Abstract
The utility model provides a kind of fixed column type polar bridge crane, including annular walking track, girder, lifting mechanism, end carriage and center stand column, lifting mechanism is mounted on girder, girder one end is connect with end carriage, the other end is rotatablely connected by rotating mechanism and center stand column, the center line of annular walking track is conllinear with the pivot center of rotating mechanism, end carriage includes the walking round frame for being located at both ends, traveling wheel along annular walking track travel is installed in walking round frame, walking round frame keeps the pivot center of traveling wheel conllinear with the pivot center of rotating mechanism towards girder bending.Girder one end is by driving mechanism drives edge annular walking track travel, the girder other end is rotatablely connected by rotating mechanism and center stand column, then the lifting mechanism on girder can rotate in the venue handling with girder, since the both ends of girder pass through annular walking track and center stand column support respectively, handling process is steady and operation is convenient.
Description
Technical field
The utility model relates to crane fields, and in particular to a kind of fixed column type polar bridge crane.
Background technique
In workshop or workshop, workpiece handling, but overhead traveling crane are carried out by bridge crane or cantilever crane mostly
Machine can only walk on the track extended parallel at two, and girder can only be moved back and forth along the extending direction of track, it is difficult to meet certain
Girder is needed to rotate to carry the requirement of article in a little special operation conditions, and the cantilever of cantilever crane is longer, fluctuation of service, system
Make higher operating costs.
Utility model content
The technical problem to be solved by the utility model is to provide the bridge cranes that one kind can carry out fixed column type rotation.
To achieve the above object, the technical solution that the utility model is taken are as follows: a kind of fixed column type polar bridge crane, packet
It includes annular walking track, girder, lifting mechanism, end carriage and center stand column, lifting mechanism to be mounted on girder, girder one end and end
Beam connection, the other end are rotatablely connected by rotating mechanism and center stand column, the center line of annular walking track and rotating mechanism
Pivot center is conllinear, and end carriage includes the walking round frame for being located at both ends, is equipped in walking round frame along annular walking track travel
Traveling wheel, walking round frame keep the pivot center of traveling wheel conllinear with the pivot center of rotating mechanism towards girder bending.
Rotating mechanism includes the top rotary table and lower rotary table of rotation connection, and top rotary table is fixedly connected with end of main beam, lower rotary table
It is fixedly connected with center stand column.
Lifting mechanism includes the lifting trolley that can be moved back and forth along girder, and lifting trolley is equipped with hoisting drum, raising volume
Cylinder is connected with raising suspender, and raising suspender is grab bucket, electromagnet or suspension hook.
The pivot center of rotating mechanism and the centerline collineation of center stand column.
The fixed column type polar bridge crane of the utility model, including annular walking track, girder, lifting mechanism, end carriage
And center stand column, lifting mechanism are mounted on girder, girder one end is connect with end carriage, and the other end is vertical by rotating mechanism and center
The center line of column rotation connection, annular walking track is conllinear with the pivot center of rotating mechanism, and end carriage includes the row for being located at both ends
Wheel carrier is walked, the traveling wheel along annular walking track travel is installed in walking round frame, walking round frame makes to walk towards girder bending
The pivot center of wheel and the pivot center of rotating mechanism are conllinear.Girder one end is by driving mechanism drives edge annular walking track row
It walks, the girder other end is rotatablely connected by rotating mechanism and center stand column, then the lifting mechanism on girder can be with girder in place
Interior rotation handling, since the both ends of girder pass through annular walking track and center stand column support respectively, handling process is steady and grasps
It is convenient to make.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the utility model one；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The fixed column type polar bridge crane of the utility model, as shown in Figures 1 and 2, including annular walking track 1,
Girder 2, lifting mechanism 3, end carriage 4 and center stand column 5.
Lifting mechanism 3 is mounted on girder 2, and including the lifting trolley that can be moved back and forth along girder, lifting trolley is equipped with
Hoisting drum, hoisting drum are connected with raising suspender, and raising suspender is grab bucket, electromagnet or suspension hook.
2 one end of girder is connect with end carriage 4, and the other end is rotatablely connected by rotating mechanism 6 and center stand column 5, rotating mechanism 6
Top rotary table and lower rotary table including rotation connection, top rotary table are fixedly connected with 2 end of girder, and lower rotary table and center stand column 5 are fixed
Connection.
End carriage 4 includes the walking round frame for being located at both ends, and the walking walked along annular walking track 1 is equipped in walking round frame
Wheel, walking round frame keeps the pivot center of traveling wheel conllinear with the pivot center of rotating mechanism 6 towards the bending of girder 2, in addition, annular
The center line of walking track 1 is conllinear with the pivot center of rotating mechanism 6, to guarantee traveling wheel along the annular walking steady row of track 1
It walks without derailing.
The centerline collineation of the pivot center of rotating mechanism 6 and center stand column 5, the then structure at crane center stand column position
Regular to be easily installed arrangement, certainly, in other embodiments, the pivot center of rotating mechanism 6 can be inclined according to actual place demand
Center line from center stand column 5.
In use, 2 one end of girder is walked by driving mechanism drives edge annular walking track 1,2 other end of girder passes through rotation
Mechanism 6 and center stand column 5 are rotatablely connected, then the lifting mechanism 3 on girder 2 can rotate in the venue handling with girder 2, due to master
The both ends of beam 2 pass through annular walking track 1 respectively and center stand column 5 supports, and handling process is steady and operation is convenient.
Finally, it is stated that: above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this
The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.
