Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle for a rescue boat. Background Technology

[0002] Rescue boats are suitable for complex waterways such as rivers, lakes, rapids, and floods, and can be used to search for missing persons, rescue those who have fallen into the water, and transport supplies. Rescue boats can quickly transfer trapped people and supplies, and open up lifelines. In addition, rescue boats can cooperate with fire brigades to carry out tasks such as waterborne firefighting and hazardous chemical disposal, and can also be used for public security maritime patrols, law enforcement, and counter-terrorism and emergency response.

[0003] Rescue boats can only travel on water; when not in water, they require a vehicle for transport. Common rescue boat carriers, when lifting rescue boats, typically have an inner bottom that can only accommodate a single type of rescue boat. Since different rescue boat models have different bottom structures, using a single carrier cannot meet the load-bearing requirements of different rescue boat models, resulting in a limited applicability and poor practicality. Utility Model Content

[0004] The purpose of this application is to provide a rescue boat carrier to solve the problem that the common rescue boat carriers mentioned in the background art can only be adapted to a single model of rescue boat when lifting rescue boats. However, the bottom structure of different models of rescue boats is different. Therefore, when using a single carrier, it is impossible to meet the carrying requirements of different models of rescue boats, resulting in a small range of applicability and poor practicality of the single carrier.

[0005] To achieve the above objectives, this application provides the following technical solution: a rescue boat carrier, comprising a frame, a connecting seat fixed to the front side of the frame, two rollers rotatably connected to the left and right sides of the frame via bearings, an oil tank and several hydraulic cylinders fixed to the bottom inner side of the frame, the hydraulic cylinders being arranged linearly from front to back, a spring fixed to the top of each hydraulic cylinder, a first U-shaped seat fixed to the top of the spring, a roller rotatably connected between the opposing inner walls of the first U-shaped seat via bearings, a guide rod fixed to the bottom of the first U-shaped seat, the spring sleeved on the outside of the guide rod, a piston fixed to the bottom end of the guide rod, and the piston and the inner... The oil tank is equipped with a sliding fit. A return pipe is fixedly connected to the oil storage tank, and a transfer pipe is fixedly connected to the other end of the return pipe. A delivery pipe is fixedly connected between the transfer pipe and the cylinder barrel. An oil pump is fixedly installed on the oil storage tank. The oil inlet of the oil pump is connected to the oil storage tank, and an oil delivery pipe is fixedly connected between the oil outlet of the oil pump and the transfer pipe. Solenoid valves are installed on both the return pipe and the oil delivery pipe. A shifting assembly and two pressing assemblies are installed on the frame. A lifting assembly is installed on the shifting assembly. The shifting assembly is used to adjust the position of the lifting assembly. The lifting assembly is used to lift the rescue boat. The pressing assembly is used to clamp and fix the rescue boat on the roller.

[0006] Furthermore, a limit post is fixed to the bottom of the inner side of the cylinder, and a buffer sleeve is fixedly sleeved on the outside of the roller.

[0007] Furthermore, an oil replenishment pipe is fixedly connected to the oil storage tank, and a manual valve is installed on the oil replenishment pipe.

[0008] Furthermore, the pressing assembly includes a second U-shaped seat and two third U-shaped seats. The second U-shaped seat and one of the third U-shaped seats are fixedly mounted on the frame. A rotating rod is rotatably connected between the relative inner walls of the second U-shaped seat through a bearing. A pressure plate is fixed to the outer wall of the rotating rod. The other third U-shaped seat is fixedly mounted on the pressure plate. A sleeve is rotatably connected between the relative inner walls of the pressure plate through a pin. A hydraulic cylinder is fixedly installed between the two sleeves.

[0009] Furthermore, the transfer assembly includes two guide rails and a drive motor. The two guide rails and the drive motor are fixedly mounted on the frame. The guide rails are slidably fitted with sliding sleeves. Fixed plates are fixed on the sliding sleeves. A rack is fixed between the two fixed plates.

[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, several rollers are used to lift the rescue boat. The rescue boat relies on its own weight to squeeze the rollers and descend to different degrees. When the rollers move down, the piston will squeeze some of the hydraulic oil inside the cylinder into the oil tank. By opening and closing the solenoid valves on the return pipe and the oil supply pipe, the inflow and outflow of hydraulic oil inside the cylinder can be stopped after the rescue boat stops. With the help of the pressing component and the rollers, the rescue boat can be clamped and fixed. This can not only meet the load-bearing requirements of different types of rescue boats, but also make the lifting and carrying of the rescue boat more convenient.

[0013] In this invention, a drive motor drives a gear to rotate, which in turn pulls a rack to move. The rack, in turn, pulls a sliding sleeve to move with the help of a fixed plate. This causes the two sliding sleeves to move along two guide rails, which in turn supports the movement of the rack. The rack then drives the lifting assembly to move above the rescue boat, facilitating the lifting operation. Attached Figure Description

[0023] Working principle of this utility model: Fix the connecting seat 2 to the tractor and use the tractor to move the device. Before loading the rescue boat, move the device to the front of the rescue boat and start the drive motor 27 to drive the gear 28 to rotate. The gear 28 pulls the rack 26 to move to the rear of the device. The rack 26 pulls the sliding sleeve 23 along the guide rail 22 with the help of the fixing plate 25. The auxiliary wheel 24 helps the sliding sleeve 23 slide more smoothly along the guide rail 22. After the lifting assembly is moved directly above the rescue boat, stop the operation of the drive motor 27 and start the winch 30 to release the traction rope 31, so that the traction rope 31 drives the hook 34 to descend. Use the hook 34 to hook the rope or hook on the rescue boat. Then start the winch 30 to wind up the traction rope 31, so that the rescue boat is lifted off the ground. The drive motor 27 drives the gear 28 to rotate in the opposite direction. The gear 28 pulls the rack 26 back to the starting position, and the rescue boat is moved into the device. The winch 30 is activated again to lower the rescue boat, so that multiple rollers lift the rescue boat. The rescue boat squeezes the multiple rollers and descends in an orderly manner until the multiple rollers stop descending. When the rollers descend, the hydraulic oil in the cylinder 5 is squeezed out by the piston and finally flows into the oil tank 4 along the return pipe 10. The solenoid valve on the return pipe 10 is closed, and the hydraulic cylinder 21 is activated to push the pressure plate 19 to rotate around the rotating rod 18. After the multiple rollers lift the rescue boat, the pressure plate 19 and the rollers can clamp and fix the rescue boat. After the rescue boat is fixed, the device and the rescue boat can be moved to a different position by a tractor.
