Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, and in particular to a cantilevered detachable aerial work platform for steel structure installation. Background Technology
[0002] Steel components refer to steel structural composite components that can bear and transmit loads, made of steel plates, angle steel, channel steel, I-beams, welded or hot-rolled H-beams cold-bent or welded and connected by connectors. With the rapid development of society, steel components are widely used in various industries. In my country's engineering construction field, a large number of projects often adopt steel structures as the main structural form. Since steel structures are often quite tall, aerial work platforms are needed for high-altitude operations during installation and construction.
[0003] Existing aerial work platforms are generally fixed to angle steel plates on steel structures by connecting bolts. However, after installation, the connecting bolts are usually directly exposed to the external environment. Rainwater will come into direct contact with the connecting bolts, causing them to oxidize and rust, which reduces their service life and poses certain safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a cantilevered, detachable aerial work platform for steel structure installation, in order to solve at least one of the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cantilevered detachable aerial work platform for steel structure installation, comprising angle steel plates with two threaded grooves on their tops, a steel plate base on the top of the two angle steel plates, a guardrail on the top of the steel plate base, four threaded rods threadedly installed on the steel plate base, the bottom ends of the four threaded rods extending into the four threaded grooves and engaging with the inner walls of the four threaded grooves, protective tubes movably sleeved on the four threaded rods, and the four protective tubes fixedly connected to the steel plate base, grooves on the tops of the four threaded rods, elastic ropes fixedly installed on the bottom inner walls of the four grooves, limit plates fixedly installed on the tops of the four elastic ropes, and the four limit plates slidably connected to the inner walls of the four grooves, rotating rods rotatably installed on the tops of the four limit plates, and the tops of the four rotating rods extending outside the corresponding protective tubes, and rotating sealing covers fixedly installed on the tops of the four rotating rods.
[0006] Preferably, two limiting grooves are formed on the inner walls of the four grooves, and the two sides of the four limiting plates extend into the two limiting grooves and are slidably connected to the inner walls of the corresponding limiting grooves.
[0007] Preferably, the top of each of the four limiting plates is provided with a rotating groove, the bottom end of each of the four rotating rods extends into the four rotating grooves and is fixedly fitted with a bearing, and the outer ring of each of the four bearings is fixedly connected to the inner wall of the four rotating grooves.
[0008] Preferably, a flange plate is fixedly installed inside each of the four protective pipes, and each of the four flange plates has an opening. An isolation net is fixedly installed inside each of the four openings, and a desiccant is placed on the top of each of the four flange plates.
[0009] Preferably, the top of each of the two angle steel plates is provided with a positioning groove, and four positioning posts are fixedly installed at the bottom of the steel plate base, with the bottom ends of the four positioning posts extending into the four positioning grooves respectively.
[0010] Preferably, the elastic drawstring is made of spandex.
[0011] The beneficial effects of this utility model are as follows:
[0012] In this invention, a working platform is formed by a steel plate base and a guardrail. An elastic rope ensures the rotating sealing cover remains tightly fitted to the protective pipe without external force. The protective pipe and rotating sealing cover together form a protective shield for the threaded rod. A desiccant keeps the threaded rod in a dry environment, further extending its service life. The process involves first moving the rotating sealing cover upwards to separate it from the protective pipe, then rotating the sealing cover counterclockwise to rotate the threaded rod counterclockwise and move it upwards out of the thread groove. This allows for quick and easy removal of the working platform from the angle steel plate. The process is simple, fast, and highly efficient. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides, for example Figure 1-5 The cantilevered, detachable aerial work platform for steel structure installation shown includes angle steel plates 1 with two threaded grooves on their tops. A steel plate base 2 is mounted on top of the angle steel plates 1, and a guardrail 16 is mounted on top of the steel plate base 2. Four threaded rods 5 are threaded onto the steel plate base 2, with the bottom ends of the four threaded rods 5 extending into the four threaded grooves and engaging with the inner walls of the grooves. Protective tubes 10 are movably fitted onto each of the four threaded rods 5, and all four protective tubes 10 are fixedly connected to the steel plate base 2. Grooves 6 are formed at the top of each of the four threaded rods 5, and elastic ropes 8 are fixedly installed on the bottom inner walls of each of the four grooves 6. To improve the service life of the elastic ropes 8, they are made of spandex. Limiting plates 7 are fixedly installed at the top of each of the four elastic ropes 8. Four limiting plates 7 are slidably connected to the inner walls of four grooves 6 respectively. Rotating rods 9 are rotatably installed on the top of each of the four limiting plates 7. In order to rotate the rotating rods 9 on the limiting plates 7, rotating grooves are opened on the top of each of the four limiting plates 7. The bottom ends of the four rotating rods 9 extend into the four rotating grooves and are respectively fixedly fitted with bearings. The outer rings of the four bearings are fixedly connected to the inner walls of the four rotating grooves. The bearings make the rotating rods 9 rotate more stably on the limiting plates 7. The top ends of the four rotating rods 9 extend to the corresponding protective tubes 10. Rotating sealing covers 11 are fixedly installed on the top ends of the four rotating rods 9 respectively. The protective tubes 10 and rotating sealing covers 11 form a protective cover to protect the threaded rod 5, so that rainwater cannot come into contact with the threaded rod 5, thereby protecting the threaded rod 5.
[0021] In order for the rotation of the limiting plate 7 to drive the threaded rod 5, two limiting grooves are respectively opened on the inner wall of the four grooves 6, and the two sides of the four limiting plates 7 extend into the two limiting grooves and slide with the inner wall of the corresponding limiting groove.
[0022] In order to absorb water vapor inside the protective tube 10 and keep the threaded rod 5 in a dry environment, thereby further improving the service life of the threaded rod 5, flange flanges 12 are fixedly installed inside the four protective tubes. Each of the four flange flanges 12 has an opening, and an isolation net 14 is fixedly installed inside each of the four openings. A desiccant 13 is placed on the top of each of the four flange flanges 12.
[0023] In order to quickly align the threaded rod 5 with the threaded groove and then quickly fix the steel plate base 2 on the angle steel plate 1, the top of the two angle steel plates 1 are respectively provided with positioning grooves 3, and the bottom of the steel plate base 2 is respectively fixedly installed with four positioning posts 4, and the bottom ends of the four positioning posts 4 extend into the four positioning grooves 3 respectively.
[0024] The working principle of the cantilevered detachable aerial work platform for steel structure installation provided by this utility model is as follows: A work platform is formed by the steel plate base 2 and the guardrail 16. Workers carry out construction work inside the work platform. In the initial state, the elastic rope 8 is in a stretched state. The elastic rope 8 keeps the rotating sealing cover 11 tightly attached to the protective pipe 10 without being subjected to other external forces, thus blocking the protective pipe 10. The protective pipe 10 and the rotating sealing cover 11 form a protective cover to protect the threaded rod 5, preventing rainwater from contacting the threaded rod 5. To protect the threaded rod 5, desiccant 13 absorbs the water vapor entering the protective cover 10, keeping the threaded rod 5 in a dry environment and further improving its service life. When the work platform needs to be disassembled, first move the rotating sealing cover 11 upward to separate it from the protective tube 10, then rotate the rotating sealing cover 11 counterclockwise to drive the rotating rod 9 to rotate. The rotating rod 9 drives the limiting plate 7 to rotate, and the limiting plate 7 drives the threaded rod 5 to rotate counterclockwise and move upward out of the thread groove, thereby quickly disassembling the work platform from the angle steel plate 1. The process is simple, fast, and efficient.
[0025] Compared with related technologies, the cantilevered detachable aerial work platform for steel structure installation provided by this utility model has the following beneficial effects: a work platform is formed by the steel plate base 2 and the guardrail 16; the elastic rope 8 keeps the rotating sealing cover 11 tightly attached to the protective pipe 10 without being subjected to other external forces; the protective pipe 10 and the rotating sealing cover 11 form a protective cover to protect the threaded rod 5; the desiccant 13 keeps the threaded rod 5 in a dry environment, further improving the service life of the threaded rod 5; by first moving the rotating sealing cover 11 upward to separate it from the protective pipe 10, and then rotating the rotating sealing cover 11 counterclockwise to drive the threaded rod 5 to rotate counterclockwise and move upward out of the thread groove, the work platform can be quickly disassembled from the angle steel plate 1. The process is simple, fast and efficient.
