Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a transverse movement system and a transverse movement method of a bridge erection machine in mountainous areas. Background Art

[0002] During the construction of a bridge, a bridge erection machine is used to place the prefabricated beams onto the prefabricated bridge piers. A bridge erection machine is a crane, and its main function is to lift the beams, transport them to the location, and then lower them.

[0003] The bridge erection machine is very different from the general crane. It requires harsh conditions and needs to travel on the beams for longitudinal or transverse movement. The bridge erection machine is divided into several types, such as highway bridges, conventional railway bridges, and passenger railway bridges.

[0004] When constructing in mountainous areas, it is often necessary to build a bridge between the tunnel and the pier. Figure 1 , including a first tunnel, a second tunnel and a plurality of bridge piers, the first tunnel and the second tunnel are arranged in parallel, the first tunnel and the second tunnel have a first extension section and a second extension section respectively, and the bridge erecting machine is used to build a bridge between the first tunnel or the second tunnel and the bridge piers. During construction, after the bridge erecting machine passes through the first tunnel and reaches the first extension section through its own longitudinal movement system, it first builds a bridge outside the first tunnel. When the beams on the bridge piers outside the first tunnel are all erected, it is necessary to erect the bridge piers outside the second tunnel. However, at this time, since beams have been erected on the bridge piers outside the first tunnel, the height of the beams is higher than the height of the bridge piers outside the second tunnel, resulting in the bridge erecting machine's transverse movement system being unable to directly transfer the bridge erecting machine to the outside of the second tunnel. However, if it returns from the first tunnel and then passes through the second tunnel, it will take a long time, and the bridge erecting machine will occupy the first tunnel, affecting the subsequent construction of the beams outside the first tunnel, further reducing the construction efficiency. Summary of the invention

[0016] Through the above technical solution, the bottom surface of the top plate cooperates with the inclined conical surface, which facilitates improving the fit between the first flange and the jacket and improving the stability of clamping.

[0031] Embodiment 1 A mountain bridge erection machine transverse movement system, reference Figure 2 and Figure 3 , including a scaffolding support module 1 and a temporary support module 2. The scaffolding support module 1 is arranged on the ground and is located between the pier 5 and the second extension section 41. The temporary support module 2 is detachably connected to the top of the scaffolding support module 1, and multiple temporary support modules are arranged in the transverse direction. The temporary support module 2 is at the same height as the beam piece erected outside the first tunnel 3, and the temporary support module 2 and the beam piece are detachably connected by steel plates and bolts, thereby improving the reliability between the temporary support module 2 and the beam piece. The bridge erecting machine's transverse movement module is installed on the temporary support module 2 corresponding to the guide rail, and the bridge erecting machine's transverse movement module moves on the beam piece and the temporary support module 2 through the guide rail, so that the bridge erecting machine moves to above the pier 5 outside the second tunnel 4. During operation, by assembling the temporary support module 2 and the scaffolding support module 1 between the pier 5 and the second extension section 41, the bridge-building machine can be directly moved to the top of the pier 5 outside the second tunnel 4, so that the bridge-building machine does not need to pass through the first tunnel 3 and the second tunnel 4, which greatly saves time. At the same time, during the transfer of the bridge-building machine, the first tunnel 3 and the second tunnel 4 can be used as transportation channels to transport materials required for construction, further improving the overall construction efficiency.

[0032] Specifically, the top surface of the scaffolding support module 1 is lower than the bottom surface of the pier 5, so that the erection of the beam is not affected after the temporary support module 2 is disassembled.

[0033] The temporary support module 2 includes a support plate 21 and four support legs 22 fixedly connected to the bottom of the support plate 21. A docking leg 11 corresponding to the support leg 22 is fixedly connected to the scaffold support module 1. The support leg 22 and the docking leg 11 are detachably connected through a connection assembly 23. The support leg 22 and the docking leg 11 are detachably connected through the connection assembly 23, which facilitates the detachable connection between the temporary support module 2 and the scaffold support module 1. The scaffold support module 1 can be spliced ​​by a disc-type scaffold.

[0034] Specifically, the connection assembly 23 includes a first flange 231, a second flange 232, a jacket 233 and a compression sleeve. The first flange 231 is fixedly connected to the support leg 22, the second flange 232 is fixedly connected to the docking leg 11, the first flange 231 and the second flange 232 are in contact with each other, the jacket 233 is hinged on the docking leg 11, and two jackets 233 are arranged on each docking leg 11 along its own axis. The jacket 233 can be simultaneously covered on the first flange 231 and the second flange 232 by flipping to clamp the first flange 231 and the second flange 232. The compression sleeve is threadedly connected to the support leg 22, and the bottom surface of the compression sleeve is in contact with the top surface of the jacket 233. The first flange 231 and the second flange 232 are clamped by the jacket 233, and then the jacket 233 is compressed by the compression sleeve, thereby fixing the first flange 231 and the second flange 232, and finally fixing the temporary support module 2 and the scaffold support module 1.

[0035] More specifically, the jacket 233 includes a bottom plate 2331, a side plate 2332 and a top plate 2333 which are connected to each other. The bottom plate 2331 is hinged to the docking leg 11, the side plate 2332 contacts the side walls of the first flange 231 and the second flange 232, and the bottom surface of the top plate 2333 abuts against the top surface of the first flange 231. The top surface of the first flange 231 is an inclined conical surface 2312, the height of which gradually decreases from the center to the edge of the first flange 231, and the bottom surface of the top plate 2333 matches the inclined conical surface 2312. The bottom surface of the top plate 2333 matches the inclined conical surface 2312, which facilitates the improvement of the fit between the first flange 231 and the jacket 233, improves the stability of clamping, and also reduces the possibility of interference between the jacket 233 and the first flange 231 when the jacket 233 is turned over.

[0036] The clamping sleeve includes a spiral seat and a rotating ring 234, the rotating ring 234 is rotatably connected to the bottom of the spiral seat, a pressure rod 2341 is passed through the rotating ring 234 along the axial direction of the first flange 231, and a pressure plate 2343 is fixedly connected to the bottom of the pressure rod 2341. A compression spring 2342 is sleeved on the pressure rod 2341, one end of the compression spring 2342 abuts against the top surface of the pressure plate 2343, and the other end abuts against the bottom surface of the rotating ring 234. The pressure plate 2343 presses the jacket 233, and the pressure is provided by the compression spring 2342, thereby improving the stability of the clamping force on the jacket 233. The spiral seat includes an integrally formed threaded plate 2341 and a side sleeve 2342. The threaded plate 2341 is threadedly connected to the support leg 22, and the side sleeve 2342 is rotatably connected to the rotating ring 234. When the sleeve 233 needs to be compressed, the top of the pressure rod 2341 abuts against the threaded plate 2341, thereby compressing the sleeve 233; when the sleeve 233 needs to be loosened, the threaded plate 2341 moves up, the compression spring 2342 stretches, and the pressure rod 2341 and the threaded plate 2341 are no longer in contact.

[0037] When it is necessary to compress the sleeve 233, the pressure rod 2341 abuts against the spiral plate to compress the sleeve 233. When it is necessary to loosen the sleeve 233, the spiral seat moves upward so that the pressure rod 2341 is no longer in contact with the spiral plate. At this time, the sleeve 233 is compressed by the elastic force of the compression spring 2342, and this elastic force can be overcome when the temporary support module 2 moves upward. Before disassembling the temporary support module 2, the compression spring 2342, the pressure plate 2343 and the pressure rod 2341 can be used to ensure that the temporary support module 2 still has a certain stability after the spiral seat moves upward to avoid falling.

[0038] In addition, a ball 235 is embedded in the bottom of the first flange 231, and the ball 235 can rotate in any direction relative to the first flange 231. The bottom of the ball 235 is located in the inner hole of the second flange 232, which is convenient for improving the stability of the docking between the first flange 231 and the second flange 232. A limiting rod is fixedly connected to the top surface of the second flange 232, and a limiting hole 2311 for inserting the limiting rod is provided on the first flange 231. The setting of the ball 235 facilitates the movement of the temporary support module 2 in the second tunnel 4 after it is transferred to the second tunnel 4. The cooperation between the limiting rod and the limiting hole 2311 further improves the reliability of the fixation between the temporary support module 2 and the scaffolding support module 1.

[0039] A connecting block 211 is fixedly connected to the side wall of the support plate 21, and a connecting groove 212 adapted to the connecting block 211 is provided on the side wall of the support plate 21 away from the connecting block 211. The connecting block 211 facilitates improving the reliability of the connection between adjacent support plates 21, and does not affect the separation of adjacent support plates 21 in the vertical direction. The connecting block 211 can be a dovetail block or a T-block.

[0040] A transverse movement method, based on the above-mentioned transverse movement system of the mountain bridge erection machine, comprises the following steps: S1. Build a scaffolding support module 1 between the bridge pier 5 and the second extension section 41, and build a temporary support module 2 on the scaffolding support module 1. When building the temporary support module 2 on the scaffolding support module 1, first dock the first flange 231 and the second flange 232, so that the limit rod is inserted into the limit hole 2311, and the ball 235 is inserted into the inner hole of the second flange 232, and then flip the jacket 233 so that the bottom surface of the top plate 2333 abuts against the inclined conical surface 2312; then rotate the threaded seat 234 so that the pressure plate 2343 abuts against the jacket 233, and the pressure rod 2341 abuts against the threaded plate 2341, and complete the connection of all the first flanges 231 and the second flanges 232, that is, complete the fixation of the temporary support module 2 and the scaffolding support module 1.

[0041] S2. Lay the guide rails of the bridge erecting machine transverse movement module on the scaffolding support module 1, and then move the bridge erecting machine transverse movement module on the guide rails to move the bridge erecting machine to above the bridge pier 5 outside the second tunnel 4.

[0042] S3, the bridge-building machine moves the bridge-building machine's transverse module and guide rails to the second extension section 41 through the bridge-building machine's longitudinal module. At this time, all threaded seats 234 are moved up so that the jacket 233 is no longer compressed. The temporary support module 2 is then transferred to the second tunnel 4 by the bridge-building machine in multiple times. During the transfer, the beams transported to the second tunnel 4 are synchronously erected on the second extension section 41 and the first pier 5. When the beams on the second extension section 41 and the first pier 5 are erected, the temporary support module 2 is also completely transferred to the second tunnel 4. When the bridge-building machine transfers the temporary module, it first lifts the temporary support module 2. At this time, the first flange 231 moves up to overcome the elastic force of the compression spring 2342, so that the jacket 233 is pushed open, and at the same time, the connecting block 211 is separated from the connecting groove 212, and then the temporary support module 2 is moved to the second tunnel 4.

[0043] Working principle: By assembling the temporary support module 2 and the scaffolding support module 1 between the pier 5 and the second extension section 41, the bridge-building machine can be directly moved to the top of the pier 5 outside the second tunnel 4, so that the bridge-building machine does not need to pass through the first tunnel 3 and the second tunnel 4, which greatly saves time. At the same time, during the transfer of the bridge-building machine, the first tunnel 3 and the second tunnel 4 can be used as transportation channels to transport materials required for construction, further improving the overall construction efficiency. The jacket 233 is pressed by the pressure plate 2343, and pressure is provided by the compression spring 2342, thereby improving the stability of the clamping force of the jacket 233; when the jacket 233 needs to be compressed, the pressure rod 2341 abuts against the spiral seat, thereby compressing the jacket 233, and when the jacket 233 needs to be loosened, the spiral seat moves up, so that the pressure rod 2341 and the spiral seat are no longer in contact, and at this time, the jacket 233 is compressed by the elastic force of the compression spring 2342, and this elastic force can be overcome when the temporary support module 2 moves up, and then before disassembling the temporary support module 2, the compression spring 2342, the pressure plate 2343 and the pressure rod 2341 are relied on to ensure that the temporary support module 2 still has a certain stability after the spiral seat moves up, so as to avoid falling.

[0044] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
