Description

  The present invention relates to a road surface processing machine. More specifically, the present invention relates to a road surface processing machine capable of cutting and grooming a road surface with a single machine.

  On roads, bridges, and airport runways, it is necessary to periodically perform repair work by removing old pavements and renewing them. To remove the old pavement, make a vertical cut of 20-30 cm in depth, then peel off the old pavement, construct a new pavement, and after the new road surface is completed, form a non-slip shallow groove on the road surface Grooming is performed.

  In the above-described vertical cutting work, a road surface cutter that uses a single cutter blade having a diamond tip fixed to a disk-shaped blade to make a deep cut is used. For grooming, a grooming machine that uses a grooming blade in which a plurality of diamond blades are mounted side by side to make a shallow cut is used.

  A typical configuration of a road surface cutter is as shown in Patent Document 1 and includes a traveling wheel on the lower surface of the vehicle body, and an engine, a motor, or the like as a driving source for traveling and cutting is mounted in the vehicle body. . A cutter drive shaft is attached to the lower surface of the vehicle body by a bearing, and one cutter blade is attached to one end of the drive shaft. When this cutter blade is rotated and deeply cut into the road surface, the road surface can be cut vertically.

  A typical configuration of the grooming machine is as shown in Patent Document 2, which includes a traveling wheel on the lower surface of the vehicle body, and an engine, a motor or the like as a drive source for traveling and cutting is mounted in the vehicle body. Yes. A cutter drive shaft is attached to the lower surface of the vehicle body by a bearing, and a plurality of grooming blades are attached to one end of the drive shaft. When the grooming blade is rotated and shallowly cut into the road surface, a plurality of anti-slip grooves are formed on the road surface.

  However, until now, only a road cutting machine and a grooming machine have been exclusively used, so a grooming machine was required in addition to the road cutting machine in order to complete paving work. There is no problem in having two types of dedicated machines for large-scale pavement construction, but for small-scale pavement construction, two types of dedicated machines will increase the construction cost, and grooming machines will be transported from other construction sites. There was also a problem that the construction period was extended if it took time to come.

  However, if vertical cutting and grooming of the road surface can be performed with one processing machine, the construction cost can be reduced and the problem of extension of the construction period can be eliminated.

A cutter drive shaft is attached to the lower surface of the vehicle body by a bearing, and one cutter blade is attached to one end of the drive shaft. When this cutter blade is rotated and deeply cut into the road surface, the road surface can be cut vertically.

Typical configuration of the glue-bi packaging machine is as shown in Patent Document 2, provided with wheels for running on the lower surface of the vehicle body, equipped with an engine and a motor or the like as a driving source for running and cutting into the body doing. Drive shaft for the cutter is on the vehicle body lower surface is attached by a bearing, it is mounted a plurality of glue bi ring blade on one end of the drive shaft. When this while rotating the glue bi ring blade to cut shallow road, non-slip grooves of plural rows on the road surface is formed.

However, so far because the only road cutting machine also glue bi-packaging machine also specialized machines did not exist, in order to complete the paving, etc., it was also required glue bi-packaging machine to the outside of the road cutting machine. Although there is no hindrance to equip of two special-purpose machine is a large pavement construction scale, or become high and construction cost align the special-purpose machine two in the scale is small pavement construction, the glue bi-packaging machine of other construction site There was also a problem that the construction period was extended if it took a long time to transport it.

However, if one of the machines in the slitting cutting and glue bi-ring of the road surface is Okonaere, construction costs can also be cheaper suppression, also eliminated a problem that the construction period extension.

A road surface processing machine according to a first aspect of the present invention is a road surface processing machine that performs longitudinal cutting of a road surface and grooving processing of the road surface, and the road surface processing machine has a rotational drive source mounted in the vehicle body and is used for cutting in the vehicle body. A bearing that selectively supports a drive shaft and a grooving drive shaft is attached, the cutting drive shaft is a drive shaft that rotates one cutter blade, and the grooving drive shaft is a plurality of grooving blades drive shaft der for rotating is, the cutting drive shaft includes a shaft portion supported by the bearing which is attached to the vehicle body, a pulley which receives the driving force from the rotation driving source with mounted on the bearing, A first blade attachment portion configured to hold one cutter blade at one end of the shaft portion, and the shaft portion, the pulley, and the first blade attachment portion are arranged in this order. Characterized in that it is.
A road surface processing machine according to a second aspect of the invention is a road surface processing machine that performs longitudinal cutting of a road surface and grooving of the road surface, and the road surface processing machine is equipped with a rotational drive source in the vehicle body and is used for cutting the vehicle body. A bearing that selectively supports a drive shaft and a grooving drive shaft is attached, the cutting drive shaft is a drive shaft that rotates one cutter blade, and the grooving drive shaft is a plurality of grooving blades The grooving drive shaft includes a shaft portion supported by the pair of bearings attached to a vehicle body, a pulley that receives a driving force from the rotational drive source, and one end of the shaft portion. A second blade attachment portion configured to hold a plurality of grooving blades in parallel at the portion, and the shaft portion, the pulley, and the second blade attachment portion are arranged in this order. It is characterized in that is.

According to the first invention, when the cutting drive shaft is attached to a pair of bearings, longitudinal cutting using one cutter blade can be performed, and when the grooving drive shaft is attached to a pair of bearings, a plurality of Grooving can be performed by forming a plurality of anti-slip grooves on the road surface with a single grooving blade. In this way, by selecting and mounting the drive shaft, it is possible to perform both road cutting and grooving while being a single processing machine, which is convenient for relatively small sites and construction costs. Can also be cheap.
Further, when the cutter blade is attached to the first blade attachment portion and the shaft portion of the cutting drive shaft is attached to the vehicle body with a pair of bearings, one road surface processing machine can be used as a road surface cutter.
According to the second invention, when the cutting drive shaft is attached to a pair of bearings, longitudinal cutting using one cutter blade can be performed, and when the grooving drive shaft is attached to a pair of bearings, a plurality of Grooving can be performed by forming a plurality of anti-slip grooves on the road surface with a single grooving blade. In this way, by selecting and mounting the drive shaft, it is possible to perform both road cutting and grooving while being a single processing machine, which is convenient for relatively small sites and construction costs. Can also be cheap.
Further, when a plurality of grooving blades are attached to the second blade attachment portion and the shaft portion of the grooving drive shaft is attached to the vehicle body with a pair of bearings, one road surface processing machine can be used as the grooving machine.
