[0052] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0053] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0054] It should be noted that in the description of the embodiments of the present application, terms such as "upper", "lower", "inside", and "outside" indicating orientation or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description, and do not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0055] In addition, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0056] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0057] During construction machinery operations, a winch is sometimes required to reel in or release the wire rope. This involves winding the wire rope around the winch's drum, which rotates to wind or release the rope. A rope clamp is used to press the drum to ensure the wire rope remains properly tensioned during the hoisting process.

[0058] In the prior art, the rope press is axially mounted on the rotating platform of the winch via a fixed shaft seat so as to be crimped with the wire rope on the drum, that is, the fixed shaft seat is welded to the vertical plate of the rotating platform, the rope press is connected to the fixed shaft seat, and one end of the rope press is crimped with the drum. However, the axial length of the fixed shaft seat is a fixed value, and it can only adapt to rope presses of a single size (such as a single gear pitch), which has low versatility. In some cases (such as when the rope press is aging or the wire rope requires a larger or smaller crimping force), it is necessary to replace rope presses of different sizes. The axial length of the fixed shaft seat is a fixed value, which fixes the installation distance of the rope press and can only adapt to rope presses of a single size (such as a single gear pitch). It has low versatility and is difficult to replace. Moreover, as the compressor is used for a long time, the vertical plate of the rotating platform is subjected to uneven force and is prone to tilting or bending, resulting in a change in the gear pitch between the two vertical plates. It is necessary to grind the end face of the fixed shaft seat to change the axial length of the fixed shaft seat to adapt to the length of the rope press, which is a relatively cumbersome and complicated operation.

[0059] In view of this, the present application provides a rope press shaft seat and a rotary drilling rig, which are provided with at least one adjustable shaft seat, and the adjustable shaft seat includes: a shaft seat for detachably connecting with one end of the rope press; a movable component connected with the shaft seat to drive the shaft seat to move along the axial direction of the shaft seat; a fixed disk arranged around the circumference of the movable component, and the fixed disk is used to connect with the vertical plate of the rotary platform; a fixed component, and the fixed component is used to be plugged into the shaft seat, and the fixed component is plugged into the shaft seat through the hole of the rope press to connect the shaft seat to the rope press. By driving the shaft seat to move along the axial direction of the shaft seat through the movable component, the axial length of the shaft seat can be adjusted according to rope presses of different sizes, thereby facilitating adaptation to rope presses of different sizes and improving the versatility of the shaft seat.

[0061] On the one hand, the present application provides a rope press shaft seat, comprising: at least one adjustable shaft seat, the adjustable shaft seat comprising: a connecting seat 100, for being detachably connected to one end of the rope press 10; a movable component 200, connected to the connecting seat 100, to drive the connecting seat 100 to move along the axial direction of the connecting seat 100; a first fixing member 300, the first fixing member 300 is arranged around the circumference of the movable component 200, for connecting to the machine body; a fixing component 400, the fixing component 400 is used to be plugged into the connecting seat 100 through the hole of the rope press 10, so that the connecting seat 100 is connected to the rope press 10.

[0062] The machine body includes a rotating platform 40, two vertical plates 30, and a hoisting drum 20. The two vertical plates 30 are arranged relative to each other on the rotating platform 40. The hoisting drum 20 is arranged on the rotating platform 40 and located between the two vertical plates 30. The rope pressure device 10 includes a frame, a tension spring 12, a pressure roller 13, and a connecting shaft 14. The frame body is provided with a frame shaft sleeve 11, which is used to connect to the connecting seat 100. The pressure roller 13 and the connecting shaft 14 are arranged on the frame body at intervals. One end of the tension spring 12 is connected to the rotating platform and the other end is connected to the frame body. The pressure roller 13 is used to press the wire rope of the hoisting drum 20 to adjust the tension of the wire rope. The connecting shaft 14 is arranged on the side of the frame body away from the hoisting drum 20 to enhance the support strength of the frame body.

[0063] The connecting base 100 is cylindrical and has a mounting cavity therein for connection to the rope press 10. A locking hole 600 is provided on the side of the connecting base 100. A chamfer 111 is provided on the end of the connecting base 100 facing the rope press 10. The present application does not limit the angle of the chamfer 111; for example, the chamfer 111 is 30 degrees or 45 degrees. Of course, the chamfer 111 can also be a circular chamfer.

[0064] The end of the connecting seat 100 away from the rope press 10 is provided with a connecting portion for connecting with the movable assembly. The present application does not limit the structure of the connecting portion. For example, the connecting portion can be a limiting step 110 or a rotating thread.

[0065] The movable assembly 200 is connected to the connecting seat 100 to drive the connecting seat 100 to move along the axial direction of the connecting seat 100. The movable assembly 200 facilitates adjustment of the axial length of the connecting seat 100. The present application does not limit the number of connecting seats 100. For example, the number of connecting seats 100 is two, each connecting seat 100 is connected to the two ends of the rope press 10 respectively, the distance between the two connecting seats 100 is the stop distance, and the rope press 10 is set corresponding to the stop distance.

[0066] The first fixing member 300 is disposed around the movable assembly 200 and is used to connect to the vertical plate 30 of the rotary platform 40. For example, the end surface of the first fixing member 300 is welded to the vertical plate 30. Furthermore, fixing holes 310 are provided around the first fixing member 300, through which screws are threadedly connected to the vertical plate 30.

[0067] The fixing assembly 400 is used to fix the rope press 10 to the connecting seat 100. Specifically, the fixing assembly 400 is plugged into the connecting seat 100, and the fixing assembly 400 is plugged into the connecting seat 100 through the hole of the rope press 10, so that the connecting seat 100 is connected to the rope press 10. The hole of the rope press 10 is the frame sleeve 11. The fixing assembly 400 includes a sleeve 410 and a fixing part 420, one end of the sleeve 410 is plugged into the connecting seat 100, and the other end of the sleeve 410 is connected to the frame sleeve 11, and the fixing part 420 is plugged into the connecting seat 100 in turn through the sleeve 410 and the frame sleeve 11 of the rope press 10. This application does not limit the structure of the fixing part 420, and the fixing part 420 is a pin or a pin shaft.

[0068] The rope press shaft seat in the embodiment of the present application drives the connecting seat 100 to move along the axial direction of the connecting seat 100 through the movable component 200. The axial length of the connecting seat 100 can be adjusted according to rope presses of different sizes, thereby facilitating adaptation to rope presses of different sizes and improving the versatility of the connecting seat 100.

[0069] In one possible implementation, in the rope press shaft seat in the embodiment of the present application, a limiting step 110 is provided in the connecting seat 100, and the movable component 200 includes a piston rod 210, which is connected to the limiting step 110, and the piston rod 210 is used to drive the connecting seat 100 to move along the axial direction of the connecting seat 100.

[0070] The limiting step 110 is provided at the end of the connecting base 100 away from the rope press 10. The limiting step 110 may include multiple steps or only one step, and the embodiment of the present application is not limited to this, so as to adapt to piston rods 210 of different diameters. The rope press shaft seat in the embodiment of the present application facilitates the adjustment of the axial position of the connecting base 100 by extending or contracting the piston rod 210 to adapt to rope presses 10 of different sizes.

[0071] In one possible implementation, the rope press shaft seat in the embodiment of the present application, the movable component 200 also includes a driving member 220, which is connected to the piston rod 210, and the driving member 220 is used to drive the piston rod 210 to move along the axial direction of the connecting seat 100.

[0072] The present embodiment does not limit the structure of the driver 220. The driver 220 is connected to the piston rod 210 and is used to drive the piston rod 210 to extend or retract, thereby moving the connecting base 100 in its axial direction. The driver 220 may be a hydraulic cylinder. The driver 220 controls the extension or retraction of the piston rod 210, facilitating precise adjustment of the position of the connecting base 100. Hydraulic cylinders can provide significant thrust and pull, making them suitable for heavy-duty applications.

[0073] In one possible implementation, the rope press shaft seat in the embodiment of the present application, the movable component 200 also includes a retaining member 230, the retaining member 230 is connected to the piston rod 210, and the retaining member 230 is electrically connected to the driving member 220 to keep the piston rod 210 in the current position.

[0074] It should be noted that the retaining member 230 is a retaining valve, which facilitates the position of the connecting seat 100 to remain unchanged after being adjusted to the target position or the preset position, thereby preventing the displacement of the piston rod 210 due to vibration.

[0075] For example, when the piston rod moves to a predetermined position, the valve core of the retaining valve moves to the closed position of the valve body, thereby closing the fluid passage. Fluid flow is prevented, and the pressure on the piston rod decreases to a state balanced with the spring force. Without external force, the piston rod remains in its current position, achieving a fixed position.

[0076] The control unit also includes a control unit that pre-stores the corresponding opening dimensions for different rope press models 10, thereby reducing errors and time required for manual adjustment. The opening dimension represents the installation distance compatible with the rope press 10. The control unit also includes a display screen. During operation, the rope press model is selected on the screen, and the hydraulic cylinder position of the connecting base 100 is automatically adjusted according to pre-set parameters to accommodate the opening dimensions of different rope press models.

[0077] In one possible implementation, in the rope press shaft seat in the embodiment of the present application, the first fixing member 300 is a fixed disk, which is mounted on the movable component 200. The fixed disk has a plurality of fixing holes 310, and each fixing hole 310 is arranged at intervals along the circumference of the fixed disk.

[0078] Specifically, the embodiment of the present application does not limit the shape of the fixing hole 310, and the fixing hole 310 can be a circular hole or a square hole. A screw passes through the fixing hole 310 and is threadedly connected to the vertical plate 30. The fixing hole 310 facilitates the fastening of the first fixing member 300 to the vertical plate 30, facilitating a detachable connection between the first fixing member 300 and the vertical plate 30, thereby providing fixed support for the movable assembly 200.

[0079] In one possible implementation, the rope press shaft seat in the embodiment of the present application, the fixing assembly 400 includes a sleeve 410 and a fixing member 420, the sleeve 410 is used to be plugged into the connecting seat 100, and the fixing member 420 is plugged into the connecting seat 100 through the holes of the sleeve 410 and the rope press 10 in turn.

[0080] The sleeve 410 includes a main body and an end portion. The diameter of the end portion is larger than the diameter of the main body. The end portion has a first end face and a second end face. The first end face and the second end face are arranged opposite to each other, the first end face is arranged toward the connecting seat 100, and the second end face is arranged away from the connecting seat 100. The main body is plugged into the connecting seat 100, the first end face abuts against the connecting seat 100, and the second end face abuts against the frame sleeve 11 of the rope presser 10. The axes of the fixing member 420, the sleeve 410, and the frame sleeve 11 are all on the same straight line. The fixing member 420 is a locking pin. The sleeve 410 and the fixing member 420 enable the connecting seat 100 to be quickly locked or unlocked, thereby simplifying the installation steps of the connecting seat 100 and the rope presser 10.

[0081] When installing the rope presser 10, insert the sleeve 410 axially into the connecting seat 100 at one end, and fit the first end face with the end face of the sleeve; secondly, place the rope presser 10 directly in front of the winch drum 20, and fit the frame sleeve 11 in the rope presser 10 with the second end face, and align them axially; finally, coaxially connect the fixing piece 420 with the connecting seat 100, and fit it with the other side of the frame sleeve 11, and finally lock it in place.

[0082] When there are two connecting sockets 100 , the above operation is repeated for the two connecting sockets 100 .

[0083] In one possible implementation, the rope press shaft seat in the embodiment of the present application also includes a locking piece 500, and both the connecting seat 100 and the shaft sleeve 410 have locking holes 600. The axes of the two locking holes 600 are perpendicular to each other, and the locking piece 500 passes through each locking hole 600 in turn to be plugged into the connecting seat 100 and the shaft sleeve 410 in turn.

[0084] In order to ensure that the rope press 10 is firmly fixed to the connecting seat 100, a locking piece 500 is also provided. Both the connecting seat 100 and the shaft sleeve 410 have locking holes 600. The axes of the two locking holes 600 are perpendicular to each other. The locking piece 500 passes through each locking hole 600 in turn to be plugged into the connecting seat 100 and the shaft sleeve 410 in turn, thereby further enhancing the connection strength between the connecting seat 100 and the shaft sleeve 410.

[0085] In one possible implementation, the rope press shaft seat in the embodiment of the present application has a chamfer 111 on the end of the connecting seat 100 facing the rope press 10. The angle of the chamfer 111 ranges from 30 degrees to 65 degrees. The present application does not limit the inclination angle of the chamfer 111. For example, the chamfer 111 is 30 degrees, 45 degrees, or 65 degrees. Of course, the chamfer 111 can also be a circular chamfer.

[0086] It is understood that the chamfer 111 can increase the contact area between the connecting base 100 and the rope press 10, thereby dispersing the pressure, reducing the wear of a single contact point, and improving the wear resistance of the connecting base 100. In addition, the chamfer 111 has a certain guiding and positioning function, making it easier for the rope press 10 to be inserted into or removed from the connecting base 100.

[0087] In one possible implementation, the rope presser shaft seat in the embodiment of the present application includes at least two adjustable shaft seats, each of which is configured to be positioned at opposite ends of the rope presser 10. For example, there are two adjustable shaft seats, i.e., there are also two connecting seats 100, with the two connecting seats 100 being connected to the two vertical plates 30 in a one-to-one correspondence. The rope presser 10 is positioned between the two vertical plates 30, with the two connecting seats 100 correspondingly connected to the two ends of the rope presser 10, respectively. The symmetrical connecting seats 100 ensure that the rope presser 10 is subjected to uniform force.

[0088] On the other hand, the present application provides a rotary drilling rig, including a winch, on which a rope presser 10 is provided, and the rope presser 10 is provided with a rope presser shaft seat as in any of the above embodiments.

[0089] The winch includes a winch drum 20, which is wound with a wire rope. A rope clamp 10 is provided on the winch drum 20. The rope clamp 10 includes a frame, two tension springs 12, a pressure roller 13, and a connecting shaft 14. Two frame sleeves 11 are disposed opposite each other on the frame. The frame sleeves 11 are used to connect to the connecting seat 100. The pressure rollers 13 and the connecting shaft 14 are spaced apart on the frame. One end of the tension spring 12 is connected to the rotating platform, and the other end is connected to the frame. The pressure roller 13 is used to press the wire rope of the winch drum 20 to adjust the tension of the wire rope. The connecting shaft 14 is disposed on the side of the frame away from the winch drum 20 to enhance the support strength of the frame. The connecting seat 100 is connected to the frame sleeves 11 in a one-to-one correspondence.
