Problems solved by technology

[0002] Escalators or moving walks are equipped with handrail speed measuring devices to monitor the running speed of the handrails. In the prior art, the handrail speed measuring devices will be interfered by the slack of the handrails to monitor the elevator by mistake. At the same time, the installation environment and use conditions are getting worse. There is a danger of broken handrails, affecting the use of escalators or moving walks and the safety of passengers, reducing product quality

Abstract

The invention discloses a hand strap protection device which comprises a hand strap, a rolling wheel for tensioning the hand strap, a metal component arranged on the rolling wheel, a support installed on the rolling wheel and a probe which is arranged on the support and can detect the metal component. The rolling wheel can be connected to the support in the manner that the rolling wheel rotates in the axial direction of the rolling wheel. The support is connected to an escalator component in a vertical moving manner through guide rods, and elastic parts are connected between the guide rods and the escalator component. The escalator component is further provided with a round check block, and the round check block is provided with a groove. The escalator component is further fixedly provided with a safety switch, and a contact of the safety switch is contained in the groove. Connecting pieces capable of pulling the round check block to rotate are connected between the round check block and the guide rods. After the round check block rotates, the groove ejects the contact of the safety switch to trigger the safety switch. The hand strap protection device has the various functions of automatic hand strap tensioning, hand strap loosening interference resistance, hand strap excessive loosening protection, hand strap breakage protection and the like, and is safe, reliable and convenient to install.

Description

technical field [0001] The invention relates to a handrail protection device, in particular to a handrail protection device which can automatically tension the handrail and can detect whether the handrail is loose or broken. Background technique [0002] Escalators or moving walks are equipped with handrail speed measuring devices to monitor the running speed of the handrails. In the prior art, the handrail speed measuring devices will be interfered by the slack of the handrails to monitor the elevator by mistake. At the same time, the installation environment and use conditions are getting worse. There is a danger of breaking the handrail, which affects the use of escalators or moving walks and the safety of passengers, reducing product quality. Contents of the invention [0003] In view of this, the object of the present invention is to provide a protective device for handrails. In addition to the original function of detecting the running speed of the handrails, automat...
