Description

A kind of anchor rod drawing test hydraulic support device
Technical field
This utility model is a kind of anchor rod drawing test hydraulic support device, belongs to anchor rod drawing test field.
Background technology
When carrying out anchor rod drawing test, generally use pre-designed bearing plate and carry out installation test device, no Assay device can be changed, such as when the experimental site poured in advance is tested, owing to pouring face along with the environment of experiment Out-of-flatness can cause the anchor pole can not be vertical, offset.Can offset when utilizing amesdial to gather data, thus cause Experimental data is inaccurate.In experimentation, the adhesion strength between anchoring body and country rock body is high, causes anchor pole in drawing Cheng Zhonghui surrenders, and elastic plastic strain occurs, causes displacement excessive, after exceeding the range of jack, due to the height of pressure-bearing platform Can not change and cause test not proceed, only after adding cushion block, then continue in the range ability of jack after release Carry out, but too big due to pulling capacity in test, and common brick is when cushion block comprcssive strength is not by during applying power Cushion block is crushed.Furthermore during installing anchor pole, owing to bearing plate is that overall must passing from anchor pole top is installed, Installing trouble, early stage installment work bothers, and later stage work amount is big, and test accuracy is the highest.So, a kind of simple quick installation of design Anchor rod drawing assay device has realistic meaning.
Utility model content
For meeting the requirement of existing experimental condition, this utility model provides a kind of anchor rod drawing test hydraulic support device, Equipment anchor pole and jack in installation and drawing process is made on the same axis, to make displacement amesdial and anchor pole not have cunning Move.This device is simple to operate, can effectively improve work efficiency.
In order to solve above-mentioned technical problem, the utility model proposes techniques below scheme: a kind of anchor rod drawing tests hydraulic pressure Support means, it includes that bearing plate, the upper surface of described upper bearing plate are provided with circular horizontal instrument, the end of described upper bearing plate Portion is provided with three hydraulic support devices, is hinged on down by spherical hinge structure bottom the hydraulic pressure support bar of described hydraulic support device On bearing plate, described upper bearing plate is equilateral triangle, and the center of upper bearing plate is provided with manhole.
Described spherical hinge structure includes being arranged at the bulb bottom hydraulic pressure support bar, described bulb be arranged on lower bearing plate Ball groove match.
Described upper bearing plate uses split type structure, and it includes left-half and right panel part, described left-half and the right side Plate part assembles and forms equilateral triangle, and three angles of described equilateral triangle are arc-shaped, and described two halves part is bolted It is connected.
The top of described hydraulic pressure support bar is welded and fixed by the lower end surface of welding with upper bearing plate.
Described upper bearing plate uses steel plate materials to make.
This utility model has the advantages that:
Utilize this device, make equipment anchor pole and jack in installation and drawing process on the same axis, make displacement thousand Point table and anchor pole do not have sliding, simultaneously by upper bearing plate use package assembly can make during anchor pole is installed without Make assay device must be passed by anchor pole top, anchor pole can be made by upper bearing plate center by package assembly, then lead to Cross bolt and connect two steel plates.Jack can be caused to exceed range due to the intensity of anchoring body in process of the test, exceed range After due to the non-adjustable height of bearing, cause adding cushion block and test just can be made to proceed, the hydraulic system utilizing this device can To solve this problem, regulation bearing height, proceed test after pressure release.This device alleviates labor intensity, improves adjustment Efficiency, improve Adjustment precision, Adjustment effect is good, conveniently moving, simple in construction.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As Figure 1-5, a kind of anchor rod drawing test hydraulic support device, it is characterised in that: include bearing plate 1, on Being provided with circular horizontal instrument 2 on bearing plate 1, upper bearing plate 1 is positioned on three hydraulic support devices 3, the end of hydraulic pressure support bar 4 Portion is connected to lower bearing plate 5 by ball-joint structure, and described upper bearing plate 1 is equilateral triangle, and the heart of above bearing plate 1 is circle The heart arranges manhole 6.
Preferably, described hydraulic cylinder welds with upper bearing plate 1, and described upper bearing plate 1 is designed as equilateral triangle and three Dihedral heart goes out to arrange circular duct, and upper bearing plate 1 uses can load and unload design.
Preferably, described upper bearing plate 1 uses split type structure, and it includes left-half 101 and right panel part 102, institute Stating left-half 101 and right panel part 102 assembles and forms equilateral triangle, three angles of described equilateral triangle are arc-shaped, described Two halves part is fixedly linked by bolt 9.
Preferably, described ball-joint structure includes that the bulb 7 being designed at liquid presses piston pole 4 end is in designing at lower bearing plate Ball groove 8 on 5, bulb 7 is connected with ball groove 8 simultaneously.
Preferably, bulb 7 and ball groove 8 design can make lower bearing plate 5 movable, can be adjusted according to the difference of contact surface.
Preferably, in process of the test, the bonding strength between anchoring body and country rock body is big, reaches range at jack Shi Wei extracts, for avoiding artificially increasing cushion block, can be by regulation of hydraulic system bearing height, and at the beginning of pressure release makes jack recover Begin, be further continued for test.
