Problems solved by technology

Due to the above-mentioned reasons, the structure may produce obvious torsional vibration. Under a certain excitation, this torsional vibration will intensify and lead to the stability of the upper part. Even if the suspended vehicle load is used, the torsional vibration of the structure will still be caused.

Embodiment Construction

[0030] like Figure 1-5 Shown in , 8: a kind of arrangement method that is used for the linear adjustment of cable rail elevated aerial rail structure and damping structure, existing empty rail structure comprises two parallel tracks 1 and the main cable that is respectively positioned at the bottom of track 1 4. The two parallel rails 1 are connected by transverse connecting rods 6, the rails 1 and the main cables 4 below them are connected by vertical struts 7, and supporting piers 8 are provided around the bottom of the empty rail structure; It is characterized in that it comprises the following steps:

[0031] Step 1: Install the tie rod cable 2;

[0032] In view of the deflection caused by the asymmetry of the main cable 4 force on both sides of the existing empty track structure, a bundle of tie rod cables 2 is installed on both sides of the empty track structure, and the tie rod cables 2 are respectively located on the structural plane of the track 1 and the main cable...

Abstract

The present invention involves a layout method for line -type adjustment and vibration reduction structure for the cable elevated air rail structure. Step 1: Install the trolley rod; install a tie rod on both sides of the air rail structure.Outside the structure plane of the main cable, the line -type adjustment is implemented through the tie rod rod; step 2: install two support rods and shock absorbers; use a supporting rod with several shock absorbers on a bouquet of a tie rod.Two support rods and shock absorbers form a vibration reduction device in vertical and horizontal dimensions, which realizes the stability of the horizontal twisted twist and the stability of the vehicle;For the transmission of the two supporting rods up and down, to increase the level of the upper structure of the air rail and overcome the deformation of the transformation, that is, the gravity rigidity;The root support rod increases the overall vertical anti -deformation capacity of the air rail structure along the vertical division.

Description

technical field [0001] The invention relates to the field of aerial rails, in particular to a method for line adjustment and vibration-damping structure arrangement of a cable rail elevated aerial rail structure. Background technique [0002] The aerial track patent is an innovative transportation system. Due to the light structure, when the moving load acts on it, it will cause lateral torsional vibration of the structure, which will affect the driving comfort and cause rollover and rollover in severe cases. Experimental research shows that this phenomenon is more obvious at low and medium speeds. The reason is that under the action of moving load, the lateral deformation of the structure caused by the structure itself and the load is amplified under the dynamic characteristics, but the lateral direction of the structural system lacks the source of stiffness to resist deformation. [0003] After the invention patents 201010254005.9 and 201210009152.9 of cable rail elevated...
