[0027] Example 1: Please refer to Figure 1-Figure 4 A lifting device for construction engineering comprises a base 1, a support frame 2 is fixedly installed on the top of the base 1, two groups of the support frames 2 are provided, and a moving frame 3 for transporting plates is slidably installed in the gap between the two groups, a flip plate 4 for assisting the plates to rotate and stand upright is rotatably installed on the upper surface of the moving frame 3, a rotating structure for controlling the flip plate 4 to flip is fixedly installed inside the moving frame 3, a fixed structure for adsorbing and fixing a limit is fixedly installed on one side of the flip plate 4, a lifting structure for adjusting the up and down movement of the plates is fixedly installed inside the base 1, and a universal wheel for facilitating the movement of the entire device is fixedly installed at the bottom end of the base 1;

[0028] The rotating structure includes a fixed plate 5, which is fixedly mounted on the inner wall of the moving frame 3 and is used to assist in limiting the rotation of the flip plate 4. A main control bar 501 is rotatably mounted on a side of the fixed plate 5 away from the moving frame 3. A connecting shaft 502 is rotatably connected to the inside of one end of the main control bar 501. A rotating bar 503 is rotatably mounted on the outer surface of the connecting shaft 502. A flip frame 504 for driving the flip plate 4 to rotate is rotatably mounted on one side of the rotating bar 503. The flip frame 504 is fixedly connected to the outer surface of the flip plate 4 at one end away from the rotating bar 503 through bolts.

[0029] Specifically, a moving shaft 505 for assisting the movement of the turning frame 504 is fixedly installed inside the turning frame 504. There are two groups of turning frames 504 in total and they are symmetrically and evenly distributed. A connecting rod 506 is rotatably installed on one side corresponding to the two groups of turning frames 504, and both ends of the connecting rod 506 pass through the inside of the rotating bar 503 and the turning frame 504. An arc groove for providing movement of the connecting rod 506 and a straight groove for providing up and down movement of the moving shaft 505 are opened inside the fixed plate 5, and one end of the connecting rod 506 and the moving shaft 505 are respectively located in the arc groove and the straight groove;

[0030] More specifically, the main control bar 501 rotates with one end away from the connecting shaft 502 as a fixed point, driving the connecting shaft 502 to pull the rotating bar 503 to rotate, driving the connecting rod 506 to connect the flip frame 504 with the end close to the rotating bar 503 with the moving shaft 505 as the top, and rotating and moving along the arc groove, so that the connecting rod 506 moves into the straight groove, and the main control bar 501 continues to rotate, so that the connecting rod 506 and the moving shaft 505 move along the straight groove in turn, and then drive the flip frame 504 to connect the flip plate 4 to rotate at an angle, so as to adjust the flip plate 4 to a horizontal or vertical state, so as to facilitate the construction personnel to place or remove the plate. When the flip plate 4 is in a horizontal state, it is convenient for the fixed structure to adsorb and position the plate. After the moving frame 3 is flipped as a whole, it can also play a role as a bottom support for the plate. When the flip plate 4 is in a vertical state, it provides a stable vertical support for the plate, so that the construction personnel can remove the plate more easily and conveniently.

[0031] A dual-axis motor 507 for providing rotational power to the main control bar 501 is fixedly installed inside the moving frame 3. Rotating shafts 508 are fixedly installed on the output ends on both sides of the dual-axis motor 507, and one end of the two sets of rotating shafts 508 are fixedly connected to the main control bar 501. The main control bar 501 is driven to rotate by connecting the rotating shafts 508 to the output ends of the dual-axis motor 507.

[0032] See also Figure 5 An auxiliary structure for assisting the flipping of the flipping plate 4 is fixedly installed on one side of the flipping plate 4, and the auxiliary structure includes a gear disc 509, and the gear disc 509 is fixedly installed on the outer surface of the rotating shaft 508. A gear disc 2 510 is meshed on one side of the gear disc 509, and a rotating plate 511 is fixedly installed on one side of the gear disc 510. A pushing plate 512 for pushing and supporting the flipping plate 4 is rotatably installed on one side of the rotating plate 511, and one end of the pushing plate 512 is rotatably connected to the outer wall of the flipping plate 4; specifically, the gear disc 2 510 and the pushing plate 512 are respectively connected to the moving frame 3 and the flipping plate 4 through connecting pieces rotatably installed on both sides thereof. Two groups of auxiliary structures are provided, which play a role in dispersing the force points and ensuring that the flipping operation of the flipping plate 4 is performed at a uniform and stable speed.

[0033] See also Figure 6The fixed structure includes an air pump 6, which is fixedly installed on one side of the flip plate 4. A plurality of suction cups 601 for adsorbing and positioning the plate are fixedly installed on the other side of the flip plate 4. A plurality of air pipes 602 for controlling the operation of the suction cups 601 are fixedly installed on both sides of the air pump 6, and the positions of each group of air pipes 602 and the suction cups 601 correspond to each other.

[0034] See also Figure 7 A top plate 7 is movably installed at the upper end of the base 1 for driving the plate to move up and approach the suction cup 601. An electric rod 701 is fixedly installed at the bottom end of the top plate 7, and the electric rod 701 is located inside the base 1. The electric rod 701 pushes the top plate 7 to drive the plate to approach the suction cup 601, so as to assist the suction cup 601 in adsorbing and positioning the plate. Multiple groups of plates can be stacked on the top plate 7 to achieve the effect of automatic adsorption, effectively avoiding the gap between the suction cup 601 and the plate due to a reduction in the number of plates or a change in the thickness of the plate itself, which affects the effect of the device in limiting the position of the plate.

[0035] Example 2: Please refer to Figure 7-Figure 8 The lifting structure includes a threaded rod 8, the threaded rod 8 is located in the support frame 2, the outer wall of the threaded rod 8 is threadedly sleeved with a lifting block 801, and the lifting block 801 is rotatably connected to the outer surface of the moving frame 3, and the bottom end of the threaded rod 8 is fixedly installed with a driving structure for controlling the rotation of the threaded rod 8;

[0036] The driving structure includes a double-axis motor 802, which is located inside the base 1 and is mainly used to provide rotational power for the threaded rod 8. The output ends of both sides of the double-axis motor 802 are fixedly installed with rotating rods 803, and one side of the rotating rod 803 is fixedly installed with a bevel gear 1 804. The outer wall of one side of the bevel gear 1 804 is meshed with a bevel gear 2 805 for driving the threaded rod 8 to rotate, and the bevel gear 2 805 is fixedly installed at the bottom end of the threaded rod 8.

[0037] Specifically, the dual-axis motor 802 is connected to the rotating rod 803 to drive the bevel gear 1 804 and the bevel gear 2 805 to control the rotation of the threaded rod 8, and then connected to the lifting block 801 to drive the moving frame 3 to adjust the lifting height of the plate;

[0038] Limiting rods 806 for assisting the lifting of the moving frame 3 are fixedly installed on both sides of the moving frame 3 close to the supporting frame 2. The limiting rods 806 extend to the inside of the supporting frame 2. A moving groove for providing movement of the limiting rods 806 is provided inside the supporting frame 2. A limiting plate for limiting the movement range of the limiting rods 806 is fixedly installed inside the moving groove.

[0039] Specifically, one end of the limit rod 806 away from the moving frame 3 is set as a rolling ball to facilitate movement in the moving groove. The limit rods 806 are set in two groups, and two groups are set symmetrically and evenly distributed on both sides of the moving frame 3. The limit plates are set in one group, and two groups are set symmetrically and evenly distributed in the two groups of support frames 2. Only one of the two limit rods 806 in one group contacts the limit plate, so that when the lifting block 801 is connected to the moving frame 3 to drive the limit rod 806 to move in the moving groove, it contacts the limit plate, and one limit rod 806 is blocked and cannot move further downward, so that another limit rod 806 drives the moving frame 3 to flip over with the lifting block 801 as the fixed point, so that the moving frame 3 moves downward and flips, allowing the suction cup 601 to approach the plate placed on the upper surface of the top plate 7, reducing the workload of manpower in moving the plate. Conversely, after the moving frame 3 moves up and flips, the suction cup 601 drives the plate upward, and the moving frame 3 provides bottom support for the plate, avoiding shaking of the plate, reducing safety hazards, and preventing the plate from falling, which facilitates the operation of the subsequent rotating structure.

[0040] The working principle of the utility model is:

[0041] First, place multiple groups of plates on the top of the top plate 7, start the electric rod 701 to push the top plate 7 to drive the plates close to the suction cup 601, let the air pump 6 connect to the air pipe 602 to control the suction cup 601 to absorb and position the plates, then start the dual-axis motor 802 to connect the rotating rod 803 to drive the bevel gear 1 804 and the bevel gear 2 805 to control the threaded rod 8 to rotate, and let the lifting block 801 drive the moving frame 3 and the plates to move upward. In this process, when the moving frame 3 is connected to the limit rod 806 to move in the moving groove, one limit rod 806 is blocked by the limit plate and cannot continue to move downward, so that the other limit rod 806 drives the moving frame 3 to flip with the lifting block 801 as the fixed point, so that the suction cup 601 Drive the plate upward to provide bottom support for the plate; the threaded rod 8 continues to rotate, connecting the lifting block 801 to drive the moving frame 3 and the plate to move up to a suitable height, and then start the dual-axis motor 507 to connect the rotating shaft 508 to drive the main control bar 501 to rotate, and pull the rotating bar 503 through the connecting shaft 502 to drive the connecting rod 506 connected to the flip frame 504 to rotate and move, so that the flip plate 4 rotates at an angle, and at the same time, the rotating shaft 508 is connected to the gear plate 1 509 to drive the gear plate 2 510 to control the rotating plate 511 and the pushing plate 512 to push the flip plate 4 to rotate at a uniform speed, so that it is perpendicular to the moving frame 3, thereby controlling the plate to be in an upright state, which is convenient for removing the plate.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
