(2) the utility model moves three drop center wheels above and below to move toward straightening reinforcing bar, will not destroy to pile crown reinforcing bar
Mechanical property while, also can guarantee the preferable straightening effect of pile crown reinforcing bar.
(3) two adjustment frames of the utility model use openable and closable form, can for the reinforcing bar of differently curved degree
It adapts to, can be quickly by pile crown steel bar clamping, applicability is wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the straightening head of the utility model.
Fig. 2 is the right side structural representation of Fig. 1.
Fig. 3 is the using state structure diagram of the utility model.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of device for straightening pile crown reinforcing bar is made of fixed frame and lifting lug, in which:
Straightening head is used for the pile crown reinforcing bar 15 of straightening pile crown concrete 12.The upper center two sides of upper frame 1 are equipped with lifting lug 2.Upper frame
Lower end on both sides of the middle be correspondingly provided with two fixed frames being distributed in interval distance 11 and two adjustment being distributed in interval distance
Frame 6.Two adjustment frame upper ends being distributed in interval distance are connect by axis bolt 4 and axis in the middle part of the lower end of upper frame.Two adjustment frames and
The lower end of fixed frame is connected by two adjusting screws 7, i.e. the lower end of two adjustment frames and fixed frame is set for two adjusting screws
The correspondence through-hole passed through, after the front end of two adjusting screws passes through corresponding through-hole, then it is fixed with two nuts 9, it will with fast and easy
The spacing of pile crown steel bar clamping and adjustment two adjustment frames and fixed frame, that is, adjust the first, second correction wheel and third correction wheel
Spacing.Upper and lower end on the inside of two fixed frames being distributed in interval distance is correspondingly provided with wheel carrier 21.Two wheel carrier front of upper end it
Between the first correction wheel 3 connect by 8 axis of wheel shaft, the second correction wheel 10 is connect by wheel shaft axis between two wheel carrier front of lower end.Two are in
The middle inside of the adjustment frame of spacing distance distribution is correspondingly provided with wheel carrier, connects third by wheel shaft axis between two wheel carrier fronts and corrects
Wheel 5.Third correction wheel is located between the first, second correction wheel.The wheel circumferential surface of first, second correction wheel and third correction wheel is recessed
