Abstract

The utility model relates to a mechanism in the technical field of bridge and architecture construction, in particular to a pre-shaping mechanism of a linear unit main cable strand of a simulated suspension bridge. The pre-shaping mechanism comprises a riding wheel, a pressing wheel, a pedestal, a lifting frame, an adjusting screw, and an anti-dispersion block. The pre-shaping mechanism is characterized in that the riding wheel and the pressing wheel are arranged on two sides of the entire mechanism; the pedestal is arranged at the bottom for supporting the lifting frame; the adjusting screw is matched with the anti-dispersion block to form an arc-shaped structure; and the adjusting screw is arranged on the lifting frame. The pre-shaping mechanism can make the linear unit main cable stand bent during manufacture, so that the length of each wire in each strand is different from others to meet the requirement for the linear unit main cable strand of the novel simulated suspension bridge.

Description

The pre-shaping mechanism of unit strand imitating main cable linearity of suspension bridge
Technical field
The utility model relates to the mechanism in a kind of bridge and building manufacturing technology field, specifically is a kind of pre-shaping mechanism of unit strand imitating main cable linearity of suspension bridge.
Background technology
Unit strand is the composition of main push-towing rope in bridges such as suspension bridge, self-anchored suspension bridge and the building structure, is the stressed member of the bearing load of main push-towing rope in bridges such as suspension bridge, self-anchored suspension bridge and the building structure.The steel wire length that present unit strand is formed a bundle strand is all identical, on the bundle thigh of a segment distance at a certain distance at steel tendon thigh outer wrapping reinforced polyester band or finer wire.Along with the development of bridge technology, in bridges such as some suspension bridges, self-anchored suspension bridge and building structure, require main push-towing rope can carry out bending.Yet traditional unit strand owing to the complexity of main cable linear, makes that every steel wire is stressed and unbalanced, thereby makes indivedual steel wires stressed greater than other steel wire that the tensile strength that may surpass steel wire that has cause the existence of potential safety hazard behind imposed load.This just requires to form the relative length difference of every steel wire in the steel tendon thigh of main push-towing rope, to guarantee unit strand (or claiming strand) every steel wire stress equalization behind imposed load.
Summary of the invention
The utility model provides a kind of pre-shaping mechanism of unit strand imitating main cable linearity of suspension bridge at above-mentioned the deficiencies in the prior art.Can make unit strand imitating main cable linearity of suspension bridge just crooked when making, make the length difference of every steel wire in the bundle thigh, to adapt to the requirement of novel unit strand imitating main cable linearity of suspension bridge.
The utility model is achieved through the following technical solutions, the utility model comprises: support roller, pinch roller, base, jacking frame, adjusting screw(rod), anti-scattered, support roller and pinch roller are installed in the both sides of entire mechanism, base is positioned at the bottom support jacking frame, adjusting screw(rod) matches with anti-scattered and forms circular-arcly, and adjusting screw(rod) is located on the jacking frame.
Wherein support roller and pinch roller are installed in the both sides of entire mechanism, the centre-height when being used to adjust bundle and strand entering this mechanism, and base is positioned at the position that the bottom is used to control jacking frame, makes it that too much displacement not take place in the horizontal direction, but can move up and down.The jack that the moving up and down of jacking frame then relies on its bottom to install.
Compared with prior art, the utility model is eliminated the bundle thigh and should be crossed former thereby stress that produce indivedual steel wires in the bundle strand such as bend and concentrate, can make unit strand imitating main cable linearity of suspension bridge just crooked when making, make the length difference of bundle strand interior every steel wire, to adapt to the requirement of novel unit strand imitating main cable linearity of suspension bridge.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of symbols: support roller-1, pinch roller-2, base-3, jacking frame-4, adjusting screw(rod)-5, anti-scattered-6.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment has provided detailed embodiment being to implement under the prerequisite with technical solutions of the utility model, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: support roller 1, pinch roller 2, base 3, jacking frame 4, adjusting screw(rod) 5, anti-scattered 6, support roller 1 and pinch roller 2 are installed in the both sides of entire mechanism, base 3 is positioned at bottom support jacking frame 4, adjusting screw(rod) 5 matches with anti-scattered 6 and forms circular-arcly, and adjusting screw(rod) 5 is located on the jacking frame 4.Wherein support roller 1 and pinch roller 2 are installed in the both sides of entire mechanism, the centre-height when being used to adjust bundle and strand entering this mechanism, and base 3 is positioned at the position that the bottom is used to control jacking frame 4, makes it that too much displacement not take place in the horizontal direction, but can move up and down.The jack that the moving up and down of jacking frame 4 then relies on its bottom to install.
During use, all component is in place.Before bundle strand one-tenth dish, the adjusting screw(rod) 5 of this mechanism is regulated with anti-scattered 6, make its whole formation circular-arc (particular location is difference with every bundle burst different shape), (decide) at a certain distance, make bundle strand one-tenth circular-arc jacking frame 4 jack-up to restraint burst desired shape.This moment, the steel wire length of the bundle thigh lower floor in this mechanism was different with the length of upper strata steel wire.Wrapped with reinforced polyester band or finer wire on the bundle thigh then at assigned address.
Compared with prior art, present embodiment is eliminated the bundle thigh and should be crossed former thereby stress that produce indivedual steel wires in the bundle strand such as bend and concentrate, can make unit strand imitating main cable linearity of suspension bridge just crooked when making, make the length difference of bundle strand interior every steel wire, to adapt to the requirement of novel unit strand imitating main cable linearity of suspension bridge.
