The control end drives to change the rotation direction of the rotation shaft of the adjustment motor 161 to control the distance between the plurality of moving bases 16.

[0025] Refer to Figure 3 and Figure 5 , an adjustment cylinder 163 is provided on the bottom surface of the moving base 16. The adjustment cylinder 163 is parallel to the plane where the adjustment base 10 is located, and the piston rod of the adjustment cylinder 163 extends toward the center of the arc of the arc-shaped track bar 14. A rotating shaft is provided at the end of the piston rod of the adjustment cylinder 163. A tightening base 17 is rotatably provided at the end of the piston rod of the adjustment cylinder 163. A ball head seat 164 is provided at the end of the piston rod of the adjustment cylinder 163. A ball head 171 is provided at the top of the tightening base 17. The ball head 171 is rotatably provided in the ball head seat 164. Under the action of the gravity of the tightening base 17, the tightening base 17 is in a vertical state. A locking cylinder 165 is provided in the ball head seat 164. The piston rod of the locking cylinder 165 passes through the groove wall of the ball head seat 164. The piston rod of the locking cylinder 165 is used to abut against the surface of the ball head 171. After adjusting the inclination angle of the tightening base 17, the piston rod of the locking cylinder 165 is used to tightly abut against the surface of the ball head 171 to limit the rotation of the ball head 171 in the ball head seat 164.

[0026] Refer to Figure 3 , Figure 5 and Figure 6, a sliding cavity 172 is formed inside the tightening seat 17, and the sliding cavity 172 communicates with the bottom surface of the tightening seat 17. An extension rod 173 is slidably arranged inside the tightening seat 17, and the extension rod 173 is located inside the sliding cavity 172. The top end of the extension rod 173 is fixedly connected with a compression spring 174, and the other end of the compression spring 174 is fixedly connected with the top surface of the sliding cavity 172. The compression spring 174 is used to pull the extension rod 173 back to reset in the sliding cavity 172. The bottom end of the extension rod 173 is provided with a connecting hook 175, and a pressing wheel 176 is rotatably arranged at the bottom end of the connecting hook 175. The cable is wound around the surface of the pressing wheel 176. A reserved gap 178 is arranged between the top end of the connecting hook 175 and the top end of the pressing wheel 176, and the reserved gap 178 is used to place the cable between the connecting hook 175 and the pressing wheel 176. A limiting piece 179 is rotatably arranged on the surface of the connecting hook 175. The rotation axis of the limiting piece 179 is located at the top end of the connecting hook 175, and the length of the limiting piece 179 is greater than the distance between the rotation of the limiting piece 179 and the top end of the pressing wheel 176. When the limiting piece 179 naturally hangs down under the action of gravity, the limiting piece 179 closes the reserved gap 178 to prevent the cable from falling off from the reserved gap 178.

[0027] Referring to Figure 5 and Figure 6 , a driving rack 1710 is further arranged on the side surface of the extension rod 173, and the driving rack 1710 is vertically arranged. A connecting hole 1711 is formed inside the tightening seat 17, and the connecting hole 1711 penetrates through the side surface of the tightening seat 17 and communicates with the sliding cavity 172. Two auxiliary gears 1712 are respectively rotatably connected to the two side surfaces of the tightening seat 17. The two auxiliary gears 1712 are respectively located on the opposite sides of the tightening seat 17, and the auxiliary gears 1712 are meshed with the driving rack 1710 through the connecting hole 1711. When the extension rod 173 moves up and down inside the sliding cavity 172, the extension rod 173 drives the auxiliary gear 1712 to rotate through the driving rack 1710. An auxiliary rod 1713 is fixedly connected to the center of the auxiliary gear 1712, and a tightening wheel 1714 is rotatably connected to the end of the auxiliary rod 1713. The cable is sequentially wound around the surfaces of the tightening wheel 1714 and the pressing wheel 176.

[0028] Referring to Figure 7 , a limiting groove 1715 is formed on the side surface of the tightening wheel 1714, and two side clamping rings 1716 are further arranged on the side surface of the tightening wheel 1714. The side clamping rings 1716 are made of hard material or hard rubber material. As an optimal embodiment, the side clamping rings 1716 are made of hard material, and a rubber ring is installed between the side clamping rings 1716 and the tightening wheel 1714. It should be noted that Figure 7The figure in the middle shows the state of the cable clamp after deformation in the limiting groove 1715. The two side clamping rings 1716 are respectively located on both sides of the limiting groove 1715, and the distance between the side clamping rings 1716 is greater than the diameter of the cable. The two side clamping rings 1716 are respectively clamped on the opposite sides of the cable, and the side clamping rings 1716 make the cable wind more firmly on the tensioning wheel 1714.

[0029] Referring to Figure 8 , a correction bracket 18 is detachably installed on the bottom surface of the connection seat 11 through bolts. The position of the correction bracket 18 can be adjusted according to requirements. A correction hollow tube 181 is vertically arranged on the correction bracket 18, and the cable passes through the correction hollow tube 181. The correction hollow tube 181 is used to adjust the bent cable into a straight state and convey it to the tensioning wheel 1714. Rubber rings 182 are respectively arranged at both ends of the correction hollow tube 181, and the cable passes through the inside of the rubber rings 182.

[0030] Referring to Figure 8 , a plurality of adjustment tubes 183 and a plurality of connecting elastic pieces 184 are vertically arranged between the correction hollow tubes 181. The connecting elastic pieces 184 are arranged between two adjacent adjustment tubes 183, and both ends of the connecting elastic pieces 184 are fixedly connected to the two adjustment tubes 183 respectively. The adjustment tubes 183 are also connected to the correction hollow tubes 181 through the connecting elastic pieces 184. The cable passes through the inside of the adjustment tubes 183 and the connecting elastic pieces 184 in sequence. A vibration motor 185 is arranged on one of the adjustment tubes 183. The vibration motor 185 drives the adjustment tube 183 to vibrate, eliminating the stress in the cable to achieve the purpose of straightening, facilitating subsequent cable laying and reducing cable bending.

[0031] The working process of this embodiment is as follows: According to the type and laying requirements of the cable, the control end outputs a control signal to the adjustment motor 161. The adjustment motor 161 is meshed and connected to the arc rack 15 through the adjustment gear 162, controlling the movement of the moving seat 16 along the arc track bar 14 and adjusting the distance between the moving seats 16. The greater the distance between the moving seats 16, the wider the distance between the laid cables. Conversely, the narrower the distance between the laid cables.

[0032] Then, according to the type and laying requirements of the cable, by controlling the elongation length of the piston rod of the adjustment cylinder 163, the height of the tensioning seat 17 is adjusted, so that the pressing wheel 176 abuts against the ground, and the pressing force between the pressing wheel 176 and the ground is controlled by the adjustment cylinder 163. During the upward sliding process of the extension rod 173 into the sliding cavity 172, the driving rack 1710 is used to push the auxiliary gear 1712 to rotate, and the included angle between the two auxiliary rods 1713 increases, realizing the automatic control of cable regulation.

[0033] When the wire laying is completed, the pressing wheel 176 separates from the ground. Under the action of the compression spring 174, the extension rod 173 is pushed out of the sliding cavity 172. During this process, the driving rack 1710 pushes the auxiliary gear 1712 to rotate in the reverse direction, reducing the angle between the two auxiliary rods 1713 to reduce the volume. Embodiment

[0034] Refer to Figure 9 , this embodiment provides a mobile cable engineering vehicle, which includes the engineering vehicle 20 and the cable laying device described in the above embodiment. The cable laying device is installed at the wire laying end of the engineering vehicle 20, and the overall wire laying of the cable laying device is realized through the movement of the engineering vehicle 20. The engineering vehicle 20 serves as a power source and, in cooperation with the laying device, can accurately control the position and speed of cable laying, while improving the flexibility and efficiency of operation.

[0035] It should be noted that the engineering vehicle 20 is equipped with a wire laying wheel, a wire guiding wheel, etc., which can ensure the smooth release of the cable during the laying process. The design of the wire laying wheel ensures that the cable can maintain uniform tension and appropriate wire laying speed during laying, effectively preventing problems such as knotting or damage caused by the cable being too tight or too loose. The wire laying wheel is connected to the power system of the engineering vehicle and can precisely adjust the wire laying speed of the cable to ensure its stability.

[0036] In addition, the engineering vehicle 20 is also equipped with a swing arm similar to that of an excavator. This design greatly improves the adjustability and automation degree of the laying device. By adjusting the angle of the swing arm, the operator can change the wire laying direction and angle of the wire laying device according to needs to adapt to the laying requirements in different construction environments. For example, in complex terrains or narrow spaces, the swing arm can flexibly adjust the wire laying angle to ensure that the cable can be smoothly laid to the target position, thereby improving the overall work efficiency.

[0037] Combining the movement function of the engineering vehicle 20 and the angle adjustment of the swing arm, the cable laying device of the present invention can achieve efficient and precise laying operations, and has strong adaptability, suitable for laying requirements in different environments. This laying device with a relatively high degree of automation reduces the dependence on manual operations and improves the construction efficiency and safety.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
