Problems solved by technology

Due to the low density of the strands wound by this method, it will cause the strands to be scattered and affect the use quality and construction convenience of the strands
[0004] 2. The structure is complex, and the operation of receiving and releasing the cable is inconvenient: it is necessary to reduce and enlarge the diameter of the reel ...

Embodiment Construction

[0024] see Figure 1~3 , The bridge and the structure use the cable bodiless type retractable cable mechanism, which is mainly composed of a turntable 1, a support rod or a support piece 2, a push-pull rod 3, an adjustment rod 4, an adjustment nut 5, a support 6 and a column 7 and so on.

[0025] The column 7 is arranged upwardly at the center of the turntable 1 . The support 6 is arranged on the top of the column 7, and the lower end of the adjusting rod 4 is screwed with the support 6, as Figure 4 . There are many supporting rods or supporting pieces 2 (six in the figure), which are evenly distributed on the periphery of the column 6. The upper end of 4 is hinged.

[0026] working principle:

[0027] When winding, the adjusting rod is moved up and down through the thread, and the push-pull rod is pushed, and the push-pull rod pushes the support rod to rotate outward around the hinge point at its lower end, so that the inclination angle between the support rod or the sup...

Abstract

The invention discloses a cable demould folding-unfolding device used to fold and unfold the cable demould package of bridge. It is characterized in that: it comprises a rotation disc (1), a support rod or support plate (2), a pushing rod (3), an adjusting rod (4), a base (6), and an upright post (7). Wherein, said upright post (7) is arranged at the center of rotation disc (1); the base (6) is arranged at the top of upright post (7); the lower end of adjusting rod (4) is movably connected to the base (6); there are several support rods or plates (2) uniformly distributed around the upright post (6), whose lower end is hinged to the outer edge of rotation disc (1) and upper end is hinged to one end of pushing rod (3); another end of pushing rod (3) is hinged to the upper end of adjusting rod (4). The invention has simple operation, high cable quality, and high folded cable intensity, while it can automatically arrange wires in unfolding process.

Description

Technical field: [0001] The invention relates to a cable bodiless retracting and releasing mechanism for bridges and structures. It is mainly used for receiving and releasing cables in the tire-free packaging of bridge cables. It belongs to the technical field of bridge construction. Background technique: [0002] Before the present invention was made, the cable retracting and releasing mechanism currently used for bridge cable bodiless packaging and cable releasing was a reel structure. It is mainly composed of a rotary turntable and a reel vertically set up on the turntable. The upper and lower diameters of the reels are the same. The principle of receiving and releasing the cable is: when receiving the cable, turn the turntable to wind up the parallel steel wire strands on the reel, then reduce the diameter of the reel so that the outer wall of the reel is separated from the strand ring, and then pack the strands out of the body . It mainly has the following deficien...
