Gate for factory

Abstract

The invention relates to a gate for a factory, which is connected with the slide rail of the gate. The gate for a factory comprises a door body, a plurality of travelling rollers, a supporting plate, a supporting plate roller, a drive motor and a transmission chain, wherein the supporting plate roller and the travelling rollers are rotationally arranged at the lower end of the middle of the supporting plate and the lower end of the door body respectively, and are in rolling connection with the slide rail; one side end of the supporting plate is in traction connection with the door body, and the side end is a traction end; the drive motor is fixedly arranged on the part of the supporting plate at the other side opposite to the traction end; and the output shaft of the drive motor is in transmission connection with the supporting plate roller via the transmission chain. The motor and the counter weight of the gate for a factory disclosed by the invention take the supporting plate roller as a fulcrum; the friction resistance of the travelling rollers is reduced by virtue of lever principle; simultaneously, a rolling friction force between the supporting plate roller and the slide rail is increased, so that the power of the motor can be properly reduced and the slip of the supporting plate roller can be avoided.

Description

technical field [0001] The invention relates to a factory gate. Background technique [0002] Existing gates usually adopt folding telescopic type or overall translational type, all of which are driven by motors and corresponding driving mechanisms. For slightly larger doors, motors with higher power are required, and in the event of a power failure, the gates are almost paralyzed. , causing great inconvenience to the entry and exit of personnel and the production process, so there is a need for a factory gate that can still be opened and closed in the event of a power failure. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and to provide a factory gate that can still be opened and closed under the condition of power failure, which is specifically realized by the following technical solutions. [0004] A factory gate, connected with the slide rail of the gate, the factory gate includes a door body, several traveling...
