Abstract
The utility model relates to a detection device and especially relates to an anti-deflection detection device of a lift track. The anti-deflection detection device of the lift track comprises a lifting cage and a track, wherein the lifting cage is connected with the track through sliding by a pulley device, a drive plate fixed to the lifting cage is disposed above the lifting cage, a fixation base is disposed on the drive plate, a sensor installation plate is disposed inside the fixation base, the lower end of the fixation base is fixed to the sensor installation plate by adjusting screws, the adjusting screws are distributed with the track in an alternative manner, the upper end of the fixation base is equipped with a normally-open sensor and a normally-close sensor, the normally-open sensor and the normally-close sensor are respectively perpendicular to the track in an alternative manner and the normally-open sensor and the normally-close sensor are respectively connected to an electric-control system controller. The anti-deflection detection device of the lift track is compact in structure and has improved safety, adjustable sensitivity and good detection performance.
Description
Technical field
The utility model relates to a kind of detecting device, relates in particular to the anti-crooked detecting device of a kind of rail of lifter.
Background technology
Rail mounted elevator of the prior art is the general vertical transportation machinery of elevator machinery industry in the world, is well known that the crooked detection of not anti-track and running protection.Therefore there is every year in operation and disassembly process because track loosened screw drops or do not fill and collapse the grave accident generation that the machine people of causing dies.For this reason country former GB T10054-2005 < < building hoist > > revision be the dual-purpose building hoist > of the people's goods > standard that new GB26557-2011 < < cage has vertically-guided; require enterprise to overcome difficulties; invention has the crooked detection defencive function of corresponding track, thereby controls technically the generation of this accident.
Utility model content
The utility model is mainly to solve the deficiencies in the prior art; a kind of compact conformation is provided; when sensor and interorbital distance surpass the error amount of regulation; working sensor state changes at once; output control signal, controls motor out of service, makes cage not enter the track of crooked part; play the effect of safety guard-safeguard, thereby reach technically the anti-crooked detecting device of rail of lifter of obviate safety misadventure object.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of rail of lifter is prevented crooked detecting device, comprise cage and track, described cage passes through pulley gear phase sliding block joint with track, the top of described cage is provided with the driver plate fixing with it, described driver plate is provided with permanent seat, in described permanent seat, be provided with installation of sensors plate, the lower end of described permanent seat and installation of sensors plate fix by governing screw, the interruption-like distribution of described governing screw and track, the upper end of described permanent seat is provided with and often opens sensor and normally closed sensor, it is described that often to open sensor interruption-like vertical with track respectively with normally closed sensor, the described sensor of often opening is connected with electric control system controls device respectively with normally closed sensor.
As preferably; described driver plate and cage are fixedly connected by bearing pin; the outer wall of described sensing adapter plate is provided with the gusset distributing separately with track; in described driver plate, be provided with cable protective tube; the described sensor of often opening is connected with electric control system controls device by sense line respectively with normally closed sensor, described sense line and the cross-under of cable protective tube phase.
As preferably, described gusset, installation of sensors plate and permanent seat fix by check screw respectively, and described governing screw regulates mutually by setting nut.
As preferably, the described top of often opening sensor and normally closed sensor is respectively equipped with protection steel plate, described often opens sensor and normally closed sensor fixes by captive nut respectively.
When track because of install or operation after binding bolt loosening cause crooked to a certain degree time, the anti-crooked detecting device of track being arranged on cage will detect crooked signal, thereby by electric control system controls device, cut off the cage moving, guarantee that cage forbids entering dangerous crooked track, finally guarantee the safe in operation of cage.
Therefore, rail of lifter of the present utility model is prevented crooked detecting device, and compact conformation promotes safety, and sensitivity is adjustable, detects performance good.
