[0019] A method of using a lifting device with an automatic steering function for tunnel maintenance: When the device is specifically used, first carry the device to the working position, then push the support plate to move through the hydraulic rod, so that the support plate supports the device. Then, the staff stands in the guardrail and controls the electric slide rail to act through the operation button. At this time, the electric slide rail in the first guide plate drives the first guide plate to move through the slider, thereby performing a primary lift on the staff. Then, the electric slide rail in the second guide plate drives the lifting plate to move through the slider, thereby performing a secondary lift on the staff.

Then, the staff maintains the tunnel. During the maintenance process, when it is necessary to transport objects, control the electric rotation to reverse, so that the steel wire rope is released, and the object is fixed through the hook. Then, the electric slide rail rotates forward to wind up the steel wire rope, thereby hoisting the object to the lifting height. At this time, the staff opens the cover plate and can take down the object for use, ensuring the continuity and efficiency of the maintenance. And during the movement of the steel wire rope, the pulley guides it. When it is necessary to change the maintenance position, first drive the support plate to rise through the hydraulic rod, so that the electric wheel and the universal wheel contact the ground, and then drive the device to move through the electric wheel, and control its moving direction through the steering machine, so that the device can be quickly moved to the maintenance position without manual pushing of the device, which not only improves the flexibility of the device, but also reduces the working intensity of the staff.

[0022] 2. In the present invention, a hoisting mechanism composed of an electric rotating shaft, a steel wire rope, a pulley and a hook is designed. During maintenance, when it is necessary to transport an object, the electric rotation is controlled to reverse, so as to release the steel wire rope, and the object is fixed by the hook. Then the electric slide rail rotates forward to wind up the steel wire rope, and further hoist the object to the lifting height. At this time, the staff opens the cover plate, and then the object can be taken down for use, ensuring the continuity and efficiency of maintenance. And during the movement of the steel wire rope, the pulley guides it, improving the functionality of the device;

[0023] 3. In the present invention, an adsorption and fixing mechanism composed of an electromagnet and a magnetic plate is designed.
