It is truncated.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
A kind of device for preventing that anchor cable is truncated, including prevent cutting sleeve pipe, prevent that cutting sleeve pipe includes reinforced pipe and pad, pad
Center is provided with circular hole, and the top of circular hole is connected with reinforced pipe；Anti- sleeve pipe of cutting is enclosed on anchor cable with the contact position of anchor cable pallet, adding
The internal diameter of strong pipe is more than the external diameter of anchor cable, and the external diameter of reinforced pipe is less than the round mouth internal diameter of anchor cable pallet.
Preferably, the lower section of the pad is provided with lockset, and lockset is set in outside anchor cable, pad is fixed on anchor cable pallet
On.
It is further preferred that the length of the pad is more than or equal to the diameter of lockset.
Preferably, the external diameter of the reinforced pipe is less than or equal to the diameter of circular hole.
Preferably, the reinforced pipe is welded on the top of circular hole.
Preferably, the pad is iron plate.
Preferably, the reinforced pipe is iron pipe or steel pipe.
Compared with prior art, the utility model has technique effect beneficial below：
A kind of device for preventing that anchor cable is truncated provided by the utility model, pass through the contact position in anchor cable with anchor cable pallet
The place of putting, which is set, to be prevented cutting sleeve pipe, the cross shear that anchor cable pallet can be avoided to apply directly to anchor cable, is born so as to increase anchor cable
Shearing force, prevent anchor cable to be truncated.The utility model compared with prior art, has that process is simple, easy to process, material comes
Source is wide, cost is low；Occupy little space, be in light weight, be easy for installation, be simple in construction, be reasonable in design；Anti-shear ability is strong, anti-to block
Significant effect, the advantages of supporting intensity is high.Can meet all kinds of wells () under tunnel cable bolting requirement, effectively prevent anchor
The phenomenon that rope is blocked failure by shearing force occurs, and cost of implementation is low, has a wide range of application.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1-4, the utility model provides a kind of device for preventing anchor cable to be truncated, including prevents cutting sleeve pipe 3, anti-to cut
Sleeve pipe 3 includes reinforced pipe 8 and pad 7, and the center of pad 7 is provided with circular hole, and the top of circular hole is connected with reinforced pipe 8；It is anti-to cut sleeve pipe 3
It is enclosed on anchor cable 1 and at the contact position of anchor cable pallet 4, the internal diameter of reinforced pipe 8 is more than the external diameter of anchor cable 1, the external diameter of reinforced pipe 8 is small
In the round mouth internal diameter of anchor cable pallet 4.
Preferably, the lower section of the pad 7 is provided with lockset 2, and lockset 2 is set in outside anchor cable 1, pad 7 is fixed on anchor cable
