[0024] like Figures 1 to 3 As shown, an elevator running guide rail includes a car guide rail 1, which is hollow. The car guide rail 1 is made of aluminum profile, which has low density and light weight. The light weight greatly reduces the transportation cost and reduces manpower consumption. According to the structural and strength requirements, the hollow cavity is designed and the reinforcing ribs are reasonably arranged to meet the strength requirements of operation. A mounting guide rail with a hollow setting is welded on one side of the car guide rail 1 close to the slide groove 5. Two adjacent car guide rails 1 are connected by profiles 3 and bolts. The profiles 3 are located at the mounting guide rail. In the guide rail, the side of the car guide rail 1 away from the slide groove 5 and the side adjacent to the slide groove 5 are installed with reinforcing ribs 6. The design of the reinforcing ribs 6 prevents the car guide rail 1 from deformation during the operation of the car. The reinforcing ribs 6 are poured into the reserved groove by concrete. A crossbeam 4 is arranged on the other side of the car guide rail 1. The crossbeam 4 is connected to the shaft wall by bolts. The crossbeam 4 is fixed to the installation guide rail by a pressing guide plate and bolts. The number of crossbeams 4 is set to multiple, and multiple crossbeams 4 are set at the connection between two adjacent car guide rails 1.

[0025] like Figures 4 to 5 As shown, an elevator running guide rail also includes a guide shoe 2 for guiding the car used in conjunction with the car guide rail 1, a track is opened on the car guide rail 1 for the guide shoe 2 to roll on the slide groove 5, the guide shoe 2 includes a mounting plate 201, the mounting plate 201 is rotatably connected to a guide wheel 202 through a bearing, and a cleaning brush 7 for wiping dust particles is arranged on the outer side of the guide wheel 202; a driving assembly is arranged on the side of the cleaning brush 7 close to the car, and the cleaning brush 7 is driven to reciprocate by the driving assembly.

[0026] The driving assembly includes a reciprocating screw rod 205, which is rotatably connected to the mounting plate 201, and a motor is connected to one end of the reciprocating screw rod 205 away from the mounting plate 201, and the motor is mounted on the mounting plate 201. The outer side of the reciprocating screw rod 205 is connected to the moving rod 204 through a nut pair, and the cleaning brush 7 is installed on the side of the moving rod 204 away from the car;

[0027] A limiting rod 203 is fixedly connected to the rotating shaft of the guide wheel 202 , and the limiting rod 203 penetrates the moving rod 204 and is movably connected to the moving rod 204 .

[0028] During specific operation, three guide wheels 202 are arranged on the guide shoe, and each guide wheel 202 is located in the slide groove 5 and is in rolling contact with the inner wall of the slide groove 5. In order to reduce the friction force when the guide wheel 202 contacts the car guide rail 1, reduce wear and noise, lubricating oil is usually applied to the surface of the guide wheel 202. During the operation of the elevator, the dust particles in the hoistway will adhere to the surface of the guide wheel 202 after the lubricating oil is applied. If it is not cleaned in time, it will cause wear of the guide wheel 202. In order to reduce the wear of the guide wheel 202, the motor can be started regularly, and the motor drives the reciprocating screw 205 to rotate. The reciprocating screw 205 rotates to drive the moving rod 204 to be limited by the limit rod 203 and move toward When the guide wheel 202 moves in the direction of the guide wheel 202, the moving rod 204 moves, driving the cleaning brush 7 connected thereto to move, so that the three cleaning brushes 7 are respectively located on one side of the guide wheel 202. When the elevator car runs again, the guide wheel 202 rolls, and the cleaning brush 7 arranged on one side of the guide wheel 202 can be used to wipe off the dust particles stuck to the outer surface of the guide wheel 202. After the surface of the guide wheel 202 is wiped clean by the cleaning brush 7, the motor can be started again, and the cleaning brush 7 is reset by the motor drive. By setting the cleaning brush 7 and the driving component, the dust particles stuck on the surface of the guide wheel 202 are cleaned regularly, thereby reducing the wear on the surface of the guide wheel 202 and increasing the service life of the guide wheel 202.

[0029] like Figure 6 As shown, one side of the mounting plate 201 is connected to a protective cover 8 via a connecting rod, the side of the protective cover 8 facing the cleaning brush 7 is fully open, and the end of the moving rod 204 close to the protective cover 8 passes through the protective cover 8 and slidably cooperates with the protective cover 8.

[0030] During specific operation, a protective cover 8 connected to the mounting plate 201 is provided above the cleaning brush 7. A scraper is bent on the inner wall of the protective cover 8 on one side close to the cleaning brush 7. When the cleaning brush 7 is driven toward the protective cover 8 by the driving assembly, the scraper can be used to scrape off the dust on the surface of the cleaning brush 7 and then the cleaning brush 7 can be stored in the protective cover 8. Through the setting of the protective cover 8 and the scraper, after the cleaning brush 7 cleans the dust on the surface of the guide wheel 202, the surface of the cleaning brush 7 can be cleaned during the storage process of the cleaning brush 7, thereby increasing the number of times the cleaning brush 7 is used and reducing the replacement frequency of the cleaning brush 7.
