Description

The present invention relates to a compaction road roller used for compaction of a pavement surface.

Generally, when pavement work such as road surface is performed, pavement material such as gravel and asphalt mixture is spread on the leveled road surface, and then a rolling road roller is run to make the flatness of the road surface even. A method of compacting the pavement material is adopted (see, for example, Patent Document 1).

Further, in connecting the ends of the bridge girders, as a means for absorbing the expansion and contraction of the bridge girder due to changes in temperature and the deformation of the bridge girder due to the passage of vehicles, for example, as shown in FIG. A structure using (simply referred to as a "stretching device") 100 is known. The space at the end of the bridge girder on which the expansion / contraction device 100 is installed includes a space between bridge girders arranged in the direction of the bridge axis and a space between the bridge girder and the abutment. A pair of joints having comb-shaped surface plates 101a and 101b that mesh with each other are provided on the surface of the above. At the place where the expansion / contraction device 100 is installed, the operation of the rolling load roller is not properly operated and processed, or the finish (flatness) is greatly affected.

Japanese Unexamined Patent Publication No. 2000-336617

Therefore, the processing problem of compaction by the conventional compaction load roller of this kind will be described with reference to FIGS. 7 and 8.

FIG. 7 shows a state when the compaction road roller 110 is moved toward the end of the bridge girder in which the expansion / contraction device 100 is installed, that is, in the pavement construction direction indicated by the arrow X in FIG. There is. When rolling around the expansion / contraction device 100 installed at the end of the bridge girder, the compaction load roller 110 performs the compaction work while pushing the asphalt mixture, so that when passing through the expansion / contraction device 100, the asphalt mixture is used. A part of 120 has no escape area in front of the expansion / contraction device 100 and swells, which adversely affects the finish (flatness) of the surface layer.

Therefore, at the end of the expansion / contraction device 100, the direction of the rolling load roller 110 is changed by approximately 90 degrees in the crossing direction of the road indicated by the arrow Y in FIG. 6, and the expansion / contraction device 100 is provided as shown in FIG. When the compaction road roller 110 is run with the compaction road roller 110 on the end, the swelling of a part 120 of the asphalt mixture shown in FIG. 7 is eliminated and the surface layer finish (flatness) is improved. Can be improved.

However, although it is known that it is effective to change the direction of the rolling road roller 110 by approximately 90 degrees with respect to the road direction and allow the road roller 110 to travel in the transverse direction at the end of the expansion / contraction device 100. For that purpose, it is necessary to secure a turning range for changing the direction of the rolling load roller 110. However, in order to change the direction of the rolling load roller 110 under the construction regulations, it is necessary to repeatedly turn the steering operation of the rolling load roller 110, which makes the turning operation difficult. In addition, there is a problem that the steering operation is performed many times, which may damage the pavement surface.

Therefore, we provide a compaction load roller with a structure that can shorten the work time and improve the finish (flatness) of the surface layer by making it possible to easily switch the required orientation in a small space. A technical problem to be solved arises in order to solve the problem, and an object of the present invention is to solve this problem.

The present invention has been proposed in order to achieve the above object, and the invention according to claim 1 is a compaction road roller for compacting a road surface on which an asphalt mixture or the like is spread, and the road surface is described. Provided is a rolling compaction road roller including a rolling compaction road roller main body traveling on the road surface and a vehicle body elevating device for lifting the rolling compaction road roller main body from the road surface so as to be able to turn substantially parallel to the road surface.

According to this configuration, for example, when it is necessary to change the direction of the compaction load roller body, when the compaction load roller body is slightly lifted from the road surface by the force of the vehicle body elevating device, the compaction load roller body and the road surface can be changed. A gap is created between them and the frictional force is removed. Then, in this state, if the rolling load roller body is swiveled substantially parallel to the road surface, for example, by human power, the direction of the rolling load roller body can be easily changed. Therefore, when the compaction road roller body that has moved along the traveling direction of the road is turned approximately 90 degrees along, for example, the expansion / contraction device, the direction is along the expansion / contraction device, that is, in the direction of crossing the road. After that, the rolling load roller main body can be lowered onto the road surface and run along the expansion / contraction device or the like. As a result, the direction of the rolling road roller can be easily changed by horizontally turning in a small space. Further, after turning and changing the direction, the vehicle body can be lowered onto the road surface under the control of the vehicle body elevating device, and the treading process can be continuously performed, so that the finish (flatness) of the surface layer can be improved.

The rolling load roller body can be swiveled horizontally by slightly lifting the body.

The invention according to claim 4 provides a rolling compaction load roller in the configuration according to claim 3, wherein the hydraulic device is arranged on both left and right sides of the rotation center axis of the turntable.

According to this configuration, when the rolling load roller body is lifted from the road surface and turned, the rolling load roller body is formed by a pair of hydraulic devices arranged on both the left and right sides of the rotation center axis of the turntable. Since it is lifted horizontally from both the left and right sides and swiveled, the swivel operation of the compaction load roller body can be performed in a stable state.

The invention according to claim 5 provides a rolling compaction load roller in the configuration according to claim 3, wherein the hydraulic pressure for operating the hydraulic actuator also serves as the hydraulic pressure for operating the rolling compaction load roller main body.

According to this configuration, since the hydraulic pressure for operating the hydraulic actuator and the hydraulic pressure for operating the rolling load roller body are used in combination, it is not necessary to separately prepare the hydraulic equipment on the hydraulic actuator side, and it can be realized at low cost. ..

The invention according to claim 6 has the configuration according to any one of claims 1 to 5, wherein the rolling load roller main body is provided with a rotatable front rolling roller wheel.

According to this configuration, the rolling load roller main body is provided with a front rolling load roller main body in which the front rolling roller wheel is rotatably provided and a rear rolling roller wheel in which the rear rolling roller wheel is rotatably provided to form a connecting portion. The so-called arculate type is formed by dividing the road roller into two parts, a rear side rolling load roller main body connected to the front side rolling load roller main body and the rear side rolling road roller main body. Therefore, since the connecting portion can cope with the movement (rolling) in the twisting direction, each rolling roller wheel can be run in a state of being constantly pressed against the road surface to improve the finish.

According to the invention, when the rolling road roller body that has moved along the traveling direction of the road is turned approximately 90 degrees along, for example, a telescopic device, the direction is changed in the direction of crossing the road. After that, the road roller can be run along the telescopic device or the like, so that the direction of the rolling road roller can be easily changed by horizontally turning in a small space. In addition, when turning, the rolling road roller can be smoothly lifted from the road surface by the force of the vehicle body lifting device, turned, and then lowered onto the road surface again to continue the compaction process.

In FIGS. 1 to 3, the vehicle body elevating device 12 is mounted on the landing plate 20 landed on the road surface 200 and on the substantially center of the landing plate 20 so as to be able to make a horizontal turn parallel to the landing plate 20. The turntable 30 and the center of gravity G of the rolling load roller body 11 are arranged on the rotation center axis O1 of the turntable 30, the lower end side is attached to the turntable 30, and the upper end side is attached to the rolling load roller body 11. It is equipped with a stretchable hydraulic means for expanding and contracting 40, which is attached.

The landing plate 20 is a horizontal disk-shaped plate, and a short cylindrical support shaft portion 21 projecting upward from the upper surface is provided in the center. A screw (not shown) for attaching the tightening nut 22 is engraved on the upper part of the outer circumference of the support shaft portion 21.

The turntable 30 is a plate having a through hole (not shown) for inserting and arranging the support shaft portion 21 of the landing plate 20 in the center. Further, on both the left and right sides of the turntable 30, expansion and contraction means mounting portions 31 projecting outward from the landing plate 20 are provided. Then, in the turntable 30, the support shaft portion 21 of the landing plate 20 is rotatably fitted and inserted into the central through hole, and the center of the through hole is substantially aligned with the rotation center axis O1 on the landing plate 20. It is stacked and arranged in. Further, a tightening nut 22 is screwed and fixed to the screw engraved on the upper part of the outer circumference of the support shaft portion 21 protruding from the upper surface side of the turntable 30 and integrated with the landing plate 20. Has been made. When the turntable 30 is stacked on the landing plate 20, a sliding member (not shown) is interposed between the turntable 30 and the landing plate 20. As a result, the turntable 30 is arranged in combination so as to be able to make a smooth horizontal turn with respect to the landing plate 20 by interposing the sliding member.

The expansion / contraction means 40 includes a pair of left and right hydraulic devices 41 arranged corresponding to the expansion / contraction means mounting portions 31 of the turntable 30, and a connecting plate 43 that supports the pair of left and right hydraulic devices 41. are doing.

The connecting plate 43 is a plate fixedly attached to the rear portion of the front rolling load roller main body 11A via a pair of left and right brackets 44 in a vertically placed state substantially parallel to the rear portion.

The hydraulic pressure of the hydraulic actuator 41A can be operated by the operator operating a lever on the hydraulic circuit operation panel (not shown) by using the hydraulic pressure of the hydraulic circuit system (not shown) provided in the rolling load roller main body 11. .. Then, when the operator selects the vehicle body elevating device retracting operation, the rod 41B is accompanied by the landing plate 20 and the turntable 30 as shown in FIGS. 2 and 3 (a) and 3 (b). The position pulled upward, that is, most of the rod 41B is placed in the hydraulic actuator 41A. On the contrary, when the operator selects the vehicle body elevating device overhang operation, the rod 41B is a hydraulic actuator with the landing plate 20 and the turntable 30 as shown in FIGS. 3 (c) and 3 (d). Protruding from the inside of 41A, the landing plate 20 is pressed against the road surface 200, and the rolling load roller 10 can be lifted from the road surface 200. The amount of lifting the rolling load roller body 11 from the road surface 200 is such that the front rolling roller ring 13A and the rear rolling roller ring 13B are slightly separated from the surface of the road surface 200 and are between the road surface 200 during horizontal turning. Any amount that does not generate frictional force may be used. Further, the horizontal turn here is a case where the road surface 200 is substantially horizontal, and when the road surface 200 is inclined, it also includes turning substantially parallel to the road surface 200. The same applies hereinafter.

FIG. 4 is a diagram illustrating an operation of lifting the rolling load roller main body 11 provided with the vehicle body elevating device 12 from the road surface 200, and FIG. 5 is a diagram showing the rolling compaction road roller main body 11 lifted from the road surface 200 so as to be horizontally swiveled. It is a figure explaining the operation which changes the direction of a compaction load roller main body 11 by about 90 degrees. Therefore, the operation of lifting the compaction load roller main body 11 from the road surface 200 and further turning it horizontally to change it by about 90 degrees will be described below by adding FIGS. 5 and 6 to FIGS. 1 to 3.

First, when the compaction load roller 10 is performing normal compaction work, the hydraulic operation of the hydraulic actuator 41A is selected by the operator to retract the vehicle body elevating device, and the rod 41B is shown in FIGS. 2 and 3. As shown in (a), (b), and (a) and (b) of FIG. 4, the landing plate 20 and the turntable 30 are housed in the hydraulic actuator 41A together with the landing plate 20 and the turntable 30. 30 is placed in a state of being moved to a position where it is pulled upward. Therefore, in this state, the landing plate 20 and the turntable 30 are separated from the road surface 200, and the rolling operation of the rolling load roller 10 is not hindered. Then, in this state, the compaction road roller 10 can be traveled along a paved road, for example, to perform compaction work.

Then, when most of the rolling work of the paved road is completed, for example, when approaching a road bridge expansion / contraction device or the like and then wanting to change the direction of the rolling load roller 10 by approximately 90 degrees, the operator descends from the rolling load roller 10. , Select the body elevating device overhanging operation in the hydraulic operation work of the hydraulic actuator 41A. When the vehicle body lifting device overhang operation is selected, a pair with the landing plate 20 and the turntable 30 as shown in FIGS. 3 (c) and 3 (d) and 4 (c) and 4 (d). The rods 41B are each projected from the hydraulic actuator 41A of the above, and the landing plate 20 is pressed against the road surface 200, respectively, and the vehicle body elevating device 12 simultaneously uses the front side rolling load roller main body 11A and the rear side rolling load roller main body 11B. Lift from the road surface 200.

When the front rolling load roller main body 11A and the rear rolling load roller main body 11B are lifted from the road surface 200, the road surface 200 and the front rolling roller wheel 13A, and the road surface 200 and the rear rolling roller wheel 13B The frictional force between them disappears. Then, at the position (a) of FIG. 5, the operator views both the front rolling load roller main body 11A and the rear rolling load roller main body 11B with the support shaft portion 21 (rotation center axis O1) as a fulcrum. When pushed in the direction of the arrow shown in 5 (b), the entire rolling load roller 10 makes a horizontal turn in the clockwise direction. As a result, the rolling load roller 10 is switched in a direction parallel to, for example, the expansion / contraction device for a road bridge.

Further, when the direction of the rolling load roller 10 is changed by approximately 90 degrees, the operator switches the hydraulic operation of the hydraulic actuator 41A to the vehicle body elevating device retracting operation. Then, as shown in FIGS. 2 and 3 (a) and (b), and FIGS. 4 (a) and 4 (b), the rod 41B is accompanied by the landing plate 20 and the turntable 30 and is a hydraulic actuator. Stored in 41A, the front rolling roller ring 13A and the rear rolling roller ring 13B of the rolling load roller body 11 are in contact with the road surface 200, and the rolling load roller 10 is tightened in a direction crossing the road. Rolling work can be done while compacting and running.

Further, when the direction of the compaction load roller main body 11 is switched back to the original state by 90 degrees, the direction can be switched by going through the reverse procedure of the previous step. It should be noted that the switching procedure described in this embodiment is merely an example, and it goes without saying that other switching operations can be adopted depending on the angle at which the direction of the rolling load roller main body 11 is changed. .. That is, the direction of the rolling load roller 10 can be switched at any angle without being limited to approximately 90 degrees.

Therefore, according to the rolling load roller 10 according to the configuration of the present embodiment, when it is necessary to change the direction of the rolling load roller main body 11, the rolling compaction road roller main body 11 is moved from the road surface 200 by the force of the vehicle body elevating device 12. By lifting and removing the frictional force between the rolling load roller body 11 and the road surface 200, the rolling load roller body 11 can be turned horizontally to easily change the direction of the rolling load roller body 11. .. As a result, the rolling road roller body 11 that has moved along the traveling direction of the road is swiveled approximately 90 degrees so as to be along the expansion / contraction device, for example, along the expansion / contraction device, that is, in the direction of crossing the road. Since the direction can be changed to and then traveled along the expansion / contraction device or the like, the direction of the rolling road roller 10 can be easily changed by horizontally turning in a small space. Further, after the orientation is switched, the rolling compaction load roller 10 can be lowered onto the road surface 200 by operating the vehicle body elevating device 12, and the treading process can be continuously performed, so that the working time can be shortened and the surface layer on the road surface 200 can be reduced. The finish can be improved.

In this embodiment, an articulated type rolling load roller 10 in which the space between the front rolling load roller main body 11A and the rear rolling load roller main body 11B is bent in the middle has been described as an example, but the present invention has been described. It is not limited to the articulated type rolling load roller, but is also applicable to, for example, a rigid frame type rolling load roller that does not break between the front side rolling load roller body and the rear side rolling load roller body. It can be done.

Further, the present invention can be modified in various ways as long as it does not deviate from the spirit of the present invention, and it is natural that the present invention extends to the modified ones.
