Abstract
The utility model discloses a movable angle adjusting frame which is hung on one end of a stay cable beam and comprises a bracing frame of a truss structure, wherein an operating platform is arranged on the upper portion of the bracing frame, a sliding orbit is arranged on the operating platform, and at least two calabash slings are arranged on the sliding orbit. The bracing frame is arranged on the orbit. The movable angle adjusting frame has the characteristics of convenient installation and disassembly, simple operation, safe use, accurate positioning, high working efficiency and the like, and greatly enriches the construction technique of a stay cable. Simultaneously, the adjusting frame has light weight, small generated load, repeatable use and good economical efficiency.
Description
Technical field
The utility model belongs to the suspension cable construction equipment of large and medium-sized cable stayed bridge, is specifically related to a kind of portable angle adjustment frame that the suspension cable beam-ends hangs that is used for.
Background technology
Suspension cable is hanged up construction and is mainly comprised bridge floor on the rope, exhibition rope, hangs and operation such as stretch-draw, hangs wherein that the operation technology content is the highest, difficulty and risk maximum.Hang branch tower end and hang with beam-ends and hang, consider the reliability and the safety of construction, suspension cable carries out the tower end earlier and hangs, and carries out beam-ends then and hangs.After the oblique tensile tower end hangs, the effect of the stretched wire power of being conducted oneself with dignity, in the suspension cable beam-ends distraction procedure, its anchored end is difficult to enter cable guide pipe (having angle between suspension cable anchored end and the cable guide pipe), simultaneously, knuckle must not appear in soft, the hard draw-gear part that beam-ends adopts, therefore, must carry out angle adjustment to beam-ends rope in the traction anchoring process, to make things convenient for traction construction; Existing all is to adopt single-point lifting adjustment to finish suspension cable to hang up.But the single-point lifting force is big, very easily suspension cable PE is produced and damages, and can not finish above-mentioned construction requirement for the suspension cable construction of large and medium-sized cable stayed bridge;
Take multiple spot to promote, but the lifting appliance that needs thus will roll up, the increase of equipment also can strengthen construction temporary load(ing) (also uneconomical), and this will produce very adverse effect to structure (steel case beam) and linear control.And do not have corresponding device thereof to address the above problem now as yet.
Summary of the invention
The purpose of this utility model is to provide a kind of suspension cable that is suitable for large and medium-sized cable stayed bridge that is exclusively used in to hang up the suspension cable beam-ends of construction and hang portable angle adjustment frame.To address the above problem.
The technical solution of the utility model is: the suspension cable beam-ends hangs portable angle adjustment frame, and it comprises the bracing frame of trussed construction, and operating platform is established on bracing frame top, and sliding rail is established in the operating platform top, and sliding rail is provided with at least two cucurbit suspenders.
Support frame as described above is located on the track.
Portable angle adjustment frame has peace and tears convenience, simple to operate, safe in utilization, characteristics such as the location is accurate, operating efficiency height open, has enriched stay cable construction technique to a great extent.Simultaneously, in light weight, little, reusable, the good economy performance of generation load of adjustment rack.

The specific embodiment
Present embodiment is used for the explanation to technical solutions of the utility model, and it is concrete structure that protection domain of the present utility model is not limited to down.
As shown in Figure 1, bracing frame 1 is the trussed construction that is formed by the rod member bolt; No longer this type of states trussed construction.Bracing frame 1 top setting operation platform 2, operating platform 2 shape as shown in Figure 2; Operating platform 2 tops, promptly sliding rail 3 is established at bracing frame 1 top; Sliding rail 3 is provided with at least two cucurbit suspenders 4; Establish cat ladder 5 on the bracing frame 1 and lead to operating platform 2 (as shown in Figure 3).As shown in Figure 3, bracing frame 1 has running roller 6, and running roller 6 is located on the track 7.Whole bracing frame 1 is located on the steel case beam 8.
The suspension cable beam-ends hangs construction as shown in Figure 4, in the time of near the suspension cable traction arrives beam-ends noose pipe, on rope, hoisting fixture is installed by certain spacing, and be connected with Chain block on the adjustment rack, upwards spur Chain block, make the angle and the noose pipe basically identical of beam-ends suspension cable, start jack traction suspension cable then and enter the noose pipe, constantly finely tune the drag-line angle in the distraction procedure by the folding and unfolding Chain block, until anchoring, when this skew cables hang finish after, adjustment rack integral body is drawn the installation site that moves to next root rope by hoist engine.This device can have been protected suspension cable and constructor's safety effectively, has guaranteed construction speed.
Claims (3)
1, a kind of suspension cable beam-ends hangs portable angle adjustment frame, and it comprises the bracing frame of trussed construction, it is characterized in that bracing frame top establishes operating platform, and sliding rail is established in the operating platform top, and sliding rail is provided with at least two cucurbit suspenders.
2, the suspension cable beam-ends hangs portable angle adjustment frame according to claim 1, it is characterized in that support frame as described above is located on the track.
