Description

Technical Field

[0002] During the earthwork construction process, excavators are used to dig in sections. After the excavation is completed, the slope is leveled and the surface of the slope is leveled to prevent protrusions and loose soil. After the leveling is completed, the slope is positioned and laid out according to the design drawings. After the pre-process of the foundation pit is completed, the laying process of the concrete canvas will begin. The laying process will adopt a crane + manual operation method. The crane is used to adjust the coil to the top of the slope, and then the crane slowly lays the canvas along the slope to make the concrete canvas evenly spread on the slope to ensure the fit between the canvas and the slope. When hoisting the coil, it is more troublesome to connect the unwinding rod with bolts. When unwinding, the contact between the wire rope and the coil is easy to wear the coil, and the unwinding rod cannot rotate, resulting in poor unwinding smoothness of the coil. Therefore, we designed a concrete canvas laying device. The unwinding rod supporting the coil can rotate by itself to increase the smoothness of unwinding, and it is connected to the unwinding rod to avoid twisting the bolts. The installation efficiency is high, the laying efficiency is improved, the coil is in contact with the guard plate, and the coil is avoided. Damage to the coil. Utility Model Content

One end of the limit cover 9 is provided with a sleeve groove 10 adapted to the limit convex strip 14, and one side of the inner cavity of the limit cover 9 is fixedly connected with a rubber plug 11, and the surface of the rubber plug 11 is fitted to the inner wall of the unwinding long tube 1, and the side of the limit cover 9 close to the unwinding long tube 1 is fitted with the limit convex strip 25. Through the setting of the limit cover 9, the rubber plug 11 on the limit cover 9 is inserted into the inner cavity of the unwinding long tube 1, and the limit cover 9 is fixed to the surface of the unwinding long tube 1 by friction. The limit cover 9 can cover the limit convex strip 14 and abut against the limit convex strip 25 to prevent the connecting sleeve 6 from moving outward. Movement, both ends of the surface of the unwinding long tube 1 are sleeved with connecting blocks 6, and a side protective plate 12 sleeved on the surface of the unwinding long tube 1 is arranged between the connecting block 6 and the concrete canvas coil 3. The top and bottom of the inner cavity of the side protective plate 12 are provided with a limiting cavity 13 adapted to the limiting convex strip 25, and the top and bottom of the inner cavity of the connecting block 6 are provided with a limiting cavity 7 adapted to the limiting convex strip 14 and the limiting convex strip 25. The top of the connecting block 6 is provided with a connecting component 8 connected to the wire rope, and the connecting component 8 includes a A U-shaped strip 82 is arranged on the surface of the connecting sleeve 6, a fixing ring 83 is welded to one end of the U-shaped strip 82, a bolt 85 is welded to the other end of the U-shaped strip 82, a bolt 85 is passed through the inner cavity of the fixing ring 83, one end of the bolt 85 passes through the through hole 81 and is threadedly connected to the threaded sleeve 84.

The arc-shaped U-shaped strip 82 contacts the wire rope, which reduces the friction of the wire rope contact, protects the wire rope, and prolongs the service life of the wire rope.

[0025] Working principle: When the utility model is used, the steel wire rope is connected to the connecting sleeve block 6 through the connecting assembly 8, the unwinding long tube 1 is passed through the concrete canvas coil 3, the side protection plate 12 is picked up, so that the limiting concave cavity 2 13 on the side protection plate 12 passes through the limiting convex strip 1 4, and then rotated ninety degrees, so that the limiting concave cavity 2 13 is sleeved on the surface of the limiting convex strip 2 5 for limiting, and then the connecting sleeve block 6 is picked up, so that the limiting concave cavity 1 7 is sleeved on the surface of the limiting convex strip 2 5 like the limiting concave cavity 2 13, Then, put the limit cover 9 on the end of the unwinding long tube 1 and press it against the limit convex strip 25. When unwinding, the crane lifts the concrete canvas coil 3 through the unwinding long tube 1. During the unwinding process of the concrete canvas coil 3, the rotating outer tube 2 is driven to rotate on the surface of the unwinding long tube 1, which increases the smoothness of unwinding.

[0026] In summary, the concrete canvas laying device is constructed by inserting the unwinding long tube 1 on the coiled material, and then sequentially putting the side protection plates 12 and the connecting sleeve 6 on the surfaces of the limiting convex strips 2 5 at both ends of the surface of the unwinding long tube 1. Since the limiting convex strips 2 5 are misaligned with the limiting convex strips 1 4, the connecting sleeve 6 will not be easily separated from the surface of the unwinding long tube 1. The limiting cover 9 is installed on the limiting connecting sleeve 6 and slides outward. The crane cooperates with manual labor to unwind the concrete canvas coiled material 3 on the surface of the unwinding long tube 1. The rotation of the rotating outer tube 2 increases the smoothness of unwinding. The side protection plates 12 can prevent the coiled material from contacting and being damaged by the connecting sleeve 6. The unwinding rod supporting the coil can rotate by itself, which increases the smoothness of unwinding. The sleeve is connected to the unwinding rod to avoid tightening the bolts, with high installation efficiency and improved laying efficiency. The coil is in contact with the guard plate to avoid damage to the coil. The problem of using a crane to adjust the coil to the top of the slope protection, and then the crane slowly lays the canvas down along the slope, so that the concrete canvas is evenly spread on the slope to ensure the fit between the canvas and the slope. When hoisting the coil, it is more troublesome to connect the unwinding rod with bolts. When unwinding, the wire rope contacts the coil and easily wears the coil. The unwinding rod cannot rotate, resulting in poor smoothness of unwinding the coil.
