Description

A type of ultra-large area vibration-damping elevator car bottom Technical Field

[0001] This utility model relates to the field of elevator engineering technology, and in particular to an ultra-large area vibration-damping elevator car bottom. Background Technology

[0002] With the acceleration of urbanization, the demand for freight transportation is increasing, especially in logistics centers, large shopping malls, and industrial plants, where freight elevators have become an indispensable means of transportation. However, traditional freight elevators often encounter problems such as high vibration, high noise, and structural fatigue when subjected to high loads and frequent loading and unloading operations.

[0003] For example, Chinese utility model patent CN221759278U discloses an elevator car bottom assembly, which allows for easy disassembly and replacement of the shock-absorbing components on the inner wall of the device, thereby effectively improving the practicality of the device. However, such a structure still has the following significant drawbacks:

[0004] 1. The existing shock-absorbing components at the bottom of the elevator bridge use a spring design, which shortens the service life of the equipment and increases maintenance costs. At the same time, this design has a low utilization rate of the shaft space and also limits the elevator's adaptability to the installation environment.

[0005] 2. The existing elevator bridge has a ventilation and dust removal device at the bottom. This device does not have a self-cleaning function for the slots, so the slots are easily blocked by dust. This not only reduces ventilation efficiency and weakens dust removal effect, but also requires frequent manual cleaning, which increases maintenance costs and workload. Summary of the Invention

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

[0007] This application provides an ultra-large area vibration-damping elevator car bottom, including a car bottom plate and a car bottom frame assembly; the car bottom plate includes an upper car bottom plate and a lower car bottom plate, and a grid rib assembly is fixed between the upper car bottom plate and the lower car bottom plate. The grid rib assembly divides the space between the upper car bottom plate and the lower car bottom plate into several independent grids, and each independent grid is equipped with vibration-damping rubber.

[0008] Furthermore, the grid rib assembly includes deep ribs, wide ribs, deep edge banding and wide edge banding. Several deep ribs and wide ribs are evenly distributed on the top surface of the lower car bottom plate along its depth direction and width direction, respectively. The deep edge banding and wide edge banding are respectively fixed on the four sides of the top surface of the lower car bottom plate.

[0009] Furthermore, a certain gap is left between the deep edge banding and the wide edge banding and the corresponding edge of the top surface of the lower car floor.

[0010] Furthermore, a cleaning plate is provided on the top of the upper car floor, and the cleaning plate has holes and slots. A fixing seat is fixedly provided on the cleaning plate, and a blower fan and an exhaust fan are rotatably installed on the fixing seat.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The following description, in conjunction with the accompanying drawings, details a large-area vibration-damping elevator car bottom provided by the embodiments of this application through specific examples and application scenarios.

[0030] Example 1:

[0031] As shown in Figures 2 to 4, this application provides an ultra-large area vibration-damping elevator car bottom, including a car bottom plate 1 and a car bottom frame assembly 2; the car bottom plate 1 includes an upper car bottom plate 11 and a lower car bottom plate 12, and a grid rib assembly 3 is fixed between the upper car bottom plate 11 and the lower car bottom plate 12. The grid rib assembly 3 divides the space between the upper car bottom plate 11 and the lower car bottom plate 12 into several independent grids, and each independent grid is equipped with vibration-damping rubber 4.

[0032] Furthermore, the mesh rib assembly 3 includes a depth rib 31, a width rib 32, a depth edge seal 33, and a width edge seal 34. The top surface of the lower car bottom plate 12 has a number of depth ribs 31 and width ribs 32 distributed at equal intervals along its depth and width directions, respectively. The depth edge seal 33 and the width edge seal 34 are respectively fixed on the four sides of the top surface of the lower car bottom plate 12.

[0033] Furthermore, the deep edge banding 33 and the wide edge banding 34 are respectively separated by a certain gap from the corresponding edge of the top surface of the lower car bottom plate 12.

[0034] In this embodiment of the application, due to the above-mentioned structure, a car bottom frame assembly 2 is welded to the bottom end of the lower car bottom plate 12. The car bottom frame assembly 2 includes a frame, a secondary lower beam, a main lower beam, reinforcing ribs and a through beam. A number of deep ribs 31 and wide ribs 32 are welded at equal intervals along the depth direction and the width direction of the top of the lower car bottom plate 12. The number of them is determined by the size and length of the lower car bottom plate 12. The deep ribs 31 and wide ribs 32 divide the top of the lower car bottom plate 12 into a number of independent grids. Each independent grid is fixedly installed with vibration damping rubber 4.

[0035] The deep edge seal 33 and the wide edge seal 34 are respectively left with a certain gap between the corresponding edges of the top surface of the lower car bottom plate 12, so as to facilitate the welding of the upper car bottom plate 11 and the lower car bottom plate 12.

[0036] Example 2:

[0037] As shown in Figures 1, 5, 6 and 7, in this embodiment, in addition to the structural features of the aforementioned embodiments, a cleaning plate 5 is provided on the top of the upper car floor 11. The cleaning plate 5 has a hole groove 51 and a fixing seat 6 is fixedly provided on the cleaning plate 5. A blower fan 61 and an exhaust fan 62 are rotatably mounted on the fixing seat 6. A self-cleaning component 63 and a driving component 64 are provided inside the fixing seat 6. The driving component 64 is used to drive the blower fan 61, the exhaust fan 62 and the self-cleaning component 63 to start.

[0038] Furthermore, the drive component 64 includes a drive motor 641, a first gear 642, a second gear 643, and a third gear 644. The drive motor 641 is fixedly mounted on the fixed base 6. The output shaft of the drive motor 641 extends into the inner cavity of the fixed base 6 and is fixedly connected to the second gear 643. The first gear 642 and the third gear 644, which mesh with the second gear 643, are respectively fixedly connected to the transmission ends of the blower fan 61 and the exhaust fan 62.

[0039] Furthermore, the self-cleaning component 63 includes a fixing plate 631, a connecting post 632, and a striking ball 633. The fixing plate 631 is fixedly installed on the side wall of the fixing base 6. The fixing plate 631 is provided with a connecting groove. The connecting post 632 passes through the connecting groove. The bottom end of the connecting post 632 is detachably connected to the striking ball 633, which contacts the top end of the slot 51. The top end of the connecting post 632 is fixedly provided with a limiting block 634. A rotating shaft 635 is rotatably installed on the fixing base 6. One end of the rotating shaft 635 is fixedly provided with an eccentric wheel 636, and the other end extends into the inner cavity of the fixing base 6 and is fixedly connected to the second gear 643.

[0040] Furthermore, the bottom of the connecting post 632 is provided with external threads, and the top of the striking ball 633 is provided with a threaded hole 637 that mates with the external threads.

[0041] Furthermore, a tension spring 638 is fitted on the connecting column 632. One end of the tension spring 638 is pressed and fixed to the bottom end of the limiting block 634, and the other end is pressed and fixed to the top end of the fixing plate 631.

[0042] In this embodiment of the application, due to the above-mentioned structure, the drive motor 641 starts and drives the second gear 643 to rotate. The rotation of the second gear 643 drives the first gear 642 and the third gear 644 to rotate, which in turn drives the blower fan 61 and the exhaust fan 62 to rotate. At this time, the blower fan 61 can dissipate heat inside the elevator, and the exhaust fan 62 can draw out the air inside the elevator. At the same time, it can draw the dust and debris accumulated in the slot 51 into the inner cavity of the cleaning plate 5 to achieve the dust removal effect. The inner cavity of the cleaning plate 5 is provided with a detachable collection box, which is convenient for cleaning and emptying the collected dust and debris.

[0043] The eccentric wheel 634 is a cylindrical block eccentrically mounted on the rotating shaft 635. During rotation, the eccentric wheel 634 will contact or separate from the bottom of the limiting block 634. The connecting column 632 is slidably engaged with the connecting groove. When the drive motor 641 starts, it will drive the second gear 643 to rotate. The second gear 643 drives the rotating shaft 635 and the eccentric wheel 636 to rotate synchronously, so that the eccentric wheel 636 contacts the bottom of the limiting block 634, and then pushes the limiting block 634 and the connecting column 632 to slide upward along the connecting groove. At the same time, the tension spring 638 is stretched. When the eccentric wheel 636 separates from the bottom of the limiting block 634, the limiting block 634 and the connecting column 632 will be reset by the spring, and then the striking ball 633 installed at the bottom of the connecting column 632 will strike the hole groove 51, so that the dust on the hole groove 51 will fall off, thereby preventing it from being blocked.

[0044] The bottom of the connecting post 632 is provided with an external thread, and the top of the striking ball 633 is provided with a threaded hole 637 that mates with the external thread, so that the user can disassemble and replace the striking ball 633.
