Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically to an anti-loosening aluminum profile frame for an energy storage cabinet. Background Technology

[0002] Energy storage cabinets are widely used in the new energy field to house and protect battery modules. Their frames are typically constructed from aluminum profiles connected by angle brackets and bolts, or welded from steel. Once the battery packs are installed inside, the overall weight is considerable, and during hoisting, the aluminum profile frame may bend at localized stress points, severely impacting its usability. Existing aluminum profile frames suffer from the following problems:

[0003] 1. Insufficient hoisting strength: The cabinet needs to be hoisted during transportation and installation. The hoisting point strength of traditional aluminum profile frames is limited. Under heavy load hoisting or long-term vibration, the area around the hoisting holes is prone to deformation or even tearing, which poses a safety hazard.

[0004] 2. Connection points are prone to loosening: Bolts and nuts used to connect corner brackets and profiles are subject to long-term vibration and impact during equipment operation and transportation, which can easily cause them to loosen or even fall off, resulting in a decrease in the stability of the frame structure and affecting the overall rigidity and safety of the cabinet.

[0005] 3. Insufficient anti-loosening measures: Common anti-loosening methods such as anti-loosening washers or double nuts have limited effectiveness in long-term, strong vibration environments. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an anti-loosening aluminum profile frame for energy storage cabinets. The frame significantly improves the strength of the lifting points through built-in reinforcing ribs and effectively prevents the connecting bolts and nuts from loosening by using a unique bolt limiting device. The overall structure is stable and reliable.

[0007] To achieve the above objectives, the technical solution of this utility model is to design an anti-loosening aluminum profile frame for energy storage cabinets, including frame components, corner brackets, and lifting lugs. The corners of the frame components are reinforced and connected by corner brackets, and the corner brackets are fastened to the frame components by fixing bolts and nuts. Symmetrical through-holes are provided on the top crossbeam of the frame components. Connecting components are provided on the lifting lugs, and these connecting components mate with the lifting holes. Each connecting component includes a matching lifting bolt and a lifting nut. A reinforcing groove is formed along the length of the aluminum profile inside the frame components, and a reinforcing rib with a matching shape is embedded in the reinforcing groove. The reinforcing rib is preferably made of high-strength steel. The reinforcing rib, embedded in the reinforcing groove inside the aluminum profile, effectively improves the overall structural strength of the aluminum profile and prevents localized bending deformation during lifting.

[0008] The connecting assembly also includes a tapered washer fitted onto the lifting bolt and located on the top crossbeam of the frame assembly. The tapered washer prevents the lifting bolt and lifting nut from loosening during lifting.

[0009] It also includes a bolt limiting device, which is fastened to the fixing bolt and the fixing nut. The bolt limiting device includes a U-shaped first limiting plate and a U-shaped second limiting plate. The U-shaped opening ends of the first limiting plate and the second limiting plate are provided with locking elements. The non-contact surfaces of the first limiting plate and the second limiting plate are provided with a first limiting groove that matches the contour of the fixing bolt head and the fixing nut. The first limiting plate and the second limiting plate are respectively fitted onto the fixing bolt head and the fixing nut.

[0010] Both the first and second limiting plates have mating second limiting grooves at their U-shaped opening edges. These second limiting grooves match the contours of the fixing bolt head and the fixing nut, and their central axes do not intersect. The second limiting grooves on the first and second limiting plates fit together to form a slot that matches the contours of the fixing bolt head and the fixing nut, thus restricting the rotation of the fixing bolt and the fixing nut.

[0011] The locking components consist of a locking block and a locking groove respectively disposed on the contact surfaces of the first and second limiting plates. The locking block forms a certain angle with the contact surface, and the shapes of the locking block and the locking groove match each other. During installation, the locking block is flattened to be flush with the contact surface and embedded in the locking groove, thereby preventing the first and second limiting plates from separating due to vibration or other reasons, which would affect the use.

[0012] It also includes a fastening device, which includes a fastening screw and a fastening ring. The fastening ring has threaded holes at both ends, which respectively cooperate with one end of the fastening screw and the lifting bolt. The other end of the fastening screw passes through the bottom crossbeam of the frame assembly, and its end is fastened with a fastening nut.

[0013] A tapered washer is provided between the fastening nut and the bottom surface of the bottom crossbeam of the frame assembly. The tapered washer prevents the fastening nut from loosening during hoisting.

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

[0015] 1. By embedding reinforcing ribs within the aluminum profiles and ensuring that the lifting holes pass through these ribs, the lifting stress point is transferred from the softer aluminum profiles to the high-strength reinforcing ribs. This significantly improves the lifting load-bearing capacity, resistance to deformation and tearing, and ensures lifting safety. The embedded reinforcing ribs in the aluminum profiles result in a frame structure that is stronger than a frame structure made solely of aluminum profiles, yet lighter than a frame structure made solely of steel. Furthermore, the reinforcing ribs can be embedded only in the supporting columns as needed.

[0016] 2. The bolt limiting device physically locks the relative positions of the bolt head and nut, completely eliminating the phenomenon of the fixing bolt and nut rotating and loosening due to vibration, and greatly improving the long-term stability of the frame corner connection.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] according to Figure 1 , 2As shown, this utility model is an anti-loosening aluminum profile frame for an energy storage cabinet, including a frame assembly 1, corner brackets 2, and lifting lugs 3. The corners of the frame assembly 1 are reinforced by the corner brackets 2. The corner brackets 2 and the frame assembly 1 are fastened together by fixing bolts 4 and fixing nuts 5. The top crossbeam of the frame assembly 1 has symmetrical through-holes 6. The lifting lugs 3 are provided with connecting components 7. The connecting components 7 cooperate with the lifting holes 6. The connecting components 7 include mutually cooperating lifting bolts 71 and lifting nuts 72. The aluminum profile of the frame assembly 1 has a reinforcing groove 11 opened along the length direction. The reinforcing groove 11 is embedded with reinforcing ribs 12 whose shape matches the reinforcing groove 11.

[0026] During installation, the reinforcing rib 12 is inserted into the reinforcing groove 11 inside the aluminum profile of the frame component 1, which mainly supports the load. Then, the corner bracket 2 is placed into the corner of the frame, and the fixing bolts 4 and fixing nuts 5 are used to initially tighten it to the profiles on both sides. The entire frame assembly is completed. During hoisting, the hoisting bolts 71 on the lifting lugs 3 need to be inserted into the symmetrically arranged through hoisting holes 6 on the top crossbeam of the frame component 1. At this time, the reinforcing rib 12 is also penetrated by the hoisting bolts 71. Then, the hoisting nuts 72 are screwed into the hoisting bolts 71, thereby fixing the lifting lugs 3 to the top crossbeam of the frame component 1. During hoisting, the force on the lifting lugs 3 is transmitted to the columns of the frame component 1 along the hoisting bolts 71. The columns are connected by fixing bolts 4, fixing nuts 5 and corner brackets 2 to form a whole. The reinforcing rib 12 is inserted into the aluminum profile of the frame component 1, thereby further strengthening the strength of the entire frame component 1.

[0027] according to Figure 1 As shown, the connecting assembly 7 also includes a tapered washer 73, which is fitted onto the lifting bolt 71 and located on the top crossbeam of the frame assembly 1.

[0028] The tapered washer 73 is located between the lifting lug 3 and the upper surface of the top crossbeam of the frame. When the lifting nut 72 is tightened, the tapered washer 73 is compressed, and its tapered surface generates a radial expansion force, embedding itself into the surface of the connector and the bolt threads, forming a strong anti-loosening resistance. The tapered washer 73 can also be placed between the lifting nut 72 and the lower surface of the top crossbeam of the frame, serving the same anti-loosening function.

[0029] according to Figure 3-5As shown, it also includes a bolt limiting device, which is fastened to the fixing bolt 4 and the fixing nut 5. The bolt limiting device includes a U-shaped first limiting plate 81 and a U-shaped second limiting plate 82. The U-shaped opening ends of the first limiting plate 81 and the second limiting plate 82 are provided with locking elements 83. The non-contact surfaces of the first limiting plate 81 and the second limiting plate 82 are provided with first limiting grooves 84 that match the contours of the head of the fixing bolt 4 and the fixing nut 5. The first limiting plate 81 and the second limiting plate 82 are respectively fitted onto the head of the fixing bolt 4 and the fixing nut 5.

[0030] The locking component 83 consists of a locking block 831 and a locking groove 832 respectively disposed on the contact surfaces of the first limiting plate 81 and the second limiting plate 82. The locking block 831 forms a certain angle with the contact surface, and the shape of the locking block 831 and the shape of the locking groove 832 match each other.

[0031] Before the first limiting plate 81 and the second limiting plate 82 are installed, the locking block 831 of the locking member 83 forms a certain angle with the first limiting plate 81 and the second limiting plate 82. During installation, the first limiting plate 81 and the second limiting plate 82 are placed on the column of the frame assembly 1 and the corner bracket 2, and the first limiting groove 84 is fitted onto the head of the fixing bolt 4 and the fixing nut 5. Then, the locking block 831 on the first limiting plate 81 and the second limiting plate 82 is flattened with a tool so that it is completely embedded in the groove 832, thereby preventing the first limiting plate 81 and the second limiting plate 82 from separating.

[0032] according to Figure 5 As shown, the first limiting plate 81 and the second limiting plate 82 are both provided with a second limiting groove 85 that matches each other at the edge of the U-shaped opening. The second limiting groove 85 matches the outline of the head of the fixing bolt 4 and the fixing nut 5. The central axes of the first limiting groove 84 and the second limiting groove 85 do not intersect.

[0033] After the frame is installed, when all four sides of the same column have fixing bolts 4 and fixing nuts 5, it is necessary to use a first limiting plate 81 and a second limiting plate 82, which have both a first limiting groove 84 and a second limiting groove 85. The usage steps are the same as described above, except that after the first limiting plate 81 and the second limiting plate 82 are joined together, the second limiting groove 85 at the interface will precisely lock and fix the fixing bolts 4 and fixing nuts 5 on the other two sides. At this time, it should be noted that the central axes of the first limiting groove 84 and the second limiting groove 85 do not intersect. That is to say, after the fixing bolts 4 are inserted, there will be no obstruction inside the column.

[0034] according to Figure 6As shown, it also includes a fastening device, which includes a fastening screw 91 and a fastening ring 92. The fastening ring 92 has threaded holes 93 at both ends. The threaded holes 93 are respectively engaged with one end of the fastening screw 91 and the lifting bolt 71. The other end of the fastening screw 91 passes through the bottom crossbeam of the frame assembly 1, and its end is fastened with a fastening nut 94.

[0035] A tapered washer 73 is provided between the fastening nut 94 and the bottom surface of the bottom crossbeam of the frame assembly 1.

[0036] During hoisting, insert the fastening screw 91 into the bottom crossbeam of the frame assembly 1, then fit the threaded holes 93 at both ends of the fastening ring 92 onto one end of the fastening screw 91 and the hoisting bolt 71 respectively. Then rotate the fastening ring 92 so that the fastening screw 91 and the hoisting bolt 71 are simultaneously screwed into the threaded holes 93 at both ends of the fastening ring 92. Then fit the tapered washer 73 onto the fastening screw 91 and tighten it with the fastening screw 91.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
