Description
Technical field
The utility model belongs to cable crane technical field of construction, and in particular to a kind of suspension bridge of head-rope series-mode frame
Cable crane load bearing system.
Background technology
With the development of construction technology, application of the cable crane in suspension bridge construction is more and more, the across footpath of cable crane
Across footpath with suspension bridge is increasing.The anchorage system and Sarasota system that galvanized wire for suspension bridge is hung are existing suspension bridge body junction
Structure, force request can be met, and the head-rope of cable crane is cable crane unique load-carrying members in the air, cable crane sport car will
Load-carrying carrys out fallback on head-rope and moved, and the load for playing hanging object is assigned on head-rope by sport car.Getting over based on cable crane across footpath
Greatly, the higher situation of requirement to Lifting Capacity, it is necessary to which the radical of the diameter and increase head-rope that increase head-rope is held with reaching
The force request restricted again.Erection and regulation of the structure type of each head-rope to load-bearing are most important.
And head-rope, when using parallel-connection structure, every head-rope uses independent steel wire rope, is independent of each other between head-rope,
It can set up by root and be anchored by root, and single wire rope can be replaced, security is higher.But if every rope
Regulation is highly inconsistent, it will and cause every head-rope discontinuity, situations such as sport car deflection, local pressure is excessive occur,
Threat will be formed to construction safety, while influences construction quality.When head-rope uses cascaded structure, rope can be considered as elongated
Structure, particularly on large-span suspension bridge, if rope is long, drawing will be very difficult, and if one of point fracture,
The overall phenomenon that all will appear from collapse, security are relatively low.
Utility model content
The purpose of this utility model is to overcome prior art head-rope to connect, and not only drawing is difficult, and if wherein one
Individual point fracture, entirety all will appear from the phenomenon of collapse, and security is relatively low, and be easily caused every rope regulation height using parallel-connection structure
Spend inconsistent, it will make every head-rope discontinuity, situations such as sport car deflection, local pressure is excessive problem occur.
Therefore, the utility model, which provides a kind of galvanized wire for suspension bridge of head-rope series-mode frame, hangs load bearing system, suspension cable
There is anchor system bridge two sides, and multiple tower top deflecting rollers, the galvanized wire for suspension bridge of head-rope series-mode frame are equipped with the Sarasota of two sides
Hanging load bearing system includes the head-rope of more head and the tail connections；
The anchor system includes the anchor plate band that polylith be arranged in parallel, two pieces of anchors of anchor system both sides described in two sides
Gu being equipped with grappling gyroscope wheel on steel plate strip, remaining anchor plate band is at interval of a setting grappling gyroscope wheel, first head-rope
Both ends respectively around corresponding to tower top deflecting roller on corresponding grappling gyroscope wheel and two sides Sarasota on the anchor system of suspension bridge two sides,
The fag end of remaining head-rope is sequentially connected the tower top deflecting roller of two sides Sarasota after being connected with the tail of rope of previous head-rope, afterwards should
The tail of rope of head-rope bypasses corresponding grappling gyroscope wheel, and more head-ropes connect according to this in order, the tail of rope of last root head-rope around
It is connected after crossing corresponding grappling gyroscope wheel with the fag end of first head-rope.
Clamping plate is provided between the tower top deflecting roller of the anchor system and Sarasota, the clamping plate is vertical with head-rope, and with it is every
Root head-rope connects.
Fixed between the head-rope by card of restricting.
The anchor plate band is provided with pin shaft hole, and the grappling gyroscope wheel passes through the bearing pin and anchor plate in pin shaft hole
Band connection.
The head-rope is even number root.
The beneficial effects of the utility model are：
The utility model load bearing ropes of cable crane uses serial arrangement, by root haulage cable during construction, anchoring temporarily,
After all head-rope drawings, series connection is connected into using rope card, overcomes drawing difficult, and avoid because of one of point
Fracture, the overall phenomenon that all will appear from collapse, improves security.By installing clamping plate so that every head-rope independent stressed.
Simultaneously avoid using parallel-connection structure be easily caused every rope regulation it is highly inconsistent, make the every stress of head-rope 1 not
Uniformly, there is situations such as sport car deflection, local pressure is excessive problem.
It is described in further details below in conjunction with accompanying drawing.
