First, which pre-tightens plate 110, is equipped with the first pulling eye 111, and second, which pre-tightens plate 120, is equipped with the second pulling eye 121;It is excellent Selection of land, the first pulling eye 111 and the second pulling eye 121 are symmetrical arranged, when carrying out pre-tightening cable work, the hook point of jack cucurbit It does not hang in the first pulling eye 111 and the second pulling eye 121.Preferably, first pre-tighten plate 110 be equipped with the first via hole 112, Second via hole 113, second, which pre-tightens plate 120, is equipped with third via hole 122, the 4th via hole 123.First via hole 112 with Third via hole 122 is symmetrical arranged, and the second via hole 113 and the 4th via hole 123 are symmetrical arranged.The setting of via hole can subtract The self weight of Light steel sheet, light when mobile, via hole is also used as hanging point and suspension centre uses.
Preferably, the inside of the first preload plate 110 is fixedly installed with the first interior lining panel, and the first interior lining panel is to pre-tighten with first The inside of the identical arc plate of 110 inner surface radian of plate, the second preload plate 120 is fixedly installed with the second interior lining panel, the second liner Plate is to pre-tighten the identical arc plate of 120 inner surface radian of plate with second.Preferably, the first interior lining panel and the second interior lining panel are soft Interior lining panel.When carrying out pre-tightening cable work, interior lining panel is contacted with main push-towing rope 400, prevents preload plate from directly contacting main push-towing rope 400, with Exempt to pre-tighten 400 wirerope zinc coat of dash-board injury main push-towing rope.In addition, interior lining panel can be substituted with protection gasket, carrying out pre-tightening cable work When, protection gasket is placed in and is pre-tightened between plate and main push-towing rope 400, in order to avoid pre-tighten 400 wirerope zinc coat of dash-board injury main push-towing rope.
Mobile mechanism includes a stringer 210, two idler wheels 220, two crossbeams 230, four rolling otic placode 250, two roller bearings 240, Stringer 210 is mounted on the first preload plate 110 by connector.The both ends of stringer 210 have been respectively fixedly connected with a crossbeam 230, the both ends of every crossbeam 230 are respectively welded an idler wheel otic placode 250, pass through roller bearing between idler wheel 220 and idler wheel otic placode 250 240 connections.Preferably, idler wheel 220 is soft rubber roll, in order to avoid the wirerope zinc coat of damage main push-towing rope 400.Idler wheel 220 The inward-facing smooth indentation of appearance make its walking surface cambered surface.In the preload cable work in a section, idler wheel 220 is along main push-towing rope 400, which carry out rolling, is moved to next section.
Connector includes screw rod 310, nut 340, spring 320, spring shim 330, and stringer 210 is equipped with a through-hole, spiral shell The lower end of bar 310 is fixedly mounted on the first preload plate 110, and screw rod 310 passes through the through-hole rear enclosure upper spring 320 on stringer 210, Spring shim 330 is placed on spring 320, and nut 340 is located at the top of spring shim 330, and nut 340 is tightened on screw rod 310. When jack cucurbit tenses, spring 320 is compressed, so that mobile mechanism adapts to the deformation of entire cable compacting machine structure.
Preload cable device provided by the utility model when in use, will pre-tighten cable device and hang on main push-towing rope 400, in inspection Whether liner plate or protection gasket are on the position contacted with main push-towing rope 400, in case the wirerope for pre-tightening dash-board injury main push-towing rope 400 is zinc-plated Layer.By the hook of jack cucurbit be hung on respectively the first preload plate 110 the first pulling eye 111 and second pre-tighten on plate 120 the In two pulling eyes 121, jack cucurbit is tightened, each plate that pre-tightens further is bonded with main push-towing rope 400, until first pre-tightens 110 bottom of plate The circular arc segment endpoint of medial surface is overlapped with the circular arc segment endpoint of the 4th preload 140 bottom inside face of plate, and main push-towing rope 400 just reaches pre- Sectional dimension as defined in tight cable operation, spring 320 is compressed at this time, so that mobile mechanism adapts to the deformation of entire cable compacting machine structure, Idler wheel 220 is loose at a distance from main push-towing rope 400, in case idler wheel 220 damages main push-towing rope 400.In the case where keeping pre-tightening cable power, installation Good tight cable steel band, then unclamping jack cucurbit is the preload cable work for completing a section on main push-towing rope 400.One section it is pre- After the completion of tight cable, in the state that jack cucurbit is loosened, cable compacting machine structure hangs on the vertical of mobile mechanism under the action of connector On beam 210, pre-tightened at this time there are gap between plate and 400 top surface of main push-towing rope, which can be when jack cucurbit be tightened because of spring 320 Gradually become smaller and finally disappeared by compression two.Plate manually is pre-tightened from the both sides of main push-towing rope 400 by pushing, it is auxiliary along being through to pre-tighten plate It helps the auxiliary ropes in hole mobile, pre-tightens strip and move the movement of idler wheel 220, since the effect of spring 320 makes idler wheel 220 in main push-towing rope It smooth movement and is reached at next preload cable section on 400.
The cable compacting machine structure of the utility model has multiple preload board groups at the size for pre-tightening plate is applicable to the outstanding of various cable diameters Cable bridge main push-towing rope manually pre-tightens cable, is particularly suitable for main push-towing rope 400 of the cable diameter greater than 1000mm and pre-tightens cable, and is structurally reasonable, pre-tightens plate It will not be damaged because of stress;And passing through test of many times, the transverse diameter of main push-towing rope 400, the perpendicular indexs such as diameter and out-of-roundness are equal after preload cable It can obtain good control;Cable device is pre-tightened compared to traditional sizing steel plate, makes to pre-tighten cable device tool by the way that mobile mechanism is arranged Standby mobile flexible, convenient feature, and movement of the soft idler wheel 220 of mobile mechanism on main push-towing rope 400 will not scratch main push-towing rope 400 The wire galvanization layer of top surface;In addition, can further improve the working efficiency that main rope of suspension bridge pre-tightens cable construction.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to In the utility model range claimed.
