Description

Technical Field

[0001] This utility model relates to the field of support devices, and in particular to a support device for the construction of water supply steel pipelines. Background Technology

[0002] Water supply steel pipelines are pipeline systems used to transport drinking water. Primarily made of steel, they are characterized by high strength, corrosion resistance, and long service life. They are commonly used in urban water supply systems, industrial water delivery, and water supply networks for large building complexes. Water supply steel pipelines can withstand high pressure and are suitable for long-distance water transport and laying in complex terrain conditions. Their materials include carbon steel and stainless steel. Depending on the usage environment and the medium being transported, the inner wall of the pipeline may undergo special treatments, such as anti-corrosion coatings or linings, to prevent water pollution and pipeline corrosion. Furthermore, the installation and maintenance of water supply steel pipelines require specialized technology and equipment to ensure their safe and reliable operation, providing a stable water supply service to residential and industrial users.

[0003] In existing technologies, the construction and installation of water supply steel pipelines requires the pre-excavation of trenches on the ground for laying the steel pipelines. Support devices are then installed within these trenches to prevent soil collapse on both sides, thus protecting personnel and the pipelines during installation. However, existing support devices are relatively simple in structure. They consist of support plates placed on both sides of the trench, with crossbeams erected between the plates according to their spacing. While the support plates provide support to the soil on both sides of the trench, the fixed height of the support plates, the fixed length of the crossbeams, and the fixed angle of the support plates during installation make it difficult to flexibly adjust the support device when supporting trenches of varying depths, widths, and lateral inclinations. This not only reduces the effectiveness of trench support during water supply steel pipeline construction but also diminishes the applicability and flexibility of the support device. Utility Model Content

[0004] The main purpose of this utility model is to provide a construction support device for water supply steel pipelines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A construction support device for a water supply steel pipeline includes a trench. The trench contains several support mechanisms, each including a base plate, a support plate, an extension plate, a concave block, a support cylinder, a knob, a screw, and a T-shaped connector. The support plate is movably connected to the top surface of the base plate via rotating rods at both ends of the bottom connecting plate. The extension plate is movably connected inside the support plate. The concave block is fixedly connected to the inner wall of the top rod on the top surface of the extension plate. The knob is movably connected to one end of the support cylinder via a convex ring on one side. The screw is movably connected inside the support cylinder via the knob and passes through the knob. T-shaped connectors are fixedly connected to opposite ends of the support cylinder and the screw, and the T-shaped connectors are movably connected to the concave block via threaded pins and nuts.

[0007] Preferably, the base plate is provided with a set of symmetrical left and right sides, and a number of conical rods are fixedly installed on the bottom surface of the base plate. A set of symmetrical fixing blocks are fixedly installed on the left side of the top surface of the base plate, and a rotation hole is opened on the front wall of the fixing block.

[0008] Preferably, a connecting plate is fixedly installed on the bottom surface of the support plate, and a rotating rod is fixedly installed at both ends of the connecting plate, the rotating rod being movably installed in the rotating hole.

[0009] Preferably, the top surface of the support plate is provided with a telescopic cavity, and the top of the two sides inside the telescopic cavity are respectively fixedly installed with first guide blocks. The extension plate is inserted into the telescopic cavity, and the two side walls of the extension plate are respectively provided with first guide grooves corresponding to the first guide blocks.

[0010] Preferably, a top rod is fixedly installed on the top surface of the extension plate, and a concave block is fixedly installed at the center of the inner side wall of the top rod, with connecting holes respectively opened on both sides of the concave block's inner wall.

[0011] Preferably, a set of symmetrical second guide grooves are provided on the inner wall of the support cylinder, and a convex groove is provided on the right end wall of the support cylinder. A convex ring is fixedly installed on the left side wall of the knob and is movably installed in the convex groove. A screw hole is provided on the side wall of the knob, and the screw is threadedly connected to the screw hole. A set of symmetrical second guide blocks is fixedly installed on the outer wall of the left end of the screw and is movably installed in the second guide groove. T-shaped connectors are fixedly installed on the left end of the support cylinder and the right end of the screw, respectively. A rotating hole corresponding to the connecting hole is provided on the side wall of the transverse part of the T-shaped connector. The threaded pin is inserted into the connecting hole and passes through the rotating hole, and the nut is threadedly connected to the threaded pin.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the support mechanism places the base plate on both sides of the trench, with the tapered rod on the bottom surface of the base plate inserted into the ground inside the trench. This prevents displacement of the base plate during use. Based on the inclination of the trench's side walls, the support plate is pushed outwards. The rotating rods at both ends of the connecting plate on the bottom surface of the support plate rotate within the rotating holes on the front wall of the fixed block, allowing the support plate to flip. Once the support plate flips and tilts to fit tightly against the trench's side walls, the extension plate is pulled out from the telescopic cavity within the support plate using a push rod, according to the trench's depth. The extension plate moves along the first guide block through the first guide groove until it is level with the trench. Then, the T-shaped connector on the left end of the support cylinder is placed in the recess of the left concave block, aligning the rotating hole with the connecting hole. A threaded pin is then passed through the connecting hole and the rotating hole, and finally, a nut is threaded onto the threaded pin. By flipping the support cylinder, the T-shaped connector at the left end of the support cylinder rotates through the rotating hole along the threaded pin until the support cylinder is flipped to a horizontal position. Then, the knob can be turned to move the screw out of the support cylinder through the threaded hole until the T-shaped connector at the right end of the screw is placed in the recess of the concave block on the right side. Finally, it is connected to the concave block by the threaded pin and nut, which can provide lateral support between the support plates and make the support plates press against the two side walls of the trench, preventing the soil on both sides of the trench from collapsing. This achieves the purpose of adjusting the support for trenches of different depths, widths, and lateral inclinations. It not only improves the support effect of the trench during the construction of water supply steel pipelines, but also improves the applicability and flexibility of the support device. At the same time, the overall structure is simple and quick to assemble, easy to dismantle after construction, and easy to reuse. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 - Figure 6 As shown, a water supply steel pipeline construction support device includes a trench 1. The trench 1 is provided with a plurality of support mechanisms 2. Each support mechanism 2 includes a base plate 3, a support plate 7, an extension plate 12, a concave block 15, a support cylinder 17, a knob 20, a screw 23, and a T-shaped connector 25. The support plate 7 is movably connected to the top surface of the base plate 3 through rotating rods 9 at both ends of the bottom connecting plate 8. The extension plate 12 is movably connected to the inside of the support plate 7. The concave block 15 is fixedly connected to the inner side wall of the top rod 14 on the top surface of the extension plate 12. The knob 20 is movably connected to one end of the support cylinder 17 through a convex ring 21 on one side. The screw 23 is movably connected to the support cylinder 17 through the knob 20 and passes through the knob 20. The opposite ends of the support cylinder 17 and the screw 23 are respectively fixedly connected to the T-shaped connector 25. The T-shaped connector 25 is movably connected to the concave block 15 through a threaded pin 27 and a nut 28.

[0023] like Figure 3 and 4 As shown, the base plate 3 is provided with a set of symmetrical left and right sides, and several cone rods 4 are fixedly installed on the bottom surface of the base plate 3. By inserting the cone rods 4 on the bottom surface of the base plate 3 into the ground in the trench 1 and placing the base plate 3 on both sides in the trench 1, the displacement of the base plate 3 during use can be prevented, ensuring the stability of the base plate 3 after it is laid in the trench 1. A set of symmetrical fixing blocks 5 are fixedly installed on the left side of the top surface of the base plate 3, and a rotating hole 6 is opened on the front wall of the fixing block 5. The rotating hole 6 opened on the front wall of the fixing block 5 is used to cooperate with the rotating rod 9 to realize the rotation operation.

[0024] like Figure 3 and 4As shown, a connecting plate 8 is fixedly installed on the bottom surface of the support plate 7, and a rotating rod 9 is fixedly installed on both ends of the connecting plate 8. The rotating rod 9 is movably installed in the rotating hole 6. After the support plate 7 is flipped so that the rotating rods 9 at both ends of the connecting plate 8 on the bottom surface of the support plate 7 rotate in the rotating hole 6, the support plate 7 can be tightly attached to the two sides of the trench 1 according to the inclination of the two sides of the trench 1, so as to achieve the purpose of supporting the trench 1 with different inclinations.

[0025] like Figure 3 and 4 As shown, the top surface of the support plate 7 is provided with a telescopic cavity 10, and the top of the two sides inside the telescopic cavity 10 are respectively fixedly installed with first guide blocks 11. The extension plate 12 is inserted and installed in the telescopic cavity 10, and the two side walls of the extension plate 12 are respectively provided with first guide grooves 13 corresponding to the first guide blocks 11. After the extension plate 12 is pulled upward, it moves out of the telescopic cavity 10 through the first guide grooves 13 on both sides and along the first guide blocks 11, so that the height of the support plate 7 can be adjusted according to the depth of the groove 1.

[0026] like Figure 3 and 4 As shown, a push rod 14 is also fixedly installed on the top surface of the extension plate 12. The push rod 14 facilitates the removal of the extension plate 12 from the telescopic cavity 10. A concave block 15 is fixedly installed at the center of the inner side wall of the push rod 14. Connecting holes 16 are respectively opened on both sides of the inner wall of the concave block 15. The connecting holes 16 opened on the concave block 15 are used to cooperate with the threaded pin 27 to limit the T-shaped connector 25.

[0027] like Figure 3 , Figure 5 and Figure 6As shown, a set of symmetrical second guide grooves 18 are provided on the inner wall of the support cylinder 17, and a protrusion 19 is provided on the right end wall of the support cylinder 17. A protrusion ring 21 is fixedly installed on the left side wall of the knob 20, and the protrusion ring 21 is movably installed in the protrusion 19. A screw hole 22 is provided on the side wall of the knob 20, and the screw 23 is threadedly connected to the screw hole 22. A set of symmetrical second guide blocks 24 are fixedly installed on the outer wall of the left end of the screw 23 and movably installed in the second guide groove 18. T-shaped connectors 25 are fixedly installed on the left end of the support cylinder 17 and the right end of the screw 23, respectively. A rotating hole 26 corresponding to the connecting hole 16 is provided on the side wall of the transverse part of the T-shaped connector 25. A threaded pin 27 is inserted into the connecting hole 16 and passes through the rotating hole 26. The nut 28 is threadedly connected to the threaded pin 27, so that the T-shaped connector 25 at the left end of the support cylinder 17 is placed in the left side recess. After connecting the T-shaped connector 25 to the concave block 15 through the threaded pin 27 and nut 28, the T-shaped connector 25 is rotated through the rotating hole 26 along the threaded pin 27 to flip the support cylinder 17 to a horizontal state. Then, the knob 20 on the right end of the support cylinder 17 is rotated to make the convex ring 21 on the knob 20 rotate in the convex groove 19. Then, through the screw hole 22, the screw 23 can be moved out from the inside of the support cylinder 17 to the outside through the second guide block 24 along the convex groove 19 until the T-shaped connector 25 on the right end of the screw 23 is placed in the concave block 15 on the right side. After connecting the T-shaped connector 25 to the concave block 15 through the threaded pin 27 and nut 28, the knob 20 can be rotated until it can no longer be rotated. Then, the support cylinder 17 and the screw 23 can be used to press the two side support plates 7 against the two side walls of the groove 1 according to the width of the groove 1 for support.

[0028] The specific operation of support mechanism 2 in conjunction with the construction of water supply steel pipeline is as follows:

[0029] After trench 1 is dug on the ground to facilitate the installation of the water supply steel pipeline, the base plate 3 is laid on both sides of the bottom of trench 1, with the cone rod 4 on the bottom surface of the base plate 3 inserted into the ground at the bottom of trench 1. The cone rod 4 is used to prevent displacement of the base plate 3 during use. Next, the support plate 7 is pushed outward according to the inclination of the two side walls of the trench 1. The rotating rods 9 at both ends of the connecting plate 8 on the bottom surface of the support plate 7 will rotate in the rotating holes 6 opened on the front wall of the symmetrical fixing block 5 installed on the top surface of the base plate 3 until the connecting plate 8 flips over and is tightly attached to the inner side wall of the trench 1. Then, the height of the support plate 7 is adjusted according to the depth of the trench 1. The extension plate 12 is pulled out from the telescopic cavity 10 opened on the top surface of the support plate 7 by the top rod 14. 2. Move the first guide block 11 installed in the telescopic cavity 10 through the first guide groove 13 on both sides to extend the height of the support plate 7 by means of the extension plate 12. After the height of the support plate 7 and the extension plate 12 are the same as the depth of the groove 1, place the T-shaped connector 25 at the left end of the support cylinder 17 into the recess of the concave block 15 installed on the inner side wall of the left top rod 14, so that the rotating hole 26 on the side wall of the lateral part of the T-shaped connector 25 is aligned with the connecting hole 16 on both sides of the inner wall of the recess of the concave block 15. After the threaded pin 27 is passed through the connecting hole 16 and the rotating hole 26, the nut 28 is threaded to the threaded pin 27, so that the support cylinder 17 and the concave block 15 are movably connected together. Then, flip the support cylinder 17 to make the support cylinder 17 movably connected to the concave block 15. The T-shaped connector 25 at the left end of the support cylinder 17 rotates along the threaded pin 27 through the rotating hole 26 until the support cylinder 17 is flipped to a horizontal position. Then, the knob 20 located at the right end of the support cylinder 17 is rotated. The convex ring 21 installed on the left side wall of the knob 20 will rotate within the convex groove 19 opened on the right end wall of the support cylinder 17. At the same time, the knob 20 will cause the screw 23 to move out of the support cylinder 17 to the right through the screw hole 22 opened on the side wall. The second guide block 24 on the outer wall of the left end of the screw 23 will slide within the second guide groove 18 opened on the inner wall of the support cylinder 17, which can restrict the rotation of the screw 23 to a linear motion. The knob 20 is continuously rotated until the screw 23 moves and the T-shaped connector 25 at the right end is placed in the corresponding concave block 15 on the right side. After the rotating hole 26 is aligned with the connecting hole 16, the T-shaped connector 25 is connected to the concave block 15 by the threaded pin 27 and nut 28. This allows for the adaptation to trenches 1 of different widths. Finally, the knob 20 is rotated to change the overall length of the support cylinder 17 and screw 23, so that the support cylinder 17 and screw 23 indirectly apply pressure to the support plates 7 on both sides, making them press against the side walls of the trench 1. This prevents the soil on both sides of the trench 1 from collapsing, thus providing support. This allows for easy adjustment of support for trenches of different depths, widths, and lateral inclinations. This not only improves the support effect of the trench 1 during the construction of water supply steel pipelines but also enhances the applicability and flexibility of the support device.The overall structure is simple and quick to assemble, easy to disassemble after construction, and reusable. After the water supply steel pipeline is completed, the support cylinder 17 can be removed from between the support plates 7 by unscrewing the nut 28 and pulling out the threaded pin 27. Then, the bottom plate 3 can be removed from the trench 1 for backfilling.
