Special trolley for friction conveying in automobile body painting workshop

Abstract

The invention discloses a pallet special for friction conveying in an automobile body coating workshop. The pallet comprises walking trolleys, friction balancing beams and a balancing frame. The walking trolleys, the friction balancing beams and the balancing frame are arranged in a protective cover, and two C-type supports are symmetrically arranged at the top of the balancing frame and penetrate through the top of the protective cover. A fixed supporting beam is arranged at the tops of the C-type supports. Openings are formed in the top of the protective cover and used for the C-type supports to penetrate through. The openings are formed in the positions deviating from the vertical center line of the protective cover, so that the trafficability of the pallet is guaranteed, and besides it is effectively avoided that contaminants such as coating mist and sealant enter the protective cover and then directly fall on conveying equipment such as track chains or the balancing beams. The pallet is light, ingenuous in appearance, reasonable in structure, high in balancing performance and capable of being adaptive to special environmental requirements of the automobile body coating workshop, effectively reducing the line stop accidents of a friction line in the coating workshop and improving production quality of stations of paint spraying, gluing, polishing and others.

Description

technical field [0001] The invention relates to the field of mechanized conveying in a car body painting workshop, in particular to a special trolley for friction conveying in a car body painting workshop. Background technique [0002] In the conveying system of the body painting workshop, the painting process chain of the painting workshop often uses the lower chain push rod to mesh with the push head at the bottom of the trolley to drive the trolley to run. The installation height of the conveyor in the paint spraying room directly leads to the bottom of the conveyor being closer to the paint spray tank, which brings difficulties to the design of the paint spray tank. At the same time, the water mist and paint mist in the paint spray room also accelerate the corrosion of chains and tracks; There are many turning curves in the friction conveying system, and the line stop phenomenon caused by the slipping of conveying trolleys and trucks is very likely to occur at the curves...

Problems solved by technology

[0002] In the conveying system of the body painting workshop, the painting process chain of the painting workshop often uses the lower chain push rod to mesh with the push head at the bottom of the trolley to drive the trolley to run. The installation height of the conveyor in the paint spraying room directly leads to the bottom of the conveyor being closer to the paint spray tank, which brings difficulties to the design of the paint spray tank. At the same time, the water mist and paint mist in the paint spray room also accelerate the corrosion of chains and tracks; There are many turning curves in the friction conveying system, and the line stop phenomenon caused by the slipping of conveying trolleys and trucks is very likely to occur at the curves; in the manual work or robot work area of ​​the painting workshop, it has a negative impact on the stability of the car body. Higher requirements to ensure the process quality of the car body; the middle support of the conveying trolley in the body painting workshop is in the form of an upright column, and it is in the middle of the track. Since the friction beam at the bottom of the track and the trolley is in the middle, even if the protective cover is used Protection, in the painting, grinding and other work stations, it is also very easy to cause contamination of the rails, chains, and friction beams, resulting in chain sticking and friction wheel slipping.
