Description
Technical field
The utility model relates to anchor rod drawing measure test field, in particular to it is a kind of for exposed anchor rod drawing test
Levelling device.
Background technique
When side slope, country rock or underground engineering, which are needed, need to carry out pull-out test with exposed anchor pole, due to because of gunite concrete
Lead to the out-of-flatness of field basic face or rockbolt installation angle difference and is difficult to that anchor rod drawing instrument is installed, even if reluctantly after installation,
Since the pulling force that base surface out-of-flatness causes anchor pole to receive is uneven, thus the examination of the anchor rod drawing displacement measured and pulling capacity
Data inaccuracy is tested, this can cause serious influence to engineering.And the pull-out test main purpose of anchor pole is exactly to ensure engineering
Quality prevents the phenomenon that using inferior materials and turning out substandard goods, therefore in the case where base surface out-of-flatness or different rockbolt installation angle, how to assist
Drawing instrument is installed, realizes that the axis of the exposed anchor pole of any angle can be vertical with the plane that drawing instrument is installed, and can be carried out
Accurate pull-out test is very required.
Also the installation of monitoring device is related in current open source literature and protects related content, such as application No. is
200920103326.1 Chinese patent, discloses a kind of anchor rod strength test device, and specially a kind of anchor rod drawing instrument solves
The problems such as stress generally existing in anchor rod drawing is unbalance, anchor pole protruded length deficiency causes test difficulty to increase, wherein
The first power transmission backing plate, the second power transmission backing plate and third power transmission backing plate belong to the anchor rod drawing instrument, be not independent device, and
When being not directed to base surface out-of-flatness or rockbolt installation angle difference, how to adjust drawing instrument makes the mounting plane and anchor pole of drawing instrument
The vertical problem of axis.
For another example application No. is 201310285757.5 Chinese patents, a kind of anchor rod drawing backing plate are disclosed, by plastic cement material
Material is made, and backing plate is the rectangular parallelepiped structure of four identical end feets of band, which can reduce anchor rod drawing test period
And cost, the anchor pole shorter to reserved part also can be carried out test, are not directed to and are difficult to pacify because rockbolt installation angle is different
The problem of filling anchor rod drawing instrument.
For another example application No. is 201620558210.7 Chinese patents, disclose a kind of anchor rod drawing test hydraulic pressure support dress
It sets, drawing instrument equipment anchor pole and jack in installation and drawing process is made on the same axis, to make to be displaced amesdial and anchor pole
Be not in sliding, during the test since the intensity of anchoring body will lead to jack more than range, be more than after range by
In the non-adjustable height of support, cause must cushioning block can just make test continue, be not directed to installation drawing instrument base surface
Out-of-flatness or rockbolt installation angle are different and be difficult to the problems such as installing anchor rod drawing instrument, and the mounting plane for being less related to drawing instrument can
The problem of adjustment.
