Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a working platform for the construction of high bridge piers. Background Technology

[0002] In modern bridge engineering, the construction of high piers is a crucial step. To facilitate workers' work at heights, working platforms are typically installed at specific heights on the piers. These platforms provide the necessary operating space and safety guarantees for subsequent processes such as formwork erection, concrete pouring, and rebar tying.

[0003] Construction activities on work platforms, such as using pneumatic drills or electric drills for impact operations or installing large equipment, inevitably generate strong vibrations and impact forces. Although existing work platforms can achieve the static load-bearing capacity of the platform and a rigid connection with the bridge piers to ensure that the platform will not fall, the following problems still exist: The vibrations generated by the work platform are transmitted directly to the bridge pier structure with almost no attenuation. For high piers that are in the curing period or whose structure is not yet fully stable, this continuous external vibration input may cause microcracks in the concrete, affecting the long-term durability and safety of the structure. At the same time, the presence of vibration will also reduce the operating comfort and stability of the platform itself, affecting the construction accuracy and the safety of the workers. Therefore, a work platform for the construction of high bridge piers is proposed to solve the above problems. Utility Model Content

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Reference Figures 1 to 7 This utility model provides a working platform for the construction of high bridge piers, which aims to solve the problems in the prior art where the construction vibration of the working platform is directly transmitted to the bridge pier 1, affecting the structural stability, and the rigid fixing method is prone to wear or loosening under vibration.

[0023] A working platform for the construction of high bridge piers includes a fixed plate 2; The bottom end of the fixed plate 2 is provided with several circumferentially arranged buffer structures 3 and fixing mechanisms 4; the fixed plate 2 is used as the main platform to support the workers and equipment, and the buffer structures 3 are used to absorb and dissipate the vibration energy generated when the fixed plate 2 is working.

[0024] The buffer structure 3 includes a second fixing plate 31, the top end of which is fixedly connected to the bottom end of a first fixing plate 2, and a first connecting plate 32 is fixedly connected to the bottom end of the second fixing plate 31. It also includes a second connecting plate 33, which is U-shaped.

A movable disk 34 is fixedly connected to the bottom end of the second connecting plate 33, and two connecting disks 35 are rotatably connected to the bottom end of the movable disk 34. The connecting disks 35 are connected to each other through a damping column 301. It also includes a housing 37, which is fitted onto the damping column 301. A spiral groove 38 is opened on the inner wall of the housing 37. A guide rod 36 is fixedly connected to the outer wall of the connecting plate 35. The guide rod 36 can slide along the spiral groove 38. The bottom end of the housing 37 is connected to the pier 1.

[0025] Application results: This utility model, by setting up a multi-level buffer structure 3 composed of a fixed plate 2 31, a connecting plate 1 32, a connecting plate 2 33, a moving disk 34, a connecting disk 35, a damping column 301, a guide rod 36, a support assembly 39, and a damping rod 1 398, solves the problem in the prior art where the vibration of the working platform is directly transmitted to the bridge pier 1, which easily affects the structural stability. It achieves the technical effect of multi-level synergy and efficient vibration absorption, and significantly reduces the impact of construction on the bridge pier 1.

[0026] In some embodiments, the guide rod 36 is covered with a buffer pad 391, which can reduce the friction between the guide rod 36 and the spiral groove 38, and also has a certain shock absorption and buffering effect.

[0027] Application results: By creating a spiral groove 38 on the inner wall of the outer shell 37 and sliding the buffer pad 391 on the support assembly 39 within the spiral groove 38, precise guidance and limiting are provided for the complex movement of the buffer structure 3 during energy dissipation. This solves the problem of possible offset or jamming during the movement of the buffer assembly, achieving the technical effect of ensuring a smooth and controllable buffering process. In some embodiments, a support assembly 39 is provided between the outer shell 37 and the pier 1. The support assembly 39 also includes a connecting plate 392. The connecting plate 392 is fixedly connected to the bottom end of the outer shell 37. A connecting block 399 is hinged to the bottom end of the connecting plate 392. A support rod 394 is fixedly connected to the bottom end of the connecting block 399. One end of the support rod 394 is hinged to a support plate 393, and the other end is hinged to a support plate 395. The support plate 393 is fixedly connected to the pier 1, and the support plate 395 is fixedly connected to the fixing plate 2. The support assembly 39 can play the function of constraint and limitation, making the structure more stable while the buffer structure 3 absorbs vibration.

[0028] In some embodiments, a connecting block 396 is fixedly connected to the bottom surface of the support rod 394, and a damping rod 398 is connected between adjacent connecting blocks 396; the damping rod further enhances the vibration absorption capacity of the device.

[0029] In some embodiments, both sides of the connecting block 396 are provided with fixing rods 397, and the two ends of the damping rod 398 are respectively hinged to the two adjacent connecting blocks 396.

[0030] In some embodiments, the fixing mechanism 4 includes a fixing chamber 41, which is disposed within the fixing plate 2. The fixing mechanism 4 also includes a semi-ring clamping plate 43, the inner wall of which is clamped onto the outer wall of the pier 1. A damping rod 42 and a clamping mechanism are also connected between the outer wall of the semi-ring clamping plate 43 and the fixing chamber 41.

[0031] Application results: By setting up a fixing mechanism 4, the mechanism uses a control plate 47 to drive the moving block 46, the rotating rod 45 and the rotating chamber 44, and finally pushes the semi-ring clamp 43 to achieve a tight clamping and fixing of the pier 1. At the same time, a damping rod 42 is set between the fixing chamber 41 and the semi-ring clamp 43 for flexible connection. This solves the problem that the rigid fixing method in the prior art is prone to loosening and wear under vibration, and may damage the surface of the pier 1 due to stress concentration. It achieves the technical effect of firm and reliable fixing, convenient loading and unloading, and elastic buffering capacity.

[0032] In some embodiments, the clamping mechanism includes a rotating chamber 44, a rotating rod 45, and a moving block 46; the rotating chamber 44 is fixedly connected to the outer wall of the semi-ring clamping plate 43, one end of the rotating rod 45 is rotatably connected to the rotating chamber 44, and the other end of the rotating rod 45 is rotatably connected to the moving block 46, which can slide and be fixed in the fixed chamber 41.

[0033] In some embodiments, a T-shaped portion is provided below the movable block 46, and a groove is provided on the top surface of the fixed compartment 41, allowing the T-shaped portion to slide within the groove.

[0034] In some embodiments, a control plate 47 and a set screw are also included. The control plate 47 is fixedly connected to the top of the movable block 46, and the set screw is threadedly connected to the control plate 47. The set screw can support the top surface of the fixed plate 2. This realizes the fixation of the fixing mechanism 4 and improves the safety during construction.

[0035] In some embodiments, a guardrail 5 is fixedly connected to the top of the fixed plate 2, effectively ensuring the safety of personnel working on high piers. The implementation principle of this application embodiment is as follows: A guardrail 5 is fixedly connected to the top of the fixed plate 1 2, and a buffer structure 3 is fixedly connected to the bottom of the pier 1. A fixing mechanism 4 is fixedly connected inside the fixed plate 1 2. The tops of multiple fixed plates 2 31 in the buffer structure 3 are fixedly connected to the bottom of the fixed plate 1 2. The vibration of the fixed plate 1 2 will synchronously drive the multiple fixed plates 2 31 fixedly connected to its bottom, so that the fixed plates 2 31 will transfer the vibration energy to the connecting plate 1 32 fixedly connected to its bottom. Since the connecting plate 1 32 and the connecting plate 2 33 are hinged, the vibration will cause the connecting plate 2 33 to rotate around the connecting plate 1 32 at a certain angle. The movable disk 34 fixedly connected to the bottom of the connecting plate 2 33 will be displaced with the rotation of the connecting plate 2 33, thereby pushing the connecting disk 35 rotatedly connected to the bottom of the movable disk 34 to move. The guide rod 36, which is fixedly connected to the outer wall of the connecting plate 35, moves with the movement of the connecting plate 35. The guide rod 36 is covered with a buffer pad 391, which slides along the spiral groove 38 opened on the inner wall of the outer shell 37 under the drive of the guide rod 36. The spiral groove 38 provides a stable movement trajectory for the buffer pad 391 and the guide rod 36, preventing them from deviating during the buffering process. At the same time, the two connecting plates 35, which are slidably connected inside the outer shell 37, are respectively connected to the upper connecting plate 2 33 and the lower connecting plate 392. During vibration transmission, they will move closer or further apart. When the two connecting plates 35 move to the side that is closer together, they will squeeze the damping column 301 fixedly connected between them. The damping column 301 absorbs part of the vibration energy through its own elastic deformation and damping characteristics, initially alleviating the vibration intensity. Furthermore, the connecting plate 392, which is fixedly connected to the bottom of the lower connecting plate 35, will transmit the remaining vibration energy to the connecting block 399, which is hinged to its bottom. The connecting block 399 will drive the support rod 394, which is fixedly connected to its bottom, to move. The support plate 393, which is hinged to one end of the support rod 394, will constrain the movement of the support rod 394 because it is fixedly connected to the pier 1. The support plate 395, which is hinged to the other end of the support rod 394, will act synchronously on the support rod 394 because its top end is fixed to the bottom end of the fixed plate 2. At this time, the support rod Under the dual constraints of support plate 393 and support plate 395, 394 further disperses vibration energy through its own rotational fine adjustment; at the same time, the connecting block 396 fixedly connected to the bottom surface of support rod 394, and the damping rod 398 externally hinged to the fixing rod 397 fixedly connected to both sides of it will rotate with the movement of support rod 394. The damping rod 398 consumes vibration energy again through its own damping effect, ultimately achieving effective buffering of the vibration generated when the fixed plate 2 is working, reducing the impact of vibration on the entire working platform and the construction of pier 1.

[0036] The inner wall of the fixing plate 2 is fixedly connected to the fixing chamber 41 of the fixing mechanism 4. The fixing chamber 41 is the core load-bearing component of the fixing mechanism 4. The fixing chamber 41 serves as the installation foundation for the entire fixing mechanism 4 and provides stable support for subsequent components. The damping rod 42 is fixedly connected to one end of the fixing chamber 41. It is not only a key component connecting the fixing chamber 41 and the semi-ring clamp 43, but also has elastic buffering capacity, which can initially alleviate the rigid force between the two. When fixing plate 2 to pier 1 is required, multiple semi-ring clamps 43 pre-fitted to the outer top of pier 1 are indirectly connected to the fixing chamber 41 by fixing one end of the semi-ring clamps 43 to the damping rod 42. Because the semi-ring clamps 43 have a certain degree of elasticity, they can adapt to the slight curvature or unevenness of the pier 1 surface when fitting against the outer wall, ensuring a tight fit and avoiding collision damage that is easily caused when traditional rigid clamps directly contact the pier 1. A rotating chamber 44 fixedly connected to the other end of the semi-ring clamps 43 provides a rotation support point for the rotating rod 45. Rotating rods 45 are rotatably connected within multiple rotating chambers 44. These rotating rods 45 can slide within the fixing chamber 41. Through the dual action of rotation and sliding, fine-tuning of the fixing position is achieved, further optimizing the fit between the semi-ring clamps 43 and pier 1. The movable block 46, which is fixedly connected to one end of the rotating rod 45, moves synchronously with the sliding of the rotating rod 45. The top of the movable block 46 is equipped with a control plate 47, which is the key component for the final locking of the fixing mechanism 4. The operator adjusts the two set screws connected to the inner wall of the control plate 47 so that the bottom end of the set screw supports the top surface of the fixing plate 2. During the tightening process, the control plate 47 drives the rotating rod 45 to generate directional movement through the movable block 46. The rotating rod 45 then pushes the semi-ring clamp 43 towards the pier 1 through the rotating chamber 44 to further press it until the semi-ring clamp 43 and the outer wall of the pier 1 form a stable clamping state. At this time, the fixing plate 2 is firmly connected to the pier 1 through the fixing mechanism 4. In subsequent operations, if the fixed plate 2 experiences slight displacement due to construction vibration, the damping rod 42 between the fixed chamber 41 and the semi-ring clamp 43 will absorb the vibration energy through its own elastic deformation. At the same time, the elastic characteristics of the semi-ring clamp 43 will further buffer the force between the fixed plate 2 and the pier 1, preventing wear or damage at the connection due to rigid transmission of vibration. Ultimately, this achieves effective fixation of the fixed plate 2 and the pier 1, while ensuring the safety and durability of the connection.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
