Abstract
The utility model relates to a novel big stock of can buckling device belongs to the tunnel and struts technical field. The steel strand connecting rod comprises a steel strand rod body, a cylindrical connecting piece and a bonding filler, wherein the steel strand rod body and the cylindrical connecting piece are connected together through the bonding filler; the steel strand wires body of rod by have certain crooked flexible steel strand wires to make, cylindrical connecting piece includes hollow cylinder and the solid cylinder of screw thread, the hollow cylinder intussuseption is filled with and is cohered the filler and connect the steel strand wires body of rod, the solid cylinder of screw thread is equipped with the screw thread and is used for the mounting nut. The utility model has the advantages that: the structure is simple, and the cost is low; the rod body is made of steel stranded wires and has flexibility, and compared with a traditional anchor rod threaded steel rod body, the length of the traditional anchor rod threaded steel rod body is not limited by the size of a roadway; the tail end of the novel bendable anchor rod is provided with threads, so that a nut can be directly installed, the whole supporting speed is improved, and the cost is low; when the top coal is supported and tunneled in the dynamic pressure roadway, the problems that the top coal is thick, the anchor rod supporting effect is poor, the supporting speed by using the anchor cable is low and the cost is high can be solved.
Description
Technical Field
The utility model relates to a novel big stock of can buckling device belongs to the tunnel and struts technical field.
Background
With the further development of coal mines in China to the deep part, the problems of complex geological structures and high stress faced by roadway engineering are more and more prominent. When dynamic pressure roadway top coal supporting tunneling support is carried out, the top coal is often thicker, the traditional anchor rod support is used, the length of the anchor rod is limited, and the support effect is poor; if all the anchor cables are used for supporting, the mounting speed is low, the tunneling speed is seriously influenced, and the supporting cost is greatly increased. Under the background, the invention provides a novel bendable large anchor rod device.
Disclosure of Invention
In order to overcome the weak point of above-mentioned prior art, the utility model provides a novel big stock of buckling device is strutted at dynamic pressure tunnel back-up coal tunnelling and is used, because the body of rod uses is steel strand wires, length is unrestricted, and the connecting piece tail end can the snap-on nut, struts the speed and improves.
The utility model discloses a realize through following technical scheme: the utility model provides a novel big stock of can buckling device which characterized in that: the steel strand connecting rod comprises a steel strand rod body, a cylindrical connecting piece and a bonding filler, wherein the steel strand rod body and the cylindrical connecting piece are connected together through the bonding filler; the steel strand wires body of rod by have certain crooked flexible steel strand wires to make, cylindrical connecting piece includes hollow cylinder and the solid cylinder of screw thread, the hollow cylinder intussuseption is filled with and is cohered the filler and connect the steel strand wires body of rod, the solid cylinder of screw thread is equipped with the screw thread and is used for the mounting nut.
The length of the hollow cylinder of the cylindrical connecting piece is 10cm, the length of the thread solid cylinder is 10cm, and the diameter of the thread solid cylinder is the same as that of the steel strand rod body.
The utility model has the advantages that: the structure is simple, and the cost is low; the rod body is made of steel strands and has flexibility, and compared with a traditional anchor rod threaded steel rod body, the length of the anchor rod threaded steel rod body is not limited by the size of a roadway and can be longer; the tail end of the novel bendable anchor rod is provided with threads, so that a nut can be directly installed, the whole supporting speed is improved, and the cost is low; when the top coal is supported and tunneled in the dynamic pressure roadway, the problems that the top coal is thick, the anchor rod supporting effect is poor, the supporting speed by using the anchor cable is low and the cost is high can be solved.
Drawings
The invention will be further explained below with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of a cylindrical connecting member.
In the figure: 1. a steel strand rod body; 2. a cylindrical connecting member; 3. bonding a filler; 21. a hollow cylinder; 22. the thread is a solid cylinder.
Detailed Description
A novel bendable large anchor rod device as shown in fig. 1 to fig. 2, which is characterized in that: the steel strand connecting rod comprises a steel strand rod body 1, a cylindrical connecting piece 2 and a bonding filler 3, wherein the steel strand rod body 1 and the cylindrical connecting piece 2 are connected together through the bonding filler 3; the steel strand wires body of rod 1 by have certain crooked flexible steel strand wires to make, cylindrical connecting piece 2 includes hollow cylinder 21 and the solid cylinder 22 of screw thread, hollow cylinder 21 intussuseption is filled with and is cohered filler 3 and connect the steel strand wires body of rod 1, be equipped with the screw thread on the solid cylinder 22 of screw thread and be used for mounting nut.
The length of the hollow cylinder 21 of the cylindrical connecting piece 2 is 10cm, the length of the threaded solid cylinder 22 is 10cm, and the diameter of the threaded solid cylinder 22 is the same as that of the steel strand rod body 1.
The utility model discloses during the use: after drilling is finished, filling a resin anchoring agent, inserting the steel strand rod body 1, and stirring the resin anchoring agent; and (4) screwing the nut on the threaded solid cylinder 22 to apply pre-tightening force to the upper tray.
The installation is similar to a conventional anchor.
