Description

Technical Field

[0001] This utility model relates to the field of wire rope maintenance technology, and in particular to a wire rope maintenance device for elevators. Background Technology

[0002] Elevator wire ropes consist of steel wires, a core, and lubricant. Multiple layers of steel wires are twisted into strands and then wound into a spiral shape around the core. Elevator wire rope maintenance involves regularly cleaning, lubricating, inspecting, and maintaining the rope to extend its service life and ensure safe operation.

[0003] A Chinese utility model patent (CN223032769U) discloses a maintenance device for elevator wire ropes, comprising a connecting mechanism and a maintenance mechanism. The maintenance mechanism is fixedly connected to the surface of the connecting mechanism and includes a propulsion unit and a spraying unit. This elevator wire rope maintenance device can be directly installed on the surface of the elevator wire rope and rotates and moves with the wire rope, ensuring comprehensive and thorough cleaning and oiling without any blind spots. It will not interfere with the normal operation of the elevator or pose any safety hazards. Furthermore, because the device acts directly on the surface of the wire rope, there is no need for manual entry into the elevator shaft, greatly reducing operational risks and improving safety. Through its rotating and moving design, the device can precisely control the intensity and scope of cleaning and oiling, avoiding excessive wear on the wire rope or omissions in maintenance areas. This precision helps extend the service life of the wire rope and maintain its good operating condition.

[0004] Referring to the aforementioned elevator wire rope maintenance device, this device cleans the wire rope by spraying water onto the surface of a cleaning roller through a cleaning nozzle. This method makes it easy for water stains to adhere to the wire rope surface, which in turn affects the adhesion of subsequent lubricant application, resulting in inadequate overall maintenance of the wire rope. Therefore, how to effectively clean dust from elevator wire ropes while avoiding interference with lubricant application is a crucial issue that needs to be addressed in the design of elevator wire rope maintenance devices. Utility Model Content

[0005] This invention provides a steel wire rope maintenance device for elevators to solve the problem that the cleaning method of steel wire rope affects the subsequent application of lubricating oil.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a steel wire rope maintenance device for elevators, including a support rod, and further comprising: a first support arc plate and a second support arc plate fixedly connected to both ends of the support rod, the first support arc plate and the second support arc plate being rotatably connected to each other;

[0014] In this technical solution, an electric push rod extends to push a sliding block to move, and the sliding block drives the traveling roller to move, so that the traveling roller is tightly pressed against the side walls on both sides of the elevator wire rope. When the motor rotates, it drives the traveling roller, and the rotation of the traveling roller drives the entire maintenance device to move along the elevator wire rope.

[0015] Preferably, the cleaning structure includes a fixed plate, a sliding rod, an electric push rod, a fixed frame, a roller brush, and a motor. The sliding rod is slidably connected to the side walls of the supporting arc plate and the supporting arc plate.

[0016] In this technical solution, the electric push rod two extends to push the fixed frame to move, and the fixed frame drives the sliding rod and the roller brush to move, so that the roller brush is attached to the side wall of the elevator wire rope. The motor two rotates to drive the roller brush to rotate. During the movement, the rotating roller brush cleans the elevator wire rope and removes the dust from the elevator wire rope.

[0017] Preferably, the sidewalls of the first and second support arc plates are provided with locking grooves.

[0019] Preferably, the threads on the threaded rods on both sides of the rotating block are opposite to each other, and the locking rod and the locking slot cooperate with each other.

[0020] In this technical solution, rotating the rotating block causes the threaded rod to rotate, which in turn causes the moving block to move. The moving block moves towards the center, causing the fixed plate to move, which in turn causes the snap-fit ​​rod to move, so that the snap-fit ​​rod snaps into the snap-fit ​​groove on the support arc plate 1 and the support arc plate 2, thus fixing the support arc plate 1 and the support arc plate 2 together.

[0021] Preferably, a fixing block is fixedly connected to the side wall of the movable block, and a threaded rod is threadedly connected to the side wall of the fixing block. A handle block is fixedly connected to the end of the threaded rod, and the threaded rod cooperates with the threaded hole.

[0022] In this technical solution, the handle block drives the threaded rod two to rotate, the threaded rod two rotates and moves, and the threaded connection is inserted into the corresponding threaded hole to fix and restrict the rotating block, so as to prevent the rotating block from rotating.

[0023] Preferably, the oil spraying structure includes an oil tank, a fixed arc plate, a round cover, an oil inlet pipe, and a connecting rod. The oil tank is fixedly connected to the top side wall of the first supporting arc plate and the second supporting arc plate.

[0025] In this technical solution, the oil pump draws in oil and injects it into the oil nozzle through the oil pipe. The oil nozzle sprays the lubricating oil onto the elevator wire rope for lubrication. The fixed arc plate blocks the splashing lubricating oil, preventing it from splashing onto other structures on the maintenance device. This effectively lubricates the elevator wire rope while preventing lubricating oil from splashing everywhere.

[0026] Preferably, the dust collection structure includes a collection housing, a collection box, a handle, a suction pipe, a ventilation tube, an exhaust fan, and a dust filter. The collection housing is fixedly connected to the top side wall of the oil tank. The collection box is slidably connected to the bottom inner side wall of the collection housing. The handle is fixedly connected to the side wall of the collection box.

The exhaust fan and the dust filter are fixedly connected to the inner side wall of the ventilation tube, and the dust filter is located on both sides of the exhaust fan.

[0027] In this technical solution, the exhaust fan draws air, causing the suction pipe to suck up the dust, which is then drawn into the collection housing by the roller brush and collected in the collection box. This effectively cleans the dust on the elevator wire rope while preventing dust from falling below and affecting the application of lubricating oil. The dustproof net prevents dust from entering the exhaust fan.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows:

[0030] 1. By rotating the rotating block, the rotating block drives the threaded rod to rotate, the threaded rod drives the moving block to move, and the moving block drives the snap-fit ​​rod to move, so that the snap-fit ​​rod snaps into the snap-fit ​​groove on the first and second support arc plates, which facilitates the fixed connection of the first and second support arc plates together.

[0031] 2. The rotating motor drives the roller brush to rotate. During the movement, the rotating roller brush cleans the elevator wire rope, removing the dust from the elevator wire rope. The exhaust fan draws air, causing the dust suction pipe to suck up the dust cleaned by the roller brush and suck it into the collection housing, where it falls into the collection box for collection. This facilitates better cleaning of the dust on the elevator wire rope while avoiding affecting the application of lubricating oil.

[0032] 3. Oil is drawn in by an oil pump and injected into the oil nozzle through the oil pipe. The oil nozzle sprays the lubricating oil onto the elevator wire rope for lubrication. The fixed arc plate blocks the splashing lubricating oil, preventing it from splashing onto other structures on the maintenance device. This facilitates better lubrication of the elevator wire rope while preventing the lubricating oil from splashing everywhere. Attached Figure Description
