The present application will be further described with reference to the following drawings and specific embodiments:
fig. 1 is a schematic structural diagram of a cable end node in an embodiment of the present application;
FIG. 2 is a schematic view of the position of the first end plate, the ear plate and the pin of FIG. 1;
wherein: 1-steel compression ring beam, 2-inhaul cable, 3-cable head, 4-first end plate, 5-second end plate, 6-lug plate, 7-connecting plate, 8-pin shaft and 9-reinforcing plate.
Detailed Description
Fig. 1 shows a specific embodiment of the cable end node for accommodating the cable length installation error, which comprises a steel compression ring beam 1, a cable 2 and a cable head 3 arranged at the end of the cable.
The key improvement of this embodiment is that there is also provided a first end plate 4, a second end plate 5, an ear plate 6 and a connecting plate 7. Wherein:
the lug plate 6 is vertically fixed on one side of the first end plate 4, and the lug plate 6 and the first end plate 4 can be respectively an integral casting piece or two independent pieces which are mutually welded and fixed.
The connecting plate 7 is vertically fixed on one side plate surface of the second end plate 5, and the connecting plate 7 and the second end plate 5 can be respectively an integral casting piece or two independent pieces which are mutually welded and fixed. And the connecting plate 7 is welded and fixed with the steel pressure ring beam 1.
The first end plate 4 and the second end plate 5 are arranged in an abutting manner, and both are provided with a plurality of (6 in the figure) through holes. And the first end plate 4 and the second end plate 5 are fastened and connected by means of bolts inserted through the through holes and nuts fitted with the bolts. The bolt is a high-strength bolt.
The pin hole has been seted up on otic placode 6, wears to establish the round pin axle 8 that is connected with cable head 3 in this pinhole, so realizes 2 tip of cable and otic placode 6 fixed, and otic placode 6 is fixed mutually with steel clamping ring roof beam 1 again, goes on and has realized the fixed connection of cable 2 with steel clamping ring roof beam 1.
During assembly, the connecting plate 7 and the second end plate 5 which are fixed together are installed on the steel compression ring beam 1, namely the connecting plate 7 and the steel compression ring beam 1 are fixed. After measuring the installation error of cable length error and steel compression ring beam structure, modify the size of otic placode 6, guarantee that the center of round pin axle 8 is located the design position, refabricate otic placode 6 and first end plate 4 of reciprocal anchorage, with high strength bolt with first end plate 4 and second end plate 5 fastening connection.
From top to bottom, because the cable 2 is not directly connected with the steel compression ring roof beam 1, but with the help of otic placode 6, first end plate 4, connecting plate 7 and second end plate 5 with the indirect transitional coupling of steel compression ring roof beam 1. When the length of the inhaul cable 2 has an error (particularly, the size is smaller than an ideal value), the error can be compensated by adjusting the size of the lug plate 6.
In this embodiment, in order to improve the connection stability, the two ear plates 6 are fixedly disposed on the first end plate 4, and the two ear plates 6 are arranged in parallel at intervals. The pin shaft 8 simultaneously penetrates through the pin holes of the two lug plates 6.
The first end plate 4 and the second end plate 5 are square plates which are easy to manufacture.
In order to enhance the connection strength between the connection plate 7 and the second end plate 5, a plurality of triangular reinforcing plates 9 are perpendicularly welded between the connection plate 7 and the second end plate 5 in the present embodiment.
It should be understood that the above-mentioned embodiments are only illustrative of the technical concepts and features of the present application, and the present application is not limited thereto.
