Abstract
The invention discloses a large-height escalator with a heavy-load safety step chain. The large-height escalator comprises the heavy-load safety step chain, and the heavy-load safety step chain comprises a plurality of chain link units which are circularly connected; each chain link unit comprises inner chain plates, outer chain plates and pin shafts, wherein the inner chain plates are configured in a paired manner and are mutually parallel, the outer chain plates are configured in a paired manner and are mutually parallel, and every two adjacent inner chain plates are connected through one outer chain plate and connected with the outer chain plates through the pin shafts; the pin shafts are sleeved with inner rolling wheels which are sleeved with sleeves, the thickness of the outer chain plates is 10mm, and the width of the outer chain plates is 7.5mm; and the lowest tensile limit loads of the heavy-load safety step chain are 520KN. The escalator has the beneficial effects of being high in safety and capable of meeting the requirements and being widely applied to an occasion where the lifting height is below 50 meters.
Description
Technical field
The present invention relates to escalator technical field, particularly a kind of high-altitude escalator with heavy-duty safety type step chain.
Background technology
The step chain of escalator is the driving component of escalator, it is the main transferring power component of staircase, its safety factor of Standard is not less than 5, but in the escalator that hoisting depth is very large, if hoisting depth is 50 meters, its safety factor requires as being not less than 8, to ensure its use safety.The maximum hoisting depth of current escalator is below 20 meters, and minimum ultimate tensile load is 320KN.This is the place that the present invention needs to improve emphatically.
Summary of the invention
Technical matters to be solved by this invention to provide a kind of hoisting depth to reach 50 meters, and safety is high, the high-altitude escalator of what bearing capacity was large have heavy-duty safety type step chain.
In order to solve above technical matters, the invention provides a kind of high-altitude escalator with heavy-duty safety type step chain, comprise heavy-duty step chain bar, described heavy-duty step chain bar 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 pin link plate for two adjacent inner plates are connected parallel to each other, for the bearing pin that inner plate is connected with pin link plate, bearing pin overcoat has internal trolley, internal trolley is loaded in sleeve, the thickness of described pin link plate is 10mm, width is 7.5mm, the minimum ultimate tensile load of described heavy-duty step chain bar is 520KN.
The inner width of described inner plate is 34mm.
The pitch of described pin link plate is 133.33mm.
The high-altitude escalator with heavy-duty safety type step chain of the present invention is the application in the place of less than 50 meters at hoisting depth.
Superior effect of the present invention is:
1) meet the requirement of large highly heavily loaded escalator, the place under hoisting depth 50 meters one-tenth can be widely used in;
2) safety is high, and minimum ultimate tensile load can reach 520KN.
