Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a fixed-length cutting device for tubular busbars. Background Technology

[0002] Tubular busbars are a type of high-efficiency power transmission device for carrying high-voltage current. Compared with traditional rectangular busbars, they have many advantages, such as high current carrying capacity per unit cross-section, good skin effect, good heat dissipation, large allowable stress, large span, high mechanical strength, strong electrical insulation performance, high stability of main insulation materials, and reasonable insulation process. With the rapid and steady growth of the national economy, social electricity consumption has increased dramatically, leading to a continuous increase in the capacity of main transformers in substations. Consequently, the rated current on the low-voltage outgoing side of the main transformer has also increased. Therefore, the power sector is increasingly using tubular busbars. However, in current technology, the fixing of tubular busbars is mostly done manually or with simple fixation. This results in problems such as uneven cut surfaces due to vibration during the cutting process, and the potential for injury to workers. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where tubular busbars are mostly fixed manually or simply, resulting in uneven cut surfaces and potential injuries to workers due to vibration during the cutting process. Therefore, a tubular busbar fixed-length cutting device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tubular busbar fixed-length cutting device includes a table and a cutting component, the cutting component being located at the upper end of the table. The cutting device also includes a limiting mechanism located on the table, the limiting mechanism being used to limit the tubular busbar.

[0006] As a preferred embodiment of this utility model, the limiting mechanism includes: two conveying wheels, a motor, an L-shaped rod, a drive rod, a first V-shaped rod, a sliding sleeve, a second V-shaped rod, two support columns, a propulsion wheel, and a power assembly;

[0007] One of the conveyor wheels is rotatably connected to the upper end of the table. The output shaft of the motor rotates through the table and is fixedly connected to the other conveyor wheel. One end of the L-shaped rod rotates through the table. One end of the drive rod is rotatably connected to the other end of the L-shaped rod. Both support columns are fixedly connected to the table. The corner of the first V-shaped rod and one end of the second V-shaped rod are respectively rotatably fitted onto the two support columns. The sliding sleeve is slidably fitted onto one end of the second V-shaped rod. The two ends of the first V-shaped rod are respectively rotatably connected to the other end of the drive rod and one side of the sliding sleeve. The propulsion wheel is vertically rotatably connected to the other end of the second V-shaped rod.

[0008] Furthermore, by placing the tubular busbar between two conveyor wheels and a drive wheel, and then rotating the L-shaped rod around the penetration point, the drive rod pulls the first V-shaped rod. Simultaneously, the two ends of the drive rod rotate around the other end of the L-shaped rod and one end of the first V-shaped rod, respectively. The corner of the first V-shaped rod and the other end of the first V-shaped rod rotate around one of the support columns and the sliding sleeve, respectively. The rotational force of the first V-shaped rod causes the sliding sleeve to slide along one end of the second V-shaped rod and causes the second V-shaped rod to rotate around the other support column. This allows the drive wheel to advance towards the two conveyor wheels to limit the tubular busbar. Then, the motor is started, and the output shaft of the motor drives the other conveyor wheel to rotate, thus conveying the limited tubular busbar.

[0009] As a preferred embodiment of this utility model, the power assembly includes: a gear, a rack, a hydraulic rod, a fixing block, and a slide groove;

[0010] The fixed block is fixedly connected to the bottom of the table body. The two ends of the hydraulic rod are fixedly connected to the fixed block and one end of the rack, respectively. One end of the L-shaped rod rotates through the table body and is fixedly connected to the gear. The rack meshes with the gear. The slide groove is opened at the bottom of the table body, and the protruding end of the rack slides in the slide groove.

[0011] Furthermore, by activating the hydraulic rod, the hydraulic rod extends and advances the rack, while the protruding end of the rack slides in the groove, thereby using the meshing force between the rack and the gear to make the gear rotate, thus providing power for the rotation of the gear.

[0012] As a preferred embodiment of this utility model, the table body is provided with a cut hole and a scale groove, with the scale groove located on one side of the cut hole.

[0013] Furthermore, when cutting the tubular busbar, the cutting blade of the cutting component matches the cutting hole, and when transporting the tubular busbar, the required length can be determined automatically according to the scale groove for cutting.

[0014] As a preferred embodiment of this utility model, dust covers are fixedly fitted onto both the limiting mechanism and the power component, and the dust covers are bolted to the table body.

[0015] Furthermore, by covering the limit mechanism and power component with dust covers, it is possible to effectively prevent a large amount of dust from affecting the limit mechanism and power component.

[0016] Beneficial effects:

[0017] 1. By placing the tubular busbar between two conveyor wheels and a drive wheel, the L-shaped rod rotates around the penetration point, thereby pulling the first V-shaped rod using the drive rod. Simultaneously, the two ends of the drive rod rotate around the other end of the L-shaped rod and one end of the first V-shaped rod, respectively. The corner of the first V-shaped rod and the other end of the first V-shaped rod rotate around one of the support columns and the sliding sleeve, respectively. The rotational force of the first V-shaped rod causes the sliding sleeve to slide along one end of the second V-shaped rod, causing the second V-shaped rod to rotate around the other support column. This allows the drive wheel to advance towards the two conveyor wheels, limiting the tubular busbar. Then, the motor is started, and the output shaft of the motor drives the other conveyor wheel to rotate, thus conveying the limited tubular busbar.

[0018] 2. By activating the hydraulic rod, the hydraulic rod extends and advances the rack. At the same time, the protruding end of the rack slides in the groove, thereby using the meshing force between the rack and the gear to make the gear rotate, thus providing power for the rotation of the gear.

[0019] In this invention, the cooperation between the limiting mechanism and the power component can effectively prevent uneven cutting surfaces caused by vibration of the tubular busbar during the cutting process, and can also prevent workers from being cut. This can effectively improve cutting efficiency and reduce safety hazards. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 A tubular busbar fixed-length cutting device includes a table body 1 and a cutting component 2. The cutting component 2 is located at the upper end of the table body 1. The cutting device also includes a limiting mechanism located on the table body 1. The limiting mechanism is used to limit the tubular busbar.

[0027] In this utility model, the limiting mechanism includes: two conveying wheels 6, a motor 7, an L-shaped rod 8, a drive rod 9, a first V-shaped rod 10, a sliding sleeve 11, a second V-shaped rod 12, two support columns 13, a propulsion wheel 14, and a power assembly;

[0028] like Figure 3 As shown, one conveyor wheel 6 is rotatably connected to the upper end of the table body 1. The output shaft of the motor 7 rotatably passes through the table body 1 and is fixedly connected to the other conveyor wheel 6. One end of the L-shaped rod 8 rotatably passes through the table body 1, and one end of the drive rod 9 rotatably connects to the other end of the L-shaped rod 8. Both support columns 13 are fixedly connected to the table body 1. The corner of the first V-shaped rod 10 and one end of the second V-shaped rod 12 are respectively rotatably sleeved on the two support columns 13. The sliding sleeve 11 is slidably sleeved on one end of the second V-shaped rod 12. The two ends of the first V-shaped rod 10 are respectively rotatably connected to the other end of the drive rod 9 and one side of the sliding sleeve 11. The push wheel 14 is vertically rotatably connected to the other end of the second V-shaped rod 12. By placing the tubular busbar between the two conveyor wheels 6 and the push wheel 14, then... The L-shaped rod 8 rotates around the penetration point, and the driving rod 9 pulls the first V-shaped rod 10. At the same time, the two ends of the driving rod 9 rotate around the other end of the L-shaped rod 8 and the first V-shaped rod 10, respectively. The corner of the first V-shaped rod 10 and the other end of the first V-shaped rod 10 rotate around one of the support columns 13 and the sliding sleeve 11, respectively. The rotational force of the first V-shaped rod 10 causes the sliding sleeve 11 to slide along one end of the second V-shaped rod 12 and causes the second V-shaped rod 12 to rotate around the other support column 13. This allows the push wheel 14 to advance towards the two conveying wheels 6 to limit the tubular busbar. Then, the motor 7 is started, and the output shaft of the motor 7 drives the other conveying wheel 6 to rotate, thus conveying the limited tubular busbar.

[0029] In this utility model, the power assembly includes: a gear 15, a rack 16, a hydraulic rod 17, a fixing block 18, and a slide groove 19;

[0030] like Figure 4As shown, the fixing block 18 is fixedly connected to the bottom end of the table body 1. The two ends of the hydraulic rod 17 are fixedly connected to the fixing block 18 and one end of the rack 16, respectively. One end of the L-shaped rod 8 rotates through the table body 1 and is fixedly connected to the gear 15. The rack 16 meshes with the gear 15. The slide groove 19 is opened at the bottom end of the table body 1. The protruding end of the rack 16 slides in the slide groove 19. By activating the hydraulic rod 17, the hydraulic rod 17 extends and pushes the rack 16. At the same time, the protruding end of the rack 16 slides in the slide groove 19. Then, the meshing force between the rack 16 and the gear 15 is used to make the gear 15 rotate, thereby providing power for the rotation of the gear 15.

[0031] like Figure 1 As shown, the table body 1 has a cutting hole 5 and a scale groove 3. The scale groove 3 is located on one side of the cutting hole 5. When cutting the tubular busbar, the cutting blade of the cutting component 2 fits into the cutting hole 5. At the same time, when transporting the tubular busbar, the required length can be determined by the scale groove 3 for cutting.

[0032] like Figure 1 and Figure 2 As shown, dust covers 4 are fixedly fitted on both the limiting mechanism and the power component. The dust covers 4 are bolted to the table body 1. By fitting the dust covers 4 onto the limiting mechanism and the power component, a large amount of dust can be effectively prevented from affecting the limiting mechanism and the power component.

[0033] It should be noted that the specific models of cutting component 2, motor 7, and hydraulic rod 17 used can be selected by those skilled in the art. Furthermore, the cutting component 2, motor 7, and hydraulic rod 17 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0034] The working principle of this utility model:

[0035] First, the tubular busbar is placed between the two conveying wheels 6 and the pushing wheel 14. Then, the hydraulic rod 17 is activated, extending and pushing the rack 16. Simultaneously, the protruding end of the rack 16 slides within the groove 19, thereby utilizing the meshing force between the rack 16 and the gear 15 to rotate the gear 15. This rotational force of the gear 15 causes the L-shaped rod 8 to rotate around the gear 15 as its center. This, in turn, uses the drive rod 9 to pull the first V-shaped rod 10. At the same time, the two ends of the drive rod 9 rotate around the other end of the L-shaped rod 8 and the first V-shaped rod 10, respectively. The corner of the first V-shaped rod 10 and the other end of the first V-shaped rod 10 are supported by one of the support columns 1. Rotating with the sliding sleeve 11 as the center, the rotational force of the first V-shaped rod 10 causes the sliding sleeve 11 to slide along one end of the second V-shaped rod 12 and rotate the second V-shaped rod 12 with the other support column 13 as the center. This allows the push wheel 14 to advance towards the two conveying wheels 6 to limit the tubular busbar. Then, the motor 7 is started, and the output shaft of the motor 7 drives the other conveying wheel 6 to rotate, thus conveying the tubular busbar after it has been limited. At the same time, the required length can be determined by the scale groove 3 during conveying. Then, the cutting component 2 is started, and the cutting blade of the cutting component 2 passes through the cutting hole 5, thus cutting the tubular busbar of the determined length.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
