[0002] With the rapid development of urbanization, the supporting pipelines are also increasing. In particular, when some steel vertical pump pipes are installed and fixed to the first floor slab, in order to ensure the stability of the vertical pump pipes, auxiliary devices are usually used to install and fix the vertical pump pipes during installation to avoid the risk of the vertical pump pipes falling due to the long-term effects of gravity and water flow.

[0003] Chinese patent publication number CN217583483U discloses a vertical pipe fixing frame, which is mainly fixed by locking the fixing frame body and the first fixing frame and the second fixing frame on the pipe with bolts.

[0004] Although the above structure can enhance the stability of the pipeline, in actual use, more bolts are used, the operation of the staff is cumbersome, the fixing efficiency is low, and the size of the center hole of this fixing structure is fixed, so it cannot be applied to the installation of pipelines of various specifications and sizes. Utility Model Content

The existing fixing device is generally fixed by riveting with bolts, but this installation method is cumbersome to assemble and disassemble, which affects the construction efficiency; 2. The internal structure of the existing fixing device is fixed in size, resulting in a single installation model and poor applicability.

[0006] The utility model is realized by the following technical solutions:

[0007] A pipeline fixing device comprises a base, which is circular and has a through hole in the center, a pipeline is vertically arranged in the through hole, a plurality of slots are arranged on the inner side wall of the through hole, a card block is arranged inside each of the slots, an adjustment plate is also movably installed in the base and arranged below the card block, a slide groove is provided on the top surface of the adjustment plate, a slider is provided at the bottom of the card block and is inserted into the slide groove, and several of the slide grooves are arranged in a circular array with the center of the base and abut against the outer wall of the pipeline, and a transmission assembly is also provided at the bottom of the adjustment plate, and the transmission assembly extends to the outside of the base and is connected to an adjustment handle.

When the annular connecting plate is inserted into the groove, the arc-shaped surface of the block just abuts against the outer wall of the pipe.

[0010] Furthermore, the end surface of the block and the inner wall of the groove are both provided with anti-skid pads, and the anti-skid pads are rubber pads with wavy anti-skid patterns on the surface.

[0011] Furthermore, the adjustment plate is an annular plate, and a ball bearing is provided between the adjustment plate and the base. Two ball bearings are provided and have different inner diameters. The ball bearing with a larger inner diameter is arranged on the outer ring of the adjustment plate and fixedly connected to the outward inner wall of the base, and the ball bearing with a smaller inner diameter is arranged on the inner ring of the adjustment plate and fixedly connected to the inward inner wall of the base.

[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Combination Figure 1-4 As shown, a pipeline fixing device comprises:

[0025] The base 1 is a circular metal base 1, with a through hole at the center, and the pipe is vertically inserted into the through hole;

[0026] The slots 2 are provided in three numbers and are arranged on the inner wall of the through hole in a circular array with the center of the base 1;

[0027] The clamping block 3 is slidably inserted into the slot 2 and fixed by abutting the outer wall of the pipe with its side wall;

[0028] The adjusting plate 4 is used to adjust the distance between the clamping block 3 and the center of the base 1, so as to fix or disassemble the pipeline by using the clamping block 3;

[0029] The transmission assembly 5 is disposed at the bottom of the adjustment plate 4 and is used to drive the adjustment plate 4 to rotate.

[0030] Specifically, flanges are provided on the four sides of the bottom of the base 1, and bolt holes are opened on the flanges. Expansion bolts are provided in the bolt holes to fix the base 1 to the top surface of the floor, so that the through hole in the center of the base 1 is concentrically arranged with the circular hole preset in the floor.

[0031] The card block 3 is set to be rectangular, and the front and rear end faces of the card block 3 are set to be arc-shaped surfaces, and can be completely retracted into the inside of the base 1 along the slot 2. The adjusting plate 4 is arranged below the card block 3, and the adjusting plate 4 is an annular plate, and a slide groove 41 is provided on the top surface. The slide groove 41 is arranged in a vortex shape and is gradually opened outward with the circular hole at the center of the adjusting plate 4 as the starting point. The bottom of the card block 3 is exactly provided with two sliders 31, and the sliders 31 are arc-shaped blocks and fit the inner wall of the slide groove 41. Therefore, when the adjusting plate 4 rotates, the sliders 31 will be affected by the slide groove 41. At the same time, the card block 3 body is fixed by the slot 2, so the entire card block 3 can only move toward the center of the base 1 with the rotation of the slide groove 41 to complete the clamping of the pipe, or move away from the center of the base 1.

[0032] In the above structure, the three blocks 3 are all driven by the same adjustment plate 4, so the movement of the three blocks 3 is synchronous. This clamping and fixing method has an automatic centering effect, and can correct the pipeline body during the fixing process to prevent its installation from being tilted, so that the pipeline always remains vertical to the floor, and the force around the pipeline is more uniform. In addition, the center clamping distance can be adjusted according to the specific model used during the adjustment process, and it has strong applicability.

[0033] In order to further strengthen the connection effect between the clamping block 3 and the pipeline, a groove 32 should be transversely arranged on the end face facing the center of the base 1, and an annular connecting plate 6 should be welded on the outer wall of the pipeline at the same time. When the ends of the three clamping blocks 3 are all in contact with the pipe wall, the annular connecting plate 6 is just clamped in the groove 32.

[0034] In actual use, in order to prevent damage to the pipeline due to the clamping process, an anti-skid pad should be arranged on the end face of the clamping block 3. The anti-skid pad can be a rubber pad with anti-skid patterns on the surface. At the same time, some anti-skid pads should be set on the upper and lower inner walls of the groove 32 so that the elastic properties of the rubber can be used for interference fitting to enhance the stability of the pipeline.

[0035] Ball bearings are provided on both the inner and outer surfaces of the adjustment plate 4 , one surface of which is fixedly connected to the inner and outer side walls of the adjustment plate 4 , and the other surface is connected to the inner wall of the base 1 , so that the adjustment plate 4 can rotate flexibly inside the base 1 .

[0036] The transmission assembly 5 includes a driving gear 51 arranged at the bottom of the adjustment plate 4, and an adjusting shaft 52 is arranged on one side of the driving gear 51. The adjusting shaft 52 and the driving gear 51 are meshed with each other and are arranged to form a worm gear structure. Both ends of the adjusting shaft 52 are rotatably connected to the adjustment plate 4 respectively, one end of which extends to the outer wall of the base 1 and is provided with a hexagonal hole on its end face, and an adjusting handle is inserted in the hexagonal hole. Therefore, the entire adjustment plate 4 can be driven to rotate through the adjustment plate 4, and this driving method has a self-locking function, which can effectively prevent the clamping structure from loosening when it is disturbed by external interference, making it more convenient to use, and the entire adjustment process only requires one adjusting shaft 52 to complete, which greatly simplifies the operation steps and improves construction efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
