Description

Technical Field

[0001] The invention relates to the field of animal husbandry, and in particular to a pipeline supporting device for water conservancy project construction. Background Art

[0002] Pipe support is a frame used for pipe installation and support. It is mainly used for the installation and fixation of water pipes in water conservancy projects, and is mostly used for the installation of water supply pipes. There are many types of such supports, including ground support and fixed type, wall support and fixed type, and indoor ceiling hanging type;

[0003] Among them, the ground-supported bracket is fixed and installed by clamps of specific sizes and bracket screws when fixing the pipes. This method is troublesome to fix and cannot adapt to the clamping and fixing of pipes of different thicknesses. In addition, during installation, the pipe is placed on the fixed seat by a lifting machine. At this time, if the pipe is not in the ideal installation position and has a slight up and down deviation, it needs to be moved and adjusted. At present, when up and down deviations occur, it is adjusted by adding or removing gaskets on the fixed seat. During this process, the pipe needs to be lifted, which is more laborious. Moreover, the current surface-supported bracket cannot automatically pre-fix the pipe when the pipe is just placed on the fixed seat. In this way, workers need to climb onto the bracket and cooperate with the lifting equipment to pre-fix the pipe. This process is more cumbersome.

[0023] Working principle: When the present invention is used, Figure 5 As shown, when the pipeline is placed by the lifting equipment, the pipeline is pressed on the fixed steel belt 24 between the two swing plates 16. At this time, the fixed steel belt 24 is pressed down under the weight of the pipeline, and the fixed steel belt 24 pulls the two swing plates 16 together. As the two swing plates 16 get closer, the two positioning plates 25 are finally fitted together. When the two positioning plates 25 are fitted together, the two positioning plates 25 can be fixedly connected by bolts. At this time, the pipeline is suspended between the two swing plates 16 by the fixed steel belt 24. In this way, when the pipeline is placed on the bracket device, the fixed steel belt 24 can automatically suspend the pipeline in the air to achieve pre-fixation of the pipeline. When the two swing plates 16 are pulled by the fixed steel belt 24, the two swing plates 16 are respectively The first gear 8 at its bottom end rotates, and when the two first gears 8 rotate, they respectively mesh with the two tooth plates 5 and move in opposite directions. When the two tooth plates 5 move in opposite directions, they respectively mesh with the same second gear 14 through the two racks 13, so that under the action of the second gear 14, the two pulled swing plates 16 will move synchronously.

[0024] When the pipe is placed on the fixed steel belt 24, the pipe squeezes the two limit plates 30 through the two guide plates 31, and then the bottom of the pipe presses against the inner bottom surface of the first U-shaped mounting plate 27 and pushes the first U-shaped mounting plate 27 downward.

Under the action of the first spring 34, the inner bottom surface of the first U-shaped mounting plate 27 is always in contact with the bottom surface of the pipe. When the pipe is suspended between the two swing plates 16 by the fixed steel belt 24 and the position of the pipe is adjusted, first tighten the two second locking nuts 43 on the third threaded rod 41 so that the two second The locking nut 43 is respectively fitted with the top and bottom surfaces of the fixing seat 1, so that the first U-shaped mounting plate 27 can stably hold the bottom of the pipe, and then the first locking nut 37 is screwed to make the first locking nut 37 fit with the positioning block 35, so that the two limit plates 30 can fix and clamp the pipe from both sides of the pipe to prevent the pipe from moving left and right, and then the fourth threaded rod 52 is screwed by the second handle 53, so that the squeezing roller 51 squeezes the pipe from the top of the side of the pipe to prevent the pipe from moving upward, thereby completing the fixing of the pipe, and the locking bolt 48 can be loosened to adjust the height of the squeezing roller 51 through the sliding guide cylinder 46.
