Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and specifically relates to an elevator with a function of preventing a cage from sinking. Background Art

[0002] An elevator is a device that can vertically transport materials or personnel. An elevator generally includes a frame, guide rails, a cage, and a hoist. The guide rails and the hoist are installed on the frame. The cage is connected to the steel cable of the hoist. At the same time, the cage is also connected to the guide rails through sliders, and the hoist is used to drive the cage to lift and lower to achieve the transportation of materials or personnel.

[0003] Generally, a freight elevator runs the cage to the loading port position to pick up goods. When a very heavy goods is placed in the cage, the goods will exert a large force on the bottom of the cage, which is likely to cause the cage to sink (the sinking phenomenon means that when the goods are placed in the cage, the overall position of the cage is lower than the initial docking position), which is not conducive to the safety of goods transportation. For the cage sinking phenomenon, the following two methods are mostly used in the industry to solve it: Method 1: Use a rack and pinion as the lifting transmission device; Method 2: A general chain freight elevator uses a high-power motor or a hollow shaft motor. In the first method, the transmission device needs to be equipped with four motors, which has the problems of high cost and motor out-of-synchronization; the second method has the problems of high equipment cost and limited lifting speed. Summary of the Utility Model

[0004] In order to overcome the defects in the prior art, the embodiment of the utility model provides an elevator with a function of preventing a cage from sinking, which solves the problem of cage sinking when loading goods on the elevator at a lower cost, improves the docking accuracy of the cage at the loading port, and reduces the loading risk caused by cage sinking.

[0030] In addition, the terms "first", "second", etc. are only used for distinction in description and have no special meaning.

[0031] Combined with Figures 1 to 3 As shown, the elevator with the function of preventing the suspension cage from sinking in this embodiment mainly includes: a frame 1, a lifting mechanism (not shown), a suspension cage 2, a first power source 31, and at least one first blocking rod 41. Of course, it also includes an electric control system for controlling the automated operation of the lifting mechanism and an anti-falling system electrically connected to the electric control system. The electric control system and the anti-falling system are both prior arts.

[0032] Specifically, the frame 1 of this embodiment serves as the main body of the elevator and is mainly used for installing and supporting the above-mentioned other components. The frame 1 is provided with a loading opening, and a first support rod 11 is provided near the loading opening. Preferably, the first support rod 11 is arranged at the bottom of the loading opening. The lifting mechanism is installed on the frame 1 and is used to drive the suspension cage 2 to lift and lower in the vertical direction. The first power source 31 is connected to the suspension cage 2, and at least one first blocking rod 41 is connected to the output shaft of the first power source 31. The first blocking rod 41 is used to be driven by the first power source 31 to extend and connect with the first support rod 11 after the suspension cage 2 runs to the position of the loading opening, so as to limit the suspension cage 2 in the vertical direction, and further prevent the suspension cage 2 from sinking during the process of placing goods.

[0033] As Figure 1As shown in the figure, the output shaft of the first power source 31 in this embodiment is connected to the first blocking rod 41 through the first connecting plate 51. Specifically, the first connecting plate 51 is vertically connected to the output shaft of the first power source 31. Preferably, a first blocking rod 41 is connected to each of the two ends of the first connecting plate 51. With the above solution, the two first blocking rods 41 are lapped on the first support rod 11, which can improve the limit stability and reliability of the cage 2 and enhance the ability to prevent the cage 2 from sinking.

[0034] Combined with Figure 1 、 Figure 2 and Figure 4 As shown in the figure, for the hoist in this embodiment, a second support rod 12 is further provided near the loading opening thereof, and the second support rod 12 and the first support rod 11 are arranged oppositely. The hoist further includes a second power source 32 connected to the cage 2, and a second blocking rod 42 for connecting to the second support rod 12 is connected to the output shaft of the second power source 32. Further, the output shaft of the second power source 32 can also be connected to the second blocking rod 42 through the second connecting plate 52, and a second blocking rod 42 is provided at each of the two ends of the second connecting plate 52. With the above solution, the reliability of preventing the cage 2 from sinking can be further improved.

[0035] As Figure 2 shown in the figure, both the first power source 31 and the second power source 32 are installed at the bottom of the cage 2. As Figure 3 and Figure 4 shown in the figure, when the output shaft of the first power source 31 extends out, the first blocking rod 41 is lapped on the first support rod 11, and when the output shaft of the second power source 32 extends out, the second blocking rod 42 is lapped on the second support rod 12.

[0036] Specifically, the first power source 31 and the second power source 32 can be telescopic electric cylinders.

[0037] As Figure 2 shown in the figure, the hoist in this embodiment can further include a plurality of anti-falling rods 13, and the plurality of anti-falling rods 13 are spaced apart along the vertical direction of the frame 1. Specifically, the distance between two adjacent anti-falling rods 13 above and below is between 3 and 5 m. The telescopic electric cylinders serving as the first power source 31 and the second power source 32 are both electrically connected to the electric control system and the anti-falling system of the hoist. When the anti-falling system receives the signal that the cage 2 stalls, the output shafts of the first power source 31 and the second power source 32 extend out so that the first blocking rod 41 and the second blocking rod 42 can be lapped on the nearest anti-falling rod 13. In this way, the safety protection level of the hoist is improved.

[0038] In summary, the working process of the hoist with the function of preventing the suspension cage from sinking in this embodiment is as follows: during the up and down operation of the suspension cage 2, the output shafts of the first power source 31 and the second power source 32 retract to avoid the first blocking rod 41 and the second blocking rod 42 affecting the lifting and lowering of the suspension cage 2. When the suspension cage 2 runs to the loading opening, the output shafts of the first power source 31 and the second power source 32 extend, and the first blocking rod 41 and the second blocking rod 42 respectively lap on the first support rod 11 and the second support rod 12 to support the bottom of the suspension cage 2 and prevent the suspension cage 2 from sinking. After the loading is completed, the output shafts of the first power source 31 and the second power source 32 retract to ensure the smooth lifting and lowering of the suspension cage 2.

[0039] Specific embodiments are applied in the present invention to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
