Cross door access machine

Abstract

The invention discloses a cross door access machine, comprising a door leaf, a main shaft, a brake, a sensor kit and a bracket; the brake is installed at the lower end of the central part of the door leaf; the sensor kit is installed below the brake; and the bracket supports the cross door access machine by means of the combination with the ground through screw nails. The cross door access machine has the following advantages that: the brake is installed at the upper part of the door access machine with short main shaft and small torque, and the main shaft is not easy to deform and damage, thereby simultaneously preventing damage of water and dust, prolonging the service life of the machine and facilitating maintenance; the machine has simple structure, convenient installation and low cost, and an emergency device provides better guarantee for use convenience.

Description

technical field [0001] The invention relates to a cross access control device, in particular to a cross access control device which is easy to install. Background technique [0002] figure 1 A schematic plan view of a cross access control machine in the prior art. Such as figure 1 As shown, the cross access control machine includes a plurality of door leaves, a main shaft, a brake, a sensor package and a bracket. Among them, the brake is composed of a rotor and a stator, and the sensor kit is composed of a magnet and a sensor, which are composed of rotatable and non-rotatable parts; A is the ground plane, the brake B is set below the ground, and the door leaf C is connected with the main shaft D through a door pin, and the main shaft D and the rotor under the ground are fixed by screws, and connected with magnets to form a rotatable part with the main shaft as the axis; the stator, sensor and support under the ground are connected to form a non-rotatable part, which is fi...

AI Technical Summary

Problems solved by technology

The cross access control machine with this structure has the following disadvantages: the brake is set under the ground, and the volume is large, so the ground modification is also relatively large and the requirements are high, and it is not easy to fix and install, which increases the installation cost

The door leaf is generally 0.8m above the ground, and is connected with the underground rotor by the main shaft, so the main shaft is very long. When the brake is locked, a person pushing the door leaf will generate a large torque on the main shaft, and the main shaft is easily deformed and damaged.

The relative positions of the four door leaves are fixed and cannot be changed, and can only be rotated at the same time, which is not conducive to the passage of personnel in emergency situations

Cross access control machine has many parts, higher manufacturing cost, difficult to assemble and debug

The brakes are set underground, the brakes are vulnerable to water and dust, and maintenance and maintenance are difficult
