Description

Technical Field

[0001] This utility model relates to the field of rain cover technology, and in particular to a rain cover that is easy to assemble and disassemble. 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 outlet 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. The wire rope slips during release or retraction, causing the sealing rubber 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 outlet 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, due to the large size and weight of the rain cover, disassembly and assembly of heavy individual components is cumbersome, hindering maintenance and installation by personnel.

[0004] Therefore, it is necessary to design a rain cover that is easy to assemble and disassemble in order 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 that is easy to assemble and disassemble, thus solving the problem of complex structure and difficulty in installation and maintenance of rain covers.

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

[0007] A rain cover that is easy to assemble and disassemble includes a fixed bucket 1 and a swing bucket 2 hinged to the upper middle part of the fixed bucket 1 by screws. A part of the fixed bucket 1 covers the inside of the swing bucket 2. The fixed bucket 1 includes a first shell 11 and a second shell 12. The first shell 11 has a first mounting ridge 111 protruding on both sides, and the second shell 12 has a second mounting ridge 121 protruding on both sides. The first mounting ridge 111 and the second mounting ridge 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.

[0008] 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.

[0009] Preferably, the swing bucket 2 includes: a base plate 201 located on the front side, and a connecting housing 202 fixedly connected to the rear side of the base plate 201 by second screws 204; the left and right edges of the front or rear side wall of the connecting housing 202 extend outward to form connecting edges 203 for connection; a plurality of second screws 204 pass through the connecting edges 203 at even intervals and fasten the base plate 201 and the connecting housing 202 together.

[0010] 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.

[0011] Preferably, the third frame strip 93 and the fourth frame strip 94 are each provided with a strip-shaped protrusion 95 extending outward from their bottom surface, so that the third frame strip 93 and the fourth frame strip 94 have an L-shaped structure; the strip-shaped protrusion 95 overlaps the first mounting protrusion 111 and the second mounting protrusion 112 when they are connected at an angle.

[0012] 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. A detachable first connecting seat 4 is connected to the small opening 22. An auxiliary roller group 3 is installed on the first connecting seat 4. A guide channel 31 for the steel wire rope to pass through into the swing bucket 2 is formed between the auxiliary rollers of the auxiliary roller group 3. The top of the swing bucket 2 has a structure that slopes downward from the middle to both sides, so as to form a protruding hinge part 23 in the middle of the top. A detachable hinge member 5 is installed on the hinge part 23.

[0013] Preferably, the fixed barrel 1 has a first protrusion 113 and a second protrusion 114 protruding outward on both sides of the corresponding position of the hinge 23, and a space for the installation of the hinge 5 is formed between the first protrusion 113 and the second protrusion 114.

[0014] 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.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This design, through the structural integration of the fixed bucket and the swing bucket, and the hinged connection between them, reduces the number of components in the entire rain cover and simplifies the connection points, significantly reducing the complexity of installation and maintenance, alleviating the operational difficulty for workers, and also reducing the time and labor costs required for disassembly and assembly. The first and second housings, through the engagement of mounting protrusions, corresponding screw holes, and first screws, facilitate accurate alignment and detachable connection. Furthermore, the ability to disassemble and assemble the first and second housings independently eliminates the need for workers to transport and install the entire fixed bucket, facilitating subsequent maintenance and installation. The placement of the first and second mounting protrusions ensures that the swing bucket contacts the relatively small mounting protrusions rather than the entire side of the fixed bucket during swing, reducing the contact area and thus reducing wear, while also saving costs. On the other hand, it increases the contact area between the first and second housings, making the connection more robust. Multiple evenly distributed screw holes and multiple first screws provide multiple fixing points, further enhancing the stability and durability of the structure, helping to resist external impacts and vibrations, and protecting the steel wire ropes and other components inside the fixed bucket from damage.

[0017] 2. The rain cover designed in this case significantly improves the adaptability to the slight swaying of the wire rope through the hinged design of the swing bucket and the adjustability of the auxiliary roller assembly.

[0018] 3. 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 fixing tube, swing bucket, and auxiliary roller assembly. This simplifies the installation and maintenance process, and reduces operational difficulty and cost. Meanwhile, the bottom plate of the swing bucket is detachably connected to the connecting housing, facilitating installation; the design of the connecting edge increases the contact area between the connecting housing and the bottom plate, and provides a more secure fixing point for the second screw. Since the various components of the swing bucket are connected by screws, maintenance is more convenient. Each component of the swing bucket can be disassembled simply by loosening the screws, thereby reducing maintenance costs and time. Attached Figure Description

[0021] Figure 3 This is a schematic diagram of the vertical cross-sectional structure of this utility model;

[0022] Figure 4 This is a structural diagram of the present invention in actual use. Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 4 As shown, the rain cover of this case 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 covers the inside of the swing bucket 2. The fixed bucket 1 includes a first housing 11 and a second housing 12. The first housing 11 has first mounting protrusions 111 on both sides, and the second housing 12 has 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 in the plurality of screw holes. 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 plurality of first screws 13 are tightened to assemble the first housing 11 and the second housing 12 together.

[0025] As described above, this design, by structurally modifying the fixed bucket 1 and the swing bucket 2 and achieving their hinged connection, reduces the number of components in the entire rain cover and simplifies the connection points, greatly reducing the complexity of installation and maintenance, alleviating the operational difficulty for workers, and also reducing the time and labor costs required for disassembly and assembly. The first housing 11 and the second housing 12, through the cooperation of mounting protrusions, corresponding screw holes, and first screws, facilitate accurate alignment and detachable connection; moreover, the individual disassembly and assembly of the first housing 11 and the second housing 12 eliminates the need for workers to transport and install the entire fixed bucket, facilitating subsequent maintenance and installation. The placement of the first mounting protrusion 111 and the second mounting protrusion 121 ensures that the swing bucket 2 contacts the relatively small mounting protrusion rather than the entire side of the fixed passage when 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 robust. 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 impacts and vibrations, and protecting the steel wire ropes and other components inside the fixed passage from damage.

[0026] like Figure 3 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 workers to grip without hurting their hands during installation, further facilitating the operation of workers.

[0027] like Figure 1 and Figure 2As shown, the swing bucket 2 includes: a base plate 201 located on the front side, and a connecting housing 202 fixedly connected to the rear side of the base plate 201 by second screws 204; the left and right edges of the front or rear sidewall of the connecting housing 202 extend outward to form connecting edges 203 for connection; a plurality of second screws 204 are evenly spaced through the connecting edges 203 and fasten the base plate 201 and the connecting housing 202 together. Thus, through the combination of the base plate 201 and the connecting housing 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 forces and pressures, thereby improving the overall stability and safety of the rain cover. The design of the connecting edges 203 increases the contact area between the connecting housing 202 and the base plate 201 and provides a more secure fixing point for the second screws 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 simply by loosening the screws, thereby reducing maintenance costs and time costs.

[0028] 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 tube by welding.

[0029] like Figure 2As 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.

[0030] like Figure 2 and Figure 3 As shown, the swing bucket 2 has 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. A detachable first connecting seat 4 is connected to the small opening 22. An auxiliary roller assembly 3 is installed on the first connecting seat 4, and 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 top of the swing bucket 2 has a structure that slopes downwards from the middle to both sides, forming a protruding hinge portion 23 in the middle of the top. A detachable hinge member 5 is installed on the hinge portion 23. In actual use, the rain cover in this design 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 steel wire rope passes through the guide channel 31, enters the swing bucket 2, and then exits from the bottom opening of the fixed bucket 1.

[0031] As described above, the rain cover designed in this invention achieves good adaptability to the slight swaying of the wire rope through the hinged design of the swing bucket and the adjustability of the auxiliary roller assembly. The rain cover of this invention only includes a fixed bucket 1, a swing bucket 2, an auxiliary roller assembly 3, and a first connecting seat 4, 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. Unlike existing technologies where the top is flat, the inclined design of the top of the swing bucket places the hinge at the highest point of the structure. This layout helps to disperse the stress and torque generated during the swing of the bucket, thereby improving the stability and durability of the entire structure. At the same time, the protruding hinge also provides a more robust support point, enhancing the connection strength between the swing bucket and the fixed bucket.

[0032] like Figure 1 and Figure 4As 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.

[0033] like Figure 4 As shown, the fixed barrel 1 has a first protrusion 113 and a second protrusion 114 protruding outward on both sides of the corresponding position of the hinge 23, forming a space for the installation of the hinge 5 between the first protrusion 113 and the second protrusion 114. The design of the first and second protrusions in this case makes it possible to form a space for the installation of the hinge between the first and second protrusions, which facilitates positioning and installation.

[0034] 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.
