Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a cable-stayed bridge cutting and fixing device. Background Technology

[0002] A cable-stayed bridge is a type of bridge that uses stay cables to suspend the bridge deck. It is a structural system composed of a pressure-bearing tower, tension cables, and bending-resistant beams. Due to their large spans, ability to cross wide obstacles, and aesthetic appeal, cable-stayed bridges have developed rapidly both domestically and internationally. The stay cables are the main load-bearing components that directly transfer the weight of the main beam and bridge deck to the towers. Cutting and fixing devices are required during the production of stay cables.

[0003] Currently, in the process of bridge construction and maintenance, the cutting and fixing of stay cables is an important procedure. The traditional method is as follows: the workers place the stay cable to be cut on the cutting table, align the cutting part of the stay cable with the cutting disc, press the stay cable firmly, and drive the cutting disc to rotate at high speed through the cutting motor to achieve the purpose of cutting the stay cable. However, this method relies heavily on manual operation, which is not only inefficient, but also prone to safety risks: the cutting angle is easy to deviate and steel chips are easy to fly.

[0013] In a preferred embodiment, a support plate is fixedly connected to one side of the frame, and a cylinder a is fixedly installed at one end of the top of the L-shaped bracket, with the piston rod of the cylinder a fixedly connected to the support plate.

[0014] By adopting the above technical solution, the piston rod of cylinder a can extend and retract, thereby driving the support plate to move up and down, and thus adjusting the cutting height of the cutting tool.

[0015] In a preferred embodiment, a collecting plate is fixedly connected to the outside of the L-shaped bracket and below the roller frame, and a counterweight rod is fixedly connected to one end of the winding roller, with the counterweight rod placed inside the collecting plate.

[0016] By adopting the above technical solution, the counterweight rod inside the collection plate is removed, and the weight of the counterweight rod drives the protective rubber cloth to fall, thereby blocking the flying debris with the help of the protective rubber cloth.

[0017] In a preferred embodiment, the rotation shaft of the take-up roller extends to the outside of the roller frame and is fixedly connected to a throttle.

[0018] By adopting the above technical solution, the take-up roller can be rotated by using a throttle.

[0019] In a preferred embodiment, both clamping arms a and b are made of stainless steel, a controller is externally connected to the outer side of the base, and rubber pads are fixedly connected to the inner walls of both clamping arms a and b.

In this utility model, during the cutting process of the cable-stayed bridge, the protective rubber cloth on the take-up roller can be dropped, thereby blocking the flying debris with the help of the protective rubber cloth, which can improve the safety of the device. Furthermore, by rotating the take-up roller in the opposite direction, the protective rubber cloth can be wound up. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A cable-stayed bridge cutting and fixing device includes a base 1, with U-shaped frames 4 fixedly connected to both ends of the top of the base 1. Clamping arms a6 are provided inside the U-shaped frames 4. A clamping arm b7 is fixedly connected to the top of the base 1 and below the clamping arms a6. Two clips 16 are fixedly connected to both sides of the clamping arms b7. The clamping arms a6 have slots 15 inside that engage with the clips 16. When cutting the cable-stayed bridge, the operator can thread the cable between the two U-shaped frames 4 and lower the clamping arms a6 to engage the slots 15 and clips 16. Simultaneously, both clamping arms a6 and b7 are in contact with the surface of the cable-stayed bridge, thus preventing positional displacement of the cable during cutting and improving cutting accuracy. Furthermore, the use of clamping arms a6 and b7 allows the device to be used with cable-stayed bridges of different sizes, improving its applicability.

[0031] Specifically, an L-shaped bracket 2 is fixedly connected to the top of the base 1 and between the two U-shaped frames 4. A protective component is provided on the outside of the L-shaped bracket 2. The protective component includes a roller frame 13 fixedly connected to one end of the top of the L-shaped bracket 2. A take-up roller 12 is rotatably installed inside the roller frame 13. During the cutting of the cable-stayed bridge, the protective rubber cloth 8 on the take-up roller 12 can be dropped, thereby blocking the flying debris and improving the safety of the device. Reverse rotation of the take-up roller 12 can achieve the purpose of winding up the protective rubber cloth 8. The protective rubber cloth 8 is wrapped around the outside of the take-up roller 12. A cutting assembly is provided, comprising a frame 9 housed inside the L-shaped bracket 2. A drive motor 10 is fixedly mounted on the outside of the frame 9, and a cutting blade is rotatably mounted inside the frame 9. The output shaft of the drive motor 10 extends into the inside of the frame 9 and is fixedly connected to the rotation shaft of the cutting blade. The rotation of the output shaft of the drive motor 10 drives the cutting blade to rotate at high speed to achieve the purpose of cutting the cable-stayed bridge. A cylinder b5 is fixedly mounted on the top of each U-shaped frame 4. The piston rod of each cylinder b5 passes through the U-shaped frame 4 and is fixedly connected to the clamping arm a6. The use of the cylinder b5 provides the power source for lifting and lowering the clamping arm a6.

[0032] Specifically, a support plate 11 is fixedly connected to one side of the frame 9, and a cylinder a3 is fixedly installed at one end of the top of the L-shaped bracket 2. By extending and retracting the piston rod of the cylinder a3, the support plate 11 can be moved up and down, thereby adjusting the cutting height of the cutting tool. The piston rod of the cylinder a3 is fixedly connected to the support plate 11. A collecting plate 14 is fixedly connected to the outside of the L-shaped bracket 2 and below the roller frame 13. A counterweight rod is fixedly connected to one end of the take-up roller 12. The counterweight rod is placed inside the collecting plate 14. When the protective rubber cloth 8 is not needed, it can be rolled up and the counterweight rod is placed inside the collecting plate 14 to play a certain storage role. The rotation shaft of the take-up roller 12 extends to the outside of the roller frame 13 and is fixedly connected to a handle. The take-up roller 12 can be rotated by using the handle. Rubber pads are fixedly connected to the inner walls of the clamping arms a6 and b7. The rubber pads can prevent damage to the surface of the cable.

[0033] Working principle: First, the device is moved to the construction site, and the stay cable is threaded between two U-shaped frames 4. Then, the cylinder b5 is activated by the external controller, causing the clamping arm a6 to descend, engaging the slot 15 and the clamp 16 until both clamping arms a6 and b7 are in contact with the surface of the stay cable. This prevents the stay cable from shifting during cutting. Furthermore, the use of clamping arms a6 and b7 allows the device to be used with stay cables of different sizes, improving its applicability. Then, the collected... The counterweight rod inside plate 14 is removed, and its weight is used to pull the protective rubber cloth 8 down, thereby blocking the flying debris and improving the safety of the device. The control cylinder a3 is started to move the support plate 11 and the cutting tool above the cable. At the same time, the drive motor 10 is started, and the high-speed rotation of the cutting tool is used to cut the cable. After the cable is cut, the handle can be turned in the opposite direction to roll up the protective rubber cloth 8 and place the counterweight rod inside the collecting plate 14.
