Abstract

(57) [Summary] [Purpose] The present invention provides an automatic pile amount measuring device that can relatively accurately measure the pile amount without requiring human labor. [Structure] A light wave distance detector that measures the stacking height over the entire width of the pile is installed on the body of a stacker or reclaimer that operates to stack or discharge coal in a coal storage yard. In combination with the travel distance detector added to the coal storage yard, the amount of piles in the coal storage yard can be automatically measured while the stacker or reclaimer is running.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention automatically measures the amount of piles of stackers and reclaimers in coal storage yards. It can also be applied to automatic measurement of piles of bulk materials.

0002

[Conventional technology]

The pile amount in the coal storage yard is determined by a measuring device installed on the yard conveyor. It is calculated by calculating the difference between the loading amount and the unloading amount, but the amount of load shifting due to wind and rain In order to correct such factors, a person re-measures the amount of piles with a tape measure at regular intervals, and obtains an accurate amount of piles. I understand.

0003

[Problem that the idea aims to solve]

Calculation using a measuring device installed on the conveyor shows the amount of change due to the collapse of the pile, etc. cannot be calculated. Furthermore, the manual measurements that are being taken to compensate for this are accumulating. Since the length is about 50m to 300m, it requires a lot of effort and results. The resulting measured value will also not be accurate.

0004 The present invention is an automatic method for measuring the amount of piles that can relatively accurately measure the amount of piles without requiring human labor. The purpose is to provide a device.

[0005]

[Means to solve the problem]

The piles on the body of a stacker or reclaimer operating in a coal storage yard are seen from above. A height detection device based on a light wave rangefinder will be installed at a location where A mileage detector is installed in the running device, and while the stacker or reclaimer is running, By detecting the height of the top surface of the pile on the machine and combining each value, Accurately measure the amount of coal piled up.

[0006]

[Effect] Attach a light wave distance meter to the tip of the boom of the stacker or reclaimer, and use this light wave Scan the distance meter in the width direction of the pile, which is perpendicular to the direction of travel. at a certain angle Correct the distance measured to the surface of the pile by a light wave distance meter using the angle at the time of measurement. Then, the vertical distance from the optical distance meter to the surface of the pile can be determined. Equipped with a light wave distance meter The stacker or reclaimer rides on the rails of the coal storage yard, and the rail installation height is the same as that of the storage area. The height is the same as the coalfield standard height. Therefore, the distance between the light wave distance meter and the surface of the mountain is By measuring the distance, the height of the pile from the standard height of the coal stockyard can be determined. .

[0007] The measured value of the pile height can be obtained in the width direction of the pile by scanning a light wave distance meter. Measurement values can be obtained at regular intervals, and by running the stacker or reclaimer, Measurement values can be obtained at regular intervals along the length of the pile. These width and length measurements are respectively By approximating and combining the measurement intervals, a value for the plane can be obtained, and this value From this, it is possible to measure the volume of the pile, that is, the amount of pile.

【Example】

The present invention will be explained in detail below based on examples. Figure 2 shows the implementation of the present invention. This is an example of a coal storage yard, where a stacker or truck runs on rails 2 along a coal storage yard 1. It is composed of a reamer 3 and a yard conveyor 4 used for receiving and discharging coal. Ru.

[0009] Figure 3 shows the stacker 3 and the pile of coal 5 from the side, and shows the top of the rail 2 of the stacker 3. Equipped with a conveyor 8 that can be raised via a rotating frame 7 on a running traveling gantry 6 A boom 9 is provided. In the case of a reclaimer or a machine that combines a stacker and a reclaimer In this case, a bucket wheel is further provided at the tip of the boom 9, but it is omitted in Fig. 3. .

0010 FIG. 1 shows an embodiment of a pile height detecting means provided on the body of the upper surface stacker 3. In the figure, a light wave distance meter 10 and a scanning device 11 are installed at the tip of the boom 9, and the The row gantry 6 is equipped with a travel position detector 12. The detection points in the width direction of pile 5 are fixed for a certain period of time. A control device 13 installed on the body of the stacker 3 controls the measurement at intervals of, for example, 1 m. By controlling the measured distance and correcting the scanning angle, the surface of pile 5 and the light wave distance meter can be measured. At the same time, the vertical distance from the travel distance detector 12 is calculated. The traveling gantry 6 calculates the distance from the reference point 14 of the coal storage yard 1 and calculates the distance from the reference point 14 of the coal storage yard 1. Find the height of measurement point 15. The optical distance meter 10 is continuously accumulated by the scanning device 11. Scan the pile 5 in the width direction, and at the same time move the traveling gantry 6 to the length of the pile 5. The surface height of the pile 5 can be measured continuously by moving the pile 5 continuously at a slow speed in the direction of the pile. The amount stored in the pile 5 in the coal storage yard 1 is automatically measured based on the result.

[Effect of the idea]

The automatic pile amount measuring device in a coal storage yard according to the present invention can be used in a coal storage yard. , a stacker or reclaimer operating for loading or unloading coal. The machine is equipped with a light wave distance detector that measures the stacking height over the entire width of the pile. In combination with the mileage detector attached to the coal storage yard, it is possible to measure the amount of piles in the coal storage yard. We decided to automatically measure while running the stacker or reclaimer. This has the following effects.

0012 (1) The amount of piles in a coal storage yard can be reduced by simply running the stacker once in the length direction of the pile. It is possible to accurately grasp the amount of piles. (2) This allows comparison with the calculation results obtained from the conveyor scale, The reliability of conveyed amount also increases. (3) Only one driver of the stacker can correct the amount of piles piled up after loads have collapsed due to wind and rain. I can understand it accurately.
