Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of conveying chain of suspension conveyor, concretely relates to a cross type traction chain structure for suspension conveyor. BACKGROUND

[0002] The suspension conveyor is mainly composed of chain, track, lifting appliance, support, transmission seat and adjusting seat and other components, can be widely applied to long-distance conveying, aerial storage, feeding and other processes of workpieces and automatic coating production line, has the advantages of freely selecting conveying line, effectively utilizing space, saving manpower and improving work efficiency. Because the suspension conveyor has the working condition requirements of rising, falling and turning, the traditional chain cannot meet the operation requirements. The universal conveying chain can meet the above working condition requirements, the ring ear of the chain ring of the transverse wheel set of the existing universal conveying chain is connected to the chain shaft of the straight wheel set, based on the need of changing the direction of travel by turning, the space between the ring ear of the chain ring and the transverse wheel is relatively large, and the width of the ring ear is only about half of the spacing of two parallel chain pieces. Not only the structure strength of the whole chain structure is weak, but also there is a relatively large displacement space between the chain shaft of each straight wheel set and the ring ear of each transverse wheel set 90. Although the universal conveying chain can change the direction of travel by turning, because there is a relatively large displacement space between each straight wheel set and each transverse wheel set, the existing universal conveying chain is prone to shaking displacement, collision or friction with the track during movement, which not only affects the stability and smoothness of movement, but also causes wear and tear, damaging the service life and structure strength of the universal conveying chain. The invention patent with the authorized announcement number CN105398747B discloses a universal conveying chain, which includes a plurality of straight wheel sets and transverse wheel sets arranged in a staggered manner, and a link block is connected at the corresponding end of each straight wheel set and transverse wheel set. The link block of the present application is provided with two transverse shaft arms and two straight shaft arms in a cross configuration, directly connecting the straight chain pieces of the straight wheel set and the transverse chain pieces of the transverse wheel set, which can strengthen the structure strength of the universal conveying chain, and make the manufacturing process of the universal conveying chain modularized to simplify the manufacturing process and reduce the cost. The straight wheel set and the transverse wheel set are pivoted on the transverse shaft arm or the straight shaft arm of the link block to change the direction of travel by turning, which can greatly reduce the shaking displacement problem during movement, improve the stability and smoothness of the universal conveying chain. However, the universal conveying chain cannot be connected to the push rod stably and directly, and needs to be connected with the aid of an adapter, which increases the complexity of the structure.
