Description

Technical Field

[0001] This utility model relates to the field of contact wire accessories technology, and in particular to a foldable AF line suspension combination column. Background Technology

[0002] In the overhead contact system of electrified railways and urban rail transit, the AF line (positive feeder) suspension column is a key component supporting and fixing the AF line. Traditional AF line suspension columns mostly adopt an integral structure, with the middle suspension rod and the upper and lower connecting parts integrally formed or welded. Although this structure can ensure a certain strength and stability, it occupies a lot of space during transportation, resulting in low loading capacity of transport vehicles and a significant increase in transportation costs. It also requires a large warehouse space for storage, making warehousing management inconvenient and increasing costs.

[0003] Furthermore, with the expansion of rail transit construction, the demand for AF line suspension composite bollards is increasing. However, the transportation and installation of traditional bollards are constrained by limited construction sites, affecting construction progress. Therefore, the development of a foldable AF line suspension bollard to save transportation and storage space and improve construction efficiency is an urgent practical need. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a foldable AF line suspension combination column to solve the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the present invention provides a foldable AF line suspension combination column, comprising: a U-shaped base and two suspension rods, one end of each suspension rod being connected to both ends of the U-shaped base, and the other end being respectively provided with a wire clamping seat and a flange seat. Guide shafts are provided at both ends of the U-shaped base. Each suspension rod has a strip-shaped sliding hole along its axial direction, and the guide shaft passes through the strip-shaped sliding hole. A semi-circular frustum is provided at an adjacent end of each of the two suspension rods. A radially extending groove is provided on the side of the semi-circular frustum. The groove is triangular, and when the two semi-circular frustums are joined, the two grooves form a square through hole. A wedge rod that cooperates with the groove is provided on the U-shaped base.

[0006] Furthermore, a guide rod is provided at the bottom of the U-shaped seat, and a pressure plate and a compression spring are provided on the guide rod. The compression spring keeps the pressure plate in contact with the U-shaped seat. Positioning plates are provided at both ends of the pressure plate, and positioning grooves that cooperate with the positioning plates are provided on the cylindrical surfaces of the semicircular platform and the hanging rod.

[0007] Furthermore, the U-shaped seat has a cover on its open side, and the two ends of the cover have limiting grooves that are adapted to the lifting rods. The lifting rods have radial locking grooves that cooperate with the wedge rods. When the two lifting rods are inserted into the limiting grooves, the locking grooves on the two rods are aligned.

[0008] Furthermore, the end of the boom connected to the flange seat is provided with a connecting groove and a locking pin. The cylindrical surface of the boom is provided with a rotating shaft passing through the connecting groove and a first locking hole. The rotating shaft and the first locking hole are symmetrically arranged about the axis of the boom. The flange seat is provided with a connecting plate that mates with the connecting groove. The connecting plate is provided with two symmetrical connecting holes. The distance between the two connecting holes is equal to the distance between the rotating shaft and the first locking hole. The rotating shaft is disposed in one of the connecting holes.

[0009] Furthermore, a second locking hole is provided on the rod above the rotating shaft, and the distance between the second locking hole and the rotating shaft is equal to the distance between the rotating shaft and the first locking hole.

[0010] Compared with the prior art, the beneficial effects of this utility model include:

[0011] 1. This utility model allows the two lifting rods to separate by pulling out the wedge rod and lifting the pressure plate. The lifting rods are then rotated around the guide shaft and engaged in the limiting groove, and locked in a folded state by the wedge rod. This design significantly reduces the space occupied by the lifting column. Compared to traditional non-foldable lifting columns, it reduces the volume occupied by vehicles or containers during transportation, lowering transportation costs. It also saves warehouse space during storage, improving space utilization and solving the problem of inconvenient transportation and storage of traditional lifting columns.

[0012] 2. This utility model uses two lifting rods connected by a guide shaft and a strip-shaped sliding hole. The wedge rod on the U-shaped seat is inserted into the square through hole formed by the splicing of two semi-circular truncated cones to achieve fixation. The lifting rods and the flange seat are connected by a rotating shaft and a locking pin. Different locking holes can also be selected as needed to ensure a stable connection in different states, effectively guaranteeing stability during transportation and use.
