Description

Technical Field

[0001] This invention belongs to the field of concrete jacking pipe forming technology, and more specifically, it relates to a concrete jacking pipe pouring equipment and method with a built-in corrugated steel skeleton. Background Technology

[0002] Concrete jacking pipes are formed by centrifugal casting, which mainly utilizes the centrifugal force generated by high-speed rotation to compact the concrete and form a uniform pipe wall structure. In addition, centrifugal forming can precisely control the pipe size and ensure a smooth inner wall, making it suitable for pipeline projects with high requirements for structural strength and sealing.

[0003] Currently, the following problems still exist in the forming of concrete jacking pipes: 1. The inability to assist in increasing the contact area leads to poor stability during equipment use. Although some equipment improves stability by increasing the support length, it is inconvenient for turnover and transportation; 2. The lack of a corrugated steel frame positioning structure results in a lot of time being spent adjusting the corrugated steel frame, affecting the production efficiency of concrete jacking pipes; 3. The inability to automatically press the inner wall of the concrete jacking pipe results in an insufficiently smooth inner wall after forming. Summary of the Invention

[0004] This disclosure relates to a concrete jacking pipe pouring device and method with a built-in corrugated steel skeleton, comprising a support positioning component, a centrifugal pouring component, a centrifugal driving component, and a pouring pressing component.

When the operator rotates the adjusting screw clockwise, the screw moves the skeleton support block upwards, providing auxiliary support to the right end of the corrugated steel skeleton, facilitating its connection with the annular baffle b. The circular pressing roller contacts the centrifugal pouring shell and the annular baffle b, pressing the inner wall of the concrete jacking pipe, resulting in a smoother inner wall after molding. This solves the problems of insufficient contact area, time-consuming adjustments to the corrugated steel skeleton, and an insufficiently smooth inner wall of the molded concrete jacking pipe.

[0014] In another aspect, this disclosure provides a method for pouring concrete jacking pipes with a built-in corrugated steel skeleton, the method comprising the following steps: 1) Secure the support positioning frame with four bolts and four mounting holes, and then connect the external concrete conveying hose to the hose connector; 2) Insert the four auxiliary support plates into the support positioning frame, and then tighten the four positioning screws so that the bottom ends of the four positioning screws are inserted into the four auxiliary support plates. 3) Insert the entire left end of the corrugated steel frame into the circular groove on the centrifugal casting shell, and then make the right end of the corrugated steel frame contact with the frame support block. 4) Slide the annular baffle b onto the two arc-shaped positioning blocks, and then rotate the adjusting screw to make the inner wall of the skeleton support block flush with the inner wall of the centrifugally cast shell. 5) Start the dual-shaft motor, then transport the concrete to the concrete guide box. After the concrete is transported, start the drive motor so that the output shaft of the drive motor drives the circular mounting shaft to rotate half a turn. 6) After molding is complete, turn off the dual-axis motor and restart the drive motor to make the output shaft of the drive motor drive the circular mounting shaft to reset. 7) Rotate the adjusting screw to make the adjusting screw drive the frame support block to continue to move downward, ensuring that the right ends of the two L-shaped limit frames are separated from the T-shaped limit blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The four auxiliary support plates of this invention increase the contact area of ​​the support positioning frame, making the support positioning frame more stable after installation; it also makes it easier for workers to separate the four auxiliary support plates from the support positioning frame, saving space and facilitating turnover and transportation.

[0016] 2. When the dual-shaft motor is working, the centrifugal casting shell rotates automatically under the action of two drive gear rings and two drive gears, realizing the automatic centrifugal casting and forming of the concrete jacking pipe; the setting of the annular baffle a and annular baffle b plays a positioning role for the corrugated steel skeleton, so that the corrugated steel skeleton can be located at the center of the formed concrete jacking pipe, ensuring the production quality of the concrete jacking pipe.

[0017] 3. This invention facilitates the connection of the concrete conveying hose to the hose connector. The two rows of concrete guide holes divert the concrete in the concrete guide box. When the output shaft of the drive motor rotates the circular mounting shaft half a turn, the two circular guide rods slide under the gravity of the circular pressing roller and the concrete guide box, causing the circular pressing roller to contact the centrifugal casting shell and the annular baffle b, pressing the inner wall of the concrete jacking pipe and making the inner wall of the concrete jacking pipe smoother after molding. When the output shaft of the drive motor resets the circular mounting shaft, the two circular guide rods also slide under the gravity of the circular pressing roller and the concrete guide box, causing the bottom of the concrete guide box to contact the circular mounting shaft, ensuring that the bottom ends of the two circular guide rods do not contact the concrete, and the circular pressing roller also does not contact the concrete.
