Description

Technical Field

[0001] This utility model relates to the field of power equipment installation technology, and in particular to a grounding heat exchanger mold fixing fixture. Background Technology

[0002] Conventional substations typically use a grounding method consisting of flat grounding iron and vertical grounding electrodes. If the grounding resistance does not meet the requirements, external grounding wires are extended outside the station or grounding wells are used to reduce resistance. In highly corrosive desert and Gobi areas, a combination of horizontal copper grounding electrodes and vertical copper grounding rods is generally used to reduce resistance. Because copper grounding electrodes have a high melting point and are prone to forming copper oxide (commonly known as verdigris) when directly welded in air, they cannot meet the requirements of grounding electrodes. Therefore, copper grounding electrodes are usually constructed using a special mold with exothermic welding flux. The exothermic welding flux is then ignited using a special welding torch, and two different copper grounding electrodes are fused together at high temperatures. Since the combination methods of grounding electrodes are linear, cross-shaped, T-shaped, etc., the molds are all different. However, there is a problem with these molds: when the exothermic welding flux releases heat, it generates a large amount of heat that can easily damage the mold. The main reason is that the grounding electrode mold is not tightly closed, and the heat release is uneven, which can easily lead to mold damage or explosion. This is risky and costly. Therefore, an exothermic clamp that can cool quickly and has a good clamping effect is needed. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-3As shown, a grounding heat releaser mold fixing fixture is used to clamp a flat steel grounding heat release mold 7. It is characterized by including a support rod 1, on which two sets of clamping plates 2 are symmetrically arranged. The clamping plates 2 are perpendicular to the support rod 1. Several heat-conducting rods 9 and several positioning rods 10 are also arranged on one side of the clamping plates 2 on the support rod 1. The two sets of clamping plates 2 are fixedly clamped to the flat steel grounding heat release mold 7 by bolts. Several through holes are opened on the flat steel grounding heat release mold 7. The heat-conducting rods 9 and positioning rods 10 are detachably connected to the flat steel grounding heat release mold 7 through the through holes. In this embodiment, the support rod 1 is used for... When the operator holds the flat steel grounding heat release mold 7 of the corresponding size, it is placed between the clamping plates 2 and connected to several heat-conducting rods 9 and positioning rods 10 through the through holes on the flat steel grounding heat release mold 7. In this embodiment, the positioning rods 10 are fixedly connected in pairs to the upper and lower parts of the side of the support rod 1, respectively, to fix the grounding heat release mold 7 and prevent the mold from shifting under the thermite heating. At the same time, the heat-conducting rods 9 are also embedded in pairs to the inside of the flat steel grounding heat release mold 7 and contact the inside of the flat steel grounding heat release mold 7. When in use, the flat steel grounding heat release mold 7 can be further reinforced with bolts to make it more secure.

[0021] Preferably, the support rod 1 is provided with a diagonal brace 3 for supporting the clamping plate 2, and the diagonal brace 3 is used to further reinforce the clamping plate 2 to prevent the clamping plate from loosening.

[0022] Preferably, an end sleeve 6 is provided on the support rod 1 at the end position to protect the staff from burns when holding the support rod 1.

[0023] Preferably, the bolt group includes a bolt 4 that passes vertically through any of the clamping plates 2. A rotating head 5 is provided on the end of the bolt 4 away from the flat steel grounding heat dissipation mold 7. The bolt 4 can be tightened by rotating the head 5 during use. The rotating head 5 is made of heat-insulating material such as cork.

[0024] Preferably, a hinge 1-1 is provided on the support rod 1 at the middle position. The hinge 1-1 divides the support rod 1 into upper and lower parts. In use, the upper and lower parts of the mold are respectively installed on the upper and lower parts of the support rod 1, fixed, and then assembled by rotating the support rod 1.
