Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning devices, and more specifically, to a cleaning device between an elevator door and a sill. Background Art
[0002] Modern elevators are mainly composed of traction machines (winch), guide rails, counterweight devices, safety devices (such as speed limiters, safety clamps and buffers, etc.), signal control systems, cars and hall doors, etc. These parts are installed in the shaft and machine room of the building respectively. Usually, wire rope friction transmission is adopted. The wire rope is passed around the traction wheel, and the two ends are connected to the car and the counterweight respectively. The motor drives the traction wheel to lift the car. Elevators require safety and reliability, high transportation efficiency, accurate leveling and comfortable riding. The basic parameters of the elevator mainly include rated load, number of passengers, rated speed, car outline dimensions and shaft type. There is a gap between the elevator and the sill. After long-term use of the elevator, dust will be stored in it. It is very inconvenient to clean it manually, and a specific cleaning device is required for cleaning.

[0004] However, the above application also has shortcomings. The dust collection bin of the patent is parallel to the connecting pipe, which easily causes dust to flow back and fall to the ground, resulting in repeated cleaning. Utility Model Content
[0005] The utility model aims to provide a cleaning device between an elevator door and a sill, which can efficiently collect dust after cleaning and avoid backflow.
[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a cleaning device between an elevator door and a sill, including an air pump, a casing, and a connecting pipe. The casing is fixedly connected to the connecting pipe. A dust reduction bin is provided at one end of the connecting pipe close to the air pump. The output end of the air pump is fixedly connected to the dust reduction bin. A filter is provided at one end of the air pump output end close to the connecting pipe. A dust box is threadedly connected to one end of the dust reduction bin away from the filter.
[0007] By adopting the above technical solution, the dust flows from the casing to the connecting pipe, and then to the dust reduction bin, hits the filter net, falls downward under the action of gravity, and falls into the dust storage box through the conical design of the bottom of the dust reduction bin. The dust storage box and the dust reduction are connected by threads, which is convenient for later dust cleaning.
[0008] The utility model is further configured to include a frame, a motor and a rotating wheel, wherein the frame is fixedly connected to the motor, an output end of the motor is connected to the rotating wheel, the rotating wheel is rotatably connected to the casing, and bristles are arranged on the surface of the rotating wheel.
[0009] By adopting the above technical solution, the motor provides power to drive the rotating wheel, and the bristles on the rotating wheel are used to clean the gap between the elevator and the sill. At the same time, the rotating wheel of the device is designed to be parallel to the gap between the elevator and the sill, so that the staff can avoid cleaning in the middle of the elevator door. They only need to clean outside or inside the elevator to avoid danger, such as the elevator door closing suddenly.
[0010] The utility model is further configured as follows: a universal wheel is arranged at one end of the frame away from the dust box.
[0011] By adopting the above technical solution, universal wheels are added to facilitate the staff to move the device and change the cleaning site.
[0012] The utility model is further configured as follows: a handrail is provided at one end of the frame away from the air pump.
[0013] By adopting the above technical solution, an additional handrail is provided to facilitate the staff to move the device, making it more labor-saving for the staff to push the device.
[0014] The utility model is further configured as follows: an end of the air pump close to the motor is provided with an air pump plate, and the air pump plate is fixedly connected to the vehicle frame.
[0015] By adopting the above technical solution, adding an air pump plate and fixing the air pump, the operation of the entire device can be more stable.
[0016] In summary, the utility model has the following beneficial effects:
[0017] 1. The dust goes from the casing to the connecting pipe, and then to the dust suppression bin, hits the filter net, and falls down under the action of gravity. It passes through the conical design at the bottom of the dust suppression bin and falls into the dust storage box. The dust storage box and the dust suppression are connected by threads, which is convenient for cleaning dust later;
[0018] 2. Design the runner to be parallel to the gap between the elevator and the sill to avoid workers cleaning in the middle of the elevator door. They only need to clean outside or inside the elevator to avoid danger, such as the elevator door closing suddenly. BRIEF DESCRIPTION OF THE DRAWINGS
