Description

Technical Field

[0001] The invention belongs to the technical field of elevator wire rope maintenance, and in particular relates to an automatic cleaning device for elevator wire ropes. Background Art

[0002] Elevator wire rope is a key component in the elevator system that connects the elevator car and counterweight. During long-term use, elevator wire rope will inevitably accumulate dust, oil and other impurities. These dirt not only affects the appearance of the wire rope, but may also reduce its performance and even cause safety hazards. Therefore, regular cleaning and maintenance of elevator wire rope is necessary for the safe operation of elevators.

[0003] Normally, the cleaning device of the elevator wire rope consists of two brushes, which are fixed at the bottom of the wire rope retracting and unwinding roller. When the elevator wire rope is running, the brushes contact the surface of the wire rope and remove the oil and dust on the surface through friction. However, this traditional cleaning method has certain limitations. Since the brush can only clean the wire rope through surface friction when the wire rope is running, this single cleaning cannot completely remove the dirt on the surface of the wire rope. Therefore, in order to achieve thorough cleaning, it is necessary to control the movement of the wire rope multiple times to ensure that the dirt on its surface is completely removed. Summary of the invention

[0004] The invention aims to solve the problem that dirt on the surface of the steel wire rope cannot be completely removed by brushing the steel wire rope with two fixed brushes during its running process.

The dirt temporary storage box and the bellows are respectively installed at the bottom of the two cleaning plates. The air outlet of the bellows faces the inlet of the dirt temporary storage box. The bellows is used to blow the dirt cleaned by the scrubbing mechanism into the dirt temporary storage box.

[0006] Furthermore, the lifting mechanism includes a supporting box and a lifting plate. The supporting box is fixed on the connecting frame. A lifting drive assembly is arranged on the top of the supporting box. Two slide rails are installed on the vertical surface of the supporting box. The lifting plate is slidably assembled between the two slide rails. The lifting drive assembly is connected to the lifting plate to drive the lifting plate to move up and down. The brushing mechanism is connected to the lifting plate and moves with the lifting plate.

[0007] Further, the lifting drive assembly includes an L-shaped bracket, a crankshaft and a second motor; The vertical frame of the L-shaped bracket is fixed on the supporting box body, the horizontal frame of the L-shaped bracket is equipped with an axle seat, the central axis of the crankshaft is assembled on the axle seat, the eccentric axis of the crankshaft is connected with a lifting rod, the lower end of the lifting rod is hinged with a bottom connecting block, and the bottom connecting block is fixedly connected to the lifting plate; The second motor is installed on the L-shaped bracket, a driving pulley is installed on the output shaft of the second motor, a driven pulley is installed on the central axis of the crankshaft, and a belt is connected between the driving pulley and the driven pulley.

[0008] Furthermore, the left cleaning plate of the two cleaning plates of the scrubbing mechanism is fixed on the lifting plate, a transverse sliding groove is provided on the lifting plate, and a supporting sliding plate is connected to the right cleaning plate through an upper limit block and a lower limit block; the right cleaning plate is slidably assembled on the lifting plate through the supporting sliding plate sleeve in the transverse sliding groove; A motor, a screw and a screw slider are installed at the bottom of the support box.

[0009] Furthermore, the interior of the supporting box is hollow and serves as a storage bin for cleaning agent, and a water pipe is connected to the supporting box; The cleaning plate comprises an outer support frame, in which cleaning rollers arranged side by side in an upper and lower direction are installed, and bristles are distributed on the cleaning rollers; A cleaning agent pipe and a blower are installed outside the outer support frame. The outlet of the cleaning agent pipe is located between the cleaning rollers, the inlet of the cleaning agent pipe is connected to the water pipe, and the blower is connected to the air outlet of the cleaning agent pipe.

[0010] Furthermore, a push roller is arranged in the dirt temporary storage box, and the push roller is connected to the torque output mechanism outside the dirt temporary storage box, and a discharge bin is arranged under the bottom outlet of the dirt temporary storage box; the discharge bin includes a discharge bin outer frame and a discharge hopper, and a drawer-type matching structure is formed between the discharge hopper and the discharge bin outer frame.

Therefore, when the two cleaning plates are close to the wire rope, the bristles automatically adapt to the texture of the wire rope winding; and through the set blower, the cleaning agent can be evenly sprayed on the surface of the wire rope. At the same time, the wind pressure of the blower blows the cleaning agent in the cleaning agent pipe onto the wire rope, which helps the cleaning agent to better penetrate and clean the wire rope, thereby improving the cleaning efficiency.

[0015] 2. A dirt collection mechanism is provided at the bottom of the cleaning plate. The dirt collection mechanism consists of a bellows that provides wind pressure and a dirt temporary storage box that collects dirt. The bellows blows the dirt into the dirt temporary storage box, collects and stores the cleaned dirt in time, and avoids secondary pollution.

[0016] 3. The lifting mechanism can drive the brushing mechanism to move along the length of the wire rope, and the cleaning plate brushes the wire rope back and forth.

[0017] 4. The design of the entire cleaning device fully considers the special structure and cleaning requirements of the elevator wire rope. Through precise mechanical control and reasonable material selection, efficient and automatic cleaning of the wire rope is achieved. The device not only improves the cleaning efficiency and reduces the tediousness of manual operation, but also helps to extend the service life of the wire rope and ensure the safety of elevator operation.
