Description

Technical Field

[0001] This invention relates to a cable laying technology, specifically a cable trench laying device and a cable trench laying construction method. Background Technology

[0002] Cable trenches are specialized underground channels used for laying cables, and their applications are becoming increasingly widespread. Cable supports are fixed within the trenches, and the cables need to be neatly stacked on supports of varying heights for easy classification, isolation, and later maintenance. Laying cables in cable trenches requires a large number of personnel, who manually pull the cables through the trench. However, due to the limited space within the trench, especially in enclosed trenches, the movement of construction workers is restricted, resulting in low laying efficiency. Cables are easily worn down during the pulling process. Because of the corners in the trench, cables are more prone to friction with the trench walls when being pulled through corners, leading to damage. Furthermore, cable laying is carried out after the cable supports are installed, and contact and friction between the supports and cables can easily occur, causing damage to either the cable or the cable supports. Summary of the Invention

[0003] The purpose of this invention is to provide a cable trench laying device and a cable trench laying construction method to solve the problems of the existing cable trench laying process requiring a large amount of manpower, low efficiency, and easy damage to cables.

[0004] The present invention is implemented as follows: a cable trench cable laying device includes a base, a hidden universal wheel mechanism is provided at the four corners of the base, a plurality of lifting mechanisms are provided on the base, a support plate is provided on the lifting mechanism, a horizontal main conveying roller is provided on the upper surface of the support plate, and a vertical side conveying roller is provided at both ends of the main conveying roller. The main conveying roller and the two side conveying rollers form a conveying groove for conveying cables, and the side conveying rollers are mounted on a swing bracket.

[0005] The end of the swing bracket is hinged to the support plate. The swing plane of the swing bracket is perpendicular to the axis of the main conveying roller. A limit plate is provided on one side of the swing bracket. When the swing bracket is in a vertical state, the limit plate of the swing bracket contacts and restricts the swing bracket from swinging further toward the limit plate.

[0006] The concealed caster wheel mechanism includes a pressing block disposed on the lower surface of the support plate, a concealed cylinder disposed on the base, a connecting block passing through the concealed cylinder, and a caster wheel disposed at the bottom of the connecting block. The caster wheel at the bottom of the connecting block is pushed out of the lower surface of the base by inserting the pressing block into the concealed cylinder.

[0007] The lifting mechanism includes a first support rod and a second support rod arranged in a cross pattern. A rotating shaft passes through the middle of both the first support rod and the second support rod. The upper end of the first support rod and the lower end of the second support rod are respectively hinged to the support plate and the base. The lower end of the first support rod and the upper end of the second support rod are respectively hinged to a first slider and a second slider. The first slider is slidably mounted on the base, and the second slider is slidably mounted on the support plate. A lead screw is provided on the support plate, passing through the second slider and threadedly connected to it. A handwheel is provided at the end of the lead screw.

[0008] The main conveying roller and the side conveying roller are both uniform straight rods in the middle, and the radii at both ends gradually increase to form limiting parts, and the limiting parts of the main conveying roller and the side conveying roller are adjacent to each other.

[0009] A method for laying cables in a cable trench includes the following steps.

[0010] a. A cable trench laying device is arranged at intervals in the cable trench. The cable trench laying device includes a base, with hidden universal wheel mechanisms at the four corners of the base, and several lifting mechanisms on the base. Support plates are provided on the lifting mechanisms, and a horizontal main conveying roller is provided on the upper surface of the support plate. Vertical side conveying rollers are provided at both ends of the main conveying roller. The main conveying roller and the two side conveying rollers form a conveying groove for conveying cables. The side conveying rollers are mounted on a swing bracket.

[0011] b. After determining the location of the cable trench laying device, hide the casters of the concealed caster mechanism so that the base plate sits on the bottom surface of the cable trench.

[0012] c. Arrange cable reels at the entrance end of the cable trench and a winding device at the exit end of the cable trench.

[0013] d. Pass the wire rope wound on the winding device through the cable trench and connect it to the end of the cable on the cable reel, and place the wire rope in the conveying groove of the cable laying device in the cable trench.

[0014] e. Start the winding device to wind up the wire rope and cable, and pull the wire rope and cable along the cable trench until the cable is completely through the cable trench.

[0015] f. Control the height of the support plate through the lifting mechanism to make the height of the cable and the height of the cable bracket consistent. Move the swing bracket to flatten the vertical side conveying roller, lift the cable on the cable trench laying device to the cable bracket, and disconnect the ends of the wire rope and cable.

[0016] g. Repeat steps d to f until all cables in the cable trench have been laid. Finally, remove the cable laying device, cable reel, and winding device from the cable trench.

[0017] Based on the number and type of cables placed on each layer of cable support in the design scheme, one or more cables are pulled using a winding device each time, and the cables are placed on the corresponding cable support.

[0018] At least one cable laying device for the cable trench is placed at the corner of the cable trench.

[0019] The concealed caster mechanism includes a pressing block disposed on the lower surface of the support plate, a concealed cylinder on the base, a connecting block passing through the concealed cylinder, and a caster wheel disposed at the bottom of the connecting block. When moving and adjusting the position of the cable trench laying device, the pressing block is inserted into the concealed cylinder to push the caster wheel at the bottom of the connecting block out of the lower surface of the base. After the position of the cable trench laying device is determined, the support plate is raised to a certain height, the caster wheel retracts into the concealed cylinder, and the base contacts the ground.

[0020] The lifting mechanism includes a first support rod and a second support rod arranged in a cross pattern. A rotating shaft passes through the middle of both the first support rod and the second support rod. The upper end of the first support rod and the lower end of the second support rod are respectively hinged to the support plate and the base. The lower end of the first support rod and the upper end of the second support rod are respectively hinged to a first slider and a second slider. The first slider is slidably mounted on the base, and the second slider is slidably mounted on the support plate. A lead screw is provided on the support plate, passing through the second slider and threadedly connected to it. A handwheel is provided at the end of the lead screw.

[0021] The cable trench laying device of this invention can quickly transport cables, allowing them to pass through rapidly. The main conveying roller and side conveying rollers reduce friction with the cable during movement. At the corners of the cable trench, the cable is deflected to one side under the action of traction, and the deflected cable contacts the side conveying roller, preventing the cable from falling off the cable trench laying device and ensuring that the friction force on the cable is minimal. The concealed caster mechanism allows the casters to extend and retract. When the casters are extended, the cable trench laying device can move flexibly; when the casters are retracted, the base rests on the ground, stably positioning the cable trench laying device in the predetermined position. The lifting mechanism can adjust the height of the cable, and the side conveying rollers can be laid flat, facilitating the horizontal movement of the cable onto the cable support.

[0022] The cable trench laying method of the present invention uses the above-mentioned cable trench laying device. The cable trench laying device is arranged in the cable trench at a certain interval. When the wire rope is wound by the winding device, the cable moves in the conveying groove formed by the main conveying roller and the side conveying roller. Since the main conveying roller and the side conveying roller can rotate, the friction with the cable is reduced, so that the cable can pass through the cable trench smoothly. At the same time, at the corner, the position of the cable is restricted by the side conveying roller to prevent the cable from falling out. Thus, the cable will not come into contact with the ground, side walls, corners or cable supports in the cable trench and generate friction, avoiding damage to the cable and cable supports during the laying process and improving the laying efficiency.

[0023] This invention can improve the efficiency of cable laying in cable trenches, reduce the number of construction personnel required for cable laying, and avoid damage to cables and cable supports during the cable laying process. Attached Figure Description

[0029] like Figure 1 , Figure 2 As shown, the cable trench cable laying device 14 of the present invention includes a base 1, with hidden universal wheel 2 mechanisms provided at the four corners of the base 1, a plurality of lifting mechanisms 3 provided on the base 1, a support plate 4 provided on the lifting mechanism 3, a horizontal main conveying roller 5 provided on the upper surface of the support plate 4, and vertical side conveying rollers 6 provided at both ends of the main conveying roller 5. The main conveying roller 5 and the two side conveying rollers 6 form a conveying groove for conveying the cable 12, and the side conveying rollers 6 are mounted on a swing bracket 7.

[0030] The cable trench laying device 14 can be moved flexibly when needed by the hidden universal wheel 2 mechanism. When the position needs to be fixed, the base 1 sits on the ground and the movement of the cable trench laying device 14 is prevented by the friction with the ground. The height of the support plate 4 is controlled by the lifting mechanism 3, and the cable 12 is placed in the conveying groove. In the straight section, the cable 12 contacts the main conveying roller 5 and the main conveying roller 5 rotates with the movement of the cable 12. At the corner, the cable 12 contacts the side conveying roller 6 under the action of tension and the side conveying roller 6 rotates with the movement of the cable 12. The rotation of the main conveying roller 5 and the side conveying roller 6 reduces the friction force on the cable 12 during the forward movement.

[0031] The side conveyor roller 6 is mounted on the swing bracket 7, the lower end of which is hinged to the support plate 4. The swing plane of the swing bracket 7 is perpendicular to the axis of the main conveyor roller 5, allowing the side conveyor roller 6 to lie flat in a plane perpendicular to the axis of the main conveyor roller 5. Simultaneously, a limit plate 8 is provided on one side of the swing bracket 7. When the swing bracket 7 is in a vertical state, the limit plate 8 contacts the swing bracket 7, thus restricting the swing bracket 7 from swinging further towards the limit plate 8. That is, the swing bracket 7 can only swing within a 90° range, achieving either a flat or vertical position. During use, the side with the limit plate 8 is adjusted to face forward in the direction of travel. The swing bracket 7, driven by the cable, rests against the limit plate 8. After the cable 12 passes through the cable trench 9, the swing bracket 7 is laid flat, facilitating the movement of the cable 12 onto the cable bracket 10.

[0032] The concealed caster wheel mechanism 2 includes a pressing block fixed to the lower surface of the support plate 4. A concealed cylinder is provided on the upper surface of the base 1, and a through hole passes through both the concealed cylinder and the base 1. A connecting block is provided inside the through hole, which can move up and down within the through hole. A caster wheel is provided at the bottom of the connecting block. When the pressing block is inserted into the concealed cylinder, it presses the connecting block downward, pushing the caster wheel out of the lower surface of the base 1. When the pressing block moves out of the concealed cylinder, the connecting block retracts into the concealed cylinder under the action of gravity, and the base 1 contacts the ground. The pressing block is fixed to the support plate 4, and the relative displacement between the support plate 4 and the base 1 is achieved by a lifting mechanism 3.

[0033] The lifting mechanism 3 enables the support plate 4 to move up and down. In this embodiment, the lifting mechanism 3 uses a scissor brace and includes a first and second support rod arranged in a cross pattern. The rotating shaft passes through the middle of both the first and second support rods. The upper end of the first support rod and the lower end of the second support rod are respectively hinged to the support plate 4 and the base 1. The lower end of the first support rod and the upper end of the second support rod are respectively hinged to the first and second sliders. Slide grooves are provided on the base 1 and the support plate 4, and the first and second sliders are respectively installed in the slide grooves on the base 1 and the support plate 4, allowing them to slide on the base 1 and the support plate 4. A lead screw is provided on the support plate 4, passing through the second slider and threadedly connected to it. A handwheel is provided at the end of the lead screw. Rotation of the lead screw drives the movement of the second slider, causing the first and second support rods to swing, thereby changing the relative distance between the support plate 4 and the base 1.

[0034] Both the main conveyor roller 5 and the side conveyor roller 6 have uniform straight rods in the middle, with the radii gradually increasing at both ends to form limiting parts. The limiting parts of the main conveyor roller 5 and the side conveyor roller 6 are adjacent to each other. During conveying, the cable 12 is generally located in the straight rod section of the main conveyor roller 5. When passing through a corner, the cable 12 moves towards the inside of the corner, and contacts the limiting parts of the main conveyor roller 5 and the side conveyor roller 6, and is prevented from coming off by the limiting part at the upper end of the side conveyor roller 6.

[0035] The cable trench cable laying device 14 can quickly transport the cable 12, allowing the cable 12 to pass quickly through the cable trench 9. The main conveying roller 5 and the side conveying roller 6 can reduce the friction on the cable 12 during movement. At the corner of the cable trench 9, the cable 12 is deflected to one side under the action of traction force. The deflected cable 12 contacts the side conveying roller 6, preventing the cable 12 from falling off the cable trench cable laying device 14 and ensuring that the friction force on the cable 12 is very small.

[0036] The concealed caster wheel 2 mechanism has casters that can extend and retract. When the casters are extended, the cable trench cable laying device 14 can move flexibly. When the casters are retracted, the base 1 rests on the ground, so that the cable trench cable laying device 14 is stably placed in the predetermined position. The lifting mechanism 3 can adjust the height of the cable 12, and the side conveying roller 6 can be laid flat, which facilitates the horizontal movement of the cable 12 onto the cable bracket 10.

[0037] like Figure 3 , Figure 4 As shown, the cable trench 9 cable laying construction method of the present invention includes the following steps.

[0038] a. A cable trench laying device 14 is arranged at intervals in the cable trench 9. The cable trench laying device 14 includes a base 1, a hidden universal wheel mechanism 2 is provided at the four corners of the base 1, a number of lifting mechanisms 3 are provided on the base 1, a support plate 4 is provided on the lifting mechanism 3, a horizontal main conveying roller 5 is provided on the upper surface of the support plate 4, and a vertical side conveying roller 6 is provided at both ends of the main conveying roller 5. The main conveying roller 5 and the two side conveying rollers 6 form a conveying groove for conveying the cable 12. The side conveying rollers 6 are mounted on the swing bracket 7.

[0039] b. After determining the position of the cable trench cable laying device 14, hide the casters of the concealed caster 2 mechanism so that the base plate sits on the bottom surface of the cable trench 9.

[0040] c. A cable reel 11 is arranged at the entrance end of the cable trench 9, and a winding device 13 is arranged at the exit end of the cable trench 9.

[0041] d. Connect the wire rope wound on the winding device 13 through the cable trench 9 and the end of the cable 12 on the cable reel 11, and place the wire rope in the conveying groove of the cable laying device 14 in the cable trench.

[0042] e. Start the winding device 13 to wind up the wire rope, pulling the steel wire rope and cable 12 forward along the cable trench 9 until the cable 12 has completely passed through the cable trench 9.

[0043] f. Control the height of the support plate 4 through the lifting mechanism 3 so that the height of the cable 12 is consistent with the height of the cable bracket 10. Move the swing bracket 7 to flatten the vertical side conveying roller 6, lift the cable 12 on the cable trench cable laying device 14 to the cable bracket 10, and disconnect the wire rope and the end of the cable 12.

[0044] g. Repeat steps d to f until all cables 12 in the cable trench 9 are laid. Finally, remove the cable laying device 14, cable reel 11 and winding device 13 from the cable trench 9.

[0045] According to the number and type of cables 12 placed on each layer of cable support 10 in the design scheme, one or more cables 12 are pulled by the winding device 13 each time and placed on the corresponding cable support 10. Generally, multiple cables 12 on the same layer of cable support 10 are pulled at a time. Multiple cable reels 11 are placed at the entrance end of the cable trench 9, and multiple wire ropes are pulled simultaneously by the winding device 13. Since the cable trench cable laying device 14 of the present invention can greatly reduce the friction of the cables 12 during the pulling process, the pulling force of the winding device 13 is sufficient to pull multiple cables 12 at the same time, which can greatly improve the cable laying efficiency. Moreover, after the cables 12 of the same layer pass through the cable trench 9, they are adjusted to the corresponding height and aligned with the cable support 10, so that the cables 12 can be quickly moved to the cable support 10.

[0046] At least one cable trench laying device 14 is placed at the corner of the cable trench 9. The cable trench laying device 14 controls the position of the cable 12 at the corner and greatly reduces friction through the side conveying roller 6.

[0047] The concealed caster wheel 2 mechanism includes a pressing block disposed on the lower surface of the support plate 4, a concealed cylinder on the base 1, a connecting block passing through the concealed cylinder, and a caster wheel disposed at the bottom of the connecting block. When moving and adjusting the position of the cable trench laying device 14, the pressing block is inserted into the concealed cylinder to push the caster wheel at the bottom of the connecting block out of the lower surface of the base 1. After the position of the cable trench laying device 14 is determined, the support plate 4 is raised to a certain height, the caster wheel retracts into the concealed cylinder, and the base 1 contacts the ground.

[0048] The lifting mechanism 3 includes a first support rod and a second support rod arranged in a cross pattern. The rotating shaft passes through the middle of the first support rod and the middle of the second support rod. The upper end of the first support rod and the lower end of the second support rod are respectively hinged to the support plate 4 and the base 1. The lower end of the first support rod and the upper end of the second support rod are respectively hinged to the first slider and the second slider. The first slider is slidably mounted on the base 1, and the second slider is slidably mounted on the support plate 4. A lead screw is provided on the support plate 4. The lead screw passes through the second slider and is threadedly connected to the second slider. A handwheel is provided at the end of the lead screw.

[0049] The cable trench cable laying device 14 has the same structure and function as described above, and will not be repeated here.

[0050] The cable laying method of the present invention uses the above-mentioned cable laying device 14. The cable laying device 14 is arranged in the cable trench 9 at a certain interval. When the wire rope is wound by the winding device 13, the cable 12 moves in the conveying groove formed by the main conveying roller 5 and the side conveying roller 6. Since the main conveying roller 5 and the side conveying roller 6 can rotate, the friction with the cable 12 is reduced, so that the cable 12 can pass through the cable trench 9 smoothly. At the same time, at the corner, the side conveying roller 6 restricts the position of the cable 12, so that the cable 12 will not come out. Thus, the cable 12 will not come into contact with the ground, side wall, corner or cable support 10 in the cable trench 9 and generate friction, avoiding damage to the cable 12 and cable support 10 during the laying process and improving the laying efficiency.

[0051] This invention can improve the efficiency of cable laying in cable trench 9, reduce the number of construction personnel required for cable laying, and avoid damage to cable 12 and cable support 10 during the cable laying process.
