Description

Technical Field

[0001] This invention relates to elevator corridor bridges, and more specifically to a flexible, quick-installation elevator corridor bridge. Background Technology

[0002] In the prior art, an external elevator system includes: an external elevator shaft and a corridor bridge. The external elevator shaft provides space for the elevator car to move up and down. The external elevator shaft is fixed to the first end of the corridor bridge, and the second end of the corridor bridge connects to the building. There are multiple corridor bridges, and the second end of the corridor bridge connects to each floor of the building.

[0003] Since the second end of the corridor bridge is fixed to the building, and the additional elevator shaft is newly added next to the building, the newly installed additional elevator shaft is prone to sinking due to reasons such as land subsidence. This will pull the building tilt through the corridor bridge, resulting in a lower building safety factor. Summary of the Invention

[0004] The present invention provides a flexible connection quick-installation elevator bridge to solve the problem in the prior art where the building is fixed at the second end of the bridge, causing the elevator shaft to sink and the bridge to pull the building to tilt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses a flexible connection type quick-installation elevator corridor bridge, comprising: a corridor bridge structure, a shaft-side flexible connection structure, and a building-side adaptive hinge structure. The first end of the corridor bridge structure is connected to an external elevator shaft through the shaft-side flexible connection structure, and the first end of the corridor bridge structure can move relative to the external elevator shaft. The second end of the corridor bridge structure is connected to the building through the building-side adaptive hinge structure, and the second end of the corridor bridge structure can move relative to the building.

[0006] Preferably, the bridge structure is supported by the ground.

[0007] Preferably, the shaft-side flexible connection structure includes: a first linearly movable connection structure, which has a first mounting part and a first connecting part. The first mounting part is installed on the external elevator shaft, and the first connecting part is installed at the first end of the corridor structure. The first connecting part can move vertically relative to the first mounting part. The direction parallel to the pedestrian direction on the corridor structure is the corridor guiding direction, and the first connecting part can also move relative to the first mounting part in the corridor guiding direction. The first end of the corridor structure is fixed to the first end of a movable step, which can move relative to the external elevator shaft in the corridor guiding direction. The second end of the movable step is supported by the external elevator shaft.

[0008] Preferably, the building-side adaptive hinge structure includes: a second linear moving connection structure, which is provided with a second mounting part and a second connecting part. The second mounting part is installed on the building, and the second connecting part can be installed at the second end of the corridor structure. The second connecting part can move vertically relative to the second mounting part, and the second connecting part can also move in the corridor guiding direction relative to the second mounting part. A movable step is installed between the second end of the corridor structure and the building floor.

[0009] Preferably, the building-side adaptive hinge structure further includes: a universal hinge structure, wherein the universal hinge structure is provided with a first mounting end and a second mounting end, the first mounting end is connected to a second connecting part, the second mounting end is installed on the second end of the corridor bridge structure, and the second mounting end can rotate universally relative to the second mounting end.

[0010] Preferably, the first end of the movable step is hinged to a hinge seat, which is installed at a floor of the building, and the second end of the movable step can be supported by the corridor structure.

[0011] Preferably, the walkway structure is equipped with a rotatable support rod that supports the second end of the movable footboard.

[0012] Preferably, the bridge structure includes a support frame and several layers of bridge body, with the support frame standing on the ground and at least two layers of bridge body installed on the support frame.

[0013] Compared to existing technologies, this invention offers the following advantages: First, by connecting the first end of the corridor bridge structure to the external elevator shaft via a flexible connection structure on the shaft side, the possibility of the external elevator shaft causing the corridor bridge structure to move is reduced. Then, by connecting the second end of the corridor bridge structure to the building via a building-side adaptive hinge structure, the possibility of the corridor bridge structure pulling the building to move is further reduced. The combined use of the flexible connection structure on the shaft side and the building-side adaptive hinge structure makes the possibility of the external elevator shaft causing the building to move almost zero, protecting the building and preventing the external elevator shaft and corridor bridge structure from interfering with the building's stability.

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 5 As shown, the present invention discloses a flexible connection type quick-installation elevator corridor bridge, including: a corridor bridge structure 1, a shaft-side flexible connection structure 2, and a building-side adaptive hinge structure 3. The first end of the corridor bridge structure 1 is connected to an external elevator shaft through the shaft-side flexible connection structure 2, and the first end of the corridor bridge structure 1 can move relative to the external elevator shaft. The second end of the corridor bridge structure 1 is connected to the building through the building-side adaptive hinge structure 3, and the second end of the corridor bridge structure 1 can move relative to the building.

[0023] In order to provide support for the corridor bridge structure 1 and reduce the burden on the building and the external elevator shaft, the corridor bridge structure 1 is supported by the ground.

[0024] Although the corridor bridge structure 1 has its own stability after being supported by the ground, it requires even greater stability to ensure that there are no gaps between it and the external elevator shaft, and also to ensure that there are no gaps between it and the building, thus guaranteeing the safety of people walking on it. Therefore, this application sets up a flexible connection structure 2 on the shaft side, which allows the corridor bridge structure 1 to be slightly pulled by the external elevator shaft to a certain extent, ensuring that it can adapt to changes in the external elevator shaft and that there is always no gap between the first end of the corridor bridge structure 1 and the external elevator shaft. Furthermore, an adaptive hinged structure 3 on the building side is designed so that although the building exerts a pulling force on the external elevator shaft, this pulling force is not large enough to maintain the stability of the corridor bridge structure 1, thus ensuring a seamless connection between the building and the second end of the corridor bridge structure 1.

[0025] The flexible connection structure 2 on the shaft side includes: a first linear moving connection structure, which has a first mounting part and a first connecting part. The first mounting part is installed on the external elevator shaft, and the first connecting part is installed at the first end of the corridor structure. The first connecting part can move vertically relative to the first mounting part. The direction parallel to the pedestrian direction on the corridor structure 1 is the corridor guiding direction, and the first connecting part can also move relative to the first mounting part in the corridor guiding direction. The first end of the corridor structure 1 is fixed to the first end of a movable step 5. The movable step 5 can move relative to the external elevator shaft in the corridor guiding direction, and the second end of the movable step 5 is supported by the external elevator shaft. The first linear moving connection structure is provided with an elastic element, which allows the external elevator shaft to elastically pull the corridor structure 1 to move, reducing the pulling force of the external elevator shaft on the corridor structure 1, so that when the external elevator shaft settles, it can pull the corridor structure 1 to a certain extent. The external elevator shaft has a landing door window, and the landing door window is provided with a support pad, which is elastic.

[0026] The building-side adaptive hinged structure 3 includes: a second linearly movable connection structure 31, which has a second mounting part and a second connecting part. The second mounting part is installed on the building, and the second connecting part can be installed at the second end of the corridor structure. The second connecting part can move vertically relative to the second mounting part and can also move in the corridor guide direction relative to the second mounting part. A movable step 4 is installed between the second end of the corridor structure 1 and the building floor. In order to adapt to the corridor structure 1 being pulled by an external elevator shaft, this application designs a second linearly movable connection structure 31, which is also provided with elastic elements. The second linearly movable connection structure 31 makes the connection between the second end of the corridor structure 1 and the building adaptable to the corridor structure 1 being pulled by an external elevator shaft.

[0027] In this application, both the first linear movable connection structure and the second linear movable connection structure 31 include: an elastic vertical movable structure 33 and an elastic horizontal movable structure 34. The first end of the elastic vertical movable structure 33 is the first mounting part of the first linear movable connection structure or the second mounting part of the second linear movable connection structure 31. The first end of the elastic vertical movable structure 33 can move elastically relative to the second end of the elastic vertical movable structure 33. The first end of the elastic horizontal movable structure 34 is mounted on the second end of the elastic vertical movable structure 33. The second end of the elastic horizontal movable structure 34 is the first connecting part of the first linear movable connection structure or the second connecting part of the second linear movable connection structure 31.

[0028] The elastic horizontally movable structure 34 includes: a first spring 341, a moving rod 342, an anti-detachment disc 343, and a guide cylinder 344. The first end of the moving rod 342 is either the first end or the second end of the elastic horizontally movable structure 34. The second end of the moving rod 342 is fixed with the anti-detachment disc 343, which is located inside the guide cylinder 344 and cannot detach from the guide cylinder 344. The first spring 341 is installed between the anti-detachment disc 343 and the guide cylinder 344. The elastic force of the first spring 341 restricts the movement of the anti-detachment disc 343 and the moving rod 342 relative to the guide cylinder 344. The end of the guide cylinder 344 away from the moving rod 342 is either the second end or one end of the elastic horizontally movable structure 34. It can be seen that the flexible horizontal movable structure 34 restricts the movement of the external elevator shaft relative to the corridor structure 1 in the corridor guiding direction, so as to make the external elevator shaft and the corridor structure 1 partially separate, and also to make the corridor structure 1 and the building not separate.

[0029] In the first linear moving connection structure, the anti-detachment disc 343 and the guide cylinder 344 have a first compensation gap, and the moving rod 342 and the guide cylinder 344 have a second compensation gap. The first compensation gap and the second compensation gap enable the corridor bridge structure 1 to adapt to slight deflection when the external elevator shaft sinks.

[0030] Optionally, the elastic vertically movable structure 33 includes: a second spring 331, a fixed seat 332, a lifting seat 333, a guide rod 334, and a nut 335. The fixed seat 332 is the first end of the elastic vertically movable structure 33. The fixed seat 332 is passed through by the guide rod 334. The guide rod 334 is threadedly connected to two nuts 335. A second spring 331 is installed between each nut 335 and the fixed seat 332. The two nuts 335 are located above and below the fixed seat 332, respectively. The guide rod 334 is fixed to the lifting seat 333. The lifting seat 333 is the second end of the elastic vertically movable structure 33.

[0031] In this application, the building-side adaptive hinge structure 3 further includes a universal hinge structure 32, which has a first mounting end and a second mounting end. The first mounting end is connected to a second connecting part, and the second mounting end is mounted on the second end of the corridor structure. The second mounting end can rotate omnidirectionally relative to the second mounting end. The universal hinge structure 32 prevents the building from deflecting with the corridor structure 1, allowing the corridor structure 1 to deflect relative to the building in multiple directions.

[0032] Optionally, the universal hinge structure 32 includes: a first hinge rod 321, a second hinge rod 322, a hinge cover 323, and a hinge ball. The first end of the first hinge rod 321 is the first mounting end of the universal hinge structure 32, and the second end of the first hinge rod 321 is fixed to the hinge cover 323. A hinge ball capable of omnidirectional rotation is installed inside the hinge cover 323. The hinge ball is fixed to the first end of the second hinge rod 322, and the second end of the second hinge rod 322 is the second mounting end of the universal hinge structure 32. This enables the first mounting end of the universal hinge structure 32 to rotate omnidirectionally relative to the second mounting end.

[0033] To accommodate the deflection of the corridor structure 1 relative to the building, the first end of the movable step 4 is hinged to a hinge seat, which is installed at the floor level of the building. The second end of the movable step 4 can be supported by the corridor structure 1. The movable step 4 effectively seals the gap between the building and the corridor structure 1, and its installation allows for the adaptation to the movement and lifting of the corridor structure 1.

[0034] To ensure that the second end of the movable pedal 4 can be supported, a rotatable support rod 10 is installed on the bridge structure 1. The support rod 10 supports the second end of the movable pedal 4. The surface of the support rod 10 is elastic so that the second end of the movable pedal 4 can be fully supported even after the bridge structure 1 is deflected.

[0035] An elastic block 13 is installed between the bridge structure 1 and the movable step 4, and the elastic block 13 seals the gap between the second end of the movable step 4 and the bridge structure.

[0036] In order to enable the bridge structure 1 to be supported by the ground, the bridge structure 1 includes: a support frame 11 and several layers of bridge body 12. The support frame 11 stands on the ground, and at least two layers of bridge body 12 are installed on the support frame 11.

[0037] Firstly, to ensure seamless connection between the first end of the corridor bridge structure 1 and the external elevator shaft, and seamless connection between the second end of the corridor bridge structure 1 and the building, while also ensuring the stability of the corridor bridge structure 1 itself and reducing the burden on the external elevator shaft and the building, the following design was implemented: "The corridor bridge structure 1 is supported by the ground. The first end of the corridor bridge structure 1 is connected to the external elevator shaft through the shaft-side flexible connection structure 2, and the second end of the corridor bridge structure 1 is connected to the building through the building-side adaptive hinge structure 3." The designed shaft-side flexible connection structure 2 can pull the corridor bridge structure 1 to a certain extent when the heavy external elevator shaft sinks, ensuring seamless connection between the first end of the corridor bridge structure 1 and the external elevator shaft. At the same time, by setting the building-side adaptive hinge structure 3, the building has the effect of stabilizing the corridor bridge structure 1, ensuring seamless connection between the building and the stable corridor bridge structure 1, and also reducing the pulling force of the corridor bridge structure 1 on the building, thus preventing the building from tilting. Then, based on the premise that the corridor structure itself is supported by the ground, a flexible connection structure 2 on the shaft side is designed, including a first linear moving connection structure. The first linear moving connection structure enables the external elevator shaft to move the corridor structure 1 through elasticity. Furthermore, in order to prevent the corridor structure 1 from deflecting with the external elevator shaft to a certain extent, a design is made that "the anti-detachment plate 343 and the guide cylinder 344 have a first compensation gap, and the moving rod 342 and the guide cylinder 344 have a second compensation gap." This is also under the premise that the corridor structure 1 is supported by the ground (if the corridor structure 1 is not supported by the ground and relies on the external elevator shaft and corridor for support, the first and second compensation gaps cannot be set because they need to be supported by the guide cylinder 344 and the moving rod 342, so the first and second compensation gaps cannot be set at all). The setting of the first and second compensation gaps can compensate for the deflection of the external elevator shaft, allowing the guide cylinder 344 on the corridor structure 1 to adapt to the moving rod 342 deflecting with the external elevator shaft. Finally, this application designs a building-side adaptive hinge structure 3 that includes both a second linear moving connection structure 31 and a universal hinge structure 32. When the corridor bridge structure 1 moves in the corridor bridge guiding direction under the pull of the first linear moving connection structure, the second linear moving connection structure 31 restricts the movement of the corridor bridge structure 1, but also allows this slight movement. Therefore, it also stabilizes the corridor bridge structure 1 under the second linear moving connection structure 31. However, by setting the first spring 341 and the second spring 331, the pulling force of the corridor bridge structure 1 on the building is reduced. On this basis, since the lighter corridor bridge structure 1 can be pulled by the external elevator shaft, the corridor bridge structure 1 will also deflect to a certain extent with the external elevator shaft. Therefore, a universal hinge structure 32 is designed between the corridor bridge structure 1 and the second linear moving connection structure 31. The universal hinge structure 32 allows the corridor bridge structure 1 to deflect relative to the building in many directions, so that the deflection of the corridor bridge structure 1 will not cause the building to deflect, thus improving the protection of the building.If the universal hinge structure 32 is set between the corridor bridge structure 1 and the building, the second linear moving connection structure 31 will affect the function of the universal hinge structure 32, and the function of the universal hinge structure 32 will basically be impossible to realize.

[0038] The movable pedal 4 and the moving pedal 5 are covered with a telescopic waterproof cover 6, which can be slightly twisted and extended.
