Problems solved by technology
In the existing domestic indoor elevators, the overload is mostly monitored by the load cell. Using this method, the sensor is in a repeatedly changing pressure environment for a long time, which is prone to errors and instability; moreover, it is also necessary to install a load cell on the car. The installation structure of the heavy sensor makes the structure of the car complicated

The invention relates to the field of household indoor elevators, in particular to an overload monitoring mechanism for an indoor elevator. The mechanism includes a fixed beam; two reversing pulleys;a lifting part which comprises a reel and a cable, wherein the reel is arranged between the two reversing pulleys and deviates from the midpoint of the connecting line of the two reversing pulleys, the cable extends upwards after being reversed by the two reversing pulleys, and the lengths of the cables on the two sides of the reel are different; a driving part that comprises a motor part and a connecting base, wherein one end of the motor part is connected with the reel, the other end of the motor part extends to the end, away from the reel, of the fixing beam, one end of the motor part is connected with the fixing beam through the connecting base, and the other end forms an indicating end; and a displacement monitoring piece, which is suitable for monitoring the displacement of the indicating end. The invention further provides a monitoring method, the displacement of the indication end of the motor part can be monitored, then the load of the lift car can be monitored, whether the lift car is overloaded or not can be stably and accurately monitored, and the problems existing in the prior art are effectively solved.
Description
technical field [0001] The invention relates to the field of household indoor elevators, in particular to an overload monitoring mechanism and monitoring method for indoor elevators. Background technique [0002] As a small indoor elevator for family use, the home indoor elevator is especially widely used in villas with 2-3 floors. Considering that the space occupied by the domestic indoor elevator cannot be too large, a kind of vertical guide rail without a shaft is generally arranged between the floors of the domestic indoor elevator, and the driving device of the indoor elevator moves together with the car of the indoor elevator. Specifically, a motor is used to drive a reel to retract and release two cables wound on two pulleys to realize the lifting of the domestic indoor elevator. In the existing domestic indoor elevators, the overload is mostly monitored by the load cell. Using this method, the sensor is in a repeatedly changing pressure environment for a long time, ...
