Description

Technical Field

[0001] This invention relates to the field of machinery and equipment for oil drilling, and in particular to a sleeve wire unloading device. Background Technology

[0002] As drilling continues to explore and advance into deeper ground, drilling depths are constantly increasing, leading to a significant increase in the number of casing sections run into the open hole. When operators are installing and removing casing and wire sheathing on-site, the process is challenging because the installation and removal of the casing and wire sheathing is done by machine at the factory, which has a certain torque. Therefore, on-site installation and removal requires multiple people to manually disassemble the casing and wire sheathing using levers and wrenches. This results in high labor intensity, low work efficiency, and significant safety risks. In recent years, personal injury incidents and safety accidents caused by improper coordination during casing and wire sheathing removal have been increasing. Therefore, how to quickly and conveniently install and remove the wire sheathing on-site is a key research focus. Summary of the Invention

[0003] To address the above problems, the present invention provides a sleeve wire unloading device, which has the advantages of simple structure, fast unloading, and safety.

[0004] The technical solution of this invention is:

[0005] A sleeve wire unloading device includes a torque sleeve, a transition plate, a torque plate and multiple jaws connected coaxially in sequence.

[0006] The torque sleeve and the transition plate are connected by a first connecting rod, one end of which is hinged to the torque sleeve and the other end is fixedly connected to the transition plate.

[0007] The transition plate is fixedly connected to the torque plate;

[0008] The torque disc has multiple arc-shaped through holes with a corresponding number of claws evenly distributed along its axial direction as the rotation direction. A connecting pin is slidably provided in each arc-shaped through hole, and each connecting pin is hinged to one of the claws.

[0009] The chuck includes a torsion bar and jaws. One end of the torsion bar is hinged to a connecting pin, and the other end is hinged to the jaws.

[0010] The number of the first connecting rods is four. The torque sleeve has connecting lugs evenly distributed with its axis as the center of rotation, corresponding to the number of the first connecting rods. A first connecting pin is provided at the connecting lug, and a second connecting pin is provided at the hinge point between the first connecting rod and the transition plate.

[0011] The transition plate and the torque plate are fixedly connected by a second connecting pin.

[0012] The number of grippers is four.

[0013] The clamp teeth include a tooth body and a connecting seat that is hinged to a torsion bar, wherein the connecting seat is a V-shaped seat.

[0014] The beneficial effects of this invention are:

[0015] The torque sleeve drives the transition plate and the torque plate to rotate. Under centrifugal force, the jaws of the chuck engage with the inner wall of the wire guard, quickly completing the loading and unloading operation. It does not require multiple people to cooperate, which can effectively improve loading and unloading efficiency, reduce operational risks, ensure the safe operation of the enterprise, and reduce the risk of personal injury and equipment damage.

Detailed Implementation

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] like Figures 1-6 As shown, a sleeve wire unloading device includes a torque sleeve 1, a transition plate 2, a torque plate 3 and multiple claws 4 connected coaxially in sequence.

[0027] The torque sleeve is connected to the transition plate 2 via the first connecting rod 11. One end of the first connecting rod 11 is hinged to the torque sleeve 1, and the other end is fixedly connected to the transition plate 2.

[0028] Transition plate 2 is fixedly connected to torque plate 3;

[0029] The torque disc 3 has multiple arc-shaped through holes 31 with a corresponding number of claws 4 evenly distributed in the direction of rotation of its axis. Each arc-shaped through hole 31 is provided with a slidable connecting pin 32, and each connecting pin 32 is hinged to a claw 4.

[0030] The chuck 4 includes a torsion bar 41 and jaws 42. One end of the torsion bar 41 is hinged to the connecting pin 32, and the other end is hinged to the jaws 42.

[0031] The working principle of the above technical solution is as follows:

[0032] When it is necessary to install or remove the sleeve wire protector 5, connect the torque sleeve 1 to the storm machine and rotate the torque sleeve 1. Since the torque sleeve 1 is hinged to the transition plate 2 through the first connecting rod 11, it will drive the transition plate 2 to rotate. The transition plate 2 is fixedly connected to the torque plate 3, which in turn drives the torque plate 3 to rotate. The torque plate 3 has multiple arc-shaped through holes 31. Each arc-shaped through hole 31 is hinged to a claw 4 through a connecting pin 32. When rotating, under the action of centrifugal force, the connecting pin 32 slides in the arc-shaped through hole 31, and the claw 4 slides out in the arc-shaped through hole 31. The jaws 42 at the front end of the claw 4 engage with the inner wall of the wire protector, realizing the disassembly and installation of the sleeve wire protector. Depending on the installation or disassembly needs, the torque sleeve 1 can be rotated clockwise or counterclockwise. The arc-shaped through hole 31 plays the role of upper and lower limit, which can be adapted to various different wire protector 5 installation and removal operations.

[0033] The number of first connecting rods 11 is four. The torque sleeve 1 has connecting lugs 12 evenly distributed with its axis as the rotation center, corresponding to the number of first connecting rods 11. A first connecting pin 13 is set at the connecting lug 12. A second connecting pin 14 is set at the hinge point between the first connecting rod 11 and the transition plate 2. By setting the lugs, the torque sleeve 1 and the transition plate 2 are hinged, which can increase the torque and improve the loading and unloading efficiency.

[0034] The transition plate 2 and the torque plate 3 are fixedly connected by the second connecting pin 14. The second connecting pin 14 also fixes the transition plate 2 and the torque plate 4. The structure is simple, easy to assemble, and convenient for on-site loading and unloading.

[0035] The number of four chucks is even, which ensures the stability of the sleeve wire protector loading and unloading.

[0036] The clamp 42 includes a tooth body 421 and a connecting seat 422 hinged to the torsion bar 41. The connecting seat 422 is a V-shaped seat, which can automatically align and adaptively increase the biting area with the sleeve wire.

[0037] Safety pins are provided on both sides of the connecting pin at the hinge point between the jaw 42 and the torsion bar 41 to prevent the jaw from automatically disengaging when it wears out, and to facilitate the replacement of the jaw.

[0038] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
