Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, and in particular to a busbar drilling device that can be adapted to multiple specifications. Background Technology

[0002] In the construction and installation of power transmission and distribution systems, busbars are key carriers for transmitting electrical energy. The quality of their connection and assembly directly affects the stability of the power supply system. In order to achieve the connection between busbars or the connection with other electrical components, construction workers often need to use special drilling equipment to process through holes of specific sizes on the busbars.

[0003] However, in actual construction sites, due to the wide variety of busbar specifications and different connection scenarios, different diameters or shapes of openings are required. This necessitates that the opening equipment must have good specification adaptability. Currently, the core opening components of existing busbar opening equipment are usually fixed directly to the main body of the equipment using relatively traditional mechanical methods. Although this connection structure can meet basic fixing requirements, it often lacks consideration for quick assembly and disassembly in its design.

[0004] However, in actual use, when operators need to replace opening components of different specifications according to the work requirements, they often need to use professional auxiliary tools and go through a series of tedious disassembly, alignment and re-tightening processes to complete the replacement. This time-consuming and laborious replacement process not only seriously restricts the work efficiency of on-site construction, but also easily affects the subsequent opening quality due to insufficient alignment accuracy during frequent disassembly and assembly operations.

[0005] Therefore, this utility model proposes a busbar opening device that can be adapted to multiple specifications to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome disassembly and assembly, low operation efficiency, and lack of effective protection and waste disposal structure when changing different specifications of busbar drilling equipment in the existing technology, this utility model aims to provide a busbar drilling equipment with improved structure that can effectively solve the above problems and is adaptable to multiple specifications.

[0007] This utility model provides a busbar drilling device adaptable to multiple specifications, including: a tool body and a drilling post; the inner wall of the tool body is provided with an installation groove, and the outer wall of the tool body is fixedly connected with a fixing ring; the drilling post is inserted into the inner wall of the installation groove.

[0009] Furthermore, the connecting ring is connected to the bottom of the outer wall of the fixing ring through the first connecting groove, so that the first connecting rod is connected to the inner wall of the first guide groove; the screw passes through the connecting ring and is connected to the inner wall of the threaded groove, thereby fixing the fixing ring and the connecting ring.

[0010] Preferably, the inner wall of the tool body is provided with a second guide groove, which is used to centrally process waste materials after the busbar is drilled.

[0011] Preferably, the tool body is further provided with a protective mechanism, the inner wall of the tool body is provided with a second guide groove, and the outer wall of the tool body is fixedly connected with a fixing rod.

[0012] Preferably, the fixing rod has a second connecting groove inside, and the protective mechanism includes a protective plate, the bottom end of which is fixedly connected to the second connecting rod.

[0013] Preferably, the second connecting rod is slidably inserted into the inner wall of the second connecting groove to connect the protective plate to the outside of the tool body.

[0014] Preferably, the protective plate is fixedly connected to both ends with guardrails, which cooperate with the protective plate to provide protection when openings are made.

[0015] Preferably, the surface of the protective plate is provided with a third guide groove, which is used for the drilling operation of the drilling post.

[0016] Preferably, there are at least two first connecting rods, which are evenly distributed at the top of the fixing ring, and the position of the first guide groove corresponds one-to-one with the position of the first connecting rod.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome disassembly and assembly and poor versatility of existing busbar drilling equipment when changing drilling components of different specifications by setting a connecting ring on the outer wall of the drilling column, cooperating with the fixing ring on the main body of the tool, utilizing the insertion and engagement of the connecting rod and the sleeve positioning of the connecting groove, and finally locking with screws. It achieves the effect of quickly and accurately changing drilling columns of different specifications, significantly improving the flexibility and efficiency of on-site operations. At the same time, the use of multi-point distributed connecting rods and guide grooves ensures the stability and torsional resistance of the connection structure.

[0018] 2. This utility model solves the problems of metal debris flying and accidentally injuring operators during hole-opening operations and the inconvenience of disassembling traditional protective covers by setting a detachable protective mechanism on the outside of the tool body, utilizing the sliding insertion and cooperation between the connecting rod at the bottom of the protective plate and the connecting groove inside the fixed rod on the main body, and setting extended guardrails at both ends of the protective plate. It achieves the effect of providing all-round safety protection, effectively isolating rotating parts and flying objects, while allowing operators to quickly disassemble the protective components for maintenance or replacement of specifications.

[0019] 3. This utility model solves the problem that metal waste generated during hole drilling is easy to accumulate inside the equipment, difficult to clean, or even jams moving parts by opening a second guide groove on the inner wall of the tool body to connect the installation groove with the external environment. It achieves the technical effect of being able to smoothly guide the waste generated by cutting to the outside of the equipment, making it easy to collect and process, keeping the inside of the equipment clean, and extending the service life of the equipment.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides a busbar opening device that can be adapted to multiple specifications, which aims to solve the structural defects of existing busbar opening devices, such as cumbersome specification changes and lack of effective protective structures.

[0024] like Figure 1 and Figure 2 As shown, a busbar drilling device adaptable to multiple specifications includes a tool body 1 and a drilling column 5 disposed inside the tool body 1. The tool body 1 serves as the supporting mounting base for the entire device, providing structural support and a foundation for power transmission. The drilling column 5 is the core component that directly performs the drilling operation. Different specifications of the column can be replaced to adapt to different drilling requirements. The inner wall of the tool body 1 has an installation groove 3 for accommodating and positioning the drilling column 5. A fixing ring 4 is fixedly connected to the outer wall of the tool body 1. The fixing ring 4 serves as a connecting intermediary component to assist in the rapid positioning and installation of the drilling column 5. To achieve rapid disassembly and assembly and stable connection of the drilling components, a connecting ring 6 is fixedly connected to the outer wall of the drilling column 5. The inner wall of the connecting ring 6 has a first connecting groove 7, and the inner wall of the connecting ring 6 also has a... The tool has a first guide groove 8, which allows for initial positioning through the cooperation of the connecting ring 6 and the fixed ring 4. The top of the fixed ring 4 is fixedly connected to a first connecting rod 9, which is inserted into the connecting ring 6 to provide radial limiting. The inner wall of the first connecting rod 9 has a threaded groove 10. The connecting ring 6 is connected to the bottom of the outer wall of the fixed ring 4 through the first connecting groove 7. This structure allows the connecting ring 6 to be fitted onto the outer wall of the fixed ring 4, while the first connecting rod 9 is connected to the inner wall of the first guide groove 8. That is, the first connecting rod 9 is inserted into the inner wall of the first guide groove 8, thereby restricting the circumferential rotation of the connecting ring 6. The screw 11 passes through the connecting ring 6 and is connected to the inner wall of the threaded groove 10. By utilizing the threaded engagement between the screw 11 and the threaded groove 10, the fixed ring 4 and the connecting ring 6 are firmly fixed together, achieving stable installation of the perforated post 5 on the tool body 1.

[0025] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that it also includes a protective mechanism 2, and the protective mechanism 2 and the aforementioned tool body 1 form a specific structural cooperation and connection relationship. Through this specific connection design, the protective components can be conveniently disassembled and maintained while ensuring operational safety.

[0026] Please refer to Figure 2 and Figure 3To facilitate the guidance and cleaning of waste materials during operation, a second guide groove 201 is provided on the inner wall of the tool body 1. The second guide groove 201 is connected to the mounting groove 3 and extends to the outside of the tool body 1. This connected design can smoothly guide the metal chips or waste generated during the cutting of the opening column 5, thereby facilitating subsequent centralized cleaning and treatment, maintaining a clean working environment, and preventing the accumulation of chips from affecting equipment operation. At the same time, in order to install the protective component, a fixing rod 202 is fixedly connected to the outer wall of the tool body 1. The fixing rod 202 serves as the supporting base for the protective component. A second connecting groove 203 is provided inside the fixing rod 202. The second connecting groove 203 is a groove structure extending in the vertical direction and is used to receive the connecting parts of the protective component.

[0027] Meanwhile, the protective mechanism 2 includes a protective plate 205, which serves as the main shielding component to block flying debris and isolate the operator from the high-speed rotating opening component. A second connecting rod 204 is fixedly connected to the bottom end of the protective plate 205. The shape and size of the second connecting rod 204 are adapted to the second connecting groove 203. In the assembled state, the second connecting rod 204 slides into the inner wall of the second connecting groove 203. This plug-in mating structure allows the protective plate 205 to be connected to the outside of the tool body 1 through the second connecting rod 204, ensuring the stability of the connection and allowing the operator to quickly pull the protective plate 205 upwards when it is necessary to change specifications or perform maintenance, greatly improving the convenience of use. In addition, to enhance the protective effect, guardrails 206 are fixedly connected to both ends of the protective plate 205. The guardrails 206 cooperate with the protective plate 205 to form a semi-enclosed protective space. The guardrails 206 extend to the side of the tool body 1, thereby providing multi-directional protective shielding when opening, further improving safety.

[0028] As a preferred embodiment, to ensure that the protective mechanism 2 provides a tight safety shield without obstructing the normal feed and retraction of the perforated column 5, a third guide groove 207 is provided on the surface of the protective plate 205. The third guide groove 207 is structurally precisely machined into a through hole or groove penetrating the thickness direction of the protective plate 205. The specific shape of the third guide groove 207 matches the cross-sectional shape of the perforated column 5, and the central axis of the third guide groove 207 is highly coincident with the working axis of the perforated column 5. When the operator drives the perforated column 5 downward to connect... When the cutting busbar is close to the cutting busbar, the perforation column 5 can pass through the internal space of the third guide groove 207 accurately and smoothly. This structural design allows the protective plate 205 to remain in place throughout the entire perforation operation. It not only continuously prevents metal debris from splashing outward and physically isolates the rotating cutting parts, but also provides a certain degree of auxiliary positioning or visual guidance for the perforation area through the edge of the third guide groove 207. This fundamentally avoids the safety hazards of having to remove the protective facilities due to the needs of the operation, reflecting the design concept of emphasizing both humanization and safety.

[0029] In another preferred embodiment, to further improve the mechanical strength and torsional resistance of the connection between the fixed ring 4 and the connecting ring 6, and to prevent the connection structure from loosening or even falling off due to high-frequency vibration or cutting resistance generated during the drilling operation, the number of first connecting rods 9 fixed to the top of the fixed ring 4 is preferably set to at least two, for example, three or four, and the first connecting rods 9 are evenly distributed along the top circumference of the fixed ring 4. Correspondingly, the number, position, and dimensional accuracy of the first guide grooves 8 opened on the inner wall of the connecting ring 6 are strictly one-to-one with the first connecting rods 9. Through this multi-point evenly distributed insertion and mating structure, when the connecting ring 6 passes through... When the first connecting groove 7 is fitted onto the outer wall of the fixed ring 4, multiple first connecting rods 9 can be simultaneously and tightly inserted into the inner wall of the corresponding first guide groove 8, thereby forming multiple mechanical interlocks in the circumferential direction. This greatly disperses the torque load transmitted to the connection point when the opening column 5 rotates. Combined with the locking force of the screw 11 passing through the connecting ring 6 and screwing into the threaded groove 10 of the first connecting rod 9, the axial clamping force generated by the threaded connection locks the fixed ring 4 and the connecting ring 6 into a rigid whole. This ensures that the entire opening assembly can maintain extremely high coaxiality and structural stability under heavy load conditions, effectively extending the service life of the equipment and ensuring the dimensional accuracy of the busbar opening.

[0030] Working Principle: When on-site operators face the need for opening holes for busbars of different sizes, they first select a hole-opening post 5 with the corresponding diameter from the spare parts warehouse according to the process standards. Then, the operator moves the selected hole-opening post 5 to the tool body 1 and aligns the tail end of the post 5 with the mounting groove 3 on the inner wall of the tool body 1 for initial insertion and assembly. During this assembly process, the operator controls the connecting ring 6, which is fixedly connected to the outer wall of the hole-opening post 5, to gradually move downwards, bringing it closer to and fitting against the fixing ring 4 fixedly connected to the outer wall of the tool body 1. To ensure the accuracy of the connection, the operator meticulously adjusts the circumferential angle of the connecting ring 6 until the first connecting groove 7 on the inner wall of the connecting ring 6 and the bottom contour of the outer wall of the fixing ring 4 are completely coaxially aligned. Simultaneously, the operator ensures that the first guide groove 8 on the inner wall of the connecting ring 6 and the first connecting rod 9 fixedly connected to the top of the fixing ring 4 are precisely aligned in position. After completing the above alignment operation, the operator applies downward pressure along the axial direction, driving the connecting ring 6 to continue downwards, allowing the connecting ring 6 to pass through the first... A connecting groove 7 tightly fits onto the outer wall of the fixing ring 4. Simultaneously, the first connecting rod 9 slides into the inner wall of the first guide groove 8. The solid structure of the first connecting rod 9 effectively restricts any circumferential rotation of the connecting ring 6 relative to the fixing ring 4 by blocking the side wall of the first guide groove 8, thus achieving stable positioning of the perforated post 5 in the circumferential direction. Next, the operator takes a screw 11, passes it through the pre-drilled hole in the side wall of the connecting ring 6, and uses a matching screwdriver. The screw 11 is screwed into the threaded groove 10 opened on the inner wall of the first connecting rod 9. As the screw 11 is tightened, the head of the screw 11 presses against the outer wall of the connecting ring 6. The strong axial locking force generated by the threaded pair firmly fixes the connecting ring 6 and the fixing ring 4 into a rigid whole, thereby completing the quick and firm installation of the hole post 5 on the tool body 1. This structural design cleverly avoids the cumbersome disassembly process when changing tools in traditional equipment, greatly improving the efficiency of on-site operation and the versatility of the equipment. Before commencing busbar drilling operations after the installation and commissioning of the perforated column 5, a protective mechanism 2 must be correctly installed to create a safe working environment and prevent metal cutting debris from causing personal injury to the operators. The operator holds the protective plate 205 in the protective mechanism 2 and aligns the second connecting rod 204, which is fixedly connected to the bottom of the protective plate 205, with the second connecting groove 203 inside the fixing rod 202 on the outer wall of the tool body 1. The operator maintains the second connecting rod 204 vertically downward and applies external force to push the second connecting rod 204 downward along the guide direction of the second connecting groove 203 until... The second connecting rod 204 is fully and tightly inserted into the inner wall of the second connecting groove 203. Relying on the long-distance sliding fit between the second connecting rod 204 and the second connecting groove 203, the protective plate 205 is stably and reliably suspended and fixed to the outside of the tool body 1. At this time, the guardrails 206 fixed at both ends of the protective plate 205 extend rearward to the side of the tool body 1. The guardrails 206 and the protective plate 205 together form a semi-enclosed protective barrier for the opening area. Furthermore, the third guide groove 207 opened on the surface of the protective plate 205 is precisely aligned with the feed path of the opening post 5. When started... When the external power source drives the equipment to start working, the perforating column 5 rotates at high speed under the driving force and begins to feed downward. The front end of the perforating column 5 smoothly passes through the third guide groove 207 on the protective plate 205 and contacts the busbar surface to perform cutting operations. During the intense cutting process, the sharp metal chips and high-temperature slag generated are effectively blocked by the front protective plate 205 and the side rails 206, and are confined within the protective area to fall down, preventing them from splashing towards the direction where the operator is standing, thus playing a crucial safety isolation role. At the same time, as the perforation operation continues, the chips fall into the mounting groove 3. Waste material in the tool body 1 will naturally converge and flow into the second guide groove 201 opened on the inner wall of the tool body 1 under the combined action of gravity and centrifugal cutting force. Since the second guide groove 201 connects the mounting groove 3 and the external space of the tool body 1 in terms of structure, the waste material can be smoothly discharged to the outside of the equipment along the inclined or guide path of the second guide groove 201. This makes it convenient for operators to collect and clean the equipment from the outside. This design not only keeps the inside of the equipment clean, but also avoids equipment failure caused by the accumulation of waste material jamming moving parts, thus achieving the dual effects of safety protection and efficient waste discharge.
