Preferably, the length of safe spacing cylinder is 5th/4th to six/5ths of protection cylinder length.
Preferably, positioning sleeve is spring steel or Copper alloy material structure.
Preferably, nut plug is steel alloy material-structure.
Preferably, protection cylinder is coating steel pipe structure.
The beneficial effects of the utility model：
1. simple in construction firm, anti-impact force is strong, and crashworthiness is good, durable use.
2. component is few, each component can realize standardization batch production, and cost is low, and assembly technology is simple, is hardly damaged, and reduce
Maintenance management cost.
3. being easy to the termination of more steel wire ropes being fastenedly connected on guardrail frame, substitute traditional expansion bolt and be fastenedly connected
Mode, effectively avoid steel wire rope fixing end failure phenomenon from occurring, prevent wire cable rupture accident, eliminate guardrail rack Zona transformans and come
Potential safety hazard.
4. safe spacing cylinder can slide in protection cylinder, and in the over-stressed pulling of steel wire rope, steel wire rope pulls double end
Stud, studs drive nut plug extruding safe spacing cylinder, safe spacing cylinder stress deformation and snubber energy, are steel
While cord provides safe spacing, it can effectively prevent excessive load from causing steel wire rope fixing end failure even steel wire rope to break
The accident split occurs, and reduces guardrail rack and deform the potential safety hazard such as impaired.
Brief description of the drawings
It is intended to be easy to describe preferred embodiment in conjunction with the following drawings, does not form the limit to scope of protection of the utility model
System.
Fig. 1 is the structural representation that the utility model is assemblied on guardrail rack.
In figure：1- bitter end anchorages, 2- safety caging devices, 3- anchorage bodies, 4- positioning sleeves, the spacing anchor slabs of 5-, 6- are worn
Hole, 7- grooves, 8- centre bores, 9- studs, 10- protection cylinders, 11- safe spacing cylinders, 12- nut plugs.
Embodiment
In order to facilitate the utility model is understood, below in conjunction with the accompanying drawings in the preferred embodiment pair of the present utility model that provides
The utility model is described in detail.
The utility model steel wire rope end head as shown in Figure 1 fixes anchorage, including bitter end anchorage 1 and safety caging device 2,
Safety caging device 2 is fixed on guardrail rack.Bitter end anchorage 1 includes anchorage body 3, positioning sleeve 4 and spacing anchor slab 5, anchorage sheet
Body 3 is in cylinder, the uniform some perforation 6 being used for through steel wire rope of annular vertically of anchorage body 3, perforate 6 rear portion aperture
The formula of extending out offers the groove 7 for rabbeting positioning sleeve 4, and positioning sleeve 4 is that spring steel or Copper alloy material structure, steel wire rope are worn
The swelling of positioning sleeve 4 is crossed to be fixed on groove 7.The rear portion of anchorage body 3 is provided with the centre bore 8 of internal thread.Safe spacing fills
Putting 2 includes protection cylinder 10, safe spacing cylinder 11, nut plug 12 and studs 9, and protection cylinder 10 uses coating steel pipe structure,
