Thus, when the shuttle 121 pushes the pipe 100 to move forward to abut against the lower end of the ramp 21, the pulley 221 can be driven by the second driving member 222 to move up along the ramp 21 so as to drive the front end of the pipe 100 to move up together, and after the pipe 100 abuts against the ramp 21 again, the pulley 221 is driven by the second driving member 222 to move down to the initial position so that the shuttle 121 continues to push the pipe 100 to the upright state, thereby realizing that the lifting mechanism 22 lifts one end of the pipe 100 on the ramp 21.

Optionally, as shown in conjunction with fig. 3, the power catwalk further includes a first limit mechanism 3, where the first limit mechanism 3 is used to limit the movement travel of the shuttle 121 in the V-shaped groove 111.

In this way, the rack 131 is supported by the support 135, and the stability of the rack mechanism 13 when supported on the ground is ensured.

Optionally, as shown in connection with fig. 2, the calandria mechanism 13 further includes a striker pin 134, and an end of the calandria 131 remote from the base 11 is provided with a striker pin hole, and the striker pin 134 is inserted into the striker pin hole.

In this way, blanking pins 134 may be utilized to block the pipe tool 100 from rolling off the rake 131.

Alternatively, as shown in fig. 1 and 4, the upper end surface of the base 11 is provided with the deck 113, the deck 113 is located on one side or both sides of the V-shaped groove 111, and one end of the deck 113 away from the V-shaped groove 111 extends downward in a direction away from the V-shaped groove 111.

Specifically, the upper end surface of the base 11 is generally provided with a plurality of planks 113, and the planks 113 are sequentially laid along the length direction of the base 11, and when the rake 131 is provided on both the left and right sides of the base 11, the planks 113 are laid on both the left and right sides of the V-shaped groove 111, and when the rake 131 is provided on either the left or right side of the base 11, the planks 113 are laid on either the left or right side of the V-shaped groove 111. Also, the end of the deck 113 near the V-shaped groove 111 extends to the edge of the V-shaped groove 111, and the end of the deck 113 away from the V-shaped groove 111 is disposed obliquely downward.

Further, referring to fig. 4, the rake 131 is inclined, and the inclination angle of the rake 131 is the same as that of the decking 113.

Thus, the planking 113 and the rake 131 form a slope structure on both sides of the V-shaped groove 111, and the pipe 100 can smoothly roll down the slope structure onto the rake 131 after being kicked out of the V-shaped groove 111, and is placed side by side in sequence from the stop pin 134 on the rake 131 without being retained at one end of the rake 131 near the base 11.

In this embodiment, the telescopic mechanism 5 is preferably an electric cylinder to perform the telescopic function, however, in other embodiments, the telescopic mechanism 5 may be a hydraulic cylinder, and the telescopic mechanism 5 is usually disposed at the left side or the right side of the ramp 21, so as to avoid preventing the trolley 221 from lifting or preventing the pipe tool 100 from moving in the V-shaped groove 111. When the ramp 21 is erected at the front end of the base 11, the telescopic mechanism 5 is in an extending state, and after the power catwalk finishes the operation, the ramp 21 can be driven to rotate and fold onto the base 11 through the telescopic mechanism 5 in a shrinkage motion, so that the transportation is convenient.

Optionally, as shown in connection with fig. 1, the power catwalk further comprises a pull rod mechanism 6 arranged obliquely, and one end of the pull rod mechanism 6 is used for being connected to the ramp 21, and the other end is used for being connected to the base 11.

In this embodiment, the pull rod mechanism 6 and the telescopic mechanism 5 are respectively located at the left and right sides of the ramp 21, the ramp 21 is mainly supported at the front end of the base 11 through the telescopic mechanism 5, the pull rod mechanism 6 is used for supporting the ramp 21 in an auxiliary manner, before the ramp 21 is folded on the base 11, the pull rod mechanism 6 needs to be detached, and after the ramp 21 is lifted to be erected at the front end of the base 11 through the telescopic mechanism 5, the pull rod mechanism 6 is assembled on the ramp 21 and the base 11 so as to support the ramp 21 together with the telescopic mechanism 5, thereby improving the stability of the ramp 21 when being erected at the end of the base 11.

Further, as shown in fig. 1, the power catwalk further includes an electric control system 7, the first driving member 122 and the second driving member 222 are electric winches, the first telescopic cylinder, the second telescopic cylinder, the third telescopic cylinder 152 and the fourth telescopic cylinder are electric cylinders, and the electric control system 7 is used for controlling the start and stop of each electric winch and each electric cylinder. Therefore, pure electric driving is realized, and efficiency and convenience in the process of delivering and throwing the drill are improved.

The working principles of the drill feeding and the drill throwing will be described with reference to specific examples, in which four first proximity switches in fig. 3 are sequentially called a No. 1 proximity switch, a No. 2 proximity switch, a No. 3 proximity switch and a No. 4 proximity switch from front to back, a second proximity switch in fig. 3 located at the lower end of the ramp 21 is called a No. 5 proximity switch, a second proximity switch located at the upper end of the ramp 21 is called a No. 6 proximity switch, in an initial state, the shuttle car 121 is stopped at the No. 4 proximity switch, and the trolley 221 is stopped at the No. 5 proximity switch.

When the drill is fed, the first telescopic cylinder 132 lifts the pipe rack 131, so that the pipe tool 100 on the pipe rack 131 rolls to the position of the material distributing pin 114 on the base 11, then the pipe tool 100 is turned into the V-shaped groove 111 by the pipe feeding mechanism 14, the first driving piece 122 drives the shuttle car 121 to move forward so as to push the pipe tool 100 to move forward, when the shuttle car 121 senses the No. 3 proximity switch, the shuttle car 121 stops, and at the moment, the front end of the pipe tool 100 is propped against the lower end of the ramp 21 and is placed on the pulley 221, as shown in fig. 5; then, the pulley 221 is driven to move up the ramp 21 by the second driving member 222, so as to drive the front end of the pipe 100 to move up, so that the pipe 100 is inclined, and when the pulley 221 senses the No. 6 proximity switch, the pulley 221 stops, as shown in fig. 6; the first driving member 122 drives the shuttle 121 to move forward, so as to push the pipe 100 to move forward continuously until the shuttle 121 senses the No. 2 proximity switch and stops, at this time, the front end of the pipe 100 abuts against the ramp 21 again, as shown in fig. 7; the second driving member 222 drives the pulley 221 to descend along the ramp 21 until the pulley 221 senses the No. 5 proximity switch to stop, at this time, the pulley 221 returns to the initial position, and the first driving member 122 drives the shuttle 121 to move forward to push the pipe 100 to continue advancing until the shuttle 121 senses the No. 1 proximity switch to stop, as shown in fig. 8, at this time, the pipe 100 is in a substantially upright state and passes through the mousehole 210 from below the drilling floor 200, and the height of the pipe 100 exposed out of the drilling floor 200 is sufficient, so that the driller can operate the elevator to directly connect the drilling row for next operation. In addition, for a drilling machine with a higher drilling platform 200, the pipe 100 does not pass through the rat hole 210 when standing upright, and the pulley 221 is required to drive the pipe 100 to vertically rise until the pipe 100 is exposed out of the drilling platform 200 to perform drilling.

When the drill is thrown, the shuttle car 121 is in idle running to the position of the No. 1 proximity switch, and the pulley 221 is positioned at the position of the No. 5 proximity switch; after the pipe 100 is lowered onto the shuttle 121 from the mouse hole 210, the shuttle 121 is driven to move backwards through the first driving piece 122 so as to drive the pipe 100 to retreat until the shuttle 121 senses the No. 2 proximity switch, and then the pulley 221 is driven to ascend through the second driving piece 222 until the pulley 221 senses the No. 6 proximity switch; the shuttle car 121 is driven to move backwards through the first driving piece 122 so as to drive the pipe tool 100 to continuously retreat until the shuttle car 121 senses the No. 3 proximity switch, and the trolley 221 is driven to move downwards through the second driving piece 222 until the trolley 221 senses the No. 5 proximity switch; then the shuttle car 121 is driven to move backwards through the first driving piece 122 so as to drive the pipe tool 100 to continuously retreat until the shuttle car 121 senses the No. 4 proximity switch and stops, and at the moment, the pipe tool 100 returns to the initial position; the pipe tool 100 in the V-shaped groove 111 is kicked out through the pipe outlet mechanism 15, so that the pipe tool 100 rolls onto the pipe rack 131 along the inclined planking 113 on the base 11 (the pipe inlet mechanism 14 is in an initial state, and the material distributing pins 114 on the base 11 are pulled out).

Although the present disclosure is described above, the scope of protection of the present disclosure is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the scope of the utility model.
