the respective symbols in the figure are as follows: 1 flat bolt fastener, 2 flexible stands, 3 position control spare, 301 sleeve pipes, 302 slide rails, 3021 spout, 303 flexible pipe, 4 stopper, 5 string bags.

Detailed Description

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The invention will be further explained with reference to the drawings.

As shown in fig. 1 to 4, the material fixing clamp special for tower operation provided by the invention comprises a plain end bolt wire clamp 1, a telescopic upright post 2, a position adjusting piece 3, a net bag 5 and two plug-in type limiting blocks 4 which are connected in sequence. The telescopic upright post is a buckle type, pipe-rotating type or external-rotating type telescopic rod and can be quickly fixed after being pulled out. The string bag is used for placing tools.

The position adjusting piece comprises a strip-shaped sliding rail 302, the upper surface and the lower surface of the strip-shaped sliding rail are respectively provided with a sliding groove 3021 with an upward opening and a downward opening, two telescopic pipes 303 are arranged above the sliding rail, two sleeves 301 are arranged below the sliding rail, the telescopic pipes and the sleeves freely slide in the sliding rail, and a limiting block is detachably connected to the sliding groove above the limiting block and used for fixing the positions of the telescopic pipes.

The telescopic pipes are buckle type telescopic rods with two ends capable of being pulled, and the two opposite sides of the net bag are respectively fixed on the two telescopic pipes and can be stretched or unfolded along with the relative sliding of the two telescopic pipes. The free ends of the two sleeves are respectively detachably connected to the top ends of the two telescopic stand columns; the telescopic upright posts are connected with the sleeve through bolts, so that the position adjusting part and the two telescopic upright posts can be assembled quickly at high altitude. The iron tower structure surface facing the slope, two flexible stands, through the flexible degree of difference, make the slide rail of top keep the level to keep the string bag opening level that stretches out, avoid the instrument to drop.

When the device works, the two plain bolt wire clamps clamp the iron tower, and the telescopic upright column above the iron tower is adjusted to enable the top end of the telescopic upright column to be stretched to a horizontal position. And then adjusting the distance between the two sleeves, and fixing the sleeves at the top ends of the telescopic vertical columns by bolts respectively. The two extension tubes are pulled open and fixed by a limiting block. The telescopic pipe is pulled open and fixed according to the space size, and the net bag is pulled open at the moment. When the work is finished, the whole clamp is disassembled and recovered.

It should be understood that the above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and equivalents may be made in the technical solutions described in the foregoing embodiments, or some technical features may be substituted. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
