Abstract

The utility model discloses a detachable heavy portal frame which comprises an inverted V-shaped bracket, a bearing truss and a lifting lug, wherein the top end of the bracket is welded and connected to a lower connecting plate, a fixing frame used for fixing the bracket is arranged outside the top end of the bracket, an upper connecting plate is welded at the upper end of the bearing truss, the upper connecting plate is connected with the lower connecting plate through a nut, the lifting lug extends down from the lower connecting plate, a lifting hole is formed in the lifting lug, and the lifting hole is in sliding fit with a chain block assembly arranged in the lifting hole in a penetrating manner. The detachable heavy portal frame has the advantages of greatly increasing the installation efficiency and precision and reducing the labor expand and is simple in structure and convenient to operate.

Description

A kind of detachable heavy portal frame
Technical field
The utility model relates to a kind of support, especially a kind of open work for dynamo-electric installation project, can realize the detachable heavy gantry support of the in place and enhanced feature of larger heavy wares.
Background technology
Larger heavy wares in place and be lifted at the position that occupies outbalance in dynamo-electric the installation, because larger heavy wares monomer weight is larger, and the camp site condition is often immature, it is almost impossible that larger heavy wares relies on manpower fully, and easily cause personal injury, to construction, bring potential safety hazard.Therefore in the urgent need in a kind of open work that can be used in dynamo-electric installation project, can realize the detachable heavy support of the in place and enhanced feature of larger heavy wares.
The utility model content
The purpose of this utility model is to provide and a kind ofly can greatly improves installation effectiveness and precision, reduces simultaneously the detachable heavy gantry support of manpower expenditure.
The utility model adopts following technical scheme:
A kind of detachable heavy portal frame comprises: be the support of inversion " V " shape, top and the lower connecting plate of described support are welded to connect, and the arranged outside of cantilever tip is useful on support bracket fastened adapter plate; Load truss, described load truss lower end is welded with upper junction plate, by nut, is connected between upper junction plate and lower connecting plate; And the hanger from lower connecting plate to downward-extension, on hanger, be provided with lifting hole(eyelet), lifting hole(eyelet) with place jack assembly bearing fit wherein.
Preferably, portal frame is symmetrical structure.
Preferably, the jack assembly comprises pulley and the jack be used to promoting heavy wares.
Preferably, jack is wrapped on pulley.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
Owing to according to portal frame of the present utility model two ends, adding for jack fixing and the lifting heavy device, thereby the principle of using wheel shaft has played the effect of Labor-saving high-efficiency, realized the lifting of heavy single devices and in place, installation effectiveness and precision have greatly been improved, reduce simultaneously the manpower expenditure, and simple in structure, easy to operate.
The accompanying drawing explanation
Fig. 1 is block diagram of the present utility model;
Fig. 2 is that equipment passes through the schematic diagram that the utility model promotes;
Fig. 3 is that equipment passes through the utility model and schematic diagram in place.
Wherein: 1, load truss, 2, upper junction plate, 3, lower connecting plate, 4, hanger, 5, adapter plate, 6, support, 7, jack.
The specific embodiment
Below according to embodiment, the utility model is described in further detail.
Figure 1 illustrates the constructional drawing of detachable heavy portal frame, comprising: be the support 6 of inversion " V " shape, the top of described support and lower connecting plate 3 are welded to connect, and the arranged outside of cantilever tip is useful on support bracket fastened adapter plate 5; Load truss 1, described load truss lower end is welded with upper junction plate 2, by nut, is connected between described upper junction plate and described lower connecting plate; And the hanger from lower connecting plate 3 to downward-extension 4, on described hanger, be provided with lifting hole(eyelet), lifting hole(eyelet) with place jack 7 bearing fits wherein.
Figure 2 illustrates the concrete application of detachable heavy portal frame in equipment lifting, lifting means provides platform for the horizontal transport of equipment, and the utility model use capable of being combined realizes the lifting of equipment.
Figure 3 illustrates the concrete application of detachable heavy portal frame in equipment is in place, this mode has improved the precision of installing, and has reduced the manpower expenditure, has improved installation effectiveness.
In the novel concrete practice of this use, the mode of removably connecting between load truss 1 and support 6 greatly facilitates on-the-spot operation, avoided moving deficiency of the present utility model because narrow space can not utilize crane, can be applicable to flexibly larger single devices installation and in place in.The lifting that jack 7 has been realized heavy wares is installed at hanger 4 places, has avoided the weak point of manpower.Arranging of adapter plate 5 improved bearing capacity of the present utility model.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
