Pantry elevator structure: (1) room parts: the motor, brake, reducer, and other mechanical traction wheel components. A, hoisting machine: the hoisting rope by friction and traction wheel drive machine to achieve the car is running. B, control cabinet: The cabinet has a PC microcomputer and a variety of relays, contactors, through various control lines and control cables, and the car or landing manipulate various control devices are connected to the tank in order to achieve the desired operation elevator, automatic control performance and security performance requirements. (2) the car: the elevator loaded cargo metal structures, which affect the car by means of the hoisting rope moves vertically along the rails, complete laden tasks. (3) the hoistway section: A, rails: for the elevator car and the counterweight provided guide member. B, buffer: Set in the shaft in the pit beneath the weight of the car and a cushioning device, when the car is broken rope overload occurs speeding out of control when declining or falling car or counterweight dampening effect. C, on re: its weight is to balance the weight of the car, improving the performance of a device for traction, relying on heavy rail moves vertically. D, limit switches: control of the elevator car is not allowed to cross a certain position of the upper and lower end of the station's operation, if the car hit the offside limit switch will cut off the elevator control circuit, the elevator stopped running. (4) landing part: A, landing door: in the hoistway floor stops at each floor has a landing door shall be fitted with electric interlocking and mechanical interlocking device on hoistway door. When the hall door, electrical interlock switch on the elevator to start, or can not start. The role of mechanical interlock is only in the car stopped at a floor stop at this one layer door to open, or not open. B, floor lamp: packed in layers above the door or the side, showing the direction of travel and the car where the elevator floor. C, call button, the control box: call button mounted on the floor side door; car outside operated control box mounted on the floor side door. Through the call button and the control box to control the operation of the elevator.
