The specific embodiment
Embodiment
As shown in Figure 1, long and two-short dash line is represented line delivery, and the direction of arrow is represented the throughput direction of line body, and whole line body lower floor is used for load transport trolley and workpiece, and the unloaded dolly in upper strata returns, and forms an on-cycle delivery system.The Design of Steel Structural Element Sections of individual layer roller bed conveying line is as shown in Figure 2; The steel structure of double-deck roller bed conveying line is as shown in Figure 3; Individual layer is connected part with bilayer and connects with jacking system; The birds-eye view of this jacking system is as shown in Figure 5, and jacking system is made up of steel structure and screw elevator 5, and detail will be described below.
Heavy roller bed frame is installed on the portal frame, carries the dolly of bogie truck erecting by overhang and on heavy roller conveyor, carries.Said heavy roller conveyor, its cross section have three kinds of unpowered roller bed frame cross sections, power roller bed frame cross section and frictional power roller bed frame cross section.
As shown in Figure 7, unpowered roller-way cross section comprises H shaped steel 9, roller 10, axle 11, bearing 12, riser 13.Here, we combine roller 10, axle 11, bearing 12 to be called unpowered roller.Riser is fixed by bolts to a side of H shaped steel, whenever leaves at a distance from an end distance according to design-calculated intensity needs and fixes once, and is as shown in Figure 9; Each symmetry has the hole of placing bearing on riser and the H shaped steel; Hole size and bearing size adapt, and have groove on the bearing, and have clip to be fixed; Axle is fixed roller through key, and the both wings of axle are installed on the bearing of two symmetries.
Shown in figure 10, power roller-way cross section comprises H shaped steel 9, roller 10, axle 11, bearing 12, riser 13, sprocket wheel 14.Here, we lump together roller, axle, bearing, chain wheel set and are called live roll.The difference in power roller-way cross section and unpowered roller-way cross section is that power roller-way cross section is equipped with drive sprocket on its axle.
As shown in Figure 6, frictional power roller bed frame cross section comprises H shaped steel 9, roller 10, axle 11, bearing 12, riser 13, sprocket wheel 14, friction lining 15, spring 16.Here, we combine roller 10, axle 11, bearing 12, sprocket wheel 14, friction lining 15 to be called friction roller.Riser is fixed by bolts to a side of H shaped steel, whenever leaves at a distance from an end distance according to design-calculated intensity needs and fixes once, and is as shown in Figure 9; Each symmetry has the hole of placing bearing on riser and the H shaped steel, and hole size and bearing size adapt, and have groove on the bearing; And have clip to be fixed, and axle is fixed roller through key, and axle mounting is on the bearing of two symmetries; One end of axle is equipped with sprocket wheel, is friction lining between sprocket wheel and the axle, and the friction coefficient size of friction lining is according to design demand; The friction force that promptly guarantees friction lining is smaller or equal to friction force allowable, spring be used to retrain sprocket wheel axial motion.Under general conveying situation, friction lining plays driving torque, when dolly is obstructed, limits roller work moment because of the running resistance square surpasses, and the result is skidded friction lining.
Be intensity and the load-carrying capacity of strengthening whole conveyer, put on a solid drawn pipe in a side of H shaped steel with a reinforcement screw rod and reinforcement steel pipe 22, two ends are separately fixed at two planes up and down of H shaped steel about the screw rod, and are shown in figure 10.
Actuating device is installed on the H shaped steel, and is shown in figure 16, and drive motor 26 drives drive sprocket 14 through gyrostat 25 and rotates.
Below the design and installation method of comprehensive this heavy type roller conveyor of narration.
This heavy type roller bed frame is installed on the portal frame, according to the intensity of roller bed frame and the weight of workpiece, calculates its deflection through finite element analysis method, thereby designs the distance between the portal frame.For strengthening the intensity and the load-carrying capacity of roller bed frame, whenever be spaced a distance, be equipped with in a side of H shaped steel and strengthen screw rod 22.
Unpowered roller is installed on the roller bed frame according to design demand equably; According to the size of dolly 8, every interval one end distance leaves, and unpowered roller is replaced to powered rollers, guarantees promptly that dolly 8 is dynamic all the time to be fed forward.Drive motor is installed on the H shaped steel.In line delivery, dolly need amass the position of putting, and powered rollers is replaced to the frictional power roller, and is stuck to prevent motor.
Roughish plane is made to guarantee friction force in the plane that dolly contacts with roller, and the side of dolly is equipped with limited roller 21.
Like Fig. 4, shown in Figure 5, four screw rods 6 are fixedly mounted on the portal frame, and there is driven sprocket 27 upper end of screw rod; Driven sprocket and screw rod are connected; Driven sprocket is by drive sprocket 28 driven in rotation, and drive sprocket and drive motor 28 are installed in portal frame one side, and screw elevator is installed on the screw rod.
Because existing manufacturing technology, after four screw rods of screw elevator create, and straight under the nonideality; Even after the alignment; In its working process, also can bend, during bent screws, can drive the skew of nut occurrence positions; This just makes elevator unstable in lifting process, even causes elevator generation stuck phenomenon.So on elevator, use Y-piece, on nut, done square convex.Like this,, cause nut to be subjected to displacement, also the elevator stuck phenomenon can not take place even when screw rod deforms.When initial designs, we are designed to cliding friction with slide and fork handle, but because of coefficient of sliding resistance is 0.2, when causing fork handle to be subjected to displacement with nut, friction force is bigger, DeGrain.Make fork handle and slide into friction of rolling now, friction coefficient has only 0.01, promptly on the slide hole around be evenly equipped with ball hole, be placed with ball in the ball hole.
Also there is a problem in actual use in screw elevator according to the method for top passage record is made, and that is exactly after nut is installed in screw rod; During initial the installation; Four nuts are corrected on a horizontal surface, but after screw rod bent in the process of rotation, four nuts were just not necessarily on a horizontal surface; Y-piece is contacted or the line contact with the nut origination point, cause nut or Y-piece to damage.This device has been done trapezoidal convex in bottom, nut and the Y-piece contact portion of Y-piece on nut, trapezoidal convex is shown in figure 17.When four nuts were not on a horizontal surface, shown in figure 19, contacting between nut and the Y-piece remained the face contact.
Need to prove; The opening direction of four Y-pieces on the screw elevator is respectively towards four different directions; The reason of doing like this is when nut is subjected to displacement; Y-piece can be subjected to displacement on four direction, if the Y-piece opening direction has two or more identical, its effect will weaken so.
