[0025] like Figures 1 to 5 As shown in Embodiment 1: A lifting device for electromechanical installation in road and bridge construction includes: a lifting vehicle 3 connected to a U-shaped fence 1, the U-shaped fence 1 being rotatably connected to a protective door 2; a U-plate 6 connected to the lifting vehicle 3, the U-plate 6 being connected to a lower guide rod 7, and the U-plate 6 being bearing-connected to a main screw 5; an intermediate plate 8 connected to symmetrical lower sliders 22, the main screw 5 being threadedly connected to one of the lower sliders 22, the lower guide rod 7 passing through the other lower slider 22, and the intermediate plate 8 being connected to symmetrical upper U-shaped rods 9; and a support plate 10 connected to symmetrical upper sliders 18, the symmetrical upper U-shaped rods 9 passing through their respective upper sliders 18. The use of the support plate 10 facilitates the placement of the equipment. When the lifting vehicle 3 is raised to a preset position, the support plate 10 extends to facilitate the transfer of the equipment.

[0026] The intermediate plate 8 is connected to the intermediate shaft 23 and has a through groove 24. The center of the support plate 10 is connected to a long shaft 16, which is located within the through groove 24. The U-plate 6 is rotatably connected to one end of the first connecting rod 20. The intermediate shaft 23 is rotatably connected to the middle connecting rod 19, one end of which is rotatably connected to the other end of the first connecting rod 20. The long shaft 16 is rotatably connected to one end of the second connecting rod 17, and the other end of the middle connecting rod 19 is rotatably connected to the other end of the second connecting rod 17. By using a rotating connecting rod, the support plate 10 moves faster than the intermediate plate 8. The intermediate plate 8 provides protection and support, while the extended support plate 10 facilitates equipment removal.

[0027] The support plate 10 connects two sets of symmetrical guide rings 15, and the two vertical bars of the symmetrical spiral-shaped stop bar 14 pass through the corresponding guide rings 15. When the support plate 10 is retracted, the spiral-shaped stop bar 14 rises to protect the equipment.

[0028] The intermediate plate 8 is connected to the symmetrical square plate 21, and the symmetrical square plate 21 is respectively connected to the screw 13 by bearings. The symmetrical screw 13 is respectively connected to the corresponding spiral stop 14 by thread.

[0029] The symmetrical screws 13 are respectively connected to gears 12, and the U-plate 6 is connected to symmetrical racks 11. The symmetrical gears 12 mesh with the corresponding racks 11. By using gear and rack meshing, when the support plate 10 moves, the gears 12 rotate, driving the loop stop 14 to move along the guide ring 15.

[0030] The U-plate 6 is connected to the motor 4, and the output shaft of the motor 4 is connected to the main screw 5. By using the motor 4, power is provided for the movement of the support plate 10 and the intermediate plate 8.

[0031] The motor 4 is model Z4BLD.

[0032] The workflow of this embodiment is as follows:

[0033] When it is necessary to move the equipment, first use a crane or other means to place the equipment on the support plate 10. When it is necessary to move the equipment, manually pull the device or connect the device to a power trolley or other moving mechanism to move the device.

[0034] When it is necessary to remove this device to a designated height, operate the lifting vehicle 3 to raise the U-plate 6 to the appropriate height and open the protective door 2. Control the motor 4 to rotate, which drives the main screw 5 to rotate. The main screw 5 drives one lower slider 22 to move, which in turn drives the intermediate plate 8, the upper U-shaped rod 9, and the intermediate shaft 23 to move. The intermediate plate 8 drives another lower slider 22 to move along the lower guide rod 7. The intermediate shaft 23 drives the middle connecting rod 19 to swing, which in turn drives the first connecting rod 20 and the second connecting rod 17 to swing. The second connecting rod 17 drives the long shaft 16 to move along the through groove 24, which in turn drives the support plate 10 to move. The support plate 10 drives the upper slider 18 to move along the upper U-shaped rod 9. This causes the intermediate plate 8 and the support plate 10 to extend outward, so that the intermediate plate 8 blocks the gap between the lifting vehicle 3 and the height position. The support plate 10 drives the equipment to move outward, making it easier to remove the equipment.

[0035] Example 2: This example is a further elaboration based on Example 1.

[0036] The workflow of this embodiment is as follows:

[0037] When the support plate 10 moves the square plate 21, screw 13, gear 12, guide ring 15 and loop stop 14, the gear 12 meshes with the rack 11 and rotates. The gear 12 drives the screw 13 to rotate, and the screw 13 drives the loop stop 14 to move along the guide ring 15. When the support plate 10 is in the initial position, the loop stop 14 extends. When the support plate 10 extends, the loop stop 14 moves downward to facilitate the removal of the equipment.

[0038] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
