Description
Technical field
It the utility model is related to a kind of anchor pole high pre-stress hydraulic tensioning device, more particularly to a kind of multi-cylinder anchor rod hydraulic
Drawing device.
Background technology
As development of resources and underground engineering construction gradually develop from superficial part to deep, lane（Tunnel）The deeps such as road, chamber
The geomechanics environment of lower engineering institute preservation becomes more for complexity, and the deformation of country rock is also universal larger, or even occurrence of large-area emits
Push up, be caving, rolling over the catastrophic failures such as side, under this hard situation, anchor pole high pre-stress hydraulic tensioning technology is deep underground
The stability control of engineering surrounding rock provides a kind of effective approach, and has obtained relatively broad application at home.Anchor pole is high
The dominant mechanism that prestressing stretching technique is controlled the large deformation of deep engineering country rock is higher pre- by applying to high strength anchor bar
Clamp force, and then promote country rock to be in pressured state, improve the stress distribution of country rock, protect the complete of anchorage zone country rock to greatest extent
Whole property, improves the bulk strength and stability of country rock, and suppresses the deformation of the discontinuities such as anchorage zone country rock flexure, absciss layer, slip
Destroy.The defects of existing anchor rod hydraulic tensioning equipment, is：Tensioning cylinder body is merely able to carry out anchor pole perpendicular to tunnel palisades
Tensioning, when anchor pole axial direction and tunnel palisades（Wall）When non-perpendicular, cause stretching force axially inconsistent with anchor pole, not only influence anchor
The effect of bar tensioning, but also anchor rod body may be damaged.And existing anchor rod hydraulic tensioning equipment only has a hydraulic cylinder
Body, the suspension roof support for large-tonnage, it is difficult to play tensioning effect.In addition, after anchor pole tensioning, anchor nut inconvenience is tightened, and is lacked
Weary a kind of easy to operate and higher efficiency fastening means.To ensure the stabilization of the fastening of nut and whole device, it is badly in need of one
Kind easy to operate and higher efficiency nut fastening method and device.
Chinese patent ZL200420112695.4 discloses a kind of big-tonnage multi-cylinder type anchor cable stretching tool, can provide compared with
Big stretching force carries out prestressing force loading to anchor cable, however, it can not be directly used in the tensioning of anchor pole, this is due to anchor cable
It for flexible anchoring device, can bend, the diameter parallel of tensioning direction and anchor cable not needed during tensioning, you can realize of anchor cable

When be also possible to damage anchor rod body.And tensioning direction and the bolt shaft for causing tensioner are not addressed how in the Chinese patent
The problem of line is consistent, the technical scheme of problem is also tightened without inconvenience when providing solution anchor nut tensioning.
Chinese patent ZL 201620558210.7 discloses a kind of anchor rod drawing experiment hydraulic support device, upper bearing plate
Supported by multiple hydraulic support devices, the bottom of the hydraulic pressure support bar of hydraulic support device is hinged on down by spherical hinge structure holds
On pressing plate.The technical problem that the device solves be ensure anchor rod drawing during anchor pole axis and jack in same axis
On, however, the support meanss are in use, anchor pole is not suitable for under the operating mode of palisades out of plumb, being suitable only for pouring
Build under the not vertical operating mode of anchor pole caused by the out-of-flatness in face.Under palisades inclination conditions, due to the bottom of hydraulic pressure support bar
It is hinged on by spherical hinge structure on lower bearing plate, while bearing plate on causing is vertical with anchor pole, hydraulic pressure support can be filled
The axis put has certain angle with pulling capacity, in drawing process, bearing plate can be caused to be in non-equilibrium state, generation pair
The shearing force of anchor pole, damage anchor pole.Moreover, the technical scheme is a support meanss, still drawn using a jack
Pull out.
