Technical Field

The present disclosure relates to a bidirectional vibration damping device suitable for an escalator. The present disclosure also relates to an escalator comprising a bidirectional vibration damping device as described above.

Background

In the prior art, although the strength and flexibility of the escalator truss structure meet design standards and associated code requirements, the passenger activity of a large span escalator can dynamically cause vibration or sway. Excessive vertical and lateral vibration amplitudes and accelerations caused by structural resonance can lead to poor riding comfort for passengers and can easily cause panic or safety concerns for passengers and business owners. In the prior art, designers developed a damping device to reduce lateral sway of the truss structure, but it has little help in vertical vibration. In addition, under the limit space, the vertical natural vibration frequency of the truss structure is improved by increasing the section size and the section outline size of the structure, so that the total weight of the structure is increased. Economy is also a limiting factor in applying such conventional solutions.

The lateral damper is connected between the truss of the escalator and the building.

The diagonal damper is connected between the truss of the escalator and the building.

The length direction of the diagonal damper is at an angle relative to the length direction of the lateral damper.

When the escalator generates transverse resonance and vertical resonance, the transverse damper and the oblique damper are subjected to vibration and reciprocating shear deformation in the transverse direction and the vertical direction simultaneously, so that energy is absorbed and dissipated, and the vibration response of the escalator is attenuated and controlled.

According to the above aspect of the present disclosure, the bidirectional vibration damping device further includes a truss attachment assembly and a building attachment assembly.

One end of the lateral damper is connected to the truss of the escalator through the truss connection assembly.

The other end of the lateral damper is connected to a building through the building connection assembly.

One end of the diagonal damper is connected to the truss of the escalator through the truss connection assembly.

The other end of the diagonal damper is connected to a building through the building connection assembly.

According to the above aspects of the present disclosure, one or more of the lateral dampers and one or more of the diagonal dampers are disposed along the length direction of the truss of the escalator and between both sides of the truss of the escalator and the building.

The structure according to the present disclosure is mainly composed of an escalator, a truss connection assembly, a building connection assembly, a lateral damper, and a diagonal damper. When the escalator generates transverse and vertical resonance under the excitation of human activities, the transverse damper and the oblique damper (a certain installation angle is formed between the transverse damper and the oblique damper) are subjected to vibration in two directions and reciprocating shear deformation simultaneously, so that energy is absorbed and dissipated, the vibration response of the escalator is attenuated and controlled, the riding comfort of passengers is improved, and the fear or safety worry of the passengers and business owners is avoided.

Through the design to staircase truss overall structure, can effectively reduce the cost that improves staircase natural frequency.
