Description

A laser measuring device for automatic elevator guide rail distance

technical field

The utility model relates to the technical field of special equipment measurement, in particular to a portable laser measuring device for the guide rail distance of an automatic elevator. Guide rail movement for elevator track gauge measurement.

Background technique

The installation accuracy of the elevator track gauge is closely related to its ride comfort and safety. Simple and efficient measurement of elevator gauge is a new requirement of the era for the elevator installation and inspection industry. According to the requirements of GB7588-2003 "Code for Elevator Manufacturing and Installation", the deviation of the main rail is within 0 to +2mm, and the deviation of the auxiliary rail is within 0 to +3mm.

The traditional elevator guide rail gauge is measured by two measurers on the top of the car with a steel tape. This measurement method has many defects: 1. The change of the use environment and the natural wear of the steel tape during use will cause changes in the measurement accuracy; 2. When using a steel tape to measure the gauge, the steel tape is usually passed through the steel wire rope or compensation chain, and it is difficult to ensure that the steel tape does not produce curling and leveling; 3. The accuracy of the measurement personnel’s reading is greatly affected by the viewing angle; 4. The inspection personnel in the car Sampling measurement on the top is inefficient and cannot be measured continuously.

The Chinese Utility Model Patent No. 201320442868.8 discloses a device for measuring the gauge of elevator guide rails. Using this device to measure has obvious advantages compared to using a tape measure, but this device still has some defects. When measuring the gauge, there are gaps between the car top guide rails The barrier of the steel wire rope, the use of this device must pass through the steel wire rope, which brings some troubles to the measurement. In addition, the device can only be installed on the top of the elevator car to measure the gauge of the main rail, and cannot measure the gauge of the auxiliary rail on the counterweight side .

The current method of measuring the speed of the elevator is to measure the speed of the steel wire rope in the machine room by the surveyor with a tachometer in hand. This measurement process requires the surveyor to operate the whole process, which is time-consuming and laborious.

The portable laser range finder has the characteristics of high precision and convenient use, and is widely used in life, production and equipment installation projects. If the range finder is held by the inspector or installed on the car top guide rail surface, it will be limited by the obstruction of the steel wire rope and cannot be realized. Even if it can be realized, the method is still time-consuming and laborious. Ordinary laser range finders can only be triggered manually and cannot be installed on the car bottom. However, the laser measuring device for elevator guide rail distance of the utility model is installed on the car bottom, which can automatically trigger measurement and stop, and store data.

The casing of the automatic laser range finder is provided with a rotating arm, which is connected to the speed sensor, and a spring is arranged between the rotating arm and the housing, and the rotating arm is close to the guide rail under the action of the spring; the automatic laser The rangefinder has a built-in automatic trigger circuit unit and a speed measurement circuit unit, and the speed sensor is directly connected to the speed measurement circuit unit. The utility model device is installed on the car bottom guide shoe or the counterweight guide shoe, and moves along the track under its traction. When the car or the counterweight starts to move, after the speed sensor detects that the speed is not zero, the automatic laser The rangefinder starts sampling and measuring the track gauge according to the set frequency and records the value, and at the same time measures the moving speed of the car and the counterweight. After the car or the counterweight stops moving, the rollers stop rotating, the speed sensor detects that the speed is zero, and the sampling measurement is stopped. Compared with the traditional measurement method, the new type has higher efficiency and more accurate measurement results, and is not limited to the subjective and objective factors of the work site and the measurement personnel.

As a preferred solution, a horizontal bubble meter is arranged on the housing of the automatic laser rangefinder, and the horizontal bubble meter can be used to calibrate the levelness of the installation of the device and reduce measurement errors.

The utility model adopts the mature principle of laser distance measurement, and is developed on the basis of the ordinary portable laser rangefinder. Limited to the conditions of the car top work site, no human operation is required, saving labor; 2. The measurement accuracy is high, and the number of sampling points can be set arbitrarily to realize measurement and data storage. 3. The measurement efficiency is high. It is installed on the bottom of the car, and it can automatically measure and record all the guide rail distances except the top section by following the car up and down once. 4. Various uses, following the car or counterweight, while measuring the gauge, it can accurately measure the up and down speed of the elevator.
