Description

Technical Field

[0001] The utility model relates to the field of high-altitude construction, in particular to a high-altitude construction platform. Background Art

[0002] In order to meet pollution discharge requirements during the production process, steel mills will install pollution reduction devices such as exhaust gas treatment valves at the outlet end of the exhaust pipe. The height of such exhaust pipes is often as high as tens of meters. The installation of such pollution reduction structures involves high-altitude operations. Since exhaust pipes are often densely arranged, the spacing between exhaust pipes is small. The existing high-altitude brackets are limited by their own floor space and are not easy to install between exhaust pipes. There are also some liftable aerial work platforms, but since the work platforms cannot be sent into the gaps between multiple exhaust pipes, it is inconvenient for workers to operate on the exhaust pipes.

[0003] The utility model with Chinese patent publication number: CN117365132A, publication date: 2024-01-09 discloses a multifunctional mobile high-altitude retractable cantilever work platform. The work platform mentioned in the patent can meet the needs of high-altitude operations, but this type of work platform is not suitable for a narrow working environment. For example, when faced with densely arranged exhaust pipes, workers on this work platform can only work on the outer exhaust pipes, and it is inconvenient to take into account the exhaust pipes located inside. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a high-altitude construction platform that is easy to install in a small space and has the advantage of a simple structure.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides a high-altitude construction platform, comprising an upper clamp and a lower clamp installed on an exhaust pipe, wherein a plurality of support rods are hingedly connected to the outer wall of the upper clamp, and the plurality of support rods are spaced apart along the circumference of the exhaust pipe; a telescopic element is hingedly connected to the outer wall of the lower clamp for driving each support rod to flip up and down; the support rod is provided with a slide groove extending along its own length, and a slide key is provided in the slide groove, and the telescopic end of the telescopic element is connected to the slide key on the corresponding support rod; the support rod has an expanded state during operation and a contracted state after storage; when the support rod is in the expanded state, the plurality of support rods cooperate to form a support frame for supporting the pedal assembly. The support rod is in a contracted state before installation, at which time it occupies less space and is convenient for installation in a narrow gap; when the support rod is in the expanded state, the top surface of the support rod is horizontal, which is convenient for laying the pedal assembly.

[0006] Preferably, four support rods are provided, and the four support rods are evenly distributed along the circumference of the upper hoop.

[0007] Preferably, the aerial construction platform includes an abutment rod for stabilizing the telescopic element. One end of the abutment rod is hinged to the fixed portion of the telescopic element, and the other end of the abutment rod is free. When the support rod is in the extended state, the free end of the abutment rod abuts against the side wall of the exhaust pipe. The provision of the abutment rod further increases the stability of the telescopic element, thereby increasing the stability of the construction platform during use.

[0008] Preferably, the support rod is an angle iron rod, and the support rod includes a horizontal rod body and a vertical rod body. The horizontal rod body is located above the vertical rod body, and the sliding groove is provided on the vertical rod body.

[0009] Preferably, a mounting block is provided on the outer wall of the upper clamp, and the end of the vertical rod body is hinged on the mounting block.

[0025] The present application provides a high-altitude construction platform suitable for high-altitude operations in small installation spaces, with the characteristics of simple structure and convenient installation. In the following embodiments, up and down refer to up and down along the axis of the exhaust pipe 100.

[0026] like Figures 1 to 7As shown, the high-altitude construction platform of the present invention comprises an upper hoop 1 and a lower hoop 2 which are detachably mounted on the exhaust pipe 100. A plurality of support rods 3 are hingedly connected to the side wall of the upper hoop 1, and the plurality of support rods 3 are distributed at intervals along the circumference of the exhaust pipe 100; a telescopic element 4 which drives each support rod 3 to flip up and down is hingedly connected to the side wall of the lower hoop 2; a slide groove 321 extending along the length direction of the support rod 3 is provided, and a slide key 322 is provided in the slide groove 321, and the telescopic end of the telescopic element 4 is connected to the slide on the corresponding support rod 3. The support rod 3 has an extended state during operation and a retracted state after storage. When the support rod 3 is in the extended state, multiple support rods 3 cooperate to form a support frame for supporting the pedal assembly. At this time, the top surface of the support rod 3 coincides with the horizontal plane, and the sliding key 322 is located at the end of the slide groove 321 away from the exhaust pipe 100. When the support rod 3 needs to be switched to the retracted state, the pedal assembly must first be removed from the top surface of the support rod 3 to ensure that the sliding key 322 can slide to the end of the slide groove 321 close to the exhaust pipe 100. It can be understood that the support rod 3 in the retracted state occupies less space, making it easier to install it on the exhaust pipe 100.

[0027] During actual installation, first install the upper clamp 1 and the lower clamp 2 on the exhaust pipe 100, then install the telescopic element 4 on the lower clamp 2, and then install the support rod 3 in a retracted state on the upper clamp 1. At this time, the support rod 3 is tilted downward and occupies less space. After the support rod 3 is installed in place, connect the telescopic end of the telescopic element 4 to the sliding key 322, then open the telescopic element 4 to drive the support rod 3 to the expanded state, and finally lay the pedal (not shown) on the top surface of the support rod 3. At this time, the installation of the construction platform is completed. When the construction platform needs to be removed, the above steps can be reversed, which will not be repeated here.

[0028] like Figure 1 and Figure 6 As shown, there are four support rods 3 and four telescopic elements 4. The four support rods 3 are evenly distributed along the circumference of the upper clamp 1, and the four telescopic elements 4 are evenly distributed on the outer wall of the lower clamp 2. The telescopic elements 4 correspond one-to-one with the support rods 3, and the telescopic elements 4 drive the corresponding support rods 3 to swing to achieve the switching between the expanded state and the retracted state. The construction platform also includes four abutment rods 5, which correspond one-to-one with the telescopic elements 4. One end of the abutment rod 5 is hinged to the fixed part of the corresponding telescopic element 4, and the other end of the abutment rod 5 is a free end. When the support rod 3 is in the expanded state, the free end of the abutment rod 5 abuts against the side wall of the exhaust pipe 100 and the abutment rod 5 is in a horizontal state. The telescopic element 4 is a linear drive element such as a cylinder or an electric push rod that can realize the telescopic function. There is no limitation here. The appropriate telescopic element 4 is selected according to actual needs. The telescopic element 4 in this embodiment is a cylinder, and one end of the abutment rod 5 is hinged to the rod body of the cylinder. By providing the abutment rod 5, the stability of the construction platform during use is further increased.

[0029] like Figures 2 to 5 As shown, the support rod 3 is an angle iron rod, comprising a horizontal rod body 31 and a vertical rod body 32. The horizontal rod body 31 is positioned above the vertical rod body 32, and a slide groove 321 is provided on the vertical rod body 32. The angle iron rod has a simple structure and can be processed into various load-bearing components according to different needs. It can also serve as a connecting member, making it suitable for manufacturing the support rod 3. In addition, the top surface of the horizontal rod body 31 of the support rod 3 is horizontal, suitable for supporting the pedals.

[0030] like Figure 7 As shown, the side wall of the upper clamp 1 is provided with a mounting block 13, the longitudinal section of the mounting block 13 is rectangular, and the end of the vertical rod body 32 of the support rod 3 is hinged on the mounting block 13; when the support rod 3 is in the expanded state, the bottom surface of the horizontal rod body 31 of the support rod 3 can fit with the top surface of the mounting block 13. At this time, the support rod 3 remains in a horizontal position. In this way, the mounting block 13 is not only used for the installation of the support rod 3, but also serves as a positioning member for the expanded state of the support rod 3, ensuring that the support rod 3 can accurately swing to a horizontal position; in this embodiment, the upper clamp 1 includes two first clamp bodies 11 arranged symmetrically on the left and right, and the first clamp body 11 includes a semi-ring and a first folded edge 12 formed at both ends of the semi-ring; after the two first clamp bodies 11 are butt-jointed and sleeved on the exhaust pipe 100, they are clamped and fixed by a first bolt assembly passing through the two opposite first folded edges 12. In this solution, the two support rods 3 are respectively rotatably connected to the two first folding edges 12 of the first hoop body 11, and the screw of the first bolt assembly serves as the rotating shaft of the support rod 3. The folding edge limits the rotation range of the support rod 3 and plays the same role as the mounting block 13. Similarly, the lower hoop 2 includes two second hoop bodies 21 that are symmetrically arranged. The second hoop body 21 includes a half ring and two second folding edges 22. The two second folding edges 22 are respectively connected to the two ends of the half ring. The two second hoop bodies 21 are passed through the second bolt assembly through the two relative second folding edges 22 and are sleeved on the exhaust pipe 100. The two telescopic elements 4 are respectively rotatably connected to the two second folding edges 22 of the second hoop body 21. It should be noted that the half rings of the two first hoop bodies 11 half rings can be split or hinged together. The improvement of this embodiment is that the folding edge of the first hoop body 11 not only plays the role of connecting the two half rings, but also can serve as the mounting block 13, and the connection mode of the two first hoop bodies 11 is not restricted.

[0031] The pedal assembly includes a plurality of pedals (not shown), such as Figure 4 As shown, the pedal includes a connecting rod 6, which is provided with a notch 61, which is adapted to the support rod 3. In this embodiment, the connecting rod 6 is inserted into the support rod 3 through the notch 61, and then the connecting rod 6 is fixed to the support rod 3 by a bolt structure.

[0032] The top surfaces of the multiple pedals are all provided with an anti-skid layer (not shown). By providing the anti-skid layer, the friction on the pedals is increased when the workers are working on rainy days, thereby improving the safety of the construction platform.

[0033] like Figure 1 As shown, the four support rods 3 are detachably provided with vertical rods 7, which are used to install fences (not shown). By installing fences, the safety of the construction platform is further improved. In this embodiment, the fence is a sheet-like object such as a mesh or a baffle that can close the gap between two adjacent vertical rods 7 to prevent construction workers from falling from the platform, thereby improving construction safety.

[0034] Now, a specific example of its application on the exhaust pipe 100 is given: first, the upper clamp 1 and the lower clamp 2 are installed on the exhaust pipe 100, and then the support rod 3 is installed on the upper clamp 1 in a retracted state. At this time, the support rod 3 is tilted downward, taking up less space, reducing the space requirement when installing the construction platform. Then, the cylinder is installed on the lower clamp 2 and the telescopic rod of the cylinder is connected to the sliding key 322. Then, the abutment rod 5 is installed on the cylinder body of the cylinder. The cylinder is turned on to put the support rod 3 in the expanded state. Then, the staff manually rotates the abutment rod 5 so that the free end of the abutment rod 5 abuts against the side wall of the exhaust pipe 100. Finally, the pedal assembly is installed on the top surface of the support rod 3 and fixed with a bolt structure. In addition, the abutment rod 5 supports the cylinder along the radial direction of the upper clamp 1, thereby enhancing the support strength of the cylinder on the support rod 3.

[0035] To sum up, the support rod 3 of the present invention has a retracted state that occupies less space, which is convenient for installing the high-altitude construction platform in a narrow space; the expanded state and the retracted state of the support rod 3 are switched by a cylinder, which reduces the involvement of manpower and reduces the installation risk; finally, the present invention has a simple structure, a low cost, and is easy to promote and use.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
