Background technology
Road surface coring operation is to use road surface core drilling rig（Drill bit of drilling machine diameter is generally φ 100 or φ 150）Constructing
Scene drills through representative core sample, is used for the Inspection of Thickness in each layer work progress in road surface and the inspection of engineering IMM algorithm, because
The integrality of this core sample is most important for the result of inspection, and how by the core sample being drilled through core drilling machine intactly from drilling
Take out, and keep the complete of corner, particle does not scatter and disappear then particularly critical.Currently used means be directly manually manually or
Core sample is proposed from drilling using the upper edge of flat-nose pliers gripping core sample, because flat-nose pliers and core sample lifting surface area are limited, and
And influenceed by drill bit thickness（Generally 5mm）, flat-nose pliers further can not be also deep into drilling, in addition the top of core sample
It is excessive and cause core sample corner crushed particles to scatter and disappear along core sample local stress for the more fragile position of whole core sample, is easily caused, very
Deformed to core sample（Such as asphalt pavement core sample）, finally the testing result of core sample thickness is had an impact, even resulting knot
Fruit does not meet testing requirements.Therefore design it is a kind of be deep into bore inner and the gripper clamp for protecting core sample can be wrapped, increase pincers
Effective contact area of mouth and core sample, avoids local stress excessive, effectively keeps the integrality of core sample to have highly important meaning
Justice.And clamping part on sale is mostly flat mouth or round mouth on the market at present, do not occur also dedicated for the clamping of effectively protection core sample
Instrument.
The content of the invention
The utility model provides one kind and is used for road surface coring core sample gripper clamp, and the purpose is to solve present on existing operation
Defect, clamping jaw is deep into bore inner and can be wrapped and protect core sample, effective contact area of increase jaw and core sample,
Avoid stress suffered by core sample part excessive, effectively keep the integrality of core sample, adapt to different size of core sample, be easy to manually grasp again
Make.
Technical scheme is used by the utility model solves its technical problem：
With two supporting rods, the front portion of supporting rod is clamping part, middle part is articulated section, rear portion is Handheld Division；Clamping part
Cross section be arc, clamping part includes concave surface, convex surface；Articulated section has several pin axis jacks, two supporting rods intersect and with
Bearing pin passes through corresponding pin axis jacks and is movably hinged, and the concave surface of two clamping parts is relative.
The angle of leading flank of the clamping part including connection concave surface front end and convex surface front end, leading flank and concave surface is sharp
Angle, lateral direction of the leading flank towards clamping part.
The concave surface of the clamping part is provided with sawtooth lines.
The thickness of the clamping part is 2mm.
The Handheld Division of the supporting rod and the connecting portion of articulated section are circular arc.
The Handheld Division end of the supporting rod has waveform rubber sleeve.
It is of the present utility model to be beneficial in that：
The utility model has the two root long handle supporting rods for intersecting and being movably hinged by bearing pin, the clamping of two supporting rods
It is cylindrical shape cylindric or jaggy when portion closes, wrapping clamping can be carried out to core sample, effectively avoid core sample local stress mistake
Greatly；Clamping part uses thickness, less than the thickness of drill bit, can be deep into bore inner for 2mm sheet metals；Clamping part leading flank designs
Binding clip propelling resistance in the borehole can be reduced for inclined-plane, bore inner can be deep into；Clamping part concave surface is provided with tiny hackle mark,
The stability and fixing of clamping in the frictional force in the case of not damaging core sample surface effectively between increase and core sample, can be strengthened；
Supporting rod articulated section is designed with several different pin axis jacks, and bearing pin is hinged supporting rod through different pin axis jacks, can used
In the folding size of regulation clamping part, different size core samples can be directed to and used；The Handheld Division end of supporting rod has waveform rubber
Gum cover, increasing friction force, it is easy to grasp.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model schematic diagram.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below
Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings
Example.
Formed as shown in figure 1, the utility model is hinged after being intersected by two supporting rods.
Supporting rod overall structure is divided into three parts, respectively clamping part 1, articulated section 2 and Handheld Division 3.
The cross section of clamping part 1 is arc, is made up of convex surface 11, side 14, concave surface 13, leading flank 12, side 14 connects
The homonymy side of convex surface 11 and concave surface 13, leading flank 12 connect the front end on convex surface 11 and the front end of concave surface 13.
The surface of concave surface 13 is provided with tiny sawtooth lines, can effectively increase on the premise of not damaging core sample surface between core sample
Frictional force.
Leading flank 12 and the angle of concave surface 13 are acute angle, and leading flank 12 is directed towards the inclined-plane of the lateral direction of clamping part 1,
I.e. the front end of clamping part 1 is pointed.The inclined design of this leading flank 12 can effectively reduce advance when gripper clamp stretches into drilling
Resistance.
Clamping part 1 is the sheet metal that thickness is 2mm, less than the thickness of drill bit, can be deep into bore inner.
There are 23 3 groups of pin axis jacks 21, pin axis jacks 22, pin axis jacks be hinged pin axis jacks in articulated section 2, two in Fig. 1
Supporting rod intersects and so that bearing pin passes through corresponding pin axis jacks 22 and is movably hinged, the concave surface 13 of two clamping parts 1 is relative.
When using different groups of hinge holes, such as and so that bearing pin passes through corresponding pin axis jacks 21 and is movably hinged, or
And so that bearing pin passes through corresponding pin axis jacks 23 and is movably hinged, different is be hinged available for two relative shapes of concave surface 13 of regulation
Into clamping jaw folding size, the jaw of gripper clamp can be applicable φ 75, φ 100 and φ 150 core sample sample respectively.
The Handheld Division 3 is made up of arc twist part 31, straight-bar portion 32 and the three parts of hand grip portion 33, the end of Handheld Division 3
Hand grip portion 33 is designed with waveform rubber sleeve, can effectively increase the frictional force between hand and handle, is easy to grasp operation.
Two clamping parts 1 of two supporting rods close namely when jaw closes, two clamping parts 1 can close to form cylinder
Shape, it is contemplated that jaw adapts to various sizes of core sample and used, and the structure that two closures of clamping part 1 are formed not is to close completely
Cylindrical structure, but the isocentric circular arc structure that each clamping part 1 designs convex surface 11, concave surface 13 is two each 120 ° of central angles, this
Two closures of clamping part 1 of sample are exactly to form a both sides to have the cylindrical structure of vertical cut (V. cut), so can be to core when extracting core sample
Sample wrapping clamping.
The utility model design structure is simple and convenient to operate, and can be deep into bore inner and protection, increase pincers are wrapped to core sample
Effective contact area of mouth and core sample, avoids local stress excessive, effectively keeps the integrality of core sample.
