Embodiment 1

[0037] Such as figure 1 Shown:

[0038] The height adjustment method used in the coal panning system includes a preset step, a step of detecting the top of a coal pile, a height adjustment step, a scanning step and a reset step.

[0039] Preset step, according to the size of the coal pile, preset the height difference between the scanning device and the top of the coal pile when the scanning device scans, and store the preset height difference in the controller; and preset in the controller The rotation angle and rotation sequence of the pan-tilt and the scanning time of a single angle of the scanner. In this embodiment, the rotation angle and rotation sequence of the pan-tilt pre-stored in the controller are 45 degrees clockwise, and then 90 degrees counterclockwise. The preset scan time for all angles is 20 seconds. The height difference between the scanning device and the top of the coal pile can be set by those skilled in the art according to the specific scale of the co...

Embodiment 2

[0048] Such as figure 2 As shown, compared with the first embodiment, the loading vehicle 1 in this embodiment also has a balance bar 5 , an installation base 6 , a support spring 7 and a driving motor 8 .

[0049] Balance pole 5, balance pole 5 is electric push rod, and balance pole 5 has four, and the bottom of balance pole 5 is welded on the loading car 1, and balance pole 5 is electrically connected with controller, and the bottom of four balance poles 5 is connected successively Constitute a rectangle; In the present embodiment, the balance bar 5 is an electric push rod with a stroke of 500 millimeters customized by Zhongshan Elephant Electric Co., Ltd.

[0050] Mounting seat 6, mounting seat 6 is a sealed hollow cuboid, the four corners of the bottom surface of mounting seat 6 are hinged with the tops of four balance bars 5 respectively, mercury is housed in mounting seat 6, and welded on the internal side wall of mounting seat 6 Pressure sensor, there are four pressur...

Abstract

The invention relates to the field of coal checking systems, in particular to a height adjusting method for a coal checking system. The method comprises the steps that in the presetting step, according to the scale of a coal pile, the preset height difference between a scanning device and the top of the coal pile is preset when the scanning device conducts scanning; in the step of coal pile top detecting, the top height of the coal pile is detected; and in the height adjusting step, the position of the scanning device is adjusted to the position above the coal pile, and the height difference between the scanning device and the top of the coal pile is equal to the preset height difference. Compared with direct measurement in the prior art, according to the method, before scanning, the position of the scanning device is adjusted, the scanning device is located at the position where high-quality scanning and shooting can be conducted, high-quality scanning and shooting can be conducted each time, the coal checking result is more accurate, and stability is better.

Description

technical field [0001] The invention relates to the field of coal panning systems, in particular to a height adjustment method for the coal panning system. Background technique [0002] Coal counting refers to an inventory of the amount of coal stored in the power plant. Only when the coal counting work is done well can the power plant make a feasible plan for coal consumption for power generation. [0003] At present, coal panning is mainly assisted by scanning devices. After piled into a relatively regular shape with a bulldozer, the scanning device is used to scan and measure the coal pile to obtain the volume of the coal pile, which is then multiplied by the density of the coal pile to obtain the stored coal. quantity. [0004] However, when scanning, the current method basically installs the scanning device directly on a mobile tool, such as a bucket wheel machine or a loading vehicle, and then moves and scans. The advantage of this is that the coal pile can be scanned...
