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

Rotary electric crane
Technical field
The present invention relates to a kind of rotary electric crane.

The purpose of this invention is to provide a kind of stability, safe rotary electric crane.
For achieving the above object, the technical solution used in the present invention is:
A kind of rotary electric crane, comprise that column, an end are fixedly connected on the arm on described vertical columns, described column comprises fixed leg, the column spinner that connects, described arm is fixedly connected on described pivot arm, the inside of described pivot arm is fixedly installed the first nest with centre hole, second nest of level, is fixedly installed S. A. in described the first nest, the second nest;
described fixed leg inside is fixedly installed bearing seat, described bearing seat is arranged on the interface that described fixed leg and described column spinner connect, on described bearing seat, clutch shaft bearing is installed, the top of described clutch shaft bearing is provided with the second bearing, be provided with pressing plate between described clutch shaft bearing and described the second bearing, the upper end of described the second bearing is pushed against the below of described the second nest, described clutch shaft bearing, described the second bearing matches with described S. A. the rotatable top that is arranged on described fixed leg of described column spinner respectively.
Preferably, described S. A. is stepped shaft.
Preferably, described bearing seat is arranged on the interface that described fixed leg and described column spinner connect.
Preferably, be provided with the adapter plate with centre hole in described fixed leg, described adapter plate is positioned at the below of described bearing seat, the 3rd bearing is installed on described adapter plate, the bottom of described S. A. is arranged on described the 3rd bearing, 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 and described baffle plate is pressed on the below of described the 3rd bearing.
Preferably, described pressing plate is annular pressing plate.
Preferably, be provided with rotating push rod on the outer wall of described column spinner.
Preferably, described rotating push rod and described column spinner are hinged, and are provided with claw on described column spinner, and when described rotating push rod is threaded to when paralleling with described column spinner, described rotating push rod is fixed in described claw.
Because technique scheme is used, the present invention compared with prior art has following advantages:
During due to electric crane work of the present invention, suffered diametral load and axial force shared by clutch shaft bearing and the second bearing, therefore, even when column spinner is longer, the stability of this electric crane still can be guaranteed, simultaneously, the electric crane of this structure rotation flexibility and reliability, safe.

The specific embodiment
The invention will be further described below in conjunction with embodiment shown in the drawings:
Embodiment one: referring to accompanying drawing 1 to shown in accompanying drawing 3.
A kind of rotary electric crane comprises that column, an end are fixedly connected on the arm on vertical columns, and column comprises fixed leg, the column spinner that connects, and arm is fixedly connected on pivot arm;
The inside of pivot arm is fixedly installed the first nest with centre hole, second nest of level, is fixedly installed S. A. in the first nest, the second nest, and S. A. is stepped shaft, and the lower end of S. A. reaches the outside of the lower end of column spinner;
Fixed leg inside is fixedly installed bearing seat, bearing seat is arranged on the interface that fixed leg and column spinner connect, clutch shaft bearing is installed on bearing seat, the top of clutch shaft bearing is provided with the second bearing, be provided with annular pressing plate between clutch shaft bearing and the second bearing, the upper end of the second bearing is pushed against the below of the second nest, and clutch shaft bearing, the second bearing match with S. A. respectively the rotatable top that is arranged on fixed leg of column spinner;
Be provided with the adapter plate with centre hole in fixed leg, adapter plate is positioned at the below of bearing seat, the 3rd bearing is installed on adapter plate, the bottom of S. A. is arranged on the 3rd bearing, 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 and baffle plate is pressed on the below of the 3rd bearing;
Be provided with the rotating push rod that is hinged with column spinner on the outer wall of column spinner, be provided with claw on column spinner.
When rotary electric crane, rotating push rod is screwed off and promotes rotating push rod, column spinner driven rotary axle rotates, and stops promoting rotating push rod when arm is threaded to desired location; When not needing rotary electric crane, then the rotation rotating push rod is fixed on rotating push rod in claw to paralleling with column spinner.The diametral load that electric crane is subject to and axial force are shared by clutch shaft bearing and the second bearing, so this electric crane has higher safety, stable, flexibly, reliable.
