Problems solved by technology

If the pulling force is large, the pressure between the lock head and the wall of the through hole will increase geometrically, and the wire rope may come out due to the fragmentation of the tapered lock head.

Embodiment Construction

[0012] figure 1 As shown, a step-type strong anchor cable device includes: a cylindrical main body 1, and an annular groove 2 is arranged on the main body 1, and the annular groove 2 is coaxial with the main body 1.

[0013] An expansion ring 3 is provided in the ring groove 2, and a lock pin 3a is arranged on the expansion ring 3. When the expansion ring 3 is not drawn out with the lock pin 3a, the diameter of the expansion ring 3 is the same as that of the main body 1. When the lock After the pin 3a is pulled out from the expansion ring 3, the diameter of the expansion ring 3 becomes larger, exceeding the diameter of the main body 1.

[0014] A through hole 1a is arranged in the axial direction on the main body 1, and a steel wire rope 5 is threaded through the through hole. An annular notch 4a distributed in a step shape, and the annular notch 4a is coaxial with the tapered lock head 4.

[0015] One end of the through hole 1a is provided with a set of enlarged parts 1b co...

Abstract

The invention provides a step type strong anchor cable device. The step type strong anchor cable device comprises a body (1). Ring grooves (2) are formed in the body (1). Expansion rings (3) are arranged in the ring grooves (2). Lock pins (3a) are arranged on the expansion rings (3). A through hole (1a) is formed in the body (1) the axial direction. A steel wire rope (5) is arranged in the through hole in a penetrating manner. A lock head (4) is arranged at one end of the steel wire rope (5). The step type strong anchor cable device is characterized in that an annular notch (4a) is formed in the lock head (4), and an expanding part (1b) correspondingly matched with the annular notch (4a) is arranged at one end of the through hole (1a). The step type strong anchor cable device is simple in structure, convenient to use and capable of effectively improving the use intensity of an anchor cable and enlarging the application range of the anchor cable.

Description

Technical field: [0001] The invention provides a fixing device, specifically a stepped strong anchor cable device. Background technique: [0002] The anchor cable in the project is fixed on the slope surface through the outer end, and the other end is anchored in the stable rock mass within the sliding surface of the rock mass. The prestressed steel strand passing through the sliding surface of the rock mass slope, by applying prestress, directly Generate anti-sliding resistance on the sliding surface, increase the anti-sliding frictional resistance, and make the structural surface in a forced compaction state, so as to improve the integrity of the rock mass of the slope, thereby fundamentally improving the mechanical properties of the rock mass and effectively controlling The relative displacement of the rock mass promotes its stability and achieves the purpose of controlling bedding, landslides and dangerous rocks and dangerous rocks. [0003] When the anchor cables in th...
