Taking the movable connection between the fork rod 9 and the second connecting frame 14 as an example: the sliding rod passes through the fork rod 9 and the second connecting frame 14 and then is welded to the anti-slip caps at both ends.

[0022] By setting the fork rod 9 and the motor 4 and other structures, the device can realize the lifting function. At the same time, since the fork rod 9 is connected by multiple groups of combined rods, the lifting range of the device is large, thereby increasing the scope of use of the device and increasing the practicality of the device.

[0023] Example 2, as Figure 2 、 Figure 4 As shown, a lifting device for installation and maintenance of electromechanical equipment, two groups of sliding frames 6 are welded to the lower end of the protective frame 1, a slide groove 7 is provided inside the sliding frame 6, and a limit ring 8 is provided on the front and rear sides of the sliding frame 6, a fork rod 9 is movably connected inside the sliding frame 6, the upper left end and the lower right end of the fork rod 9 are movably connected to the second connecting frame 14, the rear side of the fork rod 9 is movably connected to two groups of first connecting frames 12, a connecting pipe 13 and a hollow tube 3 are welded between the two groups of first connecting frames 12, the hollow tube 3 is sleeved on the outer wall of the connecting pipe 13, and the lower end of the connecting pipe 13 is threadedly connected to the limit cap 16.

[0024] By setting up structures such as the hollow tube 3 and the connecting tube 13, during the lifting process of the device, the cross direction of the fork rod 9 is limited by the hollow tube 3 and the connecting tube 13, and at the same time, the second connecting frame 14 is used to limit the two ends of the fork rod 9. The fork rod 9 can only slide in the sliding frame 6, which helps to improve the stability of the device during the lifting process and enhance the safety of the device.

[0025] It should be noted that the utility model is a lifting device for the installation and maintenance of electromechanical equipment. When in use, the motor 4 drives the transmission screw 10 to rotate, and the transmission screw 10 drives the movable frame 5 to move left and right, thereby changing the intersection angle of the fork rod 9.

The angle between the fork rod 9 and the second connecting frame 14 is changed, and the fork rod 9 slides in the slide groove 7. The limiting ring 8 prevents the fork rod 9 from falling out of the slide groove 7, so that the protective frame 1 can stably change the lifting height.
