Technical Field

The invention relates to the technical field of cable bridges, in particular to an impact-resistant combined cable bridge.

Background Art

Cable trays are divided into trough-type, tray-type, ladder-type and grid-type structures, and are composed of brackets, supports and installation accessories. The cable trays in buildings can be erected independently or attached to various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts must be galvanized. For cable trays installed in the open air outside the building, if they are near the seaside or in a corrosion zone, the material must be anti-corrosive and moisture-resistant. The modular cable tray is the second generation of cable trays. It is suitable for various projects, units and the laying of various cables. It has the characteristics of simple structure, flexible configuration, easy installation and novel form. The existing modular cable trays have a single function and cannot separate the cables. The heat dissipation effect is poor, which easily leads to a large amount of heat accumulation between the cables, affecting the service life of the cables. In addition, the impact resistance is poor, which easily causes internal cable pulling. The modular cable tray is easily deformed, affecting the service life. For this reason, we propose an impact-resistant modular cable tray to solve the above defects.

3. The second buffer assembly provides buffering protection for the frame in the horizontal direction. When the frame is impacted by an external force in the horizontal direction on the right side, the frame becomes farther away from the right side plate of the support plate, and the angles between the first connecting rod and the second connecting rod on the right side and the horizontal direction become smaller. The lower end of the second connecting rod drives the slider to slide upward in the dovetail groove. At this time, the second spring on the right side is squeezed, and the elastic force of the second spring itself applies a reverse force to the first connecting rod and the second connecting rod on the right side, which buffers the frame while preventing the frame from moving excessively to the left, thereby providing buffering protection for the frame in the horizontal direction and improving its impact resistance.

The placement plate 62 can separate each cable separately to avoid contact and extrusion that affect the heat dissipation effect. After the cable is laid, the positioning pin 201 is aligned with the positioning hole 301, and the upper cover 3 is pressed downward to make the card strip 202 engage with the card groove 302 of the upper cover 3, so as to fix the upper cover 3 to prevent relative sliding.

The first buffer assembly 4: The array is arranged on the lower surface of the frame 2, and the first buffer assembly 4 includes a guide rod 41, a slip ring 42, a connecting rod 43 and a first spring 44. The upper end of the connecting rod 43 is rotatably connected to the inside of the U-shaped connector arranged on the lower surface of the rectangular groove 7 through a pin shaft, and the lower end of the connecting rod 43 is rotatably connected to the top of the slip ring 42 through a pin shaft.
