Description
Technical Field
[0001] The utility model relates to a component for a window cleaning machine, in particular to a simple straight arm head with a material hanging point. Background Art
[0002] During the rotation of the existing straight arm head installed on the telescopic arm of the window cleaning machine, the rotation of the slewing bearing is not flexible, and it is difficult to adjust the posture of the gondola to the appropriate position, which is difficult to meet the cleaning and maintenance requirements of the curtain wall. In addition, when the driving motor installed on the slewing bearing encounters an obstacle during the rotation process, the straight arm head cannot rotate properly, and the posture of the gondola cannot be adjusted properly, which is also difficult to meet the cleaning and maintenance requirements of the curtain wall. Moreover, the existing straight arm head is inconvenient for operators in the gondola to take materials. Utility Model Content
[0003] The utility model provides a simple straight arm head with a material lifting point.
[0004] The utility model aims to solve the problems that the straight arm head on the telescopic arm of the existing window cleaning machine is not flexible in rotation and cannot be rotated in place, so that the posture of the hanging boat cannot be adjusted in place, and it is inconvenient for operators in the hanging boat to take materials.
[0005] The technical solution adopted by the utility model to solve the technical problem is: a simple one-arm head with a material lifting point, including a slewing bearing, a one-arm connected to the slewing bearing, and two ends of the one-arm are respectively provided with a crane anti-collision top limit frame. The middle part of the one-arm is provided with a material lifting point assembly, and the material lifting point assembly includes a pulley frame, a lifting point pulley and a material anti-collision top limit frame. The pulley frame is fixed on the one-arm and located below the slewing bearing, the lifting point pulley is arranged on the pulley frame, and the material anti-collision top limit frame is installed at the front end of the pulley frame.
[0006] Preferably, a first guide rope pulley and a second guide rope pulley are respectively provided at two ends of the straight arm.
[0007] Preferably, the slewing bearing is a worm gear slewing bearing, and two drive motors are arranged on the worm gear slewing bearing. The drive motor is connected to the worm, and the worm is meshed with the worm wheel.
[0008] The beneficial effects of the utility model are as follows: the utility model realizes the rotation of the arm head through the drive motor and the slewing bearing, thereby adjusting the posture of the gondola to meet the cleaning and maintenance requirements of the curtain wall. The utility model adopts a worm gear slewing bearing to be linked with the drive motor. During the rotation process, the position of the drive motor remains unchanged, and only the arm head rotates, which prevents the drive motor from encountering obstacles during the rotation process, ensures the continuous rotation of the arm head, and thus adjusts the posture of the gondola to meet the cleaning and maintenance requirements of the curtain wall. The worm gear structure of the worm gear slewing bearing of the utility model also has a self-locking function, which can keep the arm head in a fixed position to prevent the arm head from sliding.

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] As shown in the figure, the utility model discloses a simple one-arm head with a material lifting point, comprising a slewing bearing 3, an one-arm 4 connected to the slewing bearing 3, and two ends of the one-arm 4 are provided with a hanging boat anti-collision top limit frame 5 and a hanging boat anti-collision top limit frame 5, respectively. The middle part of the one-arm 4 is provided with a material lifting point assembly, and the material lifting point assembly includes a pulley frame 7, a lifting point pulley 8 and a material anti-collision top limit frame 9. The pulley frame 7 is fixed on the one-arm 4 and is located below the slewing bearing 3. The lifting point pulley 8 is provided on the pulley frame 7, and the material anti-collision top limit frame 9 is installed at the front end of the pulley frame 7.
[0014] The two ends of the arm 4 are respectively provided with a first guide rope pulley 11 and a second guide rope pulley 12. The first guide rope pulley 11 and the second guide rope pulley 12 are respectively connected to the two ends of the arm 4 through bearings. The slewing bearing 3 is a worm-gear slewing bearing, and the lower two sides of the worm-gear slewing bearing are respectively provided with a driving motor 1 and a driving motor 6, and the driving motor 1 and the driving motor 6 are respectively connected to the worm, and the worm is meshed with the worm wheel. The slewing bearing 3 includes an inner ring and an outer ring, and the outer ring of the slewing bearing 3 is connected to the telescopic arm of the window cleaning machine through the upper ring screw 2, and the inner ring of the slewing bearing 3 is connected to the arm 4 through the lower ring screw 13.
[0015] The working principle of the utility model is as follows: the utility model realizes the rotation of the arm 4 through the drive motor 1, the drive motor 6 and the slewing bearing 3, thereby adjusting the posture of the hanging boat to meet the cleaning and maintenance requirements of the curtain wall. The utility model adopts a turbine worm slewing bearing to be linked with the drive motor 1 and the drive motor 6. During the rotation process, the positions of the drive motor 1 and the drive motor 6 remain unchanged, and only the arm 4 rotates, which prevents the drive motor 1 and the drive motor 6 from encountering obstacles during the rotation process, and ensures the continuous rotation of the arm 4, thereby adjusting the posture of the hanging boat to meet the cleaning and maintenance requirements of the curtain wall. The worm gear structure of the turbine worm slewing bearing of the utility model also has a self-locking function, which can keep the arm 4 in a fixed position to prevent sliding. The first guide rope pulley 11 and the second guide rope pulley 12 of the utility model are driven by bearings with the arm 4 to ensure the flexibility of the transmission. The crane anti-top impact limit frame 5 and the crane anti-top impact limit frame 5 configured in the utility model are used to prevent the crane of the window cleaning machine from top impacting upward. The material anti-top impact limit frame 9 equipped in the utility model prevents material from top impacting, thereby ensuring the safety of the window cleaning machine.
