If 1 or 4, the diameter size of connecting cylinder 1, locking short circuit 5 is unanimous, and the diameter of the both ends diameter of centralizer 3 is unanimous with the diameter size of connecting cylinder 1, locking short circuit 5, and the diameter of the piece 7 of rightting of centralizer 3 is greater than the diameter of connecting cylinder 1, locking short circuit 5, ensures that the instrument is placed in the middle in the drilling tool through piece 7 of righting.
The diameter of the middle part of the centralizer 3 is matched with the diameter of a water hole in a drilling tool, and the on-site application is met.
As shown in fig. 3, the bottom end of the locking short joint 5 is arc-shaped, and the locking short joint 5 with the arc-shaped bottom end is beneficial to conveniently and quickly placing the exploring tube in the drilling tool, thereby playing a guiding role.
The difference from the embodiment 1 is that:
as figure 5, the upper end and the lower extreme diameter of locking short circuit 5 are unanimous with the diameter of connecting cylinder 1, and the middle part of locking short circuit 5 is supplementary piece 8 of rightting, and supplementary piece 8 diameter of rightting is unanimous with piece 7 middle part diameter size of rightting, and the bottom of locking short circuit 5 is circular-arc, through supplementary piece 8 of rightting to righting 7 supplementary righting effect of playing, through supplementary piece 8 of righting and righting 7 dual rightting of piece, right effectually.
As shown in fig. 7 or 8, the ball belt 11 is arranged on the peripheries of the centering block 7 and the auxiliary centering block 8, and the balls 12 are arranged on the ball belt, so that the friction between the centering block 7 or the auxiliary centering block 8 and the drilling tool is reduced, and the service life is prolonged.
During the use, along with boring probe and connecting cylinder 1 of inclinometer pass through threaded connection, connecting cylinder 1 passes through threaded connection with main shaft 4, centralizer 3 directly overlaps on main shaft 4, all there is sealing washer 2 on the up and down terminal surface of centralizer 3, locking short circuit 5 passes through threaded connection with main shaft 4, screw up, locking short circuit 5 passes through the screw-thread fastening back with main shaft 4, centralizer 3 is pressed from both sides tightly and unable activity, make sealing washer 2 play sealed effect, prevent that mud from getting into the clearance between centralizer 3 and the main shaft 4.
The utility model discloses replaced the terminal protection device of original probe, avoided its damage when changing the centralizer, practiced thrift the cost. Simultaneously, when changing the centralizer, reduced site operation personnel's intensity of labour, portable and field application, the utility model discloses light and handy convenience, easy operation, safe and reliable's terminal protection device of inclinometer along with boring in the pit. The device is directly arranged at the tail end of the probe pipe on a construction site, and can be independently finished by one person after being screwed by a friction wrench. The intensity of labour who has reduced the site operation personnel, the damage of original end device has been avoided, reach both simple and convenient, the purpose of practicing thrift the cost again, the middle part of locking short circuit is supplementary piece of rightting, it rights the effect to play supplementary righting to right the piece through supplementary piece of righting, right through supplementary piece of righting and the dual righting of piece of righting, it is effectual to right, it is equipped with the ball area to right the piece with supplementary periphery of piece of righting, be equipped with the ball on the ball area, reduce the friction of righting piece or supplementary piece of righting and drilling tool, and long service life.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the technical solutions described above. Therefore, any simple modifications or equivalent replacements made according to the technical solution of the present invention belong to the scope of the claimed invention as far as possible.
