Description

Technical Field

[0001] This utility model relates to an overhead power line support, specifically a temporary overhead power line support for construction sites, and belongs to the field of temporary power supply technology. Background Technology

[0002] During the construction of offshore drilling platforms, the main purpose of using temporary overhead power line supports is to prevent electrical wires from directly contacting the platform deck, equipment, or seawater. This avoids damage to the insulation layer caused by friction and crushing, which could lead to safety hazards such as leakage and short circuits. Furthermore, these supports can regulate the routing of electrical wires, reducing obstruction to personnel movement and equipment handling. They also effectively reduce the direct corrosion of electrical wires by seawater and salt spray, extending the service life of temporary power lines and ensuring a safe and stable power supply during construction, providing reliable support for the operation of various equipment and tasks.

[0003] In existing technologies, temporary overhead power line supports, for ease of transport, mostly consist of two poles. During use, the two poles are connected by a connecting mechanism to increase the overall height of the support, allowing temporary power lines to be suspended. However, this design has significant limitations: it cannot be flexibly adjusted to meet the different overhead height requirements of the power lines in actual construction scenarios, such as avoiding equipment at different heights or adapting to space constraints in different work areas. This results in situations where a slightly higher or lower overhead height is needed, either the support is too high, leading to resource waste and operational inconvenience, or too low, failing to meet the required safe distance between the power lines and the ground, affecting construction efficiency. Furthermore, it is difficult to adapt to the complex and ever-changing construction environment of offshore drilling platforms. Therefore, this paper proposes a new type of temporary overhead power line support for construction sites. Utility Model Content

[0004] In view of this, the present invention provides a temporary overhead power line support for construction sites to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a temporary overhead power line support for construction sites includes a main component, wherein the main component includes a support sleeve, a limiting strip, an adjusting screw, a lifting support rod, a limiting groove, a worm gear, a handwheel, and a scale.

[0006] The bottom end of the lifting support rod is located inside the support sleeve. The limiting strip is symmetrically and fixedly connected to the inner side wall of the support sleeve. Limiting wheels are installed at equal intervals on the limiting strip. The limiting grooves are symmetrically opened on the outer side wall of the lifting support rod. The bottom end of the adjusting screw is fixedly connected to a worm gear. The outer side wall of the worm gear meshes with the outer side wall of the worm gear. One end of the worm gear is fixedly connected to a handwheel. The lifting support rod is threaded to the outer side wall of the adjusting screw. A scale is fixedly connected to the bottom of the outer side wall of the lifting support rod. The scale is fixedly connected to the outer side wall of the support sleeve.

[0007] More preferably, the limiting strip is slidably connected inside the limiting groove and is attached to the inner wall of the limiting groove by the limiting wheel.

[0008] More preferably, the bottom end of the worm gear is rotatably connected to the inner bottom wall of the support sleeve.

[0009] More preferably, the bottom of the outer wall of the support sleeve is provided with an opening and a sealing cover is fixedly connected thereto, and the worm gear is rotatably connected to the inside of the sealing cover.

[0010] More preferably, the outer wall of the support sleeve is provided with a through groove, and the scale slides inside the through groove and is positioned corresponding to the scale.

As the lifting support rod moves, its height can be precisely adjusted by referring to the scale and graduations, allowing the wire to be suspended at different heights. Compared to existing technologies, this invention, through the coordination of the handwheel, worm gear, worm wheel, adjusting screw, and lifting support rod, allows for flexible adjustment of the lifting support rod's height according to the different suspension heights required for the wire, improving construction efficiency and adapting to the complex and varied construction environment of offshore drilling platforms.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5As shown, this utility model embodiment provides a temporary overhead power line support for construction sites, including a main component 101. The main component 101 includes a support sleeve 11, a limiting strip 13, an adjusting screw 14, a lifting support rod 16, a limiting groove 17, a worm gear 19, a handwheel 21, and a scale 22.

[0027] The bottom end of the lifting support rod 16 is located inside the support sleeve 11. The limiting strip 13 is symmetrically fixedly connected to the inner side wall of the support sleeve 11. Limiting wheels 12 are installed at equal intervals on the limiting strip 13. The limiting groove 17 is symmetrically opened on the outer side wall of the lifting support rod 16. The limiting strip 13 is slidably connected to the inside of the limiting groove 17 and fits against the inner wall of the limiting groove 17 through the limiting wheel 12. The lifting support rod 16 contacts the limiting strip 13 through the limiting wheel 12. With the help of the limiting strip sleeve 13 and the limiting wheel 12, the lifting support rod 16 can be effectively supported and guided.

[0028] When the lifting support rod 16 moves up and down, the limit wheel 12 rotates accordingly, thereby significantly reducing the friction during the lifting process and ensuring that the entire lifting process is smooth and unobstructed.

[0029] A worm gear 20 is fixedly connected to the bottom end of the adjusting screw 14. The outer wall of the worm 19 is meshed with the outer wall of the worm gear 20. A handwheel 21 is fixedly connected to one end of the worm 19. The lifting support rod 16 is threadedly connected to the outer wall of the adjusting screw 14. The bottom end of the worm gear 20 is rotatably connected to the inner bottom wall of the support sleeve 11. By rotating the handwheel 21, the handwheel 21 drives the worm 19 to rotate, the worm 19 drives the worm gear 20 to rotate, and the worm gear 20 drives the adjusting screw 14 to rotate. The adjusting screw 14 drives the lifting support rod 16 to move up and down through the threads on its surface, thereby realizing the height adjustment of the lifting support rod 16.

[0030] A scale 18 is fixedly connected to the bottom of the outer wall of the lifting support rod 16, and a scale 22 is fixedly connected to the outer wall of the support sleeve 11. A through groove 23 is opened on the outer wall of the support sleeve 11. The scale 18 slides inside the through groove 23 and its position corresponds to the scale 22. When the lifting support rod 16 moves up and down, it drives the scale 18 to slide in the through groove 23. By referring to the scale line next to the scale 18, the height of the lifting support rod 16 can be accurately adjusted.

[0031] In one embodiment, the bottom of the outer wall of the support sleeve 11 is provided with an opening and a sealing cover 15 is fixedly connected thereto. The worm gear 19 is rotatably connected to the inside of the sealing cover 15, thereby limiting the position of the worm gear 19.

[0032] By setting an opening, the transmission mechanism inside the support sleeve 11 can be easily inspected or maintained. The sealing cover 15 is fixed to the support sleeve 11 with screws, and the opening can be exposed after disassembly.

[0033] In one embodiment, a suspended plate 33 is fixedly connected to the top of the lifting support rod 16, and wire limiting frames 34 are installed at equal intervals on the upper surface of the suspended plate 33. The top of the wire limiting frame 34 is provided with an opening to facilitate the placement and removal of wires.

[0034] In one embodiment, a base 31 is fixedly connected to the bottom end of the support sleeve 11, and a magnet 32 ​​is embedded in the lower surface of the base 31. When the overhead support is used on an offshore drilling platform, since the working deck of the offshore drilling platform is made of steel, the base 31 can be attracted to the working deck of the offshore drilling platform by means of the magnet 32.

[0035] When this utility model is in operation: the entire overhead support is moved to the designated working position, the base 31 is placed on the working deck of the offshore drilling platform, the magnet 32 ​​is attracted to the working deck, the position of the overhead support is fixed, the wire is placed inside the wire limiting bracket 34, at this time the handwheel 21 is turned, the handwheel 21 drives the worm gear 19 to rotate, the worm gear 20 drives the adjusting screw 14 to rotate, the adjusting screw 14 drives the lifting support rod 16 to move through the thread on its surface, when the lifting support rod 16 moves, it drives the scale 18 to slide in the through groove 23, by referring to the scale line next to the scale 18, the height of the lifting support rod 16 can be accurately adjusted, and the wire can be suspended to different height positions;

[0036] Compared with the prior art, this utility model, through the cooperation of handwheel 21, worm gear 19, worm wheel 20, adjusting screw 14, lifting support rod 16 and other structures, can flexibly adjust the height of lifting support rod 16 according to the different overhead height required by the power line, which improves construction efficiency and can adapt to the complex and ever-changing construction environment of offshore drilling platforms; moreover, the limiting wheel 12 can reduce the friction of lifting support rod 16 during the lifting process, ensuring the smoothness of the entire lifting process.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
