Background technology
Along with the fast development of Chinese national economy, the construction scale and the speed of striding suspension bridge of growing up of km level constantly increases, as the complete machine performance of the deck unit erection gantry of girder of suspension bridge lifting specialized equipment particularly on the cable walking manner demand urgently improving.The existing running gear that mainly contains winch formula, hydraulic pressure lift formula deck unit erection gantry of China adopts walking of set of wheels formula or all-hydraulic walking all can not realize walking voluntarily on cable, all need the traction of winch, equipment such as traction jack etc. moving on the cable and manually to carry, dismantle, install auxiliary such as folder cable anchor ear in the high-altitude repeatedly and finish complete machine fixing on main push-towing rope, cause cost to increase claim for eot like this and have danger.
Summary of the invention
Above shortcoming in view of prior art, the purpose of this invention is to provide a kind of self-propelled hydraulic pressure deck unit erection gantry, make it to overcome the deficiency of prior art, the realization deck unit erection gantry just can realize that self walks on the cable under the condition that need not auxiliaries such as extra tractor equipment and the dismounting of artificial high-altitude fortune folder cable anchor ear.
The objective of the invention is to realize by following means.
Self-propelled hydraulic pressure deck unit erection gantry, formed by power system, control system and mechanical actuating mechanism, described mechanical actuating mechanism mainly by main couple (100), be installed in the main couple two ends walking voluntarily system (210 and 220), be installed in the cover of two on main couple hydraulic lift system (310 and 320), shoulder pole girder (400) constitutes; Main couple and shoulder pole girder all adopt the variable-length structure; Described hydraulic lift system (310 and 320) is made up of continuous lifting jack (311), steel strand guides (312), the steel strand (510) that return rope device (313) and be connected shoulder pole girder.Adopt aforesaid way, the present invention has following advantage:
1) need not extra tractor equipment and the dismounting of artificial high-altitude and transport walking voluntarily on realization such as the auxiliary that presss from both sides the cable anchor ear cable.
2) guarantee under the prerequisite of complete machine structure safety, only change few parts and just lift applicable to the suspension bridge steel case beam in different cables footpath.
3) guarantee to adapt to by the described interlude of changing different length under the prerequisite of complete machine structure safety the suspension bridge of different main push-towing rope spacings.
4) the deck unit erection gantry master control system can be to walking walking that system, hydraulic lift system etc. carry out manually voluntarily, automatic guidance is realized deck unit erection gantry optional position on main push-towing rope and fixed point lifting.
In sum, self-propelled deck unit erection gantry of the present invention has on the cable walking, advantages such as the speed of travel is fast, adaptive capacity is strong, anti-slide performance is strong, safety height voluntarily, applicable to setting up of different suspension bridges.

The specific embodiment
Below in conjunction with drawings and Examples structure of the present invention is described further.
As shown in Figure 1, the present invention mainly by main couple 100, be installed in the main couple two ends two cover walkings voluntarily system 210 and 220, be installed in mechanics that two on main couple cover hydraulic lift system 310 and 320, shoulder pole girder 400 form and power system and control system and form.Among the figure 010 with 020 for the parallel main push-towing rope that sets up, 000 for waiting to hang steel case beam.Walking system 210 and 220 is supported on the main push-towing rope, and main couple and two walking systems are hinged, like this complete machine just can by walking voluntarily system on main push-towing rope, move.
Main couple and shoulder pole girder all adopt the variable-length structure, shown in Figure 2: main couple 100 is by interlude 110 and place the insertion section 120 and 130 of interlude to constitute slidably, after the distance of the cable between two main push-towing ropes is determined, the removable section of inserting also adopts conventional mode that the section of insertion and interlude are fixed, with the main couple length that obtains to match with decided cable distance.
Same situation and purposes also are fit to the design of shoulder pole girder, as seen from Figure 3, shoulder pole girder 400 by intermediate beam 410 and place slidably the intermediate beam termination end carriage 420 and 430 constitute, end carriage 420 is inserted in the intermediate beam, can be according to the extension elongation of cable, and by usual manner fixed end beam and intermediate beam apart from the control end carriage.
Two cover hydraulic lift systems 310 and 320 are arranged on the main couple two ends, adopt synchronous stepping to promote jack continuously.Fig. 4 is the External view of hydraulic lift system, and elevator system is made up of the steel strand 510 of continuous lifting jack 311, steel strand guides 312, time rope device 313 and connection shoulder pole girder continuously.Suspender on the described hydraulic lift system connects with described shoulder pole girder 400 by bearing pin.Shoulder pole girder is provided with hanger, respectively with the suspender on the described hydraulic lift system, wait that the suspension centre that hangs steel case beam is connected.
The installation that can be seen self-propelled hydraulic pressure deck unit erection gantry main couple of the present invention and walking system by Fig. 5 concerns that main couple 100, walking be system 210 voluntarily, main push-towing rope 010.In the present embodiment, walking system 210 is made of supporting leg 211 and 212, slip end carriage (213), walker 214, walker top is hinged by adapter shaft 215 and deck unit erection gantry main couple 100, and the walker bottom is supported on the main push-towing rope 010 by automatic folder cable device 216 and 217; Walker links to each other by walking oil cylinder 218 with the slip end carriage and can move on the slip end carriage.Fig. 6 is the site plan after once moving.
Embodiment described here is in order to help reader understanding's principle of the present invention, should to be understood that the protection domain of inventing is not limited to such special statement and embodiment.Everyly make various possible being equal to according to foregoing description and replace or change, all be considered to belong to the protection domain of claim of the present invention.
