[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a traveling assembly 100, including a vehicle body 101, with a front wheel set 102 and a rear wheel set 103 at both ends of the vehicle body 101; wherein the front wheel set 102 can be directional or steerable, so as to facilitate the turning of the vehicle body 101. A laying assembly 200 includes a frame 201 disposed on the vehicle body 101 and close to the rear wheel set 103.

[0031] A cable reel 202 is provided on the frame 201, and the cable reel 202 is wrapped with a cable. A trenching assembly 204 for trenching is provided in the middle of the vehicle body 101. In this embodiment, when the vehicle body 101 is moving, a trench for laying cables is first opened on the ground by the trenching assembly 204, and then the cable on the cable reel 202 is laid into the trench. During the laying process, the cable reel 202 will rotate synchronously with the movement of the vehicle body 101 to ensure the steady progress of cable laying. Compared with manual and mechanical trenching, this laying method causes less damage to the ground, and trenching and laying are carried out synchronously in the forward direction, which can greatly improve the laying efficiency. The whole process can be remotely controlled by humans. During the construction process, the construction technology relies on the explanation, and the laying quality is stable and guaranteed.

[0032] The trenching assembly 204 includes a plow support 204a rotatably mounted on the vehicle body 101, and the plow support 204a is provided with an upper plow blade 204b and a lower plow blade 204c arranged in an up-and-down manner, and a cable arrangement box 204d for cable arrangement is provided on the plow support 204a and on a side away from the upper plow blade 204b and the lower plow blade 204c. Under normal conditions, the plow support 204a is stored on the vehicle body 101 in parallel with the vehicle body 101, which is convenient for the movement of the vehicle body 101. When in use, the plow support 204a is rotated so that the upper plow blade 204b and the lower plow blade 204c thereon are deeply buried underground, so as to achieve the effect of digging a suitable trench with the movement of the vehicle body 101. At the same time, the cable arrangement box 204d set on the plow support 204a can lay the cable in the trench to complete the laying work. Compared with manual excavation, this trenching method not only improves the laying rate of the cable, but also saves labor costs.

[0033] The cable duct 204g for passing the cables is provided in the cable duct box 204d, and the two ends of the cable duct 204g are provided with a cable inlet 204e and a cable outlet 204f, respectively, and the number of the cable duct 204g is not unique. In this embodiment, the cables are laid by being guided by the cable duct 204g, and by setting the number of the cable duct 204g, the number of cables laid synchronously can be controlled, solving the problem of inconvenience in laying multiple cables simultaneously in the existing cable laying process.

[0034] The cable duct 204g is in a straight line shape, which can provide orderly cable laying management without clutter, making it easier for electricians to repair or replace lines later, thereby improving work efficiency.

[0035] When in use, through the setting of the trenching component 204 and the cable reel 202, trenches can be opened and cables can be laid while the vehicle body 101 is moving. Compared with manual or mechanical trenching, this laying method causes less damage to the ground, and trenching and laying are carried out simultaneously in the forward direction, which can greatly improve the laying efficiency. In addition, the setting of multiple cable troughs 204g can control the number of cables laid simultaneously, solving the problem of the inconvenience of laying multiple cables at the same time in the existing cable laying process.

[0036] Example 2

[0037] Reference Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that the cable duct 204g is bent. The bent cable duct 204g can guide the laying of cables according to laying needs, thereby increasing the laying efficiency to a certain extent.

[0038] A shaft 206 is provided in a sliding sleeve at the axis of the cable reel 202, and a fixing block 207 that conflicts with the cable reel 202 is detachably installed at both ends of the shaft 206. A hanging ear 205 for placing the shaft 206 is provided on the frame 201, and the hanging ear 205 conflicts with the fixing block 207. When in use, the fixing block 207 at one end of the shaft 206 is first removed, and after it is inserted into the axis of the cable reel 202, it is installed. After the installation is completed, the cable reel 202 is hoisted onto the hanging ear 205 by a crane or an excavator. As the cable is laid, the cable reel 202 automatically rotates. In addition, due to the mutual conflict between the fixing block 207 and the hanging ear 205, the cable reel 202 is not easy to detach from the frame 201, which increases the stability of cable laying.

[0039] The vehicle body 101 is provided with an auxiliary component 203 for assisting in laying cables. The auxiliary component 203 includes a support frame 203a fixedly mounted on the vehicle body 101, and the support frame 203a is rotatably mounted with a conveying chain plate 203b for accelerating the progress of cable laying. The provision of the conveying chain plate 203b can increase the laying efficiency of the cables. During laying, the cables are located between the conveying chain plates 203b, and the friction force will accelerate the movement efficiency of the cables. In addition, the conveying chain plates 203b are made of rubber, which can reduce the damage to the outside of the cables to a certain extent and extend their service life.

[0040] When in use, by changing the position of the cable outlet 204f, it is convenient for the staff to guide the laying of the cable and improve the laying efficiency. At the same time, through the mutual interference between the fixed block 207 and the hanging ear 205, the cable reel 202 is not easy to detach from the frame 201, which increases the stability of the cable laying. In addition, when laying, the cable is located between the conveying chain plates 203b. Under the action of the friction between the conveying chain plates 203b and the cable, the movement efficiency of the cable can be accelerated.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] Reference Figures 1 to 8 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: a traction assembly 300 for assisting the vehicle body 101 to move is provided on the vehicle body 101 and near the front wheel group 102, and the traction assembly 300 includes a traction motor 301 fixedly installed on the vehicle body 101, and a traction reel 303 coaxially fixed with the output shaft of the traction motor 301 is rotatably installed on the vehicle body 101, and a traction rope for traction is wound around the outside of the traction reel 303. Since the vehicle body 101 is a non-powered design, a tractor is generally provided in front of the vehicle body 101, but compared with the traditional design, the traction reel 303 for winding the traction rope is provided on the vehicle body 101 near the front wheel group 102 in this embodiment, and this arrangement balances the weight of the cable reel 202 provided at the rear wheel group 103 on the vehicle body 101, and to a certain extent, prevents the vehicle body 101 from falling backward. When in use, first fix one end of the traction rope on the traction reel 303 on the traction vehicle. After the traction vehicle is fixed in front, the traction motor 301 can be started to drive the traction reel 303 to rotate, and the tension brought by the traction rope can be used to drive the vehicle body 101 to move forward, thereby achieving cable laying.

[0044] The vehicle body 101 is provided with a traction rope hole 302 for sliding the traction rope. The traction rope is connected to the tractor only after passing through the traction rope hole 302, which can prevent the traction rope from shaking left and right, and to a certain extent, the traction force drives the vehicle body 101 in one direction, ensuring the stability of the vehicle body 101.

[0045] When in use, the traction reel 303 is arranged on the vehicle body 101 near the front wheel group 102, and the weight of the cable reel 202 is arranged on the rear wheel group 103 of the vehicle body 101, which to a certain extent prevents the vehicle body 101 from falling backward. In addition, the setting of the traction rope hole 302 can prevent the traction rope from shaking left and right, and to a certain extent, the traction force drives the vehicle body 101 to move in one direction, thereby ensuring the stability of the vehicle body 101.

[0046] The remaining structure is the same as that of Example 2.
