[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an integrated device for cable laying, comprising a vehicle body 100, a traveling device 200, a supporting device 300, a lifting device 400, and a traction device 500.

[0023] The traveling device 200 is connected to the vehicle body 100 and is used to drive the vehicle body 100 to move; the supporting device 300 is connected to the vehicle body 100 and can support and fix the vehicle body 100; the lifting device 400 is installed on the vehicle body 100 and can lift and place objects; the traction device 500 is installed on the vehicle body 100 and is used to connect to the cable to be laid and can pull the cable to move.

[0024] The traveling device 200 drives the vehicle body 100 to move. The traveling device 200 enables the self-transfer of the lifting device 400 and the traction device 500 without the need for other equipment for hoisting. During the movement of the vehicle body 100, the lifting device 400 can also be used to lift away objects that need to be moved along the way, such as lifting open the cover of a cable trench to facilitate cable laying. Once the vehicle body 100 reaches the predetermined position, which is generally the end point of cable laying, the traction device 500 pulls the cable until the cable end is pulled to the laying endpoint, completing the cable laying. The support device 300 is used to fix the vehicle body 100. When the lifting device 400 or the traction device 500 is working, the support device 300 is needed to resist the reaction force and prevent the vehicle body 100 from moving.

[0025] The support device 300 specifically includes multiple telescopic support rods, one end of which is hinged to the vehicle body 100. The swing amplitude and extension length of the support rods are controlled by hydraulic drive. For example, a hydraulic cylinder can be used to drive the swing amplitude and extension length of the support rods. It's important to understand that, generally, the support device 300 only needs two states: a supported state and a non-supported state. Therefore, the retraction limit of the hydraulic cylinder can correspond to the non-supported state, and the extension limit can correspond to the supported state, meeting the usage requirements. In the supported state, the support device 300 has good contact with the bearing surface, which can be the ground.

[0026] Reference Figure 3 As shown, it can be understood that the traction device 500 includes a traction rope and a take-up assembly 510, one end of which is wound around the take-up assembly 510, and the other end of which is used to secure a cable. The take-up assembly 510 is capable of rotating and winding the traction rope.

[0027] Specifically, the take-up assembly 510 can be a cylindrical component driven by a motor to rotate. During the rotation, the traction rope is gradually tightened and wound around the take-up assembly 510. The traction rope is pulled by the take-up assembly 510, gradually pulling the cable at the other end of the traction rope to the position of the traction device 500, that is, the end point of the cable laying.

[0028] It is understood that the traction device 500 also includes a traction drive assembly 520. The traction rope is wound N times on the traction drive assembly 520 and then wound on the take-up assembly 510. The traction drive assembly 520 can rotate to take up and release the traction rope. The rotation axis of the traction drive assembly 520 is parallel to the rotation axis of the take-up assembly 510, where N≥2.

[0029] The traction drive assembly 520 can also be a scheme in which a motor drives the rotation of a cylindrical component. Adding the traction drive assembly 520 increases the tension of the traction rope. Specifically, after the traction rope wraps around the traction drive assembly 520 multiple times, the contact area between the traction rope and the traction drive assembly 520 increases, resulting in increased static friction. Therefore, the power of the motor in the traction drive assembly 520 can be increased, increasing torque and improving the tension on the traction rope, enabling the traction of longer distances and heavier cables. With the addition of the traction drive assembly 520, the cable traction force is mainly provided by the traction drive assembly 520, and the take-up assembly 510 is only used for winding and storing the traction rope, significantly reducing the output power of the take-up assembly 510.

[0030] Reference Figure 4As shown, it can be understood that the traction device 500 also includes a guide wheel 530, the rotation axis of which is parallel to the rotation axis of the traction drive assembly 520, and the winding path of the traction rope is, in sequence, the guide wheel 530, the traction drive assembly 520, and the take-up assembly 510.

[0031] The guide wheel 530 is used to change the transmission path of the traction rope, facilitating the optimization of the layout of the traction drive assembly 520 and the take-up assembly 510. Specifically, when the traction rope comes into frictional contact with the contours or edges of other equipment during movement, the guide wheel 530 can be installed at the contact point to reduce the frictional resistance of the traction rope and extend its service life.

[0032] Understandably, the traction device 500 also includes a fixed bracket 540, which is detachably connected to the vehicle body 100. The cable take-up assembly 510, the traction drive assembly 520, and the guide wheel 530 are all mounted on the fixed bracket 540.

[0033] The cable take-up assembly 510, traction drive assembly 520, guide wheel 530, and fixed bracket 540 together constitute a modular assembly, making the traction device 500 and the vehicle body 100 detachable as a whole, improving the expandability of the vehicle body 100. It should be understood that a first connecting seat can be provided on the vehicle body 100, and a second connecting seat can be provided on the fixed bracket 540. Both the first and second connecting seats have connecting holes. The fixed bracket 540 is connected to the vehicle body 100, with the connecting holes of the first and second connecting seats coaxial. A fixing pin is then inserted into the connecting hole to complete the connection between the fixed bracket 540 and the vehicle body 100. Simultaneously, the fixing pin can be removed, allowing the fixed bracket 540 to be detached from the vehicle body 100. It is also important to understand that the combination of the first connecting seat, the second connecting seat, and the fixing pin constitutes a detachable fixing module. Similarly, multiple detachable fixing modules can be installed on the vehicle body 100. Through the connection of the detachable fixing modules, various auxiliary cable laying components or auxiliary construction components can be quickly connected to the vehicle body 100 for use.

[0034] It is understood that the fixed bracket 540 is provided with multiple support legs 550. Each support leg 550 includes a fixed part 551 and an extension part 552. The extension part 552 is inserted into the fixed part 551. A hydraulic drive is provided between the extension part 552 and the fixed part 551. The hydraulic drive can drive the extension part 552 to move.

[0035] Typically, the traction device 500 is located at the front or rear end of the vehicle body 100. When the traction device 500 applies traction force to the cable, it may cause uneven stress on the vehicle body 100. It is difficult to fix the vehicle body 100 solely with the support device 300. Therefore, multiple support legs 550 can be added to the fixed bracket 540 for auxiliary fixation. Each support leg 550 includes a fixed part 551 and an extension part 552. The fixed part 551 is used to connect to the fixed bracket 540, and the extension part 552 is inserted into the fixed part 551 and moved by a hydraulic drive to change the length of the support leg 550. It should be understood that when the support leg 550 is needed for auxiliary support, the extension part 552 extends beyond the fixed part 551 and contacts the bearing surface, such as the ground. The hydraulic drive can be a hydraulic cylinder. Hydraulic cylinders are mature components, so the connection structure between the hydraulic cylinder and the extension part 552 is not described in detail and is not illustrated.

[0036] Reference Figure 5 As shown, it can be understood that the lifting device 400 includes a lifting boom 410, a lifting cylinder 420, a winding assembly 430, a steel cable 440, and a hook 450. The lifting boom 410 is hinged to the vehicle body 100. The lifting cylinder 420 is drivenly connected to the lifting boom 410 to drive the lifting boom 410 to swing around the hinge point. One end of the steel cable 440 is connected to the winding assembly 430, and the other end of the steel cable 440 passes through the suspended end of the lifting boom 410 and is connected to the hook 450.

[0037] The lifting cylinder 420 drives the boom 410 to swing, changing its tilt angle. The reel assembly 430 controls the length of the steel cable 440, ultimately moving the hook 450 to lift and lower the load. Furthermore, an overload protection device can be installed, which will automatically alarm when the load on the hook 450 exceeds its rated load, ensuring construction safety. For example, the steel cable 440 can be connected to the suspended end of the boom 410 via a fixed pulley. A strain gauge can be installed on the fixed shaft of the pulley, allowing real-time monitoring of the tension in the steel cable 440, which can be equivalently converted to the load on the hook 450.

[0038] It is understandable that the cross-sectional shape of the boom 410 is a regular hexagon, and in the cross-section of the boom 410, the connecting line between two opposite vertices of the regular hexagon is set horizontally.

[0039] It is important to understand that when the vehicle body 100 is in a horizontal plane, the swing plane of the crane boom 410 is a vertical plane. At this time, the line connecting two opposite vertices of the regular hexagonal cross-section of the crane boom 410 is horizontal, as shown below. Figure 6 The structure shown is described above. With the same amplitude or tilt angle, the lifting boom 410 has a greater lifting capacity and stronger resistance to local instability.

[0040] Reference Figure 7 As shown, it can be understood that the vehicle body 100 is provided with a slewing assembly 600, which is capable of rotating in the horizontal plane, and the boom 410 is hinged to the slewing assembly 600.

[0041] The slewing assembly 600 can extend the working range of the boom 410, for example, to achieve 360° rotation. The slewing assembly 600 can adopt a turntable structure, with a full rotation of gear teeth on the outer side of the turntable. A transmission gear is driven by a motor to rotate, and the transmission gear meshes with the gear teeth of the turntable for transmission.

[0042] It is understood that the walking device 200 includes two sets of track wheels 210, which are symmetrically arranged on the vehicle body 100 in a vertical plane.

[0043] The track rollers 210 possess excellent terrain adaptability, enabling them to traverse various terrains without fear of small bumps or potholes. By increasing the contact area with the ground, the track rollers 210 significantly reduce the pressure on the ground while simultaneously enhancing friction, providing stronger driving force. Furthermore, the large contact area of ​​the track rollers 210 also enhances the stability of the vehicle body 100.

[0044] It should be understood that the power source of this application can be an electric motor or a fuel engine, both of which are existing technologies. Those skilled in the art are familiar with the specific transmission connection schemes used to drive the traveling device 200, support device 300, lifting device 400, and traction device 500 to perform corresponding actions. This application also provides a more preferred combination: specifically, a dual-power combination of a diesel engine and an electric motor, which can provide a unified power supply to the connected devices or components. The diesel engine can also generate electricity for the electric motor, offering strong adaptability. This combination not only meets the power requirements of the traveling device 200 and the lifting device 400 but also provides a hydraulic oil source (driving the oil pump) for the added traction device 500.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
