Description

Technical Field

[0001] The present invention relates to a cable hoisting system, and particularly to a steel cable maintenance device, system and maintenance method. Background Art

[0002] In cable hoisting projects, there are many types and large quantities of steel ropes used. After the project is completed, the used steel ropes need to be stored. Since the steel cables are in an environment with a large amount of dust and moisture during use, attachments are likely to form on the steel cables. These attachments will not only adsorb the lubricating oil on the steel cables, resulting in an increase in the friction between the steel wires, but also cause continuous corrosion of the steel cables, leading to rust.

[0003] When the stored steel cables are reused, generally only simple inspections are carried out or no inspections are carried out. This causes the steel cables, when reused, due to the erosion and adsorption of the attachments, not only increases the friction between the steel wires, shortening their service life, but also causes the mechanical properties of the steel cables to deteriorate due to erosion, resulting in brittle fractures, presenting major safety hazards. Summary of the Invention

[0044] As Figure 1-7 shown, an embodiment of the present invention provides a steel - cable maintenance device, including an oil - immersion basin 100 and a slag - removing unit 200. The oil - immersion basin 100 includes a basin body 110 and a heater 120 arranged below the basin body 110. The upper end of the basin body 110 is open and used to hold grease. The heater 120 heats the grease in the basin body 110 below, so that the grease is always in a molten state. A plurality of rollers are arranged in the length direction of the basin body 110. The rollers include supporting rollers 130 and pressing rollers 140. There are at least two pressing rollers 140 arranged in the length direction of the basin body 110. The supporting rollers 130 are also arranged along the length direction of the basin body 110. There is at least one supporting roller 130. A plurality of supporting rollers 130 are arranged between a plurality of pressing rollers 140. The rotation axes of the supporting rollers 130 and the pressing rollers 140 are perpendicular to the length direction of the basin body 110.

[0045] Taking two pressing rollers 140 and four supporting rollers 130 as an example, two of the supporting rollers 130 are arranged along the length direction of the basin body 110 on one side of the basin body 110, and the other two supporting rollers 130 are arranged along the length direction of the basin body 110 on the other side of the basin body 110. The two pressing rollers 140 are arranged between the two supporting rollers 130 with the closest distance on both sides.

[0046] Preferably, the supporting rollers 130 are installed on the basin body 110 through supporting roller seats.

[0047] In this application, the idler 130 is used to lift the steel cable 300, and the pressure roller 140 is used to press the steel cable 300 lifted by the idler 130 into the grease, so that the steel cable 300 is immersed in the grease during the forward movement.

[0048] In this application, the grease is cleaning grease or protective grease.

[0049] Along the length direction of the basin body 110, two slag removal units 200 are also provided. The two slag removal units 200 are located on the outermost sides of the idler 130, and the two slag removal units 200 are cleaning the steel cable 300.

[0050] On the upper end of the heater 120, an outward turning edge 111 is also provided in the length direction, and the aforementioned slag removal unit 200 is provided on the outward turning edge 111. Preferably, a reinforcing rod is also provided between the outward turning edge 111 and the heater 120 to prevent the outward turning edge 111 from being bent due to bearing the slag removal unit 200.

[0051] Each slag removal unit 200 includes an upper moving plate 210 and two lower moving plates 220. Among them, the two lower moving plates 220 are arranged below the lower moving plate 220 along the length direction of the basin body 110. A V-shaped base 230 is provided on the upper surface of each of the two lower moving plates 220, and a brush is provided on the V-shaped base 230. Another V-shaped base 230 is also provided on the lower surface of the upper moving plate 210, and the other V-shaped base 230 is located at the center of the connection line of the two lower V-shaped bases 230 below. When the steel cable 300 passes through the slag removal unit 200, it passes through the lower V-shaped base 230, the upper V-shaped base 230, and the lower V-shaped base 230 in sequence, so as to comprehensively clean the steel cable 300.

[0052] Furthermore, the slag removal unit 200 further includes two pairs of vertical screws 240. Each pair of vertical screws 240 has two. Each pair of vertical screws 240 is arranged along the width direction of the basin body 110, and the two pairs of vertical screws 240 are arranged along the length direction of the basin body 110, that is, the four vertical screws 240 are arranged in an array. A first spring 250 is sleeved outside each vertical screw 240. The upper moving plate 210 passes through each vertical screw 240 and is slidably connected with the vertical screw 240. The lower end of the upper moving plate 210 also abuts against the upper end of the first spring 250. A nut 260 is also screwed on each vertical bolt, and the nut 260 is located above the upper moving plate 210. By adjusting the position of the nut 260 on the vertical screw 240, the upper limit position of the upper moving plate 210 on the vertical screw 240 when being pushed by the first spring 250 is ensured.

[0053] A second spring 270 is further provided between the lower moving plate 220 and the outer flange 111. One end of the second spring 270 is connected to the lower moving plate 220, and the other end is connected to the outer flange 111. The second springs 270 on each lower moving plate 220 are arranged in a rectangular array.

[0054] Since the upper and lower V-shaped bases 230 are movable in the vertical direction, the steel cables 300 of different diameters can be cleaned.

[0055] In the present application, in order to facilitate the installation of the lower wheel, the basin body 110 is rectangular in shape as a whole, and a crossbeam 150 is provided in the middle of the basin body 110 along the width direction of the basin body 110. A lifting seat 160 is provided on the crossbeam 150, and two lifting rods 161 are screwed in the lifting seat 160. A roller seat is provided at the lower end of the two lifting rods 161. The roller seat is rotatably connected to the lifting rod 161, and the aforementioned plurality of rollers 140 are rotatably provided on the roller seat. The roller 140 can be raised and lowered under the action of the lifting rod 161, which can not only make the steel cable 300 immersed in grease at different liquid levels, but also can make the steel cable 300 enter the grease for a longer length by pressing the steel cable 300 downward, so as to ensure that the steel cable 300 is immersed in the grease for a longer time when passing through the grease, which is more conducive to the softening of the attachment by the grease or the infiltration of the grease into the internal property protective film of the steel cable 300.

[0056] A turnbuckle bolt 170 is also provided between the lifting seat 160 and the slag removal unit 200, one end of the turnbuckle bolt 170 is hinged to the lifting seat 160, and the other end is hinged to the upper movable plate 210 of the slag removal unit 200. One end of the turnbuckle bolt 170 can also be hinged to the lifting seat 160 or the slag removal unit 200 through a hinged extension arm.

[0057] The heater 120 also has an opening at the top, and the opening of the heater 120 is used to accommodate the basin 110, so that the basin 110 can be placed on the heater 120 from the opening of the heater 120. A separation plate 123 is arranged in the heater 120, and the separation plate 123 includes a frame and a plurality of furnace bridges, and the plurality of furnace bridges are arranged on the frame at intervals. The separation plate 123 divides the heater 120 into a combustion area 121 and an ash falling area 122 in the vertical direction. The combustion area 121 is used to generate an open flame to melt the grease, and a retractable ash falling basin is arranged in the ash falling area 122, and the ash falling basin is used to receive the ash after the fuel is burned.

[0058] Preferably, a support leg 180 is provided at the bottom of the heating part, a concrete base is provided below the support leg 180, and the support leg 180 and the concrete base are detachably connected by expansion bolts. The connection between the concrete base and the support leg 180 can ensure that the maintenance device 400 resists the horizontal thrust when the steel cable 300 is running.

[0059] Preferably, a discharge port is further provided on the side of the outer flanging 111 close to the heater 120, and a slag discharge channel 190 is provided below the outer flanging 111. The slag discharge channel 190 is located below the discharge port.

[0060] As Figure 8 , the present application further provides a maintenance system, including at least two maintenance devices 400. A plurality of maintenance devices 400 are arranged along the length direction of the maintenance device 400 for the steel cable 300 to pass through in sequence. The basin body 110 of the last maintenance device 400 located downstream contains protective grease, and the other maintenance devices 400 contain cleaning grease.

[0061] Preferably, the distance between two maintenance devices 400 is 1-3 m. The cleaning grease can be pure oil without impurities and non-flammable, such as diesel oil. The protective grease can be special grease for steel ropes and diluent oil.

[0062] In this maintenance system, the starting end of the steel cable 300 can be connected to a steel cable collecting device 500 (such as a winch) after passing through a plurality of maintenance devices 400 in sequence. Both ends of the steel cable 300 in each maintenance device 400 are supported by the idler rollers 130, and the middle part is pressed down into the grease by the pressure rollers 140. When the steel cable 300 passes through the first maintenance device 400 upstream, the slag removal unit 200 located upstream of the maintenance device 400 performs preliminary cleaning on the steel cable 300. This preliminary cleaning mainly removes the attachments on the surface of the steel cable 300, and the attachments enter the slag discharge channel. After preliminary cleaning, the steel cable 300 is immersed in the cleaning grease, and the cleaning grease wets the stubborn attachments on the upper end of the steel cable 300 to soften them. When the steel cable 300 passes through the slag removal unit 200 downstream of the first maintenance device 400, the softened attachments are brushed off. In order to ensure that the attachments on the steel cable 300 are minimized as much as possible, several more maintenance devices 400 can be appropriately added. When the steel cable 300 moves to the last maintenance device 400, the slag removal unit 200 located upstream of this maintenance device 400 brushes off the attachments on the steel cable 300 and cleans the cleaning grease attached to the steel cable 300. After being wetted by the protective grease, the steel cable 300 is coated, and a uniform protective film is formed on the steel cable 300. After coating, the steel cable 300 passes through the downstream slag removal unit 200 to wipe off the excess protective grease and then winds around the steel cable collecting device 500.

[0063] In the present application, a maintenance method is also provided. Using the aforementioned maintenance system, it includes the following steps:

[0064] S1. Pass the starting end of the steel cable 300 through each maintenance device 400 in sequence, and ensure that the idler rollers 130 in each maintenance device 400 support both ends of the steel cable 300 passing through the corresponding maintenance device 400, and the pressure rollers 140 press the middle part of the steel cable 300 into the grease.

[0065] S2. Heat the grease in the basin body 110 to melt the cleaning grease or the protective grease;

[0066] S3. Pull the starting end of the steel cable 300 to make the steel cable 300 pass through each maintenance device 400 in turn and complete the maintenance.

[0067] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art of the present technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
