Hook-shaped lifting saddle and supporting structure of rail rope

Abstract

The invention discloses a hook-shaped lifting saddle and a supporting structure of a rail rope. The hook-shaped lifting saddle comprises a beam and a saddle body consisting of vertical beams positioned at two ends of the beam, wherein inwards hook-type parts are correspondingly arranged on the lower parts of the vertical beams; a rail rope saddle seat is arranged on the top of the hook-type parts; a lifting lug plate is arranged on the side face of the upper part of the saddle body; and channels for accommodating lifting rods are arranged along the vertical beams. By the hook-shaped lifting saddle, the structure of a ropeway conveying system is optimized and completed; the problem that a system can be converted only by a rope load lifting machine or other temporary lifting pieces is solved; a rope bridge is conveniently build and constructed; the working efficiency can be improved; and the construction progress is accelerated.

Description

technical field [0001] The invention is mainly used for erecting stiffening beams of suspension bridges, belongs to the device of a transportation system relying on steel wire ropes as rails, and specifically relates to a hook-shaped saddle and a supporting structure of rail cables. Background technique [0002] The suspension bridge cannot be erected without the cableway transportation system. The suspension saddle is an important part of the cableway transportation system. In this system, the suspension saddle is used as a supporting device for the wire rope track, and at the same time as a lifting point device for lifting the stiffening beam of the suspension bridge . [0003] China ZL200810107550.8 discloses a suspension saddle, the suspension saddle includes a door-shaped bracket, and the middle part of the door-shaped bracket is provided with a sling sleeve, which is used to be placed on the sling to stabilize the suspension saddle; at the lower end of the sling sleeve...

AI Technical Summary

Problems solved by technology

When this kind of saddle is used to erect the stiffening beam of the suspension bridge, since the saddle is directly pinned to the lower end of the sling, it occupies the hole where the sling is pinned to the steel truss girder, so that the saddle must be removed after the steel truss girder section is in place , after the beam transport trolley exits, the beam body can be lifted to complete the pinning of the sling; at the same time, the saddle does not have a working position for the jack, and it is necessary to install a cable crane or other temporary lifting points to meet the requirements of system conversion

In addition, when the rail trolley and the suspension saddle work together, a closed structure is formed, the rail trolley cannot be withdrawn conveniently, and it is not convenient to use the sling as the fulcrum of the lifting equipment
