Description

  The present invention relates to a rolling machine for compacting a road surface.

  When rolling a road or the like using a rolling machine, particularly a tire roller equipped with a tire drive wheel, a liquid such as water or oil is applied to the tire using a spraying device to prevent the mixture from adhering to the tire. It is over. The spraying device includes a tank, a spraying pipe, and a spraying pipe connecting these. In the case of water, when the water is cold, the water in the sprinkling pipe freezes to prevent the sprinkler from being destroyed and the delay in resuming work due to freezing. ing. In order to ensure such drainage, it is known to send pressurized air into the sprinkling pipe (see, for example, Patent Document 1).

Japanese Patent No. 2873166

  However, when a tire is attached to the vehicle body via a rotating shaft like a tire roller (rolling machine), the spray pipe also rotates together with the tire, so the spray pipe also follows this. There is a need. For this reason, the sprinkling pipe is often formed using a flexible pipe such as a hose, but a certain amount of deflection is required to follow the rotation of the tire. Depending on how the sprinkling pipes are handled, liquid may accumulate in this bent portion, and water may freeze when the liquid is water. In order to prevent such a phenomenon, there is an example in which pressurized air is supplied into the sprinkling pipe to try to drain water, but equipment for that purpose is required, which is expensive.

  The present invention has been made in consideration of the above-described conventional technique, and an object of the present invention is to provide a compacting machine that can discharge liquid reliably only by releasing a spray pipe with a simple structure.

  To achieve the above object, according to the present invention, a plurality of tires arranged in a line in the left-right direction of the vehicle body and connected to each other, a yoke integrally connected to the plurality of tires, and a vehicle body fixed to the yoke and fixed to the vehicle body A rotating shaft that extends in the vertical direction of the plurality, a spray pipe that extends along the width direction of the plurality of tires, a spray pipe that has one end connected to the spray pipe and through which the liquid flows, and the spray liquid In the compaction machine including a tank connected to the other end of the pipe and disposed in the vehicle body, the spray pipe intersects at least the axis of the rotary shaft body and is on the upper surface of the rotary shaft body. A rolling machine is provided, which is fixed and extends downward in the vertical direction along the axis of the rotating shaft.

  Preferably, the rotating shaft body includes a columnar shaft member and a disk member having a diameter larger than that of the shaft member fixed to the upper side of the shaft member, and the spray pipe includes the disk member. It penetrates and extends along the shaft member, and further extends forward or rearward and downward of the vehicle body and is connected to the spray pipe.

Preferably, the spray pipe is fixed to the shaft member.
Preferably, the sprinkling pipe is composed of a sprinkling pipe through which water flows and an oil sprinkling pipe through which oil flows, and the sprinkling pipe is formed from a sprinkling pipe through which the water flows and a sprinkling pipe through which the oil flows. Become.

  According to the present invention, the sprinkling pipe intersects with the axis of the rotating shaft body and is fixed to the upper surface of the rotating shaft body, and further extends downward along the axis of the rotating shaft body. The bent part of the liquid piping is eliminated, and the part where the liquid (water or oil) accumulates can be eliminated. In this way, when the liquid is water, water can be prevented from freezing only by handling the spraying pipe, so it is possible to drain the water by simply opening the spraying pipe with a simple structure without the need for new equipment. It can be done reliably. As a result, it is possible to prevent damage to the sprinkling pipe and to prevent stagnation of the rolling work. Further, even when the tire is rotated in the left-right direction of the vehicle body together with the yoke, the spray pipe does not bend. Therefore, no matter what position the tire is turned to, there is no influence on the liquid discharge reliability.

It is a side view of the rolling machine which concerns on this invention. It is the schematic when a vehicle body is seen from front part upper part. It is the schematic when a vehicle body is seen from front part lower part. It is the schematic which shows the state which the tire rotated to the right side. It is the schematic which shows the state which the tire rotated to the left side.

Hereinafter, a rolling machine according to the present invention will be described with reference to the drawings.
Referring to FIG. 1, a tire roller 1, which is a kind of a rolling machine, includes a plurality of tires 4 that form wheels before and after rolling a pavement surface, and a vehicle body 6 that travels with the tires 4. A canopy-type driver's seat 8 is provided in the upper center of the vehicle body 6. The driver's seat 8 can be lifted and lowered using a step 10 disposed on the side of the vehicle body 6. An operation stand 12 is disposed in front of the driver seat 8. The operation stand 12 is provided with a handle 14 and the like for steering the vehicle body 6.

  Various tanks are provided inside the vehicle body 6. For example, a tank 2 storing various liquids is provided at the front, and a fuel tank (not shown) and a hydraulic oil tank (not shown) are provided at the rear. An oil supply port 20 for supplying fuel into the fuel tank is disposed at the upper part of the vehicle body 6. Further, an engine room (not shown) is further provided at the front portion of the vehicle body 6, and this engine room is covered with an engine cover cover 22 that can be opened and closed. An engine (not shown) and a hydraulic pump (not shown) are arranged in the engine room. The hydraulic pump is driven by an engine and supplies hydraulic oil stored in a hydraulic oil tank toward a traveling motor that drives the tire 4 and a hydraulic motor that will be described later. The tire 4 is driven by driving the axle from a hydraulic motor via a propeller shaft (not shown). In this example, only the rear wheels are driven and the front wheels are not driven.

  On the other hand, a plurality of tires 4 are arranged in a line in the left-right direction of the vehicle body 6, and are connected to each other by the rotating shaft 3. The tire 4 rotates around the rotation shaft 3. The rotating shaft 3 passes through a frame-shaped axle frame 5 disposed between the tires 4. Therefore, the tire 4 and the axle frame 5 are integrally connected as an assembly via the rotating shaft 3. A yoke 7 is arranged on the upper side of the tire 4 so as to cover the tire 4. The yoke 7 is connected to the front and rear sides of the axle frame 5 using pins 9. Therefore, the axle frame 5 is swingably attached to the yoke 7, and the yoke 7 and the tire 4 are integrally configured as an assembly via the axle frame 5.

  As shown in FIGS. 2 and 3, the vehicle body 6 is provided with a spraying device for supplying liquid to the tire 4. The spraying device includes the tank 2, the spraying pipe 11, and the spraying pipe 13 described above. The spray pipe 13 extends along the width direction of the plurality of tires 4 and is fixed to the yoke 7 via a bracket 15. In addition, in the figure, the example provided with the two sprinkling pipes 13 (sprinkling pipe 13a, sprinkling pipe 13b) is shown. Accordingly, an example in which two sprinkling pipes 11 are provided corresponding to this (sprinkling pipe 11a, sprinkling pipe 11b) is shown. Water circulates through the watering pipe 13a and the watering pipe 11a, and oil flows through the oiling pipe 13b and the oiling pipe 11b. The spray pipe 13 has a pipe shape, and a nozzle 23 is formed at a predetermined location. Liquid flows out from a hole provided at the tip of the nozzle 23 and is supplied to the tire 4. As described above, two spray pipes 13 are prepared and sprayed with water and oil to prevent dust from rising by spraying water and cooling the pavement surface, and asphalt adheres to tire 4 by spraying oil. Can be prevented.

  One end of the spray pipe 11 is connected to the spray pipe 13. In the example of the figure, a watering pipe 11a is connected to the watering pipe 13a, and an oiling pipe 11b is connected to the oiling pipe 13b. The liquid flowing through the spray pipe 11 is supplied to the spray pipe 13. The other end of the spray pipe 11 is connected to the tank 2 described above. When two sprinkling pipes 11 of water and oil are prepared, the tank 2 is prepared for each liquid. The liquid in the tank 2 is supplied to the spray pipe 13 through the spray pipe 11. Such liquid circulation is appropriately performed using a pump or the like. Specifically, the liquid is sucked up from the tank 2 using a pump and sent to the nozzle on the front wheel or rear wheel side through the distributor through the filter.

  On the other hand, on the upper side of the yoke 7, a rotating shaft body 16 extends and is fixed in the vertical direction of the vehicle body 6. The rotating shaft body 16 is formed of a columnar shaft member 17 and a trapezoidal disk member 18 that is trapezoidal than the shaft member 17. The disk member 18 is fixed to the upper side of the shaft member 17. The rotary shaft 16 rotates by turning the handle 14 described above. As the rotary shaft 16 rotates, the yoke 7 horizontally rotates in the left-right direction, and the tire 4 also rotates in the left-right direction via the axle frame 5 together with this.

  Here, the spray pipe 11 is fixed via a bracket 19 in the vicinity of the shaft center of the shaft member 17 on the upper surface of the rotating shaft body 16 (more specifically, the upper surface of the disk member 18). Specifically, the water sprinkling pipe 11 a and the oil sprinkling pipe 11 b are fixed together by the bracket 19. Furthermore, the spray pipe 11 is fixed so as to be in a positional relationship intersecting with the axis of the rotary shaft body 16 (more specifically, the axis of the shaft member 17). That is, the sprinkling pipe 11 is disposed so as to pass through the upper center of the disk member 18. The spray pipe 11 is disposed so as to extend downward in the vertical direction along the axis of the rotary shaft body 16. Specifically, the sprinkling pipe 11 passing through the upper center of the disk member 18 penetrates the disk member 18 in the vertical direction and extends along the surface of the shaft member 17 to the lower side in the axial direction of the shaft member 17. . And it extends in the forward direction and downward direction of the vehicle body 6 as it is, and is connected to the spray pipe 13. When the undercarriage structure (tie, 4, axle frame 5, yoke 7) and the spray pipe 13 provided in a steerable manner are arranged behind the tire 4, the same as in the above-described embodiment. After extending along the shaft member 17, the vehicle body 6 extends backward and is connected downward.

  In this way, the sprinkling pipe 11 (water sprinkling pipe 11a, oil sprinkling pipe 11b) is fixed to the upper surface of the rotating shaft body 16 so as to intersect the axis of the rotating shaft body 16, and further along the axis of the rotating shaft body 16. Therefore, the bent portion of the sprinkling pipe 11 is eliminated and the portion where water accumulates can be eliminated. In particular, by allowing the sprinkling pipe 11 to pass through the upper center of the disk member 18 and hang down along the shaft member 17 as it is, it is possible to prevent the sprinkling pipe 11 from being bent in the vertical direction as much as possible. There is no deflection in the direction. This is because the spraying pipe 11 is fixed at such a position to follow the steering operation, and the soaking structure 11 (the tire 4, the axle frame 5 and the yoke 7) is integrated with the spraying pipe 11. This is because the bending of the spray pipe 11 can be suppressed. In this way, water can be prevented from freezing only by handling the spraying pipe 11, so that it is possible to reliably drain water by simply releasing the spraying pipe 11 with a simple structure without requiring a new device or the like. become able to. As a result, it is possible to prevent damage to the sprinkling pipe 11 and to prevent stagnation of the rolling work. Note that if the spray pipe 11 is fixed to the shaft member 17 via the bracket 21, the deflection of the spray pipe 11 can be further suppressed.

  Further, as shown in FIGS. 4 and 5, the sprinkling pipe 11 passes through the upper center of the disk member 18 and hangs down along the shaft member 17 as it is even if the tire 4 rotates to the right. Even if it rotates to the left side, it is not necessary to provide the extra sprinkling pipe 11 so as to follow it. Therefore, even if the tire 4 together with the yoke 7 is rotated in the left-right direction of the vehicle body 6, the spray pipe 11 does not bend. That is, no matter what position the tire 4 is rotated to, the reliability of drainage is not affected.
