Description
Technical field
The present invention relates to a kind of auto back compact form feeler lever trigger, 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, is widely used in China soft clay area so far.Static sounding technology refers to utilizes pressure apparatus by the sounding rod indentation test soil layer with contact probe, throughput examining system is tested native static point resistance, side friction power etc., can determine some basic physical mechanics properties of soil, as the allowable bearing etc. of native modulus of deformation, soil.It is the novel in-situ testing technique rising in the world the eighties in 20th century that static sounding technology (CPTU) is pressed in hole, compared with the quiet spy of single doube bridge traditional with China, there is theoretical system, the advantage such as multiple functional, parameter is accurate, precision is high, good stability, both can accurately divide soil layer, carry out great soil group differentiation by the sensitivity that press in super hole, can ask for again native in-situ consolidation coefficient, transmission coefficient, kinetic parameter, structural parameters, bearer properties etc., be widely used in soft clay area at present.
When the injection of piezocone test feeler lever finishes, while extracting feeler lever, probe, because the every joint length of feeler lever is 1m, in the time that feeler lever is saved on extraction top one, residue feeler lever in bottom is due in Gravitative Loads can downward landing to static sounding holes, often there is sliding boring or the situations such as brill that fall, destructive test plant and instrument.At present, in piezocone test, in the time 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 conventionally adopt is that various simple and crude instruments are clamped feeler lever, and need many people to coordinate just and can complete, poor reliability, efficiency is low, and potential safety hazard is large.
The present invention proposes a kind of easy, effective, auto back compact form feeler lever trigger that can one man operation, can effectively prevent that cone penetration test from finishing to get the sliding generation of boring or falling to boring situation of feeler lever while boring.
Summary of the invention
Technical problem: the technical problem to be solved in the present invention is for the at present domestic trigger that prevents specially piezocone penetration probe downslide that there is no, has invented a kind of sliding auto back compact form feeler lever trigger for hole pressure static sounding that bores or fall to boring of piezocone penetration probe generation that can be used for preventing.
Technical scheme: auto back compact form feeler lever trigger of pressing static sounding for hole of the present invention, comprises base, a pair of collar, turning block, mono-directional overrun clutch, slide block Ka Gou, bracing frame, fixing pin, axle rod, Compress Spring, returns tight spring, pedal, on base under a pair of collar, have a through hole, one end of the described a pair of collar is hinged on base by fixing pin, bracing frame is positioned at a pair of 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 of collar and be arranged on one end of axle rod, the two ends of returning tight spring are separately fixed at the opening two ends of a pair of collar, on the active open of a pair of collar, be 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 the described a pair of collar.
The cross section of described turning block is strip, and its length is the width of a pair of collar active open while opening, and its width is the width of a pair of collar active open when closed.
The circular arc of the circular arc of described slide block Ka Gou and turning block outer rim matches.
Beneficial effect: the invention solves piezocone test and get while boring, feeler lever glides and drops down onto the problem in static sounding boring at Gravitative Loads, and coordinate on-slip to get brill mode many people of former simple and crude poor efficiency 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 effectively be protected the safety of piezocone test feeler lever equipment, improves the operating efficiency of cone penetration test.
