Description

Technical Field

[0001] This utility model relates to the field of pipeline trenches, specifically a pipeline trench support structure. Background Technology

[0002] When laying and installing pipelines in current building or municipal engineering projects, trenches are usually dug according to the required size of the pipelines to be laid, and then the pipelines are fixedly installed in the trenches. When carrying out pipeline installation in the trenches, trench support structures are needed to support the trenches to ensure stability during construction.

[0003] A search revealed an existing patent (publication number: 202421166140.1) that discloses a pipeline trench support structure, comprising: a first retaining steel plate and a second retaining steel plate disposed on the two side walls of the trench; a first vertical steel pipe disposed at the inner first end of the first retaining steel plate; a second vertical steel pipe disposed between the inner first end and the inner second end of the first retaining steel plate; and a third vertical steel pipe disposed at the inner first end of the second retaining steel plate. While this patented technology solves the problems of inconvenient mechanical operation and uneconomical traditional support structures, it still has limitations in application, including difficulty in adjusting the angle of the support plates during use, inability to adapt to trenches with sloping sides, and a relatively tight connection between the support plates and the support mechanism, making it inconvenient to quickly separate and disassemble the device during transportation, thus reducing the space occupied during transport and the inconvenience of handling the device.

[0004] Therefore, those skilled in the art have provided a pipeline trench support structure to solve the problems mentioned in the background art.

[0005] Practical content

[0006] 1. Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this application provides a pipeline trench support structure that solves the problems of inconvenient adjustment of the support mechanism angle, inapplicability to trenches with sloping sides, and tight connection between the support plate and the support mechanism, which prevents quick disassembly for easy transportation and handling.

[0008] 2. Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A pipe trench support structure includes a positioning shell and two support plates. A bidirectional threaded rod is rotatably connected between the inner walls of one of the two sides of the positioning shell. A worm gear is fixedly connected to the outer side of the bidirectional threaded rod. A worm is rotatably connected between the inner walls of the other two sides of the positioning shell. A movable frame is threadedly connected to the outer side of both ends of the bidirectional threaded rod. A support rod is slidably connected to the outer side of the movable frame. An elastic telescopic rod is provided at the bottom of the support rod. Several first positioning holes are opened inside the movable frame. Several second positioning holes are opened inside the elastic telescopic rod. A push block is fixedly connected to one end of the elastic telescopic rod. An anti-slip groove is opened on the side of the support plate away from the positioning shell.

[0011] With the above technical solution, the distance between the two support plates can be adjusted arbitrarily during use to adapt to trenches of different widths. The angle of the support plates can also be adjusted according to the slope of the trench to fit the slope. This solves the problem that the angle of the support mechanism is not easy to adjust and cannot be used in trenches with sloping sides, which leads to a large limitation in the use of the device.

[0012] Furthermore, the worm gear meshes with a worm wheel, and a throttle handle is rotatably connected to the side of the positioning housing, with the throttle handle fixedly connected to the worm gear;

[0013] With the above technical solution, the throttle allows the user to easily drive the worm gear to rotate, thereby causing the worm gear to rotate. When the user releases the throttle, the worm gear can restrict the worm gear, making the worm gear self-locking.

[0014] Furthermore, the movable frame is L-shaped, and several first positioning holes are evenly distributed inside the movable frame. The support rod has a through hole that matches the size of the first positioning hole and is movably connected to a first pin.

[0015] Through the above technical solution, the support rod can slide on the outside of the mobile frame to adjust the distance between the two support rods, thereby supporting trenches of different widths. The first pin 14 can enter the interior of the support rod and connect the support rod to the mobile frame 8 through the first positioning hole, thereby limiting the position of the support rod.

[0016] Furthermore, a fixed block is fixedly connected to the bottom of the support rod near the movable frame, a rotating block is rotatably connected inside the fixed block, and an elastic telescopic rod is fixedly connected to the side of the rotating block away from the fixed block;

[0017] Through the above technical solution, the rotating block can drive the elastic telescopic rod to rotate. When rotating, the elastic telescopic rod can adjust its own length so that it can contact and support the support plate at different angles.

[0018] Furthermore, several second positioning holes are evenly distributed inside the end of the elastic telescopic rod away from the rotating block, and the end of the elastic telescopic rod near the rotating block has a through hole that matches the size of the second positioning hole and is movably connected to a second pin.

[0019] Through the above technical solution, the second pin can limit the length of the elastic telescopic rod, so that the length of the elastic telescopic rod cannot be changed after it comes into contact with the support plate, thereby limiting the elastic telescopic rod and ensuring that the elastic telescopic rod always supports the support plate.

[0020] Furthermore, two first limiting blocks are fixedly connected to the side of the support plate, and first push rods are fixedly connected to both sides of the end of the support rod away from the moving frame.

[0021] Through the above technical solution, the first push rod can enter the interior of the first limiting block, thereby pushing the first limiting block and supporting the support plate.

[0022] Furthermore, two second limiting blocks are fixedly connected to the side of the support plate, and second push rods are fixedly connected to both sides of the push block;

[0023] Through the above technical solution, the second push rod can enter the interior of the second limiting block, thereby pushing the second limiting block and supporting the support plate.

[0024] Furthermore, the first limiting block has a groove inside that matches the first push rod, and the second limiting block has a groove inside that matches the second push rod.

[0025] Through the above technical solution, the internal grooves of the first limiting block and the second limiting block can better accommodate the first push rod and the second push rod, preventing the first push rod and the second push rod from changing position when pushing the first limiting block and the second limiting block.

[0026] 3. Beneficial effects

[0027] This utility model provides a pipeline trench support structure. It has the following beneficial effects:

[0028] 1. This utility model provides a pipeline trench support structure. Through the arrangement of a bidirectional threaded rod, worm gear, worm, push block, support rod, rotating block, elastic telescopic rod, first limiting block, second limiting block, first push rod, and second push rod, the distance between the two support plates can be adjusted arbitrarily during use to adapt to trenches of different widths. Moreover, the angle of the support plates can be adjusted according to the slope of the trench to fit the slope of the trench. This solves the problem that the angle of the support mechanism is not easy to adjust and cannot be used in trenches with inclined slopes, resulting in a large limitation in the use of the device.

[0029] 2. This utility model provides a pipeline trench support structure. Through the arrangement of a first limiting block, a second limiting block, a first push rod, a second push rod, an elastic telescopic rod, and a support rod, the device allows for easy separation during use by simply adjusting the length of the support mechanism to remove its support from the support plate. This separation enables adjustment of the overall length of the support mechanism, reducing its footprint. It solves the problem of tight connections between the support plate and the support mechanism, which hinders quick separation and disassembly during transport, thus reducing the space occupied during transport and the inconvenience of handling the device.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific implementation method 1:

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This embodiment of a pipe trench support structure includes a positioning shell 1 and two support plates 2. A bidirectional threaded rod 3 is rotatably connected between the inner walls of two sides of the positioning shell 1. A worm gear 4 is fixedly connected to the outer side of the bidirectional threaded rod 3. A worm 5 is rotatably connected between the inner walls of the other two sides of the positioning shell 1. A movable frame 8 is threadedly connected to the outer sides of both ends of the bidirectional threaded rod 3. A support rod 9 is slidably connected to the outer side of the movable frame 8. An elastic telescopic rod 12 is provided at the bottom of the support rod 9. Several first positioning holes 13 are opened inside the movable frame 8. Several second positioning holes 15 are opened inside the elastic telescopic rod 12. A push block 7 is fixedly connected to one end of the elastic telescopic rod 12. An anti-slip groove 21 is opened on the side of the support plate 2 away from the positioning shell 1. The worm gear 5 meshes with the worm gear 4. A handle 6 is rotatably connected to the side of the shell 1. The handle 6 is fixedly connected to the worm gear 5. The movable frame 8 is L-shaped. Several first positioning holes 13 are evenly distributed inside the movable frame 8. The support rod 9 has a through hole that matches the size of the first positioning hole 13 and is movably connected to a first pin 14. A fixing block 10 is fixedly connected to the bottom of the support rod 9 near the movable frame 8. A rotating block 11 is rotatably connected inside the fixing block 10. An elastic telescopic rod 12 is fixedly connected to the side of the rotating block 11 away from the fixing block 10. Several second positioning holes 15 are evenly distributed inside the side of the elastic telescopic rod 12 away from the rotating block 11. A through hole that matches the size of the second positioning hole 15 is opened inside the side of the elastic telescopic rod 12 near the rotating block 11 and is movably connected to a second pin 16. Specific implementation method 2:

[0040] Please see Figure 5 In this embodiment, a pipe trench support structure is provided, wherein two first limiting blocks 17 are fixedly connected to the side of the support plate 2, and two first push rods 18 are fixedly connected to both sides of the end of the support rod 9 away from the moving frame 8. Two second limiting blocks 19 are fixedly connected to the side of the support plate 2, and two second push rods 20 are fixedly connected to both sides of the push block 7. The first limiting block 17 has a groove inside that matches the first push rod 18, and the second limiting block 19 has a groove inside that matches the second push rod 20.

[0041] In this embodiment, a pipe trench support structure is described. The arrangement of the bidirectional threaded rod 3, worm gear 4, worm 5, push block 7, support rod 9, rotating block 11, elastic telescopic rod 12, first limiting block 17, second limiting block 19, first push rod 18, and second push rod 20 allows for arbitrary adjustment of the distance between the two support plates 2 during use, adapting to trenches of different widths. Furthermore, the angle of the support plates 2 can be adjusted according to the slope of the trench, conforming to the slope. This solves the problem of the support mechanism's angle being difficult to adjust, making it unsuitable for trenches with sloping sides, thus limiting the device's applicability. The major problem is solved by the arrangement of the first limiting block 17, the second limiting block 19, the first push rod 18, the second push rod 20, the elastic telescopic rod 12, and the support rod 9. This allows the device to be used by simply adjusting the length of the support mechanism to remove the support of the support plate 2, thereby separating the two. After separation, the overall length of the support mechanism can be adjusted, reducing the space occupied by the support mechanism. This solves the problem that the connection between the support plate and the support mechanism is relatively tight, making it inconvenient to quickly separate and disassemble the device during transportation. It also reduces the space occupied by the device during transportation and the inconvenience of handling the device.

[0042] The working principle of the above embodiment is as follows: In use, first place the two support plates 2 inside the trench. During placement, the support plates 2 are always in contact with the inner wall of the trench. When the trench is vertical, the support plates 2 are vertical. When the trench is inclined, the support plates 2 become inclined. Then, the user moves the positioning shell 1 and places it between the two support plates 2. Then, pull the support rod 9 to make the support rod 9 slide on the outside of the moving frame 8, so that the first push rod 18 on the side of the support rod 9 enters the interior of the first limiting block 17. Then, rotate the elastic telescopic rod 12 by rotating the rotating block 11. When rotating, the elastic telescopic rod 12 extends and retracts, so that the second push rod 20 on the side of the push block 7 enters the interior of the second limiting block 19. Then, pick up the first pin 14 and place the first pin 14 in the through hole of the support rod 9 and in the corresponding first positioning hole 13, thereby fixing the position of the support rod 9. Then, turn the handle. 6. Rotate the worm gear 5. After the worm gear 5 rotates, the worm wheel 4 drives the double-threaded rod 3 to rotate. After the double-threaded rod 3 rotates, the moving frame 8 drives the support rod 9 to move. Then the support rod 9 pushes the support plate 2 to move, so that the support plate 2 fits tightly with the groove. When the support rod 9 moves, the elastic telescopic rod 12 rotates and extends and retracts, and the second push rod 20 and the second limit block 19 are always in contact. Then pick up the second pin 16 and place the second pin 16 in the internal through hole of the elastic telescopic rod 12 and in the corresponding second positioning hole 15, so as to fix the length of the elastic telescopic rod 12 and determine the rotation angle of the support plate 2. When it is necessary to disassemble and transport the device, pull out the first pin 14 and the second pin 16, then wrap the support rod 9 around the moving frame 8, pull out the elastic telescopic rod 12 and retract it, so that the support mechanism can be separated from the support plate 2.
