Description
Technical field
The invention belongs to the earthwork test Instrument equipment technical field, be specifically related to a kind of soil sample ramming device three lobe cylinder locked instruments, relate in particular to a kind of pedal telescopic earth sample compacting device three lobe cylinder locked instruments.
Background technology
In civil engineering work practice and theoretical research process, for the mechanical characteristics such as intensity, distortion and pore water pressure of measuring soil sample, generally adopt strain to control formula unconfined compression apparatus and the strain control formula triaxial apparatus shop experiment of being correlated with.All need to prepare soil sample but adopt which kind of instrument to be tested, the quality of preparation of soil sample quality directly affects the success or not of test.Shop experiment diameter commonly used is 39.1mm, highly is the soil sample of 80mm.The needed ramming device three lobe cylinder normal inner diameter of preparation soil sample and height and soil sample consistent size, maximum outside diameter and cuff internal diameter are 50mm, and the cuff external diameter is 60mm, and its thickness is 6mm, and cuff upper end when being locked three lobe cylinders is 55mm with cylinder end mean distance.
When laboratory prepares soil sample, generally need two people's cooperations just can complete.Wherein people's both hands are pinned all the time cuff three lobe cylinders are fixed on the ground, and another people is filled soil and hits positive activity, generally need the dress soil of 3 circulations to hit positive activity and could prepare what a soil sample.In layering, hit in real process, due to the stressed vibrations of cuff are lax and both hands to fix the dynamics of three lobe cylinders different, three lobe cylinders tend to occur tilting or the phenomenon of horizontal displacement, cause soil sample to be exposed from bottom or to hit reality inhomogeneous, affect preparation of soil sample quality; Simultaneously, if two people can not effectively cooperate, also there will be drops hammer wounds by the safety problem of holding up finger, this method of operating not only wastes time and energy but also have potential safety hazard, therefore, a kind of new soil sample ramming device three lobe cylinder locked instruments of needs invention, complete preparation of soil sample work so that efficient, safe, high-quality.
Summary of the invention
The purpose of this invention is to provide a kind of pedal telescopic earth sample compacting device three lobe cylinder locked instruments, this device soil sample ramming device three lobe cylinders that not only can effectively be locked, guarantee the preparation quality of soil sample, and simple in structure, safe and efficient, time saving and energy saving.
The technical solution used in the present invention is: pedal telescopic earth sample compacting device three lobe cylinder locked instruments mainly are comprised of pedal, boss and ring cowling sleeve; Described pedal is two rectangular steel plates, each long 120mm, wide 110mm, thick 3mm; Described boss is the rectangular parallelepiped of a square sectional, high 20mm, and the square length of side is 110mm, middle perforate external threading, Major Diam is 80mm, and path is 76mm, and pitch is 2mm; The high 55mm of described ring cowling sleeve, thick 5mm, the external diameter of upper end ring cowling is 76mm, internal diameter is 50mm, the large footpath of lower thread is 80mm, and path is 76mm, and pitch is 2mm, two right cylinder torsion bars of the symmetrical installation in the ring cowling sleeve outside, the diameter of torsion bar is 8mm, length is 15mm.
Using method of the present invention is: the rectangle base that at first will be comprised of pedal and boss lies against on ground, operator's both feet slam pedal, the fixed length plinth, then, be placed in three lobe cylinders the hollow position, middle part of boss, the ring cowling of ring cowling sleeve was overlapped to three lobe cylinder tops, and bush whorl is aimed at the boss screw thread, and then with hand, pull torsion bar, the ring cowling sleeve turns clockwise, it slowly is screwed into to boss, until ring cowling locking cuff.Now, whole three lobe cylinders firmly are locked, and the operator, after each dress soil hits real the end, rotates the tight cuff of ring cowling sleeve lock again, and repeatable operation like this, until the preparation of soil sample completes.The soil sample sample preparation is rotated counterclockwise torsion bar after finishing, and ring cowling sleeve and rectangle base are separated, and takes out three lobe cylinders.
Principle of work of the present invention is: the ring cowling end of pedal telescopic earth sample compacting device three lobe cylinder locked instruments has a circular hole, the diameter of this circular hole is consistent with the internal diameter of soil sample ramming device three lobe jacket casing hoops, after with the ring cowling sleeve, soil sample ramming device three lobe barrel covers being lived, the ring cowling circular hole periphery steel plate of ring cowling sleeve is pressed on the coboundary of soil sample ramming device three lobe jacket casing hoops, now, by rotation ring cowling sleeve, the height of regulating sleeve, thereby ramming device three lobe jacket casing bandings are tightly suppressed, simultaneously, operating personnel can slam with both feet the rectangle pedal of pedal telescopic earth sample compacting device three lobe cylinder locked instruments, thereby soil sample ramming device three lobe cylinders are firmly fixing.
The invention has the beneficial effects as follows: pedal telescopic earth sample compacting device three lobe cylinder locked instruments can firmly be fixed soil sample ramming device three lobe cylinders easily, prevent that soil particle from overflowing from the ramming device bottom in native sample compacting process, reduce sample preparation error, simultaneously, this device can complete by people's independent operation, compare traditional method of operating, can greatly save manpower and workload, in addition, pedal telescopic earth sample compacting device three lobe cylinder locked instruments are simple in structure, with low cost, easy to operate, safe and efficient, practical.
