Description

Technical Field

[0001] This utility model belongs to the field of pier construction, and in particular relates to a modular main platform for climbing formwork used in bridge pier construction and a climbing formwork for bridges. Background Technology

[0002] In the construction of bridge piers, climbing formwork is also required. It typically includes a control platform, a top platform, a climbing mechanism, and a translating trolley. The translating trolley is positioned between the control platform and the top platform, connected by horizontal plates and vertical back braces. The translating trolley is connected to the control platform by machine position vertical back braces. During use, the horizontal plates, vertical back braces, and machine position vertical back braces are fixedly connected to the side of the pier using tie rods and other structures. When the climbing formwork is ascending, the fixed connections between the horizontal plates, vertical back braces, and machine position vertical back braces and the pier are first removed. The translating trolley then moves the horizontal plates, vertical back braces, and top platform away from the pier. The climbing mechanism then drives the control platform upwards, thereby raising the entire climbing formwork.

[0003] To ensure the smooth movement of the horizontal plates, vertical back ribs, and module top platform using a translating trolley, guide rails are typically installed inside the translating trolley. However, due to the significant weight of the module top platform and the influence of wind, relying solely on guide rails for guidance and sliding connection would cause the horizontal plates, vertical back ribs, and module top platform to sway. In strong winds, this could even lead to the overturning of the horizontal plates, vertical back ribs, and module top platform, resulting in a safety accident. Utility Model Content

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0023] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0024] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0025] Please see Figure 1-5This utility model provides a modular main platform for climbing formwork used in bridge pier construction, including: a mounting base 1, a translation base 2, and a drive mechanism 3; the translation base 2 and the drive mechanism 3 are mounted on the mounting base 1, and the drive mechanism 3 is connected to the translation base 2; the translation base 2 has a first position and a second position on the mounting base 1; the drive mechanism 3 is used to drive the translation base 2 to move between the first position and the second position; the mounting base 1 is provided with a plurality of first clearance grooves 11, and the bottom of the translation base 2 is provided with a plurality of mounting blocks 21 and a plurality of limiting blocks 22, the first clearance grooves 11, the mounting blocks 21 and the limiting blocks 22 are arranged in a one-to-one correspondence, one end of the mounting block 21 passes through the first clearance groove 11 and is connected to the limiting block 22, and the width of the limiting block 22 is greater than the width of the first clearance groove 11.

[0026] In practice, the module top platform 6 and the horizontal plate and vertical back rib 7 can be set on the translation seat 2, and the mounting seat 1 is set on the top of the control platform 5. The first position corresponds to the position where the horizontal plate and vertical back rib 7 are fixedly connected to the pier column; the second position corresponds to the position where the horizontal plate and vertical back rib 7 and the module top platform 6 are moved away from the pier column before the climbing formwork is lifted.

[0027] The width of the limiting block 22 is greater than the width of the first clearance groove 11, so that the side of the limiting block 22 near the mounting base 1 abuts against the bottom surface of the mounting base 1. That is, the mounting block 21 and the limiting block 22 form a hook-like structure, which limits the translation seat 2 to the mounting base 1. This prevents the translation seat 2, as well as the horizontal plate and vertical back rib 7 and the module top platform 6 set on the top surface of the translation seat 2, from overturning when subjected to wind force, thus ensuring the safety of construction personnel. Furthermore, the width of the mounting block 21 is less than or equal to the width of the first clearance groove 11, preferably the width of the mounting block 21 is equal to the width of the first clearance groove 11, further ensuring that the translation seat 2 can be limited to the mounting base 1.

[0028] Because the mounting base 1 is provided with a first clearance groove 11, and the limiting block 22 is correspondingly provided with the first clearance groove 11, during use, construction materials such as concrete will fall from the first clearance groove 11 onto the control platform 5. In this embodiment, in order to prevent construction materials from falling onto the surface of the limiting block 22 near the mounting base 1, the side of the limiting block 22 away from the pier is set to be flush with the side of the translation seat 2 away from the pier. In this way, construction materials can only fall onto the control platform 5 or the translation seat 2, preventing construction materials from accumulating on the side of the limiting block 22 near the mounting base 1.

[0029] In order to increase the contact area between the limiting block 22 and the bottom surface of the mounting base 1 after the translation seat 2 moves to the first position and the second position, so as to ensure that the translation seat 2 can be stably limited to the first position or the second position, the length of the limiting block 22 in this embodiment is greater than the length of the mounting block 21. That is, from the perspective of the extension direction perpendicular to the first clearance groove 11 and the cross section perpendicular to the translation seat 2, the limiting block 22 and the mounting block 21 are combined into a T-shaped structure.

[0030] Please continue reading. Figure 1-5 The mounting base 1 is also provided with a second clearance groove 12, and the bottom of the translation base 2 is also provided with a transmission component 23. The driving mechanism 3 includes a driving component 31 disposed at the bottom of the mounting base 1. The transmission component 23 passes through the second clearance groove 12 and is connected to the movable end of the driving component 31. The multiple first clearance grooves 11 are divided into two groups, and the two groups of first clearance grooves 11 are symmetrically arranged on both sides of the extension direction of the second clearance groove 12. The transmission component 23 can be a block structure fixedly disposed on the bottom surface of the translation base 2. In this embodiment, there are two first clearance grooves 11, that is, one first clearance groove 11 in each group. Correspondingly, there are two mounting blocks 21 and two limiting blocks 22. The two first clearance grooves 11 are symmetrically arranged on both sides of the extension direction of the second clearance groove 12, further ensuring that the translation base 2 can be limited on the mounting base 1. Of course, in other implementations, the number of first clearance grooves 11 can also be 4, 6, etc., and this embodiment does not limit this.

[0031] The top of the mounting base 1 may also be provided with a slide rail, and the bottom of the translation base 2 may be provided with a slide groove, so as to realize the sliding connection between the mounting base 1 and the translation base 2. The slide rail can be a T-shaped guide rail 32, and the slide groove can be a T-shaped groove. Through the cooperation of the T-shaped rail and the T-shaped groove, not only can it play a role in sliding connection, but it can also play a role in limiting the movement of the translation base 2 in other directions except for the translational movement between the first position and the second position.

[0032] Please continue reading. Figure 1-5 In this embodiment, the main platform of the climbing formwork for bridge pier construction also includes a limiting mechanism, which is set corresponding to the first position; the driving mechanism 3 is also used to drive the limiting mechanism to move so as to limit the translation seat 2 to the first position.

[0033] Specifically, the drive mechanism 3 also includes a first trigger 33; the movable end of the drive component 31 is connected to the first trigger 33; the mounting base 1 is provided with two third clearance grooves 13, which are through grooves provided on the mounting base 1. The bottom of the translation base 2 is provided with two locking blocks 24; the limiting mechanism includes a trigger component 41, two opposing locking claws 42, and two reset components 43; the reset components 43, the third clearance groove 13, the locking claws 42, and the locking blocks 24 are arranged in a one-to-one correspondence; the fixed end of the locking claw 42 is slidably connected to the mounting base 1, and the clamping end of the locking claw 42 passes through the third clearance groove 13 and connects to the locking block 24; the fixed end of the reset component 43 is provided on the bottom surface of the mounting base 1, and the movable end of the reset component 43 is connected to the locking claw 42, used to drive the two locking claws 42 to move towards each other; the trigger component 41 is provided on the bottom surface of the mounting base 1, and at least partially located between the two locking claws 42, the trigger component 41 is used to connect with the first trigger member 33, and the drive member 31 drives the trigger component 41 to move, so as to drive the two locking claws 42 to move away from each other. The drive member 31 can be a motor or other drive element. In this embodiment, the drive member 31 is a hydraulic cylinder, which has a large output torque to facilitate the movement of the translation base 2.

[0034] Please see Figure 4 , 6 The bottom of the translation seat 2 is provided with two locking grooves 25, which are connected to the corresponding first clearance grooves 11. Locking blocks 24 are provided on the opposite sidewalls of the two locking grooves 25. A first clearance gap 26 exists between the locking block 24 and the bottom of the locking groove 25, and a second clearance gap 27 exists between the side of the locking block 24 away from the pier and the sidewall of the locking groove 25 away from the pier. The clamping end of the claw 42 is provided with a first side plate 421, a second side plate 422, and a horizontal plate 423. The first side plate 421, the second side plate 422, and the horizontal plate 423 are arranged perpendicularly to each other. The first side plate 421 and the second side plate 422 are perpendicular to the fixed end of the claw 42, and the horizontal plate 423 is located on the end of the first side plate 421 and the second side plate 422 away from the fixed end of the claw 42. When the claw 42 and the locking block 24 are engaged, the horizontal plate 423 is partially located within the first clearance gap 26, and the second side plate 422 is partially located within the second clearance gap 27. This prevents the translation seat 2 and the mounting seat 1 from tilting by the side contact between the horizontal plate 423 and the locking block 24. The action of the second side plate 422 and the locking block 24 prevents the translation seat 2 from moving to the second position.

[0035] When the pawl 42 engages with the locking block 24, the transmission component 23 abuts against the side wall of the second clearance groove 12 near the pier, thus preventing the translation seat 2 from continuing to move closer to the pier. In this embodiment, the transmission component 23, pawl 42, and locking block 24 are used to achieve the function of upper limit positioning of the translation seat 2 on the mounting base 1, preventing changes in the relative position of the translation seat 2 and the mounting base 1.

[0036] The first trigger 33 may include a first trigger 33 body, a fourth clearance groove 331, and a first triangular trigger part 332. The third clearance groove 13 is a through groove structure, and the transmission member 23 passes through the second clearance groove 12 and is located in the fourth clearance groove 331. One side wall of the first triangular trigger part 332 may be integrally formed with the first trigger 33 body. The other two side walls of the first triangular trigger part 332 are used to trigger the movement of the second trigger 411. The side wall of the first triangular trigger part 332 near the pier is defined as the first trigger part 3321, and the side wall away from the pier is defined as the second trigger part 3322.

[0037] The trigger assembly 41 may include a second trigger 411 and a cam 412. The cam 412 is rotatably connected to the bottom surface of the mounting base 1 and is located between two jaws 42, abutting against the fixed ends of the two jaws 42. The second trigger 411 is slidably connected to the bottom surface of the mounting base 1, such as through a guide rail. One end of the second trigger 411 is provided with a second triangular trigger portion adapted to the first triangular trigger portion 332. The side wall of the second triangular trigger member near the pier is defined as the third trigger portion 4112, and the side wall away from the pier is defined as the fourth trigger portion 4113.

[0038] like Figure 1 As shown on the right, at this time, the translation seat 2 is in the first position, and the two jaws 42 are in a clamping state. When the drive mechanism 3 moves the translation seat 2 from the first position to the second position, the first trigger part 3321 of the first trigger member 33 first abuts against the third trigger part 4112 of the second trigger member 411, causing the second trigger member 411 to move to the right on the mounting seat 1. The second trigger member 411 drives the cam 412 to rotate, which in turn drives the two jaws 42 to move in opposite directions, so that the two jaws 42 are disengaged from the clamping block 24 and are in an unclamped state. During this process, the transmission member 23 is in the fourth clearance groove 331. At this time, the transmission member 23 does not abut against the side wall of the fourth clearance groove 331, that is, the translation seat 2 does not move relative to the mounting seat 1.

[0039] When the first triangular trigger part 332 abuts against the vertex of the second triangular trigger part, the two claws 42 are completely disengaged from the block 24, and the transmission component 23 abuts against the side wall of the fourth clearance groove 331 near the pier. As the drive component 31 continues to move... Figure 1As the first trigger 33 moves downwards, its second trigger portion 3322 abuts against its fourth trigger portion 4113. At this time, under the action of the reset component 43 and as the force of the second trigger 411 gradually diminishes, the two claws 42 move closer together. Simultaneously, the transmission component 23 abuts against the side wall of the fourth clearance groove 331 near the pier, meaning the drive component 31 drives the translation seat 2 to move downwards. During this process, as the translation seat 2 moves, the claws 42 gradually move outside the locking groove 25 of the translation seat 2. As the translation seat 2 continues to move, the claws 42, under the action of the reset component 43, reset to the clamping state. In other words, during the contact between the second trigger part 3322 and the fourth trigger part 4113, the two claws 42 switch from an unclamped state to a clamped state, and the two claws 42 move from inside the clamping groove 25 to outside the clamping groove 25; and with the movement of the translation seat 2, the claws 42 do not engage with the clamping block 24, that is, in the clamping state at this time, the two claws do not clamp the clamping block 24.

[0040] In order to enable the second trigger 411 to drive the cam 412 to rotate, in this embodiment a gear 413 is coaxially arranged on the cam 412 and a rack 4111 is arranged on the second trigger 411. Thus, the cam 412 is driven to rotate through the meshing of the gear 413 and the rack 4111.

[0041] Please see Figure 7 The reset assembly 43 may include a guide post 431, a guide sleeve 432, and an elastic element 433. One end of the guide post 431 is disposed on the fixed end of the jaw 42, and the other end is located inside the guide sleeve 432. The end of the guide sleeve 432 away from the guide post 431 is connected to the mounting base 1. The elastic element 433 is sleeved on the guide post 431, with one end connected to the jaw 42 and the other end connected to the guide sleeve 432. The elastic element 433 can be an elastic structure with elastic force; in this embodiment, the elastic element 433 is a spring. Through the arrangement of the guide post 431, the elastic element 433, and the guide sleeve 432, the two jaws can be reset and maintained in the state of clamping the clamping block 24.

[0042] Please see Figure 8 On the other hand, this utility model also provides a climbing formwork for bridges, including a control platform 5, a modular top platform 6, and a translation trolley as described above. A mounting base 1 is located on top of the control platform 5 and can be connected to the control platform 5 via a machine position vertical back brace 8. The modular top platform 6 is located on the top surface of the translation base 2 and can be mounted on the top surface of the translation base 2 via a horizontal plate vertical back brace 7. When fixing the climbing formwork for bridge pier construction onto the pier, the machine position vertical back brace 8 and the horizontal plate vertical back brace 7 are also connected to the pier via tie rods or other structures.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
