Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a clean elevator. Background Art

[0002] A clean elevator is a method of cleaning the elevator to ensure a constant cleanliness level within the cabin. In the vertical transportation of personnel or products in multi-story factories, the design of a clean elevator is crucial to prevent product quality degradation from external contamination or to ensure the air quality of the clean rooms connected to the elevator.

[0003] For example, the authorization announcement number CN113023529B discloses a high-efficiency clean elevator. With the development of the national economy and the continuous improvement of science and technology, clean factories, laboratories, research rooms and clean hospitals with higher standards have become indispensable workplaces. Although these workplaces are equipped with many facilities to improve cleanliness, the entry and exit of goods and equipment must be cleaned multiple times. When ordinary elevators are used to transport equipment or items with cleanliness requirements, the equipment and items will come into contact with unclean air, causing pollution to the transported items. In this high-efficiency clean elevator, the steel beam on the top of the car is connected to the dust removal traction device, which scrapes away iron filings and other materials generated during the traction process through a brush, and then is adsorbed by the steel shield and magnet into the bottom cover to prevent metal dust from entering the interior of the car and the inside of the shaft to cause pollution.

[0004] However, existing clean elevators all have a circulating filter component installed on the top of the elevator car to complete the circulation and disinfection inside the elevator. However, during maintenance, maintenance personnel need to step on the top of the elevator for support, which will cause the top component of the elevator to be stepped on and damaged. At the same time, the top component of the elevator will hinder the movement of maintenance personnel, so a fall accident may occur if they are not careful. Utility Model Content

[0028] Through the above solution, the connecting plates can be fixed to both ends of the elevator car by connecting screws, so that the supporting plate is fixed to the top of the elevator car.

[0029] In this embodiment, preferably, a driving machine 205 is fixedly installed in the middle of the front end of the support plate 202, a first rotating card wheel 206 is fixedly installed at the front end of the driving machine 205, and a belt 301 is movably installed on the first rotating card wheel 206.

[0030] According to the above solution, the first rotating pulley can be driven to rotate by the rotation of the driving machine, so that the belt starts to rotate.

[0031] In this embodiment, preferably, a second rotating pulley 302 is movably installed inside the left end of the belt 301, and the second rotating pulley 302 is fixedly installed on the left side of the front end of the support plate 202. Rotating wheels 303 are fixedly installed on both sides of the front end of the support plate 202.

[0032] According to the above solution, the belt can be supported and rotated back and forth by the second rotating pulley, and the cable can be pulled back and forth inside the pulley by the rotating wheel.

[0033] In this embodiment, preferably, a cable 304 is movably installed in the middle of the rotating wheel 303, one end of the cable 304 is fixedly installed on the first vertical rod 305, a belt 301 is fixedly installed on the upper side of the first vertical rod 305, and the other end of the cable 304 is fixedly installed on the second vertical rod 306, and the first vertical rod 305 and the second vertical rod 306 are fixedly installed on the top of the elevator door 401.

[0034] With the above solution, the first vertical rod is moved by the belt, so that the cable is driven to rotate on the rotating wheel, thereby driving the second vertical rod to move in a direction opposite to the first vertical rod, thereby driving the elevator door.

[0035] In this embodiment, preferably, a sliding wheel 402 is fixedly installed on the lower side of the rear end of the elevator door 401, and the sliding wheel 402 is movably installed in a sliding groove 403, and the sliding groove 403 is opened on the lower side of the front end of the support plate 202.

[0036] Through the above solution, the elevator door is driven to cause the sliding wheel to slide in the sliding groove, so that the elevator door is opened and closed.

[0037] In this embodiment, preferably, the cleaning mechanism 103 includes a disinfection filter box 404, a mounting plate 405 is fixedly installed at the bottom end of the disinfection filter box 404, a mounting screw 406 is movably installed on the mounting plate 405, and a pump air bin 501 is fixedly installed at the front end of the disinfection filter box 404.

[0038] Through the above solution, the mounting plate can be fixed by installing screws, thereby completing the installation of the disinfection filter box.

[0039] In this embodiment, preferably, a driver 502 is fixedly installed on the left end of the pump air bin 501 , a suction pipe 503 is fixedly installed on the right end of the pump air bin 501 , and the driver 502 and the suction pipe 503 are fixedly installed on the top of the elevator car 104 .

[0040] Through the above scheme, the driver can work to enable the pump air bin to extract the air in the elevator car through the suction pipe and pump it into the disinfection filter box. The disinfection filter box disinfects, sterilizes and filters the air and then discharges it into the elevator car, completing the cycle disinfection and filtration in the elevator car, thereby making the elevator car meet the cleanliness standards.

[0041] When the clean elevator of this embodiment is in use, the driving machine 205 drives the first rotating card wheel 206 to rotate, so that the belt 301 starts to rotate outside the first rotating card wheel 206 and the second rotating card wheel 302. When the belt 301 rotates, the first vertical rod 305 is driven to move. One end of the first vertical rod 305 is connected to the cable 304, so when it moves, it drives the cable 304 to rotate on the rotating wheel 303. The other end of the cable 304 is connected to the second vertical rod 306. Therefore, when the first vertical rod 305 moves, it drives the second vertical rod 306 to move in the opposite direction, thereby driving the elevator door 401 to start moving in the sliding groove 403 through the sliding wheel 402, so that the elevator door 401 is opened and closed. After the elevator is opened, when the user enters, the driving machine 205 drives the pump air bin 501 to work, so that the suction pipe 5 03 The air inside the elevator is extracted, and then the air is pumped into the disinfection filter box 404 through the pump air bin 501. After filtering, the disinfection filter box 404 discharges the clean air into the elevator car 104 through its bottom, thereby completing the air circulation purification and disinfection so that the interior of the elevator reaches the cleanliness standard. When the elevator is under maintenance, the maintenance personnel support the top of the elevator with the protective cover 105 for maintenance. There is no obstacle on the top of the protective cover 105, which can prevent the maintenance personnel from tripping and falling. Then the cover door 201 on the top of the protective cover 105 is opened, so that the maintenance personnel can maintain the disinfection filter box 404. The protective cover 105 plays a supporting and protective role, which can prevent the maintenance personnel from stepping on the disinfection filter box 404 or other elevator components during maintenance, and at the same time can support the inspection personnel to avoid tripping and falling.
