Description

Technical Field

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

[0002] Power engineering, that is, engineering related to the production, transmission and distribution of electric energy, uses cable laying bridges when laying cables. They can be erected independently or laid on various buildings (structures) and pipe gallery supports. When the existing cable laying bridges are in use, the cables are all stored inside the bridges, and most of the bridges are not equipped with limiting structures. The cables in the bridges are scattered, affecting the later maintenance.

[0003] In order to solve the problems existing in the prior art, people have conducted long-term exploration and proposed various solutions. For example, the Chinese patent literature discloses a patent with the publication number of CN216436719U, which discloses a cable laying bridge for power engineering, which includes a bridge and a top plate. The surface of the inner wall of the bridge is fixedly connected with a plurality of telescopic components, one end of the telescopic component is fixedly connected with a support plate, and the top and bottom of the inner wall of the support plate are fixedly connected with a damping bearing, and a rotating shaft is passed through the damping bearing. The beneficial effect is that the cable laying bridge for power engineering, through the rotation of the rotating shaft in the damping bearing, pulls the cable during the wiring process, and the cable surface fits the auxiliary wheel, and the auxiliary wheel rotates with the help of the auxiliary wheel, which can achieve the purpose of improving the wiring efficiency.

[0004] The above scheme separates the cables by opening cable troughs, which solves the existing technical problems to a certain extent. However, there are still the following shortcomings: the size of the cable trough depends on the diameter of the cable. When in use, it is necessary to match the appropriate bridge according to the size of the cable to achieve limited laying of the cable. There are certain limitations in use. It is difficult to apply to cables of different diameters and the flexibility is not high enough. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings, the technical problem is: to provide a cable laying bridge for power engineering.

[0006] The technical solution is: a cable laying bridge for power engineering, including a frame, a limit frame and a slider. There are five limit frames, which are distributed in a straight line. Sliders are slidably connected on both sides of the limit frames, and frames are connected between the front side of the slider and the rear side of the slider on the rear side. The bridge also includes limit blocks, partition plates, limit columns, adjustment components and transmission components. The limit blocks are symmetrically connected on the inner walls of the two frames. The limit blocks are located above the limit frames on the same side.

A plurality of partition plates are evenly spaced on the limit columns, wherein the middle partition plate is fixedly connected to the limit column, and the remaining partition plates are slidably connected to the limit columns. The partition plates are located above the corresponding limit frames and aligned with the corresponding limit blocks. An adjustment component is provided in the limit column, and a transmission component is provided on the frame.

[0007] Furthermore, the cable is laid on the limit frame through separation and limitation of the separation plate and the limit block.

[0008] Furthermore, two installation grooves for assisting the installation of the bridge are provided on the lower sides of the three limiting frames in the middle.

[0009] Furthermore, the adjustment component includes a spiral shaft and a pushing component. The spiral shaft is rotatably connected in the limiting column. Arc grooves are evenly spaced on both sides of the spiral shaft. A limiting groove is opened in the middle of the spiral shaft. A partition plate fixedly connected to the limiting column is rotatably connected to the corresponding limiting groove. The arc grooves on the front and rear sides are distributed in a mirror image, and the arc surface angle of the arc groove gradually increases from the inside to the outside. The slidable partition plates are slidably connected to the corresponding arc grooves respectively, and a pushing component is provided on the frame.

[0010] Furthermore, the pushing assembly includes a rotating rod, a rack rack and a gear. The two bottom sides of the two frames are rotatably connected to the rotating rods, the leftmost limit frame and the rightmost limit frame are slidably connected to the rack rack, the inner side of the rotating rod is rotatably connected to the rack rack on the same side, and two gears are connected to the middle of the spiral shaft, and the rack rack is meshed with the two gears on the same side.

[0011] Furthermore, the transmission assembly includes a support block, a worm, a knob, a bidirectional lead screw and a worm wheel. A support block is symmetrically connected to the front side wall of the front frame, a worm is rotatably connected between the two support blocks, both ends of the worm are connected to a knob, the second limit frame and the fourth limit frame from left to right are rotatably connected to the bidirectional lead screw, the bidirectional lead screw is threadedly connected to the two sliders on the same side, the front side of the bidirectional lead screw is connected to a worm wheel, and the worm wheel is meshed with the worm.

[0012] Furthermore, the bridge frame also includes a support frame, an articulated frame 1, an articulated frame 2, a buffer spring, a torsion spring and a telescopic roller. Support frames are connected to both ends of the two frames, and the two symmetrical support frames are slidably telescopically connected. The support frames are rotatably connected to the articulated frame 1, and the articulated frame 1 is rotatably connected to the articulated frame 2. Buffer springs are connected between the articulated frame 1 and the support frame on the same side, and torsion springs are connected between the articulated frame 2 and the articulated frame 1 on the same side.

DETAILED DESCRIPTION

[0035] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Embodiment: A cable laying bridge for power engineering, such as Figure 1-Figure 15 As shown, it includes a frame 1, a limit frame 101, a slider 103, a limit block 201, a partition plate 202, a limit column 203, an adjustment component and a transmission component. There are five limit frames 101, and the limit frames 101 are distributed in a straight line. The front and rear sides of the limit frames 101 are slidably connected with sliders 103. The front side of the slider 103 on the front side and the rear side of the slider 103 on the rear side are connected to the frame 1 by bolts. The lower sides of the three limit frames 101 in the middle are provided with two installation grooves 104 for auxiliary installation of the bridge. The limit blocks 201 are symmetrically connected to the inner walls of the two frames 1, and the limit blocks 201 are located on the limit frames 101 on the same side. In the leftmost and rightmost limit frames 101, limit columns 203 are fixedly connected, the limit columns 203 are slidably connected to the slider 103 on the same side, nine partition plates 202 are evenly spaced on the limit columns 203, the middle partition plate 202 is fixedly connected to the limit column 203, and the remaining partition plates 202 are slidably connected to the limit columns 203, the partition plates 202 are located above the corresponding limit frames 101 and aligned with the corresponding limit blocks 201, the cables 102 are laid on the limit frames 101 through the separation and limitation of the partition plates 202 and the limit blocks 201, an adjustment component is provided in the limit columns 203, and a transmission component is provided on the frame 1.

[0037] like Figure 7-Figure 12 As shown, the adjustment component includes a screw shaft 204 and a pushing component. The screw shaft 204 is rotatably connected in the limiting column 203. The front and rear sides of the screw shaft 204 are evenly spaced with arc grooves 205. The middle of the screw shaft 204 is provided with a limiting groove 206. A partition plate 202 fixedly connected to the limiting column 203 is rotatably connected to the corresponding limiting groove 206. The arc grooves 205 on the front and rear sides are distributed in a mirror image, and the arc angle of the arc groove 205 gradually expands from the inside to the outside. The large, slidable partition plates 202 are slidably connected to the corresponding arc grooves 205 respectively, and the spiral shaft 204 drives the arc grooves 205 to rotate. The arc grooves 205 can make the front and rear partition plates 202 gradually move outward. Due to the different angles of the arc grooves 205, the moving distances between the partition plates 202 are different. The larger the angle of the arc grooves 205, the larger the moving distance of the partition plates 202. Finally, the spacing between the partition plates 202 after adjustment is equal, and a pushing component is provided on the frame 1.

[0038] like Figure 7-Figure 11As shown, the pushing assembly includes a rotating rod 301, a rack frame 302 and a gear 303. The rotating rods 301 are rotatably connected to the left and right sides of the bottom of the two frames 1. The rack frames 302 are slidably connected to the leftmost limit frame 101 and the rightmost limit frame 101. The inner sides of the rotating rods 301 are rotatably connected to the rack frames 302 on the same side. The two rotating rods 301 form an eight-shaped structure. The middle part of the spiral shaft 204 is connected to two gears 303, and the rack frames 302 are meshed with the two gears 303 on the same side.

[0039] like Figure 1 and Figure 13-Figure 15 As shown, the transmission assembly includes a support block 401, a worm 402, a knob 403, a bidirectional lead screw 404 and a worm wheel 405. The support block 401 is symmetrically welded on the front side wall of the front frame 1. The worm 402 is rotatably connected between the two support blocks 401. The left and right ends of the worm 402 are connected to the knob 403. The second limit frame 101 and the fourth limit frame 101 from the left to the right are both rotatably connected with the bidirectional lead screw 404. The bidirectional lead screw 404 is threadedly connected to the two sliders 103 on the same side. The front side of the bidirectional lead screw 404 is welded with a worm wheel 405, and the worm wheel 405 is meshed with the worm 402.

[0040] When laying the cable 102, the device can be installed on a pre-set bracket through the installation groove 104, and the device can be fixed at a high place. The cable 102 can be laid after installation, or the cable 102 can be laid first and then the device can be fixed. When laying the cable 102, the cable 102 is passed into the frame 1, and the cable 102 is separated on the limit frame 101 through the separation plate 202 and the limit block 201, which is conducive to limiting the cable 102 and ensuring the stability and neatness of the cable 102. For cables 102 with different diameters, the separation plate 202 can be adjusted. The spacing between the plates 202 is adjusted. When adjusting, the knob 403 is first turned to drive the worm 402 to rotate, and the worm 402 drives the worm wheel 405 to rotate. The worm 402 will drive the bidirectional screw 404 to rotate, so that the bidirectional screw 404 drives the slider 103 on the corresponding side to move outward. As the frame 1 moves, all the sliders 103 are moved outward. The outward movement of the frame 1 will pull the rotating rod 301 to rotate. The rotating rods 301 on the front and rear sides form an eight-shaped structure. The rotation of the rotating rod 301 can push the rack 302 to move inward, so that the rack 302 drives the gear 303 As the spiral shaft 204 rotates, the arc groove 205 will rotate and push the corresponding partition plate 202 to move outward. Due to the different sizes of the arc surface angles of the arc groove 205, the moving distances between the partition plates 202 are different. The larger the angle of the arc groove 205, the larger the moving distance of the partition plate 202. The arc groove 205 moves the partition plate 202 outward to adjust the spacing between the partition plates 202. The limit block 201 moves with the frame 1. The moving distance of the partition plate 202 depends on the moving distance of the frame 1. When the spacing between the partition plates 202 is adjusted to correspond to the size of the cable 102, the stop block 201 is moved. Stop turning the knob 403, and the spacing between the partition plates 202 after final adjustment will be equal. This adjustable method can be suitable for cables 102 of different diameters, is more practical, and can ensure the neatness between the cables 102, which is convenient for operation during later maintenance. Similarly, if it is necessary to reduce the spacing between the partition plates 202, reverse the above operation and reverse the knob 403, so that the two frames 1 can be moved closer to each other, and at the same time, the spiral shaft 204 and the arc groove 205 can be reversed, so that the front and rear partition plates 202 can be moved inward, and the spacing between the two partition plates 202 can be adjusted.

[0041] like Figure 1 and Figure 16-Figure 17As shown, the bridge frame also includes a support frame 501, an articulated frame 1 502, an articulated frame 2 503, a buffer spring 504, a torsion spring 505 and a telescopic roller 506. The left and right ends of the two frames 1 are connected to the support frame 501 by bolts. The two front and rear symmetrical support frames 501 are slidably telescopically connected. The support frame 501 is rotatably connected to the articulated frame 1 502, and the articulated frame 1 502 is rotatably connected to the articulated frame 2 503. The buffer spring 504 is connected between the articulated frame 1 502 and the support frame 501 on the same side, and the torsion spring 505 is connected between the articulated frame 2 503 and the articulated frame 1 502 on the same side. The telescopic roller 506 is rotatably connected between the two front and rear symmetrical articulated frames 1 502, and the two telescopic rollers 506 are rotatably connected between the two front and rear symmetrical articulated frames 2 503.

[0042] When the cable 102 is laid in the frame 1, the two ends of the cable 102 will hang on both sides of the frame 1, the telescopic roller 506 plays a role in supporting the two ends of the cable 102, and the buffer spring 504 plays a buffering role. The articulated frame 1 502 and the articulated frame 2 503 will rotate due to the gravity and angle of the two ends of the cable 102. The torsion spring 505 is used for buffering and resetting. The setting of the rotation connection of the telescopic roller 506 makes the cable 102 move more smoothly when the cable 102 moves. The setting of the articulated frame 1 502 and the articulated frame 2 503 It can avoid the situation where the angle between the two ends of the cable 102 and the frame 1 is too small, which will cause the cable 102 to bend greatly. If there is no support at both ends of the cable 102, the two ends of the cable 102 hang on both sides of the frame 1, the angle is too small, the angle is easy to wear, and the internal wire core is easy to break. The articulated frame 1 502 and the articulated frame 2 503 support the two ends of the cable 102, which can expand the bending angle of the two ends of the cable 102. At the same time, when the frame 1 moves to adjust the spacing, the telescopic roller 506 can be telescopic to adapt to the adjustment of the frame 1.

[0043] like Figure 1 and Figure 2 As shown, the bridge frame also includes a dustproof plate 6. The top of the frame 1 is connected with a dustproof plate 6 by bolts for protecting the cable 102 from dust. The dustproof plates 6 are staggered up and down. When the distance between the two frames 1 is increased, the upper and lower dustproof plates 6 will also move staggered.

[0044] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
