As shown in Figures 1, 2, and 3, the rack and pinion drilling tool transfer device includes: vertical frame, driving device 3, pushing device, anti-skid device 5, unloading device 6, support arm 4, rotating arm 8, rotating arm Base 10, backing plate 9, base plate 11; The driving device 3 is connected to the vertical frame and hinged with the support arm 4; The pushing device, anti-skid device 5 and unloading device 6 are installed on the On the supporting arm 4; the rotating arm 8 is connected with the supporting arm 4 and hinged with the rotating arm base 10; the backing plate 9 is used to support the rotating arm 8; the base plate 11 is a support And the bottom plate that fixes the whole device.

As shown in Figures 1, 2, and 3, the specific implementation steps of a rack and pinion drilling tool transfer device of the present invention are as follows:

At the beginning, the drilling tool is discharged in the compartment of the transport vehicle. When everything is ready, the manual slowly rolls the drilling tool into the V-shaped groove of the support arm 4. Under blocking, the drilling tool will not rush out of the V-shaped groove, and then control the hydraulic cylinder of the movable anti-skid device 51 of the anti-skid device 5, and the movable retaining column will slowly rise to prevent the drilling tool from rolling out of the support arm 4 during the transfer process. V-shaped groove; after confirming that the drilling tool is placed stably, the three-phase asynchronous motor 31 starts to work, and through the deceleration transmission of the worm 32 and the worm gear 33, the gear 34 meshes with the rack 2, and drives the driving device 3 and the support arm 4 upward together Movement, as one end of the support arm 4 rises slowly, the rotating arm 8 also rotates correspondingly, therefore, the support arm 4 moves upward as a whole; when lifting to a predetermined position, the three-phase asynchronous motor 31 stops rotating, due to the 32 self-locking, the support arm 4 is still, at this time, the push motor 12 starts to move, after being decelerated by the push reduction box 14, the drum 13 starts to wind the wire rope, the wire rope is connected with the movable pulley 15, and the movable pulley 15 is fixedly connected with the push plate 7, pushing The action of the motor 12 is finally converted to the oblique upward movement of the push plate 7 along the V-shaped groove of the support arm 4, and then plays the role of pushing the drilling tool upward; , precisely placed on the station; when the drilling tool is disassembled and recovered, it is first put into the V-shaped groove of the support arm 4 by the manipulator of the drilling platform, and the drilling tool slides obliquely downward under the action of gravity, and at the same time Push the push plate 7 back, and the push plate 7 plays a role of buffer protection during this process. When the drilling tool slides to the end of the V-shaped groove of the support arm 4, the three-phase asynchronous motor 31 runs in reverse, and the gear 34 runs along the gear The bar 2 moves downwards, and at the same time drives the support arm 4 to fall back until it reaches the initial position of the work, and the support arm 4 stops moving smoothly; The column is lowered, and the piston rod of the unloading hydraulic cylinder of the unloading device 6 is extended to push the unloading push plate fixedly connected with it, so that the drilling tool rolls out of the V-shaped groove and enters the compartment of the transport vehicle, and the unloading is completed. During the whole process, the self-locking performance of the worm gear 33 and the worm screw 32 ensures that the support arm 4 will not fall back suddenly when the whole device is suspended or in an unexpected power failure, causing danger, improving the safety performance and ensuring the safety of the staff.
