[0002] Cable laying mainly involves laying cables through pre-buried or installed pipeline systems. This method helps protect cables from mechanical damage, corrosion and environmental impacts, and facilitates later maintenance and overhaul. When laying cables, construction pits are usually set up to provide the necessary space and conditions for the installation, maintenance and laying of pipelines and cables.

[0003] However, when the cable is pulled from one section of the drainage pipe through the construction pit into another section of the drainage pipe, since the radius of the traction rope is smaller than the radius of the cable, when the traction force of the traction rope is too large, the cable will be tightened and then deviate upward, resulting in the inability to smoothly enter the other section of the drainage pipe.

By setting the sponge layer, the sponge layer can be squeezed to adapt to the bottom of the inner wall of the row pipe.

[0013] A laying method of a cable laying device for electric power engineering construction comprises the following steps:

[0014] S1: When using this device, first pass the head of the cable through the sleeve rod from the right side to the left side, then rotate the threaded sleeve so that the rising plate clamps the cable, and then the sleeve rod can be fixed on the outer surface of the cable;

[0015] S2: Before the cable enters another section of the pipe from one section, the roller will first contact the inner wall of the construction pit and be squeezed upwards, and finally rotate to the right to limit the cable. At the same time, after the cable and the sleeve rod enter the pipe, the sleeve rod can be supported;

[0016] S3: When the rotating rod three is retracted into the rotating sleeve, it will compress the air in the rotating sleeve. The compressed air will enter the rotating ring and push the sliding rod downward, thereby clearing the sand and stones inside the inner wall of the drainage pipe through the counterweight block and the sponge layer.

[0017] The present invention has the following beneficial effects:

[0018] 1. After the sleeve rod is fixedly installed on the outer surface of the cable, the left side of the cable is connected to the traction rope, and the traction rope is pulled to drive the cable and the sleeve rod to move together. Before the cable enters another section of the pipe from one section of the pipe, the roller will first contact the inner wall of the construction pit. As the cable continues to move with the sleeve rod, the roller will rotate and be squeezed upward, and the roller will drive the rotating rod 1 to rotate through the moving rod and the sliding frame. The rotating rod 1 will drive the rotating rod 3 to rotate through the fixed plate, and the rotating rod 3 will drive the rotating sleeve to rotate. In the above process, the rotating rod 3 will also slide into the interior of the rotating sleeve and compress the spring 2. As the cable continues to move, the rotating rod 1 will drive The movable rod rotates as a whole to the right side of the fixed seat. At this time, the rotating rod will cover the outside of the cable. If the cable deviates upward or downward, the tube will contact the rotating rod when the cable enters the drainage pipe. As the cable continues to move, the drainage pipe will squeeze the rotating rod downward or upward to drive the sleeve rod to move and adjust as a whole, so that the center axis of the cable coincides with the center axis of the drainage pipe, so that the cable can smoothly enter the interior of the drainage pipe. This design can adjust the position of the drainage pipe head before the cable enters the drainage pipe so that it can smoothly enter the interior of the drainage pipe, preventing the left side of the cable from being blocked by the right side of the drainage pipe due to the larger radius of the traction rope after the traction rope enters the drainage pipe.

[0019] 2. The present invention passes the head of the cable through the sleeve rod from the right side of the sleeve rod to the left, and makes the left side of the cable flush with the left side of the gradually rising plate, and then rotates the threaded sleeve. Since the threaded sleeve is threadedly connected to the gradually rising plate, as the threaded sleeve rotates, it will move to the left along the gradually rising plate. When the left side of the threaded sleeve contacts the top of the gradually rising plate, as the threaded sleeve continues to be rotated to move it to the left, the left side of the gradually rising plate will be squeezed by the left side of the threaded sleeve toward the center axis of the threaded sleeve. When the side of several gradually rising plates close to each other contacts the outer surface of the cable, as the gradually rising plates continue to descend, several gradually rising plates will clamp the cable, and then the sleeve rod can be fixed on the outer surface of the cable. This design can clamp the cable so that the sleeve rod can be fixed on the outer surface of the cable to move with it, and can also adapt to cables of different radii within a certain range.

[0020] 3. In the present invention, after the cable and the sleeve rod enter the row pipe, as the cable continues to move, due to the L-shaped design of the moving rod, the roller will be stuck on the right side of the row pipe. The cable continues to move, and the moving rod will drive the sliding frame to pull the spring 1, so that the sliding frame extends from the rotating rod 1. When the sliding frame moves to the final position, as the cable continues to move, the roller will slide into the interior of the row pipe. At this time, the ratchet gear is blocked by the limit rotating rod and cannot move, so the roller cannot move either. The cable continues to move, and the moving rod will always give the sliding frame a pulling force toward the outside of the rotating rod 1 due to the friction between the roller and the inner wall of the row pipe, thereby The movable rod can be moved to the right side of the sleeve rod as a whole, so that the sleeve rod as a whole can be supported before the roller is separated from the inner wall of the drainage pipe, so that it is always in a state of linear motion before it is fully extended out of the drainage pipe. This design can support the sleeve rod through the roller when the sleeve rod is in the drainage pipe, preventing the sand and stones in the drainage pipe from wearing the outer surface of the sleeve rod. At the same time, it can also prevent the top of the sleeve rod from rubbing against the top of the inner wall of the drainage pipe when the cable head is about to be removed from the drainage pipe and the cable is bent and extended upward from the construction pit, because the sleeve rod cannot bend with the cable, thereby damaging both sides.

[0021] 4. When the rotating rod three of the present invention is retracted into the interior of the rotating sleeve, it will compress the air in the rotating sleeve and push the air into the air duct. The air duct will pass the air into the air cavity. The air passed into the air cavity will enter the interior of the rotating ring through the air inlet. The air entering the interior of the rotating ring will push the sliding rod downward. The sliding rod will stretch the spring three and drive the sponge layer to move downward together. The counterweight block will drive the sponge layer to move downward together. By squeezing the sponge layer to make it fit the shape of the bottom of the inner wall of the row pipe, as the cable drives the sleeve rod to move as a whole, the counterweight block and the sponge layer will push the sand and stones that fall on the inner wall of the row pipe. Clean and scrape. In order to prevent the cable from driving the sleeve rod to rotate during the process of moving into the drainage pipe, the rotating ring and the fixed sleeve ring are rotatably connected. In this way, even when the sleeve rod drives the fixed sleeve ring to rotate, the center of gravity of the rotating ring is always on its lower side due to the heavier counterweight. As a result, when the fixed sleeve ring rotates, the rotating ring will also rotate due to the downward center of gravity, so that the counterweight block and the sponge layer are always downward. This design can remove the sand and gravel on the inner wall of the drainage pipe through the action of the counterweight block and the sponge layer, to prevent the surface of the cable from being damaged by sand and gravel when it enters the drainage pipe later.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1 - Figure 3 The present invention is a cable laying device for electric power engineering construction, comprising a fixing assembly 1, the fixing assembly 1 comprising land 100, a construction pit 101 is opened on the top of the land 100, a drainage pipe 102 is fixedly connected to the inner wall of the land 100, and further comprising:

[0036] The limiting assembly 2 includes a fixed seat 201 arranged inside the land 100, the inner wall of the fixed seat 201 is rotatably connected to a rotating rod 202, and the inner wall of the rotating rod 202 is slidably connected to a sliding frame 203;

[0038] A cable 104 is arranged inside the pipe 102, a traction rope 103 is fixedly connected to the left side of the cable 104, a sleeve rod 105 is arranged on the outer surface of the cable 104, a gradually rising plate 106 is fixedly connected to the left side of the sleeve rod 105, and a threaded sleeve 107 is threadedly connected to the outer surface of the gradually rising plate 106. The head of the cable 104 is passed through the sleeve rod 105 from the right side to the left, and the left side of the cable 104 is flush with the left side of the gradually rising plate 106, and then the threaded sleeve 107 is rotated. Since the threaded sleeve 107 is threadedly connected to the gradually rising plate 106, as the threaded sleeve 107 rotates, it will move to the left along the gradually rising plate 106. When the left side of the threaded sleeve 107 is aligned with the gradually rising plate When the top of cable 106 contacts, as the threaded sleeve 107 continues to be rotated to move it to the left, the left side of the gradually rising plate 106 will be squeezed toward the center axis of the threaded sleeve 107 by the left side of the threaded sleeve 107. When the side of several gradually rising plates 106 close to each other contacts the outer surface of cable 104, as the gradually rising plates 106 continue to descend, several gradually rising plates 106 will clamp the cable 104, and then the sleeve rod 105 can be fixed on the outer surface of cable 104. This design can clamp the cable 104 so that the sleeve rod 105 can be fixed on the outer surface of the cable 104 to move with it, and can also adapt to cables 104 with different radii within a certain range.

[0039] For example 2, please refer to Figure 4 - Fig. 9The present invention is a cable laying device for power engineering construction. On the basis of Example 1, there are a plurality of fixing seats 201, and the plurality of fixing seats 201 are fixedly connected to the outer surface of the sleeve rod 105 on the side close to each other. The inner wall of the moving rod 204 is rotatably connected to a roller 205, and the inner wall of the roller 205 is fixedly connected to a rotating shaft 206. The outer surface of the rotating shaft 206 is rotatably connected to the inner wall of the moving rod 204. The outer surface of the rotating shaft 206 is fixedly connected to a ratchet gear 207. The outer surface of the ratchet gear 207 contacts a limited rotating rod 208. When the sleeve rod 10 is moved, the outer surface of the rotating shaft 206 is fixedly connected to the outer surface of the rotating shaft 206. After being fixedly installed on the outer surface of the cable 104, the left side of the cable 104 is connected to the traction rope 103, and the traction rope 103 is pulled to drive the cable 104 and the sleeve rod 105 to move together. Before the cable 104 enters another section of the drainage pipe 102 from one section of the drainage pipe 102, the roller 205 will first contact the inner wall of the construction pit 101. As the cable 104 continues to move with the sleeve rod 105, the roller 205 will rotate and be squeezed upward, and the roller 205 will drive the rotating rod 202 to rotate through the moving rod 204 and the sliding frame 203.

[0040] The inner wall of the limiting rotating rod 208 is fixedly connected with a rotating rod 209, and the outer surface of the rotating rod 209 is rotatably connected to the inner wall of the moving rod 204. The outer surface of the rotating rod 209 is fixedly connected with a coil spring 210, and the coil spring 210 is fixedly connected to the inner wall of the moving rod 204 at the end away from the rotating rod 209. The moving rod 204 is fixedly connected with a shielding shell 211 on the side close to the ratchet gear 207. The right side of the sliding frame 203 is fixedly connected with a spring 1 212, and the right side of the spring 1 212 is fixedly connected to the right side of the inner wall of the rotating rod 1 202.

[0041] A plurality of rotating rods 1 202 are fixedly connected with a fixing plate 213 on a side away from each other, and a rotating rod 3 214 is rotatably connected to an outer surface of the fixing plate 213, and a spring 215 is sleeved on an outer surface of the rotating rod 3 214, and a rotating sleeve 216 is fixedly connected to the right side of the spring 215, and an inner wall of the rotating sleeve 216 is slidably connected to an outer surface of the rotating rod 3 214, and an outer surface of the rotating sleeve 216 is rotatably connected to an inner wall of the sleeve rod 105, and the rotating rod 1 202 will drive the rotating rod 3 214 to rotate through the fixing plate 213, and the rotating rod 3 214 will drive the rotating sleeve 216 to rotate, and in the above process, the rotating rod 3 214 will also slide into the interior of the rotating sleeve 216 and compress the spring 21 5. As the cable 104 continues to move, the rotating rod 202 will drive the moving rod 204 to rotate as a whole to the right side of the fixed seat 201. At this time, the rotating rod 202 will cover the outside of the cable 104. If the cable 104 deviates upward or downward, when the cable 104 enters the row tube 102, the row tube 102 will contact the rotating rod 202. As the cable 104 continues to move, the row tube 102 will squeeze the rotating rod 202 downward or upward to drive the sleeve rod 105 to move and adjust as a whole, thereby making the central axis of the cable 104 coincide with the central axis of the row tube 102, so that the cable 104 can smoothly enter the interior of the row tube 102. This design can adjust the position of the head of the row tube 102 before the cable 104 enters the row tube 102. The cable 104 can smoothly enter the interior of the row tube 102 to prevent the cable 104 from being blocked by the right side of the row tube 102 on the left side due to the larger radius of the cable 104 than the traction rope 103 after the traction rope 103 enters the row tube 102. After the cable 104 and the sleeve rod 105 enter the row tube 102, as the cable 104 continues to move, due to the L-shaped design of the moving rod 204, the roller 205 will be stuck on the right side of the row tube 102, and the cable 104 continues to move. The moving rod 204 will drive the sliding frame 203 to pull the spring 1 212, so that the sliding frame 203 extends out from the rotating rod 1 202. When the sliding frame 203 moves to the final position, as the cable 104 continues to move, the roller 205 will slide into the interior of the row tube 102. At this time, the ratchet gear 207 The cable 104 continues to move, and the movable rod 204 will always give the sliding frame 203 a pulling force toward the outside of the rotating rod 202 due to the friction between the roller 205 and the inner wall of the row tube 102, so that the movable rod 204 can move to the right side of the sleeve rod 105 as a whole, so that before the roller 205 is not separated from the inner wall of the row tube 102, the sleeve rod 105 as a whole can be supported, so that it is always in a state of linear motion before it is fully extended out of the row tube 102. This design allows the sleeve rod 105 to be supported by the roller 205 when it is in the row tube 102, so as to prevent the sand and stones in the row tube 102 from wearing the outer surface of the sleeve rod 105.At the same time, it can also prevent the top of the sleeve rod 105 from rubbing against the top of the inner wall of the pipe 102 when the head of the cable 104 is about to move out of the pipe 102 and the cable 104 is bent and extended upward from the construction pit 101, because the sleeve rod 105 cannot bend along with the cable 104, thereby preventing the top of the sleeve rod 105 from rubbing against the top of the inner wall of the pipe 102, thereby damaging both.

[0042] The air guide tube 301 is fixedly connected to the outer surface of the rotating sleeve 216 at one end away from the fixed ring 302, and the inner wall of the fixed ring 302 is rotatably connected to a rotating ring 304. An air inlet 305 is provided on the left side of the rotating ring 304. A sliding rod 306 is slidably connected to the inner wall of the rotating ring 304, and a counterweight block 307 is fixedly connected to the bottom of the sliding rod 306. When the rotating rod 3214 is retracted into the interior of the rotating sleeve 216, it will compress the air in the rotating sleeve 216 and push the air into the air guide tube 301. The air guide tube 301 will pass the air into the air cavity 303, and the air passed into the air cavity 303 will enter the interior of the rotating ring 304 through the air inlet 305.

[0043] A sponge layer 308 is fixedly connected to the bottom of the counterweight 307, and a spring three 309 is fixedly connected to the top of the sliding rod 306. The spring three 309 is fixedly connected to the top of another sliding rod 306 at the end away from the sliding rod 306. The outer surface of the counterweight 307 is slidably connected to the inner wall of the rotating ring 304, and the outer surface of the sponge layer 308 is slidably connected to the inner wall of the rotating ring 304. The air entering the rotating ring 304 will push the sliding rod 306 downward, and the sliding rod 306 will stretch the spring three 309 and drive the sponge layer 308 to move downward together. The counterweight 307 will drive the sponge layer 308 to move downward together, and the sponge layer 308 will be squeezed to adapt to the shape of the bottom of the inner wall of the row pipe 102. As the cable 104 drives the sleeve rod 105 to move as a whole, the counterweight 307 and the sponge layer 308 will fall on The sand and gravel inside the inner wall of the drainage pipe 102 are cleaned and scraped off. In order to prevent the cable 104 from driving the sleeve rod 105 to rotate when entering the drainage pipe 102 and moving, the rotating ring 304 and the fixed sleeve ring 302 are rotatably connected. In this way, even when the sleeve rod 105 drives the fixed sleeve ring 302 to rotate, due to the heavier counterweight 307, the center of gravity of the rotating ring 304 is always on its lower side, so that when the fixed sleeve ring 302 rotates, the rotating ring 304 will also rotate due to the downward center of gravity, so that the counterweight 307 and the sponge layer 308 are always downward. This design can remove the sand and gravel on the inner wall of the drainage pipe 102 through the action of the counterweight 307 and the sponge layer 308, to prevent the surface of the cable 104 from being damaged by sand and gravel when it enters the drainage pipe 102 later.

[0044] The laying method of the cable laying device comprises the following steps:

[0045] S1: When using the device, first pass the head of the cable 104 through the sleeve rod 105 from the right side to the left, then rotate the threaded sleeve 107 so that the gradually rising plate 106 clamps the cable 104, and then the sleeve rod 105 can be fixed on the outer surface of the cable 104;

[0046] S2: Before the cable 104 enters another section of the pipe 102 from one section, the roller 205 will first contact the inner wall of the construction pit 101 and be squeezed upward, and finally rotate to the right to limit the cable 104. At the same time, after the cable 104 and the sleeve rod 105 enter the pipe 102, the sleeve rod 105 can be supported;

[0047] S3: When the rotating rod 3 214 is retracted into the rotating sleeve 216, it will compress the air in the rotating sleeve 216. The compressed air will enter the rotating ring 304 and push the sliding rod 306 downward, thereby clearing the sand and stones inside the inner wall of the drain pipe 102 through the counterweight block 307 and the sponge layer 308.

[0048] A specific application of this embodiment is:

[0049] When using the device, first pass the head of the cable 104 from the right side of the sleeve rod 105 to the left, and make the left side of the cable 104 flush with the left side of the gradually rising plate 106, then rotate the threaded sleeve 107. Since the threaded sleeve 107 and the gradually rising plate 106 are threadedly connected, as the threaded sleeve 107 rotates, it will move to the left along the gradually rising plate 106. When the left side of the threaded sleeve 107 contacts the top of the gradually rising plate 106, as the threaded sleeve 107 continues to be rotated to move to the left, the left side of the gradually rising plate 106 will be screwed. The left side of the threaded sleeve 107 is squeezed toward the central axis of the threaded sleeve 107. When the side of the plurality of gradually rising plates 106 approaching each other contacts the outer surface of the cable 104, as the gradually rising plates 106 continue to descend, the plurality of gradually rising plates 106 clamp the cable 104, and then the sleeve rod 105 can be fixed on the outer surface of the cable 104. This design can clamp the cable 104 so that the sleeve rod 105 can be fixed on the outer surface of the cable 104 to move with it, and can also adapt to cables 104 with different radii within a certain range.

[0050] After the sleeve rod 105 is fixedly installed on the outer surface of the cable 104, the traction rope 103 is connected to the left side of the cable 104, and the traction rope 103 is pulled to drive the cable 104 and the sleeve rod 105 to move together. Before the cable 104 enters another section of the pipe 102 from one section of the pipe 102, the roller 205 will first contact the inner wall of the construction pit 101. As the cable 104 continues to move with the sleeve rod 105, the roller 205 will rotate and be squeezed upward, and the roller 205 will drive the rotating rod 1 202 to rotate through the moving rod 204 and the sliding frame 203, and the rotating rod 1 202 will drive the rotating rod 3 214 to rotate through the fixed plate 213, and the rotating rod 3 214 will drive the rotating sleeve 216 to rotate. In the above process, the rotating rod 3 214 will also slide into the interior of the rotating sleeve 216 and compress the spring 215. As the cable 104 continues to move, the rotating rod 1 202 will drive The movable rod 204 rotates as a whole to the right side of the fixed seat 201. At this time, the rotating rod 102 will cover the outside of the cable 104. If the cable 104 deviates upward or downward, when the cable 104 enters the row tube 102, the row tube 102 will contact the rotating rod 102. As the cable 104 continues to move, the row tube 102 will squeeze the rotating rod 102 downward or upward to drive the sleeve rod 105 to move and adjust as a whole, thereby making the central axis of the cable 104 coincide with the central axis of the row tube 102, so that the cable 104 can smoothly enter the interior of the row tube 102. This design can adjust the position of the head of the row tube 102 before the cable 104 enters the row tube 102, so that it can smoothly enter the interior of the row tube 102, and prevent the left side of the cable 104 from being blocked by the right side of the row tube 102 because the radius of the cable 104 is larger than that of the traction rope 103 after the traction rope 103 enters the row tube 102.

[0051] After the cable 104 and the sleeve rod 105 enter the row tube 102, as the cable 104 continues to move, due to the L-shaped design of the moving rod 204, the roller 205 will be stuck on the right side of the row tube 102, and the cable 104 continues to move. The moving rod 204 will drive the sliding frame 203 to pull the spring 1 212, so that the sliding frame 203 extends from the rotating rod 1 202. When the sliding frame 203 moves to the final position, as the cable 104 continues to move, the roller 205 will slide into the interior of the row tube 102. At this time, the ratchet gear 207 is blocked by the limiting rotating rod 208 and cannot move, so the roller 205 cannot move either. The cable 104 continues to move, and the moving rod 204 will always give the sliding frame 203 a movement to the outside of the rotating rod 1 202 due to the friction between the roller 205 and the inner wall of the row tube 102. The pulling force causes the moving rod 204 to move to the right side of the sleeve rod 105 as a whole, so that before the roller 205 is not separated from the inner wall of the row pipe 102, the sleeve rod 105 as a whole can be supported all the time, so that it is always in a state of linear motion before it is not fully extended out of the row pipe 102. This design allows the sleeve rod 105 to be supported by the roller 205 when it is in the row pipe 102, preventing the sand and stones in the row pipe 102 from wearing the outer surface of the sleeve rod 105. At the same time, it can also prevent the top of the sleeve rod 105 from rubbing against the top of the inner wall of the row pipe 102 when the head of the cable 104 is about to move out of the row pipe 102 and the cable 104 is bent and extended upward from the construction pit 101, because the sleeve rod 105 cannot bend together with the cable 104, thereby damaging both sides;

[0052] In the above process, when the rotating rod three 214 is retracted into the rotating sleeve 216, it will compress the air in the rotating sleeve 216 and push the air into the air duct 301. The air duct 301 will pass the air into the air cavity 303. The air passed into the air cavity 303 will enter the interior of the rotating ring 304 through the air inlet 305. The air entering the interior of the rotating ring 304 will push the sliding rod 306 downward. The sliding rod 306 will stretch the spring three 309 and drive the sponge layer 308 to move downward together. The counterweight block 307 will drive the sponge layer 308 to move downward together. By squeezing the sponge layer 308 to adapt it to the shape of the bottom of the inner wall of the row pipe 102, as the cable 104 drives the sleeve rod 105 to move as a whole, the counterweight block 307 and the sponge layer 308 will fall into the row pipe 102. The sand and gravel inside the wall are cleaned and scraped off. In order to prevent the cable 104 from driving the sleeve rod 105 to rotate during the movement of the cable 104 into the drainage pipe 102, the rotating ring 304 and the fixed sleeve ring 302 are rotatably connected. In this way, even when the sleeve rod 105 drives the fixed sleeve ring 302 to rotate, due to the heavier counterweight 307, the center of gravity of the rotating ring 304 is always on its lower side, so that when the fixed sleeve ring 302 rotates, the rotating ring 304 will also rotate due to the downward center of gravity, so that the counterweight 307 and the sponge layer 308 are always downward. This design can remove the sand and gravel on the inner wall of the drainage pipe 102 through the action of the counterweight 307 and the sponge layer 308, to prevent the surface of the cable 104 from being damaged by sand and gravel when it enters the drainage pipe 102 later.
