Description

Technical Field

[0001] This invention relates to the field of tail rope take-up machine technology, and more specifically, to a tail rope take-up machine and its usage method. Background Technology

[0002] In power construction, it is often necessary to wind up the tail rope; existing tail rope winding machines typically consist of a frame and a winding reel located on the frame. During winding, the tail rope is connected to the winding reel, and then the drive assembly of the power unit drives the winding reel to rotate, thus completing the winding.

[0003] Because the winding reel used for tail rope winding is relatively large, and the reel's shaft needs to connect to the output end of the drive assembly to achieve rotation, the overall size of the tail rope winding machine is large and inconvenient to transport. In actual transportation, the machine body, winding reel, and drive assembly are usually transported separately to the work site first, then the drive assembly is installed on the machine body, and finally connected to the winding reel. Since the drive assembly needs to provide power to the winding reel's shaft to drive its rotation, the drive assembly itself needs to maintain high positioning stability to ensure stable subsequent power output. Furthermore, due to the large size of the winding reel, it also needs to maintain good positioning stability during rotation to ensure stable winding operations.

[0004] The modular distribution in existing tail rope take-up machines can be further optimized to make the assembly (disassembly) of the winding reel and power unit more convenient and the assembly connection more stable.

[0005] In addition, during the winding process, if a cable laying mechanism is not set up, the tail rope cable is prone to pile up in the same area of ​​the winding reel, which can easily cause the piled-up tail rope to interfere with the frame and interfere with the normal use of the tail rope winding machine. Therefore, a cable laying mechanism is needed to lay the tail rope cable so that the tail rope is evenly wound on the winding reel.

[0006] The cable tray at the cable tray mechanism needs to achieve reciprocating motion by rotating the cable tray shaft; at the same time, because different tail ropes may have different inner diameters when winding different tail ropes, resulting in different winding speeds, the moving speed of the cable tray needs to be adjusted according to the tail ropes with different inner diameters to achieve uniform winding.

[0007] The existing tail rope winding machine is not equipped with a reasonable speed change structure, which means that the moving speed of the cable tray cannot be adjusted flexibly to match the rotation speed of the winding disc during the tail rope winding process, thus directly affecting the smooth progress of the winding work.

[0008] Furthermore, a drive chain is typically required between the cable winding mechanism and the power unit for transmission; existing tail rope take-up machines lack a suitable tensioning component for the drive chain, resulting in insufficient chain tension during transmission and potentially causing instability. Additionally, the tensioning component needs to be optimally coordinated with the speed change mechanism during gear shifting. Existing technology struggles to adequately meet these requirements in tail rope take-up machines. Summary of the Invention

[0009] To address the technical problems existing in the prior art, the present invention provides a tail rope winding machine, which includes a frame; a winding reel for winding and a power unit for providing power to the winding reel are mounted on the frame, and an intermediate shaft is provided on the frame; both ends of the intermediate shaft along its axial direction are detachably connected to the output end of the power unit as a first connection end and the shaft portion of the winding reel as a second connection end, respectively; the other end of the winding reel shaft portion far from the intermediate shaft is detachably connected to the frame through a shaft mounting structure; the power unit is detachably assembled to the frame through an assembly structure; and a sprocket drive assembly is also arranged on the frame.

[0010] Specifically, the tail rope take-up machine of the present invention can stably assemble and connect the power unit and the winding reel together through an intermediate shaft; on the one hand, since the intermediate shaft is directly installed at the frame, the positioning of the intermediate shaft is more stable; thus, compared with directly connecting the output end of the power unit and the shaft of the winding reel, the intermediate shaft as a connecting transition can make each rotating shaft more stable and smooth during rotation.

[0011] On the other hand, during disassembly, when the winding reel needs to be removed, only the connection between the winding reel shaft and the intermediate shaft needs to be disconnected. No action is required between the power unit and the intermediate shaft; they remain connected for subsequent normal use. The intermediate shaft is stably mounted on the frame. Compared to direct disassembly between the winding reel shaft and the power unit output end, the stability of both the winding reel and the power unit on the frame is lower than that of the intermediate shaft, as both are subsequently detachably mounted on the frame. Therefore, disassembly between the intermediate shaft and the winding reel shaft is easier for the user. The same principle applies when disassembling the power unit.

[0012] Furthermore, the intermediate shaft can also be used to provide a mounting position for the sprocket drive assembly. Since the winding reel and power unit are both detachably mounted on the frame as separate modules, and the shaft ends of the winding reel and power unit output already have detachable structures, it is inconvenient to install them with the sprocket drive assembly. The intermediate shaft is directly mounted on the frame; moreover, its structure is simpler and its positioning is more stable; therefore, it is better suited for mounting the sprocket drive assembly. Moreover, the intermediate shaft rotates synchronously with the power unit output, thus enabling power to be transmitted to the sprocket drive assembly.

[0013] Understandably, during the winding process, if a cable laying mechanism is not set up, the tail rope cable is prone to accumulate in the same area of ​​the winding reel, which can easily cause the accumulated tail rope to interfere with the frame and interfere with the normal use of the tail rope winding machine. Therefore, a cable laying mechanism is needed to lay the tail rope cable so that the tail rope is evenly wound on the winding reel.

[0014] The cable guide seat at the cable guide mechanism needs to achieve reciprocating motion through the rotation of the cable guide shaft. Simultaneously, because the inner diameters of the tail ropes being wound vary, the moving speed of the cable guide seat needs to be adjusted to maintain relative stability with the winding speed of the winding reel to achieve uniform winding. The sprocket drive assembly in this invention can effectively achieve simultaneous transmission between the intermediate shaft (i.e., the winding reel shaft) and the cable guide shaft. Furthermore, the speed change mechanism allows for the selection of a suitable transmission ratio based on specific circumstances, thereby ensuring that the tail rope is wound more evenly onto the winding reel.

[0015] In addition, the tensioning mechanism can tension the drive chain to ensure stable transmission. Furthermore, when it is necessary to change gears with different numbers of teeth as the driving wheel to achieve speed change, the user can first adjust the tensioning mechanism to loosen the drive chain; then, it can be easily engaged with other driving wheels with different numbers of teeth to achieve speed change.

[0016] Preferably, the winding reel includes a winding reel body; the winding reel body includes winding rings arranged on both sides of the winding reel shaft axially upward; the winding rings include an inner ring and an outer ring coaxial with the axis of the winding reel shaft; a ring connecting rod for connection is provided between the inner ring and the outer ring; multiple winding rods arranged in a circumferential array and parallel to each other are arranged between the inner rings on both sides; the multiple winding rods cooperate to wind the tail rope.

[0017] Preferably, an inner ring plate is formed in the inner ring body; a through hole is formed in the middle of the inner ring plate; the inner ring body is fixedly connected to the winding disc shaft through the through hole; a plurality of rope-passing holes are formed in a circumferential array around the middle of the inner ring plate; the two ends of the winding disc shaft extend out of the inner ring body through the through hole and are detachably connected to the shaft mounting structure and the intermediate shaft, respectively.

[0018] In this invention, the inner ring plate is fixed to the winding disc shaft, and the entire winding disc is an integrated structure. Compared with the prior art, the winding disc shaft is detachably connected to other parts of the winding disc body. The integrated winding disc body of this invention has a more stable overall structure, and there is no need to assemble the winding disc shaft and the winding ring body during assembly, thus simplifying the assembly process.

[0019] During the winding process, the rope-passing hole at the inner ring plate can be used to pass the rope of the cable head through it at the beginning of the cable winding process, so that the inner ring plate and the cable form a limiting connection through the rope-passing hole; thereby effectively preventing the cable from slipping off the winding reel.

[0020] Preferably, the shaft mounting structure includes a shaft mounting block mounted on the frame; a U-shaped groove is formed at the shaft mounting block for passing through the winding spool shaft; the depth direction of the U-shaped groove is horizontal and an opening is formed at the shaft mounting block; a mounting bearing for movably mounting the winding spool shaft is provided at the U-shaped groove; a U-shaped limiting mounting block is formed on the side of the U-shaped groove away from the winding spool for limiting the mounting bearing along the axial direction of the winding spool.

[0021] Preferably, the shaft mounting block has a vertical shaft positioning hole on one side of the opening; a shaft positioning pin is inserted into the shaft positioning hole; the shaft positioning pin and the arc-shaped sidewall of the U-shaped groove cooperate to limit the circumferential movement of the bearing and the winding spool shaft.

[0022] Specifically, during the actual assembly process, the assembler can move the winding reel shaft into the U-shaped groove horizontally, and then insert the shaft locating pin into the shaft locating hole; thus achieving the limiting installation of this end of the winding reel shaft. When disassembly is required, simply remove the shaft locating pin from the locating hole, and then the assembler can move the winding reel shaft out of the U-shaped groove horizontally; the operation is simple and convenient.

[0023] Preferably, the intermediate shaft is movably mounted to the frame via a seated bearing; the seated bearing is fixedly mounted to the frame via fixing bolts; the intermediate shaft, the winding reel shaft, and the power unit output end are coaxially arranged.

[0024] Preferably, a first connecting portion is formed on the side of the intermediate shaft near the output end of the power unit; the first connecting portion is used to be fixedly connected to the output end of the power unit to achieve synchronous rotation.

[0025] Preferably, the first connecting part includes a square first connecting block; a first connecting groove is formed at the output end of the power part, which is axially connected to the first connecting block along the intermediate shaft; a first positioning through hole is formed at both the first connecting block and the first connecting groove; when the first positioning through hole at the first connecting groove and the first connecting block are in a coaxially mating position; a first positioning pin is inserted into the first positioning through hole to achieve a fixed connection between the first connecting part and the output end of the power part.

[0026] Preferably, a second connecting portion is formed at one end of the intermediate shaft near the winding disc shaft portion; the second connecting portion is used to be fixedly connected to the winding disc shaft portion to achieve synchronous rotation.

[0027] Preferably, the second connecting portion has a second connecting groove; a second connecting block is formed at one end of the winding spool shaft near the second connecting portion; the second connecting block and the second connecting groove are axially inserted into each other along the intermediate shaft; an opening for the second connecting block to pass through is formed circumferentially at the second connecting groove; a second positioning through hole is formed at the second connecting block and the second connecting groove, and when the second positioning through hole at the second connecting groove and the second connecting block is in a coaxially engaged position; a second positioning pin is inserted into the second positioning through hole to achieve a fixed connection between the second connecting portion and the winding spool shaft.

[0028] In this invention, the second connecting block has a cuboid shape, and the shape of the second connecting groove is adapted to it; therefore, during assembly (disassembly), the second connecting block can be directly inserted into (removed from) the second connecting groove along the axial direction of the intermediate shaft; operation is convenient. Furthermore, if the axial movement of the winding reel shaft to which the second connecting block belongs is restricted, the second connecting block can be moved into or out of the second connecting groove along the opening at the second connecting groove; thus making the entire operation process more flexible; and effectively avoiding situations where assembly or disassembly is impossible due to axial movement restrictions.

[0029] Preferably, the ends of the first and second positioning pins are formed with through holes; the through holes are used to insert positioning buckles.

[0030] Preferably, the power unit includes a power unit body; the power unit body includes a drive component, a control component, and a power supply component; the output end of the drive component serves as the output end of the power unit and is used to provide power to the winding disc shaft to drive the winding disc to rotate; the control component is used to control the output end of the drive component to control the rotation of the winding disc; and the power supply component is used to provide power to the control component and the drive component.

[0031] Understandably, the power requirements of the tail rope take-up machine can be better met by using drive components, control components, and power supply components; and the rotation direction and speed of the winding disc can be controlled by controlling the drive components. The main power unit of this invention can be preferably installed directly as a single module on the frame and then used directly for winding the tail rope take-up machine. This effectively avoids the need to separately arrange drive components on the frame and then lay out wiring to install control components; such an arrangement would be cumbersome, and the installed components and wiring might affect the assembly and use of other parts of the tail rope take-up machine; furthermore, it would not be possible to form a directly modular power unit. Furthermore, the main power unit of this invention, as a single module, will not affect the use and assembly of other modules of the tail rope take-up machine during installation and assembly.

[0032] Preferably, the power supply assembly includes an AC socket and a switching power supply; the AC socket is used to connect to an external AC circuit for power supply, and the power supply assembly also includes a battery and an inverter; the battery is used to provide power, and the inverter is used to convert the DC power from the battery into AC power.

[0033] Preferably, the drive assembly includes a servo motor and a gearbox; the rotating end of the servo motor is connected to the input end of the gearbox; the output shaft of the gearbox serves as the output end of the drive assembly to provide power to the winding disc shaft; the control assembly includes a servo controller and an operation switch; the servo controller is used to control the start, stop, rotation direction, and rotation speed of the servo motor; the operation switch is connected to the servo controller via a control board for manual operation.

[0034] Preferably, the main body of the power unit is provided with a housing; the main body of the power unit and the housing together constitute the powertrain; the main body of the power unit is installed inside the housing and on the side wall of the housing.

[0035] Preferably, an opening is formed on one side wall of the housing; the output end of the gearbox is located at the opening; the bottom of the gearbox is positioned and installed with the frame through an assembly structure; a servo motor is provided at the input end of the gearbox and connected thereto; the servo motor is located inside the housing.

[0037] Preferably, an inverter for use with a battery is arranged on the inner bottom wall of the housing; a socket mounting groove is formed on the side wall of the housing perpendicular to the side wall where the opening is located; the socket mounting groove is located on the upper part of the side wall.

[0038] Preferably, a cooling fan is provided on the inner wall of the side wall opposite to the socket mounting slot of the housing; the socket mounting slot is provided with a round-head socket and a flat-head socket for use with the wiring head; a switching power supply is arranged on the inner side wall of the housing; the switching power supply is fixed to the upper part of the inner side wall of the housing near the socket mounting slot by a power supply fixing plate.

[0039] Preferably, the side wall of the housing is provided with multiple heat dissipation vents; the heat dissipation vents are respectively arranged near the servo motor, switching power supply, servo controller and cooling fan.

[0040] Understandably, the aforementioned structure of the housing effectively ensures the overall structural stability of the power unit, thereby guaranteeing the stability of the output end of the power unit when driving the winding reel. Furthermore, the housing provides a suitable operating position for the control switch, facilitating user operation. The housing and power unit, as a power assembly, can be ideally integrated and directly used as a single unit in a tail rope take-up machine, offering superior layout and ease of use.

[0041] Preferably, the assembly structure includes a first mating part located at the power unit and a second mating part located at the frame; the second mating part can provide horizontal and vertical constraints on the first mating part to achieve detachable assembly.

[0042] Preferably, the first mating part includes a gearbox base plate and a gearbox side plate at the power unit; the second mating part includes a limiting seat fixed to the frame; there are two limiting seats, which are symmetrically distributed on both sides of the gearbox base plate; the limiting seat includes a limiting side plate that is L-shaped in the vertical direction; the bottom of the limiting side plate is fixedly connected to the horizontal end face at the frame; a limiting space is formed between the limiting side plates at the two limiting seats; the L-shaped limiting side plate includes a limiting horizontal plate in the horizontal direction and a limiting vertical plate in the horizontal direction; the horizontal direction is consistent with the axis direction of the winding disc shaft.

[0043] Preferably, the inner wall of the limiting horizontal plate at the limiting side plate abuts against the side wall of the box side plate to form a second mating part that limits the first mating part in the horizontal longitudinal direction; a limiting vertical plate is formed on the side of the limiting vertical plate near the bottom plate of the box; the limiting vertical plate is parallel to the horizontal end face of the limiting side plate, and the lower end face and horizontal end face of the limiting vertical plate abut against the upper end face and lower end face of the bottom plate of the box, respectively, to form a second mating part that limits the first mating part in the vertical direction.

[0044] Preferably, an extension protrusion extends upward from the limiting horizontal plate at the limiting side plate; the extension protrusion is located at one end of the limiting horizontal plate far from the limiting vertical plate; the extension protrusion is provided with a screw hole; a U-shaped through groove is formed at the box side plate; when the box bottom plate is in contact with the L-shaped limiting side plate, a limiting bolt is screwed in along the axis of the screw hole, the limiting bolt enters the U-shaped through groove and abuts against the arc side wall of the U-shaped through groove; the abutting fit between the limiting bolt and the U-shaped through groove and the abutting fit between the inner wall of the limiting vertical plate and the box bottom plate together form the second mating part limiting the first mating part in the horizontal direction.

[0045] Preferably, an extension protrusion extends upward from the limiting horizontal plate at the limiting side plate; the extension protrusion is located at one end of the limiting horizontal plate far from the limiting vertical plate; the extension protrusion is provided with a screw hole; when the bottom plate of the box is in contact with the L-shaped limiting side plate, a limiting bolt is screwed in along the axis of the screw hole, and the limiting bolt presses against the box side plate; the pressing against the box side plate and the contact between the inner wall of the limiting vertical plate and the bottom plate of the box together form a second mating part that limits the first mating part in the horizontal direction.

[0046] Understandably, the horizontal lateral positioning of the second mating part relative to the first mating part is mainly achieved through a limiting bolt; and it also allows for good disassembly. During assembly, screwing the limiting bolt into the bolt hole successfully achieves the horizontal lateral positioning of the second mating part relative to the first mating part; thus, together with the aforementioned horizontal longitudinal positioning and vertical positioning, a stable positioning structure is achieved.

[0047] During disassembly, simply unscrewing the limit bolt from the screw hole allows it to contact the horizontal limit; and the power unit can be moved directly along the horizontal direction, thus facilitating disassembly.

[0048] Therefore, the assembly structure in this invention can easily realize the detachable assembly between the power unit and the frame; and the assembly structure is stable and easy to disassemble.

[0049] Preferably, the sprocket drive assembly includes a speed change mechanism, which includes a drive wheel and a driven wheel; the drive wheel is located on the outer wall of an intermediate shaft that is connected to and rotates synchronously with the output end of the power unit; the driven wheel is located at the cable winding shaft of the cable winding mechanism at the frame; a cable winding seat reciprocates along the axial direction at the cable winding shaft; and a tensioning assembly, which includes a tensioning wheel for meshing with the drive chain and a tensioning mounting seat mounted on the frame; a large gear and a small gear with different numbers of teeth are formed at the intermediate shaft to serve as the drive wheel; a drive chain is arranged between the drive wheel and the driven wheel; and a traction mechanism is installed at the tensioning mounting seat to drive the tensioning wheel to rotate in a vertical plane to tension the drive chain.

[0050] Specifically, since different tail ropes have different inner diameters, the winding speed during the winding process varies. Therefore, it is necessary to ensure that the moving speed of the cable tray is matched with the winding speed. This ensures that the cable can be evenly and neatly wound on the winding spool during the winding process without knots or tangles that make it difficult to retract. Therefore, it is necessary to set up a corresponding speed change mechanism for the tail rope winding machine.

[0051] Specifically, the speed-changing mechanism in this invention does not require a separate power unit to drive the cable winding shaft; the power output from the power unit can be better utilized through the intermediate shaft. Furthermore, the intermediate shaft and the winding reel shaft rotate synchronously; since the moving speed of the cable carrier needs to be matched with the rotational speed of the winding reel to achieve a better winding effect, this invention solves this problem through a speed-changing mechanism. The large and small gears, which can serve as the driving wheels, are located on the intermediate shaft in the speed-changing mechanism, allowing the user to select different numbers of teeth on the driving wheels to achieve speed changes, thereby selecting a suitable transmission speed for the tail rope winding machine.

[0052] Understandably, the speed change mechanism in this invention has a simple structure and is easy to arrange, but it can have a significant effect on the winding operation of the tail rope winding machine. On the one hand, it can ensure that the winding reel and the wire laying mechanism work at the same time. On the other hand, it can also adjust the speed so that the speed when the two work at the same time is better suited to the winding of the tail rope cable.

[0053] Preferably, the intermediate shaft is movably mounted to the frame via a seated bearing; the seated bearing is fixedly mounted to the frame via fixing bolts; the intermediate shaft, the winding reel shaft, and the output end of the power unit are coaxially arranged; both ends of the intermediate shaft along its axial direction are detachably connected to the output end of the power unit (as the first connection end) and the winding reel shaft (as the second connection end), respectively; an outer shaft coaxial with the intermediate shaft is formed on its outer wall; a large gear and a small gear are arranged on the outer wall of the outer shaft; the intermediate shaft and the outer shaft can move relative to each other along the axial direction; an axial mounting groove extending along its axial direction is formed on the intermediate shaft; two positioning holes are formed in the axial mounting groove; an outer through hole is formed on the outer shaft; the distance between the two positioning holes is consistent with the distance between the large gear and the small gear; the intermediate shaft and the outer shaft are fixedly connected by a speed-changing positioning pin.

[0054] Specifically, during use, the outer shaft and the intermediate shaft can be connected and separated via a speed-changing positioning pin. When separated, the user can adjust the position of the outer shaft axially to select a suitable driving wheel (large gear or small gear) to mesh with the driven wheel via a transmission chain. After the position of the outer shaft is adjusted, it can be connected to the intermediate shaft via the speed-changing positioning pin to achieve synchronous rotation. Thus, the rotation of the intermediate shaft is transmitted to the driven wheel via the driving wheel and the transmission chain, and the driven wheel can drive the cable routing shaft to rotate to achieve cable routing.

[0055] Preferably, the gear shifting positioning pin has a first positioning section, a second positioning section, and a third positioning section with gradually increasing diameter along its axial direction; the first positioning section is used to position and cooperate with the positioning hole at the axial assembly groove; the third positioning section is used to position and cooperate with the outer through hole at the outer shaft; and the second positioning section is used to connect the first positioning section and the third positioning section.

[0056] Specifically, due to the narrowness of the axial assembly groove, the positioning holes within it can only be set to a smaller diameter; therefore, the first positioning section that mates with the gear shift positioning pin also uses a smaller diameter. The third positioning section and the outer through hole on the outer shaft that mates with it have larger diameters. On the one hand, this ensures a larger contact surface between the third positioning section and the outer through hole to ensure better positioning stability; on the other hand, the larger diameter of the third positioning section also ensures sufficient overall strength of the gear shift positioning pin.

[0057] Preferably, the drive chain is arranged diagonally downwards from the driving wheel to the driven wheel; the cable winding shaft is located on the lower side. The rotation axis of the cable winding shaft is parallel to the shaft of the winding reel; both ends of the cable winding shaft are movably mounted to the frame via bearings; a reciprocating thread is formed in the middle of the cable winding shaft.

[0058] Preferably, the reciprocating thread is provided with a cable tray that reciprocates and slides with it; the upper part of the cable tray is provided with a cable guide cylinder; one end of the cable tray shaft is provided with a crank mounting part for mounting a manual crank handle. The frame is also provided with a limiting rod parallel to the cable tray shaft; the cable tray is formed with a limiting hole that slides with the limiting rod.

[0059] Understandably, before the cable laying operation begins, the user can manually crank the cable laying shaft to adjust the position of the cable laying seat so that it aligns with the initial fixed position of the cable head and the winding reel. At the same time, the limit rod ensures that the cable laying seat does not rotate with the reciprocating thread when moving axially along the cable laying shaft; thus ensuring that the tail rope cable can pass stably through the cable laying guide cylinder without tangling.

[0060] Preferably, the traction mechanism includes a tensioning mounting plate disposed at a tensioning mounting seat; a threaded seat is formed at the tensioning mounting seat; the threaded seat is used to screw in a nut and press against the tensioning mounting plate to position it. The tensioning mounting plate includes a first tensioning plate and a second tensioning plate arranged in an alternating manner; a tensioning rotating plate is movably connected to the inner wall of the side of the second tensioning plate away from the drive chain; the tensioning rotating plate rotates in a vertical plane; a tensioning screw is connected to the end of the tensioning rotating plate; a tensioning wheel is mounted at the tensioning screw and meshes with the drive chain.

[0061] Preferably, the tensioning screw has a first screw connection part, a second screw connection part, and a third screw connection part formed sequentially along its axial direction; the outer wall of the first screw connection part is used to movably connect with the tensioning wheel, and the tensioning wheel rotates freely relative to the first screw connection part; the outer wall of the second screw connection part cooperates with the tensioning mounting cylinder formed at the end of the tensioning rotating plate to fix it; the outer wall of the third screw connection part is threaded; a nut is screwed into the thread of the third screw connection part and pressed against the tensioning mounting cylinder to achieve a positioning connection between the tensioning screw and the tensioning mounting cylinder; a traction spring is provided between the first tensioning plate and the tensioning rotating plate to pull the tensioning rotating plate to tension the transmission chain.

[0062] This invention also provides a method of use, based on the aforementioned tail rope take-up machine, which specifically includes the following steps:

[0063] Step S1: Assembly of the tail rope take-up machine

[0064] The frame, winding reel, power unit, and sprocket drive assembly are assembled to form a tail rope take-up machine;

[0065] Step S2, Using the tail rope take-up machine

[0066] Connect one end of the cable to the winding reel, start the power unit to drive the winding reel to rotate, and work with the cable tray at the cable tray mechanism to adjust the moving speed to wind up the cable.

[0067] Step S3: Disassemble the winding reel

[0068] Disconnect both ends of the winding reel shaft with the cable wound from the shaft mounting structure and the intermediate shaft respectively, and then remove the winding reel from the frame;

[0069] Step S4: Complete the winding and obtain a winding reel with a tail rope.

[0070] In summary, the tail rope winding machine and its usage method described in this invention can be easily assembled into a stable winding machine; and during use, it can stably and evenly wind the tail rope cable onto the winding reel; after winding is completed, the winding reel can be removed to obtain the wound tail rope; subsequently, the tail rope can be removed from the winding reel by rotating the winding reel or by manually pulling it.

[0087] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0088] Example 1

[0089] Combination Figure 1This embodiment provides a tail rope winding machine, which includes a frame 110; a winding reel for winding and a power unit for providing power to the winding reel are mounted on the frame 110, and an intermediate shaft 140 is provided on the frame 110; both ends of the intermediate shaft 140 along its axial direction are detachably connected to the output end of the power unit as a first connection end and the shaft of the winding reel as a second connection end.

[0090] Specifically, in this embodiment, the tail rope take-up machine can stably assemble and connect the power unit and the winding reel together through the intermediate shaft 140. On the one hand, since the intermediate shaft 140 is directly installed at the frame 110, the positioning of the intermediate shaft 140 is relatively stable. Therefore, compared with directly connecting the output end of the power unit and the shaft of the winding reel, using the intermediate shaft 140 as a connecting transition can make each rotating shaft more stable and smooth during rotation.

[0091] On the other hand, during disassembly, when it is necessary to remove the winding reel, only the connection between the winding reel shaft and the intermediate shaft 140 needs to be disconnected. No action is required between the power unit and the intermediate shaft 140; they remain connected for subsequent normal use. The intermediate shaft 140 is stably mounted on the frame 110. Compared to direct disassembly between the winding reel shaft and the power unit output end, since both the winding reel and the power unit are subsequently detachably mounted on the frame 110, their stability on the frame 110 is inferior to that of the intermediate shaft 140. Therefore, disassembly between the intermediate shaft 140 and the winding reel shaft is easier for the user. The same principle applies when the power unit needs to be disassembled.

[0092] Furthermore, the intermediate shaft 140 can also provide a mounting position for the sprocket drive assembly 150. Since the winding reel and power unit are both detachably mounted as separate modules on the frame 110, and the shaft ends of the winding reel and power unit outputs already have detachable structures, it is inconvenient to install them with the sprocket drive assembly 150. The intermediate shaft 140 is directly mounted on the frame 110. Moreover, the intermediate shaft 140 has a simpler structure and more stable positioning; therefore, it is better suited for mounting the sprocket drive assembly 150. Furthermore, the intermediate shaft 140 rotates synchronously with the power unit output, thereby transmitting power to the sprocket drive assembly 150.

[0093] Specifically, in this embodiment, a sprocket drive assembly 150 is also arranged at the frame 110, which includes a speed change mechanism, including a drive wheel and a driven wheel; the drive wheel is located on the outer wall of the intermediate shaft 140 connected to and rotating synchronously with the output end of the power unit; the driven wheel is located at the cable winding shaft 171 of the cable winding mechanism 170 at the frame 110; it also includes a tensioning assembly, which includes a tensioning wheel 1524 for meshing with the transmission chain 151 and a tensioning mounting seat 111 installed at the frame 110; a large gear 143 and a small gear 144 are formed at the intermediate shaft 140 for serving as the drive wheel; a transmission chain 151 is arranged between the drive wheel and the driven wheel; a traction mechanism 152 is installed at the tensioning mounting seat 111 to drive the tensioning wheel 1524 to rotate in the vertical plane to tension the transmission chain 151.

[0094] Understandably, during the winding process, if the cable laying mechanism 170 is not set up, the tail rope cable is likely to accumulate in the same area of ​​the winding reel, which may cause the accumulated tail rope to interfere with the frame 110 and interfere with the normal use of the tail rope winding machine. Therefore, the cable laying mechanism 170 is needed to lay the tail rope cable so that the tail rope is evenly wound on the winding reel.

[0095] The cable tray 173 at the cable tray mechanism 170 needs to rotate via the cable tray shaft 171 to achieve reciprocating motion. Simultaneously, because the inner diameters of the tail ropes being wound are different, the moving speed of the cable tray 173 needs to be adjusted to maintain relative stability with the winding speed of the winding reel to achieve uniform winding. In this embodiment, the sprocket drive assembly 150 can effectively achieve simultaneous transmission between the intermediate shaft 140 (i.e., the winding reel shaft) and the cable tray shaft 171. Furthermore, the speed change mechanism allows for the selection of a suitable transmission ratio based on specific circumstances, thereby ensuring that the tail rope is wound more evenly onto the winding reel.

[0096] Furthermore, the tensioning mechanism can tension the drive chain 151 to ensure stable transmission. Additionally, when it is necessary to change gears with different numbers of teeth as the driving wheel to achieve speed change, the user can first adjust the tensioning mechanism to loosen the drive chain 151; then, it can be easily engaged with other driving wheels with different numbers of teeth to achieve speed change.

[0097] The method of using a tail rope winding machine in this embodiment specifically includes the following steps:

[0098] Step S1: Assembly of the tail rope take-up machine

[0099] The frame 110, winding reel, power unit and sprocket drive assembly 150 are assembled to form a tail rope take-up machine.

[0100] Step S2, Using the tail rope take-up machine

[0101] Connect one end of the cable to the winding reel, start the power unit to drive the winding reel to rotate, and work with the cable tray 173 at the cable tray mechanism 170, which has its movement speed adjusted, to wind up the cable; connect one end of the cable to the winding reel, start the power unit to drive the winding reel to rotate, and wind up the cable.

[0102] Step S3: Disassemble the winding reel

[0103] Disconnect both ends of the winding reel shaft with the cable wound from the shaft mounting structure 160 and the intermediate shaft 140 respectively, and then remove the winding reel from the frame 110.

[0104] Step S4: Complete the winding and obtain a winding reel with a tail rope.

[0105] In summary, the tail rope winding machine and its usage method described in this embodiment can be easily assembled into a stable winding machine; and during use, it can stably and evenly wind the tail rope cable onto the winding reel; after winding is completed, the winding reel can be removed to obtain the wound tail rope; subsequently, the tail rope can be removed from the winding reel by rotating the winding reel or by manually pulling it.

[0106] Example 2

[0107] Combination Figures 2-12 This embodiment provides a modular tail rope take-up machine applicable to Embodiment 1, which can realize modular assembly between the winding reel, intermediate shaft 140, power unit and frame 110.

[0108] The modular tail rope take-up machine in this embodiment includes a frame 110; a winding reel for winding and a power unit for providing power to the winding reel are mounted on the frame 110; an intermediate shaft 140 is provided on the frame 110; both ends of the intermediate shaft 140 along its axial direction are detachably connected to the output end of the power unit as a first connection end and the shaft portion of the winding reel as a second connection end; the other end of the winding reel shaft portion away from the intermediate shaft 140 is detachably connected to the frame 110 through a shaft mounting structure 160; the power unit is detachably assembled to the frame 110 through an assembly structure 720.

[0109] Specifically, the modular tail rope take-up machine in this embodiment mainly consists of several main modules, including a frame 110, a winding reel, and a power unit, and each module can be detachably assembled.

[0110] To be explained in detail, the winding reel and the frame 110: one end of the winding reel shaft is detachably assembled to the frame 110 via the shaft mounting structure 160, and the other end of the winding reel shaft is detachably connected to the intermediate shaft 140 at the frame 110.

[0111] Power unit and frame 110: The power unit and frame 110 can be detachably assembled via assembly structure 720.

[0112] Power unit and winding reel: The power unit and winding reel are detachably connected via intermediate shaft 140; the output end of the power unit and the shaft of the winding reel are detachably connected to the two ends of the intermediate shaft 140 in the axial direction.

[0113] Understandably, during transportation, the various modules can be transported separately, thus providing greater convenience. Furthermore, during assembly, when connecting the power unit output end and the winding reel, the intermediate shaft 140 at the frame 110 can facilitate a smooth transition, resulting in a more stable overall structure after assembly; thereby ensuring the stable progress of the winding process.

[0114] The specific assembly method during the assembly process includes the following steps:

[0115] Step S1: Assembly of the power unit

[0116] The power unit is mounted on the frame 110 via an assembly structure;

[0117] Step S2: Assembly of the winding reel

[0118] One end of the winding reel is mounted on the frame 110 via the shaft mounting structure 160; the other end is then connected to the intermediate shaft 140.

[0119] Step S3: Connection and assembly between the power unit and the winding reel

[0120] The output end of the power unit is connected to the intermediate shaft 140; the output end of the power unit is connected to the winding disc shaft via the intermediate shaft 140 for transmission.

[0121] In this embodiment, the winding reel includes a winding reel body 120; the winding reel body 120 includes winding rings 121 arranged on both axially upward sides of the winding reel shaft; the winding rings 121 include an inner ring 1211 and an outer ring 1212 coaxial with the axis of the winding reel shaft; a ring connecting rod 1213 for connection is provided between the inner ring 1211 and the outer ring 1212; a plurality of winding rods 122 arranged in a circumferential array and parallel to each other are arranged between the inner rings 1211 on both sides; the plurality of winding rods 122 cooperate to wind the tail rope. The plurality of winding rods 122 together form a winding section for winding the tail rope for coiling.

[0122] An inner ring plate 123 is formed at the inner ring body 1211; a through hole is formed at the middle of the inner ring plate 123; the inner ring body 1211 is fixedly connected to the winding reel shaft through the through hole; a plurality of rope holes 1231 arranged in a circular array are formed around the middle of the inner ring plate 123; the two ends of the winding reel shaft extend out of the inner ring body 1211 through the through hole and are detachably connected to the shaft mounting structure 160 and the intermediate shaft 140 respectively.

[0123] In this embodiment, the inner ring plate 123 is fixed to the winding reel shaft, and the entire winding reel is an integrated structure. Compared with the prior art, the prior art detachably connects the winding reel shaft to other parts of the winding reel body 120. In this embodiment, the integrated winding reel body 120 has a more stable overall structure, and there is no need to assemble the winding reel shaft and the winding ring 121 during assembly, thus simplifying the assembly process.

[0124] During the winding process, the rope hole 1231 at the inner ring plate 123 can be used to pass the rope of the cable head through it at the beginning of the cable winding process, so that the inner ring plate 123 and the cable form a limiting connection through the rope hole 1231; thereby effectively preventing the cable from slipping off the winding reel.

[0125] The shaft mounting structure 160 includes a shaft mounting block 161 mounted on the frame 110; a U-shaped groove 162 for passing through the winding spool shaft is formed at the shaft mounting block 161; the depth direction of the U-shaped groove 162 is horizontal and an opening is formed at the shaft mounting block 161; a mounting bearing for movably mounting the winding spool shaft is provided at the U-shaped groove 162; a U-shaped limiting mounting block 163 for limiting the mounting bearing along the axial direction of the winding spool is formed on the side of the U-shaped groove 162 away from the winding spool.

[0126] The shaft mounting block 161 has a vertical shaft positioning hole on one side of the opening; a shaft positioning pin 164 is inserted into the shaft positioning hole; the shaft positioning pin 164 and the arc-shaped sidewall of the U-shaped groove 162 cooperate to limit the bearing and the winding spool shaft in the circumferential direction.

[0127] Specifically, during the actual assembly process, the assembler can move the winding reel shaft into the U-shaped groove 162 horizontally, and then insert the shaft positioning pin 164 into the shaft positioning hole; thus achieving the limiting installation of this end of the winding reel shaft. When disassembly is required, simply remove the shaft positioning pin 164 from the positioning hole, and then the assembler can move the winding reel shaft out of the U-shaped groove 162 horizontally; the operation is simple and convenient.

[0128] Furthermore, the other end of the winding reel shaft is assembled via an intermediate shaft 140; the specific structure is as follows: the intermediate shaft 140 is movably mounted on the frame 110 via a seated bearing 410; the seated bearing 410 is fixedly mounted on the frame 110 via fixing bolts; the intermediate shaft 140, the winding reel shaft, and the power unit output end are coaxially arranged.

[0129] A second connecting portion 141 is formed at one end of the intermediate shaft 140 near the winding reel shaft portion; the second connecting portion 141 is used to be fixedly connected to the winding reel shaft portion to achieve synchronous rotation.

[0130] The second connecting portion 141 has a second connecting groove 1411; a second connecting block 124 is formed at one end of the winding spool shaft near the second connecting portion 141; the second connecting block 124 and the second connecting groove 1411 are axially inserted into each other along the intermediate shaft 140; an opening for the second connecting block 124 to pass through is formed circumferentially at the second connecting groove 1411; a second positioning through hole 1412 is formed at the second connecting block 124 and the second connecting groove 1411; when the second positioning through hole 1412 at the second connecting groove 1411 and the second connecting block 124 is in a coaxially engaged position; a second positioning pin is inserted into the second positioning through hole 1412 to achieve a fixed connection between the second connecting portion 141 and the winding spool shaft.

[0131] In this embodiment, the second connecting block 124 has a cuboid shape, and the shape of the second connecting groove 1411 is adapted to it; therefore, during assembly (disassembly), the second connecting block 124 can be directly inserted into (removed from) the second connecting groove 1411 along the axial direction of the intermediate shaft 140; the operation is convenient. Furthermore, if the axial movement of the winding reel shaft to which the second connecting block 124 belongs is restricted, the second connecting block 124 can be moved into or out of the second connecting groove 1411 along the opening at the second connecting groove 1411; thus making the entire operation process more flexible; and effectively avoiding situations where assembly or disassembly is impossible due to axial movement restrictions.

[0132] The other end of the intermediate shaft 140 is used to connect to the output end of the power unit. The specific structure is as follows: a first connecting part 142 is formed on the side of the intermediate shaft 140 near the output end of the power unit; the first connecting part 142 is used to be fixedly connected to the output end of the power unit to achieve synchronous rotation.

[0133] The first connecting part 142 includes a square first connecting block 1421; a first connecting groove 710 is formed at the output end of the power unit and is axially connected to the first connecting block 1421 along the intermediate shaft 140; an opening for the first connecting block 1421 to pass through is formed in the circumferential direction at the first connecting groove 710; a first positioning through hole 1422 is formed at both the first connecting block 1421 and the first connecting groove 710; when the first positioning through hole 1422 at the first connecting groove 710 and the first connecting block 1421 is in a coaxially engaged position; a first positioning pin is inserted into the first positioning through hole 1422 to achieve a fixed connection between the first connecting part 142 and the output end of the power unit.

[0134] In this embodiment, the operation between the first connecting block 1421 and the first connecting groove 710 is the same as that of the second connecting block 124 and the second connecting groove 1411.

[0135] In addition, in this embodiment, the ends of the first positioning pin and the second positioning pin are formed with through holes; the through holes are used to insert positioning buckles.

[0136] The positioning buckle effectively prevents the first positioning pin (second positioning pin) from slipping out of the first positioning through hole 1422 (second positioning through hole 1412), thus ensuring connection stability and further improving the power transmission stability between the power unit output end, intermediate shaft 140 and winding disc shaft.

[0137] It is worth noting that, compared to directly connecting the power unit output end and the winding reel shaft, the intermediate shaft 140 not only serves as a transitional connection, but also acts as a stable mounting position for components such as gears; and it does not affect the main structure of the power unit output end and the winding reel shaft.

[0138] Furthermore, the power unit mentioned above includes a power unit body 130; the power unit body 130 includes a drive assembly, a control assembly, and a power supply assembly; the output end of the drive assembly serves as the output end of the power unit and is used to provide power to the winding disc shaft to drive the winding disc to rotate; the control assembly is used to control the output end of the drive assembly to control the rotation of the winding disc; the power supply assembly is used to provide power to the control assembly and the drive assembly.

[0139] Understandably, the drive assembly, control assembly, and power supply assembly can better meet the power requirements of the tail rope take-up machine; and the rotation direction and speed of the winding disc can be controlled by controlling the drive assembly. In this embodiment, the main body 130 of the power unit can be installed directly as a whole module on the frame 110 and then used directly for winding the tail rope take-up machine. This effectively avoids the need to separately arrange the drive component and then lay wiring to set up the control component on the frame 110; in this case, the installation process of the power unit is more complicated, and the installed components and wiring may affect the assembly and use of other components of the tail rope take-up machine; and it cannot form a power unit that can be directly modularly installed. Furthermore, in this embodiment, the main body 130 of the power unit, as a whole module, will not affect the use and assembly of other modules of the tail rope take-up machine during installation and assembly.

[0140] The power supply assembly includes an AC power socket 131 and a switching power supply 132; the AC power socket 131 is used to connect to an external AC circuit for power supply, and the power supply assembly also includes a battery and an inverter 133; the battery is used to provide power, and the inverter 133 is used to convert the DC power from the battery into AC power. When working in the field, power can be supplied by the battery.

[0141] The drive assembly includes a servo motor 134 and a gearbox 135; the rotating end of the servo motor 134 is connected to the input end of the gearbox 135; the output shaft of the gearbox 135 serves as the output end of the drive assembly to provide power to the winding reel shaft; the control assembly includes a servo controller 136 and an operation switch 137; the servo controller 136 is used to control the start, stop, rotation direction, and rotation speed of the servo motor 134; the operation switch 137 is connected to the servo controller 136 via a control board 920 for manual operation.

[0142] When in use, the user can directly control it by operating switch 137, which has good convenience.

[0143] The main body 130 of the power unit is provided with a housing 810 on the outside; the main body 130 of the power unit and the housing 810 together constitute the power assembly; the main body 130 of the power unit is installed inside the housing 810 and on the side wall of the housing 810.

[0144] Specifically, the housing 810 effectively encloses and protects the main body of the power unit 130. Simultaneously, the housing 810 also serves as an optimal mounting location for the various components of the main body of the power unit 130, resulting in a more rational arrangement of these components.

[0145] An opening is formed on one side wall of the housing 810; the output end of the gearbox 135 is located at the opening; the bottom of the gearbox 135 is positioned and installed with the frame 110 through the assembly structure 720; a servo motor 134 is provided at the input end of the gearbox 135 and connected thereto; the servo motor 134 is located inside the housing 810.

[0146] The top of the gearbox 135 is provided with a vertical mounting bracket 910; a servo controller 136 and a control board 920 are respectively mounted on both sides of the mounting bracket 910; a switch mounting groove 812 is formed on the side wall of the housing 810 that is parallel to the side wall where the opening is located; an operating switch 137 that is communicatively connected to the control board 920 is arranged in the switch mounting groove 812.

[0147] An inverter 133 for use with a storage battery is arranged on the inner bottom wall of the housing 810; a socket mounting groove 811 is formed on the side wall of the housing 810 perpendicular to the side wall where the opening is located; the socket mounting groove 811 is located on the upper part of the side wall.

[0148] A cooling fan 930 is provided on the inner wall of the side wall opposite to the socket mounting groove 811 of the housing 810; the socket mounting groove 811 is provided with a round socket and a flat socket for use with the wiring head; a switching power supply 132 is arranged on the inner side wall of the housing 810; the switching power supply 132 is fixed to the upper part of the inner side wall of the housing 810 near the socket mounting groove 811 by a power fixing plate 1321.

[0149] The side wall of the housing 810 is provided with multiple heat dissipation vents 813; the heat dissipation vents 813 are respectively arranged near the servo motor 134, the switching power supply 132, the servo controller 136 and the cooling fan 930.

[0150] Understandably, the aforementioned structure of the housing 810 effectively ensures the overall structural stability of the power unit body 130, thereby guaranteeing the stability of the output end of the power unit body 130 when driving the winding reel to rotate. Furthermore, the housing 810 provides a suitable operating position for the operating switch 137, facilitating user control. The housing 810 and the power unit body 130, as a power assembly, can be ideally integrated and directly used as a single unit in a tail rope take-up machine, offering superior layout and ease of use.

[0151] Furthermore, the aforementioned power unit body 130 and frame 110 are assembled together by an assembly structure; specifically, the assembly structure 720 includes a first mating part located at the power unit and a second mating part located at the frame 110; the second mating part can limit the first mating part in the horizontal and vertical directions to achieve detachable assembly.

[0152] Understandably, the assembly connection between the power unit and the frame 110 can be better achieved through the limiting fit between the first mating part and the second mating part.

[0153] Specifically, in this embodiment, the first mating part includes a housing bottom plate 721 and a housing side plate 722 of the gearbox 135 at the power unit; the second mating part includes a limiting seat 723 fixed at the frame 110; there are two limiting seats 723, which are symmetrically distributed on both sides of the housing bottom plate 721; the limiting seat 723 includes a limiting side plate 7231 that is L-shaped in the vertical direction; the bottom of the limiting side plate 7231 is fixedly connected to the horizontal end face at the frame 110; a limiting space is formed between the limiting side plates 7231 at the two limiting seats 723; the L-shaped limiting side plate 7231 includes a limiting horizontal plate 72311 in the horizontal transverse direction and a limiting vertical plate 72312 in the horizontal longitudinal direction; the horizontal transverse direction is consistent with the axial direction of the winding reel shaft.

[0154] The inner wall of the limiting horizontal plate 72311 at the limiting side plate 7231 abuts against the side wall of the box side plate 722 to form a second mating part that limits the first mating part in the horizontal longitudinal direction; a limiting vertical plate 72313 is formed on the side of the limiting vertical plate 72312 near the box bottom plate 721 at the limiting side plate 7231; the limiting vertical plate 72313 is parallel to the horizontal end face of the limiting side plate 7231, and the lower end face and horizontal end face of the limiting vertical plate 72313 abut against the upper end face and lower end face of the box bottom plate 721 respectively to form a second mating part that limits the first mating part in the vertical direction.

[0155] Specifically, during assembly, the gearbox 135 is first slid into place between the two limiting seats 723 until the second mating part forms a horizontal longitudinal limit and a vertical limit on the first mating part. Then, horizontal lateral limiting is performed; the horizontal lateral limiting process is described in detail below:

[0156] An extension protrusion 72314 extends upward from the limiting horizontal plate 72311 at the limiting side plate 7231; the extension protrusion 72314 is located at one end of the limiting vertical plate 72312 far from the limiting horizontal plate 72311; a screw hole 72315 is provided at the extension protrusion 72314; a U-shaped through groove 7221 is formed at the box side plate 722; when the box bottom plate 721 is in contact with the L-shaped limiting side plate 7231, a limiting bolt is screwed in along the axial direction of the screw hole 72315, and the limiting bolt enters into the U-shaped through groove 7221 and abuts against the arc side wall of the U-shaped through groove 7221; the abutting fit between the limiting bolt and the U-shaped through groove 7221 and the abutting fit between the inner wall of the limiting vertical plate 72312 and the box bottom plate 721 together form the second mating part limiting the first mating part in the horizontal direction.

[0157] In addition, when there is no U-shaped through groove 7221 at the side plate 722 of the box, the limiting bolt is screwed in along the axial direction of the screw hole 72315, and the limiting bolt directly presses against the side plate 722 of the box; the pressing against the side plate 722 of the box and the close contact between the inner wall of the limiting longitudinal plate 72312 and the bottom plate 721 of the box can also jointly form the second mating part to limit the first mating part in the horizontal direction.

[0158] Understandably, the horizontal lateral positioning of the second mating part relative to the first mating part is mainly achieved through a limiting bolt; and it also allows for better disassembly. During assembly, screwing the limiting bolt into the screw hole 72315 successfully achieves the horizontal lateral positioning of the second mating part relative to the first mating part; thus, together with the aforementioned horizontal longitudinal positioning and vertical positioning, a stable positioning structure is achieved.

[0159] During disassembly, simply unscrewing the limit bolt out of the screw hole 72315 allows it to contact the horizontal limit; and the power unit can be moved out directly along the horizontal direction; thus, disassembly is achieved relatively easily.

[0160] Therefore, the assembly structure 720 in this embodiment can easily realize the detachable assembly between the power unit and the frame 110; and the assembly structure 720 is stable and easy to disassemble.

[0161] Example 3

[0162] Combination Figures 13-16 This embodiment provides a sprocket drive assembly 150 suitable for Embodiment 1, the specific structure of which is as follows: In this embodiment, the sprocket drive assembly 150 includes a speed change mechanism, which includes a driving wheel and a driven wheel; the driving wheel is located on the outer wall of the intermediate shaft 140, which is connected to and rotates synchronously with the output end of the power unit; the driven wheel is located at the cable winding shaft 171 of the cable winding mechanism 170 at the frame 110; a cable winding seat 173 reciprocates along the axial direction of the cable winding shaft 171; and... The system includes a tensioning assembly, which includes a tensioning wheel 1524 for meshing with the drive chain 151 and a tensioning mounting seat 111 mounted on the frame 110; a large gear 143 and a small gear 144 are formed at the intermediate shaft 140 to serve as the driving wheel; the drive chain 151 is arranged between the driving wheel and the driven wheel; and a traction mechanism 152 is mounted at the tensioning mounting seat 111 to drive the tensioning wheel 1524 to rotate in a vertical plane to tension the drive chain 151.

[0163] Furthermore, in use, the specific speed change method of the sprocket drive assembly 150 is as follows; it specifically includes the following steps:

[0164] Step S1: First, the tensioning wheel 1524 is disengaged from the transmission chain 151 by the traction mechanism 152 to release the tension;

[0165] Step S2: Select another gear with a different number of teeth as the driving gear and mesh it with the transmission chain 151;

[0166] Step S3: Adjust the traction mechanism 152 to tension the transmission chain 151 again;

[0167] Step S4: The gear shift is completed and continues to drive the driven wheel.

[0168] Specifically, since different tail ropes have different inner diameters, the winding speed during the winding process is different. Therefore, it is necessary to ensure that the moving speed of the cable tray 173 is matched with the winding speed. This ensures that the cable can be evenly and neatly wound on the winding spool during the winding process without knotting or tangling, which would make it difficult to retract. Therefore, it is necessary to set up a corresponding speed change mechanism for the tail rope winding machine.

[0169] Specifically, in this embodiment, the speed change mechanism does not require a separate power unit to drive the cable tray shaft 171; the power output from the power unit can be better utilized through the intermediate shaft 140. Furthermore, the intermediate shaft 140 and the winding reel shaft rotate synchronously; because the moving speed of the cable tray 173 needs to be matched with the rotational speed of the winding reel to achieve a better winding effect, this embodiment solves this problem through a speed change mechanism. The large gear 143 and small gear 144, which can serve as driving wheels, are located on the intermediate shaft 140 in the speed change mechanism. Therefore, the user can select different numbers of teeth on the driving wheels to achieve speed change, thereby selecting a transmission speed suitable for the tail rope winding machine.

[0170] Understandably, the speed change mechanism in this embodiment has a simple structure and is easy to arrange, but it can have a significant effect on the winding of the tail rope winding machine. On the one hand, it can ensure that the winding reel and the wire laying mechanism 170 work at the same time. On the other hand, it can also adjust the speed so that the speed when the two work at the same time is better suited to the winding of the tail rope cable.

[0171] The intermediate shaft 140 is movably mounted on the frame 110 via a seated bearing 410; the seated bearing 410 is fixedly mounted on the frame 110 via fixing bolts; the intermediate shaft 140, the winding reel shaft, and the output end of the power unit are coaxially arranged; the two ends of the intermediate shaft 140 along its axial direction are detachably connected to the output end of the power unit as the first connection end and the winding reel shaft as the second connection end, respectively.

[0172] An outer shaft 145, coaxial with the intermediate shaft 140, is formed on its outer wall. A large gear 143 and a small gear 144 are arranged on the outer wall of the outer shaft 145. The intermediate shaft 140 and the outer shaft 145 can move relative to each other along the axial direction. An axial mounting groove 146 extending along the axial direction is formed on the intermediate shaft 140. Two positioning holes 1461 are formed in the axial mounting groove 146. An outer through hole is formed on the outer shaft 145. The distance between the two positioning holes 1461 is consistent with the distance between the large gear 143 and the small gear 144. The intermediate shaft 140 and the outer shaft 145 are fixedly connected by a speed-changing positioning pin 147.

[0173] Specifically, during use, the outer shaft 145 and the intermediate shaft 140 can be connected and disconnected via a speed-changing positioning pin 147. When disconnected, the user can adjust the position of the outer shaft 145 axially to select a suitable driving wheel (large gear 143 or small gear 144) to mesh with the driven wheel via the transmission chain 151. After the position of the outer shaft 145 is adjusted, it can be connected to the intermediate shaft 140 via the speed-changing positioning pin 147 to achieve synchronous rotation. Thus, the rotation of the intermediate shaft 140 is transmitted to the driven wheel via the driving wheel and the transmission chain 151, and the driven wheel can drive the cable routing shaft 171 to rotate to achieve cable routing.

[0174] The gear shift positioning pin 147 has a first positioning section 1471, a second positioning section 1472, and a third positioning section 1473 with gradually increasing diameters along its axial direction; the first positioning section 1471 is used to position and cooperate with the positioning hole 1461 at the axial assembly groove 146; the third positioning section 1473 is used to position and cooperate with the outer through hole at the outer shaft 145; the second positioning section 1472 is used to connect the first positioning section 1471 and the third positioning section 1473.

[0175] Specifically, because the axial mounting groove 146 is relatively narrow, the positioning hole 1461 within the axial mounting groove 146 can only be set to a smaller diameter; therefore, the first positioning section 1471 that mates with the gear shift positioning pin 147 is also selected with a smaller diameter. The third positioning section 1473 and the outer through hole at the outer shaft 145 that mates with it have larger diameters. On the one hand, this ensures that the contact surface between the third positioning section 1473 and the outer through hole is larger, thus ensuring better positioning stability; on the other hand, the larger diameter of the third positioning section 1473 also ensures that the overall strength of the gear shift positioning pin 147 is sufficient.

[0176] The drive chain 151 is arranged diagonally downward from the driving wheel to the driven wheel; the cable winding shaft 171 is located on the lower side. The rotation axis of the cable winding shaft 171 is parallel to the shaft of the winding reel; both ends of the cable winding shaft 171 are movably mounted on the frame 110 through bearings; a reciprocating thread 172 is formed in the middle of the cable winding shaft 171.

[0177] Specifically, due to the weight of the tail rope itself, the tail rope will basically lie flat against the ground during the winding process; therefore, the cable laying mechanism 170 needs to be arranged below to ensure the stable operation of the cable laying.

[0178] A cable tray 173 is provided at the reciprocating thread 172, which is in reciprocating sliding engagement with the thread; a cable guide cylinder 174 is provided on the upper part of the cable tray 173; a crank mounting part 175 for mounting a manual crank handle is provided at one end of the cable tray shaft 171. A limiting rod 176 parallel to the cable tray shaft 171 is also provided at the frame 110; a limiting hole is formed at the cable tray 173, which is in sliding engagement with the limiting rod 176.

[0179] Understandably, before the cable laying operation begins, the user can manually crank the cable laying shaft 171 to adjust the position of the cable laying seat 173 so that it aligns with the initial fixed position of the cable head and the winding reel. At the same time, the limit rod 176 ensures that the cable laying seat 173 does not rotate with the reciprocating thread 172 when moving axially along the cable laying shaft 171; thus ensuring that the tail rope cable can pass stably through the cable laying guide cylinder 174 without tangling.

[0180] The traction mechanism 152 includes a tension mounting plate 1521 located at a tension mounting seat 111; a threaded seat is formed at the tension mounting seat 111; the threaded seat is used to screw in a nut and press against the tension mounting plate 1521 to position it. The tension mounting plate 1521 includes a first tension plate 15211 and a second tension plate 15212 arranged alternately; a tension rotating plate 1522 is movably connected to the end of the second tension plate 15212 at one side of the inner wall of the drive chain 151; the tension rotating plate 1522 rotates in a vertical plane. A tension screw 1523 is connected to the end of the tension rotating plate 1522; a tension wheel 1524 is installed at the tension screw 1523 and meshes with the drive chain 151. A traction spring is provided between the first tension plate 15211 and the tension rotating plate 1522 for pulling the tension rotating plate 1522 to tension the drive chain 151.

[0181] Specifically, during use, the traction spring uses one end located at the first tensioning plate 15211 as a fixed end to pull the other end located at the tensioning rotating plate 1522; thereby, the tensioning rotating plate 1522 drives the tensioning wheel 1524 at the tensioning screw 1523 to tension the transmission chain 151; the operation is simple and can stably achieve a better tensioning effect.

[0182] In addition, the tensioning mounting plate 1521 can provide a stable mounting position for the tensioning plate 1522, and this mounting position can be located on one side of the transmission chain 151. Therefore, compared with the installation method of directly mounting the tensioning plate 1522 to the frame 110, the tensioning mounting plate 1521 can better avoid the influence of the transmission chain 151 on the installation process, and thus make it easier for users to perform installation operations.

[0183] On the other hand, the tensioning mounting plate 1521 can also provide a fixed position for one end of the traction spring; thereby enabling a better traction effect on the other end, which is the movable end, to drive the tensioning wheel 1524 to tension the transmission chain 151.

[0184] The tensioning screw 1523 has a first screw connection portion 15231, a second screw connection portion 15232, and a third screw connection portion 15233 sequentially formed along its axial direction. The outer wall of the first screw connection portion 15231 is used to movably connect with the tensioning wheel 1524, and the tensioning wheel 1524 rotates freely relative to the first screw connection portion 15231. The outer wall of the second screw connection portion 15232 cooperates with the tensioning mounting cylinder formed at the end of the tensioning rotating plate 1522 for fixed connection. The outer wall of the third screw connection portion 15233 has a thread. A nut is screwed into the thread of the third screw connection portion 15233 and presses against the tensioning mounting cylinder to achieve a positioning connection between the tensioning screw 1523 and the tensioning mounting cylinder.

[0185] Specifically, the first screw connection portion 15231 of the tensioning screw 1523 provides a better installation position for the tensioning wheel 1524; because the tensioning screw 1523 can be disassembled and adjusted relatively flexibly, the tensioning wheel 1524 installed at the tensioning screw 1523 can also be adjusted flexibly. Furthermore, the second screw connection portion 15232 can abut against the tensioning mounting cylinder to form a positioning, ensuring a stable connection between the tensioning screw 1523 and the tensioning rotating plate 1522; and the tensioning mounting cylinder can also better limit the tensioning screw 1523 in the circumferential direction.

[0186] Furthermore, the threaded engagement between the third screw connection 15233 and the nut can better limit the tensioning screw 1523 in the axial direction; therefore, the tensioning screw 1523 can have better positioning stability at the tensioning plate 1522; thereby ensuring stable meshing between the tensioning wheel 1524 and the transmission chain 151 for tensioning.
