Description

Technical Field

[0001] This utility model relates to the field of relay device technology, specifically a relay device for adjusting the clamping stroke. Background Technology

[0002] The relay unit, also known as the governor cylinder or operator, is an important component of a hydro-generator set. Its main function is to amplify the hydraulic energy of the governor, converting the reciprocating movement of the governor piston into the reciprocating movement of the relay unit's main pressure distribution valve. This controls the opening and closing of the water guiding mechanism (such as guide vanes) to regulate the turbine's flow rate and thus adjust the turbine's speed.

[0003] For adjusting the clamping stroke of the relay, a large open-end wrench is usually used to adjust the position of the push-pull head of its piston rod. Due to the large size and heavy weight of the relay, the adjustment process requires the cooperation of multiple people. Moreover, the need to use a sledgehammer to strike it not only results in high labor intensity but also poses certain dangers. Therefore, a relay clamping stroke adjustment device is proposed.

[0028] By setting an adjustment component, the clamping amount of the push-pull head 2 can be adjusted, thereby improving the adjustment efficiency of the push-pull head 2. The adjustment component includes a rotating shaft 6, a sleeve 7, and a fixing frame 8. One end of the rotating shaft 6 is rotatably connected to one side of the support frame 5. The sleeve 7 is movably sleeved on the outside of the rotating shaft 6. The fixing frame 8 is fixedly connected to one end of the sleeve 7. Insertion holes are opened on both sides of the fixing frame 8. Fixing bolts 9 are movably connected inside the fixing frame 8. A limit post 10 is fixedly connected to the support frame 5. By moving the limit post 10 to the outside of the hexagonal groove 17, the relay body 1 can be completed. The piston rod is limited; a limit component is provided on the inner side of the fixed frame 8, and a drive motor 14 is installed on one side of the support frame 5. The output shaft of the drive motor 14 is fixedly connected to one end of the rotating shaft 6 extending to the outside of the support frame 5. By moving the top plate 11 to the inside of the push-pull head 2, and then moving the fixed frame 8 to the outside of the push-pull head 2, and then by passing the fixing bolt 9 through the through hole, the push-pull head 2 and the inside of the fixed frame 8 in sequence, and then fixing the fixing bolt 9 with a nut, the output shaft of the drive motor 14 drives the fixed frame 8 to rotate, thereby adjusting the clamping amount of the push-pull head 2.

[0029] By setting a limiting component, the push-pull head 2 can be limited. The limiting component includes two top plates 11, a lead screw 12, and a reduction motor 13. The two top plates 11 are slidably connected to the inner side of the fixed frame 8, the lead screw 12 is rotatably connected to the inner side of the fixed frame 8, and the two top plates 11 are movably sleeved on the outer side of the lead screw 12. The reduction motor 13 is installed on one side of the fixed frame 8, and the output shaft of the reduction motor 13 is fixedly connected to one end of the lead screw 12 extending to the outer side of the fixed frame 8. The outer side of the lead screw 12 is provided with opposite threaded sections, and the two top plates 11 are threadedly connected to the outer side of the lead screw 12. The fixing bolt 9 is fixed with a nut, and then the reduction motor 13 is started by controlling the switch group. The output shaft of the reduction motor 13 drives the lead screw 12 to rotate, and the lead screw 12 can drive the two top plates 11 to move to both sides, so that the opposite sides of the two top plates 11 respectively abut against the inner side of the push-pull head 2, thus completing the limiting of the push-pull head 2.

[0030] An electric slip ring 15 is fixedly sleeved on the outer side of the rotating shaft 6. The electric slip ring 15 is fixedly connected to one side of the support frame 5. In order to ensure that the geared motor 13 can operate normally, the electrical output end of the electric slip ring 15 is connected to the electrical input end of the geared motor 13.

By moving the fixed seat 3 to the bottom of the relay body 1, and then extending the piston rod of the hydraulic cylinder 16 to drive the support frame 5 to move upward, the limiting post 10 moves to the outside of the hexagonal groove 17, thus completing the limiting of the piston rod of the relay body 1.

[0031] Working principle or structural principle: When it is necessary to adjust the pressing stroke of the actuator body 1, the fixed seat 3 is moved to the bottom of the actuator body 1, and then the piston rod of the hydraulic cylinder 16 extends to drive the support frame 5 upward, so that the limiting post 10 moves to the outside of the hexagonal groove 17, thus completing the limiting of the piston rod of the actuator body 1. At the same time, the top plate 11 moves to the inside of the push-pull head 2, and then the fixed frame 8 moves to the outside of the push-pull head 2. Then, the fixing bolt 9 is passed through the through hole, the push-pull head 2 and the fixed frame 8 in sequence, and then the fixing bolt is secured with a nut. 9 is fixed, and then the geared motor 13 is started by controlling the switch group. The output shaft of the geared motor 13 drives the lead screw 12 to rotate. The lead screw 12 can drive the two top plates 11 to move to both sides, so that the opposite sides of the two top plates 11 abut against the inner side of the push-pull head 2, which can limit the push-pull head 2. At this time, the drive motor 14 can be started by controlling the switch group. The output shaft of the drive motor 14 drives the fixing frame 8 to rotate, thereby adjusting the clamping amount of the push-pull head 2. During the adjustment process, the sleeve 7 slides inside the rotating shaft 6, thereby ensuring the extension of the push-pull head 2.
