Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a platform-type steel belt home elevator with an anti-fall function. Background Art

[0002] Steel belt home elevators use a polyurethane material layer. No lubrication is required between the pull rope and the traction sheave. Their lifespan is 2-3 times that of traditional steel wire ropes. They are easier to bend and increase the contact area with the traction sheave. Compared with traditional elevators, they are more energy-efficient and efficient.

[0003] According to the description of a new type of anti-fall steel belt home elevator disclosed on the patent website (authorization announcement number: CN207890847U), "This utility model relates to a new type of anti-fall steel belt home elevator, including a car, a steel belt, a guide wheel, a traction wheel and a counterweight. The tail end of the steel belt is connected to the car, and the head end of the steel belt passes through the traction wheel and the guide wheel in sequence and is connected to the counterweight. The traction wheel is provided with a row of racks, and the steel belt is provided with steel belt teeth. The steel belt teeth and the rack are meshed for transmission. The traction wheel passes through both ends. Symmetrically arranged bearings are fixed to a U-shaped support frame. An electromagnet is fixed to the upper left end of the U-shaped support frame. The left outer ring of the traction sheave is provided with several cylindrical holes, and the electromagnet's push rod is located to the left of the cylindrical hole. The steel belt comprises a polyurethane coating, a steel rope, a rope loop, and a rope loop fixing frame. Several strands of steel rope are evenly distributed within the polyurethane coating. This utility model prevents the steel belt from slipping, monitors its quality in real time, and prevents the elevator from falling during power outages. It offers advantages such as anti-falling, anti-dislocation, and a long service life.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, the utility model drives the car up and down through the traction wheel, and the transmission is performed by meshing between the steel belt teeth on the steel belt and the rack on the traction wheel, thereby increasing the friction between the steel belt and the traction wheel, making the steel belt less likely to slip, and making the operation of the car more stable and accurate. In actual use, since the device uses meshing for transmission, when unexpected situations such as vibration occur, the steel belt is likely to be displaced. At the same time, the device only uses the traction wheel for transmission, which is prone to unexpected situations such as the elevator suddenly falling and hitting the top. Therefore, it is necessary to improve an anti-fall platform-type steel belt home elevator to solve the above problems. Utility Model Content
