Description

Technical Field

[0001] This utility model relates to the field of rail transit door systems, and in particular to an emergency evacuation ramp damping device. Background Technology

[0002] In existing rail transit emergency evacuation systems, ramps are unfolded and retracted by folding in order to save space. Furthermore, the split ramps are divided into two parts: a flap and a ramp frame, thus leaving room for the train's window view. During the unfolding process, the ramp flap needs to be released quickly into place. The flap will fall freely and hit the ramp frame, which will generate a strong impact and noise, and will also affect the structure and lifespan of the ramp.

[0003] Therefore, it is necessary to develop targeted damping devices for emergency evacuation ramps to overcome the above problems. Utility Model Content

[0008] The ramp is equipped with an inspection port, which is covered with a dust cover.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , 23. The emergency evacuation ramp damping device of this utility model includes a hydraulic damper 1, a damping rod assembly 2, a torsion spring stop 3, a torsion spring 4, a dust cover 5, a stop block 6, a cylindrical pin 7, and a retaining ring 8; the damping rod assembly 2 and the torsion spring stop 3 are installed on the hydraulic damper 1, and the torsion spring 4 is sleeved on the torsion spring stop 3. The damping rod assembly 2 is reset by two pins on the torsion spring stop 3 and the cylindrical pin 7; the hydraulic damper 1 is installed on the side of the ramp, and the damping rod assembly 2 connected to it is fixed by the retaining ring 8; the damping rod assembly 2 is connected to the stop block 6.

[0024] The ramp of this utility model is an emergency evacuation ramp. The emergency evacuation ramp is located within the rail transit door system. An inspection port is provided on the ramp, and a dust cover 5 is installed on the inspection port to prevent dust and oil from entering. The damping rod assembly 2 includes a damping rod 9, a damping shaft 10, a pin 11, and washers 12. The pin 11, damping rod 9, and damping shaft 10 are connected sequentially. Several washers 12 are provided between the damping rod 9 and the damping shaft 10; the number of washers 12 is variable and can be increased or decreased as needed to adjust the height of the pin.

[0025] When the ramp flap falls freely, the impact block 6 on the flap contacts the damping rod assembly 2 and drives it to rotate. Under the damping action of the hydraulic damper 1, the flap falls slowly, greatly reducing the impact on the ramp frame and reducing noise. At this time, the torsion spring 4 accumulates elastic potential energy during the rotation of the damping rod assembly 2, which is used to reset the ramp during the recovery process.

[0026] like Figure 4 After the ramp is recovered, the impact block 6 no longer presses against the damping rod assembly 2. Under the reset action of the torsion spring 4, the damping rod assembly 2 tilts up and rises above the ramp plane. At this time, the protrusion on the dust cover 5 plays a limiting role on the damping rod assembly 2.

[0027] like Figure 5 , 6 7, 8. When the ramp is in the recovery state, the damping rod protrudes from the ramp under the action of the torsion spring; when the ramp is in the release state, the damping rod acts as a buffer for the ramp flap.
