It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore describe the use of positional relationship in attached drawing
Language only for illustration, should not be understood as the limitation to this patent, for the ordinary skill in the art, can be with
The concrete meaning of above-mentioned term is understood as the case may be.
It is preferred embodiment provided by the invention referring to Fig.1 shown in -3.
Inclinometer reverse ratchet device, loop bar 30 and rescue structure 60 including strip, the outside of loop bar 30 is provided with multiple
Directive wheel 20, and multiple directive wheels 20 are arranged in outside the two sides of loop bar 30；Rescue structure 60 is connected on loop bar 30, is saved
Structure 60 includes flat stake needle 40 that is in a strip shape and being arranged in 30 outside of loop bar, and flat stake needle 40 has extends to 30 lower section of loop bar downward
Extended segment, along top-down direction, centerline dip of the extended segment towards loop bar 30, and the end of extended segment and loop bar 30
Center line between have gap.
The inclinometer reverse ratchet device of above-mentioned offer, by the way that multiple directive wheels 20 are arranged in the outside of loop bar 30, and will solution
It rescues structure 60 to be connected on loop bar 30, rope 10 is tied up to the upper end of loop bar 30, rescue structure 60 includes in a strip shape and is arranged in
The flat stake needle 40 in 30 outside of loop bar, in this way, when inclinometer is stuck in inclinometer pipe, by above-mentioned inclinometer reverse ratchet device by leading
It is transferred in guide groove to wheel 20, under the effect of gravity, flat stake needle 40 compresses on the directive wheel 20 on inclinometer, by inclinometer
Pushed back by card directive wheel 20, rope 10 is lifted, then lift inclinometer conducting wire can safe solution rescue by card inclinometer, have
Cost of manufacture is cheap, and the processing is simple and advantage easy to operate, and is not necessarily to excavation and other destructions, remarkable in economical benefits,
With very strong practicability.
In addition, there is guide groove in inclinometer pipe, and what flat stake needle 40 was planar as, and the width of flat stake needle 40 is less than deviational survey
The width of the guide groove of pipe, in this way, carrying out in the decentralization to guide groove of inclinometer reverse ratchet device constantly capable of easily entering, no
It can be scratched with the cell wall of guide groove, to keep operation more smooth.
The installation sheet of inclined arrangement is equipped in loop bar 30, the both ends of installation sheet extend respectively into the two sides of loop bar 30
Outside；Installation sheet includes upper installation sheet 21 and the lower installation sheet 22 positioned at upper 21 lower section of installation sheet, the both ends point of upper installation sheet 21
Directive wheel 20 is not installed, one end of lower installation sheet 22 is equipped with directive wheel 20, when being transferred to inclinometer reverse ratchet device,
Directive wheel 20 is against on the cell wall of guide groove, can be played the role of being oriented to inclinometer reverse ratchet device, be can guarantee inclinometer solution
It rescues device to transfer along the extending direction of inclinometer pipe, and remains parallel between inclinometer pipe.
In addition, upper installation sheet 21 and lower installation sheet 22 are in tilted layout in the same direction, in this way, inclinometer rescue is further kept to fill
Set the parastate in decentralization process with inclinometer pipe.
In decentralization process, when the thickness for encountering guide groove changes, have very much in guide groove in inclinometer reverse ratchet device
It may be stuck in guide groove, the problem of appearance can not be transferred or can not taken, therefore, we will be placed in the middle part of installation sheet
In loop bar 30, and it is rotatablely connected with loop bar 30, in this way, when inclinometer reverse ratchet device transfers to the relatively narrow place of guide groove, installation sheet
It is rotated, the width of inclinometer reverse ratchet device becomes smaller, and then passes through guide groove, has bigger fault-tolerance.
The side wall of loop bar 30 is equipped with along the linear hole that loop bar 30 is axially arranged, installation sheet passes through linear hole；Connect on installation sheet
It is connected to driving installation sheet and resets oblique reset spring, when inclinometer reverse ratchet device is by the different guide groove of width,
Reset spring drives installation sheet to reset, and inclinometer reverse ratchet device is returned to original state, can further be transferred.
Furthermore the middle part of flat stake needle 40 is protruding with mounting blocks 51 towards loop bar 30, and mounting blocks 51 are located at the lower section of loop bar 30,
Mounting blocks 51 are equipped with connection adjustment structure 50, and connection adjustment structure 50 is connect with the lower part of loop bar 30, and adjusts flat stake needle 40
It moves up and down relative to loop bar 30, because the extended segment of flat stake needle 40 is directed towards the centerline dip arrangement of loop bar 30, passes through
Adjust moving up and down for flat stake needle 40, thus it is possible to vary the tilt angle of flat stake needle 40 is pressed on flat stake needle 40 more accurately
On the directive wheel 20 for the inclinometer being stuck, and then improve the efficiency and success rate of rescue.
Connecting adjustment structure 50 includes threaded rod 52, and threaded rod 52 passes through mounting blocks 51, and the bottom thread with loop bar 30
Connection, is threadedly coupled simple and convenient quick detachable, and operation can be completed in one, also easy to disassemble and deposit in addition, after rescue
It puts.
Flat stake needle 40 has hinge segment 41, and hinge segment 41 faces the outside arrangement of loop bar 30, and mounting blocks 51 are formed in hinge
The lower section of section 41 is connect, hinge segment 41 and the other end of lower installation sheet 22 are hinged, in this way, the hinged directive wheel in one end of lower installation sheet 22
20, the hinged hinge segment 41 of the other end simplifies connection adjustment structure 50, in addition, lower installation sheet 22 can be rotated and can pass through reset
Spring automatic reset, therefore flat stake needle 40 will not interfere in the process lower section.
Furthermore in the bottom of extended segment, setting is multiple supports piece, supports piece and supports arranged for interval between piece, adjacent supports between piece
With interval region, to being independent between piece, in this way, there are multiple extensions to piece when transferring inclinometer reverse ratchet device
Section has bigger abutting range, can more rapid and better complete the rescue to inclinometer.
Flat stake needle 40 has away from the back side of loop bar 30, and the back side is convexly equipped with multiple round salient points, and round salient point can increase
The intensity of flat stake needle 40 preferably compresses in this way, flat stake needle 40 is not easy deformation when compressing to directive wheel 20 to reach
Effect.
In addition, be equipped with headlamp and video camera in the bottom of the extended segment of flat stake needle 40, and by headlamp and video camera
The inside of rope 10 is arranged in power supply line, in this way, can control headlamp and video camera after the completion of decentralization, it will be in inclinometer pipe
The information in portion passes to constructor, can more comprehensively recognize by the state of card inclinometer, and then more targeted to quilt
Card inclinometer is saved.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
