Problems solved by technology

Usually, the crane track parameter measurement is carried out after the crane is shut down. The total station, level, theodolite and other instruments are used to measure each point on the track one by one to obtain the required track parameters; but the shutdown measurement seriously affects the normal production order, and The traditional measurement method is inefficient and requires a lot of manpower, most of which are high-altitude operations, and there are certain safety hazards

Embodiment Construction

[0017] Implementation example figure 1 As shown, the crane track online detection method of the present invention includes the following steps:

[0018] Step 1. Establish a collimation reference system. Set up a laser collimator 3 at one end of the rail 21 on the motor track side of the crane 1, and set a fixed laser receiving target 4 on the other end of the track 21 at the same level as the laser collimator 3, and fix it The laser receiving target 4 receives the laser spot signal of the laser collimator 3 and corrects the laser drift, and uses the linear collimated laser of the laser collimator 3 as the reference reference for the detection of the entire crane track;

[0019] Step 2: Set the mileage sensor 5 at the position of the anti-collision device of the crane 1 to accurately measure the distance between the crane 1 on the track and the end of the track, and perform the mileage measurement of the crane 1;

[0020] Step 3. Set an automatic lifting mobile laser receiving target...

Abstract

The invention discloses an online detection method for crane tracks. The method comprises that the track at the triboelectric side of a crane is provided with a laser collimator and a fixed laser reception target to establish a collimation reference system; and the crane is provided with a mileage sensor, a mobile laser reception target, a laser displacement sensor and a one-dimensional inclination sensor to measure mileage data, real-time displacement data, data of distance between the tracks, the track linearity data, relative elevation data of the tacks and relative height difference data of the tracks in real time, and thus, the crane tracks are detected in real time. The crane and the tracks are provided with the corresponding measuring components, the movement locus of the crane and the relative relation between the crane and the tracks are measured to obtain track parameters, the production order is not interfered, the measuring efficiency is improved, and safe and reliable operation of the crane is ensured.

Description

Technical field [0001] The invention relates to an online detection method for crane tracks. Background technique [0002] The crane is a special equipment, which uses the track as a support and walks on the track during lifting operations. Therefore, the height deviation and horizontal deviation of the crane track, as well as the span difference and height difference between the left and right tracks, are essential to the safe operation of the crane. Generally, crane track parameter measurement is performed after shutdown, and total station, level, theodolite and other instruments are used to measure each point on the track one by one to obtain the required track parameters; but the shutdown measurement seriously affects the normal production order, and Traditional measurement methods are inefficient and require a lot of manpower. Most of them are high-altitude operations, which poses certain safety risks. Summary of the invention [0003] The technical problem to be solved by t...
