[0035] The utility model discloses a side lifting machine's front view of one embodiment, and the side lifting machine includes driver 6, a pair of first guide rail 3, second guide rail 2 and support assembly 1.

[0036] As Figure 1 Shown, Figure 1 The utility model discloses a side lifting machine's front view of one embodiment, and the side lifting machine includes driver 6, a pair of first guide rail 3, second guide rail 2 and support assembly 1.

[0037] The both sides of driver 6 are provided with frame body 4, and first guide rail 3 is fixedly arranged on frame body 4 and is located at the both sides of driver 6 respectively, and one second guide rail 2 is slidably installed on each first guide rail 3, and the both ends of support assembly 1 are slidably connected with one second guide rail 2 respectively, wherein driver 6 is in transmission connection with support assembly 1 and is used to drive support assembly 1 to move along the vertical direction.

[0038] When the side lifting machine of the lifting station in the conveying line does not need to work, support assembly 1 is located at low position under the action of driver 6, when the vehicle body is conveyed to the lifting station and needs to be lifted, support assembly 1 is located at high position under the action of driver 6, and support assembly 1 lifts the vehicle body from the both sides of the vehicle body and separates the trolley carrying the vehicle body on the conveying line.

[0039] In this embodiment, the guide rails for guiding the lifting and lowering of the support assembly 1 are divided into two sections. When the support assembly 1 rises, after the travel of the second guide rail 2 is exhausted, the second guide rail 2 slides on the first guide rail 3, and the support assembly 1 continues to rise until the travel of the first guide rail 3 is also exhausted, and the support assembly 1 is located in a high position.

[0040] Exemplarily, the first guide rail 3 and the second guide rail 2 can be structural forms such as ball linear guides, cylindrical linear guides, etc. The first guide rail 3 and the second guide rail 2 are connected by a slider, and sliders are fixedly installed at both ends of the support assembly 1 and are slidably connected to the second guide rail 2 through the slider.

[0041] The side jacking machine of this embodiment divides the vertical guide structure into two sections to realize the two-stage lifting of the support assembly 1. When the lifting stroke of the vehicle body remains unchanged, the minimum longitudinal height of the vertical guide structure is reduced when the support assembly 1 is in a low position to avoid the vehicle body during transportation, thereby meeting the requirement of a lower conveying height of the transfer station of the conveyor line. When the transfer space is limited, a side jacking machine can also be set up to realize the lifting function of the vehicle body.

[0042] The driver 6 of this embodiment can adopt a linear drive structure, such as a power structure of a hydraulic cylinder or a pneumatic cylinder, as long as it can avoid the transportation of the vehicle body, so that the guide structure of the side lift machine avoids the transportation space of the vehicle body.

[0043] By setting the vertical guide structure as the first guide rail 3 and the second guide rail 2 which slide relatively, the two-stage lifting of the support assembly 1 is realized. When the longitudinal space of the conveyor line is limited, the vehicle body can be lifted while avoiding the vehicle body in the conveying process, thus meeting the requirements of the conveyor line.

[0044] In an exemplary embodiment, Figure 1 、 Figure 2 As shown, the driver 6 is a motor and also includes a transmission assembly 5. The output shaft of the driver 6 is transmission-connected to the support assembly 1 through the transmission assembly 5.

[0045] The driver 6 of this embodiment adopts a motor, which converts the rotation into the lifting movement of the support assembly 1 through the transmission assembly 5, further reducing the height of the side lift machine as a whole, reducing the minimum space occupancy rate of the side lift machine, and optimizing the overall layout of the car body conveyor line and its ancillary equipment.

[0046] In another exemplary embodiment, Figures 1-4As shown, the structure of the transmission assembly 5 includes a driven shaft 53 rotatably mounted on the frame 4, the driven shaft 53 is in transmission connection with the driver 6, the driven shaft 53 is fixedly mounted with a swing arm 52, and further includes a slide rail 51 fixedly mounted on the support assembly 1, the axis of the slide rail 51 is perpendicular to the axis of the first guide rail 3, and the swing end 520 of the swing arm 52 is in sliding connection with the slide rail 51. The driven shaft 53 is arranged in a horizontal direction, rotatably connected with the frame 4 through a bearing seat, one end of the driven shaft 53 is in transmission connection with the output shaft of the driver 6, and the other end of the driven shaft 53 is connected with the support assembly 1 through the swing arm 52, and the specific connection structure is as shown in Figure 1 As shown, the swing end 520 is eccentrically arranged relative to the driven shaft 53, and the swing end 520 is in sliding connection with the transverse slide rail 51 on the support assembly 1.

[0047] In this embodiment, the swing end 520 on the swing arm 52 swings in the vertical plane with the rotation of the motor output shaft, the swing end 520 is in sliding connection with the slide rail 51 on the support assembly 1, the spatial position change of the swing end 520 is converted into the lifting movement of the support assembly 1, and the overall longitudinal space occupied by the driver 6 and the transmission assembly 5 is distributed in the upward and downward directions of the motor transmission shaft, further compressing the space occupancy of the side top machine structure.

[0048] For example, the driven shaft 53 is fixedly mounted with a driven sprocket 530, the output shaft of the driver 6 is mounted with a driving sprocket 60, and the driven sprocket 530 and the driving sprocket 60 are in transmission connection through a chain.

[0049] In another exemplary embodiment, as shown in Figures 1-2 The number of transmission assemblies 5 is two, which are located on both sides of the driver 6, and the driving sprocket 60 is a double-row sprocket. The horizontal structure of the support assembly 1 is symmetrical about the output shaft of the driver 6, and the transmission assembly 5 uniformly transmits the power of the driver 6 to the support assembly 1 from both sides of the driver 6, ensuring the force balance of the support assembly 1 in the horizontal direction.
