Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1-8, an embodiment of the present invention provides a cable laying assist apparatus that may include a base plate 1, a bracket 2, a winding roller 3, an intermittent rotation assembly 4, and a rotary motion follower 5. Wherein:

the brackets 2 are fixed on the bottom plate 1, the brackets 2 are used for fixing other elements of the device, and a person skilled in the art can determine the number and the shape of the brackets 2 according to actual needs, which is not limited herein. The winding roller 3 is rotatably connected with the bracket 2, and the rotating shaft of the winding roller 3 is horizontally arranged (the horizontal arrangement means that the axis of the rotating shaft is positioned on the horizontal plane) so as to horizontally wind the cable. The intermittent rotating assembly 4 is positioned on the bracket 2 and is connected with the central shaft of the winding roller 3. The rotary motion output device 5 is installed on the support 2 and is in transmission connection with the intermittent rotating assembly 4 so as to drive the intermittent rotating assembly 4 to drive the winding rollers 3 to rotate in a clearance mode to unwind and wind the cable. Therefore, the winding roller 3 can be used for winding the cable intermittently and rapidly, the neatness of the cable in the arranging process can be guaranteed, and the wiring efficiency is improved.

In an embodiment, the rotational output device 5 may include, but is not limited to, a motor, a combination structure of a motor and other transmission units, and the like. For example, when the rotational motion follower 5 is a motor, the apparatus may further include a battery module. The battery module may include a battery, an electronic control unit, and a wireless communication unit. Wherein the battery supplies power to the rotational motion follower 5, the electronic control unit and the wireless communication unit simultaneously, the electronic control unit being coupled to the wireless communication unit and to the rotational motion follower 5. For example, a battery may be fixedly connected to the body 1 and a wireless communication unit may be used to establish a wireless connection with a user terminal. By means of the wireless communication unit, the user can send control signals to the electronic control unit based on the user terminal to adjust the rotational speed of the rotary motion follower 5 by means of the electronic control unit. Thereby achieving control of the speed at which the wire is unwound by the winding roller 3.

An alternative embodiment of the invention, as shown in fig. 1, fig. 2, fig. 4 and fig. 6, the intermittent rotation assembly 4 may include a first rotation shaft 401, a ratchet mechanism 402, a rectangular frame 403, a second rotation shaft 404, a third rotation shaft 405 and a crank 406, wherein:

the first rotating shaft 401 is rotatably connected to the bracket 2, and the ratchet mechanism 402 is located between the first rotating shaft 401 and the winding roller 3, wherein the ratchet mechanism 402 is connected to the side of the winding roller 3 and the end of the first rotating shaft 401. When the first rotating shaft 401 rotates, the ratchet mechanism 402 is driven to move, so that the winding roller 3 is driven to rotate by the ratchet mechanism 402. The rectangular frame 403 is sleeved on the first rotating shaft 401 and movably connected with the first rotating shaft 401. The movable connection can be understood as that the relative position between the rectangular frame 403 and the first rotating shaft 401 changes under the external force.

The second rotating shaft 404 penetrates through the rectangular frame 403 and the first rotating shaft 401 at the same time, and forms a rotating connection with the first rotating shaft 401. For example, the second rotating shaft 404 may penetrate the rectangular frame 403 and the first rotating shaft 401 from the vertical direction. Wherein, the axis of the first rotating shaft 401 and the axis of the second rotating shaft 404 form an intersection point. That is, the first rotating shaft 401 and the second rotating shaft 404 form a cross therebetween, for example, when the second rotating shaft 404 vertically penetrates, the first rotating shaft 401 and the second rotating shaft 404 are disposed perpendicular to each other.

The third rotating shaft 405 is rotatably connected with the rectangular frame 403, and an axis of the third rotating shaft 405 is parallel to a length direction of the rectangular frame 403. Wherein, the length direction of the rectangular frame 403 is the same as the horizontal direction. One end of the crank 406 is fixedly connected to the output shaft of the rotational motion output device 5, and the other end is fixedly connected to the end of the third rotating shaft 405 far from the rectangular frame 403. Wherein the intersection coincides with an axis extension of the output shaft of the rotational movement follower 5. Therefore, when the rotational motion follower 5 works, the crank 406 can be driven to rotate to drive the rectangular frame 403 to swing up and down and simultaneously rotate around the second rotating shaft 404, and when the rectangular frame 403 swings up and down, the first rotating shaft 401 can be driven to rotate around the axis of the second rotating shaft 404 due to the limiting effect of the second rotating shaft 404. And the rotation track is a reciprocating rotation motion in the forward and reverse directions.

In one example, when the crank 406 moves to the lowest point, the rectangular frame 403 is perpendicular to the axis of the first rotating shaft 401, and the end of the rectangular frame 403 close to the third rotating shaft 405 is at the lowest point. The lowest point may be understood as the point at which the vertical height is at its lowest. When the crank 406 moves to the highest point, the rectangular frame 403 is perpendicular to the axis of the first rotating shaft 401, and the end of the rectangular frame 403 close to the third rotating shaft 405 is at the highest point. The highest point is understood to be the point where the vertical height is at the highest.

When the crank 406 rotates along with the rotary motion follower 5, the rectangular frame 403 rotates around the axis of the second rotating shaft 404 by a certain angle, and the angle between the rectangular frame 403 and the first rotating shaft 401 also changes. Thereby realizing the up-down swing and the left-right swing of the rectangular frame 403.

An alternative embodiment of the invention is shown in fig. 1, fig. 2, fig. 4 and fig. 5, the ratchet mechanism 402 may include a transmission ratchet 4021, a first elastic sheet 4022, a shift lever 4023, a driving lever 4024 and a second elastic sheet 4025, where:

the transmission ratchet 4021 is coaxially fixed with the side of the winding roller 3. Coaxial fixation means that the axis of the drive ratchet 4021 coincides with the axis of the winding roller 3. The first elastic sheet 4022 is fixed on the support 2 and is engaged with the transmission ratchet 4021. The first elastic sheet 4022 is engaged with the transmission ratchet 4021, so that the rotational stability of the transmission ratchet 4021 can be improved. The first resilient piece 4022 may be located right below the transmission ratchet 4021. Provided with gear teeth which come into engagement with said drive ratchet 4021.

The shift lever 4023 is fixed to the first rotating shaft 401 and extends in a radial direction of the first rotating shaft 401. The driving rod 4024 is rotatably connected to the shift lever 4023 and contacts with the gear teeth of the transmission ratchet 4021. The second elastic piece 4025 is located on the shift lever 4023, and presses the driving lever 4024 to the transmission ratchet 4021. The second resilient plate 4025 is always in a pressed state, that is, one end of the second resilient plate 4025 is fixed to the shift lever 4023, and the other end of the second resilient plate 4025 is in pressed contact with the driving rod 4024. Therefore, the second elastic sheet 4025 generates a pressing force for pressing the driving rod 4024 to the transmission ratchet 4021. When the first rotating shaft 401 rotates forward and backward, the shifting lever 4023 is driven to be inserted into the gear teeth of the transmission ratchet 4021, so that the transmission ratchet 4021 rotates by a certain angle.

In an embodiment, when the direction shown in fig. 5 is taken as a reference direction, when the driving rod 4024 swings clockwise, the driving rod 4024 passes through the transmission ratchet 4021, and the transmission ratchet 4021 does not rotate. When the driving rod 4024 swings counterclockwise, the driving rod 4024 is inserted into the gear teeth of the transmission ratchet 4021, and the transmission ratchet 4021 is pushed to rotate in the same direction. Thus, the winding roller 3 can be driven to rotate by a certain angle and rotate in one direction when the rotary motion follower 5 rotates for one circle. Therefore, the low-speed unwinding of the winding roller 3 can be realized through the high-speed rotating motion follower 5 so as to adapt to the winding efficiency in practical application scenes.

An alternative embodiment of the invention, as shown in fig. 1 and 2, the apparatus may further include a wire conduit 6, and the wire conduit 6 is fixed on the bracket 2, wherein an end of the wire conduit 6 close to the winding roller 3 faces a tangential direction of the circumferential surface of the winding roller 3, and an end of the wire conduit 6 far away from the winding roller 3 faces parallel to an axial direction of the winding roller 3, so as to guide the wire, and further facilitate the unwinding of the wire on the winding roller 3.

An alternative inventive embodiment, as shown in fig. 1, 2, 4 and 6, the apparatus may further include a cable driving assembly 7, and the cable driving assembly 7 may include a fourth rotating shaft 701, a universal ball 702, a ball seat 703, a first guide rail 704, a sliding plate 705, a second guide rail 706, a fixing plate 707 and a rotating clamping mechanism 708, wherein:

the fourth rotating shaft 701 is fixed to an end portion of the rectangular frame 403 far away from the third rotating shaft 405, and an axis of the fourth rotating shaft 701 is parallel to a length direction of the rectangular frame 403. The universal ball 702 is fixed on the end of the fourth rotating shaft 701 far away from the rectangular frame 403. The ball seat 703 is sleeved on the outer surface of the universal ball 702 and is movably connected with the universal ball 702. The first guide rail 704 is provided with a first sliding groove 7041, and the ball seat 703 is located in the first sliding groove 7041 and is slidably connected to the first guide rail 704. The first sliding groove 7041 may be a linear groove that is formed along the longitudinal direction of the first guide rail 704. The slide 705 is fixedly connected to the first guide 704. Accordingly, when the rectangular frame 403 swings up and down, the ball seat 703 can be driven to slide up and down along the first guide rail 704. The sliding direction of the ball seat 703 coincides with the swinging direction of the end of the rectangular frame 403 close to the fourth rotating shaft 701.

The second guide rail 706 is fixed on the base plate 1, wherein the sliding plate 705 is slidably connected to the second guide rail 706, and a sliding direction of the sliding plate 705 on the second guide rail 706 is parallel to an axial direction of the first rotating shaft 401. The fixing plate 707 is located on the end of the sliding plate 705 away from the first guide rail 704 and is vertically placed. The vertical placement is understood to mean that the plane of the fixed plate 707 with the largest surface area is parallel to the vertical. Accordingly, when the rectangular frame 403 swings left and right, the slide plate 705 can be driven to slide left and right on the second guide rail 706. The sliding direction of the sliding plate 705 coincides with the swinging direction of the end of the rectangular frame 403 close to the fourth rotating shaft 701.

The rotating clamping mechanism 708 is mounted on the fixing plate 707 and faces the end of the conduit 6 away from the winding roller 3 to clamp the cable. Wherein the rotary clamping mechanism 708 is in driving connection with the rotary motion output 5 to provide a clamping force via the rotary motion output 5. Therefore, when the rotary motion follower 5 drives the winding roller 3 to unwind the cable, the cable can be synchronously clamped, so that the effects of carding the cable and guiding the cable can be achieved, and the cable wiring efficiency can be further improved.

An alternative inventive embodiment, as shown in fig. 6 and 8, the rotary clamping mechanism 708 may include a circular disk 7081, a first pin 7082, a third guide rail 7083, an elongated bar 7084, a second pin 7085, a guide bar 7086, a fourth guide rail 7087, a rack and pinion transmission unit 7088, and a plurality of clamping portions 7089, wherein:

the disk 7081 is fixed coaxially with the output shaft of the rotational motion follower 5. Coaxial fastening is to be understood as fastening the disk 7081 to the output shaft of the rotary motion output means 5, in the case of an axis of the disk 7081 coinciding with the axis of the output shaft of the rotary motion output means 5. A closed cam groove 70811 is provided at the end of the disc 7081 remote from the third axis of rotation 405. The first pin 7082 is positioned in the cam slot 70811 and is slidably coupled to the disk 7081. Wherein the cam groove 70811 may be understood as a groove in the shape of a cam. The cam groove 70811 surrounds the output shaft of the rotary motion output device 5, so that the first pin 7082 can be driven into a rotary motion in the cam groove 70811 during operation of the rotary motion output device 5.

The third guide rail 7083 is fixed to the support frame 2, and the long bar 7084 is horizontally disposed. Wherein, horizontally disposed is understood to mean that the length of the elongated bar 7084 is parallel to the horizontal. And the two ends of the elongated bar 7084 are slidably connected within the third guide rail 7083. The end of the first pin 7082 remote from the cam slot 70811 is fixed to the middle of the elongated bar 7084. Wherein the sliding direction of the elongated bar 7084 is parallel to the end of the crank 406 near the rotary motion follower 5. A long bar hole 70841 is further formed along the length direction of the long bar 7084, and one end of the second pin 7085 is located in the long bar hole 70841 and is slidably connected to the long bar 7084. The length of the elongated hole 70841 is greater than the stroke of the slide plate 705 in reciprocating motion. So that the second pin 7085 does not interfere with the elongated bar 7084 during reciprocation of the fixed plate 707 with the slide 705.

One end of the guide rod 7086 is fixedly connected to the other end of the second pin 7085. Wherein, a plurality of gear teeth are arranged on the guide bar 7086. The fourth guide rail 7087 is fixed to the fixing plate 707, and the guide rod 7086 is embedded in the fourth guide rail 7087 and slidably connected to the fourth guide rail 7087. The rack and pinion gear unit 7088 is located on the fixed plate 707 and is engaged with the gear teeth of the guide bar 7086. The plurality of clamping portions 7089 are connected with the rack and pinion transmission unit 7088 so as to control the clamping portions 7089 to act through the rack and pinion transmission unit 7088. When the rotary motion follower 5 is operated, the plurality of gripping portions 7089 are driven to make intermittent contact with the outer surface of the cable, thereby clamping the cable. And pulls the cable when the fixing plate 707 reciprocates. Therefore, the carding before the cable is unwound by the winding roller 3 can be realized, and the working efficiency is further improved.

In an alternative embodiment of the invention, the number of the clamping portions 7089 is three, and the rack and pinion gear unit 7088 may include two fifth guide rails 70881, two transmission gears 70882, and two transmission racks 70883, wherein:

the two fifth guide rails 70881 are symmetrically disposed with respect to the fourth guide rail 7087. The two transmission gears 70882 are rotatably connected to the fixing plate 707, are distributed on two sides of the guide rod 7086, and are engaged with the gear teeth of the guide rod 7086. The two transmission racks 70883 are respectively connected in the two fifth guide rails 70881 in a sliding manner, and the two transmission racks 70883 and the guide rods 7086 are arranged in a crossed manner. Wherein, two driving gears 70882 and two driving racks 70883 are respectively engaged to drive the driving racks 70883 to slide on the fifth guide rail 70881 by the sliding of the guide rods 7086, and the ends of the two driving racks 70883, which are close to each other, are provided with bending parts. The end part of the guide rod 7086 far away from the second pin 7085 and the two bent parts respectively fix one clamping part 7089.

In one example, when the first pin 7082 moves to a position within the cam slot 70811 where the distance from the center of the disk 7081 is a minimum, the elongated bar 7084 slides along the third guide rail 7083 to a position closest to the output shaft of the rotary motion follower 5. When the first pin 7082 moves to a position within the cam slot 70811 that is a maximum distance from the center of the disk 7081, the elongated bar 7084 slides along the third guide rail 7083 to a position that is furthest from the output shaft. Thereby achieving the reciprocating motion of the long bar 7084 along the third guide rail 7083. Meanwhile, the second pin 7085 on the second elongated bar 7084 drives the guide bar 7086 to reciprocate along the fourth guide rail 7087. Thus, the gripping portion 7089 grips the outer surface of the cable as the guide bar 7086 is moved away from the output shaft. And synchronously drives the transmission gear 70882 to rotate through a guide rod 7086. So that the driving rack 70883 slides along the fifth guide rail 70881 and, through the bent portion, brings the other two clamping portions 7089 to clamp the outer surface of the cable.

In an alternative embodiment of the invention, the cross-sectional shape of the clamping portion 7089 is an arc. The arc-shaped design can increase the contact area with the cable, and the clamping degree is ensured while the outer surface of the cable is not damaged. In one embodiment, the axis of the clamping portion 7089 coincides with the axis of the end of the conduit 6 remote from the winding roller 3. This improves the efficiency of pulling the cable when the fixing plate 707 reciprocates.

In an alternative embodiment of the invention, the holding portion 7089 is made of rubber or latex material. Thereby guarantee the clamping part 7089 can be with the cable fully fixed and can not be to under the clamping state the cable causes the damage, and then conveniently realizes pulling of cable.
