[0026] According to the above technical solution, the plugging includes the following steps:

[0027] S1. Push the moving seat to the outside of the pipeline, and ensure that the axis of the semi-circular clamping seat corresponds to the axis of the pipeline. Then start the double-shaft motor, and through the transmission of power, push the two semi-circular clamping seats to move and fit synchronously;

[0028] S2. Start the rotating motor, and through the combined transmission of the transmission belt, guide rod, positioning rod and bevel gear, make the clamping plates on the two fixed frames move together to clamp the pipeline;

[0029] S3. Start the electric push rod, push the fitting plate to move to clamp the pipeline. Then, on the backing plate, a sealing ring is combined between the limiting plate and the pipeline, and the limiting plate clamps the sealing ring to make the inner wall of the sealing ring fit with the outside of the pipeline;

[0030] S4. Start the electric hydraulic rod to push the top plate, fitting plate, backing plate, limiting plate and sealing ring to rise, forcing the sealing ring to be embedded into the gap between the reserved pipe and the pipeline;

[0031] S5. Then fill concrete or other suitable plugging materials from above the floor to ensure that the sealing ring is tightly combined with the floor structure to form a complete plugging system.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use:

[0033] 1. A moving and clamping limiting mechanism is provided. Through the cooperation of the transmission rod, transmission gear, sleeve and internal tooth belt, it is convenient for the double-shaft motor to drive the sleeves at both ends of the moving seat to rotate synchronously, so as to push the adjusting screw rods at both ends of the moving seat to move relatively or in the opposite direction synchronously. And through the cooperation of the fixing plate, support block and universal wheel, push the two semi-circular clamping seats to move synchronously, away from or close to the pipeline;

[0034] Through the cooperation of bevel gears, it is convenient for the positioning rod to drive the rotating cylinder to rotate, push the push rod and the clamping plate to move, and closely fit with the outside of the pipeline. At the same time, through the combined transmission of the driving gear, transmission belt, guide rod, positioning rod and bevel gear, the clamping plates on the two fixed frames move synchronously, which is convenient for clamping and fixing pipelines of different sizes, ensuring the stability of the pipeline, and thus preventing deviation during plugging;

[0035] In addition, according to the fitting position of the splint and the pipeline, the pushing frame and the supporting wheels can be used to push the moving seat to move outside the pipeline, so that the axes of the two semi-circular clamping seats correspond to the axis of the pipeline, preventing deviation, ensuring the clamping effect of the splint. At the same time, the driving rod is rotated to drive the supporting wheels to lift, adjusting the tilt angle and height of the moving seat to ensure the stability of the moving seat on the ground;

[0036] Due to the contraction characteristic of the tension spring, the ejector rod and the anti-deviation plate are driven to move, forcing the anti-deviation plate to move and fit with the pipeline, further clamping the pipeline and ensuring the stability between the arc-shaped frame and the pipeline;

[0037] 2. The lifting and supporting mechanism is set. The electric push rod is used to push the fitting plate to move, clamping the pipeline. During the movement of the fitting plate, the limiting rod is used for limiting to prevent the fitting plate from deviating, ensuring the clamping effect. Through the cooperation of the backing plate and the limiting plate, it is convenient to combine the sealing ring outside the pipeline, and then through the extrusion of the limiting plate, the inner wall of the sealing ring fits with the outside of the pipeline;

[0038] The electric hydraulic rod is used to push the top plate, the partition plate, the fitting plate, the limiting plate and the sealing ring to slide up along the outside of the pipeline. When the limiting plate and the sealing ring contact the top of the floor, the limiting plate is extruded, causing the support spring and the telescopic sleeve rod to contract, driving the limiting plate to slide down, while the backing plate continues to push the sealing ring up, enabling the sealing ring to be embedded into the gap between the reserved pipe and the pipeline and supporting it, facilitating the subsequent filling of fireproof materials and improving the convenience;

[0039] The rollers reduce the friction between the fitting plate and the pipeline, ensuring the lifting effect of the fitting plate. At the same time, the return spring facilitates the sliding of the slider and the rollers inside the chute, adjusting the distance between the fitting plate and the pipeline as needed, enabling the limiting plate to clamp sealing rings of different thicknesses and improving the adaptability;

[0040] Due to the telescopic characteristic of the telescopic spring, the plug board is pushed to slide and inserted into the slot, limiting the plug board and the L-shaped plate, improving the fitting effect between the two arc-shaped frames and the two top plates, preventing loosening and separation, and ensuring the clamping effect.

[0041] To sum up, through the cooperation of the moving, clamping and limiting mechanism and the lifting and supporting mechanism, the annular sealing of the pipeline passing through the floor slab is realized through mechanical operation, reducing the workload of construction workers, reducing the occurrence of the phenomenon of incomplete sealing caused by improper operation, and at the same time reducing the existing safety hazards, improving the efficiency. At the same time, it ensures that the sealing ring can be closely fitted into the gap between the pipeline and the reserved pipe, guaranteeing the subsequent filling effect.

[0077] Working principle and usage process of the present invention: First, start the dual-axis motor 308 to drive the transmission rod 309 to rotate. Then, through the cooperation of the transmission gear 310, the power is transmitted to drive the sleeves 301 at both ends of the moving seat 1 to rotate. At the same time, with the cooperation of the internal tooth belt 302, the power is further transmitted, so that the two sleeves 301 on the same side at both ends of the moving seat 1 rotate together. Then, because the adjusting screw rod 303 is threadedly connected to the sleeve 301 and the threaded rotation directions of the two opposite adjusting screw rods 303 are opposite, when the sleeve 301 rotates, the two semi-ring clamping seats 305 are pushed by the adjusting screw rod 303 to move and open synchronously, away from the pipeline.

[0078] Next, through the cooperation of the pushing frame 2 and the supporting wheel 313, it is convenient to push the moving seat 1 to move to the outside of the pipeline, forcing the two semi-ring clamping seats 305 to correspond to the pipeline. Then, start the dual-axis motor 308 to reverse, and through the transmission of the transmission component, the two semi-ring clamping seats 305 move and close synchronously, approaching the pipeline. And during the movement of the semi-ring clamping seat 305, through the cooperation of the fixing plate 304, the supporting block 306 and the universal wheel 307, support is provided to ensure the stability of the semi-ring clamping seat 305. At the same time, rotate the driving rod 312 on the extension plate 311 to drive the supporting wheel 313 to rise, adjusting the inclination angle and height of the moving seat 1 to ensure the stability of the moving seat 1 on the ground.

[0079] Next, drive the positioning rod 318 to rotate through the rotating motor 328, and use the transmission of the bevel gear 322 to force the positioning rod 318 to push the rotating cylinder 315 to rotate. At the same time, when the positioning rod 318 rotates, the power is transmitted by using the driving gear 320, so that the two adjacent positioning rods 318 rotate together, and thus together push the rotating cylinder 315 to rotate, forcing the push rod 316 and the clamping plate 317 to move and fit tightly against the outside of the pipeline.

[0080] In addition, through the transmission of the transmission belt 321, the guide rod 319 is driven to rotate, and then through the cooperation of the driving gear 320, the two adjacent guide rods 319 rotate synchronously, further transmitting the power, so that the two clamping plates 317 on one fixing frame 314 move together. When the two semi-ring clamping seats 305 close, the two adjacent guide rods 319 on the two fixing frames 314 approach, making the driving gear 320 engage, facilitating the power transmission. Then, through the cooperation of the transmission belt 321, the positioning rod 318 and the driving gear 320, the power is transmitted in sequence, so that the four clamping plates 317 on the two semi-ring clamping seats 305 move synchronously to clamp pipelines of different sizes, improving the stability of the pipeline. Furthermore, during plugging, it can prevent deviation. At the same time, the positions of the moving seat 1 and the semi-ring clamping seat 305 can be adjusted according to the fitting position of the clamping plate 317 and the pipeline, so that the axes of the semi-ring clamping seat 305, the pipeline and the reserved pipe correspond to each other.

[0081] Next, after the adjustment is completed, by virtue of the contracting property of the tension spring 327, the ejector rod 325 and the anti-deviation plate 326 are moved, forcing the anti-deviation plate 326 to move and fit with the pipeline, further clamping the pipeline, and ensuring the stability between the arc-shaped frame 324 and the pipeline;

[0082] Next, the electric push rod 404 is started to push the fitting plate 405 to move, so that the fitting plate 405 clamps the pipeline. And during the movement of the fitting plate 405, through the limitation of the limiting rod 406, the stability of the fitting plate 405 is ensured, and the clamping effect is improved. Then, on the backing plate 407, the sealing ring is assembled and combined between the limiting plate 408 and the pipeline, forcing the inner wall of the limiting plate 408 to fit with the outer side of the sealing ring, and the inner wall of the sealing ring to fit with the outer side of the pipeline;

[0083] Next, the electric hydraulic rod 401 is started to push the top plate 402, the partition plate 403, the fitting plate 405, the limiting plate 408 and the sealing ring to slide and rise along the outer side of the pipeline. When the limiting plate 408 and the sealing ring contact the top of the floor, then as the electric hydraulic rod 401 continues to extend, the limiting plate 408 is extruded, forcing the support spring 410 and the telescopic sleeve rod 409 to contract, while the backing plate 407 continues to push the sealing ring to rise, forcing the sealing ring to be embedded into the gap between the reserved pipe and the pipeline, thereby sealing the gap between the reserved pipe and the pipeline, facilitating the subsequent filling of fireproof materials and improving the convenience;

[0084] In addition, when the fitting plate 405 moves up and down along the pipeline, through the cooperation of the rollers 415, the friction between the fitting plate 405 and the pipeline is reduced, ensuring the effect of the up and down movement of the fitting plate 405. In addition, by virtue of the telescopic property of the return spring 416, it is convenient to drive the slider 414 and the rollers 415 to slide along the fixed rod 413 inside the chute 412, so as to adjust the distance between the fitting plate 405 and the pipeline as required, enabling the limiting plate 408 to clamp sealing rings of different thicknesses and improving the adaptability;

[0085] Finally, when the two semi-ring clamping seats 305 are fitted, the two arc-shaped frames 324 and the two top plates 402 are fitted. At the same time, by virtue of the telescopic property of the telescopic spring 419, the plug board 420 is pushed to slide and inserted into the slot 421, limiting the plug board 420 and the L-shaped plate 417, improving the fitting effect of the two arc-shaped frames 324 and the two top plates 402, preventing loosening and separation, and ensuring the clamping effect.

[0086] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features.
