[0039] It should be noted that in the following embodiments, the axial direction of the pipe to be fixed is taken as the front-to-back direction, and the radial direction of the pipe to be fixed where the horizontal plane is located is taken as the left-to-right direction, so as to facilitate detailed description of this embodiment.

[0040] Example 1

[0041] like Figures 1-7 The adjustable pipe support shown includes a fixed base 1, a sliding base 2 and a pipe fixing assembly 3. The pipe fixing assembly 3 is fixedly connected to the top of the sliding base 2, and the sliding base 2 can be slid back and forth and connected to the top of the fixed base 2. The sliding base 2 can adapt to the axial deformation of the pipe by sliding back and forth above the fixed base 2.

[0042] Specifically, the fixed base 1 is as follows Figures 1-5As shown, the middle part is provided with a front and rear direction distribution sliding groove 101, the sliding groove 101 is fixedly connected with a length along the front and rear direction distribution guide rail 102, and two groups of guide grooves 104 are symmetrically arranged at the front and rear ends of the sliding groove 101. The guide groove 104 is fixedly connected with the guide shaft 105, the length of the guide shaft 105 is distributed along the front and rear direction, the outer side is fixedly connected with the guide groove 104 side wall, the other end is distributed towards the sliding groove 101, and in this embodiment, in the height direction, the guide shaft 105 is located above the guide rail 102, and the guide groove 104 is communicated with the sliding groove 102, and the inner side of the guide shaft 105 extends into the sliding groove 101 by a certain length.

[0043] The sliding base 2 is as shown in the figure Figure 6 The upper end surface is provided with an adjusting groove 201, and the left and right screw mounting holes 202 are distributed through the adjusting groove 201. The lower part of the sliding base 2 is fixedly connected with a sliding block 203, the sliding block 203 is slidably connected with the guide rail 102, and the height of the sliding block 203 is the same as the depth of the sliding groove 101. The upper end surface of the fixed base 1 and the lower end surface of the sliding base 2 are smooth surfaces, so as to reduce the friction resistance between the fixed base 1 and the sliding base 2 when the sliding block 203 and the guide rail 102 are slidably connected.

[0044] The pipeline fixing assembly 3 is composed of a first fixing assembly 301, a second fixing assembly 302 and an adjusting screw 303. The adjusting screw 303 is rotatably connected in the screw mounting hole 202 through a bearing. The length of the adjusting screw 303 is distributed along the left and right directions.

[0045] When the sliding base 2 is mounted in cooperation with the fixed base 1, a first buffer spring 106 is coaxially sleeved outside the guide shaft 105, and the length direction two ends of the first buffer spring 106 are respectively connected with the side wall of the sliding groove 104 and the front and rear side walls of the sliding base 2. Through the arrangement of the guide shaft 105 and the first buffer spring 106, a certain degree of buffering can be achieved for the sliding between the two, so as to avoid the collision between the sliding base 2 and the fixed base 1 due to the large axial deformation of the pipeline caused by the instantaneous thermal expansion and cold shrinkage, thereby affecting the fixing effect of the pipeline fixing assembly 3 on the pipeline. In addition, when the temperature of the pipeline returns to the initial state, the first buffer spring 106 can drive the sliding base 2 to reset by using its elasticity.

[0046] In addition, two sets of limiting assemblies are arranged between the sliding base 2 and the fixed base 1, and the two sets of limiting assemblies are symmetrically arranged in the front and rear directions in the sliding groove 101. Each set of limiting assembly includes two limiting plates 103, which are symmetrically arranged left and right, and the two limiting plates 103 are respectively fixedly connected with the left and right side walls of the sliding groove 101. The position of the limiting plate 103 is the limit position of the axial deformation of the pipeline to be fixed. Through the arrangement of the limiting plate 103, the situation that the pipeline is separated from the original conveying pipeline due to excessive deformation of the pipeline can be avoided, and the stability and reliability of the overall conveying pipeline can be improved.

[0047] In addition, in the embodiment, the inner side surface of the fixed arc-shaped plate 305 is coated with anticorrosive paint to reduce the corrosion of the fixed component caused by the environment during the fixing of the pipeline.
