[0042] Embodiments of the present application will be described in more detail with reference to the drawings. While the present application is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the drawings are not intended to limit the application to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the application as defined by the appended claims.

[0043] With the continuous development of science and technology, the construction of cities is increasing, so some basic transmission lines in the city need to be laid in advance, such as water and electricity lines. In the process of laying transmission lines, cable laying is a core link. When laying cables, a cable trough is usually placed at a designated location first, and then a laying device is installed in the cable trough to support or guide the cable.

[0044] The cable laying installation device in the related art usually has 2 or 3 guide wheels fixedly arranged in the installation bracket, and the cable is supported and guided by passing through the guide wheels. However, since the guide wheels are usually fixed in the bracket, some large-sized cables cannot pass through the laying device.

[0045] A few laying devices capable of adjusting the guide wheels usually only open a sliding slot in the side plate of the bracket, and the position of the guide wheel is fixed by a bolt fastener. This fixing method requires the bolt to always maintain a preset pretightening force to achieve the fixing requirement of the guide wheel. However, as the cable moves, the bolt is easily loosened, causing the position of the guide wheel to deviate, which not only affects the service life of the guide wheel, but also causes the cable to lack clamping force on one side, damaging the guide track of the cable.

[0046] In addition, the cable laying installation device in the related art usually does not have a cable conveying function, and when the cable needs to be conveyed, a cable conveyor needs to be matched to realize the cable conveying, which increases the cost.

[0047] As Figures 1-3As shown, in order to at least solve the problem that the cable laying device cannot simultaneously meet the flexible and fixed stable adjustment of the guide wheel position, the embodiment of the application provides a laying and installation device for power transmission and transformation line cable, which comprises a main frame assembly 2, an expansion assembly 6, a positioning assembly 7 and a guide wheel assembly 8.

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

[0049] The expansion assembly 6 comprises two sliding frames 610 connected through a connecting part 620; each sliding frame 610 comprises a first part 611 and a second part 612; the second part 612 is movably arranged in the corresponding first groove 210, and the second part 612 is provided with a second groove 6121 in the first direction and a plurality of through holes 6122 in the second direction; the through holes 6122 are in communication with the second groove 6121.

[0050] The positioning assembly 7 comprises two transmission plates 710 and positioning blocks 720; the transmission plate 710 is movably arranged in the corresponding second groove 6121; the transmission plate 710 is vertically provided with a sliding rail 711 in a third direction. The sliding rail 711 is preferably a sliding groove penetrating the transmission plate 710. The positioning block 720 is provided with a through groove in the first direction, and the width of the through groove in the second direction is greater than the width of the transmission plate 710 in the second direction. The through groove is provided with a protrusion at the center position in the second direction, and the protrusion is fixedly connected with the opposite two side walls of the through groove in the third direction. The positioning block 720 is movably arranged on the sliding rail 711, preferably, the positioning block 720 is movably sleeved on the transmission plate 710 through the through groove, and the protrusion penetrates the sliding rail 711 and can slide on the sliding rail 711; each positioning block 720 is inserted into the corresponding through hole 6122 for following the movement of the positioning assembly 7, insertion or disengagement of the insertion hole; the third direction is perpendicular to the first direction and the second direction; the sliding rail 711 is inclined to the first direction and the second direction.

[0051] The guide wheel assembly 8 comprises a support guide wheel and a moving guide wheel 810; the two ends of the moving guide wheel 810 are rotatably arranged on the two first parts 611; the two ends of the support guide wheel are rotatably arranged on the main frame assembly 2; the central axis of the moving guide wheel 810 is parallel to the central axis of the support guide wheel.

[0052] Further, as shown in Figure 1 、 Figure 2 , the main frame assembly 2 is arranged at a specified position on the cable groove frame 1. The specified position is generally a position where the power transmission and transformation line cable needs to be supported and guided, and is preferably each corner.

[0053] The cable tray 1 generally has two vertical cable routing channels 110, and the inner walls of the cable routing channels 110 are provided with a plurality of support frames 120. The plurality of support frames 120 are preferably uniformly arranged at equal intervals in the horizontal direction to support the cables 130. The main frame assembly 2 is arranged on the inner walls of the cable routing channels 110.

[0054] As shown in Figure 3 , a three-dimensional rectangular coordinate system is established with the length direction of the main frame assembly 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. The two 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. Two first grooves 210 are arranged 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 vertical bisector of the bottom plate in the y-axis direction.

[0056] As shown in Figure 5 , Figure 6 , the two carriages 610 of the expansion assembly 6 are arranged along the first direction, and the connecting portion 620 of the expansion assembly is arranged along the third direction. The second portion 612 of the carriage 610 is movable in the first groove 210, and the first portion 611 of the carriage 610 cannot enter the first groove 210.

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

[0058] When the transmission plate 710 moves in the first direction, due to the inclination angle of the slide rail 711 in the first direction and the second direction, the positioning block 720 moves in the first direction relative to the transmission plate 710, and also generates displacement in the second direction, thereby extending out of the through hole 6122 to be inserted into the insertion hole of the first groove 210, so as to fix the expansion assembly 6 and the main frame assembly 2.

[0059] The central axes of the support guide wheels and the moving guide wheels 810 are parallel to the x-axis. The moving guide wheels 810 are arranged on the first portions 611 of the two expansion assemblies 6, and the support guide wheels are arranged on the main frame assembly 2, so that when the expansion assembly 6 moves, the distance between the moving guide wheels 810 and the support guide wheels can be adjusted, thereby adapting to the laying requirements of power transmission and transformation cables of different sizes.

[0060] The process of laying the power transmission line cable by using the laying installation device of the embodiment of the application is as follows: after the laying installation device is installed at a designated position, the positioning assembly 7 is moved in the first direction until the positioning block 720 is disengaged from the insertion hole; after the extension assembly 6 is moved by a first distance away from the side of the main frame assembly 2, the positioning assembly 7 is moved in the opposite direction of the first direction so that the positioning block 720 is inserted into the insertion hole; the power transmission line cable is passed between the moving guide wheel 810 and the supporting guide wheel to lay the cable until the laying of the power transmission line cable is completed; the positioning assembly 7 is moved again in the first direction until the positioning block 720 is disengaged from the insertion hole; after the extension assembly 6 is moved towards the side of the main frame assembly 2 until the moving guide wheel 810 is in contact with the power transmission line cable, the positioning assembly 7 is released so that the positioning block 720 is inserted into the insertion hole, and the position of the extension assembly 6 is fixed.

[0061] The laying installation device of the power transmission line cable provided by the embodiment of the application can flexibly adjust the distance between the moving guide wheel 810 and the supporting guide wheel by arranging the extension assembly 6 that can move on the main frame assembly 2 and arranging the moving guide wheel 810 on the extension assembly 6 and the supporting guide wheel on the main frame assembly 2, thereby meeting the laying requirements of power transmission line cables of different sizes.

[0062] Further, the movable transmission plate 710 is arranged on the second groove 6121 of the extension assembly 6, and the slide rail 711 is arranged on the transmission plate 710, so that the positioning block 720 can pass through the transmission plate 710 and be inserted into or disengaged from the insertion hole on the main frame assembly 2 while moving on the slide rail 711. When the positioning block 720 is inserted into the insertion hole, the extension assembly 6 and the main frame assembly 2 are fixed, and the position of the moving guide wheel 810 is further fixed.

[0063] Since the insertion hole is arranged in the second direction and the extension assembly 6 moves in the first direction perpendicular to the second direction, when the positioning block 720 is inserted into the insertion hole, the positioning block will not be damaged due to the shear force in the first direction applied to the moving guide wheel 810 and the extension assembly 6 during the laying of the power transmission line cable. Only by applying pressure to the positioning block 720 in the second direction through the movement of the transmission plate 710 can the positioning block 720 be driven to move, so that the moving guide wheel 810 and the extension assembly 6 are fixed stably and reliably, thereby solving the problem that the cable laying device cannot simultaneously meet the requirements of flexible adjustment and stable fixation of the position of the guide wheel.

[0064] Further preferably, the through holes 6122 are uniformly arranged on the second part 612 at a set distance. The opposite two inner walls of the first groove 210 are symmetrically provided with a plurality of insertion holes; the insertion holes on each inner wall are uniformly arranged at a set distance, so that the distance between adjacent insertion holes is equal to the distance between adjacent through holes 6122.

[0065] Further preferably, the size of the insertion hole is the same as that of the through hole 6122.

[0066] As shown in Figure 5 Fig. 6, since the through hole 6122 is through the second part 612, and the second part 612 is provided with the second slot 6121, in the second direction, the second part 612 forms a through hole in the inner wall on both sides of the second slot 6121. The number of the positioning blocks 720 of the positioning assembly 7 is the same as that of the through holes 6122. The two ends of each positioning block 720 are inserted into the corresponding through holes on both sides of the second slot 6121.

[0067] Further preferably, in the second direction, the second slot 6121 is arranged 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, so as to ensure that the expansion assembly 6 can slide in the first slot 210, and facilitate the positioning block 720 to extend out of the through hole 6122 to be inserted into the insertion hole.

[0068] Further preferably, the slide rail 711 comprises a plurality of first segments 7111 and a plurality of second segments 7112, and the plurality of first segments 7111 and the plurality of second segments 7112 are arranged alternately. The first segment 7111 and the second segment 7112 are the same in size; the first segment 7111 is arranged at a first included angle with the second direction; the second segment 7112 is arranged at a second included angle with the second direction; the first included angle and the second included angle are in a complementary relationship; each positioning block 720 is movably arranged on a first segment 7111 or a second segment 7112; and the set interval is equal to the length of the projection of the first segment 7111 in the second direction.

[0069] Further preferably, the first segment 7111 and the second segment 7112 are defined as slide segments, and the convex block at the center of each positioning block 720 is movably inserted into the corresponding slide segment.

[0070] When each positioning block 720 moves to the center position of the slide segment, the two ends of the positioning block 720 are flush with the outer surface of the second part 612 in the second direction.

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

[0072] When each positioning block 720 moves to the top and bottom positions of the slide segment, the part of one end of the positioning block 720 extending into the insertion hole reaches the maximum, and preferably the inside of the insertion hole is filled with the positioning block 720.

[0073] The embodiment of the present application adjusts the moving position of the positioning block 720 in the second direction by moving the transmission plate 710 in the second groove 6121, so as to realize the fixing or releasing of the expansion assembly 6 and the main frame assembly 2.

[0074] Further preferably, the positioning assembly 7 further comprises two connecting frames 730 and a connecting block 740; one end of each connecting frame 730 is connected with the transmission plate 710, and the other end is connected with one end of the connecting block 740. The connecting block 740 is provided with two through grooves 741 at two ends in the first direction; each first part 611 is connected with the connecting part 620 by penetrating through the corresponding through groove 741. The two connecting frames 730 are arranged on the opposite sides of the first part 611 respectively; the end of the connecting frame 730 connected with the transmission plate 710 is provided with a through hole for the second part 612 to penetrate.

[0075] The embodiment of the present application connects the two transmission plates 710 by arranging the connecting frame 730 and the connecting block 740, so as to realize the synchronous movement of the two transmission plates 710, thereby facilitating the movement and fixing of the expansion assembly 6. By arranging the through groove 741 and the through hole in the connecting frame 730, the expansion assembly can be avoided, so as to avoid affecting the movement of the expansion assembly 6.

[0076] Further, the connecting part 620 is arranged at the end of the first part 611 away from the second part 612; the connecting block 740 is provided with a fifth groove at the side away from the connecting frame 730; the shape of the fifth groove is matched with the shape of the connecting part 620. When the laying and installation equipment is not used, the positioning assembly 7 can be moved to the initial position, so that the connecting part 620 is placed in the fifth groove, thereby facilitating the taking and placing of the laying and installation equipment.

[0077] Further, as shown in the figure, Figure 4 The support guide wheel comprises a first guide wheel 820 and a second guide wheel 830.
