Description

Technical Field

[0001] This utility model relates to the field of pipeline trench support, and in particular to a novel support structure for pipeline trench support. Background Technology

[0002] Pipeline trenches are narrow, elongated trenches or tunnels excavated on the ground for the installation or maintenance of underground pipelines such as water supply pipes, drainage pipes, gas pipes, heating pipes, and cable pipes. During the excavation of pipeline trenches, especially when excavating deeper trenches, the equilibrium state of the original soil is disrupted. The soil itself has limited strength, and when the trench depth reaches a certain level, the lateral earth pressure increases. The support structure forms a barrier to prevent soil from sliding into the trench, providing a safe working space for workers to perform pipeline installation, welding, inspection, and other operations within the trench.

[0003] A search revealed that Chinese Patent Publication No. CN219637923U discloses a novel trench slope support structure. By setting up a concave rotating frame and a rotating shaft, the rotating shaft is used to rotate the concave rotating frame. Then, the support cylinder is used to extend the support rod so that the concave connecting frame extends to the connection hole position of the second support profile. Finally, bolts are passed through the fixing screw hole and the connection hole to fix the concave connecting frame, thereby achieving convenient storage and installation of the support structure.

[0004] In the above technical solution, the support structure is stored and installed by setting up a concave rotating frame and a rotating shaft. However, the support structure is difficult to adapt to changes in the trench width. When the front end of the trench is too wide or too narrow compared to the rear end, the support structure is difficult to adjust its angle to match the trench for support, and it is difficult to adapt to changes in the trench, thereby reducing the support effect. Therefore, a new support structure for pipeline trench support is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a novel support structure for pipeline trench support, comprising a maintenance plate 1. Several maintenance plates 1 are arranged in pairs in a mirror image configuration. To expand the support area, the upper and lower maintenance plates 1 in each pair are connected via a slide block 3. The slide block 3 at the bottom is embedded in a track 2 inside the upper maintenance plate 1 and connected and fixed by a positioning bolt 5. Tracks 2 are fixedly connected to the side walls of the maintenance plates 1. Each maintenance plate 1 has two sets of tracks 2 symmetrically arranged. 2. Lifting holes are provided symmetrically to the maintenance plate 1 for easy lifting and transportation. A slide 3 is installed inside the track 2, and the outer wall of the slide 3 is adapted to the inner wall of the track 2. Positioning holes 4 are provided on the surface of the track 2, with several holes arranged symmetrically in pairs on the surface of the track 2. The positions of the positioning holes 4 are used to adjust the position of the slide 3. Positioning bolts 5 are threadedly connected to the inner walls of the positioning holes 4. The inner wall of the slide 3 is threadedly connected to the outer wall of the positioning bolts 5. A support shaft 6 is fixedly connected to the surface of the slide 3, and the outer wall of the support shaft 6 is fixedly connected to... A spherical seat 7 is connected to the ball seat 7. An adjusting steel ball 8 is rotatably connected to the inner wall of the spherical seat 7. One side of the spherical seat 7 is open, allowing the adjusting steel ball 8 to be enclosed within it. The adjusting steel ball 8 can rotate at any angle within the spherical seat 7. A support rod 9 is fixedly connected to the outer wall of the adjusting steel ball 8. An clearance groove 10 is formed on the inner wall of the support rod 9. A double-acting screw 11 is installed inside the clearance groove 10. The clearance groove 10 is fitted onto the outer wall of the double-acting screw 11. A rotating handle 13 is fixedly connected to the center of the double-acting screw 11. The outer wall of the rotating handle 13... A sleeve 12 is rotatably connected. Each set of sleeves 12 is divided into two sections. The handle 13 controls the rotation of the bidirectional lead screw 11. When the handle 13 is turned, it can rotate the bidirectional lead screw 11. In turn, the two sets of mirror-shaped threaded sleeves 14 drive the two sets of support rods 9 to move closer or further away. The sleeve 12 is sleeved on the outer wall of the bidirectional lead screw 11. The inner wall of the sleeve 12 is slidably connected to the threaded sleeve 14. The side wall of the threaded sleeve 14 is fixedly connected to the limit rod 15. The end of the limit rod 15 away from the threaded sleeve 14 is fixedly connected to the outer wall of the support rod 9.

[0034] Reference Figures 4-6The surface of the maintenance plate 1 is provided with an adjustment assembly, which includes a self-locking telescopic rod 16, a positioning frame 17, a through groove 18, a pressing plate 19, a plug rod 20, a spring 21, a connecting plate 22, and a plug hole 23. The fixed end of the self-locking telescopic rod 16 is rotatably connected to the outer wall of the sleeve 12 via a rotating shaft. Each set of sleeves 12 is provided with two sets of self-locking telescopic rods 16 to provide support for the sleeves 12. The movable end of the self-locking telescopic rod 16 is hinged to the positioning frame 17. The side wall of the positioning frame 17 is provided with a through groove 18. The inner wall of the through groove 18 is slidably connected to the pressing plate 19. Each set of positioning frames 17 is provided with two pressing plates 19. The two pressing plates 19 are magnetic and their surfaces are coated with a waterproof coating. The magnetism on opposite sides of the two pressing plates 19 is mutually repulsive. In this configuration, without external force applied to the two extrusion plates 19, the majority of the area of ​​the two pairs of insertion rods 20 remains outside the positioning frame 17. The surface of the extrusion plate 19 is fixedly connected to the insertion rods 20, which penetrate the positioning frame 17. The outer wall of the insertion rods 20 is slidably connected to the inner wall of the positioning frame 17. A spring 21 is fixedly connected to the surface of the extrusion plate 19 and is sleeved on the outer wall of the insertion rods 20. The end of the spring 21 away from the extrusion plate 19 is fixedly connected to the inner wall of the positioning frame 17. A connecting plate 22 is fixedly connected to the side wall of the maintenance plate 1. Several sets of connecting plates 22 are provided and are evenly distributed. Insertion holes 23 are provided through the outer wall of the connecting plate 22 and are evenly distributed on the connecting plate 22.

[0035] Reference Figures 3-5 The inner wall of the sleeve 12 is provided with a guide groove 24, and a guide block 25 is slidably connected to the inner wall of the guide groove 24. Each set of sleeves 12 has four sets of guide grooves 24, which are connected to each set of threaded sleeves 14 through two corresponding guide blocks 25. When the threaded sleeves 14 move, they move horizontally along a predetermined trajectory. The outer wall of the guide block 25 is fixedly connected to the outer wall of the threaded sleeve 14. The outer wall of the sleeve 12 is fixedly connected with a reinforcing rib 26. The reinforcing rib 26 can increase the rigidity and strength of the sleeve 12 and avoid deformation and twisting, thereby ensuring the support force. The end of the sleeve 12 is fixedly connected with a rubber ring 27. The rubber ring 27 can seal the sleeve 12 to a certain extent and reduce the possibility of dust and impurities entering.

[0036] Working principle: Two maintenance plates 1 are hoisted to both sides of the trench through the hoisting holes. Two pairs of sliding blocks 3 are inserted into the rails 2. Positioning bolts 5 are manually screwed into the corresponding positioning holes 4 to fix the sliding blocks 3. A positive rotational force is then applied to the handle 13, causing the double-acting screw 11 to rotate, thus moving the two pairs of threaded sleeves 14 away from each other. Limiting rods 15 keep the two pairs of support rods 9 away from each other, providing lateral support for the distance between the two maintenance plates 1. Simultaneously, two pressing plates 19 are manually pressed towards opposite sides, causing the spring 21 to stretch. Positioning brackets 17 are inserted into the gap between two adjacent connecting plates 22. After the insertion rod 20 aligns with the corresponding insertion hole 23, the pressing plate 19 is manually released, and the insertion rod 20 is fixed inside the insertion hole 23. When the beginning and end of the trench are on the same horizontal line, the two pairs of self-locking telescopic rods 16 and support rods 9 are set parallel to each other. The maintenance plates 1 are then moved according to the above operation method. The first and last ends of plate 1 are horizontally supported. When the width of the trench changes, the handle 13 at the wider or narrower end of the adjacent trench is rotated. The handle 13 controls the spacing of the support rods 9. The adjustable steel ball 8 can rotate inside the spherical seat 7 to adapt to the width change of the trench. After adjusting the length of the self-locking telescopic rod 16, the corresponding insertion hole 23 is selected according to the inclination of the maintenance plate 1 so that the insertion rod 20 can be inserted. When the maintenance plate 1 adapts to the width change of the trench, the two pairs of self-locking telescopic rods 16 are in an inclined state to provide support for the sleeve 12. When the trench is deep, two sets of maintenance plates 1 are added on the lower maintenance plate 1. The lower slide 3 is connected to the positioning hole 4 at the top of the lower part. At this time, the top part of the lower slide 3 can be embedded in the track 2 on the top maintenance plate 1 and connected to the positioning hole 4 through the positioning bolt 5, which expands the support area, ensures the support effect of the pipeline trench, and can adapt to the width change of the trench. The support operation is convenient and the support is stable.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
