Description

A self-stabilizing temporary support device for prefabricated bridge piers suitable for rapid construction Technical Field

[0001] This invention relates to the field of bridge engineering technology, and specifically to a self-stabilizing temporary support device for prefabricated bridge piers suitable for rapid construction. Background Technology

[0002] In the field of bridge construction, precast bridge piers have gradually become an important method of industrialized bridge construction due to their advantages such as fast construction speed, controllable quality, and minimal environmental impact. Before precast bridge piers reach their final fixed strength, they usually need to be supported by temporary support devices to maintain their spatial stability and prevent displacement, tilting, or overturning.

[0003] In existing technologies, common temporary supports often use on-site erected steel pipe supports or specially welded custom steel support structures. These support structures are not only inefficient to install and difficult to dismantle, but also have poor versatility and are difficult to adjust to suit different specifications of bridge piers, resulting in their abandonment after use. They not only fail to meet the construction requirements of rapid installation and efficient turnover, but also have high construction costs. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, this invention proposes a self-stabilizing temporary support device for prefabricated bridge piers suitable for rapid construction, which can quickly support bridge piers of different specifications.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a precast bridge pier self-stabilizing temporary support device suitable for rapid construction, comprising a base, a support frame, and an adjustment mechanism; the base is an annular base; multiple sets of the support frames are arranged circumferentially on the base; the adjustment mechanism includes a slider and a driving component, multiple sliders are arranged circumferentially and movably disposed on the base, respectively connected to multiple sets of support frames, and the driving component can drive the sliders to move radially along the base.

[0006] The device is installed on the outside of the bridge pier, and the slider is driven by the drive component to move on the base and along its radial direction, thereby driving multiple sets of support frames to approach the bridge pier. The multiple sets of support frames support the bridge pier from multiple directions.

[0007] The beneficial effects of the aforementioned precast pier self-stabilizing temporary support device suitable for rapid construction are: by setting up multiple sets of movable support frames, the pier can be temporarily supported from multiple directions quickly. It not only has a good support effect, but is also applicable to piers of different specifications so that it can be reused and reduce the cost of use.

[0008] Furthermore, the driving component includes a toothed ring and push blocks. The toothed ring is rotatably disposed within the base. Multiple push blocks are arranged circumferentially around the toothed ring and are capable of moving along the tangential direction of the toothed ring. Each push block is provided with a rack that meshes with the toothed ring. Each push block is also provided with an inclined sliding groove. The two ends of the inclined sliding groove are located on different radial directions of the base. The slider is slidably connected to the inclined sliding groove of each push block.

[0009] By driving the gear ring to rotate, multiple push blocks can be moved along the tangent of the gear ring. The push blocks can move together with the slider through the inclined slide. Since the push blocks can only move radially along the base, the inclined slide can drive the push blocks to move radially along the base, thereby driving the support frame closer to or away from the central pier.

[0010] Furthermore, the drive unit also includes a hydraulic motor and a gear, the hydraulic motor being disposed within the base and connected to the gear, the gear meshing with a gear ring.

[0011] Hydraulic motors have the advantage of high torque output at low speeds, which can drive gears to rotate and drive the gear ring to rotate, thereby moving the support frame.

[0012] Furthermore, the base is also provided with a support rod, one end of which is rotatably mounted on the base, and the other end is provided with a ratchet; the support frame is provided with a support plate on the side near the outer circumference of the base, and the support plate is provided with multiple movably connected ratchet teeth in the vertical direction, and the ratchet can rotate downward in one direction relative to the ratchet teeth.

[0013] The ratchet at the end of the support rod abuts against the support plate on the outside of the support frame. When the support frame moves toward the inside of the base, the support rod rotates downward under the action of gravity, and at the same time the ratchet rotates on the ratchet teeth. Since the ratchet cannot rotate in the opposite direction relative to the ratchet teeth, it can hold the support plate and the support frame together, thus improving the support effect.

[0014] Furthermore, the support frame is provided in four sets, arranged in a cross shape.

[0015] The cross-shaped support frame can be used for both round and square bridge piers.

[0016] Furthermore, it also includes an adjustment mechanism two, wherein each of the two sets of opposing adjustment mechanisms is provided with an adjustment mechanism two, including a screw and a gear two. Two screws are provided in parallel and are rotatably mounted on the slider. The thread directions of the two screws are the same. The gear two is located between the two screws and meshes with the two screws on both sides respectively. The gear is connected to the bottom of the support frame through a rotating shaft.

[0017] The system drives two screws to rotate. When the screws rotate in the same direction, they cause the central gear two to move along the axial direction of the screws. This, in turn, moves the support frame via a shaft, allowing it to move closer to or further away from the pier, making it suitable for non-square rectangular piers. When the two screws rotate in opposite directions, they drive the central gear two to rotate, which in turn rotates the support frame via a shaft, adjusting its angle to suit irregularly shaped piers.

[0018] Furthermore, the bottom of the support frame is provided with a base plate, which is fitted and slidably mounted on the base, and the bottom is connected to the rotating shaft.

[0019] The base plate is slidably mounted on the base, which makes it easy to move or rotate the support frame on the base.

[0020] Furthermore, the base is provided with an arc-shaped groove around its circumference and is slidably connected to an arc-shaped slider, and the support rod is rotatably mounted on the arc-shaped slider.

[0021] When the base plate drives the support frame to rotate on the base, the arc-shaped slider can slide in the arc-shaped groove accordingly, ensuring that the support rod can support the support frame. Attached Figure Description

Detailed Implementation

[0024] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 5. The present invention provides a self-stabilizing temporary support device for precast bridge piers suitable for rapid construction, including a base 10, a support frame 20 and an adjustment mechanism 30. The support frame 20 can be adjusted to move on the base 10 by adjusting the adjustment mechanism 30, so as to quickly and efficiently support the bridge pier.

[0026] Specifically, as shown in Figures 1 to 3, the base 10 is an annular seat used for installation on the outer periphery of the bridge pier, and multiple sets of support frames 20 are arranged circumferentially on the base 10. The adjustment mechanism 30 includes sliders 31 and a driving member. Multiple sliders 31 are arranged circumferentially and movably mounted on the base 10, and are respectively connected to multiple sets of support frames 20. The driving member can drive the sliders 31 to move radially along the base 10.

[0027] The device is installed on the outside of the bridge pier, and the slider 31 is driven by a drive component to move on the base 10 and radially thereafter. This allows multiple sets of support frames 20 to move closer to the bridge pier, providing support from multiple directions. This method can quickly provide temporary support to the bridge pier from multiple directions, offering good support and being applicable to bridge piers of different specifications for reuse, thus reducing operating costs.

[0028] Specifically, the driving component includes a gear ring 32 and push blocks 33. The gear ring 32 is rotatably disposed within the base 10 and is concentric with the base and the pier. Multiple push blocks 33 are arranged circumferentially around the gear ring 32 and are movably disposed within the base, capable of moving along the tangent direction of the gear ring 32. Each push block 33 has a rack that meshes with the gear ring 32. The top of each push block 33 has an inclined groove 331. The two ends of the inclined groove 331 are located on different radial directions of the base 10. Multiple sliders 31 are slidably connected to the inclined grooves 331 of each push block 33, and the sliders 31 are limited to moving only along the radial direction of the base 10.

[0029] By driving the gear ring 32 to rotate, multiple push blocks 33 are driven to move along the tangential direction of the gear ring 32 in cooperation with the rack. The push blocks 33 can drive the slider 31 to move together through the inclined slide groove 331. Under the action of the inclined slide groove 331, the push blocks 33 move radially along the base 10, thereby driving the support frame 20 to move closer to or away from the central pier. In this embodiment, the driving component also includes a hydraulic motor 34 and a gear 35. The hydraulic motor 34 is disposed in the base 10 and connected to the gear 35, which meshes with the gear ring 32. The hydraulic motor 34 has the advantage of low-speed output of high torque, which can drive the gear 35 to rotate and drive the gear ring 32 to rotate, thereby driving the slider 31 and the support frame 20 to move.

[0030] Specifically, as shown in Figures 3 and 4, the base 10 is also provided with a support rod 21. One end of the support rod 21 is rotatably mounted on the base 10, and the other end is provided with a ratchet 211. The support frame 20 is provided with a support plate 22 on one side near the outer circumference of the base 10. The support plate 22 is provided with a plurality of movably connected ratchet teeth 221 along the vertical direction. The ratchet 211 cooperates with the ratchet teeth 221 and can rotate downward in one direction relative to the ratchet teeth 221.

[0031] The ratchet 211 at the end of the support rod 21 abuts against the support plate 22 on the outside of the support frame 20. When the support frame 20 is adjusted to move inward toward the base 10, the end of the support rod 21 with the ratchet 211 rotates downward under the action of gravity. At the same time, the ratchet 211 rotates on the ratchet tooth 221, which can then rotate downward to allow the ratchet 211 to pass. After the adjustment is completed, since the ratchet 211 cannot rotate in the opposite direction relative to the ratchet tooth 221, it can hold the support plate 22 and the support frame 20 together, thus improving the support effect on the bridge pier.

[0032] In this embodiment, the support frame 20 is provided in four sets, arranged in a cross shape, which can be applied to both circular and square bridge piers.

[0033] Specifically, as shown in Figures 3 and 5, it also includes an adjustment mechanism 2 40, wherein each of the two sets of opposing adjustment mechanisms 30 is provided with an adjustment mechanism 2 40, including a screw 41 and a gear 2 42. Two screws 41 are provided in parallel and are rotatably mounted on the slider 31. The threads of the two screws 41 are in the same direction. The gear 2 42 is located between the two screws 41 and meshes with the two screws 41 on both sides respectively. The gear 35 is connected to the bottom of the support frame 20 through a rotating shaft 43.

[0034] The two screws 41 are driven to rotate. When they rotate in the same direction, they drive the central gear 42 to move axially along the screws 41, thereby moving the support frame 20 via the shaft 43. This allows the two opposing support frames 20 to move closer to or further away from the pier, making it suitable for non-square rectangular piers. When the two screws 41 rotate in opposite directions, they drive the central gear 42 to rotate, thereby rotating the support frame 20 via the shaft 43. This adjusts the angle of the support frame, making it suitable for irregularly shaped piers. In practical use, the length of each member at the end of the support frame can be adjusted according to the shape of the outer wall of the pier to achieve the best support effect.

[0035] The support frame 20 has a base plate 23 at its bottom, which is fitted and slidably mounted on the base 10 and connected to the pivot 43 at its bottom. The base plate 23 is fitted and slidably mounted on the base, which facilitates the movement or rotation of the support frame 20 on the base 10.

[0036] As shown in Figure 1, the base 10 has a circumferential arc-shaped groove 11, and an arc-shaped slider 12 is slidably connected thereto. The support rod 21 is rotatably mounted on the arc-shaped slider 12, and the support plate 22 is connected to the arc-shaped slider 12 via a telescopic rod. When the base plate 23 drives the support frame 20 to rotate on the base 10, it can drive the arc-shaped slider 12 to slide correspondingly within the arc-shaped groove 11, ensuring that the support rod 21 can support the support frame 20.

[0037] The working principle of the aforementioned self-stabilizing temporary support device for precast bridge piers suitable for rapid construction is as follows: During use, the base 10 is installed on the outside of the bridge pier. A hydraulic motor 34 drives the gear 35 to rotate, which in turn drives the gear ring 32 to rotate, thereby moving the rack and push block 33. The inclined groove 331 on the push block 33 drives the slider 31 to move radially along the base 10, thus bringing the support frame 20 closer to the bridge pier and supporting the pier from multiple directions. When the support frame 20 moves towards the bridge pier, the ratchet 211 at the end of the support rod 21 rotates downwards, and the ratchet tooth 221 engages with the ratchet 211 to prevent it from rotating upwards, allowing the support rod 21 to hold the support frame 20 in place. For bridge piers of different shapes, the position or angle of the support frame can be adjusted by driving the screw 41. When driving the two screws 41 to rotate in the same direction, the second gear 42 moves axially along the screws 41, moving the support frame 20 to adjust its radial position. When driving the two screws 41 to rotate in opposite directions, the second gear 42 rotates, causing the support frame 20 to rotate and adjust its angle.

[0038] Using the aforementioned precast pier self-stabilizing temporary support device suitable for rapid construction, multiple sets of support frames can be moved simultaneously to provide temporary support for the pier from multiple directions quickly and efficiently. It not only has a good support effect, but is also applicable to piers of different specifications, can be reused, and reduces the cost of use.
