Description

An assembly for lifting and a harbour crane comprising the assembly
Description
Technical Field
[1 ] The present invention is relating to an assembly for lifting in harbour crane.
The assembly comprises at least one elongated element and a polymer layer surrounding this elongated element. The present invention further relates to the application of such an assembly in a harbour crane. The present invention also relates to a harbour crane using such an assembly and a reel.
Background Art
[2] An assembly comprising one or more elongated elements as reinforcement and a polymer surrounding the one or more elongated elements is known in the art of elevators. For example, US6739433 discloses a flat belt for lifting elevator; US2004216958 discloses a belt having a running surface facing the drive pulley with a plurality of ribs and grooves extending in parallel in a longitudinal direction of the belt. In elevators, these assemblies have the great advantage of allowing a compact design of the elevator and enable the saving of an additional floor for the machine room of the elevator.
[3] However, up to now these assemblies have been limited to elevators and have not found extensive application elsewhere.
Disclosure of Invention
[4] It is an object of the present invention to mitigate the drawbacks of the prior art.
[5] It is also an object of the present invention to amend the design of the assembly so that it can be efficiently used in other applications such as harbour cranes.
[6] It is another object of the present invention to provide a harbour crane lifted by the assembly. [7] It is also another object of the present invention to provide a reel for paying-off and taking-up and an assembly.
[8] According to a first aspect of the present invention, there is provided an assembly for lifting. The assembly comprises at least one elongated element and a polymer layer surrounding this elongated element. The assembly has an upper side and a lower side. The upper side and the lower side are mutually opposing. The upper side is provided with a first profiled surface and the lower side is provided with a second profiled surface. The second profiled surface is engaging with the first profiled surface when the assembly is coiled or wound.
[9] The profiles in the upper and lower side may engage with each other so that when the assembly is wound and forms various windings, there is an efficient transmission of forces between the various windings. In contrast with the prior art, the upper side and the lower side are no longer flat. Instead they engage with one another and movement of one winding with respect to another winding is limited because of the engaging or anchoring profiles.
[10] There are various ways of providing engaging profiles. Preferably, the first profiled surface has at least one groove or tooth while the second profiled surface has at least one tooth.
[1 1 ] The groove or tooth may be set along the longitudinal direction of the assembly, along the transverse direction of the assembly or along the direction at an angle with the longitudinal direction of the assembly.
[12] The groove or the tooth may have various forms or geometries. For example, they may have a cross-section of a triangle, a trapezoid, a rectangle, a square, a semicircle or a semi-oval.
[13] Because of the tooth and groove, the surface of the upper side and the surface of the lower side are not flat and smooth, and the cross-section of the assembly can only be close to be flat, rectangular, Z-figure, V-figure or U-figure which is called substantially flat, substantially rectangular, substantially Z-figure, substantially V-figure or substantially U-figure. 'Flat' here means a figure with two parallel lines and two arc edges.
[14] The cross-section of the assembly may also have various forms or geometries. For example, the assembly has a flat (as long as it is not the same cross-section over the whole length), rectangular (as long as it is not the same cross-section over the whole length), substantially flat, substantially rectangular, substantially Z-figure, substantially V-figure or substantially U-figure cross-section.
[15] The assembly may have a plurality of elongated elements aligning in parallel with a distance between each other. Preferably this distance has a value being 0.2 to 0.5 times the diameter of the elongated element.
[16] The elongated element may be a metal cord, a polymer cord, a hybrid cord, a metal wire or a polymer wire, e.g. a steel cord or a steel wire. Here hybrid cord means a cord comprising both metal wires and polymer wires.
[17] The elongated element may have a round, oval, flat or rectangular cross- section.
[18] Preferably the tooth height has a value being 0.05 to 0.2 times the diameter of the elongated element.
[19] To the oval, flat or rectangular elongated element, 'the diameter' means the equivalent diameter which is to be understood as the diameter of an imaginary circle having a surface area equal to the surface of the radial cross section of the elongated element.
[20] Preferably the elongated elements are positioned at a distance from the surface of the assembly, despite the presence of profiles. Preferably this distance has value being 0.1 to 0.3 times the diameter of the elongated element. The advantage is that by covering the elongated elements with the polymer, contacts between the elongated elements are avoided thereby increasing the lifetime of the assembly. In addition, this covering increases the corrosion resistance in case of metal or even steel elongated elements.
[21 ] The polymer layer may be made of plastic or rubber material.
[22] In case of plastic, this plastic can be selected from the group of thermal polyurethane (TPU), polyurethane (PU), polyethylene (PE), polytetrafluorethylene (PTFE), polypropylene (PP) and polystyrene (PS).
[23] According to a second aspect of the present invention, the assembly is applied for lifting in an elevator, for mining, or in a crane, i.e. a harbour crane. [24] A harbour crane may be the existing harbour crane known in the art, i.e. a harbour crane with a bridge structure or a harbour crane with a door structure. This harbour crane comprises a lifting structure for the vertical movement and a car movement organization along the bridge for horizontal movement of the load. The lifting structure comprises a reel and an assembly according to the first aspect of the invention.
[25] According to another aspect of the invention, there is provided a reel for paying-off and taking-up and an assembly according to the first aspect of the invention. The reel has a groove to fix the end of the assembly.
[26] According to still another aspect of the invention, there is provided a reel for paying-off and taking-up and an assembly according to the first aspect of the invention. The reel has a profile engaging with the assembly thereby improving the transfer of forces between the reel and the assembly.
[27] The groove in the reel or the profile on the reel is set for fixing the assembly with the reel and limiting the movement between the assembly and the reel.
[28] Further, the reel may have both the groove to fix the end of the assembly and the profile to engage with the assembly.

[48] The assembly for lifting has an upper side and a lower side. The upper side and the lower side are mutually opposing. For a good engagement between the upper side and lower side while coiling the assembly, the upper side is provided with a first profiled surface, and the lower side is provided with a second profiled surface.
[49] The first profiled surface has at least one groove or tooth and the second profiled surface has at least one tooth. The groove or the tooth can be set in any place of the upper side, i.e. in the middle of the upper side or near the edge of the upper side.
[50] The 'upper side' means one side of the assembly to distinguish with another side, 'upper' doesn't mean the direction of the side. The 'lower side' just means another side of the assembly, 'lower' doesn't mean the direction of the side. The upper side is provided with a first profiled surface, while the lower side is provided with a second profiled surface. The first profiled surface has at least one groove or tooth while said second profiled surface has at least one tooth, which means both of the two profiled surfaces may have tooth, or one profiled surface has groove while another profiled surface has tooth.
[51 ] Figure 1 illustrates a first embodiment of the present invention. The assembly 10 comprises steel cords 2 and a PU layer 14 surrounding the steel cords 2. The assembly 10 has a substantially rectangular cross- section. The assembly 10 has an upper side 8 and a lower side 12. Along the longitudinal direction of the assembly 10, the upper side 8 is provided with a groove 4 to form a first profiled surface and the lower side 12 is provided with a tooth 6 to form a second profiled surface. Because of the groove 4 and the tooth 6, the upper side 8 and the lower side 12 can engage well while coiling the assembly 10. The groove 4 and the tooth
6have a cross-section of a trapezoid with an angle of 45°. The H, height of the tooth 6, is preferably 0.05 to 0.2 times the diameter of the steel cord 2. The groove 4 is set in the middle of the upper side.
[52] According to the present invention, the angle a is more than 0° and not more than 90°.
[53] To make the assembly stable and un-easy to be broken, the elongated elements are positioned at a distance from the surface of the assembly, despite the presence of profiles, and the distance preferably has a value being 0.1 to 0.3 times the diameter of the elongated element. The Figure 2 shows the front view of the assembly 10. H' in figure 2 shows the distance from the surface 8 of the assembly to the elongated element 2.
[54] Figure 3 illustrates a second embodiment of the present invention. The assembly 16 has an upper side 18 and a lower side 20. The upper side 18 and the lower side 20 can engage well while winding or coiling the assembly 16. Different from the first embodiment, the upper side 18 is provided with two grooves 22 to form a first profiled surface and the lower side 20 is provided with two teeth 24 to form a second profiled surface. The grooves 22 and teeth 24 are set along the longitudinal direction of the assembly 16.
[55] Figure 4 illustrates a third embodiment of the present invention. The assembly 26 has a substantially flat cross-section. The flat figure has two parallel lines and two arc edges connecting the two parallel lines. The assembly 26 comprising steel cords 28 and a TPU layer 29 has an upper side 30 and a lower side 32. The upper side 30 has grooves 34 and the lower side 32 has teeth 36. The grooves 34 and the teeth 36 have a cross- section of a semi-oval. The upper side 30 and the lower side 32 can engage well while winding or coiling the assembly 26. The grooves 34 and teeth 36 are set along the longitudinal direction of the assembly 26.
[56] Figure 5 illustrates a fourth embodiment of the present invention. The assembly 38 has a substantially V-figure cross-section. The assembly 38 has grooves on the upper side and teeth on the lower side. The upper side and the lower side can engage well while winding or coiling the assembly 38. The grooves and teeth are set along the longitudinal direction of the assembly 38.
[57] Figure 6 illustrates a fifth embodiment of the present invention. The assembly 40 has a substantially Z- figure cross-section. The assembly 40 has grooves on the upper side and teeth on the lower side. The upper side and the lower side can engage well while winding or coiling the assembly 40. The grooves and teeth are set along the longitudinal direction of the assembly 40.
[58] The grooves on one side may be set with a distance with each other, i.e. the grooves in the embodiment the second to fifth, otherwise the grooves may be set without any distance with each other.
[59] Figure 7 illustrates a sixth embodiment of the present invention. The assembly 50 has an upper side 42 and a lower side 44. The grooves 46 on the upper side 42 are set one by one, which means there is no distance between the adjacent grooves 46. Because of the grooves 46 and teeth 48, the upper side 42 and the lower side 44 can engage well while winding or coiling the assembly 50. The grooves 46 are set along the longitudinal direction of the assembly 50. [60] Figure 8 illustrates a seventh embodiment of the present invention. The assembly 52 has a substantially U-figure cross-section. The upper side and the lower side can engage well while winding or coiling the assembly 52. The grooves and teeth are set along the longitudinal direction of the assembly 52.
[61 ] Figure 9 illustrates an eighth embodiment of the present invention. The assembly 56 has an upper side 58 and a lower side 60. Both the upper side 58 and the lower side 60 have teeth 62. The upper side 58 and the lower side 60 can engage well while winding or coiling the assembly 56. The teeth 62 are set along the longitudinal direction of the assembly 56.
[62] The groove and the tooth may be set along the longitudinal direction and / or transversal direction of the assembly, or along the direction at an angle with the longitudinal direction of the assembly.
[63] Figure 10 illustrates a ninth embodiment of the present invention. The grooves 66 and the teeth 68 are set along the transversal direction of the assembly 64.
[64] Figure 1 1 illustrates a tenth embodiment of the present invention. The groove 72 and the tooth 76 are set along the longitudinal direction of the assembly 70, while the groove 74 and the tooth 78 are set along the transversal direction of the assembly 70.
[65] Figure 12 illustrates an eleventh embodiment of the present invention. The teeth 82 are set in both upper side and lower side along the transversal direction of the assembly 80.
[66] The elongated element in the present invention for reinforcing the assembly may be a cord or a wire. The cord may be any existing cord, i.e. steel cord, organic fiber cord or the hybrid cord comprising steel wires and organic fibers. The wire may be any existing wire, i.e. steel wire comprising carbon.
[67] The elongated elements, i.e. cords or wires, inside the assembly may have the same diameter or the different diameter.
[68] Figure 13 illustrates a twelfth embodiment of the present invention. The assembly 54 has steel cords 28 and steel cords 2. The diameter of steel cord 28 is smaller than the diameter of the steel cord 2.
[69] Figure 14 to Figure 16 illustrate several cords for reinforcing the assembly. [70] Figure 14 illustrates a steel cord 2 with a structure of 7*(1 +6+12). Figure
15 illustrates a Warrington cord 28. Figure 16 illustrates a cord 53 with a PU cover 55.
[71 ] The diameter of the elongated element may be any diameter known in the art. With the increase of the diameter, the strength of the elongated element increases.
[72] When the assembly is wound and forms various windings, there is an efficient transmission of forces between the various windings. The first profile and the second profile form the engaging or anchoring profiles. The windings engage with one another and movement of one winding with respect to another winding is limited because of these engaging or anchoring profiles.
[73] A reel for paying-off and taking-up and an assembly is also provided according to the present invention. The assembly is well wound on the reel because of the first profiled surface and the second profiled surface.
[74] Figure 17 illustrates one example of a reel and an assembly. To fix the end of the assembly 10 with the reel 84, the reel 84 is set with a groove 86 which has a shape adapting for holding the end of the assembly 10.
[75] Figure 18 illustrates another example of a reel and an assembly. To wind the assembly 50, the winding surface 90 of the reel 88 is shaped to have a profile engaging with said assembly 50.
[76] Of course, the reel may have both a groove to fix the end of assembly and a profile engaging with said assembly.
[77] Figure 19 illustrates a harbour crane according to the present invention.
The harbour crane 92 has a bridge structure. The harbour crane 92 has a lifting structure for vertical movement and a car movement organization along the bridge structure for horizontal movement, wherein the lifting structure comprises a reel 84 and an assembly 10.
