[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 4 As shown in this embodiment, a stable jacking structure includes a base 1, two concave plates 2 are fixedly connected in the base 1, a hydraulic press 1 3 and a hydraulic press 2 4 are fixedly connected to the two concave plates 2, a moving rod 1 5 is slidably connected in the hydraulic press 1 3, a moving rod 2 6 is slidably connected in the hydraulic press 2 4, a top plate 9 is fixedly connected to the top of the moving rod 2 6, two reinforcing plates 10 are rotatably connected in the moving rod 1 5, two reinforcing plates 2 11 are rotatably connected in the moving rod 2 6, and two positioning plates 12 are fixedly connected to the bottom of the top plate 9.

An adjustment structure 7 is connected to the bottom of the top plate 9, which is connected with the reinforcement plate 10 and the reinforcement plate 2 11. The adjustment structure 7 includes a sleeve plate 701, a gear 1 704 and a gear 2 705. A multi-station tooth plate 703 is slidably connected inside the sleeve plate 701. An auxiliary block 706 is fixedly connected to one side of the multi-station tooth plate 703, and a telescoping device 702 is fixedly connected to one side of the sleeve plate 701.

[0021] like Figure 1 and Figure 3As shown, a number of supporting legs are provided at the bottom of the base 1, the bottom of the top plate 9 is fixedly connected to the top of the moving rod 5, the reinforcing plate 10 is clamped in the positioning plate 12, the reinforcing plate 2 11 is clamped in the positioning plate 12, the reinforcing plate 10 overlaps the positioning plate 12, and the locking structure 8 includes an auxiliary plate 801, the auxiliary plate 801 is fixedly connected between the two positioning plates 12, two slides 805 are slidably connected in the auxiliary plate 801, a rotating rod 802 is rotatably connected in the auxiliary plate 801, and a rotating rod 802 is fixedly connected outside the rotating rod 802. Plate 804, the back of the auxiliary plate 801 is fixedly connected with a motor 803, the output shaft of the motor 803 is connected to the rotating rod 802, the motor 803 drives the rotating rod 802 to rotate forward and reverse, the front of the rotating plate 804 is connected to two connecting plates 806, the rotating plate 804 is connected to the slide plate 805 through the connecting plates 806, one side of the slide plate 805 is connected to a limiting rod 807, the limiting rod 807 is clamped in the positioning plate 12, the limiting rod 807 is clamped with the reinforcement plate 10, and the limiting rod 807 is clamped with the reinforcement plate 2 11.

[0022] By setting a rotating plate 804, a connecting plate 806 and a positioning plate 12, the rotating plate 804 is driven by the motor 803 to rotate around the rotating rod 802. Since the rotating plate 804 is connected to the corresponding slide 805 through the connecting plate 806, the two slides 805 will move relative to each other in the auxiliary plate 801, and the slide 805 can move evenly, avoiding the position shift of the slide 805 when moving, and the reinforcement plate 10 and the reinforcement plate 2 11 will overlap in the positioning plate 12 after flipping, so that the positioning plate 12 plays a certain positioning role in the flipping of the reinforcement plate 10 and the reinforcement plate 2 11, avoiding the information that the reinforcement plate 10 and the reinforcement plate 2 11 are misaligned when flipping.

[0023] like Figure 4 As shown, the sleeve plate 701 is fixedly connected to the bottom of the top plate 9, the multi-station tooth plate 703 is engaged with gear 1 704, the multi-station tooth plate 703 is engaged with gear 2 705, one end of the telescoping device 702 is connected to the auxiliary block 706, gear 1 704 is connected to one side of the reinforcement plate 10, and gear 2 705 is connected to one side of the reinforcement plate 2 11.

[0024] By setting the sleeve plate 701 and the multi-station tooth plate 703 to apply tension to the auxiliary block 706 through the telescopic device 702, the multi-station tooth plate 703 will slide in the sleeve plate 701 when subjected to tension. Since the multi-station tooth plate 703 is engaged with gear 1 704 and gear 2 705, the sleeve plate 701 plays a certain guiding role in the movement of the multi-station tooth plate 703, avoiding the multi-station tooth plate 703 from falling off during movement, and the positions of the tooth grooves on both sides of the multi-station tooth plate 703 are relative, so that the reinforcement plate 10 and the reinforcement plate 2 11 can realize the function of relative rotation. The reinforcement plate 10 and the reinforcement plate 2 11 can form a triangular shape when they are engaged after rotation, thereby ensuring the stability of the jacking structure.

[0025] The utility model provides a stable jacking structure, and the specific working principle is as follows:

[0026] When the jacking structure is in use, it will be operated by the two hydraulics 2 4 and the two hydraulics 1 3 in the base 1, and then the moving rod 2 6 will move in the hydraulics 2 4, and the moving rod 1 5 will move in the hydraulics 1 3. Since the two hydraulics 2 4 and the two hydraulics 1 3 are uniformly driven by the controller, the moving rod 1 5 and the moving rod 2 6 will move evenly, which can drive the top plate 9 to move above the base 1. When the height adjustment of the top plate 9 is completed, the telescopic device 70 2. When a pulling force is applied to the auxiliary block 706, the multi-station tooth plate 703 will slide in the sleeve plate 701 when subjected to the pulling force. Since the multi-station tooth plate 703 is meshed with the gear 1 704 and the gear 2 705, and the positions of the teeth and grooves on both sides of the multi-station tooth plate 703 are relative, the multi-station tooth plate 703 will drive the two reinforcement plates 2 11 in the moving rod 2 6 and the two reinforcement plates 1 10 in the moving rod 1 5 to rotate relative to each other after moving. The reinforcement plates 10 and 11 will be engaged in the positioning plate 12 when rotating.

[0027] After the reinforcement plate 1 10 and the reinforcement plate 2 11 are overlapped, the motor 803 drives the rotating plate 804 to rotate around the rotating rod 802. Since the rotating plate 804 is connected to the corresponding slide plate 805 through the connecting plate 806, the two slide plates 805 will move relative to each other in the auxiliary plate 801. When the two slide plates 805 move relative to each other, they will drive the limiting rod 807 to intersperse with the reinforcement plate 10 and the reinforcement plate 2 11, so that the reinforcement plate 10 and the reinforcement plate 2 11 can be fixed in the positioning plate 12.
