Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and more specifically, to a cable laying device. Background Technology

[0002] During the cable laying process, cable laying is an important step. The existing cable laying method mainly involves manually pushing a cable trolley, which carries a cable reel. The cable is laid out by rotating the reel as it moves along the trolley.

[0003] However, because the travel speed changes constantly, and the cable laying speed requires constant manual observation and control, cable drops frequently occur due to improper operation. This causes the cable to rub against the ground and trench, resulting in abrasions. In particular, during the process of the cable entering the cable trench, the cable laying speed often deviates significantly from the vehicle's movement speed. When the laying speed is less than the equipment's travel speed, the cable frequently rubs against the ground and trench walls, directly causing damage, perforation, and twisting of the cable insulation layer. This reduces the insulation performance of the cable insulation layer, allows water to enter and become damp, and in severe cases, renders the cable unusable. If the laying speed is too fast, the cable may twist, requiring a single person to constantly follow and adjust, making the operation even more complicated. Summary of the Invention

[0026] According to the technical solution of this invention, the wire feeding device includes a vehicle body, a traveling mechanism, a transmission assembly, and a turntable. A wire spool is mounted on the vehicle body, and a cable is wound on the wire spool. The traveling mechanism is mounted on the vehicle body and includes a traveling frame, which is rotatably mounted around a first axis to drive the vehicle body to move. One end of the transmission assembly is connected to the traveling frame, and the other end of the transmission assembly is connected to the turntable, so that during the rotation of the traveling frame, the transmission assembly drives the turntable to rotate around a second axis, which is perpendicular to the first axis. There are two sets of transmission assemblies, which are spaced apart along the axial direction of the traveling frame. There are two turntables, which are respectively connected to the two sets of transmission assemblies. A through-gap is provided between the first circumferential sides of the two turntables for the cable to pass through. The two turntables rotate in opposite directions so that the cable is squeezed out of the through-gap during the rotation of the two turntables. This configuration allows two sets of transmission components to drive two turntables to rotate during the movement of the vehicle body by the traveling frame. This forces the cable through the gap. The rotation speed of the turntable is directly proportional to the cable feeding speed, and the turntable's rotation speed is related to the traveling frame. In other words, the cable feeding speed is linked to the vehicle body's moving speed. As the vehicle body moves, the cable feeding speed is automatically adjusted according to the changes in the vehicle body's moving speed, eliminating the need for manual control of the cable feeding speed. This avoids large deviations between the vehicle body's traveling speed and the cable feeding speed, which could lead to cable wear or cable tangling. Attached Figure Description

Detailed Implementation

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Please refer to Figures 1 to 12This invention provides a wire feeding device, comprising: a vehicle body 100, on which a wire spool 110 is disposed, and a cable 120 is wound on the wire spool 110; a traveling mechanism 200 disposed on the vehicle body 100, the traveling mechanism 200 including a traveling frame 210 rotatably disposed about a first axis to drive the vehicle body 100 to move; a transmission assembly 300; and a turntable 400, one end of the transmission assembly 300 being connected to the traveling frame 210, and the other end of the transmission assembly 300 being connected to the turntable 400, so that during the rotation of the traveling frame 210, the cable 120 is moved via the transmission assembly 300. 00 drives the turntable 400 to rotate around the second axis, which is perpendicular to the first axis; wherein, there are two sets of transmission components 300, which are spaced apart along the axis of the walking frame 210; there are two turntables 400, which are respectively connected to the two sets of transmission components 300; a through gap 402 for the cable 120 to pass through is provided between the first circumferential side 401 of the two turntables 400; the two turntables 400 rotate in opposite directions, so that the cable 120 is squeezed out from the through gap 402 during the rotation of the two turntables 400.

[0050] The wire feeding device provided by the present invention includes a vehicle body 100, a traveling mechanism 200, a transmission assembly 300, and a turntable 400. A wire spool 110 is disposed on the vehicle body 100, and a cable 120 is wound on the wire spool 110. The traveling mechanism 200 is disposed on the vehicle body 100 and includes a traveling frame 210, which is rotatably disposed about a first axis to drive the vehicle body 100 to move. One end of the transmission assembly 300 is connected to the traveling frame 210, and the other end of the transmission assembly 300 is connected to the turntable 400, so that during the rotation of the traveling frame 210, the cable spool 120 is moved via the transmission assembly 400. The component 300 drives the turntable 400 to rotate around the second axis, which is perpendicular to the first axis. There are two sets of transmission components 300, which are spaced apart along the axis of the walking frame 210. There are two turntables 400, which are respectively connected to the two sets of transmission components 300. A through gap 402 for the cable 120 to pass through is provided between the first circumferential side 401 of the two turntables 400. The two turntables 400 rotate in opposite directions so that the cable 120 is squeezed out from the through gap 402 during the rotation of the two turntables 400. This configuration allows the two sets of transmission components 300 to drive the two turntables 400 to rotate during the movement of the vehicle body 100 driven by the traveling frame 210. This enables the cable 120 to be squeezed out from the through gap 402. At this time, the rotation speed of the turntable 400 is proportional to the cable feeding speed, and the rotation speed of the turntable 400 is related to the traveling frame 210. That is, the cable feeding speed is linked to the moving speed of the vehicle body 100. Thus, during the movement of the vehicle body 100, the cable feeding speed is automatically adjusted according to the change in the moving speed of the vehicle body 100. There is no need for manual control of the cable feeding speed, which avoids a large deviation between the traveling speed of the vehicle body 100 and the cable feeding speed, thereby preventing wear on the cable 120 or the cable 120 from becoming tangled or coiled.

[0051] Specifically, such as Figures 4 to 9 As shown, each transmission assembly 300 includes: a first bevel gear 310, sleeved on the traveling frame 210, which drives the first bevel gear 310 to rotate; and a second bevel gear 311, meshing with the first bevel gear 310, which drives the second bevel gear 311 to rotate around a second axis. The second bevel gear 311 is connected to the turntable 400 to drive the turntable 400 to rotate. By meshing the first bevel gear 310 and the second bevel gear 311, the horizontal rotation of the traveling frame 210 is converted into vertical rotation, thereby achieving the purpose of transmitting power to the turntable 400 and driving the turntable 400 to rotate during the movement of the vehicle body 100.

[0052] Furthermore, such as Figure 8 and Figure 9As shown, each transmission assembly 300 further includes: a drive rod 320, a second bevel gear 311 connected to the drive rod 320, which drives the drive rod 320 to rotate around the second axis through the second bevel gear 311, and a turntable 400 sleeved on the drive rod 320; the drive rod 320 is provided with a plurality of first slots 321, which are spaced apart along the circumferential direction of the drive rod 320, and each first slot 321 extends along the axial direction of the drive rod 320; the inner sidewall 403 of the turntable 400 is provided with a plurality of first protrusions 404, which extend along the axial direction of the turntable 400, and each first protrusion 404 is engaged in each first slot 321. The drive rod 320 extends vertically and has a shaft structure. A second bevel gear 311 is connected to the bottom end of the drive rod 320. The turntable 400 is connected to the drive rod 320 by engaging with the first slots 321 through the first protrusions 404. During the rotation of the drive rod 320, the turntable 400 is driven to rotate by the mutual stopping action between the first protrusions 404 and the first slots 321. Furthermore, the bevel tooth surfaces of the two second bevel gears 311 in each transmission assembly 300 are arranged opposite each other. Thus, during the rotation of the two first bevel gears 310, the two second bevel gears 311 rotate in different directions, thereby causing the two drive rods 320 to drive the two turntables 400 to rotate in opposite directions.

[0053] In the specific implementation process, such as Figure 4 As shown, the walking frame 210 is located below the vehicle body 100. A first through-passage 131 is provided on the bottom plate 130 of the vehicle body 100. A first slide groove 132 is provided on the channel wall of the first through-passage 131. The extending direction of the first slide groove 132 is consistent with the extending direction of the walking frame 210. Each set of transmission components 300 also includes: a first mounting base 330, at least a portion of which is disposed in the first through-passage 131. A drive rod 320 passes through the first mounting base 330 and is connected to the turntable 400. The drive rod 320 is rotatably disposed relative to the first mounting base 330. A first insert 331 is disposed on the first mounting base 330. At least a portion of the first insert 331 is inserted into the first slide groove 132 and is movably disposed along the extending direction of the first slide groove 132. A second bearing 350 is provided between the drive rod 320 and the first mounting base 330. The drive rod 320 rotates relative to the first mounting base 330 through the second bearing 350. At the same time, when the first mounting base 330 moves in the horizontal direction, the drive rod 320 can drive the turntable 400 to move synchronously, thereby adjusting the horizontal distance between the two turntables 400, that is, adjusting the size of the through gap 402 to accommodate cables 120 of different diameters. It can also adaptively adjust the transmission distance between the two turntables 400.

[0054] In this application, the wire-laying device also includes a telescopic component 500, at least partially telescopically configured. Both ends of the telescopic component 500 are respectively connected to two first mounting seats 330 in two sets of transmission assemblies 300, so that the two first mounting seats 330 move closer or further apart during the telescopic component 500's extension and retraction. By pushing and pulling the two first mounting seats 330 using the telescopic component 500, the distance between the two first mounting seats 330 is adjusted, ultimately adjusting the distance between the two turntables 400.

[0055] Specifically, the telescopic component 500 includes: a sleeve 510 with an internal thread; a first threaded rod 520, one end of which is threaded to the first end of the sleeve 510, and the other end of which is connected to one of the two first mounting seats 330; and a second threaded rod 530, one end of which is threaded to the second end of the sleeve 510, and the other end of which is connected to the other of the two first mounting seats 330. This structure is simple and easy to operate. The thread direction of the first threaded rod 520 is opposite to that of the second threaded rod 530. By rotating the sleeve 510, the first threaded rod 520 and the second threaded rod 530 can be extended or retracted under the action of the threaded engagement, thereby driving the two first mounting seats 330 to move.

[0056] To enable the first mounting base 330 and the first bevel gear 310 to move synchronously, each transmission assembly 300 further includes: a first connecting plate 340, which has a first through hole 341. The first connecting plate 340 is sleeved on the traveling frame 210 through the first through hole 341, and is connected to the first bevel gear 310 and the first mounting base 330 respectively. The first connecting plate 340 also has a third protrusion 342, which surrounds the first through hole 341 and protrudes relative to the surface of the first connecting plate 340. A slot 313 is provided on the end face of the first bevel gear 310 away from the bevel tooth surface. The slot 313 is a recess, and the third protrusion 342 is inserted into the slot 313 with a clearance fit, allowing the first bevel gear 310 to rotate relative to the first connecting plate 340. When the diameter of the cable 120 is large, the two first mounting seats 330 are pushed away from each other. The two first mounting seats 330 drive the two drive rods 320 to move, which in turn causes the second bevel gear 311 to push the first bevel gear 310 to move. When the two first mounting seats 330 approach each other, the first mounting seats 330 drive the drive rods 320 to move, and at the same time, the two first connecting plates 340 push the two first bevel gears 310 to gradually approach each other.

[0057] In the specific implementation process, such as Figures 6 to 8As shown, the wire feeding device also includes: a retainer 610, which is disposed on the vehicle body 100 and located above the transmission assembly 300. The retainer 610 is provided with a second slide groove 611, which extends in a horizontal direction; and a first slider 620, which is disposed at the end of the drive rod 320 and connected to the drive rod 320. The first slider 620 is disposed in the second slide groove 611 and is movably disposed along the extending direction of the second slide groove 611. This configuration ensures the stability of the drive rod 320's movement. The turntable 400 is fitted in the middle of the drive rod 320, and the second bevel gear 311 is connected to the bottom of the drive rod 320. Therefore, in order to keep the drive rod 320 balanced during its movement, a retainer 610 is provided above the transmission assembly 300. The retainer 610 contains a second slide groove 611 and a first slider 620. The top of the drive rod 320 is connected to the first slider 620. Thus, during the movement of the drive rod 320, the first slider 620 moves within the second slide groove 611, keeping the drive rod 320 stable.

[0058] In the embodiments provided in this application, a third slide groove 211 is provided on the walking frame 210, and the third slide groove 211 extends along the axial direction of the walking frame 210; a second insert 312 is provided on the inner wall surface of the first bevel gear 310 in each group of transmission components 300, and the second insert 312 is inserted into the third slide groove 211, and the second insert 312 is movably arranged along the extension direction of the third slide groove 211. The walking frame 210 is a shaft structure, and walking wheels 220 are respectively provided at both ends of the walking frame 210. The walking frame 210 extends from the vehicle body 100 and connects to the walking wheels 220. The walking frame 210 and the vehicle body 100 are connected by a first bearing 221, allowing the walking frame 210 to rotate relative to the vehicle body 100. Furthermore, the second insert 312 extends along the axial direction of the first bevel gear 310. By providing a third slide groove 211 on the traveling frame 210, and with the first bevel gear 310 engaging with the third slide groove 211 through the second insert 312, the second insert 312 guides the first bevel gear 310 when it moves horizontally. Simultaneously, under the mutual blocking action of the second insert 312 and the third slide groove 211, the traveling frame 210 drives the first bevel gear 310 to rotate.

[0059] In this application, the cable laying device further includes a height adjustment mechanism 700, which includes a tray 710. The tray 710 is disposed below and connected to the turntable 400, and is movably disposed vertically to move the turntable 400. Adjusting the height of the turntable 400 via the height adjustment mechanism 700 controls the exit position of the cable 120, facilitating more precise cable laying and improving laying efficiency.

[0060] Specifically, such as Figure 11 and Figure 12 As shown, the height adjustment mechanism 700 further includes: a lifting frame 720, movably arranged in the vertical direction; a support arm 730, one end of which is connected to the lifting frame 720, and the other end of which is connected to the tray 710; and a cable guide slider 733, disposed within the lifting frame 720 and movably arranged along the extension direction of the lifting frame 720. The cable guide slider 733 has a second through-channel 731, through which the cable 120 passes through the through-gap 402 and exits through the second through-channel 731. The lifting frame 720 drives the support arm 730 to move, thereby driving the turntable 400 to move vertically. The second through-channel 731 guides and supports the cable 120, preventing it from drooping under gravity after exiting through the through-gap 402. In addition, since a retainer 610 is provided above the transmission assembly 300, a support arm 730 is provided to avoid interference between the retainer 610 and the height adjustment mechanism 700. The support arm 730 is a strip plate and is used to connect the tray 710 and the lifting frame 720, so that the lifting frame 720 can be set on the side of the turntable 400, thereby adjusting the lifting of the turntable 400.

[0061] Furthermore, the lifting frame 720 is provided with a second through hole 721, which extends along the length of the lifting frame 720. The height adjustment mechanism 700 also includes an adjustment component 740, at least a portion of which passes through the second through hole 721 and connects to the cable slider 733. The adjustment component 740 drives the cable slider 733 to move. Preferably, the adjustment component 740 is an adjustment bolt, which is threadedly engaged with the cable slider 733. The adjustment bolt fits against the body of the lifting frame 720 surrounding the second through hole 721, fixing the cable slider 733 under the action of friction. The cable slider 733 is made movable, and after adjusting the horizontal distance between the two turntables 400, the position of the cable slider 733 corresponds to the through gap 402, thereby facilitating the cable 120 to pass through.

[0062] In specific implementation, the vehicle body 100 is provided with two fourth sliding grooves 140, which are respectively located on two opposite side walls of the vehicle body 100 and extend vertically. The lifting frame 720 has two third inserts 722 at both ends, which are inserted into the two fourth sliding grooves 140 respectively. The third inserts 722 are movably positioned along the extending direction of the fourth sliding grooves 140. This arrangement guides the lifting frame 720 during its lifting process through the interaction between the third inserts 722 and the fourth sliding grooves 140.

[0063] In the embodiments provided in this application, the tray 710 includes: a first supporting body 711, with at least a portion of one of the two turntables 400 disposed on the first supporting body 711; a second connecting plate 712 connected to the first supporting body 711, the second connecting plate 712 having a fifth sliding groove 713, and the second connecting plate 712 being connected to a support arm 730; a second supporting body 714, with at least a portion of the other of the two turntables 400 disposed on the second supporting body 714; and a third connecting plate 715 connected to the second supporting body 714, the third connecting plate 715 having a fourth insert 716 inserted into the fifth sliding groove 713, the fourth insert 716 being movably disposed along the extending direction of the fifth sliding groove 713, so that the first supporting body 711 and the second supporting body 714 move closer to or further away from each other. The support arm 730 has a groove 732 at its end away from the lifting frame 720. The groove 732 is recessed relative to the surface of the support arm 730, and at least a portion of the second connecting plate 712 is engaged in the groove 732. The first supporting body 711 has a fifth through hole 7114, and the second supporting body 714 has a sixth through hole 7144. Two drive rods 320 pass through the fifth and sixth through holes 7114 and 7144 respectively, and are clearance-fitted with them. The first and second supporting bodies 711 and 714 support the two turntables 400. As the two turntables 400 move horizontally, the sliding engagement between the fourth insert 716 and the fifth slide groove 713 allows the first and second supporting bodies 711 and 714 to move horizontally with the two turntables 400, thus preventing obstruction during movement.

[0064] Furthermore, a first baffle 7110 is provided on the first support body 711, extending circumferentially along the first support body 711. A first flange 7111 is provided at the end of the first baffle 7110 away from the first support body 711, folding towards the center of the first support body 711. A second slot 7112 is provided between the first flange 7111 and the first baffle 7110, with at least a portion of one of the two turntables 400 located within the second slot 7112. A second baffle 7140 is provided on the second support body 714, extending circumferentially along the second support body 714. The second baffle 7140 has a second flange 7141 at one end away from the second support body 714. The second flange 7141 is folded toward the middle of the second support body 714. A third slot 7142 is provided between the second flange 7141 and the second baffle 7140. At least a portion of the other turntable 400 of the two turntables 400 is located in the third slot 7142. The first baffle 7110 has a first clearance opening 7113 between its two ends and the first support body 711, and the second baffle 7140 has a second clearance opening 7143 between its two ends and the second support body 714. The first clearance opening 7113 and the second clearance opening 7143 are opposite to each other. Each of the two turntables 400 is provided with a fixing ring 415, which is respectively locked in the second slot 7112 and the third slot 7142 and is in clearance fit with the second slot 7112 and the third slot 7142, so that the turntable 400 rotates relative to the tray 710. The first clearance opening 7113 and the second clearance opening 7143 are used to prevent the first baffle 7110 and the second baffle 7140 from contacting each other when the first support body 711 and the second support body 714 are relatively close, so as to prevent the two turntables 400 from generating an obstructive force.

[0065] Furthermore, the height adjustment mechanism 700 also includes a fixed cross brace 750 and a threaded rod 760. The fixed cross brace 750 is fixedly mounted on the vehicle body 100 and has a fourth through hole 751. One end of the threaded rod 760 is connected to the lifting frame 720, and the other end passes through the fourth through hole 751 and is threaded into the fourth through hole 751. By turning the threaded rod 760, the lifting frame 720 is driven to rise and fall in the vertical direction.

[0066] In the embodiments provided in this application, such as Figure 10As shown, each turntable 400 includes: a first disc body 410 connected to the transmission assembly 300; a sixth slide groove 411 provided on the first disc body 410, the sixth slide groove 411 extending radially along the first disc body 410; a slide groove opening 412 communicating with the sixth slide groove 411 provided on the second circumferential side 4101 of the first disc body 410; multiple sixth slide grooves 411, spaced apart along the circumferential direction of the first disc body 410; and multiple slide groove openings 412, which communicate with the multiple sixth slide grooves 411. Each slide groove 411 is correspondingly arranged; a moving rod 420 is inserted into the sixth slide groove 411 and extends out of the slide groove opening 412. The moving rod 420 is movably arranged along the extension direction of the sixth slide groove 411. There are multiple moving rods 420, and each moving rod 420 is correspondingly arranged with a sixth slide groove 411. Each moving rod 420 has a connecting end face 421 facing outward from the first disc body 410. A connecting ring 430 is fitted onto each moving rod 420 and fits against each connecting end face 421. The connecting ring 430 is made of elastic material. By cooperating with each moving rod 420, the diameter of the circumferential surface formed by each connecting end face 421 can be adjusted as each moving rod 420 moves along the radial direction of the first disc body 410, thereby adjusting the diameter of the connecting ring 430 to control the length of line laid per unit travel distance. The fixing ring 415 is disposed at the bottom of the first disc body 410 and extends along the circumferential direction of the first disc body 410. The fixing ring 415 protrudes relative to the second circumferential side 4101 of the first disc body 410.

[0067] Preferably, the connecting end face 421 is an arc-shaped surface, recessed towards the center of the first disc 410, and the connecting ring 430 fits against the arc-shaped surface; a limiting groove 431 is provided on the circumferential surface of the connecting ring 430 away from the connecting end face 421, and a through gap 402 is provided between the two connecting rings 430, with at least a portion of the cable 120 fitting against the bottom surface of the limiting groove 431. This arrangement can limit the cable 120 and prevent the cable 120 from drooping within the through gap 402.

[0068] Furthermore, a seventh groove 414 communicating with the sixth groove 411 is provided on the circumferential end face 413 of the first disc 410. The seventh groove 414 extends radially along the first disc 410, and there are multiple seventh grooves 414, each corresponding to one of the sixth grooves 411. Each moving rod 420 is provided with an extension rod 422, one end of which is connected to the end of the moving rod 420, and the other end of which passes through the seventh groove 414. The extension rod 422 is movably arranged along the extending direction of the seventh groove 414. Each extension rod 422 drives each moving rod 420 to move radially along the first disc 410.

[0069] In specific implementation, each turntable 400 further includes: a second disc body 440, which is disposed above the first disc body 410. The axis of the second disc body 440 is on the same straight line as the axis of the first disc body 410. The second disc body 440 is rotatably disposed relative to the first disc body 410. A third through hole 441 is provided on the second disc body 440. The third through hole 441 extends along an arc-shaped trajectory from the middle of the second disc body 440 toward the edge of the second disc body 440. The protruding rod 422 passes through the seventh slide groove 414 and is inserted into the third through hole 441. There are multiple third through holes 441, which are spaced apart along the circumferential direction of the second disc body 440. During normal wire laying, the second disc 440 rotates synchronously with the first disc 410. When it is necessary to adjust the diameter of the circumferential surface formed by the various connecting end faces 421, the second disc 440 is controlled to rotate relative to the first disc 410. Since the third through hole 441 extends along an arc trajectory, the intersection point with the extension rod 422 changes continuously during the rotation of the second disc 440. Thus, under the mutual blocking action of the third through hole 441 and the extension rod 422, the hole wall of the third through hole 441 pushes the extension rod 422 to move, thereby driving each moving rod 420 to move.

[0070] Specifically, each transmission assembly 300 includes a drive rod 320, which is rotatably arranged around a second axis. The drive rod 320 has multiple first slots 321, each extending along the axial direction of the drive rod 320. A first disc 410 and a second disc 440 are sequentially fitted onto the drive rod 320. The inner sidewall 403 of the first disc 410 has multiple first protrusions 404, each of which is respectively engaged with a first disc 404. A slot 321 is provided with a rotating cylinder 442 on the second disc 440. The rotating cylinder 442 extends from the end face of the second disc 440 toward a direction away from the first disc 410. An adjusting block 450 is provided inside the rotating cylinder 442. The adjusting block 450 is detachably connected to the rotating cylinder 442 so that the rotating cylinder 442 is connected to the drive rod 320 through the adjusting block 450, or so that the rotating cylinder 442 drives the second disc 440 to rotate relative to the first disc 410. The first disc 410 engages with each of the first protrusions 404 and the first slots 321, and can rise and fall along the extension direction of the first slots 321 as the drive rod 320 rotates. The second disc 440 is connected to or separated from the drive rod 320 via an adjusting block 450. When the adjusting block 450 is connected to both the second disc 440 and the drive rod 320, the second disc 440 and the first disc 410 rotate synchronously via the drive rod 320. When it is necessary to adjust the diameter of the circumferential surface formed by the connecting end faces 421, the adjusting block 450 is removed, and the rotating cylinder 442 drives the second disc 440 to rotate relative to the first disc 410. A third bearing 630 is provided between the drive rod 320 and the retainer 610.

[0071] Furthermore, an arc-shaped groove 4420 is provided on the cylinder wall surface of the rotating cylinder 442, and the arc-shaped groove 4420 is recessed relative to the cylinder wall surface facing the outer side of the rotating cylinder 442; the adjusting block 450 extends along the arc trajectory, and a plurality of second protrusions 4501 are provided on the adjusting block 450, each of the second protrusions 4501 extending along the axial direction of the adjusting block 450; the adjusting block 450 is engaged in the arc-shaped groove 4420, and each of the second protrusions 4501 is engaged in each of the first slots 321, so that the driving rod 320 drives the second disc 440 to rotate through the adjusting block 450. The adjusting block 450 is provided with a cover 451. The adjusting block 450 has an inner arc-shaped surface and an outer arc-shaped surface. Each second protrusion 4501 is provided on the inner arc-shaped surface, and the outer arc-shaped surface is in contact with the arc-shaped groove 4420. The cover 451 extends from the top surface of the adjusting block 450 toward the outer arc-shaped surface. At least part of the cover 451 is in contact with the top surface of the rotating cylinder 442, so that the adjusting block 450 is locked in the arc-shaped groove 4420. The second protrusion 4501 is locked in the first slot 321. By providing the cover 451, it is convenient to take out or put into the arc-shaped groove 4420.

[0072] In the cable laying device provided in this application, the vehicle body 100 is also provided with a tongue 800 for connecting to a drive mechanism to drive the vehicle body 100 to move. During the movement, the cable is discharged by the rotation and squeezing of two cable laying turntables 400. The turntables can be radially extended and retracted (the diameter of the circumference formed by each connecting end face 421) to control the cable laying length per unit travel distance, and to make fault tolerance settings. The amount of cable laid per unit short distance can be adjusted. This mechanism design can also be set according to the specific situation of cable laying, flexibly setting the length of cable laid per unit travel distance, avoiding the friction damage to the cable caused by accidental traction. At the same time, the height adjustment mechanism controls the cable exit position, greatly improving the flexibility of cable laying.

[0073] To avoid the significant speed difference between the traditional vehicle body and the cable laying mechanism, this invention connects the traveling mechanism to a transmission assembly. The transmission assembly includes two sets of vertical rotating units (a second bevel gear and a drive rod). During travel, the wheel axle of the traveling unit drives the two sets of vertical rotating units to rotate in opposite directions. Simultaneously, symmetrically mounted vertically sliding cable laying turntables (turntables 400) are mounted on the two sets of vertical rotating units. This allows the cable to be discharged during travel by the rotation and compression of the two turntables. To prevent relative slippage between the cable and the turntables, the turntables can radially extend and retract to control the cable laying length per unit travel distance, allowing for error tolerance. This design can also be customized according to specific cable laying conditions, flexibly setting the cable laying length per unit travel distance, avoiding damage caused by accidental cable entanglement. A height adjustment mechanism is used to adjust the height of the two turntables and control the cable exit position, greatly improving the flexibility of cable laying, adapting to various cable laying scenarios, and increasing work efficiency.

[0074] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0075] The wire feeding device provided by the present invention includes a vehicle body 100, a traveling mechanism 200, a transmission assembly 300, and a turntable 400. A wire spool 110 is disposed on the vehicle body 100, and a cable 120 is wound on the wire spool 110. The traveling mechanism 200 is disposed on the vehicle body 100 and includes a traveling frame 210, which is rotatably disposed about a first axis to drive the vehicle body 100 to move. One end of the transmission assembly 300 is connected to the traveling frame 210, and the other end of the transmission assembly 300 is connected to the turntable 400, so that during the rotation of the traveling frame 210, the cable spool 120 is moved via the transmission assembly 400. The component 300 drives the turntable 400 to rotate around the second axis, which is perpendicular to the first axis. There are two sets of transmission components 300, which are spaced apart along the axis of the walking frame 210. There are two turntables 400, which are respectively connected to the two sets of transmission components 300. A through gap 402 for the cable 120 to pass through is provided between the first circumferential side 401 of the two turntables 400. The two turntables 400 rotate in opposite directions so that the cable 120 is squeezed out from the through gap 402 during the rotation of the two turntables 400. This configuration allows the two sets of transmission components 300 to drive the two turntables 400 to rotate during the movement of the vehicle body 100 driven by the traveling frame 210. This enables the cable 120 to be squeezed out from the through gap 402. At this time, the rotation speed of the turntable 400 is proportional to the cable feeding speed, and the rotation speed of the turntable 400 is related to the traveling frame 210. That is, the cable feeding speed is linked to the moving speed of the vehicle body 100. Thus, during the movement of the vehicle body 100, the cable feeding speed is automatically adjusted according to the change in the moving speed of the vehicle body 100. There is no need for manual control of the cable feeding speed, which avoids a large deviation between the traveling speed of the vehicle body 100 and the cable feeding speed, thereby preventing wear on the cable 120 or the cable 120 from becoming tangled or coiled.

[0076] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
