the integrated hydraulic source multi-drill throwing power catwalk has the following main components:
the base 1 is an installation foundation of the whole power catwalk, is provided with a lifting lug for dismounting and is placed at a proper position on the ground at the front end of the drilling machine. The base 1 is of a closed structure, the two sides of the base are provided with valves, the internal mechanism is convenient to overhaul, the upper part of the base is provided with a cover plate, and the upper part of the hydraulic station 20 is provided with a movable cover plate, so that the integrated hydraulic station 20 is convenient to install and overhaul. When the drill rods are conveyed to a drill floor, the tilting mechanism 3 on one side synchronously lifts the tilting mechanism turnover plate 3-1 inwards under the action of the tilting mechanism oil cylinder 3-2 to deliver the drill rods on the pipe rack 2 to the drill sending column device 17 one by one, and then the drill sending column device 17 conveys the drill rods to the drill floor. When a plurality of drill throwing operations are carried out, the drill throwing pulley assembly 19 slides along the upper plane of the base 1, and when the drill rods are dragged to be parallel to the base 1, the tilting mechanisms 3 on the two sides synchronously lift outwards to turn the drill rods to the pipe rack 2 on the two sides.

The pipe rack 2 at the left side and the right side of the base 1 inclines outwards by 3 degrees to 5 degrees, so that the drill rods can roll out of the pipe rack 2 conveniently.
And step b, under the action of the driving hydraulic cylinder 11 and the steel wire rope 14, the four drill throwing hook rods 8 on the two sides of the ramp 4 slide upwards along the sliding guide rail b7 to the highest position and then stop, and the jigger 18 drives the drill throwing tackle assemblies 19 on the two sides to advance to a proper position to stop, wherein the position is determined by the position set in the encoder of the jigger 18.
And c, respectively sending the four drill rods to the corrugated plates 5 on the two sides of the ramp 4 by using other auxiliary tools such as a drill floor manipulator or a pneumatic winch and the like, and sliding the drill rods downwards along the corrugated plates 5 to be in contact with the rubber buffer pads a9 in the drill throwing hook rod 8. At the moment, the four drill rods are in a static state, the drill rod body is completely leaned on and placed on the V-shaped groove of the corrugated plate 5, the lower end of the drill rod body is limited by the drill throwing hook rod 8, and the hydraulic cylinder 11 is driven to be in a complete retraction state.

The multiple-drill throwing power catwalk with the integrated hydraulic source is characterized in that the drill throwing pulley assembly (19) comprises a connecting frame (19-1), one end of the connecting frame (19-1) is connected to a small pulley (18), the other end of the connecting frame (19-1) is connected with one end of a pulley body (19-2), the bottom of the pulley body (19-2) is provided with four rollers b (19-8), the other end of the pulley body (19-2) is connected with a slotted bracket (19-3), a rubber cushion b (19-5) is installed on the slotted bracket (19-3) in the vertical direction, and the front surface and the back surface of the slotted bracket (19-3) in the horizontal direction are respectively provided with a slotted friction plate (19-4);
the two opposite sides of each slotted bracket (19-3) are respectively provided with a safety baffle (19-6), and one end of each slotted bracket (19-3) far away from the rubber cushion b (19-5) is also provided with a pulley supporting plate (19-7).
5. The multiple-drill throwing power catwalk with the integrated hydraulic source is characterized in that the pulley support plates (19-7) are vertically arranged on the slotted brackets (19-3), and the upper end faces of the pulley support plates (19-7) are provided with openings, wherein the shapes of the openings are matched with the radian of the neck of a drill pipe male joint.
6. A one-key multi-throwing operation method for a multi-throwing drill power catwalk of an integrated hydraulic source according to any one of claims 1-5, which is implemented by the following steps:
step 1, before throwing multiple roots, the whole device is in an initial standby position, a drill feeding column device (17) is lowered to the lowest initial position, namely the whole multiple roots throwing operation process does not need the drill feeding column device (17) to be lifted and lowered, a jigger (18) is retreated to the rearmost end of the drill feeding column device (17), two drill throwing pulley assemblies (19) are connected and fixed on the left side and the right side of the jigger (18), and pipe racks (2) on the left side and the right side of a base (1) are inclined outwards by 3-5 degrees so that drill rods can be conveniently rolled out of the pipe racks (2);
step 2, under the action of a driving hydraulic cylinder (11) and a steel wire rope (14), four drill throwing hook rods (8) on two sides of the ramp (4) slide upwards along a sliding guide rail b (7) to the highest position and then stop, and a small pulley (18) drives drill throwing pulley assemblies (19) on two sides to advance to the position set in the encoder and then stop;
step 3, respectively sending the four drill rods to corrugated plates (5) on two sides of the ramp (4), and enabling the drill rods to slide downwards along the corrugated plates (5) and to be in contact with rubber cushion pads a (9) in a drill throwing hook rod (8); at the moment, the four drill rods are in a static state, the drill rod body is completely leaned against the V-shaped groove of the corrugated plate (5), the lower ends of the four drill rods are limited by the drill throwing hook rod (8), and the driving hydraulic cylinder (11) is in a completely retracted state;
step 4, executing one-key drill throwing, simultaneously extending cylinder rods of driving hydraulic cylinders (11) at two sides of the ramp (4), simultaneously sliding and descending the four drill throwing hook rods (8) and drill rods along a sliding guide rail b (7) under the driving of the driving hydraulic cylinders (11) and a steel wire rope (14), determining the final descending position of the drill throwing hook rods (8) by a stroke set in a displacement sensor of the driving hydraulic cylinders (11), completely falling the four drill rods onto a drill throwing pulley assembly (19) in the final state, descending the drill throwing hook rods (8) below the drill throwing pulley assembly (19), and separating the drill rods from the drill throwing hook rods (8); after the drill throwing hook rod descends to the right position, a hydraulic cylinder (11) is driven to feed back a signal by a displacement sensor, a small pulley (18) encoder is triggered to receive the signal, the small pulley (18) starts to automatically drive the drill throwing pulley assemblies (19) on two sides to retreat, in the retreating process, the four drill rods change from the inclined state of the ramp corrugated plate (5) into the horizontal state by means of gravity and friction force with a friction plate (19-4) and are separated from the corrugated plate (5), the small pulley (18) continuously retreats to a proper position to stop, and the four drill rods are not separated from the drill throwing pulley assemblies (19) under the action of a pulley supporting plate (19-7);
and 5, after the jigger (18) and the drill throwing tackle assembly (19) are in place, feeding back signals by an encoder of the jigger (18), triggering the tilting mechanisms (3) on the two sides of the base (1), automatically inclining the tilting plates (3-1) of the tilting mechanisms outwards simultaneously under the action of the tilting mechanism oil cylinders (3-2), turning out the drill rods on the two sides onto the pipe rack (2) on the left side and the right side, and completing four operation flows of automatic one-key throwing.
