Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a quick installation tool for box girder anchor plates. Background Technology

[0002] With the rapid development of infrastructure construction such as high-speed railways and bridges, precast box girders are a major component of bridge structures in railway construction. Among them, anchor plates, as key components in prestressed concrete, directly affect the safety and construction cycle of the entire bridge through their installation quality and efficiency. Box girder anchor plates play a crucial role in bridge structures, and their installation position, angle, and stability significantly impact the overall structural safety and durability. Currently, the hoisting and installation of box girder anchor plates typically involves using straps to bind the anchor plates. During installation, the anchor plates need to be aligned with the mounting holes on the box girder. However, the strap-lifting method lacks effective support for the anchor plates, making the process of adjusting their orientation to align with the mounting holes extremely inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a quick installation tool for box girder anchor plates.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A quick-installation fixture for box girder anchor plates includes a hook connecting plate, front and rear clamps located at the front and rear ends of the lower surface of the hook connecting plate. The top of the rear clamp is rotatably connected to the hook connecting plate in the front-rear direction. The height of the front clamp on the hook connecting plate is adjustable. The hook connecting plate provides connection to the lifting equipment, offering stable support for the entire fixture and ensuring its stable suspension. The front and rear clamps clamp the anchor plate from both directions, maintaining stability during lifting and preventing swaying or detachment, thus ensuring installation safety. The rear clamp can rotate relative to the hook connecting plate in the front-rear direction, allowing for angle adjustments during lifting. The adjustable height of the front clamp ensures precise alignment of the anchor plate with the mounting holes on the box girder. The coordinated action of the front and rear clamps provides a stable fulcrum and precise positioning for the lifting and installation of the anchor plate.

[0006] Furthermore, the front and rear grippers are at the same height in the initial state. By setting the front and rear grippers to be at the same height in the initial state, it is ensured that the front and rear grippers can simultaneously clamp the anchor plate in the initial state, maintaining a balance of clamping force and improving the stability of the anchor plate during hoisting and installation.

[0007] Furthermore, the tail end of the hook connecting plate is configured as an open-ended "U"-shaped structure, and the top end of the rear gripper is rotatably mounted in the cavity at the tail end of the hook connecting plate via a support shaft. The "U"-shaped structure design provides a stable mounting space for the rear gripper, and the support shaft allows the rear gripper to rotate inside the hook connecting plate, improving the adaptability and flexibility of the tooling.

[0008] Furthermore, a lifting rope is connected to the top of the front gripper, and the top of the lifting rope is suspended from the front end of the hook connecting plate via a suspension component. The height of the suspension component on the hook connecting plate is adjustable. By adjusting the height of the lifting rope and the suspension component, the position of the front gripper relative to the hook connecting plate can be adjusted, allowing the anchor plate to be quickly and accurately aligned with the mounting holes on the box girder, thereby improving installation efficiency.

[0009] Furthermore, the suspension component includes a threaded groove and a long bolt. The threaded groove is located at the front end of the hook connecting plate, and the long bolt is threaded into the threaded groove, with its bottom end passing through the groove to connect to the suspension rope. By rotating the long bolt, the height of the suspension rope can be easily adjusted, thereby adjusting the pitch angle of the front end of the front gripper, making the adjustment of the front gripper more convenient and precise.

[0010] Furthermore, a rope connecting plate is connected to the top of the lifting rope, and the rope connecting plate is rotatably mounted on the bottom of the long bolt. By setting the rope connecting plate, the connection between the lifting rope and the long bolt is made more secure, avoiding possible slippage or breakage of the lifting rope during the lifting process. This design ensures the smoothness and reliability of the lifting rope and improves the safety of the tooling.

[0011] Furthermore, a lifting lug is provided at the top of the hook connecting plate, and the lifting lug is located on the rear side of the middle position along the length of the hook connecting plate. By providing the lifting lug, the tooling can be easily lifted and moved by lifting equipment. The lifting lug being located on the rear side of the middle position along the length of the hook connecting plate helps to balance the center of gravity of the entire tooling and improves the stability during the lifting process.

[0012] Furthermore, both the front and rear grippers include a quadrilateral linkage structure. The bottom ends of the two lower sides of the quadrilateral linkage structure extend downwards and are connected to arc-shaped sleeves. The inner diameter of the arc-shaped sleeves is larger than the outer diameter of the part of the box girder anchor plate that is fitted by the arc-shaped sleeves. By setting the quadrilateral linkage structure, the stability and load-bearing capacity of the front and rear grippers are ensured. The design of the arc-shaped sleeves increases the contact area with the anchor plate, allowing the grippers to be tightly fitted onto the anchor plate, providing sufficient clamping force, and improving the stability and reliability of the clamping. The inner diameter of the arc-shaped sleeves is larger than the outer diameter of the fitted part, allowing the grippers to easily fit and fix the anchor plate, improving the stability and flexibility of the clamping.

[0013] This utility model has the following beneficial effects:

[0014] 1. By adjusting the height and pitch angle of the front jaws and the rotation connection design of the rear jaws, this tooling can quickly and accurately adapt to installation holes with different tilt angles, thereby greatly improving the installation efficiency of anchor plates.

[0015] 2. The quadrilateral linkage structure design of the front and rear grippers and the arc-shaped sleeve block can stably fit on the upper and lower surfaces of the anchor plate, ensuring that the anchor plate will not slip or fall off during hoisting and installation, thus improving the safety of the installation process.

[0016] 3. By rotating the long bolt to adjust the height of the front clamping jaws, the clamping angle of the anchor plate can be adjusted and the anchor plate can be installed, reducing labor intensity and operational difficulty. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 3As shown, a quick-installation fixture for box girder anchor plates includes a hook connecting plate 1, a front clamp 2 and a rear clamp 3 disposed at the front and rear ends of the lower surface of the hook connecting plate 1. The top of the rear clamp 3 is rotatably connected to the hook connecting plate 1 in the front-rear direction, and the height of the front clamp 2 on the hook connecting plate 1 is adjustable. By designing the hook connecting plate 1 as the main body for connection with the lifting equipment, and connecting it with the front clamp 2 and the rear clamp 3, stable support is provided. The front clamp and the rear clamp 3 are used to clamp the anchor plate, improving the stability of the anchor plate during the lifting process. The top of the rear clamp 3 is rotatably connected to the hook connecting plate 1 in the front-rear direction, and the height of the front clamp 2 is adjustable, allowing the fixture to adapt to the installation hole positions of the box girder anchor plates at different inclination angles. After clamping the anchor plate, the angle of the anchor plate can be adjusted, ensuring that the anchor plate is aligned with the installation hole on the box girder, improving installation accuracy and efficiency.

[0023] The front jaw 2 and the rear jaw 3 are at the same height in the initial state. This ensures that the anchor plate remains balanced during initial clamping, improving the clamping stability of the anchor plate and guaranteeing the safety of the installation operation.

[0024] The tail end of the hook connecting plate 1 is designed as an open-ended "U" shape, and the top of the rear gripper 3 is rotatably mounted in the cavity at the tail end of the hook connecting plate 1 via the support shaft 4. The "U" shape provides installation space for the rear gripper 3, allowing the rear gripper 3 to rotate around the support shaft 4 in the front-rear direction of the hook connecting plate 1, so that the rear gripper 3 can flexibly adjust its angle.

[0025] A suspension rope 5 is connected to the top of the front gripper 2. The top of the suspension rope 5 is suspended from the front end of the hook connecting plate 1 by a suspension component 6, and the height of the suspension component 6 on the hook connecting plate 1 is adjustable. By adjusting the height of the suspension component 6, the height of the suspension rope 5 can be adjusted, thereby achieving precise adjustment of the height of the front gripper 2.

[0026] The suspension component 6 includes a threaded groove 6.1 and a long bolt 6.2. The threaded groove 6.1 is located at the front end of the hook connecting plate 1. The long bolt 6.2 is threaded into the threaded groove 6.1, and its bottom end passes through the threaded groove 6.1 to connect to the lifting rope 5. By rotating the long bolt 6.2 and moving it up and down within the threaded groove 6.1, the height of the lifting rope 5 can be adjusted, thereby adjusting the pitch angle of the front end of the front gripper 2.

[0027] The top of the suspension rope 5 is connected to a suspension rope connecting plate 7, which is rotatably mounted on the bottom of the long bolt 6.2. The suspension rope connecting plate 7 ensures that the suspension rope 5 can be stably suspended on the long bolt 6.2, and allows the suspension rope 5 to be freely adjusted within a certain height by rotating its installation.

[0028] The top of the hook connecting plate 1 is provided with a lifting lug 8, which is located on the rear side of the middle position along the length of the hook connecting plate 1. The lifting lug 8 serves as the connection point for lifting the entire tooling, facilitating lifting and movement using lifting equipment. The lifting lug 8 is located on the rear side of the middle position along the length of the hook connecting plate 1 to ensure that the tooling is subjected to uniform and stable force during lifting.

[0029] Both the front gripper 2 and the rear gripper 3 include a quadrilateral connecting rod structure 9. The bottom ends of the two lower sides of the quadrilateral connecting rod structure 9 extend downwards and are connected to arc-shaped sleeve blocks 10. The inner diameter of the arc-shaped sleeve blocks 10 is larger than the outer diameter of the part of the box girder anchor plate that is fitted by the arc-shaped sleeve blocks 10. The quadrilateral connecting rod structure 9 is stable and deformable, serving as the main frame constituting the front gripper 2 and the rear gripper 3, ensuring the stability of the anchor plate clamping. The arc-shaped sleeve blocks 10 are used to actually clamp the anchor plate. The arc-shaped sleeve blocks 10, with their inner diameter larger than the outer diameter of the part of the box girder anchor plate that is fitted by the arc-shaped sleeve blocks 10, further achieve stable clamping and fixation of the anchor plate.

[0030] During the hoisting and installation of the anchor plate, the tooling is connected to the hoisting equipment via the lifting lug 8 at the top of the hook connecting plate 1. The front clamp 2 and the rear clamp 3 are stably clamped by the arc-shaped sleeve block 10 to achieve overall hoisting. The hoisting equipment lifts the tooling and the clamped anchor plate to the installation position on the box girder. According to the position of the installation hole on the box girder, the height of the front clamp 2 is adjusted. By rotating the position of the long bolt 6.2 in the threaded through groove 6.1, the pitch angle of the front end of the front clamp 2 is adjusted. During the height adjustment of the front clamp 2, the rear clamp 3 rotates in the front-rear direction of the hook connecting plate 1 to adjust the clamping angle of the anchor plate, so that the anchor plate is aligned with the installation hole on the box girder, making it easier to insert into the installation hole of the box girder, and then continue the next hoisting and installation of the anchor plate.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
