Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically, to a car floor cleaning device. Background Technology

[0002] As a high-density area for people, the cleanliness of elevator car floors directly affects user experience and public health. To ensure the cleanliness of the elevator car floors, they usually need to be cleaned daily.

[0003] Currently, elevator car floor cleaning mainly relies on manual wiping. However, manual wiping is usually inefficient, and due to the high frequency of elevator use, the cleaning frequency is also relatively high, which greatly increases the workload of staff, is time-consuming and labor-intensive. At the same time, the cleaning process usually requires frequent elevator stops, which greatly affects the normal use of the elevator and results in a relatively poor user experience. Therefore, in view of this, we have studied and improved the existing structure to provide an elevator car floor cleaning device, in order to achieve a more practical purpose. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] Example:

[0039] Please see Figures 1-4A car floor cleaning device includes a base plate 1. At both ends of the top of the base plate 1, a swing arm 3 and a swing arm 4 are rotatably connected via a pivot 2. A cleaning head 5 and a cleaning head 6 are respectively installed at one end of the swing arm 3 and the swing arm 4. The bottom end of the pivot 2 on the swing arm 3 extends to the bottom of the base plate 1 and is fixedly connected to a connecting rod 7. The bottom end of the pivot 2 on the swing arm 4 extends to the bottom of the base plate 1 and is fixedly connected to a connecting rod 8. A bearing seat 9 is fixedly connected to the bottom of the base plate 1. A drive shaft 10 is rotatably connected to the bearing seat 9. A drive mechanism 11 is provided at the bottom end of the drive shaft 10. A connecting rod 3 12 is fixedly connected to the top end of the drive shaft 10. A connecting rod 4 13 is rotatably connected to the connecting rod 3 12 and the connecting rod 7 via a pin. A connecting rod 5 14 is rotatably connected to the connecting rod 7 and the connecting rod 2 8 via a pin.

[0040] See Figure 3 The cleaning head 5 includes a mounting base 501 fixed to one end of the swing arm 3, and a short wiping plate 502 is snapped into the bottom of one end of the mounting base 501.

[0041] See Figure 3 The cleaning head 26 includes a mounting base 2601 fixed to one end of the swing arm 24, and a long wiping plate 602 is snapped into the bottom of one end of the mounting base 2601.

[0042] See Figure 4 The drive mechanism 11 includes two bearing seats 1101 fixed to the bottom of the base plate 1, a worm gear 1102 fixed to the bottom end of the transmission shaft 10, and a drive motor 1103 fixedly installed at the bottom of the base plate 1. A worm 1104 is rotatably connected between the two bearing seats 1101. The worm gear 1102 is meshed with the worm 1104. The output shaft of the drive motor 1103 is connected to one end of the worm 1104 through a coupling.

[0043] See Figure 4 One end of connecting rod 4 13 is rotatably connected to the end of connecting rod 1 7, and one end of connecting rod 2 8 is rotatably connected to the middle of connecting rod 1 7.

[0044] See Figure 1 Protective covers 15 are fixedly connected to both ends of the top of the base plate 1. The protective covers 15 are located above the swing rod 3 and the swing rod 4.

[0045] Working principle: When the elevator car floor needs cleaning, the drive motor 1103 is started. Under the transmission action of the worm gear 1102 and worm 1104, the drive motor 1103 drives the connecting rod 13 to rotate. The connecting rod 12 is connected to the connecting rod 7 through the connecting rod 13, and the connecting rod 8 is connected to the connecting rod 7 through the connecting rod 14. Thus, with the linkage between the connecting rods 7, 8, 12, 13, and 14, the swing rods 3 and 4 can rotate along the rotating shaft 2, allowing the cleaning heads 5 and 6 to perform reciprocating swinging motions. This enables automatic wiping of the top surface of the car floor 1, realizing the function of automatic cleaning without stopping the elevator. This ensures the normal operation of the elevator, reduces the workload of staff, and greatly improves cleaning efficiency.
