Abstract
The utility model discloses a simply-disassembled-and-assembled self-lubricated escalator turning chain, aiming at providing the simply-disassembled-and-assembled self-lubricated escalator turning chain which is simple in structure, easy to manufacture, low in cost, long in service life and convenient to assemble and disassemble. The simply-disassembled-and-assembled self-lubricated escalator turning chain comprises chain plates made of engineering plastics; all the sections of chain plates are connected in series by the heads and the tails; a wheel shaft is inserted into the middle of each chain plate along the transverse direction; the two ends of the wheel shaft are respectively provided with a roller wheel; and a shaft sleeve is arranged between each wheel shaft and each chain plate. The simply-disassembled-and-assembled self-lubricated escalator turning chain is characterized in that the two ends of each chain plate are respectively provided with a large branch fork and a small branch fork, wherein the size of an inner fork of the large branch fork is more than or equal to that of an outer fork of the small branch fork; the two outer sides of the small branch fork are respectively provided with a connecting pin; and the inner side of the large branch fork is provided with connecting holes matched with the connecting pins. The simply-disassembled-and-assembled self-lubricated escalator turning chain has the advantage that the connection of the units of the chain plates can be assembled when the large branch forks and the small branch forks are in a state of elastic deformation, so that linking units can not be damaged when assembly and disassembly are carried out at the normal temperature.
Description
Technical field
The utility model relates to chain, relates in particular to a kind of self-lubricating staircase revolution chain easy to assemble.
Background technology
Prior electric staircase revolution chain is to process a joint joint carrier bar by engineering plastics to be in series shape such as Y shape each other; Both sides at its front end are shaped on lateral pin; Stuck in two minutes of the rear end and be shaped on the connecting bore that matches with lateral pin, be inserted with wheel shaft in the intermediate lateral of carrier bar, the two ends of wheel shaft are equipped with roller.The axle sleeve anti-attrition is installed between wheel shaft and the carrier bar.Such structure needs forked section under thermoplastic state, the connecting bore that bifurcated draws back the both sides, back by force to be enclosed within respectively in the lateral pin of coupled carrier bar when carrier bar and carrier bar are installed, and deformation is recovered in the cooling back, and two carrier bars are in the hinge connection.Such installation extremely bothers, and especially when the maintenance of revolution chain, can forked section be damaged very well, changes difficult to the maintenance in later stage.In use axle sleeve and carrier bar do not have circumferencial direction location in addition, cause axle sleeve through behind the long-play owing to becoming flexible appears in reason axle sleeve external diameter that expands with heat and contract with cold and carrier bar, the wearing and tearing that relatively rotate of axle sleeve and carrier bar cause the axle sleeve premature failure.
The utility model content
The purpose of the utility model be to provide a kind of simple in structure, easy to manufacture, cost is low, long service life, self-lubricating staircase revolution chain easy to assemble easy to loading and unloading.
In order to achieve the above object; The technical scheme of self-lubricating staircase easy to assemble revolution chain is: it includes the carrier bar of processing with engineering plastics, and a joint joint carrier bar head and the tail series connection each other is inserted with wheel shaft in the intermediate lateral of carrier bar; The two ends of wheel shaft are equipped with roller; Between wheel shaft and the carrier bar axle sleeve is installed, it is characterized in that the two ends of said carrier bar are shaped on big bifurcated and little bifurcated respectively, wherein the interior fork size of big bifurcated is more than or equal to the outer fork size of little bifurcated; On two lateral surfaces of little bifurcated, be shaped on connecting pin respectively, be shaped on the connecting bore that matches with connecting pin in the inboard of big bifurcated.
The front end face of said connecting pin is shaped on the chamfering of being convenient to install.
End face at described axle sleeve is shaped on flange, on the external diameter of axle sleeve, is shaped on the positioning bar of outstanding external diameter, is shaped on the positioning groove that matches with positioning bar in the sleeve block hole on the carrier bar matching with axle sleeve.
According to the self-lubricating staircase revolution chain easy to assemble that such scheme is made, its advantage one is that the connection between the carrier bar unit can all can be assembled down by the state at elastic deformation at big bifurcated and little bifurcated, can be implemented in that dismounting can not damage link unit under the normal temperature.To bring convenience in the mounting or dismounting of turning round chain maintenance intermediate plate in the future.When on the axle sleeve external diameter, having added positioning bar, avoided owing between the sleeve block hole of loosening external diameter of axle sleeve and carrier bar the phenomenon that wearing and tearing cause chain to damage ahead of time takes place.

The specific embodiment
Through embodiment the utility model is done further to describe below.
The structural representation of Fig. 1 self-lubricating staircase revolution easy to assemble chain.Find out that from figure it includes 1, the one joint joint carrier bar 1 head and the tail series connection each other of the carrier bar processed with engineering plastics, be inserted with wheel shaft 2 in the intermediate lateral of carrier bar 1, the two ends of wheel shaft 2 are equipped with roller 3, between wheel shaft 2 and the carrier bar 1 axle sleeve 4 are installed.The two ends of said carrier bar 1 are shaped on big bifurcated 5 and little bifurcated 6 respectively; The interior fork size A of wherein big bifurcated 5 is more than or equal to the outer fork size B of little bifurcated 6; On two lateral surfaces of little bifurcated 6, be shaped on connecting pin 7 respectively; The front end face of connecting pin 7 is shaped on the chamfering of being convenient to install 8, is shaped on the connecting bore 9 that matches with connecting pin 7 in the inboard of big bifurcated 5 like Fig. 2, shown in Figure 3.
End face at described axle sleeve 4 is shaped on flange 10, and the positioning bar 11 that on the external diameter of axle sleeve 4, is shaped on outstanding external diameter is like Fig. 4, shown in Figure 5.Be shaped on the positioning groove 13 that matches with positioning bar 11 in the sleeve block hole 12 on the carrier bar 1 matching with axle sleeve 4.Axle sleeve 4 is installed in the sleeve block hole 12 and just can rotated relatively.
