process, which is beneficial to practical applications.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
