Description

Technical Field

[0001] This utility model belongs to the technical field of cable clamp installation construction of suspension bridge superstructure, and specifically relates to a cable clamp transport and installation trolley with upper and lower mating type. Background Technology

[0002] Cable clamps are cast steel components installed on the main cables of suspension bridges to secure the cables and connect them to the suspenders. The main structural forms of cable clamps include straddle-type and pin-hinged type, with pin-hinged cable clamps further divided into top-bottom and left-right matching types. A cable clamp typically consists of two semi-circular cast steel parts connected and securely installed on the main cable by high-strength bolts.

[0003] Currently, in the installation of main cable clamps for suspension bridges, cable cranes supported on the catenary gantry load-bearing cables are mainly used for the transportation and installation of the clamps. However, with the emergence of 2000m-class ultra-long span suspension bridges, the size and weight of the main cable clamps are constantly increasing. The original cable crane installation method is no longer suitable for the installation of large-tonnage clamps, and there are limitations and certain safety risks. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a vertically and horizontally aligned cable clamp transport and installation trolley. This trolley utilizes longitudinal and transverse rails to enable rapid adjustment of the upper and lower cable clamps, facilitating the installation of heavy-duty cable clamps and reducing safety risks.

[0005] The technical solution of this utility model is as follows: a trolley for transporting and installing cable clamps with upper and lower fittings, including a main cable, a lower truss, and an upper truss. The lower truss includes a steel frame one, with several linearly distributed traveling rollers inside the upper part of the steel frame one. A longitudinal slide rail is provided inside the lower part of the lower truss, and a lower half cable clamp is slidably mounted on the longitudinal slide rail. The upper truss includes a steel frame two, which is fixedly connected to the steel frame one. A transverse track is provided inside the upper part of the steel frame two, and an electric hoist is slidably mounted on the transverse track. The output end of the electric hoist is connected to a lifting rope, and the lower end of the lifting rope is connected to an upper half cable clamp. The upper half cable clamp is located directly above the lower half cable clamp inside the steel frame one, and the main cable is located between the upper half cable clamp and the lower half cable clamp.

[0006] The steel frame is equipped with multiple traction guide wheels at both the front and rear ends.

[0007] The transverse track is also equipped with transverse limiting wheels.

[0008] The steel frame is equipped with multiple lateral limiting rollers on both sides near the main cable.

[0009] The spatial angle between the longitudinal slide rail and the transverse track is 90°.

[0010] The lower roller surface of the traveling roller is in contact with the main cable.

[0011] The technical advantages of this utility model are as follows: 1. This utility model achieves rapid adjustment of the upper and lower half of the cable clamp through the longitudinal slide rail and the transverse rail, meeting the installation requirements of large-tonnage cable clamps and reducing safety risks. 2. This utility model ensures the lateral stability of the installation trolley by setting lateral limiting rollers.

[0012] The following will provide further explanation in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation Example 1

[0018] like Figures 1-4 As shown, a trolley for transporting and installing cable clamps with upper and lower sections includes a main cable 1, a lower truss 2, and an upper truss 3. The lower truss 2 includes a steel frame 21, with several linearly distributed traveling rollers 25 located at the top inside the steel frame 21. A longitudinal slide rail 24 is located at the bottom inside the lower truss 2, and a lower cable clamp 5 is slidably mounted on the longitudinal slide rail 24. The upper truss 3 includes a steel frame 31, which is fixedly connected to the steel frame 21. A transverse track 32 is located at the top inside the steel frame 31, and an electric hoist 35 is slidably mounted on the transverse track 32. A lifting rope 34 is connected to the output end of the electric hoist 35, and an upper cable clamp 4 is connected to the lower end of the lifting rope 34. The upper cable clamp 4 is located directly above the lower cable clamp 5 inside the steel frame 21, and the main cable 1 is located between the upper cable clamp 4 and the lower cable clamp 5.

[0019] In actual use, the lower truss 2 is equipped with traveling rollers 25 supporting the main cable 1 to meet the travel requirements of the trolley. A longitudinal slide rail 24 is installed below the lower truss 2. After the lower half of the cable clamp 5 is lifted to a certain height by a lifting device, it is placed into the longitudinal slide rail 24 and slides longitudinally to the middle position of the trolley. A second steel frame 31 is located on the outer side of the upper truss 3, and a transverse track 32 is arranged on the top of the second steel frame 31. An electric hoist 35 is installed on the transverse track 32. The upper half of the cable clamp 4 is lifted from the side of the main cable 1 by a lifting rope 34 via the electric hoist 35 and moved laterally into the second steel frame 31. After the upper half of the cable clamp 4 and the lower half of the cable clamp 5 are placed in position, the winch is started to pull the installation trolley to the installation position for installation. This invention achieves rapid adjustment of the upper and lower half of the cable clamps through the longitudinal and transverse slide rails, meeting the installation requirements of large-tonnage cable clamps and reducing safety risks.
