Abstract
The utility model relates to a dragline type testing operating system for a sliding deforming meter, which can complete continuously the circular processes of drill hole feeding-state transformation of a measuring head-stress application testing of the sliding deforming meter or a sliding micrometer. The whole system of the utility model is composed of an aperture winch, an upward pulling cable, a downward pulling cable, two springs which matches in specified rigidity in the sliding deforming meter, a rotary control device and a guiding chain. In the process of operation, five kilogram-force of artificial application force, which can be magnified by the aperture winch to generate thirty kilogram-force, is required, the process of operation is simply repeated, and testing force is always constant.
Description
The utility model relates to the drag-line Test Operating System of a kind of sliding deformeter and slip micrometer.
At present popular in the world sliding deformeter or slip micrometer (in order to test rock mass internal modification rule) test macro mainly is made of slotted line, deformation gauge, drag chain, pull bar and surface installation.Measure linear system and be embedded in the interior retable material conduit of boring.Conduit is bonded in borehole wall along hole length by grout.Long one meter of conduit, end to end, measurement markers of joint installing.The measurement ring that a band longitudinal groove is arranged in the measurement markers.The spheric probe at deformation gauge two ends also has longitudinal groove, makes it to form pintongs.Drag chain is connected the deformation gauge bottom.Two meters of the single length of pull bar use total radical to decide on the slotted line length overall.During test pull bar is connected to the deformation gauge top, deformation gauge gauge head cross lobe is aimed at the measurement ring groove, by picking pull bar deformation gauge is free to slide vertically in the slotted line total length under this sliding mode.When deformation gauge slides to certain to be measured section, 45 ° of rotating tension bars, the cross lobe of gauge head will be aimed at the boss of measurement ring groove both sides and be in the measurement state this moment, if spur pull bar again, then deformation gauge is owing to the obstruction of measurement ring boss will no longer be slided.Continuation applies axial force by pull bar, and deformation gauge will be drawn back, and the conical surface of surveying ring in the measurement face of bulb up and down and adjacent two measurement markers is adjacent to.This moment, deformation gauge can be measured the distance between two adjacent measurement markers.The test operation of the sliding deformeter of current popular mainly by boring send deformation gauge to, the rotational deformation meter changes its state, apply test force by pull bar again and finish.Therefore whole test is finished by rice along hole depth, needs frequent mounting or dismounting pull bar, and each measuring point all needs the operator manually to apply pulling force about 30 kilograms.By surveying long 50 meters, operating personnel's physical demands is well imagined; In addition,, be difficult to guarantee that weighing apparatus is fixed, certainly will produce test error because test force system manually applies.
The purpose of this utility model provides a kind of sliding deformeter drag-line Test Operating System.It by the aperture winch, on draw spring assembly, rotating control assembly and drag chain in cable wire, drop-down cable wire, the deformation gauge to constitute.Native system only depends on two cable wires, by ground winch control, can realize conveniently that sliding deformeter boring sends the operating process of gauge head state transformation, afterburning test to.
The purpose of this utility model is achieved in that the winch of adorning a band dynamometer on boring ground, the cable wire that wheel disc is drawn on the winch is connected in the deformation gauge upper end, the cable wire that wheel disc is drawn under the winch extends at the bottom of the hole, runner is connected with drag chain at the bottom of walking around the hole, and the swivel control head of drag chain and deformation gauge bottom joins.Being constructed as follows of deformation gauge itself: with the urceolus of going up measuring head and displacement transducer, the inner core of measuring head links to each other urceolus with being with down by big rigid spring, and inner core then joins by little rigid spring and swivel control head.The fixed pin of little rigid spring inserts the spiral guide slot of inner core.Test operating procedure is as follows: drag chain can keep swivel control head not produce rotation around the hole axle all the time in the hole; Fixing lower end drag-line, on pull on the end drag-line, inner core will do under the control of Spin Control pin and the spiral guide slot of itself along the hole axially on and around the compound motion of hole axle rotation till rotating 26 °～30 °; Continue to give upper end drag-line reinforcing, inner/outer tube is drawn back, and measuring head up and down and measurement markers in the hole are adjacent to, and applying power is decided by control of the dynamometer in the winch and weighing apparatus, sheds steel cable stretching force, total system reinstatement attitude again behind the survey read bit displacement sensor reading.Finish a test loop this moment, prepare to enter next circulation.
Owing to adopt such scheme,, only just can finish the operating process that---gauge head state transformation---afterburning test is sent in sliding deformeter boring to by drawing two cable wires by the control of aperture winch.This Operational System Control is easy, and pull bar need frequently not adorned, be torn open to whole test process, can alleviate operating personnel's working strength greatly, and can guarantee that test force is fixing all the time, thereby has eliminated the measuring error that produces therefrom.
Below in conjunction with drawings and Examples this sliding deformeter drag-line Test Operating System is described further.
Fig. 1 is the vertical section structure figure of first embodiment of the utility model.
Fig. 2 is the cross-sectional configuration figure that goes up measuring head when sliding deformeter is in sliding mode in the utility model operating process.
Fig. 3 is the cross-sectional configuration figure that the utility model operating process towel sliding deformeter is gone up measuring head when being in the measurement state.
Fig. 4 is the vertical section structure figure (that is Fig. 1 L is to cut-open view) of second embodiment of the utility model.
Among the figure, 1. draw on cable wire 4. drop-down cable wire 5. deformation gauges under measuring head 6. displacement transducers 7. deformation gauge urceolus 8. deformation gauge inner cores 9. big rigid spring 10. little rigid spring 11. swivel control heads 12. deformation gauges cable wire reverse wheel at the bottom of measuring head 13.
