[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] Example 1

[0025] Reference Figure 1 to Figure 5, which is the first embodiment of the present invention, provides a placement component 100, including a support frame 101, and a placement frame 103 arranged on the support frame 101, the placement frame 103 is provided with a bearing plate 104 for placing a switch trolley or an insulation measuring trolley, and the bearing plate 104 is provided with a sliding groove 106 for the roller on the switch trolley or the insulation measuring trolley to move; when the trolley measures the insulation of the switch load, the sliding groove 106 on the bearing plate 104 will be aligned with the guide rail of the switch cabinet first, so as to facilitate the movement of the roller on the insulation measuring trolley or the switch trolley, and then proceed to the next stage of operation.

[0026] The connecting assembly 300 includes a connecting rod 301 disposed on the carrying plate 104 .

[0027] The end of the connecting rod 301 close to the support frame 101 is provided with a rotating rod 302, and the other end passes through the carrier plate 104 and is installed with a connecting cross bar 305. The end of the carrier plate 104 away from the support frame 101 and is surrounded by an adsorption magnetic ring 304. Because the card slot below the switch cabinet guide rail is in a straight line shape, under normal conditions, the connecting cross bar 305 is in a parallel state, so that when the sliding groove 106 is connected to the switch cabinet guide rail, the connecting cross bar 305 can directly slide into the straight line card slot, and then the connecting rod 301 is driven by the rotating rod 302 to rotate ninety degrees, so that the connecting cross bar 305 installed on the connecting rod 301 is in a vertical state, which conflicts with the straight line card slot. However, some newcomers are prone to get stuck when the connecting cross bar 305 is in the straight line card slot. When the switch trolley or the insulation measurement trolley is closed, the sliding groove 106 is not completely connected to the switch cabinet guide rail, and the trolley is prone to slipping. In this embodiment, through the setting of the adsorption magnetic ring 304, one end of the bearing plate 104 is closed under the magnetic force of the adsorption magnetic ring 304 when it is close to the switch cabinet guide rail, even if it is not completely in contact with the guide rail. In this way, the sliding groove 106 will not be loosely connected to the switch cabinet guide rail, thereby reducing the risk of the trolley slipping and improving the protection of the staff and equipment.

[0028] A fastening thread 303 is provided on the surface of the connecting rod 301 and near the connecting rod 301, which is threadedly connected to the bearing plate 104. The threaded connection has self-locking properties. In this embodiment, the fastening thread 303 is provided to increase the connection stability between the sliding groove 106 and the switch cabinet guide rail. In addition, when the connecting rod 301 rotates, the connecting cross bar 305 moves backward under the action of the fastening thread 303, squeezing the straight slot, further improving the stability.

[0029] When in use, the connection between the sliding groove 106 and the switch cabinet rail is achieved through the setting of the connecting component 300, and the setting of the adsorption magnetic ring 304 is utilized so that one end of the bearing plate 104 will automatically fit the switch cabinet rail, thereby avoiding the situation where the sliding groove 106 and the switch cabinet rail are not tightly connected, reducing the risk of the trolley slipping, and improving the protection of the staff and equipment. In addition, the setting of the fastening thread 303 increases the connection stability between the sliding groove 106 and the switch cabinet rail, and when the connecting rod 301 rotates, under the action of the fastening thread 303, the connecting cross bar 305 will move backward, squeezing the straight card slot, further improving the stability.

[0030] Example 2

[0031] Reference Figure 1 to Figure 5 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a locking member 306 for fixing the switch trolley or the insulation measuring trolley is provided in the sliding groove 106, and the locking member 306 includes a receiving groove 306a provided on the bearing plate 104 and connected to the sliding groove 106, a locking rod 306b is rotatably installed in the receiving groove 306a, and one end of the locking rod 306b slides obliquely into the sliding groove 106, and a locking torsion spring 306c connected to the receiving groove 306a is provided at the rotating end of the locking rod 306b, and a knob 306d coaxially fixed to the locking rod 306b is provided on the outside of the bearing plate 104. Figure 3 As shown, when the roller on the switch trolley or the insulation measuring trolley enters the sliding groove 106, the roller will first contact the engaging rod 306a and push the engaging rod 306a to move upward. When the roller is separated from the engaging rod 306b, the engaging rod 306b will be reset under the action of the engaging torsion spring 306c. At this time, if the switch trolley or the insulation measuring trolley is ready to be separated from the device under the action of external force, the roller on it will squeeze the engaging rod 306b to resist the sliding groove 106, so that the engaging rod 306b cannot be opened. In this way, the switch trolley or the insulation measuring trolley can only stay on the carrying plate 104, further reducing the risk of the switch trolley or the insulation measuring trolley being separated. When the switch trolley or the insulation measuring trolley is pushed out of the device, the roller on the switch trolley or the insulation measuring trolley can be pushed away from the engaging rod 306b first. At this time, the engaging rod 306b is controlled to be stored in the accommodating groove 306a by the knob 306d, and the switch trolley or the insulation measuring trolley can be taken out.

[0032] The extended end of the locking rod 306b is parallel to the bottom of the sliding slot 106. The extended end of the locking rod 306b is parallel to the bottom of the sliding slot 106, which increases the contact area between the locking rod 306b and the sliding slot 106, and further increases the stability of the connection between the switch trolley or the insulation measurement trolley and the device.

[0033] When in use, the locking rod 306b is used to fix the roller on the switch trolley or the insulation measuring trolley, so that the switch trolley or the insulation measuring trolley is placed on the supporting plate 104, reducing the risk of the switch trolley or the insulation measuring trolley being detached, and the contact area between the locking rod 306b and the sliding groove 106 is increased by utilizing the special setting of the extended end of the locking rod 306b, thereby increasing the stability of the connection between the switch trolley or the insulation measuring trolley and the device.

[0034] The remaining structures are the same as those of Example 1.

[0035] Example 3

[0036] Reference Figure 1 to Figure 5 , is the third embodiment of the present invention, which is different from the second embodiment in that: the placement rack 103 is slidably connected with the support rack 101, and the support rack 101 is provided with an adjustment component 200 for adjusting the height of the placement rack 103 from the ground, and the adjustment component 200 includes an adjustment cylinder 201 arranged on the support rack 101, and an adjustment sprocket 202 is arranged at the output end of the adjustment cylinder 201, and an adjustment chain 203 is meshed on the surface of the adjustment sprocket 202, and the two ends of the adjustment chain 203 are respectively fixed to the adjustment cylinder 201 and the placement rack 103, and a pedal 204 is arranged on the adjustment cylinder 201. The heights of different switch cabinets are different, and when the insulation measuring trolley is transported, the height of the insulation measuring trolley will be lowered by lowering the center of gravity, so that the stability of the insulation measuring trolley transportation can be improved. In this embodiment, the function of adjusting the height of the bearing plate 104 can be realized by setting the adjustment component 200. When used, the movement of the adjustment cylinder 201 can be controlled by stepping on the pedal 204, and then the height of the placement rack 103 can be controlled by using the adjustment chain 203.

[0037] A friction-reducing roller 105 is provided between the placement rack 103 and the support rack 101. When the placement rack 103 moves, it will rub against the support rack 101. The setting of the friction-reducing roller 105 converts the sliding friction between it and the support rack 101 into rolling friction, thereby reducing the friction loss between the placement rack 103 and the support rack 101 and extending its service life.

[0038] A moving roller 102 is provided at the bottom of the support frame 101, and a locking structure is provided on the moving roller 102. The setting of the moving roller 102 facilitates the transportation of the operating trolley, and the locking device provided thereon can fix the moving roller 102 when the insulation trolley and the switch trolley enter and exit the switch cabinet to prevent the moving roller 102 from moving and causing the trolley to detach, thereby increasing the protection of the equipment.

[0039] When in use, by adjusting the setting of the component 200, the height of the supporting plate 104 can be adjusted as needed, thereby expanding the application range of the device, and by utilizing the setting of the anti-friction roller 105, the sliding friction between it and the support frame 101 is converted into rolling friction, thereby reducing the friction loss between the placement frame 103 and the support frame 101.

[0040] The remaining structure is the same as that of Example 2.
