Description
Technical Field
[0001] This utility model relates to the field of power test and comprehensive testing technology, specifically a power test and comprehensive testing workbench. Background Technology
[0002] Comprehensive power testing is a crucial step in ensuring the safe and stable operation of power equipment. As an important component of preventative testing in power systems, its test results directly impact equipment condition assessment and maintenance decisions. These tests typically cover multiple specialized areas, including insulation resistance testing, dielectric loss measurement, loop resistance detection, AC / DC withstand voltage testing, partial discharge detection, and circuit breaker mechanical characteristic testing. They require testing equipment with high-precision measurement capabilities and stringent electrical safety performance. Traditionally, operators frequently need to change test cables and adjust instrument layouts during testing.
[0003] In traditional power testing benches, cable management typically uses fixed cable trays or simple straps, which makes the cable bundles prone to tangling and pulling during testing, resulting in messy cable bundles on the bench. This not only affects testing efficiency but may also lead to accidental contact or short circuit risks, impacting operational efficiency and posing safety hazards. In addition, the bench height of existing benches is mostly fixed, which cannot accommodate the needs of operators of different heights. Prolonged operation can easily cause fatigue, affecting testing accuracy and operator comfort. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] This utility model provides a technical solution: such as Figures 1-6As shown in this embodiment, a comprehensive power testing workbench includes a base 1 and a workbench 2. A fixed frame 6 is fixedly installed on the workbench 2. Multiple sets of equidistantly distributed positioning frames 8 are provided above the fixed frame 6. Two sets of symmetrically distributed guide rails 7 are slidably installed on the fixed frame 6. The two outer sets of positioning frames 8 are fixedly connected to the corresponding two sets of guide rails 7, and the multiple inner sets of positioning frames 8 are slidably connected to the fixed frame 6 and the guide rails 7, respectively. An installation rod 12 is fixedly installed on the fixed frame 6. Two sets of symmetrically distributed first push rods 13 are slidably installed inside the installation rod 12. A second push rod 14 is slidably installed inside each of the two sets of first push rods 13. The outer ends of the two sets of second push rods 14 are fixedly connected to the two sets of guide rails 7, respectively. A positioning seat 19 is fixedly installed on the positioning frame 8. A rotatable mounting seat 19 is installed inside the positioning seat 19. The system is equipped with a take-up rod 20, on which two sets of symmetrically distributed coil springs 21 are sleeved. The inner and outer ends of the coil springs 21 are fixedly connected to the take-up rod 20 and the positioning seat 19, respectively. The positioning seat 19 has a strap 22 that winds around the take-up rod 20. A locking block 23 is fixedly installed on the section of the strap 22 away from the take-up rod 20, and the locking block 23 is movably engaged with the positioning seat 19. Two sets of locking brackets 24 are slidably installed in the positioning seat 19. The two sets of locking brackets 24 and the strap 22 are distributed on both sides of the positioning seat 19, and both sets of locking brackets 24 can be movably engaged with the locking block 23. A rack 25 is fixedly installed on each set of locking brackets 24, and a gear 26 is provided between the two sets of racks 25. The gear 26 meshes with the two sets of racks 25, and the gear 26 is connected to the positioning seat through a mounting shaft 27. 19. A rotating connection is established. Two sets of clamps 24 are centrally symmetrically distributed about the mounting shaft 27. A torsion spring 28 is sleeved on the mounting shaft 27. The two ends of the torsion spring 28 are fixedly connected to the gear 26 and the positioning seat 19, respectively. A slide rod 29 corresponding to the clamping is fixedly installed inside the positioning seat 19. The clamps 24 and the slide rod 29 are slidably sleeved. Two sets of symmetrically distributed springs 30 are sleeved on the slide rod 29. The two ends of the two sets of springs 30 are fixedly connected to the clamps 24 and the positioning seat 19, respectively. Two sets of intersecting first connecting frames 9 and two sets of intersecting second connecting frames 11 are provided between two adjacent sets of positioning frames 8. A movable block 10 is rotatably installed at the front end of each of the two sets of first connecting frames 9. The movable block 10 is slidably connected to the corresponding positioning frame 8. The rear ends of the two sets of first connecting frames 9 are connected by... The two sets of second connecting frames 11 are rotatably connected via rotating shafts at their front ends and at their rear ends to the corresponding positioning frames 8 via rotating shafts. A bidirectional screw 15 is rotatably installed inside the mounting rod 12. Both ends of the bidirectional screw 15 pass through two sets of first push rods 13 and are threadedly connected to them. A threaded tube 17 is rotatably installed inside each of the two sets of first push rods 13. The end of the threaded tube 17 furthest from the first push rod 13 passes through a second push rod 14 and is threadedly connected to it. Two sets of symmetrically distributed keyways 16 are provided on the bidirectional screw 15. Two sets of symmetrically distributed key blocks 18 are provided inside the threaded tube 17. The key blocks 18 and keyways 16 are correspondingly arranged. The threaded tube 17 is slidably sleeved with the bidirectional screw 15 through the key blocks 18 and keyways 16.The linkage adjustment mechanism enables flexible management and fixation of the wire harness. When the spacing of the positioning frames 8 needs to be adjusted, rotating the bidirectional screw 15 drives the two sets of screw tubes 17 to rotate synchronously. Through the transmission of the keyway 16 and the key block 18, the first push rod 13 slides along the mounting rod 12. At the same time, the second push rod 14 extends or retracts under the thread drive of the screw tube 17, pushing the guide rail 7 to move on the fixing frame 6. The displacement of the guide rail 7 is transmitted to each positioning frame 8 through the cross-distributed first connecting frame 9 and second connecting frame 11, so that they are equidistantly extended or retracted. When the wire harness is fixed, the binding strap is pulled out. After bypassing the cable, the locking block 23 is pressed into the positioning seat 19. Before the locking block 23 is engaged with the positioning seat 19, the mounting shaft 27 is rotated, and the two sets of locking brackets 24 move outward synchronously through the transmission of the rack 25 and gear 26. After the locking block 23 is engaged with the positioning seat 19, the mounting shaft 27 is released. Under the action of the spring 30 and the torsion spring 28, the two sets of locking brackets 24 slide inward synchronously to engage the locking block 23, forming a two-way lock. When released, rotating the mounting shaft 27 again will cause the locking brackets 24 to slide in the opposite direction to release the locking block 23. The coil spring 21 automatically retracts the strap 22 to keep the table surface clean.
[0024] like Figure 1 and Figure 2 As shown, two sets of cross-distributed supports 3 are provided between the base 1 and the worktable 2. Sliders 4 are rotatably mounted at both ends of each set of supports 3. The sliders 4 are slidably connected to the corresponding base 1 or worktable 2. A bidirectional lead screw 5 is rotatably installed inside both the base 1 and the worktable 2. The two ends of the bidirectional lead screw 5 pass through the corresponding two sets of slides 4 and are threadedly connected to them. The height adjustment of the worktable 2 is achieved through a lifting mechanism driven by the bidirectional lead screw 5. When the motor inside the base 1 or worktable 2 drives the bidirectional lead screw 5 to rotate, the two sets of slides 4 move in opposite directions along the screw threads, causing the cross supports 3 to unfold or fold, thereby smoothly raising or lowering the worktable 2. The rotatable connection between the slides 4 and the supports 3 ensures a smooth and unobstructed lifting process, while the self-locking characteristic of the bidirectional lead screw 5 can fix the table height at any position. This structure maintains synchronization on both sides during adjustment, preventing table tilting. It adapts to the height requirements of different operators while ensuring the stability of heavy equipment placement, balancing ergonomics and testing accuracy.
[0025] This utility model provides a comprehensive power testing workbench. Its specific working principle is as follows: Flexible management and fixing of the wire harness are achieved through a linkage adjustment mechanism. When the spacing of the positioning frames 8 needs adjustment, rotating the bidirectional screw 15 drives the two sets of screw tubes 17 to rotate synchronously. Through the transmission of the keyway 16 and key block 18, the first push rod 13 slides along the mounting rod 12. Simultaneously, the second push rod 14 extends or retracts under the threaded drive of the screw tube 17, pushing the guide rail 7 to move on the fixed frame 6. The displacement of the guide rail 7 is transmitted to each positioning frame 8 through the cross-distributed first connecting frame 9 and second connecting frame 11, causing them to expand or retract at equal intervals. When fixing the wire harness, pulling out the binding strap 22 and wrapping it around the cable, presses the locking block 23 into the positioning seat 19. Before the locking block 23 is inserted into the positioning seat 19, rotating the mounting shaft 27, through the rack 25 and gear 26, causes the two sets of locking frames 2... 4. Moving outward synchronously, after the locking block 23 engages with the positioning seat 19, the mounting shaft 27 is released. Under the action of the spring 30 and the torsion spring 28, the two sets of locking brackets 24 slide inward synchronously to engage the locking block 23, forming a two-way lock. When released, rotating the mounting shaft 27 again will cause the locking brackets 24 to slide in the opposite direction to release the locking block 23. The coil spring 21 automatically retracts the strap 22 to keep the table surface clean. The height adjustment of the worktable 2 adopts a lifting mechanism driven by a two-way screw 5 to achieve stable lifting and lowering. When the motor in the base 1 or the worktable 2 drives the two-way screw 5 to rotate, the two sets of sliders 4 move in opposite directions along the screw thread, driving the cross bracket 3 to unfold or fold, thereby smoothly lifting or lowering the worktable 2. The rotational connection between the slider 4 and the bracket 3 ensures that the lifting process is smooth and without jamming, while the self-locking characteristic of the two-way screw 5 can fix the table height at any position. This structure maintains synchronization on both sides during the adjustment process, avoiding table tilting. It not only adapts to the height requirements of different operators, but also ensures the stability when placing heavy equipment, taking into account both human-machine efficiency and testing accuracy.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
