Abstract

The invention provides an elevator stroke switch and a hoistway switch module. The elevator stroke switch comprises a housing, a fixing contact module fixedly arranged on the housing, a wire holder fixed to one end outside the housing, a twist rod fixed to the housing, a twist wheel shaft connected to one end of the twist rod, and a twist wheel in connection with the other end of the twist rod and arranged on the twist wheel shaft; a twist shaft is fixedly provided with a fixing base, in which a torsional spring is arranged and sleeves the twist shaft; the fixing base is also fixedly provided with a movable contact module. The fixing contact module comprises a static contact; the movable contact module comprises two movable contacts which are symmetrically distributed on a same side of the static contact, and are located on an opposite surface of an upper surface of the housing, wherein the static contact is fixed to the upper surface of the housing; one end of the twist rod on the housing is also provided with a position control device. The elevator stroke switch and hoistway switch module improve and simplify a connection relation between contact modules, shorten the size of an elevator stroke switch, have a clever whole design of the position control device, and realize good position-restricted effect.

Description

technical field [0001] The invention belongs to the technical field of elevators and shafts, and relates to a travel switch for elevators, in particular to a shaft switch assembly. Background technique [0002] There is a terminal switch arranged in the stairwell to protect the lift of the car from exceeding the allowable horizontal range. There is a terminal switch installed in the elevator shaft, and the shaft limit switch in the elevator is mainly used for the control and signal prompt of the elevator car's arrival position during the operation of the elevator, and sends the detected signal to the elevator operation controller. The signal provided by the limit control switch judges the running state of the car and performs speed control, so as to ensure that when the car runs to the bottom pit of the hoistway or reaches the top of the hoistway, it is buffered before changing the running direction, so that the elevator car will not There is a danger of squatting or jumpin...
