Description

Technical Field

[0001] This utility model belongs to the field of pipe jacking construction technology, specifically relating to a detachable track frame used in pipe jacking construction. Background Technology

[0002] Pipe jacking is a pipeline installation technology used in municipal construction that involves no or minimal excavation. During pipe jacking, the first pipe section is placed on a guide rail using a main jacking cylinder according to the designed slope of the pipeline. The first pipe section is then driven to slide along the guide rail and be jacked into the soil. The excavated soil is then removed. After the first pipe section is completely jacked into the soil, the second pipe section is jacked in, thus pushing multiple pipe sections from the working shaft through the soil layer all the way to the receiving shaft, thereby completing the pipeline installation.

[0003] The prior art discloses a track frame for pipe jacking construction, including two guide rails, multiple sleeper beams, and multiple locking components. The two guide rails are arranged in parallel, and the multiple sleeper beams are evenly distributed along the length of the guide rails. The sleeper beams are fixedly connected to the guide rails by the locking components. The sleeper beams are located on the side of the guide rails closest to the ground. The top wall of the sleeper beams has a fitting groove for fitting the guide rails, and the multiple fitting grooves are evenly distributed along the length of the sleeper beams to facilitate adjustment of the distance between the two guide rails. The locking components include locking bolts and nuts. The locking bolts pass through the guide rails and are threadedly connected to the nuts at one end of the sleeper beams.

[0004] Regarding the aforementioned technologies, during pipe jacking construction, locking bolts and nuts are used to fix the sleeper beams and guide rails, and then the pipes are pushed by the track frame. However, when jacking pipes of different sizes, when the pipe size is small, the pipe is prone to contact with the sleeper beams, causing the pipe to deviate on the guide rails and affecting the installation accuracy of the pipes during pipe jacking construction.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model includes two parallel guide rails 1 and a plurality of parallel connecting components 2 arranged between the two guide rails 1. A plurality of support components 3 are evenly arranged on the guide rails 1 along the length direction, and the support components 3 on the two guide rails 1 are symmetrically distributed at the lower part of the connecting components 2.

[0039] The connecting assembly 2 includes a reinforcing crossbar 21 that passes through the guide rail 1 and two adjusting nuts 22 that pass through both ends of the reinforcing crossbar 21. The two adjusting nuts 22 are located on opposite sides of the two guide rails 1, and the adjusting nuts 22 are fixedly connected to the guide rail 1.

[0040] The reinforcing crossbar 21 includes a positive thread section 211 and a negative thread section 212. The positive thread section 211 is threadedly connected to one of the adjusting nuts 22, and the negative thread section 212 is threadedly connected to the other adjusting nut 22.

[0041] The support assembly 3 includes a support rod 31 and a mounting component 32. The support rod 31 is mounted on the guide rail 1 on the side close to the ground via the mounting component 32.

[0042] In actual use,

[0043] It should be noted that the side wall of the adjusting nut 22 is welded to the guide rail 1, and the adjusting nut 22 is threadedly connected to the reinforcing crossbar 21. By rotating the reinforcing crossbar 21, the distance between the two guide rails 1 can be adjusted, which facilitates stable support for pipes of different sizes and specifications.

[0044] In this embodiment, the mounting component 32 includes a mounting block 322, a spring 326, and two snap-fit ​​blocks 324.

[0045] The mounting block 322 has a through groove 323, which is arranged along the length of the reinforcing crossbar 21; both locking blocks 324 are slidably disposed in the through groove 323; the spring 326 is disposed between the two locking blocks 324, and the spring 326 drives the two locking blocks 324 to extend out of the through groove 323.

[0046] The bottom wall of the guide rail 1 is provided with a mounting groove 321 for fitting the mounting block 322, and the groove wall of the mounting groove 321 is provided with a snap-fit ​​groove 325 for snapping the snap-fit ​​block 324.

[0047] In this embodiment, the distance between the two latching blocks 324 and the side away from each other gradually decreases from the side closer to the support rod 31 to the side farther away from the support rod 31.

[0048] In actual use, there are one or more springs 326. The two ends of the springs 326 are connected to two snap-fit ​​blocks 324 respectively. The shape of the snap-fit ​​groove 325 is adapted to the end of the snap-fit ​​block 324 that extends out of the through groove 323.

[0049] It should be noted that the cross-section of the snap-fit ​​block 324 can be a right-angled trapezoid, or the end of the snap-fit ​​block 324 extending out of the through groove 323 can be set in a hemispherical shape.

[0050] In this embodiment, the support rod 31 includes two support parts 311 and an adjustment part 312 hinged between the two support parts 311; one end of the support part 311 is hinged to the bottom wall of the mounting block 322.

[0051] In this embodiment, the adjustment part 312 includes an adjustment section 3122 and two moving sections 3121. The two moving sections 3121 are symmetrically distributed at both ends of the adjustment section 3122, and the threads on the two moving sections 3121 have opposite directions. The moving sections 3121 are threadedly connected to the adjustment section 3122.

[0052] In actual use, by setting the adjustment part 312, the two moving parts 3121 can be driven to move closer or further apart during the rotation of the adjustment section 3122; in addition, the end of the support part 311 away from the guide rail 1 is rotatably connected to the abutment foot 33, so as to increase the contact area between the support part 311 and the ground and reduce the possibility of local sinking during the pipe pushing process.

[0053] In this embodiment, a sleeve 23 is provided at the connection between the positive thread section 211 and the negative thread section 212, and the sleeve 23 is threadedly connected to the positive thread section 211 or the sleeve 23 is threadedly connected to the negative thread section 212.

[0054] In actual use, during the pipe jacking construction process, by rotating the sleeve 23, the sleeve 23 is positioned at the rotatable connection point of the positive thread section 211 and the negative thread section 212, thus achieving a stable connection between the positive thread section 211 and the negative thread section 212. After the pipe jacking construction is completed, the sleeve 23 is rotated in the opposite direction, so that the sleeve 23 is offset from the rotatable connection point of the positive thread section 211 and the negative thread section 212, thereby realizing the folding of the track frame and facilitating the transportation of the track frame.

[0055] In this embodiment, multiple balls 11 are embedded in the two guide rails 1 near the pipe side.

[0056] In actual use, multiple balls 11 are evenly distributed along the length of the guide rail 1, and the balls 11 are rotatably connected to the guide rail 1, which helps to reduce the friction between the pipe and the guide rail 1 during the movement.

[0057] The implementation principle of this utility model is as follows: When performing pipe jacking construction on pipes of different sizes and specifications, the reinforcing crossbar 21 is rotated according to the specific diameter of the pipe. Since the reinforcing crossbar 21 is threadedly connected to the adjusting nut 22, the reinforcing crossbar 21 drives the two adjusting nuts 22 to move closer or further apart along the length direction of the reinforcing crossbar 21. The adjusting nuts 22 drive the guide rails 1 to move closer or further apart, adjusting until the distance between the two guide rails 1 meets the requirements for pipe jacking construction. Then, the mounting block 322 is aligned with the mounting groove 321, and force is applied to the mounting block 322, causing the mounting block 322 to move towards one side of the mounting groove 321. The mounting block 322 drives the locking block 324 and the spring 326 to move. When the locking block 324 contacts the groove wall of the mounting groove 321, the groove wall of the mounting groove 321 moves towards the locking block 324. When the connecting block 324 applies force, it exerts force on the spring 326. When the connecting block 324 moves into the through groove 323, the spring 326 deforms, and the mounting block 322 continues to move. When the connecting block 324 is directly facing the locking groove 325, the spring 326 pushes the connecting block 324 to move towards the locking groove 325 until the connecting block 324 is engaged in the locking groove 325, thus realizing the installation of the mounting block 322. Then, the adjusting section 3122 is rotated, which drives the moving section 3121 to move closer or further apart. The moving section 3121 drives the support part 311 to move, realizing the adjustment of the included angle between two adjacent support parts 311, thereby realizing the adjustment of the distance between the mounting block 322 and the ground, that is, the adjustment of the height of the guide rail 1, and then the track frame is laid.

[0058] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
