The specific embodiment
A lot of details have been set forth in the following description so that fully understand the present invention.But the present invention can implement much to be different from alternate manner described here, those skilled in the art can be in the situation that do similar popularization without prejudice to intension of the present invention, so the present invention is not subjected to the restriction of following public concrete enforcement.
As shown in Figures 1 to 7, be the schematic diagram of a kind of embodiment of compound delivery system (hereinafter to be referred as delivery system) with chain drive and friction-driven.
Please refer to Fig. 1, Fig. 4 and Fig. 6, this delivery system comprises track 4-11, load-carrying vehicle 1-2, friction drive device 1-5 and chain drive-belt 6-2.Described load-carrying vehicle is equipped with the road wheel 4-10 matched with described track 4-11, can be along this orbiting motion on described track 4-11, and this load-carrying vehicle 1-2 not only can be by chain drive but also can be by friction-driven on described track.
In Fig. 1, the direction of arrow is the direction of described load-carrying vehicle 1-2 motion.Described load-carrying vehicle 1-2 walking is on described track 4-11.
Described track is the basis of this delivery system, and it is carrying described load-carrying vehicle 1-2 and is providing sense of motion for the motion of this load-carrying vehicle 1-2.This track 4-11 can be divided into friction-driven section 1-4 and chain drive section 1-1 according to the difference of type of drive.Along described load-carrying vehicle 1-2 sense of motion, switching place of friction-driven section 1-4 and chain drive section 1-1 is the first switching place 1-9, switching place of chain drive section and friction-driven section be the second switching place 5-2(as shown in Figure 8).
Please continue to refer to Fig. 1, described friction-driven section 1-4 is provided with described friction drive device 1-5, and described load-carrying vehicle 1-2 relies on the mode of friction-driven to move on described track.This type of drive has the advantages such as low energy consumption, low noise and low pollutions, but propulsive effort is little, and because the friction wheel in described friction drive device 1-5 adopts quality of rubber materials usually, climb so be not suitable for, heavily loaded, high temperature and the more serious occasion of greasy dirt.Therefore, described friction-driven section 1-3 is arranged on working condition zone preferably usually.
Described chain drive section 1-1 is provided with described chain drive-belt 6-2, and in Fig. 1, the position of 1-8 is the position of the traction track that matches with described chain drive-belt 6-2.Described load-carrying vehicle 1-2 relies on the chain-drive mode to move on described track 4-11.It is larger, high temperature resistant that this type of drive has a load-carrying capacity, the advantage such as can work under the poor operating mode such as mist of oil, dust.But this can produce very large noise and impact in motion process due to chain, and lubricating requirement is high, causes oil pollution more serious, and, for guaranteeing the normal operation of chain, also needs to arrange many tightening devices, and integral body is more complicated.Therefore the application of chain conveying line has been subject to certain restriction.Usually, chain drive section 1-1 is arranged in the comparatively severe zone of working condition.
And because the chain-drive cost is high than the cost of friction-driven, and chain-drive designs and installs more complicated.So this delivery system be take friction-driven and is basis, the region division chain drive section 1-1 that can't meet in friction-driven.So both save cost and space, and made design and layout more reasonable, also overcome the limitation that the mode of movement of single type can't overcome.
Described track 4-11 in the present embodiment is ground rail, but the present invention is not limited to one type of ground rail.
Described track 4-11 comprises straight rail (Fig. 1), curved rail (Fig. 2) and track switch, due to demands such as techniques, also is provided with highly different domatic tracks at Special Areas.
In friction-driven section 1-4, described track 4-11 comprises the straight rail of friction and the curved rail of friction.The straight rail section 1-4 that rubs, in the inboard of load-carrying vehicle 1-2 sense of motion, be evenly arranged several linear drives (SL) 1-5, i.e. friction drive device, and described load-carrying vehicle 1-2 reaches the purpose that drives this load-carrying vehicle 1-2 thereby this friction drive device 1-5 can rub.For the continuity that guarantees that described in the driving process, load-carrying vehicle 1-2 moves on described track 4-11, the maximum spacing between two linear drives (SL) must not surpass the total length of the effective friction face of described load-carrying vehicle 1-2 on this load-carrying vehicle 1-2 sense of motion.
In the straight rail section of friction, due to effective friction face of described load-carrying vehicle 1-2, be in the central authorities of load-carrying vehicle 1-2, described load-carrying vehicle 1-2 is stressed more even, center of gravity is positioned at all the time by the perpendicular of described track 4-11, so the phenomenon of described load-carrying vehicle 1-2 rollover can not occur easily, therefore bracing or strutting arrangement can be set.
At the curved rail section 2-1 of friction, near track 4-11, be furnished with curved segment and drive (TL) 2-2, this friction drive device has certain flexibility, and effective friction face that can drive described load-carrying vehicle 1-2 is not parallel to the load-carrying vehicle 1-2 of described track 4-11.Because bending and the described load-carrying vehicle 1-2 of described track 4-11 itself has length, the center of gravity of described load-carrying vehicle 1-2 is the perpendicular departed from by described track 4-11.In addition, because driving (TL) 2-2 itself, curved segment has certain elasticity, it can produce the power perpendicular to the effective friction face of described load-carrying vehicle 1-2 in the process driven, the discontinuity of described load-carrying vehicle 1-2 is easy to the phenomenon that occurs that described load-carrying vehicle 1-2 turns on one's side.
For guaranteeing the stationarity of load-carrying vehicle 1-2, can on load-carrying vehicle 1-2, be provided with the equalizing bar 1-3 extended to described track 4-11 both sides, the balance track 1-7 that walks abreast with described track 4-11 and can support described equalizing bar 1-3 is set, as shown in Figure 2 at the curved rail section 2-1 of friction.
By above content, can be found out, friction-driven is simple in structure, and comformability is good, so application is very extensive.
Please continue to refer to Fig. 1, in chain drive section 1-1, described track 4-11 comprises 4 cun straight rails of chain technique and 4 cun curved rails of chain technique (actual conditions are not limited to 4 cun).At the parallel traction track 1-8 that is provided with of this track 4-11, described chain drive-belt 6-2 with traction track 1-8, coordinate and by chain road wheel 6-3 or/and 7-1 in this traction track 1-8, move.
As shown in Figure 6, on described chain drive-belt 6-2, the 6-1 that cuts somebody's hair is installed, this 6-1 that cuts somebody's hair can hang up the 4-12 that pawls be arranged on described load-carrying vehicle 1-2, thereby along with the motion of described chain drive-belt 6-2 drives this load-carrying vehicle 1-2 motion.
The delivery system of above this friction-driven and chain drive subsection setup had both overcome the limitation of single conveying type, had and had saved to a great extent cost.
Described load-carrying vehicle 1-2 is the carrying tool of this delivery system.According to the characteristics of this delivery system, this load-carrying vehicle 1-2 both need meet can be also can be in the requirement of moving in described track 4-11 under chain drive under the driving of friction drive device 1-5, also to guarantee when two kinds of type of drive conversions self steadily.
