Technical Field
[0001] This utility model relates to the technical field of electrolytic aluminum production equipment, and in particular to an insulating clamp for a 600KA busbar lifting frame. Background Technology
[0002] In current electrolytic aluminum production equipment, the insulating pads used for the bolts that connect and fix the clamp legs of the 600KA busbar lifting frame to the frame body are made of SMC material. During long-term use, these pads are prone to crushing and aging, leading to loosening of the connection and insulation failure, which in turn causes sparking. This seriously affects the safety of the busbar lifting operation and the stability of the equipment operation. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a 600KA busbar lifting frame insulation clamp with reasonable structure, reliable insulation performance and buffer function.
[0004] To achieve the above objectives, the following technical solution is adopted:
[0005] An insulating clamp for a 600KA busbar lifting frame includes a frame body and an anode clamp connected to the frame body. The anode clamp includes an upper clamp frame and a lower clamp frame. The inner side of the upper clamp frame is fixedly connected to the upper and lower side plates of the frame body via U-shaped lugs. One end of the inner side of the lower clamp frame is hinged to the lower end of the U-shaped lugs. The clamp is characterized by further comprising:
[0006] U-shaped guardrail, including an upper U-shaped guardrail and a lower U-shaped guardrail that are respectively fixed to the upper side plate and the lower side plate of the frame body;
[0007] A composite pad is provided between the upper U-shaped guard plate and the upper side plate, and between the lower U-shaped guard plate and the lower side plate;
[0008] The fixing components include fixing bolts and fixing nuts. The fixing bolts pass through the upper and lower side plates of the frame body, the U-shaped guard plate, the composite pad layer and the U-shaped ear plate and are then fastened by the fixing nuts.
[0009] The upper U-shaped guard plate, lower U-shaped guard plate, composite pad, U-shaped ear plate, upper side plate, and lower side plate are all provided with through holes corresponding to the positions of the fixing bolts.
[0010] Furthermore, an insulating bushing is provided on the outside of the fixing bolt, and insulating washers are provided between the fixing nut and the U-shaped ear plate, and between the head of the fixing bolt and the upper and lower side plates.
[0011] Furthermore, the composite pad layer includes an elastic pad and an insulating pad, the insulating pad being disposed on the surfaces of the upper and lower side plates, and the elastic pad being disposed between the insulating pad and the inner wall of the U-shaped protective plate.
[0012] Furthermore, the insulating pad is made of polyimide, PEEK composite, or epoxy fiberglass.
[0013] Furthermore, the elastic pad is made of silicone rubber.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. By setting a U-shaped protective plate between the frame body and the U-shaped ear plate of the anode clamp, the composite pad can be effectively protected, avoiding the influence of the external environment on the composite pad, thereby improving its service life, and preventing the composite pad from being damaged and falling off due to long-term use or compression, thus reducing the insulation performance between the frame body and the anode clamp.
[0016] 2. The composite padding layer consists of an insulating pad and an elastic pad. The elastic pad is placed between the U-shaped guard plate and the insulating pad, which can effectively buffer the impact caused by frame vibration or installation stress, reduce the risk of the composite padding layer being crushed and damaged, and extend the service life of the composite padding layer and the overall structure.
[0017] 3. By setting insulating pads, insulating bushings and insulating washers, a reliable insulation structure can be achieved, avoiding arcing during use of the busbar lifting frame, thereby improving the safety of busbar lifting operations. Attached Figure Description

[0023] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the view direction or positional relationship, and are only for the convenience of describing the utility model, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model.
[0024] like Figures 1-2 The 600KA busbar lifting frame insulation clamp shown includes a frame body 1 and an anode clamp 2. The outer side of the frame body 1 has an upper side plate 101 and a lower side plate 102 distributed vertically. The upper end of the anode clamp 2 is provided with an upper clamp frame 201 and a lower clamp frame 202. One end of the inner side of the upper clamp frame 201 is fixedly connected to the upper side plate 101 and the lower side plate 102 of the frame body 1 through a U-shaped ear plate 3. The lower clamp frame 202... 2. One end of the inner side is hinged to the lower inner side of the fixture frame 201. An upper U-shaped guard plate 4 and a lower U-shaped guard plate 5 are respectively provided on the upper side plate 101 and the lower side plate 102. A composite pad is provided between the upper U-shaped guard plate 4 and the upper side plate 101, and between the lower U-shaped guard plate 5 and the lower side plate 102. The upper U-shaped guard plate 4 and the upper side plate 101, and the lower U-shaped guard plate 5 and the lower side plate 102 are detachably connected by a fixing component.
[0025] By setting an upper U-shaped guard plate 4 below the upper side plate 101 and a lower U-shaped guard plate 5 above the lower side plate 102, the composite pad can be protected, preventing it from falling off due to damage caused by prolonged use or compression, which would affect the insulation between the frame body 1 and the anode clamp 2, and prevent arcing of the busbar lifting frame during use.
[0026] The upper U-shaped guard plate 4 and the upper side plate 101, and the lower U-shaped guard plate 5 and the lower side plate 102 have the same structure and connection relationship. Therefore, in this embodiment, the upper U-shaped guard plate 4 and the upper side plate 101 are used as examples for detailed description.
[0027] Specifically, the lower end of the upper side plate 101 is located inside the U-shaped groove of the upper U-shaped guard plate 4. The composite pad is disposed between the surface of the upper side plate 101 and the inner wall of the upper U-shaped guard plate 4 and is distributed in a U-shape. The composite pad consists of an insulating pad 6 and an elastic pad 7. The insulating pad 6 is distributed along the surface of the upper side plate 101. In this embodiment, the insulating pad 6 can be any of a polyimide pad, a PEEK composite board, or an epoxy fiberglass board to ensure good electrical insulation performance. The elastic pad 7 is located between the insulating pad 6 and the inner wall of the upper U-shaped guard plate 4. The elastic pad 7 is made of silicone rubber to improve the pressure resistance and buffering performance of the connection structure. Moreover, the elastic pad 7 can also increase the friction between it and the insulating pad 6 to a certain extent, reducing the risk of it falling off or slipping out.
[0028] The fixing assembly includes a fixing bolt 9 and a fixing nut 10. An insulating bushing 8 is fitted onto the outer surface of the fixing bolt 9. Through holes for the insulating bushing 8 are provided on the U-shaped ear plate 3, the upper U-shaped guard plate 4, the insulating pad 6, the elastic pad 7, and the upper side plate 101. The threaded section of the fixing bolt 9... Figure 2 The components are distributed from right to left in the view direction and extend to the left side of the U-shaped ear plate 3 for a certain length before being fastened by the fixing nut 10. In addition, an insulating washer 11 is provided between the fixing nut 10 and the U-shaped ear plate 3, and between the head of the fixing bolt 9 and the upper U-shaped guard plate 4. By providing the insulating bushing 8 and the insulating washer 11, the insulation between the frame body 1 and the anode clamp 2 can be effectively improved.
[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
