Description

Technical Field

[0001] The utility model relates to the technical field of spraying, and more specifically, to a crane cable coating spraying machine. Background Art

[0002] Lifting cables are different from ordinary cables. They are often used in lifting machinery, such as cranes and hoists, which need to work in extreme environments, such as high temperature, low temperature, humidity, etc., so they have higher requirements for corrosion resistance, strength and flexibility of materials. Lifting cables are usually made of multiple strands of high-strength steel wire to ensure their stability and safety during the lifting process.

[0003] In the production process of lifting steel ropes, spraying lubricating coating is an essential step, because the lubricating coating can effectively reduce the friction between the steel rope and the pulley or drum, increase the service life of the steel rope, and prevent rust on the surface of the steel rope. The quality and uniformity of the lubricating coating have a direct impact on the performance of the lifting steel rope.

[0004] The existing coating equipment uses a spraying method from above and is set at the junction of multiple strands of steel wire that are about to be wound into a steel cable. The steel wire passes through the capstan and rotates continuously under the drive of the capstan, forming a pointed cone in the forward direction. The position of the nozzle remains unchanged during the spraying process, and the lubricating oil covers the surface of the steel wire downward under the action of gravity. Due to the limited angle of spraying the lubricating oil and the steel wire itself playing a diversion role, a lot of lubricating liquid is diverted by the steel wire to the unwound part, while the part of the steel wire inside the steel cable cannot be completely covered by the lubricating oil, causing the steel wires in this part to rub against each other, affecting the service life of the steel cable.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a crane cable coating spraying machine. Utility Model Content

[0009] Preferably, the first gear ring and the second gear ring are both annular structures, are parallel to each other, and the central axis coincides with the central axis of the first capstan.

[0010] Preferably, the gears are arranged in at least two groups distributed along the circumference to ensure the stability of operation between the first gear ring and the second gear ring.

[0011] Preferably, the gear is mounted on a mounting frame via a bearing, the mounting frame is mounted on the surface of a collecting box, and the collecting box is used to recover lubricating oil that slides off the steel wire.

[0015] 1. In the utility model, the lubricating oil is sprayed from the outside to the inside by setting an outer layer nozzle, and the lubricating oil is sprayed from the inner layer of the winding to the outside by setting a spiral nozzle, and the lubricating oil is sprayed evenly inside and outside, which reduces the lubricating oil consumption and ensures that the surface of the steel wire is completely covered with the lubricating oil, thereby solving the problem in the prior art that due to the limited angle of spraying the lubricating oil and the steel wire itself playing a diversion role, a lot of lubricating liquid is diverted by the steel wire to the unwound part, while the part of the steel wire located inside the steel cable cannot be completely covered by the lubricating oil, so that the steel wires in this part rub against each other, which affects the service life of the steel cable;

[0023] like Figure 1-4 As shown, a crane cable coating spraying machine includes a steel wire 3 for producing a steel cable, a first capstan 1 and a second capstan 2, the second capstan 2 is mounted on the first capstan 1 through a plurality of sets of synchronization rods 4, the first capstan 1 is driven by a rotating motor, and the rotation of the first capstan 1 drives the second capstan 2 to rotate at the same angular velocity, except that Figure 1 and 2 As shown, the size of the second capstan 2 is much smaller than that of the first capstan 1. The first capstan 1 and the second capstan 2 are both circumferentially distributed with multiple groups of through holes. After the steel wire 3 passes through the through holes on the first capstan 1, it passes into the through holes on the second capstan 2. Figure 1 and 2 As shown, after the steel wire 3 passes through the second capstan 2 from the first capstan 1, it is gathered and wound by the second capstan 2, and the steel wire 3 is gathered to form a cone shape and is wound into a whole steel cable at the front end of the second capstan 2;

[0024] The first gear ring 5 is also provided on the second capstan 2. The central axis of the first gear ring 5 coincides with the central axis of the first capstan 1. The movement states of the first gear ring 5 and the second capstan 2 are synchronized. The first gear ring 5 and the second capstan 2 maintain the same rotation direction and the same speed for rotational movement. The first gear ring 5 is meshed with a gear 9. The gear 9 is mounted on a mounting frame 11 through a bearing. The first gear ring 5 rotates to drive the gear 9 to rotate in situ. The gear 9 is also meshed with a second gear ring 6. The first gear ring 5 and the second gear ring 6 are both annular structures. The two are parallel to each other, and the central axis of the second gear ring 6 also coincides with the central axis of the first capstan 1. The gear 9 drives the second gear ring 6 to rotate. Figure 2 and 3 As shown, the first gear ring 5 and the second gear ring 6 are respectively on the opposite sides of the gear 9. When the gear 9 rotates in the vertical direction, the vector directions of the motion trajectories on both sides thereof are opposite. For example, when the gear 9 rotates clockwise, the left side is vertically upward, while the right side of the gear 9 is vertically downward, so the first gear ring 5 and the second gear ring 6 rotate in opposite directions.

[0025] By arranging the spiral spray head 8 on the winch that winds the steel wire 3 into a steel cable, and arranging the first gear ring 5 on the winch, the first gear ring 5 drives the second gear ring 6 to rotate in the opposite direction through the gear 9, and arranging the outer spray head 7 in the second gear ring 6, the effect of uniform spraying can be achieved without adding an additional power source, thereby realizing the effective use of energy;

[0026] A spiral spray head 8 is arranged inside the first gear ring 5 for spraying lubricating oil on the steel wire 3 from the inside to the outside. The spiral spray head 8 rotates in the same direction as the first gear ring 5. A plurality of groups of outer spray heads 7 are arranged on the inner wall of the second gear ring 6 for spraying lubricating oil on the steel wire 3 from the outside to the inside. The outer spray heads 7 are driven to rotate by the second gear ring 6. The spiral spray heads 8 and the outer spray heads 7 rotate in opposite directions, leaving time for the lubricating oil to flow to the opposite side, so that the sprayed lubricating coating is more evenly distributed.

[0027] At least two groups of gears 9 are arranged along the circumference to ensure the stability of the operation between the first gear ring 5 and the second gear ring 6;

[0028] The mounting frame 11 is mounted on the surface of the material collecting box 12, and the material collecting box 12 is used to recover the lubricating oil sliding off the steel wire 3, thereby avoiding the waste of materials;

[0029] The spiral spray head 8 is spiral-shaped, and multiple groups of spray heads are distributed on it. The lubricating oil is sprayed radially toward the steel wire 3, so that the spiral spraying of the lubricating oil can cover more evenly;

[0030] Therefore, an outer layer nozzle 7 is provided to spray the lubricating oil from the outside to the inside, and a spiral nozzle 8 is provided to spray the lubricating oil from the wound inner layer to the outside. The lubricating oil is sprayed evenly inside and outside, thereby reducing the lubricating oil consumption and ensuring that the surface of the steel wire 3 is completely covered with the lubricating oil. This solves the problem in the prior art that due to the limited angle of spraying the lubricating oil and the steel wire 3 itself playing a guiding role, a lot of lubricating liquid is diverted by the steel wire 3 to the unwound part, while part of the steel wire 3 located inside the steel cable cannot be completely covered by the lubricating oil, causing the steel wires 3 in this part to rub against each other, thereby affecting the service life of the steel cable.

Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
