A3. The master controller 1 judges the balance coefficient of the currently detected elevator according to the acquired data, and compares the balance coefficient with the preset balance coefficient threshold to determine whether the balance coefficient of the currently detected elevator meets the requirements.

Specifically, the traction-driven elevator mainly relies on the counterweight device to balance the weight of the elevator car and part of the load. Bottom (the weight of the counterweight device is too light, generally occurs after the use of the elevator, after the decoration of the car, such as the installation of air conditioners, marble floors, wooden walls, damage and loss of counterweights, etc.) accidents. Therefore, the balance performance of the elevator must be accurately monitored regularly.

In step A1, a certain amount of cast iron weights with a single mass of 20kg and 25kg can be divided into 5 times (0.3 times the rated load capacity, 0.4 times the rated load capacity, 0.45 times the rated load capacity, 0.5 times the rated load capacity, and 0.6 times the rated load capacity).

Specifically, the speed limiter and safety gear of the elevator are a set of safety protection devices for the elevator. The speed limiter plays the role of monitoring the running speed of the elevator. The safety gear is installed at the bottom of the car and meshed with the guide rail of the elevator. When the speed exceeds a certain range of the rated speed, the speed limiter will operate. The first action is the electrical switch. If the elevator needs to run at an urgent speed, it will trigger the action of the safety gear, clamping the elevator guide rail and finally stopping.

For the car load using the instantaneous safety gear is the rated load, and the over-area freight elevator should calculate the specified load according to the actual area of the elevator car. For the progressive safety gear, 1.25 times the rated load should be loaded. Control the operation of the elevator again, and control the electrical switches of each test through the self-triggering device 7, thereby carrying out the detection of components such as each electrical switch, speed limiter, safety gear one by one.

3. Traction performance test:

Specifically, whether the elevator can run safely and reliably has two important aspects: the traction performance and the braking performance of the elevator. It involves the whole life cycle of elevator products, and is an important safety guarantee measure, which is interactive and inseparable. Whether the traction and braking performance is effective is the key link to ensure that the elevator control system and operation instructions can be executed reliably, and it is also an important factor affecting the ride comfort.

The traction force of the elevator comes from the friction between the traction wire rope and the wheel groove of the traction wheel. The traction performance guarantees the dynamic safety of the elevator and is the most basic condition for the elevator to run. Sufficient traction must be provided under these conditions. The braking performance is to ensure the safety of the elevator when it is static, and to ensure that the elevator can reliably and smoothly stop at the designated position. Therefore, the brake is the most important component for the elevator to achieve reliable braking. In recent years, there have been frequent elevator injury accidents caused by hidden dangers of brakes, and it is imperative to strengthen the safety status inspection of elevator brakes. The braking capacity is the ultimate reflection of the technical status of the elevator brakes, and the checking of the braking capacity is an essential technical means to prevent accidents caused by elevator slipping and ladder injuries.

The braking performance of the elevator mainly depends on whether the application of the braking force is appropriate. If the braking force is insufficient and the deceleration is small, the braking distance will be too large. , opening the door and sliding the car, etc.), and the longer the duration, the more dangerous; if the braking force is too large, the deceleration is large, the braking distance is too small, the impact force is large when braking, or even the Causing personal injury to passengers in the car. If there are problems with these two major performances, it may lead to serious casualties and damage to the equipment body such as sliding ladders, climbing to the top, squatting, shearing, and extrusion.

In the test of this embodiment, the traction performance test of the elevator is completed by using the general controller 1, the positioning device 6, the monitoring and identification device 5, the elevator driving measurement device 2 and the elevator operation performance acquisition device 3.

Test process: The elevator goes up during maintenance, and the limit switch, limit switch, and buffer switch are triggered successively. It is necessary to short-circuit and fail the operation of these switches, and then the maintenance continues to go up. The judgment index of the traction performance of the elevator is: when the elevator counterweight device completely compresses the buffer, the car cannot be continuously lifted, and the traction machine slips or does not rotate (depending on the joint determination of the positioning device 6 and the elevator driving measuring device 2).

Test process: the elevator goes up and down at normal speed, and reaches the predetermined position (judged by the positioning device 6) to trigger the stop switch (the triggering action is realized by the trigger device 7). The judgment index of the braking performance of the elevator is: the elevator car finally stops (the general controller 1 judges by the data collected by the positioning device 6 and the elevator drive measurement device 2), and the driving host stops running (the general controller 1 passes the elevator Drive the collected data of the measuring device 2 to judge).

Only by being able to measure, be able to measure and accurately measure can the subsequent design, installation and manufacturing process be carried out smoothly. In the elevator safety accidents, falling into the shaft and shearing the door area are the most dangerous accidents. Emergency rescue after the accident is particularly important. Therefore, it is necessary to monitor the status of the elevator shaft and provide early warning when any physical changes in the shaft are found.
