[0002] The dredging and rescue equipment currently used in the field of emergency equipment has the following characteristics:

[0003] 1. The equipment has a single function and is complex to operate. Some are used for emergency delivery on water, some use multiple pontoons in combination on water, and some temporarily carry operating equipment on existing hulls.

[0004] 2. Secondly, in order to ensure the stability of these equipment during water operations, larger ships are usually selected or auxiliary facilities are temporarily built.

[0005] 3. Most of these devices do not have the ability to travel on land. They must be transported to the destination by land vehicles and then put into the water with the help of lifting machinery and auxiliary facilities. They are inconvenient to use and reduce the efficiency of emergency rescue.

[0006] 4. In order to ensure that the rescue equipment can be launched into the water smoothly, the ground requirements for the launch channel and auxiliary facilities are relatively high. A large number of engineering machinery are needed to pave the road first to ensure that the rescue equipment can enter the water normally.

[0007] Considering that there are many types of emergency rescue equipment, each piece of equipment has its own power and can travel on land and water, the R&D and manufacturing costs are relatively high. Utility Model Content

[0008] Based on the cost and the above-mentioned emergency equipment situation, in order to change the current status of equipment in the field of dredging emergency equipment, the main purpose of the utility model is to provide a semi-hanging amphibious rescue pontoon, which can be quickly connected and disconnected from a tractor, and has the transportation and towing function of conventional roads.

Then the front support arm retraction oil cylinder and the pile-turning oil cylinder are driven to operate so that the front support arm and the positioning pile fall to the bottom of the operating area, thereby ensuring the stability of the front end of the pontoon during underwater operations.

[0025] 6. The front support arm and the lifting axle described in the present invention can be used in combination for parking a semi-hook amphibious rescue pontoon on land, and for coupling the towing arm to a tractor.

[0026] 7. The ballast water tank of the utility model can adjust the balance posture of the semi-hanging amphibious rescue buoy in water by adding water to and draining water from the ballast water tank.

[0027] 8. After the semi-hook amphibious rescue buoy of the present invention is towed to the water's edge by a tractor, the digging arm and the digging arm of the digging power system can cooperate to allow the tractor to reverse and put the semi-hook amphibious rescue buoy into the water.

When the engine 13 is started, it generates mechanical energy by burning the diesel in the diesel tank 17. Once started, the engine 13 drives its own electric motor to rotate and generate electricity. Part of the generated electricity is stored in a battery 15 to power electrical appliances when the vehicle is parked and the next time it starts, and the remaining part is used to power the vehicle's control system and hydraulic workstation 16.

[0060] Example 2:

[0061] A method for using a semi-hung amphibious rescue buoyancy tank comprises the following steps:

[0062] Step 1, preparation for towing the semi-hook amphibious rescue pontoon:

[0063] When rescue is needed, the lifting axle 2 is first lowered, so that the entire semi-hanging amphibious rescue pontoon is supported on the ground by the lifting axle 2, and the front support arm 5 and the positioning pile 8 are recovered;

[0064] Step 2: Towing connection of the semi-hook amphibious rescue buoy:

[0065] Connect the traction arm 19 to the universal tractor trailer via the traction pin 19-1;

[0066] Step 3: Shipping of the semi-hook amphibious rescue pontoon:

[0067] After the connection is completed, the entire semi-trailer amphibious rescue pontoon is moved and transported to the location where rescue is required by a tractor;

[0068] Step 4: Launching the semi-hung amphibious rescue pontoon:

[0069] After the semi-trailer amphibious rescue pontoon is towed to the water's edge by the tractor, the tractor reverses the tractor to lower the semi-trailer amphibious rescue pontoon into the water and disconnects it from the tractor.

[0070] Step 5: Adjust the water posture of the semi-hung amphibious rescue pontoon:

[0071] After the semi-hook amphibious rescue buoy enters the water, the balance posture of the semi-hook amphibious rescue buoy in the water is adjusted by adding water to or draining water from the ballast water tank 18 according to the entering posture;

[0072] Step 6: Driving the semi-hook amphibious rescue pontoon on water:

[0073] When the semi-hanging amphibious rescue pontoon is in the water-traveling state, the hydraulic workstation 16 controls the lifting axle 2 to rise, hiding the axle inside the pontoon, thereby reducing the resistance of the semi-hanging amphibious rescue pontoon on the water. Then, the propulsion device 12 drives the semi-hanging amphibious rescue pontoon to travel on the water to the operation area.

[0074] Step 7, preparation for the semi-hook amphibious rescue pontoon water excavation operation:

[0075] When it is necessary to carry out water excavation operations, the front arm 5 is driven to extend around the arm seat 4 by the hydraulic workstation 16, and the front arm extension cylinder 6 and the pile-drop cylinder 9 are operated to deploy the front arm 5 to both sides of the pontoon 1, and the positioning pile 8 is placed toward the tail end to a vertical state, and then the front arm retraction cylinder 7 and the positioning pile lifting cylinder 10 are driven to operate to make the front arm 5 and the positioning pile 8 fall to the bottom of the working area, thereby ensuring the stability of the front end of the pontoon during underwater operations;

[0076] Step 8: Excavation operation on the semi-hook amphibious rescue pontoon:

[0077] During the water excavation operation, the hydraulic workstation 16 drives the rotary hydraulic motor 20 to rotate the excavation power system 3 horizontally on the upper surface of the front end of the pontoon 1, and rotates the excavation power system 3 to the working position; the hydraulic workstation 16 drives the boom pitch cylinder 3-4, the arm pitch cylinder 3-6, and the bucket tilt cylinder 3-8 to operate, so as to achieve the different working postures of the boom 3-3, the arm 3-5 and the bucket 3-7, thereby completing the excavation operation;

[0078] Step 9, recovery of the semi-hung amphibious rescue pontoon:

[0079] After the water excavation operation is completed, the propulsion device 12 is used to drive the semi-hook amphibious rescue pontoon to the shore on the water, and then the towing arm 19 is connected to the general tractor through the towing pin 19-1, and the lifting axle 2 is lowered synchronously, and the tractor is started to drag the entire semi-hook amphibious rescue pontoon for transportation and recovery.
