The enlarged portion 110 being disposed adjacent and pressure release portion 130 are included, enlarged portion 110 is located at the first end of casing 10, the internal diameter of enlarged portion 110
More than the internal diameter in pressure release portion 130, enlarged portion 110 forms step 140 with 130 joint of pressure release portion；
Support portion 20, is set to the outer wall of casing 10, and support portion 20 to form supporting surface 210 along radially extending for casing 10；
The outer diameter of pressure release part 30, including gear 310 and the piston 320 that is fixedly connected with gear 310, gear 310 is more than set
The internal diameter in the pressure release portion 130 of pipe 10, the outer diameter of gear 310 no more than the enlarged portion 110 of casing 10 internal diameter, gear 310 it is complete
The tall and big radial dimension in step 140 of tooth, the outer diameter of piston 320 are adapted with the internal diameter in the pressure release portion of casing, and pressure release part 30 has
There is axially extending bore 330, when piston 320 is assemblied in pressure release portion 130, axially extending bore 330 is opposite with first through hole 120.
When in use, gear is located at the enlarged portion 110 of casing 10, piston dress to anchor cable unloader provided in an embodiment of the present invention
Assigned in pressure release portion, the cooperation that pressure release part can be stablized by piston with casing, when crushing, pressure reaches certain value
Afterwards, the inner wall in the teeth portion cutting casing pressure release portion 130 of gear generates resistance, and pressure release part carries out pressure release relative to cannula slide, prevents
Only pressure increases and breaks anchor cable suddenly.The setting of support portion 20 can carry out effective support to top plate.The configuration of the present invention is simple,
Easily operated, pressure release effect is good.
In the embodiment of the present invention, the center line of first through hole is overlapped with the axis in pressure release portion.It is arranged by each element coaxial,
It can make active force between the pressure release part of anchor cable unloader and casing evenly.Such as gear and piston are also coaxial arrangement.
As long as the gear in the embodiment of the present invention can cut internal surface of sleeve pipe in the case where reaching certain stress
Pressure release, therefore not more limitations.As a preferred embodiment, gear 310 is spline gear.
In the embodiment of the present invention, as long as the size of anchor cable unloader can meet its job requirement, other restrictions are had no.Below
It provides part preferred embodiment for reference and selects.Wherein, the radial dimension of step 140 is 3-5mm.The size of step 140 is determined
The maximum gauge for having determined gear cutting directly affects pressure release effect.The present embodiment can guarantee that gear smoothly cuts progress pressure release,
Pressure release will not be caused to fail soon very much because of gear sliding opposite with casing again.
As the preferred of above-described embodiment, the wall thickness in pressure release portion 130 is 10-12mm.The size can ensure that casing 10 has
There is enough intensity, and saves material as far as possible.
In addition, for other sizes, as long as equally disclosure satisfy that its job requirement, this is no longer going to repeat them.Example
Such as, the axial dimension of enlarged portion 110 can accommodate gear completely, also can partly accommodate.The axial dimension in pressure release portion 130 can root
It is determined according to different applicable cases.In addition, the anchor cable unloader of the embodiment of the present invention can there are many model, different model
Size is different, to be suitable for different situations.
In the embodiment of the present invention, support portion is mainly used for being supported top surface, therefore its concrete form is unlimited.Such as
It can also be interrupted that support portion can be continuous in the circumferential direction of casing.As a preferred embodiment, support portion 20
Continuous supporting surface is formed around the outer wall of casing 10.In addition, in order to improve the intensity of supporting surface, reinforcing rib can be set, it should
Reinforcing rib is set to the opposite face of supporting surface.The reinforcing rib can be plate reinforcing rib, the plate reinforcing rib simultaneously with support portion and
Casing connection, the plate reinforcing rib are vertical with the axis of casing.The support effect of plate reinforcing rib is good.
In the embodiment of the present invention, the second end of casing preferably protrudes from support portion, is positioned when in order to use.As
A kind of preferred, support zone is in the lower part of casing.In this way, can there are enough parts to be positioned.As a further preference,
The length of the casing 10 of 20 top of support portion is at least the half of 10 total length of casing.The present embodiment can improve use
When stability.
Gear and piston in the embodiment of the present invention can be directly connected to can also be to be indirectly connected with by connector.Make
Preferably for one of those, gear 310 is fixedly connected with piston 320 by connector sleeve 340.It can be with by using connector 340
Piston is set to stretch into inside pipe casing, the cooperation of pressure release part and casing is more stablized.
In embodiment as shown in the figure, casing 20 is cylinder, and other shapes are not precluded certainly.Equally, support portion is outer
The shape of profile is also not limited, and can is rectangle as shown in the figure, be can also be the other shapes such as circle.
The use process of the anchor cable unloader of the embodiment of the present invention is briefly described below, in order to further understand
The present invention.
It has openning hole on top plate, in order to which the upper end of casing 10 to be assemblied in the hole, support portion 20 holds top plate
Support.Pressure release part is assembled on casing 10, piston is assemblied in pressure release portion 130, and gear is assemblied in enlarged portion 110.Anchor cable is by first
Through-hole 120 and axially extending bore 330 pass through anchor cable unloader, and anchor cable tool is packed on anchor cable, is tightened to specified pulling force.Collapse when under top plate
When, top plate is applied to the increase of the power on support portion 20, and pressure release part 30 is relatively fixed in the traction down space position of anchor cable, therefore,
Interaction force (between gear 310 and step 140) increases between pressure release part 30 and casing 10, when reaching design function power
Afterwards, the teeth portion of gear 310 cuts the inner wall (inner wall in pressure release portion) of casing, generates resistance, pressure release part is relative to casing
Sliding carries out pressure release, prevents pressure from increasing suddenly and breaking anchor cable.
