Abstract

According to the rain cover, through the hinged design of a swing hopper and the adjustability of an auxiliary roller set, the good adaptability to steel wire ropes with different diameters and tiny swing of the steel wire ropes is achieved. Particularly, due to the design of the second screw holes in the auxiliary roller group, the reserved gaps allow the auxiliary rollers to be finely adjusted according to the thickness of the steel wire rope, so that the steel wire ropes with different specifications are effectively supported and guided, and the abrasion of the steel wire rope is reduced. The water passing channel is reserved between the swing hopper and the fixed barrel, so that the problem of rainwater accumulation can be effectively solved, and the damage risk of rainwater to equipment and the rain cover is reduced. According to the scheme, the rainproof cover only comprises the fixed barrel, the swing bucket, the auxiliary roller group, the first connecting seat, the first screw hole and the second screw hole, so that the number of parts and connecting points are reduced, the complexity and cost of installation and maintenance are reduced, and the fault risk caused by damage or looseness of the parts is also reduced.

Description

Technical Field

[0001] The invention relates to the technical field of rainproof covers, in particular to a rainproof cover. Background Art

[0002] The wire rope rain cover of the crane is an important protective device, which is designed to protect the wire rope from erosion by 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 number CN203229320U discloses a rope outlet cover structure for a gantry crane, which can effectively solve the problem of rain leakage on the roof of the machine room by arranging a cylinder and a sealing cover. When the wire rope is released or collected, the sealing rubber skin in contact with the wire rope moves with the rollers arranged in a "well" shape, reducing the friction of the wire rope, thereby reducing the degree of wear of the wire rope, extending the service life of the wire rope, occupying a small space, and facilitating the arrangement of the wire rope outlet on the roof of the machine room. However, it contains multiple components and connection points, which is relatively complicated during installation and maintenance, increasing the difficulty and cost of operation. Moreover, in the traditional rain cover design, there is often a lack of a special drainage structure or drainage channel, which causes rainwater to easily accumulate inside the cover and cannot be discharged in time, thereby causing corrosion and rust of internal components. In addition, although the above rope outlet cover structure is designed to adapt to the wire rope outlet demand through a rotating mechanism and a sealing element, its adaptability is still limited for the slight swing of the wire rope or wire ropes of different diameters.

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 6As shown, the rain cover of the present invention comprises a fixed barrel 1 and a swing bucket 2 hinged to the upper end of the middle of the fixed barrel 1, a part of the fixed barrel 1 is covered inside the swing bucket 2; the swing bucket 2 can swing around the screw to limit the left and right; the swing bucket 2 is provided with a large opening 21 for the fixed barrel 1 to pass through and a small opening 22 for the external wire rope to pass through, so that the swing bucket 2 is in a triangular shape extending from the small opening 22 to the large opening 21. An auxiliary roller group 3 is connected to the small opening on the side opening not connected to the fixed barrel 1, and the small opening is connected to a first connecting seat 4, on which two symmetrically arranged auxiliary rollers 301 are installed, and a guide channel 31 is formed between the two auxiliary rollers 301, and the wire rope can enter the inside of the swing bucket 2 along the guide channel 31. The first connection seat 4 is provided with two screw holes arranged side by side, which are divided into a first screw hole 41 and a second screw hole 42. The size of the first screw hole 41 is just enough for the screw for installing the auxiliary roller to pass through, and the second screw hole 42 is provided with a gap 43 after the screw for installing the auxiliary roller passes through, so as to be able to adapt to different thicknesses of steel wire ropes. A water passage 7 is provided between the front inner wall of the swing bucket 2 and the front outer wall of the fixed bucket 1 / between the rear inner wall of the swing bucket 2 and the rear outer wall of the fixed bucket 1.

[0029] During specific implementation, the size of the small opening is slightly larger than the diameter of the wire rope to ensure that the wire rope can pass smoothly. The triangular shape design of the swing bucket allows the rain cover to cover the wire rope while more effectively utilizing the space on the roof of the machine room, avoiding the problem of space waste caused by the bulky structure. In actual use, the rain cover of this case is installed at an angle, so that the swing bucket is at a high place and the fixed barrel 1 is at a low place. The external wire rope enters the swing bucket 2 from the guide channel 31 and then passes through the bottom opening of the fixed barrel 1; or passes through the swing bucket 2 from the bottom opening of the fixed barrel 1 and then passes through the guide channel 31. When the wire rope with water passes through the guide channel 31, the water droplets fall to one side of the swing bucket 2 and flow out along the water channel 7 through the friction of the auxiliary roller and the action of gravity, so that rainwater will not flow into the fixed barrel. Or when raindrops fall into the swing bucket 2, they also flow out along the water channel 7 under the action of gravity. Since it is installed at an angle and there is a gap 43, the auxiliary roller in the second screw hole 42 can fit the wire rope due to the decrease of gravity. During the process of the wire rope entering and exiting, the engine oil, sand, rainwater, etc. are scraped off to the outside of the rain cover through friction, further reducing the impurities that flow into the swing bucket or the bottom of the water, and protecting the inside of the rain cover.

[0030] As mentioned above, the rain shield designed in this case achieves good adaptability to wire ropes of different diameters and small swings of wire ropes through the hinged design of the swing bucket and the adjustability of the auxiliary roller group. In particular, the second screw hole design on the auxiliary roller group, the reserved gap allows the auxiliary roller to be fine-tuned according to the thickness of the wire rope, ensuring the effective support and guidance of wire ropes of different specifications, and reducing the wear of the wire rope. The rain shield of this case only includes the fixed bucket 1, the swing bucket 2, the auxiliary roller group 3, the first connecting seat 4 and the first screw hole 41 and the second screw hole 42, which reduces the number of components and connection points, thereby reducing the complexity and cost of installation and maintenance, and also reduces the risk of failure caused by damage or looseness of components. A water passage is reserved between the swing bucket and the fixed bucket. This design can effectively improve the problem of rainwater accumulation. When rainwater falls on the rain shield, it can be quickly discharged through the water passage to avoid rainwater accumulation inside the cover, thereby reducing the risk of rainwater damage to the equipment and the rain shield itself.

[0031] like Figure 3 As shown, a swing space 6 is reserved between the inner wall of the swing bucket 2 and the edges of both sides of the fixed barrel 1. 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 and different diameter changes of the wire rope, which not only improves the adaptability of the rain cover, but also reduces the friction and wear caused by the movement of the wire rope, further extending the service life of the rain cover and the wire rope.

[0032] like Figure 1 and Figure 5 As shown, the top of the swing bucket 2 is a structure that tilts downward from the middle to both sides, so as to form a raised hinge 23 in the middle of the top, and a detachably connected hinge 5 is installed on the hinge 23. Different from the prior art, where the top is a plane, the tilted design of the top of the swing bucket makes the hinge located at the high point of the structure. Such a layout helps to disperse the stress and torque generated by the swing bucket during the swinging process, thereby improving the stability and durability of the entire structure. At the same time, the raised hinge also provides a more solid support point, which enhances the connection strength between the swing bucket and the fixed bucket.

[0033] like Figure 1As shown, the fixed barrel 1 includes: a first shell 11 and a second shell 12, the first shell 11 is provided with a first mounting ridge 111 on both sides thereof, and a plurality of screw holes are evenly opened on the first mounting ridge 111; the second shell 12 is provided with a second mounting ridge 121 on both sides thereof, and a plurality of screw holes corresponding to the screw holes of the first mounting ridge 111 are evenly opened on the second mounting ridge 121. During installation, the first mounting ridge 111 and the second mounting ridge 121 on the same side are attached and the screw holes are aligned, and then the first shell 11 and the second shell 12 are assembled together by tightening with a plurality of first screws 13. In some embodiments, the width of the first mounting ridge 111 and the second mounting ridge 121 is 1 / 2 of the distance from the edge of one side of the first shell 11 / the second shell 12 to the inner wall of the swing bucket 2.

[0034] As described above, the first shell 11 and the second shell 12 are connected by the installation ridges, corresponding screw holes and the first screws to achieve accurate alignment. The setting of the first installation ridge 111 and the second installation ridge 121, on the one hand, makes the swing bucket 2 contact the relatively small installation ridge instead of the entire side of the fixed barrel when it swings, reducing the contact area, thereby reducing wear and saving costs; on the other hand, it increases the contact area between the first shell and the second shell, making the connection between the two more secure. The cooperation 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 shocks and vibrations, and protecting the wire rope and other components inside the fixed barrel from damage. In addition, by limiting the distance from the outer wall of one side of the first shell 11 / second shell 12 to the inner wall of the swing bucket 2, the swing bucket can be prevented from swinging excessively.

[0035] like Figure 2 As shown, in some embodiments, the first mounting ridge 111 and the second mounting ridge 121 have rounded corners 8 at their upper and lower edges; on the one hand, this is to reduce the wear between the two when the swing bucket 2 swings, and on the other hand, it is convenient for the installer to grasp it during installation without hurting his hands.

[0036] like Figure 1 and Figure 2As shown, the fixed barrel 1 is provided with a through-port structure at the top and bottom, and the lower part of the fixed barrel 1 is connected with the swing bucket 2; the fixed barrel 1 is also connected with a corner frame 9 at the upper part, and the corner frame 9 is a rectangular frame structure, and is provided 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 obliquely connected to the left and right sides of the fixed barrel 1, so that the second frame bar 92 is located on the outside of the top of the rear side wall of the fixed barrel 1, and the first frame bar 92 is located on the outside of the middle of the front side wall of the fixed barrel 1. In this way, the corner frame 9, as a supporting structure of the fixed barrel 1, effectively enhances the overall stability and bearing capacity of the fixed barrel 1 through its rectangular frame design. In particular, the third frame bar 93 and the fourth frame bar 94 are obliquely connected to the left and right sides of the fixed barrel 1, on the one hand, forming a stable structure similar to a triangle, further improving the anti-overturning and anti-torsion capabilities; on the other hand, it can avoid the first mounting convex bar 111 and the second mounting convex bar 121 for installation, and the structure is more compact and reasonable. During specific implementation, the angle bracket 9 is welded to the fixed barrel by welding.

[0037] like Figure 1 As shown, the third frame bar 93 and the fourth frame bar 94 are both provided with a strip convex edge 95 extending outward from the bottom surface thereof, so that the third frame bar 93 and the fourth frame bar 94 are in an L-shaped structure; the strip convex edge 95 overlaps the first mounting convex strip 111 and the second mounting convex strip 121 when connected obliquely. In this way, the strip convex edge 95 and the design of the strip convex edge overlapping the mounting convex strip can form a tighter fit and reduce looseness or displacement caused by vibration or external force. The third and fourth frame bars of the L-shaped structure not only increase their own strength, but also form the angle bracket 9 and the fixed barrel 1 into a whole through the connection between the strip convex edge and the mounting convex strip, further improving the strength and rigidity of the entire structure.

[0038] like Figure 1 and Figure 2As shown, the swing bucket 2 includes: a bottom plate 201 located at the front side, and a connecting shell 202 fixedly connected to the rear side of the bottom plate 201 by a second screw 204; the left and right edges of the front side wall or the rear side wall of the connecting shell 202 extend outward to form a connecting edge 203 for connection; a plurality of the second screws 204 evenly pass through the connecting edge 203 and fasten the bottom plate 201 and the connecting shell 202 together. In this way, through the combination of the bottom plate 201 and the connecting shell 202 and the fixed connection of the second screws 204, the structure of the swing bucket 2 is more stable and can withstand greater external force and pressure, thereby improving the overall stability and safety of the rain cover. The design of the connecting edge 203 increases the contact area between the connecting shell 202 and the bottom plate 201, and provides a more secure fixing point for the second screw 204. Since the various components of the swing bucket 2 are connected by screws, maintenance is more convenient. The various components of the swing bucket 2 can be disassembled by simply loosening the screws, thereby reducing maintenance costs and time costs.

[0039] like Figure 4 and Figure 5 As shown, the auxiliary roller set 3 is composed of two symmetrically arranged auxiliary rollers 301, and the auxiliary rollers 301 are groove rollers, so that a circular guide channel 31 matching the steel wire rope is formed between the two rollers 301. In this way, the design of the groove roller increases the contact area and friction between the steel wire rope and the groove roller, making the steel wire rope more stable when moving on the roller; on the other hand, it can more evenly distribute the pressure of the steel wire rope on the roller, reducing the wear between the roller and the steel wire rope.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
