Description

Technical Field

[0001] The utility model belongs to the technical field of escalator equipment, and particularly relates to a handrail detection device. Background Technique

[0002] The future development trend of escalator maintenance is to be refined, professional, and maintenance on demand. For the tension adjustment of the handrail of the escalator, it is the tension that is adjusted. However, front-line personnel can only rely on their senses and experience to adjust its tension. In the practical process, it is found that many handrail wire-out problems are caused by excessive tension. Adjusting the tension too tightly is beneficial to maintenance personnel, reducing the maintenance working hours, and even not needing to adjust the handrail for multiple maintenance cycles. However, there is no clear index for what state the handrail tension is adjusted to, and it is impossible to clarify what is well adjusted and what is not well adjusted. Research is carried out on this, and the optimal tension of the handrail and its adjustment method are obtained.

[0003] In order to obtain the optimal tension of the handrail and its adjustment method, realize the refined and professional maintenance of the handrail, and improve the service life and reliability of the handrail system at the same time, the following handrail tension detection devices are adopted in the prior art:

[0004] a) The application of CN 112707299 A proposes a handrail automatic tensioning wheel device and an escalator with the device built in, including: a controller; a power supply interface and an input interface, the input interface is connected to the controller and is used to transmit real-time data to the controller; a server interface, the server interface is used to monitor the real-time data of the handrail of the escalator; a communication interface, one end of the communication interface is connected to the input interface, and the other end is connected to the server interface, and is used to transmit the real-time data fed back by the server interface to the input interface; a first tensioning motor and a second tensioning motor; a pulse interface includes a first tensioning pulse signal interface and a second tensioning pulse signal interface, and the first tensioning pulse signal interface and the second tensioning pulse signal interface are respectively used to send differential signals to the first tensioning motor and the second tensioning motor; however, this prior art has great drawbacks and cannot monitor the abnormal temperature change during the operation of the handrail;

[0005] b) CN 203682848 U "Passenger Conveyor", including: a plurality of steps that move in a cycle within the main frame; a pair of railings that are vertically arranged on both sides of the steps; a handrail that is arranged on the railings and moves around the railings synchronously with the cyclic movement of the steps; a handrail driving device that drives the handrail; a contact body that presses the handrail downward and imparts tension to the handrail; a force applying part that applies a downward force to the contact body; and a detection part that detects the upward movement of the contact body; however, this prior art is arranged on the steps and moves in a cycle synchronously with the steps, and the installation is complex and the cost is high;

[0006] c) CN 209974083 U, "A New Type of Handrail Belt Tension Adjustment Device": The lower support and the upper support are respectively installed at the upper and lower ends of the truss of the escalator. One end roller of the arc-shaped roller group is fixed to the lower support through a roller fixing component. A deviation prevention wheel is fixed above the roller through a bracket for the middle part of the roller fixing component. The handrail belt is threaded between the roller and the deviation prevention wheel. The other end roller fixing component of the arc-shaped roller group is fixed with an adjusting rod through a connecting piece. The adjusting rod extends vertically upward and passes through the upper support. An elastic member and an adjusting member are sequentially sleeved on the adjusting rod above the upper support.
