[0033] In the present invention, the terms "disposed", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] See also Figure 1 and Figure 2 An embodiment of the present application provides a cable feeding device, including a first auxiliary feeding structure 1 and a second auxiliary feeding structure 2, the first auxiliary feeding structure 1 including a first bracket 11, a longitudinal roller 12 and a transverse roller 13, the first bracket 11 has a first direction and a second direction at angles to each other, the longitudinal roller 12 is connected to the first bracket 11 along the first direction, and the transverse roller 13 is connected to the first bracket 11 along the second direction; the second auxiliary feeding structure 2 includes a second bracket 21 and a second roller 22, the second bracket 21 includes a plurality of folding plates 211 connected in sequence along its length direction, and each folding plate 211 is connected to the second roller 22.

[0039] For the sake of clarity, Figure 1The X direction represents the first direction, and the Y direction represents the second direction; in practical applications, the first direction can be parallel to the vertical direction, and the Y direction can be parallel to the horizontal direction, so that the first direction and the second direction are arranged perpendicular to each other, the longitudinal roller 12 is arranged along the first direction, that is, the longitudinal roller 12 rotates with the first direction as the rotation axis, and the transverse roller 13 is arranged along the second direction, that is, the transverse roller 13 rotates with the second direction as the rotation axis. In this way, the transverse roller 13 is mainly used to assist in wire feeding. When the cable needs to be transported for a long and straight distance, the cable is placed on the transverse roller 13, and there is rolling friction between the transverse roller 13 and the cable. Compared with the sliding friction generated by the direct contact between the cable and the ground, the friction force of rolling friction is smaller, which is more convenient for operators to pull the cable. When the cable needs to turn, the cable can be placed on the longitudinal roller 12, which plays a role of lateral support for the cable, and the rotation of the roller can assist the cable to turn, so as to facilitate the cable to pass the corner smoothly.

[0040] The present application also provides a second auxiliary wire feeding structure 2, which includes a second bracket 21 and a second roller 22. The second bracket 21 is formed by a plurality of folding plates 211 connected in sequence, and the connection angles between the plurality of folding plates 211 can be adjusted, that is, the second bracket 21 can be a bent and extended structure. When the cable is transported on a sloped ground, the bent second bracket 21 can be adapted to a position with a height difference such as a slope or a concavity, so that the second bracket 21 is more stable when placed at a position with a height difference such as a slope or a concavity. In this way, when the cable is placed on the second roller 22, the cable is transported more smoothly, preventing the second bracket 21 from becoming unstable and tipping over during transportation, thereby affecting the normal progress of the cable transportation work.

[0041] Compared with the prior art, the first auxiliary wire feeding structure 1 of the present application integrates a transverse roller 13 and a longitudinal roller 12. The transverse roller 13 is mainly used to assist the cable in long-distance straight-line transportation, and the longitudinal roller 12 is mainly used to assist the cable in steering, making it more convenient to transport the cable in narrow locations or corners; and by setting up a second auxiliary wire feeding structure 2, the second auxiliary wire feeding structure 2 can adapt to location environments with height differences such as slopes or concavities, which facilitates the transportation of cables in locations with height differences, increases the use scenarios of the device, makes the functions more diverse, and improves the practicability of the device.

[0042] See again Figure 2 The second bracket 21 includes a hinge 212, which is respectively connected to two adjacent folding plates 211. The folding plates 211 include a bottom 2111 and a side 2112. The bottom 2111 is connected to the side 2112 on both opposite sides. The side 2112 can be a triangle or a trapezoid. The second roller 22 is rotatably connected to the side 2112 on both opposite sides.

[0043] In actual applications, a hinge 212 is provided between the folding plates 211 and 211, and the hinge 212 can be rotatably connected to two adjacent folding plates 211 respectively, so that the two adjacent folding plates 211 can rotate relative to each other. In this way, when the second bracket 21 is placed in a sloped or concave position, the second bracket 21 can adapt to the ground, thereby increasing the stability of the second bracket 21 in contact with the ground, thereby increasing the stability of cable transportation.

[0044] In one embodiment, the folding plate 211 may include a bottom 2111 and side portions 2112 connected to opposite sides of the bottom plate, the bottom 2111 is used to contact the ground, and the side portions 2112 are used to connect to the second roller 22 .

[0045] It should be noted that the hinge 212 can adopt a structure of a fixed plate and a pin. For example, the fixed plate is rotatably connected to two adjacent folding plates 211 through pins to achieve the effect that the two adjacent folding plates 211 can rotate relative to each other. The hinge 212 can also adopt a hinge. When the hinge 212 adopts a hinge, the hinge 212 can be fixedly connected to the folding plate 211.

[0046] See again Figure 1 The first bracket 11 includes a transverse portion 111 and a vertical portion 12 , the transverse portion 111 is vertically connected to the vertical portion 12 , the longitudinal roller 12 is arranged parallel to the vertical portion 12 , and the transverse roller 13 is arranged parallel to the transverse portion 111 .

[0047] In actual application, the first bracket 11 adopts an L-shaped structure, including a horizontal portion 111 and a vertical portion 12 that are vertically connected to each other. The horizontal portion 111 is used for rotational connection of the longitudinal roller 12, and the vertical portion 12 is used for rotational connection of the horizontal roller 13. The L-shaped structure facilitates the installation and arrangement of the first bracket 11. For example, it can be placed against a wall during work to improve the stability of the first bracket 11. The L-shaped structure has a flexible spatial layout, which is conducive to being placed in a relatively narrow or rugged space.

[0048] See again Figure 1 The first auxiliary wire feeding structure 1 also includes a longitudinal limiting wheel 14 and a transverse limiting wheel 15. The longitudinal limiting wheel 14 is arranged in parallel with the longitudinal roller 12, and a first wire passing space 16 is formed between the longitudinal limiting wheel 14 and the longitudinal roller 12; the transverse limiting wheel 15 is arranged in parallel with the transverse roller 13, and a second wire passing space 17 is formed between the transverse limiting wheel 15 and the transverse roller 13; the first wire passing space 16 and the second wire passing space 17 are both used for the cable to pass through.

[0049] In actual application, in order to prevent the cable from escaping from the transverse roller 13 or the longitudinal roller 12 during transportation, the present application provides a transverse limiting wheel 15 and a longitudinal limiting wheel 14. The longitudinal limiting wheel 14 is arranged parallel to the longitudinal roller 12 and forms a first wire passing space 16. The transverse limiting wheel 15 is arranged parallel to the transverse roller 13 and forms a second wire passing space 17. The first wire passing space 16 and the second wire passing space 17 are for the cable to pass through and are used to limit the cable to prevent the cable from escaping from the transverse roller 13 and the longitudinal roller 12.

[0050] It should be noted that both the longitudinal roller 12 and the transverse roller 13 are provided with groove structures such as V-shaped grooves or U-shaped grooves. This groove structure is convenient for placing cables. At the same time, the surface of the groove structure can be made of flexible materials, such as soft rubber, to protect the cables.

[0051] See again Figure 1 The first bracket 11 is provided with a first adjustment groove 18 and a second adjustment groove (not shown in the figure), the first adjustment groove 18 extends along the second direction, the second adjustment groove extends along the first direction, the longitudinal limiting wheel 14 is arranged in the first adjustment groove 18, and the transverse limiting wheel 15 is arranged in the second adjustment groove.

[0052] In actual applications, since the first adjustment groove 18 extends along the second direction, the longitudinal limiting wheel 14 can be fixed at any position along the length direction of the first adjustment groove 18. Therefore, the first adjustment groove 18 is used to adjust the distance between the longitudinal limiting wheel 14 and the longitudinal roller 12 to adapt to cables of different diameters and thicknesses; similarly, the second adjustment groove is used to adjust the position of the transverse limiting wheel 15, and then adjust the distance between the transverse limiting wheel 15 and the transverse roller 13 to adapt to cables of different diameters and thicknesses.

[0053] It should be noted that the longitudinal limiting wheel 14 and the transverse limiting wheel 15 can be made of elastic material, and the distance from the first wire passing space 16 or the second wire passing space 17 can be adjusted through their own elasticity to meet the requirements of cable routing of different thicknesses.

[0054] See again Figure 1 The first bracket 11 includes a first support plate 113 and a second support plate 114. The first support plate 113 is connected to the vertical portion 12 and is arranged parallel to the horizontal portion 111. The second support plate 114 is connected to the first support plate 113 and is arranged parallel to the vertical portion 12. The longitudinal rollers 12 are rotatably connected to the first support plate 113 and the horizontal portion 111 respectively, and the horizontal rollers 13 are rotatably connected to the second support plate 114 and the vertical portion 12 respectively. A chamfered portion 1131 is provided on the side of the first support plate 113.

[0055] In practical applications, the first support plate 113 is arranged parallel to the horizontal portion 111 and spaced apart. On the one hand, it is convenient to connect the longitudinal roller 12. On the other hand, the first support plate 113 can play the role of spacing the transverse roller 13 to prevent the cable from contacting the longitudinal roller 12 when sliding on the transverse roller 13. At the same time, the first support plate 113 can play the role of supporting the cable, and a chamfered portion 1131 is arranged on the side of the first support plate 113. When the chamfered portion 1131 contacts the cable, it can protect the outer layer of the cable and prevent the cable from being damaged. The second support plate 114 is arranged parallel to the vertical portion 12 and spaced apart. On the one hand, it is convenient to install the transverse roller 13. On the other hand, the second support plate 114 can also play a limiting role to prevent the cable from detaching from the transverse roller 13.

[0056] See also Figure 3 and Figure 4 The cable feeding device also includes a wire pulling structure 3, which includes a hook rod 31 and a connecting piece 32. The connecting piece 32 is used to be fixed to the cable, and the hook rod 31 is used to hook the connecting piece 32.

[0057] In actual applications, when the cable is being transported, it is also necessary to cooperate with the pulling wire structure 3 to pull it out from the pipeline or other locations. Specifically, the connecting piece 32 is fixedly connected to the cable head, and then the hook rod 31 hooks the connecting piece 32. The hook rod 31 is pulled manually or electrically, so that the hook rod 31 drives the cable to move for transportation.

[0058] See again Figure 3 The connecting member 32 includes an inner cylinder 321, an outer cylinder 322 and a connecting portion 323. The inner cylinder 321 includes a plurality of clamping portions 3211 arranged at intervals along its circumferential direction. The plurality of clamping portions 3211 enclose a wire fixing groove 3212. The wire fixing groove 3212 is used to place the cable. The connecting portion 323 is connected to the end of the inner cylinder 321 and is used for the hook rod 31 to hook. The outer cylinder 322 is movably connected to the outer periphery of the inner cylinder 321. The outer cylinder 322 is used to push the clamping portion 3211 to shrink into the wire fixing groove 3212.

[0059] In practical applications, one end of the cable is inserted into the cable fixing groove 3212, and the outer cylinder 322 is movably connected to the outer periphery of the inner cylinder 321, that is, the outer cylinder 322 can slide or rotate relative to the inner cylinder 321. For example, when the outer cylinder 322 slides relative to the inner cylinder 321, the outer cylinder 322 can push the multiple clamping parts 3211 to shrink into the cable fixing groove 3212, so that the multiple clamping parts 3211 clamp the cable, thereby achieving the fixing effect of the cable and the connector 32. The side of the clamping part 3211 close to the cable can be provided with anti-slip teeth to increase the clamping force and friction of the clamping part 3211 on the cable, and improve the connection stability between the cable and the clamping part 3211.

[0060] See also Figure 3In one embodiment, the connecting portion 323 is provided with a hook groove 3231, and the hook groove 3231 is used for the hook rod 31 to be hooked, so that the operator can pull the cable.

[0061] See also Figure 6 The connecting part 323 is provided with a lamp groove 3234 along its circumference, and a connecting groove 3235 along its axial direction. In practical applications, the lamp groove 3234 is mainly used to install light-emitting parts such as light bulbs. When operators are working in a relatively dark environment, the light bulbs can provide light for the construction environment, which is convenient for operators to install the connecting piece 32; the connecting part 323 is provided with a connecting groove 3235, which can be connected to an external connecting rod, and the length of the connecting piece 32 is extended by the connecting rod. In some relatively narrow areas, when it is inconvenient for the hook rod 31 to hook the connecting piece 32, the connecting piece 32 can be connected to the connecting piece 32 through the connecting rod, such as a threaded connection. At this time, the operator only needs to pull the connecting rod to pull out the cable, and then hook the hook rod 31.

[0062] See also Figure 7 In one embodiment, the connecting portion 323 may include a first portion 3232 and a second portion 3233. The first portion 3232 is connected to the inner tube 321 and is provided with a lamp groove 3234. The second portion 3233 is connected to the first portion 3232 and is provided with a connecting groove 3235. The connecting groove 3235 is used to install a connecting rod. The opposite sides of the second portion 3233 extend away from the first portion 3232 to form an extension portion 3236. The extension portion 3236 is used for the hook rod 31 to hook.

[0063] In practical applications, the connecting member 32 can integrate the lamp groove 3234, the connecting groove 3235 and the hook groove 3231 at the same time. Specifically, an annular groove is formed between the extension portion 3236, the first portion 3232 and the inner tube 321, and the annular groove can be used as the hook groove 3231. At this time, the hook rod 31 can be used as follows: Figure 5 The structure shown is arranged in this way, which increases the functional diversity of the connecting member 32 and improves the practicality of the connecting member 32. The connecting member 32 can be connected to the connecting rod and can also be hooked by the hook rod 31.

[0064] See also Figure 8 The outer cylinder 322 is threadedly connected to the inner cylinder 321 . The outer cylinder 322 includes a contact portion 3221 . The contact portion 3221 is attached to the clamping portion 3211 . When the outer cylinder 322 rotates relative to the inner cylinder 321 , the contact portion 3221 pushes the clamping portion 3211 toward the wire fixing groove 3212 .

[0065] In practical applications, the outer cylinder 322 can be connected to the inner cylinder 321 by threading. Along the axial direction of the inner cylinder 321, from the connecting portion 323 to the direction of the inner cylinder 321, the abutting portion 3221 extends obliquely toward the clamping portion 3211. When the outer cylinder 322 rotates relative to the inner cylinder 321, that is, when the outer cylinder 322 moves toward the direction of the connecting portion 323, the abutting portion 3221 pushes the clamping portion 3211 to move into the cable fixing groove 3212 to clamp the cable. The threaded connection has a self-locking function. When the outer cylinder 322 is not subjected to external force, the outer cylinder 322 and the inner cylinder 321 are fixed to each other and will not rotate relative to each other, so that the clamping portion 3211 can continuously clamp the cable to prevent the cable from being detached.

[0066] The embodiment of the present application also provides a cable feeding method, which adopts one or more of the above-mentioned cable feeding devices. The cable feeding method includes: first, extending one end of the cable into the cable fixing groove 3212, rotating the outer cylinder 322, so that the clamping part 3211 of the inner cylinder 321 clamps the cable, and completes the fixation of the cable and the connecting member 32; then connecting the connecting member 32 with the hook rod 31 or the connecting rod, setting the hook rod 31 or the connecting rod on the motor, and then placing the first auxiliary wire feeding structure 1 or the second auxiliary wire feeding structure 2 along the length direction of the cable.

[0067] The specific placement method is: place the first auxiliary wire feeding structure 1 on the straight conveying path, and place the cable on the transverse roller 13 in the first auxiliary wire feeding structure 1; place the first auxiliary wire feeding structure 1 at the position where turning is required, and place the cable on the longitudinal roller 12 in the first auxiliary wire feeding structure 1; place the second auxiliary wire feeding structure 2 at a position with a height difference such as a slope or concavity, and then place the cable on the second roller 22. After the setting is completed, start the motor to realize the cable transportation.

[0068] It should be noted that the first auxiliary wire feeding structure 1 is placed in a manner in which the horizontal portion 111 is in contact with the ground.
