The application discloses a wood floor cutting device and a use method thereof and belongs to the technical field of floor measuring and cutting. The wood floor cutting device comprises a base, an L-shaped ruler, a floor fixing mechanism, a cutting disc driving mechanism and an auxiliary plate limiting mechanism. The base is fixedly connected with the L-shaped ruler. The upper surface of the inside of the base is provided with an L-shaped groove. The bottom end of the auxiliary plate is rotationally connected with the top of the connecting column of the connecting piece. The bottom of the connecting column is fixed with a circular sliding block. The circular sliding block is slidingly connected in the L-shaped groove. The bottom of the auxiliary plate is connected with the cutting disc driving mechanism. The auxiliary plate and the L-shaped ruler are connected through the auxiliary plate limiting mechanism. The inner wall of the base is further connected with the floor fixing mechanism. The L-shaped ruler and the L-shaped groove are arranged. The movable and slidable auxiliary plate structure is matched. The cutting disc driving mechanism can be moved and positioned in two directions perpendicular to each other. The accurate cutting of the length and the width of the wood floor can be sequentially completed without re-clamping the floor.

The application belongs to the technical field of wood processing tools and discloses a wood multidirectional cutting guide plate with a positioning scale, which comprises a guide plate main body, a mounting groove is formed in the side surface of the guide plate main body, and a ruler is inserted and mounted in the mounting groove. The positioning protrusion of the positioning column cooperates with the positioning gap in the convex column positioning groove, can be directly clamped into the gap corresponding to the preset angle, and mechanical positioning is realized. This structure does not need manual repeated measurement, controls the angle error in the mechanical tolerance range, can quickly switch various cutting angles, solves the problem of the traditional mode of "depending on experience and large error", cooperates with the length positioning of the ruler, can complete straight line cutting, can realize 45° bevel cutting, arbitrary angle mortise and tenon cutting and the like, covers the diversified needs of furniture manufacturing, decoration and the like scenes, breaks through the limitation of the traditional guide plate "single function", meanwhile, the plug-in connection of the positioning column and the positioning groove limits rotation, the magnet adsorption cutting platform prevents translation.

This utility model discloses a device for controlling the top elevation of a bored pile, including a bored pile hole. A grouting pipe is inserted into the inner side of the bored pile hole. A support positioning plate body is sleeved on the outer surface of the grouting pipe. The support positioning plate body adopts a folded plate structure and is fixed to the outer surface of the reinforcing cage around the bored pile hole. A floating measuring scale rod is slidably inserted into the inner surface of the support positioning plate body. An annular support float body is fixedly connected to the lower surface of the floating measuring scale rod. The outer surface of the floating measuring scale rod is provided with scale lines. The annular support float body structure is set in a large area inside the bored pile hole. The floating measuring scale rod on its surface measures the grouting depth. Its floating support area is large, which is more accurate. Moreover, the detachable sliding lifting structure is more accurate and the structure is solid.

A height measuring device for work roll guard plates in heavy plate rolling mills, belonging to the technical field of rolling mill maintenance tools, is used to measure the height of work roll guard plates in heavy plate rolling mills. The technical solution is as follows: a ruler frame is a rectangular plate with a sliding groove at one end, perpendicular to the length direction of the frame; a scale is a rectangular plate with a width matching the width of the sliding groove, embedded in the sliding groove; the frame surface outside the sliding groove has frame graduation lines, and the scale surface has scale lines opposite to the frame graduation lines; a bar-type level is fixed to the upper surface of the rectangular plate of the frame, with its length direction along the length direction of the frame. This utility model has a simple structure and is easy to use, enabling accurate measurement of the height of work roll guard plates in rolling mills, shortening inspection time, improving inspection efficiency, and reducing the labor intensity of workers.
