Abstract
The invention aims to provide a magnetic levitation type elevator door lower guide device which comprises a sill provided with a chute and guide shoes arranged at the lower part of an elevator door, wherein the two side walls of the chute are provided with magnets, the guide shoes are arranged in the chute, the two side surfaces of the guide shoes are provided with magnets, and the magnets on the side surfaces of the guide shoes are homopolar opposite to the magnets on the side walls of the opposite chute and leave a gap. Because the homopolar repulsion characteristic of the magnets, the guide shoes and the sills are not in direct contact, friction and noise are avoided in the elevator door opening and closing process, friction loss is avoided in long-term use, guide shoes are not required to be replaced, and the maintenance cost of the elevator door is reduced.
Description
Technical Field
The invention belongs to the technical field of elevators, and particularly relates to a magnetic levitation type elevator door lower guide device.
Background
At present, the elevator door is generally hung on a supporting frame at the upper part and connected with a traction system, and a guide shoe is arranged at the lower part to be matched with a sill for limiting. In the prior art, the elevator door guide shoe and the sill groove are matched in a sliding mode, the elevator door guide shoe is made of plastics such as nylon, rubber and Teflon, noise can be generated in the operation process of the elevator door, the plastic piece slides for a long time to wear and cause the elevator door to shake in the opening and closing process, and the elevator door can be prevented from being damaged after being worn by timely inspection and replacement.
Disclosure of Invention
The invention aims to solve the technical problem of providing a friction-free magnetic levitation type elevator door lower guide device.
In order to solve the technical problems, the invention is realized by the following technical scheme: the utility model provides a magnetic levitation type elevator door lower part guider, is including the sill that is equipped with the spout and install in the guide shoe of elevator door lower part, the both sides wall of spout is equipped with the magnet, guide shoe locates in the spout, guide shoe's both sides face is equipped with the magnet, guide shoe on the side magnet homopolar relative and leave the clearance with the magnet on the opposite spout lateral wall.
Further, a magnet mounting groove is formed in the side wall of the sliding groove of the sill, and a magnet on the side wall of the sliding groove is mounted in the magnet mounting groove.
Further, a gap is reserved between the bottom surface of the guide shoe and the bottom surface of the chute.
Further, the opposite poles of the magnets on the two side walls of the chute are opposite.
The invention has the advantages that: because the homopolar repulsion characteristic of the magnets, the guide shoes and the sills are not in direct contact, friction and noise are avoided in the elevator door opening and closing process, friction loss is avoided in long-term use, guide shoes are not required to be replaced, and the maintenance cost of the elevator door is reduced.
Drawings
The invention is further described below with reference to the accompanying drawings.
FIG. 1 is a schematic cross-sectional view of the present invention;
FIG. 2 is a schematic cross-sectional view of a sill according to the present invention;
in the figure: 1. a sill; 2. a chute; 3. a guide shoe; 4. an elevator door; 5. a magnet; 6. and a magnet mounting groove.
Detailed Description
The invention is described in detail below with reference to the attached drawings and detailed description:
as shown in fig. 1 and 2, the elevator comprises a sill 1 and a guide shoe 3, wherein the sill 1 is provided with a sliding groove 2, the guide shoe 3 is arranged in the sliding groove 2, and the upper part of the guide shoe 3 is fixedly connected to an elevator door 4. The upper part of the elevator door 4 is suspended and fixed, and a gap is reserved between the bottom surface of the guide shoe 3 and the bottom surface of the chute 2. The two side walls of the chute 2 are respectively provided with a magnet mounting groove 6, a magnet 5 is mounted in each magnet mounting groove 6, the magnets 5 are completely embedded into the side walls of the chute 2, and the opposite poles of the magnets 5 on the two side walls of the chute 2 are opposite. Magnets 5 are also mounted on both sides of the guide shoe 3, and the magnets 5 on the side of the guide shoe 3 are homopolar opposite to the magnets 5 on the opposite side wall of the chute 2.
The invention utilizes the principle of like pole repulsion to limit the guide shoe, the guide shoe and the sill are not in direct contact, no friction exists in the running process, the problems of friction loss, running noise and the like between the guide shoe and the sill are solved once and for all, and compared with the rolling fit or sliding fit in the prior art, the progress is obvious.
It is emphasized that: the above embodiments are merely preferred embodiments of the present invention, and the present invention is not limited in any way, and any simple modification, equivalent variation and modification made to the above embodiments according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
