[0001] This utility model relates to the field of elevator shaft platform technology, specifically a telescopic platform beam for a shaft platform. Background Technology

[0002] An elevator shaft is the shaft through which elevators are installed. In the construction of existing building shaft structures, an operating platform needs to be built. However, traditional elevator shaft platforms have limited adaptability, requiring custom-sized steel platform frames or main beams. This makes them unsuitable for elevator shafts of different sizes, and custom-sized platforms are not conducive to reuse, making the turnover process cumbersome. Therefore, we need to propose a telescopic platform beam for elevator shaft platforms. Utility Model Content

[0003] The purpose of this utility model is to provide a telescopic platform beam for a well platform. Through the plug-in mating structure of the male and female ends of the main beam, combined with the positioning holes and pin fixing method, the platform length can be quickly adjusted, which can flexibly adapt to the construction needs of different well diameters or platform spans, greatly improving construction efficiency. It also allows the main beam to be reused, and the reduction in size greatly reduces the cumbersomeness of transportation, thus solving the problems mentioned in the background art.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides: a telescopic platform beam for a well platform, including a male main beam 2 and a female main beam 4 assembled with the male main beam 2 to form the main beam 1 of the platform; the male main beam 2 is composed of a male H-beam 6, a reinforcing rib 7, and a male channel steel 12 connected to one end of the male H-beam 6; a main beam pressure plate 9 is bolted to the end of the male H-beam 6; the female main beam 4 is composed of a female channel steel 16, a fixing rib 17, and a female welded steel plate 19 connected to the top of the female channel steel 16; a female base welded plate 20 is connected to the bottom of the female channel steel 16; the male H-beam 6 is movably inserted into the interior of the female channel steel 16; a second pin 23 for controlling the length of the main beam 1 of the platform is installed on the surfaces of the male H-beam 6 and the female channel steel 16; a male hanging head 3 and a female beam hanging head 5 are respectively provided at the ends of the male channel steel 12 and the female channel steel 16.

[0020] It is worth noting that through the coordinated arrangement of structures such as the male head H-beam 6, L-shaped limiting rib plate 8, main beam pressure plate 9, female head channel steel 16, female head welded steel plate 19, and female head base welded plate 20, and through the insert-type mating structure of the male and female heads of the main beam, combined with the positioning hole and pin shaft fixing method, the platform length can be quickly adjusted. This allows for flexible adaptation to the construction needs of different well diameters or platform spans, significantly improving construction efficiency. Furthermore, the main beam can be reused, while greatly reducing the cumbersomeness of transportation.

[0021] The reinforcing ribs 7 are fixedly welded to both sides of the male head H-beam 6. The surface of the male head H-beam 6 is fixedly welded with L-shaped limiting ribs 8, which assist in the adjustment and limiting of the main beam female head 4. The bottom of the main beam pressure plate 9 is movably connected to the top of the female head channel steel 16. The top of the male head H-beam 6 is provided with mounting holes 10, and the male head channel steel 12 is connected with the first lifting spot welded plate 13.

[0022] Specifically, the symmetrical welding design of the reinforced rib 7 and L-shaped limiting rib 8 effectively disperses stress, improves the composite load-bearing structure of the platform main beam 1, and ensures the overall torsional resistance. Furthermore, the L-shaped limiting rib 8, in conjunction with the bottom of the female head channel steel 16, acts as a limiting element during adjustment. The limiting structure, where the mounting hole 10 of the main beam pressure plate 9 cooperates with the L-shaped limiting rib 8, ensures the structural stability during adjustment.

[0023] The male head H-beam 6 has evenly distributed positioning holes 11 on its surface, and the female head channel steel 16 has assembly holes 22 that mate with the positioning holes 11 on its surface. The second pin 23 is movably inserted into the positioning holes 11 and the assembly holes 22.

[0024] Furthermore, based on the size requirements of the elevator shaft, after adjustment inside the main beam female head 4 via the male head 2 of the main beam, the second pin 23 passes through the assembly hole 22 and is fixed inside the positioning hole 11, thereby realizing the telescopic adjustment function of the platform main beam 1, further improving the adjustment accuracy, and ensuring the convenience of using the platform main beam 1 in different elevator shafts.

[0025] The female head base welding plate 20 is bolted with a first pin 21, and the bottom of the female head welding steel plate 19 is movably connected to the top of the male head H-beam 6. The fixing rib 17 is fixedly welded between the female head channel steels 16, and the inner wall of the female head channel steel 16 is provided with a second lifting point welding plate 18.

[0026] The first pin 21 connects the female head base welding plate 20 and limits the bottom of the male head H-beam 6 of the main beam male head 2 when the male head 2 is inserted into the female head 4 of the main beam. The female head welding steel plate 19 is a limiting structure that cooperates with the first pin 21. It cooperates with the L-shaped limiting rib plate 8 on the surface of the male head H-beam 6 and the main beam pressure plate 9 to effectively ensure the stability of the expansion and contraction adjustment of the male head 2 and the female head 4 of the main beam.

[0027] In addition, the male head bracket 3 includes a head bracket side plate 14 and an end bending connecting plate 15, which is fixedly connected to the end of the head bracket side plate 14. The female beam bracket 5 has the same structure as the male head bracket 3. The setting of the first lifting spot welding plate 13 and the second lifting spot welding plate 18 simplifies the lifting process, facilitates the quick docking of the ends of the male head bracket 3 and the female beam bracket 5 with other structures, and further reduces the amount of on-site welding work.

[0028] The main beam's male and female ends are fitted together by a plug-in structure and fixed by a second pin 23 through positioning holes 11 and assembly holes 22, enabling rapid telescopic adjustment. This adapts to different well diameters or platform span requirements, significantly improving construction efficiency and reducing customization costs. Furthermore, the L-shaped limiting rib plate, in conjunction with the main beam pressure plate and the synergistic effect of the female end welded steel plate 19 and the first pin 21 structure, prevents excessive displacement of the male end H-beam within the female end channel steel. It also enhances the dynamic fit between the main beam pressure plate 9 and the top of the channel steel, strengthening bending resistance and ensuring the structural rigidity of the platform in telescopic mode. This guarantees stable and safe adjustment. The telescopic adjustment feature further improves the reusability of the platform's main beam 1. Additionally, in the retracted state, the platform's main beam 1 can be easily transported.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
