Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to emergency drainage at the time of water disaster,
The present invention relates to a drainage pump vehicle used for drainage of civil engineering temporary construction work or water supply and drainage for agriculture.

[0002]

2. Description of the Related Art Conventionally, as a drainage pump vehicle used for emergency drainage in the event of a water disaster, temporary construction work drainage, agricultural water supply / drainage, etc., a crane used for loading and unloading on-board equipment such as pumps. , A plurality of drainage pumps (submersible pumps) and a drainage pump with floats, a private power generator that supplies power to the drive sources (motors) of these drainage pumps, their operation panel, and drainage ports of each drainage pump. The drain hose to be connected, the cavern tire cable that electrically connects the drive source of each drain pump and the operation panel of the private power generator, the main floodlight for night work, the auxiliary floodlight for spot lighting, and power to this auxiliary floodlight. There is something that is equipped with equipment such as a portable power generator. According to this type of drainage pump vehicle, if it reaches the water level of the drainage or water supply / drainage site by self-propelled, after connecting the drainage hose and the connection of the tire cable, the drainage pump is driven by the crane. Water is drained by operating the drain pump by supplying electric power to the drive source of the drain pump by operating the private power generator.

By the way, in the conventional drainage pump vehicle,
If the ground at the drainage or water supply / drainage site and its surroundings is hard, the drainage pump car can be driven to the water's edge, but if the ground is soft, it cannot be driven to the water's edge. Therefore, the stop position of the drainage pump car is restricted to a place relatively remote from the water's edge. For that purpose, various operations such as the work of transporting the drainage pump with a float that has been unloaded from the cargo bed by the crane to the water's edge, the work of laying the drainage pump from the water's edge to the water, and the work of connecting and connecting the tire tire cable are performed manually. There must be. In other words, the work of transporting the drainage pump unloaded from the crane by the crane to the waterside by the hand cart, the construction of the inclined guideboard at the waterside, and the work of laying the drainage pump underwater using the constructed inclined guideboard. Many tasks must be performed by many workers.
Moreover, since these operations are extremely troublesome and difficult, the workability is poor and the quick start of drainage after reaching the drainage or water supply / drainage site is hindered. Further, since a private power generator for operating the drainage pump, a control panel, etc. are required, there is a disadvantage in that the equipment becomes large in size and economically disadvantageous.

Therefore, the applicant of the present invention has filed Japanese Patent Application No. 4-33.
In No. 269, even if the drainage or water supply / drainage site and the ground around it are weak, the amphibious vehicle is allowed to self-propelled to the water's edge, and the amphibious vehicle is lowered from the carrier's carrier platform to the water's edge. Operation, launching the amphibious vehicle from the water's edge and moving it to the water depth area where the drainage pump can operate, floating the amphibious vehicle in this water depth area, and then draining it, draining water after the drainage is completed A series of operations such as stopping the operation of the pump, returning the amphibious vehicle to the water's edge, and moving it from here to the transportation vehicle and placing it on the bed,
We proposed a drainage pump car that can be configured to be operated by remote control and improve workability.

However, in this type of drainage pump vehicle, for example, when the waterside is formed by a large step, the amphibious vehicle, that is, the drainage pump vehicle cannot enter the drainage area and drains water. There are difficulties that cannot be done.

[0006]

The problem to be solved is that when an amphibious vehicle cannot enter the drainage area,
The point is that it cannot be drained.

[0007]

According to the present invention, a water surface levitation child vehicle equipped with a boat-type sealed body is mounted on an engine-equipped parent vehicle capable of running on soft ground, and this child vehicle is provided with an external boat-type sealed body. A drainage pump for draining water is installed, and at least the drainage pump of the slave vehicle can be operated by using the engine as a drive source, so that the drainage can be performed even when the amphibious vehicle cannot enter the drainage area. Achieved the purpose of enabling.

[0008]

According to the present invention, the child vehicle can be moved to the waterside with the child vehicle mounted on the parent vehicle, and from this point, the child vehicle can be launched by self-propelled or downhill guided by the step board. The water can be easily drained even at the impenetrable water of the amphibious vehicle described in the comparative example.

Each of the suction ports A and 5B penetrates the bottom of the boat-shaped hermetically sealed body 2A in a watertight manner and opens on the lower side of the bottom. Then, by switching the switching valve 7A1 and the electromagnetic or electric switching valve 7B1 on the side of the slave vehicle 2, one of the hydraulic pumps 6A via the connecting hydraulic hoses 9A, 9B is used to drive the slave vehicle. 8B1 or the drain pump driving motor 10A is supplied with pressure oil to operate, and the switching valve 7A2 and the electromagnetic or electric switching valve 7 on the slave vehicle 2 side are operated.
By switching operation of B2, the other vehicle hydraulic motor 6B and the drain pump driving motor 10B are driven from the other hydraulic pump 6B via the connecting hydraulic hoses 9C and 9D.
It is designed to operate by supplying pressure oil to. In addition,
The switching valves 7B1 and 7B2 on the child vehicle 2 side are also the switching valves 7A.
As with 1, 7A2, they are controlled by a remote controller. Reference numeral 11 indicates a winch, which is mounted on the parent vehicle 1.

Next, a description will be given of the work procedure at the site where the waterside has a large step. The parent vehicle 1 having the floating surface child vehicle 2 is loaded on the bed of a transportation vehicle (not shown) such as a truck and transported to the vicinity of the drainage or water supply / drainage site. When the vehicle nears the site, the parent vehicle 1 is self-propelled by remote control and, for example, a guide member such as an inclined guide table is used as a guide to descend from the loading platform of the transport vehicle, and from here to the waterside shown in FIG. Run 1 self-propelled. Here, a drain hose (not shown) is connected to the discharge ports of the drain pumps 5A and 5B mounted on the child vehicle 2, and a hydraulic path on the child vehicle 2 side and a hydraulic path on the parent vehicle 1 side are connected. The hydraulic hoses 9A, 9B, 9C and 9D are connected to each other. Subsequently, the switching valves 7A1 and 7A2 on the parent vehicle 1 side and the switching valve 7B on the child vehicle 2 side are remotely controlled.
1, 7B2 is switched and the engine 4 is started to start the slave vehicle running motors 8B1 and 8B2.
By rotating the crawlers 2B and 2C, the child vehicle 2 is allowed to self-propell, and the step board 12 installed from the parent vehicle 1 toward the water surface is guided down to the water surface. When the inclination angle of the step board 12 is large, the wire of the winch 11 is connected to the child vehicle 2 to prevent the child vehicle 2 from slipping off while the step board 12 is being slid.
You can simply descent to the surface of the water as a guide.

The launched child vehicle 2 is a boat-shaped closed body 22.
It floats on the water surface by the buoyancy of A. Switching valve 7 in this state
When B1 and 7B2 are switched, the child vehicle 2 stops at the water surface, the drain pump driving motors 10A and 10B are activated, and the drain pumps 5A and 5B are operated to start draining. Drainage pump 5
As the water level drops due to A and 5B operation,
The control device described above transmits a rotation speed control radio signal of the engine 4 to reduce the rotation speed of the engine 4, and the hydraulic pumps 6A, 6B and the drain pump driving motors 10A, 10 are driven.
The rotation speed of B may be reduced, and the drainage pumps 5A and 5B may be operated at a rotation speed corresponding to the fluctuating water level for draining.
That is, the drainage pumps 5A and 5B can be operated at a low speed according to the decrease in the water level.

After the drainage is completed, the switching valves 7B1 and 7B2 are switched to stop the operation of the drainage pumps 5A and 5B, start the slave vehicle traveling motors 8B1 and 8B2, and set the crawlers 2B and 2B.
Rotate C. When the crawlers 2B and 2C rotate, crawler protrusions (not shown) provided on the crawlers 2B and 2C rotate, and the slave vehicle 2 moves forward or backward in a floating state according to the rotation direction. You can get thrust. In addition, steering for turning the slave vehicle 2 can be performed by changing the rotational speeds of the left and right crawlers 2B, 2C. Therefore, after the drainage is completed, the child vehicle 2 can be moved to the step board 12 in a floating state, and then the step board 12 can be climbed up to guide and returned onto the parent vehicle 1. If the inclination angle of the step board 12 is large,
Connect the wire of winch 11 to child vehicle 2 and winch 1
It is sufficient to return to the parent vehicle 1 while pulling with 1. When returning to the parent vehicle 1, the drain hose connected to the discharge ports of the drain pumps 5A and 5B and the hydraulic hose 9 connecting the hydraulic path on the child vehicle 2 side and the hydraulic path on the parent vehicle 1 side
Remove A, 9B, 9C and 9D to prepare for the next drainage or water supply / drainage.

As described above, since the sub vehicle 2 can be separated from the main vehicle 1 to perform drainage or water supply / drainage, since the waterside is formed by a large step, the Japanese Patent Application No.
The drainage pump vehicle described in No. 33269 can easily drain water even at a site where entry into the drainage area is impossible.

On the other hand, at the site where the water's edge is formed with a relatively gentle slope, as shown in FIG.
Without using 1, the child vehicle 2 can be launched and drained by using the walk board 12 as a guide, and after the drainage is completed, the walk board 12 can be returned to the parent vehicle 1 as a guide.

In the above embodiment, the boat-shaped closed body 2A,
