Description

Technical Field

[0001] The utility model belongs to the technical field of elevator cleaning, and particularly relates to an elevator traction wheel oil stain removing device. Background Art

[0002] Elevators have become an important means of transportation in people's daily work and life, and the safe operation of elevators has increasingly attracted people's attention. In order to ensure the safe operation of elevators and extend their service life, the matching inspection and daily lubrication and maintenance between the elevator traction steel wire rope and the elevator traction wheel are extremely important tasks. Excessive lubrication of the traction steel wire rope will result in a low traction coefficient of the elevator, while insufficient lubrication will lead to increased wear of the traction steel wire rope and an increase in the traction coefficient. Both situations will cause a reduction in the safety factor of the elevator.

[0003] During the daily lubrication and maintenance and use of the traction steel wire rope, since the traction wheel and the traction steel wire rope will adhere to dust and floating dust in the air, after reaching a certain operation cycle, oil stains and sludge will accumulate on the traction wheel. Timely removal of the oil stains and sludge on the traction wheel is an important measure to ensure the normal lubrication of the elevator traction system and select an appropriate traction coefficient. The traditional method for removing oil stains from the traction wheel usually involves two full-time maintenance personnel cooperating with each other to regularly clean the traction wheel. One person operates the elevator for maintenance running, and the other person uses tools such as copper wire brushes and wooden scrapers at the elevator traction wheel to manually remove the oil stains in the traction wheel grooves. However, this manual method of removing oil stains not only wastes manpower and time, but also poses a risk of being squeezed by the traction steel wire rope during the operation. Sometimes, due to the complexity of the work, there may also be a safety hazard of forgetting to remove the oil stains, resulting in poor elevator operation. Summary of the Utility Model

[0004] Aiming at the above deficiencies of the prior art, the purpose of the utility model is to provide an elevator traction wheel oil stain removing device, which can remove the oil stains on the elevator traction wheel, reduce the work burden, and at the same time avoid the operation risk of manually removing the oil stains on the elevator traction wheel, and reduce the safety hazards of elevator operation.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] The oil stain removal device for the elevator traction wheel described in this utility model includes a carbon fiber brush composed of carbon fiber bundles and a brush base. A slider is fixed at the bottom of the brush base. The slider is arranged in a slide table through a guide shaft and a lead screw. The slide table includes a slide table support frame and a slide table bottom plate at the bottom of the slide table support frame. Both ends of the guide shaft and the lead screw are fixed on the slide table support frame; the slide table is arranged on a carbon fiber bottom plate.

One end of the first hinge rod far from the first hinge seat is rotatably connected to a second hinge rod. A second hinge seat is arranged at the bottom of the carbon fiber bottom plate, and the second hinge rod is hinged inside the second hinge seat.

[0016] The described heavy-duty magnetic base is a rectangular magnetic base, and the suction force of the heavy-duty magnetic base is 200 - 500 kg.

[0017] The beneficial effects of the present utility model are as follows:

[0036] The milling machine workpiece locator 11 includes a first articulated seat 1101 arranged on the heavy-duty magnetic base 12. A first articulated rod 1102 is articulated on the first articulated seat 1101. One end of the first articulated rod 1102 far from the first articulated seat 1101 is rotatably connected to a second articulated rod 1103.

The length of the carbon fiber bundle 1 is preferably 80 mm, the width of the carbon fiber bundle 1 is preferably 150 mm, and the thickness of the carbon fiber base plate 16 is preferably 3 mm to ensure the stiffness and elasticity of the carbon fiber bundle 1, so that the carbon fiber bundle 1 can independently extend into the groove of the traction wheel, the carbon fiber bundle 1 can cover the width of the traction wheel, and the carbon fiber base plate 16 made of carbon fiber material can not only ensure the strength of the device but also reduce the total mass of the device.

[0039] Working principle and process:

[0040] When the device is in use, it is adsorbed on the appropriate position of the load-bearing beam of the elevator traction machine through the heavy-duty magnetic base 12, and the angle of the milling machine workpiece locator 11 is adjusted. After the device is installed, the maintenance switch 1303 is connected to the controller, and finally the power plug of the controller is connected to the 220V power supply in the elevator machine room, and the power switch 1304 is started.

[0041] When the clock timing of the single-chip microcomputer control system 1301 in the controller exceeds 10 days and the maintenance switch 1303 is detected to be turned on, the controller controls the stepper motor 3 to move, thereby driving the lead screw to move, so that the slider 15 on the lead screw can move along the direction of the guide shaft 14. When the brush holder 2 touches the second limit switch 17, the stepper motor 3 stops running. At this time, the carbon fiber bundle 1 can extend into the groove of the traction sheave, and the elevator in the maintenance state runs at the maintenance speed. The carbon fiber bundle 1 can clean the oil stain in the groove of the traction sheave. After the cleaning is completed, the maintenance switch 1303 is turned off. After the single-chip microcomputer control system 1301 in the controller detects that the maintenance switch 1303 is turned off, it controls the stepper motor 3 to move in the reverse direction, so that the lead screw drives the slider 15 to move in the reverse direction, ensuring that the carbon fiber bundle 1 completely leaves the groove of the traction sheave. When the brush holder 2 touches the first limit switch 10, the stepper motor 3 stops running, and at the same time, the date and time of this oil stain removal are recorded, and the controller enters the low-power standby state.
