[0043] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0044] This embodiment relates to a rotary axle jacking device. In terms of the overall structure, as Figure 1 shown, it includes a base 1, a lifting mechanism 2, a rotating mechanism 3, a driving mechanism 4, and a bracket 5.

[0045] Among them, the lifting mechanism 2 is slidably arranged on the base 1, the rotating mechanism 3 is rotatably arranged on the top of the lifting mechanism 2, the axle rotates with the rotating mechanism 3, the driving mechanism 4 is arranged on the lifting mechanism 2 to drive the rotating mechanism 3 to rotate, and the bracket 5 is provided for placing the axle and is fixedly arranged on the upper part of the rotating mechanism 3.

[0046] It is worth mentioning that universal wheels can be provided at the lower part of the base 1, which are not shown in the attached drawings. The purpose is to facilitate the movement of the jacking device. The lifting mechanism 2 slides on the base 1 to achieve lifting. The axle is placed on its upper part, thereby driving the axle to lift, facilitating the installation of the axle on the vehicle body. The rotating mechanism 3 can follow the lifting of the lifting mechanism 2 and can also drive the axle to rotate, facilitating the alignment of the axle with the installation position and improving convenience. The driving mechanism 4 can drive the rotating mechanism 3 to rotate, facilitating operation, and can be locked in the rotated position, improving the installation efficiency. The bracket 5 is used to place the axle. The bracket 5 is installed on the rotating mechanism 3 and can not only follow the lifting of the lifting mechanism 2 but also follow the rotation of the rotating mechanism 3, thereby improving flexibility. A placement groove identical to the axle is provided at the top of the bracket 5 to facilitate the placement of the axle.

[0047] Based on the above overall introduction, an exemplary structure of the rotary axle jacking device of this embodiment is as Figure 2 and Figure 3 shown. The lifting mechanism 2 includes a first support rod 201 rotatably provided at one end on the base 1, a second support rod 202 slidably provided at one end on the base 1, and a platform 203 that follows the lifting of the first support rod 201 and the second support rod 202. The other ends of the first support rod 201 and the second support rod 202 are respectively slidably and rotatably provided at the bottom of the platform 203.

[0048] It should be noted that the first support rod 201 and the second support rod 202 are in a scissor shape. When the platform 203 rises, one ends of the first support rod 201 and the second support rod 202 slide on the platform 203 and the base 1 respectively. That is to say, sliding grooves need to be opened on the platform 203 and the base 1 respectively, and one ends of the first support rod 201 and the second support rod 202 can slide in the sliding grooves, while the other ends of the first support rod 201 and the second support rod 202 rotate on the platform 203 and the base 1 respectively. Such a setting realizes the lifting of the platform 203.

[0049] Preferably, still as Figure 2 and Figure 3 shown, a horizontal axis 204 is rotatably provided in the middle of the first support rod 201 and the second support rod 202 of this embodiment. A fixed rod 205 is fixedly provided on the first support rod 201. A driving member 206 is provided between the fixed rod 205 and the horizontal axis 204. Two groups of the first support rod 201 and the second support rod 202 are oppositely arranged between the base 1 and the platform 203.

[0050] Specifically, the horizontal axis 204 can be fixedly installed on the first support rod 201 or the second support rod 202. For example, if it is fixedly installed on the first support rod 201, then the second support rod 202 is rotatably arranged on the horizontal axis 204. The function of the fixed rod 205 is to provide support for the driving member 206. The driving member 206 can preferably be a hydraulic cylinder. The cylinder shaft of the hydraulic cylinder is connected to the fixed rod 205, and the piston rod shaft of the hydraulic cylinder is connected to the horizontal axis 204. With such a setting, when the hydraulic cylinder expands and contracts, it can drive the horizontal axis 204 to move, thereby realizing the folding of the first support rod 201 and the second support rod 202. This folding action drives the platform 203 to achieve a lifting action. The purpose of arranging two sets of the first support rod 201, the second support rod 202, and the driving member 206 respectively is to improve the stability during lifting.

[0051] As a preferred embodiment, as Figure 3 and Figure 4 shown, in this embodiment, the rotating mechanism 3 includes a rotating table 301 rotatably arranged on the platform 203, a wheel frame 302 fixedly arranged at the bottom of the rotating table 301, and rollers 303 rotatably arranged on the wheel frame 302. A plurality of the wheel frame 302 and the rollers 303 are evenly arranged in a circle on the rotating table 301.

[0052] It should be noted that the rotating table 301 and the platform 203 are arranged coaxially to ensure that the rotating table 301 can rotate on the platform 203. The wheel frame 302 can be fixed to the bottom of the rotating table 301 by screws for the rollers 303 to rotate. The rollers 303 roll on the platform 203. A plurality of the rollers 303 are evenly arranged along the central circular axis of the rotating table 301. With such a setting, the stability of the rotating table 301 during rotation can be improved. A plurality of the rollers 303 are in contact with the platform 203, thereby ensuring the uniformity of the force on the rotating table 301, improving the flexibility of the rotation of the rotating table 301, and avoiding friction between the rotating table 301 and the platform 203.

[0053] As a preferred embodiment, as Figure 5 shown, in this embodiment, the driving mechanism 4 includes a gear box 401 fixedly arranged at the bottom of the platform 203, and a central shaft 402 rotatably arranged inside the gear box 401. The central shaft 402 passes through the platform 203 and is fixedly connected to the rotating table 301. A driving shaft 403 is rotatably arranged on the side of the gear box 401. Bevel gears 404 are respectively fixedly arranged on the driving shaft 403 and the central shaft 402. A hand wheel 405 is fixedly arranged at one end of the driving shaft 403 extending out of the gear box 401. A locking member 406 is fixedly arranged on the side of the gear box 401. The locking member 406 is sleeved on the driving shaft 403.

[0054] It should be noted that the gearbox 401 can be fixedly installed at the bottom of the platform 203 by screws. The central shaft 402 is rotationally connected to the gearbox 401 and the platform 203 through bearings, and extends out from the platform 203. After extending out, it is fixedly connected to the rotating table 301. With such a setting, the central shaft 402 can drive the rotating table 301 to rotate. The drive shaft 403 is perpendicular to the central shaft 402, which is convenient for the installation of the bevel gears 404. The two bevel gears 404 are in meshing transmission. With such a setting, the central shaft 402 can be driven to rotate by rotating the drive shaft 403. The drive shaft 403 passes through the gearbox 401 through a bearing. The handwheel 405 is located on the drive shaft 403 outside the gearbox 401, which is convenient for driving the drive shaft 403 to rotate. The locking member 406 is respectively connected to the gearbox 401 and the drive shaft 403. By locking the locking member 406, the drive shaft 403 can be controlled to be fixed at this position, preventing the rotating table 301 from rotating by itself.

[0055] Preferably, as Figure 6 shown, the locking member 406 of this embodiment includes a fixed seat 4061 fixedly arranged on the gearbox 401, a diamond block 4062 fixedly arranged on the drive shaft 403, and a screw 4063 screwed on the side of the fixed seat 4061. A cavity 4064 is formed on the fixed seat 4061. The diamond block 4062 is located in the cavity 4064. One end of the screw 4063 extending into the cavity 4064 abuts against the diamond block 4062.

[0056] Specifically, the fixed seat 4061 is sleeved on the drive shaft 403 and fixedly installed on the gearbox 401 by screws. The diamond block 4062 is a polygon rectangular block and can be fixedly installed on the drive shaft 403 by screws. When the screw 4063 rotates and extends on the fixed seat 4061, it can abut against the plane of the diamond block 4062. With such a setting, the diamond block 4062 can be fixed, thereby fixing the drive shaft 403 at this position. When the screw 4063 is separated from the diamond block 4062, the handwheel 405 can continue to drive the drive shaft 403 to rotate. A threaded hole is formed on the fixed seat 4061. The threaded hole communicates with the cavity 4064, and the diamond block 4062 is located in the cavity 4064. With such a setting, the abutment between the screw 4063 and the diamond block 4062 can be realized.

[0057] In the rotary axle jacking device of this embodiment, through the stable lifting of the lifting mechanism 2 and the multi-angle rotation of the rotating mechanism 3, the rapid lifting and precise positioning of the axle can be realized, improving the production efficiency; through the cooperation of the driving mechanism 4 and the locking member 406, the flexible control and safe locking of the axle rotation can be realized, improving the convenience and safety of operation; through the structural design of the lifting mechanism 2 and the rotating mechanism 3, the stability and reliability of the device can be enhanced, reducing the labor intensity and improving the safety during the production process.

[0058] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
