Description

Technical Field

[0001] This utility model relates to the field of rain cover technology, and in particular to a rain cover with a water-permeable structure. 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 machine room roof through the arrangement of a cylinder and a sealed cover. Traditional rain cover designs often lack dedicated drainage structures or channels, leading to rainwater accumulation inside the cover and inability to drain in time, resulting in corrosion and rust of internal components. Furthermore, although the above-mentioned rope exit cover structure adapts to the wire rope exit requirements through designs such as rotating mechanisms and sealing elements, its adaptability remains limited for slight oscillations of the wire rope or wire ropes of different diameters.

[0004] Therefore, it is necessary to design a simple structure with drainage and rain protection to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rain cover with a water-permeable structure, which solves the problems of complex structure of rain cover, difficulty in installation and maintenance, and inability to drain rainwater.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A rain cover with a water-passing structure includes a fixed bucket 1 and a swing bucket 2 hinged to the upper middle part of the fixed bucket 1. A part of the fixed bucket 1 is covered inside the swing bucket 2. A water-passing channel 7 is reserved between the front inner wall of the swing bucket 2 and the front outer wall of the fixed bucket 1, and between the rear inner wall of the swing bucket 2 and the rear outer wall of the fixed bucket 1.

[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 fixed barrel 1 protrudes outward on both sides of the corresponding position of the hinge portion 23 to form a first protrusion 111 and a second protrusion 112, and a space for the installation of the hinge member 5 is formed between the first protrusion 111 and the second protrusion 112.

[0010] Preferably, the swing bucket 2 is provided with a large opening 21 for the fixed bucket 1 to pass through and a small opening 22 for the external steel wire rope to pass through. The shape of the swing bucket 2 is a triangular shape that diffuses and extends from the small opening 22 to the large opening 21.

[0011] Preferably, a first connecting seat 4 is connected to the small opening 22, and an auxiliary roller group 3 is installed on the first connecting seat 4. The auxiliary rollers of the auxiliary roller group 3 form a guide channel 31 for the steel wire rope to pass through into the swing bucket 2.

[0012] Preferably, the auxiliary roller group 3 consists of two symmetrically arranged rollers 301, wherein the rollers 301 are grooved rollers, so that a circular guide channel 31 matching the wire rope is formed between the two rollers 301.

[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 the 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 91 is located on the outer side of the middle of the front side wall of the fixed bucket 1.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The rain cover designed in this case has a water passage 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 cover, it can be quickly discharged through the water passage, avoiding the accumulation of rainwater inside the cover, thereby reducing the risk of rainwater damage to the equipment and the rain cover itself.

[0016] 2. The design of the first and second protrusions in this case creates a space between them for the installation of the hinge. This serves two purposes: firstly, it ensures a gap between the swing bucket and the fixed bucket, forming the water passage; secondly, the gap prevents the swing bucket and the fixed bucket from being tightly fitted together, preventing water flowing through the water passage from entering the fixed bucket; and thirdly, it acts as a barrier while facilitating positioning and installation.

[0017] 3. The number of components and connection points of the rain cover in this case has been greatly reduced, including only key components such as the fixed bucket, swing bucket, and auxiliary roller assembly, which simplifies the installation and maintenance process and reduces the difficulty and cost of operation.

[0019] Figure 2 This is one of the three-dimensional structural schematic diagrams of this utility model;

[0020] Figure 3 This is the second three-dimensional structural schematic diagram of the present invention. Detailed Implementation

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown, the rain cover with a water-permeable structure of this utility model includes a fixed bucket 1 and a swing bucket 2 hinged to the upper middle part of the fixed bucket 1. A part of the fixed bucket 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 bucket 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. A first connecting seat 4 is connected to the small opening on the side of the swing bucket 2 that is not connected to the fixed bucket 1. An auxiliary roller group 3 is installed on the first connecting seat 4. Two symmetrically arranged auxiliary rollers 301 are installed on the first connecting seat 4, and a guide channel 31 is formed between the two auxiliary rollers 301. The steel wire rope can enter the interior of the swing bucket 2 along the guide channel 31. A water-permeable channel 7 is reserved between the front inner wall of the swing bucket 2 and the front outer wall of the fixed bucket 1, and between the rear inner wall of the swing bucket 2 and the rear outer wall of the fixed bucket 1.

[0023] In practical implementation, the triangular shape of the swing bucket allows the rain cover to effectively utilize the space on the machine room roof while covering the steel wire rope, avoiding space waste caused by the large structure. In actual use, the rain cover is installed at an angle, placing the swing bucket at a higher position and the fixed bucket 1 at a lower position. The steel wire rope passes through the guide channel 31, enters the swing bucket 2, and exits from the bottom opening of the fixed bucket 1. When the steel wire rope carrying 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 passage 7 due to the friction of the auxiliary rollers and the effect of gravity. Alternatively, when raindrops fall into the swing bucket 2, they also flow out along the water passage 7 due to gravity.

[0024] As mentioned above, this design incorporates a water passage between the swing bucket and the fixed bucket, effectively mitigating the problem of rainwater accumulation. When rainwater falls onto the rain cover, it can be quickly drained through the water passage, preventing rainwater from accumulating inside the cover and thus reducing the risk of damage to the equipment and the rain cover itself. The rain cover only includes the fixed bucket 1, swing bucket 2, auxiliary roller assembly 3, and first connecting seat 4, reducing the number of components and connection points, thereby lowering the complexity and cost of installation and maintenance, and also reducing the risk of malfunctions due to component damage or loosening.

[0025] like Figure 2 and Figure 3 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. Unlike existing technologies 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. Simultaneously, the raised hinge portion also provides a more robust support point, enhancing the connection strength between the swing bucket and the fixed bucket.

[0026] like Figure 1 As shown, the fixed bucket 1 has a first protrusion 111 and a second protrusion 112 protruding outwards on both sides of the hinge portion 23 at the corresponding positions. A space for the hinge member 5 to be installed is formed between the first protrusion 111 and the second protrusion 112. On the one hand, this ensures that there is a gap between the swing bucket 2 and the fixed bucket 1 to facilitate the formation of the water passage 7; moreover, the gap prevents the swing bucket 2 and the fixed bucket 1 from being tightly fitted together, preventing water flowing through the water passage 7 from entering the fixed bucket 1; on the other hand, it serves as a barrier while facilitating positioning and installation.

[0027] like Figure 1 and Figure 2 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.

[0028] like Figure 1 and Figure 3As shown, the fixed bucket 1 has openings at both the top and bottom, and its lower part communicates with 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 91 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 resistance to overturning and torsion. In specific implementation, the corner frame 9 is welded to the fixed bucket.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
