[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Please see Figures 1-7 A comprehensive electrical equipment performance testing device includes a comprehensive testing box 1 and a traveling base 2. Guide wheels are installed at the bottom of the traveling base 2, and a bracket 3 is fixedly connected to the top of the traveling base 2. A suspension frame 4 is rotatably connected to the top of the bracket 3. One end of the suspension frame 4 is rotatably connected to the comprehensive testing box 1, and the rotation axes of both are horizontal, allowing the comprehensive testing box 1 to be in a suspended state. When the suspension frame 4 swings down to its extreme position, the bottom of the comprehensive testing box 1 will contact the upper surface of the traveling base 2. Furthermore, the up-and-down swinging design of the suspension frame 4 allows the height of the comprehensive testing box 1 to be adjusted, facilitating efficient docking tests on electrical equipment of different heights on site.

[0038] In a specific implementation, it is preferred that the suspension frame 4 includes a portal rod 41 and a connecting rod 42. The bracket 3 is rotatably connected to both sides of the integrated test box 1 through the portal rod 41 and the connecting rod 42. The bracket 3, the portal rod 41, the connecting rod 42 and the integrated test box 1 form a parallel hinge four-bar mechanism. This arrangement ensures that the integrated test box 1 is always in a vertical position when it is raised or lowered, which is convenient for the operator to operate the control panel of the integrated test box 1.

[0039] The suspension frame 4 is sway-connected to the lateral protection trigger frame 5 located on both sides of the integrated test box 1. The top of the integrated test box 1 is slidably connected to the top protection trigger frame 6. The lateral protection trigger frame 5 and the top protection trigger frame 6 are structures that directly bear external impacts, thus enabling the integrated test box 1 to be protected from impacts from three directions. The front side of the integrated test box 1 is the operating side, its back side is opposite to the bracket 3, and its bottom side is opposite to the walking base 2. Thus, the five sides of the integrated test box 1 are protected from direct impacts.

[0040] Furthermore, the bracket 3 is equipped with a clutch control group 7 and a winding buffer 8. The clutch control group 7 has the function of clutch control and also has the function of locking the suspension frame 4. Specifically, when the lateral protection trigger frames 5 on both sides of the suspension frame 4 do not have trigger displacement at the same time, under the transmission of the clutch control group 7, the suspension frame 4 swings down while the winding buffer 8 decelerates and buffers the swing of the suspension frame 4. A linkage triggering structure 9 is provided between the top protection trigger frame 6 and the lateral protection trigger frames 5. When the top protection trigger frame 6 has trigger displacement, under the action of the linkage triggering structure 9, the lateral protection trigger frame 5 on one side of the suspension frame 4 will have trigger displacement. The trigger displacement mentioned above refers to the displacement generated when impacted. This displacement will disengage the locking of the suspension frame 4 through the clutch control group 7. At this time, the suspension frame 4 will swing down to reduce the height of the integrated test box 1 and move it away from the impact zone. At the same time, when the suspension frame 4 swings down, the winding buffer 8 will slow down its descent to avoid the integrated test box 1 being subjected to inertial impact.

[0041] Specifically, a positioning cylinder 31 is fixedly connected to the top of the bracket 3, and the intermediate shaft 411 on the portal rod 41 is housed in the positioning cylinder 31. The intermediate shaft 411 and the positioning cylinder 31 are coaxial. When the portal rod 41 swings up and down, it will drive the intermediate shaft 411 to rotate in the positioning cylinder 31. The clutch control group 7 includes an intermediate bevel gear 71 and a transmission bevel gear 72. There are two transmission bevel gears 72, which are sleeved on the intermediate shaft 411. The intermediate bevel gear 71 is rotatably connected to the inner circumferential wall of the positioning cylinder 31 and is located between the two transmission bevel gears 72. The two transmission bevel gears 72 and the intermediate shaft 411 are axially elastically slidingly engaged with the intermediate bevel gear 71. The thrust generated by the elasticity here causes the two transmission bevel gears 72 to move to their extreme positions in opposite directions. When the two transmission bevel gears 72 are simultaneously engaged with the intermediate bevel gear 71, the intermediate shaft 411 cannot rotate relative to the positioning cylinder 31, thereby locking the gate rod 41. When one or two transmission bevel gears 72 are separated from the intermediate bevel gear 71, the locking of the intermediate shaft 411 is released. At this time, the gate rod 41 can swing down by its own weight to realize the downward movement protection function of the comprehensive test box 1.

[0042] Each of the two transmission bevel gears 72 has a fixed connecting shaft 721 on its opposite side, which is movably connected to the adjacent lateral protection trigger frame 5. Specifically, when the lateral protection trigger frame 5 is impacted and displaced, it will drive the corresponding connecting shaft 721 to move outward, thereby causing the corresponding transmission bevel gear 72 and the intermediate bevel gear 71 to separate, thus achieving downward protection of the integrated test box 1 in the event of a lateral impact. It should be noted that after a single transmission bevel gear 72 and intermediate bevel gear 71 separate, when the portal rod 41 swings down, the other transmission bevel gear 72 will drive the intermediate bevel gear 71 to rotate; when both transmission bevel gears 72 and 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 lateral protection trigger frame 5 includes an arm 51 and a side protection pad 52 fixedly installed at one end of the arm 51. The side protection pad 52 is located on one side of the integrated test chamber 1 and is used to withstand impact. The arm 51 is Z-shaped, and both sides of the portal-shaped rod 41 are fixedly connected to support arms 412 that are hinged to the body of the arm 51. In specific implementation, pins can be welded onto the support arms 412, and then waist-shaped holes can be opened on the body of the arm 51 and fitted onto the outside of the pins. The support arms 412 are located close to the bracket 3. When the side protection pad 52 is impacted, it will swing towards the integrated test chamber 1, thereby causing the support arms 412 to swing. When the support arms 412 swing, it will cause the transmission shaft 721 to move outward. A support platform 4111 is welded to the intermediate shaft 411 and is located at both ends and sleeved in the positioning cylinder 31. The support platform 4111 and the positioning cylinder 31 are rotatably connected. The transmission shaft 721 is provided through the support platform 4111 and its free end is hinged to the other end of the adjacent arm 51. In specific implementation, a guide tube sleeved on the outside of the transmission shaft 721 can be fixed on the support platform 4111. A return spring 74 is sleeved on the transmission shaft 721 between the support platform 4111 and the adjacent transmission bevel gear 72. When the transmission shaft 721 moves outward, the adjacent return spring 74 will be compressed. It should be noted that the return spring 74 here also plays the role of buffering impact.

[0044] The integrated test box 1 has a positioning shaft 11 welded on both sides and rotatably connected to the free end of the portal rod 41. The two ends of the positioning shaft 11 are welded with guide sleeves 111. The top protection trigger frame 6 includes a portal plate 61 and a top pad 62 located on the top of the portal plate 61. The two uprights 611 on the portal 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 portal plate 61. The top pad 62 is used for air-proof protection of the integrated test box. The linkage triggering structure 9 includes a truncated cone 91 and a roller 92. One side of one of the uprights 611 is rotatably connected to a roller 92 located outside the upright 611 via a channel beam 6111. The roller 92 is located outside the adjacent upright 611 and the two are in a perpendicular state. When the portal plate 61 moves downward, it will drive the roller 92 to move downward. The outer conical wall of the truncated cone 91 and the outer peripheral wall of the roller 92 abut against each other, and one end of the roller 92 is fixedly connected to one side of the adjacent side protective pad 52. The roller 92 is located on the upper part of the truncated cone 91. The truncated cone 91 and the positioning shaft 11 are coaxial. This arrangement enables the integrated test box 1 to achieve reliable contact between the roller 92 and the truncated cone 91 at any height position. Therefore, when the gantry plate 61 is impacted and moves downward, the roller 92 will move downward, and then the conical surface of the truncated cone 91 will push the adjacent arm 51 to swing towards the integrated test box 1. Then, according to the above principle, the gantry rod 41 will swing downward, realizing the downward protection function of the integrated test box 1. It should be noted that, that is, there is no roller 92 on the other upright 611.

[0045] In use, a buffer spring can be installed between the top of the portal plate 61 and the top of the integrated test box 1. The buffer spring not only serves as a buffer but also serves to reset the portal plate 61.

[0046] In this embodiment, the support 3 is a slotted structure with the opening facing upwards. The clutch control group 7 includes a gear transmission group 73. The winding buffer 8 includes a winding roller 81, a torsion roller 82, and a rope 83. The winding roller 81 and the torsion roller 82 are rotatably connected within the support 3 and are distributed vertically. The winding roller 81 and the torsion roller 82 are connected by the rope 83. Specifically, a torsion spring is provided between the torsion roller 82 and the support 3. The rope 83 is wound around the torsion roller 82. When the rope 83 is pulled, the torsion roller 82 will rotate, and the torsion spring will be compressed. The other end of the rope 83 is fixedly connected to the outer peripheral wall of the winding roller 81. Thus, the winding roller 81 will experience rotational resistance when rotating in both directions. A connecting shaft 711 that is rotatably connected to the positioning cylinder 31 is welded to one side of the intermediate bevel gear 71. 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, thereby realizing the winding function.

[0047] Specifically, the gear transmission assembly 73 includes an external gear ring 731 and a transition bevel gear 732. The external gear ring 731 is sleeved on the outside of the positioning cylinder 31 and the two are rotatably 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, which is rotatably connected to the bracket 3, is fixedly connected to the middle of the winding roller 81. A transmission gear 8111, which meshes with the external gear ring 731, is fixedly sleeved on the support shaft 811. When the intermediate bevel gear 71 rotates, it will drive the external gear ring 731 to rotate under the meshing engagement 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 drive gear 1011 that meshes with the transmission gear 8111. The control motor 101 is designed with braking and releasing functions. This configuration of the transmission mechanism facilitates the control of the up-and-down swing of the gantry rod 41. In other words, when the control motor 101 is started to drive the drive gear 1011 to rotate, one of the side protective pads 52 needs to be pressed first to separate the transmission bevel gear 72 from the middle bevel gear 71, thereby controlling the height of the integrated test box 1.

[0049] Working principle: Before use, a cushioning pad is laid on the upper surface of the walking base 2 to cushion the rapid descent of the comprehensive test box 1. In use, when testing electrical equipment at a certain height on site, the portal arm 41 swings upward to raise the height of the integrated test box 1. When the side protective pad 52 on one of the side protective trigger frames 5 is vibrated or impacted and causes a trigger displacement, the side protective pad 52 will swing towards the integrated test box 1, thereby driving the support arm 412 to swing. When the support arm 412 swings, it will drive the transmission shaft 721 to move outward, the adjacent return spring 74 will be compressed, the corresponding transmission shaft 721 will move outward, thereby driving the corresponding transmission bevel gear 72 and the intermediate bevel gear 71 to separate. At this time, the portal arm 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 drives the winding roller 81 to rotate under the transmission of the gear transmission group 73. At this time, the winding roller 81 wraps around the rope body 83, and the torque roller 82 rotates with resistance to release the rope body 83, realizing the function of slow descent and displacement of the integrated test box 1 to avoid the impact position and avoid secondary impact.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
