Through channel with novel rapid tightening mechanism

Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to a through channel with a novel rapid tightening mechanism, a flexible body is arranged between a fixed side frame body and a movable side frame body, the closed end of the tightening mechanism of an inverted-U-shaped structure is connected with the fixed side frame body, and the open end of the tightening mechanism is connected with the movable side frame body; considering the operation requirement that vehicles are frequently coupled and decompiled, the device can be quickly and reliably folded through single-person operation, so that the tightening time of the through channel during decompilation is shortened, the labor intensity is reduced, the operation efficiency is improved, the maintenance cost is reduced, and the device can adapt to position change caused by relative movement between the vehicles during train coupling; and the through channel is simple in structure, convenient to operate, reliable in performance, easy to maintain, capable of meeting the requirement for continuous development of rail transit vehicles, huge in market potential, capable of achieving rapid coupling and unlocking of the through channel, capable of widening the application range of the through channel and considerable in economic benefit.

Description

Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a tunnel with a novel fast tightening mechanism, which can quickly and reliably realize the retraction of the tunnel, shorten operation time, reduce labor intensity, and improve operation efficiency. Background technique: [0002] The through passage is an internal passage for passengers to walk freely from one compartment of the vehicle to another and make passengers feel safe and comfortable. The tightening device is one of the important components of the through passage, which is used to retract, fix and release the through passage . [0003] In the existing rail vehicles, the tightening and fixing of the passageway is realized by manually pushing and pulling in place and then binding the tightening rope. The operation is cumbersome and requires the assistance of 2 or more personnel to complete it, which is time-consuming and labor-intensive. , for...

Problems solved by technology

[0003] In the existing rail vehicles, the tightening and fixing of the passageway is realized by manually pushing and pulling in place and then binding the tightening rope. The operation is cumbersome and requires the assistance of 2 or more personnel to complete it, which is time-consuming and labor-intensive. , for example: Chinese patent 201310364052.2 discloses a through-passage tightening rod assembly in the process of automobile transportation, including a positioning ring, a positioning seat, two fixing cards and a tightening rod, the positioning ring is fixed on the screw frame of the vehicle passage, and the positioning seat It is fixed on the connection frame of the vehicle through passage; the tightening rod is composed of a turning handle and two pulling rods, the two ends of the turning handle are provided with internal threads, one end of the two pulling rods is provided with a hook, and the other end is provided with external threads , the turning handle and the two pull rods are connected by threads, and the distance between the two pull rods increases or decreases through the cooperation of the internal and external threads; the two fixing cards are fixed in the middle of the screw frame of the vehicle through passage, and the two fixing cards are set up and down. And the distance between the two is greater than or equal to the overall length of the handle
