Abstract

The utility model relates to a crane which has an electrical swinging arm and a column swing lever, which belongs to hoisting transport machinery and is suitable for transportation on production line, loading and unloading of major equipment die assembly, loading and unloading goods on storage and wharf. The utility model is characterized in that the section of the swinging arm is Y-shaped or Pi-shaped, the section of the vertical arm is a box type, and the vertical arm is connected with a radial arm device C through a twist shaft, the tread wheel C6 on the radial arm device C contacts with the rail on the upright post. When the section of the swinging arm is Pi-shaped, the electric hoist is arranged at the middle of the swinging arm, the two ends drive the speed reducing gear by a dual rail motor; the connecting plate which is arranged on the electric hoist and the lever which crosses the crane frame is connected with the speed reducing gear by bolts, the driving wheel and driven wheel which are arranged on the reducer are positioned on the railway of the swinging arm to realize double track operation. The utility model has the advantages that the crane can bear load with strong rigidity uniformly, when the radial arm device is connected with the vertical arm by a twist shaft, the tread wheel and the railway of the radial arm device take on a line contact, thus the swinging arm can work smoothly and bear force evenly.

Description

A kind of electronic pivoted arm, Pillar-fixing Type Slewing Crane

Technical field

The utility model relates to a kind of handling machinery.It is to adopt electronic pivoted arm, Pillar-fixing Type Slewing Crane.Be useful on automobile, trac., the various manufacturing line; The loading and unloading of main equipment such as compression machine, injection machine mould, frock; Use in the loading and unloading of warehouse, goods yard, station, harbour and other items.

Background technology

The pivoted arm of the Pillar-fixing Type Slewing Crane of producing, upright arm all adopt i-beam structure at present, and spiral arm device and upright arm are rigidly connected by bolt.Shortcoming is that during bearing load, stress differs greatly because pivoted arm, upright arm adopt I-beam section, and horizontal stiffness is poor, and the wheel tread of stepping in the spiral arm device is a convex, and stepping between wheel and the track is to contact, and the part of contact surface is pushed powerful excessive, poor, the easy deformation of load-carrying capacity.

The utility model content

In order to overcome the shortcoming of original technology, the purpose of this utility model is that the constant strength beam structure is all adopted in the cross section of a kind of pivoted arm of design, upright arm, and stepping on wheel tread is column type, and upright arm and spiral arm device adopt the electronic pivoted arm of articulated manner bonded assembly, pillar (rotary, revolving) crane.

For realizing the purpose of this utility model, take following technical scheme, a kind of electronic pivoted arm, Pillar-fixing Type Slewing Crane are made up of by screw and the upright arm 2 of spiral arm device C bonded assembly the pivoted arm 3 of column 1 and portion mounted thereto and top and pivoted arm 3 assembly weldings, bottom, Y type or ∏ type are adopted in the cross section that it is characterized in that pivoted arm 3, the cross section of upright arm 2 is a box, and upright arm 2 is connected with spiral arm device C by twisted axis C7.Stepping on wheel C6 on the spiral arm device C contacts with track 5 on the column 1.When the cross section of pivoted arm 3 is the ∏ type, electric block 4 is placed on the centre of pivoted arm 3, two ends drive speed reduction gearing 7 by double track motor 6, the connecting panel 11 that is installed on the electric block 4 is connected with speed reduction gearing 7 with the pull bar 10 usefulness bolts that pass vehicle frame 12, driving wheel 8, the follower 9 installed on the speed reduction gearing 7 are seated on the track of pivoted arm 3, realize the two-orbit operation.

Advantage of the present utility model

Because Y type or ∏ type are adopted in the cross section of pivoted arm, upright arm adopts box-structure, so bearing load uniformly, rigidity is strong; The spiral arm device is with after upright arm is connected by twisted axis, steps on wheel and presents line with spiral arm device track and contact, thereby make pivoted arm stable working, stressed even.When pivoted arm adopted the ∏ cross section, electric block was placed in the middle of the pivoted arm, can weather proof, and, can improve lifting altitude than monorail crane when operating altitude fixedly the time.

Among the figure: 1, column 2, upright arm 3, pivoted arm 4, electric block 5, spiral arm device track C, spiral arm device C1, motor C2, retarder C3, step on wheel cover C4, gear C 5, step on wheel shaft C6, step on wheel C7, twisted axis 6, double track tumbler motor 7, speed reduction gearing 8, driving wheel 9, follower 10, pull bar 11, connecting panel 12, vehicle frame

See Fig. 1, Fig. 2, Fig. 3

The cross section is that the pivoted arm 3 of Y type is connected with column 1, and the upright arm 2 of assembly welding on pivoted arm 3 is connected with spiral arm device C by twisted axis C7, and founding arm 2 is box-structure, and stepping on the spiral arm device C taken turns C6 and contacted with track 5 on the column 1.

See Fig. 4, Fig. 5, Fig. 6

Spiral arm device C is by motor C1 connection reducer C2, meshes with being fixed on the wheel C6 that steps on that steps on the wheel shaft C5 by being installed in the gear C of stepping in the wheel cover C3 4, and spiral arm device C is connected with upright arm 2 by twisted axis C7.

See Fig. 7

Electric block 4 is placed in the pivoted arm 3 that the cross section is the ∏ type, the connecting panel 11 that is fixed on the electric block 4 is connected with the speed reduction gearing 7 that double track tumbler motor 6 drives by vehicle frame 12, pull bar 10, speed reduction gearing 7 drives driving wheel 8, follower 9 rotations, realizes that electric block 4 moves on the pivoted arm 3 of two-orbit.

The specific embodiment

Pivoted arm 3 cross sections are the single track pivoted arm when being the Y type.Step on wheel C6 and rotate by retarder C2, gear C 4 drives during motor C1 work,, found arm 2 and pivoted arm 3 assembly weldings, so the electric block 4 that is installed on the pivoted arm 3 can comprehensive work in 360 degree because spiral arm device C is connected with upright arm 2 by twisted axis C7 along track 5.

Pivoted arm 3 cross sections claim the double track pivoted arm during for ∏.6 work of double track tumbler motor, drive speed reduction gearing 7, driving wheel 8, follower 9 rotations, the connecting panel 11 that is fixed on the electric block 4 is connected with speed reduction gearing 7 by vehicle frame 12, pull bar 10, thereby the electric block 4 that is placed in the middle of the pivoted arm 3 that the cross section is the ∏ type moves on the pivoted arm 3 of two-orbit.
