Abstract
The utility model relates to an integral crown block shield which comprises an upper shield plate, a side plate, ward off rope rods, a center guard board and connecting bolts, wherein the upper shield plate adopts the radian of an original crown block shield, and is integrally welded with the ward off rope rods through the annular side plate of which the radian is the same as that of the upper shield plate and the semicircular center guard board; each ward off rope rod is made of a seamless steel tube. Compared with the prior art, the integral crown block shield has the benefits that through the adoption of the integral structure, the strength is enhanced, the structure is simple, and the maintenance and replacement are easy.
Description
Technical field
The utility model relates to a kind of weight-lifting equipment accessory, relates in particular to a kind of integral type overhead traveling crane guard shield.
Background technology
In the construction operation of oil field, the overhead traveling crane guard shield of various service machines and rig is to be all fixed on two support plates of overhead traveling crane side plate together with gear rope bar by bolt, when overhead traveling crane work, steel rope is scratching gear rope bar very easily, cause gear rope bar and tie bolt distortion, the connecting bore enlargement deformation on overhead traveling crane guard shield not only when serious, two support plates on overhead traveling crane side plate also can be at torsional deflection under forceful action, when two support plate assemblings, there is certain angle requirement, make troubles therefore to maintenance, replacing.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, and a kind of integral type overhead traveling crane guard shield that guard shield and gear rope bar are carried out to integrated design is provided.
In order to address the above problem, the utility model by the following technical solutions:
Integral type overhead traveling crane guard shield, comprise guard shield upper plate, side plate, gear rope bar, center backplate, tie bolt, described guard shield upper plate adopts the radian of former overhead traveling crane guard shield, side plate and semi-round center backplate by an identical radian measure annular are welded as a whole with gear rope bar, and gear rope bar is that solid drawn pipe is made.
Compared with prior art, the beneficial effects of the utility model are:
Adopt one-piece construction, strength increase, simple in structure, for ease of maintenaince change.
