Abstract
The utility model discloses a kind of internal trolley formula step chains, including chain and D type axis pins；The chain is sequentially connected by multiple chain links and formed, and each chain link includes inner plate and roller；There are two the inner plates, parallel and interval setting, and is respectively equipped with roller on the inside of both ends；The both sides of the abutting end of the adjacent link are respectively equipped with outer plate, and one end of the connection of adjacent link passes through corresponding inner plate, outer plate and roller by axis pin, the other end, through corresponding inner plate, outer plate and roller, realizes the connection of adjacent link by D types axis pin；The D types axis pin, which is located on the inside of chain, is equipped with idler wheel；Idler wheel is mounted in the inside of chain by internal trolley formula step chains described in the utility model, and the structure for making entire staircase is compacter, reduces power suffered in the cost and both sides chain of timbering material, improves the service life of chain.
Description
Technical field
The utility model is related to the step chains on heavy-load type escalator, specifically refer in particular to a kind of step chains of internal trolley formula.
Background technology
With the extensive use of escalator, the exploitation of heavy-load type escalator is also increasing, therefore each escalator
Competition between manufacturing firm is also growing more intense；And the price and service life of staircase play very prominent work in competition
With.
At present, the structure of the heavy-load type step chain of automatic escalator of all multi-vendor designs uses idler wheel on the outside of chain
Mode, this structure type not only broaden the distance between rolling wheel guide rails, at the same the power that operationally chain is born also compared with
Greatly.
Utility model content
The utility model aim is to provide a kind of internal trolley formula step chains for overcome the deficiencies in the prior art.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of internal trolley formula step chains, including chain
With D type axis pins；The chain is sequentially connected by multiple chain links and formed, and each chain link includes inner plate and roller；The inner plate
There are two, parallel and interval setting, and it is respectively equipped with roller on the inside of both ends；The both sides of the abutting end of the adjacent link are set respectively
There is outer plate, and one end of the connection of adjacent link passes through corresponding inner plate, outer plate and roller by axis pin, the other end is by D
Type axis pin passes through corresponding inner plate, outer plate and roller, realizes the connection of adjacent link；The D types axis pin is located in chain
Side is equipped with idler wheel；Two axis pins are spaced between the adjacent D types axis pin.
Preferably, described axis pin one end is fixed for die, and the other end is fixed for baffle ring.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Idler wheel is mounted in the inside of chain by internal trolley formula step chains described in the utility model, shortens both sides rolling wheel guide rails
The distance between, the structure for making entire staircase is compacter, reduces power suffered in the cost and both sides chain of timbering material,
The wearing- in period of chain is extended simultaneously, so as to improve the service life of chain.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is the first angle view of internal trolley formula step chains described in the utility model.
Attached drawing 2 is the second angle view of internal trolley formula step chains described in the utility model.
Wherein：1st, inner plate；2nd, outer plate；3rd, axis pin；4th, die；5th, baffle ring；6th, roller；7th, D types axis pin；8th, idler wheel.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Attached drawing 1-2 is internal trolley formula step chains described in the utility model, including chain and D types axis pin 7；The chain by
Multiple chain links are sequentially connected composition, and each chain link includes inner plate 1 and roller 6；There are two the inner plates 1, parallel and interval
It sets, and roller 6 is respectively equipped on the inside of both ends；The both sides of the abutting end of the adjacent link are respectively equipped with outer plate 2, and adjacent
By axis pin 3 through corresponding inner plate 1, outer plate 2 and roller 6, the other end is passed through by D types axis pin 7 for one end of the connection of chain link
Corresponding inner plate 1, outer plate 2 and roller 6, realize the connection of adjacent link；The D types axis pin 7, which is located on the inside of chain, to be equipped with
Idler wheel 8；Two axis pins 3 are spaced between the adjacent D types axis pin 7；Described 3 one end of axis pin is fixed for die 4, and the other end is baffle ring
5 fix.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Idler wheel is mounted in the inside of chain by internal trolley formula step chains described in the utility model, shortens both sides rolling wheel guide rails
The distance between, the structure for making entire staircase is compacter, reduces power suffered in the cost and both sides chain of timbering material,
The wearing- in period of chain is extended simultaneously, so as to improve the service life of chain.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
