Description

Technical Field

[0001] The utility model relates to the technical field of chemical pipelines, in particular to an installation support structure for chemical pipelines. Background Art

[0002] During the installation of chemical pipelines, it is necessary to dig a tunnel in advance and install a support in the tunnel. The pipeline is fixed in the support through the support to enhance the installation strength of the pipeline and prevent the pipeline from shifting. The inner wall of the tunnel is a geotechnical structure, which can provide good support for the support structure. However, the existing support diameter is generally larger than the diameter of the chemical pipeline, and it is impossible to support and fix chemical pipelines with different diameters, which will affect the stability of the chemical pipeline during operation and shorten the service life of the pipeline. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the disadvantage that it is not convenient to support and fix chemical pipelines with different diameters in the prior art, and a support structure for chemical pipeline installation is proposed.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Design an installation support structure for chemical pipelines, including a fixed seat. An expansion rod is fixedly installed inside the fixed seat. A centering mechanism is fixedly installed at the upper end of the expansion rod. A guide rod is fixedly installed on the lower surface of the centering mechanism. The lower end of the guide rod is slidably connected to the upper end of the fixed seat. A fixed clamp seat is fixedly installed at the upper end of the centering mechanism. A connecting convex edge is rotatably installed at the upper end of the fixed clamp seat. The connecting convex edge is detachably connected to the fixed clamp seat by bolts. An installation frame is fixedly installed at the upper end of the connecting convex edge. A second lead screw is rotatably installed inside the installation frame. A movable clamp seat is threadedly sleeved on the outer side of the second lead screw.

[0006] Preferably, the centering mechanism includes a connecting shell. A first lead screw is rotatably installed inside the connecting shell. A linkage block is threadedly sleeved on the outer side of the first lead screw. The upper end of the linkage block is fixedly connected to the bottom of the fixed clamp seat.

[0007] Preferably, the first lead screw is a bidirectional lead screw and is horizontally arranged. A pair of linkage blocks are provided and are respectively matched with the two ends of the first lead screw with opposite threaded rotation directions.

[0008] Preferably, a receiving cavity is opened inside the fixed clamp seat. An elastic member is fixedly installed inside the receiving cavity. A clamping block is fixedly installed at the end of the elastic member. The end of the clamping block close to the elastic member is slidably arranged inside the receiving cavity, and the end away from the elastic member extends to the outside of the fixed clamp seat.

[0009] Preferably, a convex strip is fixedly installed on the outer end surface of the clamping block, and an anti-slip strip is fixedly installed at the tip of the convex strip away from the clamping block.

[0010] Preferably, anti-slip pads are fixedly installed on the surfaces of the fixed clamping seat and the movable clamping seat.

[0011] Preferably, the length direction of the second lead screw is vertically arranged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Example 1: Refer to Figures 1-4, a chemical pipeline installation support structure, including a fixed seat 1, the bottom of the fixed seat 1 is fixedly connected to the tunnel by bolts, and the entire support structure is supported and fixed by the fixed seat 1. A telescopic rod 3 is fixedly installed inside the fixed seat 1, and a centering mechanism is fixedly installed at the upper end of the telescopic rod 3. The telescopic rod 3 can drive the centering mechanism to move up and down. A guide rod 2 is fixedly installed on the lower surface of the centering mechanism, and the lower end of the guide rod 2 is slidably connected to the upper end of the fixed seat 1. During the up and down movement of the centering mechanism, the guide rod 2 can play a role of supporting and guiding to ensure the stable up and down movement of the centering mechanism.

[0020] A fixed clamp seat 7 is fixedly installed at the upper end of the centering mechanism. There are a pair of fixed clamp seats 7. A connecting convex edge 10 is rotatably installed at the upper end of the fixed clamp seat 7. The connecting convex edge 10 is detachably connected to the fixed clamp seat 7 by bolts. An installation frame 9 is fixedly installed at the upper end of the connecting convex edge 10. The installation frame 9 can rotate around the fixed clamp seat 7 through the connecting convex edge 10. A second lead screw 11 is rotatably installed inside the installation frame 9. The length direction of the second lead screw 11 is vertically arranged. The end of the second lead screw 11 is provided with a rotating handle or a motor. The second lead screw 11 can be driven to rotate by manually rotating the handle, and the second lead screw 11 can be driven to rotate by the motor itself. A movable clamp seat 12 is sleeved on the outer side of the second lead screw 11 with threads. The rotation of the second lead screw 11 can drive the movable clamp seat 12 to move up and down, so that the distance between the fixed clamp seat 7 and the movable clamp seat 12 can be adjusted, and pipes with different diameters can be clamped. Anti-slip pads 8 are fixedly installed on the surfaces of the fixed clamp seat 7 and the movable clamp seat 12. The anti-slip pads 8 have a good anti-slip effect, and can improve the stability of the cooperation between the pipe and the clamp seat through the anti-slip pads 8.

[0021] The installation frame 9 has two working states. One is in the vertical state, as shown in the appendix Figure 1 . At this time, the movable clamp seat 12 is located above the fixed clamp seat 7. The other is in the horizontal state. At this time, the installation frame 9 and the movable clamp seat 12 are turned outwards. At this time, there is no obstruction above the fixed clamp seat 7, and the pipe can be conveniently placed on the fixed clamp seat 7. Then, by turning the installation frame 9 and the movable clamp seat 12 into the vertical state, the pipe can be clamped and fixed.

[0022] The centering mechanism includes a connecting shell 4. Inside the connecting shell 4, a first lead screw 5 is rotatably installed. The first lead screw 5 is a bidirectional lead screw and is horizontally arranged. The end of the first lead screw 5 is fixedly connected to an external motor. The first lead screw 5 can be driven to rotate by the external motor. A linkage block 6 is sleeved on the outer side of the first lead screw 5 in a threaded manner. When the first lead screw 5 rotates, it can drive the linkage block 6 to move. The upper end of the linkage block 6 is fixedly connected to the bottom of the fixed clamp seat 7. There are a pair of linkage blocks 6 which are respectively matched with the two ends of the first lead screw 5 with opposite threaded rotation directions. When the first lead screw 5 rotates, the two linkage blocks 6 will approach each other or move away from each other simultaneously. The movement of the linkage block 6 will drive the fixed clamp seat 7 to approach or move away simultaneously, and can clamp and fix pipes with different diameters.

[0023] An accommodation cavity 13 is formed inside the fixed clamp seat 7. An elastic member 14 is fixedly installed inside the accommodation cavity 13. The end of the elastic member 14 is fixedly installed with a clamping block 15. The end of the clamping block 15 close to the elastic member 14 is slidably arranged inside the accommodation cavity 13, and the end far from the elastic member 14 extends to the outside of the fixed clamp seat 7. The angle of the clamping block 15 is inclined. A convex strip 16 is fixedly installed on the outer surface of the outer end of the clamping block 15. There are multiple convex strips 16 arranged evenly. An anti-slip strip 17 is fixedly installed at the end of the convex strip 16 far from the tip of the clamping block 15. When the pipe is clamped between the fixed clamp seat 7 and the movable clamp seat 12, the pipe will squeeze the convex strip 16 and the clamping block 15, and the clamping block 15 will squeeze the elastic member 14. When the elastic member 14 is squeezed, it will provide an elastic supporting force to the pipe through the clamping block 15. When the pipe is in tight contact with the fixed clamp seat 7, the elastic member 14 is squeezed, the surface of the pipe is in contact with the convex strip 16, and the anti-slip strip 17 can increase the magnitude of the friction force between the pipe and the convex strip 16, making it difficult for the pipe to rotate around its central axis after being fixed, and can further avoid the stability of the cooperation between the pipe and the clamp seat.

[0024] Working principle: When installing the chemical pipeline installation support structure, first install and fix the fixed seat 1 at the specified position. Open the installation frame 9 outward so that there is no obstruction above the fixed clamping seat 7. Place the pipeline between the fixed clamping seats 7. Rotate the installation frame 9 upward and fix the connecting convex edge 10 with bolts. Then drive the first lead screw 5 to rotate. The rotation of the first lead screw 5 will drive the fixed clamping seats 7 to approach each other simultaneously through the linkage block 6. The approach of the fixed clamping seats 7 will also drive the movable clamping seats 12 to approach each other simultaneously. Then drive the second lead screw 11 to rotate. The rotation of the second lead screw 11 will drive the movable clamping seats 12 to move downward, so that the pipeline can be clamped by the fixed clamping seats 7 and the movable clamping seats 12, clamping and fixing the pipeline from different angles. It can not only clamp pipelines with different diameters, but also prevent the pipeline from shifting, and the effect of clamping and restricting is significantly improved. At this time, the pipeline tightly abuts against the fixed clamping seat 7. The anti-slip pad 8 can prevent the pipeline from sliding between the pipeline and the fixed clamping seat 7. The convex strips 16 and the anti-slip strips 17 can tightly abut against the pipeline under the elastic support of the elastic member 14, and can further prevent the pipeline from sliding between the pipeline and the fixed clamping seat 7. At this time, the fixation of the pipeline is completed, and the stability of the pipeline fixation is significantly improved. Finally, the height of the pipeline can be adjusted through the telescopic rod 3, and the installation work of the pipeline can be completed.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
