A seismic-resistant ladder-type cable tray

Abstract

The present invention discloses an earthquake-resistant ladder-type cable bridge, belonging to the technical field of cable bridges, comprising a fixing plate, a fixing rod being fixed on the fixing plate, a concave piece being provided at the top end of the fixing rod, and a suspension device being provided on a side of the fixing plate away from the fixing rod. The earthquake-resistant ladder-type cable bridge is slidably connected with a T-shaped block in a placement groove through a T-shaped slot on the limit plate, so that the fixing component can be clamped on the fixing plate, and the fixing component can be disassembled and installed conveniently. Through a first electric push rod, the limit frame can be pushed to slide in a slide rail, thereby limiting the rotation of the rotating rod. Through the entire suspension device, the stability of the ladder-type cable bridge can be maintained when no earthquake occurs. After an earthquake occurs, in order to prevent the structure of the ladder-type cable bridge from being damaged due to excessive amplitude, the ladder-type cable bridge can swing within a certain range following the vibration, thereby reducing damage to the bridge caused by the connection being too firm.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention uses a T-slot on the limit plate to slide with a T-block in the placement slot, so that the fixing assembly can be clamped on the fixing plate and the fixing assembly can be disassembled and installed. The first electric push rod can push the limit frame to slide in the slide rail, thereby limiting the rotation of the rotating rod.

The entire suspension device can maintain the stability of the ladder cable bridge when no earthquake occurs.

[0018] 2.

[0019] 3. The present invention facilitates the clamping of the limit ring onto the rotating rod by rotating the connecting rod. Since the two limit rings are both semicircular ring structures, the limit rings can completely clamp and fix the rotating rod when clamped onto the rotating rod, preventing the rotating rod and the bottom block from rotating relative to each other, thereby fixing the position of the bottom block and maintaining the stability of the rotating assembly.

[0034] Among them, the limiting assembly 17 includes a fixed block 18, a first electric push rod 19 is fixed on the fixed block 18, slide rails 20 are provided on both sides of the limiting plate 11, a cross bar 21 is fixed at the output end of the first electric push rod 19, and a limit frame 22 is bolted to one end of the cross bar 21 away from the first electric push rod 19, and the symmetrical two ends of the limit frame 22 are respectively slidably connected in the corresponding slide rails 20.

[0035] At the same time, one end of the limit plate 11 away from the fixed block 18 is rotatably connected to a rotating component 23, and the rotating component 23 includes a rotating rod 24, the top of the rotating rod 24 is rotatably connected to the limit plate 11, and the bottom of the rotating rod 24 is rotatably connected to a rotating block 25, the bottom of the rotating block 25 is rotatably connected to a first C-shaped block 26, the bottom of the first C-shaped block 26 is fixedly connected to a first gear 27, the end of the first gear 27 away from the first C-shaped block 26 is rotatably connected to a support column 28, the first gear 27 is rotatably connected to the support column 28, a bottom block 29 is fixed to the bottom of the support column 28, and a bracket 30 is fixed to the bottom end of the bottom block 29.

[0036] A protrusion 31 is provided in the middle of the bracket 30 , a motor 32 is fixed on the protrusion 31 , an output end of the motor 32 is rotatably connected to a second gear 33 , and the first gear 27 is meshedly connected to the second gear 33 .

[0037] At the same time, both symmetrical ends of the bottom block 29 are rotatably connected with connecting rods 34, and the end of the connecting rod 34 away from the bottom block 29 is rotatably connected with a limit ring 35, and the limit rings 35 are respectively clamped on the symmetrical sides of the rotating rod 24 close to the rotating block 25.

[0040] Firstly, during an earthquake, the spring 6 senses the vibration and drives the suspension rod 7 to swing, and the induction plate 9 senses the impact from the collision hammer 8, so that the first electric push rod 19 pulls up the limit frame 22, and the connecting rod 34 rotates under the push of the second electric push rod 37, and the limit ring 35 opens from the rotating rod 24, releasing the position restriction of the limit ring 35 on the rotating rod 24, so that this ladder-type cable tray can respond to earthquakes, reduce the damage and impact of the shaking of the building caused by the earthquake on the cable tray structure, and improve the service life of the cable tray.

[0041] See also Figure 2 , Figure 3 , Figure 7 and Figure 8 When no earthquake occurs: the limit frame 22 slides to the lowest end of the slide rail 20 under the support of the first electric push rod 19, thereby limiting the position of the rotating rod 24 and preventing the rotating rod 24 from rotating on the limit plate 11, thereby ensuring the top installation stability of this ladder-type cable tray.

[0042] See also Figure 4 , Figure 5 , Figure 6 and Fig. 9 When an earthquake occurs: first, the second electric push rod 37 pushes the connecting rod 24 to rotate, and the connecting rod 34 drives the limiting ring 35 to leave the rotating rod 24, and the rotating rod 24 loses the position limit of the limiting ring 35, so that the bottom block 29 and the rotating rod 24 can swing, and at the same time, the motor 32 drives the second gear 33 and the first gear 27 to rotate, and the first gear 27 makes the first U-shaped block 26 and the rotating block 25 rotate, thereby adjusting the swinging direction of the bottom block 29 and the rotating rod 24, so that the entire rotating assembly 23 swings with the vibration and floating of the floor, preventing damage to the cable tray due to the overly fixed connection between the cable tray and the floor.
