Multifunctional elevator auxiliary rescue device

Abstract

The invention discloses a multifunctional elevator auxiliary rescue device. The multifunctional elevator auxiliary rescue device comprises a lift car, rails are arranged on the left side and the right side of the lift car, a first sliding groove is formed in the sides, facing the lift car, of the rails, sliding rods are arranged on the lift car, first rolling wheels are installed at the outer ends of the sliding rods through wheel carriers, a first piston cylinder is arranged in the middle of the lift car and provided with first an air inlet, second piston cylinders are arranged on the left side and the right side of the first piston cylinder, movable rods are arranged in the second piston cylinders, connecting blocks are arranged at the outer ends of the movable rods, second rolling wheels are installed on one sides of the connecting blocks through elastic movable structures, movable blocks are arranged below the first piston cylinder, air leakage control devices are arranged between the movable blocks and the second piston cylinders, and a first one-way valve is arranged in the first air inlet. According to the multifunctional elevator auxiliary rescue device, under the action of gravitational acceleration in the elevator falling process, the first rolling wheels move along the wavy structure of the first sliding groove, so that the speed of external air entering the first piston cylinder is increased, pressure perpendicular to the first sliding groove is applied to the second rolling wheels, and therefore full-mechanical passive braking is achieved, and rescue of people in the interior of an elevator is achieved.

Description

technical field [0001] The invention belongs to the field of elevator assistance devices, in particular to a multifunctional elevator auxiliary rescue device. Background technique [0002] With the development and progress of the current society, there are more and more high-rise buildings, and elevators are the hardware facilities that must be equipped with high-rise buildings. Incident, the existing elevators seldom have auxiliary rescue facilities during the falling process, especially during the falling process of the elevator, there may be a phenomenon that the electronic equipment in the elevator cannot be used and the internal power of the elevator cannot be supplied, thus being trapped People inside the elevator can only wait for the rescue of outsiders, which is prone to safety accidents. Contents of the invention [0003] The invention provides a multifunctional elevator auxiliary rescue device to solve the defects in the prior art. [0004] The present inventi...
