The middle frame is in an I-shaped structure formed by combining parts such as a tension spring, a tightening rope, a roller and the like, the centering force can not completely offset the inertia force of the middle frame, the middle frame can shake back and forth and swing left and right due to the inertia of the middle frame, even torsion and deflection are caused, friction and collision between the middle frame and a connecting piece and between other parts are easy to cause hidden danger to the personal safety of passengers and the running safety of vehicles, and meanwhile, the through channel is easy to cause damage such as pull-out, bruise and the like. Therefore, the centering device for the through channel is developed, and the centering device is simple in structure and high in reliability, and continuously provides balanced tension to meet the requirements of various working conditions.
The invention comprises the following steps:
The invention aims to overcome the defects of the prior art, and provides a centering device for a through channel, which ensures that a connecting body can meet the requirements of safety and reliability when a vehicle moves in various ways and avoids the phenomena of shaking the connecting body back and forth and swinging the connecting body left and right.
In order to achieve the above purpose, the main structure of the centering device for the through channel comprises an adjusting rod, an end socket, locking pieces, joints, a protective cover, small installation seats, screw assemblies, baffle rings and large installation seats, wherein two ends of the adjusting rod are respectively connected with the end socket, the locking pieces are arranged between the adjusting rod and the end socket, the joints are arranged in the end socket, the protective covers are arranged at the upper end and the lower end of the joints, one ends of the small installation seats extend into the joints and the protective cover and are connected with the end socket through the screw assemblies and the baffle rings, and one small installation seat is connected with the large installation seat.
The small mounting seat is connected with the large mounting seat through the bolt component.
The invention relates to a small mounting seat, wherein mounting holes are formed at two side wing plates of the small mounting seat and two ends of the large mounting seat.
Compared with the prior art, the invention has the advantages that the large mounting seat and the small mounting seat in the free state are respectively fixedly connected with the middle frame and the connecting body (the vehicle body frame), can be mounted at different positions of the frame body according to the requirement, play a role in centering or positioning, have strong adaptability, can enable the through passage to meet various movement requirements of a vehicle, improve the comfort level of a train, have simple manufacturing process and compact structure, are convenient to mount, can meet the requirements of complex working conditions without increasing the external dimension, reduce the working space, improve the curve passing capacity of the through passage, realize the modularized design of the through passage, and reduce the manufacturing and maintenance cost.
