[0042] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0043] With the continuous development of technology, urban construction is increasing, necessitating the early laying of basic transmission and transformation lines within cities, such as waterways and electrical circuits. Cable laying is a crucial step in this process. When laying cables, cable trays are typically placed at designated locations first, and then laying equipment is installed within the trays to support or guide the cables.

[0044] Cable laying and installation equipment in related technologies typically has two or three guide rollers fixedly installed in the mounting bracket. The cable is supported and guided by passing it through the guide rollers. However, because the guide rollers are usually fixed in the bracket, some larger cables cannot pass through the laying equipment.

[0045] A few cable laying devices capable of adjusting guide rollers typically only have grooves cut into the side plates of the support frame, and the guide rollers are fixed in position using bolts. This fixing method requires the bolts to maintain a preset preload to achieve the desired fixation. However, as the cable moves, the bolts can easily loosen, causing the guide rollers to shift position. This not only affects the lifespan of the guide rollers but also results in insufficient clamping force on one side of the cable, disrupting the cable's guiding trajectory.

[0046] In addition, cable laying and installation equipment in related technologies usually does not have cable conveying function. When it is necessary to convey cables, a cable conveyor is required to achieve cable conveying, which leads to an increase in cost.

[0047] like Figures 1-3As shown, in order to at least solve the problem that cable laying equipment cannot simultaneously meet the requirements of flexible adjustment of guide wheel position and stable fixation, the embodiments of the present invention provide a cable laying and installation equipment for power transmission and transformation lines, including: main frame assembly 2, extension assembly 6, positioning assembly 7 and guide wheel assembly 8.

[0048] The main frame assembly 2 is provided with two first slots 210 in the first direction, and the inner wall of each first slot 210 is provided with an insertion hole in the second direction; the first direction is perpendicular to the second direction.

[0049] The expansion component 6 includes two carriages 610 connected to each other via a connecting part 620. Each carriage 610 includes a first part 611 and a second part 612. The second part 612 is movably disposed in a corresponding first groove 210. The second part 612 has a second groove 6121 in a first direction and a plurality of through holes 6122 in a second direction. The through holes 6122 communicate with the second groove 6121.

[0050] The positioning component 7 includes two transmission plates 710 and a positioning block 720. The transmission plates 710 are movably disposed within corresponding second grooves 6121. A slide rail 711 is vertically disposed on the transmission plate 710 in a third direction. The slide rail 711 is preferably a sliding groove penetrating the transmission plate 710. The positioning block 720 has a through groove in a first direction, and the width of the through groove in a second direction is greater than the width of the transmission plate 710 in the second direction. A protrusion is disposed at the center of the through groove in the second direction, and the protrusion is fixedly connected to the opposite side walls of the through groove on both sides in the third direction. The positioning block 720 is movably disposed on the slide rail 711. Preferably, the positioning block 720 is movably sleeved on the transmission plate 710 through a through groove, so that the protrusion passes through the slide rail 711 and can slide on the slide rail 711. Each positioning block 720 is inserted into the corresponding through hole 6122 to follow the movement of the positioning component 7 and to be inserted into or removed from the hole. The third direction is perpendicular to the first direction and the second direction. The slide rail 711 is inclined to the first direction and the second direction.

[0051] The guide wheel assembly 8 includes a supporting guide wheel and a movable guide wheel 810; the two ends of the movable guide wheel 810 are rotatably mounted on two first parts 611; the two ends of the supporting guide wheel are rotatably mounted on the main frame assembly 2; the central axis of the movable guide wheel 810 is parallel to the central axis of the supporting guide wheel.

[0052] Furthermore, such as Figure 1 , Figure 2 As shown, the main frame assembly 2 is positioned at a designated location on the cable tray 1. These designated locations are typically where the power transmission line cables need to be supported and guided, preferably at various corners.

[0053] The cable tray 1 typically has two vertical cable trays 110, and the inner wall of each cable tray 110 is provided with multiple support frames 120. The multiple support frames 120 are preferably evenly spaced horizontally to support the cables 130. The main frame assembly 2 is disposed on the inner wall of the cable tray 110.

[0054] like Figure 3 As shown, a three-dimensional Cartesian coordinate system is established with the length direction of the main frame component 2 as the y-axis, the width direction as the x-axis, and the height direction as the z-axis. The first direction is parallel to the z-axis, the second direction is parallel to the y-axis, and the third direction is parallel to the x-axis.

[0055] The main frame assembly 2 includes two side plates and a bottom plate. Both side plates are arranged parallel to the z-axis direction, and the two ends of the bottom plate are connected to the two side plates respectively. Two first grooves 210 are respectively provided on the two side plates and penetrate the upper and lower surfaces of the side plates. The two first grooves 210 are symmetrically arranged along the perpendicular bisector of the bottom plate in the y-axis direction.

[0056] Combination Figure 5 , Figure 6 As shown, the two carriages 610 of the extension component 6 are arranged along a first direction, and the connecting part 620 of the extension component is arranged along a third direction. The second part 612 of the carriage 610 can move within the first groove 210, while the first part 611 of the carriage 610 cannot enter the first groove 210.

[0057] The two transmission plates 710 of the positioning assembly 7 can move within the second grooves 6121 on the second part 612 of the two carriages 610, respectively. The transmission plate 710 is provided with a slide rail 711 in the third direction, and a plurality of positioning blocks 720 are provided with through grooves in the first direction. Each positioning block 720 is sleeved on the transmission plate 710 and slidably connected to the slide rail 711, and both ends of the positioning block 720 are respectively inserted into the through holes 6122 of the second part 612.

[0058] When the transmission plate 710 moves in the first direction, since the slide rail 711 has a certain tilt angle with both the first and second directions, the positioning block 720 will also be displaced in the second direction while moving relative to the transmission plate 710 in the first direction, thereby extending out of the through hole 6122 and being inserted into the insertion hole of the first slot 210 to achieve the fixation between the expansion component 6 and the main frame component 2.

[0059] The central axes of both the support guide wheel and the movable guide wheel 810 are parallel to the x-axis. The movable guide wheel 810 is mounted on the first part 611 of the two extension components 6, while the support guide wheel is mounted on the main frame component 2. This allows the distance between the movable guide wheel 810 and the support guide wheel to be adjusted when the extension components 6 move, thereby adapting to the laying requirements of power transmission and transformation line cables of different sizes.

[0060] The process of laying power transmission line cables using the laying and installation equipment of this invention is as follows: After installing the laying and installation equipment at the designated position, the positioning component 7 is moved along the first direction until the positioning block 720 disengages from the socket; the extension component 6 is moved a first distance away from the main frame component 2, and then the positioning component 7 is moved in the opposite direction of the first direction so that the positioning block 720 is inserted into the socket; the power transmission line cable is passed between the moving guide wheel 810 and the support guide wheel to lay the cable until the power transmission line cable is laid; the positioning component 7 is moved again along the first direction until the positioning block 720 disengages from the socket; the extension component 6 is moved closer to the main frame component 2 until the moving guide wheel 810 contacts the power transmission line cable, and then the positioning component 7 is released so that the positioning block 720 is inserted into the socket, thus fixing the position of the extension component 6.

[0061] The present invention provides a cable laying and installation device for power transmission and transformation lines. By setting an extension component 6 that can move on the main frame assembly 2, and setting a movable guide wheel 810 on the extension component 6 and a support guide wheel on the main frame assembly 2, the distance between the movable guide wheel 810 and the support guide wheel can be flexibly adjusted to meet the laying requirements of power transmission and transformation line cables of different sizes.

[0062] Furthermore, by providing a movable transmission plate 710 on the second slot 6121 of the extension component 6, and by providing a slide rail 711 on the transmission plate 710, the positioning block 720 can pass through the transmission plate 710 and insert into or disengage from the insertion hole on the main frame component 2 while moving on the slide rail 711. When the positioning block 720 is inserted into the insertion hole, the extension component 6 and the main frame component 2 can be fixed, thereby fixing the position of the moving guide wheel 810.

[0063] Since the socket is located in the second direction, and the expansion component 6 moves in the first direction perpendicular to the second direction, the positioning block 720 will not be damaged by the shearing force applied to the moving guide wheel 810 and the expansion component 6 in the first direction when it is inserted into the socket. Only by applying pressure to the positioning block 720 in the second direction through the moving transmission plate 710 can the positioning block 720 be driven to move. This makes the moving guide wheel 810 and the expansion component 6 fixed stably and reliably, which can solve the problem that cable laying equipment cannot simultaneously meet the requirements of flexible adjustment of guide wheel position and stable fixation.

[0064] More preferably, the through holes 6122 are evenly arranged in the second part 612 at a set interval. Multiple insertion holes are symmetrically arranged on the two opposite inner walls of the first groove 210; the insertion holes on each inner wall are evenly arranged at a set interval, so that the distance between adjacent insertion holes is equal to the distance between adjacent through holes 6122.

[0065] More preferably, the size of the jack is the same as the size of the through hole 6122.

[0066] like Figure 5 As shown, since the through hole 6122 penetrates the second part 612, and the second part 612 is provided with a second groove 6121, in the second direction, the second part 612 forms through holes on both sides of the inner wall of the second groove 6121. The number of positioning blocks 720 of the positioning assembly 7 is the same as the number of through holes 6122. Both ends of each positioning block 720 are inserted into the corresponding through holes located on both sides of the second groove 6121.

[0067] Furthermore, preferably, in the second direction, the second groove 6121 is located at the center of the second part. The length of the positioning block 720 in the second direction is equal to the length of the second part 612 in the second direction, thereby ensuring that the extension component 6 can slide within the first groove 210, and also facilitating the positioning block 720 to extend from the through hole 6122 to be inserted into the socket.

[0068] Furthermore, the slide rail 711 includes multiple first segments 7111 and multiple second segments 7112; the multiple first segments 7111 and multiple second segments 7112 are alternately arranged. The first segments 7111 and the second segments 7112 have the same size; the first segment 7111 is provided with a first angle to the second direction; the second segment 7112 is provided with a second angle to the second direction; the first angle and the second angle are complementary; each positioning block 720 is movably disposed on one of the first segments 7111 or the second segment 7112; the set spacing is equal to the length of the projection of the first segment 7111 in the second direction.

[0069] Furthermore, both the first segment 7111 and the second segment 7112 are defined as sliding segments, and the protrusion at the center of each positioning block 720 can be movably inserted into the corresponding sliding segment.

[0070] When each positioning block 720 moves to the center position of the slide, both ends of the positioning block 720 are flush with the outer surfaces of the second part 612 on both sides in the second direction.

[0071] When each positioning block 720 moves to a position other than the center position of the slide, one end of each positioning block 720 extends to the outside of the second part 612 to be inserted into the corresponding socket.

[0072] When each positioning block 720 moves to the top and bottom positions of the slide, the portion of one end of the positioning block 720 extending into the socket reaches its maximum, preferably the entire interior of the socket is filled with positioning blocks 720.

[0073] In this embodiment of the invention, by moving the transmission plate 710 within the second groove 6121, the position of the positioning block 720 in the second direction can be adjusted, thereby fixing or releasing the extension component 6 from the main frame component 2.

[0074] More preferably, the positioning component 7 further includes: two connecting frames 730 and a connecting block 740; one end of each connecting frame 730 is connected to the transmission plate 710, and the other end is connected to one end of the connecting block 740. Two through slots 741 are provided at both ends of the connecting block 740 in a first direction; each first part 611 passes through the corresponding through slot 741 and connects to the connecting part 620. The two connecting frames 730 are respectively disposed on opposite sides of the first part 611; the end of the connecting frame 730 connected to the transmission plate 710 is provided with a through hole for the second part 612 to pass through.

[0075] In this embodiment of the invention, by setting a connecting frame 730 and a connecting block 740 to connect two transmission plates 710, the synchronous movement of the two transmission plates 710 can be achieved, thereby facilitating the movement and fixation of the expansion component 6. By setting a through slot 741 and a through hole in the connecting frame 730, the expansion component can be avoided, thus preventing interference with the movement of the expansion component 6.

[0076] Furthermore, the connecting part 620 is located at the end of the first part 611 away from the second part 612; the connecting block 740 has a fifth groove on the side away from the connecting frame 730; the shape of the fifth groove matches the shape of the connecting part 620. When the laying and installation equipment is not in use, the positioning component 7 can be moved to the initial position so that the connecting part 620 is placed in the fifth groove, making it convenient to pick up and put down the laying and installation equipment.

[0077] Furthermore, such as Figure 4 As shown, the supporting guide wheel includes a first guide wheel 820 and a second guide wheel 830. The connecting plane of the central axis of the first guide wheel 820 and the central axis of the second guide wheel 830 is parallel to the second direction; the central axis of the movable guide wheel 810 is located on the perpendicular bisector of the connecting plane.

[0078] Furthermore, the laying and installation equipment is preferably equipped with a conveying assembly 3. The conveying assembly includes a conveyor belt 310. The conveyor belt 310 is wound around the first guide wheel 820 and the second guide wheel 830.

[0079] In this embodiment of the invention, by setting a first guide wheel 820 and a second guide wheel 830, the center lines of the supporting guide wheel and the moving guide wheel 810 form an isosceles triangle, thereby providing better support stability and a better clamping effect on the cable. By setting a conveyor belt 310 on the supporting guide wheel, the cable 130 can be transported auxiliaryly.

[0080] More preferably, the surface of the conveyor belt 310 is provided with multiple grooves at equal intervals in the third direction, which can increase the friction between the surface of the conveyor belt 310 and the cable 130, thereby making the conveying of the cable 130 more stable.

[0081] like Figure 8 As shown, the conveying assembly 3 of the laying and installation equipment also includes a tension adjustment assembly; the tension adjustment assembly includes a tension block 320, a tension roller 330, and an adjustment rod 340.

[0082] Tension block 320 is movably disposed on main frame assembly 2 in a first direction; tension block 320 is disposed on the side of conveyor belt 310 away from moving guide wheel 810; main frame assembly 2 is provided with third groove 230 for tension block 320 to slide in the first direction.

[0083] Tension roller 330 is disposed on the side of tension block 320 close to conveyor belt 310, and is used to squeeze conveyor belt 310 to adjust the tension of conveyor belt 310.

[0084] The adjusting rod 340 is rotatably connected at one end to the tension block 320 and passes through the main frame assembly 2 at the other end; the central axis of the adjusting rod 340 is parallel to the first direction; the adjusting rod 340 is threadedly connected to the main frame assembly 2.

[0085] In an embodiment of the present invention, when the tension of the conveyor belt 310 is insufficient, the adjusting rod 340 can be rotated to squeeze the tension roller 330, causing the tension roller 330 to move closer to the conveyor belt 310 under the action of the adjusting rod 340, thereby tightening the conveyor belt 310 to increase the tension of the conveyor belt 310.

[0086] Furthermore, such as Figure 7 As shown, the main frame assembly 2 is provided with multiple fixing slots 220; the fixing slots 220 are equipped with drive components; the drive components are connected to the first guide wheel 820 and / or the second guide wheel 830 for transmission.

[0087] Furthermore, the drive components include: motor drive mechanism, hydraulic drive mechanism, pneumatic drive mechanism, etc.

[0088] Furthermore, the outer end of the guide rod supporting the guide wheel is also provided with an external connector, which is located outside the main frame assembly 2 to connect with the output end of the drive assembly, so as to facilitate transmission with the drive assembly.

[0089] In this embodiment of the invention, a drive assembly can be directly installed in the fixing slot 220 of the main frame assembly 2. The drive assembly drives the first guide wheel 820 and / or the second guide wheel 830 to rotate, thereby driving the conveyor belt 310 to operate. When it is necessary to move the cable 130 during the laying of power transmission and transformation line cables, this embodiment of the invention can directly drive the cable 130 to move using the laying and installation equipment, without the need for an additional cable conveyor, thus saving costs while optimizing resource allocation and space utilization.

[0090] Furthermore, such as Figure 5 , Figure 6 , Figure 9 As shown, the first part 611 is provided with a fourth groove 6111 in the first direction; a slider 630 is movably provided in the fourth groove 6111; a movable guide wheel 810 is rotatably provided on the slider 630; one side of the slider 630 is connected to the inner wall of the fourth groove 6111 by a first spring 640.

[0091] The present invention provides a fourth groove 6111, a slider 630 and a first spring 640 on the first part 611, and rotatably connects the movable guide wheel 810 to the slider 630. Under the pressure of the first spring 640, the movable guide wheel 810 is squeezed toward the cable 130, thereby further improving the clamping force on the cable 130 and making the conveying and guiding of the cable 130 more stable.

[0092] Furthermore, combining Figure 3 , Figure 4 As shown, the installation equipment also preferably includes two auxiliary components 4 disposed on opposite sides of the main frame assembly 2 in the second direction; each auxiliary component 4 includes a fixing plate 410, two extension blocks 440 and an elastic partition 430.

[0093] The fixed plate 410 is fixedly connected to the side plate of the main frame assembly 2 via two rotating shafts 420; the central axis of each rotating shaft 420 is parallel to the second direction. Two expansion blocks 440 are rotatably mounted on their respective rotating shafts 420; each expansion block 440 is provided with a support assembly 5. An elastic partition 430 is disposed between the two expansion blocks 440; a second spring 431 is provided between the first and second ends of the elastic partition 430; the first and second ends are respectively connected to the two expansion blocks 440.

[0094] The present invention provides an embodiment in which two sets of auxiliary components are provided on both sides of the main frame assembly 2, and two extension blocks of the auxiliary components are rotated around a pivot. The two extension blocks 440 are connected by an elastic spacer 430, which facilitates the adjustment of the angle of the extension blocks 440 and the support components 5 installed on the extension blocks 440, and provides good support for the support components 5. Thus, the support spacing and angle of the four support components 5 can be adjusted to meet different wall fixing requirements for different usage scenarios.

[0095] Furthermore, the elastic partition 430 includes an elastic sheet, both ends of which are bent inwards, forming a V-shape. The two ends of the second spring 431 are fixedly connected to the two ends of the elastic sheet. The two ends of the elastic sheet are connected to two extension blocks 440 respectively.

[0096] The embodiments of the present invention utilize the dual elastic force of the elastic sheet and the second spring 431 to provide better elastic support for the expansion block and facilitate adjustment of the angles of the expansion block 440 and the support component 5.

[0097] like Figure 7 As shown, a connecting rod 460 is also provided between the fixed plate 410 and the main frame assembly 2. The connecting rod 460 is inserted into the elastic sheet of the elastic partition 430 and is located at the bending center of the elastic sheet, which facilitates the rotation of the elastic partition 430, thereby making the adjustment of the support assembly 5 more flexible and improving its spatial freedom.

[0098] The auxiliary component 4 preferably includes a baffle 450. A baffle 450 is provided at both ends of each fixed plate 410 and between it and the main frame assembly 2. The baffle 450 is fixedly connected to both the fixed plate 410 and the main frame assembly 2. By setting the baffle 450, the expansion block 440 is restricted within the space enclosed by the fixed plate 410, the main frame assembly 2 and the baffle 450.

[0099] Furthermore, such as Figure 3 , Figure 10 As shown, the support assembly 5 preferably includes: four telescopic rods 510, a stabilizing plate 520, and a reinforcing head 530.

[0100] Four telescopic rods 510, each with an outer sleeve that passes through the corresponding extension block 440 and is fixedly connected to the extension block 440; each telescopic rod 510 has a ball head 511 at the end away from the moving guide wheel 810 in the first direction.

[0101] The stabilizing plate 520 is rotatably connected to the ball head 511 on one side and has a plug hole on the other side.

[0102] The reinforcing head 530 is detachably mounted on the insertion hole; a cone is provided on the side of the reinforcing head 530 away from the stabilizing plate 520.

[0103] Furthermore, the telescopic rod 510 includes a slidingly connected outer rod and an inner movable rod. In this embodiment of the invention, by fixing the outer rod of the telescopic rod 510 to the extension block 440 and adjusting the length of the telescopic rod 510 by moving the inner movable rod, the distance between the main frame assembly 2 and the wall can be adjusted, thereby adjusting the distance between the cable 130 and the wall, thus meeting different cable laying requirements.

[0104] In this embodiment of the invention, the telescopic rod 510 and the stabilizing plate 520 are connected by a ball joint, allowing the angle of the stabilizing plate 520 to be adjusted arbitrarily to contact the wall surface at different angles, thereby providing support for the entire laying and installation equipment. If the wall surface has a complex shape and poor smoothness, a reinforcing head 530 can be added to the stabilizing plate 520. The conical head of the reinforcing head 530 increases the pressure on the wall surface, making the support component 5 more stable.

[0105] like Figure 11 As shown, one embodiment of the present invention also provides a method for laying power transmission and transformation line cables, including the following steps.

[0106] Step S1: After installing the laying and installation equipment in the designated position, move the positioning component 7 along the first direction until the positioning block 720 disengages from the socket.

[0107] In step S2, after moving the expansion component 6 a first distance away from the main frame component 2, the positioning component 7 is moved in the opposite direction of the first direction so that the positioning block 720 is inserted into the socket.

[0108] Step S3: Pass the power transmission line cable through the moving guide wheel 810 and the supporting guide wheel to lay the cable until the power transmission line cable laying is completed.

[0109] Step S4: Move the positioning component 7 again along the first direction until the positioning block 720 disengages from the socket.

[0110] Step S5: Move the expansion component 6 to the side closer to the main frame component 2 until the moving guide wheel 810 contacts the power transmission and transformation line cable, then release the positioning component 7 so that the positioning block 720 is inserted into the socket to fix the position of the expansion component 6.

[0111] The present invention provides a method for laying power transmission and transformation line cables. By setting an extension component 6 that can move on the main frame assembly 2, and setting a movable guide wheel 810 on the extension component 6 and a support guide wheel on the main frame assembly 2, the distance between the movable guide wheel 810 and the support guide wheel can be flexibly adjusted to meet the laying requirements of power transmission and transformation line cables of different sizes.

[0112] Furthermore, by providing a movable transmission plate 710 on the second slot 6121 of the extension component 6, and by providing a slide rail 711 on the transmission plate 710, the positioning block 720 can move along the slide rail 711 while passing through the transmission plate 710 and inserting or disengaging from the socket on the main frame component 2. When the positioning block 720 is inserted into the socket, the extension component 6 and the main frame component 2 can be fixed, thereby fixing the position of the moving guide wheel 810. This ensures that the moving guide wheel 810 and the extension component 6 are fixed stably and reliably, solving the problem that cable laying equipment cannot simultaneously meet the requirements of flexible guide wheel position adjustment and stable fixation.

[0113] Furthermore, the method of the present invention preferably includes the following steps:

[0114] Step S6: Detect the tension of the conveyor belt 310. When the tension of the conveyor belt 310 is insufficient, rotate the adjusting rod 340 to press the tension roller 330. The conveyor belt 310 is wound around a support guide wheel, which includes a first guide wheel 820 and a second guide wheel 830. One end of the adjusting rod 340 is rotatably connected to the tension block 320, and the other end passes through the main frame assembly 2. The adjusting rod 340 is threadedly connected to the main frame assembly 2. The tension block 320 is movably mounted on the main frame assembly 2 in a first direction. The tension roller 330 is located on the side of the tension block 320 close to the conveyor belt 310.

[0115] In step S7, the tension roller 330 moves towards the side closer to the conveyor belt 310 under the action of the adjusting rod 340, pressing the conveyor belt 310 to increase the tension of the conveyor belt 310.

[0116] The present invention provides an embodiment in which a conveyor belt 310 is installed on a support guide wheel, which can assist in the conveying of the cable 130. When the tension of the conveyor belt 310 is insufficient, the adjusting rod 340 can be rotated to increase the tension of the conveyor belt 310, thereby ensuring the conveying effect and conveying stability of the conveyor belt 310.
