Description
Technical field
The utility model relates to anchor cable locks, and in particular to a kind of oblique pull anchor cable lock.
Background technique
Currently, being frequently encountered in national coal industry underground tunneling roadway work progress, top plate interlamellar spacing is thin or tunnel
Fillet position shear pressure is big, needs to take oblique pull anchor cable hanging girder steel or single-point oblique pull anchor cable to reinforce branch in Special zone
Shield；Lockset used at present often will appear anchor cable from lockset root tensile phenomenon, this is because making in the actual operation process
With oblique pull anchor cable reuse ordinary lock rise tension and compression it is tight when, cause anchor cable in its lockset root discontinuity to generating change
Shape, anchor cable have received cross shear, and in stress, shearing force, which is gradually increased, causes anchor cable to be broken in lockset root, thus
Lead to a large amount of wastes of support material and effective supporting effect can not be played to back.
Summary of the invention
The utility model is to solve existing ordinary lock to make oblique pull anchor cable in supporting, and the root of anchor cable is by Transverse Shear
Shear force effect is easy the technical issues of breaking, and provides a kind of oblique pull anchor cable lock, anchor cable root is avoided to be acted on by cross shear,
Guarantee the support action of anchor cable.
In order to solve the above technical problems, the technology employed by the present utility model is a kind of oblique pull anchor cable lock, including
Matching used upper lockset and lower lockset, the ontology of the upper lockset are hollow cylinder, and an end face of hollow cylinder
It is processed into inclined-plane, the angle between the beveled end and other end is 15 ° -25 °；The ontology of the lower lockset is cylindrical body,
One end of the cylindrical body is connected with round estrade, and the round estrade is consistent with the diameter for the end face that cylindrical body is in contact, institute
State one end that round estrade is not in contact with cylindrical body end face diameter be less than cylindrical body end face diameter, the lower lockset it is interior
Portion offers the cavity of truncated cone-shaped, and the lock core to match with cavity geometry is provided in the cavity of the truncated cone-shaped；The rotary table
The end face diameter of one end that body is not in contact with cylindrical body is less than the internal diameter of upper lockset, one end that round estrade is in contact with cylindrical body
End face diameter be less than upper lockset internal diameter.
For above-mentioned lockset in use, upper lockset and lower lockset are set in the root of oblique pull anchor cable, upper lockset is located at lower lockset
Top, the beveled end of upper lockset with by supporting face contact, the hollow cavity for stretching to lockset of the rotary table body portion of lower lockset
In vivo, due to round estrade in the hollow cavity of upper lockset can rotation by a small margin, it is effective to control anchor cable angle, make anchor cable
It is able to maintain in stress consistent with the compression direction of lockset, has been effectively prevented the cross shear that anchor cable is subject to, ensure that
The intensity of anchor cable ensures that the validity of tunnel anchor cable/rod supporting.
Compared with prior art the utility model has the following beneficial effects:
The utility model oblique pull anchor cable lock can be controlled effectively by the round estrade of lower lockset and the scarf of upper lockset
Anchor cable angle processed is able to maintain anchor cable in stress consistent with the compression direction of lockset, has been effectively prevented what anchor cable was subject to
Cross shear ensure that the intensity of anchor cable, ensure that the validity of tunnel anchor cable/rod supporting.

Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of oblique pull anchor cable lock, including matching used upper lockset 1 and lower lockset 2, the upper lockset 1
Ontology be hollow cylinder, and inclined-plane is processed into an end face of hollow cylinder, between the beveled end and other end
Angle be 15 °；The ontology of the lower lockset 2 is cylindrical body, and an end of the cylindrical body is connected with round estrade 3, described
Round estrade 3 is consistent with the diameter for the end face that cylindrical body is in contact, the end face of one end that the round estrade 3 is not in contact with cylindrical body
Diameter is less than the diameter of the end face of cylindrical body, and the inside of the lower lockset 2 offers the cavity of truncated cone-shaped, the sky of the truncated cone-shaped
It is intracavitary to be provided with the lock core to match with cavity geometry；The end face diameter of one end that the round estrade 3 is not in contact with cylindrical body
Less than the internal diameter of upper lockset 1, the end face diameter of one end that round estrade 3 is in contact with cylindrical body is less than the internal diameter of upper lockset 1.
Further, the upper lockset 1 and lower lockset 2 are made of stainless steel material.
Angle between 1 beveled end of upper lockset and other end can also be 20 °.
