Abstract
Description
Technical Field
[0001] This utility model belongs to the field of guiding structure technology, and in particular relates to a guiding structure for pipe jacking construction. Background Technology
[0002] Pipe jacking is the process of using thrust to push sections of pipe through the working pit into the receiving pit, while simultaneously burying the sections of pipe between the two pits.
[0003] After the first section of the pipeline enters the soil layer by thrust, in order to ensure that the second section, and even the subsequent sections of the pipeline pushed in sequence, maintain the same feeding direction as the previous section of the pipeline inserted into the soil layer, the unpushed sections of the pipeline are supported before being pushed in and kept coaxial with the previous section of the pipeline for guidance and advancement. Utility Model Content
[0004] The technical problem to be solved by this utility model is to increase the coaxiality between pipes, so that the un-push-in pipe and the pushed-in pipe remain coaxial, and guide the un-push-in pipe to feed in the direction of the pushed-in pipe.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pipe jacking construction guide structure, including a support plate one, a support plate two, and support columns, wherein the support columns are symmetrically distributed, and the support plate one and the support plate two are fixedly connected to the two ends of the symmetrical support columns. A feed hole is opened at the center of the end face of the support plate one. The structure also includes a guide propulsion mechanism and an adjustable bearing component. The guide propulsion mechanism is sleeved on the outer wall of the symmetrical support columns and slides back and forth between the support plate one and the support plate two along the axial direction of the support columns. The adjustable bearing component is located above the guide propulsion mechanism.
[0006] Furthermore, the guiding and propulsion mechanism includes a moving block, a stud, a rotary motor, and a moving plate. The moving block is slidably disposed on the outer wall of the symmetrical support columns. The moving plate is fixedly connected to the upper part of the moving block near the second support plate. The stud passes through the moving block and is rotatably connected between the first and second support plates. The stud is located between the symmetrical support columns. The rotary motor is installed on the outer wall of the second support plate, and the output end of the rotary motor is connected to one end of the stud.
[0007] Furthermore, the inner wall of the feed hole has sliding openings on both sides, the sliding openings are symmetrically arranged, and the bottom wall of the feed hole has a notch.
[0008] Furthermore, a sliding rod is fixedly connected to the outer wall of the movable plate. The sliding rods are symmetrically arranged, and the end of the sliding rod away from the movable plate is slidably disposed in the support plate through a sliding opening.
[0009] Furthermore, a support roller is rotatably connected between the relatively inner sidewalls of the notch.
[0010] Furthermore, the adjustable bearing assembly includes a vertical plate, a second stud, a second rotary motor, and a bearing block. The vertical plate is fixedly connected to the upper two sides of the movable block, and the vertical plates are symmetrically arranged. The second stud is rotatably connected between the opposite inner sidewalls of the symmetrical vertical plates. The second rotary motor is installed on the outer sidewall of the vertical plate, and the output end of the second rotary motor is connected to one end of the second stud. The bearing block is threadedly connected to the outer sidewall of the second stud, and the bearing block is symmetrically arranged. The bottom wall of the bearing block slides between the symmetrical vertical plates, adhering to the upper wall of the movable block.
[0011] Furthermore, the upper part of the symmetrical bearing block is arranged with opposing inclined surfaces.
[0012] Furthermore, the first stud and the second stud are arranged vertically.
[0013] Furthermore, the bottom walls of the first support plate and the second support plate are fixedly connected with insert plates, and the end face corner of the first support plate is connected with a positioning screw, the fixing direction of the positioning screw being away from the side of the second support plate.
[0014] After adopting the above structure, the beneficial effects of this utility model are as follows: For the guiding connection and pushing between pipes during pipe jacking construction, the two ends of the symmetrical support column are connected to support plate one and support plate two to support the whole device. One end of the pipe is placed on the adjustable bearing component, and the other end is placed on the support roller and located between the symmetrical sliding rods. The height of one end of the pipe is adjusted by the spacing of the symmetrical bearing blocks so that the two ends of the pipe are at the same horizontal line.
[0015] The guide and push mechanism pushes the pipe to one side of the support plate. When the pipe is inserted into the soil, the guide and push mechanism resets and approaches the support plate. The sliding rod retracts synchronously, but the sliding rod does not separate from the two sides of the inserted pipe. When the pipe is pushed in the future, the sliding rods on both sides limit the two sides of the pipe and push it along the feed direction while adhering to the end face of the previous pipe section, so as to realize the guiding and conveying of the pipes connected to each other.

[0022] like Figure 1-4 As shown, a pipe jacking construction guide structure includes a support plate 1, a support plate 2, and support columns 3. The support columns 3 are symmetrically distributed. The support plate 1 and support plate 2 are fixedly connected to both ends of the symmetrical support columns 3. A feed hole 4 is opened at the center of the end face of the support plate 1. The structure also includes a guide propulsion mechanism 5 and an adjustable bearing component 6. The guide propulsion mechanism 5 is sleeved on the outer wall of the symmetrical support columns 3 and slides back and forth between the support plate 1 and support plate 2 along the axial direction of the support columns 3. The adjustable bearing component 6 is located above the guide propulsion mechanism 5 and is used to support one end of the pipe. A notch 7 is opened on the bottom wall of the feed hole 4. A support roller 8 is rotatably connected between the opposite inner walls of the notch 7. The support roller 8 is used to support the other end of the pipe. The pipe is pushed along the feed direction of the feed hole 4 by the guide propulsion mechanism 5.
[0023] like Figure 1 and Figure 4As shown, in order to adjust the feed angle of the pipeline, the pipeline can be moved up and down at one end of the adjustable bearing assembly 6 to make both ends of the pipeline at the same horizontal height. The adjustable bearing assembly 6 includes a vertical plate 15, a second stud 16, a second rotary motor 17, and a bearing block 18. The vertical plate 15 is fixedly connected to the upper two sides of the moving block 9, and the vertical plates 15 are symmetrically arranged. The second stud 16 is rotatably connected between the opposite inner sidewalls of the symmetrical vertical plates 15. The second rotary motor 17 is installed on the outer sidewall of the vertical plate 15, and the output end of the second rotary motor 17 is connected to one end of the second stud 16. The bearing block 18 is threadedly connected to the outer sidewall of the second stud 16, and the bearing blocks 18 are symmetrically arranged. The bottom wall of the bearing block 18 slides between the symmetrical vertical plates 15, adhering to the upper wall of the moving block 9. The upper part of the symmetrical bearing blocks 18 is arranged with opposite inclined surfaces. The symmetrical support blocks are connected by the second stud 16. The connection is 16. The stud 2 16 is a stud with both positive and negative threads and is supported by symmetrical vertical plates 15. The rotating motor 2 17 drives the rotation. The symmetrical bearing blocks 18 move against the upper wall of the moving block 9 and are adjusted in opposite directions. When the rotating motor 2 17 rotates forward, the symmetrical bearing blocks 18 move closer together. The upper inclined surface of the bearing blocks 18 supports both sides of the bottom of the pipe. The height of the pipe is adjusted according to the contact position between the symmetrical bearing blocks 18 and the bottom of the pipe. When the symmetrical bearing blocks 18 are close to each other, the bottom of the pipe contacts the inclined surface of the bearing blocks 18 at a higher position, and the height of the pipe end face is higher. Conversely, when the symmetrical bearing blocks 18 are separated from each other, the bottom of the pipe contacts the inclined surface of the bearing blocks 18 at a lower position, and the height of the pipe end face is also lower. This achieves support for one end of the pipe while adjusting the height of one end of the pipe, so that both ends of the pipe are kept at the same horizontal plane.
[0024] like Figure 1 and Figure 2As shown, to guide and push the pipeline, the guiding and pushing mechanism 5 includes a moving block 9, a stud 10, a rotary motor 11, and a moving plate 12. The moving block 9 is slidably disposed on the outer wall of the symmetrical support columns 3. The moving plate 12 is fixedly connected to the upper part of the moving block 9 near the support plate 2. The stud 10 passes through the moving block 9 and is rotatably connected between the support plate 11 and the support plate 2. The stud 10 is located between the symmetrical support columns 3. The rotary motor 11 is installed on the outer wall of the support plate 2. The output end of the rotary motor 11 is connected to one end of the stud 10. Sliding openings 13 are opened on both sides of the inner wall of the feed hole 4. The sliding openings 13 are symmetrically arranged. A sliding rod 14 is fixedly connected to the outer wall of the moving plate 12. The sliding rod 14 is symmetrically arranged. The end of the sliding rod 14 away from the moving plate 12 is slidably disposed in the support plate 11 through the sliding opening 13. The stud 10... The 0 and stud 16 are arranged vertically. The rotating motor 11 rotates, and the moving block 9 moves along the axial direction of the support column 3 under the limiting action of the stud 10. The moving plate 12 pushes the pipeline towards the feed hole 4 at the rear end of the pipeline. During the movement, the symmetrical sliding rods 14 are located on both sides of the pipeline and are inserted into the soil layer at the same time. After the pipeline section is pushed into the soil layer, the rotating motor 11 reverses, so that the moving block 9 and sliding rods 14 are reset and return to the side close to the support plate 2. However, the sliding rods 14 on both sides of the pipeline are not completely separated from the sides of the pushed pipeline. The opposite side wall near the feed hole 4 is still in contact with the sides of the pipeline. When the subsequent pipeline is lifted and placed on the symmetrical bearing block 18 and support roller 8, the symmetrical sliding rods 14 limit the sides of the pipeline. At the same time, the end faces of the pipeline are in contact, guiding and pushing the subsequent pipeline.
[0025] Among them, the bottom walls of support plate 1 and support plate 2 are fixedly connected with insert plates 19, and the end face corners of support plate 1 are connected with positioning screws 20. The fixing direction of the positioning screws 20 is away from the side of support plate 2. Insert plates 19 are used to increase the connection between support plate 1 and support plate 2 and the ground. After being inserted into the soil, they increase the stability of the device when pushing. At the same time, positioning screws 20 are used to make the end face of support plate 1 fit against the side wall of the working pit.
[0026] In practical use, the device is placed in the working pit, and the bottom insert plates 19 of support plate 1 and support plate 2 are inserted into the soil to increase the supporting force for pushing the pipeline. In the initial state, the guide propulsion mechanism 5 is close to the side of support plate 2. After the pipeline is lifted, one end is placed between the symmetrical bearing blocks 18, and the other end is pushed onto the support roller 8 by the moving plate 12 and located in the feed hole 4. The pipeline is placed stably by its own weight.
[0027] Drive the rotary motor 17 to rotate, adjust the distance between the symmetrical bearing blocks 18, use the inclined surface of the bearing blocks 18 to support the bottom of the pipe, adjust the height of the pipe, and make the height of both ends of the pipe level.
[0028] Drive the rotary motor 11 to rotate, and under the limiting action of the symmetrical support column 3, the stud 10 pushes the moving block 9 to move towards the feed hole 4 side, and uses the moving plate 12 to push the pipe into the soil layer at the rear end of the pipe.
[0029] During the movement, the symmetrical sliding rods 14 are located on both sides of the pipe and are inserted into the soil layer synchronously. After the pipe section is pushed into the soil layer, the rotary motor 11 reverses, causing the moving block 9 and sliding rods 14 to reset and return to the side close to the support plate 2. However, the sliding rods 14 on both sides of the pipe are not completely separated from the sides of the pushed pipe. The opposite side wall near the feed hole 4 is still in contact with the sides of the pipe. When the subsequent pipe is lifted and placed on the symmetrical bearing block 18 and support roller 8, the symmetrical sliding rods 14 are used to limit the sides of the pipe. At the same time, the end faces of the pipes are in contact, guiding and connecting the subsequent pipes.
