Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the elevator maintenance safety protection device shown in the figure comprises a car 1, wherein a mounting seat 2 is fixedly mounted at the top of the car 1, and a safety protection assembly 3 capable of being clamped with the top wall and the side wall of an elevator shaft to reserve an escape space for a maintenance worker is fixedly mounted on the mounting seat 2.

Wherein, safety protection subassembly 3 includes speed reducer and support piece, the speed reducer includes movable rod 4, the top of 2 inside setups of mount pad is installed in the embedding of movable rod 4 is established to open structure's cavity in, the one end that movable rod 4 is close to the elevartor shaft lateral wall is provided with integrated into one piece's end 5, the other end fixed mounting of movable rod 4 has powerful spring 6, powerful spring 6's the other end and 2 fixed connection of mount pad, the top of movable rod 4 and cavity is provided with the jack that corresponds each other, the inside demountable installation of jack has the cutting 7 that is used for fixed movable rod 4, when the upward movement that the short circuit can't stop takes place for car 1, end 5 and elevartor shaft lateral wall looks mutual friction slow down the speed of car 1 upward movement through frictional force, and is safer.

In addition, the side wall of the end head 5 is provided with a plurality of insections 8, so that friction force can be increased, and the deceleration effect is better.

Wherein, mount pad 2 is provided with four, every the equal fixed mounting in one side that mount pad 2 is close to the elevartor shaft lateral wall has axle bed 9, support piece includes two pivot 10, every the both ends embedding of pivot 10 is installed inside two adjacent axle beds 9, just the outer tip screw thread of pivot 10 has cup jointed nut 11, every all rotate in the pivot 10 and install telescopic link 12, every all fixed mounting has to hang and detains 13 on the lateral wall of telescopic link 12, and is adjacent demountable installation has the connecting rod 14 that is used for fixed telescopic link 12 between the telescopic link 12 in the pivot 10, when car 1 takes place the unable upward movement that stops of short circuit, telescopic link 12 can with elevartor shaft roof joint to reserve an escape space for the maintainer, realize the purpose to the safety protection when the maintainer overhauls.
