Description
Technical Field
[0001] This invention relates to the field of hydraulic climbing formwork technology for bridge piers, specifically to a hydraulic climbing formwork device for bridge piers. Background Technology
[0002] Hydraulic climbing formwork can use its own hydraulic power unit to lift the entire platform and work area as a whole. It is easy to operate, the climbing process is stable, the linear control is simple, and the construction speed is fast, which can greatly shorten the construction period. The hydraulic climbing formwork mainly consists of four parts: formwork system, embedded part system, support system, and hydraulic system. The hydraulic system includes hydraulic cylinders, power unit and upper and lower reversing box. By switching the upper and lower reversing box, the lifting guide rail or lifting frame can be controlled to achieve mutual climbing between the frame and the guide rail, so that the hydraulic self-climbing formwork can climb steadily upward.
[0003] During the climbing process, wall-mounted brackets and wall-mounted hangers need to be installed at the previous level. Then, hydraulic equipment drives the guide rail to move upward. After the guide rail connects with the wall-mounted brackets and wall-mounted hangers, the wall-mounted brackets and wall-mounted hangers of the next level are removed. However, this setup has the following problems: when the guide rail is not moving upward, the pre-installed wall-mounted brackets and wall-mounted hangers cannot ensure precise vertical alignment between the wall-mounted brackets and the guide rail. If there is any deviation between the wall-mounted brackets and the guide rail, the guide rail will not be able to connect and fix with the wall-mounted brackets, making it difficult to carry out the climbing formwork work. Readjusting the position of the wall-mounted brackets and wall-mounted hangers will be very time-consuming and delay the construction period. Therefore, a hydraulic climbing formwork device for bridge piers is proposed to address the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a hydraulic climbing formwork device for bridge piers to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] As an optional embodiment of the hydraulic climbing formwork device for bridge piers described in this invention, the hydraulic climbing formwork device for bridge piers includes a connecting pier and a climbing guide rail. A wall-mounted bracket module is installed on the side of the connecting pier by screws, and a wall-mounted hanging bracket module for supporting the climbing guide rail is installed at the other end of the wall-mounted bracket module. A climbing guide rail for climbing the frame is provided on the outer side of the wall-mounted hanging bracket module. A positioning module for guiding is installed on the side of the climbing guide rail facing the connecting pier. A connecting body is detachably connected to the other end of the climbing guide rail, and a climbing hydraulic rod is fixedly connected to the other end of the connecting body. The other end of the climbing hydraulic rod is fixedly connected to the hydraulic operating platform.
[0007] During the climbing formwork device's ascent, wall-mounted brackets and wall-mounted hangers need to be installed at the previous level. Then, hydraulic equipment drives the guide rail upwards. After the guide rail connects with the wall-mounted brackets and hangers, the wall-mounted brackets and hangers at the next level are removed. However, this setup has the following problems: Pre-installing the wall-mounted brackets and hangers before the guide rail moves upwards cannot ensure precise vertical alignment between the wall-mounted brackets and the guide rail. If there is any misalignment between the wall-mounted brackets and the guide rail, the guide rail cannot be properly connected and secured to the wall-mounted brackets, hindering the climbing formwork operation. Readjusting the position of the wall-mounted brackets and hangers is extremely time-consuming and delays the construction schedule. This device, however, addresses this issue during the climbing formwork process. During operation, the positioning module is pre-activated. Once the positioning module extends to a certain height, its position is determined by cooperating with the wall-mounted module. The wall-mounted module is then fixed to the pier surface with screws. Next, the wall-mounted bracket module is installed. After the positioning module is reset, the climbing hydraulic rod is activated, which cyclically moves the climbing guide rail upward. One end of the climbing hydraulic rod is fixedly connected to the hydraulic operating platform to drive the climbing guide rail to move upward stably. It also precisely cooperates with the wall-mounted module and the wall-mounted bracket module to achieve the purpose of fixation. This setting avoids misalignment between the wall-mounted module and the climbing guide rail, ensuring accurate installation and meeting the construction schedule.
[0008] As an optional embodiment of the hydraulic climbing formwork device for bridge piers described in this invention, the positioning module includes a fixed frame and a guide screw. The outer side of the fixed frame is fixedly connected to the climbing guide rail. A motor is fixedly connected inside the fixed frame. A rotating shaft is fixedly connected to the end of the motor's main shaft. The other end of the rotating shaft is rotatably connected to the fixed frame. A drive gear is fixedly connected to the outer side of the rotating shaft, and a driven gear meshes with the outer side of the drive gear. A guide screw is helically connected inside the driven gear.
[0009] During the climbing process, the motor is pre-started, which drives the rotating shaft to rotate. The rotating shaft drives the outer drive gear to rotate, which in turn drives the outer driven gear to rotate. This causes the inner guide screw to move upward. Once the guide screw has moved upward to a certain position, the wall mount module is engaged with it to determine the installation position of the wall mount module. This ensures that the climbing guide rail is aligned with the wall mount module and the wall mount bracket module when it moves upward, facilitating the installation of the climbing guide rail and saving time wasted due to misalignment between the wall mount module and the climbing guide rail.
[0010] As an optional embodiment of the hydraulic climbing formwork device for bridge piers described in this invention, the outer side of the guide screw is also spirally connected to a threaded ring, and the outer side of the threaded ring is fixedly connected to the climbing guide rail.
[0011] To ensure the guide screw moves steadily upward and prevents it from tilting, a threaded ring is provided. The threaded ring cooperates with the driven gear to ensure that the guide screw is in a vertical state, which is used to ensure subsequent positioning.
[0012] As an optional embodiment of the hydraulic climbing formwork device for bridge piers described in this invention, the bottom of the guide screw is fixedly connected to a limiting block, and the limiting block is arranged in the form of a rectangular plate, with one side of the limiting block being slidably connected to the climbing guide rail.
[0013] When the guide screw moves upward, in order to prevent the driven gear from driving the guide screw to rotate, a limit block is installed at the bottom of the guide screw, and the outer side of the limit block is slidably connected to the climbing guide rail. This is used to ensure that the guide screw moves up and down stably.
[0014] As an optional solution of the hydraulic climbing formwork device for bridge piers described in this invention, the wall-mounted module includes a wall-mounted base and a hanger. The hanger is fixedly connected to the surface of the wall-mounted base, and a limit groove is formed on the surface of the hanger. The surface of the wall-mounted base also has two threaded holes.
[0015] When the guide screw moves upward to determine the position of the wall mount module, once the guide screw has moved to the appropriate position, the installation position of the wall mount base can be determined by engaging the limiting groove on the inner side of the wall mount module's bracket with the guide screw, and then the wall mount base can be fixed by installing screws through the threaded holes on the surface of the wall mount base.
[0016] As an optional embodiment of the hydraulic climbing formwork device for bridge piers described in this invention, the hanging member is T-shaped and the top of the hanging member is higher than the wall-mounted base, and the limiting groove penetrates the upper and lower end faces of the hanging member.
[0017] When the guide screw moves upward, it passes through the limiting groove of the hanger, and the hanger is in close contact with the bracket, which can stably ensure the position of the wall-mounted base. At the same time, because the hanger is higher than the wall-mounted base, it is convenient to install the subsequent wall-mounted bracket module on the outside of the wall-mounted base, so as to achieve precise docking of the wall-mounted bracket module.
[0018] As an optional solution of the hydraulic climbing formwork device for bridge piers described in this invention, each set of wall-mounted bracket modules includes two wall-mounted bodies, an upper unit connecting plate, and a lower unit connecting plate. The upper side of the wall-mounted body is fixedly connected to the upper unit connecting plate, and the lower unit connecting plate is fixedly connected to the lower side of the wall-mounted body. The side of the upper unit connecting plate facing away from the wall-mounted body and the side of the lower unit connecting plate facing away from the wall-mounted body are flush.
[0019] When the wall-mounted base module and the wall-mounted bracket module are used together, they slide from the side to the upper and lower parts of the wall-mounted base via the upper and lower unit connecting plates. The brackets are used to fix the upper unit connecting plate. At the same time, the two wall-mounted bodies are hollow in the center, which ensures that the guide screw can be smoothly inserted into it, so as to achieve precise positioning of the wall-mounted base module and the wall-mounted bracket module. The side of the upper unit connecting plate facing away from the wall and the side of the lower unit connecting plate facing away from the wall are set flush, which can ensure that one side of the upper unit connecting plate and the lower unit connecting plate is in close contact with the pier, so as to achieve the purpose of stability.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] This invention features a guide screw, motor, shaft, drive gear, and driven gear on the inner side of the climbing guide rail. During the pre-installation of the upper-level wall mount and wall bracket, the motor is pre-started, driving the shaft to rotate. The shaft then drives the outer drive gear, which in turn drives the driven gear. This causes the guide screw inside the driven gear to move upwards. In conjunction with the wall mount module, the installation position of the wall mount module can be determined. This design ensures precise installation of the wall mount module, preventing misalignment between the climbing guide rail and the wall mount / wall bracket, thus guaranteeing the construction schedule.
[0022] When the driven gear drives the internal guide screw to move, a limit block is set at the bottom of the guide screw, and the outer side of the limit block is slidably connected to the climbing guide rail. This ensures that the guide screw moves upward and prevents it from rotating. At the same time, the threaded ring can cooperate with the fixed frame to achieve stable upward movement of the guide screw.
[0023] A limiting groove is provided on the outside of the hanger. This allows the guide screw to be positioned inside the limiting groove when it moves upward, thus limiting the wall-mounted base. During the climbing formwork process, the guide screw can be moved upward and inserted into the limiting groove to determine the position of the wall-mounted base. Then, the screw can be used to fix the wall-mounted base through the threaded hole, preventing misalignment between the climbing guide rail, the wall-mounted base, and the wall-mounted hanger. This ensures the normal operation of the climbing formwork and guarantees the construction period.
[0024] To ensure the guide screw can stably engage with the limiting groove on the outside of the hanger, the wall-mounted unit is connected by an upper unit connecting plate and a lower unit connecting plate. The center is hollowed out to facilitate the guide screw's smooth insertion into the limiting groove, thus preventing the positioning purpose of the guide screw from being affected when the wall-mounted module and the wall-mounted base module are engaged.

[0032] Example 1:
[0033] Please see Figure 1 and Figure 2 The present invention provides a technical solution:
[0034] A hydraulic climbing formwork device for bridge piers includes a connecting pier 1 and a climbing guide rail 4. A wall-mounted bracket module 6 is installed on the side of the connecting pier 1 by screws, and a wall-mounted hanging bracket module 7 for supporting the climbing guide rail 4 is installed at the other end of the wall-mounted bracket module 6. The climbing guide rail 4 for climbing the frame is provided on the outer side of the wall-mounted hanging bracket module 7. A positioning module 5 for guiding is installed on the side of the climbing guide rail 4 facing the connecting pier 1. A connecting body 2 is detachably connected to the other end of the climbing guide rail 4, and a climbing hydraulic rod 3 is fixedly connected to the other end of the connecting body 2. The other end of the climbing hydraulic rod 3 is fixedly connected to a hydraulic operating platform.
[0035] During the climbing formwork device's ascent, wall-mounted brackets and wall-mounted hangers need to be installed at the previous level. Then, hydraulic equipment drives the guide rail upwards. After the guide rail connects with the wall-mounted brackets and hangers, the next level's wall-mounted brackets and hangers are removed. However, this setup has the following problems: Pre-installing the wall-mounted brackets and hangers before the guide rail moves upwards cannot ensure precise vertical alignment between the wall-mounted brackets and the guide rail. If there is any deviation between the wall-mounted brackets and the guide rail, the guide rail cannot be connected and fixed to the wall-mounted brackets, hindering the climbing formwork operation. Readjusting the position of the wall-mounted brackets and hangers is time-consuming and delays the construction schedule. In contrast, this device, during the climbing formwork operation, pre-activates the positioning module 5. When the positioning module 5 extends to a certain height... The position of the wall-mounted module 6 can be determined by its cooperation with the wall-mounted module 6. Then, the wall-mounted module 6 is fixed to the surface of the pier 1 with screws. Then, the wall-mounted hanging module 7 is installed. After the positioning module 5 is reset, the climbing hydraulic rod 3 is started to drive the climbing guide rail 4 to move upward in a cyclical manner. One end of the climbing hydraulic rod 3 is fixedly connected to the hydraulic operating platform (not shown in the figure) to drive the climbing guide rail 4 to move upward stably. The climbing hydraulic rod 3 driving the climbing guide rail 4 to move upward is a prior art in this field, so it will not be described in detail here. It is precisely cooperated with the wall-mounted module 6 and the wall-mounted hanging module 7 to achieve the purpose of fixation. This setting avoids the misalignment of the wall-mounted module 6 and the wall-mounted hanging module 7 with the climbing guide rail 4, ensuring accurate installation and ensuring the construction period.
[0036] Example 2
[0037] This embodiment is an improvement made to Implementation 1. Please refer to [link / reference]. Figure 1 , Figure 3 and Figure 4 Specifically, the positioning module 5 includes a fixed frame 501 and a guide screw 502. The outer side of the fixed frame 501 is fixedly connected to the climbing guide rail 4. A motor 503 is fixedly connected inside the fixed frame 501. A rotating shaft 504 is fixedly connected to the end of the main shaft of the motor 503. The other end of the rotating shaft 504 is rotatably connected to the fixed frame 501. A drive gear 505 is fixedly connected to the outer side of the rotating shaft 504. A driven gear 506 meshes with the outer side of the drive gear 505. The guide screw 502 is helically connected inside the driven gear 506.
[0038] During the climbing process, the motor 503 is pre-started, which drives the rotating shaft 504 to rotate. The rotating shaft 504 drives the outer drive gear 505 to rotate, which in turn drives the outer driven gear 506 to rotate. This causes the inner guide screw 502 to move upward. After the guide screw 502 moves upward to a certain position, the installation position of the wall mount module 6 can be determined by engaging it with the wall mount module 6. This ensures that the climbing guide rail 4 is aligned with the wall mount module 6 and the wall mount bracket module 7 when it moves upward, facilitating the installation of the climbing guide rail 4 and saving time wasted due to misalignment between the wall mount module 6 and the climbing guide rail 4.
[0039] Example 3
[0040] This embodiment is an improvement upon the two implementation examples. Please refer to [link / reference]. Figure 4 Specifically, the outer side of the aforementioned guide screw 502 is also screwed with a threaded ring 507, and the outer side of the threaded ring 507 is fixedly connected to the climbing guide rail 4.
[0041] To ensure the guide screw 502 moves upward stably and to prevent it from tilting, a threaded ring 507 is provided. The threaded ring 507 cooperates with the driven gear 506 to ensure that the guide screw 502 is in a vertical state, which is used to ensure subsequent positioning.
[0042] Example 4
[0043] This embodiment is an improvement upon the three implementation examples. Please refer to [link / reference]. Figure 4 Specifically, the bottom of the guide screw 502 is fixedly connected to a limiting block 508, and the limiting block 508 is a rectangular plate. One side of the limiting block 508 is slidably connected to the climbing guide rail 4.
[0044] When the guide screw 502 moves upward, in order to prevent the driven gear 506 from driving the guide screw 502 to rotate, a limit block 508 is installed at the bottom of the guide screw 502, and the outer side of the limit block 508 is slidably connected to the climbing guide rail 4, which is used to ensure that the guide screw 502 moves up and down stably.
[0045] Example 5
[0046] This embodiment is an improvement upon the four implementation examples. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 5 Specifically, the aforementioned wall mount module 6 includes a wall mount base 601 and a hanger 602. The hanger 602 is fixedly connected to the surface of the wall mount base 601. A limiting groove 603 is formed on the surface of the hanger 602. Two threaded holes 604 are also formed on the surface of the wall mount base 601.
[0047] When the guide screw 502 moves upward and determines the position of the wall mount module 6, after the guide screw 502 moves to the appropriate position, the installation position of the wall mount base 601 can be determined by cooperating the limiting groove 603 on the inner side of the hanger 602 of the wall mount module 6 with the guide screw 502, and the wall mount base 601 can be fixed by installing screws through the threaded hole 604 opened on the surface of the wall mount base 601.
[0048] Example 6
[0049] This embodiment is an improvement upon the previous five implementations. Please refer to [link / reference]. Figure 5 Specifically, the aforementioned hanging piece 602 is T-shaped, and the top of the hanging piece 602 is higher than the wall-mounted base 601. The aforementioned limiting groove 603 penetrates the upper and lower end faces of the hanging piece 602.
[0050] When the guide screw 502 moves upward, it passes through the limiting groove 603 of the hanger 602, and the hanger 602 is in close contact with the bracket 602, which can stably ensure the position of the wall-mounted base 601. At the same time, because the hanger 602 is higher than the wall-mounted base 601, it is convenient for the subsequent wall-mounted bracket module 7 to be installed on the outside of the wall-mounted base 601, so as to achieve precise docking of the wall-mounted bracket module 7.
[0051] Example 7
[0052] This embodiment is an improvement upon the previous six implementations. Please refer to [link / reference]. Figure 1 and Figure 6 Specifically, each of the above-mentioned wall-mounted bracket modules 7 includes two wall-mounted bodies 701, an upper unit connecting plate 702, and a lower unit connecting plate 703. The upper side of the wall-mounted body 701 is fixedly connected to the upper unit connecting plate 702, and the lower unit connecting plate 703 is fixedly connected to the lower side of the wall-mounted body 701. The side of the upper unit connecting plate 702 facing away from the wall-mounted body 701 and the side of the lower unit connecting plate 703 facing away from the wall-mounted body 701 are flush.
[0053] When the wall-mounted base module 6 and the wall-mounted bracket module 7 are used together, they slide from the side to the upper and lower parts of the wall-mounted base 601 via the upper unit connecting plate 702 and the lower unit connecting plate 703. The bracket 602 is used to fix the upper unit connecting plate 702. At the same time, the two wall-mounted bodies 701 are hollow in the center. This ensures that the guide screw 502 can be smoothly inserted into it, so as to achieve precise positioning of the wall-mounted base module 6 and the wall-mounted bracket module 7. The side of the upper unit connecting plate 702 facing away from the wall-mounted body 701 and the side of the lower unit connecting plate 703 facing away from the wall-mounted body 701 are flush. This ensures that the side of the upper unit connecting plate 702 and the lower unit connecting plate 703 are in close contact with the pier 1, so as to achieve the purpose of stability.
[0054] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only for the purpose of helping to understand the method and core ideas of the present invention. The above descriptions are only preferred embodiments of the present invention.
