DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 4 As shown, a finger beam flap opening and closing device provided in this embodiment is applied to a two-layer platform system 100, comprising: a trigger mechanism 200, a finger beam flap 300, a rotating support 400, a telescopic body 500 and an elastic mechanism 600; the finger beam flap 300 is located on the rotating support 400, and the finger beam flap 300 is rotatably connected to the rotating support 400; the telescopic body 500 is inserted into the inside of the finger beam flap 300 through the rotating support 400, a spiral groove 301 is provided on the side wall of the finger beam flap 300, and a pushing part 501 for engaging with the spiral groove 301 is provided on the side wall of the telescopic body 500 The trigger mechanism 200 is connected to the manipulator 101 of the second-layer platform system 100. The manipulator 101 abuts against one end of the telescopic body 500 away from the elastic mechanism 600 through the trigger mechanism 200. The trigger mechanism 200 is used to drive the telescopic body 500 to move relative to the finger beam flap 300. The telescopic body 500 is used to drive the finger beam flap 300 to rotate relative to the rotating support 400 through the pushing part 501. One end of the telescopic body 500 away from the rotating support 400 is connected to the elastic mechanism 600. The elastic mechanism 600 has an elastic tendency to make the telescopic body 500 approach the finger beam flap 300.

[0036] It should be noted that the finger beam flap opening and closing device provided in this embodiment belongs to the finger beam structure of the second-level platform system 100 of the well repair equipment, wherein the opening and closing of the finger beam flap 300 is a simple and frequent action in the well repair operation, and the opening and closing action of the finger beam flap 300 is achieved by rotating the angle of the finger beam flap 300 so that the limiting protrusion 303 of the finger beam flap 300 can be in a horizontal closed state relative to the plane of the second-level platform system 100, or in a vertical open state relative to the plane of the second-level platform system 100.

[0037] In the present embodiment, when the trigger mechanism 200 is not in contact with the telescopic body 500, that is, when the trigger mechanism 200 does not apply a force to the telescopic body 500, the telescopic body 500 will move to the side away from the elastic mechanism 600 under the elastic tendency of the elastic mechanism 600. Since the telescopic mechanism utilizes the pushing portion 501 to engage with the spiral groove 301 of the finger beam flap 300, when the finger beam flap 300 is in a closed state, the pushing portion 501 abuts against the side of the spiral groove 301 away from the elastic mechanism 600. Furthermore, the extension direction of the spiral groove 301 is uniformly arranged along the circumferential direction of the finger beam flap 300. When the touch mechanism is in contact with the telescopic body 500, the touch mechanism is utilized to squeeze and drive the telescopic body 500. The retractable body 500 can overcome the elastic force of the elastic mechanism 600 and move along the inside of the finger beam flap 300 toward one side of the elastic mechanism 600. Since the pushing part 501 is engaged with the spiral groove 301, when the pushing part 501 moves along a straight line, the spiral groove 301 will drive the finger beam flap 300 to rotate relative to the rotating support 400 along its own spiral direction. When the trigger mechanism 200 drives the telescopic body 500 until the pushing part 501 abuts against the side of the spiral groove 301 close to the elastic mechanism 600, the finger beam flap 300 is in an open state. When the touch mechanism removes the force on the telescopic body 500, the telescopic body 500 will automatically close the finger beam flap 300 driven by the force of the elastic mechanism 600.

[0038] Optionally, the trigger mechanism 200 may adopt a trigger rod that cooperates with the telescopic body 500 .

[0039] The present embodiment provides a finger beam flap opening and closing device, which is applied to a two-layer platform system 100, and includes: a trigger mechanism 200, a finger beam flap 300, a rotating support 400, a telescopic body 500 and an elastic mechanism 600; the finger beam flap 300 is located on the rotating support 400, and the finger beam flap 300 is rotatably connected to the rotating support 400; the telescopic body 500 is inserted into the inside of the finger beam flap 300 through the rotating support 400, and a spiral groove 301 is provided on the side wall of the finger beam flap 300, and a pushing part 501 for engaging with the spiral groove 301 is provided on the side wall of the telescopic body 500; The trigger mechanism 200 is connected to the manipulator 101 of the second-layer platform system 100. The manipulator 101 is in contact with one end of the telescopic body 500 away from the elastic mechanism 600 through the trigger mechanism 200. The trigger mechanism 200 is used to drive the telescopic body 500 to move relative to the finger beam flap 300. The telescopic body 500 is used to drive the finger beam flap 300 to rotate relative to the rotating support 400 through the pushing part 501. The end of the telescopic body 500 away from the rotating support 400 is connected to the elastic mechanism 600. The elastic mechanism 600 has an elastic tendency to make the telescopic body 500 close to the finger beam flap 300; wherein When the finger beam flap 300 is in a closed state, the elastic mechanism 600 uses the telescopic body 500 to apply a force to the finger beam flap 300, so that the finger beam flap 300 remains in a closed state without its own driving force; when the finger beam flap 300 needs to be opened, the manipulator 101 of the second-level platform system 100 drives the trigger mechanism 200 to abut against the telescopic body 500, and drives the telescopic body 500 to overcome the elastic force of the elastic mechanism 600, so that the telescopic body 500 can move along the inside of the finger beam flap 300 to one side of the elastic mechanism 600, and at the telescopic body During the linear movement of the body 500, the pushing part 501 will move along the spiral groove 301 of the finger beam flap 300, so that the finger beam flap 300 can rotate relative to the rotating support 400, thereby realizing the opening operation of the finger beam flap 300 without its own driving force; there is no need to install an electric drive on the finger beam flap 300, which reduces the cost and realizes the closing by relying on its own elastic reset without external power; it alleviates the technical problems existing in the prior art that the finger beam flap 300 driven by electric drive is large in size, has many lines, high cost, poor reliability, high failure rate, and complex maintenance.

[0040] On the basis of the above embodiments, further, in a preferred embodiment of the present invention, the finger beam flap 300 includes a flap body 302 and a limiting protrusion 303; the flap body 302 is located on the rotating support 400, the limiting protrusion 303 is located at one end of the flap body 302 away from the elastic mechanism 600, and the limiting protrusion 303 is fixedly connected to the side wall of the flap body 302; there is a spacing between any two adjacent flap bodies 302, and the limiting protrusion 303 is located between any two adjacent flap bodies 302 to limit the opening and closing of the finger beam flap 300.

[0041] In this embodiment, the flap body 302 is a cylindrical structure, and the interior of the flap body 302 is a hollow structure, the telescopic body 500 completely penetrates the flap body 302, and the telescopic body 500 is clamped with the spiral groove 301 of the flap body 302 through the pushing part 501, and the flap body 302 is fixedly connected with the limiting protrusion 303, wherein the spiral angle of the spiral groove 301 can be 90°, that is, when the pushing part 501 abuts against one end of the spiral groove 301 away from the elastic mechanism 600, the flap body 302 drives the limiting protrusion 303 to be arranged horizontally, and when the pushing part 501 abuts against one end of the spiral groove 301 close to the elastic mechanism 600, the flap body 302 drives the limiting protrusion 303 to be set vertically, thereby utilizing the position of the limiting protrusion 303 to control the opening and closing state between any two adjacent command flaps.

[0042] In a preferred embodiment of the present invention, the rotating support 400 includes a first rotating support 401, a second rotating support 402 and a rotating bearing 403; the finger beam flap 300 is located between the first rotating support 401 and the second rotating support 402, and the two ends of the finger beam flap 300 are rotatably connected to the first rotating support 401 and the second rotating support 402 respectively through the rotating bearing 403; a first through hole is provided on the first rotating support 401, and a second through hole is provided on the second rotating support 402, and the telescopic body 500 passes through the second through hole, the interior of the finger beam flap 300 and the first through hole in sequence.

[0043] In this embodiment, the structures of the first rotating support 401 and the second rotating support 402 are the same, wherein the two ends of the finger beam flap 300 are rotatably connected to the first rotating support 401 and the second rotating support 402 through the rotating bearing 403 respectively, and the telescopic body 500 can be respectively moved through the first through hole of the first rotating support 401 and the second through hole of the second rotating support 402, and the telescopic body 500 can reciprocate in the first through hole and the second through hole; wherein the outer diameter of the end of the trigger mechanism 200 is smaller than the inner diameter of the first through hole.

[0044] Optionally, the first rotating support 401 and the second rotating support 402 are located on a straight line, and the first rotating support 401 and the second rotating support 402 are respectively fixedly connected to the plane of the second-layer platform.

[0045] In a preferred embodiment of the present invention, the telescopic body 500 also includes a telescopic rod 502 and a sliding mechanism 503; the telescopic rod 502 is arranged to penetrate the interior of the finger beam flap 300, and one end of the telescopic rod 502 extends out of the second rotating support 402 and is fixedly connected to the sliding mechanism 503, and the sliding mechanism 503 is in contact with the elastic mechanism 600, and the elastic mechanism 600 enables the telescopic rod 502 to have an elastic tendency to approach the finger beam flap 300 through the sliding mechanism 503.

[0046] In a preferred embodiment of the present invention, the sliding mechanism 503 includes a slider 513 and a slide groove 523; the slide groove 523 is fixedly connected to the upper plane of the rectangular inner hole of the finger beam of the second-layer platform system 100, the slider 513 and the slide groove 523 are slidably connected, one side of the slider 513 is fixedly connected to the telescopic rod 502, and the other side of the slider 513 abuts against the elastic component 602.

[0047] In this embodiment, the telescopic rod 502 is fixedly connected to the slider 513, and the slider 513 is used to realize reciprocating sliding on the slide groove 523. Since the slider 513 can only move along the trajectory defined by the slide groove 523, the slide groove 523 is fixedly connected to the rectangular inner hole of the finger beam of the second-layer platform system 100, and the extension direction of the slide groove 523 is in a straight line with the extension direction of the finger beam flap 300. The limitation of the slider 513 ensures that the telescopic rod 502 moves along a straight line and limits the axial rotation of the telescopic rod 502. Then, the spiral groove 301 is used to push the finger beam flap 300 circumferentially relative to the first rotating support 401 and the second rotating support 402.

[0048] In a preferred embodiment of the present invention, the pushing portion 501 includes a pushing rod 511 and a rotating wheel 521; the pushing rod 511 is arranged perpendicular to the extension direction of the telescopic rod 502, and the pushing rod 511 is connected to the telescopic rod 502, the rotating wheel 521 is sleeved on the outside of the pushing rod 511, and the rotating wheel 521 can rotate around the pushing rod 511, the rotating wheel 521 is clamped in the spiral groove 301 of the finger beam flap 300, and the pushing rod 511 is used to drive the rotating wheel 521 to move along the extension direction of the spiral groove 301.

[0049] In this embodiment, since the push rod 511 is fixedly connected to the telescopic rod 502, when the telescopic rod 502 moves back and forth in the horizontal direction, the push rod 511 will directly contact the inner wall of the spiral groove 301, and the spiral groove 301 will rotate. In order to reduce the friction force between the push rod 511 and the inner wall of the spiral groove 301, a rotating wheel 521 is provided on the outside of the push rod 511. When the spiral groove 301 rotates, the rotating wheel 521 will rotate with the push rod 511 as the center, and the rotating wheel 521 will rotate along the inner wall of the spiral groove 301, thereby reducing the direct friction force between the push part 501 and the spiral groove 301, making the design more perfect.

[0050] In a preferred embodiment of the present invention, the elastic mechanism 600 includes a fixed bracket 601 and an elastic component 602; the fixed bracket 601 is fixedly connected to the plane of the second-layer platform system 100, one end of the elastic component 602 abuts against the fixed bracket 601, and the other end of the elastic component 602 abuts against the sliding mechanism 503, and the telescopic rod 502 is used to compress the elastic component 602 through the sliding mechanism 503.

[0053] In this embodiment, the slider 513 is connected to the guide rod 622, and the guide rod 622 can ensure that the compression spring 612 remains stable within the limited area of ​​the slider 513 and the fixed bracket 601; and the fixed bracket 601 is provided with a third through hole through which the guide rod 622 passes, and the fixed bracket 601 not only plays a role in fixing the compression spring 612, but also ensures that the guide rod 622 can shuttle back and forth in the third through hole;

[0054] Specifically, the finger beam flap 300 will be in a closed state under the elastic action of the compression spring 612 itself, when the trigger mechanism 200 pushes the telescopic rod 502 to move in the direction of the second rotating support 402 through the first through hole of the first rotating support 401; the telescopic rod 502 pushes the slider 513 along the slide groove 523 to squeeze the compression spring 612 toward the fixed bracket 601, and the guide rod 622 moves in the direction away from the fixed bracket 601 through the third through hole of the fixed bracket 601.
