Abstract
The anchor cable secondary protection device of the utility model, it includes: casing, cushion, connection iron wire and tie wire, the anchor cable secondary protection device is fixed on the lower end of the anchor cable in tunnel, anchor net is fixed on tunnel surface, metal gasket and anchorage are sequentially arranged with stretching out on anchor cable from tunnel, the lower end of the anchor cable is in casing, cushion is housed between anchor cable and casing, the one end for connecting iron wire passes through the bottom end of casing, the both ends of connection iron wire are fixed on that anchor is online, are fixed with tie wire on two connection iron wires above casing；The utility model fundamentally solves the problems, such as that anchor cable is hurted sb.'s feelings.
Description
Technical field
The utility model relates to a kind of anchor cable secondary protection devices, it is mainly used for the tunnel of cable bolting, to anchor cable
Stretching end anchorage and backing plate caused by being broken fall and pound people, and anchor cable head steel twist wire alters that silk is hurted sb.'s feelings and anchor cable head scrapes the feelings such as hurt sb.'s feelings
Condition has specific aim protection effect.
Background technique
Coal mine well lane engineering is to improve drivage efficiency, mostly uses bolt-mesh-anchor support mode greatly, anchor cable by prestress wire,
Backing plate, anchorage (fixture), four part of Anchor Agent are composed, after tunnel pick branch, by crustal stress, tectonic stress, mining influence, lane
Road surrouding rock stress is unevenly distributed, and local stress is more concentrated, when and occur anchor cable steel strand wires fracture, alter silk, anchorage downslide slip
Phenomena such as, security risk will be constituted to the pedestrian in on-site personnel or tunnel；In addition, its anchor cable head of the low level anchor cable of construction
Exist to operating personnel and pedestrian and scrapes scuffing hidden danger.In recent years, a lot of such casualty accidents had occurred in succession for many mines.
Currently, stretching end caused by the fracture of cable bolting tunnel steel strand wires falls and alters, the full hidden danger that silk is hurted sb.'s feelings only is accomplished
Different types of passive protection, not yet inherently solves.
Summary of the invention
Present invention purpose is to solve the problems, such as that anchor cable is hurted sb.'s feelings, and provides a kind of anchor cable secondary protection device.
In order to complete present invention purpose, the application uses following technical scheme:
A kind of anchor cable secondary protection device of the utility model, it includes: casing, cushion, connection iron wire and binding iron
Silk, the anchor cable secondary protection device are fixed on the lower end of the anchor cable in tunnel, are fixed with anchor net on tunnel surface, stretch from tunnel
Metal gasket and anchorage are sequentially arranged on anchor cable out, in which: the lower end of the anchor cable fills between anchor cable and casing in casing
There is cushion, the one end for connecting iron wire passes through the bottom end of casing, and connecting the both ends of iron wire, to be fixed on anchor online, above casing
Tie wire is fixed on two connection iron wires；
A kind of anchor cable secondary protection device of the utility model, in which: described sleeve pipe is polyethylene pipe；
A kind of anchor cable secondary protection device of the utility model, in which: the cushion is batten or nylon rod；
A kind of anchor cable secondary protection device of the utility model, in which: the connection iron wire is bifilar iron wire；
A kind of anchor cable secondary protection device of the utility model, in which: the tie wire is bifilar iron wire.
Compared with prior art, the utility model anchor cable secondary protection device has the advantage that
(1), anchor cable head causes people's casualty accident to happen occasionally, and analyzes its feature of hurting sb.'s feelings, and mainly has pad caused by anchor cable fracture
Plate and lockset, which fall, pounds people, and anchor cable head steel twist wire alters that silk is hurted sb.'s feelings and anchor cable head scrapes situations such as hurting sb.'s feelings, outside supporting anchorage cable
Feature and feature of hurting sb.'s feelings, take specific aim safeguard procedures.
(2), using φ 32mm, wall thickness 4mm underground with polyethylene pipe sleeve on φ 21.8mm anchor cable head, solve anchor cable head
Scrape scuffing hidden danger；
(3), the cushion (hard round log item or nylon rod) of 21~23mm of φ, the bifilar 12# in lower end are installed additional in pipe sleeve
Iron wire support can effectively solve anchor cable head and alter silk and hurts sb.'s feelings hidden danger；
(4), two side anchor net (steel mesh) of anchor cable backing plate is symmetrically connected to after bifilar 12# iron wire being passed through one stomidium of casing
On, can effectively solving stretching end (anchorage, metal caul) caused by anchor cable steel strand wires are broken, falling injures personnel by a crashing object.
Detailed description of the invention

Diagrammatic cross-section.
In Fig. 1, label 1 is connection iron wire；Label 2 is tie wire；Label 3 is casing；Label 4 is cushion；Mark
Numbers 5 be anchorage；Label 6 is tunnel；Label 7 is anchor cable；Label 8 is metal gasket；Label 9 is anchor net.
Specific embodiment
As shown in Figure 1, the utility model anchor cable secondary protection device includes: casing 3, cushion 4, connection iron wire 1 and ties up
Wire-tie 2, the anchor cable secondary protection device are fixed on the lower end of the anchor cable 7 in tunnel 6, are fixed with anchor net 9 on 6 surface of tunnel,
It is sequentially arranged with metal gasket 8 and anchorage 5 stretching out on anchor cable 7 from tunnel 6, the lower end of anchor cable 7 is in casing 3, in anchor cable 7 and set
Cushion 4 is housed, one end of connection iron wire 1 passes through the bottom end of casing 3, and the both ends of connection iron wire 1 are fixed on anchor net 9 between pipe 3
On, tie wire 2 is fixed on two connection iron wires 1 above casing 3.
Casing 3 is polyethylene pipe；Cushion 4 is batten or nylon rod.Connection iron wire 1 is bifilar iron wire.Tie wire 2 is
Bifilar iron wire.
Embodiment described above is only that the preferred embodiment of the utility model patent is described, not to this
The range of utility model patent is defined, and under the premise of not departing from the utility model patent design spirit, this field is common
The various changes and improvements that technical staff makes the technical solution of the utility model patent should all fall into the utility model patent
Protection scope in.
