The invention discloses an idler-wheel type guiding device used for an elevator, and belongs to the field of elevators. The idler-wheel type guiding device used for the elevator is composed of idler wheels, a movable idler wheel support, a fixed idler wheel support, a compression spring, screws and nuts. The movable idler wheel support and the fixed idler wheel support are arranged at an interval in parallel, one ends, corresponding to each other, of the movable idler wheel support and the fixed idler wheel support are connected through the screws and nuts in an adjustable mode, and the compression spring is connected between the movable idler wheel support and the fixed idler wheel support. The idler wheels are installed in the movable idler wheel support and the fixed idler wheel support respectively through idler wheel connecting pin shafts, and the fixed idler wheel support is fixedly connected with a rack. The movable idler wheel support is movably connected with the rack of the elevator through a connecting pin shaft of the movable idler wheel support. The pressure of the compression spring between the movable idler wheel support and the fixed idler wheel support is adjusted, so that the movable idler wheel support slides relative to the rack through the connecting pin shaft of the movable idler wheel support, the idler wheels of the movable idler wheel support and the fixed idler wheel support and idler wheel tracks corresponding to the movable idler wheel support and the fixed idler wheel support respectively keep close fitting motion, the elevator can operate more stably and reliably, and the blocking phenomenon or derailing accidents do not occur.
Description
technical field [0001] The invention relates to a roller-type guiding device for an elevator, which belongs to the field of elevators. Background technique [0002] The guide device exists in various lifting platforms, and mainly plays a role in positioning and guiding the lift. The existing elevator guiding device is rigidly connected to the track, and the guiding is realized through the sliding fit between the guide block and the track. Therefore, the straightness, parallelism and smoothness of the track are highly required. If the track is rough and not smooth, the elevator will vibrate greatly during operation, and even accidents such as jamming and derailment may occur. Therefore, it is necessary to develop a guide device with high safety to improve the stability and safety of the elevator. Contents of the invention [0003] The object of the present invention is to provide a roller-type guide device for an elevator, so as to improve the running stability and safety...
