Description

Technical Field

[0001] The utility model relates to the technical field of escalators and moving walkways, in particular to a step shaft sleeve anti-loosening detection device. Background Art

[0002] With the rapid development of social economy and the continuous improvement of people's living standards, escalators or moving walkways have become an indispensable part of people's daily life, and are appearing more and more in people's daily life scenes. They are widely used in public places such as shopping malls and public transportation. During the use of escalators or moving walkways, due to the complex structure, there are gaps in some positions that cause foreign objects to get stuck, or mechanical failures cause the steps of the escalator to be misaligned or sink. Problems such as these seriously affect safety. The step sinking detection device in the prior art often requires the steps to be destructive before it is triggered. It is not easy to detect when the steps are loose, and the detection accuracy is not high, which can easily cause safety accidents. Utility Model Content

[0003] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a step sleeve anti-loosening detection device, including a mounting plate, a plurality of plate fixing holes are arranged on the mounting plate, shaft mounting holes are symmetrically arranged on both sides of the mounting plate, a rotating shaft is arranged in the shaft mounting hole, rod mounting holes are symmetrically arranged at both ends of the rotating shaft, trigger rods are fixedly connected in the rod mounting holes, and a trigger structure is arranged on any side of the mounting plate.

[0004] Through the above technical scheme, when installing the step sleeve anti-loosening detection device, the installation plate is fixed to the truss cross bar by using bolts to pass through the fixing holes of the plate body to complete the installation of the step sleeve anti-loosening detection device. When the step fixed sleeve becomes loose due to the fixing bolts, the fixed sleeve will move along the step shaft toward the direction of the middle trigger rod. After the fixed sleeve moves a certain distance and reaches the position of the trigger rod, the fixed sleeve will move the trigger rod as the step moves, so that the trigger rod drives the rotating shaft to rotate, thereby operating the trigger structure. In addition, the position of the rod body mounting hole, the shape and length of the trigger rod can be set differently according to the actual specifications and conditions of the escalator step sleeve, so as to ensure that the step sleeve anti-loosening detection device can be stably triggered.

[0005] The utility model is further configured that a plurality of switch fixing holes are arranged on a side of the mounting plate close to the trigger structure, and a plurality of brush fixing holes are arranged on a side of the mounting plate away from the switch fixing holes.

[0006] The utility model is further configured that positioning holes are symmetrically arranged at the position of the rotating shaft located on the inner side of the mounting plate.

[0007] Through the above technical solution, a stop rod or a bolt can be set in the positioning hole to limit the rotating shaft and prevent it from moving laterally, thereby ensuring that the trigger rods on both sides can be stably triggered by the loosened step fixing sleeve.

[0008] The utility model is further configured that a destaticizing brush is arranged at a position of the mounting plate near the brush fixing hole, and the destaticizing brush is fixedly connected to the mounting plate by passing bolts through the brush fixing hole.

[0009] The utility model is further configured such that the trigger structure includes a limit switch, the limit switch is fixedly connected to the mounting plate by using bolts to pass through the switch fixing hole, and a switch paddle is provided at the trigger end of the limit switch, and the switch paddle is fixedly connected to the rotating shaft.

[0010] Through the above technical scheme, when the rotating shaft rotates under the action of the trigger rod, it will drive the switch paddle to rotate together, so that the switch paddle triggers the limit switch when rotating, thereby stopping the escalator and shutting down the escalator in time before a safety hazard occurs, thereby ensuring the personal safety of passengers. In addition, the switch paddle and the limit switch are used as trigger structures, which is only a way to stop the escalator under the action of the rotating shaft. According to actual conditions and needs, trigger methods such as distance sensing switches, laser sensors, and visual sensors that can also trigger and stop the escalator under the action of the rotating shaft can be selected.

[0011] The beneficial effects of the utility model are as follows:

[0012] The step shaft sleeve anti-loosening detection device proposed by the utility model has a simple structure and is easy to install and can be directly installed on the truss cross bar. When the step fixing shaft sleeve is loosened by the fixing bolt, the fixing shaft sleeve will move along the step shaft toward the direction of the middle trigger rod. After the fixing shaft sleeve moves a certain distance and reaches the position of the trigger rod, the fixing shaft sleeve will toggle the trigger rod as the step moves, so that the trigger rod drives the rotating shaft to rotate, thereby operating the trigger structure and causing the switch paddle to trigger the limit switch when rotating, thereby stopping the escalator and timely shutting down the escalator before a safety hazard occurs, thereby ensuring the personal safety of passengers.
