JPS6036591A - Control device for transfer car attached to coke oven - Google Patents

Abstract

PURPOSE:To detect the present position of a transfer car and an amount of meandering of it, by setting two optical range finders at both sides of a travel path of a transfer car, reflecting projected light rays between the corresponding corner cube groups, detecting the reflected light rays. CONSTITUTION:The two optical range finders 3 and 3' are set at both sides of the travel path 1 of the transfer car 2, two pairs of the corner cube groups 4 and 4' corresponding to the optical range finders 3 and 3' are laid at the end part of the travel path 1, and the projected light rays 5 and 5' are reflected. The present position of the transfer car 2 is calculated from the average value of the detected values of reflected lights rays of the optical range finders 3 and 3', and the amount of meandering is detected from the variation of both the detected values.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for a moving vehicle attached to a coke oven.

[Prior art]

To operate a coke oven, a coal loading car and a guide car are installed inside the coke oven and move on a predetermined running path.

A moving vehicle body such as a pusher vehicle is used. It is necessary to control the positioning of these mobile bodies in correspondence with the plurality of carbonization chambers of the coke oven main body. For this reason, conventionally, an operator has controlled the operation of a mobile vehicle while directly visually checking the vehicle at the site.

However, operating a heavy moving vehicle properly along the entire length of a relatively long route in a poor work environment with high temperatures and dust places an excessive burden on the operator. There were also safety issues.

Furthermore, if these moving vehicles meander with respect to the surface of the coke oven body, there is a risk of damage to the operating parts, carbonization chamber, etc. of the moving vehicle body, but conventionally, there is no effective means to detect such meandering of the moving vehicle body. [Purpose of the Invention] Therefore, the present invention solves the problems in controlling a four-moving vehicle body equipped with a coke oven, and makes it possible to drive the vehicle while accurately grasping the position of the moving vehicle body without visual inspection by the operator. It is an object of the present invention to provide a complete control device for a moving vehicle body attached to a coke oven that can control and also detect meandering.

[Structure of the invention]

The present invention provides two light wave distance III's on both sides of the travel path of a moving vehicle body, and provides two sets of corner cubes corresponding to the light wave distance meter at the end of the travel path to reflect the projected light. The current position of the moving vehicle body is calculated from the average value of the reflected light detection values of both the light wave distance meters, and the meandering position is estimated from the deviation of these two side-out values.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to illustrated embodiments.

In the drawing, one embodiment f11 of the present invention is shown, but there is a rail A-
1 is laid, and the moving vehicle body 2 is able to run freely on this rail by means of an appropriate drive device (not shown).On both outer ends of the traveling rail 1 on the moving vehicle body 2, a light wave is applied. Distance meters 3, 3' are provided, and two sets of corner cube groups 4.4 are provided at one end of the running path on which the rail 1 is laid, corresponding to the light wave distance meters 3, 3'. It is being The light wave distance meters 3, 3' project the beams 5, 5' onto the corner and beam groups 4, 4', and measure the distance by receiving the reflected light.

A plurality of corner cubes are used as reflectors in order to be able to reflect the projected light from the light wave distance meter 3, 3' even if the moving vehicle l meanderes and the beam 5 deviates from its normal position. The corner cube groups 4 and 4' were combined.

Further, the light wave distance meter 3.3' is connected to a control device 6 provided on the moving vehicle body 2, and this control device 6 inputs the measured values of both the light wave distance measurements 3, 3'i5f and calculates an average value. Me,
The distance from the moving vehicle body 2 to the end of the road where the corner cube group 4.4' is provided is calculated.

Further, if the deviation of the input elbow measurement values exceeds the allowable value, the control device fi6 detects meandering of the moving vehicle body 1 and completely stops the drive device.

[For production]

When using this control device, when L1 is instructed to move to a desired position, the control device 6 operates the light wave distances i1-3, 3', and projects the corner cube group 4°4' laser beams 5, 5'. There, light wave distance meter 3,3
' calculates the distance from the reflected light to the end of the road where the corner cube groups 4, 4' are arranged.

The control device 6 obtains the distance to the end of the p1 travel road by inputting the measured values of the light wave distance meters 3 and 3' and calculating the average distance, and based on this, moves the moving vehicle lft to the desired position. let

During this operation, if the deviation of the measured value due to the light wave distance a=t''3,3' exceeds the allowable value, it is assumed that the moving vehicle body 2 is meandering, and the operation of the drive device is stopped.

In addition, the beams 5 and 5' of the light wave distance meters 3 and 3' run cleanly on the inside and outside of the travel path, and if an object enters the travel path and the beams 5 and 5' are interrupted. The control device 6U detects the intrusion of an object and stops the operation of the moving vehicle body l.
