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, as shown in figure 10.
Actuating device is installed on the H shaped steel, and as shown in figure 16, drive motor 26 drives drive sprocket 14 by 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 by 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 the design needs equably; According to the size of dolly 8, every interval one end distance from, unpowered roller is replaced to powered rollers, guarantee 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.
Describe the structure and the principle of jacking system below in detail.
As 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.
Reason owing to 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.
The screw elevator of making according to the method for top passage record, also there is a problem in actual use, 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.Now, in bottom, nut and the Y-piece contact portion of Y-piece, done trapezoidal convex on nut, trapezoidal convex as shown in figure 17.When four nuts were not on a horizontal surface, as shown in figure 19, contacting between nut and the Y-piece remained the face contact.
As Figure 21, shown in Figure 22, prong portion at Y-piece is equipped with forked guide rail 32, riser 36 is fixed by bolts to forked guide rail 32 1 sides, Y-piece 1 can stretch in the square hole of riser 36, between Y-piece and the forked guide rail Z-shaped plate 35 and needle roller 34, the prong bottom of Y-piece contacts with the Z-shaped plate top of falling, and the Z-shaped plate bottom of falling is a needle roller, and the bottom of forked guide rail contacts with trapezoidal convex 29.This improvement project is for a last scheme, and making between Y-piece and the trapezoidal convex is friction of rolling, and loss is little.
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.
