Description
Technical field
The utility model relates to weight-lifting equipment hoisting device, especially a kind of for the segment prefabricated inner arc vacuum sucker lifting appliance producing lifting of tunneling shield.
Background technology
In prior art, it is all larger that Prefabrication is used for tunneling shield section of jurisdiction volume and weight, and its profile is many in cambered surface tiles, section of jurisdiction finished product often needs lifting when Prefabrication, extrados vacuum cup is adopted during the extrados lifting of section of jurisdiction, but the lifting of section of jurisdiction the intrados mechanical suspender generally adopting inserting bolt hole to lift by crane and the clip machinery suspender being clipped in both sides.Use intrados machinery suspender lifting section of jurisdiction to there is shortcomings, comprise; Plug-in type machinery suspender is employing 4 lifting, need ground auxilian that lifting in four bolts hole of lifting pin insertion section of jurisdiction, clip machinery suspender are needed personnel's adjusting device, during lifting, due to exist stressed different time and uneven possibility, cause damaging section of jurisdiction when lifting by crane; Meanwhile, all need when lifting by crane two ground staff to assist and be fixed on suspender by section of jurisdiction, when keeping flat section of jurisdiction, need staff to follow and take off suspender, consumption people is consuming time.
Utility model content
The purpose of this utility model is to provide a kind of inner arc vacuum sucker lifting appliance, can sling and keep flat the intrados suspender of section of jurisdiction by safe ready when segment prefabricated production.
The purpose of this utility model will be realized by following technical measures: comprise fixed hook, supporting main beam frame, vacuum system, large sucker, small sucker, tracheae and electric control cabinet; Fixed hook is installed on supporting main beam frame top, supporting main beam frame is fixed vacuum system and electrical control cabinet, large sucker and small sucker is welded on the downside of supporting main beam frame, large sucker inner sleeve small sucker and inner top surface epirelief are also communicated with vacuum system by tracheae, and along outstanding in cambered surface and fixing seal bar downwards under large sucker and small sucker.
Especially, supporting main beam frame is that platform support and inside have cavity, upwards be fixed with protruding framed structure in the middle part of it, be provided with the fixed hook of intermediate openings in this framed structure upper end, tracheae is communicated with large sucker and small sucker by supporting main beam frame internal cavities.
Especially, the fixed upper limit position, top of fixed hook intermediate openings.
Especially, supporting main beam frame outer ledge fixing operation handle.
Especially, tracheae installs air filtering core.
Especially, large sucker outer ledge erection column plug proximity switch.
Advantage of the present utility model and effect: production time is more saved, easy to operate, 1 people is only needed to operate and labour intensity obviously reduces, the balance and stability of handling can be kept, ground staff is not needed to assist when keeping flat, than mechanical suspender safety, lift by crane and keep flat and all can not cause damage to section of jurisdiction, significantly shorten the lifting time.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: fixed hook 1, upper limit 2, supporting main beam frame 3, vacuum system 4, large sucker 5, small sucker 6, operating handle 7, air filtering core 8, tracheae 9, electric control cabinet 10, plunger tpe proximity switch 11.
Detailed description of the invention
The utility model principle is, intrados vacuum suction realizes having difficulties with conventional art, for guaranteeing that job safety is reliable, not only need the sucker working interface of the contoured design possessed for section of jurisdiction intrados, also need to increase design simultaneously and coordinate the location structure avoiding rocking in lifting, and increase unfailing performance and the applicability of vacuum suction by dual sucker structure.
The utility model comprises: fixed hook 1, supporting main beam frame 3, vacuum system 4, large sucker 5, small sucker 6, tracheae 9 and electric control cabinet 10.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, fixed hook 1 is installed on supporting main beam frame 3 top, supporting main beam frame 3 is fixed vacuum system 4 and electrical control cabinet 10, large sucker 5 and small sucker 6 is welded on the downside of supporting main beam frame 3, large sucker 5 inner sleeve small sucker 6 and inner top surface epirelief are also communicated with vacuum system 4 by tracheae 9, and large sucker 5 and small sucker 6 times edges are outstanding in cambered surface and fixing seal bar downwards.
In aforementioned, supporting main beam frame 3 has cavity for platform support and inside, upwards be fixed with protruding framed structure in the middle part of it, be provided with the fixed hook 1 of intermediate openings in this framed structure upper end, tracheae 9 is communicated with large sucker 5 and small sucker 6 by supporting main beam frame 3 internal cavities.The effect of supporting main beam frame 3 tool vacuum air collector.
In aforementioned, the fixed upper limit position, top 2 of fixed hook 1 intermediate openings, upper limit 2 ensure lift by crane time for fixing connecting shackle, reduce or avoid Suspension System to rotate, to ensure upper limit safety.
In aforementioned, supporting main beam frame 3 outer ledge fixing operation handle 7.
In aforementioned, tracheae 9 is installed air filtering core 8.Air filtering core 8 filters the working gas in tracheae 9, to maintain vacuum system and pipeline reliability.
In aforementioned, large sucker 5 outer ledge erection column plug proximity switch 11.Plunger tpe proximity switch 11 ensure large sucker 5 and small sucker 6 sucker contact with section of jurisdiction put in place after just carry out section of jurisdiction lifting.
In aforementioned, vacuum system 4 ensures the degree of vacuum maintaining safety lifting.
In aforementioned, the adsorption area of large sucker 5 is about 1.2m
2, the adsorption area of small sucker 6 is about 0.14m
2, small sucker 6 is for the wedge of section of jurisdiction of slinging and mould, and large sucker 5 is for the calibrated bolck of section of jurisdiction of slinging or adjacent block and mould.
In the utility model, large sucker 5 is for lifting calibrated bolck in section of jurisdiction and adjacent block, and small sucker 6 to bind block for lifting, and sucker radian requires consistent with radian in section of jurisdiction under adsorbed state.
During utility model works, whole suspender is hung on corresponding weight-lifting equipment by fixed hook 1 suspension hook, when starting to lift by crane, relies on its deadweight to be attached to by the intrados of swing pipe sheet.Vacuum system 4 produces negative pressure of vacuum by electric control cabinet 10, and negative pressure of vacuum is connected to large sucker 5 and small sucker 6 body by support cavity and tracheae 9 road, to be sling section of jurisdiction by negative-pressure adsorption.
In hoisting process, large sucker 5 and small sucker 6 alternation is switched by the size button on adjustment operation handle 7, be switched to large gear, large sucker 5 is started working, fast and the adjacent block of lifting standard, be switched to little gear, small sucker 6 is started working, lifting is bound block, small sucker 6 shape with bind block-shaped similar.
