Description

Technical Field

[0001] This application relates to the technical field of cable laying, and in particular to a rapid laying device for buried cables in power construction in extremely cold weather. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals. There are generally four ways to lay cable lines: underground cable laying, duct cable laying, cable trench or tunnel cable laying, and cable tray cable laying. In extremely cold weather, when laying underground cables, it is necessary to first dig a direct burial cable trench, then lay a layer of fine sand and soft soil at the bottom of the trench, and then lay the cable. After the cable is laid, lay another layer of fine sand and soft soil, and finally cover the cable with a layer of bricks or concrete slabs to protect it.

[0003] When laying buried cables, multiple cables are usually laid at once to increase the number of spare cables and reduce the frequency of excavation and maintenance. When buried cables are laid side by side, the distance between the two cables needs to be greater than 100mm to avoid electromagnetic interference and other problems between adjacent cables.

[0004] Regarding the aforementioned technologies, during the laying of buried cables, the cable bending stress during the dragging process can cause the laid cables to bend, which in turn leads to a reduction in the distance between two cables. Summary of the Invention

[0005] In order to reduce the bending caused by the curling stress of the cable, which leads to a reduction in the distance between two cables, this application provides a rapid laying device for buried cables in cold weather power construction.

[0042] 1. While the vehicle body is running, the crushing and grooving components work to dig an installation trench on the fine sand and soft soil cushion layer.

The installation trench limits the two sides of the cable to reduce the bending caused by the curling stress of the cable and prevent the spacing between the two laid cables from changing.

[0043] 2. By controlling the length of the first telescopic rod, the horizontal height of the feed hopper is controlled, and the depth at which the bottom of the feed hopper is embedded in the fine sand and soft soil layer is adjusted, thereby adjusting the excavation depth of the installation trench. By controlling the length of the second telescopic rod, the opening angle of the two slotting plates is adjusted, thereby adjusting the excavation width of the installation trench. Through the adjustment of the excavation depth and width of the installation trench using the slotting assembly, the installation trench can be adapted to cables of different sizes, improving the adaptability of a rapid underground cable laying device for power construction in extremely cold weather.

[0044] 3. Because the fine sand and soft soil layer will harden when laying buried cables in severe cold weather, when using the crushing component, the bottom of the crushing sleeve is first embedded in the fine sand and soft soil layer. At the same time as the grooving component digs the installation groove, the crushing motor is started. The output end of the crushing motor works and drives the second spur gear to rotate. The rotation of the second spur gear drives the first spur gear to rotate. The rotation of the first spur gear drives the crushing sleeve to rotate. The surface of the fine sand and soft soil layer is damaged by the rotation of the crushing sleeve, which reduces the difficulty of grooving the fine sand and soft soil layer by the grooving component.

[0059] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0060] This application discloses a device for rapid laying of buried cables for power construction in extremely cold weather.

[0061] Reference Figures 1 to 3 A rapid underground cable laying device for power construction in extremely cold weather includes a running vehicle body 1, a cable reel laying assembly 2, a heating assembly 3, a grooving assembly 4, and a crushing assembly 5.

[0062] The cable reel unloading assembly 2 is installed on the running vehicle body 1, the heating assembly 3 is connected to the running vehicle body 1, and the grooving assembly 4 and the crushing assembly 5 are both installed on the heating assembly 3.

[0063] When using a rapid underground cable laying device for power construction in severe cold weather, the cable reel is first placed on the cable reel laying assembly 2, and the running vehicle 1 is erected on the direct-buried cable trench. As the running vehicle 1 moves forward, the cable is laid out through the cable reel laying assembly 2. During the laying process, the cable passes through the heating assembly 3, which heats the cable to prevent the cable surface from freezing severely in cold weather, which would increase the bending stress of the cable and affect the normal laying of the cable.

[0064] While the vehicle body 1 is running, the crushing component 5 and the grooving component 4 work to dig an installation groove on the fine sand and soft soil cushion layer, and lay the cable in the installation groove through the cable reel laying component 2. The installation groove limits the two sides of the cable, reduces the bending caused by the cable being affected by the curling stress, and avoids the change in the spacing between the two laid cables.

[0065] Reference Figure 1 and Figure 4 A bracket 11 is fixedly installed on the vehicle body 1. Two symmetrically arranged sliding plates 12 are slidably installed on the bracket 11, and guide wheels 13 are rotatably installed on the sliding plates 12. A double-ended screw 14 is threaded through and rotatably installed on the bracket 11. The threads at both ends of the double-ended screw 14 have opposite directions. The two sliding plates 12 are symmetrically sleeved and threadedly connected to the double-ended screw 14.

[0066] When laying the cable, the cable is threaded between the two guide wheels 13. Then, the double-ended screw 14 is rotated to make the two sliding plates 12 slide on the bracket 11, thereby adjusting the distance between the two guide wheels 13, so that the two guide wheels 13 are in contact with the cable, controlling the cable laying direction and reducing the friction force on the cable during laying.

[0067] Reference Figure 1 and Figure 2 The heating assembly 3 includes a mounting housing 31, a heating sleeve 32, and an electric telescopic rod 33. The fixed end of the electric telescopic rod 33 is fixedly mounted on the vehicle body 1, and the movable end of the electric telescopic rod 33 is fixedly connected to the mounting housing 31. The heating sleeve 32 is inserted through and fixedly mounted on the mounting housing 31, and the heating sleeve 32 can heat the cable inserted inside the heating sleeve 32.

[0068] When laying cables, the length of the electric telescopic rod 33 is adjusted so that the mounting housing 31 can penetrate deep into the direct-buried cable trench and be at a suitable height. The cable is laid in the heating sleeve 32, which heats the cable to reduce the impact of severe cold weather on the surface insulation layer of the cable, restore the flexibility of the cable surface insulation layer, reduce the bending stress of the cable, reduce the bending of the laid cable, and prevent changes in the spacing between two laid cables.

[0069] Reference Figure 3 and Figure 5 The grooving assembly 4 includes a first telescopic rod 41, a feed hopper 42, two grooving plates 43, and a second telescopic rod 44. The fixed end of the first telescopic rod 41 is fixedly mounted on the mounting housing 31, the feed hopper 42 is fixedly mounted on the movable end of the first telescopic rod 41, the two grooving plates 43 are symmetrical and hinged to one end of the opening of the feed hopper 42, and the grooving plates 43 are provided with sliding grooves. The fixed end of the second telescopic rod 44 is fixedly mounted on the feed hopper 42, and the movable end of the second telescopic rod 44 is slidably mounted in the sliding groove.

[0070] When using the slotting assembly 4, the bottom of the feed hopper 42 and the slotting plate 43 are embedded in the fine sand and soft soil layer. The running vehicle 1 drives the installation housing 31 to run, and the installation housing 31 drives the feed hopper 42 and the slotting plate 43 to run, realizing the excavation of the installation slot on the surface of the fine sand and soft soil layer. This makes it convenient to lay the cable in the installation slot. The installation slot limits the two sides of the cable to prevent the spacing between the two laid cables from changing.

[0071] Controlling the length of the first telescopic rod 41 controls the horizontal height of the feed hopper 42, adjusting the depth at which the bottom of the feed hopper 42 is embedded in the fine sand and soft soil layer, thereby adjusting the excavation depth of the installation trench. Controlling the length of the second telescopic rod 44 adjusts the opening angle of the two slotting plates 43, thereby adjusting the excavation width of the installation trench. By adjusting the excavation depth and width of the installation trench through the slotting assembly 4, the installation trench can be adapted to cables of different sizes, improving the adaptability of a rapid underground cable laying device for power construction in cold weather.

[0072] Reference Figure 2 , Figure 3 and Figure 7 The crushing assembly 5 includes a first spur gear 51, a crushing motor 52, a second spur gear 521, a crushing sleeve 53, and a third telescopic rod 54. The first spur gear 51 is rotatably mounted on the mounting housing 31. The fixed end of the crushing motor 52 is fixedly mounted on the mounting housing 31. The second spur gear 521 is coaxially sleeved and fixedly mounted on the output end of the crushing motor 52, and the second spur gear 521 meshes with the first spur gear 51. The crushing sleeve 53 is coaxially mounted on and passes through the first spur gear 51, and the crushing sleeve 53 is slidably connected to the first spur gear 51. The crushing sleeve 53 achieves the slidable connection through a keyway. The sliding direction of the crushing sleeve 53 is parallel to the axial direction of the crushing sleeve 53. The fixed end of the third telescopic rod 54 is fixedly mounted on the mounting housing 31. The third telescopic rod 54 is disposed inside the crushing sleeve 53, and the movable end of the third telescopic rod 54 is rotatably connected to the bottom wall of the crushing sleeve 53.

[0073] Because the fine sand and soft soil layer will harden when laying buried cables in severe cold weather, when using the crushing component 5, the bottom of the crushing sleeve 53 is first embedded in the fine sand and soft soil layer. At the same time as the grooving component 4 digs the installation groove, the crushing motor 52 is started. The output end of the crushing motor 52 works and drives the second spur gear 521 to rotate. The rotation of the second spur gear 521 drives the first spur gear 51 to rotate. The rotation of the first spur gear 51 drives the crushing sleeve 53 to rotate. The surface of the fine sand and soft soil layer is damaged by the rotation of the crushing sleeve 53, reducing the difficulty of grooving the fine sand and soft soil layer by the grooving component 4.

[0074] Adjusting the length of the movable end of the third telescopic rod 54 causes the crushing sleeve 53 to slide on the first spur gear 51, thereby adjusting the depth at which the bottom of the crushing sleeve 53 is embedded in the fine sand and soft soil layer, thus adjusting the excavation depth of the installation groove, enabling the installation groove to adapt to cables of different sizes, and improving the adaptability of a rapid laying device for buried cables in cold weather power construction.

[0075] Reference Figure 7 and Figure 8 The crushing assembly 5 also includes at least one auxiliary crushing plate 55. Two auxiliary crushing plates 55 are symmetrically arranged. The auxiliary crushing plates 55 are inserted through and slidably installed on the side wall of the crushing sleeve 53. The bottom of the auxiliary crushing plate 55 is flush with the bottom of the crushing sleeve 53.

[0076] The crushing assembly 5 also includes an abutment block 541, an abutment rod 542, and a return spring 543. The abutment block 541 is coaxially and fixedly installed on the fixed end of the third telescopic rod 54. The abutment block 541 is frustum-shaped, and the area of ​​the end of the abutment block 541 away from the mounting housing 31 is larger than the area of ​​the end of the abutment block 541 close to the mounting housing 31. One end of the abutment rod 542 is fixedly connected to the auxiliary crushing plate 55, and the other end of the abutment rod 542 abuts against the abutment block 541. One end of the return spring 543 is fixedly connected to the abutment rod 542, and the other end of the return spring 543 is fixedly connected to the crushing sleeve 53. The return spring 543 always applies a force to the abutment rod 542 in the direction close to the abutment block 541. Under the action of the return spring 543, the abutment rod 542 always abuts against the abutment block 541.

[0077] When the length of the movable end of the third telescopic rod 54 is adjusted, the movable end of the third telescopic rod 54 drives the crushing sleeve 53 to move, so that the abutting block 541 and the abutting rod 542 move relative to each other.

[0078] When the movable end of the third telescopic rod 54 extends, the abutment rod 542 moves toward the bottom of the abutment block 541, the distance between the two abutment rods 542 increases, and the abutment rod 542 drives the auxiliary crushing plate 55 to slide away from the third telescopic rod 54, so that the crushing sleeve 53 and the auxiliary crushing plate 55 increase the crushing width of the fine sand and soft soil layer.

[0079] When the movable end of the third telescopic rod 54 shortens accordingly, the abutment rod 542 moves toward the top of the abutment block 541, the distance between the two abutment rods 542 decreases, and the abutment rod 542 drives the auxiliary crushing plate 55 to slide toward the third telescopic rod 54, so that the crushing sleeve 53 and the auxiliary crushing plate 55 reduce the crushing width of the fine sand and soft soil layer.

[0080] The length of the movable end of the third telescopic rod 54 is adjusted, thereby adjusting the depth and width of the installation trench, so that the installation trench can be adapted to cables of different sizes, improving the adaptability of a rapid laying device for buried cables in cold weather power construction.

[0081] Reference Figure 3 , Figure 5 and Figure 6 The cable reel unloading assembly 2 includes a fixed plate 21, a sliding rod 212, a rotating plate 22, and a fourth telescopic rod 24. The fixed plate 21 is fixedly installed on the mounting housing 31 and is coaxially arranged with the heating sleeve 32. At least two slide rails 211 are fixedly installed on the fixed plate 21. There are four slide rails 211, which are evenly arranged on the fixed plate 21 and symmetrically arranged with the axis of the fixed plate 21 as the center. The sliding rod 212 is slidably installed on the slide rail 211. A slider 213 is fixedly installed on the sliding rod 212, and a roller 214 is fixedly installed at one end of the sliding rod 212.

[0082] The rotating disk 22 is coaxially and rotatably mounted on the mounting housing 31. The rotating disk 22 has at least two guide rails 221, and there are four guide rails 221. The four guide rails 221 are evenly arranged on the rotating disk 22 and are symmetrically arranged with the axis of the rotating disk 22 as the center. The guide rails 221 are arc-shaped. The end of the slider 213 away from the slide rail 211 is slidably mounted on the guide rail 221. Both the fixed disk 21 and the rotating disk 22 have wire holes 23, and the wire holes 23 are coaxially arranged with the heating sleeve 32.

[0083] A fourth telescopic rod 24 is fixedly installed inside the slide rail 211. The movable end of the fourth telescopic rod 24 is fixedly connected to the end of the sliding rod 212 away from the roller 214. The rodless cavity at the fixed end of the fourth telescopic rod 24 is filled with hydraulic oil. The rodless cavity at the fixed end of the fourth telescopic rod 24 is connected to the rodless cavities at the fixed ends of the first telescopic rod 41, the second telescopic rod 44, and the third telescopic rod 54. The fourth telescopic rod 24 is connected to the first telescopic rod 41, the second telescopic rod 44, and the third telescopic rod 54 through a bellows. The bellows is extensible in the length direction. Electronic valves are installed at the connections between the fourth telescopic rod 24 and the first telescopic rod 41, the second telescopic rod 44, and the third telescopic rod 54.

[0084] Initially, the four rollers 214 are in contact with each other. When releasing the cable, the cable is threaded through the threading hole 23 and then enters the heating assembly 3. The rotating disk 22 rotates, which in turn drives the guide rail 221 to rotate. The rotation of the guide rail 221 causes the slider 213 to slide within the guide rail 221. As the slider 213 slides, it drives the sliding rod 212 to slide on the guide rail 211. The sliding rod 212 moves towards the fourth telescopic rod 24 until the cable can pass through the threading hole 23 and the rollers 214 abut against the cable. This ensures that the cable is coaxially threaded within the heating sleeve 32, improving the uniformity of heating the cable by the heating sleeve 32.

[0085] As the sliding rod 212 moves away from the fourth telescopic rod 24, it causes the movable end of the fourth telescopic rod 24 to extend. Hydraulic oil in the rodless cavity of the fixed end of the fourth telescopic rod 24 enters the rodless cavities of the fixed ends of the first telescopic rod 41, the second telescopic rod 44, and the third telescopic rod 54, causing the lengths of the first telescopic rod 41, the second telescopic rod 44, and the third telescopic rod 54 to extend accordingly. Then, the electronic valve is closed, fixing the lengths of the first telescopic rod 41, the second telescopic rod 44, the third telescopic rod 54, and the fourth telescopic rod 24, thus improving the structural stability of a rapid underground cable laying device for power construction in extremely cold weather.

[0086] Rotating the rotating disk 22 allows for the adjustment of the length of the fourth telescopic rod 24, ensuring that the length of the fourth telescopic rod 24 matches the cable diameter. This adjustment of the length of the fourth telescopic rod 24 allows for the adjustment of the lengths of the first telescopic rod 41, the second telescopic rod 44, and the third telescopic rod 54, thereby enabling the adjustment of the excavation depth and width of the installation trench. This allows the installation trench to accommodate cables of different sizes, improving the adaptability of a rapid underground cable laying device for power construction in cold weather.

[0087] Reference Figure 1 The cable reel unloading assembly 2 also includes a cable reel frame 25, an unloading shaft 26, and a cable conveyor 27. The cable reel frame 25 is fixedly mounted on the running vehicle body 1, the unloading shaft 26 is rotatably mounted on the cable reel frame 25, and the cable conveyor 27 is fixedly mounted on the end of the mounting housing 31 away from the running vehicle body 1. The cable conveyor 27 is prior art and will not be described in detail here.

[0088] When using the cable reel laying assembly 2, the cable reel is placed on the laying shaft 26, one end of the cable passes through the heating assembly 3 and is installed on the cable conveyor 27. The cable conveyor 27 always pulls the cable so that the cable is laid in the installation groove.

[0089] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
