Abstract
The invention discloses a bridge shock absorber, which comprises a bottom bridge seat, a middle inner cavity penetrating left and right is arranged in the bottom bridge seat, a symmetrical bridge deck beam is arranged on the upper end surface of the middle inner cavity, the bridge There is an open support inner cavity inside the surface beam, and a sliding plate is installed in the middle inner cavity, and symmetrical side connecting plates are fixed on both sides of the sliding plate, and the side connecting plates are fixed on There is a built-in hydraulic push cylinder, the power connection of the upper side of the built-in hydraulic push cylinder is provided with a top backing plate, the top backing plate is supported against the bridge deck beam, and the sliding plate is provided with the A push-up support device for supporting and fixing the bridge deck girder. The device of the present invention has a simple structure and adopts the design of a push-up support device, an elastic support device and a variable-height support device, so that the equipment can stably support the bridge deck girder, And a variety of supporting devices increase the stability and firmness of the equipment support, further improving the earthquake resistance of the equipment.
Description
technical field [0001] The invention relates to the technical field of logistics sorting equipment, in particular to a bridge shock absorber. Background technique [0002] The bridge shock absorber is used to prevent the bridge from vibrating and to protect and maintain the stability of the bridge. Because the bridge itself has a natural frequency, when the vehicle above it is driven, it will bring downward pressure to the bridge itself, because the object will produce elasticity after deformation Momentum will make the bridge deck easy to vibrate. If the vibration is not stopped, it will directly cause the bridge to break, which will greatly reduce the service life of the bridge and cause the danger of bridge safety accidents. The existing bridge damping equipment installation It is inconvenient, and it is not convenient for large-scale installation. It can only be installed for individual bridge areas, which will reduce the practicability of the equipment. Effective shock...
