Description

Technical Field

[0001] The utility model relates to the technical field of beam-making machines, and particularly relates to a matching tooling for the front inverted U gantry and the inner sliding beam of an inner form of a cantilever beam-making machine. Background Art

[0002] With the booming development of the construction industry in China, great progress has been made in bridge engineering technology. The emergence of intelligent cantilever beam-making machines has greatly met the needs of intelligent construction of high-speed railway projects, significantly improved the automation and intelligence levels of cantilever casting continuous beams, accelerated the construction progress and enhanced construction safety, and successfully overcome many problems such as poor stability of traditional hanging baskets, low intelligence level, high risks in installation and demolition, and difficulties in construction precision control. However, during the construction process of traditional beam-making machines, there are still some technical problems to be solved urgently.

[0003] During the construction of traditional beam-making machines, the process of moving the inner sliding beam of the inner form forward is extremely cumbersome. It is necessary to pull the inner sliding beam of the inner form to a designated position and fix it in advance with a manual hoist, and then rely on a motor or a hydraulic cylinder to move the whole inner form along the inner sliding beam to the next bridge construction position. This operation method is not only complicated in steps, but also during the whole process, the inner sliding beam is very likely to deviate when moving forward. Once deviation occurs, it will not only affect the normal movement of the inner form, but may also cause inaccurate installation position of the inner form, thereby having an adverse impact on the precision and quality of subsequent bridge construction. In addition, during the demolding process after pouring, the bottom platform descends by relying on the front suspension rod, and at this time, the front inverted U gantry will fall together with the suspension rod. Since this process involves the coordinated operation of multiple components and the operation environment is at a high altitude, any malfunction or operation error in any link is extremely likely to cause a safety accident, posing a serious threat to the life safety of construction workers.

[0013] In one possible implementation, the second adjusting component further includes a spring sleeved on the adjusting screw, one end of the spring abutting against the adjusting plate and the other end abutting against the inner sliding beam of the inner mold, so as to provide preload after the adjusting screw is adjusted, thereby enhancing the stability of the connection.

[0014] In one possible implementation, the adjusting plate has a threaded hole adapted to the adjusting screw, the adjusting screw has a length of 100-150mm, and the end of the adjusting screw away from the inner mold slide beam is provided with a hexagonal head for easy rotation.

[0015] In one possible implementation, after the connecting plate and the front U-shaped gantry are connected by the first adjusting assembly, the two are further fixed by at least four fastening bolts, which are evenly distributed along the circumference of the connecting plate.

[0016] In one possible implementation, after the connecting channel steel and the inner sliding beam of the inner mold are connected by the second adjusting component, the two are positioned by at least two positioning pins, and the positioning pins are interference-fitted with the positioning holes on the connecting channel steel and the inner sliding beam of the inner mold.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Figure 1 This illustration shows a schematic diagram of the installation principle structure of the adapter tooling for the front inverted U-shaped gantry and the inner sliding beam of the cantilever beam-making machine provided in an exemplary embodiment of the present invention. Figure 2 This illustration shows a schematic diagram of the adapting tooling for the front inverted U-shaped gantry and the inner sliding beam of the cantilever beam-making machine provided in an exemplary embodiment of the present invention. Figure 3 It shows Figure 2 A schematic diagram of the 1-1 direction structure. Figure 4 It shows Figure 2The 2-2 structural diagram shows that the adapter 1 for the front inverted U-shaped gantry and the inner sliding beam of the cantilever beam-making machine includes: a traction beam 11, which is connected to the front inverted U-shaped gantry 21 of the cantilever beam-making machine 2 via a connecting plate 12, and connected to the inner sliding beam 22 of the inner mold of the cantilever beam-making machine 2 via a connecting channel steel 13, so that the inner sliding beam 22 of the inner mold moves synchronously with the cantilever beam-making machine 2, and stabilizes the front inverted U-shaped gantry 21 during the descent of the bottom platform 23 of the cantilever beam-making machine 2; wherein, a first adjustment component is provided at the connection position between the connecting plate 12 and the front inverted U-shaped gantry 21 to adjust the relative position of the connecting plate 12 and the front inverted U-shaped gantry 21; a second adjustment component is provided at the connection position between the connecting channel steel 13 and the inner sliding beam 22 of the inner mold to adjust the relative position of the connecting channel steel 13 and the inner sliding beam 22 of the inner mold.

[0031] In this embodiment, a rigid connection is established between the inverted U-shaped gantry 21 and the inner sliding beam 22 of the inner mold through the traction beam 11. The connecting plate 12 securely connects the traction beam 11 and the inverted U-shaped gantry 21, while the connecting channel steel 13 achieves rigid fixation between the traction beam 11 and the inner sliding beam 22. In this case, the overall rigid connection ensures that the inner sliding beam 22 moves synchronously with the cantilever beam-making machine 2, avoiding the problem of sliding beam displacement in traditional construction. Furthermore, when the bottom platform 23 descends, the traction beam 11 restricts the pulling of the inverted U-shaped gantry 21, preventing the gantry from falling freely with the boom. In addition, the first adjustment component at the connecting plate 12 can finely adjust the relative position of the gantry and the beam, and the second adjustment component at the connecting channel steel 13 can calibrate the docking accuracy of the sliding beam and the beam. The dual adjustment ensures that the tooling is adaptable to different construction conditions, improving installation accuracy and construction safety.

[0032] In some embodiments, the first adjustment component includes: a slotted hole formed on the connecting plate 12 and a locking bolt adapted to the slotted hole, wherein the relative position of the connecting plate 12 and the front U-shaped gantry 21 can be adjusted by the cooperation between the slotted hole and the locking bolt.

[0033] In other embodiments, the first adjustment component further includes an anti-slip pad disposed between the connecting plate 12 and the front U-shaped gantry 21. The anti-slip pad is made of rubber and has a thickness of 3-5mm to increase the friction between the two and prevent the position from shifting after adjustment.

[0034] Preferably, the length of the waist-shaped hole is 80-120mm, the width of the waist-shaped hole is 2-4mm larger than the diameter of the locking bolt, and the waist-shaped hole is set in the horizontal direction so as to adjust the relative position of the connecting plate 12 and the front U-shaped gantry 21 in the horizontal direction.

[0035] In this embodiment, the oblong hole on the connecting plate 12 provides space for horizontal adjustment. Loosening the locking bolt allows the connecting plate 12 to move relative to the forward U-shaped gantry 21 along the oblong hole direction. After it is in place, tightening the bolt completes the fixation.

[0036] In some embodiments, the second adjustment component includes: an adjustment plate welded to the connecting channel steel 13, and an adjustment screw passing through the adjustment plate. The end of the adjustment screw abuts against the inner sliding beam 22 of the inner mold. The relative position of the connecting channel steel 13 and the inner sliding beam 22 of the inner mold can be adjusted by rotating the adjustment screw.

[0037] In other embodiments, the second adjustment assembly further includes a spring sleeved on the adjustment screw, one end of the spring abutting against the adjustment plate and the other end abutting against the inner sliding beam 22 of the inner mold, so as to provide preload after the adjustment screw is adjusted, thereby enhancing the stability of the connection.

[0038] Preferably, the adjusting plate has a threaded hole adapted to the adjusting screw, the length of the adjusting screw is 100-150mm, and the end of the adjusting screw away from the inner mold inner slide beam 22 is provided with a hexagonal head for easy rotation.

[0039] In this embodiment, the adjusting plate is welded to the connecting channel steel 13, and its threaded hole is adapted to the adjusting screw. When the adjusting screw with the hexagonal head is rotated, the end of the screw abuts against the inner sliding beam 22 of the inner mold, pushing the connecting channel steel 13 and the inner sliding beam 22 of the inner mold to generate relative displacement.

[0040] Furthermore, after the connecting plate 12 and the front inverted U-shaped gantry 21 are connected by the first adjusting component, the two are further fixed by at least 4 fastening bolts. The fastening bolts are evenly distributed around the circumference of the connecting plate 12, and the clamping force is generated by the axial force of the bolts. The even distribution around the circumference ensures the balance of forces and avoids local stress concentration that could lead to loosening of the connection, thus ensuring the stable pulling of the traction beam 11 on the front inverted U-shaped gantry 21.

[0041] Correspondingly, after the connecting channel steel 13 and the inner sliding beam 22 of the inner mold are connected by the second adjusting component, the two are positioned by at least two positioning pins. The positioning pins are interference-fitted with the positioning holes on the connecting channel steel 13 and the inner sliding beam 22 of the inner mold. The interference fit makes the pin and the hole tightly connected, restricting the relative displacement of the two. With the preload of the second adjusting component, it is ensured that the inner sliding beam 22 of the inner mold moves synchronously with the cantilever beam making machine 2 without deviation, thus improving the reliability of construction.

[0042] Next, the working principle of the adapting tooling for the front inverted U-shaped gantry and the inner sliding beam of the cantilever beam-making machine involved in the embodiments of this utility model will be explained.

[0043] First, after placing the traction beam 11 in the preset position, adjust the relative position of the connecting plate 12 and the front U-shaped gantry 21 through the first adjustment component, loosen the locking bolts, and horizontally move the connecting plate 12 along the waist-shaped hole on the connecting plate 12 so that the traction beam 11 is initially aligned with the front U-shaped gantry 21. After it is in place, tighten the bolts, and the rubber anti-slip pads prevent loosening through friction.

[0044] At the same time, the adjusting screw with a hexagonal head on the connecting channel steel 13 is rotated with a tool. By using the fit of the threaded hole of the adjusting plate, the end of the screw pushes against the inner sliding beam 22 of the inner mold, so as to achieve precise alignment between the connecting channel steel 13 and the sliding beam. After the spring is compressed, it generates a continuous preload force.

[0045] Next, the connecting plate 12 and the front U-shaped gantry 21 are fixed for the second time by at least four circumferentially evenly distributed fastening bolts, and the axial force of the bolts forms a uniform clamping force; the connecting channel steel 13 and the inner mold inner slide beam 22 are positioned by at least two positioning pins with interference fit, and the pin holes are tightly connected to restrict relative displacement, forming a rigid connection in conjunction with the spring preload.

[0046] During the construction phase, when the cantilever beam-building machine 2 moves forward, the integrated linkage structure ensures that the inner sliding beam 22 of the inner mold moves synchronously with the cantilever beam-building machine 2, avoiding deviation. After it is in place, the inner sliding beam 22 of the inner mold is driven to fall into place by hydraulic cylinders or motors. When the bottom platform 23 descends, the traction beam 11 pulls the inverted U-shaped gantry 21 through a rigid connection, preventing it from falling freely with the gantry. Then the bridge pouring operation can be carried out. The multiple functions improve the construction accuracy and safety.

[0047] In summary, the adapting fixture for the front inverted U-shaped gantry and the inner sliding beam of the cantilever beam-making machine provided by this technical solution includes a traction crossbeam, which is connected to the front inverted U-shaped gantry of the cantilever beam-making machine via a connecting plate, and connected to the inner sliding beam of the inner mold of the cantilever beam-making machine via a connecting channel steel, so as to enable the inner sliding beam of the inner mold to move synchronously with the cantilever beam-making machine, and to stabilize the front inverted U-shaped gantry during the descent of the bottom platform of the cantilever beam-making machine; wherein, a first adjustment component is provided at the connection position between the connecting plate and the front inverted U-shaped gantry to adjust the relative position of the connecting plate and the front inverted U-shaped gantry; a second adjustment component is provided at the connection position between the connecting channel steel and the inner sliding beam of the inner mold to adjust the relative position of the connecting channel steel and the inner sliding beam of the inner mold. In this case, it can be applied to the forward movement of the inner formwork and inner sliding beam during the construction of the cantilever beam machine. The structure is simple and easy to construct. It realizes the synchronous movement of the inner formwork and inner sliding beam with the cantilever beam machine and the stable forward U-shaped gantry during the descent of the bottom platform. It avoids movement deviation, speeds up the construction progress, improves the efficiency of bridge construction, and shortens the construction period.

[0048] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
