The bracket is provided with a limit switch with the model of Z4V7H 335-11Z-RVA-2622.

When the bracket works, the bracket is in a flat state and is vertical to the guide rail.

When the bracket does not work, the bracket is positioned between the guide rail and the door leg and is positioned in an upward oblique direction, and the upward oblique direction faces the door leg.

The utility model has the following beneficial effects: the electric push rod controls the connecting shaft to turn over, so that the bracket is driven to rotate clockwise or anticlockwise, the operation is time-saving and labor-saving, and the safety of maintenance personnel is protected.

Drawings

Fig. 1 is a schematic structural view of an automatic retraction device applied to an industrial elevator maintenance bracket.

Fig. 2 is a partially enlarged schematic view of fig. 1.

Fig. 3 is a schematic top view of fig. 2.

The device comprises a support frame 1, an electric push rod 2, a bracket 3, a connecting shaft 4, a pull rod 5, a limit switch 6, a protective guard 7, a door leg 8, a car 9, a pit 10 and a guide rail 11.

Detailed Description

An automatic retraction device applied to an industrial elevator maintenance bracket is characterized in that a pit 10 is arranged below a car 9, a plurality of guard rails 7 are arranged on the periphery of the pit 10 to form a protection platform, a door leg 8 is arranged on one side of the car 9, and the car 9 vertically moves up and down on a guide rail 11.

As shown in fig. 2, the bracket 3 is provided between the car 9 and the pit 10, the bracket 3 is positioned at the bottom of the car 9, and the bracket 3 is perpendicular to the guide rail 11 in a flat state when the bracket 3 is operated. When the folding-up device does not work, the bracket 3 rotates clockwise by 90 degrees, the bracket 3 is positioned between the guide rail 11 and the door leg 8 and is in an oblique upward direction, the oblique upward direction faces the door leg 8, and in the folding-up state, the bracket 3 rotates clockwise from the horizontal position to the upward inclined position.

A platform 12 is arranged below the bracket 3, one end of the platform 12 is connected with the guide rail 11, the bottom of the other end of the platform is fixedly connected with a support frame 1, and the other end of the support frame 1 is fixedly connected with the guide rail 11.

As shown in fig. 3, bracket 3 is controlled by connecting rod tilting mechanism and rotates along the axial, connecting rod tilting mechanism includes two connecting axles 4 of parallel arrangement, be connected with pull rod 5 through the otic placode on connecting axle 4, door leg one side is connected with electric putter 2 through the otic placode, the 2 other ends of electric putter pass through otic placode fixed connection on connecting axle 4, pull rod 5 is two, electric putter 2 is located between two pull rods 5, along with electric putter 2's flexible, drive connecting axle 4 anticlockwise or clockwise upset, coaxial connection has bracket 3 on connecting axle 4, along with the rotation of connecting axle 4, it rotates to drive bracket 3.

The bracket 3 is provided with a limit switch 6 with the model of Z4V7H335-11Z-RVA-2622, and the bracket 3 rotates clockwise under the folding state until the limit switch 6 is touched, and the overturning is stopped.
