Abstract
A grease filling device of a stayed-cable beam end cable guiding pipe comprises a ring-shaped water drainage oil filling tie plate (1) which is provided with a middle circle on an external step disk on one end surface of a center circle, wherein an ex-circle is arranged on the outer step disk of the middle circle, the diameter (A) of the central circuit is smaller than the diameter (B) of the middle circle, the diameter (B) of the middle circle is smaller than the diameter (C) of the ex-circle, and an inner thread of a ring wall hole of a ring on the other end surface of the central hole is meshed with a bolt (2). The device is used for filling and replacing nursing grease of the end beam cable guiding pipes during the operation period of the stayed-cables, is applicable to steel box beam stayed cables, is matched with stayed-cable end beam anchors for uses, and is extremely convenient for nursing beam end cable guiding pipes of the stayed-cables.
Description
One, technical field
The utility model relates to the suspension cable protective device, especially a kind of perfusion grease device of suspension cable beam-ends cable guide pipe.
Two, background technology
Fast development along with the modern construction engineering science and technology, adopt drag-line to can be found everywhere as the Cable Structure engineering construction of supporting member, as cable stayed bridge, suspension bridge, bowstring arch bridge, what steel wire was solid and reliable in the ground tackle at suspension cable two ends and the rope is coupled as one, and give drag-line with dead load and loading transfer thereof, the importance of dragline anchorage is conspicuous.In order to make ground tackle long-term operate as normal under various environments for use, must effectively protect it.
Drag-line two ends ground tackle is individually fixed in tower end and beam-ends.The protection of dragline anchorage comprises top and bottom two parts.Mouth down on the drag-line cable guide pipe of upper end wherein presses closely connectedly between ground tackle nut and anchor plate, the drag-line cable guide pipe all is not easy into water during construction and operation, as long as carry out the protection of ground tackle.And the opening of lower end drag-line cable guide pipe up, is easy to accumulate rainwater in construction period, the also normal water inlet phenomenon that occurs during the operation.It is reported, there are the drag-line of quite a few cable stayed bridge, arch bridge and suspension bridge and suspension rod the steel wire of ground tackle even drag-line to be caused heavy corrosion because of the lower end water inlet, common processing mode is to have some sluicing grooves at anchor circle end face, but when screwing on the anchor circle, the sluicing groove can not guarantee opening down on the anchor circle, and the sluicing groove on the anchor circle is smaller, is easy to be stopped up by the foreign material in the cable guide pipe, and drainage effect is bad and cause drag-line and ground tackle cable guide pipe in to corrode easily.
Three, summary of the invention
The purpose of this utility model provides simple in structure, can discharge the ponding in the cable guide pipe easily, but also can pour in cable guide pipe and changes the maintenance grease, prevents the perfusion grease device that drag-line in the cable guide pipe and ground tackle generation are corroded.
Technical scheme that the purpose of this utility model adopts, the outer step disk of center circle one end face that comprises annular sluicing oiling backing plate has middle circle, the outer step disk of middle circle has cylindrical, its described center circle diameter A is less than middle circle diameter B, middle circle diameter B is less than outside diameter C, and center circle other end annulus ring wall hole internal thread and bolt mesh.
The utility model, the outer step disk of middle circle has the protective cover bolt hole to locate on the circumference of diameter E bolt hole.
The utility model and suspension cable beam-ends ground tackle are used, and vertically slot under anchor plate, and open screw; water inlet in the cable guide pipe is used for draining, perfusion and replacing maintenance grease, even also can be protected drag-line and ground tackle in the cable guide pipe well; have simply, make characteristics such as easy to assembly.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model sectional structure schematic diagram;
Fig. 2 is Fig. 1 left side TV structure schematic diagram;
Fig. 3 is that the utility model uses the assembling schematic diagram.
Among the figure: the diameter of 1-annular sluicing oiling backing plate 2-bolt 3-bolt hole 4-drag-line 5-cable guide pipe 6-anchor plate 7-anchor circle 8-anchor cup 9-protective cover A-center circle diameter B-middle circle diameter C-outside diameter D-annular sluicing oiling backing plate external diameter E-protective cover bolt hole location
Five, the specific embodiment
As shown in Figure 1 and Figure 2, the outer step disk of center circle one end face that comprises annular sluicing oiling backing plate 1 has middle circle, the outer step disk of middle circle has cylindrical, its described center circle diameter A is less than middle circle diameter B, middle circle diameter B is less than outside diameter C, and center circle other end annulus ring wall hole internal thread and bolt 2 mesh.The outer step disk of middle circle has the protective cover bolt hole to locate on the circumference of diameter E bolt hole 3.
Fig. 3, the utility model use the assembling situation, with the sluice centre bore centering of oiling backing plate 1 and anchor plate 6 of annular, welds in placely, and attention must sluice annular under the screw court of oiling backing plate 1; Interior centre bore to the anchor cup 8 with anchor plate 6 of center circle diameter A circle that then drag-line 4 ground tackles is penetrated cable guide pipe 5, annular sluicing oiling backing plate 1 exposes; Drag-line 4 is stretched to design Suo Li; It is in place to the anchor circle external diameter and the middle circle diameter B step of annular sluicing oiling backing plate 1 to screw in anchor circle 7 after stretch-draw finishes; And protective cover 9 is placed on the outside diameter C step of annular sluicing oiling backing plate 1, it is in place to adopt bolt to connect; Both can also can in cable guide pipe 5, pour into grease, and fill the back and screw is stopped up with screw thread by the screw draining of annular sluicing oiling backing plate 1 by the screw of annular sluicing oiling backing plate 1.Annular sluicing oiling backing plate outer diameter D.
Claims (2)
1. the perfusion grease device of a suspension cable beam-ends cable guide pipe, the outer step disk of center circle one end face that comprises annular sluicing oiling backing plate (1) has middle circle, the outer step disk of middle circle has cylindrical, it is characterized in that: described center circle diameter (A) is less than middle circle diameter (B), middle circle diameter (B) is less than outside diameter (C), and center circle other end annulus ring wall hole internal thread and bolt (2) mesh.
2. require the perfusion grease device of 1 described a kind of oblique cord beam-ends cable guide pipe according to claim, it is characterized in that: the outer step disk of middle circle has the protective cover bolt hole to locate on the circumference of diameter (E) bolt hole (3).
