Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compaction machine that compacts a road surface to be compacted into a desired pattern. Before paving with these paving materials, a layer of gravel is placed on the road surface and compacted using a compaction machine to form a foundation, and then a layer of asphalt etc. is laid on top of it and compacted. , compact and pave.

If the rolling pressure is not uniform and sufficient, cracks will occur on the pavement surface, and problems such as peeling and sinking will occur later.

Therefore, it is required that the rolling compaction of the road surface pavement be uniform and sufficient, but in general, the degree of compaction of the pavement surface by the rolling machine is determined by the number of rollings by the rolling machine in the construction specifications, i.e. It is often managed by replacing it with the number of times the rolling machine passes the road surface, and the number of rolling rolls of 70 is very uneven in some parts.

In other words, the fact is that the number of passes of the rolling compaction machine is left to the driver's memory, and the forward and backward traveling distances also depend on the driver's visual estimation and memory, so it is inevitable that the rolling machine will The current situation is that it is extremely unclear whether it is possible to manage the compaction level evenly due to the partial unevenness of the number of times of compaction.

In view of the above-mentioned circumstances, the present invention aims to provide a rolling compaction machine that uniformly compacts the road surface to be compacted into a desired pattern using an automatic control method, and the steering angle of the steering wheel is changed by changing the cylinder stroke. The steering cylinder is equipped with a steering cylinder installed to arbitrarily change the steering angle, an angular displacement detector that can detect the steering angle, and a rotation sensor that detects speed and travel distance. The present invention is characterized in that it includes a means for automatically controlling the working process according to the desired rolling pattern obtained.

With the above-described configuration, the present invention divides the road to be compacted into a desired compaction work stroke pattern in advance, and the compaction machine consists of a series of forward movement, stoppage, retreat, route change, and stop in the compaction work process pattern for each division. The operation is converted into data, and the data is stored in an automatic control management device mounted on the compaction machine, and the road surface to be compacted can be compacted using the automatic control method of the automatic control management device. As shown in the figure, the rolling machine can automatically and uniformly perform the rolling work over the entire road surface, regardless of the skill level of the driver.

The above (1%-9 example of the Sansakuan process flow diagram is the 4th example)
There are things like wards. This is done by dividing the road I to be rolled into parallel rectangles along its length at regular distances Lf, setting rolling blocks, An appropriate number of travel lanes are set depending on the wheel width, and each travel lane is sequentially rolled for each rolling block.Each symbol in Fig. 4 has the following meaning. .

B indicates the road width, and point P-Pa is the rolling pressure base point. Lf is a constant distance of the rolling block, and partition points P and P are set every -2 distance Lf.
...Pl and Pa-Pa-Pa-Pa are set. Points P, -P, . . . P are the base points of the driving lane.

Lr is the distance to retreat from the end of the current driving lane to the starting point of the next driving lane, and the forward distance @L f - L r = △ of △L
The driving lane reference point moves forward by L. Therefore, distance Ls=number of running rays×ΔL. The distance T is the M line retreat distance, and the rolling machine 71 changes route to the next travel lane during the distance t. To store this information in the memory section of the microcomputer 17 of the automatic control V-embedding device of the rolling machine, the following steps are taken.

(3) With the above, base point P2 of 1s2 lane from the 1st rune
Therefore, give a steering angle correction command and a start command, and input the process described in item 1 above for the number of travel lanes, and if the number of rolling turns is 4 rotations, for example, reverse the travel lane, or The starting point line is point P - P'
It is possible to specify and store it as appropriate, such as reversing what was previously at point a and moving diagonally in the direction of point -P' a -P'.

If you make an input mistake, press the clear button to correct it.
