Abstract
The utility model relates to a press knot formula flexible stock, including cable wire (1), press knot (4) and heart ring (3), cable wire (1) middle part 180 degrees of bending form flexion fag end (2), the size of flexion fag end (2) and the external dimension phase-match of heart ring (3), place in flexion fag end (2) heart ring (3), the closed department in both ends of cable wire (1) that constitutes flexion fag end (2) is provided with presses knot (4). The utility model discloses when receiving the pulling force of protection network, can not like shaft-like stock sled stratum, make the anchor eye receive axial and radial power to make the stratum fracture, influence the firm of stock, but outwards drag along the anchor eye, consequently the difficult fracture in anchor eye and stratum, the stock is more firm. And the structure is simple, the production cost is saved, and the fastening speed is accelerated.
Description
Technical Field
The utility model relates to a protection network anchor technical field, especially a formula flexible stock is detained to pressure.
Background
The anchor rod is a device for reinforcing the main body of a mine hole, a roadway, a side slope, a tunnel and a dam body at present, one end of the anchor rod is deeply buried in the stratum, and the other end of the anchor rod is connected with an engineering structure. The general anchor rod in the market is rod-shaped, and the rod-shaped anchor rod is buried in the stratum and then grouted into the buried hole, and the anchor rod and the stratum are connected into a whole in a grouting mode. However, when the rod-shaped anchor rod is connected with the protective net, the rod-shaped anchor rod needs to be connected and fixed through the steel cable, the steel cable is difficult to be connected with the rod-shaped anchor rod, even if the connection and the fixation are successful, the length of the steel cable connected between the protective net and the rod-shaped anchor rod is very long, the swing range of the protective net taking the rod-shaped anchor rod as the center of a circle is large, and the protective net is. And the connecting process between the connecting steel cable and the rod-shaped anchor rod is complex and difficult, and the fastening efficiency of the protective net is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide one kind and be convenient for be connected with the protection network to can reduce the flexible stock of protection network and fastening point distance.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a title flexible stock of pressure knot formula, includes the cable wire, presses knot and heart ring, the 180 degrees crooked formation flexion noose in cable wire middle part, the size of flexion noose and the external dimension phase-match of heart ring, the heart ring is placed in the flexion noose, the both ends closed department of the cable wire that constitutes the flexion noose is provided with the pressure knot.
The outer side surface of the heart ring is an inwards concave arc-shaped surface. The arc surface is matched with the arc surface of the steel cable forming the rope sleeve of the bending part, so that the heart ring is prevented from falling off from the rope sleeve of the bending part.
The pressing buckle is an integrated 3-shaped structure formed by pressing a metal sheet. After the pressing and buckling die is pressed on the closed positions of the two ends of the steel cable forming the rope sling of the bending part, the steel cable forming the rope sling of the bending part cannot be opened due to the 8-shaped structure of the section, and the steel cable is formed by pressing through the pressing die, so that the looseness condition cannot occur.
The lengths of the rope sleeves from the two ends of the steel rope to the bending part are the same.
The utility model has the advantages of it is following:
1. by adopting a novel pressing buckle fastening structure, the fastening effect is achieved, the diameter of a steel rope fastening point is reduced, the blocking of an anchor hole is reduced in site construction, and the grouting efficiency and quality are improved;
2. the flexible anchor rod has a heart-shaped steel cable sleeve, so that the fastening speed of the engineering structure connected with the flexible anchor rod can be increased; meanwhile, the production efficiency is improved, and the production labor intensity is reduced;
3. when the flexible anchor rod receives the pulling force of the protective net, the stratum can not be pried like a rod-shaped anchor rod, so that the anchor hole receives axial and radial force, the stratum is cracked, the stability of the anchor rod is influenced, the anchor hole is outwards pulled, the anchor hole and the stratum are not easy to crack, and the anchor rod is more stable.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a cross-sectional view taken at A-A of FIG. 1;
in the figure: 1-steel cable, 2-bending part rope sleeve, 3-heart ring and 4-press button.
Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1, the flexible anchor rod comprises a steel cable 1, a press buckle 4 and a heart ring 3, wherein the middle of the steel cable 1 is bent by 180 degrees to form a bending part rope sleeve 2, the size of the bending part rope sleeve 2 is matched with the external size of the heart ring 3, the heart ring 3 is placed in the bending part rope sleeve 2, and the press buckle 4 is arranged at the closed position of two ends of the steel cable 1 forming the bending part rope sleeve 2.
The outer side surface of the chicken heart ring 3 is an inwards concave arc-shaped surface. The arc surface is matched with the arc surface of the steel cable 1 forming the rope sling 2 of the bending part, so that the heart ring 3 is prevented from falling off from the rope sling 2 of the bending part.
The pressing buckle 4 is of an integrated 3-shaped structure formed by pressing a metal sheet. After the pressing buckle 4 is pressed on the closed positions of the two ends of the steel cable 1 forming the rope sleeve 2 of the bending part by a mould, the steel cable 1 forming the rope sleeve 2 of the bending part cannot be opened due to the 8-shaped structure of the section, and the steel cable is formed by pressing through a pressing mould, so that the looseness can not occur.
The lengths of the rope sleeves 2 from the two ends of the steel rope 1 to the bending part are the same.
The working process of the utility model is as follows: drilling an anchor hole through a drilling machine, inserting one end of the rope sling 2 without the bending part into the anchor hole, leaving the rope sling 2 with the bending part on the ground, grouting into the anchor hole, and fixing the part of the anchor rod inserted into the anchor hole in the stratum. After the grouting is finished, the protective net and the bent rope sleeve 2 are connected into a whole through the fastener, the steel cable 1 or the anchor ear, and the bent rope sleeve 2 and the protective net are made of the steel cable 1, so that the protective net can be directly fastened together and cannot slip off, and the process is simple and rapid. When the flexible anchor rod receives the pulling force of the protective net, the stratum can not be pried like a rod-shaped anchor rod, so that the anchor hole receives axial and radial force, the stratum is cracked, the stability of the anchor rod is influenced, the anchor hole is outwards pulled, the anchor hole and the stratum are not easy to crack, and the anchor rod is more stable.
