Description

Technical Field

[0001] This utility model belongs to the field of pier construction, and in particular relates to a translation trolley 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 causing the entire climbing formwork to ascend.

[0003] Because the top of the translation trolley is slidably connected to the top of the control platform, or the translation trolley itself has a sliding connection mechanism, the sliding connection mechanism of the translation trolley or its own components needs to be limited during the upward climbing process to prevent the horizontal plates, vertical back ribs, and top platform of the module from swaying relative to the main platform of the module, which would affect the upward climbing efficiency of the climbing formwork. Furthermore, after the climbing is complete, the sliding connection mechanism of the translation trolley or its own components also needs to be limited to facilitate fixing the horizontal plates, vertical back ribs, and machine position vertical back ribs to the pier.

[0004] In existing technologies, bolts are typically used for positioning. This method requires that the relative position of the traverse trolley to the control platform or its own sliding connection mechanism remain unchanged, or experience only slight displacement, in order to secure it. However, since climbing formwork is typically a high-altitude operation, the relative position of the traverse trolley to the control platform or its own sliding connection mechanism often undergoes significant displacement due to wind and other forces. This makes it impossible for construction workers to secure the trolley, and in severe cases, it can even endanger their safety. Utility Model Content

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Please see Figure 1-3 This utility model provides a translation trolley, including: a mounting base 1, a translation base 2, a drive mechanism 3, a first limiting mechanism, and a second limiting mechanism; the translation base 2, the drive mechanism 3, the first limiting mechanism, and the second limiting mechanism are disposed on the mounting base 1, the translation base 2 has a first position and a second position on the mounting base 1, the first limiting mechanism is disposed corresponding to the first position, and the second limiting mechanism is disposed corresponding to the second position; the drive mechanism 3 is used to drive the translation base 2 to move between the first position and the second position, drive the first limiting mechanism to move so as to limit the translation base 2 to the first position, and drive the second limiting mechanism to move so as to limit the translation base 2 to the second position.

[0031] In specific implementation, the module top platform 7 and the horizontal plate and vertical back rib 8 can be set on the translation seat 2, and the mounting seat 1 is set on the top of the control platform 6. The first position corresponds to the position where the horizontal plate and vertical back rib 8 are fixedly connected to the pier column; the second position corresponds to the position where the horizontal plate and vertical back rib 8 and the module top platform 7 are moved away from the pier column before the climbing formwork is lifted. That is, in this embodiment, when the climbing formwork is lifted, the translation seat 2 is limited by the second limiting mechanism to fix the relative position between the translation seat 2 and the mounting seat 1, so as to prevent the horizontal plate and vertical back rib 8 and the module top platform 7 from shaking during the lifting process; after the lifting is completed, the translation seat 2 is limited by the first limiting mechanism to fix the relative position between the translation seat 2 and the mounting seat 1, so as to fix the horizontal plate and vertical back rib 8 on the pier column. Optionally, after the first and second limiting mechanisms limit the translation seat 2, the translation seat 2 can be fixed to the mounting seat 1 by means of bolts or other structures to further ensure that the relative position between the translation seat 2 and the mounting seat 1 does not change. Specifically, through holes for the screw to pass through are provided on the translation seat 2 and the mounting seat 1 respectively, so that the two can be fixed with bolts.

[0032] This embodiment uses a second limiting mechanism to limit the translation seat 2 to the second position, effectively preventing the horizontal plate and vertical back rib 8 and the module top platform 7 from swaying under wind force during the climbing process and when fixing the horizontal plate and vertical back rib 8 to the pier, thus ensuring the safety of construction personnel. Furthermore, after the drive mechanism 3 drives the translation seat 2 to the first or second position, the corresponding limiting mechanism automatically limits the translation seat 2, reducing the number of steps for construction personnel, improving their work efficiency, and also preventing the horizontal plate and vertical back rib 8 and the module top platform 7 from sliding under wind force after reaching the correct position, which would make it difficult for construction personnel to fix them securely.

[0033] To ensure that the translation seat 2 is stably positioned on the mounting base 1, this embodiment uses two first limiting mechanisms and two second limiting mechanisms, with the drive mechanism 3 located between the two first and second limiting mechanisms. This arrangement also ensures the stability of the drive mechanism 3's operation. For ease of explanation, the following description will use one first limiting mechanism and one second limiting mechanism, but this does not mean that this solution can only use one first limiting mechanism and one second limiting mechanism.

[0034] 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 rail, 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.

[0035] Please see Figure 1-5 The drive mechanism 3 may include a drive component 31 and a first trigger component 32. The drive component 31 is disposed on the bottom surface of the mounting base 1, and the movable end of the drive component 31 is connected to the translation base 2 and the first trigger component 32. The mounting base 1 is provided with two first clearance grooves 11, which are through grooves disposed on the mounting base 1. The bottom of the translation base 2 is provided with two locking blocks 21; the first limiting mechanism includes a trigger component 41, two opposing locking claws 42, and two reset components 43; the reset components 43, the first clearance groove 11, the locking claws 42, and the locking blocks 21 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 first clearance groove 11 and is connected to the locking block 21; 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, which is 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 is at least partially located between the two locking claws 42. The trigger component 41 is used to connect with the first trigger member 32, 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.

[0036] Please see Figure 5-6 The bottom of the translation seat 2 is provided with two locking grooves 23, which are connected to the corresponding first clearance grooves 11. Locking blocks 21 are provided on the opposite sidewalls of the two locking grooves 23. A first clearance gap 231 exists between the locking block 21 and the bottom of the locking groove 23, allowing clearance for the locking claw 42. A second clearance gap 232 exists between the side of the locking block 21 away from the pier and the sidewall of the locking groove 23 away from the pier. The clamping end of the locking 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 locking 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 locking claw 42. When the claw 42 engages with the block 21, the horizontal plate 423 is partially located within the first clearance gap 231, and the second side plate 422 is partially located within the second clearance gap 232. This prevents tilting between the translation seat 2 and the mounting seat 1 by the side contact between the horizontal plate 423 and the block 21. The action of the second side plate 422 and the block 21 prevents the translation seat 2 from moving to the second position.

[0037] Please see Figure 1-5The mounting base 1 may also be provided with a second clearance groove 12, which is a through groove. A transmission component 22 is provided on the bottom surface of the translation base 2. The transmission block can be a block-shaped structure fixedly mounted on the bottom surface of the translation base 2. The transmission component 22 passes through the second clearance groove 12 and connects to the movable end of the driving component 31. When the pawl 42 engages with the pawl 21, the transmission component 22 abuts against the side wall of the second clearance groove 12 near the pier, preventing the translation base 2 from continuing to move closer to the pier. In this embodiment, the transmission component 22, pawl 42, and pawl 21 are used to achieve the function of upper limit positioning of the translation base 2 on the mounting base 1, preventing changes in the relative position of the translation base 2 and the mounting base 1.

[0038] Please see Figure 1 The first trigger 32 may include a first trigger 32 body, a third clearance groove 321, and a first triangular trigger part 322. The third clearance groove 321 is a through groove structure, and the transmission member 22 passes through the second clearance groove 12 and is located in the third clearance groove 321. One side wall of the first triangular trigger part 322 may be integrally formed with the first trigger 32 body. The other two side walls of the first triangular trigger part 322 are used to trigger the movement of the second trigger 411. The side wall of the first triangular trigger part 322 near the pier is defined as the first trigger part 3221, and the side wall away from the pier is defined as the second trigger part 3222.

[0039] 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 4111 that is adapted to the first triangular trigger portion 322. The side wall of the second triangular trigger near the pier is defined as the third trigger portion 4113, and the side wall away from the pier is defined as the fourth trigger portion 4114.

[0040] 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 3221 of the first trigger member 32 first abuts against the third trigger part 4113 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, realizing that the two jaws 42 are disengaged from the clamping block 21 and are in an unclamped state. During this process, the transmission member 22 is in the third clearance groove 321. At this time, the transmission member 22 does not abut against the side wall of the third clearance groove 321, that is, the translation seat 2 does not move relative to the mounting seat 1.

[0041] When the first triangular trigger part 322 abuts against the vertex of the second triangular trigger part 4111, the two claws 42 are completely disengaged from the block 21, and the transmission component 22 abuts against the side wall of the third clearance groove 321 near the pier. As the drive component 31 continues to move... Figure 1 As the first trigger 32 moves downwards, its second trigger portion 3222 abuts against its fourth trigger portion 4114. 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 22 abuts against the side wall of the third clearance groove 321 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 23 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 3222 and the fourth trigger part 4114, the two claws 42 switch from an unclamped state to a clamped state, and the two claws 42 move from inside the clamping groove 23 to outside the clamping groove 23; and with the movement of the translation seat 2, the claws 42 do not engage with the clamping block 21, that is, in the clamping state at this time, the two claws do not clamp the clamping block 21.

[0042] In order to enable the second trigger 411 to drive the cam 412 to rotate, in this embodiment, a first gear 413 is coaxially arranged on the cam 412 and a first rack 4112 is arranged on the second trigger 411. Thus, the cam 412 is driven to rotate through the meshing of the first gear 413 and the first rack 4112.

[0043] Please see Figure 1 , 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 21.

[0044] Please see Figure 1-2 8. The drive mechanism 3 may also include a third trigger 33, which is also connected to the movable end of the drive component 31. In order to ensure the smooth operation of the drive component 31, the third trigger 33 and the bottom surface of the base can be slidably connected through a structure such as a guide rail.

[0045] The second limiting mechanism includes a first mounting block 51, a first limiting block 52, and a limiting component 53; a fourth clearance groove 13 is provided on the mounting base 1, and the fourth clearance groove 13 is a through groove structure. The first mounting block 51 is set on the bottom surface of the translation base 2, and one end of it passes through the fourth clearance groove 13 and connects to the first limiting block 52. The first mounting block 51 and the first limiting block 52 form an L-shaped structure; the width of the first limiting block 52 is greater than the width of the fourth clearance groove 13 to prevent the first limiting block 52 from passing through the fourth clearance groove 13; the limiting component 53 is set on the bottom surface of the mounting base 1 and is set corresponding to the second position; the third trigger 33 is connected to the limiting component 53. When the translation seat 2 is in the second position, the first mounting block 51 abuts against the side wall of the fourth clearance groove 13 away from the pier, and the first limiting block 52 abuts against the bottom surface of the mounting seat 1 near the side wall of the mounting seat 1. That is, the L-shaped structure formed by the first mounting block 51 and the first limiting block 52 hooks the mounting seat 1, preventing the translation seat 2 from tilting relative to the mounting seat 1. In addition, the limiting component 53 abuts against the side wall of the first limiting block 52 near the pier, thereby fixing the translation seat 2 to the mounting seat 1 through the action of the first mounting block 51, the first limiting block 52, and the limiting component 53.

[0046] The limiting component 53 may include a fixed frame 531, a rotating shaft 532, and a second limiting block 533. The fixed frame 531 is disposed on the bottom surface of the mounting base 1, the rotating shaft 532 is rotatably connected to the fixed frame 531, and the second limiting block 533 is disposed on the rotating shaft 532. The rotating shaft 532 is connected to a third trigger member 33. When the driving member 31 drives the translation base 2 to move from the first position to the second position, the trigger member is connected to the rotating shaft 532 to drive the rotating shaft 532 to rotate along the first direction. When the driving member 31 drives the translation base 2 to move from the second position to the first position, the trigger member drives the rotating shaft 532 to rotate along the second direction, and when the translation base 2 is in the first position, the trigger member disengages from the rotating shaft 532. The first direction and the second direction are opposite directions. In this embodiment, the first direction is clockwise and the second direction is counterclockwise.

[0047] Specifically, the limiting component 53 includes a second gear 534 disposed on the rotating shaft 532, and the third trigger 33 is a second rack. Through the meshing action of the second rack and the second gear 534, the rotating shaft 532 can be driven to rotate, thereby causing the second limiting block 533 and the first limiting block 52 to abut or not abut.

[0048] Please see Figure 8-9Furthermore, since the driving member 31 drives the third trigger member 33 to travel a relatively long distance, in order to avoid the rotation angle of the rotating shaft 532 being too large, causing the second limiting block 533 to abut against the fixed frame 531, in this embodiment, a second mounting block 535 is provided on the fixed frame 531, a spring plunger 536 is provided on the second mounting block 535, and a snap-fit ​​hole 5331 is provided on the second limiting block 533. The spring plunger 536 is used to connect with the snap-fit ​​hole 5331. When the driving member 31 drives the translation seat 2 to move from the first position to the second position, the third trigger member 33 meshes with the second gear 534 on the rotating shaft 532 to drive the rotating shaft 532 to rotate in the first direction, so that the spring plunger 536 on the fixed frame 531 disengages from the snap-fit ​​hole 5331 on the second limiting block 533, so that the second limiting block 533 can rotate with the rotating shaft 532 and finally abut against the first limiting block 52. When the driving member 31 moves the translation seat 2 from the second position to the first position, the third trigger member 33 is still engaged with the second gear 534, causing the second limiting block 533 to first disengage from the first limiting block 52. Then, during the rotation of the rotating shaft 532, the locking hole 5331 of the second limiting block 533 engages with the spring plunger 536. After the spring plunger 536 engages with the locking hole 5331, the third trigger member 33 disengages from the second gear 534, thereby keeping the second limiting block 533 engaged with the spring plunger 536.

[0049] Because the mounting base 1 is provided with a second clearance groove 12, and the first limiting block 52 is correspondingly provided with the second clearance groove 12, during use, construction materials such as concrete will fall from the second clearance groove 12 onto the control platform 6. In this embodiment, to prevent construction materials from falling onto the surface of the first limiting block 52 near the mounting base 1, the side of the first limiting block 52 near the second position is set to be flush with the side of the translation seat 2 near the second position. In this way, construction materials can only fall onto the control platform 6 or the translation seat 2, preventing construction materials from accumulating on the side of the first limiting block 52 near the mounting base 1.

[0050] Please see Figure 10 On the other hand, this utility model also provides a climbing formwork for bridges, including a control platform 6, a modular top platform 7, and a translation trolley as described above. A mounting base 1 is disposed on top of the control platform 6 and can be connected to the control platform 6 via a vertical back brace 9. The modular top platform 7 is disposed on the top surface of the translation base 2 and can be disposed on the top surface of the translation base 2 via a horizontal plate vertical back brace 8. When fixing the climbing formwork for bridges to the pier, the vertical back brace 9 and the horizontal plate vertical back brace 8 are also connected to the pier via structures such as tie rods.
