Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a guy rope hanging basket tensioning mechanism. Background Art

[0002] When constructing a cable-stayed bridge, it is necessary to first install the cable basket on the bearing platform, and then cast the main crossbeam. After the concrete reaches a certain strength, move the cable basket and install the tensioning mechanism, main truss mechanism and anchoring mechanism, and then install the cable between the tensioning structure and the main longitudinal beam for tensioning. After the cast diaphragm reaches a certain strength, transfer the tensioning end of the cable to the diaphragm.

[0003] For example, CN112942132A discloses a front-support composite hanging basket and its displacement method, which includes a hanging basket, a tensioning mechanism, a walking system, a positioning system and an anchoring system; the hanging basket is anchored on the cast beam section, and the tensioning mechanism connects the inclined cable with the hanging basket to form a front support. The walking system includes a triangular truss, a traction mechanism and a rear walking trolley, the traction mechanism lifts the front end of the hanging basket, the traction mechanism is provided with a force sensor and an automatic control system, and the rear walking trolley and the traction mechanism cooperate to realize the forward movement of the hanging basket; the positioning system is used to realize the initial positioning and adjustment function of the hanging basket, and the hanging basket, the triangular truss, the rear walking trolley and the positioning system are anchored on the cast beam section through the anchoring system; the above-mentioned front-support composite hanging basket and its displacement method do not adopt a hanging leg structure, which effectively avoids the space width limitation from the cable area to the edge of the beam, and the triangular truss participates in the force, which greatly reduces the mid-span deflection of the hanging basket in the width direction, ensuring the overall linear shape of the main beam.

[0004] However, most tensioning jacks are connected to pads through bolts. When replacing the installation positions of the tensioning jacks and the cable-stayed cables, the bolts need to be removed and installed one by one, which not only leads to a heavy labor burden on the construction workers, but also takes a long time, affecting the construction efficiency of the cable-stayed bridge.
