Description

[Detailed description of the invention] This invention is based on a coke extruder, coal charging car, and
This invention relates to a work fixed position detection and stop device for coke oven working machines such as coke guide cars or fire extinguishing trucks.

In order to operate each device in a coke oven working machine in an orderly manner according to an automatic operation sequence, it is important that the coke oven working machine accurately detects its working position.

Normally, there are several hundred working positions in a coke oven at a pitch of 1 to 1.5 m, and known working position detection devices are used at each of the four working positions along the travel route.
A sensing piece was installed at each fixed position, and detection was performed using a proximity switch installed on the working machine.

Another method is to drive a pulse transmitter provided on the working machine in proportion to the traveling distance, and calculate and detect the pulse signal as a working position signal every four.

However, the position detection method using a combination of a sensing piece and a proximity switch is affected by expansion due to heat generated during coke dry distillation and cooling contraction due to coal charging. This requires positional correction, and the correction work is a mechanical adjustment work, which requires a great deal of labor and skill.

Furthermore, in the method of driving the pulse transmitter in proportion to the travel distance, position detection is performed according to a preset program, so position correction is required for each fixed work position.

Furthermore, for the automatic operation of coke ovens, detecting the working position requires a traveling detection accuracy of several millimeters or less, so it is extremely difficult to always maintain the predetermined accuracy at a large number of working positions. Even if a work position detection and stop device is installed for automation purposes, it is currently not fully utilized.

The present invention provides a position detection and stop device that eliminates the above-mentioned defects.Explaining the embodiment shown in the drawings, a coke oven 1 is usually installed in several hundreds of ovens. '2... are arranged horizontally, and a coke oven working machine 2 is arranged on the top and side of the coke oven 1. , a coke guide vehicle, a fire extinguishing vehicle, etc., and travels along the traveling rail 3.

Devices 4 for indicating the working position of the coke oven are provided every four along the traveling rail 3, and position detectors 5 are provided on the working machine 2 corresponding to the devices 4.

This position detector 5 detects the traveling position of the work machine 2 and the display device 4.
This is a device capable of detecting a running direction deviation with respect to the running direction, and is connected to a running direction deviation storage device 6, and a running drive control device 7 is connected to the storage device 6.

The output signal 8 of the position detector 5, the work fixed position stop signal 9, and the kiln number signal 10 are input to the storage device 6, and the deviation storage information is converted into an output signal 11 by the information reading device and sent to the traveling drive control device 7. It is guided and controlled to stop at a precise working position.

To give a concrete example, when the coke oven working machine 2 travels and stops at the #3 furnace, the work machine 2 moves along the traveling route (rail 3) to determine the working position of the #3 furnace. A display device (sensing piece) 4 is detected by a position detector 5 and a stop signal is issued.

On the other hand, the deviation storage device 6 has in advance written and stored the traveling deviation distance between the sensing piece 4 and the actual working position of the furnace 13 as an electric signal, and the deviation information reading device reads the deviation signal from the output signal of the position detector 5. By addition, an accurate working position signal can be given to the traveling drive control device 7.

Since the present invention is constructed as described above, it is possible to always detect an accurate working position and stop the working machine 2 at that position by storing as many travel deviation signals for each of the required number of kilns.

Therefore, unlike in the past, there is no need to mechanically adjust the position of the work position display device 4 (sensing piece), and it is only necessary to change the writing of travel deviation information in the storage device, making adjustment extremely easy and Since automatic adjustment is also possible in combination with a fixed position detection device, labor saving and automation of coke oven operating machinery is promoted, and its industrial value is great.
