Specific embodiment
First embodiment of the present utility model is illustrated with reference to accompanying drawing 2 and accompanying drawing 3.
Hydraulic traction system mainly includes first hydraulic cylinder 7, second hydraulic cylinder 8, the 3rd hydraulic cylinder 9 and the 4th hydraulic cylinder
10, first hydraulic cylinder 7 and second hydraulic cylinder 8 are connected by the first loop 13 and second servo loop 14 with the second fuel tank 12, and the 3rd
The hydraulic cylinder 10 of hydraulic cylinder 9 and the 4th is connected by the loop 16 of tertiary circuit 15 and the 4th with the second fuel tank 12；Hydraulic cylinder passes through spiral shell
Bolt is fixed on locating flange 19.
Further, hydraulic cylinder is uniformly arranged on locating flange lower surface.
Meanwhile, fuel tank oil reserve is less than hydraulic cylinder inside oil reserve.
Hydraulic cylinder body is realized to two grades of pullings of tower body by flexible hydraulic system, when steel tower is received in a direction
During power, the pull bar opposite with Impact direction will automatic tension, the inclination of reduction tower body under the interaction of hydraulic cylinder.
Its structure is divided into vacuum cavity 20 and the two parts of hydraulic chamber 21, and vacuum cavity is the space of closing, hydraulic chamber
It is connected with fuel tank by loop, the end of piston rod 22 of hydraulic cylinder is articulated joint 23, and articulated joint is fork-shaped, inside is installed and turned
Axle, is socketed branch sleeve 24 in rotating shaft, branch sleeve connects the first pull bar 3, the second pull bar 4, the 3rd pull bar 5 and four-pull-rod 6；
Pull bar is steel wire rope, and pull bar end is connected with two grades of towers 1.
Further, sealing ring is installed on hydraulic cylinder piston.
Also, hydraulic cylinder piston rod is provided with sealing ring with cylinder body contact portion.
Second embodiment of the present utility model is illustrated with reference to accompanying drawing 1 and accompanying drawing 2.
Frame foundation mainly includes locating flange 19, and locating flange is annular shape, by the first support 17 and the second support
18 are fixed on first stage tower 2.
Further, locating flange internal diameter is more than first stage tower tower body caliber.
The operation principle of the system is as follows：
As a example by by horizontal wind-force, when tower body for example bears the blowing force of north wind in a direction, tower body stress has southwards
The inclined trend in side, is now in southern pull bar and is squeezed power and drives the hydraulic cylinder of hydraulic cylinder 7 to bounce back, liquid in hydraulic cylinder 7
Hydraulic oil in pressure cavity is squeezed and causes internal pressure to increase so that hydraulic oil is flowed into the second fuel tank by the first loop 13
In 12, and then it is flowed into the hydraulic chamber of the 4th hydraulic cylinder 10 so that the increase of oil pressure pressure in the 4th hydraulic cylinder, promotes the
Moved after four hydraulic cylinder piston rods so that the pulling force of four-pull-rod 6 strengthens, reduce the deformation of tower body.
