Description

TECHNICAL FIELD

[0001] The present application relates to a cleaning device, in particular to an automatic cleaning device and method for a positioning anchor wire rope. BACKGROUND

[0002] The positioning anchor of a large floating offshore crane is usually connected by a wire rope. The crane is used for a long time during construction, and the positioning anchor wire rope is soaked in seawater and silt for a long time. When the anchor is retracted, a large amount of silt, seawater and other sundries will be attached to the gaps of the wire rope, which brings great difficulty to the subsequent maintenance work, and causes corrosion to the wire rope and its guiding device, reel and other devices. In order to facilitate the later maintenance and improve the service life of the wire rope, the surface attachments of the wire rope need to be flushed when the anchor is retracted. At present, manual flushing of the wire rope by a spray gun is usually adopted, which requires two crew members to stand on both sides of the wire rope for continuous flushing, and the flushing effect is poor and the labor intensity is large. SUMMARY

[0003] The technical problem to be solved by the present application is to provide an automatic cleaning device and method for a positioning anchor wire rope, which can clean the positioning anchor wire rope comprehensively and efficiently, and greatly reduce the labor intensity.

[0004] To solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0005] An automatic cleaning device for a positioning anchor wire rope, comprising a fixing mechanism and a flushing mechanism.

[0006] The fixing mechanism comprises an annular connecting plate fixed on the outer drum of a universal fairlead. A limiting plate is fixed on one end of the annular connecting plate. The limiting plate is connected with the flushing mechanism through a first connecting rod.

[0007] The flushing mechanism comprises two flushing mechanisms and a brushing mechanism. The two flushing mechanisms are arranged at intervals and connected through a second connecting rod. The brushing mechanism is arranged between the two flushing mechanisms.

[0008] The flushing mechanism comprises a circular-arc-shaped water pipe. The upper end of the circular-arc-shaped water pipe is communicated with a water inlet, and a plurality of water outlets are arranged on the inner wall.

[0009] The brushing mechanism comprises a tension spring. One end of the tension spring is installed on the second connecting rod, and the other end of the tension spring is detachably connected with a brush head box. The brush head box is internally provided with a brush head through which the positioning anchor wire rope can pass.

[0010] A sewage collecting mechanism is arranged outside the flushing mechanism. The sewage collecting mechanism comprises a waterproof cover. The bottom of the waterproof cover is provided with an opening. The upper end of the sewage collecting mechanism is slidably matched with the opening of the waterproof cover through a wing plate.

[0011] The water baffle is fixed to the end of the annular connecting plate, the outer diameter of the water baffle is consistent with the outer diameter of the outer roller of the universal fairlead, and the inner diameter of the water baffle is smaller than the size of the gap between the rolling shaft and the outer roller of the universal fairlead and larger than the size of the positioning anchor steel wire rope.

[0012] The water inlet is located at the middle part of the circular arc-shaped water pipe and is provided with a 60-degree elbow between the circular arc-shaped water pipe.

[0013] The brush head box comprises an upper brush head box and a lower brush head box, the upper brush head box and the lower brush head box are spliced and detachably connected through a latch.

[0014] The first connecting rod is a fork rod assembly, one end of the fork rod assembly is connected with the limiting plate, and the other end is connected with the circular arc-shaped water pipe; the two circular arc-shaped water pipes are reinforced through the fork rod assembly.

[0015] The lower part of the fixing mechanism and the flushing mechanism adopts an open structure.

[0016] The surface of the fixing mechanism and the flushing mechanism is subjected to galvanizing treatment.

[0017] The positioning anchor steel wire rope automatic cleaning device and method have the following technical effects:

[0018] 1) By sequentially arranging two circular arc-shaped water pipes and a brushing mechanism along the length direction, the brushing mechanism is arranged between the two circular arc-shaped water pipes, so that the cleaning procedure of flushing-brushing-flushing is realized, the steel wire rope is first flushed by the circular arc-shaped water pipes to remove most of the silt on the surface of the positioning anchor steel wire rope, then the steel wire rope passes through the brushing mechanism to remove the adhering matters in the gap of the steel wire rope, and finally the steel wire rope is flushed again by the circular arc-shaped water pipes to completely remove the residual matters on the surface and in the gap. In this way, the problem of poor cleaning effect of the steel wire rope by the handheld spray gun is solved. Moreover, the device is installed on the universal fairlead, and the steel wire rope is brushed throughout the whole process when the anchor is collected, until the anchor collection is completed, so that the labor intensity can be greatly reduced, and the service life of the positioning anchor steel wire rope can be effectively improved.

[0019] 2) The bottom of the device is provided in an open type, which can facilitate the installation and dismounting of the positioning anchor steel wire rope automatic cleaning mechanism, facilitate the replacement of the brush head in the subsequent brushing mechanism, and avoid blockage caused by too much silt during flushing, so as to affect the cleaning effect.

[0020] 3) By arranging four water outlets on the circular arc-shaped water pipe, the water outlet angles of the adjacent two water outlets are perpendicular to each other, and the water outlet angle of each water outlet is 45 degrees with the vertical direction, so that the water flow can cover each angle of the steel wire rope and flush the steel wire rope in the circumferential direction. In this way, the problem of single flushing angle is solved.

[0021] 4), by setting the annular brush head, the inner diameter of the brush head is smaller than the diameter of the steel wire rope, so that the brush head can be easily placed in the steel wire rope gap; by designing a detachable brush head box, the brush head box and the brush head can be closely matched, and the brush head can be easily replaced.

[0022] 5), because the steel wire rope will have a certain degree of shaking when collecting the steel wire rope, by using four tension springs to connect the brush washing mechanism (flexible connection and fixation), the shaking of the steel wire rope can be avoided, and the whole washing mechanism can be avoided from shaking, thereby avoiding the compression damage of the parts of the equipment during the shaking process; and the four tension springs can be detached, which is convenient for the early placement of the steel wire rope in the brush washing mechanism.

[0023] 6), two circular arc-shaped water pipes 4 are provided with independent water inlets, which can ensure that the outlet has sufficient flow and pressure to remove silt and other impurities; at the same time, a 60° elbow is arranged at the water inlet position, which can reduce the moment and avoid the bending of the water supply pipe.

[0024] 7), by using a waterproof cover, the splashing of sewage can be avoided, and the problem of sewage pollution of the deck during the flushing process can be solved; at the same time, the bottom of the waterproof cover is cut off, that is, along the part directly below the steel wire rope, so that the opening angle is between 65°-70°, which can ensure that the sewage is smoothly discharged, and the problem of blockage of silt and other impurities after cleaning can be solved.

[0025] 8), according to the size of the outer roller of the universal cable guide, a fixing mechanism matched with the outer roller is designed, which is connected by screws, and the outer roller of the universal cable guide is fixed with its base, which can provide stable support for the steel wire rope cleaning mechanism.

[0026] 9), by setting an annular waterproof plate, the outer diameter of the annular waterproof plate is consistent with the outer diameter of the roller, and the inner diameter is smaller than the size of the gap between the roller shaft and the roller of the universal cable guide and larger than the size of the steel wire rope. The problem of corrosion of the roller caused by the splashing of sewage into the roller after flushing can be solved. BRIEF DESCRIPTION OF DRAWINGS

[0033] As shown in the figure, an automatic cleaning device for positioning anchor wire rope includes a fixing mechanism, a flushing mechanism, and a sewage collection mechanism. The fixing mechanism is used to fix the device on the outer drum of the universal fairlead, and the flushing mechanism realizes flushing as the universal fairlead moves with the traction of the positioning anchor wire rope. The sewage after flushing is collected and discharged by the sewage collection mechanism. Figure 1 As shown in the figure, the fixing mechanism includes an annular connecting plate 18, the inner diameter of which is consistent with the outer diameter of the universal fairlead. The annular connecting plate 18 is provided with screw fixing holes, and can be fixed on the outer drum of the universal fairlead through the screws.

[0034] Figure 2 Preferably, the end inner wall of the annular connecting plate 18 is welded with a limiting plate 19, and the inner side of the limiting plate 19 is provided with a water baffle 20. The outer diameter of the water baffle 20 is consistent with the outer diameter of the outer drum of the universal fairlead, and the inner diameter of the water baffle 20 is smaller than the size of the gap between the rolling shaft and the drum of the universal fairlead and larger than the size of the wire rope. The water baffle 20 can prevent the sewage after flushing from splashing into the rolling shaft of the universal fairlead, thereby prolonging the service life.

[0035] The fixing mechanism and the flushing mechanism are connected through a first connecting rod.

[0036] Preferably, the first connecting rod is composed of angle steel one 21, angle steel two 22, and angle steel three 23. The angle steel two 22 and the angle steel three 23 are cross-welded into a fork rod assembly, one end of which is fixed on the limiting plate 19, and the other end is fixed and welded on the base 17 of the flushing mechanism. The fork rod assembly is bilaterally symmetrical. The angle steel one 21 is also bilaterally distributed at the lower end edges of the fixing mechanism and the flushing mechanism, one end of which is fixed on the limiting plate 19, and the other end is fixed on the base 17 of the flushing mechanism. Through cross-welding, the torsional resistance and the connection strength are both increased.

[0037] As shown in the figure, the flushing mechanism includes two flushing mechanisms and a brushing mechanism. The two flushing mechanisms are a certain distance apart, and the brushing mechanism is arranged between the two flushing mechanisms to realize the cleaning procedure of flushing-brushing-flushing. The wire rope first passes through the flushing mechanism to remove most of the silt on the surface of the positioning anchor wire rope, then passes through the brushing mechanism to remove the attachments in the gap of the wire rope, and finally passes through the flushing mechanism again to completely remove the remaining substances on the surface and in the gap.

[0038] As shown in the figure, the flushing mechanism includes two flushing mechanisms and a brushing mechanism. The two flushing mechanisms are a certain distance apart, and the brushing mechanism is arranged between the two flushing mechanisms to realize the cleaning procedure of flushing-brushing-flushing. The wire rope first passes through the flushing mechanism to remove most of the silt on the surface of the positioning anchor wire rope, then passes through the brushing mechanism to remove the attachments in the gap of the wire rope, and finally passes through the flushing mechanism again to completely remove the remaining substances on the surface and in the gap. Figure 2 As shown in the figure, the flushing mechanism includes two flushing mechanisms and a brushing mechanism. The two flushing mechanisms are a certain distance apart, and the brushing mechanism is arranged between the two flushing mechanisms to realize the cleaning procedure of flushing-brushing-flushing. The wire rope first passes through the flushing mechanism to remove most of the silt on the surface of the positioning anchor wire rope, then passes through the brushing mechanism to remove the attachments in the gap of the wire rope, and finally passes through the flushing mechanism again to completely remove the remaining substances on the surface and in the gap.

[0039] Figure 2 ​​As shown, each flushing mechanism includes an arc-shaped water pipe 4, which has an inlet 1 and an outlet 5. The arc-shaped water pipe 4 between the two flushing mechanisms is welded and fixed together by four second connecting rods 7 (angle steel).

[0040] like Figure 2 As shown, the scrubbing mechanism includes four third connecting rods 8, each pointing parallel to the outlet 5. One end of each third connecting rod 8 is welded to the second connecting rod 7, and the other end is connected to a tension spring 9. The other ends of the four tension springs 9 are detachably hooked to the connecting rings on the brush head box, which makes it easy to remove one side of the tension spring 9 and facilitates the entry of the positioning anchor wire rope.

[0041] like Figure 3 As shown, the brush head box is divided into an upper brush head box 16 and a lower brush head box 12. Pin sleeves are provided on both ends of the joint between the upper brush head box 16 and the lower brush head box 12. A first pin sleeve 13 is located on the lower brush head box 12, and a second pin sleeve 15 is located on the upper brush head box 16. The first pin sleeve 13 and the second pin sleeve 15 are aligned and their pin holes are concentric, and are fixed by inserting a pin 14. This pin-and-pin-hole connection method not only facilitates the replacement of the brush head 28 (composed of two semicircles) and the entry of the positioning anchor wire rope, but also ensures connection strength, thereby improving brushing efficiency.

[0042] like Figure 4 As shown, preferably, the number of water outlets 5 is four, the water outlet angles of two adjacent water outlets 5 are perpendicular to each other, and the water outlet angle of each water outlet 5 is at a 45° angle to the vertical direction, ensuring that the water flow can cover every angle of the steel wire rope.

[0043] like Figure 4 As shown, preferably, a 60° elbow is set at the water inlet 1 position. This reduces the torque by decreasing the distance from the water inlet to the axis, and also avoids bending of the water supply pipe.

[0044] Preferably, two connecting plates 10 (steel plates) welded diagonally are added between the two adjacent second connecting rods 7 between the two arc-shaped water pipes 4. The stability is increased by welding the steel plates, thereby increasing the torsional resistance of the structure (there is a certain distance between the two arc-shaped water pipes 4. If they are only connected by four angle steels, after the water pipes are connected and water is supplied, the two arc-shaped water pipes 4 that are far away from the universal cable guide will generate a certain torque due to the connection of the water pipes, and the device will tend to rotate in the circumferential direction).

[0045] Preferably, connecting blocks 11 are welded to the outside of the two arc-shaped water pipes 4 and located on the second connecting rod 7. Each second connecting rod 7 is provided with two connecting blocks 11, and the connecting blocks 11 are welded and fixed to the waterproof cover 24. By setting the waterproof cover, the splashing of sewage can be avoided, and the sewage can be prevented from contaminating the deck during the rinsing process.

[0046] Preferably, the bottom of the waterproof cover 24 is along the part directly below the positioning anchor steel wire rope, so that the opening angle is between 65°-70°, ensuring that the sewage (containing silt and other debris) is smoothly guided out, while also facilitating the positioning anchor steel wire rope to be introduced from below.

[0047] As shown in Figure 1 , Figure 5 Preferably, a sewage collection mechanism 25 is installed at the bottom of the waterproof cover, the sewage collection mechanism 25 is downwardly conical and funnel-shaped as a whole, the width at the top is matched with the opening width at the bottom of the waterproof cover 24, and the front-to-back length is slightly larger than the length of the waterproof cover 24. A pair of wing plates 26 are arranged at both sides of the top of the sewage collection mechanism 25, the wing plates 26 are circularly arc-shaped in the axial direction and are matched with the bottom of the waterproof cover 24, forming an axially pullable sewage collection mechanism. The collected sewage is discharged to the sea through the bottom.

[0048] Preferably, in order to solve the problems of positioning anchor steel wire rope assembly and subsequent maintenance, the bottom of the device is open. Specifically:

[0049] The bottom of the circular arc-shaped water pipe 4 is symmetrically cut on both sides, so that the angles between the two cut extension lines and the vertical direction are both between 33°-35°. After cutting, the cut part of the circular arc-shaped water pipe is sealed and welded with a blind plate 6. Similarly, the fixing mechanism including the annular waterproof plate is symmetrically cut on both sides, and the angles between the two cut extension lines and the vertical direction are both between 33°-35°.

[0050] Preferably, the surface of the device is galvanized to improve the corrosion resistance to seawater.

[0051] Working principle and process:

[0052] 1) When anchoring, the steel wire rope is in the brush head box of the device, and the device is fixed to the outer roller of the universal fairlead, which does not affect the anchoring operation and does not need to be removed. However, in order to prolong the service life of the brush head, the brush head can be removed through the detachable brush head box during anchoring, and the brush head 28 can be installed again during the recovery operation.

[0053] 2) When performing the recovery operation, the device is prepared, the two semicircular brush heads are installed in the brush head box, and the water pipe is connected to the water inlet 1 of the device. When the positioning anchor is lifted and recovered, the steel wire rope passes through the device at a certain speed. At this time, the water pipe is supplied with water, the steel wire rope first passes through the circular arc-shaped water pipe for washing, removing most of the silt on the surface of the positioning anchor steel wire rope, then passes through the brushing mechanism to remove the adhering objects in the gaps of the steel wire rope, and finally passes through the circular arc-shaped water pipe again for thorough removal of the remaining objects on the surface and in the gaps.
