Brief description of the drawings
Fig. 1 is inclination angle type opening size test device sectional schematic diagram.
Fig. 2 is inclination angle type opening size test device top view.
In figure：Center-pole 1, extend radially out beam 2, stretch out beam adjustable section 3, bolt 4, diagonal brace 5, the adaptive bar in aperture
6th, pulley 7, torsionspring 8.
Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, a kind of inclination angle type opening size test device, the device are used for rotary digging, drilling and impact holing stake
Detected along depth direction pore size.Test device includes center-pole 1, extends radially out beam 2, stretches out beam adjustable section 3, positioning spiral shell
Bolt 4, the adaptive bar 6 in aperture, pulley 7, torsionspring 8.Overhung construction of the center-pole 1 as whole device, its top can connect
Lifting rope, installation site of the inner hollow as electrical equipments such as roll sensor and circuits, waterproof can be achieved after cavities seals
Function.The bottom of center-pole 1 is arranged to tip, and bottom sediment is may be inserted into when device sinks down into bottom hole, is realized to bottom part aperture diameter
Measurement.
It is symmetrically fixed with the circumference of center-pole 1 some to extending radially out beam 2.Two pairs are shown in Fig. 2, but according to actual feelings
Condition can be set more.Two beam bodies that each pair is extended radially out in beam 2 are respectively arranged in the both sides of center-pole 1, and two beams are protected
Hold on the same line.Every extends radially out beam 2 and one end of center-pole 1 is provided with stretching beam adjustable section 3, and stretching out beam can
Multiple positioning holes are provided with along bearing of trend in regulation section 3 and the beam body for extending radially out beam 2.Both positions can be adjusted
Put, and pass through the distance between bolt 4 and the end of cooperation adjustment stretching beam adjustable section 3 of positioning hole and center-pole 1.Aperture
Adaptive bar 6 is one and is articulated with the straight-bar stretched out on the end of beam adjustable section 3, and both hinge points are provided with torsionspring
8.Incline sensor and end of survey is carried on the adaptive bar 6 in aperture pulley 7 is set.Pretightning force on torsionspring 8 causes aperture certainly
Bar 6 is adapted to when being rotated to vertical direction, it can be applied and extend out power, whole device is kept during being slided up and down in hole
It is close to hole wall in pulley-type.Thus, according to the geometrical length between each body of rod, with reference to surveying, the aperture that the sensor that inclines measures is adaptive
The angle of bar 6 and center-pole 1, you can the diameter of pore-forming is calculated.
In order to improve the structural strength for extending radially out beam 2, diagonal brace 5 can be set between center-pole 1 at it.Whole test dress
The center of gravity put is located on the axis of center-pole 1, and lifting rope installation is with the axis, process is being moved up and down with holding meanss
In, extend radially out beam 2 and stretch out the keep level state as far as possible of beam adjustable section 3.
The method that pore-forming opening size test is carried out based on said apparatus, is comprised the following steps：
Step 1：It is adjusted to stretching out beam adjustable section 3, its end is kept certain distance with pore-forming hole wall, and pass through
Bolt 4 is fixed, and pulley 7 is peaked at all the time on hole wall in sliding process in pore-forming.
Step 2：Opening size test device is transferred by lifting rope vertically until bottom hole, now the bottom of center-pole 1 is commonly inserted
In bottom hole scum layer.
Step 3：After pore-forming bottom hole is reached, opening size test device is above carried by lifting rope and is kept as far as possible during upper carry
The beam 2 that extends radially out of opening size test device is horizontal；During above carrying, the adaptive bar in different depth position aperture is recorded
6 and the inclination value of center-pole 1, convert to obtain pore size data by geometrical relationship.During being somebody's turn to do, it can incline what sensor measured by surveying
Depth residing for data corresponding intrument is stored, and is subsequently converted again, data can also be passed through into the reality that wirelessly or non-wirelessly communicates
When transmit to ground, pass through data processing equipment carry out in real time record and show.
Step 4：After the completion of test, test device is proposed into pore-forming, and is cleared up and is safeguarded, to treat to use next time.
Embodiment described above is a kind of preferable scheme of the present utility model, so itself and be not used to limit this practicality
It is new.Those of ordinary skill about technical field, can be with the case where not departing from spirit and scope of the present utility model
Make a variety of changes and modification.Therefore the technical scheme that all modes for taking equivalent substitution or equivalent transformation are obtained, all falls within
In the scope of protection of the utility model.
