[0002] Bolt fastener refers to the abbreviation of bolt hydraulic tensioner, hydraulic tensioner, which uses the hydraulic source provided by the hydraulic booster pump (ultra-high pressure hydraulic pump) to determine the tensile force according to the tensile strength, yield coefficient and elongation of the material, and uses the tensile force generated by the ultra-high pressure oil pump to make the bolt to which the force is applied be elongated in its elastic deformation zone, and the bolt diameter is slightly deformed, thereby making the nut easy to loosen. In addition, it can also be used as a device for applying axial force to the hydraulic interference connection for top pressure installation. It is currently mainly used in petrochemical, nuclear power, wind power, hydropower, thermal power, shipbuilding, railways, aerospace, mining, heavy machinery and other fields.

[0022] Furthermore, the connection structure includes a connection block 37 , each of which is located between two fixed blocks 36 . The two connection blocks 37 are rotatably mounted with a connection plate 38 via a bearing, and the top ends of the two connection plates 38 are fixedly connected to the push disc 13 .

[0023] In this technical solution, the connection structure can cooperate with the push-up disc 13 to rotate through the rotational cooperation between the connection block 37 and the connection plate 38 .

[0024] Furthermore, fixing columns 11 are fixedly installed on both sides of the bolt fastener 1, and a support block 22 is fixedly installed on one side of one of the fixing columns 11, a worm 23 is spirally installed at the bottom of the support block 22, a pressure spring 25 is fixedly installed at the bottom of the worm 23, and a bracket 2 is fixedly installed at the bottom of the pressure spring 25.

[0025] In this technical solution, the elastic force of the worm 23 and the pressure spring 25 can play a certain auxiliary effect on the resetting of the bolt fastener 1.

[0026] Furthermore, a second driving motor 21 is installed at one side of the bracket 2 , and a driving end of the second driving motor 21 rotates through the bracket 2 to fix a worm gear 24 , and the worm gear 24 is meshed with the worm 23 .

[0027] In this technical solution, the second drive motor 21 drives the worm 23 to cooperate with the bolt fastener 1. When the second drive motor 21 is started, the bolt fastener 1 can be well reset.

[0028] Furthermore, elastic telescopic rods 39 are fixedly installed on both sides of the rotating plate 32 , and the other ends of the two elastic telescopic rods 39 are fixedly connected to the pushing disc 13 .
