Technical Field

The utility model relates to a case roof beam steel formwork single armed hoist.

Background

T roof beam/case roof beam steel form is a template that is used for the overhead crane, bridge construction in-process, be equipped with the stock frame on the steel form, the steel column that the stock frame erect is the stand, the steel column that is violently on is the spreader, current steel form needs the lifting gear to hoist the template to the station or lift from the station when overhead crane, bridge use, for the ease of lifting by crane, generally all fix solid fixed ring (hoist) of people's welding on the current steel form, it lifts by crane the removal to hook or bind solid fixed ring through the lifting gear, because current fixed ring position is fixed, can' T adjust and lift by crane centrobaric position admittedly, be not suitable for in the actual operation, and gu fixed ring appears the potential safety hazard for hoist stress point is little easily.

SUMMERY OF THE UTILITY MODEL

In view of the defect that current case roof beam steel form lifted by crane exists, the utility model aims to solve the technical problem be: the utility model provides a case roof beam steel form single armed hoist that is used for adjustment of case roof beam steel form centrobaric.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: the utility model provides a box girder steel formwork single armed hoist, includes:

the single-arm casing column is hollow, stand column fixing holes are symmetrically formed in two sides of the single-arm casing column, and the single-arm casing column penetrates through the stand column fixing holes and the steel template stand column through bolts or steel pins to enable the single-arm casing column to be fixed with the stand column;

the horizontal suspension arm is horizontally arranged on one side of the single-arm sleeve column, a row of fixing through holes are formed in the horizontal suspension arm, and the two sides of the lower end of the horizontal suspension arm are provided with widening ribs extending outwards.

This box girder steel form single armed hoist is used to install the single armed hoist additional in the activity on the stand of steel form, during the jack-up, just can come the fixed through hole of rotatory suspension as required to adjust the steel form focus.

Furthermore, a handle is further arranged on the single-arm sleeve column. The stand fixed orifices on the single-arm hoist of being convenient for of above-mentioned design are relative with the current cross-under hole on the stand.

Compared with the prior art, the utility model has the advantages of: not only can adjust the center of gravity of the steel template to be stable, but also is very convenient to use.
