DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figure 1-4 As shown, the utility model provides a modular hydraulic lifting device, including a mounting frame 1, two movable grooves 2 are symmetrically arranged on the inner side of the mounting frame 1, and a rotating shaft 3 is also installed on the inner side of the mounting frame 1, and both ends of the rotating shaft 3 are respectively inserted into the two movable grooves 2 and are rotatably connected with the inner walls of the movable grooves 2, and the surfaces of the inserted parts are respectively provided with first connecting blocks 4, and a lifting module 5 is installed on the top of the first connecting blocks 4, and the surfaces of the parts of the rotating shaft 3 located in the two movable grooves 2 are provided with threads, and the two first connecting blocks 4 are threadedly connected to the threads on the surfaces of the rotating shaft 3.

[0024] The threads on the surfaces of the rotating shafts 3 in different movable grooves 2 have opposite directions. When the rotating shaft 3 rotates, the two first connecting blocks 4 drive the two lifting modules 5 to move closer to or away from each other.

[0025] Among them, the jacking module 5 includes a movable frame 501, a connecting rod structure 502, a hydraulic rod 503 and a lifting frame 504. The movable frame 501 is fixedly connected to the first connecting block 4, and the movable frame 501 and the lifting frame 504 are connected through the connecting rod structure 502. The connecting rod structure 502 is composed of two groups of connecting rods, specifically a parallel connecting rod structure 502. The two groups of connecting rods constituting the connecting rod structure 502, the movable frame 501, and the lifting frame 504 form a parallelogram structure. In the process of jacking the car, the two groups of connecting rods always remain parallel, and the movable frame 501 and the lifting frame 504 also remain parallel. The two ends of the hydraulic rod 503 are respectively connected to the movable frame 501 and the lifting frame 504 for rotation, and the lifting frame 504 is pushed up by the hydraulic rod 503 to jack up the car.

[0026] A motor 6 is fixedly mounted on the inner side of the mounting frame 1 , and the output end of the motor 6 is connected to the rotating shaft 3 via a bevel gear set. The motor 6 drives the rotating shaft 3 to rotate via the bevel gear set.

[0027] Among them, second connecting blocks 7 are symmetrically arranged on both sides of the first connecting block 4 at the bottom of the movable frame 501, and two supporting guide rods 8 are symmetrically arranged on both sides of the rotating shaft 3 on the inner side of the movable groove 2. The two supporting guide rods 8 respectively penetrate the two second connecting blocks 7, and the second connecting blocks 7 are slidingly connected to the supporting guide rods 8. The supporting guide rods 8 are used to bear the load of the jacking module 5 to lift the car, thereby reducing the load applied to the rotating shaft 3.

[0028] Among them, support legs 9 are arranged at the four corners of the bottom of the mounting frame 1, and the support legs 9 constitute a first support module, which is used to support the mounting frame 1 during the process of lifting the vehicle.

[0029] Among them, two connecting sleeves 10 are symmetrically installed on both sides of the mounting frame 1, and a movable rod 11 is installed on the inner side of the connecting sleeve 10. The top and bottom ends of the movable rod 11 respectively pass through the top and bottom of the connecting sleeve 10, and the top and bottom ends of the movable rod 11 are respectively provided with a limiting plate 12 and a universal wheel 13, and the universal wheel 13 is installed, which is used for the movement of the utility model.

[0030] Among them, the surface of the movable rod 11 is covered with a spring 14, and the two ends of the spring 14 are respectively against the bottom of the connecting sleeve 10 and the top of the universal wheel 13. The connecting sleeve 10 spring 14, the movable rod 11, the limit plate 12, the universal wheel 13 and the spring 14 together constitute a second support module. The elastic force of the spring 14 is greater than the overall mass of the utility model, so that when the vehicle is not lifted, the mounting frame 1 will be lifted to lift the supporting leg 9 off the ground, so that the supporting leg 9 will not affect the movement of the mounting frame 1.

[0031] Specific working principle:

[0032] Before using the utility model, firstly connect the utility model to an external power supply and a control panel, and control the operation of the utility model through the external control panel. During the use of the utility model, according to the different widths of the cars, the motor 6 of the utility model is started through the external control panel, and the motor 6 drives the rotating shaft 3 to rotate through the bevel gear set, so that the two first connecting blocks 4 located in different movable grooves 2 and respectively connected to the surface of the rotating shaft 3 in different directions can respectively drive the two jacking modules 5 to move closer to or away from each other, so as to achieve the effect of changing the distance between the two lifting plates, so that the utility model can lift cars of different widths. After the distance adjustment is completed, the utility model is moved to the bottom of the car through the universal wheel 13, and the hydraulic rod 503 in the utility model is started through the external control panel. When the hydraulic rod 503 and the connecting rod structure 502 cooperate, the lifting plate rises to lift the car. At the same time, in the process of the lifting plate lifting the car, the weight of the car will gradually be applied to the mounting frame 1, so that the spring 14 will gradually shrink. The mounting frame 1 moves down with the shrinkage of the spring 14 until the support leg 9 contacts the ground. At this time, the support leg 9 replaces the universal wheel 13 to support the mounting frame 1, thereby preventing the mounting frame 1 from moving, thereby improving the stability of the vehicle after jacking.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
