Problems solved by technology

However, in current use, it is found that if something or a person is stuck between the steps and the comb plate, and the comb plate cannot move flexibly, the electrical safety device cannot be triggered, which may cause greater harm to the human body, or damage the escalator. equipment causing more damage
At present, the installation or maintenance personnel need certain experience and skills to judge whether the comb plate can move flexibly by artificially pedaling the comb plate. The judgment is subjective and affects the accuracy of judgment.

Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as Figures 1 to 4 As shown, a comb-tooth plate force detection device of an escalator is used to detect the squeezing force between the comb-tooth plate 100 and the steps 101 . The comb force detection device of the escalator includes a guide 1 installed on the step 101 , a tension gauge 3 fixedly installed on the guide 1 , and a push frame 2 movably arranged on the guide 1 . The pushing frame 2 is slidably connected with the guide piece 1 . The pushing frame 2 can move left and right under the guidance of the guide piece 1 . In this embodiment, the guide member 1 is a hollow sleeve, and the pushing frame 2 is passed through the sleeve. The lower part of the sleeve is fixedly provided with a clamping plate 4 , which is L-shaped. The clamping plate 4 is clamped at the corner of the step 101 so that the sleeve is detachably insta...

Abstract

The invention discloses a comb plate stress detecting device of an escalator. The comb plate stress detecting device comprises a guide part mounted on a step, a tension meter fixedly arranged on the guide part and a pushing frame movably arranged on the guide part, wherein the pushing frame can move left and right under the guide effect of the guide part; one end of the pushing frame is in contact with the end part of the comb plate; the stress end of the tension meter is fixedly connected with the pushing frame; when the step moves in a direction getting close to the comb plate, the guide part moves in the direction getting close to the comb plate under the driving of the step; under the tension effect of the stress end of the tension meter, the pushing frame abuts against the comb plate; and the tension meter can be used for detecting stress of the comb plate. According to the comb plate stress detecting device, the pushing frame can abut against the comb plate, the guide part can move in the direction getting close to the comb plate along with the step, and the tension meter can accurately detect the size of stress between the comb plate and the step, so that the flexibility of the comb plate can be judged. The detecting device is simple in structure, is convenient in detection, is sensitive in detection, and is high in detected result reliability.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a force detection device for a comb plate of an escalator. Background technique [0002] With the increasing use of escalators, the safety problems encountered by escalators in various use environments have attracted more and more attention. At present, the comb meshing between the steps of escalators or moving walks in shopping malls and supermarkets and the comb plate at the end is relatively tight. If there is something or people stuck between the step and the comb plate, it will cause a squeeze accident. In order to prevent the occurrence of safety accidents caused by the pinching between the comb plate and the steps, a safety electrical trigger switch is currently installed behind the comb plate, that is, when the comb plate is subjected to a certain extrusion force, The comb-tooth plate moves backwards to touch the safety electric trigger switch, and the saf...
