[0012] As attached Figure 1 、 2As shown, the utility model provides a rod selection mechanism with a proximity switch, including a selection bracket 2, the selection bracket 2 is a Z-shaped bracket, one end of the selection bracket 2 is connected to the adjustment pad 1 by a fastening bolt 15, and one end of the selection bracket 2 is connected to the adjustment pad 1, and the other end of the selection bracket 2 is arranged in a groove opened inside the slide plate 3, and is connected to the slide plate 3 by a fastening bolt 2 16, and the top of the slide plate 3 is connected to the shift panel 5 by a D-ring 4, and the shift panel 5 is inserted into the groove opened in the slide plate 3, and is clamped between the selection bracket 2 and the inner wall of the groove of the slide plate 3, and five selection circular holes 51 are opened on the shift panel 5 at equal distances in the longitudinal direction, and the top of the shift panel 5 is fastened by a fastening screw Bolt three 17 is connected to the anti-collision plate 6, and the top of the shift panel 5 is connected to the proximity switch 7 through the fastening bolt four 18. The slide plate 3 is connected to the lower side of the rod taking arm support seat 8 through the fastening bolt two 16. A rod taking arm 10 is slidably provided in the slide groove opened above the rod taking arm support seat 8. One side of the rod taking arm 10 is connected to the serrated sensing plate 9 of the proximity switch through the fastening bolt five. The two sides of the rod taking arm support seat 8 are respectively connected to the rod mounting motor 11 through the fastening bolt six. The rod mounting motor 11 is connected to the gear shaft 12 through a spline, and the two adjacent gear shafts 12 are connected by a synchronization rod 13. A drill rod box 14 is provided above the rod taking arm support seat 8, and five rows of drill rods are placed in the drill rod box 14.
[0013] Specifically, the fastening bolt 15 passes through the bolt hole 1 opened at one end of the row selection bracket 2 and the strip hole 101 opened on the surface of the adjustment pad 1, thereby fastening the row selection bracket 2 to the adjustment pad 1.
[0014] Specifically, four bolt holes 2 are arranged in a four-square grid on both sides of the slide plate 3, and four bolt holes 3 are also arranged in a four-square grid on the other end of the selection bracket 2. The fastening bolts 2 16 pass through the bolt holes 2 and the bolt holes 3 respectively to fasten the selection bracket 2 to the slide plate 3.
[0015] Specifically, the proximity switch sawtooth sensing plate 9 is provided with five rows of teeth in a stepped shape.
[0016] Specifically, a rack is provided at the lower end of the lever-taking arm 10 .
[0017] Working principle: When starting work, take the first row of rods in the drill rod box 14, that is, the innermost rods, first remove the D-ring 4, move the shift panel 5 downward, and when the first round hole in the shift panel 5 from the top to the bottom coincides with the D-ring mounting hole of the row selection bracket 2 and the slide plate 3, then install the D-ring 4. At this time, the horizontal position of the proximity switch 7 is consistent with the height of the lowest row of teeth on the proximity switch serrated sensing plate 9;
[0018] During operation, when the rod taking arm 10 moves backward to take out the rods, the proximity switch serrated sensing plate 9 on it moves with it. When its lowermost row of teeth contacts and senses the proximity switch 7, the proximity switch sends a signal to cut off the power of the rod loading motors 11 on both sides to stop them. The gear shaft 12 connected to the rod loading motor 11 and the rod taking arm 10 with the rack also stop moving and are fixed in this position. At this time, the rod taking groove at the front end of the rod taking arm 10 corresponds to the position of the first row of rods in the drill rod box, thereby realizing the rod taking work of the first row of rods in the drill rod box 14.
[0019] After the first row of rods in the drill rod box 14 is taken out, the second row of rods is taken out. At this time, the D-ring 4 is removed and the shift panel 5 is moved downward again. When the second round hole from the top to the bottom of the shift panel 5 coincides with the D-ring mounting hole of the row selection bracket 2 and the slide plate 3, the D-ring 4 is installed. At this time, the horizontal position of the proximity switch 7 is consistent with the height of the second to last row of teeth from the top to the bottom of the proximity switch serrated sensing plate 9;
[0020] During operation, when the rod taking arm 10 moves backward to take the rod, the proximity switch serrated sensing plate 9 on it moves with it. When the second to last row of teeth from the top to the bottom contacts and senses the proximity switch 7, the proximity switch sends a signal to cut off the power of the rod loading motors 11 on both sides to stop it. The gear shaft 12 connected to the rod loading motor 11 and the rod taking arm 10 with the rack stop moving and are fixed in this position. At this time, the front end rod taking groove of the rod taking arm 10 corresponds exactly to the position of the second row of rods in the drill rod box 14, thereby realizing the rod taking work of the second row of rods in the drill rod box.
[0021] Similarly, repeat the above steps to sequentially take out the 5 rows of drill rods in the drill rod box 14.
