Description
Technical field
The utility model relates to a kind of hoisting crane, a kind of specifically automatic lifting formula crane in bridge type.
Background technology
All at home mechanical processing industry and smelters all be unable to do without crane in bridge type at present, but the such problem of existing crane in bridge type (being included in the hoisting crane of usefulness) ubiquity: very little (generally all at 80mm～120mm) cause jack to be put to enter, change of wheels is very difficult to walking rail level distance in the end carriage bottom surface.When wheel need be changed, rationally fast speed held up vehicle frame.Jack can only be put under the profile shaft bearing of wheel angle monolateral stressed, the vehicle frame picking-up is added parallels below end carriage, take away jack afterwards and overhaul change of wheels again, so not only the repair time is longer, the more important thing is monolateral stressed vehicle frame distortion, the wheel gnawing rail of causing easily of vehicle frame, phenomenon such as cause that vehicle frame is torn that the most serious is.Therefore, there is the problem that hoisting crane is safeguarded, maintenance is relatively more difficult in existing crane in bridge type, and the change of wheels difficulty is bigger, and operating rate is low.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming that above prior art exists, proposes a kind ofly can guarantee change of wheels quickly and safely, the automatic lifting formula crane in bridge type of raising operating rate.
It is that technical scheme is that the utility model solves above technical matters:
Automatic lifting formula crane in bridge type, comprise big vehicle carriage and car frame, establishing at the end carriage place, two of big vehicle carriage respectively has a hydraulic jack, on two end carriage of big vehicle carriage, respectively be provided with a cart hydraulic power unit, the cart hydraulic power unit links to each other with corresponding hydraulic jack, respectively be provided with a hydraulic jack at the both sides of car frame transmission Liang Chu, be provided with a dolly hydraulic power unit on the table top of car frame, the dolly hydraulic power unit links to each other with two hydraulic jacks of car frame.
All be provided with on the end carriage of big vehicle carriage and the end carriage of car frame and strengthen the shin plate, two girder orbit centre places of big vehicle carriage are provided with hydraulic jack the basis are installed, the end carriage bottom web of big vehicle carriage has the auxiliary hole of hydraulic jack work, the outer cant board of the end carriage of big vehicle carriage is provided with reinforced plate, and has the technology square hole of hydraulic jack installation and maintenance.
Be welded with in the middle of car frame's both sides transmission beam and strengthen the shin plate, on the outer cant board of car frame, have hydraulic jack mounting process square hole.
The utility model has the advantages that: the utility model carries out design improvement to body frame structure for automotive on the basis of former conventional bridge hoisting crane.At cart, car frame's two end carriage hydraulic jack and pumping plant are installed respectively.As needs this car wheel is checked, when safeguarding, can be guaranteed evenly stressedly quickly and easily whole vehicle frame to be held up, carry out maintaining, can guarantee change of wheels quickly and safely, improve operating rate.The each maintenance and inspection of former crane in bridge type owing to be use jack, angle type bear box connect to ground locate monolateral stressed.Angle of vehicle frame held up tears wheel open, ordinary bridge crane, every maintenance once, vehicle frame held up needs to add cushion block, the dead work that vehicle frame is held up needs 3 hours.For the inclined to one side rail formula crane in bridge type more than the 75t, need to carry out jacking with the 100t jack, the dead work that at every turn holds up vehicle frame needs 10 hours.The pressure spot of jack has concentrated load on the cart track girder in addition, and not only the crane span structure easy deformation is also very big to the influence of cart rail safety.Use the utility model, no matter the bridge crane tonnage is much, as long as reasonable disposition mechanism as long as just vehicle frame integral body can be held up in 5 minutes, carries out the wheel maintain and replace at every turn.Original maintenance is with a jack vehicle frame to be held up, the easy like this phenomenons such as the vehicle frame distortion is torn, wheel gnawing rail that cause.It is evenly stressed that the utility model becomes 4 points, and whole vehicle frame is steadily held up, and guarantees that vehicle frame is not easy distortion.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, automatic lifting formula crane in bridge type, comprise big vehicle carriage and car frame, establishing at the end carriage place, two of big vehicle carriage respectively has a hydraulic jack 1, on two end carriage of big vehicle carriage, respectively be provided with a cart hydraulic power unit, the cart hydraulic power unit links to each other with corresponding hydraulic jack, respectively be provided with a hydraulic jack at the both sides of car frame transmission Liang Chu, be provided with a dolly hydraulic power unit 2 on the table top of car frame, the dolly hydraulic power unit links to each other with two hydraulic jacks of car frame.All be provided with on the end carriage of big vehicle carriage and the end carriage of car frame and strengthen the shin plate, two girder orbit centre places of big vehicle carriage are provided with hydraulic jack the basis are installed, the end carriage bottom web of big vehicle carriage has the auxiliary hole of hydraulic jack work, the outer cant board of the end carriage of big vehicle carriage is provided with reinforced plate, and has the technology square hole of hydraulic jack installation and maintenance.Be welded with in the middle of car frame's both sides transmission beam and strengthen the shin plate, on the outer cant board of car frame, have hydraulic jack mounting process square hole.
The utility model comes to a complete stop driving on safe and reliable track girder in use, starts pumping plant pulling reversing controller, makes whole vehicle frame rise to needed maintenance height.Close pumping plant again, at this moment hydraulic lock is carried out pressurize in the oil cylinder, guarantees that vehicle frame can not fall, just can safe and convenient ground change of wheels.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
