Abstract
The utility model relates to a bridge deck crane prevents mechanism that topples. The purpose is that preventing of providing topples the mechanism and should be able to adapt to plank road construction requirements for bridge deck crane can steadily walk on the track, has security height, convenient to use's technical characterstic in addition. Technical scheme is: a bridge deck crane prevents mechanism that topples which characterized in that: including arranging a plurality of protection wheelset in bridge deck crane's travelling car both sides respectively, each protection wheelset is including installing at least one level protection wheel and at least one the vertical protection wheel on the wheel carrier to the shaft of level protection wheel and the shaft mutually perpendicular of vertical protection wheel.
Description
Technical field
The utility model relates to erection crane technical field, specifically a kind of overturn-preventing mechanism of erection crane.
Background technology
Forest pavement integrates the road of going sightseeing with body-building function, and most of section navigates among forest or greenery patches, is convenient for people to closely get close to natural ecological environment.Current forest pavement be generally carry out widening on the basis of existing road before, repair, heavily paving form, less to environmental destruction, but for approach system imperfection or mountain area newly developed, build forest pavement to need to cut down a large amount of trees on the way, and to cause ground vegetation in work progress and destroy largely, impact to local environment.
For the problems referred to above, the mode that applicant proposes to set up plank road carrys out alternative common forest pavement, in the work progress of plank road, adopt track laying on plank road, erection crane is walked along track while build forward the mode of plank road, because erection crane is walked on the plank road built well, therefore can reduce floor space, reduce the impact on ecological environment.But because erection crane is walked in orbit, need the derailing avoiding it may cause because of crank, the overturn-preventing mechanism of this erection crane of configuration of therefore still needing.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, a kind of overturn-preventing mechanism of erection crane is provided, this overturn-preventing mechanism should be able to adapt to plank road construction requirement, makes erection crane can stabilized walking in orbit, and has safety technical characterstic high, easy to use.
The utility model have employed following technical scheme:
A kind of overturn-preventing mechanism of erection crane; it is characterized in that: several protection wheels comprising the travelling car both sides being arranged in erection crane; each protection wheels comprise be arranged on wheel carrier at least one level protection wheel and at least one vertically protect wheel, and level protection wheel wheel shaft and vertically protect the wheel shaft of taking turns mutually vertical.
As preferably, in described protection wheels, level protection wheel and vertically protection wheel are steel wheel, and the steel wheel outer of level protection wheel is enclosed with polyurethane circle.
The beneficial effects of the utility model are: in the utility model; protection wheels are arranged on the both sides of travelling car; when erection crane rocks; vertical protection wheel is resisted against the bottom surface of the top wing plate of I-shaped track; level protection wheel is resisted against the outside of the web of I-shaped track; thus preventing erection crane derailing from toppling, safety is high, easy to operate.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As Fig. 1, Fig. 2, shown in Fig. 3, the overturn-preventing mechanism of the erection crane that the utility model provides, be mainly used in preventing erection crane 8 from departing from I-shaped track 7 and toppling, comprise several protection wheels (travelling car each side have 2 to protect wheels) being arranged in travelling car both sides, each protection wheels comprises and passes through bearing, 1-1 (whole wheel is roughly positioned at horizontal plane) and at least one vertically protection wheel 1-2 (whole wheel is roughly positioned at vertical plane) are taken turns in wheel shaft at least one level protection be arranged on wheel carrier 2, and level is protected the wheel shaft of wheel and is vertically protected the wheel shaft of taking turns mutually vertical.Usually, each protection wheels comprise two levels protection wheel and one vertically protect wheel, vertically protection wheel is between two levels protection wheels.Vertical protection wheel is arranged on the outside of I-shaped track, and below the top wing plate 7-1 being positioned at I-shaped track, level protection wheel is positioned at outside the web 7-2 in I-rail road.When erection crane rocks, vertical protection wheel is resisted against the bottom surface of the top wing plate of I-shaped track, and level protection wheel is resisted against the outside of the web of I-shaped track, thus prevents erection crane derailing from toppling.In described protection wheels, level protection wheel and vertically protection wheel are steel wheel, and the steel wheel outer of level protection wheel is enclosed with polyurethane circle, and vertically polyurethane circle also can be wrapped up as required in the steel wheel outer of protection wheel.
As shown in figs 2-4, above-mentioned overturn-preventing mechanism can form the walking mechanism of erection crane together with the road wheel assembly of erection crane.Described road wheel assembly is mainly used in the walking on I-shaped track 7, comprise some to road wheel 3 (being a pair front-wheel and pair of rear wheels in Fig. 1), two wheels of every a pair road wheel are walked respectively on the top wing plate 7-1 of two I-shaped tracks, connected by axletree 4 between two wheels, axletree is arranged on the bottom of the travelling car 5 of erection crane by bearing, wherein have at least a pair road wheel to be driven by reducer by motor 6.Usually, described road wheel is steel wheel 3-1 (being arranged on axletree), and the outer of steel wheel is enclosed with rubber ring 3-2, can increase the frictional force of road wheel and I-shaped rail top face.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have a lot of distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
Claims (2)
