Detailed Description

In order to further understand the structure, characteristics and other objects of the present invention, the following detailed description is given with reference to the accompanying preferred embodiments, which are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.

The reservoir water conduit groove backfill thickness limiting frame comprises a screening frame 6, an underframe 3 and a pulling device 18, wherein the pulling device is used for pulling the screening frame, four guide rods 4 are fixed at the top of the underframe, and the guide rods penetrate through round holes at the corners of the screening frame and are in clearance fit with the round holes;

the lifting device comprises two through shafts 7 and a driving shaft 10, wherein each through shaft is sleeved with two rope winding wheels 9 and fixed with the rope winding wheels, each rope winding wheel is wound with a pulling rope 1, the end part of the pulling rope is fixed on a hanging lug 15 of the screening frame, the end part of each through shaft is fixed with a worm wheel 8, and the worm wheel is meshed with a worm 12 on the driving shaft;
