[0001] This utility model belongs to the field of automotive repair tools technology, specifically relating to a multi-point hydraulic lift. Background Technology

[0002] Considering the situation where vehicles are severely damaged during field operations and long-distance transportation, and emergency measures are ineffective, the lack of equipment to lift the vehicles for repair workers would seriously affect vehicle performance repair and mission progress. Therefore, we researched this multi-point hydraulic lifting system for field use. Utility Model Content

[0003] The purpose of this invention is to provide a multi-point hydraulic lift that can facilitate the lifting of the entire vehicle for maintenance under field conditions.

[0004] The specific technical solution adopted by this utility model is as follows: A multi-point hydraulic lift includes a hydraulic oil tank. An electric oil pump, a manual oil pump, and a distribution pipe are fixedly installed at the upper end of the hydraulic oil tank. The inlet pipes of the electric oil pump and the manual oil pump extend into the hydraulic oil tank. The front end of the distribution pipe is simultaneously fixedly connected to the rear end of multiple fixed pipes. The front ends of the multiple fixed pipes are respectively fixedly connected to the rear end of multiple externally threaded pipes. The front sides of the multiple externally threaded pipes are respectively threadedly connected to multiple threaded sleeves. The threaded sleeves are rotatably connected to the upper outer surface of the connecting hose through bearings. The upper end face of the connecting hose overlaps with the front end face of the externally threaded pipe. The bottom right side of the hydraulic oil tank is fixedly connected to the left side of the placement plate, and the upper surface of the placement plate is provided with multiple placement slots.

[0005] A pressure gauge is fixedly installed on the oil outlet pipe of the electric oil pump, and the oil outlet pipe of the electric oil pump is fixedly connected to the rear end of the oil delivery pipe.

[0006] The front end of the oil delivery pipe is fixedly connected to the rear side of the oil distribution pipe and communicates with the interior of the oil distribution pipe. The rear side of the oil distribution pipe is also fixedly connected to the oil outlet pipe of the manual oil pump.

[0007] A second valve is fixedly installed on the oil pipeline, and a third valve is fixedly installed on the oil outlet pipe of the manual oil pump.

[0008] The bottom ends of the multiple connecting hoses are respectively connected to the interfaces of multiple hydraulic rods, and a valve is fixedly installed on each of the multiple fixed pipes.

[0009] A pressure plate is provided above the placement plate, and the upper surface of the pressure plate is fixedly connected to the bottom ends of the two sliding rods.

[0010] The two slide rods are respectively fitted into two through slots, both of which are opened in a fixed plate. The left side of the fixed plate is fixedly connected to the right side of the hydraulic oil tank.

[0011] The right sides of the two sliding rods overlap with the left ends of the two limiting bolts, and the two limiting bolts are threadedly connected to the two screw holes. The two screw holes are both opened on the right side of the fixing plate and are respectively connected to the two through slots.

[0012] The front side of the hydraulic oil tank is fixedly connected to the rear ends of two telescopic rods and two springs, with the two springs respectively sleeved on the outside of the two telescopic rods.

[0013] The front ends of the two springs and the two telescopic rods are fixedly connected to the left end of the fixing frame, and the right end of the fixing frame is fixedly connected to the left end of the winding rod.

[0014] The technical effects achieved by this utility model are as follows: This invention, by setting up four hydraulic rods connected to a hydraulic oil tank, allows for the lifting of a damaged vehicle to a height of 80cm during vehicle repairs in the field. This is particularly suitable for vehicles damaged in field conditions, such as complex terrain without trenches or other obstacles, providing support for different vehicle models and levels of damage. This enables mechanics to perform quick and effective repairs. Furthermore, when using this device, repair personnel can control individual hydraulic rods or use all four rods together according to actual repair needs, further improving the device's versatility. Additionally, a manual oil pump is included to ensure the device's continued operation even if the electric oil pump fails.

[0015] This invention features a placement plate and a pressure plate on the right side of the hydraulic oil tank. When not in use, multiple hydraulic rods can be placed in the placement slots, and the pressure plate can be pulled down to contact the upper end of the hydraulic rods, thus limiting and fixing them. Limiting bolts are used to fix the positions of the sliding rods and the pressure plate, securing the hydraulic rods to the placement plate for storage. Simultaneously, a winding rod is provided on the front side of the hydraulic oil tank. When not in use, the user can pull the winding rod forward to wrap multiple connecting hoses around it. Releasing the winding rod allows the spring force to pull it backward, causing the rear end of the connecting hoses to contact the hydraulic oil tank, thus squeezing and limiting them. This improves the overall integrity of the device, facilitating its transport and storage. Attached Figure Description

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figure 1-5 As shown, a multi-point hydraulic lift includes a hydraulic oil tank 1. An electric oil pump 2, a manual oil pump 4, and a distribution pipe 6 are fixedly installed on the upper end of the hydraulic oil tank 1. The oil inlet pipes of the electric oil pump 2 and the manual oil pump 4 extend into the hydraulic oil tank 1. The front end of the distribution pipe 6 is simultaneously fixedly connected to the rear end of multiple fixed pipes 14. The front ends of the multiple fixed pipes 14 are respectively fixedly connected to the rear end of multiple external threaded pipes 15. The front sides of the multiple external threaded pipes 15 are respectively threadedly connected to multiple threaded sleeves 16. The threaded sleeves 16 are rotatably connected to the upper outer surface of the connecting hose 7 through bearings. The upper end face of the connecting hose 7 overlaps with the front end face of the external threaded pipe 15. The bottom right side of the hydraulic oil tank 1 is fixedly connected to the left side of the placement plate 12. The upper surface of the placement plate 12 is provided with multiple placement slots 13. By providing a placement plate 12 on the right side of the hydraulic oil tank 1 and providing multiple placement slots 13 on the placement plate 12, the hydraulic rod 9 can be placed in the placement slots 13 for storage when the device is not in use.

[0020] Furthermore, a pressure gauge 3 is fixedly installed on the oil outlet pipe of the electric oil pump 2, and the oil outlet pipe of the electric oil pump 2 is fixedly connected to the rear end of the oil delivery pipe 5.

[0021] Furthermore, the front end of the oil supply pipe 5 is fixedly connected to the rear side of the oil distribution pipe 6 and communicates with the interior of the oil distribution pipe 6. The rear side of the oil distribution pipe 6 is also fixedly connected to the oil outlet pipe of the manual oil pump 4.

[0022] Furthermore, valve 25 is fixedly installed on the oil supply pipe 5, and valve 3 26 is fixedly installed on the oil outlet pipe of the manual oil pump 4. By installing the manual oil pump 4, when using the manual oil pump 4 to pump oil, valve 25 can be closed and valve 3 26 can be opened. Then, the handle of the manual oil pump 4 can be operated to pump out the hydraulic oil. Thus, even if the electric oil pump 2 is damaged, the manual oil pump 4 can still be used to ensure the normal operation of the device.

[0023] Furthermore, the bottom ends of multiple connecting hoses 7 are respectively connected to the interfaces of multiple hydraulic rods 9, and valves 17 are fixedly installed on multiple fixed pipes 14.

[0024] Furthermore, a pressure plate 11 is provided above the placement plate 12, and the upper surface of the pressure plate 11 is fixedly connected to the bottom ends of the two slide rods 23.

[0025] Furthermore, the two slide rods 23 are respectively fitted into the two through slots 22, both of which are opened in the fixed plate 10, and the left side of the fixed plate 10 is fixedly connected to the right side of the hydraulic oil tank 1.

[0026] Furthermore, the right sides of the two sliding rods 23 overlap with the left ends of the two limiting bolts 24 respectively. The two limiting bolts 24 are threadedly connected to the two screw holes 21 respectively. The two screw holes 21 are both opened on the right side of the fixing plate 10 and are respectively connected to the two through slots 22. After the hydraulic rod is placed in the placement slot, the user can rotate the limiting bolts 24 to make the ends of the limiting bolts 24 disengage from the sliding rods 23, and then pull the pressure plate 11 down to make the pressure plate 11 contact the top of the hydraulic rod 9. At this time, the limiting bolts 24 are rotated in the opposite direction to make the ends of the limiting bolts 24 contact the sliding rods 23 to restrict the position of the pressure plate 11, thereby effectively improving the stability of the hydraulic rod 9 during storage.

[0027] Furthermore, the front side of the hydraulic oil tank 1 is simultaneously fixedly connected to the rear ends of the two telescopic rods 18 and the two springs 19, with the two springs 19 respectively sleeved on the outside of the two telescopic rods 18.

[0028] Furthermore, the front ends of the two springs 19 and the two telescopic rods 18 are fixedly connected to the left end of the fixing frame 20, and the right end of the fixing frame 20 is fixedly connected to the left end of the winding rod 8. When the device is not in use, the user can pull the winding rod 8 forward and then wrap the multiple connecting hoses 7 around the winding rod 8. Then, by releasing the winding rod 8, the user can use the tension of the springs 19 to pull the winding rod 8 backward so that the rear end of the connecting hose 7 contacts the hydraulic oil tank 1 to squeeze and limit the connecting hose 7.

[0029] The working principle of this utility model is as follows: When using this device to assist maintenance personnel in repairing vehicles, the user can connect the end of the connecting hose 7 to the interface of the hydraulic rod 9, and place the four hydraulic rods 9 in the corresponding positions on the vehicle. Then, close valve 3 26 and open valve 2 25. The corresponding valve 1 17 can be opened according to the number of hydraulic rods 9 required. At this time, the electric oil pump 2 can be controlled to work so that the hydraulic oil in the hydraulic oil tank 1 is input into the hydraulic rods 9 through the oil supply pipe 5, the oil distribution pipe 6, and the connecting hose 7, so that the hydraulic rods 9 extend to lift the vehicle. When using the manual oil pump 4 to pump oil, valve 2 25 can be closed and valve 3 26 can be opened. Then, the manual oil pump 4 handle can be operated to pump out the hydraulic oil. After maintenance, the user can disassemble the interface between the connecting hose 7 and the hydraulic rod 9, and place the multiple hydraulic rods 9 into the multiple placement slots 13 respectively. At this time, the user can rotate the limiting bolt 24 so that the end of the limiting bolt 24 is disengaged from the slide rod 23, and then pull the pressure plate 11 down so that the pressure plate 11 contacts the top of the hydraulic rod 9. Then, rotate the limiting bolt 24 in the opposite direction so that the end of the limiting bolt 24 contacts the slide rod 23 to restrict the position of the pressure plate 11. Then, the user can pull the winding rod 8 forward and wrap the multiple connecting hoses 7 around the winding rod 8. Then, release the winding rod 8 and use the tension of the spring 19 to pull the winding rod 8 backward so that the rear end of the connecting hose 7 contacts the hydraulic oil tank 1 to squeeze and limit the connecting hose 7.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
