Description

Technical Field

[0001] This utility model belongs to the technical field of vehicles, and in particular relates to a vehicle body lifting device. Background Technology

[0002] The logistics industry has a high demand for vehicles, especially specific-purpose vehicles such as forklifts, and some of these vehicles operate in relatively complex environments. Furthermore, the skill levels of different vehicle operators vary considerably. Therefore, during operation, vehicles often find their wheels stuck in mud, ditches, or manholes.

[0003] Currently, there are three main methods for getting vehicles out of trouble. The first is to pull the vehicle out of the stuck area using ropes. The second is to lift the vehicle body using jacks or similar tools and then insert hard materials under the stuck wheels. The third is to dig out the mud around the stuck wheels and then insert hard materials. The first method requires not only a rope in the vehicle but also a fixed point for the rope at the location where the vehicle is stuck, which places high demands on the environment and the physical strength of the operator. The second and third methods also require a certain level of physical strength from the operator, and most of the work needs to be done outside the vehicle. These methods mainly rely on operators using manpower, specific rescue equipment, or specific environments to get out of trouble. However, these methods are sometimes impossible due to limitations in manpower, lack of rescue equipment, or environmental conditions that do not allow operators to stay outside the vehicle for extended periods. Furthermore, relying primarily on operators for rescue also poses certain risks to the personal safety of the operators. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle body lifting device to solve the problem that vehicles are stuck and cannot be freed due to limited manpower or lack of rescue equipment, as well as the risk to the personal safety of operators when they try to free the vehicle manually.

[0005] To solve the above problems, this utility model provides a vehicle body lifting device, including a vehicle body lifting assembly and a connecting rod. The vehicle body lifting assembly includes a first hydraulic telescopic part and a second hydraulic telescopic part. The lower part of the first hydraulic telescopic part is provided with a first sliding cavity, and the upper part of the second hydraulic telescopic part is slidably connected to the first sliding cavity. The lower end of the second hydraulic telescopic part is used to contact the ground.

[0006] The first hydraulic telescopic part is provided with two first oil inlets and outlets, both of which are connected to the first sliding cavity. The two first oil inlets and outlets are used for oil to enter and flow out of the vehicle body lifting assembly, respectively.

[0007] The first oil inlet and outlet are also connected to a first oil flow pipe, and the end of the first oil flow pipe away from the first oil inlet and outlet is connected to the vehicle's oil pump.

[0008] One end of the connecting rod is fixedly connected to the first hydraulic telescopic part, and the other end of the connecting rod is connected to the vehicle body.

[0009] Furthermore, a rotating assembly is provided between the connecting rod and the vehicle body. The rotating assembly includes a fixed base and a rotating shaft. The other end of the connecting rod is connected to the rotating shaft, which rotates horizontally and is connected to the fixed base. The fixed base is fixedly connected to the vehicle body.

[0010] The vehicle body is also equipped with a buckle assembly, which is used to secure the first hydraulic telescopic part.

[0011] Furthermore, the lower end of the second hydraulic telescopic part is also provided with a ground contact part, which is a circular disk with a diameter larger than that of the second hydraulic telescopic part.

[0012] Furthermore, a multi-way control valve is installed between the first oil flow pipeline and the oil pump.

[0013] Furthermore, the connecting rod is a telescopic structure, comprising a first connecting part and a second connecting part. A portion of the second connecting part is sleeved within the first connecting part. The end of the first connecting part away from the second connecting part is fixedly connected to the first hydraulic telescopic part, and the end of the second connecting part away from the first connecting part is fixedly connected to the rotating shaft.

[0014] Furthermore, the connecting rod is a hydraulic device, and the first connecting part is provided with two second oil inlets and outlets. The second oil inlets and outlets are connected to second oil flow pipes, and the end of the second oil flow pipe away from the second oil inlets and outlets is connected to a multi-way control valve.

[0015] Furthermore, the vehicle body is equipped with multiple body lifting components, and the first oil flow pipe connected to each body lifting component is connected to a multi-way control valve.

[0016] Furthermore, the fixed base and the rotating shaft are detachably connected.

[0017] The advantages of this vehicle body lifting device are as follows: Compared with the prior art, the device incorporates a vehicle body lifting assembly and a connecting rod. The lifting assembly is fixedly connected to the connecting rod, which is then fixed to the vehicle body. The lifting assembly also features a first oil inlet / outlet for hydraulic lifting. The oil enters the lifting assembly from the vehicle's own oil pump via a first oil flow pipe. Since the oil comes from the vehicle itself, there is no need for additional hydraulic pumps or other equipment. The operator only needs to operate the oil pump inside the vehicle to lift the vehicle body by extending the lifting assembly. This process requires less physical strength from the operator, as they only need to operate the oil pump. Furthermore, there is no need to operate outside the vehicle. The operator then simply places nearby hard materials such as planks or stones under the lifted tires. The entire process can be completed by only one operator, requiring less physical strength and eliminating the need for specialized traction devices. Because the operation is simple and almost entirely performed inside the vehicle, the risk to the operator's personal safety is minimal. Attached Figure Description

[0021] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 3 The present invention provides a more detailed description of a vehicle body lifting device.

[0022] like Figure 1As shown in the figure, an embodiment of the present invention discloses a vehicle body lifting device, which includes a vehicle body lifting assembly 100 and a connecting rod 200. The vehicle body lifting assembly 100 is designed to be telescopic. The vehicle body lifting assembly 100 includes a first hydraulic telescopic part 110 and a second hydraulic telescopic part 120, wherein both the first hydraulic telescopic part 110 and the second hydraulic telescopic part 120 are cylindrical in shape, and the first hydraulic telescopic part 110 is hollow, so that a portion of the second hydraulic telescopic part 120 is fitted inside the first hydraulic telescopic part 110. The first hydraulic telescopic part 110 and the second hydraulic telescopic part 120 are slidably connected, and the end of the second hydraulic telescopic part 120 away from the first hydraulic telescopic part 110 is used to contact the ground. At the same time, the first hydraulic telescopic part 110 is provided with two first oil inlets and outlets 111, which are used for oil to enter and exit the vehicle body lifting assembly 100.

[0023] The vehicle includes a vehicle body lifting assembly 100 and a connecting rod 200. The vehicle body lifting assembly 100 includes a first hydraulic telescopic section 110 and a second hydraulic telescopic section 120. The lower part of the first hydraulic telescopic section 110 is provided with a first sliding cavity. The upper part of the second hydraulic telescopic section 120 is slidably connected to the first sliding cavity, and the lower end of the second hydraulic telescopic section 120 is used to contact the ground. The first hydraulic telescopic section 110 is provided with two first oil inlets and outlets 111, both of which are connected to the first sliding cavity. The two first oil inlets and outlets 111 are used for oil to enter and exit the vehicle body lifting assembly 100, respectively.

[0024] In this invention, a first oil flow pipe 112 is also connected to the first oil inlet / outlet 111, and the end of the first oil flow pipe 112 away from the first oil inlet / outlet 111 is connected to the vehicle's oil pump 400. The hydraulic fluid used by the vehicle body lifting assembly 100 for hydraulic lifting is entirely supplied by the vehicle's own oil pump 400. This eliminates the need for a dedicated oil pump, reducing the difficulty of deploying the vehicle body lifting device.

[0025] In some embodiments, one end of the connecting rod 200 is fixedly connected to the first hydraulic telescopic part 110, and the other end of the connecting rod 200 away from the first hydraulic telescopic part 110 is fixedly connected to the vehicle body 700. For example, the fixed connection is made by welding.

[0026] When a vehicle needs to get out of trouble, the operator does not need to get out of the vehicle to lift it. Instead, from inside the vehicle, the operator operates the oil pump 400 to supply oil to the vehicle lifting assembly 100, causing the assembly to extend. Specifically, the second hydraulic telescopic section 120 extends away from the first hydraulic telescopic section 110. Once the end of the second hydraulic telescopic section 120 away from the first hydraulic telescopic section 110 touches the ground, the vehicle lifting assembly 100 extends further. As the second hydraulic telescopic section 120 moves away from the first hydraulic telescopic section 110, the side equipped with the vehicle lifting device also rises away from the ground. Once the wheel that needs to be freed has left the ditch, the operator can get out of the vehicle and insert hard materials such as planks or stones from the surrounding environment or carried in the vehicle between the wheel and the ditch. The operator can then return to the vehicle; if suitable materials are available on the vehicle, the operator can insert them under the wheel without getting out. Then, the hydraulic pump 400 is operated to retract the vehicle lifting assembly 100, that is, the second hydraulic telescopic part 120 moves closer to the first hydraulic telescopic part 110. Once the second hydraulic telescopic part 120 is out of contact with the ground, the wheel to be freed is then supported by the previously inserted hard material. At this point, the operator only needs to move the vehicle forward or backward to free it. Throughout the process, the operator only needs to operate the hydraulic pump for most of the time, requiring relatively little physical strength, and the entire process poses no risk to the operator's personal safety.

[0027] like Figure 2 As shown, another embodiment includes a rotating assembly 300 between the connecting rod 200 and the vehicle body 700. This rotating assembly 300 includes a fixed base 310 and a rotating shaft 320. The end of the connecting rod 200 away from the first hydraulic telescopic part 110 is connected to the rotating shaft 320. The rotating shaft 320 is rotatably connected to the fixed base 310 in a horizontal direction. The fixed base 310 is fixedly connected to the vehicle body 700. The axial direction of the rotating shaft 320 is parallel to the direction in which the second hydraulic telescopic part 120 slides inside the second hydraulic telescopic part 120, and the rotation direction of the vehicle body lifting assembly 100 is perpendicular to the direction in which the second hydraulic telescopic part 120 slides inside the second hydraulic telescopic part 120. Simultaneously, a latching assembly 500 is also provided on the vehicle body 700 to secure the first hydraulic telescopic part 110.

[0028] This implementation method is more versatile because the connecting rod 200 can drive the vehicle body lifting assembly 100 to rotate relative to the vehicle body 700, and it can find a more suitable ground to lift the vehicle body lifting assembly 100 when stuck.

[0029] In use, the operator first releases the vehicle lifting assembly 100 by opening the latch assembly 500, then rotates the vehicle lifting assembly 100. At this point, the vehicle lifting assembly 100 can rotate on an arc with the connecting rod 200 as the radius and the rotation axis 320 as the center. Once the vehicle lifting assembly 100 has rotated to the appropriate position, the operator operates the oil pump 400 to extend the vehicle lifting assembly 100, and then inserts a hard material under the wheel. After the vehicle is freed, the lifting assembly 100 is retracted. Then, the vehicle lifting assembly 100 is rotated back to the latch assembly 500, which secures the vehicle lifting assembly 100 to the vehicle body 700. Without the latch assembly 500 securing the vehicle lifting assembly 100, unnecessary movement of the vehicle lifting assembly 100 may occur during normal vehicle use, posing a danger to the vehicle and related personnel.

[0030] This design expands the applicability of the vehicle lifting device. Although it requires an operator to rotate the vehicle lifting component 100, this operation requires minimal physical exertion and poses no risk to the operator's safety. If the environment allows the operator to disembark, they can unlock, rotate, and lock the vehicle lifting component 100. If the environment does not allow disembarkation, the operator can still perform the relevant operations from inside the vehicle, as the rotating component 300 and the latching component 500 are located on the vehicle body, close to the operator. This design expands the applicability of the vehicle lifting device without increasing the physical exertion required of the operator or posing any risk to their safety.

[0031] Understandably, the lower end of the second hydraulic telescopic part 120 is also provided with a ground contact part 130. The side of the ground contact part 130 that is connected to the second hydraulic telescopic part 120 is a circular disk with a diameter larger than that of the second hydraulic telescopic part 120.

[0032] By providing the ground contact part 130, the contact area of ​​the vehicle lifting assembly 100 can be increased, making the contact between the vehicle lifting assembly 100 and the ground more stable and reducing the risk of the vehicle lifting assembly 100 sinking into the ground; on some soft ground, the vehicle lifting assembly 100 can lift the vehicle more easily.

[0033] like Figure 3 As shown, a multi-way control valve 600 is also provided between the first oil flow pipe 112 and the oil pump 400. This multi-way control valve 600 can be used for the inlet and outlet of multiple oil channels.

[0034] The connecting rod 200 can also be designed as a telescopic structure. The connecting rod 200 includes a first connecting portion 210 and a second connecting portion 220. A portion of the second connecting portion 220 is fitted into the first connecting portion 210. The end of the first connecting portion 210 away from the second connecting portion 220 is fixedly connected to the first hydraulic telescopic portion 110, and the end of the second connecting portion 220 away from the first connecting portion 210 is fixedly connected to the rotating shaft 320. The connecting rod 200 is a hydraulic device. The first connecting portion 210 is provided with two second oil inlets and outlets 211. Second oil flow pipes 212 are connected to the second oil inlets and outlets 211. The end of the second oil flow pipes 212 away from the second oil inlets and outlets 211 is connected to the multi-way control valve 600. This design can further expand the applicability of the vehicle body lifting assembly 100. This allows the vehicle lifting assembly 100 to not only move on an arc, but also to find a suitable place on a fan-shaped surface to extend and retract to lift the vehicle, enabling the vehicle to get out of trouble more quickly. The extension and retraction of the connecting rod 200 can also be completed by the operator operating the oil pump 400.

[0035] Understandably, the vehicle body 700 is equipped with multiple vehicle body lifting components 100. Each vehicle body lifting component 100 is connected to a first hydraulic flow pipe 112 that is connected to a multi-way control valve 600. This ensures that when the wheels in different directions need to get out of trouble, there is a suitable vehicle body lifting component 100 to lift the vehicle body 700, helping the vehicle to get out of trouble. Furthermore, the fixed base 310 and the rotating shaft 320 are detachably connected, allowing the vehicle body 700 to be equipped with multiple fixed bases 310. Only one or two of the vehicle body lifting component 100, connecting rod 200, and rotating shaft 320 need to be configured. When needed, the vehicle body lifting component 100, connecting rod 200, and rotating shaft 320 assembly can be disassembled from other fixed bases 310 and installed onto a suitable fixed base 310, thereby increasing the applicability of the vehicle body lifting component 100.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
