The support block 19 is a supporting structure with a concave arc surface on the upper surface.

[0048] The specific operating principle of the present invention is:

[0049] Chassis Movement:

[0050] The chassis system has four omnidirectional wheel 25 assemblies, each wheel having a latch. When the latch is locked, the direction is locked and the wheel can be used as a directional wheel. When the latch is pulled out, the wheel has an omnidirectional movement function.

[0051] The chassis system also has eight retractable auxiliary legs 26. When stable parking is required, the latch of the locking rod is pulled out, the locking rod is pulled out, and then the locking rod is locked with the latch. The rotating rod is rotated to make the parking legs 26 touch the bottom.

[0052] The chassis system is provided with a stabilizer bar assembly 29, which is extended and retracted as the lifting system rises and falls, thereby preventing the hanging object from tilting due to excessive lifting.

[0053] Install the vehicle for lifting:

[0054] The control system provides power to the hydraulic cylinder to raise or lower the inner shear arm 33. The input and output of the hydraulic cylinder can be controlled manually or electrically. In the manual mode, the operator manually pressurizes the hydraulic cover; in the electrically controlled mode, the pressure in the hydraulic cover is controlled by the electronic control device after power is applied.

[0055] When the support rod of the hydraulic cylinder extends, it drives the inner scissor arm 33 to rotate toward the scissor arm transfer pin 35. Under the action of the inner scissor arm 33, the outer scissor arm 34 drives the scissor arm sliding mounting seat 32 to slide toward the inner side of the frame 24 on the sliding guide rail 28. At this time, the posture adjustment system connected to the inner scissor arm 33 and the outer scissor arm 34 moves upward. Conversely, the support rod of the hydraulic cylinder retracts and the posture adjustment system descends.

[0056] During the raising or lowering of the lifting system:

[0057] The inner scissor arm 33 is connected to the fixed connecting seat, which cannot move. The outer scissor arm 34 is connected to the movable mounting seat, which can slide on the adjusting plate 1-2. When the lifting system rises, the sliding mounting seat slides along the side of the adjusting plate 1-2 close to the fixed connecting seat. When the lifting system descends, the sliding mounting seat slides along the side of the adjusting plate 1-2 close to the fixed connecting seat.

[0058] The telescopic rod 29-1 in the stabilizing rod assembly 29 fixed at the lower end of the posture adjustment system also extends and retracts during the rising and falling of the lifting system. At the same time, the telescopic rod 29-1 extends and retracts, and the circular ring on the outer side of the lower rod of the telescopic rod 29-1 hinged on the support hinge seat 29-3 also slides on the guide frame 29-2, providing certain support for the stabilizing rod assembly 29; during the rising process of the lifting system, the movable connecting seat slides toward the side close to the fixed connecting seat, and the center of gravity of the posture adjustment system shifts at this time, and the telescopic rod 29-1 of the stabilizing rod assembly 29 provides further balancing support for the posture adjustment system.

[0059] Install the car for posture adjustment:

[0060] When the posture adjustment system needs to be adjusted longitudinally, the front longitudinal platform 3 and the rear longitudinal platform 4 are connected to the synchronization tube 22, and the front longitudinal platform 3 is adjusted to a suitable position on the synchronization tube 22. The longitudinal screw 5 is driven by the transverse handwheel 5-1, and the rear longitudinal platform 4 is made to slide longitudinally linearly along the longitudinal track 2 under the action of the longitudinal nut seat 23. The front longitudinal platform 3 connected to the rear longitudinal platform 4 also makes synchronous movement at the same speed and direction along the longitudinal guide rail 2.

[0061] When the posture adjustment system needs to be adjusted laterally, the front transverse handwheel 9-2 and the rear transverse handwheel 10-2 are rotated at the same speed and in the same direction at the same time, so that they drive the front transverse platform 7 and the rear transverse platform 8 connected by the front transverse nut seat 11 and the rear transverse nut seat 12 on the front transverse screw 9 and the rear transverse screw 10 to perform synchronous transverse linear sliding on the transverse guide rail group 6 provided on the front longitudinal platform 3 and the rear longitudinal platform 4.

[0062] In addition, when the posture adjustment system moves longitudinally, the front transverse screw platform 9-1 and the rear transverse screw platform 10-1, which are connected to the front longitudinal platform 3 and the rear longitudinal platform 4 through the front transverse nut seat 11 and the rear transverse nut seat 12, are also driven by the longitudinal screw 5 to slide longitudinally linearly along the longitudinal guide rail 2.

[0063] When the posture adjustment system needs to be rotated and adjusted, if the front transverse handwheel 9-2 does not move, only the rear transverse handwheel 10-2 is rotated to make the rear transverse screw 10 drive the rear transverse platform 8 to slide horizontally linearly along the transverse guide rail group 6. At this time, the adjusted workpiece is placed on one end of the rear support connecting seat 16 and rotates around the front support platform 15; if the rear transverse handwheel 10-2 does not move, only the front transverse handwheel 9-2 is rotated to make the front transverse screw 9 drive the front transverse platform 7 to move horizontally linearly along the transverse guide rail group 6. At this time, the adjusted workpiece is placed on one end of the front support platform 15 and rotates around the rear support connecting seat 16.

[0064] In addition, the posture adjustment system is provided with a front support point and two rear support points. The front support point is formed by contact with the support block 19 on the front support platform 15 connected to the front vertical adjustment screw 13, and the two rear support points are formed by contact with the two rear support connecting seats 16 connected to the rear vertical adjustment screw 1 14-1 and the rear vertical adjustment screw 2 14-2 respectively.

[0065] In addition, in order to maintain the stability of the adjusted workpiece during rotational motion, the local longitudinal movement platform 1 8-3 and the local longitudinal movement platform 2 8-4 slide back and forth on the guide rail seat 1 8-1 and the guide rail seat 2 8-2 respectively, as longitudinal displacement compensation during rotational motion and pitching motion.

[0066] When the posture adjustment system needs to be adjusted vertically, the front support handwheel 13-1, the rear support handwheel 1 14-3 and the rear support handwheel 2 14-4 are rotated at the same speed and in the same direction at the same time, so that they drive the front vertical adjustment screw 13 and the rear vertical adjustment screw 14 to make the front support platform 15 and the rear support connecting seat 16 perform synchronous linear motion in the vertical direction.

[0067] When the posture adjustment system needs to be pitched, if the front support handwheel 13-1 does not move, only the rear support handwheel 14-3 and the rear support handwheel 2 14-4 are rotated at the same speed and in the same direction, so that they drive the rear vertical adjustment screw 14 to make an upward or downward linear motion in the vertical direction. At this time, the adjusted workpiece makes a pitch motion around the front support platform 15 on the rear support connecting seat 16; if the rear support handwheel 14-3 and the rear support handwheel 2 14-4 do not move, only the front support handwheel 13-1 is rotated, so that it drives the front vertical adjustment screw 13 to make an upward or downward linear motion in the vertical direction. At this time, the adjusted workpiece makes a pitch motion around the rear support connecting seat 16 on the upper front support platform 15.

[0068] In addition, in order to maintain the stability of the adjusted workpiece during pitching motion, the local longitudinal moving platform 1 8-3 and the local longitudinal moving platform 2 8-4 slide back and forth on the guide rail seat 1 8-1 and the guide rail seat 2 8-2 respectively, as longitudinal displacement compensation during rotational motion and pitching motion.

[0069] When the posture adjustment system needs to be rolled, the front support handwheel 13-1 remains stationary, and only one of the rear support handwheel 14-3 and the rear support handwheel 2 14-4 is rotated alone, so that it drives any one of the rear vertical adjustment screw 14-1 and the rear vertical adjustment screw 2 14-2 to perform linear movement in the vertical direction. At this time, the adjusted workpiece is controlled to roll in the forward or reverse direction according to the position of the rear vertical adjustment screw 14.

[0070] In addition, in order to maintain the stability of the adjusted workpiece during rolling motion, the ball bearing 21 in the front support 15 rolls around the sliding rod 20 on the bottom arc surface of the roller bracket 17, and the sliding rod 20 is embedded in the arc groove 17-1 in the roller bracket 17. The sliding rod 20 slides in the arc groove 17-1 according to the sliding position of the ball bearing 21.

[0071] In addition, the specific application effects of the posture adjustment mechanism of the present invention are as follows: Figure 11-13 Shown are the actual placement renderings of Type A engine, Type B engine and V-tail.
