Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable laying device. Background Art

[0002] In the field of cable laying, direct burial cable laying is widely used due to its low investment, simple construction and excellent heat dissipation conditions. However, in the actual construction process, trench excavation and cable laying face many challenges. Especially when there are stones or hard debris at the bottom of the trench, a certain thickness of soft soil or fine sand must be laid to protect the cable from damage. Although this construction method is suitable for places where there are no obstacles underground and the soil does not contain highly corrosive media, there are still many problems in actual operation.

[0003] Chinese patent CN116435915A discloses an efficient cable laying device, which can effectively improve the efficiency of cable laying, but its use effect will be greatly reduced when the groove is curved or has different depths. Specifically, due to the limited steering ability of the device, it is difficult to achieve flexible steering when encountering a curved groove, which undoubtedly increases the difficulty and uncertainty of construction.

[0004] In addition, there are certain problems with the compaction roller design in the device. Since the height of the compaction roller is fixed, when the excavation depth of the trench changes, the compaction roller may not work properly. For example, in a deeper excavation, the compaction roller may be suspended in the air, and thus cannot effectively compact the soil and fine sand; while in a shallower excavation area, the compaction roller may be unable to move forward because it touches the bottom of the trench, thus hindering the normal operation of the entire device.

The connection between the telescopic rod of the built-in electric cylinder 44 and the lower connecting rod 42 allows the support height to be flexibly adjusted to adapt to different terrains and work requirements.

[0028] The elastic pressing mechanism 5 includes a mounting sleeve 51, a guide rod 52 is slidably fitted in the mounting sleeve 51, a limit plate 53 is provided at the upper end of the guide rod 52, a flexible spring 54 is provided between the limit plate 53 and the mounting sleeve 51, an oblique rod 55 is provided at the lower end of the guide rod 52, and a compacting roller 56 is installed at the end of the oblique rod 55. The sliding fit between the mounting sleeve 51 and the guide rod 52, and the provision of the flexible spring 54, both enable the compacting roller 56 to adjust the compacting force according to actual conditions.

[0029] The flexible spring 54 can drive the limiting plate 53 to approach the mounting sleeve 51 .

[0030] The guide mechanism includes a support plate 61 arranged in the lower box 1, a first shaft 62 and a second shaft 68 are installed on the support plate 61, a left shaft 63 is rotatably connected to the first shaft 62, a front guide wheel 11 is rotatably connected to the left shaft 63, a first rod 64 is fixedly connected to the left shaft 63, a traction rod 65 is rotatably connected to the first rod 64, a second rod 69 is rotatably connected to the end of the traction rod 65, a right shaft 67 is rotatably connected to the second shaft 68, the front guide wheel 11 is rotatably connected to the right shaft 67, the second rod 69 is fixedly connected to the right shaft 67, a telescopic electric cylinder 66 is rotatably connected to the middle of the support plate 61, and the telescopic rod of the telescopic electric cylinder 66 is rotatably connected to the traction rod 65. This design can provide precise guidance in complex environments, greatly improving the accuracy and efficiency of laying.

[0031] The lower box body 1 is provided with through holes for accommodating the left rotating shaft 63 and the right rotating shaft 67 to pass through.

[0032] The front guide wheel 11 is provided with a plurality of anti-slip raised strips 111 .

[0033] A driving motor is provided on the inner wall of the lower box 1, and the output shaft of the driving motor is connected to the rear driving wheel 12; a rotating motor is also provided on the inner wall of the lower box 1, and the output shaft of the rotating motor is connected to a driving gear, and a driven gear is fixedly connected to the cable drum 3, and the driving gear matches the driven gear.

[0034] A sand box 2 is provided on the top of the lower box body 1 , and a discharge passage 21 is opened at the rear side of the sand box 2 .

[0035] Working method: First, according to the needs of cable laying, a trench is excavated on the ground.

Place the cable laying device at the trench, and ensure that the front guide wheel 11 and the rear drive wheel 12 are placed on the ground surface on both sides of the trench. By controlling the extension and contraction of the built-in electric cylinder 44, adjust the height of the support wheel 43 so that it is separated from the bottom of the trench so that the device can move forward smoothly. The rear drive wheel 12 is driven by the drive motor to rotate, so that the laying device moves forward. At the same time, start the rotating motor, and through the cooperation of the driving gear and the driven gear, drive the cable drum 3 to rotate to release the cable. During the forward movement of the device, the compaction roller 56 at the front end of the lower box 1 will compact the soil under the action of the flexible spring 54 to ensure that the cable is stably buried in the soil. When the cable laying is completed, release the valve at the discharge channel 21. Sand falls from the sandbox 2 and covers the cable, providing a layer of protection for the cable.

[0036] When the laying direction needs to be changed, the telescopic electric cylinder 66 in the middle of the support plate 61 is activated. The telescopic rod of the telescopic electric cylinder 66 adjusts the angles of the left rotation shaft 63 and the right rotation shaft 67 through the transmission of the traction rod 65, the first rod 64 and the second rod 69, thereby realizing the deflection of the front guide wheel 11 and completing the steering of the laying device.
