[0031] Reference Figure 1-Figure 6 As shown, this embodiment provides a specific implementation method regarding a mobile lifting device for disassembling and assembling a power source, including a lift 10, a placement table 20 and a blocking rod 30. The placement table 20 for placing the power source is installed in a disassembled manner on the top surface of the lift 10. There are a plurality of blocking rods 30 that are evenly distributed at the four corners of the top surface of the lift 10 to block the power source.

[0032] The utility model adjusts the height of the entire tooling through the lift 10, and a high-strength limiting column 103 is installed at the bottom end of the lifting sleeve 102 of the lift 10 to transfer the bearing pressure of the lifting sleeve 102, and the placement table 20 can place the power source, increase the thickness of the lifting platform 101 of the lift 10, and avoid direct impact on the lifting platform 101 when a heavy engine or gearbox is placed, and detachable or installable blocking rods 30 are set at the four corners of the lifting platform 101 to block and limit the engine or gearbox.

[0033] Among them, the elevator 10 includes a lifting platform 101, a lifting sleeve 102, a limiting column 103, a base 104 and a screw jack 105. The lifting platform 101 and the base 104 are arranged parallel to each other. There are a number of lifting sleeves 102 that support the four corners of the lifting platform 101 and the base 104. A limiting column 103 is installed on the outer periphery of the bottom end of each lifting sleeve 102, and a screw jack 105 is installed in the middle of the lifting platform 101 and the base 104. The screw jack 105 drives the lifting platform 101 to move up and down.

[0034] The screw jack 105 described here is a mechanical jack, which is driven by manpower through a screw pair, and a screw rod or a nut sleeve is used as a lifting piece, which can support the weight of the power source of the car.

[0035] The utility model uses a screw jack 105 as the lifting power of the elevator 10, which can be used for mechanical adjustment. The screw jack 105 drives the lifting platform 101 to move up and down, and the lifting sleeves 102 distributed in the four corners between the lifting platform 101 and the base 104 are synchronously raised or lowered with the lifting platform.

[0036] Furthermore, the limiting column 103 includes a filling layer 131, a first cylinder 132, and a second cylinder 134. The second cylinder 134 is located in the middle of the first cylinder 132, and the second cylinder 134 is mounted on the outside of the bottom end of the lifting sleeve 102. The filling layer 131 is arranged between the outer wall of the first cylinder 132 and the inner wall of the second cylinder 134.

[0037] Furthermore, the filling layer 131 is cast by concrete.

[0038] Furthermore, a plurality of steel bars 133 are embedded in the filling layer 131 , and the steel bars 133 are distributed at equal distances.

[0039] The structure formed by the first cylinder 132, the second cylinder 134 and the filling layer 131 located in the middle and made of steel bars and concrete has strong bearing capacity and is not prone to deformation, so as to bear the maximum pressure.

[0040] In one specific embodiment, the second cylinder 134 and the first cylinder 132 are both hollow cylinders, and the inner diameter of the second cylinder 134 is 3-5 cm larger than the outer diameter of the bottom end of the lifting sleeve 102 .

[0041] And, the lifting sleeve 102 includes an inner cylinder and an outer cylinder, and the inner cylinder moves up and down in the outer cylinder;

[0042] The height of the limiting column 103 is higher than the outer cylinder of the lifting sleeve 102 .

[0043] When disassembling the engine or gearbox from the car, the limit column 103 serves as the main supporting force. After the overall disassembly is completed, when cleaning and maintaining the engine or gearbox, the pressure of the lifting sleeve 102 is transferred, because the power source of the car is at least 70 kg, and as much as 200 kg, which reduces the loss of the lifting sleeve.

[0044] The placement platform 20 includes a bearing platform 201 fixed at the center of the lifting platform 101, which increases the thickness of the lifting platform 101 of the lift 10 to avoid direct impact on the lifting platform 101 when placing a heavy engine or gearbox;

[0045] and a support platform 202 located on the side of the carrying platform 201;

[0046] The distance between the support platform 202 and the bearing platform 201 is adjusted by a plurality of telescopic rods 203 to support or clamp the engine and the gearbox. The support platform 202 and the bearing platform 201 are suitable for engines or gearboxes of different specifications and are highly practical.

[0047] In one specific embodiment, threaded holes are provided at the four corners of the lifting platform 101, and the blocking rod 30 is tilted on the lifting platform 101 at a preset angle A. The preset angle A here is 40-60°. The external shapes of the engine and gearbox are very irregular and can be easily stuck to avoid outward movement during movement.

[0048] In one specific embodiment, a plurality of moving wheels 40 are installed at the bottom of the base 104 of the lift 10 to facilitate the movement of the entire device.

[0049] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
