The double-layer adjustable finger beam is composed of upper layer finger beam and lower layer finger beam, both of which are fixed on the inner beam 2 of the platform body 1; the control system 3 connects the electric cylinder 12, electric cylinder A 24 and oil cylinder 28 in the double-layer adjustable finger beam, and realizes the turnover of the finger beam door latch, the adjustment of the distance between the finger beams and the locking of the position by controlling the extension and contraction of the electric cylinder and the oil cylinder.​​​​

[0028] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the upper finger beam in the double-layer adjustable finger beam in the present application is composed of an upper finger beam 5, a finger beam latch 7, a positioning device 8, an ear plate 9, a limiting ring 10, an extension beam 11, an oil cylinder 28, and an upper guide plate 30. The upper finger beams 5 are evenly welded on the extension beam 11 at equal intervals, and the interval between adjacent upper finger beams 5 meets the discharge requirement of the maximum drill string size as required by the design. A through hole and a bolt hole are provided on the upper finger beams 5. After the finger beam latch 7 passes through the through hole on the upper finger beam 5, it is fixed by a bolt to prevent the drill string from coming out. The ear plate 9 has three ear plates, which are evenly distributed and fixed on the inner beam 2. The extension beam 11 passes through the through hole on the ear plate 9 and can move in and out in the ear plate 9. The limiting ring 10 is located on the inner side of the ear plate 9 and is fixed on both sides of the extension beam 11 to prevent the extension beam from coming out. The oil cylinder 28 is connected to the extension beam 11 at one end and to the table body 1 at the other end, and is used to control the extension and retraction of the extension beam 11 in the ear plate 9. The positioning device 8 is fixed on the ear plate 9 and is used to position the extension and retraction of the extension beam 11. The lower finger beam is composed of a lower finger beam 6 and a lower guide plate 29. The lower finger beams 6 are evenly welded on the inner beam 2 at equal intervals, and the interval between adjacent lower finger beams 6 meets the discharge requirement of the maximum drill string size as required by the design. The upper guide plate 30 is fixed on the upper finger beam 5, and the lower guide plate 29 is fixed on the lower finger beam 6. The upper guide plate 30 can slide in the middle of the lower guide plate 29 to guide the extension and retraction of the upper finger beam.

[0029] As Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, the finger beam latch 7 is composed of an electric cylinder 12, a split pin 13, a nut 14, an outer rotating shaft 15, a latch seat 16, a latch 17, a nut A 18, a clamping plate 19, and a rotating shaft 20. The lower end of the electric cylinder 12 is hinged to the upper finger beam 5 by a bolt and nut, and the other end is hinged to the outer rotating shaft 15. The latch seat 16 is fixed to the upper finger beam 5 by a bolt. The latch 17 is fixed in the latch seat 16 by the rotating shaft 20 and the clamping plate 19, and can rotate around the rotating shaft 20. A limiting plate is provided on the upper side of the latch seat 16 to prevent the latch 17 from rotating too much. The left side of the outer rotating shaft 15 is hinged to the electric cylinder 12 and is fixed by the nut 14 and the split pin 13. The right side passes through the latch seat 16 and the latch 17 and is fixed by the nut A 18 and the split pin 13. The outer rotating shaft 15 can drive the latch 17 to rotate around the rotating shaft 20.

[0030] As Figure 2 , Figure 4 , Figure 9 and Figure 10As shown, the positioning device 8 is composed of a limiting lug plate 21, a positioning pin shaft 22, a pin shaft 23, an electric cylinder A 24, a pin shaft A 25, and a lug plate A 26. The limiting lug plate 21 and the lug plate A 26 are welded on the lug plate 9, the bottom of the electric cylinder A 24 is hinged to the lug plate A 26 through the pin shaft A 25, and the top is hinged to the positioning pin shaft 22 through the pin shaft 23. After the positioning pin shaft 22 passes through the limiting lug plate 21, it can be extended and retracted in the limiting lug plate 21 under the driving of the electric cylinder A 24.

[0031] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the working principle of the double-layer finger beam adjustable two-layer table of the present application is that the control system 3 controls the oil cylinder 28 to adjust the upper finger beam 5 of the upper layer finger beam to be aligned with the lower finger beam 6 of the lower layer finger beam, and to be locked through the positioning device 8; when the drill string is arranged, the control system 3 controls the door latch 17 on the finger beam door latch 7 to be changed from the horizontal state to the vertical state, the door latch 17 is opened, and the drill string is sequentially arranged in the gap of the adjacent upper finger beam 5 under the action of the mechanical hand and other drill string processing tools, when the drill string is full, the control system 3 controls the door latch 17 on the finger beam door latch 7 to be changed from the vertical state to the horizontal state, the door latch 17 is closed, and the drill string arrangement is completed. Conversely, the drill string is taken out. When different sizes of drill strings need to be arranged, the control system 3 controls the oil cylinder 28 to drive the upper layer finger beam to move as a whole, so that the distance between the adjacent upper finger beam 5 and the corresponding lower finger beam 6 changes, the distance between the adjacent upper finger beam 5 becomes smaller, until the new drill string size requirement is met, the positioning device 8 is controlled to position and lock the upper layer finger beam, the adjustment of the distance between the finger beams is completed, and then the drill string is arranged;

[0032] As shown in Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 , the working principle of the finger beam door latch 7 is that the door latch seat 16 is provided with an arc-shaped long hole, the control system 3 controls the piston rod of the electric cylinder 12 to extend, drives the outer rotating shaft 15 to rotate in the arc-shaped long hole, and then drives the door latch 17 to rotate around the rotating shaft 20 until the door latch 17 is rotated from the horizontal state to the vertical state, and the door latch 17 is opened. Conversely, the door latch 17 is closed.

[0033] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10As shown, the limiting principle of the upper layer of the beam is that the telescopic beam 11 is provided with a limiting tube 27. When the telescopic beam 11 and the upper layer of the beam 5 are telescoped to the working position, the control system 3 controls the piston rod of the electric cylinder A24 to extend, drives the positioning pin shaft 22 to pass through the limiting lug plate 21 and then into the limiting tube 27, thereby fixing the position of the telescopic beam 11. When it is needed to control the upper layer of the beam to adjust the distance between the beams, the control system 3 controls the piston rod of the electric cylinder A24 to retract, drives the positioning pin shaft 22 to exit from the limiting tube 27, and then the telescopic adjustment movement of the telescopic beam 11 can be performed.

[0034] In the above manner, the two-layer table with adjustable beam can adjust the distance between the adjacent upper layer of the beam 5 through the telescoping of the upper layer of the beam, meet the requirements of discharging different diameter specifications of the drill string, has simple overall structure, convenient operation, economy and practicality, stable and reliable work, and effectively meets the needs of users for discharging multiple specifications of the drill string by using the same two-layer table.
