Elevator weighing device detection equipment and method

Abstract

The invention discloses elevator weighing device detection equipment. The elevator weighing device detection equipment comprises a lever mechanism, a force applying device and a lever mechanism connecting device, wherein the lever mechanism is used for loading at the elevator rope head position, the force applying device is used for applying force to the lever mechanism, and the lever mechanism connecting device is used for fixing connecting the lever mechanism to the elevator rope head position. According to the detection equipment, when a weighing device is debugged or detected, weight blocks do not need to be moved into a lift car any more, and all loading operation can be completed in a machine room. The elevator weighing device detection equipment has the beneficial effects of being simple in structure, low in cost, small in weight, small in size, convenient to transport and the like; universality is high, the equipment can be applied to different elevator construction sites and most elevator types, and the reusing rate is high; and spot operation is convenient to operate, one-person operation is easy, loading is simple and quick, load continuous adjustment can be convenientlyand quickly achieved. The invention further discloses an elevator weighing device detection method.

Description

technical field [0001] The invention belongs to the field of elevators, and in particular relates to a detection device for an elevator weighing device. The invention also relates to a detection method for an elevator weighing device. Background technique [0002] The weighing device is an important part of the elevator system. It has the function of overload protection for the elevator and is extremely important for ensuring the personal safety of passengers, the goods being transported, and the safety of the elevator itself. In addition, the weighing device accurately feeds back the actual load in the car, which helps the elevator control equipment to accurately determine the starting torque of the traction machine, etc., and is conducive to improving the ride comfort of the elevator. [0003] Not only in the initial stage of elevator installation and commissioning, it is necessary to write scales to the weighing device, but according to the requirements of TSG T5001-2009...

AI Technical Summary

Problems solved by technology

If it is prepared on site (for example, making cement blocks on site), it is difficult to ensure accurate weight, and the reuse rate is also very low;

[0007] 2. During on-site operation, every time the load is adjusted, it needs to be carried by manpower, and the labor cost is high

It is very time-consuming and labor-intensive to carry heavy weights, and the efficiency is very low;

[0008] 3. Since each weight block has a fixed mass, the load mass cannot be continuously adjusted during the test;

[0009] 4. All the weights are placed in the car, and it is easy to cause damage to the surface of the car during the handling process

[0013] 1. It needs to be realized by very complex special equipment. Although it can be reused, such special equipment itself has high cost. Due to its large size and heavy weight, it is troublesome to carry and operate the equipment;

[0014] 2. The loading position is on the bottom of the car or on the top of the car, and it needs to be operated at the landing, while the control equipment of the elevator and the controller of the weighing device are generally located in the machine room

This makes operation cumbersome and difficult for one-person operation
