Problems solved by technology

The inventors found that because the horizontal metal rods severely restrict the lateral space, it is very inconvenient for the car to open and close the door and the movement of the operator, which greatly reduces the work efficiency and increases the risk of falling
The pin connection between the rotating rod and the rotating rod seat, the lateral clearance of the railing is reduced by setting the washer to reduce the lateral shaking of the railing, but the effect is not ideal, the railing shakes greatly or the resistance force is too large, and a spring assist is required

Abstract

The invention discloses a foldable protective guard, application and a specialized railway wagon for automobile transportation. The foldable protective guard comprises at least one group of protectiveassemblies, each protective assembly comprises a first rod which is transversely arranged, each first rod is hinged to multiple second rods, and first soft ropes are connected among the second rods;and the sides of the second rods are connected with locking devices, the locking devices comprise sliding locking plates hinged to the second rods, the sliding locking plates are provided with slidinggrooves, fixing shafts are arranged in the sliding grooves and can slide along the sliding grooves, the fixing shafts are fixedly connected with fixing seat plates, and the locking devices can drivethe second rods to be switched between an oblique state and a vertical state and lock or unlock the positions of the second rods in the two states.

Description

technical field [0001] The disclosure relates to a foldable protective fence, which can be applied to various car bodies, and is especially suitable to be used in a railway wagon for transporting automobiles. Background technique [0002] Railway transportation has the characteristics of safety, energy saving, and environmental protection, while automobile production and consumption have obvious regional concentration, and most of them are medium and long-distance transportation, which is in line with the technical and economic characteristics of large-capacity, long-distance, and large-scale railways. Therefore, the transportation of automobiles Special vehicles for railway wagons are widely used in Europe. [0003] Due to the limitation of the vehicle limit, the height of the upper protective fence of the railway freight car special vehicle for transporting cars is limited, and the fixed protective fence is difficult to meet the protection height requirements. After long-...
