Problems solved by technology

[0002] The operation of the steps is driven by the transmission shaft. The two ends of the transmission shaft are driven by chains. When the chains on both sides are not synchronized during the operation of the escalator, the position where the transmission shaft passes through the step shaft hole is easily broken and damaged, causing the steps to fall off. prone to safety accidents

Abstract

The invention discloses a fixing device for a step transmission shaft of an elevator, and relates to the technical field of elevator parts. The device comprises a step on which a transmission shaft isarranged, wherein a shaft hole is formed in the step, and the transmission shaft penetrates the through hole; a guide column is fixedly connected to the step. The device further comprises a connecting plate; the connecting plate is of an integrated or detachable structure and sleeves the guide column and the transmission shaft and is fixed to the step through a bolt; and a lubricating mechanism is arranged between the transmission shaft and the connecting plate. According to the device, the connecting plate is arranged at the outside of the shaft hole in which the transmission shaft is mounted; in case of breaking of the shaft hole, the transmission shaft can be fixed for the second time through the connecting plate; in addition, the lubricating mechanism is arranged between the transmission shaft and the connecting plate, thus the abrasion of the transmission shaft and the connecting plate due to long-time relative rotating can be prevented, and as a result, the effect of the connecting plate in supporting and fixing the transmission shaft is further improved.

Description

technical field [0001] The invention relates to the technical field of elevator components, in particular to an elevator step transmission shaft fixing device. Background technique [0002] The operation of the steps is driven by the transmission shaft. The two ends of the transmission shaft are driven by chains. When the chains on both sides are not synchronized during the operation of the escalator, the position where the transmission shaft passes through the shaft hole of the step is easily broken and damaged, causing the steps to fall off. It is easy to cause safety accidents. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an elevator step transmission shaft fixing device. [0004] The present invention adopts following technical scheme: [0005] A drive shaft fixing device for an elevator step, comprising a step, on which a drive shaft is arranged, and a shaft hole is opened on the step, the drive sh...
