Description
Technical field
The utility model relates to pontoon bridge technical fields, more specifically, it relates to a kind of suspension cross a river pontoon bridge.
Background technique
Pontoon bridge refers to and replaces bridge pier with ship or buoyancy tank, the bridge kept afloat.Pontoon bridge can be used for people's row, highway, railway.Its
It constructs and uncomplicated, frame, which is torn open, also to be facilitated, but maintenance cost is high.
In the prior art, deep water spanning river construction channel pontoon bridge major anchorage on bank ridge or throw in upstream riverbed
On anchorage, anchor point is the fixed following water-level lifting that is unable to, and in flood season work progress, if water level is risen sharply, ground ridge is possible to
It is inundated with flood, hangs over the anchor line between korneforos on anchorage and also easily tangle drift, after the hawser of fixed pontoon bridge is inundated with flood
It will stop to let out under drift, pontoon bridge may be destroyed by rush of water, and safety coefficient is lower.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of suspension cross a river pontoon bridge,
Solve the problems, such as that existing pontoon bridge can not adapt to water level change dramatically.
To achieve the above object, the utility model provides following technical solution:
A kind of suspension cross a river pontoon bridge including pontoon bridge bridge floor and is fixed on the bridge bearing platforms of river two sides, further includes floating
Cylinder, main push-towing rope rope, auxiliary cable and the elevating mechanism for adjusting pontoon bridge bridge floor upper and lower position；
Described auxiliary cable one end is connect with the floating drum, and the other end is connect by the main push-towing rope rope with the elevating mechanism,
The floating drum is fixed on pontoon bridge bridge floor bottom；
It is fixed with column on the bridge bearing platform, slideway, height of the slideway along the column are provided on the column
Direction setting is spent, the elevating mechanism is slided up and down along the slideway.
Through the above technical solutions, if water level is risen sharply, can be lifted up by elevating mechanism in flood season work progress
Main push-towing rope rope, since floating drum is connect by auxiliary cable with main push-towing rope rope, when main push-towing rope rope is lifted upwards, floating drum and pontoon bridge bridge floor are by one
It rises and is lifted up.Likewise, if water level sharply declines, can by controlling elevating mechanism so that floating drum and pontoon bridge bridge floor it is whole to
Lower movement.Solving traditional pontoon bridge anchor line cannot go up and down, and flood season anchor line easily tangles drift, can not adapt to flood season level and sharply become
The problem of change improves safety coefficient of the pontoon bridge in flood season construction.
Further preferably are as follows: the elevating mechanism includes actuator, pulley, link block and cable saddle；
The link block is fixed on the cable saddle, and the pulley is mounted on link block and rotates setting with it, described
Link block slides up and down cooperation in the slideway and with it, and the pulley and slideway sliding are arranged；
Main push-towing rope rope lower end is connect with the auxiliary cable, and upper end is connect with the cable saddle, and the actuator is arranged in institute
It states at the top of column and for driving the cable saddle oscilaltion.
Through the above technical solutions, in flood season work progress, if water level is risen sharply, rope can be lifted up by actuator
Saddle, under being slidably matched of pulley and slideway, cable saddle is moved up, since floating drum is connected by main push-towing rope rope and auxiliary cable and cable saddle
It connects, therefore when cable saddle is lifted upwards, floating drum and pontoon bridge bridge floor will be lifted up with cable saddle.Likewise, if water level sharply under
Drop, can be by controlling actuator, so that cable saddle, floating drum and pontoon bridge bridge floor integrally move down.The change dramatically of water level is adapted to,
Securely and reliably.
Further preferably are as follows: the cable saddle is circular and is set in column surrounding outer surface in anchor ear shape.
Through the above technical solutions, cable saddle connect more close with column, enables the oscilaltion that cable saddle is stable, reduce
It shakes.
Further preferably are as follows: the actuator is chain block, and the chain block is hung at the top of the column and lower end
It is connect with the cable saddle.
Through the above technical solutions, it is safe and reliable, it is durable, have for outdoor and non-transformer operating environment stronger
Superiority.
Further preferably are as follows: column surrounding outer surface offers multiple slideways, and multiple slideways are to be uniformly arranged,
Multiple pulleys are installed, multiple pulleys and the multiple slipway location correspond on the cable saddle.
Through the above technical solutions, enabling cable saddle is stable to slide up and down, reduces and shake.
Further preferably are as follows: the cable saddle outer surface offers the rope slot along cable saddle circumference setting, the main push-towing rope rope
It is anchored in the rope slot.
Through the above technical solutions, convenient for placing main push-towing rope rope, good fixing effect.
Further preferably are as follows: the column is made of steel pipe, and the column lower end is anchored at the bridge bearing platform top.
Through the above technical solutions, column is enabled to be stably fixed to above bridge bearing platform, fixed effect is preferable.
In conclusion the utility model has the following beneficial effects: in flood season work progress, it, can if water level is risen sharply
It is lifted up cable saddle by chain block, under being slidably matched of pulley and slideway, cable saddle is moved up, since floating drum passes through master
Hawser and auxiliary cable are connect with cable saddle, therefore when cable saddle is lifted upwards, floating drum and pontoon bridge bridge floor will be lifted up with cable saddle.
Likewise, if water level sharply declines, it can be by controlling chain block, so that cable saddle, floating drum and pontoon bridge bridge floor integrally move down.
Solving traditional pontoon bridge anchor line cannot go up and down, and flood season anchor line easily tangles drift, can not adapt to flood season level difficulty jumpy
Topic improves safety coefficient of the pontoon bridge in flood season construction.
