Abstract
Machine is maintained to cable -stay bridge, including work platform, adjustable hanging wheel, adjustable top wheel, elevating system and adjustable balancing pole are constituteed. Adjustable hanging wheel fixes in work platform's upper end, and the lower extreme at work platform is fixed to adjustable top wheel, and the cable of cable -stay bridge passes adjustable hanging wheel, work platform and adjustable top wheel. Adjustable balancing pole is fixed in work platform lower extreme and adjustable top relative one side of wheel. Adjustable balancing pole is connected with another cable. The utility model discloses simple structure only needs on -the -spot simple equipment to be under construction, need not the road closure, and work platform climbs along the cable, and efficiency is high, moreover adjustable hanging wheel, adjustable top take turns and adjustable balancing pole with work platform fixing between two cables steadily, still can be under construction under the condition of strong wind.
Description
Technical field: the utility model relates to a kind of elevating mechanism, especially a kind of cable stayed bridge maintenance machine.
Background technology: cable stayed bridge is made up of suspension cable, king-post and girder, with some high-strength suspension cables by girder oblique pull on king-post, suspension cable makes girder be subject to a pressure and a flexibly mounted counter-force upwards, and this just makes the span ability of bridge greatly strengthen.Due to it, to have beam body size less, and the span ability of bridge is comparatively large, and the restriction by under-clearance and floor elevation is few, the feature that wind resisting stability is better than suspension bridge, is therefore widely adopted at present.Manned working platform is mainly hung on by crane by the maintenance work of current cable stayed bridge, execute man-hour requirement road closure, and efficiency is extremely low, is also subject to the impact of environmental factor, such as just can not construct in strong wind sky.
Utility model content: for above-mentioned the deficiencies in the prior art, the utility model provides that a kind of structure is simple, efficiency is high, not by the cable stayed bridge maintenance machine of large wind effect.
For achieving the above object, the technical solution adopted in the utility model is: cable stayed bridge maintenance machine, comprises working platform, adjustable hanging wheel, adjustable top wheel, elevating mechanism and adjustable and balancing bar composition.Adjustable hanging wheel is fixed on the upper end of working platform, and adjustable top wheel is fixed on working platform lower end, and the drag-line of cable stayed bridge is through adjustable hanging wheel, working platform and adjustable top wheel.Adjustable and balancing bar is fixed on working platform lower end and takes turns relative side with adjustable top.Adjustable and balancing bar is connected with another root drag-line.
Preferably, described elevating mechanism is self-lock type speed reducing machine and safety device.Wire rope connects self-lock type speed reducing machine by directive wheel, and safety rope is connected with safety device.
Preferably, described adjustable and balancing bar lower end is provided with stabilizer, and stabilizer can carry out adjusting position according to the distance of two drag-lines, and adjustable and balancing bar also can regulate length according to the distance of two drag-lines.
The utility model structure is simple, only need arrive on-the-spot simple assembling can construct, without the need to road closure, working platform climbs along drag-line, ultrahigh in efficiency, and adjustable hanging wheel, adjustable top wheel and adjustable and balancing bar are by working platform being fixed between two drag-lines steadily, still can construct under the condition of strong wind.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1: cable stayed bridge maintenance machine, comprise working platform 3, adjustable hanging wheel 2, adjustable top wheel 10, self-lock type speed reducing machine 5 and adjustable and balancing bar 8 form.Adjustable hanging wheel 2 is fixed on the upper end of working platform 3, and adjustable top wheel 10 is fixed on working platform 3 lower end, and the drag-line 1 of cable stayed bridge is through adjustable hanging wheel 2, working platform 3 and adjustable top wheel 10.Working platform 3 has been fixed on drag-line 1 by adjustable hanging wheel 2 and adjustable top wheel 10.Adjustable and balancing bar 8 is fixed on the side relative with adjustable top wheel 10, working platform 3 lower end.The lower end of adjustable and balancing bar 8 is provided with stabilizer 9, and drag-line is in the upper end of stabilizer 9 through adjustable and balancing bar 8, due to the gravity of stabilizer 9 self, makes adjustable and balancing bar 8 sagging, automatically finds the position on the drag-line of lower end accurately.Adjustable and balancing bar 8 can effectively prevent working platform 3 from overturning.Wire rope 4 connects self-lock type speed reducing machine 5 by directive wheel, and by manually riding self-lock type speed reducing machine 5, working platform 3 just can be driven to climb along drag-line 1, and safety rope 6 is connected with safety device 7, surprisingly disconnects to prevent wire rope 4 danger brought.
