Description
Technical field
The utility model belongs to crane field, is specifically related to a kind of guardrail, particularly a kind of crane in bridge type electric turnover guardrail.
Background technology
Be arranged on the guardrail outside crane girder upper end, in maintenance, the fender guard of necessity during maintenance hoisting crane, guardrail is fixed on the upside of crane girder, its height should meet the fixed value that national safety standard specifies, in most of hoisting crane, namely the vertex of guardrail is the vertex of hoisting crane, the height of conventional hoist guardrail is fixed value, when using the factory building of hoisting crane not at same absolute altitude, during design, the vertex of guardrail should lower than the minimum absolute altitude on roof, be unfavorable for like this maximally utilising factory building, cause many unnecessary wastes, and existing overturn guardrail all needs manually to complete, increase the labour intensity of workman, add maintenance, the burden safeguarded, the workman that some awareness of safety are poor, increasing of guardrail is not carried out when maintenance work, the serious generation even causing safety misadventure, therefore, provide a kind of easy to use, simple to operate, time saving and energy saving, crane in bridge type electric turnover guardrail is securely very important.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of easy to use, simple to operate, time saving and energy saving, crane in bridge type electric turnover guardrail securely.
The purpose of this utility model is achieved in that a kind of crane in bridge type electric turnover guardrail, it comprises girder, described girder side surface upper part is provided with bearing seat and electric expansion bar, described bearing seat is by the two ends of bearings axle, described electric expansion bar is horizontal through axle, guardrail is connected with on the upside of described axle, big gear wheel is provided with in the middle part of described axle, the miniature gears engaged with big gear wheel is provided with on the downside of described big gear wheel, described miniature gears is connected with actuating device, and described actuating device is fixed on girder side.
The quantity of described bearing seat and electric expansion bar is 2.
Described electric expansion bar is perpendicular to girder side.
Described axle is provided with the horizontal through hole matched with electric expansion bar.
Described actuating device comprises drive motor and retarder.
The beneficial effects of the utility model: the connecting portion of guardrail and girder is arranged on girder side surface upper part by the utility model, actuating device realizes 180 degree of rotations of axle and guardrail by gear transmission, adopt the horizontal through hole in electric expansion bar fitted shaft to carry out on guardrail the next spacing simultaneously, the guardrail rolling up state can play actv. protective effect, the guardrail turned down under state does not affect the operation of hoisting crane, can better utilize factory building yet; The utility model has easy to use, simple to operate, time saving and energy saving, advantage securely.
