Abstract
The invention provides a step chain wheel transmission mechanism. The step chain wheel transmission mechanism comprises step chain wheels positioned on the two sides of a step of an escalator, step chain groups positioned on the two sides of the step of the escalator, sleeves and a step main shaft; each step chain group comprises two step chains; the two step chains in each step chain group are connected through a plurality of sleeves; the step chains on the two sides of the step are connected with the step chain wheels through the step main shaft; and the step chain wheels are installed at one end, far away the sleeves and close to the step, of each step chain group, so the installation position of the original step chain wheels is changed. By an installation mode, the friction between the step chain wheels and the step chains is reduced, so the intensity of the step chains is greatly enhanced; moreover, the step chain wheels can be independently replaced, so the time for disassembly, maintenance and repair of the step chain wheel transmission mechanism is saved.

Summary of the invention
The present invention provides a kind of step chain wheel driving mechanism, so that the intensity of step chains strengthens greatly, satisfy the higher ladder type intensity of hoisting depth, and the dismounting maintenance time when having reduced ladder sprocket wheel to a great extent and damaging.
The present invention proposes a kind of step chain wheel driving mechanism; Comprise: be positioned at the ladder sprocket wheel of the step both sides of escalator, the step chains group that is positioned at the step both sides of escalator, sleeve and step main shaft; Each step chains group comprises two step chains; Two step chains in each step chains group connect through some sleeves, and the step chains of step both sides is connected through the step main shaft with ladder sprocket wheel, and said ladder sprocket wheel is installed on the step chains group away from sleeve and near an end of step.
Further, said ladder sprocket wheel is arranged on the guide rail of escalator.
Further, each said step chains comprises some step chains and some chain sheets, and said some chain sheets are arranged at the two ends of each step chain respectively.
Compared with prior art, the present invention has following beneficial effect:
The present invention is through being installed on ladder sprocket wheel the step chains group away from sleeve and near an end of step; Changed the installation site of original ladder sprocket wheel; This installation form has reduced the friction force between ladder sprocket wheel and the step chains, and the intensity of step chains is had very big enhancing (the minimum tension ultimate load of step chains is 260000N); And this installation form also makes ladder sprocket wheel change separately, has practiced thrift the time to this step chain wheel driving mechanism dismounting, maintenance and maintenance.
In addition, the present invention makes ladder sprocket wheel when operation, can support to some extent through said ladder sprocket wheel is arranged on the guide rail of escalator.
In addition, the present invention not only can strengthen the intensity of step chain through at every step chain two ends the chain sheet being set, and also makes the dismounting of step chains more convenient.
