Abstract
The invention relates to a lean wheel structure of a gantry traveling crane. The lean wheel structure is mounted at the edge of the traveling crane and is tightly abutted against an I-beam walking frame. The lean wheel structure comprises a lean wheel carrier, a first lean wheel axle, a first lean wheel, a second lean wheel axle, a second lean wheel and two adjusting threaded rods, wherein the first lean wheel axle is vertically mounted on the lean wheel carrier, and the first lean wheel is movably nested on the first lean wheel axle and is in rolling-contact connection with the middle part of the I-beam walking frame; the second lean wheel axle is transversely mounted on the lean wheel carrier, and the second lean wheel is movably nested on the second lean wheel axle and is in rolling-contact connection with the upper edge of the I-beam walking frame; and the two adjusting threaded rods are respectively mounted on the lean wheel carrier and are respectively in abutting-against connection with the first lean wheel. The lean wheel structure of the gantry traveling crane, disclosed by the invention, has the advantages that the left/right leaning force is strong, thus the traveling crane can be prevented from generating a left/right offset; the upward/downward leaning is additionally provided, thus the traveling crane can be effectively prevented from jumping up and down; and the adjusting threaded rods are additionally arranged, and the first lean wheel axle and the first lean wheel are adjustable, so that the left/right leaning force is guaranteed.
Description
Technical field
The present invention relates to a kind of handling appliance, the roller structure of particularly a kind of gantry driving.
Background technology
At present, plating line driving in gantry all adopts roller to proofread and correct the road location, makes it be unlikely to deflection.Also can regulate the slight position skew of driving after the long-time running through the degree of tightness roller.But in gantry bridge crane structure of leaning on the rack-and-gear location, there is a kind of like this problem: when the driving operation; Be by be contained on the capable walking frame tooth bar be contained in gear in the driving mesh realize pinpoint; When there were certain wear in tooth bar or gear, slippage phenomenon will appear.Common roller can only carry out single being close to of a direction and avoid left and right sides deflection, keeps away the bob of unavoidable driving and the location inaccuracy that causes.
Summary of the invention
The object of the invention is to overcome the problems referred to above that prior art exists, the roller structure that provides the gantry that all can locate up and down about a kind of to drive a vehicle.
The objective of the invention is to realize like this: the roller structure of a kind of gantry driving is installed in the driving edge and near the capable walking frame of I-beam section; Comprise roller frame, the first roller axle, first roller, the second roller axle, second roller and adjusting screw(rod); The first roller axle vertically is installed on the roller frame, and the first roller activity is nested on the first roller axle and with the middle part rolling touch of the capable walking frame of I-beam section and links to each other; The second roller axle laterally is installed on the roller frame, and the second roller activity is nested on the second roller axle and with the upper edge rolling touch of the capable walking frame of I-beam section and links to each other; Adjusting screw(rod) totally two be installed in respectively on the roller frame and conflict with the first roller axle respectively and link to each other.
Be provided with two arbor wheels between described first roller and the first roller axle, first roller rotates around the first roller axle through two arbor wheels; Be provided with an arbor wheel between described second roller and the second roller axle, second roller rotates around the second roller axle through this arbor wheel.
Described roller frame bottom is provided with a horizontal U-lag, and the described first roller axle vertically is installed in two trough rims of this U-lag, and described first roller is horizontally installed in this U-lag.
The last trough rim outside of the U-lag of described roller frame is provided with oval-shaped groove; The upper end of the described first roller axle is provided with oval cap; This ellipse cap is inlaid in the oval-shaped groove; And the long axis length of oval cap is less than the long axis length of oval-shaped groove, makes the first roller axle can be along the horizontal sway of oval-shaped groove.
The outside face of described first roller axially curved.
Be with axle sleeve on the described second roller axle, this axle sleeve and roller frame are fixedly linked.
The roller structure of gantry of the present invention driving has following advantage and characteristics owing to adopted above technical scheme:
1, the dynamics that leans about is strong, can prevent to squint about driving from producing.
2, except that about lean, increased up and down and leaned, can effectively prevent the bob of driving a vehicle.
3, increased adjusting screw(rod), the first roller axle and the first roller scalable lean dynamics about assurance.
Description of drawings
