Embodiment Construction

[0019] Embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0020] combine figure 1 and figure 2 As shown, the suspension train braking device includes a moving unit, a braking unit and a reset unit.

[0021] The mobile unit includes a brake trolley 30 . The upper end of the brake trolley 30 is suspended on the track beam 1, and can move back and forth along the length direction of the track beam 1; When the suspension train cannot stop, the column 3 will bump into the buffer device 301 of the brake trolley 30, and drive the brake trolley 30 to move together, wherein the center of the bumping top column 3 is aligned with the center of the buffer device 301 to ensure that the bumping of the top column 3 accurately impact on the buffer device 301. The buffer device 301 can reduce the impact force during the collision between the suspended train 2 and the brake trolley 30 .

[0022] Preferably, the upper end of the brake ...

Abstract

The invention relates to the field of suspension train braking, in particular to a suspension train band brake type braking device. In order to solve the problem that a braking system of the suspension train fails to stop, the present invention proposes a suspension train band brake type braking device, which comprises a moving unit and a braking unit. The moving unit includes a braking trolley, and a brake trolley can reciprocate in the length direction of a track beam. The braking unit includes braking hoists, one-way clutches, drive shafts, braking steel wire ropes and band brake devices; the brake hoists are connected to the drive shafts through the one-way clutches; the braking steel wire ropes are connected to the brake trolley and the brake hoists; each band brake device comprises brake shoes, a brake disc, a pre-tightening nut and a pre-tightening bolt, wherein the brake disc is fixed on the drive shaft through a connecting key, the brake shoes are fixed on an outer surface ofthe brake disc through the pre-tightening nut and the pre-tightening bolt. The device can allow the suspension train to quickly and smoothly stop when the suspended train fails to stop.

Description

technical field [0001] The invention belongs to the field of suspension train braking, in particular to a suspension train brake-type braking device. Background technique [0002] The suspended train system includes track beams and suspended trains. The track beam is a hollow cuboid structure and has a through opening on its bottom surface, and the track beam is supported in the air by a steel column or a cement column. The body of the suspended train is connected to the wheels through the suspension mechanism, and the wheels are connected to the track beam through the opening part of the track beam, thereby completing the connection between the suspended train and the track beam, and realizing the reciprocating movement of the suspended train along the length direction of the track beam. [0003] When the suspended train is running in the air, if its own braking system breaks down and cannot be stopped, the suspended train will run to the end of the track beam, which may c...
