Description
Technical field
The utility model belongs to bridging equipment technical field, more particularly, to a kind of anti-idler wheel mechanism.
Background technique
With the needs of economic construction of China, the rapid development of China Expressway, bridge construction is also more and more, construction
Section is increasingly longer, and construction environment becomes increasingly complex, in this regard, Bridge Erector is as the large special equipment in construction of the highway, to it
Performance requirement is also higher and higher.Currently, when needing via hole operation in the construction process, need to rely on other ancillary equipments, by frame
Bridge machine is moved, and is taken time and effort, and working efficiency is low.
Summary of the invention
The utility model mainly solves technical problem present in the above-mentioned prior art, provides a kind of anti-idler wheel mechanism.
Above technical problems of the utility model are mainly solved by the following technical scheme: a kind of anti-roller machine
Structure, between the two main supporting legs and girder of Bridge Erector, including support frame, the abdomen of support frame as described above are equipped with two rows of directive wheels,
The directive wheel includes driving wheel and driven wheel, is toothed around on the directive wheel and tooth socket, the driving wheel and driven wheel it
Between connected by gear, the side of support frame as described above is equipped with driving motor, and the output end of the driving motor is connected with shaft, institute
It states shaft to connect with two driving wheels, the side wall of support frame as described above is equipped with square hole, is equipped with idler wheel in the square hole.
Preferably, the surface of support frame as described above is equipped with several staggered reinforcing ribs, improves the rigidity of anti-idler wheel mechanism.
The utility model has the advantages that the utility model using gear drive, and driving motor drives shaft rotation,
It is connected with the rotating shaft driving wheel rotation to drive, driving wheel drives driven wheel to rotate by gear, and girder is placed on directive wheel
On, with the rotation of directive wheel realize it is longitudinal be moved forward and backward, can be with by anti-idler wheel mechanism when lifting middle supporting leg and front leg strut
The position of supporting leg and front leg strut in adjusting, and bridge formation can be allowed with support girder, the total weight of stringer purlin vehicle and trolley
Machine cross without counterweight high efficiency across not needing additional auxiliary machinery and helped, fulfiled assignment；Rolling on support frame side wall
Wheel reduces frictional force when girder or mobile two main supporting legs, convenient for advancing, improves working efficiency.
Detailed description of the invention

Fig. 2 is a kind of side structure schematic view of the utility model.
In figure: 1, support frame；2, driving wheel；3, driven wheel；4, the gear teeth；5, tooth socket；6, gear；7, driving motor；8, turn
Axis；9, square hole；10, idler wheel.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: a kind of anti-idler wheel mechanism, as Figure 1-Figure 2, and between the two main supporting legs and girder of Bridge Erector, packet
Support frame is included, the abdomen of support frame as described above is equipped with two rows of directive wheels, and the directive wheel includes driving wheel and driven wheel, the guiding
It is toothed around on wheel and tooth socket, is connected between the driving wheel and driven wheel by gear, the side of support frame as described above, which is equipped with, drives
Dynamic motor, the output end of the driving motor are connected with shaft, and the shaft is connect with two driving wheels, the side of support frame as described above
Wall is equipped with square hole, is equipped with idler wheel in the square hole.
The surface of support frame as described above is equipped with several staggered reinforcing ribs, improves the rigidity of anti-idler wheel mechanism.
When work, anti-idler wheel mechanism in starting on supporting leg and front leg strut, driving motor drives shaft rotation, to drive
It is connected with the rotating shaft driving wheel rotation, driving wheel drives driven wheel rotation by gear, and girder is placed on directive wheel, with leading
Longitudinal be moved forward and backward is realized to the rotation of wheel；When lifting middle supporting leg, anti-idler wheel mechanism in starting on supporting leg, supporting leg in adjusting
Position；When lifting front leg strut, starts the anti-idler wheel mechanism on front leg strut, adjust the position of front leg strut.Cross across when, prop tail
Supporting leg, the distance between supporting leg and tail in adjustment, then packs up tail supporting leg, starts anti-roller driving mechanism, and girder can protract,
Stop stretching out when preceding interim supporting leg arrival front bent cap outer end suitable location, jacks up tail supporting leg, simultaneously with front leg strut by middle supporting leg
Hold together, then reduce front leg strut, while screwing out interim supporting leg, interim supporting leg is implemented on bent cap before making, and continuing retraction front leg strut makes
Empty, then start front leg strut on anti-idler wheel mechanism, move ahead together with cross moving track, reach front bent cap suitable location
After stop, stretching out front leg strut and be allowed to implement on bent cap, until interim supporting leg empties, pack up tail supporting leg, before starting, middle supporting leg
Anti- idler wheel mechanism makes girder extension until suitable location, finally locks anti-idler wheel and girder, and across hole operation is completed.Entirely across hole
Without being laid with dedicated track, it is not necessarily to tail balancing weight, all autonomous completion.
Finally it is pointed out that above embodiments are only the more representational examples of the utility model.Obviously, this is practical new
Type is not limited to the above embodiments, and acceptable there are many deformations.All foundation the technical essence of the utility model are to above embodiments
Made any simple modification, equivalent change and modification are considered as belonging to the protection scope of the utility model.
