Abstract

The utility model relates to a crane frame with fully rotating beam which is a device collocated a gantry crane and used for material hoisting work. The utility model is characterized in that the upper part of a column is provided with a vertical arm; the upper end of the column is connected with a drawing plate; the lower end of the column is abutted and matched with the orbital plane of the column by a pair of rollers. The crane frame is provided with hand, pneumatic, and electric rotary arm types, and the pneumatic and electric rotary arms are realized by that a power machine arranged at the lower part of the vertical arm is meshed with a shaft gear and the gear of a rolling wheel extended out of the output end of a reducer casing through the reducer casing. The frame which adopts a uniform strength beam design, and a fully rotating beam structure has the advantages of light weight, material saving, and wide work range, a plurality of rotary arm types, strong applicability, and flexible operation.

Description

Crane structure with fully rotating beam

Fixed column type arm full circle swinging hoist frame is a kind of device that the configuration hoist crane is used for the material lifting operation.

Generally in 300 °, its lifting operation scope is restricted for existing Pillar-fixing Type Slewing Crane frame, the rotating range of arm.The Full Rotary hoist frame of another arm, pivoted arm adopts big specification uniform cross section steel I-beam, and the sectional dimension of beam is by the design of full beam maximum weighted point, owing to beam head and afterbody stressed difference, in fact increased the use amount of material, and the load of hoist frame is strengthened.In addition, engine adopts single gas, electric mode, uses restricted by field condition and other related factors, lacks alerting ability.

The purpose of this utility model is to overcome weak point of the prior art, and provides a kind of constant strength beam structure, arm full circle swinging, the hoist frame of hand, electricity, the multiple power mode of gas.

In order to achieve the above object, the engineering factor solution that the utility model adopts is: in the hoist frame of mainly being made up of column and swivel arm, the top of column is provided with a upright arm in parallel, the upper end of upright arm connects an end of an arm-tie, the other end of arm-tie is provided with axis hole, the vertical dead axle that stretch out its axis hole and column upper end is connected, and a pair of scroll wheel is installed in the bottom of upright arm, and its wheel radial end face abuts on the track road face on the column.The side of upright arm connects the swivel arm of horizontal, and the top outer end of its arm is connected a pull bar with the top of upright arm.

When this hoist frame adopts mechanical power pivoted arm mode, the bottom of upright arm is provided with the power whirling arm mechanism, its composition is that a drop-gear box is installed in upright arm bottom, engine is installed on the drop-gear box, the drop-gear box mouth stretches out a shaft gear, the bottom of scroll wheel is offered and is had tooth, shaft gear to be installed between two scroll wheels, the tooth engagement on its tooth and the scroll wheel.

When the engine of this hoist frame adopted air motor, its source of the gas was supplied with by the wind duct, dead axle center that is arranged in the column, and install the upper end in wind hole can turn to elbow.When engine adopted electrical motor, power supply was by the slip ring power supply input media input that is arranged between arm-tie and the column upper end.

This hoist frame is owing to adopted equal strength beam arm full circle swinging structure, and Rack Body is light, and materials are economized, and scope of work is wide, and design has three kinds of modes of manual, pneumatic, electronic pivoted arm, and comformability is strong, uses flexibly.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the front view of this hoist frame.

Fig. 2 is the birds-eye view of this hoist frame.

Fig. 3 is the A-A section-drawing of Fig. 1.

Fig. 4 is the C-C section-drawing of Fig. 3.

Fig. 5 is the B-B section-drawing of Fig. 2.

By Fig. 1 and Fig. 2 as can be known, this hoist frame is by column 1, track 4 on it and the roller devices that is mated, and the upright arm 5 parallel with column connects the arm-tie 8 of column and upright arm, the pivoted arm 6 of upright arm side and pull bar 7 compositions such as grade above it.Column 1 adopts sheet material or channel-section steel to abandon and is welded into post, also can select the tubing with moment of inertia for use, and pivoted arm 6 is an I-beam section shape, outside cylinder lever connecting rod 7 above the pivoted arm, and the other end of pull bar is connected the top of upright arm 5.When adopting the mechanical power pivoted arm, drop-gear box 3 is installed in the bottom of upright arm 5, connects electrical motor on the drop-gear box, or air motor 2.

Fig. 3 and Fig. 4 have provided shaft gear that the drop-gear box mouth stretches out and scroll wheel and column rigging position and the structure between getting on the right track.Shaft gear 11 is arranged between two scroll wheels 10, the engagement of the tooth of its tooth and scroll wheel bottom, and scroll wheel top is the face of cylinder, its cylinder end abuts on the track 4 road faces.

Fig. 5 has shown the gas of this hoist frame, electric input structure.When adopting air motor as engine, gas is supplied with through the rotatable elbow 9 of end mounted thereto by wind duct, 12 center of the dead axle in the column; When adopting electrical motor, slip ring power supply input media 13 is installed between arm-tie 8 and column 1 upper end as engine.
