The utility model discloses a weighing transducer transmits the detected signal for the PLC circuit in the switch board, and PLC circuit control driving motor rotates to it removes corresponding displacement volume to make the screw drive the balancing weight, the utility model discloses simple structure, the suitability is strong, and the convenience is operated, has effectively improved the life of elevator, has improved the factor of safety that the elevator used.
Description
Technical field
The utility model belongs to a kind of counter weight device, is specifically related to real-time adjustment counter weight device and the control method thereof of elevator.
Background technology
The vertical conveyor of elevator to be a kind of with electrical motor be power, is equipped with box like gondola, takes advantage of people or carrying goods for tier building.Serve the fixed type lifting equipment of regulation floor.Vertical lift elevator has a car, operates in the vertical or leaning angle of at least two row and is less than between the rigid guideway of 15 °.Car size and version are convenient to passenger and are come in and gone out or handling goods.Elevator can divide slower elevators (below 1 meter per second), express lift (1 ~ 2 meter per second) and express elevator (more than 2 meter per seconds) by speed.
The development of random society, high buildings and large mansions stand in great numbers, and elevator, as a kind of vehicle shuttled back and forth between mansion floor, has become indispensable.But position time people take elevator under normal circumstances in elevator is unfixed, the suffered power of elevator is so also just caused not balance, what elevator was in that unbalanced working condition can cause elevator for a long time leads boots serious wear, and there is certain danger.
Summary of the invention
The utility model proposes for solving prior art Problems existing, its objective is the real-time adjustment counter weight device providing elevator.
The technical solution of the utility model is: the real-time adjustment counter weight device of elevator, comprise the car of vertically movement, multiple weight sensor is provided with in car floor, the lower surface of car floor is provided with stay bearing plate, be embedded with bearing in the through hole of stay bearing plate, be provided with leading screw in the inner ring of bearing, the screw on leading screw is connected with clump weight, described leading screw is driven by drive motor, and drive motor, weight sensor are all connected with the PLC control circuit in control housing.
Described drive motor is arranged on the lower surface of car, and the main shaft of drive motor is by coupler or gear drive leading screw.
Described drive motor is arranged on the side-walls of car, and the main shaft of drive motor drives leading screw by helical bevel gear.
Described leading screw center of gravity and the center of gravity line of car floor are vertical straight line.
The two ends horizontally set of described leading screw, longitudinally setting or diagonal angle are arranged on the lower surface place of car floor.
Described bearing is cylindrical roller bearing, Biserial cylindrical roller bearing.
Detection signal to be passed to the PLC circuit in control housing by the utility model by weight sensor, PLC control circui drive motor rotates, thus make screw drive clump weight to move to corresponding displacement, the utility model structure is simple, applicability is strong, handled easily, effectively improves the service life of elevator, improves the safety factor that elevator uses.
