[0019] This application provides a rope winch, which is mounted on the support of a drilling rig. Figure 1 This is a schematic diagram of the overall structure of a rope winch according to an embodiment of this application, as shown below. Figure 1 As shown, the rope winch includes: a support 100; a winding mechanism 200 connected to the support 100; the winding mechanism 200 is supported by the support 100 and driven by a power source (not shown) to rotate around a fixed point of the support 100; and a guide mechanism 300 connected to the support 100; the guide mechanism 300 is used to guide the rope so that the rope is wound around the winding mechanism 200.
[0020] In a specific example of this application, such as Figure 1 As shown, the bracket 100 includes: a bottom support assembly 101; a first side plate 102 and a second side plate 103 respectively connected to the bottom support assembly 101; the first side plate 102 and the second side plate 103 are spaced apart and together with the bottom support assembly 101 form a space for accommodating the winding mechanism 200.
[0021] In the above embodiments, such as Figure 1As shown, the bottom support assembly 101 includes: a base plate 1011 and a base plate 1012 spaced apart; the base plate 1011 and the base plate 1012 are respectively connected to the first side plate 102 and the second side plate 103; and stiffening plates 1013 and 1014 spaced apart; the stiffening plates 1013 and 1014 are respectively connected to the first side plate 102 and the second side plate 103; the base plate 1011 and the stiffening plate 1013 are matched at a preset angle; and the base plate 1012 and the stiffening plate 1014 are matched at a preset angle.
[0022] In the above embodiment, specifically, both the first side plate 102 and the second side plate 103 are pentagonal.

The stiffening plates 1013 and 1014 are connected to the waist edges of the first side plate 102 and the second side plate 103, respectively, with a preset included angle the same as the included angle between the bottom edge and the waist edge. Bolt holes are provided on the bottom plate 1011 and bottom plate 1012 for connection to the drilling rig's support.
[0023] In a specific example of this application, such as Figure 1 As shown, the winding mechanism 200 includes: a drum 201 connected to a power source, positioned in the space between the first side plate 102 and the second side plate 103, and rotatable around a fixed point on the first side plate 102 and the second side plate 103 to wind a rope; and circular plates 202 and 203 respectively disposed at both ends of the drum 201, with the circular plate 202 positioned closer to the first side plate 102 and the circular plate 203 positioned closer to the second side plate 103. The drum 201 between the circular plates 202 and 203 serves as the rope storage space, and the circular plates 202 and 203 prevent the rope from being thrown out of the winding mechanism 200, limiting the rope's storage range on the drum 201.
[0024] In the above embodiments, preferably, as follows: Figure 1 As shown, one end of the drum 201 near the first side plate 102 is connected to a power source. A keyway is provided between the drum 201 and the first side plate 102, and the power source is connected to the keyway. The other end of the drum 201 is connected to the second side plate 103 via a roller. The power source provides power to the drum 201, causing it to rotate. Those skilled in the art should understand that the power source can also be located on one side of the second side plate 103.
[0025] In other embodiments of this application, such as Figure 1 As shown, the bracket 100 also includes: reinforcing rod 104 and reinforcing rod 105, which are respectively connected to the first side plate 102 and the second side plate 103; the reinforcing rod 104 and reinforcing rod 105 are arranged parallel to the drum 202. The reinforcing rod 104 and reinforcing rod 105 serve to reinforce the bracket 100 as a whole.
[0026] In a specific example of this application, such as Figure 1 As shown, the guiding mechanism 300 includes: a guide shaft 301, which is arranged parallel to the drum 201; the two ends of the guide shaft 301 are respectively connected to the first side plate 102 through the first connecting plate 302 and to the second side plate 103 through the second connecting plate 303; a guide wheel 304, which is sleeved on the guide shaft 301 and can reciprocate along the axial direction of the guide shaft 301; the guide wheel 304 is provided with a groove 3041 along the circumferential direction to accommodate the rope.
[0027] In other embodiments of this application, such as Figure 1 As shown, the guide mechanism 300 further includes: a blocking ring 305 and a blocking ring 306, which are sleeved on the guide shaft 301; the distance between the blocking ring 305 and the blocking ring 306 is less than or equal to the distance between the circular plate 202 and the circular plate 203; the guide wheel 304 reciprocates along the axial direction of the guide shaft 301 within the space enclosed by the pair of blocking rings; wherein the blocking ring 305 is disposed near the first connecting plate 302, and the blocking ring 306 is disposed near the second connecting plate 303.
[0028] In the above embodiments, specifically, such as Figure 1 As shown, the blocking ring 305 is a cylinder fitted onto the guide shaft 301, and its length along the axial direction of the guide shaft 301 is greater than the gap between the first connecting plate 302 and the circular plate 202. The blocking ring 306 is a cylinder fitted onto the guide shaft 301, and its length along the axial direction of the guide shaft 301 is greater than the gap between the second connecting plate 303 and the circular plate 203. Since a flat key shaft is provided between the drum 201 and the first side plate 102, and a roller shaft is provided between the drum 201 and the second side plate 103, the lengths of the blocking rings 305 and 306 are not necessarily the same. Their lengths depend on the gap between the first connecting plate 302 and the circular plate 202 and the gap between the second connecting plate 303 and the circular plate 203.
[0029] In other embodiments of this application, such as Figure 1 As shown, the bracket 101 further includes: a first pad 106 disposed between the first connecting plate 302 and the first side plate 102; and a second pad 107 disposed between the second connecting plate 303 and the second side plate 103.
[0030] In other embodiments of this application, such as Figure 1 As shown, the guide mechanism 300 further includes a reinforcing plate 307 and a reinforcing plate 308, which are respectively disposed on the first connecting plate 302 and the second connecting plate 303. The reinforcing plates 307 and 308 serve to reinforce the guide mechanism 300.
[0031] In other embodiments of this application, such as Figure 1As shown, the guide mechanism 300 further includes: a pressure rod 309, which is arranged parallel to the guide shaft 301; the two ends of the pressure rod 309 are respectively connected to the first connecting plate 302 and the second connecting plate 303, and the gap between the pressure rod 309 and the guide wheel 304 is smaller than the diameter of the rope. By setting the pressure rod 309, the rope is firmly confined within the groove 3041 of the guide wheel 304, preventing the rope from swinging out and getting knotted.
[0032] The working principle of this utility model is as follows: The rope is wound around the drum 201 of the winding mechanism 200, and one end passes through the groove 3041 of the guide wheel 304 and connects to the retrieval tool. When core retrieval is required, the retrieval tool moves down along the drill rod, and the rope disengages from the drum 201. When it reaches the preset position, core retrieval begins. After core retrieval is completed, the power source starts to drive the drum 201 to rotate and wind the rope. During winding, the rope is evenly wound along the axis of the drum 201 by the reciprocating motion of the guide wheel 304. Under the constraint of the circular plates 202 and 203, the rope is prevented from being thrown out of the winding mechanism 200. With the cooperation of the groove 3041 of the guide wheel 304 and the pressure rod 309, the rope is prevented from tangling or being wound at a fixed end, effectively reducing rope wear and manual operation, and improving operating efficiency.
