Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a rigid hanger of a pedestrian suspension bridge. Background Art

[0002] A suspension bridge, also known as a suspension bridge, is a bridge whose main load-bearing superstructure consists of cables (or steel chains) suspended from towers and anchored on both banks (or at both ends of the bridge). The cable geometry is determined by the equilibrium of forces and is generally close to a parabola. Numerous hangers are suspended from the cables, suspending the bridge deck. Stiffening beams are often installed between the deck and the hangers, forming a combined system with the cables to reduce deflection caused by loads. Rigid hangers on pedestrian suspension bridges are typically used to support the deck and connect the cable system. These hangers are typically made of high-strength steel to ensure they bear the loads of the deck and pedestrians, improving the safety and stability of the suspension bridge while ensuring pedestrian comfort.

[0003] In actual use, it is inconvenient to adjust the length of the rigid hanger of the existing pedestrian suspension bridge during installation, and it is difficult for personnel to install and debug it in time.

[0004] After searching the existing patent: Pedestrian Suspension Bridge Rigid Suspension Rod (Publication No.: CN213571494U), it was found that existing wire rope slings or rigid pull rod slings are equipped with anchor heads at both ends, with the upper end anchored to the main cable clamp and the lower end anchored to the main beam. If the existing technology is applied to short slings less than 1m in length, the anchor heads at both ends will occupy more than 2 / 3 of the length and cost, and the cable body itself will be used in small quantities, which will greatly increase the manufacturing cycle and production cost of the entire bridge. The utility model includes a flat plate, a pin shaft, a pin hole, and a ventilation hole. A pin hole is provided at each end of the flat plate, and a pin shaft is installed in each pin hole. The pin shaft and the flat plate are connected, and the ventilation hole is provided in the middle of the flat plate. The rigid suspender of the pedestrian suspension bridge adopts a plate structure without anchor heads, which significantly simplifies the preparation process of existing slings, greatly saves production cycle and manufacturing cost, and improves the overall rigidity and durability of the sling.

[0005] Although the above patent adopts a plate structure without anchor heads, which significantly simplifies the preparation process of existing slings, greatly saves production cycle and manufacturing costs, and improves the overall stiffness and durability of the slings, it is not convenient for buffering and shock absorption, and wind or collision vibrations can easily cause damage to the rigid boom connection.

[0006] Therefore, it is necessary to invent a rigid hanger for a pedestrian suspension bridge to solve the above problems. Utility Model Content

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rigid hanger for a pedestrian suspension bridge, comprising a rigid hanger body, the bottom end of the rigid hanger body is threadedly connected to a rotating sleeve, the bottom of the rotating sleeve is threadedly connected to a connecting rod, the top of the rigid hanger body and the bottom of the connecting rod are fixedly connected to a connecting joint, one end of the connecting joint is fixedly connected to a buffer assembly, the surface of the connecting joint is slidingly connected to a fixed sleeve, one end of the fixed sleeve is fixedly connected to a support rod, one end of the support rod is fixedly connected to a rotating bolt, one group of the rotating bolts is rotatably connected to a rotating piece, the top surface of the rotating piece is fixedly connected to a lower ring, one side of the lower ring is rotatably connected to an upper ring, and one side of the upper ring is rotatably connected to several groups of mounting components.

[0009] As a further solution of the present invention, the buffer assembly includes a damping hydraulic rod fixedly connected to one end of the connecting joint, and a buffer spring is sleeved on the surface of the damping hydraulic rod, which is convenient for offsetting part of the vibration pressure.

[0010] As a further solution of the present invention, the mounting assembly includes a rotating rod rotatably connected to one side of the upper collar, a threaded rod is sleeved on the surface of the rotating rod, and a limiting nut is threadedly connected to the bottom of the threaded rod. The limiting nut is convenient for rotating on the surface of the threaded rod and squeezing the bottom surface of the lower collar.

[0011] As a further solution of the present invention, threaded holes are provided on the top and bottom of the rotating sleeve, and a threaded bolt passes through the inside of the threaded hole. The surfaces of the rigid hanger body and the connecting rod are axially equidistantly provided with limiting holes that are compatible with the threaded bolt.
