Abstract
The utility model discloses a high altitude (HA) staircase is with heavily loaded safe type step chain strip, heavy load step chain strip includes mutual circulating connection's a plurality of chain link unit, and every chain unit is including configuration in pairs and parallel inner plate mutually, in pairs configuration and the parallel outer chain plate that connects double -phase adjacent inner plate of being used for mutually for with the round pin axle of inner plate and outer chain plate connection, round pin off -axial cover has interior gyro wheel, and interior gyro wheel is adorned in the sleeve, outer chain plate's thickness is 10mm, and the width is 7.5mm, the minimum tensile ultimate load of heavy load step chain strip is 520KN. The utility model has the advantages that the security is high, satisfies high altitude (HA) heavy load automatic escalator's requirement, can the place of wide application under lifting height 50 rice becomes.
Description
Technical field
The utility model relates to escalator technical field, particularly one large height staircase heavy-duty safety type step chain.
Background technique
The step chain of escalator is the driving component of escalator, it is the main transferring power component of staircase, its safety coefficient of Standard is not less than 5, but in the escalator that lifting height is very large, if lifting height is 50 meters, its safety coefficient requires as being not less than 8, to ensure its use safety.The maximum lifting height of current escalator is below 20 meters, and minimum ultimate tensile load is 320KN.This is the place that the utility model needs to improve emphatically.
Model utility content
Technical problem to be solved in the utility model to provide a kind of lifting height to reach 50 meters, and Security is high, the large height staircase heavy-duty safety type step chain that bearing capacity is large.
In order to solve above technical problem, the utility model provides a kind of large height staircase heavy-duty safety type step chain, described heavy-duty safety type step chain comprises several link units that mutual circulation connects, each chain unit comprises configuration in pairs and inner plate parallel to each other, paired configuration and the outer plate for two adjacent inner plates are connected parallel to each other, for the bearing pin that inner plate is connected with outer plate, bearing pin overcoat has internal trolley, internal trolley is loaded in sleeve, the thickness of described outer plate is 10mm, width is 7.5mm, the minimum ultimate tensile load of described heavy-duty safety type step chain is 520KN.
The inner width of described inner plate is 34mm.
The pitch of described outer plate is 133.33mm.
Large height staircase heavy-duty safety type step chain of the present utility model is the application in the escalator of less than 50 meters in lifting height.
Superior effect of the present utility model is:
1) meet the requirement of large highly heavily loaded escalator, the place under lifting height 50 meters one-tenth can be widely used in;
2) Security is high, and minimum ultimate tensile load can reach 520KN.
