Description

Technical Field

[0001] This utility model relates to the technical field of cable construction equipment for municipal road engineering, specifically to an integrated device for digging, filling, and leading wires for direct-buried cables. Background Technology

[0002] Cable laying is a crucial task in municipal construction. Therefore, the effectiveness and efficiency of cable laying directly impact project efficiency. Current technology typically involves mechanically excavating trenches, followed by manual laying of cables within the trenches, and then burying the trenches using excavating machinery. However, this process involves three steps, with each step requiring completion before the next, which affects construction efficiency and prolongs construction time.

[0003] In addition, the existing patent "An Auxiliary Device for Direct Burial Laying of Power Cables" (Publication No. CN116914632A) belongs to the field of cable laying technology. This device mainly includes a first crossbeam, on which a slide, a rotating frame, and a guide wheel assembly for supporting the cable are mounted. The slide also has a channel for guiding fine sand. Its working principle is to guide the fine sand through the channel, causing it to fall under the cable and preventing the cable's outer surface from being damaged by hard foreign objects in the trench. However, this equipment has a simple design, can only perform the function of laying power cables, and its functionality is relatively limited. Furthermore, the device has high construction costs, slow construction speed, and low construction efficiency. Utility Model Content

This detailed description should not be considered as a limitation of the present invention, but rather as a more detailed description of certain aspects, features, and implementations of the present invention.

[0027] Various improvements and variations can be made to the specific embodiments described in this utility model without departing from the scope or spirit of this utility model, which will be obvious to those skilled in the art. Other embodiments derived from this utility model description will also be obvious to those skilled in the art. This application specification and embodiments are merely exemplary.

[0028] This utility model provides an integrated device for digging, filling, and leading wires for direct-buried cables, such as... Figure 1 The diagram shows the overall structure of the device. In a specific embodiment, the device includes: a fixed frame 1, with a traction mechanism 2 for connecting to the traction device fixedly mounted on the front side of the fixed frame 1. Typically, the traction device is connected to a traction connector at the rear of the tractor vehicle, which then drives the device forward.

[0030] The bottom of the fixed frame 1 is equipped with multiple rollers 8 for movement.

[0031] The landfill mechanism 6 is located at the disassembly position of the plow mechanism 3 and is used to fill the trench.

[0032] Typically, a tractor unit connected to a traction mechanism drives the entire device to move and lift. During this forward movement, the plow mechanism 3 excavates a trench, the cable clamping mechanism 4 pulls the cable forward in the trench, and the cable pressing mechanism 5 presses the cable in the trench. Finally, the plow mechanism 2 is removed and replaced with a burial mechanism 6. The tractor unit pulls the device forward from the starting point of the trench.

In this embodiment, the burial operation is performed from one end of the trench after trenching and cable laying to ensure the quality of cable laying and to prevent damage to the cable sheath from the overlying soil during laying. Additionally, avoiding backfilling during cable laying reduces the resistance to cable pulling and prevents cable breakage during the pulling process.

[0045] Specifically, when it is necessary to clamp the cable, press down on the outer end of the cable clamp 43, such as... Figure 4 As shown. Then, insert the cable through the insertion end of the cable clamp 42, with the cable end passing through the clamping channel of the cable clamp and finally extending from the fixed end of the cable clamp 42. Finally, release the cable clamp 43; the spring 44 pushes the cable clamp 43 upward, securing the cable, as shown. Figure 5As shown.

[0046] In specific embodiments of this utility model, such as Figure 6 As shown, the pressing mechanism 5 includes a second fixed rod 51 and a pressing roller 52. The second fixed rod 51 is vertically fixed downwards on the fourth transverse fixed beam 12 along the forward direction of the device.

[0047] The fourth transverse fixing beam 12 has multiple connecting holes evenly arranged in the transverse direction for adjusting the position of the second fixing rod 51 in the transverse direction. In this embodiment, the connecting holes on the transverse fixing beam 12 are fixedly connected to the adapter fixing block 13 for conversion, and the second fixing rod 51 is fixedly connected to the transverse fixing beam 12 through the adapter fixing block 13.

[0048] The second fixing rod 51 has multiple connecting holes evenly arranged in the vertical direction. The fixing component fixes the second fixing rod 51 to the adapter fixing block 13 through these connecting holes, which is used to adjust the distance between the bottom end of the second fixing rod 51 and the transverse fixing beam 12. The cable pressing mechanism 5 has a lifting and adjusting function, which can be adjusted up and down according to the trench depth to adjust the depth of cable pressing, so as to press the cable tightly in the trench and ensure the quality of cable laying.

[0049] The pressure roller 52 is fixedly mounted at the bottom of the second fixed rod 51 to press the cable into the groove. In a specific embodiment, the pressure roller 52 includes a supporting round rod and a round tube sleeved on the supporting round rod that can rotate around the supporting round rod. The two pressure rollers 52 are arranged in an inverted V shape at the bottom of the second fixed rod 51, with the joint ends of the two pressure rollers facing the forward direction, and the two pressure rollers are arranged parallel to the ground.

[0050] In specific embodiments of this utility model, such as Figure 7 As shown, the landfill mechanism 6 includes a third fixing rod 61 and a backfill shovel 62. The third fixing rod 61 is vertically downwardly positioned on the second transverse fixing beam 12 at the location where the first fixing rod 31 is removed.

[0051] The second transverse fixing beam 12 has multiple connecting holes evenly arranged in the transverse direction for adjusting the position of the third fixing rod 61 in the transverse direction.

The landfill mechanism 6 has a lifting adjustment function, which can control the thickness of the backfill and ensure the quality of the backfill.

[0053] The backfill shovel 62 is fixedly mounted at the bottom of the third fixing rod 61 and is used to backfill soil into the trench. In this embodiment, the backfill shovel 62 has a V-shaped structure with its opening facing the direction of device movement, and is used to trap soil into the trench.

[0054] The implementation process of this utility model is as follows: First, the plow mechanism 3 excavates a trench in front, and the cable clamping mechanism 4 clamps and pulls the cable forward in the trench. During the laying process of the cable in the trench, the pressing mechanism 5 at the rear presses the cable downwards into the trench to prevent it from falling outside the trench and affecting subsequent backfilling. When the trench is excavated and the cable is laid in the trench, the plow mechanism 3 is disassembled and the backfilling mechanism 6 is replaced in the same position. Then, it moves from one end of the trench to the other. During the movement, the backfilling mechanism 6 fills the trench with soil, and the pressing mechanism at the rear compacts the soil to ensure the backfilling effect.

[0055] In a specific embodiment of this utility model, a counterweight box 7 for adding weight is fixedly installed on the fixed frame 1. The counterweight box is fixedly connected to the longitudinal fixed beam 11 through a fixed connection port on the counterweight box.
