Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The specific implementation scheme of the present invention is that two rail trolleys are used to carry and connect double beams to move on the gantry rail. The driving wheel drives the whole trolley through the motor and the reducer. The upper screw moving platform of the car body is connected to carry double beams, and the lower row of wheels is fixed on the guide rails through spring slide rails, so that the beams can achieve fast and stable longitudinal movement on the gantry. move.

[0015] The present invention is a gantry track trolley for carrying double beams, comprising a gantry frame 1, two trolley tracks 2, two beams 3, two track trolleys 4, and a trolley carrying mobile platform 7 connected to the double beams 3 , Four concave bearing wheels 11, two driving wheels 12, two motors 14, two sets of worm gear reducers ...

Abstract

The invention provides a gantry rail car for bearing double beams. A portal frame is of a square frame structure; and I-shaped car rails are arranged on the two sides of a gantry. The car consists ofrail wheels, a motor and a speed reducer, wherein two wheels are respectively arranged at the front section and the back section of the car for mainly achieving bearing and supporting effects; two middle wheels are driving wheels for providing the operation power; and wheels on the lower row are used for improving the stability. The wheels on the lower row of the car are fixed on guide rails through spring slide rails to improve the stability; the car is mainly used for bearing cross beams and moving; and through driving by the motor, a repeated linear motion of the car is realized. The car islow in chassis, excellent in bearing capacity and high in stability.

Description

technical field [0001] The invention is used for moving the crossbeam on the gantry frame, and in particular relates to a gantry track-type trolley carrying double beams, which belongs to mechanism science. Background technique [0002] The track-type trolley is an important way to realize the carrying and transportation functions. It mainly moves on the track on the gantry, so that the beam it carries quickly approaches the target position in the longitudinal direction. It is difficult for the beam to be fast and stable when moving, which requires an auxiliary connection device to improve efficiency. Using a trolley as a mobile connection device is a convenient and efficient way. [0003] The existing gantry trolley is generally equipped with a single beam and has low motion stability, and cannot meet the requirements of fast, accurate and stable when moving to the target position. Contents of the invention [0004] The object of the present invention is to provide a do...
