[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 The converter flue gas purification hydraulic servo system provided by this utility model is a highly integrated hydraulic valve block, including: an integrated hydraulic valve block body 1, and a quick connector 2 installed on the outer wall of one side of the integrated hydraulic valve block body 1. The outer wall of the quick connector 2 is provided with an external thread 3, and an internal threaded pipe 4 is screwed to the outside of the quick connector 2. A thrust assembly 5 is rotatably installed on the outer wall of the internal threaded pipe 4, and a plurality of equally spaced mounting frames 6 are installed at one end of the quick connector 2. An elastic assembly 7 is installed on the inner wall of the mounting frame 6, and a clamping assembly 8 is sleeved on the bottom end of the elastic assembly 7. Guide rods 9 are installed on both sides of the outer wall of the quick connector 2, and the thrust assembly 5 and the two guide rods 9 form a sliding fit.

[0015] It should be noted here that the integrated hydraulic valve block body 1 is prior art in this application document, and its structure and working principle will not be described in detail here; Connection and expansion mechanism: A quick connector 2 is installed on the outer wall of one side of the integrated hydraulic valve block body 1. With the help of the structural characteristics of the quick connector 2, it is possible to quickly connect to external temporary pipelines, test equipment or other hydraulic accessories, providing a convenient interface for the commissioning, daily maintenance and functional expansion (such as adding monitoring branches) of the converter flue gas purification hydraulic servo system.

[0016] Clamping drive start: After the quick connector 2 completes the connection of the external pipeline, the external thread 3 on the outer wall of the quick connector 2 is screwed into the internal threaded pipe 4. The internal threaded pipe 4 is rotated, and the thrust assembly 5 sleeved on the outer wall of the internal threaded pipe 4 is driven to move axially through the thread transmission.

[0017] Guiding and stability control: The guide rods 9 installed on both sides of the outer wall of the quick connector 2 form a sliding fit with the thrust assembly 5. During the movement of the thrust assembly 5, the guide rods 9 limit the radial displacement of the thrust assembly 5, ensuring that it always moves stably in the preset direction and avoiding failure of subsequent clamping actions due to displacement.

[0018] Clamping and Reset Cycle: When the thrust assembly 5 moves, it generates a thrust on the clamping assembly 8 installed in the mounting frame 6, causing multiple clamping assemblies 8 to move synchronously towards the external pipeline of the quick connector 2, thereby clamping and fixing the pipeline and preventing it from loosening or falling off due to vibration, pressure fluctuations, or other factors during system operation. During the clamping process, the movement of the clamping assembly 8 stretches the elastic assembly 7 installed on the inner wall of the mounting frame 6, allowing it to store elastic potential energy. When it is necessary to release the pipeline, the internal threaded pipe 4 is rotated in the opposite direction, the thrust assembly 5 releases the thrust on the clamping assembly 8, the elastic assembly 7 releases its elastic potential energy, and the clamping assembly 8 is reset, releasing the clamping of the pipeline.

[0019] In a preferred embodiment, the thrust assembly 5 includes a collar 501, a plurality of equidistant fixed plates 502 mounted on the outer wall of the collar 501, a pressure roller 503 mounted on one end of the fixed plate 502, and guide plates 504 mounted on the outer walls of both sides of the collar 501.

[0020] It should be noted here that: the collar 501 is fitted onto the outer wall of the internally threaded tube 4, forming a rotational fit with the internally threaded tube 4, ensuring that the collar 501 can move axially when the internally threaded tube 4 rotates, while the collar 501 itself does not rotate with the internally threaded tube 4; multiple equidistantly distributed fixing plates 502 installed on the outer wall of the collar 501 provide a mounting carrier for the pressure rollers 503, while ensuring that the multiple pressure rollers 503 are evenly distributed, so as to apply a uniform thrust to the multiple clamping components 8; the pressure roller 503 installed at one end of the fixing plate 502 distributes the thrust assembly The sliding friction between component 5 and clamping assembly 8 is converted into rolling friction, reducing the frictional force when the two move relative to each other, reducing component wear, and ensuring smoother thrust transmission, avoiding jamming of clamping assembly 8 due to excessive frictional resistance; the guide plates 504 on both sides of the outer wall of the collar 501 slide with the guide rod 9, further enhancing the guiding effect when the thrust assembly 5 moves, ensuring that the collar 501 drives the entire thrust assembly 5 to move stably along the guide rod 9, and ensuring that each pressure roller 503 acts synchronously on the corresponding clamping assembly 8.

[0021] In a preferred embodiment, the elastic component 7 includes a mounting rod 701 and a spring 702 sleeved on the outside of the mounting rod 701.

[0022] It should be noted that: the mounting rod 701 is fixedly installed on the inner wall of the mounting frame 6, providing mounting support and axial limit for the spring 702, preventing radial displacement or twisting of the spring 702 during extension and retraction; the spring 702, sleeved on the outside of the mounting rod 701, deforms under the tension of the clamping assembly 8 when the clamping assembly 8 is pushed and moved by the thrust assembly 5, storing elastic potential energy; when the thrust assembly 5 releases the thrust, the spring 702, relying on its own elastic restoring force, pulls the clamping assembly 8 to return to its axial position along the mounting rod 701, realizing the automatic reset function of the clamping assembly 8 without additional manual operation, thus improving the convenience of operation.

[0023] In a preferred embodiment, the clamping assembly 8 includes a slider 801 sleeved on one bottom end of the mounting rod 701, a connecting plate 802 mounted on one side outer wall of the slider 801, a clamping plate 803 mounted on one bottom end of the connecting plate 802, and a rubber pad 804 adhered to the bottom outer wall of the clamping plate 803.

[0024] It should be noted here that: the slider 801 is sleeved on one end of the bottom of the mounting rod 701 and can slide along the axial direction of the mounting rod 701. The inclined structure of one end of the slider 801 contacts the pressure roller 503 of the thrust assembly 5. When the pressure roller 503 moves with the thrust assembly 5, the pressure roller 503 rolls along the inclined surface of the slider 801, converting the axial thrust of the thrust assembly 5 into a force that pushes the slider 801 to move radially along the mounting rod 701; the connecting plate 802 installed on one side of the outer wall of the slider 801 transmits the movement of the slider 801 to the clamping plate 803, realizing power transmission; the bottom of the connecting plate 802... The clamping plate 803 installed at the end moves closer to the pipeline under the drive of the connecting plate 802. Through the coordinated action of multiple clamping plates 803, the pipeline is clamped and fixed. The rubber pad 804 bonded to the bottom outer wall of the clamping plate 803 increases the friction between the clamping plate 803 and the pipeline, improves clamping stability, and prevents the pipeline from sliding. On the other hand, the rubber pad 804 is elastic, which can avoid rigid contact between the clamping plate 803 and the pipeline, protect the outer wall of the pipeline from compression damage, and adapt to the clamping requirements of pipelines with different diameters, enhancing the versatility of the clamping assembly 8.

[0025] In a preferred embodiment, one end of the slider 801 has an inclined surface structure.

[0026] It should be noted here that the inclined structure at one end of the slider 801 serves as the force transmission medium between the thrust assembly 5 and the clamping assembly 8. When the pressure roller 503 of the thrust assembly 5 moves along the inclined surface, the axial thrust of the pressure roller 503 (along the axis of the quick connector 2) is decomposed into components perpendicular to the inclined surface and along the inclined surface by utilizing the inclination angle of the inclined surface. The component along the inclined surface pushes the slider 801 to move radially along the mounting rod 701, thereby driving the connecting plate 802 and the clamping plate 803 to move towards the pipeline, realizing the conversion of "axial thrust → radial clamping force". This ensures that the movement of the thrust assembly 5 can effectively drive the clamping assembly 8 to complete the clamping action. At the same time, the inclined structure can make the force transmission more stable and avoid damage to the components caused by excessive instantaneous impact force.

[0027] In a preferred embodiment, a plurality of equally spaced anti-slip strips 10 are installed on the outer wall of the internally threaded pipe 4.

[0028] It should be noted that the multiple equidistant anti-slip strips 10 installed on the outer wall of the internally threaded pipe 4 increase the friction between the operator's hand or tool and the outer wall of the internally threaded pipe 4, preventing slippage during rotation of the internally threaded pipe 4. Especially in the case of oil and moisture in the hydraulic system environment, the anti-slip strips 10 can significantly improve operational stability, allowing the operator to more easily and accurately control the rotation angle and speed of the internally threaded pipe 4, thereby precisely adjusting the moving distance of the thrust assembly 5, ensuring that the clamping force of the clamping assembly 8 on the pipeline is moderate, ensuring pipeline stability, and avoiding excessive clamping and damage to the pipeline.

[0029] Working principle: Connection and Expansion Stage: A quick connector 2 is installed on one side of the outer wall of the integrated hydraulic valve block body 1. With the help of the interface characteristics of the quick connector 2, temporary pipelines, test equipment or other hydraulic accessories can be quickly connected to it, providing a convenient channel for the commissioning, daily maintenance and functional expansion (such as adding monitoring branches) of the converter flue gas purification hydraulic servo system, and meeting the diverse usage needs of the system.

[0030] Clamping drive start-up stage: After the quick connector 2 completes the connection of the external pipeline, the operator uses the external thread 3 on the outer wall of the quick connector 2 and the screw connection with the internal thread pipe 4 to rotate the internal thread pipe 4 through the anti-slip strip 10 on the outer wall of the internal thread pipe 4 (to increase the friction between the hand and the pipe wall and prevent slippage). The thrust component 5, which is sleeved on the outer wall of the internal thread pipe 4, moves axially through the thread transmission.

[0031] In the thrust assembly guiding and transmission stage: the guide rods 9 on both sides of the outer wall of the quick connector 2 and the guide plates 504 on both sides of the collar 501 in the thrust assembly 5 form a sliding fit, which limits the radial offset of the thrust assembly 5 and ensures that it moves stably along the guide rods 9; the fixing plate 502 on the outer wall of the collar 501 drives the pressure roller 503 to move synchronously, and the pressure roller 503 contacts the slider 801 of the clamping assembly 8, converting sliding friction into rolling friction, reducing component wear, and ensuring smooth thrust transmission.

[0032] During the clamping assembly operation phase: One end of the slider 801 has an inclined structure. When the pressure roller 503 rolls along the inclined surface, it converts the axial thrust into a force that pushes the slider 801 to move radially along the mounting rod 701 in the elastic assembly 7. The slider 801 drives the clamping plate 803 to move closer to the pipeline through the connecting plate 802. Multiple clamping plates 803 work together to clamp and fix the external pipeline of the quick connector 2. The rubber pad 804 at the bottom of the clamping plate 803 increases the friction with the pipeline, improves the clamping stability, and avoids damage to the pipeline from rigid contact.

[0033] Reset phase: During the clamping process, the slider 801 moves the spring 702 outside the tension mounting rod 701, allowing the spring 702 to store elastic potential energy; when it is necessary to release the pipeline, the internal threaded tube 4 is rotated in the opposite direction, the thrust assembly 5 releases the thrust on the slider 801, the spring 702 releases its elastic potential energy, and pulls the slider 801, connecting plate 802 and clamping plate 803 to reset, releasing the clamping of the pipeline and facilitating pipeline disassembly.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
