Description
Technical field
It goes on board trestle the utility model is related to position compensation extension type.
Background technology
Walk bridges or trestle are mainly used to conveying personnel or cargo, and in land, the construction of , Walk bridges is relatively easy, but use exists
Marine builds with regard to relative difficult for conveying personnel and goods and materials Walk bridges between two ships, because, between ship and ship
It mutually moves, is generally built on a ship because of Ci , Walk bridges, if necessary to use, by overlapped mode in two ships
Between She Zhi Walk bridges.And during overlap joint, to realize better overlap joint, it is necessary to the phase between Kao Lv Walk bridges and another ship
To position, Walk bridges and foul otherwise can be made into because of the floating of ship；After the completion of overlap joint, also need consider two ships between
Relative position, allow Walk bridges to be in the state that passively compensates according to the relative position of two ships, in this way, just can guarantee normally makes
With；In addition, be in an emergency Xia , Walk bridges and another ship want to realize ejection escape, to ensure security performance.
A kind of fore-and-aft gangway device, including base are disclosed in the patent document that Chinese Patent Application No. is 201510045917.8
Seat and the revolving platform above the pedestal, the revolving platform are connected by swing mechanism with the pedestal, institute
It states and is provided with driver's cabin on revolving platform, the revolving platform is connected with fore-and-aft gangway, and the both sides of the fore-and-aft gangway have safety barrier,
The suspension end of the fore-and-aft gangway is provided with docking facilities.The present invention is compared to the prior art, and reasonable structural arrangement, operation are flat
Surely, conveying people between ship and ocean platform can be realized under complicated, adverse circumstances.Shang Shu Walk Biodge devices, although can be real
Personnel between spot oceangoing ship and Material Transportation, but Da Jie Walk Biodge devices and Da Jie Walk Biodge device Hou , Walk Biodge devices cannot root
The problems such as carrying out corresponding change in location according to the change in location between ship, be susceptible to accident, and in emergency circumstances , Walk
Bridge can not carry out ejection escape.
For existing fore-and-aft gangway or trestle, channel is usually cantilever design during overlap joint, if the weight in channel is too
Weight, then can increase the burden of dynamical system, if channel weight is too light, it is possible to can influence the intensity in channel.In addition, channel is taken
After connecing, in order to preferably realize that servo-actuated compensation, existing structure are usually relatively complex, if it is simple structure, compensating not
Accurately.
Invention content
The purpose of this utility model is to provide a kind of position compensation extension type and goes on board trestle, utilizes the knot of the utility model
Structure is avoided that aluminum alloy anode corrodes, due to the effect of bulb, can give certain swing cushion space, only needs to examine in this way
Consider revolution, flexible and compensation of luff simplifies compensation without the concern for other swing angles other than change angle
Design.
In order to achieve the above objectives, a kind of position compensation extension type is gone on board trestle, including pedestal, revolving platform, flexible stack
Bridge and landing gear；Revolving platform is mounted on pedestal；Flexible trestle includes principal arm and telescopic arm, and one end of principal arm is articulated in back
Turn on platform, telescopic arm sliding is located on principal arm；Principal arm is aluminum alloy frame, and telescopic arm is aluminum alloy frame；In principal arm
