Description

Technical Field

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

[0002] Cables are made of high-strength steel wires and are the main load-bearing components of cable-stayed bridges. They bear the weight of the entire bridge, including the weight of vehicles. Long-term exposure to loads can cause fatigue and strength failure.

[0003] Meanwhile, wind and rain erosion, solar radiation, and atmospheric moisture, salt, and oxygen can all have adverse effects on the cables. When the wire breakage rate is greater than 5%, the cables need to be replaced. The replacement of the cables is a high-altitude operation. During the construction process, the dragging of the cables can easily cause chaos on site, making it difficult to reel them in and posing a risk of falling. This poses a challenge to personnel safety and construction efficiency, and reduces overall safety. Utility Model Content

[0004] To overcome the challenges posed by cable dragging during construction, which easily leads to on-site chaos, difficulty in rewinding, and the risk of falling, thus posing a challenge to personnel safety and construction efficiency and reducing overall safety, this utility model provides a cable replacement device for cable-stayed bridges.

[0005] The technical solution is as follows: A cable-stayed bridge cable replacement device includes a vehicle body, a winding module, a guiding mechanism, a drive module, and a warning module; a winding module for winding the cable to be replaced is fixedly installed on the upper rear side of the vehicle body; a guiding mechanism for guiding the cable to slide down a set path is hinged to the upper front side of the vehicle body; a drive module for driving the winding and guiding actions is integrated inside the vehicle body; a warning module for work safety warning is installed on the outer wall of the front end of the vehicle body.

[0006] Furthermore, a hollow toothed ring is provided on the upper right side of the vehicle body; a towing hook is hinged to the front end of the vehicle body, and a loop-shaped buckle is passed through the lower end of the towing hook to increase the stability during towing and prevent it from falling off; and movable wheel sets are distributed along the lower edge of the vehicle body.

[0009] Furthermore, a push roller assembly with relative rotation is provided above the first guide tube. A push roller shaft is sleeved inside the push roller assembly, and a push motor is provided at each end of the push roller shaft. An X-shaped support arm is sleeved with the push roller assembly. A support opening is provided in the middle of the X-shaped support arm. A support hole rod is provided inside the support opening. A support column passes through the support hole rod. The support column is fixed to the outer arm surface of the first guide tube. A V-shaped spring damper is sleeved on the support hole rod. A locking tooth is vertically fixed to the inner wall of one side of the bottom end of the X-shaped support arm. A locking wheel with corresponding meshing locking teeth is provided on the symmetrically distributed connecting side of the bottom end of the X-shaped support arm.

[0012] The beneficial effects are: This utility model realizes the squeezing and rolling transmission mechanism through the X-shaped push roller group and the toothed roller electric assembly, so that the cable forms a directional constraint sliding in the guide tube, reducing the lateral space occupation of the construction area and effectively reducing the interference of multiple processes.

[0013] The guide tube tilt adjustment system, which consists of a double push rod adjustment assembly and a ball hinge, enables stepless adjustment within the elevation angle range. Combined with the moving wheel assembly and traction device, it can match the bridge tower anchor point displacement in real time during cable replacement, ensuring that the winding speed is synchronized with the cable release speed, thus achieving the effect of precise cable winding.

[0014] The three-color warning lights and alarms provide sound and light alerts to construction workers in the work area, reducing the occurrence of accidents. Warning labels enhance the visibility of the device and increase the effectiveness of risk warning. Attached Figure Description
