Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinet arrester installation and maintenance, and in particular relates to a loading and unloading tool for switch cabinet arrester. Background Art

[0002] In the prior art, the plug-in arrester for switch cabinet is connected to the switch cabinet by direct insertion of the inner cone bushing. During the initial installation, the arrester mounting head and the epoxy mounting surface inside the inner cone bushing are cleaned and evenly coated with silicone grease, and then the arrester mounting head is inserted into the inner cone bushing for docking. After being inserted into place, the arrester and the inner cone bushing are fastened by screws.

[0003] However, when the arrester needs to be replaced or tested later, the silicone grease that acts as a lubricant on the surface of the arrester and the inner cone casing during operation causes the interior to be in a vacuum state. After the screws are loosened, the operator often needs to expend great effort to pull out the arrester. Due to the small space of the switch cabinet and the installation of arresters between the three phases, the construction space for the construction workers is limited. In the process of disassembling the arrester, there is a situation where it is shaken left and right before being pulled out. This type of operation is likely to damage the equipment in the switch cabinet and the arrester body, and unfavorable factors such as low operating efficiency have remained high. Summary of the invention

[0016] Figure 1 The figure is a schematic diagram of the three-dimensional structure of a loading and unloading tool for a switch cabinet lightning arrester according to an embodiment of the present invention.

[0017] Reference Figure 1 According to an embodiment of the present invention, a loading and unloading tool for a switch cabinet lightning arrester comprises: a stabilizing frame 1, a height adjustment component 2, a handle 3 and a clamping component 4. The stabilizing frame 1 comprises: a first part 11 and a second part 12, one side of the first part 11 and one side of the second part 12 are respectively sleeved on both ends of the height adjustment component 2, and the other side of the first part 11 and the other side of the second part 12 are both fixedly connected to the surface of the switch cabinet. The height adjustment component 2 is in the shape of a long axis as a whole, and the first part 11 and the second part 12 are symmetrical about the center line of the height adjustment component 2. The height adjustment component 2 is movably arranged between the first part 11 and the second part 12, and one end of the handle 3 passes through the height adjustment component 2 and is fixedly connected to the clamping component 4. The clamping component 4 is fixedly arranged on the outer peripheral surface of the lightning arrester. When the handle 3 rotates, the clamping component 4 drives the lightning arrester to move relative to the switch cabinet, thereby completing the loading and unloading operation of the lightning arrester.

[0018] Furthermore, the height adjustment component 2 includes: a positioning shaft 21, a screw rod 22, a fixed screw rod 23, a rotating shaft 24 and a height adjustment nut 25. One end of the positioning shaft 21 is fixedly connected to one end of the screw rod 22 by a thread, and the other end of the positioning shaft 21 is fixedly connected to the fixed screw rod 23. Among them, the outer circumference of the end of the positioning shaft 21 is fixedly connected to the first part 11 by a thread, and the end face of the end of the positioning shaft 21 is fixedly connected to the fixed screw rod 23. The surface of the positioning shaft 21 is recessed to form a limit groove 211 that passes through the axis of the positioning shaft 21. The other end of the screw rod 22 is rotatably connected to the rotating shaft 24, and the height adjustment nut 25 is rotatably arranged on the outer circumference of the screw rod 22. One end of the rotating shaft 24 is rotatably connected to the screw rod 22 by a thread, and the outer circumference of the other end of the rotating shaft 24 is fixedly connected to the second part 12. When encountering switch cabinets of different sizes, the screw rod 22 can be extended or shortened by rotating the height adjustment nut 25, thereby changing the distance between the first part 11 and the second part 12.

[0019] Specifically, the clamping assembly 4 includes: a clamping seat 41, a clamping hoop 42 and a reinforcing shaft 43. The clamping seat 41 is in the shape of a square block as a whole, and a swing arm 411 is fixedly provided on the surfaces of the opposite sides of the clamping seat 41, and a reinforcing shaft 43 is fixedly provided on the end surface of the clamping seat 41 close to one end of the positioning shaft 21. The reinforcing shaft 43 is coaxial with the handle 3, and the clamping seat 41 is fixedly connected to the handle 3 through the reinforcing shaft 43. The clamping hoop 42 is in the shape of a ring as a whole, and a positioning cavity whose size can be adjusted by a connecting member 5 is formed therein. Among them, the two ports on the clamping hoop 42 for adjusting the size of the positioning cavity are respectively connected to the end face of one of the swing arms 411 through the connecting member 5. In this embodiment, the connecting member 5 includes but is not limited to screws, bolts and other threaded fasteners. After the arrester is installed, the lower end of the arrester is inserted into the positioning cavity, and the clamping hoop 42 is fixed to the outer peripheral surface of the arrester by tightening the screws. When the arrester is being installed or removed, the handle 3 is rotated to drive the clamping seat 41 to move, thereby driving the clamp 42 and the arrester to move, thereby releasing the connection between the arrester and the cone sleeve.

[0020] Since the cone sleeve conventionally used to fix the arrester is usually provided with corresponding silicone grease in order to ensure that the plug-in arrester will not fall off during use. After the arrester is installed, the silicone grease will shrink to empty the air in the cone sleeve, thereby forming a vacuum adsorption effect. In order to further improve the effect of the handle 3 to disassemble the arrester. In this embodiment, a plurality of support legs 6 are fixedly and detachably provided on one side of the second part 12 away from the rotating shaft 24, and each support leg 6 is arranged in a circular array with the axis of the rotating shaft 24 as the center of the circle to enhance the connection between the rotating shaft 24 and the ground, thereby ensuring that the rotating shaft 24 always maintains a certain stability during the rotation of the handle 3.

[0021] Preferably, in order to further improve the effect of the handle 3 disassembling the arrester. In this embodiment, the handle 3 is divided into a first section and a second section that are fixedly connected with each other by the rotating shaft 24. Among them, the first section is fixedly connected to the reinforcing shaft 43 after passing through the limiting groove 211. In order for the operator to disassemble more labor-saving, the length of the first section is less than the length of the second section. During the disassembly process of the arrester, the rotating shaft 24 is the fulcrum, and the operator rotates the second section upward, so that the clamp 42 applies a vertical downward force to the arrester. Under the amplification effect of the lever, the arrester can be easily removed.

[0022] In summary, the present invention forms a lever through a support rod and a handle. After the handle is turned, the lever amplifies the pressure of the operator so that the lightning arrester is released from the cone sleeve, thereby achieving the effect of efficiently disassembling the lightning arrester.
