[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] Example: Figures 1-8 As shown, an elevator shaft support frame includes a support frame body 1, which is the main part of the passageway. It serves two purposes: firstly, connecting the shaft to the building; and secondly, acting as a load-bearing structure for installing passageway panels, window frames, windows, etc. Figure 1 The middle section shows the main aisle panel 0, which is the main body of the aisle panel. The glass window frame and glass window are not shown in the figure.
[0029] The elevator shaft support frame in this embodiment also includes a drainage device 2, a water-blocking structure 3, and a triggering mechanism 4.
[0030] The drainage device 2 includes a drainage beam 20, which is mounted on the support frame 1 and spans the support frame 1. A water trough 21 is provided on the top of the drainage beam 20, and drainage outlets 22 connected to the water trough 21 are provided on both sides of the drainage beam 20. A passage cover 23 is provided at the inlet of the water trough 21. The passage cover 23 forms part of the passage slab required for the floor to reach the elevator. A water inlet 24 is provided on the passage cover 23, and the length of the water inlet 24 is as long as possible.
[0031] The water blocking structure 3 comprises a water blocking crossbeam 31 and a water blocking plate 32. The water blocking crossbeam 31 is arranged on the support frame body 1 and crosses the support frame body 1. The water blocking crossbeam 31 comprises a passageway plate component 311 and a bottom plate component 312 arranged below the passageway plate component 311. The passageway plate component 311 is also a part of the passageway plate required for the floor to access the elevator. The bottom plate component 312 is connected with the support frame body 1. The passageway plate component 311 is connected with the bottom plate component 312 through a connecting plate 310. The connecting plate 310 is used for installing a hall door sill. A baffle limiting groove 313 is formed on the top surface of the passageway plate component 311. The water blocking plate 32 is assembled in the baffle limiting groove 313 and extends downward out of the baffle limiting groove 313. The bottom of the water blocking plate 32 is provided with a compression spring I 33 connected with the bottom plate component 312. The side of the water blocking plate 32 facing the drainage crossbeam 20 is provided with a lock hole 321. A lock piece 34 is slidingly arranged in the water groove 21. One end of the lock piece 34 penetrates through the drainage crossbeam 20 and extends into the lock hole 321. The drainage crossbeam 20 is provided with a through hole 25 through which the lock piece 34 penetrates. The other end of the lock piece 34 is connected with a compression spring II 35. The other end of the compression spring II 35 is connected with the groove wall of the water groove 21.
[0032] The triggering mechanism 4 comprises a floating ball 41, a pull rope 42 connecting the lock piece 34 and the floating ball 41, and a vertical limiting cylinder 43 arranged in the water groove 21 and used for limiting the floating ball 41. The floating ball 41 is arranged below the drainage port 22 to ensure that the floating ball 41 can float upward. The vertical limiting cylinder 43 is arranged laterally to the lock piece 34 and above the compression spring II 35, so that the floating ball 41 is arranged laterally above the lock piece 34, which ensures that the floating ball 41 can pull the lock piece 34 laterally when floating upward, and meanwhile, the floating ball 41 does not interfere with the compression spring II 35 and other components.
[0033] Under normal circumstances, the lock piece 34 is inserted into the lock hole 321 under the elastic force of the compression spring II 35. The water blocking plate 32 is limited and kept in a state that the top is flush with the upper surface of the passageway plate component 311. At the same time, the pull rope 42 is in a tensioned state.
[0034] When the rain flows to the shaft, on the one hand, the rain enters the water tank 21 from the water inlet 24, and on the other hand, the floating ball 41 in the water tank 21 gradually floats up due to the accumulation of rain, the floating ball 41 overcomes the elastic force of the compression spring two 35 and pulls the lock piece 34 to move laterally during the floating process, when the amount of water entering the water tank 21 reaches a certain amount, the floating ball 41 makes the lock piece 34 exit the lock hole 321, at this time, the water baffle 32 is pulled up by the elastic force of the compression spring one 33, the water baffle 32 blocks the rain, greatly prevents the rain from flowing into the shaft, and improves the safety performance of the elevator. When the water level in the water tank 21 reaches the drain 22, the rain in the water tank 21 is discharged from the drain 22.
[0035] In the embodiment, the water tank 21 is provided with an overhead plate 26, the overhead plate 26 forms a mounting space with the bottom of the water tank 21, the lock piece 34 is slidingly installed on the overhead plate 26 and suspended in the mounting space, specifically, the bottom of the overhead plate 26 is provided with a sliding rail part 261, and the lock piece 34 is provided with a sliding block part 341 matched with the sliding rail part 261. The purpose of this is that after the elevator is used for a long time, the bottom of the water tank 21 is likely to accumulate a certain amount of silt, and the lock piece 34 is suspended, which is beneficial to reduce the influence of silt on the movement of the lock piece 34.
[0036] In the embodiment, the bottom surface of the vertical limiting cylinder 43 is fixedly connected to the overhead plate 26, so that the bottom cylinder opening of the vertical limiting cylinder 43 is covered by the overhead plate 26, preventing the floating ball 41 from falling from the bottom cylinder opening of the vertical limiting cylinder 43, and the vertical limiting cylinder 43 does not need to be provided with another structure to achieve the effect of preventing the floating ball 41 from falling, and the structure of the vertical limiting cylinder 43 can be simplified.
[0037] In the embodiment, the cylinder wall of the vertical limiting cylinder 43 is provided with a water inlet opening 431, the top of the water inlet opening 431 is not lower than the drain 22, which improves the performance of the rain entering the vertical limiting cylinder 43 and ensures the reliability of the buoyancy.
[0038] In the embodiment, the height of the through hole 25 is higher than the height of the drain 22, which ensures that the rain in the water tank 21 can only be discharged from the drain 22, and cannot be discharged from the through hole 25.
[0039] In the embodiment, the surface of the compression spring two 35 is provided with an anti-rust layer, which can be but is not limited to a paint layer, and the performance of the compression spring two 35 is ensured by providing the anti-rust layer.
[0040] In the embodiment, the aisle cover plate 23 is detachably connected at the inlet of the water tank 21. When the water baffle 32 needs to be reset, the aisle cover plate 23 is first opened, the residual rainwater in the water tank 21 is pumped out, then force is applied to the lock piece 34 to make the lock piece 34 retreat into the water tank 21, and the water baffle 32 is pressed downwardly, then the lock piece 34 is released, the lock piece 34 is abutted against the water baffle 32 under the action of the second retracting spring 35, the water baffle 32 is continuously pressed downwardly until the lock piece 34 is aligned with the lock hole 321 and is inserted into the lock hole 321. In addition, after long time use, the water tank 21 is likely to have problems such as excessive silt, therefore, the aisle cover plate 23 can also be opened to clean.
[0041] The above embodiment only describes the preferred embodiment of the present application, and does not limit the concept and scope of the present application. Various modifications and improvements to the technical solution of the present application made by those skilled in the art without departing from the design concept of the present application shall fall within the protection scope of the present application, and the technical content of the present application claimed for protection has been entirely recorded in the claims.
