The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done further to describe in detail:
A kind of digging hole filling pile hole quality checkout gear, as depicted in figs. 1 and 2, comprises main scale 1, secondary chi 2, light-beam transmitter 3 and for supporting the supporting leg of main scale and secondary chi, wherein supporting leg comprises two main supporting legs 41 and a secondary supporting leg 42.The two ends of main scale 1 are arranged on respectively on main supporting leg 41; One end of secondary chi 2 is hinged on the middle part of main scale 1, and the other end is arranged on secondary supporting leg 42; Light-beam transmitter 3 is suspended on secondary chi 2 by catenary.
Main supporting leg 41 comprises a supporting seat and a double-screw bolt perpendicular to supporting seat upper surface, and on double-screw bolt, two nuts are arranged at interval, and the end of main scale is between two nuts.The structure of secondary supporting leg 42 is identical with main leg structure.
Secondary chi 2 is also that a cross section is the strip ruler of rectangle, one end of secondary chi 2 is the middle part at main scale 1 by bearing pin and equipped bearing hinge connection, the other end is installed on the double-screw bolt of secondary supporting leg 42, on the double-screw bolt of secondary supporting leg 42, also two nuts are arranged at interval, one is positioned at the below of secondary chi 2, be used for holding up secondary chi 2 and secondary chi 2 is adjusted to level, another is positioned at the top of secondary chi 2.On secondary chi 2, portrayed graduation mark, the starting point (being zero graduation line) of graduation mark is positioned at the pin joint place of main scale and secondary chi, the distance between the current graduation mark of readings signify and the center, hinged place of graduation mark.The side of graduation mark is offered suspension groove 21, and suspension groove 21 is along the length direction setting of secondary chi 2, and runs through the upper and lower surface of secondary chi 2.The middle part of secondary chi 2 is also provided with secondary chi level gauge 22, and secondary chi level gauge 22 is also bubble and scale.
Light-beam transmitter 3 in the present embodiment is the infrared rays pen that a head can be launched red beam, and the afterbody of infrared rays pen is suspended to by a catenary bolt in the suspension groove 21 of secondary chi 2, and catenary is a plastic ties.
While using the present invention to carry out quality examination to stake hole, first two main supporting legs 41 are fixed on to an outside, hole, and main scale 1 is overlapped with the base center in stake hole with the pin joint of secondary chi 2; Secondly by regulating the height of nut on main supporting leg 41 double-screw bolts to make main scale 1 two ends maintenance level, be in course of adjustment and can determine whether level of main scales by observing main scale level gauge 12; Adjust again the position of catenary in suspension groove 21, make the graduation mark reading that catenary hanging position is corresponding corresponding with the design radial in stake hole; Then open the switch of infrared rays pen, infrared rays nib portion is naturally drooped straight down; Finally, secondary chi is rotated to the position that needs detection, and the height that regulates secondary supporting leg 42 double-screw bolt top nuts makes secondary chi 2 maintenance levels, after treating that infrared rays pen stops rocking, can judge that by observing the position of red beam spot whether stake bore dia and the verticality at this place be qualified.Can change continuously survey mark by revolute pair chi 2, thereby realize the comprehensive fast detecting to stake hole sidewall.Because red beam penetration power is subject to by force and not interference in air flow, therefore there is higher accuracy and detection efficiency than traditional plumb bob suspension method.
