Description

Technical Field

[0001] The present invention relates to the technical field of construction elevator structures, and in particular to a construction elevator access passage protective structure. Background Art

[0002] Construction elevators are typically installed on the exterior walls of buildings, lifting workers to a specified height to allow them to enter the building for work. However, there's a certain gap between the construction elevator and the building, creating a safety hazard for workers entering the building from the elevator. Therefore, a protective passageway is required to ensure the safety of workers as they travel from the construction elevator to the interior of the building. Some solutions involve installing steps directly between the construction elevator and the building, allowing workers to walk directly from the steps into the building. However, the step connection in this solution is not stable and reliable, and is prone to shaking and slipping, posing a significant safety hazard.

[0003] Some other solutions involve installing a separate manual access route at the building's access point, which interfaces with a construction elevator to facilitate access for construction workers. However, this solution requires the construction of a separate manual access route, which increases the number of construction steps and the difficulty of construction, hindering overall construction efficiency.

[0004] Clearly, the current docking scheme between construction elevators and buildings still has issues that need to be addressed. Optimization is needed to improve the integration of construction elevators with the building structure, facilitate personnel passage, and ensure safety and reliability. Therefore, a more reasonable technical solution is needed to address the technical issues existing in the existing technology. Summary of the Invention

[0005] In order to overcome at least one of the defects mentioned above, the present invention proposes a construction elevator access passage protection structure, which aims to set the construction elevator's protection structure to be movable, so that an artificial passage is automatically formed when the protection door is opened, and the structure can automatically fold to form a protection structure when the protection door is closed. It is not only flexible and simple to use and easy to operate, but also safer and more reliable.

[0006] In order to achieve the above objectives, the protective structure disclosed in the present invention can adopt the following technical solutions: A construction elevator access passage protection structure includes a cover plate that opens and closes relative to the construction elevator, wherein the cover plate forms a walking protection structure when in the open position and forms a lower protection structure of the construction elevator when in the closed position; a tension rope is connected to the cover plate and extends to the protection plate; the protection plate is slidably arranged on the construction elevator, and when the upper guard plate slides upward to open the construction elevator door, the tension rope is loosened and the cover plate is flipped to the open position; when the protection plate slides downward to close the construction elevator door, the tension rope is tightened and the cover plate is flipped to the closed position.

[0007] The protective structure disclosed above, through the cover plate and protective plate set at the construction elevator, can realize the automatic falling of the cover plate while opening the protective plate after being linked by a tension rope, and the automatic rotation and opening of the cover plate while closing the protective plate. This can improve the safety of workers entering the building from the construction elevator, and the operation is simpler and more flexible, which is convenient for improving construction efficiency.

[0008] Furthermore, the tension rope, in conjunction with the protective plate, enables the lower cover plate to be flipped open and closed. The tension rope can be arranged in a variety of ways, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: a pulley structure is provided on the upper portion of the construction elevator. The tension rope corresponds to the pulley structure one-to-one, and the tension rope is wound around the pulley structure and then connected to the protective plate. When adopting this solution, the tension rope can be a steel wire rope, and the pulley structure uses a fixed pulley. The fixed pulley is used to change the force transmission direction of the steel wire rope, facilitating the synchronous flipping of the cover plate by the raising and lowering of the protective plate.

[0009] Furthermore, after the protective plate is raised or lowered, it needs to be locked to maintain its structural stability. Specifically, the protective plate is provided with a latch structure, and the construction elevator is provided with at least two latch seats that correspond to the latch structure. When the protective plate slides up to open the construction elevator door, the latch structure corresponds to the upper latch seat, and when the protective plate slides down to close the construction elevator door, the latch structure corresponds to the lower latch seat. When adopting this solution, when the latch structure engages at the upper latch seat, the protective plate and cover plate are kept in the open position, and when the latch structure engages at the lower latch seat, the protective plate and cover plate are kept in the closed position.

[0010] Furthermore, the latch structure can be constructed in a variety of forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the latch structure includes a latch barrel, an elastic member disposed within the latch barrel, a latch pin disposed within the latch barrel and subjected to an elastic force exerted by the elastic member. The latch pin protrudes from the latch barrel and forms a bent structure that mates with the latch seat. When adopting this solution, the latch pin can extend and retract along the latch barrel, and can also rotate along the latch barrel. During the extension and rotation, the latch pin engages with the latch barrel, thereby locking the protective plate with the latch pin.

[0011] Furthermore, the latch holder, which is used to restrain the latch, can adopt a variety of solutions, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the latch holder includes a base body with a latch formed therein that corresponds to the latch. When the latch enters the latch, the latch prevents the latch and the protective plate from further vertical movement. When adopting this solution, the latch holder can be welded to the construction elevator or fixed to the construction elevator via connecting fasteners.

[0012] Furthermore, the construction elevator and the protective plate can adopt various forms of coordination, and the structure is not limited to a single one. Here, we optimize and propose one feasible option: a slideway structure is formed between the construction elevator and the protective plate, and the protective plate moves vertically along the slideway. In this solution, the slideway structure includes a slide groove provided on the construction elevator, and a sliding block or sliding bar provided on the protective plate to correspond with the slide groove; or the slideway structure includes a slider or sliding bar provided on the construction elevator, and a corresponding slide groove provided on the protective plate.

[0013] Furthermore, after the cover is deflected and lowered, protective structures are formed on both sides to protect workers from passing through. The protective structure can adopt a variety of schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the cover is connected to a protective link, which includes a first link and a second link that are hinged to each other. The first link is hinged to the cover, and the second link is hinged to the construction elevator. When the cover is flipped to the open position, the first link and the second link form a side barrier structure. When the cover is flipped to the closed position, the first link and the second link are folded together. When adopting the above scheme, when the first link and the second link form the side barrier structure, the first link and the second link form a 90° angle.

[0014] Furthermore, when connecting the first or second connecting base, a connecting structure is provided for each connection. Here, an optimization is proposed, and a feasible option is proposed: the cover plate is provided with a first hinged base for connecting and cooperating with the first connecting rod, and the construction elevator is provided with a second hinged base for connecting and cooperating with the second connecting rod. When adopting this solution, the first and second hinged bases can be fixed by welding or by connecting fasteners.

[0015] Furthermore, to facilitate the operation of the protective plate, an optimization is proposed here, in which a feasible option is provided: the protective plate is provided with an operation hole structure. When adopting the above solution, the operation hole structure includes two through holes, and the protective plate can be slid upward or downward by pulling the operation holes.

[0016] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in the present invention include: By setting up a linkage between the cover plate and the protective plate, the deflection of the cover plate is achieved while operating the protective plate, providing a stable and reliable construction channel for workers to enter the building from the construction elevator, which is conducive to improving the overall construction efficiency and eliminating safety hazards.

[0025] This embodiment will be further explained below with reference to the accompanying drawings and specific examples.

[0026] In view of the fact that the construction elevator protective structure in the prior art has poor safety performance, is not convenient for specific operation, and is not conducive to improving construction efficiency, the following embodiments are optimized and overcome the defects in the prior art.

[0027] Example like Figures 1 to 6As shown, this embodiment discloses a construction elevator access passage protection structure, including a cover plate 2 that opens and closes relative to the construction elevator 1, the cover plate 2 forms a walking protection structure when in the open position, and forms a lower protection structure of the construction elevator 1 when in the closed position; a tension rope 4 is connected to the cover plate 2, and the tension rope 4 extends to the protection plate 5; the protection plate 5 is slidably arranged on the construction elevator 1, when the upper guard plate slides upward to open the construction elevator door, the tension rope 4 is loosened and the cover plate 2 is flipped to the open position, and when the protection plate 5 slides downward to close the construction elevator door, the tension rope 4 is tightened and the cover plate 2 is flipped to the closed position.

[0028] The protective structure disclosed in this embodiment, through the cover plate 2 and the protective plate 5 set at the construction elevator 1, can realize the automatic falling of the cover plate 2 while opening the protective plate 5 after being linked by the tension rope 4, and can realize the automatic rotation and opening of the cover plate 2 while closing the protective plate 5. This can improve the safety of workers entering the building from the construction elevator 1, and the operation is simpler and more flexible, which is convenient for improving construction efficiency.

[0029] The tension rope 4 cooperates with the protective plate 5 to realize the flip opening and flip closing of the lower cover plate 2. The setting method of the tension rope 4 can adopt a variety of schemes, and its structure is not limited to a single one. This embodiment optimizes and adopts one of the feasible options: the upper part of the construction elevator 1 is provided with a pulley structure 6, and the tension rope 4 corresponds to the pulley structure 6 one by one. The tension rope 4 is wound around the pulley structure 6 and then connected to the protective plate 5. When adopting the above scheme, the tension rope 4 can be a steel wire rope, and the pulley structure 6 can be a fixed pulley. The fixed pulley is used to change the force transmission direction of the steel wire rope, so that the cover plate 2 can be flipped synchronously with the raising and lowering of the protective plate 5.

[0030] After the protective plate 5 is raised or lowered, it needs to be locked to maintain its structural stability. Specifically, the protective plate 5 is provided with a latch structure 9, and the construction elevator 1 is provided with at least two latch seats 10 that correspond to the latch structure 9. When the protective plate 5 slides up and opens the construction elevator door, the latch structure 9 corresponds to the upper latch seat 10. When the protective plate 5 slides down and closes the construction elevator door, the latch structure 9 corresponds to the lower latch seat 10. When adopting the above solution, when the latch structure 9 is engaged at the upper latch seat 10, the protective plate 5 and the cover plate 2 are kept in the open position. When the latch structure 9 is engaged at the lower latch seat 10, the protective plate 5 and the cover plate 2 are kept in the closed position.

[0031] The latch structure 9 can be constructed in various forms, and its structure is not limited to a single form. This embodiment optimizes and adopts one feasible option: the latch structure 9 includes a latch barrel 901, an elastic member 902 is disposed within the latch barrel 901, and a latch pin 903 is disposed at the latch barrel 901 and is subjected to an elastic force exerted by the elastic member 902. The latch pin 903 protrudes from the latch barrel 901 and forms a bent structure 904 that corresponds to the latch seat 10. When adopting this solution, the latch pin 903 can extend and retract along the latch barrel 901, and can also rotate along the latch barrel 901. During the extension and rotation, the latch pin 903 can be engaged with the latch barrel 901, thereby achieving the locking of the latch pin 903 on the protective plate 5.

[0032] Preferably, the elastic member 902 may be a spring.

[0033] The latch holder 10 is used to engage and restrain the latch 903. Various solutions are possible, and its structure is not strictly limited. This embodiment optimizes and adopts one feasible option: the latch holder 10 includes a base having a notch formed thereon that engages with the latch 903. When the latch 903 engages with the notch, the notch prevents the latch 903 and the protective plate 5 from further vertical movement. When this solution is adopted, the latch holder 10 can be welded to the construction elevator 1 or secured to the construction elevator 1 via fasteners.

[0034] The structure of the construction elevator 1 and the protective plate 5 can be coordinated in various ways, and is not strictly limited to a single structure. This embodiment optimizes and adopts one feasible option: a slideway structure is formed between the construction elevator 1 and the protective plate 5, along which the protective plate 5 moves vertically. In this embodiment, the slideway structure includes a slideway provided on the construction elevator 1, and a sliding block or sliding bar provided on the protective plate 5 that cooperates with the slideway; alternatively, the slideway structure includes a slider or sliding bar provided on the construction elevator 1, and a corresponding slideway provided on the protective plate 5.

[0035] After the cover plate 2 is deflected and lowered, protective structures are formed on both sides thereof to protect workers from passing through. The protective structure can adopt a variety of schemes, and its structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the cover plate 2 is connected to the protective link 3, and the protective link 3 includes a first link 301 and a second link 302 that are hinged to each other. The first link 301 is hinged to the cover plate 2, and the second link 302 is hinged to the construction elevator 1; when the cover plate 2 is flipped to the open position, the first link 301 and the second link 302 form a side barrier structure. When the cover plate 2 is flipped to the closed position, the first link 301 and the second link 302 are folded together. When the above scheme is adopted, when the first link 301 and the second link 302 form the side barrier structure, the first link 301 and the second link 302 form a 90° angle.

[0036] When connecting the first or second connection base, a connecting structure is provided for each connection. This embodiment optimizes and adopts one feasible option: the cover plate 2 is provided with a first hinged seat 8 for connecting and cooperating with the first connecting rod 301, and the construction elevator 1 is provided with a second hinged seat 7 for connecting and cooperating with the second connecting rod 302. When adopting this solution, the first hinged seat 8 and the second hinged seat 7 can be fixed by welding or by connecting fasteners.

[0037] To facilitate the operation of the protective plate 5, this embodiment is optimized and adopts one of the feasible options: the protective plate 5 is provided with an operation hole structure 501. When adopting the above solution, the operation hole structure 501 includes two through holes, and the protective plate 5 can be slid upward or downward by pulling the operation holes.

[0038] The above are the implementation methods listed in this embodiment, but this embodiment is not limited to the above optional implementation methods. Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can derive other various implementation methods based on the inspiration of this embodiment. The above specific implementation methods should not be understood as limiting the scope of protection of this embodiment. The scope of protection of this embodiment should be based on the definition in the claims.
