Description

Technical Field

[0001] This utility model relates to the field of elevator shaft construction technology, and more specifically, to an assembled elevator shaft protective steel component. Background Technology

[0002] With the acceleration of urbanization and the surge in the number of high-rise buildings, elevators, as the core facility for vertical transportation, have made shaft safety protection a key aspect of construction safety management during installation, maintenance, and renovation. In existing technologies, safety protection structures are typically required for large openings in elevator shafts and atriums at work sites to prevent accidents involving people or objects falling from heights. However, traditional protective structures often use welded or bolted monolithic steel structures. These structures have fixed dimensions and cannot be adapted to shafts or openings of different sizes, requiring on-site cutting and modification, leading to material waste. Furthermore, these structures are not disassembled, resulting in high transportation costs and limited reusability, which not only increases construction costs but also restricts the versatility and flexibility of the protective structures. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides an assembled elevator shaft protective steel component to solve the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] An assembled elevator shaft protective steel component includes two parallel main fixing rods. A plurality of telescopic stops are linearly and equally spaced between the main fixing rods. Each main fixing rod includes a first connecting part and a second connecting part at its two ends. The first connecting part and the second connecting part on any two main fixing rods can be detachably connected together. A fixing member is provided on the outer side of the main fixing rod away from the telescopic stops. Each telescopic stop includes an outer rod and inner rods at its two ends. A locking mechanism is provided at the intersection of each inner rod and the outer rod. The other end of the inner rod is connected to the main fixing rod.

[0006] Furthermore, the first docking part includes a first semi-threaded rod provided at the center of the end of the main fixing rod, the end of which is provided with a first opening, and a locking ring is movably provided on the first docking part.

[0007] Furthermore, the second mating part includes a second semi-threaded rod disposed at the center of the other end of the main fixing rod. The end of the second semi-threaded rod is provided with a second opening, the opening direction of which is opposite to that of the first opening. The diameter of the first semi-threaded rod and the diameter of the second semi-threaded rod are the same. After the two openings on any two main fixing rods overlap, the locking ring can be threadedly moved to the middle of the two.

[0008] Furthermore, the fixing component includes a lower fixing frame disposed on the outer side of the main fixing rod away from the telescopic stop bar, and a first threaded hole is provided on the outer side of the lower fixing frame near the bottom, and a clamping rod is movably disposed in the first threaded hole.

[0009] Furthermore, the clamping rod includes a first threaded rod threaded in the first threaded hole, with a clamping plate at one end near the telescopic stop and a rotating handle at the other end.

[0010] Furthermore, the clamp is provided with an anti-slip layer.

[0011] Furthermore, a groove is provided at the top of the inner rod.

[0012] Furthermore, anchor holes are linearly arranged on the top outer side of the outer rod.

[0013] Furthermore, the locking mechanism includes a pad, a second threaded rod, and a clamping block. The pad is disposed on the top of the outer rod, the second threaded rod passes through the pad, and a movable handle is hinged to the top of the second threaded rod. A second threaded hole is provided at the center of the top of the clamping block, and the clamping block is movably disposed inside the outer rod. The second threaded rod passes through one of the anchor holes on the outer rod into the groove of the inner rod and is threadedly connected to the second threaded hole.

[0014] Furthermore, the edge of the slide groove is provided with a downwardly extending recess, and the top of the clamping block is provided with a guide groove that engages with the recess.

[0015] The beneficial effects of this utility model are as follows: The length of the telescopic stop bar is adjusted by sliding the inner and outer rods, thus adapting to elevator shafts of different widths. The first and second mating parts at both ends of the main fixing rod overlap through the opening of the semi-threaded rod, and the locking ring is screwed tightly to the boss limit position, enabling rapid splicing and extension of multiple rods. The lower fixing frame of the fixing component drives the clamping plate to clamp the outer edge of the elevator shaft through the rotation of the first threaded rod of the clamping rod, forming a stable support. Compared with traditional integral protective structures, this protective structure can be disassembled and reassembled, reducing transportation costs and supporting repeated use; the dynamic adjustment mechanism adapts to shafts of different sizes, avoiding waste from on-site cutting; the rapid splicing structure reduces installation time and improves construction efficiency; the clamping and fixing method eliminates the need for welding, reducing usage costs. This component integrates telescopic width adjustment, modular splicing, and mechanical clamping technologies to achieve a balance between the universality, economy, and ease of construction of safety protection, effectively solving the technical pain points of traditional protective structures such as fixed dimensions, non-reusability, and complex installation.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, this utility model provides an assembled elevator shaft protective steel component, including two parallel main fixing rods 10, with a plurality of telescopic baffles 20 linearly and equally spaced between the main fixing rods 10. Each main fixing rod 10 includes a first docking part 11 and a second docking part 12 at its two ends. The first docking part 11 and the second docking part 12 on any two main fixing rods 10 can be detachably connected together. A fixing member 13 is provided on the outer side of the main fixing rod 10 away from the telescopic baffles 20. Each telescopic baffle 20 includes an outer rod 22 and inner rods 21 at its two ends. A locking mechanism 23 is provided at the intersection of each inner rod 21 and the outer rod 22. The other end of the inner rod 21 is connected to the main fixing rod 10. The overall width of the protective component can be dynamically adjusted through the design of the telescopic baffles 20. At the same time, the docking parts at both ends can be quickly assembled based on the length of the elevator shaft, thereby increasing the applicability to elevator shafts of different sizes.

[0025] In this embodiment, the first docking part 11 includes a first semi-threaded rod 1101 disposed at the center of the end of the main fixing rod 10, with a first opening at its end. A locking ring 1102 is movably disposed on the first docking part 11. The second docking part 12 includes a second semi-threaded rod 1201 disposed at the center of the other end of the main fixing rod 10, with a second opening at its end, the opening direction of which is opposite to that of the first opening. The diameters of the first semi-threaded rod 1101 and the second semi-threaded rod 1201 are the same. After the two openings on any two main fixing rods 10 overlap, the locking ring 1102 can be threaded to the middle of the two. A boss 1202 is disposed on the outer side of the second semi-threaded rod 1201 near the main fixing rod 10. When the locking ring 1102 is threaded to the center of the two semi-threaded rods, the locking ring 1102 abuts against the boss 1202. The boss 1202 limits the movement position of the locking ring 1102, ensuring the stability of the connection between the two semi-threaded rods.

[0026] In this embodiment, the fixing member 13 includes a lower fixing frame 1301 disposed on the outer side of the main fixing rod 10 away from the telescopic stop bar 20. A first threaded hole 13011 is provided on the outer side of the lower fixing frame 1301 near the bottom. A clamping rod 1302 is movably disposed in the first threaded hole 13011.

[0027] The clamping rod 1302 includes a first threaded rod 13021 threaded in the first threaded hole 13011, a clamping plate 13023 at one end of the threaded rod near the telescopic stop bar 20, and a rotating handle 13022 at the other end.

[0028] In use, adjust the length of the telescopic stop bar 20 so that the two main fixing rods 10 are extended to a suitable width of the elevator shaft, and the outer edges of the two main fixing rods 10 are level with the outer edge of the elevator shaft opening. At this time, rotate the clamping rod 1302 so that the clamping plate 13023 is clamped to the outer edge of the elevator shaft, thus fixing the protective steel component.

[0029] In a preferred embodiment, the clamping plate 13023 is provided with an anti-slip layer to increase the stability of the clamping layer of the fastener 13. The anti-slip layer is an anti-slip texture or a rubber pad layer.

[0030] In this embodiment, the top of the inner rod 21 is provided with a sliding groove 2101, and the outer top of the outer rod 22 is provided with anchor holes arranged linearly. The locking mechanism 23 includes a pad 2301, a second threaded rod 2302, and a clamping block 2304. The pad 2301 is disposed on the top of the outer rod 22. The second threaded rod 2302 is disposed through the pad 2301. The top of the second threaded rod 2302 is hinged with a movable handle 2303. The clamping block 2304 is provided with a second threaded hole 23042 at the top center. The clamping block 2304 is movably disposed inside the outer rod 22. The second threaded rod 2302 passes through one of the anchor holes on the outer rod 22 into the sliding groove 2101 of the inner rod 21 and is threadedly connected to the second threaded hole 23042. That is, by rotating the second threaded rod 2302, the position of the clamping block 2304 on the threaded rod can be adjusted to achieve the tightness and looseness of the inner rod 21 and the outer rod 22, thereby realizing the length adjustment function of the telescopic stop bar 20.

[0031] As a preferred embodiment, the edge of the slide groove 2101 is provided with a downwardly extending recess, and the top of the clamping block 2304 is provided with a guide groove 23041 that engages with the recess. This structure ensures the stability of the clamping block 2304 when sliding, and at the same time provides better connection contact when clamping and fixing.

[0032] Specifically, the working principle of this assembled elevator shaft protective steel component is as follows: During use, the length of the telescopic stop bar 20 is first adjusted according to the width of the elevator shaft. By rotating the locking mechanism 23 and releasing the clamping block 2304, the inner rods 21 at both ends of the telescopic outer rod 22 can be adapted to the width. The first docking part 11 and the second docking part 12 at both ends of the main fixing rod 10 overlap through the openings on the two semi-threaded rods. The locking ring 1102 moves threadedly to the center of the two semi-threaded rods, abutting against the boss 1202 to form a stable connection, achieving multi-rod splicing extension. The fixing member 13, by rotating the first threaded rod 13021 of the clamping rod 1302, clamps the clamping plate 13023 against the outer edge of the elevator shaft, ensuring the component is fixed. The overall structure achieves adaptable protection for elevator shafts of different sizes through a triple mechanism of dynamic width adjustment of the telescopic stop bar 20, rapid splicing of the docking parts, and stable clamping by the fixing member 13. It also supports disassembly and reuse, improving construction safety and economy.

[0033] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
