[0040] The embodiment provides a cable bridge support, a cable support mechanism and a transformer assembly. The transformer assembly comprises a transformer and the cable support mechanism, the cable support mechanism is installed on the transformer, and the cable of the transformer is supported in the cable support mechanism. The cable support mechanism not only facilitates safe and orderly laying of the cable, but also avoids damage of the cable caused by extrusion, friction or dampness and the like, thereby ensuring stable operation of the entire electrical system.

[0041] Hereinafter, the specific details of the cable support mechanism are introduced by taking the cable of the cable support mechanism for supporting the transformer as an example. It can be understood that in other embodiments, the cable support mechanism can also be applied to other scenes requiring cable support, which is not limited herein.

[0042] The cable support mechanism comprises a cable bridge and a cable bridge support, wherein the cable bridge support is installed on the transformer, and optionally, the cable bridge support is installed on the oil tank cover of the transformer. The cable bridge is installed on the cable bridge support, and the cable of the transformer is installed in the cable bridge. The cable bridge is provided with a mounting hole for fixing the cable bridge on the cable bridge support. Without departing from the inventive concept of the present application, the cable bridge can be any one of the prior art.

[0043] As shown in Figures 1-3 , the cable bridge support comprises a support assembly 1, a positioning nail 2 and an elastic member 3. The support assembly 1 is provided with a mounting portion 111 for cooperating with the mounting hole of the cable bridge, the positioning nail 2 is in sliding cooperation with the support assembly 1, and the elastic member 3 is arranged between the support assembly 1 and the positioning nail 2. The elastic member 3 is configured to enable the lower end of the positioning nail 2 to extend out of the support assembly 1 in a free state, and to retract into the support assembly 1 when the lower end of the positioning nail 2 is subjected to an external force. As shown in Figure 2 , when the cable bridge support is not installed on the transformer, the elastic member 3 remains in an uncompressed or slightly compressed state, thereby providing a pre-tightening force for the positioning nail 2 and stably maintaining the lower end of the positioning nail 2 in a state of extending out of the support assembly 1. Therefore, during the positioning of the support, the operator can conveniently and accurately align the positioning nail 2 with the mark point drawn on the installation part (i.e. the transformer), thereby ensuring the accuracy of the installation position of the entire cable bridge support. On the one hand, the position accuracy of the mounting portion 111 on the support assembly 1 is ensured, i.e. the coaxiality of the mounting portion 111 and the mounting hole on the cable bridge is ensured. On the other hand, for the scene where multiple cable bridge supports support the cable bridge, the straightness of the arrangement of the multiple cable bridge supports can be ensured, thereby ensuring accurate and firm installation of the cable bridge. In addition, as shown in Figure 3As shown, in the process of welding and fixing the support assembly 1 with the installation site, the positioning nail 2 is retracted into the support assembly 1 under external force, avoiding interference of the positioning nail 2 with the welding process, and the elastic member 3 can also absorb the vibration and stress generated in the welding process to some extent, improving the welding quality of the support assembly 1.

[0044] As shown in the figure, Figure 1 The mounting portion 111 includes at least one circular through hole. Based on the accurate positioning of the support assembly 1, the mounting portion 111 is provided as a circular through hole, which can ensure that the mounting hole on the cable bridge is aligned, thereby improving the processing convenience of the support assembly 1 and reducing the manufacturing cost. Alternatively, in the present embodiment, two circular through holes are provided on the support assembly 1, and in other embodiments, the specific number of circular through holes can be flexibly set according to needs, which is not limited here.

[0045] As shown in the figure, Figures 2-4 The support assembly 1 includes a support plate 11 and a support pipe 12, the mounting portion 111 is provided on the support plate 11, and the support pipe 12 is installed on the lower side of the support plate 11, and the support pipe 12 is used for welding with the transformer. In the present embodiment, the support pipe 12 is a hollow structure, which on the one hand forms a containing space for the elastic member 3 and the positioning nail 2, and on the other hand plays a role in reducing the weight of the support assembly 1, thereby improving the installation convenience of the support assembly 1.

[0046] As shown in the figure, Figure 3 and Figure 4 The support assembly 1 is provided with a slide 10, the slide 10 has oppositely arranged top plate 101 and baffle 122, the upper end of the positioning nail 2 is arranged in the slide 10 and can slide between the top plate 101 and the baffle 122, the lower end of the positioning nail 2 penetrates the baffle 122, the elastic member 3 is arranged in the slide 10, and the first end is connected with the top plate 101 or the baffle 122, and the second end is connected with the positioning nail 2. The top plate 101 and the baffle 122 of the slide 10 not only limit the sliding stroke of the positioning nail 2 to avoid the positioning nail 2 from falling out of the support assembly 1, but also play a containing role for the elastic member 3, ensuring smooth installation of the elastic member 3 and avoiding damage to the elastic member 3.

[0047] Specifically, the support tube 12 comprises a tube body 121 configured as a tubular with both ends open and the above-mentioned baffle 122, the support plate 11 is installed at the upper end of the tube body 121 and blocks the upper end opening of the tube body 121, and the baffle 122 is installed in the tube body 121 and arranged opposite to the support plate 11, and the baffle 122 is provided with a through hole 1221 for the positioning nail 2 to pass through. In this way, the support plate 11, the tube body 121 and the baffle 122 are surrounded to form the slide 10, and the area opposite to the upper end of the tube body 121 of the support plate 11 is the top plate 101 of the slide 10. In this embodiment, the support tube 12 and the support plate 11 are arranged in a split structure, which facilitates the installation of the elastic member 3 and the positioning nail 2 in the slide 10. Alternatively, the tube body 121 and the support plate 11 can be fixed by welding, fastener connection or the like, and the baffle 122 and the tube body 121 can also be fixed by welding, fastener connection or the like, which is not limited here.

[0048] As shown in Figure 3 and Figure 5 , the positioning nail 2 comprises a nail body 21 and a connecting plate 22, the connecting plate 22 is connected with the upper end of the nail body 21 and arranged in the slide 10, the lower end of the nail body 21 passes through the through hole 1221 on the baffle 122, and the second end of the elastic member 3 abuts against the connecting plate 22. In this embodiment, the cross-sectional area of the connecting plate 22 is larger than the cross-sectional area of the nail body 21 and larger than the cross-sectional area of the through hole 1221, as shown in Figure 2 , when the positioning nail 2 is not subjected to external force, the connecting plate 22 is in contact with the baffle 122, so that the support assembly 1 stably supports the positioning nail 2 and limits the positioning nail 2, avoiding the positioning nail 2 from falling out of the support assembly 1. As shown in Figure 3 , when the positioning nail 2 contacts the oil tank cover of the transformer, the connecting plate 22 extrudes the elastic member 3 and forms a gap between the connecting plate 22 and the baffle 122, so that the positioning nail 2 is retracted into the tube body 121, ensuring that the support assembly 1 is successfully welded with the oil tank cover of the transformer. In addition, the connecting plate 22 facilitates the connection between the elastic member 3 and the positioning nail 2. In this embodiment, the lower end of the nail body 21 (i.e. the lower end of the positioning nail 2) is configured in a sharp form, which facilitates the alignment of the mark point on the oil tank cover of the transformer during the installation of the cable bridge support, so as to quickly determine the accurate position of the cable bridge support.

[0049] Alternatively, as shown in Figure 2As shown, in this embodiment, the elastic element 3 is a spring, with its first end abutting against the top plate 101 and its second end abutting against the connecting plate 22. When the positioning pin 2 is not subjected to external force, the spring is in its original length or slightly compressed state, keeping the lower end of the positioning pin 2 extended outside the support assembly 1. In other embodiments (not shown), the elastic element 3 can also be a tension spring, with one end connected to the baffle 122 and the other end connected to the connecting plate 22. When the positioning pin 2 is not subjected to external force, the tension spring is in its original length state, thereby keeping the lower end of the positioning pin 2 extended outside the support assembly 1.

[0050] like Figure 3 and Figure 4 As shown, in some embodiments, the cross-section of the through hole 1221 has the same shape and size as the cross-section of the nail body 21. This arrangement ensures the coaxiality of the positioning nail 2 with the support tube 12 after it is installed in the support assembly 1, thereby effectively preventing positioning deviation. It also guides the positioning nail 2 as it slides along the slide rail 10, preventing deviation in the sliding direction of the positioning nail 2. In this embodiment, the cross-sectional shape of both the through hole 1221 and the nail body 21 is circular. In other embodiments, the cross-sectional shape of the through hole 1221 and the positioning nail 2 can also be quadrilateral, etc., and is not specifically limited here.

[0051] like Figure 3 As shown, in some embodiments, the cross-section of the connecting plate 22 has the same shape and size as the cross-section of the slide rail 10. Therefore, the cooperation between the connecting plate 22 and the sidewall of the slide rail 10 can further guide the positioning pin 2 during its sliding process in the slide rail 10, ensuring the coaxiality of the support assembly 1 and the positioning pin 2. In this embodiment, the cross-sectional shape of both the connecting plate 22 and the slide rail 10 is circular. In other embodiments, the cross-sectional shape of the connecting plate 22 and the slide rail 10 can also be set as quadrilateral, etc., and no specific limitation is made here.

[0052] It is understood that in some embodiments, the cross-section of the through hole 1221 and the cross-section of the nail body 21 need not be the same in shape and size, and the cross-section of the connecting plate 22 and the cross-section of the slide 10 need not be the same in shape and size, in order to guide the movement direction of the positioning nail 2:

[0053] In some embodiments, such as Figures 3-5As shown, the top plate 101 is provided with a guide column 13 at the lower side, and the upper end of the positioning pin 2 is provided with a guide groove 211, and the guide column 13 is inserted into the guide groove 211 and is in sliding fit with the guide groove 211. Through the fit of the guide column 13 and the guide groove 211, the positioning pin 2 can be stably guided during the sliding process in the slide 10, and the coaxiality of the support assembly 1 and the positioning pin 2 is ensured. In the embodiment, the entire pin body 21 can be provided with a hollow structure, which on the one hand forms the guide groove 211, and on the other hand can also play a role in weight reduction. In the embodiment, the guide column 13 can be connected with the top plate 101 through welding, threaded connection, fastener connection and the like.

[0054] In some embodiments (not shown), the top plate 101 is provided with a guide column 13 at the lower side, and the lower end of the guide column 13 is provided with a guide sliding groove, and the upper end of the positioning pin 2 is inserted into the guide sliding groove and is in sliding fit with the guide groove. Through the fit of the positioning pin 2 and the guide sliding groove, the positioning pin 2 can also be stably guided during the sliding process in the slide 10, and the coaxiality of the support assembly 1 and the positioning pin 2 is ensured.

[0055] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, according to the idea of the utility model, the specific embodiments and application range will be changed, and the content of the specification should not be understood as the limitation of the utility model.
