Abstract
The utility model discloses a hoist girder construction of stretching out and drawing back, include the stand of both sides and connect the crossbeam on two stands, install the girder on the crossbeam, the lower extreme of girder is equipped with the guide rail, is equipped with along the electric block group that the guide rail removed its characterized in that on the guide rail: one side that the lower extreme of girder is located the guide rail still is equipped with a flexible roof beam along girder axial displacement, the lower extreme of flexible roof beam is equipped with the guide rail equally, is equipped with on its guide rail along the electric block group that the guide rail removed. The utility model discloses a hoist girder construction of stretching out and drawing back guarantees two trans -regional butt joints, has avoided the product after the process is accomplished to the right side station, still carries the left side station with the help of other transport mode with the product, has solved product transport and lifting means, and the artifical quantity that significantly reduces improves production efficiency, has reduced operating personnel's accident rate.
Description
Technical field
The utility model relates to hoisting crane technical field, particularly a kind of crane telescopic girder construction.
Background technology
Crane in bridge type be crossbearer in workshop, warehouse and overhead, stock ground carry out the weight-lifting equipment of material handling.Two ends due to it are seated on tall and big concrete column or metallic support, and shape is like bridge.The crane span structure of crane in bridge type along be laid on both sides overhead on track longitudinally run, the space handling material below crane span structure can be made full use of, not by the obstruction of wayside equipment.It is a kind of elevator machinery that range of use is the widest, quantity is maximum, existing crane in bridge type is when trans-regional operation, generally complete corresponding operation on the station of side after, other mode of transport is adopted product to be transported to the station of opposite side, the mode of transport of usual employing is a dead lift, labor intensity of operating staff is large, and there is potential safety hazard, easily causes personnel's accident.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides one and can solve the problem, the crane telescopic girder construction of enhancing productivity.
The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of crane telescopic girder construction, comprise the column of both sides and connect the crossbeam of two column upper ends, described crossbeam is provided with girder, the lower end of described girder is provided with guide rail, guide rail is provided with the electric block group along guide rail movement, it is characterized in that: the side that the lower end of described girder is positioned at guide rail is also provided with a telescopic girder moved axially along girder, the lower end of described telescopic girder is provided with guide rail equally, and its guide rail is provided with the electric block group along guide rail movement.
As further improvement of the utility model, described electric block group is made up of electric drive dolly and some cable trolleys, and cable connects electric drive dolly after being carried by cable trolley.
As further improvement of the utility model, the side of described telescopic girder is provided with the safety stopping device for limiting telescopic girder shift position.
As further improvement of the utility model, one end of described telescopic girder is also provided with second protection bolt.
The beneficial effects of the utility model are: crane telescopic girder construction of the present utility model, ensure two trans-regional docking, avoid product after right side station completes operation, still by other mode of transport, product is transported to left side station, solve product carrying and lifting means, greatly reduce artificial quantity, enhance productivity, reduce the accident rate of operating personal.
