Description

Technical Field

[0001] The invention relates to the field of cable laying, and in particular to a laying mechanism for power cable construction. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. When laying cables, there are several laying methods, such as overhead, low, underwater, wall and tunnel, depending on the application. When constructing surface cables, cables are usually laid using laying devices. However, the existing laying devices have limited automation and usually require multiple workers to assist. The labor cost is high and the laying efficiency is limited. In addition, when the laying device is laying, the cable will first rub against the ground, causing damage to the cable.

[0003] To this end, Chinese patent CN116388063B discloses a cable laying device used in railway power engineering construction, which moves with a moving vehicle body through a traveling device. When the cable drum is laying out the cable, the folding bracket and the clamping mechanism transport the cable in an overhead manner to the traction mechanism at the bottom of the traveling device, so that the traction mechanism follows the traveling device to move on the cable trough when laying out the cable, thereby laying the cable in the cable trough, realizing rapid laying of the cable, avoiding the need to drag the cable for long-distance laying under the traditional laying method, causing wear on the cable surface and the ground, and avoiding the problem of laying the cable in the trough manually after dragging the cable, saving labor costs.

[0004] However, when laying cables over long distances, a pulley for supporting the cables needs to be placed in the cable trough every 10 meters or so to prevent the cables from being damaged by friction with the bottom of the cable trough during the laying process.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] The present invention realizes the function of automatically placing the pulley 321 during the laying of the cable 221 through the frame 1, the winding device 2, the placing device 3, the auxiliary control device 4 and the transmission mechanism 5, so as to achieve the effect of supporting the cable 221 and preventing the cable 221 from being damaged during the laying process, saving a lot of manpower, greatly improving the laying efficiency, and reducing the failure rate of the cable 221, thereby solving the problem that the staff still need to place the pulley 321 to support the cable 221 during the laying process of the cable 221. The frame 1 is provided with a driving device for driving the track wheel 11 to rotate, which is not shown in the figure. The setting of the track wheel 11 enables the laying mechanism to adapt to a variety of paved roads, thereby improving its practicality. When laying the cable 221, the operator first fixes the end of the cable 221 wound on the winding drum 22 at the starting end of the laying of the cable 221, and then drives the track wheel 11 to rotate through the driving device to control the frame 1 to move along the cable trough for accommodating the cable 221. The cable trough is not shown in the figure. As the frame 1 moves, it drives the mounting frame 21 and the winding drum 22 to move, thereby pulling the cable 221 and driving the winding drum 22 to rotate. The winding drum 22 drives the control component 43 through the transmission mechanism 5, and releases the fixing of the locking component 42 to the first bracket 32 ​​located at the notch through the control component 43. The first bracket 32 ​​falls into the cable trough under the action of gravity, thereby supporting the cable 221, preventing the cable 221 from contacting the bottom of the cable trough, and protecting the cable 221.

[0033] Reference Figure 4 and Figure 5: The locking assembly 42 includes a locking block 422 and a first elastic member 423; a locking groove 421 matching the shape of the locking block 422 is provided on the first bracket 32; the locking block 422 is slidably mounted on the guide frame 31, and the control assembly 43 is transmission-connected to the locking block 422; the two ends of the first elastic member 423 are respectively connected to the locking block 422 and the guide frame 31.

The locking block 422 is provided with an arc surface. When laying the cable 221, the operator first fixes the end of the cable 221 wound on the winding drum 22 at the starting end of the laying of the cable 221, and then drives the track wheel 11 to rotate through the driving device to control the frame 1 to move along the cable groove for accommodating the cable 221. As the frame 1 moves, it drives the mounting frame 21 and the winding drum 22 to move, and then pulls the cable 221, driving the winding drum 22 to rotate. The winding drum 22 drives the control component 43 through the transmission mechanism 5. The control component 43 overcomes the elastic force of the first elastic member 423 to control the locking block 422 to move in the direction away from the locking groove 421, so that the locking block 422 is separated from the locking groove 421, and the locking component 42 is released from the first bracket 32 ​​located at the notch. The first bracket 32 ​​is fixed, the first bracket 32 ​​falls into the cable groove under the action of gravity, and then supports the cable 221. The frame 1 continues to move, and the pushing component 41 pushes the first bracket 32 ​​on the guide frame 31 to move, so that the next first bracket 32 ​​moves toward the notch of the guide frame 31. After the first bracket 32 ​​contacts the locking block 422, the locking block 422 is squeezed to overcome the elastic force of the first elastic member 423 to make the locking block 422 shrink. When the first bracket 32 ​​moves to the notch, the locking groove 421 is aligned with the locking block 422. The locking block 422 is stuck in the locking groove 421 under the elastic force of the first elastic member 423, thereby fixing the first bracket 32, so as to facilitate the first bracket 32 ​​and the pulley 321 to be placed again to support the cable 221.

[0049] Reference Figure 3 and Figure 7 A feed box 44 is mounted on the vehicle frame 1 , and a support plate 4131 extending in the horizontal direction is disposed on the top of the mounting plate 413 , and the mounting plate 413 and the support plate 4131 are slidably matched with the feed box 44 .

[0050] The present invention realizes the function of automatic feeding during the laying process through the feeding box 44. Before laying the cable 221, the operator puts multiple first brackets 32 and pulleys 321 into the feeding box 44. During the laying process of the cable 221, as the first brackets 32 and pulleys 321 are placed in the cable trough, the controller sends a signal to the linear driver 411. After receiving the signal, the linear driver 411 drives the push frame 412 to reset. Then, the first bracket 32 ​​in the feeding box 44 falls onto the frame 1 under the action of gravity, and then the linear driver 411 drives the push frame 412 to move toward the notch of the frame 1. The push frame 412 pushes the mounting frame 21 to move through the third elastic member 414, and the mounting frame 21 pushes the first bracket 32 ​​to move into the guide frame 31. At the same time, the first bracket 32 ​​in the guide frame 31 slides in sequence, and then the next first bracket 32 ​​is pushed to the notch of the frame 1, so as to place the first bracket 32 ​​and the pulley 321 again.

[0051] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
