Specific embodiment
Referring to FIG. 1 to FIG. 6, the tapping machine center hook automatic coupling/decoupling device of the utility model, comprising: moving trolley 10,
The moving trolley 10 includes bottom plate 101 and its guide wheel 102 that two sides are vertically arranged by support plate；Its further include:
Center hook seat 1, the upper end are connected to the lower side of bottom plate 101 of the moving trolley 10；
Rotation center hook 2, middle part side are pivotably coupled to 1 lower part of center hook seat, the rotation by pin shaft
The other side for turning 2 middle part of center hook extends outward to form hook portion 21；2 top of rotation center hook is close to the side of hook portion 21
Inclined-plane, top end face center set groove 22, form U shape guide groove；2 bottom of rotation center hook extends to form backstop to two sides
Portion 23；Rotation center hook 2 is the hook of a centre-of gravity shift；
Drilling rod baffle 3, the other side being vertically arranged under the bottom plate 101 of the moving trolley 10, limits drilling rod with this
30；
Attachment base 4, the other side being set under the bottom plate 101 of the moving trolley 10；
Movable support rod 5, one end are pivotally connected to the attachment base 4, which is located at the center hook seat
Before 1, and it is arranged in the groove 21 in 2 top end face of rotation center hook center；The middle part bottom surface of the movable support rod 5 is limited position
Step 51,
Drive rod 6, comprising:
Outer tube 61, the upper end sets U-shaped interconnecting piece 62, and is movably connected on the another of the movable support rod 5 by bolt
One end；
Fixing seat 63 is set to 61 internal upper part of outer tube, and center sets through-hole；
Connecting rod 64, upper part is arranged in 63 through-hole of fixing seat, and is locked by a fixture nut 65；
Mandril 66 is buffered, 64 lower end of connecting rod in the outer tube 61 is connected to, buffers and stretches in institute outside 66 lower part of mandril
It states outside outer tube 61；
Spring 67 is sheathed in the connecting rod 64, and it is gentle that 67 upper and lower side of spring bears against 63 bottom surface of fixing seat
It rushes to summit 66 top surface of bar.
Referring to Fig. 7~Fig. 9, be open the automatically-unhooked course of work of driver drilling rod, changes pricker machine and runs to below tapping machine, changes pricker machine
Drilling rod claw 20 is begun to ramp up, and buffering mandril 64 is encountered in uphill process, drives buffering mandril 64 to rise together, drive rod 6
Rise；6 top of drive rod is hingedly connected together with movable support rod 5, also drives movable support rod 5 when drive rod 6 rises
Using pin shaft as the rotary motion in the center of circle, as shown in fig. 7, support of the release to rotation center hook 2；Rotation center hook 2 is made in gravity
An angle is rotated clockwise automatically with lower beginning, as shown in Figure 8；It changes under pricker driver drilling rod claw 20 holds and start after drilling rod 30
Drop, because the control that rotation center hook 2 has got rid of movable support rod 5 is freely rotatable, so drilling rod 30 can be smoothly detached from rotation
Heart hook 2, as shown in figure 9, achieving the purpose that automatically-unhooked.
Referring to Figure 10~Figure 12, be open the driver drilling rod automatic coupling course of work, change 20 support of pricker driver drilling rod claw new brill
Bar 30 is run to below tapping machine, is changed pricker driver drilling rod claw 20 and is held drilling rod 30 and begins to ramp up, and the drilling rod 30 in rising encounters rotation
Behind the lower part for turning center hook 2, as the continuous rising rotation center hook 2 of drilling rod 30 starts to rotate counterclockwise, rotation center hook 2
Top slip over movable support rod 5 after open drive rod 6 (as shown in Figure 10), so that drive rod 6 is rotated clockwise an angle,
As shown in figure 11, it avoids and changes colliding for pricker driver drilling rod claw 20 with rising, after drilling rod 30 passes through rotation center hook 2,
The support that rotation center hook 2 loses drilling rod 30 starts to rotate clockwise, when the top of rotation center hook 2 slides into movable support rod
When 5 support zone, the limited step 51 of movable support rod 5 has withstood upper end-support portion of rotation center hook 2, in rotation
Heart hook 2 can not be rotated clockwise again by control, as shown in figure 12；The drilling rod 30 starts after having passed through rotation center hook 2
Decline, drilling rod 30 encounters rotation center hook 2 when declining, because rotation center hook 2 can not rotate, so rotation center hook 2 is just firmly
Hold drilling rod 30；Changing after pricker driver drilling rod claw 20 releases drilling rod 30 can continue to decline a distance, be then departed from tapping machine,
Complete the replacement of drilling rod.
