Furthermore, the turning end step overturning anti-falling device also comprises a fixing plate vertically arranged on the side surface of the floor plate supporting channel steel, and the braking safety switch is fixed on the fixing plate; the bottom of the fixing plate is provided with a first through hole, the striking rod is rotatably connected to the bottom of the fixing plate through a bolt and a second nut, and a safe running distance is kept between the tail end of the striking rod and a theoretical running track of the rotary step.
Furthermore, a sleeve is sleeved on the bolt, and the striking rod is sleeved on the sleeve.
Furthermore, the section of the sleeve is in a step shape, the striking rod is attached to the step surface of the sleeve, sleeved at the end with the smaller diameter of the sleeve, and axially limited through the gasket.
Further, the safe running distance is set to 60 mm.
Furthermore, a C-shaped section parallel to the floor plate supporting channel steel is fixed on the side face of the floor plate supporting channel steel, and the opening of the C-shaped section faces outwards; and the upper part of the fixing plate is provided with a second through hole and is connected to the C-shaped section bar in a sliding manner through a diamond screw and a first nut.
The beneficial effects of the utility model reside in that:
the utility model discloses a set up a braking safety switch on the floor board support channel-section steel of gyration end top, braking safety switch's the pole of beating end is close the gyration step. When the rotary step is disengaged and deviates from the original motion track, the rotary step collides with the knock-off rod to trigger the braking safety switch to stop the escalator, so that the step is prevented from colliding with the floor plate and the comb pedal. Therefore, the utility model discloses an anticreep device can improve the factor of safety of gyration end, ensures passenger's safety.

Detailed Description
The turning and anti-falling device for turning end steps according to the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The turning end step anti-drop device shown in fig. 1 and 2 comprises a braking safety switch 3, a beating rod 4 for detecting whether the turning step 1 is disengaged and triggering the braking safety switch 3 to stop the escalator, and a fixing plate 5. The fixed plate 5 is vertically arranged and is arranged on the side surface of the floor plate supporting channel steel 2, and the braking safety switch 3 and the striking rod 4 are both arranged on the fixed plate 5. When the rotary step 1 is separated and deviates from the theoretical running track, the rotary step 1 collides with the knock-off rod 4 to trigger the braking safety switch 3 to stop the escalator, so as to prevent the step from colliding with the floor plate and the comb pedal.
Specifically, referring to fig. 3, a C-shaped profile 6 is fixed on the side surface of the floor plate support channel 2 in parallel with the floor plate support channel, and the opening of the C-shaped profile 6 faces outwards. The upper part of the fixing plate 5 is provided with a second through hole which is connected on the C-shaped section bar 6 in a sliding way through a diamond-shaped screw 7 and a first nut 8 (the head of the diamond-shaped screw 7 is embedded in the C-shaped section bar 6).
The brake safety switch 3 is fixed on the fixing plate 5 by screws. The bottom of the fixed plate 5 is provided with a first through hole, and the striking rod 4 is rotatably connected to the bottom of the fixed plate 5 through a bolt 9 and a second nut 10. Specifically, the bolt 9 is sleeved with a sleeve 11, the section of the sleeve 11 is in a step shape, the striking rod 4 is attached to the step surface of the sleeve 11, sleeved at the end with the smaller diameter of the sleeve 11, and axially limited by a gasket. The safe running distance is kept between the tail end of the striking rod 4 and the theoretical running track of the rotary step 1, and in the embodiment, the safe running distance is set to be 60 mm.
After the step chain is tensioned, the whole step overturning anti-falling device can slide on the C-shaped section 6 and can be adjusted according to the specific set safe running distance, and the theoretical distance between the tail end of the beating rod 4 and the rotary step 1 is kept unchanged.
In this embodiment, the braking safety switch 3 is a normal open switch.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principles of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
