Abstract
The invention discloses a main rope saddle for a bridge, comprising a saddle head and a saddle assembly at the bottom of the saddle head, wherein the saddle assembly comprises an upper support plate, a sliding plate and a lower support plate in the order from top downwards; the upper support plate is fixedly connected to the bottom of the saddle head; and the sliding plate is fixedly connected to the lower support plate and slidingly connected with the upper support plate. The main rope saddle for the bridge has the following advantage that uneven load of the bridge is accommodated through relative movement between the upper support plate and the lower support plate, so that the load of the bridge tower is reduced and requirements for the main tower are reduced.
Description
Technical field
The present invention relates to the bridge technology field, particularly a kind of main rope saddle that is used for bridge.
Background technology
The main rope saddle of bridge is arranged on the bridge tower top; Carry main push-towing rope in the groove in the middle of the main rope saddle; For general bridge, do not slide between main push-towing rope and the main rope saddle, do not slide between main rope saddle and the king-tower yet; Rely on the longitudinal strain of king-tower own to realize displacement, thereby come balance bridge tower both sides unbalanced loading.The structure of king-tower has two kinds: a kind of is the king-tower of steel work, and the toughness that its steel itself are good can satisfy instructions for use, but cost is very high; Another kind is the king-tower of steel concrete, though cost is more much lower than head tower, concrete anti-bending strength is relatively poor, and the amount of deflection that can bear is limited, therefore can not satisfy instructions for use.
Summary of the invention
Goal of the invention of the present invention is: the problem to above-mentioned existence, a kind of main rope saddle that is used for bridge is provided, and can adapt to the uneven load of bridge through self component movement, thereby reduce the load of bridge tower.
The technical scheme that the present invention adopts is such: a kind of main rope saddle that is used for bridge; The saddle assembly that comprises saddlebow and bottom thereof; Said saddle assembly is followed successively by upper bracket plate, slide plate and lower support plate from top to bottom; Said upper bracket plate and saddlebow bottom is fixedly connected, said slide plate be fixedly connected on the lower support plate and and the upper bracket plate between be slidingly connected.
As optimal way, said lower support plate is provided with baffle plate in the slide plate both sides, and the lower support plate two ends are provided with the limiting and protecting device of control sledge displacement amount.Being provided with of baffle plate can guarantee that upper bracket plate and saddlebow can only slide in the direction along bridge, and the setting of limiting and protecting device can be controlled the displacement of slide plate.
As optimal way, said limiting and protecting device is a limited block.Realize offset qualification with a limited block, simple in structure, convenient and practical.
As optimal way, said slide plate is that wear-resisting solid self lubricant material is processed.Adopt solid self lubricant material can make the contact surface of slide plate and upper bracket plate in the process that produces relative motion, form solid lubricant film, thereby reduce friction wearing and tearing.
In sum,, the invention has the beneficial effects as follows: can adapt to the uneven load of bridge through the relative motion between upper bracket plate and the lower support plate, thereby reduce the bridge tower load, also reduce requirement king-tower owing to adopted technique scheme.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Mark among the figure: 1 is saddlebow, and 2 is the upper bracket plate, and 3 is slide plate, and 4 is lower support plate, and 5 is baffle plate, and 6 is limiting and protecting device.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done detailed explanation.
Embodiment: as shown in Figure 1; A kind of main rope saddle that is used for bridge; The saddle assembly that comprises saddlebow 1 and bottom thereof; Said saddle assembly is followed successively by upper bracket plate 2, slide plate 3 and lower support plate 4 from top to bottom, and said upper bracket plate 2 is fixedly connected with saddlebow 1 bottom, said slide plate 3 be fixedly connected on the lower support plate 4 and and upper bracket plate 2 between be slidingly connected.
Said lower support plate 4 is provided with baffle plate 5 in slide plate 3 both sides, and lower support plate 4 two ends are provided with the limiting and protecting device 6 of control slide plate 3 displacements.
Said limiting and protecting device 6 is a limited block.
Said slide plate 3 is processed for wear-resisting solid self lubricant material.
In use, said lower support plate 4 is fixed on the bridge tower top.Under the situation of saddlebow 1 both sides cable unbalance stress, upper bracket plate 2 and saddlebow 1 can be under the effects of cable pulling force, through slide plate along along bridge to slip, thereby reduce the stress difference of saddlebow 1 both sides cable, the deflection that alleviates bridge tower.
Owing to adopted this invention, bridge can use the steel concrete bridge tower to replace the steel work bridge tower, thereby greatly reduced construction costs.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
