Abstract
The utility model discloses a tensile rotating and loosening prevention fixing device of a stay cable. The fixing device comprises a backing plate which is connected between the tensile rod nut and the jacket of the tensile device of the stay cable. The backing plate is connected with a positioning baffle for warding off an ear plate on the staple bolt of the jacket. The rotating and loosening prevention fixing device has the characteristics of simple operation, using safety, etc., effectively protects construction equipment and personnel and improves the process and the method of the tensile construction of the stay cable. The fixing device plays a good role in preventing the loosening of the stay cable during the pulling process. The tensile construction equipment is also protected effectively to guarantee the construction safety.
Description
Technical field
The utility model belongs to the inclined guy cable stretching device, is specifically related to a kind of slanting bracing wire tensioning avoiding rotation relaxation fixing device.
Background technology
Owing to be subjected to suspension cable self structure (parallel steel wire suspension cable structure requires to have certain inherent windup-degree) and play the influence of dish (external overall of playing dish and can increase rope is reversed), self rotates lax easily in the inclined guy cable stretching process, length is long more, it is many more that the drag-line that stretching force is big more himself rotates the lax number of turns, the speed of rotation is fast more, the torsion of rotation is big more, in case rotate, suspension cable self the structure angle will reduce, to have a negative impact to suspension cable length and application life, and rotation destroys tensioning equipment easily even jeopardizes constructor's safety at a high speed.And in the inclined guy cable stretching device, do not have corresponding device thereof to prevent that the inclined guy cable stretching rotation is lax now.
Summary of the invention
The purpose of this utility model is to provide a kind of slanting bracing wire tensioning avoiding rotation relaxation fixing device, to address the above problem.
The technical solution of the utility model is: slanting bracing wire tensioning avoiding rotation relaxation fixing device, it comprises the tension rod nut that is connected the inclined guy cable stretching device and the backing plate between the jack, connect postive stop baffle on the backing plate, postive stop baffle blocks the otic placode on the jack anchor ear.
This anti-rotation lax fastening devices has characteristics such as simple to operate, safe in utilization, and construction equipment and personnel have been carried out effective protection, has improved the technology and the method for inclined guy cable stretching construction.Played the excellent prevention effect to preventing that occurring in the inclined guy cable stretching process relaxes, stretching construction equipment has also obtained effective protection, has guaranteed construction safety.
Description of drawings

Fig. 2 slanting bracing wire tensioning avoiding rotation relaxation fixing device structural representation.
The specific embodiment
As shown in Figure 1, the inclined guy cable stretching device comprises punching jack 1, and tension rod 2 passes punching jack 1, and has the tension rod nut 3,4 of punching jack 1 both sides to connect; Pass and connect reducing nut 5 on the tension rod of punching jack, reducing nut 5 connects suspension cable anchor heads 6, and suspension cable anchor head 6 is by 7 lockings of anchor head nut.Be connected between punching jack 1 and tension rod nut 3 backing plate 8 is set, connect postive stop baffle 9 on the backing plate 8, postive stop baffle 9 blocks the otic placode 10 on the jack anchor ear.
As shown in Figure 2, postive stop baffle 9 has the block 9-1, the 9-2 that are provided with at interval to constitute the otic placode groove 9-3 of the neutral gear between two blocks.Otic placode 10 is located in the otic placode groove 9-3.
The postive stop baffle vertical welding is connected on the backing plate, is the key point of device, and it passes to the suffered revolving force of backing plate on the jack outer shell, makes jack and tension rod that relative displacement not take place.
The operating principle of anti-rotation lax fastening devices is: when rope rotates, the backing plate of device is owing to be subjected to the pressure of jack and tensioning nut, between backing plate and tensioning nut, tension rod, the jack inner casing relative displacement can not take place, and can rotatablely move together along with tension rod, otic placode on the jack anchor ear can prop up the postive stop baffle of device at this moment, stop the rotation of backing plate, the so whole rotation that has prevented tension rod nut, tension rod, jack inner casing, thus the rotation that has prevented suspension cable is lax.
Claims (2)
1, a kind of slanting bracing wire tensioning avoiding rotation relaxation fixing device, it comprises the tension rod nut that is connected the inclined guy cable stretching device and the backing plate between the jack, it is characterized in that connecting on the backing plate postive stop baffle, postive stop baffle blocks the otic placode on the jack anchor ear.
2, slanting bracing wire tensioning avoiding rotation relaxation fixing device according to claim 1 is characterized in that postive stop baffle has the block that is provided with at interval to constitute the otic placode groove of the neutral gear between two blocks.
