Description

Tail rope winding machine

Technical Field

The invention relates to the technical field of tail rope winding machines, in particular to a tail rope winding machine.

Background

The tail rope is often required to be wound in the electric power construction; the existing tail rope winding machine generally comprises a frame and a wire spool arranged at the frame. When the winding is performed, the tail rope is connected into the wire spool, and then the wire spool is driven to rotate by the driving component of the power part so as to finish rope winding.

Because the spool used for winding the tail rope is large in size, and the spool shaft is required to be connected with the output end of the driving assembly to realize driving rotation. The whole volume of the tail rope collecting machine is larger, so that the tail rope collecting machine is inconvenient to transport; in actual transportation, the machine body, the wire spool and the driving component of the tail rope winding machine are transported to a working place in a split mode, and then the driving component is installed at the machine body; and then the driving assembly is connected with the wire spool. Since the drive assembly is required to impart power to the spool shaft to drive it in rotation; the drive assembly itself needs to maintain high positional stability to ensure that the subsequent power output is stable. In addition, because the volume of wire reel is great, so the wire reel also needs to keep better positioning stability in the rotatory in-process in order to guarantee the stable of rolling work and go on.

The modular distribution in the existing tail rope winding machine can be further optimized so that the wire spool and the power part are more convenient to assemble (disassemble) and more stable in assembly and connection.

In addition, in the winding process, if the winding mechanism is not arranged, the tail rope cables are easy to form accumulation in the same position area of the winding reel, so that the accumulated tail ropes are easy to interfere with the machine frame to interfere with the normal use of the tail rope winding machine, and the tail rope cables are required to be wound on the winding reel uniformly through the winding mechanism.

The wire arranging seat at the wire arranging mechanism needs to realize reciprocating motion through the rotation of the wire arranging rotating shaft; meanwhile, when different tail ropes are wound, different tail rope cables may have different inner diameters, so that winding speeds are different; therefore, the moving speed of the winding displacement seat needs to be adjusted according to tail ropes with different inner diameters so as to realize uniform winding.

The existing tail rope winding machine is not provided with a reasonable speed change structure, so that the moving speed of the wire arrangement seat cannot be well and flexibly adjusted to be matched with the rotating speed of the wire spool in the tail rope winding process of the tail rope winding machine, and the smooth winding work is directly affected.

A transmission chain is usually needed between the wire arranging mechanism and the power part for transmission; the existing tail rope winding machine is not provided with an adaptive tensioning assembly for a transmission chain, so that the condition that the transmission is unstable due to insufficient tensioning degree of the transmission chain in the transmission process is caused; in addition, the tensioner assembly also needs to be preferably used in conjunction with a speed change mechanism at the time of speed change. It is difficult in the prior art to better meet these needs in tail rope reeling machines.

Disclosure of Invention

Aiming at the technical problems in the prior art, the invention provides a tail rope winding machine, which comprises a frame; the frame is provided with a wire spool for winding wires and a power part for giving power to the wire spool, and is provided with an intermediate shaft; the two ends of the intermediate shaft along the axis direction are respectively detachably connected with a power part output end serving as a first connecting end and a wire spool shaft part serving as a second connecting end; the other end of the spool shaft part far away from the intermediate shaft is detachably connected with the stand through a shaft part mounting structure; the power part is detachably assembled with the frame through an assembly structure; the frame is also provided with a chain wheel transmission assembly.

Specifically, the tail rope winding machine can stably assemble and connect the power part and the wire spool together through the intermediate shaft; on the one hand, as the intermediate shaft is directly arranged at the frame, the intermediate shaft is positioned more stably; thus compared with the direct connection of the power part output end and the wire spool shaft part; the intermediate shafts are used as connection transition, so that each rotating shaft is more stable and stable in the rotating process;

on the other hand; in the disassembly process, when the wire spool needs to be disassembled; the connection between the spool shaft and the intermediate shaft is only required to be disconnected, the power part and the intermediate shaft do not need to be treated, and the power part and the intermediate shaft are still connected so as to be convenient for subsequent normal use. The intermediate shaft is stably arranged at the frame, and compared with the direct disassembly between the spool shaft and the power part output end; because the wire spool and the power part are detachably assembled on the frame in the follow-up process, the stability of the wire spool and the power part at the frame is poorer than that of the middle shaft; so the disassembly between the intermediate shaft and the spool shaft is more convenient for the operation of users; when the power section is required to be disassembled, the same is true as described above.

In addition, the intermediate shaft can also be used to provide a mounting location for the sprocket drive assembly; because the spool and the power section are both removably mounted to the frame as a single module, and the spool shaft and the shaft end of the power section output have been provided with removable structures, it is inconvenient to mount and mate with the sprocket drive assembly. The intermediate shaft is directly arranged at the frame, and in addition, the structure of the intermediate shaft is simpler and the positioning is more stable; and can thus be used to advantage in mounting a sprocket drive assembly. And the intermediate shaft synchronously rotates along with the output end of the power part; so that power can be transmitted to the sprocket drive assembly.

It can be appreciated that in the winding process, if the winding mechanism is not provided, the tail rope cables are easily stacked in the same position area of the wire spool, so that the stacked tail ropes are easily interfered with the frame to interfere with the normal use of the tail rope winding machine, and the tail rope cables are required to be wound on the wire spool uniformly through the winding mechanism.

The wire arranging seat at the wire arranging mechanism needs to realize reciprocating motion through the rotation of the wire arranging rotating shaft; meanwhile, because the inner diameters of the tail ropes for winding are different, the moving speed of the winding displacement seat needs to be regulated to be relatively stable with the winding speed of the wire spool so as to realize uniform winding. The sprocket transmission assembly can preferably realize simultaneous transmission between the intermediate shaft, namely the spool shaft and the winding displacement rotating shaft. The transmission ratio can be selected to be proper according to actual specific conditions through the speed change mechanism; therefore, the tail rope can be uniformly wound on the wire spool.

Furthermore, the tensioning mechanism is able to tension the drive chain to ensure a stable drive. Meanwhile, when a user needs to replace gears with different teeth numbers as a driving wheel to realize speed change, the tension mechanism is adjusted to loosen the transmission chain; and then can be meshed with other driving wheels with other teeth conveniently to realize speed change.

In the invention, the inner ring plate is fixed with the spool shaft part, and the whole spool is of an integrated structure; compared with the prior art, the wire spool shaft is detachably connected with other parts at the wire spool main body in the prior art; the integrated wire spool main body has a more stable overall structure, and the wire spool shaft part and the wire spool body do not need to be assembled during assembly, so that the assembly steps are simplified.

In the winding process, the rope threading hole at the inner ring plate can be used for enabling the rope body at the head of the cable to pass through the rope threading hole in the beginning stage of the winding process of the cable, so that limit connection is formed between the inner ring plate and the cable through the rope threading hole; and then can avoid the condition that the cable slipped off the wire reel to appear effectively.

Specifically, during the actual assembly process, the assembler can move the spool shaft into the U-shaped slot in the horizontal direction and then insert the shaft positioning pin into the shaft positioning insertion hole; thereby realizing limit installation of the end of the spool shaft. When the wire spool needs to be disassembled, only the shaft part positioning pin is required to be moved out of the positioning jack, and then an assembler can move the wire spool shaft part out of the U-shaped groove along the horizontal direction; the operation is simple and convenient.

Preferably, the intermediate shaft is movably arranged at the frame through a bearing with a seat; the bearing with the seat is fixedly arranged at the frame through a fixing bolt; the intermediate shaft, the spool shaft and the power part output end are coaxially arranged.

In the invention, the second connecting block is in a cuboid structure, and the shape of the second connecting groove is matched with the second connecting block; so that the second connecting block can be directly inserted into (removed from) the second connecting groove along the axial direction of the intermediate shaft in the assembly (disassembly) process; the operation is convenient. Further, if the movement of the spool shaft to which the second connection block belongs in the axial direction is limited; the second connection block can be moved into or out of the second connection slot along the opening at the second connection slot; thereby making the whole operation process more flexible; and further effectively avoids the situation that the assembly is impossible or the disassembly is impossible due to the limit of axial movement.

It can be appreciated that the power requirement of the tail rope winding machine can be better met through the driving component, the control component and the power component; and the rotation direction, rotation speed, etc. of the spool can be controlled by controlling the driving assembly. The power part main body can be directly installed at the frame as a whole module and then directly used for winding of the tail rope winding machine. Thereby effectively avoiding the independent arrangement of the driving components at the frame and wiring again to set the control components; in this way, the installation process of the power part is complicated, and the installed devices and circuits can also influence the assembly and use of other parts of the tail rope winding machine; and cannot form a power section that can be directly modularly installed.

It can be appreciated that the above structure of the housing can preferably ensure the stability of the overall structure of the power unit main body; thereby ensuring the stability when the output end of the power part main body is used as power to drive the wire spool to rotate. And the housing can also provide a suitable operating position for the operating switch to facilitate the control operation by the user. The shell and the power part main body can be directly used for the tail rope winding machine as a whole structure by taking the shell and the power part main body as a power assembly; has better arrangement and use convenience.

In the assembly process, the limit bolt is screwed into the screw hole, so that the limit of the second matching part on the first matching part in the horizontal transverse direction can be successfully realized; and then cooperates with the aforesaid horizontal longitudinal limit and the vertical limit to jointly realize a firm location structure.

Specifically, the inner diameters of different tail rope cables are different, so that the winding speeds in the winding process are different; therefore, the moving speed of the flat cable seat needs to be matched with the winding speed; therefore, in the winding process, the cable can be uniformly and orderly coiled on the wire spool, and the situation that the cable is inconvenient to recover, such as knotting and winding, can not occur; therefore, for the tail rope winding machine, a corresponding speed change mechanism is necessary.

Specifically, the speed change mechanism in the invention does not need to be provided with a power device separately to drive the winding displacement rotating shaft; the intermediate shaft can preferably utilize the power output from the power unit. The intermediate shaft and the spool shaft are in a synchronous rotation state; because the moving speed of the winding displacement seat needs to be mutually matched with the rotating speed of the wire spool to realize a better winding effect, the problem is solved by the speed change mechanism. The large gear and the small gear which can be used as the driving wheels in the speed change mechanism are arranged at the intermediate shaft, so that a user can realize speed change by selecting the driving wheels with different tooth numbers, and further, the transmission speed suitable for winding of the tail rope winding machine is selected.

It can be understood that the speed change mechanism is simple in structure and convenient to arrange, but has an obvious effect on winding operation of the tail rope winding machine, on one hand, the wire spool and the wire arrangement mechanism can be ensured to operate simultaneously, and on the other hand, the rotating speed can be adjusted to enable the rotating speed of the wire spool and the wire arrangement mechanism to be better suitable for winding the tail rope cable when the wire spool and the wire arrangement mechanism operate simultaneously.

Specifically, the axial assembly groove is narrow, so that the positioning hole in the axial assembly groove can be only set to be smaller in diameter; therefore, the first positioning section matched with the speed change positioning pin is smaller in diameter matched with the speed change positioning pin. The diameters of the outer side through holes of the third positioning section and the outer shaft matched with the third positioning section are larger, so that on one hand, the contact surface between the third positioning section and the outer side through holes is ensured to be larger, and better positioning stability is ensured; on the other hand, the larger diameter third positioning section can also ensure that the overall strength of the shift positioning pin is sufficient.

Preferably, the transmission chain is arranged from the main driving wheel to the driven wheel in an obliquely downward direction; the winding displacement pivot is located the downside. The rotation axis of the winding displacement rotating shaft is parallel to the spool shaft; two ends of the winding displacement rotating shaft are movably arranged at the frame through bearings; the middle part of the winding displacement pivot is formed with reciprocal screw thread.

Meanwhile, the limiting rod can ensure that the wire arranging seat cannot rotate along with the reciprocating threads when moving along the axial direction of the wire arranging rotating shaft; thereby ensuring that the tail cord cable can stably pass through the flat cable guide cylinder without winding.

Detailed Description

For a further understanding of the present invention, the present invention will be described in detail with reference to examples. It is to be understood that the examples are illustrative of the present invention and are not intended to be limiting.

Example 1

Referring to fig. 1, the present embodiment provides a tail rope winding machine, which includes a frame 110; the frame 110 is provided with a wire spool for winding wires and a power part for giving power to the wire spool, and the frame 110 is provided with an intermediate shaft 140; both ends of the intermediate shaft 140 in the axial direction thereof are detachably connected to a power section output end as a first connection end and a spool shaft section as a second connection end, respectively.

Specifically, the tail rope winding machine in the present embodiment can stably assemble and connect the power part and the spool together through the intermediate shaft 140; on the one hand, since the intermediate shaft 140 is directly installed at the frame 110, the intermediate shaft 140 is positioned more stably; thus compared with the direct connection of the power part output end and the wire spool shaft part; the intermediate shaft 140 is used as a connecting transition, so that each rotating shaft is more stable and stable in the rotating process;

on the other hand; in the disassembly process, when the wire spool needs to be disassembled; the connection between the spool shaft and the intermediate shaft 140 is only required to be disconnected, no treatment is required between the power part and the intermediate shaft 140, and the power part and the intermediate shaft 140 are still connected for subsequent normal use. The intermediate shaft 140 is stably installed at the frame 110, compared to the direct disassembly between the spool shaft and the power section output; because the wire spool and the power portion are both subsequently detachably assembled on the frame 110, the stability of the wire spool and the power portion at the frame 110 is poorer than that of the intermediate shaft 140; the disassembly between the intermediate shaft 140 and the spool shaft is more convenient for the user to operate; when the power section is required to be disassembled, the same is true as described above.

In addition, the intermediate shaft 140 can also be used to provide a mounting location for the sprocket drive assembly 150; because the spool and power section are both removably mounted to the housing 110 as a single module and the spool shaft and power section output shaft ends have been provided with removable structures, it is no longer convenient to fit with the sprocket assembly 150. The intermediate shaft 140 is directly installed at the frame 110, and in addition, the intermediate shaft 140 has a simpler structure and is more stable to position; and can be preferably used to mount sprocket drive assembly 150. And the intermediate shaft 140 rotates synchronously with the power section output; so that power can be transmitted to the sprocket drive assembly 150.

Specifically, a sprocket assembly 150 is further disposed at the frame 110 in the present embodiment, and includes a speed change mechanism, where the speed change mechanism includes a driving wheel and a driven wheel; the driving wheel is positioned at the outer wall of the intermediate shaft 140 which is connected with the output end of the power part and synchronously rotates; the driven wheel is positioned at a winding displacement rotating shaft 171 of a winding displacement mechanism 170 at the frame 110; also included is a tensioning assembly including a tensioning wheel 1524 for engaging the drive chain 151 and a tensioning mount 111 mounted at the frame 110; a large gear 143 and a small gear 144 for acting as a driving wheel are formed at the intermediate shaft 140; a transmission chain 151 is arranged between the driving wheel and the driven wheel; a traction mechanism 152 which drives a tensioning wheel 1524 to rotate in a vertical plane to tension the drive chain 151 is mounted at the tensioning mount 111.

It can be appreciated that, if the wire arranging mechanism 170 is not provided in the wire winding process, the tail ropes are easily stacked in the same position area of the wire spool, so that the stacked tail ropes are easily interfered with the frame 110 to interfere with the normal use of the tail rope winding machine, and the wire arranging mechanism 170 is required to arrange the tail ropes so that the tail ropes are uniformly wound on the wire spool.

The wire housing 173 at the wire arranging mechanism 170 needs to be rotated by the wire arranging shaft 171 to realize the reciprocating motion; meanwhile, since the inner diameters of the tail ropes for winding are different, the moving speed of the wire arranging seat 173 needs to be adjusted to be relatively stable with the winding speed of the wire spool so as to realize uniform winding. The sprocket assembly 150 of the present embodiment preferably enables simultaneous transmission between the intermediate shaft 140, i.e., the spool shaft, and the winding displacement shaft 171. The transmission ratio can be selected to be proper according to actual specific conditions through the speed change mechanism; therefore, the tail rope can be uniformly wound on the wire spool.

In addition, the tensioning mechanism can tension the drive chain 151 to ensure stable drive. Meanwhile, when a user needs to replace gears with different numbers of teeth as a driving wheel to realize speed change, the tension mechanism is adjusted to loosen the transmission chain 151; and then can be meshed with other driving wheels with other teeth conveniently to realize speed change.

The application method of the tail rope winding machine in the embodiment specifically comprises the following steps of,

Step S1, assembling a tail rope collecting machine

Assembling the frame 110, the wire spool, the power part and the sprocket drive assembly 150 to form a tail rope winding machine; s2, using a tail rope collecting machine

One end of the cable is connected to the wire spool, and the power part is started to drive the wire spool to rotate and wind the cable by matching with the wire arranging seat 173 with the moving speed adjusted at the wire arranging mechanism 170; one end of the cable is connected to the wire spool, and the power part is started to drive the wire spool to rotate for winding the cable;

step S3, detaching the wire reel

Detaching both ends of the spool shaft around which the cable is wound from the shaft mounting structure 160 and the intermediate shaft 140, respectively, and then removing the spool from the housing 110;

and S4, finishing winding and obtaining the winding reel with the tail rope.

In general, the tail rope winding machine and the using method thereof in the embodiment can be assembled more conveniently to form a stable winding machine; in the use process, the tail rope cable can be stably and uniformly wound on the wire spool; after the winding is completed, the winding reel is disassembled to obtain a tail rope after the winding is completed; the tail rope can be removed from the wire spool by rotating the wire spool or manually pulling.

With reference to fig. 2-12, the present embodiment provides a modular tail rope reel suitable for embodiment 1, which enables modular assembly between the spool, the intermediate shaft 140, the power section, and the frame 110.

The modularized tail rope collecting machine in the embodiment comprises a rack 110; the frame 110 is provided with a wire spool for winding wires and a power part for giving power to the wire spool, and the frame 110 is provided with an intermediate shaft 140; the two ends of the intermediate shaft 140 along the axial direction thereof are detachably connected with a power part output end serving as a first connecting end and a wire spool shaft part serving as a second connecting end respectively; the other end of the spool shaft far from the intermediate shaft 140 is detachably connected with the frame 110 through a shaft mounting structure 160; the power section is detachably assembled with the frame 110 through the assembly structure 720.

It can be appreciated that in the transportation process, each module can be transported separately, so that the convenience is better. In addition, in the assembling process, when the power part output end and the wire spool are connected and assembled, transition can be preferably realized through the intermediate shaft 140 at the rack 110, and the assembled whole structure is more stable; thereby preferably ensuring stable progress of the winding process.

In the assembly process, the specific assembly method specifically comprises the following steps,

step S1, assembling the power part

The power part is arranged at the frame 110 through an assembling mechanism;

step S2, assembling the wire spool

One end of the spool is mounted on the housing 110 through a shaft mounting structure 160; and then the other end is connected with the intermediate shaft 140;

step S3, connecting and assembling the power part and the wire spool

Connecting the power section output with the intermediate shaft 140; the output end of the power part is in transmission connection with the shaft part of the wire spool through the intermediate shaft 140.

In detail, in the present embodiment, the spool includes a spool body 120; the spool body 120 includes spool bodies 121 arranged at both sides in the axial direction of the spool shaft; the coil ring body 121 includes an inner ring body 1211 and an outer ring body 1212 coaxial with the spool shaft axis; a ring body connecting rod 1213 for connection is arranged between the inner ring body 1211 and the outer ring body 1212; a plurality of winding rods 122 which are distributed in parallel with each other in a circumferential array are arranged between the inner rings 1211 on both sides; a plurality of winding bars 122 cooperate together for winding the tail cord. The plurality of winding bars 122 together constitute a winding part for winding the tail rope to wind up.

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 1211 is fixedly connected with the spool shaft through a through hole; a plurality of rope penetrating holes 1231 in a circumferential array are formed around the middle of the inner ring plate 123; the spool shaft portion axially extends through the through hole at both ends thereof beyond the inner ring 1211 and is detachably coupled to the shaft portion mounting structure 160 and the intermediate shaft 140, respectively.

In this embodiment, the inner ring plate 123 is fixed to the spool shaft, and the entire spool is of an integrated structure; compared with the prior art, the spool shaft is detachably connected with other parts of the spool main body 120 in the prior art; the integral structure of the integrated wire spool body 120 in this embodiment is more stable, and the wire spool shaft and the coil ring body 121 do not need to be assembled during assembly, so that the assembly steps are simplified.

In the winding process, the rope threading hole 1231 at the inner ring plate 123 can be used for passing the rope body at the head of the cable through the rope threading hole at the beginning of the winding process of the cable, so that the inner ring plate 123 and the cable form limit connection through the rope threading hole 1231; and then can avoid the condition that the cable slipped off the wire reel to appear effectively.

The shaft mounting structure 160 includes a shaft mounting block 161 mounted at the frame 110; a U-shaped groove 162 for passing through the spool shaft is formed at the shaft mounting block 161; the U-shaped groove 162 is formed with an opening in the depth direction along the horizontal direction at the shaft portion mounting block 161; a mounting bearing for movably mounting the spool shaft is arranged at the U-shaped groove 162; one side of the U-shaped groove 162 far from the wire spool is formed with a limit mounting block 163 which is U-shaped and used for limiting the mounting bearing along the axial direction of the wire spool.

The shaft portion mounting block 161 is formed with a shaft portion positioning insertion hole in the vertical direction at one side of the opening; the shaft positioning jack is inserted with a shaft positioning pin 164; the shaft portion positioning pin 164 cooperates with the circular arc-shaped side wall of the U-shaped groove 162 to form a circumferential limit for the mounting bearing and the spool shaft portion.

Specifically, during the actual assembly process, the assembler can move the spool shaft into the U-shaped slot 162 in the horizontal direction and then insert the shaft locating pin 164 into the shaft locating receptacle; thereby realizing limit installation of the end of the spool shaft. When the spool needs to be disassembled, the wire spool shaft can be moved out of the U-shaped groove 162 in the horizontal direction by an assembler only by moving the shaft positioning pin 164 out of the positioning insertion hole; the operation is simple and convenient.

Further, the other end of the spool shaft is assembled by the intermediate shaft 140; the specific structure is as follows: the intermediate shaft 140 is movably mounted at the frame 110 through a bearing 410 with a seat; the bearing 410 with the seat is fixedly installed at the frame 110 through a fixing bolt; the intermediate shaft 140, the spool shaft and the power section output are coaxially disposed.

A second connection portion 141 is formed at one end of the intermediate shaft 140 near the spool shaft; the second connection portion 141 is fixedly connected to the spool shaft to realize synchronous rotation.

The second connection portion 141 is formed with a second connection groove 1411; a second connection block 124 is formed at one end of the spool shaft near the second connection portion 141; the second connecting block 124 is in plug-in fit with the second connecting groove 1411 along the axial direction of the intermediate shaft 140; an opening for the passage of the second connection block 124 is formed at the second connection groove 1411 in the circumferential direction; a second positioning through hole 1412 is formed at the second connection block 124 and the second connection groove 1411, and the second positioning through hole 1412 at the second connection groove 1411 and the second connection block 124 are in a coaxially engaged position; a second positioning pin is inserted into the second positioning through hole 1412 to realize the fixed connection between the second connection portion 141 and the spool shaft.

In this embodiment, the second connection block 124 has a rectangular parallelepiped structure, and the shape of the second connection slot 1411 is adapted to the second connection block; the second connection block 124 can be directly inserted into (removed from) the second connection groove 1411 in the axial direction of the intermediate shaft 140 during the assembly (disassembly); the operation is convenient. Further, if the spool shaft to which the second connection block 124 belongs is limited in movement in the axial direction; the second connection block 124 may be moved into or out of the second connection slot 1411 along the opening at the second connection slot 1411; thereby making the whole operation process more flexible; and further effectively avoids the situation that the assembly is impossible or the disassembly is impossible due to the limit of axial movement.

The other end of the intermediate shaft 140 is connected to the output end of the power unit, and has the following specific structure: a first connecting part 142 is formed on one side of the intermediate shaft 140 near the output end of the power part; the first connection portion 142 is fixedly connected to the output end of the power portion to achieve synchronous rotation.

The first connection part 142 includes a square first connection block 1421; a first connecting groove 710 which is assembled and connected with the first connecting block 1421 along the axial direction of the intermediate shaft 140 is formed at the output end of the power part; an opening for the first connection block 1421 to pass through is formed at the first connection groove 710 in the circumferential direction; a first positioning through hole 1422 is formed at each of the first connection block 1421 and the first connection groove 710; the first connecting groove 710 and the first positioning through hole 1422 at the first connecting block 1421 are in the coaxially fitted position; a first positioning pin is inserted into the first positioning through hole 1422 to realize the fixed connection between the first connection part 142 and the power part output end.

In this embodiment, the first connection block 1421 and the first connection slot 710 operate in the same manner as the second connection block 124 and the second connection slot 1411.

In addition, in the present embodiment, the end portions of the first positioning pin and the second positioning pin are formed with through holes; the through holes are used for inserting the positioning buckles.

The first positioning pin (second positioning pin) can be effectively prevented from slipping off the first positioning through hole 1422 (second positioning through hole 1412) by the positioning buckle; thereby ensuring connection stability; and thus, the power transmission stability between the power section output end, the intermediate shaft 140 and the spool shaft is preferably improved.

Notably, as opposed to directly connecting the power section output to the spool shaft; in addition to the intermediate shaft 140 serving as a transitional coupling, the intermediate shaft 140 can also serve as a stable mounting location, for example, for a transmission such as a gear; and will not affect the body structure of the power section output end and the spool shaft.

Further, the power section described in the foregoing includes a power section main body 130; the power section main body 130 includes a driving assembly, a control assembly, and a power supply assembly; the output end of the driving component is used as the output end of the power part and used for giving power to the spool shaft part so as to drive the spool to rotate; the control component is used for controlling the output end of the driving component to control the rotation of the wire spool; the power supply assembly is used for giving the control assembly and the driving assembly power supply.

It can be appreciated that the power requirement of the tail rope winding machine can be better met through the driving component, the control component and the power component; and the rotation direction, rotation speed, etc. of the spool can be controlled by controlling the driving assembly. The power section body 130 of the present embodiment can be preferably mounted directly at the frame 110 as an integral module and then used directly for winding of the tail rope winding machine. So that it is possible to effectively avoid separately arranging the driving parts at the rack 110, rewiring to set the control parts; in this way, the installation process of the power part is complicated, and the installed devices and circuits can also influence the assembly and use of other parts of the tail rope winding machine; and cannot form a power section that can be directly modularly installed. And the power unit main body 130 as an integral module in the present embodiment does not affect the use and assembly of other modules of the tail rope winding machine during the installation and assembly process.

The power supply assembly includes an alternating current socket 131 and a switching power supply 132; the ac socket 131 is used for accessing an external ac circuit to supply power, and the power supply assembly further includes a storage battery and an inverter 133; the battery is used to provide power and the inverter 133 is used to convert the direct current of the battery into alternating current. During field work, power can be supplied through the storage battery.

The drive assembly includes a servo motor 134 and a reduction gearbox 135; the rotating end of the servo motor 134 is connected with the input end of the reduction gearbox 135; an output shaft of the reduction gearbox 135 serves as an output end of the driving assembly for giving power to the spool shaft; the control assembly includes a servo controller 136 and an operating switch 137; the servo controller 136 is used for controlling the starting, stopping, rotating direction and rotating speed of the servo motor 134; the operation switch 137 is connected to the servo controller 136 through a control board 920 for manual manipulation.

When in use, a user can directly control the operation switch 137, so that the operation device has better convenience.

The power part main body 130 is externally provided with a housing 810; the power section body 130 and the housing 810 together comprise a power assembly; the power section body 130 is installed inside the housing 810 and at a sidewall of the housing 810.

Specifically, the housing 810 preferably serves as a barrier for the power unit main body 130. Meanwhile, the housing 810 can also be a preferred mounting location for the various components of the power section body 130; thereby making the mounting arrangement of the various components of the power section body 130 more reasonable.

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

The top of the reduction gearbox 135 is provided with a mounting frame 910 along the vertical direction; the servo controller 136 and the control board 920 are respectively installed at both sides of the installation frame 910; a switch mounting groove 812 is formed at a side wall parallel and opposite to the side wall of the shell 810 where the opening is located; an operation switch 137 is disposed in the switch mounting groove 812 and is in communication with the control board 920.

An inverter 133 for use in cooperation with the battery is disposed at the inner bottom wall of the housing 810; a socket mounting groove 811 is formed at a sidewall of the housing 810 perpendicular to the sidewall where the opening is located; a socket mounting groove 811 is located at an upper portion of the side wall.

A heat radiation fan 930 is arranged on the inner wall of the side wall of the shell 810 opposite to the socket mounting groove 811; the socket mounting groove 811 is provided with a round-head socket and a flat-head socket which are used for being matched with the connector lug; a switching power supply 132 is disposed at an inner side wall of the housing 810; the switching power supply 132 is fixed to the inner side wall upper portion of the housing 810 near one side of the receptacle mounting groove 811 by a power supply fixing plate 1321.

A plurality of heat dissipation ports 813 are formed at the side wall of the housing 810; the heat radiation ports 813 are disposed at positions close to the servo motor 134, the switching power supply 132, the servo controller 136, and the heat radiation fan 930, respectively.

It can be appreciated that the above structure of the housing 810 can preferably ensure the stability of the overall structure of the power unit main body 130; thereby ensuring stability when the output end of the power unit body 130 is rotated as power to drive the spool. And the housing 810 can also provide an appropriate operating position for the operating switch 137 for a control operation by a user. The housing 810 and the power section main body 130 can be directly used as a whole structure for the tail rope winding machine as a power assembly; has better arrangement and use convenience.

Further, the middle power unit body 130 is assembled with the frame 110 by an assembling mechanism; specifically, the mounting structure 720 includes a first mating portion at the power portion and a second mating portion at the frame 110; the second matching part can form a limit in the horizontal and vertical directions for the first matching part so as to realize detachable assembly.

It will be appreciated that the assembled connection between the power section and the frame 110 is preferably achieved by a positive fit between the first and second mating sections.

Specifically, the first mating portion in this embodiment includes a bottom case plate 721 and a side case plate 722 of the reduction gearbox 135 at the power portion; the second mating portion includes a limiting seat 723 fixed at the frame 110; the number of the limiting seats 723 is two, and the limiting seats 723 are symmetrically distributed on two sides of the bottom plate 721 of the box body; the limit seat 723 includes a limit side plate 7231 in an L-shape in a vertical direction; the bottom of the limit side plate 7231 is fixedly connected with the horizontal end surface of the frame 110; a limiting space is formed between limiting side plates 7231 at the limiting seats 723 at the two sides; the L-shaped limiting side plate 7231 comprises a limiting transverse plate 72311 along the horizontal transverse direction and a limiting longitudinal plate 72312 along the horizontal longitudinal direction; the horizontal transverse direction is consistent with the axial direction of the spool shaft.

The inner wall of the limit transverse plate 72311 at the limit side plate 7231 is abutted against the side wall of the box side plate 722 to form the limit of the second matching part on the first matching part in the horizontal longitudinal direction; a limiting vertical plate 72313 is formed on one side of the limiting longitudinal plate 72312 at the limiting side plate 7231, which is close to the bottom plate 721 of the box body; the limiting vertical plate 72313 is parallel to the horizontal end surface where the limiting side plate 7231 is located, and the lower end surface and the horizontal end surface of the limiting vertical plate 72313 are respectively abutted against the upper end surface and the lower end surface of the bottom plate 721 of the box body to form a limit of the second matching part on the first matching part in the vertical direction.

Specifically, during the assembly process, the reduction gearbox 135 is first slid in along a position between the two limiting seats 723 until the second mating portion forms a limit in the horizontal longitudinal direction and a limit in the vertical direction for the first mating portion. Then limiting horizontally and transversely; the limiting process in the horizontal transverse direction is specifically described as follows:

an extending convex plate 72314 is formed at the position of the limit transverse plate 72311 at the position of the limit side plate 7231 in an upward extending way; the extending convex plate 72314 is positioned at one end of the limit transverse plate 72311 far from the limit longitudinal plate 72312; screw holes 72315 are formed in the extending convex plates 72314; a U-shaped through groove 7221 is formed at the side plate 722 of the box body; when the bottom plate 721 of the box body is attached to the L-shaped limit side plate 7231, the limit bolt is screwed in along the axial direction of the screw hole 72315, and enters the U-shaped through groove 7221 and is in close fit with the arc side wall of the U-shaped through groove 7221; the second matching part limits the first matching part in the horizontal and transverse directions by the abutting matching between the limiting bolts and the U-shaped through grooves 7221 and the abutting matching between the inner wall of the limiting longitudinal plate 72312 and the bottom plate 721 of the box body.

In addition, when the U-shaped through groove 7221 is not arranged at the side plate 722 of the box body, the limit bolt is screwed in along the axial direction of the screw hole 72315, and the limit bolt is directly in press fit with the side plate 722 of the box body; the limit bolt is in press fit with the box side plate 722 and is in close fit with the inner wall of the limit longitudinal plate 72312 and the box bottom plate 721, so that the limit of the second fit portion to the first fit portion in the horizontal transverse direction can be formed together.

It can be appreciated that the limiting of the second mating portion to the first mating portion in the horizontal transverse direction is mainly achieved through a limiting bolt; and can be preferably detachable. In the assembly process, the limit bolt is screwed into the screw hole 72315, so that the limit of the second matching part on the first matching part in the horizontal transverse direction can be successfully realized; and then cooperates with the aforesaid horizontal longitudinal limit and the vertical limit to jointly realize a firm location structure.

In the disassembly process, the limit bolt is screwed out of the screw hole 72315 to contact the horizontal and transverse limit; the power part can be directly moved out along the horizontal and transverse directions; thereby the disassembly is realized more conveniently.

Therefore, the assembling structure 720 in the present embodiment can more conveniently realize the detachable assembly between the power portion and the frame 110; and the assembly structure 720 is stable and convenient to disassemble.

Example 3

With reference to fig. 13-16; the present embodiment provides a sprocket assembly 150 suitable for use in embodiment 1, the specific structure of which is described below, in which the sprocket assembly 150 includes a speed change mechanism that includes a driving wheel and a driven wheel; the driving wheel is positioned at the outer wall of the intermediate shaft 140 which is connected with the output end of the power part and synchronously rotates; the driven wheel is positioned at a winding displacement rotating shaft 171 of a winding displacement mechanism 170 at the frame 110; a wire arranging seat 173 reciprocating along the axial direction of the wire arranging rotary shaft 171; also included is a tensioning assembly including a tensioning wheel 1524 for engaging the drive chain 151 and a tensioning mount 111 mounted at the frame 110; a large gear 143 and a small gear 144 for acting as a driving wheel are formed at the intermediate shaft 140; a transmission chain 151 is arranged between the driving wheel and the driven wheel; a traction mechanism 152 which drives a tensioning wheel 1524 to rotate in a vertical plane to tension the drive chain 151 is mounted at the tensioning mount 111.

Further, in use, a specific shift method of the sprocket drive assembly 150 is as follows; the method specifically comprises the following steps:

step S1: first, the tensioning wheel 1524 is separated from the transmission chain 151 by the traction mechanism 152 to release the tensioning;

step S2: another gear with different tooth numbers is selected as a driving wheel and meshed with the driving chain 151;

step S3: adjusting the traction mechanism 152 again tightens the drive chain 151;

step S4: the speed change is completed and the driven wheel is driven continuously.

Specifically, the inner diameters of different tail rope cables are different, so that the winding speeds in the winding process are different; thus, it is necessary to ensure that the moving speed of the wire arranging seat 173 is matched with the wire receiving speed; therefore, in the winding process, the cable can be uniformly and orderly coiled on the wire spool, and the situation that the cable is inconvenient to recover, such as knotting and winding, can not occur; therefore, for the tail rope winding machine, a corresponding speed change mechanism is necessary.

Specifically, the speed change mechanism in the present embodiment does not need to provide a separate power device to drive the wire arranging rotary shaft 171; the intermediate shaft 140 can preferably utilize the power output from the power unit. The intermediate shaft 140 and the spool shaft are in a synchronous rotation state; since the moving speed of the wire arranging seat 173 needs to be matched with the rotating speed of the wire spool to achieve a better winding effect, the problem is solved by the speed changing mechanism in the embodiment. The large gear 143 and the small gear 144 which can be used as driving wheels in the speed change mechanism are arranged at the middle shaft 140, so that a user can realize speed change by selecting driving wheels with different tooth numbers, and further, the transmission speed suitable for winding of the tail rope winding machine is selected.

It can be appreciated that the speed change mechanism in this embodiment has a simple structure and is convenient to be arranged, but has a relatively obvious effect on the winding operation of the tail rope winding machine, on one hand, the wire spool and the wire arrangement mechanism 170 can be ensured to operate simultaneously, and on the other hand, the rotating speed of the tail rope winding machine can be adjusted to enable the rotating speed of the wire spool and the wire arrangement mechanism to operate simultaneously, so that the rotating speed of the wire spool and the wire arrangement mechanism can be better suitable for winding the tail rope.

The intermediate shaft 140 is movably mounted at the frame 110 through a bearing 410 with a seat; the bearing 410 with the seat is fixedly installed at the frame 110 through a fixing bolt; the intermediate shaft 140, the spool shaft and the power section output end are coaxially arranged; the intermediate shaft 140 is detachably connected at both ends in the axial direction thereof to an output end at the power portion as a first connection end and a spool shaft portion as a second connection end, respectively.
