Description

Technical Field

[0001] The invention relates to the technical field of wire and cable laying, and in particular to a long-line power generation 35kV collector wire and cable laying device and a construction method. Background Art

[0002] Cable laying is an important task in power engineering, especially 35kV collector cables, which have higher requirements on construction equipment and technology due to their high voltage level and long transmission distance.

[0003] Referring to the Chinese patent, the application number is "202210533543.4" for the "cable laying vehicle". This patent solves the problem that the cable conveyor will form a certain angle when conveying the cable. Due to the different positions and coils of the cable wound on the cable drum, the angle formed between the cable and the cable conveyor is large. The large angle makes the inside of the cable susceptible to mechanical damage when laying the cable. However, in the laying process of existing wires and cables, due to the long length of the wires and cables, the width of the opened cable trench is often greater than the outer diameter of the cable. If the laid cable cannot be limited and fixed in time after being buried in the cable trench, the cable is prone to bending in the cable trench. The bent cable not only increases the transmission distance of electricity, but also causes cable waste and increases the cost of laying. In addition, during the laying process, the cable is prone to friction with the laying frame, causing wear on the cable. In this regard, we propose a long-line 35kV power generation collector cable laying device and construction method to solve the above problems. Summary of the invention

[0019] Beneficial Effects

[0020] The present invention provides a long-line 35kV power generation cable laying device and construction method. Compared with the prior art, it has the following beneficial effects:

[0021] (1) Through the setting of the scraping and covering limit mechanism, the two curved pipes are moved to both sides by turning the rotating handle, so that the two curved pipes are squeezed into the soil on the side wall of the cable trench. By pulling the entire laying device to move, the curved pipes scrape the soil on the side wall and enter the interior of the curved pipe from one end. After filling, the soil is discharged from the other end. The discharged soil is used to cover the cable to a certain extent, which plays a certain compression and positioning role on the cable, preventing the cable from bending in the cable trench after laying, thereby avoiding the bending of the cable to increase the transmission distance of electricity, and also avoiding the waste of cables and reducing the laying cost.

[0022] (2) Through the setting of the plowing and laying components, the cable is limited by laying rollers so that the cable can always be kept in the center of the cable trench during laying. At the same time, the plowing knife is inserted into the soil to open a placement groove that is better than the cable size. The cable naturally falls into the placement groove during laying, thereby further limiting the cable and preventing the cable from being displaced and bent in the cable trench, greatly improving the cable limiting effect.

[0023] (3) By setting up the oil outlet lubrication component, during the process of unwinding and laying the cable, the movement of the cable is used to naturally drive the two oil outlet cylinders to rotate. When the oil outlet hole of the oil outlet cylinder is aligned with the through hole, the lubricating oil in the oil storage cylinder is discharged onto the cable through the through hole and the oil outlet hole. After the cable is coated with lubricating oil, the friction between the cable and the laying box during transmission is reduced, thereby reducing the wear of the cable during laying and extending the service life of the cable.

[0024] (4) By setting up the automatic soil covering component, when the cable laying is completed, the electric telescopic rod can be started to drive the soil covering plate to move, and the soil dug during trenching can be pushed into the cable trench, realizing the automatic soil covering operation and greatly improving the work efficiency.

[0036] The present invention provides three technical solutions, including the following embodiments:

[0039] The scraping and covering limiting mechanism 5 includes a steering seat 52 rotatably connected to the top of the laying box 4 through a rotating shaft 51, two moving plates 53 are slidably connected to the top of the rotating plate 3, both sides of the top of the steering seat 52 are rotatably connected to a rotating rod 54 through a pin shaft, and the ends of the two rotating rods 54 that are away from each other are rotatably connected to the opposite sides of the two moving plates 53 through a pin shaft, a worm gear 55 is fixed to the top of the rotating shaft 51, a vertical plate 56 is fixed to the top of the laying box 4, and a worm 57 is rotatably connected inside the vertical plate 56, and the worm 57 is meshed with the worm gear 55. The purpose of the setting of the worm gear 55 and the worm gear 57 is to allow only the worm gear 57 to drive the worm gear 55 to rotate, and further drive the two bent pipes 510 to move in reverse, and the two bent pipes 510 are in contact with the cable trench. After contacting the side wall of the movable plate 53, the worm gear 55 will not be driven to rotate under the reaction force. A rotating handle 58 is fixed at one end of the worm 57, and the rotating handle 58 is engraved with anti-slip patterns. A limiting plate 59 is fixed on the top of the rotating plate 3. The limiting plates 59 are located on both sides of the movable plate 53, and one side of the limiting plates 59 is slidably connected to one side of the movable plate 53. The limiting plates 59 are used to limit the movable plate 53 so that the movable plate 53 can always maintain opposite or reverse movement on the rotating plate 3. A bent pipe 510 is fixed on the side away from the two movable plates 53. The bent pipe 510 is "L"-shaped, with open ends. Mud enters from one end and is discharged from the other end. It is used to scrape the mud on the side wall of the cable trench and then cover it on the cable.

[0040] By setting the soil scraping and covering limit mechanism 5, the two curved pipes 510 are moved to both sides by rotating the rotating handle 58, so that the two curved pipes 510 are squeezed into the soil on the side wall of the cable trench, and the entire laying device is pulled to move, so that the curved pipes 510 scrape the soil on the side wall and enter the interior of the curved pipes 510 from one end. After filling, the soil is discharged from the other end, and the discharged soil is used to cover the cable to a certain extent, which plays a certain compression and positioning role on the cable, preventing the cable from bending in the cable trench after laying, thereby avoiding the bent cable to increase the transmission distance of electricity, while also avoiding the waste of cables and reducing the laying cost.

[0041] The installation box 2 is provided with a driving assembly 14 for driving the rotating plate 3 to rotate. The driving assembly 14 includes a driving rod 141 rotatably connected between opposite sides of the two installation boxes 2. One end of the driving rod 141 passes through one of the installation boxes 2 and extends to the outside of the installation box 2.

[0042] A motor 142 is fixed on the top of the installation box 2. The motor 142 is a three-phase asynchronous motor that can be rotated forward and reversely and is electrically connected to the power supply in the installation box 2. A pulley 143 is fixed to the output end of the motor 142 and one end of the driving rod 141. The two pulleys 143 are connected by a belt 144.

[0043] A plowing and laying assembly 6 for limiting the position of the cable and plowing the soil is provided on one side of the rotating plate 3. The plowing and laying assembly 6 includes two horizontal plates 61 fixed on one side of the rotating plate 3. A connecting shaft 62 is rotatably connected between the opposite sides of the two horizontal plates 61. A laying roller 63 is fixed to the outer surface of the connecting shaft 62. The arrangement of the laying roller 63 can limit the cable so that the cable can always be laid in the center of the cable trench during the transmission laying process. L-shaped rods 64 are fixed on the opposite sides of the two horizontal plates 61. Plowing knives 65 are fixed on one side of the two L-shaped rods 64. After the bottom of the plowing knives 65 is inserted into the soil, the soil can be plowed. The two plowing knives 65 are both "Z"-shaped, and one end of the two plowing knives 65 is close to each other, and the other end is far away. The purpose of this arrangement is that after the plowing knives 65 are inserted into the mud, the soil can be pushed to both sides to form a placement groove, and the cable is laid in it, which is conducive to keeping the cable laid in a straight line.

[0044] By setting up the plowing and laying component 6, the laying roller 63 is used to limit the cable, so that the cable can always remain in the center of the cable trench during laying. At the same time, the plowing knife 65 is inserted into the soil to open a placement groove that is better than the size of the cable. The cable naturally falls into the placement groove during laying, thereby further limiting the cable, preventing the cable from being displaced and bent in the cable trench, and greatly improving the cable limiting effect.

[0045] A U-shaped frame 7 is fixed between the tops of the two mounting plates 1, and a cable unwinding mechanism 8 is arranged on one side of the U-shaped frame 7. The cable unwinding mechanism 8 includes two square plates 81 fixed on one side of the U-shaped frame 7, and a winding roller 82 is rotatably connected between the opposite sides of the two square plates 81. A cable is wound and rolled on the winding roller 82. The cable is a 35kV collector cable, which is characterized by a high voltage rating and a long transmission distance. A motor 2 83 is fixed on one side of the square plate 81. The motor 2 83 is a three-phase asynchronous motor that can be rotated forward and reversely and is electrically connected to the internal power supply of the mounting box 2. The motor 2 83 drives the winding roller 82 to rotate.

[0046] A total of four universal wheels 12 are installed at the bottom of the two mounting plates 1, and a handle 13 is fixed to one side of the U-shaped frame 7.

[0047] Example 2

[0048] Based on Example 1, see Figure 6-Figure 9As shown, two limit rollers 9 are rotatably connected between the inner walls of the laying box 4, and the cable passes between the two limit rollers 9 and rolls in contact with the outer surfaces of the two limit rollers 9. The limit rollers 9 can prevent the cable from swinging left and right when the laying box 4 is transmitted. An oil outlet lubrication component 10 is also provided between the inner walls of the laying box 4. The oil outlet lubrication component 10 includes two oil outlet cylinders 101 rotatably connected between the inner walls of the laying box 4. A plurality of oil outlet holes 102 are provided on the two oil outlet cylinders 101. The oil outlet holes 102 are arranged around the outer surface of the oil outlet cylinder 101. Two oil inlet pipes 103 are connected to the top of the laying box 4, and lubricating oil is added from the oil inlet pipes 103.

[0049] The bottom ends of the two oil inlet pipes 103 pass through the laying box 4 and the oil outlet cylinder 101 and extend to the interior of the oil outlet cylinder 101. The bottom ends of the two oil inlet pipes 103 are connected to the oil storage cylinder 104. After the lubricating oil is added from the oil inlet pipe 103, it enters the oil storage cylinder 104 for storage. The outer surfaces of the two oil storage cylinders 104 are penetrated by through holes 105, and the inner surfaces of the two oil outlet cylinders 101 are rotatably connected to the outer surfaces of the oil storage cylinder 104 and the oil inlet pipe 103.

[0050] By setting the oil outlet lubrication component 10, during the process of unwinding and laying the cable, the movement of the cable is used to naturally drive the two oil outlet cylinders 101 to rotate. When the oil outlet hole 102 of the oil outlet cylinder 101 is aligned with the through hole 105, the lubricating oil in the oil storage cylinder 104 is discharged onto the cable through the through hole 105 and the oil outlet hole 102. After the cable is coated with lubricating oil, the friction between the cable and the laying box 4 during transmission is reduced, thereby reducing the wear of the cable during laying and extending the service life of the cable.

[0051] An automatic soil covering component 11 for covering soil is arranged between the tops of the two mounting plates 1. The automatic soil covering component 11 includes a fixing seat 111 fixed on the tops of the two mounting plates 1. An electric telescopic rod 112 is fixed between the opposite sides of the two fixing seats 111. The electric telescopic rod 112 is electrically connected to the power supply inside the mounting box 2, and the two electric telescopic rods 112 are controlled by the same switch. A soil covering plate 113 is fixed to the output ends of the two electric telescopic rods 112. The soil covering plate 113 is in a "Z" shape. When the two electric telescopic rods 112 are started, the soil covering plates 113 are driven to move toward each other, and one side of the soil covering plates 113 is close to each other, and the other side is far away from each other. This shape is conducive to rapid soil covering.

[0052] By setting up the automatic soil covering component 11, when the cable laying is completed, the electric telescopic rod 112 can be started to drive the soil covering plate to move, and the soil dug during trenching can be pushed into the cable trench, thereby realizing automatic soil covering operation and greatly improving work efficiency.

[0053] Example 3

[0054] Based on Example 2, see Figure 1-Figure 9 As shown, the present invention also discloses a construction method for a long-line type power generation 35kV collector cable laying device, which specifically includes the following steps:

[0055] Step 1: Place the entire laying device above the opened cable trench, pass one end of the cable through the laying box 4 and the laying roller 63, start the motor 142, so that the motor 2 83 drives the rotating plate 3 and the laying box 4 to rotate downward and press them into the cable trench, start the motor 2 83, so that the motor 2 83 drives the cable to unwind and lay it;

[0056] Step 2: By rotating the rotating handle 58, the rotating handle 58 drives the worm 57 and the worm wheel 55 to rotate, and the worm wheel 55 further drives the steering seat 52 and the two rotating rods 54 to rotate and spread, so that the two moving plates 53 move back to back, and the two curved pipes 510 are in contact with the soil on the side wall of the cable trench. When the device moves, the curved pipes 510 scrape the soil and discharge it onto the cable to cover it. At the same time, the plow blade 65 is inserted into the soil, and the soil is plowed as the device moves, so that a placement groove is opened in the soil for the cable, which is just used to place the laid cable. The handle 13 is pulled to drive the whole device to move, and the cable is laid while moving;

[0057] Step 3: When the cable moves in the laying box 4, the two oil outlet cylinders 101 are driven to rotate. When the oil outlet hole 102 on the oil outlet cylinder 101 is connected with the through hole 105 on the oil storage cylinder 104, the lubricating oil flows out and flows to the cable surface to be used for lubrication during cable transmission laying to reduce friction.

[0058] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0059] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
