Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment testing, and particularly to a comprehensive performance testing device for electrical equipment. Background Art

[0002] The performance testing of electrical equipment mainly includes tests such as withstand voltage, insulation, grounding, voltage, current, leakage, power, start-stop, etc. Currently, on the market, there is an integrated test box for the above-mentioned tests. The integrated test box is of a box structure, and therein are provided circuit modules and control modules related to the tests. On the front side of the box are provided a display, an operation panel, indicator lights, etc. According to the requirements of on-line testing and off-line testing, the integrated test box is usually set as a fixed type and a movable type. Among them, the movable integrated test box is commonly used for regular or daily maintenance on-site.

[0003] Currently, the existing movable integrated test box for on-site testing still has deficiencies in the process of use: 1. The integrated test box has precision components inside, and does not have or has poor anti-impact performance. During on-line testing, the problem of frequent collisions easily occurs, and the existing integrated test box does not have an automatic displacement protection function against impacts, thus easily causing damage to the test box; 2. Currently, on the market, there are shock-absorbing or anti-seismic structures provided on the integrated test box, but such shock-absorbing and buffering structures are usually directly attached to the outside of the integrated test box, resulting in poor buffering effect of the shock-absorbing or anti-seismic structure when an impact occurs, and the integrated test box will still be subjected to a certain degree of impact.

[0004] Therefore, the present invention proposes a comprehensive performance testing device for electrical equipment. Summary of the Invention

[0005] The purpose of the present invention is to propose a comprehensive performance testing device for electrical equipment in order to solve the problems mentioned in the background art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An integrated electrical equipment performance testing device includes an integrated testing box and a walking base. A bracket is fixedly connected to the top of the walking base. The top of the bracket is rotatably connected to a suspension bracket. One end of the suspension bracket is rotatably connected to the integrated testing box, and the rotation axis of the two is horizontal. On both sides of the suspension bracket, there are laterally protective trigger brackets located on both sides of the integrated testing box and swing-connected. A top protective trigger bracket is slidably connected up and down on the top of the integrated testing box. A clutch control group and a wire-winding buffer are arranged on the bracket. When the laterally protective trigger brackets on both sides of the suspension bracket do not simultaneously have trigger displacements, under the transmission of the clutch control group, while the suspension bracket swings downward, the wire-winding buffer will decelerate and buffer the downward swing of the suspension bracket. A linkage trigger structure is arranged between the top protective trigger bracket and the laterally protective trigger brackets. When the top protective trigger bracket has a trigger displacement, under the action of the linkage trigger structure, one of the laterally protective trigger brackets on the suspension bracket will have a trigger displacement.

[0008] As a further description of the above technical solution:

[0009] The suspension bracket includes a portal rod and a connecting rod. The bracket is rotatably connected to both sides of the integrated testing box through the portal rod and the connecting rod. The bracket, the portal rod, the connecting rod, and the integrated testing box form a parallel hinge four-bar mechanism.

[0010] As a further description of the above technical solution:

The clutch control group includes an intermediate bevel gear and a driving bevel gear. The number of driving bevel gears is two and they are sleeved on the middle shaft. The intermediate bevel gear is rotatably connected to the inner peripheral wall of the positioning cylinder and is located between the two driving bevel gears. The two driving bevel gears are axially elastically slidably matched with the middle shaft and are meshed with the intermediate bevel gear. A conduction shaft that is movably connected to the adjacent laterally protective trigger bracket is fixedly connected to the back side of each of the two driving bevel gears.

[0012] As a further description of the above technical solution:

[0013] The laterally protective trigger bracket includes an arm rod and a side protective pad fixedly arranged at one end of the arm rod. Support arms that are hinged to the rod body of the arm rod are fixedly connected to both sides of the portal rod. Support platforms that are welded at both ends on the middle shaft and are sleeved in the positioning cylinder are provided. The support platforms are rotatably connected to the positioning cylinder. The conduction shaft penetrates through the support platform and its free end is hinged to the other end of the adjacent arm rod. A return spring is sleeved on the conduction shaft and is located between the support platform and the adjacent driving bevel gear.

[0014] As a further description of the above technical solution:

[0015] Positioning shafts rotatably connected to the free ends of the portal rods are welded to both sides of the comprehensive test box. Guide sleeves are welded to both ends of the positioning shafts. The top protection trigger frame includes a portal plate and a top pad located at the top of the portal plate. Two vertical rods on the portal plate are respectively sleeved in the guide sleeves at both ends of the positioning shafts. The linkage trigger structure includes a frustum and a roller. One side of one of the vertical rods is rotatably connected to a roller located outside the vertical rod through a channel-shaped beam. The outer conical wall of the frustum abuts against the outer peripheral wall of the roller, and one end of the frustum is fixedly connected to one side of the adjacent side protection pad. The frustum and the positioning shaft are coaxial.

[0016] As a further description of the above technical solution:

[0017] The bracket is a channel-shaped structure with an upward opening. The clutch control group includes a gear transmission group. The winding buffer includes a winding roller, a torsion roller, and a rope body. The winding roller and the torsion roller are rotatably connected in the bracket and are distributed vertically. The winding roller and the torsion roller are connected by a rope body. A connecting shaft rotatably connected to the positioning cylinder is welded to one side of the intermediate bevel gear. The winding roller is connected to the connecting shaft through a gear transmission group.

[0018] As a further description of the above technical solution:

[0019] The gear transmission group includes an outer gear ring and a transition bevel gear. The outer gear ring is sleeved outside the positioning cylinder and the two are rotatably connected. A bevel gear ring is welded to one side of the outer gear ring. The transition bevel gear is fixedly sleeved on the connecting shaft and meshes with the bevel gear ring. A support shaft rotatably connected to the bracket is fixedly connected to the middle of the winding roller. A transmission gear meshing with the outer gear ring is fixedly sleeved on the support shaft.

[0020] As a further description of the above technical solution:

[0021] A control motor is fixedly connected to one side of the bracket. The output shaft of the control motor is fixedly connected to a driving gear meshing with the transmission gear.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, a bracket, a suspension bracket, a top protection trigger frame, and a side protection trigger frame are provided. Among them, the comprehensive test box is suspended at the free end of the suspension bracket. The suspension bracket is rotatably connected to the top of the bracket. Side protection trigger frames are provided on both sides of the comprehensive test box, and a top protection trigger frame is provided at the top. Then, a clutch control group and a winding buffer are provided on the bracket. When the left and right sides or the top of the comprehensive test box are impacted, the suspension bracket will swing downward to drive the comprehensive test box to buffer and sink, away from the impact area. This setting has an impact displacement self-protection function, greatly improving the self-protection performance of the comprehensive test box.

[0024] 2. In the present invention, the top protection trigger frame and the side protection trigger frame are both in a state of not being directly connected to the comprehensive test box. When the top protection trigger frame and the side protection trigger frame are impacted, only a small amount of the vibration generated by the impact will be transmitted to the comprehensive test box, and this kind of setting greatly improves the shock absorption and buffering protection effect on the comprehensive test box.

[0025] 3. In the present invention, the clutch control combination provided includes an intermediate bevel gear and two drive bevel gears. When the two drive bevel gears are simultaneously engaged with an intermediate bevel gear, the suspension frame is in a fixed position. Conversely, it can push the suspension frame to swing up and down to adjust the height of the comprehensive test box, facilitating the testing of electrical equipment at different heights on-site, and thus greatly improving the testing efficiency.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] Embodiment 1

[0037] Please refer to Figure 1-7 , an electrical equipment performance comprehensive test device, including a comprehensive test box 1 and a walking base 2. Guide wheels are installed at the bottom of the walking base 2, and a bracket 3 is fixedly connected to the top of the walking base 2. A suspension bracket 4 is rotatably connected to the top of the bracket 3. One end of the suspension bracket 4 is rotatably connected to the comprehensive test box 1, and the rotation axes of the two are horizontal. At this time, the comprehensive test box 1 can be in a suspended state. When the suspension bracket 4 swings down to the limit position, the bottom of the comprehensive test box 1 will contact the upper end surface of the walking base 2, and the up-and-down swing of the suspension bracket 4 makes the height of the comprehensive test box 1 adjustable, which is convenient for efficient docking tests of electrical equipment at different heights on site.

[0038] Specifically, preferably, the suspension bracket 4 includes a portal rod 41 and a link rod 42. The bracket 3 is rotatably connected to both sides of the comprehensive test box 1 through the portal rod 41 and the link rod 42. The bracket 3, the portal rod 41, the link rod 42, and the comprehensive test box 1 form a parallel hinge four-bar mechanism. This setting makes the comprehensive test box 1 always in a vertical state during lifting, which is convenient for operators to operate the operation panel of the comprehensive test box 1.

[0039] Among them, both sides of the suspension bracket 4 are swing-connected with lateral protection trigger brackets 5 located on both sides of the comprehensive test box 1. The top of the comprehensive test box 1 is slidably connected up and down with a top protection trigger bracket 6. The lateral protection trigger bracket 5 and the top protection trigger bracket 6 are structures that directly bear external impacts, so that the comprehensive test box 1 can be protected from impacts in three directions. Among them, the front side of the comprehensive test box 1 is the operation side, its back side is opposite to the bracket 3, and the bottom is opposite to the walking base 2. Thus, five sides of the comprehensive test box 1 will be protected from direct impacts.

[0040] Furthermore, a clutch control group 7 and a wire winding buffer 8 are arranged on the bracket 3. The clutch control group 7 has the function of clutch control and also has the function of locking the suspension bracket 4. Specifically, when the lateral protection trigger brackets 5 on both sides of the suspension bracket 4 do not simultaneously have trigger displacements, under the transmission of the clutch control group 7, while the suspension bracket 4 swings downward, the wire winding buffer 8 will decelerate and buffer the downward swing of the suspension bracket 4. A linkage trigger structure 9 is arranged between the top protection trigger bracket 6 and the lateral protection trigger bracket 5. When the top protection trigger bracket 6 has a trigger displacement, under the action of the linkage trigger structure 9, one of the lateral protection trigger brackets 5 on one side of the suspension bracket 4 will generate a trigger displacement. The above-mentioned trigger displacement refers to the displacement generated when being impacted, and this displacement will release the locking of the suspension bracket 4 through the clutch control group 7. At this time, the suspension bracket 4 will swing downward to lower the height of the comprehensive test box 1 and make it away from the impact area. At the same time, when the suspension bracket 4 swings downward, the wire winding buffer 8 will make it descend slowly to avoid the comprehensive test box 1 from being impacted by inertia.

[0041] Specifically, a positioning cylinder 31 is fixedly connected to the top of the bracket 3. The middle shaft 411 on the portal rod 41 is accommodated in the positioning cylinder 31, and the middle shaft 411 and the positioning cylinder 31 are coaxial. When the portal rod 4 swings up and down, it will drive the middle shaft 411 to rotate in the positioning cylinder 31. The clutch control group 7 includes an intermediate bevel gear 71 and transmission bevel gears 72. The number of the transmission bevel gears 72 is two and they are sleeved on the middle shaft 411. The intermediate bevel gear 71 is rotatably connected to the inner peripheral wall of the positioning cylinder 31 and is located between the two transmission bevel gears 72. The two transmission bevel gears 72 are axially elastically slidably matched with the middle shaft 411 and are meshed with the intermediate bevel gear 71. The thrust generated by the elasticity here makes the two transmission bevel gears 72 move in opposite directions to the limit position. When the two transmission bevel gears 72 are simultaneously meshed with the intermediate bevel gear 71, the middle shaft 411 cannot rotate relative to the positioning cylinder 31, and then the portal rod 41 is locked. When one or both of the transmission bevel gears 72 are separated from the intermediate bevel gear 71, the locking of the middle shaft 411 is released. At this time, the portal rod 41 can swing downward by its own weight to realize the downward protection function of the comprehensive test box 1.

[0042] Among them, conduction shafts 721 fixedly connected to the back sides of the two transmission bevel gears 72 and movably connected to the adjacent side protection trigger frame 5 are provided. Specifically, when the side protection trigger frame 5 is impacted and displaced, it will drive the corresponding conduction shaft 721 to move outwards, thereby driving the corresponding transmission bevel gear 72 to separate from the intermediate bevel gear 71, realizing the downward protection when the side impact of the comprehensive test box 1 occurs. It should be noted that after a single transmission bevel gear 72 separates from the intermediate bevel gear 71, when the portal rod 41 swings downward, the other transmission bevel gear 72 will drive the intermediate bevel gear 71 to rotate; when the two transmission bevel gears 72 and the intermediate bevel gear 71 separate simultaneously, the downward swing of the portal rod 41 will not drive the intermediate bevel gear 71 to rotate.

[0043] Furthermore, the side protection trigger frame 5 includes an arm rod 51 and a side protection pad 52 fixedly arranged at one end of the arm rod 51. The side protection pad 52 is located on one side of the comprehensive test box 1 and is used to bear the impact. The arm rod 51 is Z-shaped. Both sides of the portal rod 41 are fixedly connected with support arms 412 hinged to the rod body of the arm rod 51. Specifically, when implementing, a pin shaft can be welded on the support arm 412, and then a waist-shaped hole sleeved outside the pin shaft is opened on the rod body of the arm rod 51. The support arm 412 is close to the support 3. When the side protection pad 52 is impacted, it will swing towards the comprehensive test box 1, thereby driving the support arm 412 to swing. When the support arm 412 swings, it will drive the conduction shaft 721 to move outwards. Support platforms 4111 welded on the intermediate shaft 411 and located at both ends and sleeved in the positioning cylinder 31 are provided. The support platforms 4111 are rotatably connected to the positioning cylinder 31. The conduction shaft 721 is arranged through the support platform 4111 and its free end is hinged to the other end of the adjacent arm rod 51. Specifically, when implementing, a guide tube sleeved outside the conduction shaft 721 can be fixedly arranged on the support platform 4111. A return spring 74 is sleeved on the conduction shaft 721 between the support platform 4111 and the adjacent transmission bevel gear 72. When the conduction shaft 721 moves outwards, the adjacent return spring 74 will be compressed. It should be noted that the return spring 74 here also plays a role in buffering the impact.

[0044] Among them, positioning shafts 11 rotatably connected to the free ends of the door-shaped rods 41 are welded on both sides of the comprehensive test box 1, and guide sleeves 111 are welded at both ends of the positioning shaft 11. The top protection trigger frame 6 includes a door-shaped plate 61 and a top pad 62 located on the top of the door-shaped plate 61. The two vertical rods 611 on the door-shaped plate 61 are respectively sleeved in the guide sleeves 111 at both ends of the positioning shaft 11, thereby realizing the up and down sliding function of the door-shaped plate 61, wherein the top pad 62 is used for air-proof protection of the comprehensive test box. The linkage trigger structure 9 includes a frustum 91 and a roller 92, wherein one side of one vertical pole 611 is rotatably connected to a roller 92 located on the outside of the vertical pole 611 through a trough beam 6111, and the roller 92 is located on the outside of the adjacent vertical pole 611 and the two are in a vertical state. When the door-type plate 61 moves downward, it will drive the roller 92 to move downward, and the outer conical wall of the frustum 91 and the outer peripheral wall of the roller 92 are abutted against each other and one end thereof is fixedly connected to one side of the adjacent side protection pad 52. The roller 92 is located at the upper part of the frustum 91, and the frustum 91 and the positioning shaft 11 are coaxial. This arrangement enables the comprehensive test box 1 to evenly achieve reliable fit between the roller 92 and the frustum 91 at any height position. Therefore, when the door-shaped plate 61 is hit and moves downward, the roller 92 will move downward, and then use the conical surface of the truncated cone 91 to push the adjacent arm 51 to swing toward the direction of the integrated test box 1, and then trigger the door-shaped rod 41 to swing downward according to the above principle, so as to realize the downward movement protection function of the integrated test box 1. It should be noted that, that is, the roller 92 is not set on the other vertical rod 611.

[0045] When in use, a buffer spring may be arranged between the top of the door-shaped plate 61 and the top of the integrated test box 1 , and the buffer spring not only plays a buffering role, but also plays a role in resetting the door-shaped plate 61 .

[0046] In this embodiment, the bracket 3 is a groove-shaped structure with an opening facing upward, the clutch control group 7 includes a gear transmission group 73, and the winding buffer 8 includes a winding roller 81, a torsion roller 82 and a rope body 83. The winding roller 81 and the torsion roller 82 are rotatably connected in the bracket 3 and are distributed up and down. The winding roller 81 and the torsion roller 82 are connected through the rope body 83. Specifically, a torsion spring is arranged between the torsion roller 82 and the bracket 3, and the rope body 83 is wound on the torsion roller 82. When the rope body 83 is pulled, the torsion roller 82 will rotate, the torsion spring will be compressed, and the other end of the rope body 83 is fixedly connected to the outer peripheral wall of the winding roller 81, so that the winding roller 81 will be subject to rotation resistance when it is rotated forward and reversed. A connecting shaft 711 rotatably connected to the positioning cylinder 31 is welded on one side of the intermediate bevel gear 71, and the winding roller 81 is connected to the connecting shaft 711 through the gear transmission group 73. Specifically, when the intermediate bevel gear 71 rotates, it drives the winding roller 81 to rotate under the transmission of the gear transmission group 73 to realize the winding function.

[0047] Specifically, the gear transmission group 73 includes an external gear ring 731 and a transition bevel gear 732. The external gear ring 731 is sleeved outside the positioning cylinder 31 and the two are rotationally connected. A bevel gear ring 7311 is welded to one side of the external gear ring 731. The transition bevel gear 732 is fixedly sleeved on the connecting shaft 711 and meshes with the bevel gear ring 7311. A support shaft 811 rotatably connected to the bracket 3 is fixedly connected to the middle of the winding roller 81. A transmission gear 8111 meshing with the external gear ring 731 is fixedly sleeved on the support shaft 811. At this time, when the intermediate bevel gear 71 rotates, it will drive the external gear ring 731 to rotate under the meshing cooperation of the transition bevel gear 732 and the bevel gear ring 7311, and then drive the winding roller 81 to rotate through the transmission gear 8111.

[0048] Furthermore, a control motor 101 is fixedly connected to one side of the bracket 3. The output shaft of the control motor 101 is fixedly connected to a driving gear 1011 meshing with the transmission gear 8111. The control motor 101 is selected to have a structure with braking and brake release functions. This kind of setting of the above-mentioned transmission mechanism facilitates controlling the up and down swing of the portal rod 41. That is to say, when starting the control motor 101 to drive the driving gear 1011 to rotate, one of the side protection pads 52 needs to be pressed first to separate one of the transmission bevel gears 72 from the intermediate bevel gear 71, thereby controlling the height of the comprehensive test box 1.

[0049] Working principle: Before use, a buffer rubber pad is laid on the upper end surface of the traveling base 2 for buffering the rapidly descending comprehensive test box 1. During use, when testing electrical equipment at a certain height on site, the portal rod 41 swings upward to raise the height of the comprehensive test box 1. When one of the side protection pads 52 on the side protection trigger frame 5 is triggered to generate a trigger displacement due to vibration or impact, the side protection pad 52 will swing towards the comprehensive test box 1, thereby driving the swing of the support arm 412. When the support arm 412 swings, it will drive the conduction shaft 721 to move outwards. The adjacent return spring 74 will be compressed, and the corresponding conduction shaft 721 will move outwards, thereby driving the corresponding transmission bevel gear 72 to separate from the intermediate bevel gear 71. At this time, the portal rod 41 will swing downward, and the other transmission bevel gear 72 will drive the intermediate bevel gear 71 to rotate. When the intermediate bevel gear 71 rotates, it will drive the winding roller 81 to rotate under the transmission of the gear transmission group 73. At this time, the winding roller 81 winds the rope body 83, and the torsion roller 82 rotates with resistance to release the rope body 83, realizing the function of the slow descent and displacement of the comprehensive test box 1 to avoid the impact position and preventing secondary impact.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
