Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
With reference to Fig. 1 ~ Fig. 4, a kind of transmission line Di Nima guiding rope fixing-line device, comprise top board 1, lower platen 2 and joining shackle 3, described top board 1 is fixedly mounted on the described lower platen 2, one end of described lower platen 2 is installed described joining shackle 3, the end face middle part of described lower platen 2 is provided with second circular groove, the middle part, bottom surface of described top board 1 is provided with upper half-round slot, described upper half-round slot be positioned at described second circular groove directly over, it is big or small adaptive that the cavity size that described upper half-round slot and described lower half circle groove form and the guiding of described enlightening Nima are restricted.
The two ends of described second circular groove, upper half-round slot are equipped with the guiding chamfering.
Described top board 1 has more than two at least, and each piece top board 1 is installed on the described lower platen 2 successively.The both sides of described top board 1 have installing hole, and the both sides of described lower platen 2 have down installing hole, and bolt 4 is installed in described going up in installing hole and the following installing hole.
In the present embodiment, the Di Nima fixing-line device is according to lead, ground wire and optical cable fixing-line device principle, adopts bolt that Di Nima is fixed between two plates, produces anchor force by friction, and to reach the requirement of anchoring Di Nima, its structure is seen shown in Figure 1.Enlightening Nima fixing-line device is made up of top board 1, lower platen 2, bolt 4, joining shackle 3.This enlightening Nima card line passes through to increase pressing plate length to increase contact area between Di Nima and the fixing-line device in design process, and be designed to arc form at upper and lower pressing plate and Di Nima contact site, and the two ends of last lower platen are provided with chamfering, thereby avoid the Di Nima strop impaired.
It is shown in Figure 3 that enlightening Nima fixing-line device uses layout to see.For reducing the stressed of single fixing-line device, avoid Di Nima impaired, adopt two fixing-line device forms during use, two fixing-line devices connect by the steel wire cover, steel wire be enclosed within be connected to anchor point unload the buckle doubling, thereby make about the stressed F/2 of being controlled at of each fixing-line device.In addition, during layout, for reducing the knuckle of Di Nima between two fixing-line devices, the steel wire cover should suitably be joined the long L that is, presses L 〉=5X configuration, and X is the distance between two fixing-line devices.
The requirement of fixing-line device prefastening torque: because of in a single day enlightening Nima fixing-line device skids, will Di Nima be broken, and for this reason, need strict control screw-down torque in the use of enlightening Nima card line, general screw-down torque value draws after testing by many groups.Test requirements document: with Di Nima pretension slightly, pretightning force is controlled at about 10% of Fracture Force, then by Fig. 3 fixing-line device is installed (1); (2) adopt a certain torque value to test according to fixing-line device, fixing-line device is non-slip after guaranteeing to move required value to; (3) remove fixing-line device, Di Nima is done the rupture pull force test, require the former Fracture Force of Fracture Force 〉=95% of Di Nima.
The fixing-line device operation requires: injured after using fixing-line device for avoiding Di Nima, require every even pretension of bolt, and promptly need adopt the spanner that can set torque value to operate.And operation notes: (1) installs the middle pressing plate of each Di Nima fixing-line device earlier, and promptly pressing plate 2, see Fig. 4, and requires the even successively pretension in diagonal angle to the prescribed torque value; (2) follow the even successively pretension in all the other pressing plate diagonal angles to the prescribed torque value; (3) Di Nima that contacts with the steel wire cover is required to use the rubber tube jacket, avoid steel wire rope plug place damage Di Nima.
This Di Nima fixing-line device is present domestic initiation, φ 8(prefastening torque is that (prefastening torque is 80Nm～85Nm) at the trial for 40Nm～45Nm) and φ 18 enlightening Nima fixing-line devices, hold and put forth effort to reach 25kN and 80kN respectively, satisfy Di Nima anchoring requirement, and to the Di Nima not damaged.And φ 8 and the successful utilization of φ 18 enlightening Nima fixing-line devices in 220kV Zhoushan and the big leap stringing of continent networking work transmission line spiral shell head water channel construction operation, fully shown its superiority, for good basis is laid in the utilization of Di Nima in important transmission line stringing from now on.
Along with construction extensive, high-grade electricity power engineering, the use of enlightening Nima guiding rope will be more and more frequent also, particularly cross over increasing of stringing engineerings such as industrial crops, house, fish pond reservoir, great river, great river, navigation channel, be the special-purpose fixing-line device of Di Nima guiding rope and in transmission line stringing engineering, apply the space that provides wide.
