Embodiment
Embodiment, being shown in shown in Fig. 1 to Fig. 3: bolt drawing detector, being fixed on the anti-pulling ability of the test bolt 200 in body of wall 100 for detecting lower end.Concretely, this bolt drawing detector comprises: firm banking 10, hollow oil pump 20, hydraulic pressure display gauge head 30, coupling bolt 40, parts such as conversion nut 50, gland nut 60 etc.Wherein:
This firm banking 10 comprises horizontal part 11 and is positioned at 2 leg section 12 of this horizontal part 11 liang of side lower parts, and the middle part of this horizontal part 11 is provided with vertical through holes 13.
This hollow oil pump 20 is positioned over the top of the horizontal part 11 of this firm banking 10.This hollow oil pump 20 comprises outer sleeve 21, inner sleeve 22, piston cylinder 24, sealing bore 25.The lower end of this outer sleeve 21 and the lower end of this inner sleeve 22 are tightly connected and are formed with the space 23 of upper end open therebetween, are filled with hydraulic oil in this space 23.Meanwhile, the upper end of this piston cylinder 24 be tightly connected sealing cylinder 25 upper end and be formed with the gap 26 of lower openings therebetween.The side wall inner surfaces of sealing cylinder 25 and the wall outer surface of this outer sleeve 21 are sealed and matched.Such as, the side wall inner surfaces of sealing cylinder 25 or the wall outer surface of this outer sleeve 21 are provided with O-ring seal.The wall outer surface of this piston cylinder 24 and the side wall inner surfaces of this inner sleeve 22 are sealed and matched.Such as, the wall outer surface of this piston cylinder 24 or the side wall inner surfaces of this inner sleeve 22 are provided with O-ring seal.Now, this space 23 is mutually through with this gap 26, is also full of hydraulic oil in this gap 26.
This hydraulic pressure display gauge head 30 is communicated with this space 23 by a connecting pipe 31.That is, the hydraulic oil in this hydraulic pressure display gauge head 30 forms path with the hydraulic oil in this space 23.
These coupling bolt 40 two ends all have external thread.
This conversion nut 50 lower end and this test bolt 200 are spirally connected, the lower end of upper end and this coupling bolt 40 is spirally connected.
And the upper end of this coupling bolt 40 is from bottom to up successively through after this vertical through holes 13, this piston cylinder 24, and this gland nut 60 is spun on the top of this coupling bolt 40.
