The utility model discloses a set up fixed guide, mobile rail, first group leading wheel, second group leading wheel and bearing wheel, when hoist adjustment position, can ensure the hoist and adjust position remaining stable nature of in -process, the security of ensureing to lift by crane the in -process under the effect that first group leading wheel, second group leading wheel were taken turns with the bearing like this.
Description
Technical field
The utility model relates to mechanical equipment technical field, particularly relates to a kind of gauntry crane traveling gear.
Background technology
Gauntry crane is that horizontal bridge frame is arranged on a kind of crane span structure type hoisting crane two supporting legs being formed door frame shape.This hoisting crane runs on ground rail, mainly carries out carrying and installation exercise with yard, dock, power station, harbour and railway stock in the open and other places.
The lifting mechanism of gauntry crane, wheeling mechanism and portal structure are substantially identical with crane in bridge type.Because span is large, crane travel mechanism adopts type of drive respectively mostly, increases resistance, even have an accident to prevent hoisting crane from producing crooked operation.The crane carriage of gauntry crane runs on crane span structure, and some crane carriages are exactly a jib-type crane.Crane span structure can be that two ends are without cantilever; Also can be that one end has cantilever or two ends to have cantilever, to expand scope of work.There is supporting leg semi portal brdige crane crane span structure one end, and the other end, without supporting leg, directly runs on high stand.
The tire traveling gear that existing gauntry crane generally adopts, such walking structure in the process of walking stationarity is poor, affects the safety of lifting process.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of gauntry crane traveling gear.
The utility model is achieved through the following technical solutions:
A kind of gauntry crane traveling gear, comprise fixed guide, hold-down arm, the T-shaped structure of described fixed guide, described hold-down arm lower end is connected with moving guide rail by mounting flange, the U-shaped structure of described moving guide rail, described mounting flange be circumferentially provided with some groups of coupling assemblings, first group of track adjusting wheel is provided with between vertical section one side of described fixed guide and moving guide rail, second group of track adjusting wheel is provided with between the vertical section another side of described fixed guide and moving guide rail, one group of BOGEY WHEEL is provided with between the vertical section upper side of described fixed guide and moving guide rail.
As optimal technical scheme of the present utility model, described coupling assembling comprises tie bolt, lock washer and jam nut.
As optimal technical scheme of the present utility model, described first group of track adjusting wheel, second group of track adjusting wheel are arranged symmetrically with about between fixed guide.
As optimal technical scheme of the present utility model, described BOGEY WHEEL touches with the chute bottom connection of fixed guide bottom.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging fixed guide, moving guide rail, first group of track adjusting wheel, second group of track adjusting wheel and BOGEY WHEEL, like this when hoisting crane adjustment position, can guarantee that under the effect of first group of track adjusting wheel, second group of track adjusting wheel and BOGEY WHEEL hoisting crane keeps stability adjusting in the process of position, guarantee the safety in lifting process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. fixed guide; 2. moving guide rail; 3. the first track adjusting wheel; 4. the second track adjusting wheel; 5. BOGEY WHEEL; 6. mounting flange; 7. hold-down arm; 8. coupling assembling.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of gauntry crane traveling gear, comprise fixed guide 1, hold-down arm 7, the T-shaped structure of described fixed guide 1, described hold-down arm 7 lower end is connected with moving guide rail 2 by mounting flange 6, the U-shaped structure of described moving guide rail 2, described mounting flange 6 be circumferentially provided with some groups of coupling assemblings 8, wherein said coupling assembling 8 comprises tie bolt, lock washer and jam nut.First group of track adjusting wheel 3 is provided with between vertical section one side of described fixed guide 1 and moving guide rail 2, second group of track adjusting wheel 4 is provided with between the vertical section another side of described fixed guide 1 and moving guide rail 2, wherein said first group of track adjusting wheel 3, second group of track adjusting wheel 4 is arranged symmetrically with about between fixed guide 1, can guarantee stability in moving guide rail 2 moving process like this.
Be provided with one group of BOGEY WHEEL 5 between the vertical section upper side of described fixed guide 1 and moving guide rail 2, wherein said BOGEY WHEEL 5 touches with the chute bottom connection of fixed guide 1 bottom, can play load-bearing effect like this.Like this when hoisting crane adjustment position, can guarantee that under first group of track adjusting wheel, 3, second group of track adjusting wheel 4 effect with BOGEY WHEEL 5 hoisting crane keeps stability adjusting in the process of position, guarantee the safety in lifting process.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
