Background technology
At present, internal vapor depot application workshop is when carrying out the vehicle body electrophoresis or spraying paint oven dry, and sled is carried and almost adopted double-chain conveyor to finish all.In when oven dry of spraying paint of carrying out vehicle body, in order to save the energy, the thermal treatment zone of drying oven and the position of heat preservation zone are generally all higher, are higher than the exit position and the entry position of drying oven, this just need respectively dispose a high-temperature lifter at the entrance and exit of drying oven, therefore can increase the initial cost of equipment.In addition, owing to adopted lift, the high-temperature region will be provided with a large amount of control elements and cable, because Temperature Influence, the fault rate of these control modules and cable will raise, thereby the fault rate of induction system also can raise.
Summary of the invention
The purpose of this utility model be to provide a kind of can climb and fall, need not to dispose the novel conveyer of body of a motor car oven dry of lift.
For achieving the above object, the utility model adopts following technical scheme: the novel conveyer of a kind of body of a motor car oven dry, this conveyer comprises the removable carrier chain of die forging, length direction along carrier chain is provided with chain support dolly and carrying vehicle group, carrying dolly and back carrying dolly before the carrying vehicle group comprises, before, be fixed with the carriage that is used to carry the skid that carries the oven dry vehicle body on the back carrying dolly, be hinged with trailer wagon on the preceding carrying dolly, trailer wagon is fixed on the described carrier chain, described carrier chain is arranged on the chain track, and chain track has the flat bank track, vertical turn track and straight rail.
Described chain supports dolly, trailer wagon, preceding carrying dolly and back and carries the roller bearing formula road wheel that the roller bearing formula road wheel of dolly is no bearing cage.
The slewing equipment that is used to be laid on the flat bank track in the drying oven is the halo slewing equipment.
The slewing equipment that is used to be laid on the outer flat bank track of drying oven is the set of rollers slewing equipment.
Described chain track is provided with flexible track in drying oven.
Carrier chain of the present utility model is the die forging knockdown chain, but but die forging knockdown chain not only horizontal rotation but also vertical turn, by the vertical turn track, conveyer itself just can ascents and descents, can save the high-temperature lifter of drying oven outlet and porch, has reduced initial cost, simultaneously, after saving lift, control module and control cable just can be set near the drying oven, the fault rate of induction system is lower.
The utility model chain supports dolly, trailer wagon, preceding carrying dolly and back and carries the roller bearing formula road wheel that the roller bearing formula road wheel of dolly is no bearing cage, roller bearing does not have bearing cage and can avoid bearing to be damaged the road wheel that causes because of retainer corrodes losing efficacy, and prolonged the life-span of equipment.
The slewing equipment that the utility model is laid on the flat bank track in the drying oven is the halo slewing equipment, and the bearing capacity of halo slewing equipment is strong, and environmental suitability is strong, adapts to the adverse circumstances in the drying oven, and fault rate is low.
The slewing equipment that the utility model is laid on the outer flat bank track of drying oven is the set of rollers slewing equipment, set of rollers slewing equipment compact conformation, and cost is low.
The utility model chain track is provided with flexible track in drying oven, flexible track can be avoided producing stress because of expanding with heat and contract with cold of track.
The specific embodiment
In Fig. 1, a kind of body of a motor car oven dry is used novel conveyer system, this system to comprise and is laid on the inner and outside closed circular track of drying oven, is laid with chain on the track, and during work, carrier chain moves in track.Be provided with the import handing-over that joins with skid in the import department of conveyer and roll bed 15, the exit is provided with the outlet handing-over that joins with skid and rolls bed 16.Track comprises straight rail 9, flat bank track 10, vertical turn track 11, flexible track 12 and maintenance rail 13, flat bank track place is provided with the slewing equipment that carrier chain is turned to as level, the slewing equipment that is arranged in the drying oven is a halo slewing equipment 19, and being arranged at the outer slewing equipment of drying oven is set of rollers slewing equipment 20.Halo slewing equipment and set of rollers slewing equipment are prior art, and its concrete structure describes in detail.The import and export climb and fall place of drying oven is provided with vertical turn track 11.Novel conveyer system also is provided with the drive unit 7 that promising carrier chain provides power, and chain stretching device 8 is arranged on the outside of drying oven.
In Fig. 2 ~ 3, carrier chain 1 is the die forging knockdown chain, length direction along carrier chain 1 is provided with chain support dolly 2, also be provided with trailer wagon 3 on the carrier chain 1, carrying dolly 4 before being hinged with on the trailer wagon 3, carrier chain 1 is given preceding carrying dolly 4 by trailer wagon 3 with transmission of power, and preceding carrying dolly 4 is provided with carriage 6 with back carrying dolly 5, carries the skid 18 that is used to carry the oven dry vehicle body on the carriage 6.For skid provides power, the dolly servo-actuated is carried in the back to preceding carrying dolly 4 by trailer wagon 3.Chain supports dolly 2, trailer wagon 3, preceding carrying dolly 4 and back and carries the roller bearing that the roller bearing formula road wheel of dolly 5 is no bearing cage.
