Abstract
Description
Technical Field
[0001] This invention relates to the field of rain cover technology, and in particular to a rain cover with an adaptive cord delivery mechanism. Background Technology
[0002] The wire rope rain cover for cranes is an important protective device designed to protect the wire rope from environmental factors such as rain and dust, thereby extending the service life of the wire rope and ensuring the normal operation and safety of the crane.
[0003] Chinese Patent Publication No. CN203229320U discloses a rope exit cover structure for a gantry crane, which effectively solves the problem of rain leakage in the crane room roof by arranging a cylinder and a sealing cover. When the wire rope is released or retracted, it slips, causing the sealing rubber sheet in contact with the wire rope and the "well"-shaped arranged idlers to move accordingly, reducing the friction of the wire rope, thereby reducing wear and extending its service life. It occupies little space and is beneficial for the arrangement of the wire rope exit on the crane room roof. However, it contains multiple components and connection points, making installation and maintenance relatively complex, increasing operational difficulty and cost. Furthermore, although the above rope exit cover structure adapts to the wire rope exit requirements through designs such as rotating mechanisms and sealing elements, its adaptability is still limited for slight oscillations of the wire rope or wire ropes of different diameters.
[0004] Therefore, it is necessary to design an adaptive rope-out rain cover to solve the above-mentioned technical problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the present invention aims to provide an adaptive wire rope delivery rain cover, which solves the problems of complex structure, difficulty in installation and maintenance, and inability to adaptively deliver wire ropes.
[0006] The technical solution adopted in this invention is as follows:
[0007] An adaptive rope delivery rain cover includes a fixed bucket 1 and a swing bucket 2 hinged to the upper middle part of the fixed bucket 1. A portion of the fixed bucket 1 is covered inside the swing bucket 2. The swing bucket 2 has a large opening 21 for the fixed bucket 1 to pass through and a small opening 22 for an external steel wire rope to pass through. A first connecting seat 4 is connected to the small opening 22. An auxiliary roller assembly 3 is installed on the first connecting seat 4. The auxiliary rollers of the auxiliary roller assembly 3 form a guide channel 31 for the steel wire rope to pass into the swing bucket 2. The first connecting seat 4 has two screw holes arranged side by side, namely a first screw hole 41 and a second screw hole 42. The size of the first screw hole 41 matches the size of the screw for installing the auxiliary roller assembly. The second screw hole 42 is enlarged based on the size of the first screw hole 41 to leave a gap 43, so as to adapt to the rope delivery action of the external steel wire rope.
[0008] Preferably, the top of the swing bucket 2 has a structure that slopes downward from the middle to both sides, so as to form a raised hinge portion 23 in the middle of the top, and a detachable hinge member 5 is installed on the hinge portion 23.
[0009] Preferably, the inner wall of the swing bucket 2 and the two side edges of the fixed bucket 1 are provided with a swing space 6.
[0010] Preferably, the fixed bucket 1 includes: a first housing 11 and a second housing 12, the first housing 11 is provided with first mounting protrusions 111 on both sides, and the second housing 12 is provided with second mounting protrusions 121 on both sides; the first mounting protrusions 111 and the second mounting protrusions 121 are evenly provided with a plurality of corresponding screw holes, and a plurality of first screws 13 are installed on the plurality of screw holes.
[0011] Preferably, the width of the first mounting protrusion 111 and the second mounting protrusion 121 is half the distance from the outer wall of the first housing 11 / second housing 12 to the inner wall of the swing bucket 2.
[0012] Preferably, the first mounting protrusion 111 and the second mounting protrusion 112 have rounded corner treatment portions 8 on their upper and lower side edges.
[0013] Preferably, the fixed bucket 1 has openings at both the top and bottom, and the lower part of the fixed bucket 1 is connected to the swing bucket 2; the upper part of the fixed bucket 1 is also connected to a corner frame 9, which is a rectangular frame structure with a first frame strip 91, a second frame strip 92, a third frame strip 93, and a fourth frame strip 94; the third frame strip 93 and the fourth frame strip 94 are obliquely connected to the left and right sides of the fixed bucket 1, such that the second frame strip 92 is located on the outer side of the top of the rear side wall of the fixed bucket 1, and the first frame strip 92 is located on the outer side of the middle of the front side wall of the fixed bucket 1.
[0014] Preferably, both the third frame strip 93 and the fourth frame strip 94 are provided with strip-shaped protrusions 95 extending outward from their bottom surfaces; the strip-shaped protrusions 95 overlap the first mounting protrusion 111 and the second mounting protrusion 121 when they are connected at an angle.
[0015] Preferably, the auxiliary roller group 3 consists of two symmetrically arranged auxiliary rollers 301, wherein the auxiliary rollers 301 are grooved rollers, so that a circular guide channel 31 matching the wire rope is formed between the two rollers 301.
[0016] Preferably, the shape of the swing bucket 2 is a triangular shape that extends from the small opening 22 to the large opening 21.
[0017] The beneficial effects of this invention are as follows:
[0018] 1. The adaptive rope delivery rain cover designed in this case significantly improves adaptability to wire ropes of different diameters and minor oscillations through the hinged design of the swing bucket and the adjustability of the auxiliary roller assembly. In particular, the design of the second screw hole on the auxiliary roller assembly allows the auxiliary rollers to be finely adjusted according to the thickness of the wire rope, effectively supporting and guiding the wire rope, significantly reducing wire rope wear and extending its service life.
[0019] 2. The number of components and connection points of the rain cover in this case has been significantly reduced, including only key components such as the fixed bucket, swing bucket, and auxiliary roller assembly. This simplifies the installation and maintenance process and reduces operational difficulty and cost. Meanwhile, the first and second shells of the fixed bucket are accurately aligned and connected via mounting ridges and screw holes, improving connection strength and structural stability, and reducing the risk of malfunctions due to component damage or loosening.

[0026] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0027] like Figures 1 to 6As shown, the adaptive rope delivery rain cover of the present invention includes a fixed barrel 1 and a swing bucket 2 hinged to the upper middle part of the fixed barrel 1. A portion of the fixed barrel 1 is covered inside the swing bucket 2. The swing bucket 2 can swing left and right around a screw. The swing bucket 2 has a large opening 21 for the fixed barrel 1 to pass through and a small opening 22 for an external steel wire rope to pass through, so that the shape of the swing bucket 2 is a triangular shape that diffuses from the small opening 22 to the large opening 21. An auxiliary roller group 3 is connected to the small opening on the side of the swing bucket that is not connected to the fixed barrel 1. A first connecting seat 4 is connected to the small opening. Two symmetrically arranged auxiliary rollers 301 are installed on the first connecting seat 4. A guide channel 31 is formed between the two auxiliary rollers 301, and the steel wire rope can enter the interior of the swing bucket 2 along the guide channel 31. The first connecting seat 4 has two screw holes arranged side by side, designated as a first screw hole 41 and a second screw hole 42. The first screw hole 41 is just the size of the screw for installing the auxiliary roller, and a gap 43 is reserved after the screw for installing the auxiliary roller passes through to accommodate wire ropes of different thicknesses. In practice, the size of the small opening is slightly larger than the diameter of the wire rope to ensure that the wire rope can pass through smoothly. The triangular shape of the swing bucket allows the rain cover to cover the wire rope while making more effective use of the space on the top of the machine room, avoiding the space waste caused by the large structure. This is especially important for space-constrained machinery such as gantry cranes. In actual use, the rain cover in this case is installed at an angle, so that the swing bucket is at a higher position and the fixed bucket 1 is at a lower position. The external wire rope enters the swing bucket 2 from the guide channel 31 and then exits from the bottom opening of the fixed bucket 1; or it enters the swing bucket 2 from the bottom opening of the fixed bucket 1 and then exits from the guide channel 31. Because it is installed at an angle, there is a gap 43. The auxiliary roller in the second screw hole 42 can come into contact with the wire rope due to gravity. During the process of the wire rope moving in and out, friction will scrape off the oil, sand, rainwater and other substances outside the rain cover.
[0028] As described above, the adaptive rope delivery rain cover designed in this case achieves good adaptability to wire ropes of different diameters and slight oscillations through the hinged design of the swing bucket and the adjustability of the auxiliary roller assembly. In particular, the design of the second screw hole on the auxiliary roller assembly, with the reserved gap, allows the auxiliary roller to be finely adjusted according to the thickness of the wire rope, ensuring effective support and guidance for wire ropes of different specifications and reducing wire rope wear. The rain cover of this case only includes the fixed bucket 1, swing bucket 2, auxiliary roller assembly 3, first connecting seat 4, and the first screw hole 41 and second screw hole 42, reducing the number of components and connection points, thereby reducing the complexity and cost of installation and maintenance, and also reducing the risk of failure due to component damage or loosening.
[0029] like Figure 3As shown, the inner wall of the swing bucket 2 and the two side edges of the fixed bucket 1 are reserved with swing space 6. In this way, the design of the swing space 6 allows the swing bucket 2 to swing more freely left and right at the hinge point, so as to better adapt to the slight swing of the wire rope and the change of different diameters. This not only improves the adaptability of the rain cover, but also reduces the friction and wear caused by the movement of the wire rope, and further extends the service life of the rain cover and the wire rope.
[0030] like Figure 1 and Figure 5 As shown, the top of the swing bucket 2 has a downward sloping structure from the middle to both sides, forming a raised hinge portion 23 in the middle of the top. A detachable hinge member 5 is mounted on the hinge portion 23. The hinge member 5 can be composed of a combination of screws and nuts. Unlike the prior art where the top is flat, the sloping design of the top of the swing bucket places the hinge portion at the highest point of the structure. This layout helps to disperse the stress and torque generated during the swing, thereby improving the stability and durability of the entire structure. At the same time, the raised hinge portion also provides a more robust support point, enhancing the connection strength between the swing bucket and the fixed bucket.
[0031] like Figure 1 As shown, the fixed bucket 1 includes a first housing 11 and a second housing 12. The first housing 11 has first mounting protrusions 111 protruding on both sides, and a plurality of screw holes are evenly formed on the first mounting protrusions 111. The second housing 12 has second mounting protrusions 121 protruding on both sides, and a plurality of screw holes corresponding to the screw holes of the first mounting protrusions 111 are evenly formed on the second mounting protrusions 121. During installation, the screw holes are aligned by aligning the first mounting protrusions 111 and the second mounting protrusions 121 on the same side, and then the first housing 11 and the second housing 12 are assembled together by tightening with a plurality of first screws 13. In some embodiments, the width of the first mounting protrusions 111 and the second mounting protrusions 121 is half the distance from one edge of the first housing 11 / second housing 12 to the inner wall of the swing bucket 2.
[0032] As described above, the first housing 11 and the second housing 12 are precisely aligned and connected through the engagement of mounting protrusions, corresponding screw holes, and first screws. The arrangement of the first mounting protrusion 111 and the second mounting protrusion 121 ensures that the swing bucket 2 contacts only the relatively small mounting protrusions instead of the entire side of the fixed bucket during swinging, reducing the contact area and thus reducing wear, while also saving costs. Furthermore, it increases the contact area between the first and second housings, making the connection between them more secure. The engagement of multiple evenly distributed screw holes and multiple first screws provides multiple fixing points, further enhancing the stability and durability of the structure, helping to resist external impacts and vibrations, and protecting the wire ropes and other components inside the fixed bucket from damage. In addition, by limiting the distance from one outer wall of the first housing 11 / second housing 12 to the inner wall of the swing bucket 2, excessive swinging of the swing bucket can be prevented.
[0033] like Figure 2 As shown, in some embodiments, the first mounting protrusion 111 and the second mounting protrusion 121 have rounded corner treatment portions 8 on their upper and lower edges; on the one hand, this reduces wear between the two when the swing bucket 2 swings, and on the other hand, it makes it easier for installers to grip without injuring their hands during installation.
[0034] like Figure 1 and Figure 2 As shown, the fixed bucket 1 has openings at both the top and bottom, and the lower part of the fixed bucket 1 is connected to the swing bucket 2. A corner frame 9 is also connected to the upper part of the fixed bucket 1. The corner frame 9 is a rectangular frame structure with a first frame bar 91, a second frame bar 92, a third frame bar 93, and a fourth frame bar 94. The third frame bar 93 and the fourth frame bar 94 are diagonally connected to the left and right sides of the fixed bucket 1, such that the second frame bar 92 is located on the outer side of the top of the rear side wall of the fixed bucket 1, and the first frame bar 92 is located on the outer side of the middle of the front side wall of the fixed bucket 1. Thus, the corner frame 9, as a supporting structure for the fixed bucket 1, effectively enhances the overall stability and load-bearing capacity of the fixed bucket 1 through its rectangular frame design. In particular, the diagonal connection of the third frame bar 93 and the fourth frame bar 94 to the left and right sides of the fixed bucket 1 forms a stable triangular structure, further improving the anti-overturning and anti-torsion capabilities; on the other hand, it avoids the first mounting protrusion 111 and the second mounting protrusion 121 for installation, resulting in a more compact and reasonable structure. In practice, the corner bracket 9 is welded to the fixed bucket.
[0035] like Figure 1As shown, both the third frame strip 93 and the fourth frame strip 94 have strip-shaped protrusions 95 extending outward from their bottom surfaces, making the third frame strip 93 and the fourth frame strip 94 have an L-shaped structure. When connected obliquely, the strip-shaped protrusions 95 overlap the first mounting protrusion 111 and the second mounting protrusion 121. This design, with the strip-shaped protrusions 95 and their overlap on the mounting protrusions, creates a tighter fit, reducing loosening or displacement caused by vibration or external forces. The L-shaped structure of the third and fourth frame strips not only increases their own strength but also, through the connection of the strip-shaped protrusions and the mounting protrusions, forms a unified structure between the corner frame 9 and the fixed bucket 1, further improving the overall strength and rigidity of the structure.
[0036] like Figure 4 and Figure 5 As shown, the auxiliary roller assembly 3 consists of two symmetrically arranged auxiliary rollers 301. Each auxiliary roller 301 is a grooved roller, creating a circular guide channel 31 between the two rollers that matches the wire rope. This grooved roller design increases the contact area and friction with the wire rope, making the wire rope more stable as it moves on the rollers. Furthermore, it distributes the pressure of the wire rope on the rollers more evenly, reducing wear between the rollers and the wire rope.
[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
