Abstract
The utility model provides a hydraulic loading and unloading machine and solves problems that a present loading and unloading machine cannot load and unload a preset beam with various spans and has a large size. The hydraulic loading and unloading machine comprises a gantry type frame formed by an upper cross beam and stand columns, an elevating beam and a walking mechanism, wherein an elevating hydraulic cylinder driving the elevating beam to move up and down is arranged in each stand column; a piston rod of each elevating hydraulic cylinder is connected with the elevating beam; a ground beam is fixedly connected to the lower end of each stand column; and the walking mechanism is connected with the ground beam. The hydraulic loading and unloading machine ensures loading and unloading work of the preset beam (except a passage-use beam) with various spans; the hydraulic loading and unloading machine can work with only one beam being spanned, so the hydraulic loading and unloading machine, with a small structure, occupies little space.
Description
Technical field
The utility model relates to loading-unload machine technical field, particularly a kind of for promoting the hydraulic loading-unloading machine of precast beam.
Background technology
Abroad, loader-unloader operating technique origin early, development has the loading-unload machine that is specifically designed to bridge handling as professional loading-unload machine Norway NRS company of maker and Italian Nicola company etc., be absorbed in loading-unload machine field decades, to domestic loader-unloader manufacture and design and erecting beam construction technogenic influence larger, there is good brand image and public praise, in Larger Engineering Projects in the world, there is good share of market.They have than more complete product line, but expensive price is the biggest obstacle that it continues to expand share of market.
Through China engineering staff unremitting effort of decades, the precast beam span that domestic loader-unloader not only lifts by crane constantly increases, and lift heavy and version also updated, domestic loader-unloader poor stability, quality is unreliable, build is huge shortcoming have been overcome.Loader-unloader market forms gradually, and the loading-unload machine maker of specialty arises at the historic moment.But existing loader-unloader volume is larger, take up room also larger, can not meet the handling of various beams simultaneously, and the inconvenience getting into smooth also very.
Utility model content
The utility model provides a kind of hydraulic loading-unloading machine, solves the precast beam that existing loader-unloader can not load and unload various spans, and the larger problem of volume.
The technical solution of the utility model is achieved in that a kind of hydraulic loading-unloading machine, comprise the gantry type frame, lifting beam and the traveling gear that by entablatrance and column, are formed, in column, be provided with the lifting hydraulic cylinder that drives lifting beam up-and-down movement, the piston rod of lifting hydraulic cylinder is connected with lifting beam, column lower end is fixedly connected with grade beam, and described traveling gear is connected with grade beam.
Wherein, preferably, on described column, be provided with round.
Wherein, preferably, in described lifting beam, be provided with the orienting lug being stuck on column inwall.
Wherein, preferably, described traveling gear comprises inverted L shape support and road wheel, and road wheel is fixed on the support of falling L below.
Wherein, preferably, described inverted L shape support is connected by bearing pin with described grade beam.
The beneficial effects of the utility model:
The utility model has partly carried out brand-new design by existing loader-unloader structure and mechanism, guarantees that complete machine adapts to the handling of various span precast beams (except the special beam of visitor); This loader-unloader only promotes operation across a slice beam, thereby self structure is little, does not take larger space, for small spaces such as having various circuits or pipeline on Liang Chang, all can adapt to; This loader-unloader can be by the dilatory movement of beam transportation vehicle, also can be attached on the beam sheet of transhipment and shift together thereupon; Can on each beam sheet, transport easily, also can between each beam making field, transport easily; This body structure is little, mechanism simple, and cost taken by themselves is low; Utilize this equipment bale handle, can replace conventional bale handle door machine, equipment is saved very large expense; The facility of considering bale handle, the layout of precast beam field can be arranged on the roadbed of end of the bridge, needn't build specially precast beam field, can save expropriation of land scope, reduces engineering cost.Can be on general husky horsestone road surface, the pan soil road surface of simply rolling lifting beam sheet, grounding pressure≤0.7MPa, transhipment grounding pressure≤0.7MPa, does not need hard surface, can adapt to general beam making field ground, has reduced beam fabricating yard construction expense, strong adaptability.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the hydraulic loading-unloading machine of the utility model embodiment;
Fig. 2 is that Fig. 1 is along A to view.
In figure, 1. entablatrance, 2. column, 3. lifting beam, 4. lifting hydraulic cylinder, 5. grade beam, 6. round, 7. orienting lug, 8. inverted L shape support, 9. road wheel, 10. bearing pin.
The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the present embodiment provides a kind of hydraulic loading-unloading machine, comprise the gantry type frame, lifting beam 3 and the traveling gear that by entablatrance 1 and column 2, are formed, in column 2, be provided with the lifting hydraulic cylinder 4 that drives lifting beam 3 up-and-down movements, the piston rod of lifting hydraulic cylinder 4 is connected with lifting beam 3, column 2 lower ends are fixedly connected with grade beam 5, and described traveling gear is connected with grade beam 5.Entablatrance 1 is made by channel beam, mainly plays the effect that connects two heel posts.Lifting beam 3 adopts welding box-shaped structure, can carry and hang 50m and following various highway Prefabricated Concrete beam.
Wherein, on column 2, be provided with round 6, by means of pin, can hydraulic climbing type lifting heavy.
Wherein, be provided with the orienting lug 7 being stuck on column inwall in lifting beam 3, the effect of orienting lug 7 is that the two ends of lifting beam are just stuck in column.
Wherein, traveling gear comprises inverted L shape support 8 and road wheel 9, and road wheel 9 is fixed on the support of falling L 8 belows, and inverted L shape support 8 is connected by bearing pin 10 with grade beam 5.Bearing pin connects and can install and remove flexibly, makes the complete machine can be flexibly for various working conditions.
When bale handle, grade beam carries out secure support, forbids a roller tire to support and carries out operation; During bale handle, grade beam two ends diff-H can not surpass 20mm; When depending on concrete girder transferring, loader-unloader must make concrete beam carry out secure support.Hydraulic efficiency pressure system is mainly comprised of pumping plant, oil circuit, oil cylinder.Hydraulic efficiency pressure system is the lifting power system of whole loader-unloader, during lifting, opens pumping plant, promotes oil cylinder, drives and promotes the rising of girder bale handle.System is provided with the fender guard of hydraulic pressure, prevents overload, slips the generation of the situations such as hook.
