Description

Elevator pit cleaning device

Technical Field

The utility model belongs to the technical field of cleaning equipment, and particularly relates to an elevator pit cleaning device.

Background

An elevator pit refers to the space at the bottom of an elevator hoistway, typically below an elevator car. The elevator pit provides a space for mounting elevator components such as suspension devices, guide rails, counterweights, etc. In addition, the elevator pit can also accommodate a protective device when the elevator falls. The elevator pit must be designed with safety considerations in mind. The depth of the pit should be sufficient to accommodate the buffer when the elevator falls and to avoid injury to passengers. In addition, the pit interior should be clean, unobstructed, and maintain good lighting conditions so that maintenance and service personnel can safely enter.

For the cleanness and sanitation of the elevator pit, as the elevator pit is usually positioned underground, a little garbage and sundries can fall into the pit through gaps of the elevator in the daily use process of the elevator, and the pit is required to be cleaned regularly so as to accumulate dirt and bacteria on the surface for breeding, thereby being convenient for the daily maintenance of maintenance staff.

At present, the elevator pit is simple in cleaning mode, and the cleaning tools such as a broom, a shovel and the like are utilized to clean and treat the garbage in the elevator pit so as to maintain daily cleaning of the elevator pit. However, in the cleaning process, the biggest problem is the dust emission problem, because the elevator pit bottom does not possess ventilation system, can all produce a large amount of dust emission at every turn when cleaning, and cleaning personnel also can use water to spill subaerial in order to avoid the dust emission problem, but through the method of watering, the too much turbid liquid that leads to dust and water to combine after influences clean efficiency, and the too little dust suppression effect of watering is not good.

Therefore, the application provides an elevator pit cleaning device with better dust suppression effect, which is used for solving the problems.
