Wherein, bolt detection module 4 adopts magnetic leakage detector, infrared ray detector or ultrasonic detector.
The ground PLC controller 7 is also connected with an acousto-optic alarm module 2 and a touch screen 3; the sound and light alarm module 2 adopts an alarm three-color lamp and an alarm loudspeaker.
And the variable-frequency driving module 6 adopts a variable-frequency driving motor. Preferably, the output end of the variable frequency driving motor is provided with a driving gear, the standard knot frame 300 is fixed with a standard knot rack 500 corresponding to the driving gear, the standard knot racks are spliced to form a whole running rack, the suspension cage 100 is also provided with a guide wheel, the standard knot frame 300 is also fixed with a guide rail corresponding to the guide wheel, and the suspension cage is driven by the variable frequency driving motor to run up and down. It will be appreciated that other lift drive configurations for cage 100 may be used. Of course, the tail end of the variable frequency driving motor is also provided with an encoder for detecting the rotating speed of the variable frequency driving motor, the encoder is in signal connection with the cage PLC controller 1, and the cage PLC controller 1 can convert the rotating speed of the variable frequency driving motor into the operating speed of the cage 100.

A method for detecting the bolt connection reliability of a guide rail frame of an elevator specifically comprises the following steps:
s1, controlling the left and right suspension cages 100 to park in place at the lower limit positions through the ground command button 9;
s2, pressing a detection start button of the ground command button 9 for a long time, sending a start signal to the ground PLC controller 7 by the start button, sending the start signal to the cage PLC controller 1 by the ground PLC controller 7 through wireless communication between the second wireless module 8 and the first wireless module 5, starting the bolt detection module 4 for detecting the guide rail frame bolt 400 by the cage PLC controller 1, and starting the variable frequency driving module 6 inside the cage 100 by the cage PLC controller 1;
s3, the two cages 100 start to ascend synchronously at low speed under the drive of the variable-frequency drive module 6;
s4, during the period when two cages 100 are moving upward, cage PLC controller 1 calculates a travel distance S, S = ═ v · Δ t, where v is the instantaneous speed of cage 100, and Δ t is the time that cage 100 is moving;
s5, the bolt detection module 4 starts to detect the guide rail frame bolts 400 distributed on the guide rail frame, the detected continuous metal length is L, L is the actual length of the guide rail frame bolts 400, h is the initial length of the guide rail frame bolts 400, and i is the length of the standard knot frame 300; if L is more than h, resetting the running distance S; if the accumulated running distance S of the cage 100 is more than i and L is less than h, the cage PLC 1 controls the variable frequency driving module 6 to stop working, the cage 100 stops working, the fault position of the guide rail frame bolt 400 is recorded, and meanwhile, an audible and visual alarm is output through the audible and visual alarm module 2; in this example, h is 245mm and i is 1508 mm. In the actual detection process, the bolt detection module 4 also detects the length information of the standard knot frame 300, and since the length of the standard knot frame 300 is much longer than the actual length of the guide rail frame bolt 400, the cage PLC controller 1 deletes the detected length information of the standard knot frame 300.
S6, if the guide rail bracket bolt 400 is not detected to be out of order during the operation of the suspension cage 100, the acousto-optic alarm module 2 is triggered until the suspension cage 100 operates to the upper limit position, the detection of the guide rail bracket bolt 400 is completed, and the suspension cage 100 returns to the lower limit position, which indicates that no guide rail bracket bolt with the failure exists on the whole guide rail bracket.
Two cage synchronous start on left and right sides begin to detect, and the contralateral bolt that avoids probably appearing in single cage testing process drops, and the cage continues to go upward and leads to the condition that the cage crashed.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
