Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1-5 A wire rope winding device for marine port cranes includes a winch frame 1. The winch frame 1 is characterized by having a helical screw 7 and a movable rod 8 mounted on it via two first fixed columns 6. A first sleeve 9, movable left and right, is mounted on the helical screw 7. A second sleeve 91 is slidably connected to the movable rod 8. A traction device is installed between the first sleeve 9 and the second sleeve 91. A ring-shaped airbag 94 is mounted on the second sleeve 91. One end of the ring-shaped airbag 94, facing away from the traction device, is fixedly connected to the first fixed column 6. A first one-way air valve 942 is provided on the ring-shaped airbag 94, through which gas enters the ring-shaped airbag 94. A stacked, ring-shaped air pipe 941 is connected to the ring-shaped airbag 94. An oil outlet 95 is provided at the bottom of the traction device, and a pressurization chamber 947 is provided inside the traction device. A second spring 945 is fixedly connected to the inner wall of the pressurization chamber 947. A piston push plate 946 is connected to the bottom end of the second spring. The piston push plate 946 is in close contact with the pressurization chamber 947, and a limiting block is installed on the pressurization chamber 947 to limit the maximum displacement distance of the piston push plate 946. One end of the air pipe 941 is connected to the inside of the pressurization chamber 947 through a second one-way air valve 943. The pressure inside the pressurization chamber 947 increases, and the piston push plate 946 is thus pushed.

[0027] Reference Figure 6A drive motor 3 is mounted on the winch frame 1, and a rotating shaft 31 is mounted on the drive motor 3. The rotating shaft 31 is connected to a first gear 5 through the winch frame 1. A first auxiliary gear 52, which is symmetrically arranged, is fixedly connected to the screw 7. The first auxiliary gear 52 is adapted to the first gear 5. A second fixed column 62 is fixedly connected to the winch frame 1, and a second auxiliary gear 53 is rotatably connected to the second fixed column 62. The second auxiliary gear 53 has the same number of teeth and tooth pitch as the first gear 5, and plays the role of reversing the gear direction. The first auxiliary gear 52 can directly drive the screw 7 to rotate, thereby driving the traction device to move left and right.

[0028] The traction device is equipped with a second traction pipe 92, and the second traction pipe 92 is provided with an anti-slip groove 921. The anti-slip groove 921 can scrape off excess lubricating oil from the surface of the wire rope and prevent the wire rope from rotating in the traction device.

[0029] The traction device is equipped with a pressure relief box 93, which contains a first magnetic block 932. A second magnetic block 933 is symmetrically arranged on both sides of the oil outlet 95. The second magnetic block 933 and the first magnetic block 932 are magnetically repelled. When the traction device moves left and right, the first magnetic block 932 moves accordingly. When it moves to the left and right side walls of the pressure relief box 93, it acts on the second magnetic block 932, generating a magnetic field that repels the lubricating oil adhering to the inner wall of the traction device, thus preventing the lubricating oil from accumulating and affecting the oil delivery effect.

[0030] A third one-way valve 944 is installed on the inner wall of the pressurization chamber 947. The third one-way valve 944 is located away from the second one-way valve 943 and close to the piston push plate 946. When the piston push plate 946 reaches its maximum position, the third one-way valve 944 is exposed, and the gas in the pressurization chamber enters the third one-way valve. The third one-way valve 944 is connected to the inside of the pressure relief box 93 through the air outlet channel 948. A pressure relief pipe 931 is installed on the pressure relief box 93. The pressure relief pipe 931 is set in the shape of a thin tube, and an air nozzle 932 is fixedly connected to the end away from the pressure relief box 93. The air nozzle 932 is set in the shape of a flat box.

[0031] A winch wheel 2 is fixedly connected to the shaft 31. The winch wheel 2 has multiple through holes 21, which can drain excess oil from the wire rope and increase the contact area with air for heat dissipation. An oil storage tank 4 for collecting and storing oil is installed below the winch wheel 2 via a winch frame 1. An oil filter plate 41 is installed on the oil storage tank 4. The oil filter plate 41 can filter the oil flowing out from the traction pipe. A collection groove 411 for collecting impurities left by the wire rope after passing through the traction pipe is opened on the side of the oil filter plate 41 near the winch wheel 2. An air nozzle 932 is inclinedly set on the oil filter plate 41 to blow the oil accumulated on the oil filter plate 41 into the oil storage tank 4.

[0032] A pump chamber 42 is installed inside the oil storage tank 4. The pump chamber 42 includes an end face 45 and an outer surface. The end face 45 is arc-shaped and fits against the first gear 5. A rubber sealing ring is installed on the outer surface. A pressure oil port 43 is opened on the bottom surface of the pump chamber 42 near the oil storage tank 4. A pressure oil pipe 44 is fixedly connected to the pump chamber 42. Due to the oil pressure in the oil storage tank 4, oil always enters through the pressure oil port 43. Through the rotation of the first gear 5, the pressure in the upper part of the pump chamber 42 decreases, and the lower part of the oil is sucked into the pressure oil pipe 44.

[0033] The screw 7 has a hollow internal structure. The end of the pressure oil pipe 44 away from the pump chamber 42 is connected to the inside of the screw 7. The pressure oil pipe 44 introduces oil. As the screw 7 rotates, the lubricating oil rolls inside and is agitated with the oil filter column 71 to prevent the oil from solidifying. The oil filter column 71 is fixedly connected to the pressure oil pipe 44. The oil filter column 71 has multiple oil filter holes. The capillary hose 72 is fixedly connected to the oil filter column 71. The capillary hose 72 is wound in a ring around the screw 7, with one end connected to the oil filter hole and the other end fixedly connected to the oil inlet 73, which leads to the inside of the traction device.

[0034] The lower end of the oil outlet 95 is equipped with a first traction pipe 97. The oil outlet 95 flushes the wire rope so that the oil completely covers the wire rope. An oil box 96 for lubricating the two sides of the wire rope is fixedly connected to the first traction pipe 97. The oil box 96 can lubricate the sides of the wire rope. The first traction pipe 97 is provided with a rope immersion groove 98 for soaking the bottom of the wire rope.

[0035] The movable rod 8 is fixedly connected to the groove opened on the first fixed post 6 by the first spring 61, and can be used to adjust the vertical position of the traction device.

[0036] Working principle: The wire rope is passed through the traction device and fixed to the winch pulley. The wire rope passes through the first traction pipe 97 and the second traction pipe 92 respectively. The drive motor 3 is started, and the winch pulley 2 begins to roll clockwise, winding the wire rope around it. The first gear 5 rotates accordingly, driving the first auxiliary gear 52. The traction device begins to move to the left along the spiral screw 7. The traction wire rope is wound around the winch pulley 2 at fixed intervals. When the traction device reaches the leftmost end, the second gear 51, in conjunction with the second auxiliary gear 53, drives the first auxiliary gear 52 to rotate counterclockwise, thus moving the traction device to the right. During this process, the reciprocating motion of the traction device compresses the ring-shaped air bladder 94 installed on the moving rod 7. Gas enters the traction device, pressurizing and spraying oil at the oil outlet. The wire rope is thus evenly coated with oil. Excess oil is collected in the oil storage tank 4 and then re-enters the traction device through the pump chamber 42.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
