Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, specifically to a steel pipe lining concrete pouring equipment and its usage method. Background Technology

[0002] Concrete-filled steel tubes (CFST) are structural members formed by filling concrete into a steel tube, where the steel tube and the core concrete work together to withstand external loads. Based on cross-sectional shape, they can be classified as circular CFST, square / rectangular CFST, and polygonal CFST. Concrete has high compressive strength but weak bending resistance, while steel, especially structural steel, has strong bending resistance and good elasticity / plasticity, but is prone to instability and loss of axial compressive strength under pressure. CFST combines the advantages of both materials, placing the concrete under lateral compression, which can significantly increase its compressive strength. Simultaneously, the presence of concrete increases the stiffness of the steel tube. Together, they greatly enhance the load-bearing capacity.

[0003] During the pouring of steel pipes, the injected concrete is typically guided through a hopper to continuously flow into the inner lining of the pipe. During this process, some air bubbles usually remain inside the concrete. Typically, a vibrator is used to defoam the concrete after pouring, but this usually requires adding more concrete, increasing the difficulty of defoaming. Therefore, we propose a concrete pouring device for steel pipe linings and its application method. Summary of the Invention

[0010] Preferably, a connecting block is fixedly installed on the surface of the toothed plate frame. There are two connecting blocks, and a guide rod is fixedly installed on the opposite side of the two connecting blocks.

[0011] Preferably, a fixing block is fixedly installed on the top of the fixing plate, a positioning rod is threadedly connected to the inner wall of the fixing block, a positioning groove is opened on the surface of the guide rod, and the inner cavity of the positioning groove is threadedly connected to the surface of the positioning rod.

[0012] Preferably, the bottom of the fixing plate is provided with a replacement mechanism, the replacement mechanism including a fixing groove, the fixing groove being opened at the bottom of the fixing plate, a clamping plate being slidably connected to the inner wall of the fixing groove, the surface of the clamping plate being slidably connected to the inner wall of the fixing groove, and a connecting rod being threadedly connected to the inner wall of the fixing plate, the inner wall of the connecting rod being threadedly connected to the surface of the clamping plate.

[0013] Preferably, the inner wall of the fixing groove is provided with a docking groove, and a docking block is fixedly installed on the top of the card plate, and the inner cavity of the docking groove is slidably connected to the surface of the docking block.

[0014] A method for using a concrete pouring device for steel pipe lining includes the following steps: S1: Place the fixing plate stably on top of the steel pipe, ensuring accurate positioning and firm fixation. With the help of an external concrete pump, slowly inject concrete from the hopper into the inner cavity of the steel pipe. During the injection process, promptly expel the gas from the inner cavity of the steel pipe through the exhaust pipe to avoid air blockage and ensure smooth filling of the concrete, thus completing the initial concrete pouring of the steel pipe. S2: When the half gear rotates, its teeth mesh with the teeth of the first tooth plate. Under the action of meshing force, the first tooth plate slides in the sliding groove in a predetermined direction, stretching the tension spring connected to it, causing the tension spring to produce elastic deformation and store elastic potential energy. When the teeth of the half gear disengage from the teeth of the first tooth plate, the tension spring releases the reaction force, pulling the first tooth plate to quickly return to its original position, driving the striking rod to move quickly and strike the outer wall of the steel pipe. The half gear continues to rotate, realizing the continuous striking of the steel pipe by the striking rod, making the concrete inside the steel pipe denser, reducing air bubbles and voids, and improving the quality of concrete and structural strength. S3: The motor is started by an external power supply, which drives the first gear to rotate. The first gear meshes with the second toothed plate, causing the second toothed plate to move and drive the placement plate to move upward. During the upward movement of the placement plate, the second gear meshes with the teeth on the inner side of the toothed plate frame and rotates automatically under the drive of the teeth, thereby driving the half gear to rotate. When the placement plate moves upward to the maximum stroke position, the teeth of the half gear disengage from the teeth of the first toothed plate. Then, the electric push rod is started to push the support plate to move, causing the second gear to change position and mesh with the teeth on the other side of the toothed plate frame. The direction of motor rotation is changed so that it rotates in the opposite direction, causing the first gear to rotate in the opposite direction, thereby causing the second toothed plate to move in the opposite direction, causing the placement plate to move downward. At this time, because the second gear is meshed with the teeth on the other side of the toothed plate frame, it maintains the same direction of rotation as when it was rising, driving the half gear to rotate, so that the striking rod works again. Through the up and down movement of the placement plate, the striking rod strikes the steel pipe at each stage, increasing the vibration frequency and efficiency, and improving the quality of concrete pouring. S4: The clamping plate slides on the inner wall of the fixing groove and is in close contact with the outer surface of the steel pipe, providing additional support and constraint for the fixing plate and enhancing stability. The inner wall of the connecting rod is threaded to the surface of the clamping plate and fixed to the inner wall of the fixing plate. When the clamping plate needs to be replaced, rotate the connecting rod to cancel the threaded connection between it and the clamping plate, so as to separate the clamping plate from the fixing groove and complete the quick removal. When installing a new clamping plate, put it into the fixing groove and rotate the connecting rod in the opposite direction to re-establish the threaded connection. The whole replacement process is simple and convenient, which can effectively improve the efficiency of equipment maintenance.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a vibration unit to continuously strike a steel pipe with a striking rod. The vibration generated by this continuous striking makes the concrete inside the steel pipe more compact, effectively reducing air bubbles and voids inside the concrete, thereby significantly improving the overall quality and structural strength of the concrete after pouring.

[0016] This invention, by setting an adjustment unit, uses the second gear to rotate in the same direction as when it moves down and up, thereby driving the half gear to maintain the corresponding rotation, enabling the striking rod to work again. Through the process of the placement plate moving up and down, the striking rod can strike the steel pipe at each stage of movement, effectively increasing the frequency and efficiency of vibration, and helping to improve the pouring quality of concrete inside the steel pipe.

[0017] This invention, by setting up a replacement mechanism, ensures that the clamping plate makes close contact with the outer surface of the steel pipe, providing additional support and constraint for the fixing plate. This further enhances the stability of the fixing plate during operation, ensuring that the fixing plate will not shake or shift during subsequent operations such as concrete pouring. Since the connecting rod and the clamping plate are connected by a thread, the clamping plate can be replaced simply by rotating the connecting rod. The entire replacement process is simple and convenient, effectively improving the maintenance efficiency of the equipment. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 7 The present invention provides a technical solution: a steel pipe lining concrete pouring equipment, including a main body 1, the main body 1 including a fixing plate 11, a hopper 12 fixedly connected to the top of the fixing plate 11, an exhaust pipe 13 fixedly connected to the top of the fixing plate 11, and an auxiliary mechanism 2 provided at the bottom of the fixing plate 11.

[0022] As a further limitation of the present invention, the vibration unit 21 includes a placement plate 2101, a sliding groove 2102 is provided on the top of the placement plate 2101, a first toothed plate 2103 is slidably connected to the inner cavity of the sliding groove 2102, a tension spring 2107 is fixedly installed in the inner cavity of the sliding groove 2102, one end of the tension spring 2107 is fixedly connected to the bottom of the first toothed plate 2103, a support plate 2104 is slidably connected to the inner wall of the placement plate 2101, a half gear 2105 is rotatably connected to the inner wall of the support plate 2104, the half gear 2105 is used in conjunction with the teeth of the first toothed plate 2103, and a striking rod 2106 is fixedly installed on one side of the first toothed plate 2103. By setting the vibration unit 21, the continuous striking of the steel pipe by the striking rod 2106 can make the concrete in the steel pipe more compact, effectively reduce the air bubbles and voids inside the concrete, and thus significantly improve the overall quality and structural strength of the concrete after pouring.

[0023] The inner cavity of the sliding groove 2102 is provided with a guide groove 2108, and a guide block 2109 is fixedly installed on the surface of the first toothed plate 2103. The surface of the guide block 2109 is slidably connected to the inner cavity of the guide groove 2108. Through the slidable connection between the guide groove 2108 and the guide block 2109, the movement of the first toothed plate 2103 can be guided, so that the first toothed plate 2103 can move laterally.

[0024] A buffer pad 2110 is fixedly installed at one end of the striking rod 2106. The buffer pad 2110 is made of rubber. The buffer pad 2110 reduces the impact force generated by the striking rod 2106 and prevents the steel pipe from deforming.

[0025] The specific implementation method of this embodiment is as follows: When performing concrete pouring in steel pipe, the fixing plate 11 is first placed stably on the top of the steel pipe to ensure its accurate position and firm fixation. Then, with the help of an external concrete pump, concrete is slowly injected from the hopper 12 into the inner cavity of the steel pipe. During the concrete injection process, in order to avoid air resistance forming in the inner cavity of the steel pipe and affecting the concrete filling effect, the gas in the inner cavity of the steel pipe needs to be discharged in time through the exhaust pipe 13, so as to smoothly realize the concrete pouring of the steel pipe. When the half gear 2105 rotates, its teeth will mesh with the teeth on the first tooth plate 2103. Under the action of meshing force, the first tooth plate 2103 will slide in the inner cavity of the sliding groove 2102 along a predetermined direction. As the first tooth plate 2103 slides, the tension spring 2107 connected to it will be gradually stretched, generating elasticity. The half gear 2105 deforms and stores elastic potential energy. When the teeth of the half gear 2105 continue to rotate and disengage from the teeth of the first tooth plate 2103, the reaction force generated by the tension spring 2107 due to previous stretching will be released immediately. Under the pull of this reaction force, the first tooth plate 2103 will quickly return to its initial position. During the return process, the first tooth plate 2103 will drive the connected striking rod 2106 to move rapidly, causing the striking rod 2106 to strike the outer wall of the steel pipe. Through the continuous rotation of the half gear 2105, the above process will be repeated continuously, realizing the continuous striking of the steel pipe by the striking rod 2106. The vibration generated by this continuous striking can make the concrete inside the steel pipe more compact, effectively reducing air bubbles and voids inside the concrete, thereby significantly improving the overall quality and structural strength of the concrete after pouring.

[0026] Example 2: Please refer to Figures 1 to 5 The present invention provides a technical solution: a steel pipe lining concrete pouring equipment. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The auxiliary mechanism 2 also includes an adjustment unit 22, which is disposed at the bottom of the fixed plate 11. The adjustment unit 22 is used to assist the vibration unit 21 in adjustment.

[0027] As a further limitation of the present invention, the adjustment unit 22 includes a motor 2201, which is fixedly mounted on one side of the placement plate 2101. A first gear 2202 is fixedly mounted on the output end of the motor 2201. A second toothed plate 2203 is slidably connected to the inner wall of the fixed plate 11, and the teeth of the second toothed plate 2203 mesh with the teeth of the first gear 2202. A toothed plate frame 2204 is slidably connected to the inner wall of the fixed plate 11. A second gear 2205 is fixedly mounted on the surface of the half gear 2105, and the second gear 2205 cooperates with the teeth of the toothed plate frame 2204 for placement. An electric push rod 2206 is fixedly installed on the top of the plate 2101. The telescopic end of the electric push rod 2206 is fixedly connected to one side of the support plate 2104. By setting an adjustment unit 22, the second gear 2205 rotates in the same direction when it moves down and up, thereby driving the half gear 2105 to maintain the corresponding rotation, so that the striking rod 2106 can work again. Through the process of the plate 2101 moving up and down, the striking rod 2106 can strike the steel pipe in each movement stage, which effectively increases the frequency and efficiency of vibration and helps to improve the pouring quality of concrete in the steel pipe.

[0028] Two connecting blocks 2207 are fixedly installed on the surface of the toothed frame 2204. A guide rod 2208 is fixedly installed on the opposite side of the two connecting blocks 2207. The surface of the guide rod 2208 is slidably connected to the inner wall of the placement plate 2101. By setting the connecting blocks 2207, the guide rod 2208 can be supported. By guiding the guide rod 2208, the placement plate 2101 can be kept vertical and moved up and down.

[0029] A fixing block 2209 is fixedly installed on the top of the fixing plate 11. A positioning rod 2210 is threadedly connected to the inner wall of the fixing block 2209. A positioning groove 2211 is opened on the surface of the guide rod 2208. The inner cavity of the positioning groove 2211 is threadedly connected to the surface of the positioning rod 2210. The positioning rod 2210 is supported by the fixing block 2209. The threaded connection between the positioning rod 2210 and the positioning groove 2211 can fix the position of the adjusted guide rod 2208, thereby fixing the position of the toothed plate frame 2204 and the second toothed plate 2203. The length of the second toothed plate 2203 can be adjusted according to the length of the steel pipe.

[0030] The specific implementation of this embodiment is as follows: During the operation of the striking rod 2106, the motor 2201 is first started by an external power supply. After the motor 2201 starts, it drives the first gear 2202 to start rotating. Since the first gear 2202 meshes with the second gear plate 2203, the second gear plate 2203 will move accordingly under the rotation of the first gear 2202, thereby driving the placement plate 2101 to move upward. During the upward movement of the placement plate 2101, the second gear 2205 meshes with the second gear plate 2203. The teeth on the inner side of the plate frame 2204 are in a meshing state. As the placement plate 2101 rises, the second gear 2205 will automatically rotate under the drive of the teeth, and the half gear 2105 will also rotate accordingly. When the placement plate 2101 moves upward to the maximum stroke position, the teeth of the half gear 2105 are in a non-contact state with the teeth of the first gear plate 2103, that is, the two are disengaged. Then, the electric push rod 2206 is started again by the external power supply, and the electric push rod 2206 pushes the support plate 2104. The movement of the support plate 2104 causes the second gear 2205 to change position, meshing with the teeth on the other side of the toothed plate frame 2204. Then, the rotation direction of the motor 2201 is reversed, causing the first gear 2202 to rotate in the opposite direction. The first gear 2202 meshes with the second toothed plate 2203, causing the second toothed plate 2203 to move in the opposite direction, thus moving the placement plate 2101 downwards. Since the second gear 2205 is now meshing with the teeth on the other side of the toothed plate frame 2204, it maintains the same rotation direction as when it was rising, driving the half gear 2105 to rotate accordingly. This allows the striking rod 2106 to work again. Through the up-and-down movement of the placement plate 2101, the striking rod 2106 can strike the steel pipe at each stage of movement, effectively increasing the vibration frequency and efficiency, and helping to improve the quality of concrete pouring inside the steel pipe.

[0031] Example 3: Please refer to Figure 1 , Figure 6 and Figure 7 The present invention provides a technical solution: a steel pipe lining concrete pouring equipment. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A replacement mechanism 3 is provided at the bottom of the fixed plate 11. The replacement mechanism 3 is used to support the position of the fixed plate 11.

[0032] As a further limitation of the present invention, the replacement mechanism 3 includes a fixing groove 31, which is formed at the bottom of the fixing plate 11. A clamping plate 32 is slidably connected to the inner wall of the fixing groove 31, and the surface of the clamping plate 32 is slidably connected to the inner wall of the fixing groove 31. A connecting rod 33 is threadedly connected to the inner wall of the fixing plate 11, and the inner wall of the connecting rod 33 is threadedly connected to the surface of the clamping plate 32. By setting the replacement mechanism 3, the clamping plate 32 will be in close contact with the outer surface of the steel pipe, which can provide additional support and constraint for the fixing plate 11, further enhancing the stability of the fixing plate 11 during operation, and ensuring that the fixing plate 11 will not shake or shift during subsequent operations such as concrete pouring. Since the connecting rod 33 and the clamping plate 32 are connected by threads, the replacement of the clamping plate 32 can be completed by rotating the connecting rod 33. The entire replacement process is simple and convenient, which can effectively improve the maintenance efficiency of the equipment.

[0033] The inner wall of the fixed groove 31 is provided with a docking groove 34, and a docking block 35 is fixedly installed on the top of the clamping plate 32. The inner cavity of the docking groove 34 is slidably connected to the surface of the docking block 35. Through the slidable connection between the docking block 35 and the docking groove 34, the clamping plate 32 can accurately enter the inner cavity of the fixed groove 31, ensuring the accuracy of docking.

[0034] The specific implementation of this embodiment is as follows: When the fixing plate 11 is placed on top of the steel pipe, the clamping plate 32 provided on the fixing plate 11 will be in close contact with the outer surface of the steel pipe, providing additional support and constraint for the fixing plate 11, further enhancing the stability of the fixing plate 11 during operation, and ensuring that the fixing plate 11 will not shake or shift during subsequent operations such as concrete pouring. However, after long-term use, the clamping plate 32 may experience wear, deformation, etc., affecting its fixing effect, at which point it needs to be replaced. Since the connecting rod 33 and the clamping plate 32 are connected by a threaded connection, by rotating the connecting rod 3... 3. The connecting rod 33 can be gradually unscrewed from the threaded hole on the clamping plate 32, thereby canceling the threaded connection between the two. When the connecting rod 33 and the clamping plate 32 are completely disengaged from the threaded connection, the clamping plate 32 is no longer constrained by the connecting rod 33. At this time, the clamping plate 32 can be easily removed from the fixing groove 31 on the fixing plate 11, realizing the quick removal of the clamping plate 32. Then, the new clamping plate 32 is installed into the fixing groove 31, and the connecting rod 33 is rotated in the opposite direction to re-establish the threaded connection with the new clamping plate 32, thus completing the replacement of the clamping plate 32. The whole replacement process is simple and convenient, which can effectively improve the maintenance efficiency of the equipment.

[0035] A method for using a concrete pouring device for steel pipe lining includes the following steps: S1: Place the fixing plate 11 stably on the top of the steel pipe, ensuring accurate positioning and firm fixation. With the help of an external concrete pump, slowly inject concrete from the hopper 12 into the inner cavity of the steel pipe. During the injection process, promptly discharge the gas in the inner cavity of the steel pipe through the exhaust pipe 13 to avoid air blockage and ensure smooth filling of the concrete, thus completing the initial concrete pouring of the steel pipe. S2: When the half gear 2105 rotates, its teeth mesh with the teeth of the first toothed plate 2103. Under the action of the meshing force, the first toothed plate 2103 slides in the sliding groove 2102 in a predetermined direction, stretching the tension spring 2107 connected to it, causing the tension spring 2107 to undergo elastic deformation and store elastic potential energy. When the teeth of the half gear 2105 disengage from the teeth of the first toothed plate 2103, the tension spring 2107 releases the reaction force, pulling the first toothed plate 2103 to quickly return to its original position, driving the striking rod 2106 to move quickly and strike the outer wall of the steel pipe. The half gear 2105 continues to rotate, realizing the continuous striking of the steel pipe by the striking rod 2106, making the concrete inside the steel pipe denser, reducing air bubbles and voids, and improving the quality of concrete and structural strength. S3: Start motor 2201 via external power supply, driving first gear 2202 to rotate. First gear 2202 meshes with second gear plate 2203, causing second gear plate 2203 to move and driving placement plate 2101 to move upward. During the upward movement of placement plate 2101, second gear 2205 meshes with the inner teeth of gear plate frame 2204, automatically rotating under the drive of the teeth, thereby driving half gear 2105 to rotate. When placement plate 2101 moves upward to the maximum stroke position, the teeth of half gear 2105 disengage from the teeth of first gear plate 2103. Then, start electric push rod 2206 to push support plate 2104 to move, driving second gear 2205 to rotate. Gear 2205 changes position so that it meshes with the teeth on the other side of the toothed plate frame 2204, changing the rotation direction of motor 2201 so that it rotates in the opposite direction, driving the first gear 2202 to rotate in the opposite direction, which in turn drives the second toothed plate 2203 to move in the opposite direction, causing the placement plate 2101 to move downward. At this time, the second gear 2205, because it is meshed with the teeth on the other side of the toothed plate frame 2204, maintains the same rotation direction as when it was rising, driving the half gear 2105 to rotate, so that the striking rod 2106 works again. Through the up and down movement of the placement plate 2101, the striking rod 2106 strikes the steel pipe at each stage, increasing the vibration frequency and efficiency, and improving the quality of concrete pouring. S4: The clamping plate 32 slides on the inner wall of the fixing groove 31 and is in close contact with the outer surface of the steel pipe, providing additional support and constraint for the fixing plate 11 and enhancing stability. The inner wall of the connecting rod 33 is threadedly connected to the surface of the clamping plate 32 and fixed to the inner wall of the fixing plate 11. When the clamping plate 32 needs to be replaced, the connecting rod 33 is rotated to cancel the threaded connection between it and the clamping plate 32, thereby separating the clamping plate 32 from the fixing groove 31 and completing the quick removal. When installing a new clamping plate 32, it is placed into the fixing groove 31, and the connecting rod 33 is rotated in the opposite direction to re-establish the threaded connection. The entire replacement process is simple and convenient, which can effectively improve the efficiency of equipment maintenance.

The inner cavity of the docking groove (34) is slidably connected to the surface of the docking block (35).

10. A method of using a steel pipe lining concrete pouring equipment, characterized in that: Includes the following steps: S1: Place the fixing plate (11) on the top of the steel pipe to ensure that the position is accurate and the fixing is firm. With the help of an external concrete pump, slowly inject concrete from the hopper (12) into the inner cavity of the steel pipe. During the injection process, the gas in the inner cavity of the steel pipe is discharged in time through the exhaust pipe (13) to avoid forming air resistance, ensure that the concrete is filled smoothly, and complete the initial concrete pouring of the steel pipe. S2: When the half gear (2105) rotates, its teeth mesh with the teeth of the first tooth plate (2103). Under the action of meshing force, the first tooth plate (2103) slides in the sliding groove (2102) in a predetermined direction, stretching the tension spring (2107) connected to it, causing the tension spring (2107) to produce elastic deformation and store elastic potential energy. When the teeth of the half gear (2105) disengage from the teeth of the first tooth plate (2103), the tension spring (2107) releases the reaction force, pulling the first tooth plate (2103) to quickly reset, driving the striking rod (2106) to move quickly and strike the outer wall of the steel pipe. The half gear (2105) continues to rotate, realizing the continuous striking of the steel pipe by the striking rod (2106), making the concrete inside the steel pipe denser, reducing air bubbles and voids, and improving the quality of concrete and structural strength. S3: Start the motor (2201) via external power supply, driving the first gear (2202) to rotate. The first gear (2202) meshes with the second gear plate (2203), causing the second gear plate (2203) to move and drive the placement plate (2101) to move upward. During the upward movement of the placement plate (2101), the second gear (2205) meshes with the inner teeth of the gear plate frame (2204), and rotates automatically under the drive of the teeth, thereby driving the half gear (2105) to rotate. When the placement plate (2101) moves upward to the maximum stroke position, the teeth of the half gear (2105) disengage from the teeth of the first gear plate (2103). Then, start the electric push rod (2206) to push the support plate (2104) to move, driving the second gear (2205) to rotate. The second gear (2205) is moved to a different position so that it meshes with the teeth on the other side of the toothed plate frame (2204), and the rotation direction of the motor (2201) is changed so that it rotates in the opposite direction, driving the first gear (2202) to rotate in the opposite direction, which in turn drives the second toothed plate (2203) to move in the opposite direction, causing the placement plate (2101) to move downward. At this time, the second gear (2205) is meshed with the teeth on the other side of the toothed plate frame (2204) and maintains the same rotation direction as when it is rising, driving the half gear (2105) to rotate, so that the striking rod (2106) works again. Through the up and down movement of the placement plate (2101), the striking rod (2106) strikes the steel pipe at each stage, increasing the vibration frequency and efficiency, and improving the quality of concrete pouring. S4: The card plate (32) slides on the inner wall of the fixed groove (31) and is in close contact with the outer surface of the steel pipe, providing additional support and constraint for the fixed plate (11) and enhancing stability. The inner wall of the connecting rod (33) is threaded to the surface of the card plate (32) and fixed to the inner wall of the fixed plate (11). When the card plate (32) needs to be replaced, the connecting rod (33) is rotated to cancel the threaded connection between it and the card plate (32), thereby separating the card plate (32) from the fixed groove (31) and completing the quick removal. When installing a new card plate (32), it is placed in the fixed groove (31), and the connecting rod (33) is rotated in the opposite direction to re-establish the threaded connection. The entire replacement process is simple and convenient, which can effectively improve the equipment maintenance efficiency.
