Description
Technical field
The utility model relates to escalator technical fields, and in particular to a kind of compound multiple rows of step driving chain.
Background technique
At present there are mainly two types of the driving methods of escalator, respectively chain drive mode and gear-rack drive side
Formula.
The step chains wherein used in chain drive mode include built-in wheel step chains and external wheel step chains.Built-in wheel ladder
Grade chain replaces the roller in conventional chains also can be simultaneously as the back-up roller of step since idler wheel is located among chain with idler wheel
Wheel.The idler wheel of chain needs and drive sprocket engagement is born outside driving force, while the back-up roller wheel as step and step chains exists
Rolling-operation on guide rail has the bearing (axis of rolling in idler wheel so its surface layer is generally nonmetallic materials and has certain elasticity
Hold or sliding bearing), the driving force that this step chains can carry is lower, generally lower or bearing capacity is smaller in hoisting depth
Escalator and moving sidewalk product in use.
External wheel step chains are typically employed in the biggish heavy-load type escalator of hoisting depth and moving sidewalk, are one
Complete bushroller chain.Step roller is mounted on the outside of chain, and not as the back-up roller wheel of step, roller running roller
Arc turn to section by the unloading guide supporting with elastic surface, mitigate the stress of step roller, it is de- in the straightway roller of operation
Operation is emptied from guide rail, the material of this roller is usually metal, vibration and noise are easy to produce when engaging with drive sprocket,
Although some damping devices are usually arranged on drive sprocket, effect or unobvious, simultaneously because this chain is
Single row configuration, bearing capacity are limited by the union pieces intensity such as carrier bar, pivot pin, and the bearing capacity of chain is also limited
, so and being not applied for the escalator product of super large hoisting depth.
In view of the problems of step chains used in current existing chain drive mode, it is desirable to provide a kind of structure
Simply, the more high and low noise of intensity, run smoothly, be safer, stairs easy to maintain and can be used for super high-altitude escalator
Driving chain.

Together referring to shown in FIG. 1 to FIG. 2, a kind of compound multiple rows of step driving chain, the transmission chain belongs to chain drive
Flowing mode, including the link units of multiple mutual circulations connection, each link units include multiple rows of parallel arrangement of interior chain
Piece 1, multiple rows of parallel setting and the outer chain sheet 2 for connecting corresponding inner chain sheet 1 and at least one set are for hinged multiple rows of parallel arrangement of interior
The pivot pin component of chain piece 1 and outer chain sheet 2.Specifically, the both ends of inner chain sheet 1 and outer chain sheet 2 offer pivot pin through-hole, pivot pin group
Part, which is successively worn, is hingedly connected inner chain sheet 1 and outer chain sheet 2 by being opened in the pivot pin through-hole at 2 both ends of inner chain sheet 1 and outer chain sheet
It connects, constitutes multiple rows of parallel organization.Meanwhile rotation is equipped with multiple rows of parallel arrangement of rolling assembly on pivot pin pivot pin component.
Pivot pin component includes one long pivot pin 3 and two stub axle pins 4, and general existing step chains are one single with three pivot pins
Member, and a step 11 is fixedly installed in the unit, this kind of form is similarly used in the present embodiment.Long pivot pin 3 and short axle
Pin 4 is hinged with double parallel arrangement of inner chain sheet 1 and outer chain sheet 2 respectively, and long pivot pin 3 and the outside of stub axle pin 4 are arranged with axis
Set 5.Long pivot pin 3 and stub axle pin 4 and the hinged both ends of outer chain sheet 2 are provided with retaining ring 6.
Preferably, rolling assembly, which includes at least one, has non-metallic material using the rigid rollers 7 of metal material and one
The idler wheel 8 of matter outer ring, rigid rollers 7 and idler wheel 8 are multiple rows of parallel setting.In the present embodiment, driving chain uses double knot
Structure, corresponding such structure are arranged with a rigid rollers 7 and an idler wheel 8 respectively on long pivot pin 3 and stub axle pin 4, and the two is coaxially simultaneously
Row's setting, thus rigid rollers 7 are consistent with the quantity of idler wheel 8.Also roller bearing has been added in idler wheel 8 for being set in pivot pin group
On part.
Meanwhile referring to shown in Fig. 6~Fig. 7, three row's structures are can also be used in driving chain, and corresponding rolling assembly may include one
It is a to use metal material using the rigid rollers 7 of metal material and two idler wheels 8 with non-metallic material outer ring, or including two
The rigid rollers 7 of matter and an idler wheel 8 with non-metallic material outer ring.
Two-row structure shown in Figure 3, that this kind of step chains have, in straightway operation, idler wheel 8 rolls on guide rail
And the weight of support chains and step, rigid rollers 7 are detached from guide rail and empty operation, and when the arc of operation turns to section, 8 He of idler wheel
Rigid rollers 7 are engaged with duplex chain wheel 9 by metal guide rail and unloading guide supporting, idler wheel 8 and rigid rollers 7 simultaneously respectively, are held
Carry the summation that power is two single strand chain bearing capacities, this structure have simultaneously the small vibration of built-in wheel step chains, low noise and
The big advantage of the bearing capacity of external wheel step chains.
It is shown in Figure 4, the rolling bearing in idler wheel 8 can be replaced with sliding bearing 10, can also realize that idler wheel 8 is set in
On pivot pin component.
Shown in Figure 5, when driving chain is two-row structure, rolling assembly, which includes two, has non-metallic material outer ring
Idler wheel 8, idler wheel 8 are multiple rows of parallel setting.Or rolling assembly includes multiple rigid rollers 7 using metal material, rigidity is rolled
Son 7 is multiple rows of parallel setting, this kind of structure is similar to the structure of two-row roller, and Gu Tuzhong is no longer shown.
In view of this, the present invention provides compound multiple rows of step driving chain, the multiple rows of structure having, straight
One row's idler wheel or roller roll the weight of simultaneously support chains and step on guide rail when line segment is run, the idler wheel or roller of remaining row
It is detached from guide rail and empties operation, turn to the plurality of rows of idler wheel of section or roller respectively by metal guide rail and unloading guide rail branch in the arc of operation
It supports, for the idler wheel or roller in multiple rows of structure simultaneously with duplex chain wheel engagement, bearing capacity is the single strand chain bearing capacity of corresponding number of rows
Summation, this structure has the bearing capacities for shaking small, low noise and external wheel step chains of built-in wheel step chains big simultaneously
Advantage.Simultaneously as the engagement area of pivot pin and axle sleeve is bigger than single row configuration, wearability is good, meanwhile, pivot pin length is big, axis
A possibility that selling out total detachment chain piece reduction, the safety in operation of escalator operation are higher.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
