Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Example 1:
as shown in fig. 1, in this embodiment, a cable clamp boom installation device for a cable bridge includes a main tower, a main cable disposed on the main tower, and an operation frame slidably disposed on the main cable, wherein two rollers are connected to the upper side of the main cable in a rolling manner, the operation frame is connected to the lower side of the rollers, a locking device connected to the main cable is disposed on the operation frame, and a chain block connected to the operation frame through a chain block pull line is disposed on the main tower.
After the main cable is installed, the idler wheel is installed above the main cable, the operation frame is connected with the idler wheel and installed below the main cable, and the hand block on the main tower can be used for pulling the operation frame at the lower part to the position near the top of the main tower through the hand block pulling rope, so that the working personnel in the operation frame can construct the cable clamp and the hanging rod. And after the construction is finished, moving the operation frame to a low position. This structure can utilize the main push-towing rope structure of adorning, need not set up extra catwalk, is favorable to reducing construction cost, reduces the material waste. And this scheme simple structure conveniently prepares at the job site fast, and after finishing using, the dismantlement that can not have the destruction avoids the structure or the device itself of having been under construction impaired to can used repeatedly. The both sides of gyro wheel are provided with the gyro wheel backup pad, are provided with the gyro wheel pivot between the gyro wheel backup pad, and the gyro wheel rotates and sets up in the gyro wheel pivot. The roller supporting plate is detachably connected with the operation frame. Therefore, the operation frame is convenient to disassemble and assemble, and the influence on the constructed main cable when the operation frame is disassembled and assembled is avoided.
The main cable is limited between the two roller supporting plates, so that the safety performance can be improved, and the operation frame is prevented from being completely separated from the main cable.
