Abstract
The utility model discloses a main cable saddle used for bridge. The main cable saddle used for bridge comprises a saddle-bow and saddle components at the bottom of the saddle-bow. An upper support plate, a sliding plate and a lower support plate are sequentially from top to bottom placed on the saddle components. The upper support plate is fixedly connected with the bottom of the saddle-bow. The sliding plate is fixedly connected on the lower support plate and connected with the upper support plate in slide mode. The main cable saddle used for the bridge has the advantages of adapting the uneven load of the bridge through relative movement between the upper support plate and the lower support plate, thereby reducing the load of a bridge tower and the requirement for the main tower.
Description
Technical field
The utility model relates to the bridge technology field, particularly a kind of main rope saddle 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 the unbalanced load in balance bridge tower both sides.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, although 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.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of main rope saddle for bridge, can adapt to by self component movement the uneven load of bridge, thereby reduce the load of bridge tower.
The technical solution adopted in the utility model is such: a kind of main rope saddle for bridge, the saddle assembly that comprises saddlebow and bottom thereof, described saddle assembly is followed successively by upper bracket plate, slide plate and lower support plate from top to bottom, described upper bracket plate and saddlebow bottom is fixedly connected with, described slide plate be fixedly connected on the lower support plate and and the upper bracket plate between be slidingly connected.
As optimal way, described 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.The arranging 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, described limiting and protecting device is a limited block.Realize offset qualification with a limited block, simple in structure, convenient and practical.
As optimal way, described slide plate is that wear-resisting solid self lubricant material is made.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, owing to adopted technique scheme, the beneficial effects of the utility model are: can adapt to by the relative motion between upper bracket plate and the lower support plate uneven load of bridge, thereby reduce the bridge tower load, also reduce the requirement to king-tower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
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 utility model is described in detail.
Embodiment: as shown in Figure 1, a kind of main rope saddle for bridge, the saddle assembly that comprises saddlebow 1 and bottom thereof, described saddle assembly is followed successively by upper bracket plate 2, slide plate 3 and lower support plate 4 from top to bottom, described upper bracket plate 2 is fixedly connected with saddlebow 1 bottom, described slide plate 3 be fixedly connected on the lower support plate 4 and and upper bracket plate 2 between be slidingly connected.
Described 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.
Described limiting and protecting device 6 is a limited block.
Described slide plate 3 is made for wear-resisting solid self lubricant material.
In use, described lower support plate 4 is fixed on the bridge tower top.In 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, by 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 utility model, bridge can replace the steel work bridge tower with the steel concrete bridge tower, thereby has greatly reduced construction costs.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
