Description

Technical Field

[0001] The present invention relates to the technical field of jacking, and specifically to a walking jacking system. Background Art

[0002] With the rapid development of China's infrastructure construction in recent years, many bridges in the form of "steel structures" have been designed and constructed for structures with large bridge spans. During the construction process, it is necessary to adopt a jacking method to transport the steel beam to the designed position.

[0003] In the walking jacking construction of the steel beam, when the front end of the steel beam moves from the pier top of one jacking pier to the pier top of the next jacking pier, a jacking device will be used, and the rear end of the steel beam will be in a suspended state after being separated from the jacking pier.

[0004] However, the existing walking jacking systems have the following deficiencies:

[0005] 1) Traditional jacking systems mostly adopt fixed structures, lacking modular and extensible designs, resulting in limited operation ranges and difficulty in adapting to complex working conditions. Their displacement adjustment relies on manual calibration, and the accuracy is easily affected by operation errors, with low efficiency. The limiting devices are mostly rigid fixed structures and cannot be flexibly adjusted, and are prone to system instability due to external force impacts.

[0006] 2) There is a problem of insufficient stability. The distribution of its support points is uneven or no buffer design is adopted, resulting in concentrated loads during operation and serious component wear. Especially in complex working conditions, it is prone to shaking or deformation, affecting the construction accuracy and safety.

[0007] 3) The output ends of the hydraulic cylinders of traditional jacking systems mostly adopt rigid fixed structures and lack a quick replacement structure. After long-term use, it will cause damage to the top plate and problems such as shaking or eccentric loading during use.

[0008] Therefore, we propose a walking jacking system to solve the problems raised above. Summary of the Invention

The limiting mechanism is linked by the block B and the threaded rod B to achieve precise limiting and quick locking, reduce displacement deviation, and achieve quick disassembly, installation and maintenance. At the same time, the composite adjustment mechanism of the hydraulic cylinder and the threaded rod simplifies the operation process and reduces the intensity of manual intervention.

[0049] The working principle of the whole device is as follows: When in use, first place the main body mechanism 1 in the required position, so that the bottom plate 101 firmly supports the fixing plate 103. And when facing different operation requirements, the splicing and extension mechanism 4 can be assembled. First, pinch the extension plate 401, and align the connecting plate 403 with the clamping block A404 to the connecting groove A405 and the connecting groove B406, and then press it inward, so that the connecting plate 403 and the clamping block A404 slide into the inside of the bottom plate 101 and the sliding rod A102 through the connecting groove A405 and the connecting groove B406. And at this time, pinch the pulling block A413 to align the clamping rod A412 with the clamping groove A410 and press it inward, so that the clamping rod A412 slides into the inside of the side plate A409 through the clamping groove A410 and slides into the inside of the bottom plate 101 through the clamping groove B411, thereby fixing the extension plate 401 on the right side of the bottom plate 101. Then install the sliding mechanism 2 on the main body mechanism 1. First, pinch the handle 209 and pull it backward, so that the rotating block 208 rotates inside the side block 206 through the rotating groove 207. When the handle 209 is completely turned open, the sliding seat 204 can be carried. At this time, the sliding seat 204 can be installed on the tops of the sliding rod B402 and the sliding rod A102 through the sliding groove 205. Then, the mounting block A212 can be completely slid onto the surface of the mounting rod A202 through the mounting groove A213. Then, pinch the turning handle A217 to align the threaded rod A216 with the threaded groove A215 and rotate it. When the threaded rod A216 is completely screwed into the inside of the fixing block A214 through the threaded groove A215, and at this time, the threaded rod A216 is screwed into the inside of the mounting rod A202 through the fixing groove A203, thereby fixing the mounting rod A202 inside the mounting block A212. At this time, tighten the turning handle A217 through the groove A218. And when facing different requirements, it can be continuously extended and spliced through the connecting groove C407 and the connecting groove D408. When the splicing of the extension mechanism 4 is completed, then install the limiting mechanism 5. Pinch the limiting plate 501 to align the clamping block B502 with the connecting groove D408 and press it. When the clamping block B502 completely slides into the inside of the sliding rod B402, and when the bottom block 503 completely slides into the inside of the extension plate 401 and the side plate B504 completely fits on the front and back surfaces of the extension plate 401, then pinch the turning handle B508 to align the threaded rod B507 with the threaded groove B506 and rotate it, so that the threaded rod B507 rotates into the inside of the fixing block B505 through the threaded groove B506. When the threaded rod B507 is completely screwed into the inside of the fixing block B505 and completely screwed into the inside of the extension plate 401 through the fixing groove B510, then tighten the turning handle B508 through the groove B509. Finally, install the bolt into the inside of the convex plate A8 through the through groove A9, and then install it into the inside of the convex plate B13 through the through groove B14, thereby fixing the support block A6, the support pad A7 and the washer A10 at the bottom end of the bottom plate 101.Moreover, the support block B11, the support pad B12, and the washer B15 are fixed to the bottom end of the extension plate 401 to prevent the bottom plate 101 from sliding relative to the extension plate 401 during use. During use, first activate the lifting mechanism 3 to actuate the hydraulic cylinder B301 inside the receiving groove B210. The hydraulic cylinder B301 drives the top plate 304 to slide upward together with the connecting block B302 and the convex block 303. When the anti-slip pad 305 fits against the bottom end of the beam plate and drives the beam plate to slide upward together, the beam plate is lifted. Then, activate the hydraulic cylinder A201 inside the receiving groove A104 to cause the hydraulic cylinder A201 to drive the sliding seat 204 to slide on the top of the main body mechanism 1 through the connecting block A211. At this time, the sliding seat 204 slides on the top of the sliding rod A102 and the sliding rod B402 through the sliding groove 205 to achieve the effect of pushing. And after long-term use, when it is necessary to replace the top plate 304, first pinch the pull block B24 and pull it to the left, causing the clamping rod B22 to drive the soft pad 23 to slide to the left inside the fixing block C20 and the mounting rod B16. At this time, the clamping rod B22 drives the soft pad 23 to slide to the left inside the mounting rod B16 through the fixing groove C17 and slide to the left inside the fixing block C20 through the card slot C21. When the clamping rod B22 drives the soft pad 23 to completely slide out of the inside of the mounting rod B16 and the fixing block C20, it is okay. Then, pinch the top plate 304 and lift it upward, causing the mounting block B18 to slide upward on the surface of the mounting rod B16. At this time, the mounting block B18 slides upward on the surface of the mounting rod B16 through the mounting groove B19. When the mounting block B18 completely slides out of the surface of the mounting rod B16, maintenance and replacement can be carried out.
