[0001] The utility model relates to the technical field of servomotors, in particular to a ball valve servomotor with a hydraulic locking device. Background Art

[0002] A ball valve servo is a hydraulic device that uses hydraulic pressure to transmit operating torque for mechanical operation. It mainly consists of a servo cylinder, a servo piston rod, and a crank arm hinged to the servo piston rod. The servo piston rod drives the crank arm to rotate, thereby adjusting the ball valve opening.

[0003] When a traditional ball valve servo is in the locked state, workers often need to perform complex operations or use auxiliary tools to confirm whether the locking is successful, which not only increases the complexity of the operation but also reduces work efficiency. Therefore, a ball valve servo with a hydraulic locking device is proposed. Utility Model Content

[0006] A locking limit assembly is provided on one side of the servomotor body, and a prompt assembly is provided on one side of the limit assembly;

[0007] The limiting assembly includes a support frame and a limiting plate, a connecting block is fixed on the top of the limiting plate, a locking groove is provided on one side of the connecting block, a hydraulic cylinder is fixed on one side of the support frame, a connecting frame is fixed on the end of the hydraulic cylinder push rod, and an insertion groove is provided on the bottom side of the connecting frame;

[0008] A fixing frame is fixed on one side of the connecting frame, a first sliding groove is provided inside the fixing frame, and a first sliding plate is slidably connected inside the first sliding groove.

[0009] Preferably, a locking rod is fixed to one side of the first slide, and when the locking rod is inserted into the inner side of the locking groove, the connecting frame and the limiting plate are in a connected state.

[0010] Preferably, a pull rod is fixed to a side of the first slide away from the locking rod, and an outer side of the pull rod is movable and passes through one side of the fixing frame.

[0011] Preferably, a first spring is sleeved on the outer side of the pull rod, and two sides of the first spring are respectively connected to the first sliding groove and one side of the first slide plate.

[0012] Preferably, a fixing ring is fixedly sleeved on the push rod end of the servomotor body, and one side of the support frame is fixed to one side of the servomotor body.

[0013] Preferably, the prompt component includes a slide column, a second slide plate is fixed to one side of the slide column, a plurality of third slide grooves are opened inside the limiting plate, and the inner walls of the third slide grooves are respectively provided with second slide grooves and limit blocks.

This solution only improves the hydraulic locking direction of the servo body 1, and the rest are the same as the existing products. Because it is not an improvement point, it is not described in detail. A limit assembly 2 for locking is provided on one side of the servo body 1, and a prompt assembly 3 is provided on one side of the limit assembly 2.

[0031] The limiting assembly 2 includes a support frame 21 and a limiting plate 24, a connecting block 211 is fixed to the top of the limiting plate 24, a locking groove 212 is provided on one side of the connecting block 211, a hydraulic cylinder 22 is fixed to one side of the support frame 21, a connecting frame 23 is fixed to the push rod end of the hydraulic cylinder 22, and an insertion groove 214 is provided on one side of the bottom of the connecting frame 23; a fixing frame 27 is fixed to one side of the connecting frame 23, a first sliding groove 28 is provided inside the fixing frame 27, and a first slide 210 is slidably connected to the inner side of the first sliding groove 28, and the first slide 210 drives the locking rod 213 to leave the inner side of the locking groove 212, and then pulls the limiting plate 24 downward, so that the connecting block 211 at the top of the limiting plate 24 leaves the inner side of the insertion groove 214 at the bottom of the connecting frame 23.

[0032] When the first slide 210 is in the state of being connected with the first slide 210, the first slide 210 is in the state of being connected with the first slide 210. When the first slide 210 is in the state of being connected with the first slide 210, the first slide 210 is in the state of being connected with the first slide 210. When the first slide 210 is in the state of being connected with the first slide 210, the first slide 210 is in the state of being connected with the first slide 210. When the first slide 210 is in the state of being connected with the first slide 210, the first slide 210 is in the state of being connected with the first slide 210.

[0033] The prompt component 3 includes a slide post 31, a second slide plate 36 is fixed to one side of the slide post 31, a plurality of third slide grooves 34 are opened inside the limit plate 24, and the inner walls of the third slide grooves 34 are respectively provided with second slide grooves 32 and limit blocks 37. When fitted, the ball 33 slides on one side of the fixing ring 25. When the limit plate 24 is stuck on one side of the fixing ring 25, the ball 33 is just retracted into the inner side of the third slide groove 34. The outer side of the slide post 31 is sleeved with a second spring 35. The two sides of the second spring 35 are respectively connected to the third slide groove 3 4 and one side of the second slide plate 36, the ball 33 pushes the second slide plate 36 to slide inside the third slide groove 34, and then the second slide plate 36 compresses the second spring 35 and makes one side of the slide column 31 flush with the inner wall of the second slide groove 32. The outer side of the slide column 31 is slidably connected to the inner side of the second slide groove 32. The inner side of the third slide groove 34 is provided with a ball 33 located on one side of the second slide plate 36.

At the same time, the first slide 210 compresses the first spring 29, and then the first slide 210 drives the locking rod 213 to leave the inner side of the locking groove 212, and then pulls the limit plate 24 downward so that the connecting block 211 at the top of the limit plate 24 leaves the inner side of the insertion groove 214 at the bottom of the connecting frame 23. At this time, the damaged limit plate 24 can be removed, and a new limit plate 24 can be taken out, and the connecting block 211 is inserted into the inner side of the insertion groove 214, so that the locking rod 213 is inserted into the inner side of the locking groove 212. At this time, the replacement of the limit plate 24 can be completed.

[0037] In summary, when the slide column 31 is flush with the second slide groove 32, the worker can directly visually confirm this state, thereby knowing that the push rod end of the relay body 1 has been locked by the hydraulic cylinder 22, and when the limit plate 24 is attached to one side of the fixing ring 25, the ball 33 will retract into the inner side of the third slide groove 34 and push the second slide plate 36 to slide, thereby compressing the second spring 35, which not only realizes the locking function, but also increases the locking stability through the compression of the second spring 35, preventing accidental unlocking due to external force or vibration, simplifying the confirmation process of the locking state, and improving the intuitiveness and convenience of operation.

[0038] The damaged limit plate 24 can be easily removed by controlling the push rod end of the hydraulic cylinder 22 to retract, pulling the pull rod 26, sliding the first slide 210 and compressing the first spring 29, unlocking the locking rod 213, and removing the connecting block 211. Compared with the traditional replacement method, the complexity and time cost of the operation are reduced, and the replacement of the limit plate 24 becomes easier, thereby enhancing the maintainability of the entire equipment. When the limit plate 24 is damaged, workers can quickly replace it to ensure the normal operation of the equipment.
