[0001] This utility model belongs to the field of cable-stayed bridge construction technology, and in particular relates to an anti-overturning cable-stayed cable hanging process deployment trolley. Background Technology

[0002] In the construction of cable-stayed bridges, the installation of the cable-stayed cables is a crucial step, directly impacting the structural safety and construction efficiency of the bridge in its later use. During construction, the cables are typically transported to the construction site in coils. Workers then perform an uncoiling operation on-site, securing one end of the cable to an uncoiling trolley. The coiled cables are then gradually unwound to facilitate subsequent hoisting. Traditional trolleys are prone to causing the cables to slip, sway, or shift laterally during transportation or operation, affecting construction safety. Utility Model Content

[0003] In view of this, the present invention aims to provide an anti-overturning cable-stayed cable-hanging trolley for the cable-stayed cable-hanging process, so as to improve the stability of the trolley during construction.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A locking trolley for anti-overturning cable-stayed cable installation process, including...

[0006] A cargo platform, on which at least one fixed module is connected to the cable-stayed cable;

[0007] Multiple auxiliary units are fixed to the corners of the loading platform, and the fixing module is placed within the area surrounded by the connecting lines of the multiple auxiliary units. Each auxiliary unit includes a fixing seat and a clamping plate. The fixing seat is U-shaped and its opening faces the upper or lower surface of the loading platform, so that the fixing seat and the loading platform surround to form a line-passing space. The clamping plate is placed in the line-passing space, and ball bearings are embedded on the clamping plate and the upper or lower surface of the loading platform.

[0008] The guide cable passes through the cable passage space, and the clamp can press firmly against the cable.

[0009] Furthermore, the fixing seat has two first limiting surfaces arranged opposite to each other, and the clamping plate is provided with second limiting surfaces on both sides, with the first limiting surfaces and the second limiting surfaces fitting together.

[0010] Furthermore, the surface of the clamp plate opposite to the loading platform is arc-shaped.

[0011] Furthermore, the clamping plate is rotatably connected to a screw, and the fixing seat is screwed to the screw.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] The anti-overturning cable-stayed cable hanging process described in this application includes a loading platform 1, on which at least one fixing module 2 connected to the cable-stayed cable is provided.

[0033] Multiple auxiliary units 3 are fixed to the corners of the loading platform 1, and the fixing module 2 is placed within the area surrounded by the line connecting the multiple auxiliary units 3. Each auxiliary unit 3 includes a fixing seat 31 and a clamping plate 32. The fixing seat 31 is U-shaped and its opening faces the upper or lower surface of the loading platform 1, so that the fixing seat 31 and the loading platform 1 surround to form a line-passing space 312. The clamping plate 32 is placed in the line-passing space 312. Ball bearings are embedded on the clamping plate 32 and the upper or lower surface of the loading platform 1.

[0034] The guide cable passes through the cable passage space 312, and the clamp 32 can press tightly against the cable.

[0035] During operation, the guide cable is fixed along the preset movement path of the trolley. Both ends of the guide cable can be tied to supports, anchor piles, etc. The loading platform 1 is connected to the cable via auxiliary units 3 and clamping plates 32. Since there are multiple sets of auxiliary units 3 distributed around the fixed module 2, when the trolley receives deflection or torsional stress from the stay cable, the stress can be transferred to the cable, thus helping the trolley maintain its posture and reducing the risk of deviation or overturning. The ball bearings on the clamping plates 32 and loading platform 1 generally move along the length of the cable, reducing friction between the trolley and the cable and extending the equipment's service life.

[0036] The fixed base 31 has two opposing first limiting surfaces 311, and the clamping plate 32 has second limiting surfaces 321 on both sides. The first limiting surfaces 311 and the second limiting surfaces 321 fit together, thereby providing guidance for the movement of the clamping plate 32 through the cooperation of the first limiting surfaces 311 and the second limiting surfaces 321. The first limiting surfaces 311 are located on both sides of the cable passage space 312. The fixed base 31 also has a through hole, and a threaded seat is inserted into the through hole and fixed to the inner wall of the through hole. Optionally, the through hole and the threaded seat are connected by a key block. A screw 34 is screwed to the fixed base 31 through a threaded sleeve 313, and the bottom end of the screw 34 is rotatably connected to the clamping plate 32. The top end of the screw 34 has a square shaft, and a handle 33 can be sleeved on the square shaft to drive the screw 34 to rotate, thereby making the clamping plate 32 press tightly against the cable. The surface of the clamp 32 opposite to the loading platform 1 is arc-shaped, so that the outer surface of the cable can fit with the arc-shaped surface of the clamp 32, thereby improving the reliability of the fit between the cable and the clamp 32.

[0037] The fixing module 2 includes a carrying plate 21, with fixing tiles 23 fixed at both ends along the direction of the trolley's movement. The fixing tiles 23 are arc-shaped, and their ends are connected to the sides of the carrying plate 21 perpendicular to the direction of the trolley's movement. The end of the stay cable can pass through the fixing tiles 23. During operation, the stay cable passes through the space between the fixing tiles 23 and the carrying plate 21. A clamp is then fixed to the anchor head of the stay cable to prevent it from slipping off the trolley during operation. The coiled stay cable is then unrolled by pulling the trolley. The fixing module 2 also includes an elastic rope 24, with both ends connected to the sides of the carrying plate 21 perpendicular to the direction of the trolley's movement. The elastic rope 24 rests on the end of the stay cable to reduce vibration during trolley movement. Multiple anti-slip grooves 21112 are formed on the upper surface of the carrying plate 21 to prevent the anchor head of the stay cable from separating from the carrying plate 21.

[0038] The loading platform 1 has a groove 12 along the direction of the trolley's movement. Slider blocks 22 are provided on both sides of the loading plate 21, and the sliders 22 extend into the groove 12. In this embodiment, there are two sets of fixing modules 2. The operator can adjust the position of the fixing unit 25 along the length of the groove 12 according to the specifications and design requirements of the cable-stayed bridge, maintaining a preset distance between the two fixing modules 2. Fixing units 25 are also provided on both sides of the loading plate 21. Each fixing unit 25 includes a bolt 251 and a clamping block 252. The bolt 251 passes through the loading plate 21 and the groove 12 and connects to the clamping block 252. In this embodiment, the clamping block 252 is placed below the loading platform 1, and the length of the clamping block 252 is greater than the width of the groove 12, so that both ends of the clamping block 252 can abut against the edge of the groove 12. Fixing portions extend outward from both sides of the loading plate 21, and through holes are provided on the fixing portions. The bolts 251 pass through the fixing portions and are screwed to the clamping blocks 252. After the operator determines the position of the fixing module 2 along the length of the slide 12, the fixing module 2 is fixed to the loading platform 1 by bolts 251 and clamping blocks 252. The depth of the slide 12 is greater than the thickness of the slider 22.

[0039] 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.
