Description
Technical field
The present invention relates to a kind of time compact form feeler lever trigger automatically, belong to a kind of piezocone penetration probe trigger in rock-soil engineering in-situ field tests.
Background technology
Static sounding technology (CPT) is as topmost in-situ testing technique, and the history of existing more than 80 year, widely uses in China soft clay area so far.Static sounding technology refers to and utilizes pressure apparatus by the sounding rod indentation test soil layer with contact probe, the static point resistance, side friction power etc. of throughput examining system test soil, some basic physical mechanics properties of soil can be determined, as the deformation modulus of soil, the allowable bearing etc. of soil.Hole pressure touching methods technology (CPTU) is the novel in-situ testing technique risen in the world the eighties in 20th century, compared with the quiet spy of single doube bridge that China is traditional, there is theoretical system, multiple functional, parameter is accurate, precision is high, the advantage such as good stability, both the sensitivity can pressed with super hole accurately divides soil layer, carries out great soil group differentiation, the in-situ consolidation coefficient, infiltration coefficient, kinetic parameter, structural parameters, bearer properties etc. of soil can be asked for again, be widely used in soft clay area at present.
When the injection of piezocone test feeler lever terminates, when extracting feeler lever, probe, be 1m because feeler lever often saves length, when extracting top one and saving feeler lever, bottom residue feeler lever due to Gravitative Loads can downward landing to static sounding hole in, frequent appearance is sliding bores or the situations such as brill that fall, destructive test instrument and equipment.At present, in piezocone test, when choosing feeler lever, do not have special feeler lever trigger to prevent the generation of above-mentioned situation, for preventing the sliding situation of boring or falling to boring, what usually adopt is that feeler lever clamped by various simple and crude instrument, and need many people to coordinate just to complete, poor reliability, efficiency is low, and potential safety hazard is large.
The present invention proposes a kind of easy, effective, can one man operation automatically return compact form feeler lever trigger, the feeler lever sliding generation of boring or falling to boring situation when can effectively prevent cone penetration test from terminating to get brill.
Summary of the invention
Technical matters: the technical problem to be solved in the present invention there is no for domestic at present the trigger preventing piezocone penetration probe from gliding specially, has invented a kind of time compact form feeler lever trigger automatically for hole pressure touching methods that can be used for preventing the sliding brill of piezocone penetration probe generation or fall to boring.
Technical scheme: of the present inventionly automatically return compact form feeler lever trigger for hole pressure touching methods, comprises base, a pair collar, turning block, mono-directional overrun clutch, slide block Ka Gou, bracing frame, fixing pin, axle rod, Compress Spring, returns tight spring, pedal, base immediately below a pair collar has a through hole, one end of described a pair collar is hinged on base by fixing pin, bracing frame is positioned at a pair collar side and is fixed on base, bracing frame is provided with mono-directional overrun clutch, the output shaft of mono-directional overrun clutch is axle rod, turning block is between the active open of a pair collar and be arranged on one end of axle rod, the two ends returning tight spring are separately fixed at the opening two ends of a pair collar, the active open of a pair collar is provided with slide block Ka Gou, one end of pedal is connected with mono-directional overrun clutch, Compress Spring is between pedal and base.
Antiskid thread is carved with in the inner side of a pair described collar.
The cross section of described turning block is strip, and its length is the width of a pair collar active open when opening, and its width is the width of a pair collar active open when closing.
The circular arc of described slide block Ka Gou and the circular arc of turning block outer rim match.
Beneficial effect: the invention solves piezocone test when getting brill, feeler lever drops down onto the problem in static sounding boring in Gravitative Loads downslide, and many people of former simple and crude poor efficiency coordinated on-slip to get brill mode to change efficient one man operation's on-slip into and get brill, for piezocone test provides safe and reliable feeler lever trigger.This trigger can the safety of available protecting piezocone test feeler lever equipment, improves the work efficiency of cone penetration test.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
The compact form feeler lever trigger that automatically returns for hole pressure touching methods of the present invention comprises base 1, a pair collar 2, turning block 3, mono-directional overrun clutch 4, slide block card ditch 5, bracing frame 6, fixing pin 7, axle rod 8, Compress Spring 9, returns tight spring 10, pedal 11, base 1 immediately below a pair collar 2 has a through hole 1-1, one end of described a pair collar 2 is hinged on base 1 by fixing pin 7, bracing frame 6 is positioned at a pair collar 2 side and is fixed on base 1, bracing frame 6 is provided with mono-directional overrun clutch 4, the output shaft of mono-directional overrun clutch 4 is axle rod 8, turning block 3 is between the active open of a pair collar 2 and be arranged on one end of axle rod 8, the two ends returning tight spring 10 are separately fixed at the opening two ends of a pair collar 2, the active open of a pair collar 2 is provided with slide block card ditch 5, one end of pedal 11 is connected with mono-directional overrun clutch 4, Compress Spring 9 is between pedal 11 and base 1.
Antiskid thread is carved with in the inner side of described a pair collar 2.A pair collar 2 internal diameter is 34mm, and external diameter is 50mm, height 60mm.
The external diameter 52mm of described mono-directional overrun clutch 4, internal diameter 20mm, width 15mm, keyway 4 × 1.8, apolegamy bearing 6304, inner ring is overhauled rotary speed 1100r/min, nominal torque 50N.m.
