Description

Technical Field

[0001] This utility model belongs to the field of smart grid wiring technology, and in particular relates to an auxiliary frame for smart grid wiring. Background Technology

[0002] In the construction and operation of smart grids, cable wiring is a key link to ensure the stable operation of the power grid. As the core component for cable support and positioning, the performance of the wiring auxiliary frame directly affects the wiring efficiency, construction safety and long-term reliability of the power grid. As smart grids develop towards distributed, highly integrated and refined directions, traditional cable wiring auxiliary frames have gradually exposed problems such as single function, insufficient adaptability and prominent safety hazards, making it difficult to meet the comprehensive needs of modern power grid wiring operations.

[0003] Existing auxiliary frames can only fix cables, making it difficult to strip cables as needed. Cable stripping mainly relies on workers using utility knives and wire strippers, which poses serious safety risks and operational defects. Manual operation makes it difficult to accurately control the depth and force of the blade, which can easily lead to over-stripping and damage to the conductor, or under-stripping and insulation residue. The former will reduce the conductivity of the cable, while the latter may cause safety accidents such as overheating and short circuits at the connection point. Therefore, an auxiliary frame for smart grid wiring is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an auxiliary frame for smart grid wiring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary frame for smart grid wiring includes a base plate, a connection box connected to the top of the base plate, a clamping assembly connected to one end of the connection box, and a cutting assembly connected to the top of the connection box.

[0007] The cutting assembly includes a motor, the output end of which is connected to a lead screw. A movable frame is threaded to the outside of the lead screw. A limit frame is welded to the top of the movable frame. A two-section electric telescopic rod is connected through the outside of the limit frame. One end of one section of the two-section electric telescopic rod is connected to a limit plate, and one end of the other section of the two-section electric telescopic rod is connected to a cutting blade.

[0008] In a further technical solution, the number of the two-section electric telescopic rod and the limiting plate are three in total. The inner side of the limiting plate is connected to a movable clamping plate, and the cutting blade is connected through the limiting plate and the movable clamping plate.

[0009] In a further technical solution, the clamping assembly includes a knob, a bidirectional threaded rod connected to one side of the knob, a movable block connected to the outer side of the bidirectional threaded rod via a thread, a fixed frame connected to the top of the movable block, a hollow rod connected to the inner side of the fixed frame, a spring connected to the inner side of the hollow rod, a damper connected to one end of the hollow rod, a connecting rod connected to one end of the spring, and a fixed plate connected to one end of the connecting rod.

[0010] In a further technical solution, the threads at both ends of the bidirectional threaded rod are in opposite directions, and there are two fixed frames and two movable blocks. The two movable blocks are respectively connected to both ends of the bidirectional threaded rod by threads.

[0011] In a further technical solution, the damper is located inside the spring, the connecting rod is located inside the hollow rod, and there are four connecting rods, four hollow rods, and four fixing plates. The inner sides of the four fixing plates are all connected to rubber plates.

[0012] In a further technical solution, displacement sensors are embedded on one side of the movable frame and at one end of the two-section electric telescopic rod. A controller is connected to the top of the connecting box, and the controller is wirelessly connected to the two-section electric telescopic rod, the motor, and the displacement sensors.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a motor-driven lead screw that smoothly moves the movable frame, while a two-section electric telescopic rod precisely controls the feed and position of the cutting blade. Workers do not need to come into close contact with the blade, fundamentally avoiding the safety risk of hand injuries from uncontrolled tools during traditional manual stripping. This significantly reduces the incidence of personal injury accidents during wiring operations. A displacement sensor monitors the extension distance of the two-section electric telescopic rod and the movement position of the movable frame in real time, and the data is synchronously transmitted to the controller. The controller precisely adjusts the cutting depth and stripping length of the cutting blade, avoiding over-stripping that could cause conductor breakage or scratches, ensuring the conductivity of the cable, and preventing under-stripping that could leave residual insulation, thus eliminating potential safety hazards to the power grid such as overheating and short circuits at subsequent wiring points.

[0015] In this invention, four fixing plates are connected to rubber plates on their inner sides, and the fixing plates are connected to springs and dampers inside the hollow rods via connecting rods. The springs can automatically adjust the clamping force according to the cable diameter, and the dampers buffer the impact force during clamping, thereby avoiding damage to the cable sheath from hard clamping. In the cutting assembly, three two-stage electric telescopic rods can adjust the radial position of the cutting blades respectively, further adapting to different cable sheath thicknesses.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-3 As shown, this utility model embodiment provides an auxiliary frame for smart grid wiring, including a base plate 1, a connection box 2 connected to the top of the base plate 1, a clamping component 3 connected to one end of the connection box 2, and a cutting component 4 connected to the top of the connection box 2.

[0024] The cutting assembly 4 includes a motor 401, the output end of which is connected to a lead screw 402. A movable frame 403 is threadedly connected to the outside of the lead screw 402. A limit frame 404 is welded to the top of the movable frame 403. A two-section electric telescopic rod 405 is connected through the outside of the limit frame 404. One end of one section of the two-section electric telescopic rod 405 is connected to a limit plate 407, and one end of the other section of the two-section electric telescopic rod 405 is connected to a cutting blade 406.

[0025] In this embodiment, the controller 5 can control the extension of the two-section electric telescopic rod 405. The two-section electric telescopic rod 405 is a multi-section electric push rod consisting of a first-stage push mechanism and a second-stage push mechanism. A sliding plate is slidably installed inside the housing, and a first-stage push rod that can extend out of the housing is fixed at the front end of the sliding plate. The first-stage push rod is driven to extend by the first-stage push mechanism. The first-stage push rod can drive the limiting plate 407 and the movable clamping plate 6 to clamp the cable. A second-stage push rod that can extend out of the first-stage push rod is slidably installed inside the first-stage push rod. When one end of the cable is fixed between the movable clamping plates 6, the second-stage push rod... The first push mechanism can drive the second-stage push rod to extend, thereby driving the cutting blade 406 to extend. The extension length of the cutting blade 406 can be precisely controlled by the displacement sensor 8 and the controller 5 to adapt to cables with different outer sheath thicknesses. The motor 401 is started, which drives the lead screw 402 to rotate. Since the outer side of the lead screw 402 is connected to the movable frame 403 by a thread, the movable frame 403 and the limit frame 404 can move axially along the lead screw 402. The cutting blade 406 can cut open the cable sheath during the movement to complete the cable stripping work.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, specifically, there are three two-section electric telescopic rods 405 and three limiting plates 407. The inner side of the limiting plate 407 is connected to a movable clamping plate 6. The cutting blade 406 is connected through the limiting plate 407 and the movable clamping plate 6.

[0027] The clamping assembly 3 includes a knob 301, a bidirectional threaded rod 302 connected to one side of the knob 301, a movable block 303 connected to the outer side of the bidirectional threaded rod 302 by a thread, a fixed frame 304 connected to the top of the movable block 303, a hollow rod 305 connected to the inner side of the fixed frame 304, a spring 306 connected to the inner side of the hollow rod 305, a damper 307 connected to one end of the hollow rod 305, a connecting rod 308 connected to one end of the spring 306, and a fixed plate 309 connected to one end of the connecting rod 308.

[0028] The two ends of the bidirectional threaded rod 302 have opposite thread directions. There are two fixed frames 304 and two movable blocks 303. The two movable blocks 303 are respectively connected to the two ends of the bidirectional threaded rod 302 by threads.

[0029] The damper 307 is located inside the spring 306, the connecting rod 308 is located inside the hollow rod 305, and there are four connecting rods 308, four hollow rods 305 and four fixing plates 309. The inner sides of the four fixing plates 309 are all connected to rubber plates 7.

[0030] Displacement sensors 8 are embedded on one side of the movable frame 403 and one end of the two-section electric telescopic rod 405. A controller 5 is connected to the top of the connecting box 2. The controller 5 is wirelessly connected to the two-section electric telescopic rod 405, the motor 401 and the displacement sensors 8.

[0031] In this embodiment, the cable is placed between two fixed frames 304. By rotating the knob 301, the bidirectional threaded rod 302 can be rotated. Since the threads of the bidirectional threaded rod 302 are opposite and connected to the two movable blocks 303 by threads, the two fixed frames 304 can be moved towards each other. The cable can then be fixed by the four rubber plates 7. The clamping force can be automatically adjusted according to the cable diameter by the spring 306 set in the connecting rod 308 and the hollow rod 305. The damper 307 buffers the impact force during clamping, thereby avoiding damage to the cable outer sheath by hard clamping.

[0032] The working principle of this utility model is as follows: First, the cable is placed between two fixed frames 304. By rotating the knob 301, the bidirectional threaded rod 302 can be rotated. Since the threads of the bidirectional threaded rod 302 are opposite and connected to the two movable blocks 303 by threads, the two fixed frames 304 can be moved towards each other. Then, the cable can be fixed by the four rubber plates 7. Then, the controller 5 can control the extension of the two-section electric telescopic rod 405. The two-section electric telescopic rod 405 is a multi-section electric push rod with a first-stage push mechanism and a second-stage push mechanism. A sliding plate is slidably installed inside the housing. A first-stage push rod that can extend out of the housing is fixed at the front end of the sliding plate. The first-stage push rod is driven to extend by the first-stage push mechanism. The first-stage push rod can drive the limiting plate. The cable is clamped by clamps 407 and movable clamp 6. A secondary push rod that can extend from the primary push rod is slidably installed inside the primary push rod. When one end of the cable is fixed between the movable clamps 6, the secondary push rod can be extended by the second push mechanism, thereby causing the cutting blade 406 to extend. The extension length of the cutting blade 406 can be precisely controlled by the displacement sensor 8 and the controller 5 to adapt to cables with different sheath thicknesses. Finally, the motor 401 is started, which drives the lead screw 402 to rotate. Since the outer side of the lead screw 402 is connected to the movable frame 403 by threads, the movable frame 403 and the limit frame 404 can move axially along the lead screw 402. The cutting blade 406 can cut the cable sheath during the movement to complete the cable stripping work.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
