[0038] The application provides a winch, which comprises a winch frame, a rotating drum and a guide mechanism. Figures 1 to 11 As shown, the winch comprises a winch frame, a rotating drum 130 and a guide mechanism; the winch frame comprises two opposite standing support plates 110, the rotating drum 130 is rotatably arranged between the two support plates 110, and the guide mechanism is fixedly arranged between the two support plates 110, and the rotating drum 130 is arranged adjacent to the guide mechanism; the guide mechanism comprises two fixed clamping plates 200, two support wheel 310 assemblies 300 and a counting wheel 510 assembly 500; the two fixed clamping plates 200 are fixedly arranged between the two support plates 110, and the two fixed clamping plates 200 are oppositely arranged, the two support wheel 310 assemblies 300 and the counting wheel 510 assembly 500 are arranged between the two fixed clamping plates 200, and the counting wheel 510 assembly 500 is located between the two support wheel 310 assemblies 300; the cable on the rotating drum 130 is adapted to pass through one of the two support wheel 310 assemblies 300, the counting wheel 510 assembly 500 and the other support wheel 310 assembly 300 in sequence; each of the two support wheel 310 assemblies 300 comprises a support wheel 310 and a first rotating shaft 320; the two ends of the first rotating shaft 320 are respectively arranged through the two fixed clamping plates 200, the support wheel 310 is sleeved on the first rotating shaft 320 and is rotatably connected with the first rotating shaft 320; the two ends of the first rotating shaft 320 in one of the two support wheel 310 assemblies 300 are both provided with a joint bearing 330, and the first rotating shaft 320 is fixedly connected with the fixed clamping plate 200 through the joint bearing 330.

[0039] It should be noted that the winch frame is suitable for providing a stable mounting base for the rotating drum 130 and the cable guide mechanism. The rotating drum 130 is rotatably arranged between the two support plates 110 and is driven to rotate by a motor or other power source, thereby realizing the winding and unwinding of the cable on the rotating drum 130. The cable guide mechanism is fixedly arranged between the two support plates 110 and adjacent to the rotating drum 130. The cable guide mechanism is suitable for guiding the cable. During the winding and unwinding of the cable, the cable guide mechanism can accurately guide the cable to enter or exit the rotating drum 130 along a predetermined path, avoiding friction, collision or entanglement between the cable and other parts of the winch. The two fixed clamping plates 200 provide a mounting base for the two support wheel 310 assemblies 300 and the counting wheel 510 assembly 500 and the like. The fixed clamping plates 200 are suitable for mounting the cable guide mechanism on the winch. The two fixed clamping plates 200 arranged opposite to each other can ensure that the cable guide mechanism is stably fixed on the winch, avoiding loosening or displacement of the support wheel 310 assembly 300 and the counting wheel 510 assembly 500 during operation. The cable on the rotating drum 130 passes through one of the support wheel 310 assemblies 300, the counting wheel 510 assembly 500 and the other support wheel 310 assembly 300 in sequence. The counting wheel 510 assembly 500 is suitable for coaxial connection with the optical encoder 540 and counts the cable passing through the counting wheel 510 by synchronous rotation. The support wheel 310 assembly 300 is suitable for guiding the cable to run along a predetermined path, ensuring that the cable does not directly rub or collide with other parts of the winch during feeding and recycling, thereby protecting the integrity of the cable.

[0040] The support wheel 310 is suitable for guiding the cable to move along a predetermined direction and trajectory during winding and unwinding, ensuring that the cable can accurately enter or exit the rotating drum 130. The first rotating shaft 320 fixedly arranges the support wheel 310 between the two fixed clamping plates 200. The fixed clamping plate 200 is provided with a first slot hole 210. The first rotating shaft 320 is fixedly installed in the first slot hole 210 of the fixed clamping plate 200 and located between the two fixed clamping plates 200. The support wheel 310 is sleeved on the first rotating shaft 320, thereby realizing the relative rotation connection between the support wheel 310 and the first rotating shaft 320.

[0041] The overall structure of the present application is compact. By installing the support wheel 310 and the counting wheel 510 in the cable guide mechanism on one winch frame, an integrated design is realized, greatly saving the installation space, reducing the requirements for the site, making the winch of the present application adaptable to more use scenarios. The integrated structure of the winch facilitates transportation and installation, reduces transportation costs. At the same time, the cable guide mechanism is directly installed on the winch, simplifying the connection between components, improving the efficiency and stability of the cooperation between the rotating drum 130 and the cable guide mechanism, and reducing the probability of failure.

[0042] As Figures 2 to 5As shown, the spherical bearing 330 is mounted on the fixed clamping plate 200 and is connected to the first rotating shaft 320. The spherical bearing 330 is suitable for adjusting the deflection angle of the first rotating shaft 320 in its horizontal plane, thereby adjusting the deflection angle of the support wheel 310 on the first rotating shaft 320. Compared with the prior art, when the cable is lowered, the spherical bearing 330 and the first rotating shaft 320 cooperate with each other to flexibly adjust the deflection angle of the support wheel 310 according to the actual operation requirements, ensuring that the cable and the support wheel 310 always maintain uniform and stable line contact, reducing cable wear and damage, extending the service life of the cable, and expanding the working range and applicable scenarios of the winch.

[0043] The deflection angle refers to the left and right deflection of the plane where the support wheel 310 is located relative to the plane where the wellhead is located. The value of the deflection angle is 5°.

[0044] Furthermore, such as Figure 1 As shown, the spherical bearing 330 is mounted on the support wheel 310 assembly 300 on the side of the counting wheel 510 assembly 500 away from the rotating drum 130.

[0045] Preferably, the spherical plain bearing 330 adopts the GE17C spherical plain bearing in the prior art.

[0046] In one possible implementation, such as Figure 1 As shown, the main body of the rotating drum 130 is cylindrical. The outer wall of the rotating drum 130 is suitable for winding cables.

The two winch shafts 120 are placed in the slots of the two support plates 110, and the two winch shafts 120 are rotatably connected to the support plates 110. The rotating drum 130 rotates to realize the lowering and winding of the cable.

[0047] In one possible implementation, such as Figures 2 to 5 As shown, the spherical bearing 330 includes an outer ring 332 and an inner ring 331; the inner sidewall of the outer ring 332 is provided with an inner spherical surface, the outer sidewall of the inner ring 331 is provided with an outer spherical surface that matches the inner spherical surface, the inner ring 331 is movably disposed inside the outer ring 332, and a mounting hole is provided on the inner ring 331, one end of the first rotating shaft 320 is fixedly installed in the mounting hole.

[0049] In a possible implementation, a preset distance is provided between the inner spherical surface and the outer spherical surface. It should be noted that the preset distance between the inner spherical surface and the outer spherical surface allows the inner ring 331 to have a certain activity space in the outer ring 332, which makes the inner ring 331 more flexible during operation, reduces the friction and wear of the inner ring 331 during operation, and prolongs the service life of the joint bearing 330.

[0050] In a possible implementation, the preset distance is 1 mm.

[0051] In a possible implementation, as shown in Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 It further includes two fixed covers 230; the two fixed covers 230 are arranged on the fixed clamping plate 200 and are respectively located on the two sides of the joint bearing 330, and are suitable for fixing the joint bearing 330 on the fixed clamping plate 200.

[0052] It should be noted that, as shown in Figure 8 、 Figure 9As shown, the main body of the fixed cover 230 is in a circular plate structure, and a fixed shaft hole 231 is formed in the fixed cover 230, which is matched with the outer contour of the first rotating shaft 320.

The fixed cover 230 is fixedly installed on both sides of the fixed clamping plate 200, and the two fixed covers 230 are matched with the fixed clamping plate 200 to fix the outer ring 332 in the first slot hole 210. By arranging the fixed cover 230, the displacement of the joint bearing 330 during work is avoided, and the stability of the structure of the joint bearing 330 is ensured.

[0053] In a possible implementation, the deep groove ball bearing 400 is arranged on the first rotating shaft 320 in the support wheel 310 assembly 300.
