Description

Technical Field

[0001] The utility model relates to the technical field of anti-eccentric wear of sucker rods, in particular to a coupling make-up and break-out machine for anti-eccentric wear of sucker rods. Background Art

[0002] The sucker rod is a slender rod of a pumping well. It is connected to a bare rod at the top and a pump at the bottom to transmit power. A clamp needs to be installed on the sucker rod during installation, and existing sucker rod couplings are all anti-eccentric wear.

[0003] After searching, a Chinese patent discloses a sucker rod anti-wear coupling make-up and make-up machine, and its authorization announcement number is (CN213807601U), which includes a connecting seat installed on the make-up and make-up machine body, and the bottom of the connecting seat is provided with a rotating groove, and the connecting seat above the rotating groove is provided with a mounting cavity, and a movable tube is movably installed in the rotating groove, and the top of the movable tube slides through the mounting cavity and is movably sleeved with a fixed guide rod, and the top of the fixed guide rod is fixed on the top inner wall of the mounting cavity.

[0004] This patented technology drives the two clamping plates to rotate through the teeth on the outside of the movable tube and the gear, thereby clamping and fixing the annular anti-eccentric wear coupling. However, in actual use, a screw motor is used as the driving source, so when the two clamping plates clamp the anti-eccentric wear coupling, the clamping force is unclear. Different specifications and models of anti-eccentric wear couplings have different pressure resistance, which can easily damage the anti-eccentric wear coupling, thereby reducing the practicality of the device. In this way, in response to the above problems, we have launched a sucker rod anti-eccentric wear coupling buckle-off machine. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide an assembled temporary airport pavement and pavement panel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sucker rod anti-wear coupling unloading machine comprises a connecting frame seat, wherein a first clamping seat and a second clamping seat are slidably connected inside the connecting frame seat, a first receiving groove is opened on one side of the first clamping seat, and a second receiving groove is opened on one side of the second clamping seat, a displacement component is arranged inside the connecting frame seat for driving the first clamping seat and the second clamping seat to move closer to or away from each other, a second clamping roller is rotatably connected inside the second receiving groove, and a third receiving groove is also opened on one side of the second clamping seat, a fine-tuning component is arranged inside the third receiving groove for driving the second clamping roller to rotate, a U-shaped plate is slidably connected inside the first receiving groove, and the first clamping roller is rotatably connected inside the U-shaped plate, a force sensor is fixedly installed between one side of the inner wall of the first receiving groove and the U-shaped plate, and four mounting blocks are provided on the top of the connecting frame seat.

[0009] In a preferred solution, both sides of the inner wall of the first containing groove are provided with sliding grooves, and both ends of the U-shaped plate are provided with sliding blocks, and the sliding blocks are slidably connected inside the sliding grooves.

[0010] In a preferred solution, two connecting rods are slidably connected inside the first clamp seat, a side plate is provided between one ends of the two connecting rods, and the other ends of the connecting rods are fixedly connected to the U-shaped plate.

[0011] In a preferred embodiment, the displacement assembly includes a servo motor, which is fixedly mounted on one side of a connecting frame seat. A bidirectional screw rod is rotatably connected inside the connecting frame seat. The first clamp seat and the second clamp seat are respectively threadedly connected to the two ends of the outer side of the bidirectional screw rod.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0022] Example 1

[0023] Reference Figures 1 to 4 , a sucker rod anti-bias wear coupling buckling machine, including a connecting frame seat 1, the connecting frame seat 1 is internally slidably connected with a first clamping seat 2 and a second clamping seat 3, a first receiving groove 6 is provided on one side of the first clamping seat 2, and a second receiving groove 14 is provided on one side of the second clamping seat 3. A displacement component for driving the first clamping seat 2 and the second clamping seat 3 to move closer to or away from each other is arranged inside the connecting frame seat 1, a second clamping roller 15 is rotatably connected inside the second receiving groove 14, and a third receiving groove 16 is also provided on one side of the second clamping seat 3, and a fine-tuning component for driving the second clamping roller 15 to rotate is arranged inside the third receiving groove 16, a U-shaped plate 8 is slidably connected inside the first receiving groove 6, and a first clamping roller 13 is rotatably connected inside the U-shaped plate 8, a force sensor 7 is fixedly installed between one side of the inner wall of the first receiving groove 6 and the U-shaped plate 8, and four mounting blocks 20 are provided on the top of the connecting frame seat 1.

[0024] In the above technical solution, the anti-wear collar is placed between the first clamping roller 13 and the second clamping roller 15, and then the first clamping seat 2 and the second clamping seat 3 are driven to approach each other through the displacement assembly, and then the anti-wear collar is clamped and fixed by the first clamping roller 13 and the second clamping roller 15. When the first clamping roller 13 abuts against the outer side of the anti-wear collar, the first clamping seat 2 and the second clamping seat 3 continue to move, and the first clamping roller 13 drives the U-shaped plate 8 to move away from the second clamping roller 15. A force sensor 7 (whose model can be XJC-Y02-4M) is set between the U-shaped plate 8 and the first containing groove 6, so the force sensor 7 will be squeezed, thereby transmitting the signal to the external display, and then the clamping force can be understood, so as to be applicable to anti-wear collars of different sizes. After the anti-wear collar is fixed, the fine-tuning assembly is used to drive the second clamping roller 15 to rotate, thereby driving the anti-wear collar to displace and fine-tune it so that its position is in the center.

[0025] Example 2

[0026] Reference Figure 4 The fine-tuning assembly includes two L-shaped plates 19, which are fixedly connected to the two sides of the second clamping seat 3, respectively. A worm 18 is rotatably connected between the two L-shaped plates 19, and a worm wheel 17 is rotatably connected inside the third receiving groove 16. The worm wheel 17 and the second clamping roller 15 share the same rotating shaft, and the worm 18 and the worm wheel 17 are meshed with each other. By setting the fine-tuning assembly, the worm 18 is rotated to drive the worm wheel 17 to rotate, and the worm wheel 17 and the second clamping roller 15 share the same rotating shaft, and at the same time drive the second clamping roller 15 to rotate. Since the worm wheel 17 and the worm 18 have a self-locking effect, after the first clamping roller 13 and the second clamping roller 15 fix the anti-eccentric wear coupling, as long as the worm 18 does not rotate, the second clamping roller 15 will not rotate either, so that the clamping and fixing effect can be achieved, and then the position of the anti-eccentric wear coupling can be fine-tuned.

[0027] Reference Figure 3 , both sides of the inner wall of the first containing groove 6 are provided with a slide groove 10, and both ends of the U-shaped plate 8 are provided with a slider 9, and the slider 9 is slidably connected inside the slide groove 10. By setting the slide groove 10 and the slider 9 that cooperate with each other, the two sliders 9 slide inside the slide groove 10, so that the displacement of the U-shaped plate 8 is limited by the slider 9, so that it can translate inside the first containing groove 6.

[0028] Reference Figure 3 The first clamping seat 2 is internally slidably connected to two connecting rods 11, one end of the two connecting rods 11 is provided with a side plate 12, and the other end of the connecting rod 11 is fixedly connected to the U-shaped plate 8. By providing two connecting rods 11, the first clamping roller 13 moves to drive the two connecting rods 11 to slide inside the first clamping seat 2, so that the connecting rod 11 is used to guide the first clamping roller 13, and at the same time cooperates with the side plate 12 to prevent the U-shaped plate 8 from leaving the first receiving groove 6.

[0029] Reference Figure 2 and Figure 4 The displacement assembly includes a servo motor 4, which is fixedly mounted on one side of the connecting frame seat 1. The connecting frame seat 1 is internally rotatably connected with a bidirectional screw rod 5. The first clamp seat 2 and the second clamp seat 3 are respectively threadedly connected to the two ends of the outer side of the bidirectional screw rod 5, and one end of the bidirectional screw rod 5 is fixedly connected to the output shaft of the servo motor 4. By setting the displacement assembly, the servo motor 4 is used to drive the bidirectional screw rod 5 to rotate. Since the first clamp seat 2 and the second clamp seat 3 slide inside the connecting frame seat 1, they will not rotate. In this way, the first clamp seat 2 and the second clamp seat 3 will be displaced and approach each other, and at the same time, the first clamping roller 13 and the second clamping roller 15 are driven to move, thereby clamping and fixing the anti-bias wear coupling.

[0030] Reference Figure 1 and Figure 2 The first clamping roller 13 and the second clamping roller 15 are both covered with rubber sleeves. By arranging the rubber sleeves on the outside of the first clamping roller 13 and the second clamping roller 15, a buffering effect can be played when the anti-eccentric wear coupling is clamped and fixed, and the rubber surface has greater friction, thereby preventing slipping after clamping.

[0031] Working principle: When in use, the anti-eccentric wear collar is placed between the first clamping roller 13 and the second clamping roller 15, and then the servo motor 4 is used to drive the bidirectional screw 5 to rotate. Since the first clamping seat 2 and the second clamping seat 3 slide inside the connecting frame seat 1, they will not rotate, so that the first clamping seat 2 and the second clamping seat 3 will be displaced and approach each other, and at the same time drive the first clamping roller 13 and the second clamping roller 15 to move, so as to clamp and fix the anti-eccentric wear collar. Then the worm 18 can be rotated to drive the worm wheel 17 to rotate, and the worm wheel 17 and the second clamping roller 15 share the same rotating shaft, and at the same time drive the second clamping roller 15 to rotate, so that the position of the anti-eccentric wear collar can be fine-tuned.

[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
