CONTENT OF UTILITY MODEL

[0003] To solve the above problems, the utility model discloses a concentric positioning device for filling and plugging material in sleeve, adopts mechanical device control filling material concentric uniform construction, simple structure, convenient construction can improve quality, improve the yield, reduce cost.

[0004] To achieve the above object, the technical scheme of the utility model is as follows:

[0005] A concentric positioning device for filling and plugging material in sleeve, including the adjustable screw rod of the clamping that can open and close, the clamping that can open and close is hollow cylinder (or tubular), the clamping that can open and close is combined by two semicircular metal sheets, four groups of convex bolt walls (with internal thread) are evenly arranged on the outer wall of the clamping that can open and close, the convex bolt wall is communicated with the clamping that can open and close, and the adjustable screw rod is screwed into the convex bolt wall from the outer end.

[0006] As an improvement of the utility model, one end of the two semicircular metal sheets is connected through a hinge, the other end is provided with an extended edge strip, and the two edge strips are connected through bolts.

[0007] As an improvement of the utility model, the length of the adjustable screw rod is greater than the length of the convex bolt wall.

[0008] As an improvement of the utility model, each group of convex bolt walls is composed of three convex bolt walls, and the three convex bolt walls are arranged from top to bottom.

[0009] As an improvement of the utility model, the four groups of convex bolt walls are arranged in the shape of cross, and the positions of the hinge and the edge strip are staggered.

[0010] The utility model has the advantages of:

[0011] The utility model discloses a concentric positioning device for filling and plugging material in sleeve, adopt adjustable bolt and make the inner tube center, thereby control filling material concentric even construction, simple structure, can dismantle and reuse, convenient construction, can improve quality, promote yield, reduce cost.

[0017] The utility model is further illustrated below in combination with the drawings and specific embodiments, and it should be understood that the following specific embodiments are only used for illustrating the utility model and not for limiting the scope of the utility model.

[0018] As shown in the figure, the concentric positioning device for filling and plugging material in sleeve of the utility model, its structure includes can open and close the hoop 1 and adjusting screw 2, the can open and close the hoop 1 is hollow cylinder (or tubular), the can open and close the hoop 1 is combined by two semicircular metal plates 4, the can open and close the hoop 1 outer side wall is evenly provided with four groups of convex bolt wall (has internal thread), and each group of convex bolt wall is composed of three convex bolt walls 2, the three convex bolt walls 2 are arranged from top to bottom, the convex bolt wall 2 is communicated with the can open and close the hoop 1, and the adjusting screw 3 is screwed into the convex bolt wall 2 from the outer end, and the length of the adjusting screw 3 is greater than the length of the convex bolt wall 2.

[0019] The can open and close the hoop 1 of the device is provided with three rows of adjusting screws 2 on the outer side vertically, and four are located in the east, west, south and north directions in each row.After the pre-buried pipe construction is completed, the inner tube construction is carried out, the inner tube is inserted into the pre-buried pipe, the device is wrapped around the pre-buried pipe and the inner tube, the middle and lower row screws are adjusted and fixed in the pre-buried pipe wall, and then the upper row screw is adjusted to make the inner tube fixed in the center.After the device is fixed at the two ends of the pre-buried sleeve, the filling and plugging material is filled.Adjusting bolt is used to make the inner tube center, thereby controlling the concentric and even construction of the filling material, and the structure is simple, convenient for construction, can improve the quality and improve the yield.

[0020] The both semicircular metal plates 4 are connected through the hinge 6 at one end, and are provided with the outer extension of the edge strip 7 at the other end, and the both edge strips 7 are connected through the bolt 5 at the position, and can be repeatedly used after being disassembled, and the cost is reduced.

[0021] The four groups of convex bolt walls are arranged in the "cross" type, and the positions of the hinge 6 and the edge strip 7 are staggered.

[0022] It should be noted that the above content only illustrates the technical idea of the utility model, and cannot limit the protection scope of the utility model, and for the ordinary skilled in the art, some improvements and decorations can be made without departing from the principle of the utility model, and the improvements and decorations all fall within the protection scope of the utility model claim.
