2. Driving body: The driving body is a component connecting the driving unit and the whole structure. It transfers the driving force generated by the driving device to the hanging cage, so that the hanging cage can run up and down.
3. Driving unit: The driving unit makes the power part of the elevator run, driving the self-weight part of the elevator and the load (or construction personnel) in the hanging cage to run up and down. The driving unit consists of a driving gear, a reducer, a coupling, an elastic block of a quincunx coupling and a brake motor. The reducer is a dry bread worm reducer with compact structure, high bearing capacity, high mechanical efficiency, long service life and stable operation. The coupling is a bent claw type, and a rubber buffer block is installed between the two couplings to reduce the impact and vibration during operation. The motor is YZE 132L-4 lifting disc brake three-phase asynchronous motor, and its braking electromagnet can automatically track with the wear of the brake disc, and the braking torque is adjustable.
4. Electrical system: The electrical system is the mechanical command part of the elevator, and all actions of the elevator are commanded by the electrical system, including the power-on box, the power-off box and the control cable.
5. Seat plate of safety device: The seat plate of safety device is the connecting part between safety device and other structures, and it is equipped with national patent anti-falling safety device. If the hanging cage falls over speed due to unexpected reasons, the seat plate of the safety device can bear the impact force generated when the hanging cage stops.
6. Anti-falling safety device: SAJ3.0- 1.2 Anti-falling safety device is a national patented technology product, which adopts advanced technologies such as throwing a block to bite people without impact and checking the wear of the friction brake belt without disassembling the machine. When the hanging cage accidentally falls over speed, it can stably stop on the guide rail frame, cut off the control power supply, and ensure the safety of personnel and equipment. The excitation speed of the safety device has been adjusted correctly and sealed with lead before leaving the factory. Users are not allowed to open the safety device without authorization, otherwise the service life will be marked on the nameplate of the safety device at their own risk. When the service life is reached, it should be sent to the manufacturer for re-calibration and calibration. The collision limit block ensures that when the cage continues to run after the limit switch fails after running to the upper and lower limit positions, it will immediately cut off the main power supply to stop the cage from running, and ensure that the cage will not fall off the top when going up and hit the bottom when going down. The limit switch is not automatically reset.
7. Limit device: The limit device includes up-and-down stroke limit buffer and up-and-down stroke limit buffer. The upper and lower travel limit buffer of the car ensures that when the car moves to the upper and lower designated positions, the power supply will be automatically cut off, so that the elevator stops running. It can only be reset by manual operation. Always check whether the position between these bumps and the corresponding switches is accurate, so as to ensure the accurate action of each switch.
8. Power box: The power box is the heart of the elevator electrical system, which is mainly equipped with up-and-down contact sequence, control transformer, overheat protector, open-phase and phase sequence protection relays. The upper electrical box is installed in the hanging cage.
9. Hanging cage: control transformer, overheat protector, open phase and phase sequence protection relay, etc. The upper electrical box is installed in the hanging cage. The hanging cage is a fully enclosed structure made of section steel, steel wire woven and steel plate welded. The upper and lower floors are patterned steel plates, and the top is provided with an exit door for people to enter and leave the hanging cage for everyone to use. The entrance door of the car is a self-falling door, and the exit door is a turnover door. The cage is equipped with an electric interlocking device. When the cage door is opened, the cage will stop working to ensure the safety of people in the cage. There are 12 guide rollers running along the guide rail frame on the hanging cage.
10. Power box: The power box is the power supply of the elevator control part, and all operating switches are located in the ground operation box.
1 1, underframe guardrail: mainly including underframe and guardrail. (1) The underframe is made of section steel (channel steel) and steel plate by tailor-welding, which is connected with the ground fence around, with the guide rail frame base in the middle. It can bear all vertical loads transmitted by the elevator. During installation, the underframe is anchored with the concrete foundation of the elevator through anchor bolts. (2) Protective fence: it is welded by angle steel, steel plate and steel wire woven net, and forms a closed area around the elevator main engine, so that personnel are not allowed to enter the area when the elevator is working. There is a guardrail door at the population of the fence, and the door is equipped with an electromechanical interlock device.
12. Cable reel: Cable reel is a component used to receive and release the main cable. When the hanging cage moves upward, it drives the main cable in the cable drum to move upward, and when the hanging cage moves downward, the main cable is slowly stored in the cable drum to prevent the main cable from being scattered on the ground and crushed.
13, cable guide: Cable guide is set to protect cables. When the elevator is running, make sure that the cable is in the holder of the cable guide. During the operation of the cage, the cable guide can prevent the cable from being entangled with other nearby equipment. When installing the cable guide frame, ensure that the cable arm and the main cable can smoothly pass through the fixer on the cable guide frame.
14. attachment device: the attachment device is a connecting part between the guide rail frame and the building, which is used to maintain the stability of the elevator guide rail frame and the overall structure. In addition, the connecting device also provides an installation position for the cable guide frame.
15. Cable hanger: Cable hanger is a device that drags the main cable up and down. The main cable is pulled by the cable hanger, which can safely pass through the fence retainer to prevent the cable from being scratched and causing accidents. In addition, the cable hanger can also pick out the main cable from the bottom guardrail, so that the main cable can be safely collected in the cable drum.
16. Manual crane: Manual crane is an indispensable part to realize self-help lifting and self-help disassembly of elevator. When the basic part of the elevator is installed in place, the crane can be used to lift the top of the car and the standard section in the car to the top of the installed guide rail frame for lifting operation. On the contrary, when dismantling, the manual crane can dismantle the standard section of the guide rail frame from top to bottom in turn.
