Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A wire rope stranding machine 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. As shown in fig. 1 to 14, a wire rope cabling machine 100 according to an embodiment of the present invention includes a wire frame 1, a main shaft 21, a rear large plate 221, a middle large plate 222, a front large plate 223, a wire distribution plate 24, a first shaft 231, a second shaft 232, and a strand tension detecting device 3.

The main shaft 21 is horizontally disposed. For convenience of presentation, the horizontal direction is shown by arrow E in fig. 1. Each of the rear large disc 221, the middle large disc 222, and the front large disc 223 is fitted over the spindle 21, and the middle large disc 222 is located between the rear large disc 221 and the front large disc 223 in the axial direction of the spindle 21. The distributing board 24 is sleeved on the main shaft 21, and the front large board 223 is located between the middle large board 222 and the distributing board 24 in the axial direction of the main shaft 21. The first shaft 231 is provided on the middle large disk 222, and the second shaft 232 is provided on the front large disk 223. A bobbin 1 is provided on each of the first shaft 231 and the second shaft 232, the bobbin 1 being rotatably provided. And the rope strand tension detection device 3, wherein the rope strand tension detection device 3 is arranged on the end surface of the front large disc 223 far away from the middle large disc 222. In order to make the technical solution of the present application easier to understand, the following describes the technical solution of the present application further by taking the main shaft 21 extending in the front-rear direction as an example. Wherein the front-back direction is indicated by arrow F in fig. 1.

As shown in fig. 1 to 8, the bobbin 1 according to the embodiment of the present invention includes a body 11, a pulley 12, a first timing pulley 13, a second timing pulley 14, a timing belt 15, and a driving member 16.

The reel 12 is provided on the body 11. The first synchronous belt wheel 13 is arranged on the body 11, the first synchronous belt wheel 13 is connected with the wire wheel 12, and the first synchronous belt wheel 13 and the wire wheel 12 can rotate synchronously. The timing belt 15 is a closed loop, and the timing belt 15 is fitted over each of the second timing pulley 14 and the first timing pulley 13. A driver 16 is connected to the second timing pulley 14 for driving the second timing pulley 14 in rotation. Wherein 200 for manufacturing a steel cord can be wound on the reel 12.

The driving member 16 drives the second synchronous pulley 14 to rotate, and the second synchronous pulley 14 drives the synchronous belt 15 to rotate so as to drive the first synchronous pulley 13 to rotate at the same time. The first synchronous belt wheel 13 rotates to synchronously drive the wire wheel 12 to rotate. Therefore, the greater (smaller) the rotational speed of the driver 16, the greater (smaller) the rotational speed of the second synchronous pulley 14, the greater (smaller) the rotational speed of the first synchronous pulley 13, and the greater (smaller) the rotational speed of the pulley 12. I.e. the rotational speed of the driver 16, the rotational speed of the second synchronous pulley 14, the rotational speed of the first synchronous pulley 13 and the rotational speed of the pulley 12 are directly proportional. In the case of paying out, the faster the rotation speed of the reel 12, the faster the paying out speed of the strands 200 on the reel 12, and the smaller the tension of the strands 200. In the case of paying out, the slower the rotation speed of the reel 12, the slower the paying out speed of the strands 200 on the reel 12, and the greater the tension of the strands 200. That is, the tension of the strand 200 is inversely related to the rotational speed of the reel 12 in the case of paying out. The tension of the strand 200 is thus inversely proportional to the rotational speed of the driver 16, and the tension of the strand 200 can be varied by varying the rotational speed of the driver 16. In the case where the strands 200 on the wire reel 12 are taken up, the strands 200 become large in tension.

When the tension of the strand 200 needs to be increased, the paying-off speed of the strand 200 on the wire wheel 12 can be reduced, namely, the rotating speed of the wire wheel 12 is adjusted to be low, and the tension of the strand 200 is increased under the condition that the forward tension of the strand 200 is not changed. Or, when the tension of the strand 200 needs to be increased, the reel 12 can be reversed, and even if the reel 12 takes up the strand 200, the tension of the strand 200 will be increased because the strand 200 is simultaneously subjected to a forward-directed tension. When the tension of the strand 200 needs to be reduced, the paying-off speed of the strand 200 on the pulley 12 can be increased, that is, the rotating speed of the pulley 12 is increased, and under the condition that the forward tension of the strand 200 is not changed, the tension of the strand 200 is reduced due to the fact that the paying-off speed is increased. The tension of the strand 200 can thus be adjusted by controlling the driver 16.

As shown in fig. 1 to 11, the wire rope cabling machine 100 includes a main shaft 21, a rear large disc 221, a middle large disc 222, a front large disc 223, a wire distribution disc 24, a first shaft 231, a second shaft 232, a wire stand 1, a wire wheel 12, and a strand tension detecting device 3.

Each of the rear large disc 221, the middle large disc 222 and the front large disc 223 is sleeved on the spindle 21, the middle large disc 222 is positioned in front of the rear large disc 221, and the front large disc 223 is positioned in front of the middle large disc 222. The distributing disc 24 is sleeved on the main shaft 21, and the distributing disc 24 is positioned in front of the front large disc 223.

The first shaft 231 is provided on the middle large disk 222, and the second shaft 232 is provided on the front large disk 223. A bobbin 1 is provided on each of the first shaft 231 and the second shaft 232, the bobbin 1 being rotatably provided. For example, the bobbin 1 is rotatably provided on each of the first shaft 231 and the second shaft 232. Alternatively, the first shaft 231 is rotatably provided on the middle large disc 222, the second shaft 232 is rotatably provided on the front large disc 223, and the bobbin 1 is fixedly provided on each of the first shaft 231 and the second shaft 232.

The bobbin 1 can thereby revolve around the axis of the main shaft 21 along with the rear large disc 221, the middle large disc 222, and the front large disc 223, and can also rotate around the axis of the first shaft 231 and the second shaft 232. The wire wheel 12 is arranged on the wire frame 1.

Optionally, the second shaft 232 is a hollow shaft. As shown in fig. 1, the wire rope cabling machine 100 further includes a carrier roller 25, the carrier roller 25 is provided on the wire frame 1, and the carrier roller 25 is located between the pulley 12 and the front large disc 223 in the axial direction of the main shaft 21. Specifically, the carrier roller 25 is located in front of the pulley 12, and the carrier roller 25 is located behind the front large disc 223.

Wherein the strands 200 can be wound on the reel 12. The free ends of the strands 200 wound on the reel 12 pass through the idler 25, the second shaft 232, the reel 16 and the distribution plate 24 in sequence.

It will be understood by those skilled in the art that the number of each of the bobbins 1, the pulley 12, the first shaft 231, the second shaft 232, the idlers 25, and the strand tension detecting devices 3 corresponds to the number of the strands 200.

As described above, since the rear large disc 221, the middle large disc 222, and the front large disc 223 revolve around the axis of the main shaft 21, the line frame 1 also revolves around the axis of the main shaft 21. Control of the drive member 16 is thus difficult to achieve via conventional wired communication cables.

Thus, in some embodiments, the creel 1 further includes an electrical cabinet 17, a first omnidirectional antenna 18 and wireless signal receiving means 19.

As shown in fig. 3-6, an electric control box 17 is provided on the body 11, and the electric control box 17 is electrically connected to the driving member 16. Optionally, the drive 16 is an electric motor. The electric control box 17 is used for controlling the driving part 16 and can adjust the rotating speed of the driving part 16.

As shown in fig. 3-6, the first omnidirectional antenna 18 is disposed on the body 11, and the first omnidirectional antenna 18 is electrically connected to the electric cabinet 17. The first omnidirectional antenna 18 is used for receiving signals of the electric cabinet 17 and sending wireless signals, and is used for receiving wireless signals and transmitting the wireless signals to the electric cabinet 17. As an example, the first omnidirectional antennas 18 include two, and the two first omnidirectional antennas 18 are disposed opposite to each other, and are disposed on the upper surface and the lower surface of the body 11, respectively. This arrangement enables the first omnidirectional antenna 18 to better transmit wireless signals.

The wireless signal receiving means 19 is connected in wireless communication with the first omnidirectional antenna 18. The wireless signal receiving means 19 is capable of sending a wireless signal to the first omnidirectional antenna 18, the first omnidirectional antenna 18 transmitting a signal to the electric control box 17, which signal may be a control signal for controlling the driving member 16, the electric control box 17 controlling the driving member 16 according to the control signal. The first omnidirectional antenna 18 may also transmit a signal to the wireless signal receiving device 19, and transmit information of the electric cabinet 17 to the wireless signal receiving device 19.

In some embodiments, as shown in fig. 3-6, the electronic control box 17 includes a servo drive 171, an industrial wireless lan client 172 and a power supply 173.

The driver 16 has a power supply interface and an encoder interface, the servo driver 171 is electrically connected to the power supply interface through a power cable 161, and the servo driver 171 is electrically connected to the encoder interface through an encoder cable 162.

The servo drive 171 is electrically connected to the driver 16 by a power cable 161 and an encoder cable 162. The servo driver 171 is used to provide a driving force to the driver 16. The servo drive 171 is also used to control the rotational speed of the driver 16.

The industrial wlan client 172 is connected to the servo driver 171, and the industrial wlan client 172 is connected to the first omnidirectional antenna 18. Alternatively, as shown in fig. 6, the industrial wlan client 172 is connected to the servo driver 171 through an industrial ethernet line 1721, as an example. The servo driver 171 transmits the industrial ethernet signal to the industrial wireless lan client 172 through the industrial ethernet line 1721, whereby the first omni-directional antenna 18 transmits the industrial ethernet signal delivered to the industrial wireless lan client 172 in the form of radio waves.

Similarly, the radio wave received by the first omnidirectional antenna 18 is converted into an industrial ethernet signal by the industrial wlan client 172, and the industrial ethernet signal is transmitted to the servo driver 171 through the industrial ethernet line 1721.

A power supply 173 is connected to the servo drive 171 and the industrial wlan client 172. A power supply 173 provides power to the servo driver 171 and the industrial wlan client 172. Optionally, power supply 173 converts 380VAC power to 24VDC power.

In some embodiments, as shown in fig. 6, wireless signal receiving device 19 includes a second omnidirectional antenna 191 and an industrial wireless local area network PLC access terminal 192. The second omnidirectional antenna 191 is in wireless communication with the first omnidirectional antenna 18 such that the second omnidirectional antenna 191 receives signals transmitted by the first omnidirectional antenna 18 and the first omnidirectional antenna 18 receives signals transmitted by the second omnidirectional antenna 191. The industrial wireless local area network PLC access terminal 192 is connected to the second omnidirectional antenna 191. The second omni-directional antenna 191 can receive the wireless signal transmitted by the first omni-directional antenna 18, and the industrial wireless local area network PLC access terminal 192 converts the wireless signal into an industrial ethernet signal. The industrial wlan PLC access terminal 192 is connected to the main PLC system, and can access the converted industrial ethernet signal to the main PLC system.

Similarly, the PLC access end 192 of the industrial wireless local area network can convert the control signal fed back by the PLC control system into a wireless signal, and the wireless signal is sent by the second omnidirectional antenna 191 and received by the first omnidirectional antenna 18. The control signals fed back by the PLC control system include control signals that control the driver 16.

According to the steel wire rope forming machine 100 provided by the embodiment of the invention, the electric control box 17, the first omnidirectional antenna 18 and the wireless signal receiving device 19 are arranged, so that the wireless transmission of the control signal of the driving part 16 can be conveniently and easily realized.

Further, as shown in fig. 3 to 6, the bobbin 1 further includes a tension pulley 4, the tension pulley 4 is disposed on the body 11, and the tension pulley 4 abuts against the timing belt 15 so as to be able to adjust the tension of the timing belt 15.

Further, the synchronous belt 15 is provided with teeth at equal intervals, and the first synchronous pulley 13 and the second synchronous pulley 14 are both provided with tooth grooves matched with the teeth. So that a better fit can be achieved between the primary timing pulley 13, the secondary timing pulley 14 and the timing belt 15.

In some embodiments, as shown in fig. 1-6, the first timing pulley 13 is coaxially disposed with the pulley 12, and one end of the pulley 12 is connected to the first timing pulley 13 and the other end is connected to the body 11. The connection of the first body 11 of the reel 12 is a rotatable connection of the reel 12, that is, the reel 12 is rotatably connected with the first body 11. In order to enable the first synchronous pulley 13 and the pulley 12 to rotate synchronously, the first synchronous pulley 13 has at least one connecting piece 131, and the pulley 12 has a connecting groove matched with the connecting piece 131, and the connecting piece is matched in the connecting groove. Through the connecting groove and the connecting piece 131, the first synchronous pulley 13 and the pulley 12 can realize synchronous rotation.

The strand tension detecting device 3 according to the embodiment of the present invention includes a second body 31, a gland 32, a second pressure sensor 33, a wire wheel bracket 34, a preload member 35, and a wire wheel 36.

The gland 32 is disposed on the second body 31, and a mounting cavity 311 is defined between the second body 31 and the gland 32. The second pressure sensor 33 is disposed in the mounting cavity 311, and the wire wheel support 34 is movably disposed in the mounting cavity 311 along a predetermined direction. A preload member 35 is provided on the gland 32, and the preload member 35 is engaged with the thread wheel bracket 34 so that the thread wheel bracket 34 abuts on the second pressure sensor 33. The wire passing wheel 36 is rotatably provided on the wire passing wheel bracket 34.

The second body 31 of the strand tension detecting device 3 is arranged on the end surface of the front large disc 223 far away from the middle large disc 222, and the wire passing wheel bracket 34 of the strand tension detecting device 3 is movably arranged in the installation cavity 311 of the strand tension detecting device 3 along the axial direction of the main shaft 21. That is, the preset direction coincides with the axial direction of the main shaft 21. Since the main shaft 21 is horizontally disposed, the axial direction of the main shaft 21 coincides with the horizontal direction (first horizontal direction), that is, the preset direction coincides with the horizontal direction. Wherein the horizontal direction is indicated by arrow E in fig. 1.

When a wire rope is manufactured by the wire rope forming machine 100, the strands 200 on the drum 12 pass through the wire guide 36 and the distribution plate 24. The force analysis of the wire passing wheel 36 is shown in fig. 14. The external force applied to the wire guide wheel 36 includes the tension T of the strand 200 and the supporting force F of the wire guide wheel bracket 34. The supporting force F of the wire wheel bracket 34 to the wire wheel 36 can be decomposed into a vertical component F_yAnd a horizontal component F_x。

Accordingly, force F 'of wire wheel 36 against wire wheel support 34 may also be decomposed into a vertical component F'_yAnd a horizontal component F'_x. Wherein, the horizontal component is F'_xIs equal to the horizontal component F_xThe numerical value of (c). Since the predetermined direction coincides with the horizontal direction and the wire wheel carrier 34 is movably provided in the mounting cavity 311 in the predetermined direction, the value of the force applied to the second pressure sensor 33 by the wire wheel carrier 34 is equal to the horizontal component F'_xNumerical value and horizontal component F of_xThe numerical value of (c). That is, the value measured by the second pressure sensor 33 is the horizontal component F_xThe numerical value of (c).

Thus, the tension T of the strand 200 can be calculated as

T-tension of strand 200 (unit: N); f_xThe measured value of the second pressure sensor 33 (unit: N); alpha-the angle (unit: rad) between the strand 200 and the axial direction of the main shaft 21, i.e. alpha is between the yarn wheel 36 and the distribution board 24, the strands 200 between them are angled from the horizontal.

According to the steel wire rope forming machine 100 and the strand tension detecting device 3 of the embodiment of the invention, the wire wheel support 34 is movably arranged in the mounting cavity 311 of the strand tension detecting device 3 along the axial direction (horizontal direction) of the main shaft 21, and the wire wheel support 34 abuts against the second pressure sensor 33, so that the horizontal component F of the supporting force F of the wire wheel support 34 on the wire wheel 36 can be measured by the second pressure sensor 33_xAnd thus the tension T of the strand 200.

Moreover, by arranging the wire guide wheel bracket 34 movably in the axial direction of the main shaft 21 in the mounting cavity 311 of the strand tension detecting device 3, it is possible to avoid that the measured values of the second pressure sensor 33 are affected by the weight of the wire guide wheel 36 and the wire guide wheel bracket 34, i.e., the measured values of the second pressure sensor 33 do not include the weight of the wire guide wheel 36 and the wire guide wheel bracket 34. This makes it possible to obtain the value measured by the second pressure sensor 33 as the horizontal component F_xSo that the measurement accuracy of the second pressure sensor 33 and the strand tension detecting device 3 can be improved.

Therefore, by using the strand tension detecting device 3 according to the embodiment of the present invention, the tension T of the strand 200 can be accurately measured. The tension T of each strand 200 can thus be controlled by the wire frame 1 based on the tension T of the strand 200 measured by the strand tension detecting device 3 so as to keep the tension T of each strand 200 uniform, so that the quality of the wire rope can be improved.

According to the wire rope cabling machine 100 provided by the embodiment of the invention, by arranging the strand tension detection device 3, when the strand tension detection device 3 detects that the tension of a certain strand 200 is insufficient, the wire frame 1 corresponding to the strand 200 drives the corresponding driving piece 16, so that the rotation speed of the driving piece 16 is reduced when the strand 200 is in a paying-off state, the rotation speed of the second synchronous pulley 14 and the first synchronous pulley 13 is reduced, the rotation speed of the wire wheel 12 is reduced, the paying-off speed of the strand 200 is reduced, and the tension of the strand 200 is increased when the strand 200 is subjected to forward tension. As shown in fig. 1, the state of paying out the strand 200 is such that the pulley 12 rotates counterclockwise. The wire take-up state of the strand 200 is a clockwise rotation of the wire reel 12.

By providing each strand 200 on the wire rope cabling machine 100 with the corresponding strand tension detection device 3 and the wire frame 1, the wire rope cabling machine 100 according to the embodiment of the present invention can detect and control the tension T of each strand 200 so as to finally keep the tension T of each strand 200 consistent, and thus can improve the quality of the wire rope.

As shown in fig. 7 to 13, the strand tension detecting device 3 includes a second body 31, a gland 32, a second pressure sensor 33, a wire wheel bracket 34, a pretensioner 35, and a wire wheel 36.

The second body 31 is provided on an end surface of the front large disc 223 away from the middle large disc 222. For example, the second body 31 is provided on the front end surface (front surface) of the front large disk 223. Specifically, the second body 31 may be detachably mounted on the front large plate 223 by a first bolt 371.

As shown in fig. 11, the second body 31 includes a base 312 and a mount 314. The base 312 has a through hole 313 penetrating the base 312 in the predetermined direction. This facilitates not only the machining of the through hole 313 but also the mounting of the second pressure sensor 33 in the mounting cavity 311. Alternatively, the base 312 may be detachably mounted on the front large plate 223 by a first bolt 371.

The mounting seat 314 is disposed in the through hole 313, and the mounting cavity 311 is defined between the base 312, the mounting seat 314 and the gland 32. Alternatively, as shown in fig. 7, the mount 314 may be detachably mounted on the wall surface of the through hole 313 by a second bolt 372. The mount 314 has a mounting groove in which a portion of the second pressure sensor 33 is disposed. Alternatively, the second pressure sensor 33 may be detachably mounted on the mount 314 by a fourth bolt.

As shown in fig. 7, 9 and 11, the gland 32 is provided on the second body 31. The gland 32 includes a cover plate 321 and a skirt plate 322, the skirt plate 322 being connected to the cover plate 321. The cover 321 is opposite to the second body 31 in the predetermined direction, and the surrounding plate 322 is disposed around the second body 31. Specifically, the cover 321 is opposite to the base 312 in the predetermined direction, and the enclosure 322 is disposed around the base 312.

The shroud 322 is provided on the second body 31. Optionally, a shroud 322 is provided on the base 312. For example, as shown in fig. 7-9, the shroud 322 may be removably mounted to the base 312 by a third bolt 373.

The second pressure sensor 33 is disposed in the mounting cavity 311, and the wire wheel bracket 34 is movably disposed in the mounting cavity 311 along the predetermined direction. As shown in fig. 11, the wire wheel bracket 34 includes a pressing plate 341, a first mounting plate 342, and a second mounting plate 343. The pressing plate 341 abuts on the second pressure sensor 33. A first mounting plate 342 and a second mounting plate 343 are provided on the pressing plate 341 in a spaced-apart relationship, and a wire passing wheel 36 is rotatably provided on each of the first mounting plate 342 and the second mounting plate 343. Thereby making the structure of the wire wheel bracket 34 more reasonable. Optionally, the pressure plate 341 rests on a raised indenter of the second pressure sensor 33.

Optionally, the wire wheel bracket 34 is in clearance fit with the mounting cavity 311. The sheave bracket 34 can thereby be made to freely slide in the mounting cavity 311, so that it is possible to avoid the friction between the sheave bracket 34 and the wall surface of the mounting cavity 311 from affecting the measurement value of the second pressure sensor 33, so as to further improve the measurement accuracy of the second pressure sensor 33 and the strand tension detecting device 3.

As shown in fig. 7, 8, 9 and 11, the preload member 35 is provided on the gland 32. Optionally, the preload member 35 is provided on the cover 321. The preload member 35 is engaged with the thread wheel bracket 34 so that the thread wheel bracket 34 abuts on the second pressure sensor 33. Specifically, when the wire wheel bracket 34 is moved to a position farthest from the second pressure sensor 33, the wire wheel bracket 34 abuts not only on the second pressure sensor 33 but also on the preload member 35 as well as the wire wheel bracket 34. When the wire passing wheel bracket 34 is moved to a position nearest to the second pressure sensor 33, the wire passing wheel bracket 34 abuts on the second pressure sensor 33, and the wire passing wheel bracket 34 can be disengaged from the preload member 35.

Therefore, the wire wheel support 34 can always abut against the second pressure sensor 33, so that the measurement accuracy of the second pressure sensor 33 can be further improved, and the measurement range of the second pressure sensor 33 can be expanded.

As shown in fig. 11, the preload member 35 includes a bolt 351 and a spring washer 352. The bolt 351 includes a nut 3511 and a threaded rod 3512 coupled to the nut 3511, the threaded rod 3512 being threadably engaged with the gland 32. The free end of the screw 3512 passes through the gland 32, and the free end of the screw 3512 is pressed against the upper surface of the wire wheel bracket 34. The spring washer 352 is sleeved on the screw 3512, the nut 152 is located between the nut 1511 and the gland 12, and the nut 152 is pressed on the upper surface of the gland 12 to play a role in fixing the bolt 151. . This makes the structure of the preload member 35 more rational.

Specifically, when the thread wheel bracket 34 is moved to a position farthest from the second pressure sensor 33, the thread wheel bracket 34 abuts on the free end of the screw 3512. When the wire-wheel support 34 is moved to a position nearest to the second pressure sensor 33, the wire-wheel support 34 may be disengaged from the free end of the screw 3512.

As shown in fig. 7, 9 and 11, the preload members 35 are two in number, one preload member 35 engaging the first mounting plate 342 and the other preload member 35 engaging the second mounting plate 343. That is, when the wire wheel bracket 34 is moved to a position farthest from the second pressure sensor 33, the first mounting plate 342 abuts on the free end of the screw 3512 of the one preload member 35, and the second mounting plate 343 abuts on the free end of the screw 3512 of the other preload member 35. When the wire wheel bracket 34 is moved to a position nearest to the second pressure sensor 33, the first mounting plate 342 is disengaged from the free end of the threaded rod 3512 of the one preload member 35, and the second mounting plate 343 is disengaged from the free end of the threaded rod 3512 of the other preload member 35.

The wire passing wheel 36 is rotatably provided on the wire passing wheel bracket 34. As shown in fig. 8, 9, 12 and 13, the second body 31 has a first relief hole, and the pressing cover 32 has a second relief hole. The first portion 361 of the wire passing wheel 36 passes through the first escape hole so as to be located outside the mounting cavity 311, and the second portion 362 of the wire passing wheel 36 passes through the second escape hole so as to be located outside the mounting cavity 311. That is, the first portion 361 of the wire guide wheel 36 protrudes to the outside of the mounting cavity 311 through the first escape hole, and the second portion 362 of the wire guide wheel 36 protrudes to the outside of the mounting cavity 311 through the second escape hole. The structure of the strand tension detecting device 3 can thereby be made more rational.

As shown in fig. 10 and 11, the thread guide wheel 36 is rotatably provided on the thread guide wheel support 34 by a wheel shaft 38, and an axial direction of the wheel shaft 38 is perpendicular to the preset direction. Whereby the wire passing wheel 36 can also move in the preset direction. Alternatively, the axial direction of the hub 38 may coincide with the horizontal direction (second horizontal direction). The second horizontal direction may be perpendicular to the first horizontal direction.

As shown in fig. 11, the shroud plate 322 has a third avoidance hole 3221 and a fourth avoidance hole 3222, and the third avoidance hole 3221 and the fourth avoidance hole 3222 are opposite to each other in the axial direction of the axle 38. Wherein each of the third and

fourth avoidance holes

3221 and 3222 passes through the shroud 322 in the axial direction of the axle 38. Therefore, the wheel axle 38 can be installed through the third avoiding hole 3221 and the fourth avoiding hole 3222, and the installation difficulty of the wheel axle 38 can be reduced.

As shown in fig. 10 and 11, the axle 38 has a positioning shoulder 381, and the strand tension detecting device 3 further comprises a positioning sleeve 391, a positioning nut 392, a first bearing 393 and a second bearing 394. The positioning sleeve 391 is sleeved on the wheel shaft 38, and the wire passing wheel bracket 34 is clamped between the positioning shoulder 381 and the positioning sleeve 391. In other words, the wire guide wheel bracket 34 is located between the positioning shoulder 381 and the positioning sleeve 391 in the axial direction of the wheel shaft 38, and both the positioning shoulder 381 and the positioning sleeve 391 abut against the wire guide wheel bracket 34.

The positioning nut 392 is threaded onto the axle 38, i.e., the axle 38 has a threaded section onto which the positioning nut 392 is threaded. The positioning nut 392 abuts against the positioning sleeve 391. Whereby the axle 38 can be positioned in the axial direction of the axle 38. First and

second bearings

393 and 394 are provided on the wire wheel 36, and the wheel shaft 38 is supported on the first and

second bearings

393 and 394.
