Description
Technical field
What the present invention relates to is a kind of repair method that is used for lorry body, adopts the maintenance mode of Detroit automation, makes by the acceptance maintenance of being back to back of maintenance workpiece, belongs to conveyer logistlcs technology field.
Background technology
Existing car body service technique is the fixedly inspection rack position maintenance workpiece that utilizes the maintenance storehouse, finishes whole technology maintenance process.After finishing, maintenance goes out car simultaneously.Maintenance quantity is decided with the quantity of fixed way position, and per tour goes out car once (per tour was in 7 hours).Go out the car actual with the longest being as the criterion of repair time, inspection rack position practical efficiency is lower.Increase task as need, can only increase work shift or add the general overhaul warehouse area.Simultaneously, each Knock-Down Component in maintenance process (as bogie truck etc.) needs to focus on the somewhere unification from each below, position and enters accessory maintenance storehouse, and good accessory needs to disperse be transported to each below, fixed way position from the somewhere and assembles, and carries chaotic.
Summary of the invention:
The objective of the invention is to propose a kind of lorry body repair method, realize the orderly Detroit automation of lorry body maintenance.Effectively solve in the prior art existing maintenance unordered, carry problem such as confusion.Improve the quality of whole lorry body maintenance and the utilization ratio of platform position.
Technical solution of the present invention: the lorry body repair method, its step is
One, the body of waiting to repair enters the pre-part inspection of maintenance storehouse car body district outside the storehouse, carries out the car body rust cleaning; Car body cleans; Car body preliminary examination, information of vehicles read in; Measurement wait to repair hook height in the body and side bearing clearance and information imported computing machine; Pull down effect hook uncoupling rod bracket in the body of waiting to repair, cut off the hook uncoupling rod bracket, on draw round pin etc.; Decompose coupler buffering device, car body separates with bogie truck;
Two, finish the conveying of whole locomotive body station with paces formula car puller; Enter the slow maintenance of hook district, maintenance storehouse respectively with the coupler buffering device that decomposes with bogie truck that car body decomposes, overhaul in bogie truck maintenance district in maintenance storehouse;
Three, car body separates with bogie truck by the aerial positioning machine of movable type car body is sling, and enters maintenance car body resolver, storehouse, carries out the car body upset and checks and divide fault, required accessory information input computer; Wait to repair body body center plate and valve module decomposes; Decompose brake cylinder, cut-out cock, dirt collector etc.; Simultaneously separating component enters maintenance storehouse accessory respectively and adds and repair the district, carries out the accessory maintenance, has portable aerial positioning machine to finish the conveying of common interdigit in whole decomposable process; Knock-Down Component is easy to operate, the car body upset can be carried out;
Four, parts decompose finish after, steel structure of car body has the multifunctional car body transport overhead traveling crane to be delivered to steel structure of car body maintenance district, maintenance storehouse to carry out the repair welding of steel structure of car body, hot accent, rivet welding, change door operation; Disqualified upon inspection is reprocessed;
Five, after component inspection finished, the multifunctional car body transport overhead traveling crane was delivered to maintenance storehouse test area with good car body, by the aerial positioning machine of movable type car body was sling and was carried out the assembling of body center plate and valve module; Assembling brake cylinder, cut-out cock, dirt collector etc., the car body check.Required accessory adds the center of repairing by accessory and puts in place by the input information conveying;
Six, after detail assembly finished, bogie truck entered the assembly or fitting table position by cooresponding car body, finishes the assembling of car body and bogie truck; The district carries out the slow assembling of hook in the check assembling of maintenance storehouse; Car load check, brushing vehicle paint mark; The vehicle performance test; Single car test; The conveying of whole station has paces formula car puller to finish.
Advantage of the present invention:
1. solved the problem of overhaul efficiency with better simply process layout and special process equipment, can
Utilize original space for maintenance, make maintenance technology more reasonable, cost is low, manufacturing, use, easy for installation.
2. original fixed way position maintenance mode is by 30 fixed way positions, and it is 30/class (7 hours meters) that per tour goes out the car number.Flow system is carried out technology according to existing platform figure place and is decomposed, and maintenance rhythm is about/8min, i.e. per tour goes out the car number and is about 52.Efficient significantly improves.
3. the maintenance mode of original fixed way position, the conveying of parts is from the face to the point, puts the conveying of face, and is chaotic.The flow system parts decompose assembling in the fixed position, realize the conveying of point-to-point, and whole conveying is reasonable, and is convenient.
4. the present invention is the maintenance that is used for lorry body, and its being back to back of car body of realization is overhauled.
