Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a high pressure washing vehicle.

0002

[Conventional technology]

Conventionally, a rotating body is rotatably disposed at the rear of the vehicle body, and a hydraulic motor is mounted on the rotating body. A hose reel that is driven to rotate is mounted, and the hose reel has a tip. A high-pressure washing vehicle is provided in which a hose equipped with a washing nozzle is wound around the hose. and For example, in a high-pressure washing vehicle equipped with a self-propelled washing nozzle, this washing nozzle is connected to a sewer pipe. After placing the cleaning nozzle in the The cleaning nozzle is advanced in the sewer pipe by feeding the hose from the srill into the sewer pipe. Once the cleaning nozzle has advanced to the specified position, forcefully wind up the hose and begin cleaning. The cleaning nozzle is moved back to its original position against the propulsion force, thereby cleaning sewer pipes, etc. was going on.

0003

[Problem that the idea aims to solve]

However, with the above-mentioned conventional method, the There is a problem that cleaning with a cleaning nozzle cannot deal with heavily soiled areas. Ta.

0004

[Means to solve the problem]

The high-pressure washing vehicle of this invention has a hydraulic motor mounted on a revolving body that is rotatably installed at the rear of the vehicle body. In a high-pressure washing vehicle equipped with a hose reel that is rotationally driven by a -A hose with a removable cleaning nozzle at the tip is wound around the reel, and on the other hand, On the rotating body, there is a second hose tree around which a hose having a cleaning gun is wound at the tip. This means that there is a rule.

[0005]

[Effect] A second hose reel wound with a hose having a cleaning gun at the tip is installed on the revolving body. As a result, areas that are locally heavily contaminated, such as around sewage pipe manhole entrances, should be removed. The contractor pulls out the hose from this second hose reel and cleans it with a cleaning gun. I do.

【Example】

An embodiment of the present invention will be described below with reference to the drawings.

[0007] FIGS. 1 and 2 schematically show the overall structure of a high-pressure washing vehicle according to the present invention.

[0008] A tank 3 for storing cleaning water is mounted on a vehicle body 2 of a high-pressure cleaning vehicle 1. car At the rear of the body 2, there is a turntable (swivel body) that can be rotated by a drive device (not shown). 5 is mounted on the turntable 5, and a large hose reel (ho - reel) 10 and a small hose reel (second hose reel) 20 A reel is placed.

[0009] As shown in FIG. 3, the large hose reel 10 is rotated in forward and reverse directions by a hydraulic motor 11. The hose wound around this large hose reel 10 is The thread 12 is fed out or wound up. There is a washing machine at the end of hose 12. A cleaning nozzle 13 is detachably provided.

0010 The small hose reel 20 is a manual type, and the handle 21 shown in FIG. 3 is rotated. By doing so, the hose 22 wound around this small hose reel 20 can also be fed out. Or, it can be rolled up. A cleaning gun 23 is detachable from the end of the hose 22. It is currently set up.

[0011] The turntable 5 can rotate approximately 180 degrees (see the two-dot chain line in FIG. 2). The large hose reel 10 and the small hose on the turntable 5 are configured as follows. Adjust the feeding and winding directions of the hoses 12 and 22 on the reel 20 according to the work situation. You can change it as you see fit. In addition, the turntable 5 is connected to a securing means (not shown). It is secured in a more appropriate turning position.

0012 FIG. 3 shows the power and piping system of the high pressure washing vehicle of the present invention.

[0013] In FIG. 3, 31 is a hydraulic pump, and the hydraulic pump 31 is connected to a drive shaft 32. , and is driven by an engine 35 connected via a PTO 33. hydraulic pump 3 The discharge side of 1 rotates the aforementioned large hose reel 10 via a directional control valve 36. The hydraulic motor 11 is connected to the hydraulic motor 11 that is connected to the The rotation direction of the motor 11 is controlled. 37 is a flow control valve, and this flow control valve 37 The rotational drive speed of the hydraulic motor 11, that is, the hose 1 by the large hose reel 10 Controls the feeding/winding speed of step 2. 38 is an oil reservoir.

[0014] 40 is a water pump, and the water pump 40 includes a pulley/V belt 41 and the drive system. It is driven by an engine 35 connected via a shaft 32 and a PTO 33. water The pump 40 has its suction side connected to the bottom of the tank 3, and its discharge side connected to the large hole. - communicated with each hose 12, 22 via reel 10 and small hose reel 20 There is.

[0015] Next, the use of the high-pressure washing vehicle configured as described above will be briefly explained.

[0016] For example, a sewer pipe A as shown in FIG. 4 is cleaned using a self-propelled cleaning nozzle 13. In this case, first rotate the turntable 5 to connect the hose 12 of the large hose reel 10. Direct the large hose reel 10 toward the manhole B side so that it can be easily fed to the sewer pipe A, and The rotation of the turntable 5 is secured by an appropriate securing member.

[0017] Then, the cleaning nozzle 13 is placed in the sewer pipe A, and then the water pump 40 is activated. At the same time, high-pressure water is supplied to the cleaning nozzle 13 to give a driving force to the cleaning nozzle 13. Along with this, the large hose reel 10 is rotated by the hydraulic motor 11 and the hose 12 is rotated. The cleaning nozzle 13 is advanced within the sewer pipe A by feeding it out into the sewer pipe A.

[0018] Next, when the cleaning nozzle 13 advances to a predetermined position, it is time to move the large hose reel 10. The rotation is reversed and the hose 12 is forcibly wound against the propulsive force from the cleaning nozzle 13. By removing the cleaning nozzle 13, the cleaning nozzle 13 is moved back to its original position and the sewer pipe A is cleaned. cormorant.

[0019] Also, be sure to remove any locally contaminated areas such as around the entrance to manhole B of sewer pipe A. A contractor appropriately pulls out the hose 22 from the small hose reel 20 and runs it through the cleaning gun 23. Perform cleaning.

[0020] Such work is performed sequentially from the upstream side of the sewer pipe A.

[0021]

[Effect of the idea]

As described above, according to the present invention, the cleaning gun is detachably attached to the tip of the hose. By installing the second hose reel on the revolving body, the sewage manhole Easily clean locally heavily soiled areas such as around the entrance of the room, improving work efficiency. can be achieved.
