[0002] At present, the application of escalators is becoming more and more extensive. With the vigorous development of public transportation, more and more escalators with large loads are used in the field of public transportation, which requires higher and higher requirements for the step chain. Because the step chain is the part that drives the steps, the main wheel on the chain carries a considerable passenger load. When the steps run to the upper arc of the escalator, the positive pressure on the main wheel is the largest, and the main wheel with excessive force very easily damaged

Embodiment Construction
[0018] A new type of unloading rail structure is designed to be used on public transport escalators with large loads.
[0019] like Figure 1~3 As shown, it is used for the unloading rail structure on the heavy-duty escalator. The unloading rail structure includes the unloading guide rail 1, the shock absorbing pad 2 arranged under the unloading guide rail 1, the supporting rail 3 arranged under the shock absorbing pad 2, and the supporting rail 3 The side plates 4 on both sides, the connecting block 5 arranged under the side plate 4, the head plate 6 arranged at the end of the side plate 4, the unloading guide rail 1, the shock pad 2, the support rail 3, the side plate 4, The connecting block 5 and the head plate 6 form an integral frame type unloading rail structure. The unloading rail structure is set at the upper arc of the escalator, interspersed on the escalator guide rail support plate 20 and arranged parallel to the upper arc main rail 31. There is a gap on the guide ...

The invention provides an unloading rail structure on a heavy-load escalator, which comprises unloading guide rails, a cushion, a support rail, side plates, a connection block and a head plate which form the integral-frame type unloading rail structure, wherein the cushion is arranged below the unloading guide rails; the support rail is arranged below the cushion; the side plates are arranged on both sides of the support rails; the connection block is arranged below the side plates; the head plate is arranged on the end part of the side plates; the unloading rail structure is arranged at the position of an upper arc of the escalator, arranged on the guide rail bracing plate in an interpenetration way and parallel to an upper arched main rail; a step main wheel is arranged above the upper arched main rail and fixed on a step main shaft; and the end part of the step main shaft is provided with a roller. By utilizing the arrangement of the unloading rail structure, when the step reaches the position of the upper arc, the roller on the step main shaft firstly contact the unloading guide rail, so that the step main wheel is suspended above the upper arched main rail, and the positive pressure applied on the step main wheel is greatly reduced, thereby prolonging the service life.
Description
technical field [0001] The invention relates to a novel unloading rail structure used on a heavy-duty escalator. Background technique [0002] At present, the application of escalators is more and more extensive. With the vigorous development of public transportation, there are more and more escalators with large loads in the field of public transportation, which requires higher and higher requirements for the step chain. Because the step chain is the part that drives the steps, the main wheel on the chain carries a considerable passenger load. When the steps run to the upper arc of the escalator, the positive pressure on the main wheel is the largest, and the main wheel with excessive force Very easy to damage. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a new type of unloading rail structure for heavy-duty escalators, which can reduce the pressure on the main wheel of the steps and ...
