Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to a cable laying device and a laying method for electric power engineering construction. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application occasion, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying method is very important to ensure the transmission quality, reliability and construction and maintenance of the line.

[0003] Chinese patent CN118198936A discloses a cable tray multi-cable laying auxiliary device and a cable laying method, which fixes the cables by placing the cables to be installed in a horizontal row under the beam, using bolts and nuts to fix the U-shaped clips on the lower surface of the beam, and using walking wheels to drive the bracket to walk on the cable tray, thereby achieving the purpose of pulling multiple cables at the same time.

[0004] When the above-mentioned cable laying device is in use, since the vehicle-mounted crossbeam is located in the bottom of the groove of the bridge frame, when cables need to be installed, workers need to use U-shaped clips to fix all cables that need to be installed. The line of sight is blocked by the crossbeam under the vehicle, and the cables are easily not installed tightly, causing the cables to fall off during the laying process. It also increases the time required for cable installation, causing workers to bow their heads for a long time to install the cables. Maintaining the same posture for a long time may cause physical fatigue and affect work efficiency. Summary of the invention

[0025] 2. The clamping plate is pressed down to drive the driving gear 1 and the driving gear 2 on both sides to rotate in the storage cavity opened on the clamping plate, so that the rotating rod drives the stabilizing clamping plate 1 and the stabilizing clamping plate 2 to rotate from the placement grooves on both sides to clamp the cables in the cable release channel, which can ensure that the cables maintain the correct position after installation, prevent the cables from moving due to external force or self-weight, and avoid cross arrangement.

[0026] 3. When the locking wheels 1 and 2 rotate in the rotating groove, the ratchets on the inner ring will be driven to rotate along the sleeved fixed cylinder, and the inclined surface of the ratchets will pass along the arc surface of the stop block, which can prevent the cable from falling off due to movement or vibration, thereby improving the overall electrical safety. The characteristics of easy installation and adjustment make the wiring work more convenient and flexible, and improve the work efficiency of wiring.

[0027] 4. By pushing the pull plate on one side of the clamping seat and the clamping plate, the movable slide in the clamping seat and the clamping plate is driven to slide through the movable column, so that the L slide bar in the movable groove slides from the sliding through hole along the sliding track away from the oblique cone column, and the one-way limit of all cables on the clamping seat and the clamping plate is cancelled. When the cables need to reach the laying point or the equipment needs to be maintained, all cables can be quickly released, which can greatly improve work efficiency and improve the flexibility and adaptability of the equipment.

[0043] A cable anti-slip mechanism 300 is provided between the clamping seat 201 and the clamping plate 202. The cable anti-slip mechanism 300 includes a plurality of locking wheels 1 302 and locking wheels 2 303 respectively provided in the clamping seat 201 and the clamping plate 202 in correspondence with each other. The clamping seat 201 and the clamping plate 202 are both provided with a rotating slot 301 capable of placing the locking wheels 1 302 and the locking wheels 2 303 for rotation. The cable will slide along the wire-releasing slot 203 and pass between the locking wheels 1 302 and the locking wheels 2 303. The locking wheels 1 302 and the locking wheels 2 303 will rotate along the cable insertion direction to lock the cable against slipping.

[0044] A squeezing moving block 205 is provided below the clamping plate 202, and a lifting rack 206 is fixedly installed on the upper surface of the squeezing moving block 205. A driving gear 1 207 and a driving gear 2 208 are respectively meshed on both sides of the lifting rack 206. The driving gear 1 207 and the driving gear 2 208 are both rotatably connected in the clamping plate 202. One side of the driving gear 1 207 and the driving gear 2 208 are both fixedly connected with a rotating rod 209. A stabilizing clamp 1 210 and a stabilizing clamp 2 211 are respectively fixedly installed on the surface of the rotating rod 209 near both ends. The stabilizing clamp 1 210 and the stabilizing clamp 2 211 on both sides of the wire-releasing groove 203 can clamp and stabilize cables of different sizes.

[0045] Specifically, the locking wheel 1 302 and the locking wheel 2 303 are both located between the two rotating rods 209, and are both located between the stabilizing clamping plate 1 210 and the stabilizing clamping plate 211;

[0046] By inserting the cable into the wire-releasing groove 203 between the clamping seat 201 and the clamping plate 202, the cable will pass between the locking wheel 1 302 and the locking wheel 2 303 during the insertion process along the wire-releasing groove 203, and the surface of the cable will contact the locking wheel 1 302 and the locking wheel 2 303 corresponding to the upper and lower parts, driving the locking wheel 1 302 and the locking wheel 2 303 to rotate in the rotating groove 301 in the direction of cable insertion, thereby The cables between 202 are locked to prevent them from falling off, and one end of the clamping plate 202 is pulled by the output end of the cylinder 204 to rotate and press down around the top of the limit plate, driving the driving gear 1 207 and the driving gear 2 208 engaged with the lifting rack 206 to descend, so that the driving gear 1 207 and the driving gear 2 208 are rotated, and the rotating rod 209 simultaneously drives the stabilizing clamp 1 210 and the stabilizing clamp 2 211 on both sides of the wire-releasing groove 203 to rotate to clamp the cables on the left and right.

[0047] By inserting the cable into the cable anti-slip mechanism 300 in the cable release groove 203, the locking wheel 1 302 and the locking wheel 2 303 will fit and contact the surface of the cable, and the cable is only allowed to be inserted between the locking wheel 1 302 and the locking wheel 2 303, which can ensure the stability of the cable during the installation and use process, reduce safety accidents caused by cable falling off, facilitate rapid installation of cables, reduce the time of manual handling and adjustment of cables, and improve construction efficiency. The output end of the cylinder 204 pulls the clamping plate 202 to rotate and press down along the limit plate at one end, so that the driving gear 1 207 and the driving gear 2 208 are lowered and rotated, and the rotating rod 209 drives the stabilizing clamping plate 1 210 and the stabilizing clamping plate 211 on both sides of the cable release groove 203 to rotate to clamp the cable. By pressing down and clamping left and right, it can be ensured that the cable is fixed in three dimensions, which can provide a more stable clamping effect, can adapt to cables of different sizes and shapes, and increase the use efficiency of the equipment.

[0048] Example 2

[0049] Reference Figure 3-Figure 5 , which is the second embodiment of the present invention, provides a cable laying device, wherein placement grooves 212 are respectively opened on the clamping plate 202 at positions corresponding to the stabilizing clamping plate 1 210 and the stabilizing clamping plate 211, and a storage cavity 213 is opened in the clamping plate 202, and the driving gear 1 207 and the driving gear 2 208 are both rotatably connected in the storage cavity 213, and the shape of the placement grooves 212 is consistent with the shape of the stabilizing clamping plate 1 210 and the stabilizing clamping plate 211, and are symmetrically opened on both sides of the wire laying channel 203.

[0050] Limiting grooves 214 are provided on both sides of the lifting rack 206, and a limiting slider 215 is fixedly connected in the storage cavity 213. The limiting slider 215 is slidably connected in the limiting groove 214. A return spring 216 is arranged between the lifting rack 206 and the clamping plate 202. The limiting slider 215 is fixedly connected to the positions of the limiting grooves 214 on both sides of the storage cavity 213 to prevent the lifting rack 206 from falling off from the storage cavity 213. Two return springs 216 are sleeved on the upper surface of the lifting rack 206, and the other end of the return spring 216 is connected to the clamping plate 202.

[0051] Specifically, before the downward pressure begins, the clamping plate 202 is still at the highest point, and the top of the lifting rack 206 is flush with the driving gear 1 207 and the driving gear 2 208 on both sides in the storage chamber 213, and remains stationary. When the cylinder 204 begins to pull the clamping plate 202 downward, the clamping plate 202 drives the lifting rack 206 to descend together through the return spring 216, so that the lifting rack 206, the driving gear 1 207 and the driving gear 2 208 in the storage chamber 213 move downward as a whole. When the extrusion moving block 205 at the bottom end of the lifting rack 206 contacts the upper surface of the clamping seat 201, as the clamping plate 202 continues to descend, the lifting rack 206 remains at the original height, and the clamping plate 202 Then, the driving gear 1 207 and the driving gear 2 208 in the storage chamber 213 will be driven to move downward along the two sides of the lifting rack 206, squeezing the return spring 216 at the top of the rotating rod 209. During the movement, the meshing driving gear 1 207 and the driving gear 2 208 will rotate in the storage chamber 213, so that the rotating rod 209 drives the stabilizing clamping plate 1 210 and the stabilizing clamping plate 211 to rotate from the placement grooves 212 on both sides to clamp the cables in 203. When clamping cables of different diameters, the cylinder 204 drives the clamping plate 202 to press down to different heights. When the stabilizing clamping plate 1 210 and the stabilizing clamping plate 211 rotate to be in close contact with the surface of the cable, the clamping plate 202 stops pressing down.

[0052] On the contrary, when it is necessary to cancel the clamping of the cable, the cylinders 204 on both sides push the clamping plate 202. When the clamping plate 202 rotates along the limit plate and gradually lifts, the reset spring 216 first gradually stretches and resets, and the extrusion moving block 205 and the lifting rack 206 remain at their original height. The clamping plate 202 drives the driving gear 1 207 and the driving gear 2 208 in the storage cavity 213 to gradually rise along the lifting rack 206, and drives the stabilizing clamp plate 1 210 and the stabilizing clamp plate 2 211 on both sides to gradually rotate and be recovered into the placement groove 212 through the rotating rod 209. After the reset spring 216 is completely reset, when the clamping plate 202 continues to rise, it will drive the extrusion moving block 205 and the lifting rack 206 to rise synchronously through the reset spring 216, and the lifting rack 206, the driving gear 1 207 and the driving gear 2 208 move upward as a whole.

[0053] Example 3

[0054] Reference Figure 1 , Figure 7-Figure 9 , which is the third embodiment of the present invention, provides a cable laying device, each rotating slot 301 is fixedly connected with a fixed cylinder 304, a sliding hole 305 is opened in the fixed cylinder 304, an inclined cone column 306 is longitudinally slidably connected in the sliding hole 305, the sliding hole 305 is inverted T shape, and the bottom end of the inclined cone column 306 is an inclined surface.

[0055] A lifting groove 307 is provided at the top of the oblique cone column 306, and a limiting column 308 is slidably connected in the lifting groove 307. A blocking block 309 is fixedly connected to the top of the limiting column 308. The lifting groove 307 is convex, and an anti-slip plate is fixedly connected to the bottom of the limiting column 308. The anti-slip plate is slidably installed at the lower part of the convex lifting groove 307.

[0056] An annular spring piece 310 is arranged between the inclined cone column 306 and the stop block 309, and the annular spring piece 310 is sleeved on the outside of the limiting column 308. The inner circles of the locking wheel 1 302 and the locking wheel 2 303 are surrounded by ratchet teeth 311. The ratchet teeth 311 are only provided with an inclined surface on one side, and the other side is a vertical surface. The locking wheels 1 302 and the locking wheels 303 are both surrounded by arc-shaped circular grooves 312.

[0057] The outer rings of the locking wheel 1 302 and the locking wheel 2 303 are surrounded by anti-skid pads 313, and an L slide bar 314 is horizontally slidably connected in the sliding through hole 305. The clamping seat 201 and the clamping plate 202 are respectively provided with movable grooves 315 for the L slide bar 314 to slide, and the anti-skid pad 313 is connected to the surface of the locking wheel 1 302 and the locking wheel 2 303 along the arc-shaped circular groove 312.

[0058] A pull plate 319 is provided on the outer side of the clamping seat 201 and the clamping plate 202, and a plurality of movable columns 318 are fixedly connected to the side of the pull plate 319. The ends of the movable columns 318 are respectively fixedly connected to movable slides 316. Each movable slide 316 and movable column 318 can slide inside the clamping seat 201 and the clamping plate 202 respectively. A sliding track 317 is provided on the surface of the movable slide 316. An inclined surface is provided at one end of the L slide rod 314 located inside the sliding through hole 305, and the other end is slidably inserted into the sliding track 317.

[0059] The sliding track 317 includes two parallel tracks and an inclined track for connecting the two parallel tracks. When the bottom end of the L sliding rod 314 is located in the parallel track close to the pull plate 319, the inclined surface of the L sliding rod 314 is in contact with the inclined surface of the inclined cone column 306, and the ratchet 311 will never contact the stop block 309; when the bottom end of the L sliding rod 314 is located in the parallel track away from the pull plate 319, the circumferential surface of the L sliding rod 314 is in contact with the bottom end of the inclined cone column 306. During the rotation of the ratchet 311 around the fixed cylinder 304, the top end of the stop block 309 can move along the inclined surface of the ratchet 311 under the elastic force of the annular spring sheet 310 to achieve one-way limiting.

[0060] Initially, the bottom end of the L slide bar 314 is located in the parallel track close to the pull plate 319. When the locking wheel 1 302 and the locking wheel 2 303 are needed to clamp and limit the cable, the two pull plates 319 on the outside of the clamping seat 201 and the clamping plate 202 are pulled. The pull plates 319 synchronously pull the movable slide plates 316 through the movable column 318, so that the bottom end of the L slide bar 314 slides into the inclined track and then enters the parallel track away from the pull plate 319. During this process, the L slide bar 314 gradually approaches the inclined cone column 306 and pushes the inclined cone column 306 upward until the circumferential surface of the L slide bar 314 contacts the bottom end of the inclined cone column 306. When the cable passes between the locking wheel 1 302 and the locking wheel 2 303, the surface of the cable will fit with the arc-shaped circular groove 312. The anti-skid pad 313 provided on the surface of the locking wheel 1 302 and the locking wheel 2 303 drives the locking wheel 1 302 and the locking wheel 2 303 to rotate in the direction of inserting the cable while the cable is inserted. When the locking wheel 1 302 and the locking wheel 2 303 rotate in the rotating groove 301, the ratchet teeth 311 on the inner ring are driven to rotate along the sleeved fixed cylinder 304. The inclined surface of the ratchet teeth 311 passes along the arc surface of the stop block 309, and squeezes the annular spring piece 310 under the stop block 309, so that the stop block 309 descends and drives the limiting column 308 to slide in the lifting groove 307. When the ratchet teeth 311 pass through, the compressed annular spring piece 310 pushes the stop block 309 to rise again to limit the ratchet teeth 311 in one direction.

[0061] Furthermore, when the cable needs to cancel the anti-slip lock between the locking wheel 1 302 and the locking wheel 2 303, the pull plate 319 on one side of the clamping seat 201 and the clamping plate 202 is pushed at the same time, and the pull plate 319 synchronously pushes each movable slide plate 316 through the moving column 318, so that the bottom end of the L slide bar 314 slides into the inclined track and then enters the parallel track close to the pull plate 319, restoring the initial state, and the ratchet 311 will never come into contact with the stop block 309, canceling the one-way limit of all cables on the clamping seat 201 and the clamping plate 202, so that the cables can be smoothly detached and removed from between the locking wheel 1 302 and the locking wheel 2 303.

[0062] Example 4

[0063] Reference Figure 1-Figure 4 , Figure 6 , which is a fourth embodiment of the present invention, provides a laying method for electric power engineering construction, using the above-mentioned cable laying device, comprising the following steps:

[0064] First, insert the cable into the wire-releasing groove 203 between the clamping seat 201 and the clamping plate 202. During the insertion of the cable along the wire-releasing groove 203, the cable will pass between the locking wheel 1 302 and the locking wheel 2 303. The surface of the cable will contact the corresponding locking wheel 1 302 and the locking wheel 2 303 above and below, driving the locking wheel 1 302 and the locking wheel 2 303 to rotate in the rotating groove 301 in the direction of cable insertion, thereby preventing the cable inserted between the clamping seat 201 and the clamping plate 202 from falling off and locking.

[0065] The output end of the cylinder 204 is used to pull one end of the clamping plate 202 to rotate and press down along the limit plate, driving the driving gear 1 207 and the driving gear 2 208 meshing with the lifting rack 206 to descend, so that the driving gear 1 207 and the driving gear 2 208 rotate, and the rotating rod 209 simultaneously drives the stabilizing clamping plate 1 210 and the stabilizing clamping plate 2 211 on both sides of the wire-releasing groove 203 to rotate to clamp the cable on the left and right.
