Laser control ground water-saving technology is currently the world using an advanced and mature land leveling technology. Bobcat skid laser grader grader with ordinary large difference in real-time precision instrument calibration can be achieved by highway drainage standards, not only flat, but also for other road maintenance operations. Today repair-guidebook.com to introduce a Bobcat skid laser grader using the tutorial to see how this highly efficient technology for ground operations.
1 laser grader works
Laser Grader includes: transmitter, receiver, control box, hydraulic mechanism and scrapers. Principle is rotating laser transmitter emits light in the operating block to form a light plane, this is the leveling of the reference plane smooth, flat surface can be inclined. Laser receiver mounted on the skid steer loader grader. When the receiver detects the laser signal, continuously sends a signal to the control box. Control box receives the signal, correction, corrected signal control hydraulic valves, hydraulic oil output in order to change the flow and flow to the cylinder, automatic control scrapers scoop height.
Preparing for use points:
1, before use make sure the host matches 84 inches plate laser grader and functional.
2, in accordance with the requirements of the following equipment is installed
(1) laser transmitter battery capacity adequate, does not recommend the use of domestic battery.
(2) transmitters fixed Fortunately tripod, make sure foundation stability, and is probably the horizontal position, the transmitter has automatic leveling system functions.
(3) mounted on the receiver plate column Stabilize the sides and at the same height, the proposed receiver is higher than the skid steer loader cab 30CM, up to 360 ° so that the acceptable range.
(4) is ready pole foot, removable hand-held laser receiver and handheld remote control.
(5) suitable for precision flat places.
(6) Use the standard host work auxiliary flow for standard ground when using a continuous flow switch function.
Basic settings: the transmitter and receiver height values
Must be pre-set level points: In any case, the laser transmitter and receiver are always at the height of a parallel line, irrespective of the ground level, the receiver is automatically controlled within the range of 8 inch. The working of the laser transmitter
First X-axis and Y-axis values are 0, set a value if it is still started again before the value is off, it does not matter even remove the battery.
Basic settings: laser transmitter Placement direction specified
XY values set when the transmitter: X value must be in the A and C axis, the Y values must be in the D and B axis, injection (if the condition of horizontal space need not follow this requirement).
The first mode: complete horizontal operation state setting
If you need a fully horizontal flat site, you need to adjust the value to 0 XY values, if more than a single earthwork bulldozing plate capacity, the proposed slow increase or decrease the level of the laser transmitter rotating rod (recommended hardware for a single soil times 2CM, soft soil resistance based on size), the laser transmitter is placed in any position within a predetermined range (until the required X and Y axis direction), specify the acceptable radiation, the level of the ground to provide full functionality.
The second mode of operation: single-slope operation state setting
If a single ramp formation conditions, the need to adjust the values for the slope size X + or -, the specified values, Y has a value of 0. In the laser transmitter ramp degree range classes, such as motor graders, 200 meters away on a slope point, then adjust the transmitter and receiver point X axis ray radiation must look on the ray as an acceptable (see How to Find ray on a plane), the emitter of the high level ground better please, note the transmitter in the axial direction, set the acceptable radiation after leveling ramp function can be realized.
The third operating modes: two-sided ramp work status settings
If you need a double-sided flat slope conditions, the need to adjust the value of X +, or the size of the slope – the specified value, the slope of the X value is adjusted to the size of the + or – the specified value. In the laser transmitter ramp degree range category, for example, the first step to find outside of the X-axis rays 200M point, the second step in setting looking Y axis 200M ray point, (see how the rays in a plane on the setting method), the transmitter is located in the high places of the ground better, pay attention to the direction of the axis of the transmitter, set the acceptable radiation, you can achieve double-sided slope leveling feature.
How to rays in a plane setting method
In any case (not including more than the maximum angle transmitter), are required at the launch point and receiving point to an acceptable line, the transmitter automatically conducting angle adjustment after leveling, and then use the hand-held laser receiver to find the X or Y laser rays, high and low level if errors can be laser transmitter buttons to adjust the X or the Y, you can also use a hand-held remote control to make adjustments (effective distance 100M inside).
Laser Grader is more suitable for the following operations: stadium construction, the new paved road infrastructure in rural areas, urban plaza construction, residential square, a large plant foundations, and other high-precision formation works for industries with high technological requirements, time requirements liberal project. I believe that through the introduction of small series, everyone on this Bobcat skid laser graders learned more about and understand its working condition, currently in the country, there are many sites on the application of this laser grader technology, and large grader comparison, this higher accuracy grader flat, leasing costs are relatively low, users can save costs.
