[0002] Drainage ditches refer to ditches that direct water collected in side ditches, intercepting ditches, near roadbeds, in farmlands, and in low-lying areas near houses to outside the roadbeds, farmlands, and houses. Drainage ditches usually have covers installed on their surfaces to cover the top and prevent objects from falling into the ditch and causing blockage.

Therefore, in order to facilitate the transportation and installation of drain covers, people have invented a lifting device for drain covers. Public literature also reports some lifting devices for drain covers, such as:

[0009] Through applied research, it is found that most cement covers are currently transported to the construction site by transport vehicles, and then the cement covers are hoisted and unloaded by the crane on the transport vehicle, stacked at a certain distance, and then the stacked ditch covers are installed one by one. However, the above-mentioned public documents 1-3 have a relatively complex structure and are not easy to operate, and are not suitable for hoisting and installing the stacked ditch covers one by one; documents 4 and 5 require manpower to control the lifting and lowering of the ditch covers, which has high labor intensity, and the lowering height is not easy to control, which is easy to cause the side ditch to collapse and fall off during the installation process, and there are great safety hazards. Therefore, it is necessary to design a lifting and installation device that can lift and install the stacked ditch covers one by one. Summary of the invention
