Description

Technical Field

[0001] The present invention relates to the technical field of elevator maintenance, and particularly to a cleaning and lubricating device for elevator steel ropes. Background Art

[0002] The elevator steel rope is a key component in the elevator for bearing weight and transmitting power. It is usually woven from multiple steel wires to ensure that the load is evenly distributed when bearing weight. During the use of the elevator steel rope, it needs to be regularly inspected, cleaned, and lubricated. The traditional cleaning and lubricating method is to form friction between kerosene and a rag and the running steel rope to remove the previous maintenance oil and the generated sludge on the surface of the steel rope for cleaning. Subsequently, a new maintenance oil is coated on the surface of the steel rope through a sponge roller to reduce the wear, load-bearing capacity, and aging speed of the steel rope.

[0003] Since most of the steel ropes have a braided structure, textures and dead corners are formed on the surface of the steel rope. When the traditional cleaning and lubricating method is used to clean the surface of the steel rope, it is not convenient to scrape and wash the sludge and maintenance oil on the surface of the steel rope along the texture of the steel rope, resulting in insufficient cleaning of the steel rope. Moreover, during the time period between each maintenance, the temperature and humidity vary due to weather changes. After several days of cumulative effects, the adhesion strength and quantity of stains on the surface of the steel rope are different during each maintenance, and a steel brush is required to brush off the stains. However, the existing cleaning and lubricating device is difficult to adjust the brushing force according to the adhesion of stubborn stains on the surface of the steel rope, resulting in insufficient cleaning of the steel rope and thus poor cleaning effect. Summary of the Invention

[0004] In order to overcome the above disadvantages, the present invention provides a cleaning and lubricating device for elevator steel ropes, which can scrape and wash the sludge and the previous maintenance oil along the texture of the steel rope and can adjust the brushing force according to the adhesion of stubborn stains, making the cleaning of the steel rope more sufficient and thorough, and significantly enhancing the cleaning effect of the steel rope.

[0017] Further, the triggering assembly includes: oil storage tanks respectively fixedly connected to Frame 1 and Frame 2; sleeves respectively communicated with the bottoms of the two oil storage tanks; triggering pipes respectively rotatably connected to one side of the two rotating pipes, the two triggering pipes are respectively slidably connected to the two sleeves, and triggering holes are formed at the mutually remote ends of the two triggering pipes.

[0018] Furthermore, it also includes a brushing mechanism for brushing off stubborn stains on the surface of the wire rope. It is arranged between the combined frame and the semi-spraying ring. The brushing mechanism includes: semi-extrusion rings respectively fixed to the bottoms of the six semi-spraying rings, and each semi-extrusion ring is provided with a wavy groove; three brush plates respectively slidably connected to two sliding grooves, the tops of the six brush plates are respectively located in the six wavy grooves, the inside of the brush plate is provided with a cavity, and one side of the brush plate is provided with an air inlet; five brush heads respectively slidably connected to each brush plate, and the wire brushes of the brush heads are in contact with the surface of the wire rope.

[0020] The beneficial effects of the present invention are as follows: 1.

The maintenance oil uniformly penetrates into the inside of the sponge rollers through several small holes on the rotating pipe. The sponge rollers coat the maintenance oil inside on the surface of the moving wire rope, so as to lubricate the surface of the cleaned wire rope immediately and improve the efficiency.

[0021] 2. While cleaning the wire rope, the rotation of the semi-spraying ring will drive the rotation of the semi-extrusion ring. The wavy groove will squeeze the top of the brush plate, causing the brush plate to drive the brush head to move up and down reciprocally. The brush head will repeatedly brush off the relatively stubborn stains on the surface of the wire rope. At the same time, the cleaning liquid will wash off the stains brushed off by the brush head, so as to make the cleaning of the surface of the wire rope more thorough and significantly enhance the cleaning effect on the wire rope.

[0022] 3. The staff can adjust the brushing force according to the adhesion of stubborn stains on the surface of the wire rope, so as to make the cleaning of the wire rope more thorough while ensuring the service life of the brush head, thereby further enhancing the cleaning effect.

Specific embodiments

[0043] The present invention will be further described below in conjunction with the drawings and embodiments.

[0044] Embodiment 1: A cleaning and lubricating device for an elevator steel wire rope, as Figures 1-16 shown, comprising:

[0045] A traction machine 0, on the traction wheel of which three steel wire ropes 00 are wound;

[0046] A frame one 1 and a frame two 2 which are connected to each other by bolts, and are both installed on the traction machine 0;

[0047] Two symmetrically arranged combined frames 3, which are respectively welded to the frame one 1 and the frame two 2. A cavity communicating up and down is formed between the two combined frames 3. Sliding grooves 34 and three semi-circular liquid grooves 32 are opened on both of the two combined frames 3. The six semi-circular liquid grooves 32 are in contact to form three independent annular grooves. Three liquid inlet holes 31 and three liquid outlet holes 33 are opened on one of the combined frames 3. The liquid inlet holes 31 are located above the liquid outlet holes 33 and communicate with the semi-circular liquid grooves 32. The three steel wire ropes 00 all pass through the cavity between the two combined frames 3;

[0048] Six scraping wheels 4 with spiral grooves and detachable, which are used to scrape off the sludge on the steel wire rope 00 along the texture of the steel wire rope 00, are respectively rotatably connected to the upper and lower sides between the two combined frames 3. The spiral grooves of the six scraping wheels 4 are respectively in close contact with the textures of the three steel wire ropes 00;

[0049] A spraying mechanism, which is used to spray high-pressure cleaning liquid on the steel wire rope 00 along the texture of the steel wire rope 00, is arranged between the frame one 1 and the combined frame 3;

[0050] The coating mechanism, which is used to immediately coat the surface of the cleaned wire rope 00 with new maintenance oil, is arranged between the first frame 1, the second frame 2 and the pump 55.

[0051] The spraying mechanism includes: a liquid storage tank 51 connected to the inside of the second frame 2 by bolts, which is used to store the cleaning liquid; a filter pipe 52 connected to one side of the liquid storage tank 51; a filter plate 53 clamped on the filter pipe 52, which is used to filter the cleaning liquid passing through the filter pipe 52; a liquid outlet pipe 54 connected between the filter pipe 52 and the three liquid outlet holes 33; a pump 55 installed in the second frame 2, and the liquid suction port of the pump 55 is connected to the inner bottom of the liquid storage tank 51; a liquid inlet pipe 56 connected between the liquid pumping port of the pump 55 and the three liquid inlet holes 31; semi-spraying rings 57 respectively welded to both sides of the bottoms of the three upper scraping wheels 4. The two semi-spraying rings 57 on the same scraping wheel 4 form a complete ring state around the three wire ropes 00. Three independent cavities are formed between the six semi-spraying rings 57 and the three annular grooves formed by the six semi-annular liquid grooves 32.

[0052] A number of spraying holes are formed on each semi-spraying ring 57, which are used to spray and gather the cleaning liquid to form high pressure.

[0053] The coating mechanism includes: four piston seats 61, two of which are connected to the inner bottom of the first frame 1 by bolts, and the other two piston seats 61 are connected to the inner bottom of the second frame 2 by bolts; a bifurcated pipe 62 is connected between the two piston seats 61 on the first frame 1 and the liquid pumping port of the pump 55; piston rods 63 are respectively slidably connected to the four piston seats 61; tension springs 631 are respectively connected between the four piston rods 63 and the four piston seats 61; a rotating pipe 64 is rotatably connected between the two piston rods 63 on the same side, and there are two rotating pipes 64 in total; sponge rollers 65 are respectively arranged on the two rotating pipes 64, and the sponge rollers 65 are used to coat the wire rope 00 with maintenance oil; a connecting rod assembly is arranged between the piston rod 63 and the first frame 1, which is used to move the two sponge rollers 65 in opposite directions synchronously; a trigger assembly is arranged between the first frame 1, the second frame 2 and the rotating pipe 64, which is used to connect the maintenance oil.

[0054] A number of small holes are formed on the surface of the rotating pipe 64, which are used to evenly immerse the maintenance oil into the sponge roller 65.

[0055] The connecting rod assembly includes: a lever 661 rotatably connected to the first frame 1; a pressing block 662 welded to one of the piston rods 63, and the pressing block 662 is slidably connected to the upper part of the lever 661; a pressed rod 663 welded to the other piston rod 63, and the pressed rod 663 is slidably connected to the lower side of the lever 661.

[0056] The triggering component includes: an oil storage tank 671 respectively connected to the first frame 1 and the second frame 2 by bolts, which is used to store maintenance oil. An oil filling port is opened at the upper part of the oil storage tank 671, and the oil filling port of the oil storage tank 671 is communicated with the outside of the first frame 1 and the second frame 2; sleeves 672 respectively communicated with the bottoms of the two oil storage tanks 671; triggering tubes 673 respectively rotatably connected to one side of the two rotating tubes 64, the two triggering tubes 673 are respectively slidably connected to the two sleeves 672, and triggering holes 674 are opened at the ends of the two triggering tubes 673 away from each other. The movement of the triggering holes 674 can communicate with the sleeves 672, so that the sleeves 672 are communicated with the triggering tubes 673.

[0057] Initially, the liquid storage tank 51 is full of cleaning liquid, and at the same time, the oil storage tank 671 is full of maintenance oil. As time goes by, the maintenance oil on the surface of the wire rope 00 is likely to combine with pollutants in the air to form sludge. When the elevator is running, the wire rope 00 moves past the scraping wheel 4. The texture of the wire rope 00 drives the scraping wheel 4 to rotate, and at the same time, the scraping wheel 4 scrapes off the excess maintenance oil or the formed sludge on the surface of the wire rope 00 to keep it properly clean. Of course, part of the maintenance oil and sludge will pass through the gap between the wire rope 00 and the scraping wheel 4 and pass through the scraping wheel 4. Every once in a while, the staff will maintain and service the elevator. During this period, it is necessary to clean and lubricate the wire rope 00 to complete the operation of replacing the maintenance oil. First, the staff controls the wire rope 00 to run from top to bottom based on this device through the traction machine 0. At the same time, the staff starts the pump 55. The pump 55 pumps the cleaning liquid in the liquid storage tank 51 into each semi-circular liquid groove 32 through the liquid inlet pipe 56. The cleaning liquid in the semi-circular liquid groove 32 gathers through the spraying holes of each semi-spraying ring 57 to form a high-pressure spray on the surface of the wire rope 00. While the scraping wheel 4 rotates, it drives the semi-spraying ring 57 to rotate around the wire rope 00, and then flushes the surface of the wire rope 00 along the texture of the wire rope 00 with the high-pressure cleaning liquid, so as to effectively clean the dead corners in the texture of the wire rope 00. At the same time, a negative pressure is formed in the liquid storage tank 51, and the cleaning liquid after cleaning the wire rope 00 is pumped back through the filter pipe 52, the filter plate 53, the liquid outlet pipe 54 and the liquid outlet hole 33 to form a cycle. The cleaning liquid will carry the washed-off impurities through the filter plate 53, and the filter plate 53 will separate these impurities on the surface, thereby filtering the cleaning liquid for subsequent recycling use;The steel wire rope 00 passing through the lower scraping wheel 4 from top to bottom is the part after cleaning. While cleaning the steel wire rope 00, the pump 55 will pump part of the cleaning liquid into two of the piston seats 61 through the bifurcated pipe 62, and then push two of the piston rods 63 to drive one of the rotating pipes 64, the extrusion block 662, and one of the sponge rollers 65 to move towards the steel wire rope 00. The movement of the extrusion block 662 will squeeze the lever 661 to rotate, and the rotation of the lever 661 will drive the pressure-receiving rod 663, the other two piston rods 63, the other rotating pipe 64, and the other sponge roller 65 to move towards the steel wire rope 00. In this way, the cleaning liquid makes the two rotating pipes 64 and the two sponge rollers 65 move towards each other by squeezing two of the piston rods 63. The four tension springs 631 are all stretched. The two sponge rollers 65 move towards each other and squeeze the steel wire rope 00 to deform and wrap around the surface of the steel wire rope 00. The movement of the rotating pipe 64 drives the trigger pipe 673 to move. After the trigger hole 674 moves, it communicates with the sleeve 672. The maintenance oil in the oil storage tank 671 will sequentially pass through the sleeve 672, the trigger hole 674, and the trigger pipe 673 and enter the rotating pipe 64 under the action of gravity. The maintenance oil in the rotating pipe 64 will evenly penetrate into the sponge roller 65 through several small holes on the rotating pipe 64. The sponge roller 65 will coat the maintenance oil inside on the surface of the moving steel wire rope 00, and then immediately lubricate the surface of the cleaned steel wire rope 00 to improve efficiency. After the cleaning and lubrication are completed, the staff turns off the pump 55. The tension spring 631 resets and drives the piston rod 63 to reset. The reset of the piston rod 63 will push the cleaning liquid in the piston seat 61 back into the bifurcated pipe 62. The sponge roller 65 is separated from the steel wire rope 00. At the same time, the trigger pipe 673 resets and disconnects from the sleeve 672. Subsequently, the staff can remove the filter plate 53 from the filter pipe 52 for replacement.;

[0058] Embodiment 2: On the basis of Embodiment 1, as Figure 6 and Figures 5-19 shown, it further includes a brushing mechanism for brushing off stubborn stains on the surface of the steel wire rope 00, which is arranged between the combined frame 3 and the semi-spraying ring 57. The brushing mechanism includes: semi-extrusion rings 71 respectively welded to the bottoms of the six semi-spraying rings 57. The two semi-extrusion rings 71 on the same scraping wheel 4 form a complete ring state around the three steel wire ropes 00. Each semi-extrusion ring 71 is provided with a wave groove 711, and the wave grooves 711 on the two semi-extrusion rings 71 in contact with each other are connected to form a closed loop; three brush plates 72 respectively slidably connected to the two chute grooves 34. The tops of the six brush plates 72 are respectively located in the six wave grooves 711. The inside of the brush plate 72 is provided with a cavity, and one side of the brush plate 72 is provided with an air inlet; five brush heads 73 respectively slidably connected to each brush plate 72. The wire brushes of the brush heads 73 are in contact with the surface of the steel wire rope 00, and the brush heads 73 are used for brushing the surface of the steel wire rope 00.

[0059] While cleaning the wire rope 00, the rotation of the semi-spraying ring 57 drives the rotation of the semi-extrusion ring 71. The wave groove 711 squeezes the top of the brush plate 72, causing the brush plate 72 to drive the brush head 73 to reciprocate up and down. The brush head 73 repeatedly brushes off the stubborn stains on the surface of the wire rope 00. At the same time, the cleaning liquid flushes off the stains brushed off by the brush head 73, thereby making the cleaning of the surface of the wire rope 00 more thorough and significantly enhancing the cleaning effect on the wire rope 00.

[0060] Example 3: On the basis of Example 2, as Figures 2-6 and Figures 15-19 shown, it further includes an adjustment mechanism for adjusting the brushing force, which is arranged between the combined frame 3, the first frame 1 and the second frame 2. The adjustment mechanism includes: pressure pipes 81 welded respectively inside the two combined frames 3, and the inflation ports of the three brush plates 72 on the same side are slidably communicated with the pressure pipes 81 on the same side; threaded shafts 82 respectively connected by threads to the first frame 1 and the second frame 2, and one ends of the two threaded shafts 82 are respectively slidably connected to one ends of the two pressure pipes 81; piston plates 83 respectively connected to the two threaded shafts 82 by bolts, and the two piston plates 83 are respectively in close contact with the inner walls of the two pressure pipes 81. The piston plates 83 are used to press the air inside the pressure pipes 81 into the brush plates 72.

[0061] Since the temperature and humidity are different due to weather changes during the period between each maintenance, after the cumulative effect of several days, the adhesion strength and quantity of the stains on the surface of the wire rope 00 are different during each maintenance. Before starting the pump 55, the staff can control the wire rope 00 to move downward by a certain distance through the traction machine 0, and observe the brushing-off situation of the stubborn stains on the surface of the wire rope 00. If the stubborn stains are difficult to brush off, the staff can turn the screwing ends of the two threaded shafts 82. The rotation of the threaded shafts 82 will move towards the combined frame 3 through the first frame 1 and the second frame 2. Under the action of the closed cavity formed between the pressure pipes 81, the brush plates 72 and the brush heads 73, the threaded shafts 82 will drive the piston plates 83 to squeeze the air in the closed cavity, and then squeeze the brush heads 73 to move towards the wire rope 00 to apply pressure to the surface of the wire rope 00, improving the brushing force. In this way, the staff can adjust the brushing force according to the adhesion situation of the stubborn stains on the surface of the wire rope 00, thereby making the cleaning of the wire rope 00 more thorough while ensuring the service life of the brush heads 73, and further enhancing the cleaning effect. After the cleaning is completed, the staff can turn back the two threaded shafts 82.

[0062] Those skilled in the art of this industry should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
