Abstract
The utility model discloses an escalator armrest belt driving system, which comprises a head revolution part and a central driving part. The head revolution part comprises an armrest belt (3) and a revolution chain roller train (4). The revolution chain roller train (4) is formed by a plurality of revolution chain rollers arranged on the inner side and the outer side of the armrest belt. The central driving part comprises a driving main shaft (1), a friction wheel (2) and an armrest belt (3). The outer circumference of the friction wheel (2) is provided with a first groove (9). The part of the armrest belt (3) in contact with the friction wheel (2) is provided with a projection (10) matched with the first groove (9). The revolution chain rollers (12) arranged on the inner side of the armrest belt are provided with second grooves (11) matched with the projection (10) of the armrest belt (3). Since the groove of the friction wheel is matched with the projection of the armrest belt, the contact area of the friction wheel and the armrest belt is increased. Therefore, the frictional force between the friction wheel and the armrest belt is increased, so that the driving force is increased. The escalator armrest belt driving system can be adapted to escalators with glass wallboards. Due to the adoption of the escalator armrest belt driving system, the lifting height of an escalator is increased to 12~ 18m.
Description
Technical field
The utility model relates to a kind of automatic staircase handrail band drive system.
Background technology
Existing a kind of automatic staircase handrail band drive system; Comprise head rotating part and middle part drive part; Described head rotating part comprises handrail and revolution chain roller set, and described revolution chain roller set is made up of a plurality of handrail revolution chain rollers inboard and outside that are located at; Described middle part drive part comprises driving main shaft, friction wheel and handrail; When rise of escalator>during 12m, propulsive effort is just inadequate, is difficult to guarantee that handrail moves normally.Prior art solutions normally adopts the handrail drive system that a kind of middle part friction wheel drives and the head gyrostat is formed, or adopts a kind of in addition handrail drive system of direct head installing drive wheel.But the problem that exists is: above two kinds of structures are owing to the structural relation of head gyrostat and driving wheel on head, and its oad is bigger, and the escalator that only is fit to common band inclination handrail uses, and are not suitable in the escalator of band glass wallboard, using.
Summary of the invention
The utility model technical matters to be solved is: provide a kind of hoisting depth that can in the escalator of band glass wallboard, use to reach the automatic staircase handrail band drive system of 12 ~ 18m.
The utility model addresses the above problem the technical scheme that is adopted: a kind of automatic staircase handrail band drive system; Comprise head rotating part and middle part drive part; Described head rotating part comprises handrail and revolution chain roller set, and described revolution chain roller set is made up of a plurality of handrail revolution chain rollers inboard and outside that are located at; Described middle part drive part comprises driving main shaft, friction wheel and handrail, and the excircle of described friction wheel is provided with first groove, and the part that described handrail contacts with friction wheel is provided with the convexity that is complementary with first groove; Described be positioned at the inboard revolution chain roller of handrail be provided with handrail on second groove that matches of convexity.
As preferably, described first groove, second groove and protruding cross-sectional plane are trapezoidal.
Compared with prior art; The advantage of the utility model is: because the groove of friction wheel matches with the convexity of handrail; Increased the area of contact of friction wheel and handrail; Increased friction force, made propulsive effort increase, this handrail drive system can have been used and hoisting depth is increased to 12 ~ 18m in the escalator of band glass wallboard.
Description of drawings
Fig. 1 is the structural representation of the utility model automatic staircase handrail band drive system;
Fig. 2 is the cutaway view of middle part drive part in the utility model automatic staircase handrail band drive system;
Fig. 3 is for being positioned at the cutaway view of the inboard revolution chain roller of handrail in the utility model automatic staircase handrail band drive system;
Fig. 4 is the enlarged drawing of A portion.
Among Fig. 1-4: 1, driving main shaft, 2, friction wheel, 3, handrail, 4, revolution chain roller set; 5, bearing pin, 6, bearing support, 7, tie bolt, 8, Armrest guide rail; 9, first groove, 10, convexity, 11, second groove, 12, the inboard revolution chain roller of handrail.
The specific embodiment
Embodiment to the utility model further describes below in conjunction with accompanying drawing.
Shown in Fig. 1-4; The utility model automatic staircase handrail band drive system; Comprise head rotating part and middle part drive part; Described head rotating part comprises handrail 3 and revolution chain roller set 4, and described revolution chain roller set 4 is made up of a plurality of handrail revolution chain rollers inboard and outside that are located at; Described middle part drive part comprises driving main shaft 1, friction wheel 2 and handrail 3; It is protruding 10 that the centre of the inboard of described handrail 3 is provided with, on the excircle of described friction wheel 2 and the excircle that is positioned at the inboard revolution chain roller 12 of handrail be provided with first groove 9 and second groove 11 that matches with convexity 10.
Described first groove 9, second groove 11 and protruding 10 cross-sectional plane are trapezoidal.
Described revolution chain roller is processed by wear-resisting non-lubricating engineering plastics, and single revolution chain roller is installed on the bearing pin 5, and bearing pin 5 is stuck on the bearing support 6, and whole bearing support 6 usefulness tie bolts 7 are fixed in the Armrest guide rail 8 the easy dismounting of such structure.
During escalator operation, driving main shaft 1 is being with friction wheel 2 to rotate, and friction wheel 2 drives handrails 3, because first groove 9 and protruding 10 cooperate, friction wheel 2 increases with the area of contact of handrail 3, and friction force also increases, and makes the propulsive effort increase; At rotating part, being positioned at second groove of establishing on the revolution chain roller 12 of handrail 3 inboards 11 can match with the convexity 10 on the handrail 3, adds the common revolution chain roller that is positioned at handrail 3 outsides, can handrail 3 be play the guiding role actv..The application of this handrail drive system can be increased to 18m with the hoisting depth of the escalator of being with the glass wallboard.
