Abstract

The utility model provides a column rotary crane comprises a column, a rotary shaft, a rotary arm, a supporting arm, a travelling trolley and a motor, wherein the rotary arm is rotatably connected with the column through the rotary shaft. The column rotary crane is characterized in that the supporting arm is fixedly arranged on the rotary arm close to the rotary shaft, a rotary block is fixedly connected to the bottom of the supporting arm, a rolling bearing is arranged on the side of the rotary block, a circular first slide rail is arranged on the column corresponding to the rolling bearing, and the rotary block rotates along the first slide rail through the rolling bearing. The rotary arm is joist steel. A horizontal second slide rail is arranged on a lower wing plate of the rotary arm, the travelling trolley moves along the second slide rail horizontally, a hook is connected to the travelling trolley through a pulley, the motor is further fixedly arranged on the travelling trolley, and the motor drives the travelling trolley to move. The supporting arm and a sliding system between the supporting arm and the column are uniquely arranged, so that the supporting arm can improve the maximum lifting weight of the whole crane, and can maintain the whole machine stable in structure during rotation.

Description

A kind of pillar (rotary, revolving) crane

Technical field

The utility model relates to a kind of hoisting crane, relates in particular to a kind of turning crane.

Background technology

Mostly the crane using in factory building in prior art is gauntry crane, and gauntry crane has weighs greatly, the advantages such as Stability Analysis of Structures, but gauntry crane can only straight line moving, encounter and need the object of 90 degree displacements just helpless, and gauntry crane occupation of land is huge, operation is got up very heavy.Therefore, need a kind of crane, this crane can complete various non-rectilinear lifting tasks flexibly.

Utility model content

In order to solve the above problem existing in background technology, the utility model provides a kind of pillar (rotary, revolving) crane, and this hoisting crane can rotate by 360 deg, has occupation of land little, assembles the advantages such as efficient and convenient, Stability Analysis of Structures.

For achieving the above object, the utility model adopts following technical scheme:

A kind of pillar (rotary, revolving) crane, comprise column, S. A., spiral arm, hold-down arm, walking dolly and electrical motor, described spiral arm is rotaryed connection with column by S. A., on spiral arm, nearly S. A. place is fixed with hold-down arm, hold-down arm bottom is fixedly connected with swivel block, swivel block sidepiece is provided with antifriction-bearing box, on column, the position corresponding with antifriction-bearing box is provided with the first slide rail of annular, swivel block rotates along the first slide rail by antifriction-bearing box, described spiral arm is I-beam section, on the lower wing plate of spiral arm, be provided with the second slide rail of level, walking dolly is along the second slide rail parallel motion, on walking dolly, by pulley, be connected with suspension hook, on walking dolly, be also fixed with electrical motor, direct motor drive walking dolly moves.

On the web of described spiral arm, be horizontally disposed with suspension line, the hoist cable of connecting shackle is suspended on suspension line.

S. A. place is provided with rotating machine, and rotating machine is by driving S. A. to drive spiral arm to rotate.

On electrical motor, be connected with controller.

The beneficial effects of the utility model are:

1, can 360 ° of rotations, have and take up an area the advantages such as few, simple in structure, easy to use

2, uniqueness is provided with the sliding system between hold-down arm and hold-down arm and column, and this hold-down arm can improve the maximum lifting weight of whole hoisting crane, and can keep when rotated the Stability Analysis of Structures of whole machine.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further illustrated

Fig. 1 is the structural representation of the utility model embodiment 1;

The specific embodiment

Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is further described:

Embodiment 1

As shown in Figure 1, a kind of pillar (rotary, revolving) crane, comprise column 1, S. A. 12, spiral arm 2, hold-down arm 3, walking dolly 8 and electrical motor 7, described spiral arm 2 is rotaryed connection with column 1 by S. A. 12, on spiral arm 2, nearly S. A. 12 places are fixed with hold-down arm 3, hold-down arm 3 bottoms are fixed with swivel block 5, swivel block 5 sidepieces are provided with antifriction-bearing box 6, on column 1, the position corresponding with antifriction-bearing box 6 is provided with the first slide rail 4 of annular, swivel block 5 rotates along the first slide rail 4 by antifriction-bearing box 6, described spiral arm 2 is I-beam section, on the lower wing plate of spiral arm 2, be provided with the second slide rail 9 of level, walking dolly 8 is along the second slide rail 9 parallel motions, on walking dolly 8, by pulley, be connected with suspension hook, on walking dolly 8, be also fixed with electrical motor 7, electrical motor 7 drives walking dolly 8 to move.

On the web of described spiral arm 2, be horizontally disposed with suspension line 11, the hoist cable of connecting shackle is suspended on suspension line 11.On described electrical motor, by electric wire, be connected with controller 10.S. A. place is provided with rotating machine (not shown), and rotating machine is by driving S. A. to drive spiral arm to rotate.

Controller 10 is by controlling electrical motor and drive motor, thus the control rotation of spiral arm and the movement of walking dolly.

The advantage of the utility model maximum is the sliding system between hold-down arm and hold-down arm and column, and this hold-down arm can improve the maximum lifting weight of whole hoisting crane, and can keep when rotated the Stability Analysis of Structures of whole machine.
