Abstract

The utility model relates to an ultraheavy plate type conveyer, which alters a conveying chain to be the mode that the utility model is provided with a back stroke supporting roller and increases the number of teeth of a transmission sprocket. That a weak polygon effect which adopts multiple tooth number and a small pitch replaces an intense polygon effect which adopts a conveying chain with a big pitch is realized. The utility model solves the phenomena that a plate type conveyor has oversize noise in the course of operation at a high speed and easily pulsates and creeps at a low speed, and remarkably improves the running speed and the load capacity of the conveyer, with the advantages of small running resistance, long service life, and no need of increasing a back stroke supporting roller.

Description

The extra-heavy duty type apron conveyor

The utility model relates to a kind of apron conveyor.

The application of apron conveyor is commonplace, but generally only is applied in the assembling industry of delivery speed lower (generally being no more than 15 meters/minute), load light (general workpiece weight is no more than 5 tons).Apron conveyor needs the return carrying roller, thereby in return course, friction and interfere very greatly between the connecting portion of carrying platen and the carrying roller, thereby noise is big during high-speed cruising, and low cruise is easy to generate the pulsation creeping phenomenon; Apron conveyor needs the return carrying roller.Bearing capacity is low to have determined that apron conveyor can not be as the auxiliary products of the production assembling of heavy-duty machinery, construction machinery and equipment, and the customs harbour freight container is carried and detected industry requirement and transport steadily, otherwise meeting directly influence the accuracy of detecting instrument signal.

For addressing the above problem, the utility model provides a kind of extra-heavy duty type apron conveyor, but has high-speed cruising, operates steadily, and noise is little, and bearing capacity is big, does not need advantages such as return carrying roller.

For achieving the above object, the technical scheme that the utility model adopted is: the extra-heavy duty type apron conveyor is by messenger chain, conveyer chain, carrying platform, support, the return bracing or strutting arrangement is formed, and bearing pin is a stepped shaft in the conveyer chain chain structure, the built-in two dish needle bearings of bearing roller; One end of stepped shaft has the return carrying roller, return carrying roller built-in bearing, and by back-up ring bearing and spacer are fixed on the bearing pin; Because chain carries carrying roller and the built-in antifriction-bearing box of carrying roller can reduce running resistance greatly, reduce the operation noise; The other end of stepped shaft is milled with symmetrical flat groove, is used for installing clamp, and inside and outside carrier bar connects by clamp.Bush roller chaiin by fine pith between speed reducer output shaft sprocket wheel and the head spindle drive sprocket is connected, correspondingly the number of teeth with the head spindle drive sprocket increases, and guarantee that its number of teeth is the pad several times of the number of teeth of main shaft hinge wheel, be that the conveyer chain chain link is the integral multiple of conveyer chain chain link, it is identical with the main shaft hinge wheel that the phase angle is installed, to guarantee both synchronized operation.Make it to become the faint polygon effect of multiple tooth bars distance by the violent polygon effect of original coarse pitch conveyer chain, noise is excessive when having solved in the prior art apron conveyor high-speed cruising, the easy pulsation phenomenon of creeping during low speed has improved the running velocity and the load carrying ability of conveyer significantly.And it is little to have running resistance, and long service life does not need to increase the advantage of return carrying roller.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

Fig. 1 is conveyer chain chain structure figure of the present utility model;

Fig. 2 is the conveyer chain chain structure figure of apron conveyor prior art;

Fig. 3 is conveyer chain chain type of service figure of the present utility model;

Fig. 4 is apron conveyor conveyer chain chain type of service figure in the prior art;

Fig. 5 is chain drive structure figure of the present utility model;

Fig. 6 is conveyer chain chain sprocket structure figure of the present utility model.

As Fig. 3, Fig. 4, shown in Figure 5, the extra-heavy duty type apron conveyor is by messenger chain 1, conveyer chain 2, carrying platform 3, support 4, and return bracing or strutting arrangement 5 is formed, among Fig. 1 in conveyer chain 2 chain structures bearing pin 6 be stepped shaft, bearing roller 7 built-in two coils needle bearings 8; Replaced the built-in ball-bearing casing 19 of bearing roller in the prior art, to improve load-carrying capacity, (referring to Fig. 2); One end of stepped shaft 6 has return carrying roller 9, return carrying roller 9 built-in bearings 10, and by back-up ring bearing 10 and spacer 11 are fixed on the bearing pin 6; In conjunction with Fig. 3 as seen, because chain carries carrying roller 9, thereby no longer need return carrying roller 18, and carrying roller 9 built-in antifriction-bearing boxs 10, conveyer chain 2 chain when returning carries carrying roller 9 along track 17 operations, compares with the form of bringing the journey carrying roller back to shown in Figure 4, owing to the friction and the interference of not carrying between platen and the return carrying roller, thereby can reduce running resistance greatly, reduce the operation noise; The other end of stepped shaft 6 is milled with symmetrical flat groove among Fig. 1, is used for installing clamp 12, and inside and outside carrier bar 13 connects by clamp 12.Among Fig. 5, bush roller chaiin 1 by fine pith between speed reducer output shaft sprocket wheel 14 and the head spindle drive sprocket 15 is connected, correspondingly the number of teeth with head spindle drive sprocket 15 increases, see Fig. 6, and guarantee that its number of teeth is the integral multiple of the number of teeth of main shaft hinge wheel 16, be that the conveyer chain chain link is the integral multiple that transmits chain link, the installation phase angle is identical with main shaft hinge wheel 16, to guarantee both synchronized operation.Make it to become the faint polygon effect of multiple tooth bars distance by the violent polygon effect of original coarse pitch conveyer chain, noise is excessive when having solved in the prior art apron conveyor high-speed cruising, the easy pulsation phenomenon of creeping during low speed has improved the running velocity and the load carrying ability of conveyer significantly.
