Problems solved by technology
The structure of the device is complicated, the cost is high, and it takes up a lot of space on the beam surface. During the process of hanging the cable, it affects the construction of other processes on the beam surface.
This device is only suitable for the hanging of super-long cables, and it cannot construct cable-stayed cables with a small transverse distance from the edge of the beam. The maneuverability is poor, the limitations are large, and the scope of application is small.

Embodiment Construction
[0021] This embodiment is a follow-up beam-face inclined stay cable stay-cable guide hole entry guide device, a follow-up beam-surface stay cable stay-cable guide hole entry guide device, which includes: A-shaped bracket 1, sash beam 2, Traveling longitudinal beam 3, mobile lifting point 4 and lifting system 5.
[0022] like figure 1 As shown, there are four A-shaped brackets 1, which are respectively welded with I-beams, and are all composed of inclined columns 101 and beams 102. There are two sash beams 2 that all adopt box-shaped cross-sections, and each sash The beams 2 are all arranged on the tops of the two A-shaped brackets 1 to form the main load-bearing system. The top of each sash beam 2 is provided with a bolt hole for connecting the running stringer 3, and the running stringer 3 passes through the bolt holes. The holes are erected on two sash beams 2, and the running longitudinal beam 3 is processed by two I-shaped steel rails, leaving a gap of 8cm to 10cm between...

The invention discloses a servo-type beam surface stay cable pulling-into-hole guide device and a construction method thereof. The servo-type beam surface stay cable pulling-into-hole guide device and the construction method thereof are used for beam surface hanging construction of a stay cable. The servo-type beam surface stay cable pulling-into-hole guide device is mainly composed of A-shaped supports, frame cross beams, a walking longitudinal beam, a movable lifting point, a lifting system and the like. After tower-end hanging of the stay cable is completed, the servo-type beam surface stay cable pulling-into-hole guide device lifts the stay cable and works in cooperation with a pulling system on the bottom of a cable guide pipe to complete beam-end hanging of the stay cable. The servo-type beam surface stay cable pulling-into-hole guide device has the advantages of being large in bearing capacity, stable in structure, light in self-weight, high in working efficiency, high in adjustability, wide in application range, convenient to disassemble and assemble and the like, improves the stay cable beam surface hanging construction process and accelerates the stay cable beam surface hanging construction progress.
Description
technical field [0001] The invention belongs to the cable-stayed cable-hanging construction technology, and in particular relates to a beam surface cable-stayed cable-guide hole-entry guide device and a construction method. Background technique [0002] In recent years, with the deepening of statically indeterminate structure theory, finite element simulation technology, model tests and bridge design calculations, my country's bridges have developed towards complex and long-span directions, especially long-span cable-stayed bridges have developed rapidly. The cable-stayed cable is an important force-transmitting component between the cable tower and the girder body, and is an important part of the cable-stayed bridge. Cable-stayed construction mainly includes processes such as cable transportation, cable extension, sling, hanging and tensioning. Among them, the construction process of cable-stayed beam surface hanging is high in technical content, difficult and long constru...
