In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0034] Figure 1 The front view of the winch with the counting wheel pendulum structure according to the embodiment of the present application is shown; Figure 1As shown, the winch with a counting wheel pendulum structure includes: a winch, a counting wheel pendulum structure; the winch includes two brackets 900 and a drum 800, and the two ends of the drum 800 can be rotatably set on the bracket 900; the drum 800 is suitable for winding a cable 840; the counting wheel pendulum structure includes: a base 100, a rotating seat, a swing arm 300 and a counting wheel 400; the base 100 is provided with a first connecting column 120 and a second connecting column 130, the first connecting column 120 and the second connecting column 130 both pass through the opposite sides of the base 100 and the body length direction of the first connecting column 120 and the body length direction of the second connecting column 130 are parallel to each other; the base 100 can slide along the body length direction of the first connecting column 120 and the second connecting column 130, and the first connecting column 120 and the second connecting column 130 are parallel to each other. Both ends of the connecting column 120 and the second connecting column 130 are fixedly connected to the bracket 900; the rotating seat can be rotatably set on the base 100 through the first rotating shaft 110, and one end of the swing arm 300 is rotatably connected to the rotating seat; the other end of the swing arm 300 is provided with a first pressure wheel 600 and a second pressure wheel 700 arranged in a stacked manner; the swing arm 300 is provided with a counting wheel 400, and the counting wheel 400 is located between the rotating seat and the first pressure wheel 600; the end of the swing arm 300 connected to the rotating seat is provided with a rear support wheel 500, and the rear support wheel 500 and the counting wheel 400 are both located on the same side of the swing arm 300; the winch cable 840 is suitable for passing through the rear support wheel 500, the counting wheel 400 and passing through between the first pressure wheel 600 and the second pressure wheel 700 in sequence.

[0035] Here, it should be noted that the base 100 provides an installation foundation for the rotating seat, swing arm 300 and other equipment. Figure 1 As shown, the base 100 is mounted on the bracket 900 of the winch so that the cable 840 on the winch can pass through the counting wheel 400 during the recovery and lowering process. The position of the base 100 on the bracket 900 can be adjusted according to the position of the cable end so that the base 100 is close to the cable end. The rotating base rotates in the horizontal plane, which can drive the swing arm 300 to rotate in the horizontal plane with the rotating base as the center (such as Figure 10 As shown), it is easy to adjust the rolling direction of the counting wheel 400; the swing arm 300 is rotatably connected to the rotating seat, and the swing arm 300 can be rotated in the coronal plane with the rotating seat as the center (as shown Figure 9) to achieve the folding of the swing arm 300. The counting wheel 400 on the swing arm 300 is adapted to be coaxially connected to the photoelectric code disk 410. The photoelectric code disk 410 counts the cables passing through the counting wheel 400 by synchronous rotation. The first pressure wheel 600 and the second pressure wheel 700 are adapted to jointly clamp the cable 840 and guide it for transmission. They also provide a certain amount of pressure when the cable 840 passes over the counting wheel 400, effectively connecting the cable 840 and the counting wheel 400, thereby ensuring the accuracy of the counting by the counting wheel 400 and improving the smoothness of the cable 840 during the winding and lowering processes. The overall structure of the present application is compact. The counting wheel 400 is directly mounted on the winch through the counting wheel swing structure. It is integrated with the winch and does not need to be transported and stored separately during use or in an idle state. When the winch is working, the swing arm 300 is rotated and rotated to a horizontal plane so that the counting wheel 400 extends out of the winch. When the winch does not need to work or needs to be transported and shifted, the swing arm 300 is rotated to fold upward to form a Figure 9 The counting wheel 400 can be folded into the winch in a state of being folded into the winch, which can reduce the overall equipment footprint, save the internal space of the logging vehicle, facilitate transportation and avoid damage to the swing arm 300. At the same time, the counting wheel 400 of the present application can be freely swung in multiple directions, which can be applied to various logging environments and can meet all usage requirements regardless of the distance from the wellhead.

[0036] In one possible implementation, Figure 4 As shown, the base 100 has a rotation hole, into which a first rotating shaft 110 is inserted and rotatably connected to the base 100. The top end of the first rotating shaft 110 is fixedly connected to the bottom of the rotating base. It should be noted that the rotating hole is suitable for receiving the first rotating shaft 110, which rotates within the base 100 to enable the rotating base to rotate.

[0037] In a possible implementation, the first rotating shaft 110 is disposed in the rotating hole via two first bearings 111. Figure 4 As shown, the inner rings of the two first bearings 111 are sleeved on the outside of the first rotating shaft 110, and the outer rings of the two first bearings 111 contact the inner wall of the first shaft hole. Under the action of the two first bearings 111, the first rotating shaft 110 can rotate in the rotating hole.

[0038] In one possible implementation, as 2 and Figure 3As shown, the base 100 has a block-shaped structure and is provided with a first connecting post 120 and a second connecting post 130. The first connecting post 120 and the second connecting post 130 both extend through opposite sides of the base 100, and the lengths of the first connecting post 120 and the second connecting post 130 are parallel to each other. It should be noted that the first connecting post 120 and the second connecting post 130 are suitable for mounting the base 100 on the winch bracket 900. The base 100 has two through-holes, through which the first connecting post 120 and the second connecting post 130 respectively pass to connect to the base 100.

[0039] In one possible implementation, Figure 5 As shown, the rotating seat includes: a connecting plate 200, a support member 220 and a second rotating shaft 210; the support member 220 is suitable for installing the second rotating shaft 210, and the second rotating shaft 210 is suitable for connecting the swing arm 300; the connecting plate 200 is arranged on the top surface of the base 100; the second rotating shaft 210 passes through the support member 220 and is rotatably connected to the support member 220 through a bearing, and one end of the swing arm 300 is sleeved on the second rotating shaft 210 and fixedly connected to the second rotating shaft 210. With this arrangement, when the second rotating shaft 210 rotates, the swing arm 300 can be driven to rotate; as shown Figure 7 As shown, a circular hole 340 is provided at one end of the swing arm 300 for the second rotating shaft 210 to pass through.

[0040] like Figure 5 As shown, the connecting plate 200 is provided with a rotating shaft hole 230, which is opposite to the rotating hole of the base 100. The first rotating shaft 110 is inserted into the rotating shaft hole 230 and the rotating hole of the base 100, and the first rotating shaft 110 is fixedly connected to the connecting plate 200, so that when the connecting plate 200 is rotated, the first rotating shaft 110 can rotate in the rotating hole.

[0041] like Figure 5 As shown, the main body of the support member 220 is a triangular plate-like structure with two screw holes 221 on one side of its bottom edge. The connecting plate 200 also has corresponding screw holes. The support member 220 and the connecting plate 200 are connected and fixed by bolts 222. A through hole is formed at the top of the support member 220, and the second rotating shaft 210 extends through the through hole. Furthermore, the second rotating shaft 210 is an eccentric shaft.

[0042] In a possible implementation, a hand wheel 211 is provided at one end of the second rotating shaft 210. The second rotating shaft 210 can be rotated by rotating the hand wheel 211.

[0043] In one possible implementation, Figure 3As shown, the rear support wheel 500 is rotatably connected to the second rotating shaft 210 via a third bearing (not shown). The rear support wheel 500 is sleeved on the outer ring of the third bearing, and the inner ring of the third bearing is sleeved on the second rotating shaft 210, thereby achieving the rotational connection of the rear support wheel 500 relative to the second rotating shaft 210. It should be noted that the rear support wheel 500 serves as a transition device, which is conducive to the stability of the cable 840 during movement and prevents the cable 840 from shifting when moving.

[0044] In a possible implementation, one end of the swing arm 300 connected to the second rotating shaft 210 is provided with a protruding abutment portion 360, which is adapted to keep the swing arm 300 in a horizontal state when the abutment portion 360 contacts the connecting plate 200. Figure 7 As shown, an abutment portion 360 is protruding from one side of the swing arm 300. When the swing arm 300 rotates in the coronal plane until it reaches a horizontal position, the abutment portion 360 of the swing arm 300 contacts the top surface of the rotating seat, thereby achieving the maximum rotation angle, preventing the swing arm 300 from rotating excessively, and keeping the swing arm 300 in a horizontal state, making it easier for the winch cable 840 to pass through the counting wheel 400.

[0045] In one possible implementation, Figure 5 As shown, the support member 220 is provided with a limiting member 321, as shown in FIG. Figure 7 As shown, the swing arm 300 is provided with an arc-shaped limiting hole 320; the limiting member 321 penetrates into the limiting hole 320. When the swing arm 300 is folded and rotated, the limiting member 321 does not move, and the limiting hole 320 rotates, which limits the folding of the swing arm 300 and prevents the swing arm 300 from folding excessively.

[0046] In one possible implementation, Figure 7 As shown, a circular first connecting hole 330 is opened in the middle of the swing arm 300. Figure 6 As shown, a central shaft 430 is fixed in the middle of the counting wheel 400, and the central shaft 430 of the counting wheel 400 is arranged in the first connecting hole 330 through the second bearing 420. Figure 2 and Figure 6 As shown, the central axis 430 of the counting wheel 400 passes through the first connecting hole 330, the inner ring of the second bearing 420 is sleeved on the central axis 430 of the counting wheel 400, and the outer ring of the second bearing 420 is fixedly connected to the bearing seat 431. The bearing seat 431 is fixedly connected to the swing arm 300, thereby enabling the central axis 430 of the counting wheel 400 to be rotatably mounted on the swing arm 300. Furthermore, the bearing seat 431 has two or more bolt holes, and the swing arm 300 has two or more bolt holes 310. The bearing seat 431 and the swing arm 300 can be fixedly connected by bolts.

[0047] Further, such as Figure 2As shown, the counting wheel 400 is provided with a photoelectric code disk 410. The central axis 430 of the counting wheel 400 is coaxially connected to the photoelectric code disk 410, and counts in a synchronous rotation manner. In one possible implementation, for each rotation of the counting wheel 400, the cable 840 moves 0.25m, and the photoelectric code disk 410 generates 250 pulse signals, that is, for each meter the cable 840 moves, the photoelectric code disk 410 generates 1000 pulses, and the counting wheel 400 rotates four times. The photoelectric code disk 410 transmits the pulse signal to the winch controller to obtain the moving distance of the cable 840, that is, the drilling depth.

[0048] In one possible implementation, Figure 6 As shown, the first pressure wheel 600 is provided with a pressure wheel shaft 610, and the first pressure wheel 600 is rotatably connected to the pressure wheel shaft 610 through a fourth bearing (not shown in the figure). The first pressure wheel 600 is sleeved on the outer ring of the fourth bearing, and the inner ring of the fourth bearing is sleeved on the pressure wheel shaft 610, thereby realizing the rotation of the first pressure wheel relative to the pressure wheel shaft 610. One end of the pressure wheel shaft 610 passes through the second connecting hole 350 of the swing arm 300 and is fixedly connected to the swing arm 300.

[0049] like Figure 6 As shown, the structure of the second pressure wheel 700 is the same as that of the first pressure wheel 600. The second pressure wheel 700 is rotatably connected to the pressure wheel shaft 710 through the fifth bearing (not shown in the figure). The second pressure wheel 700 is sleeved on the outer ring of the fifth bearing, and the inner ring of the fifth bearing is sleeved on the pressure wheel shaft 710, thereby realizing the rotation of the second pressure wheel 700 relative to the pressure wheel shaft 710. One end of the pressure wheel shaft 710 passes through another second connecting hole 350 of the swing arm 300 and is fixedly connected to the swing arm 300.

[0050] In one possible implementation, Figure 7 As shown, two second connecting holes 350 are provided at one end of the swing arm 300 away from the rotating seat, and the pressure wheel shaft 610 of the first pressure wheel 600 passes through one second connecting hole 350, and the pressure wheel shaft 610 is locked and fixed by a nut 611; the pressure wheel shaft 710 of the second pressure wheel 700 passes through another second connecting hole 350, and the pressure wheel shaft 710 is locked and fixed by a nut 711; it should be noted that the second connecting hole 350 through which the pressure wheel shaft 610 of the first pressure wheel 600 passes is a circular hole; the second connecting hole 350 through which the pressure wheel shaft 710 of the second pressure wheel 700 passes is an oblong hole. The design of the oblong hole can adjust the distance between the first pressure wheel 600 and the second pressure wheel 700, so as to adapt to cables 840 of different diameters.

[0051] In one possible implementation, Figure 1 and Figure 10As shown, the winch frame 900 includes two relatively upright support plates 910, and the first connecting column 120 and the second connecting column 130 of the counting wheel pendulum structure are fixedly arranged between the two support plates 910; the rotating drum 800 can be rotatably arranged between the two support plates 910, and the rotating drum 800 is arranged adjacent to the counting wheel pendulum structure.

[0052] In one possible implementation, Figure 1 As shown, the main body of the drum 800 is a cylindrical structure, and a connecting plate 830 is fixedly provided at both ends of the drum 800. Figure 10 As shown, a winch shaft 820 is fixed on the side of the two connecting plates 830 facing away from the drum 800, and the winch shaft 820 is coaxially arranged with the drum 800. The two winch shafts 820 are placed in the slots of the two support plates 910, and the two winch shafts 820 are rotatably connected to the support plates 910. Figure 10 As shown, the sixth bearing 810 is also included, which is disposed in the slotted hole. The inner ring of the sixth bearing 810 is sleeved on the winch shaft 820. The two winch shafts 820 and the support plate 910 are rotatably connected via the sixth bearing 810. The outer ring of the sixth bearing 810 is provided with a bearing seat 811. The bearing seat 811 and the support plate 910 are fixedly connected by bolts, thereby improving the installation stability of the sixth bearing 810. The winch shaft 820 on one side can be connected to the output end of the motor. The motor directly drives the winch shaft 820 to rotate, and the winch shaft 820 drives the rotating drum 800 to rotate, thereby realizing the retraction and extension of the cable 840 by the rotating drum 800.

[0053] In one possible implementation, Figure 9 and Figure 10 As shown, a sprocket 860 is fixedly provided on the connecting plate 830 on one side of the rotating drum 800. The sprocket 860 is located on the side of the connecting plate 830 facing away from the rotating drum 800 and is coaxially arranged with the rotating drum 800. It should be noted that the sprocket 860 can also be driven to rotate by chain transmission, and the sprocket 860 drives the connecting plate 830 and the rotating drum 800 to rotate.

[0054] The two ends of the first connecting column 120 and the second connecting column 130 are fixedly connected to the two support plates 910, thereby fixing the base 100 on the winch frame 900. Figure 1 As shown, both ends of the first connecting column 120 and the second connecting column 130 pass through the two supporting plates 910 and are thus mounted on the two supporting plates 910 .

[0055] When the winch is ready to work, rotate the swing arm 300 and rotate it to a horizontal plane so that the counting wheel 400 extends out of the winch. Adjust the position of the base 100 on the first connecting column 120 and the second connecting column 130 according to the position of the cable end, so that the base 100 is close to the cable end and the distance between the base and the cable end is reduced. Rotate the rotating seat so that the angle between the length direction of the swing arm 300 and the length direction of the rotating drum 800 is the same as the initial lowering angle of the cable 840, so that the cable 840 passes the counting wheel 400 smoothly; then the winch starts working and the cable 840 is lowered. During the lowering process of the cable 840, if Figure 10 As shown, the cable lowering angle a (the angle between the length direction of the drum 800 and the moving direction of the cable 840) will change with the winding position of the cable on the drum. At this time, the rotating seat can be rotated to make the length direction of the swing arm 300 always parallel to the moving direction of the cable 840, and the counting wheel 400 and the moving direction of the cable 840 are on the same straight line. In this way, the cable 840 can effectively pass through the counting wheel 400, and ensure the accuracy of the counting by the counting wheel 400, while avoiding the counting wheel 400 from hindering the lowering process of the cable 840.

[0056] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
