Technical Field

[0001] The utility model relates to the technical field of pipeline lifting, in particular to an auxiliary lifting device for pipeline installation. Background Art

[0002] Pipe lifting devices in water conservancy construction are equipment used to lift, transport and install pipes and pipe components in water conservancy projects. They play an important role in water conservancy project construction, helping to improve work efficiency, reduce labor costs and ensure that pipes are installed safely and accurately in designated locations.

[0003] When the pipe lifting device in the prior art is actually used, the lifting of the pipe is achieved by a lifting frame on the lifting device that can be raised and lowered. During operation, the staff first adjusts the lifting frame to the bottom of the lifting device so that the lifting frame is in contact with the ground, and then at least two staff members lift the pipe onto the lifting frame by lifting. Finally, the pipe is lifted by controlling the position of the lifting frame. Since the operator needs to lift the pipe onto the lifting frame by lifting, there is a risk of human handling, which may cause injury to the worker, especially if the weight is too heavy or the posture is improper during the handling process. In addition, since the operation requires the participation of multiple people and involves multiple steps, the efficiency of the entire lifting process may be relatively low, which may lead to insufficient production efficiency, especially when frequent lifting is required.

[0004] Therefore, it is necessary to design an auxiliary lifting device for pipeline installation to solve the above problems. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-2 , an auxiliary lifting device for pipeline installation, including a frame 1, a motor 2 is installed on the top of the frame 1, the output shaft of the motor 2 is connected to a screw rod 3, the bottom end of the screw rod 3 is rotatably installed on the frame 1, a guide rod 4 is fixed on the frame 1, a lifting seat 5 is threadedly sleeved on the screw rod 3, and the lifting seat 5 is slidably sleeved on the guide rod 4. When the motor 2 is running, it can drive the screw rod 3 to rotate. Under the limiting action of the guide rod 4, the screw rod 3 can drive the lifting seat 5 to move upward when it rotates. When the lifting seat 5 moves upward, it can apply force to both ends of the pipeline through two slings 61, thereby achieving the lifting of the pipeline;

[0020] Two fixing components are provided on the lifting seat 5, which include a sling 61, a mounting plate 62, a sliding plug 63, several connecting rods 64, several pressure plates 65 and several springs 66. One end of the sling 61 is fixed to the lifting seat 5, and the other end is fixed to the mounting plate 62. Several symmetrically arranged cavities are opened inside the mounting plate 62, and the several cavities are connected by connecting ports. Several sliding plugs 63 are respectively slidably connected in the several cavities. One end of several connecting rods 64 is respectively fixedly connected to the several sliding plugs 63, and the other ends extend to the outside of the corresponding cavities. Several pressure plates 65 are respectively fixedly connected to the other ends of several connecting rods 64.

One end of several springs 66 is respectively connected to the several sliding plugs 63, and the other end is respectively connected to the inner wall of the several cavities.

[0021] The frame 1 is provided with a liquid injection assembly, which includes a liquid storage tank 71, a cylinder 72, a slide 73 and two connecting pipes 74. The liquid storage tank 71 is fixed to the bottom end of the frame 1, the cylinder 72 is mounted on the liquid storage tank 71, the slide 73 is sealed and slidably connected to the inner surface of the liquid storage tank 71, the telescopic end of the cylinder 72 is fixedly connected to the slide 73, one end of the two connecting pipes 74 is connected to the liquid storage tank 71, and the other end of the two connecting pipes 74 is respectively connected to one of the cavities in the two mounting plates 62.

When the slide 73 moves downward, it can press the liquid in the liquid storage tank 71 into several cavities through the two connecting pipes 74. Then, the liquid will push the several slide plugs 63 to move. When the several slide plugs 63 move, they can drive the several connecting rods 64 to move, so that the several clamping plates 65 move synchronously until the several clamping plates 65 are tightly pressed against the pipe walls at both ends of the pipe.

[0023] When the pipe lifting device for water conservancy construction proposed by the present invention is in use, the staff pushes the frame 1 to one side of the pipe, and then places the two mounting plates 62 at both ends of the pipe respectively, and then starts the cylinder 72. When the cylinder 72 is running, it can drive the slide plate 73 to move downward. When the slide plate 73 moves downward, it can press the liquid in the liquid storage tank 71 into the plurality of cavities through the two connecting pipes 74. Then, the liquid will push the plurality of slide plugs 63 to move. When the plurality of slide plugs 63 move, it can drive the plurality of connecting rods 64 to move, so that the plurality of clamping plates 65 move synchronously until the plurality of clamping plates 65 are tightly pressed against the pipe walls at both ends of the pipe. At this time, the staff closes the cylinder 72. In this case, the plurality of clamping plates 65 can fix the pipe together, so that the lifting frame 2 can drive the pipe to move upward;

[0024] Next, the staff starts the motor 2. When the motor 2 is running, it can drive the screw rod 3 to rotate. Under the limiting action of the guide rod 4, the screw rod 3 can drive the lifting seat 5 to move upward when it rotates. When the lifting seat 5 moves upward, it can apply force to both ends of the pipeline through the two slings 61, thereby lifting the pipeline. Based on the above process, the staff can use two fixing components to fix the two ends of the pipeline, and there is no need to lift the pipeline onto the lifting seat 5 by lifting. The operation is convenient and saves physical effort.
