Abstract
The invention relates to a rotary electric crane. The rotary electric crane comprises an upright post and a crane jib, wherein one end of the crane jib is fixedly connected to the fixed upright post; the upright post comprises a fixed post and a rotary post which are in butt joint; a first positioning ring and a second positioning ring which are horizontal and are provided with central holes are fixedly arranged in the rotary crane jib; a rotation shaft is fixedly arranged in the first positioning ring and the second positioning ring respectively; a bearing pedestal is fixedly arranged in the fixed post; a first bearing is arranged on the bearing pedestal; a second bearing is arranged above the first bearing; a pressing board is arranged between the first bearing and the second bearing; the upper end of the second bearing is tightly pressed against the lower side of the second positioning ring; and the first bearing and second bearing are matched with the rotation shaft respectively to rotatablely arrange the rotary post above the fixed post. Because radial force and axial force are shared by the bearings when the rotary electric crane works, the stability of the rotary electric crane can be ensured even if the rotary post is longer; at the same time, the electric crane with the structure is freely and reliably rotated and high in security.
Description
Technical field
The present invention relates to a kind of rotary electric hangs.

Summary of the invention
The purpose of this invention is to provide a kind of stability, safe rotary electric hangs.
For achieving the above object, the technical solution used in the present invention is:
A kind of rotary electric hangs, comprise that column, an end are fixedly connected on the arm on the described vertical columns, described column comprises fixed leg, the column spinner that connects, described arm is fixedly connected on the described pivot arm, the internal fixation of described pivot arm is provided with first nest with centre hole, second nest of level, is set with S. A. in described first nest, second nest;
Described fixed leg internal fixation is provided with bearing seat, described bearing seat is arranged on the interface that described fixed leg and described column spinner connect, on the described bearing seat clutch shaft bearing is installed, the top of described clutch shaft bearing is provided with second bearing, be provided with pressing plate between described clutch shaft bearing and described second bearing, the upper end of described second bearing pushes against below described second nest, described clutch shaft bearing, described second bearing matches with described S. A. the rotatable top that is installed in described fixed leg of described column spinner respectively.
Preferably, described S. A. is a stepped shaft.
Preferably, described bearing seat is arranged on the interface that described fixed leg and described column spinner connect.
Preferably, be provided with adapter plate in the described fixed leg with centre hole, described adapter plate is positioned at the below of described bearing seat, on the described adapter plate third axle being installed holds, the bottom of described S. A. is installed in described third axle and holds, the part of described S. A. reaches the below of described adapter plate, and the lower end of described S. A. is provided with baffle plate, and the below of described baffle plate is provided with nut described baffle plate is pressed on the below that described third axle holds.
Preferably, described pressing plate is an annular pressing plate.
Preferably, the outer wall of described column spinner is provided with the rotation push rod.
Preferably, described rotation push rod and described column spinner are hinged, and described column spinner is provided with claw, and when described rotation push rod is threaded to when paralleling with described column spinner, described rotation push rod is fixed in the described claw.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
Since of the present invention electronic when hanging work suffered diametral load and axial force share by the clutch shaft bearing and second bearing, therefore, even when column spinner is longer, this electronic stability of hanging still can be guaranteed, simultaneously, the electronic rotation flexibility and reliability of hanging of this structure, safe.

The specific embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described:
Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 3.
A kind of rotary electric hangs, and comprises that column, an end are fixedly connected on the arm on the vertical columns, and column comprises fixed leg, the column spinner that connects, and arm is fixedly connected on the pivot arm;
The internal fixation of pivot arm is provided with first nest with centre hole, second nest of level, is set with S. A. in first nest, second nest, and S. A. is a stepped shaft, and the lower end of S. A. reaches the outside of the lower end of column spinner;
The fixed leg internal fixation is provided with bearing seat, bearing seat is arranged on the interface that fixed leg and column spinner connect, clutch shaft bearing is installed on the bearing seat, the top of clutch shaft bearing is provided with second bearing, be provided with annular pressing plate between the clutch shaft bearing and second bearing, the upper end of second bearing pushes against below second nest, and clutch shaft bearing, second bearing match with S. A. respectively the rotatable top that is installed in fixed leg of column spinner;
Be provided with adapter plate in the fixed leg with centre hole, adapter plate is positioned at the below of bearing seat, third axle is installed on the adapter plate to be held, the bottom of S. A. is installed in third axle and holds, the part of S. A. reaches the below of adapter plate, the lower end of S. A. is provided with baffle plate, and the below of baffle plate is provided with nut baffle plate is pressed on the below that third axle holds;
The outer wall of column spinner is provided with the rotation push rod that is hinged with column spinner, and column spinner is provided with claw.
When rotary electric hangs, will rotate push rod and screw off and promote to rotate push rod, column spinner driven rotary axle rotates, and stops to promote the rotation push rod when arm is threaded to desired location; When not needing rotary electric to hang, rotation rotation push rod will rotate push rod then and be fixed in the claw to paralleling with column spinner.The electronic diametral load and the axial force that are subjected to of hanging shared by the clutch shaft bearing and second bearing, so this electric lifting tool has higher safety, stable, flexibly, reliable.
