Description

Technical Field

[0001] The utility model relates to the technical field of bridge frames, in particular to a safety bridge frame with arc protection function. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type and grid type. Cable trays in buildings can be erected independently or attached to various buildings (structures) and pipe gallery supports. They should have the characteristics of simple structure, beautiful shape, flexible configuration and easy maintenance.

Finally, the high temperature will cause the insulation layer to burn and carbonize, resulting in short circuits, electric arcs, and even fires.

[0004] Therefore, it is necessary to propose a safety bridge with arc protection function to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 to Figure 5 A safety bridge with arc protection function shown in the figure includes a frame support 1 and a frame cover 2. The frame cover 2 is fixedly mounted on the frame support 1 by screws 3. In order to improve the heat dissipation effect of the bridge, a plurality of heat dissipation holes 17 are provided on the side wall of the frame support 1. An insulating rod 4 is arranged inside the frame support 1. The insulating rod 4 is arranged in plurality. The plurality of insulating rods 4 are equally spaced and fixedly connected to the frame support 1. A bottom plate 5 is fixedly connected to the top of the insulating rod 4. A lower arc groove 6 is provided on the upper surface of the bottom plate 5. A horizontal plate 10 is arranged above the bottom plate 5. The horizontal plate 10 abuts against the frame cover 2. A top plate 11 is arranged between the bottom plate 5 and the horizontal plate 10. Slide rods 14 are slidably penetrated at both ends of the top plate 11. The top of the slide rod 14 is fixedly connected to the horizontal plate 10. A spring 15 is sheathed on the outside of the slide rod 14, one end of the spring 15 is fixedly connected to the cross plate 10, and the other end of the spring 15 is fixedly connected to the top plate 11. An upper arc groove 12 is provided on the lower surface of the top plate 11, and the upper arc groove 12 is distributed correspondingly to the lower arc groove 6, and the cable is positioned between the upper arc groove 12 and the lower arc groove 6.

[0025] The lower arc groove 6 and the upper arc groove 12 are both provided in plurality, and multiple cables can be placed at the same time, and there is a certain gap between two adjacent cables to avoid stacking and interweaving of the cables, so that heat is not transferred to each other.

[0026] When in use, the cables are positioned between the upper arc groove 12 and the lower arc groove 6, so that multiple cables are arranged in order and will not be randomly stacked and interwoven. When a large current passes through one of the cables and generates heat, it will not be transmitted to other cables, thereby avoiding short circuits, arcs, etc., so that the bridge has the functions of preventing short circuits and arcs.

[0027] Insulating rods 4 are provided to elevate the bottom plate 5 so that the cables are suspended in the air, which is beneficial to the heat dissipation of the cables and improves the safety performance of the bridge frame.

[0028] In addition, the bottom plate 5 and the horizontal plate 10 can be made of insulating materials and are not easy to conduct heat.

[0029] To avoid abrasion of the cable, a lower rubber pad 7 is fixedly connected to the interior of the lower arc groove 6, and an upper rubber pad 13 is fixedly connected to the interior of the upper arc groove 12, and both the lower rubber pad 7 and the upper rubber pad 13 have an insulating effect. The cable is clamped and positioned between the lower rubber pad 7 and the upper rubber pad 13, and the lower rubber pad 7 and the upper rubber pad 13 can prevent abrasion of the cable and extend its service life.

[0030] In order to expand the contact area between the slide bar 14 and the bottom plate 5 and improve the stability of the safety bridge, a round block 16 is fixedly connected to the bottom of the slide bar 14 , and the round block 16 abuts against the bottom plate 5 .

[0031] The upper surface of the horizontal plate 10 is fixedly connected with an insert block 9, and the frame cover 2 is provided with a slot 8 that is plugged with the insert block 9. The insert block 9 and the slot 8 are provided, and structures such as the top plate 11 and the slide bar 14 can be selectively installed to improve the flexibility of the bridge frame.

[0032] When working, insert the plug block 9 into the slot 8, put the cable into the bracket 1 and place it on the lower rubber pad 7, put the bracket cover 2 on the bracket 1, and move it from top to bottom to fit it on the top of the bracket 1. During the movement, the upper rubber pad 13 fits on the top of the cable. As the bracket cover 2 moves, the top plate 11 slides upward on the slide bar 14 and squeezes the spring 15 to shrink. The restoring elastic force of the spring 15 squeezes the upper rubber pad 13 on the cable through the top plate 11 to prevent the cable from sliding randomly. At the same time, the elastic structure also prevents the top plate 11 from excessively squeezing the cable, and it is suitable for cables of various models.
