During the hoisting installation process, the bus duct is hoisted and fixed by using hanging rails and crossarms. However, there is no connection structure between the traditional crossarm and the bus duct. The bus duct is only laid on the crossarm and connected with rigid contact. During the long-term use, the stress record at the contact point between the crossarm and the bus duct can easily cause external extrusion damage to the bus duct, and the middle part of the bus duct that is not in contact with the crossarm will bend.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 , the present invention provides a technical solution:

[0030] A bus duct transversely mounted flexible bracket comprises two groups of symmetrically distributed cross arms 1, the upper end surfaces of the cross arms 1 are symmetrically provided with hanging rails 2, and the hanging rails 2 are fixed to the cross arms 1 by bolts, the upper end surfaces of the two cross arms 1 are symmetrically provided with bus duct bodies 4, and two fixing structures are provided between the two bus duct bodies 4;

[0031] A rubber ring 3 is sleeved on the lower side of the outer surface of the two hanging rails 2, and a transmission structure is arranged inside the cross arm 1. The transmission structure controls the expansion displacement of the two fixed structures to realize the extrusion fixation and force support of the bus duct body 4.

[0032] Specifically, if Figure 2 and Figure 4 As shown, the fixed structure includes an extrusion plate 7, a connecting plate 17 vertically fixed to the extrusion plate, and a supporting plate 6 vertically fixed to the connecting plate 17. The extrusion plate 7, the connecting plate 17 and the supporting plate 6 are designed in a Z-shaped structure. The side plate of the extrusion plate 7 is in contact with the outside of the bus duct body 4, and the lower end surface of the supporting plate 6 is located on the lower end surface of the bus duct body 4. The two ends of the extrusion plate 7 are located on the upper end surface of the cross arm 1 and are transmission-connected to the transmission structure in the cross arm 1. The two fixed structures are exactly the same.

[0033] Specifically, if Figure 1 As shown, the rubber ring 3 is a cylindrical hard rubber sleeved on the outside of the hanging rail 2 and a hollow structure sleeved on the outside of the hanging rail 2, and an air injection valve is fixed on the outside of the hollow structure rubber ring 3.

[0034] By adopting the above technical solution, the bottom supporting plate 6 also moves during the displacement of the extrusion plate 1 7 and the extrusion plate 2 8, thereby supporting and fixing the bottom of the bus duct body 4, thereby achieving force sharing between the bus duct and the cross arm 1, thereby reducing the risk of bending and damage of the bus duct body 4 due to uneven force due to its own weight during long-term use.

[0035] Specifically, if Figure 5 and Figure 6 As shown, the transmission structure includes an active cavity 9 opened inside the cross arm 1, a gear 16 is rotatably connected at a position between two fixed structures in the active cavity 9, a transmission rod 5 is fixedly connected through the gears 16 in the two cross arms 1, and the transmission rod 5 is rotatably connected to the cross arm 1, and both ends of the transmission rod 5 are located outside the cross arm 1 and are designed to be threaded, an upper tooth plate 15 and a lower tooth plate 14 are respectively provided on the upper and lower sides of the gear 16 in the active cavity 9, and the gear 16 is meshed and transmission-connected with the upper tooth plate 15 and the lower tooth plate 14, A slide groove 10 and a slide groove 2 11 are respectively provided on the upper end surface of the cross arm 1 at positions corresponding to the fixed structure, and a slider 12 and a slider 2 13 are respectively slidably connected inside the slide groove 10 and the slide groove 2 11, and the top of the slider 12 is fixed to one end of the extrusion plate 17 through the slide groove 10, and the bottom of the slider 12 is fixedly connected to the upper tooth plate 15, and one end of the lower tooth plate 14 is fixedly connected to the slider 2 13, and the top of the slider 2 13 is fixedly connected to the extrusion plate 2 8 of another fixed structure through the slide groove 2 11.

[0036] By adopting the above technical solution, the user drives the transmission rod 5 to rotate counterclockwise through an external driving device, and at this time drives the upper tooth plate 15 and the lower tooth plate 14 to move and displace to both sides in the installation cavity, thereby driving the slider 12 and the slider 2 13 to be located inside the slide groove 10 and the slide groove 2 11. At this time, the upper end surface of the cross arm 1 and the extrusion plate 1 7 and the extrusion plate 2 8 fixed with the slider 12 and the slider 2 13 are displaced together, and then the side plates of the extrusion plate 1 7 and the extrusion plate 2 8 push and squeeze the bus duct body 4, and during the displacement of the extrusion plate 1 7 and the extrusion plate 2 8, the bottom supporting plate 6 also displaces, supporting and fixing the bottom of the bus duct body 4, realizing force sharing of the bus duct and the cross arm 1, thereby reducing the risk of bending and damage of the bus duct body 4 due to uneven force due to its own weight during long-term use.

[0037] Working principle: During operation, the user first places the bus duct body 4 between the two fixed structures and the hanging rail 2, and then the user selects different types of rubber rings 3 according to the on-site usage conditions. The rubber ring 3 made of hard rubber has flexible contact fixation and corrosion and oxidation resistance, while the rubber ring 3 with a hollow structure has better expansion and expansion properties, and can cooperate with the clamping and fixing of the bus duct body 4 of smaller size. Then the user drives the transmission rod 5 to rotate counterclockwise through an external driving device, and at this time drives the upper tooth plate 15 and the lower tooth plate 14 to move and displace to both sides in the installation cavity, thereby driving the slider 1 12 and the slider 2 13 to be located inside the slide groove 10 and the slide groove 2 11. At this time, the upper end surface of the cross arm 1 and the extrusion plate 1 7 and the extrusion plate 2 8 fixed to the slider 1 12 and the slider 2 13 are displaced together, and then the side plates of the extrusion plate 1 7 and the extrusion plate 2 8 push and squeeze the bus duct body 4, and cooperate with the rubber ring 3 to flexibly clamp and fix the bus duct body 4, and can clamp and fix bus duct bodies 4 of different sizes;

[0038] After the adjustment is completed, bolts are installed on the exposed ends of the transmission rod 5 to fix them;

[0039] During the displacement of the extrusion plate 1 7 and the extrusion plate 2 8 , the bottom supporting plate 6 also displaces to support and fix the bottom of the bus duct body 4 , thereby achieving force sharing between the bus duct and the cross arm 1 , thereby reducing the risk of bending and damage of the bus duct body 4 due to uneven force due to its own weight during long-term use.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
