Abstract
The utility model discloses an escalator, which comprises a step group, a step chain used for drawing the step group, and a drawing chain wheel meshed with the step chain, wherein the step chain is a roller chain or a roller chain having a N-row structure, N-row teeth are arranged on the drawing chain wheel, and N is larger than or equal to two. By the adoption of the structure, the N-row step chain structure can provide larger breaking strength on the premise that the distance between adjacent chain units is not increased, so that the escalator is suitable for occasions with higher lifting heights or bearing requirements, such as subway, railway stations and the like; and the distance between the adjacent chain units is smaller, so that the escalator has the characteristics of stability in operation and low noise, and can effectively lower the pin shaft specific pressure.
Description
Technical field
The utility model belongs to technical field of elevator manufacturing, is specifically related to a kind of escalator of improveing the step hitch structure.
Background technology
Escalator and moving sidewalk have been widely used in the bigger occasion of the stream of peoples such as subway, market and supermarket at present, because some clients' specific (special) requirements at present needs staircase should possess characteristics such as hoisting depth is very big and stable, noise is low.But the structure that in the prior art, is used to draw the step chains of escalator step group mainly is 3 kinds of single row configuration shown in Fig. 1～3.When this single step chains was applied on the staircase that hoisting depth is very big or span is very big, the tractive force that bear can be very big, and therefore the rupture strength of this single step chains also certainly will increase.In order to guarantee rupture strength and then can to cause the problems such as size increasing, the increasing of roller specification of step chains inner plate and pin link plate, but the step of staircase is apart from generally remaining unchanged, the unit step reduces apart from interior carrier bar joint number like this, cause chain pitch to increase, make that the polygon effect of step chain and sprocket is obvious, the comfort of taking reduces, noise increases.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of simple in structure, hoisting depth or the bigger escalator of span are provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of escalator, comprise the step group, be used to draw the step group step chains and with step chains ingear driving chain sprocket; Described step chains has the N toothrow, wherein N 〉=2 for the roller chain or the roller chain of tool N row structure on the described driving chain sprocket.
As preferably, described step chains is duplex chain or double roller chain.
Further, each step of corresponding step group, described step chains is provided with an axle sleeve and cooperates with the main axle of this step.
The utility model is by adopting said structure, its N row step chains structure can provide bigger rupture strength under the prerequisite that does not increase chain pitch, make the utility model be applicable to that hoisting depth is higher or on the bigger occasion of load bearing requirements, for example subway, Railway station etc.; N row step chain is apart from less, have stable, characteristics such as noise is low, and can effectively reduce the bearing pin specific pressure.

Among the figure:

The specific embodiment
As Fig. 1 to shown in Figure 6, the described escalator of present embodiment, comprise the step group, be used to draw the step group step chains 1 and with step chains ingear driving chain sprocket 2, this step chains 1 is a duplex chain, has double rows of teeth on the described driving chain sprocket 2.This duplex chain is mainly made up side by side by two exclusive carrier bars 11 and inner plate 12, links by single bearing pin 13 to combine, and is meshed with double rows of teeth on the driving chain sprocket 2 by two row rollers 14; And each step 3 of corresponding step group, this duplex chain is provided with an axle sleeve 16 and cooperates with the main axle 32 of this step 1.
When the utility model normally moved, driving chain sprocket rotated and drives the duplex chain motion under the driving of staircase actuating device, and duplex chain traction step 1 makes its main wheel 31 roll along guide rail 4.Because the interior pin link plate of step chains is subjected to loading simultaneously, load is evenly distributed on the interior pin link plate, therefore the suffered power of pin link plate little than single chain structure in duplex chain structure single, and then the increasing degree of pin link plate chain pitch in when increasing the step chains rupture strength, reducing.Again since the sleeve length of duplex chain structure greater than the sleeve length of single chain structure, therefore also little than single chain structure of the bearing pin specific pressure of duplex chain structure under the prerequisite of same load.
As shown in Figure 6, the speed of step chains 1 horizontal direction
When step chains and driving chain sprocket 2 engagements,
This moment the step chains horizontal direction the speed maximum, for
When the step chains five equilibrium is positioned at the centre of sprocket both sides,
This moment the step chains horizontal direction the speed minimum
Therefore the speed of the horizontal direction of step chains is not even variation, becomes periodically alternate, and then causes the vibration of horizontal direction.The speed of step chains vertical direction
Also do cyclical variation, thereby step chains is shaken up and down.The horizontal direction nonuniformity coefficient
Guaranteeing that duplex chain has reduced chain pitch P, has reduced the nonuniformity coefficient of horizontal direction and vertical direction under the driving chain sprocket diameter D unmodified prerequisite.
As shown in Figure 7, the described escalator of present embodiment, its step chains 1 is double roller chain.This double roller chain is mainly made up side by side by two exclusive carrier bars 11 and inner plate 12, links by single bearing pin 13 to combine, and is meshed with double rows of teeth on the driving chain sprocket by two row's rollers 15; And each step of corresponding step group, this double roller chain is provided with an axle sleeve 16 and cooperates with the main axle 32 of this step.
The beneficial effects of the utility model do not repeat them here with embodiment 1.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model and modification are not broken away from principle of the present utility model and purposes, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
