[0002] Building electrical engineering is an applied discipline that uses electrical technology to create a humane living environment in a limited space. In building electrical construction, cables need to be installed on the roof of the building and then fixed with clips.

[0003] Since cables are long and heavy, in order to facilitate the installation of cables in building electrical construction, workers generally use a lifting platform with a cable conveyor on one side, wherein the lifting platform is used for workers to carry out construction, and the cable conveyor is used to vertically transport the cables placed on the ground to the roof. The cables are generally laid horizontally and close to the roof wall. The existing devices make it difficult to change the delivery angle of the vertically transported cables. Therefore, workers need to manually pull the cables to change the cable delivery direction when installing the cables, which is inconvenient. In view of this, we propose a cable installation device for building electrical construction. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figures 1 to 4 As shown, the utility model relates to a cable laying device for building electrical construction, comprising a lifting platform 1, a cable conveyor 2 and a steering mechanism 3 arranged on one side of the load-bearing end of the lifting platform 1. In the utility model, the lifting platform 1 is an existing device for lifting on the market, and the cable conveyor 2 is an existing device for cable conveying on the market.

[0023] like Figures 1 to 4 As shown, the steering mechanism 3 is arranged at the output end of the cable conveyor 2.

[0024] Specifically, Figure 1 , Figure 2As shown, the steering mechanism 3 includes an L-shaped mounting plate 301 and a mounting box 302 with an open bottom and top. The bottom surface of one end of the L-shaped mounting plate is fixedly mounted on the outer wall of one side of the output end of the cable conveyor 2 by screws. The mounting box 302 is arranged on the top of the output end of the cable conveyor 2. The mounting box 302 is fixedly connected with a rotating shaft 303 on the top surface of the side opposite to the L-shaped mounting plate 301. One end of the rotating shaft 303 is passed through the other end of the L-shaped mounting plate 301 and is fixedly connected with a worm gear 304. A worm 305 is meshed with the top of the worm gear 304. The two ends of the worm 305 are rotatably connected to the side of the other end of the mounting plate 301 through the mounting bearing, one end of the worm 305 is fixedly connected to a hand wheel A306, and both ends of the inner cavity of the mounting box 302 are movably connected to a pressure wheel 307; both sides of the mounting box 302 are provided with a slide groove 3021 connecting the inner cavity of the mounting box 302 and the outside, and both ends of the pressure wheel 307 are rotatably connected to a slider 3071 through a short shaft, and the slider 3071 is slidably connected to the slide groove 3021; ​​a bidirectional screw rod 308 is provided on the opposite side of the mounting box 302 and the L-shaped mounting plate 301, and the bidirectional screw rod 308 is provided on the opposite side of the mounting box 302 and the L-shaped mounting plate 301. The two ends of the screw rod 308 are rotatably connected to the two ends of the side of the L-shaped mounting plate 301 through the mounting bearings. The two ends of the bidirectional screw rod 308 are spirally sleeved with threaded sleeves 3081. One side of the threaded sleeve 3081 is fixedly connected to the surface of one side of the slider 3071, and one end of the bidirectional screw rod 308 is fixedly connected to a handwheel B309. The bottom of the installation box 302 is fixedly connected to a guide box 310 with an open bottom and top. After one end of the cable is moved out from the output end of the cable conveyor 2, it enters the installation box 302 from the bottom of the guide box 310 and is rotated to move the cable from the bottom of the guide box 310 to the installation box 302. 09 Rotate the bidirectional screw 308, which drives the two sliders 3071 to move in opposite directions through the threaded sleeve 3081, thereby driving the two pressure wheels 307 to press the two sides of the cable, and rotate the worm 305 through the handwheel A306. The worm 305 drives the worm wheel 304 to rotate, and the worm wheel 304 drives the installation box 302 to rotate around the rotating shaft 303 through the rotating shaft 303, thereby replacing manual adjustment of the cable conveying angle, and due to the self-locking principle of the worm wheel 304 and the worm 305, the angle will not be offset after adjustment.

[0025] Further, such as Figure 4 As shown, the inner cavity width of the guide box 310 gradually decreases from the output end of the cable conveyor 2 to the bottom of the installation box 302, which has a guiding effect and makes it easier for the cable to automatically enter the installation box 302 after coming out of the output end of the cable conveyor 2, without the need to manually pass the cable out of the installation box 302.

[0026] Further, if Figure 3As shown, a circular groove 3011 with the rotating shaft 303 as the center point is provided on the surface of the L-shaped mounting plate 301 on the opposite side of the mounting box 302, and arc-shaped sliding bars 3022 are provided at both ends of the mounting box 302 on the opposite side of the L-shaped mounting plate. The sliding bar 3022 is slidably connected to the circular groove 3011. When the rotating shaft 303 drives the mounting box 302 to rotate, the mounting box 302 drives the sliding bar 3022 to rotate in the circular groove 3011. At the same time, the sliding bar 3022 can provide support for the mounting box 302 to prevent the gravity of the mounting box 302 and the cable from being applied to the rotating shaft 303 all the time, causing the rotating shaft 303 to bend.

[0027] Working principle: This embodiment provides a cable laying device for building electrical construction. When in use, after one end of the cable is moved out from the output end of the cable conveyor 2, it enters the installation box 302 from the bottom of the guide box 310, and the bidirectional screw 308 is rotated by the handwheel B309. The bidirectional screw 308 drives the two sliders 3071 to move in opposite directions through the threaded sleeve 3081, thereby driving the two pressure wheels 307 to press the two sides of the cable, and the lifting platform 1 is driven to a suitable height by an external control mechanism, and the worm 305 is rotated by the handwheel A306. The worm 305 drives the worm wheel 304 to rotate, and the worm wheel 304 drives the installation box 302 to rotate around the rotating shaft 303 through the rotating shaft 303, and the installation box 302 drives the slide bar 3022 to rotate in the circular groove 3011, thereby replacing the manual adjustment of the cable conveying angle, and due to the self-locking principle of the worm wheel 304 and the worm 305, the angle will not be offset after adjustment.
