Description

Technical Field

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

[0002] Cables are one of the most commonly used and important components in power engineering. They can be divided into many types based on their usage environment, such as transmission cables and communication cables. Some of these cables are installed overhead, while others are installed on the ground or underground. Cables installed on the ground or underground are usually installed in pipes, such as cement pipes and PVC pipes, to protect the cables. However, during the cable installation process, the cables may fall into the pipes and be dragged forward. This not only increases the frictional resistance of the traction, but also causes cable wear. The adverse effects of friction are particularly noticeable for long-distance cable installations.

[0003] There are also methods of setting up fulcrums to support cables during construction, or adding rollers to reduce friction. However, it is not easy to set up fulcrums and rollers in the pipeline, and a large number of fulcrums and rollers need to be installed manually, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic laying device for power engineering cables in view of the problems existing in the prior art.

[0005] To achieve the above object, the technical solution adopted by the present invention is: The cable is then pulled out of the rigging machine and the cable is then pulled into position by the guide rails, and the guide rails are moved in a direction that the guide rails are pulled out of the rigging machine, so that the cable can be laid in a horizontal direction.

[0006] The automatic cable laying equipment for electric power engineering projects arranges a number of movable supporting components at intervals on the cable, and then pulls the cable into the pipeline, so that the cable can be supported in the pipeline, avoiding direct friction between the cable and the pipeline, reducing friction, making the cable move more smoothly, and avoiding friction damage to the cable, with very little wear and tear. The effect is particularly obvious for long-distance laying, effectively protecting the cable, and improving the service life and safety of the cable.

[0007] For longer pipelines, more movable supporting components need to be set at intervals. If manual installation is adopted, it is not only time-consuming and labor-intensive, but also difficult to control the spacing between the two movable supporting components. The present invention arranges the pushing component on the laying platform, and can use the pushing component to automatically buckle the movable supporting component under the cable, thereby reducing the amount of manual labor and also realizing the control of the installation spacing by controlling the speed and interval time.

[0008] Furthermore, the first and second brackets are both elevating brackets, with the first horizontally movable module mounted on a lifting platform. Braked wheels are also provided at the bottom of the first bracket to facilitate movement between the cable reel and the second bracket. This elevating arrangement allows for adjustable cable support height, facilitating cable connection with pipes in different locations while also accommodating different cable reel models, enhancing the device's applicability and adaptability.

[0009] Furthermore, the pushing assembly includes a pushing base plate mounted on the first horizontally movable module, the pushing base plate being provided with an electric push rod, the electric push rod being provided with a pushing intermediate plate, a plurality of guide rods being provided between the pushing intermediate plate and the pushing base plate, and a pair of support plates being provided on the pushing intermediate plate, the pair of support plates being spaced apart, the support plates being provided with support grooves for supporting the movable supporting assembly. The movable supporting assembly is lifted up in an instant and quickly snapped onto the cable at a speed very high relative to the travel speed of the cable, allowing the movable supporting assembly to be quickly connected and installed while the cable is in motion.

[0010] Furthermore, the laying platform is also provided with a pair of liftable columns, the multi-directional movable module includes a second horizontal movable module connected between the pair of liftable columns, a movable third horizontal movable module is provided below the second horizontal movable module, and a clamping claw assembly is provided below the third horizontal movable module; the second horizontal movable module is arranged parallel to the first horizontal movable module and across the top of the cable, and the third horizontal movable module is arranged perpendicular to the second horizontal movable module.

[0011] Furthermore, the clamping jaw assembly is connected to the bottom of the third horizontal movable module through an electric boom, or is installed under the third horizontal movable module through a robotic arm; the clamping jaw assembly includes a clamping jaw electric cylinder connected to the electric boom or robotic arm, and a clamping jaw arranged on the clamping jaw electric cylinder.

[0012] Furthermore, auxiliary tool boxes are provided on both sides of the length direction of the first horizontal movable module on the laying platform, and a plurality of the movable supporting components are neatly and orderly placed in the auxiliary tool boxes.

[0013] Furthermore, the movable support assembly includes a support base plate, an adaptive support plate disposed above the support base plate, movable wheels or universal balls disposed below the support base plate, and connecting rods disposed on both sides of the support base plate, the connecting rods being used to support the push assembly. When the push intermediate plate and the support plate are lifted, the connecting rods will also move upward synchronously, causing the adaptive support plate to move upward and automatically engage the cable, thereby completing the automated installation of the movable support assembly.

[0014] Furthermore, the adaptive supporting plate includes an arc-shaped arm arranged on the supporting base plate, and the free ends of the arc-shaped arm are respectively provided with guide arms folded outward. In a natural state, the minimum spacing between the guide arm and the arc-shaped arm at the transition point is less than the inner diameter of the arc-shaped arm; metal springs are also provided in the guide arm and the arc-shaped arm.

[0015] Furthermore, a guide chute is provided in the pipeline along the laying direction, and a detachable docking slide is also provided at the end of the pipeline.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," etc., etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0021] like Figure 1 indivual Figure 2As shown, an automatic laying device for power engineering cables includes a laying platform 1, on which a cable drum 2 is provided, on which a cable 3 to be laid is wound, and on the side of the laying platform 1 away from the cable drum 2, a first bracket 5 and a second bracket 7 are sequentially provided, the first bracket 5 is provided with a pressure roller 6, and the second bracket 7 is provided with a pair of guide rollers 8. The cable 3 is horizontally led out via the pressure roller 6 and the guide roller 8, and then is pulled into the pipe 4 to be laid by a traction member, and a plurality of movable support groups are arranged at intervals below the cable 3. Part 9; the laying platform 1 is provided with a first horizontal movable module 10 near the second bracket 7, the first horizontal movable module 10 is located below the cable 3 and is arranged perpendicular to the travel direction of the cable 3, and the first horizontal movable module 10 is provided with a pushing component 11, and the pushing component 11 is used to install the movable supporting component 9 below the cable 3; the laying platform 1 is also provided with a multi-directional movable module 12, and the multi-directional movable module 12 controls the clamping claw component to pick up the movable supporting component 9 and place it on the pushing component 11.

[0022] The automatic cable laying equipment for electric power engineering arranges a number of movable supporting components 9 at intervals on the cable, and then pulls the cable 3 into the pipeline, so that the cable 3 can be supported in the pipeline, avoiding direct friction between the cable and the pipeline, and the friction force is smaller, making the cable movement smoother, and also avoiding friction damage to the cable, with very little wear and tear, especially for long-distance laying, the effect is more obvious, effectively protecting the cable, and improving the service life and safety of the cable.

[0023] The coordinated arrangement of the first bracket 5 and the pressure roller 6 can apply downward pressure to the cable 3. Since the cable pulled out from the cable drum with a larger diameter has a higher starting height, it is difficult to turn the cable to a horizontal position at a close distance. By pressing the cable downward by the pressure roller, the cable can be pressed down faster and closer, and at the same time the cable can be tensioned to prevent it from becoming loose, which is conducive to the cable passing smoothly through the pair of guide rollers.

[0024] The second bracket 7 and the guide roller 8 can guide the cable 3 to pass through horizontally therebetween. The purpose of making the cable 3 horizontal is to facilitate the installation of the movable support assembly 9 below the cable, and also to facilitate the cable to enter the pipe 4. The traction member is a component that pulls the cable through the pipe. The traction member can be a pipe robot. The cable is connected to the pipe robot, and the pipe robot leads the cable to the other end of the pipe. The traction member can also be an existing original cable. When repairing and replacing an existing cable, a new cable can be connected to the original cable. When the original cable is pulled out at the other end of the pipe and reeled up, the new cable will be introduced into the pipe synchronously. In actual construction, other types of driving members in the existing technology can also be used to drive the cable to move in the pipe.

[0025] The movable supporting assembly 9 is installed under the cable before the cable enters the pipeline. Figure 5 and Figure 6 As shown, the movable supporting assembly 9 is supported on the inner wall of the pipe 4 and moves along the inner wall of the pipe under traction, so as to prevent the cable 3 from falling on the inner wall of the pipe 4 and being dragged forward, thereby avoiding wear of the cable.

[0026] When the cable is pulled into place and laid, the cable will relax by itself under the action of its own weight because it is not affected by the traction force. Figure 7 As shown, the movable support assembly 9 moves slightly, and the cable is supported on the inner wall of the pipe instead of being fully supported by the movable support assembly 9. This situation is allowed and has no adverse effect on the laid cables. It also prevents the movable support assembly 9 from being subjected to long-term continuous stress. When the cables need to be maintained, connected, or even upgraded later, the movable support assembly 9 can still be used to support the cables by pulling them. These movable support assemblies 9 can also be recycled and reused when the cables are replaced later, so they will not be wasted.

[0027] For longer pipes 4, more movable support assemblies 9 need to be set at intervals. If manual installation is adopted, it is not only time-consuming and labor-intensive, but also difficult to control the spacing between the two movable support assemblies. The present invention sets the pushing assembly 11 on the laying platform, and can use the pushing assembly 11 to automatically buckle the movable support assembly 9 under the cable 3, thereby reducing the amount of manual labor, and can also control the installation spacing by controlling the speed and interval time. The pushing assembly 11 is set on the first horizontal movable module 10, which can drive the pushing assembly 11 to move, making it convenient for the pushing assembly 11 to receive incoming materials, that is, the movable support assembly transferred from the multi-directional movable module 12. The multi-directional movable module 12 can move freely in multiple directions above the first horizontal movable module 10, so as to accurately transfer the movable support assembly 9 to the pushing assembly 11, and can also pick up the movable support assembly to be installed from the auxiliary tool box 17.

[0028] Furthermore, the first bracket 5 and the second bracket 7 are respectively liftable brackets, such as brackets made of electric telescopic rods, and the first horizontal moving module 10 is arranged on the lifting platform 15. Through this liftable setting, the support height of the cable 3 can be adjusted. On the one hand, it is beneficial for the cable 3 to be connected with pipes at different positions. On the other hand, it can also adapt to different types of cable reels, thereby improving the scope of application and adaptability of the equipment.

[0029] The bottom of the first bracket 5 is also provided with a moving wheel with a brake to move between the cable drum 2 and the second bracket 7. After the cable is gradually released from the cable drum, the number of turns gradually decreases, and the starting point of the cable lead-out will gradually decrease. The first bracket 5 can adapt well to the change in cable height through horizontal movement and lifting adjustment, and can always press the cable tightly and adjust the direction and tightness of the cable.

[0030] The moving wheel may be driven by a motor, or an electric slider may be provided at the bottom of the first bracket, and a slide rail may be provided on the laying platform, so that the electric slider moves on the slide rail to drive the first bracket to move.

[0031] In some embodiments, the distance between the pair of guide rollers 8 is adjustable so that they can adapt to cables of various sizes.

[0032] Further, combined Figure 3 and Figure 4As shown, the pushing assembly 11 includes a pushing base plate 1101 installed on the first horizontal moving module 10, an electric push rod 1103 is provided on the pushing base plate 1101, a pushing intermediate plate 1102 is provided on the electric push rod 1103, a plurality of guide rods 1104 are provided between the pushing intermediate plate 1102 and the pushing base plate 1101, a pair of support plates 1105 are provided on the pushing intermediate plate 1102, the pair of support plates 1105 are arranged at intervals, and a support groove 1106 is provided on the support plate 1105, and the support groove 1106 is used to support the movable supporting assembly 9.

[0033] By installing the electric push rod 1103 on the pushing base plate 1101, the pushing middle plate 1102 can be driven to move up and down, thereby driving the movable supporting assembly 9 supported by it to move up and down. When the movable supporting assembly 9 follows the pushing assembly 11 to move directly below the cable, the electric push rod 1103 pushes the pushing middle plate 1102 upward, and then pushes the movable supporting assembly 9 upward, allowing the movable supporting assembly 9 to automatically engage with the cable 3 to complete the connection and installation of the movable supporting assembly.

[0034] The plurality of guide rods 1104 can play a guiding role and can also improve the stability of the pushing intermediate plate jacking; the pair of support plates 1105 can respectively support the movable support assembly, and the clamped movable support assembly can be directly placed on the support groove of the support plate. The movable support assembly 9 is located in the area between the pair of support plates 1105. After the movable support assembly is lifted up to complete the installation, the support plate is lowered to complete the separation of the two. The movable support assembly then follows the cable and enters the pipeline. The movable support assembly 9 is lifted up in an instant and quickly clipped onto the cable 3. The speed is very fast relative to the travel speed of the cable 3. The movable support assembly 9 can be quickly connected and installed during the movement of the cable 3.

[0035] The support groove 1106 is an open groove with its opening facing upward, which can conveniently accommodate the connecting rods 905 on both sides of the movable supporting assembly 9 to form a structure that supports the movable supporting assembly.

[0036] Furthermore, the laying platform 1 is provided with a pair of liftable columns 16, and the multi-directional movable module 12 includes a second horizontal movable module 1201 connected between the pair of liftable columns 16, and a movable third horizontal movable module 1202 is provided below the second horizontal movable module 1201, and a clamping claw assembly 13 is provided below the third horizontal movable module 1202; the second horizontal movable module 1201 is arranged parallel to the first horizontal movable module 10 and across the top of the cable, and the third horizontal movable module 1202 is arranged perpendicular to the second horizontal movable module 1201.

[0037] A pair of liftable columns 16 can not only support the multi-directional movable module 12, but also adjust the height of the multi-directional movable module 12 as a whole; the second horizontal movable module 1201 can drive the third horizontal movable module 1202 to move in the space above the cable, and the third horizontal movable module 1202 can drive the lower clamping assembly 13 to move in the other direction of the horizontal plane. Through the above arrangement, the clamping assembly 13 can be moved in the three directions of XYZ, with a wider range of movement, and can more conveniently pick up and transfer the movable supporting assembly.

[0038] The first horizontal moving module 10, the second horizontal moving module 1201 and the third horizontal moving module 1202 can all be commercially available mature products, equipped with various servo drive motors and position sensors. These servo drive motors and position sensors are also electrically connected to the main controller of the entire equipment. The setting of the position sensor facilitates their movement to the planned position.

[0039] Furthermore, the clamping assembly 13 is connected to the bottom of the third horizontal moving module 1202 through an electric boom, or is installed under the third horizontal moving module 1202 through a robotic arm; the clamping assembly includes a clamping electric cylinder connected to the electric boom or robotic arm, and a clamp arranged on the clamping electric cylinder.

[0040] By connecting and installing the clamping assembly through the electric boom and the robotic arm, the flexibility and operability of the clamping assembly 13 can be further improved, so that it can better reach into the auxiliary tool box to grab the movable support assembly without frequently lifting and lowering the entire multi-directional movable module; the clamping assembly 13 is an electric clamping assembly that can clamp or grab the connecting rods on both sides of the movable support assembly.

[0041] Furthermore, the laying platform 1 is provided with auxiliary tool boxes 17 on both sides of the length direction of the first horizontal movable module 10, and a number of the movable supporting components 9 are neatly and orderly placed in the auxiliary tool box 17 so that the clamping claw component 13 can pick up the movable supporting components 9 accurately and orderly.

[0042] Furthermore, the movable supporting assembly 9 includes a supporting base plate 901, an adaptive supporting card plate 902 is provided above the supporting base plate 901, and a moving wheel 903 or a universal ball 904 (such as Figure 9 As shown), connecting rods 905 are respectively provided on both sides of the supporting base plate 901, and the connecting rods 905 are used to be supported on the pushing component 11 or grasped by the clamping claw component 13.

[0043] The supporting base plate is set up, on the one hand, for connecting the wheel frame or universal ball seat below so as to install the moving wheel or universal ball; on the other hand, an adaptive supporting card plate can be set up above it, and the adaptive supporting card plate can be used to connect and support the cables; the connecting rods can also be set up on both sides thereof.

[0044] A pair of connecting rods are supported in the support grooves on the support plate. When the pushing intermediate plate and the support plate are lifted up, the connecting rods will also move upward synchronously, causing the adaptive support card to move upward and automatically snap into the cable, thereby completing the automated installation of the movable support assembly.

[0045] Further, combined Figure 8 As shown, the adaptive supporting card plate 902 includes an arc-shaped card arm 9021 arranged on the supporting base plate 901, and the free ends of the arc-shaped card arm 9021 are respectively provided with outward-folded guide arms 9022. In the natural state, the minimum distance between the guide arm 9022 and the arc-shaped card arm 9021 at the transition point is less than the inner diameter of the arc-shaped card arm 9021; metal springs 9023 are also provided in the guide arm 9022 and the arc-shaped card arm 9021.

[0046] The arc-shaped clamping arm 9021 and the guide arm 9022 are an integrated structure with a certain elasticity and can provide a certain clamping force. When they are clamped on the cable 3, they can properly clamp the cable 3. The arc-shaped clamping arm 9021 plays a supporting role while playing a clamping role. The appropriate clamping force allows the movable support assembly to be suspended below the cable and can move with the cable into the pipeline. The distance from being clamped to moving into the pipeline is short, and the adaptive support card 902 will not loosen or detach from the cable 3. When it enters the pipeline, the moving wheel or universal ball will support the inner wall of the pipeline. At this time, the adaptive support card 902 will support the cable 3 to prevent the cable 3 from directly contacting the inner wall of the pipeline 4, so as to prevent the cable from being damaged by friction due to continuous dragging on the inner wall during the traction movement.

[0047] The pair of guide arms 9022 are folded outward to facilitate cable insertion. The diameter of the transition is smaller than the cable's outer diameter, allowing them to clamp the cable after insertion. The curved arms are appropriately long along the cable's length, providing effective local support. The metal springs 9023 enhance the strength and elasticity of the adaptive support plate. These springs can be made of spring steel or a memory alloy.

[0048] In some embodiments, a guide slot 18 is provided in the pipeline 4 along the laying direction, and a detachable docking slide 14 is also provided at the end of the pipeline 4 .

[0049] The setting of the guide groove 18 can play a guiding and limiting role. When the cable is introduced into the pipeline, the moving wheel or the universal ball will fall on the guide groove so that it can move in a certain direction. Using the universal ball for movement will have better flexibility, especially at the bends of the pipeline, the universal ball can pass more smoothly.

[0050] The docking slide 14 is a guide slide provided to facilitate the movable supporting assembly to enter the pipeline. The movable supporting assembly is suspended below the cable, and its lowest point may be lower than the lowest point of the pipeline. The arrangement of the docking slide facilitates the smooth sliding of the movable wheel or universal wheel into the pipeline.

[0051] Furthermore, the laying platform 1 is also provided with a control box and a power supply, and the control box is provided with a main controller, and the power supply can supply power to the control box and the above-mentioned related components that use electricity; a length counting sensor is also provided on one side of the second bracket, and the length counting sensor is arranged toward the cable led out from a pair of guide rollers, and can measure the running length of the cable, and arrange the movable supporting assembly according to the length value, for example, a movable supporting assembly is arranged every 1-2m, or 3-5m, or 8-10m. The specific value of the interval is determined comprehensively according to factors such as the total laying length, the type and weight of the cable, etc. After determination, the preset value can be written into the main controller. When the length value detected by the length counting sensor reaches the preset value, the main controller gives an instruction to let the pushing assembly push the movable supporting assembly into the cable; within the time period of the interval arrangement, the pushing assembly can accept a new movable supporting assembly again and prepare to push it in.

[0052] If the cable travels at a relatively steady speed, the interval can also be determined by the time the cable moves, and a push instruction is given at a fixed interval to allow the movable supporting assembly to be connected to the cable at the time interval.

[0053] To this end, the present invention also provides a method for installing the movable supporting assembly, which is as follows: When the speed of the cable is stable (no obvious fluctuations, able to maintain a constant speed), the cable moving speed is recorded as V, and a movable supporting component is set at a preset distance of L, then the time interval Δt is L / V, and the main controller will issue an instruction every Δt time interval to allow the pushing component to complete a push-in installation operation of the movable supporting component.

[0054] When the speed of the cable is not steady (there are many unexpected factors in actual on-site construction, which may cause the cable to not be laid at a constant speed all the time), the length counting sensor monitors the length S of the cable passing through a pair of guide rollers. When the length S is close to or equal to the preset interval L, the main controller directly issues a command to the pushing component to complete a push-in installation operation of the movable supporting component. Example 2

[0055] This embodiment provides another structure of a movable supporting assembly, which can simultaneously introduce multiple cables into a pipeline and support the multiple cables at the same time.

[0056] Specifically, such as Figure 10 and Figure 11 As shown, multiple groups of cable drums 2 are arranged on the laying platform 1 at the same time. Multiple cables 3 are guided by multiple guide rollers and led to the top of the pushing assembly 11 at the same time. Multiple cables 3 are connected to the movable supporting assembly 9. The movable supporting assembly 9 has multiple supporting base plates 901 arranged side by side. Each supporting base plate 901 is provided with an adaptive supporting card plate 902 above it, and each supporting base plate 901 is provided with a moving wheel or a universal ball below it. Adjacent supporting base plates 901 are connected by connecting rods 905. Connecting rods 905 are also provided on the outer sides of the supporting base plates at both ends. Through such an arrangement, multiple adaptive supporting cards can be clamped into cables at the same time, supporting the laying of multiple cables in the pipeline at the same time.

[0057] For the movable support assembly 9 for laying multiple cables 3, the pushing assembly 11 can use the structure of Example 1 for support and pushing. Alternatively, it can be appropriately improved by increasing the number of support plates 1105 to support not only the connecting rods on both sides but also the connecting rods between adjacent support base plates. This can provide a more stable pushing and clamping effect for the cables. The pipe is provided with a support plane inside to simultaneously support multiple movable support assemblies.

[0058] In some embodiments, as Figure 12As shown, the adjacent supporting base plates 901 are connected by a rotatable and bendable connecting rod 19. A hinge is provided in the middle of the connecting rod 19, which can be folded upward. After multiple adaptive supporting plates 902 are inserted into multiple cables 3, the cables 3 are pulled upward on both sides when entering the pipeline 4, so that the adaptive supporting plates 902 on both sides are turned vertically. In this way, three cables can be introduced into the original circular pipeline at the same time, and the laying of multiple cables can be completed at the same time.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
