Technical Field

[0001] The utility model relates to the field of steel socket pipe production, in particular to a mould for producing reinforced concrete steel socket pipes. Background Art

[0002] Reinforced concrete steel socket pipe combines the strength of reinforced concrete with the ease of connection of a steel socket. Primarily made of cement, rebar, sand, and gravel, it is formed using a specialized process and features a steel socket and a spigot at each end. This design allows the pipe to be inserted through the spigot into the socket during connection, sealing the joint and enhancing joint strength and overall system stability.

[0003] In order to produce reinforced concrete steel socket pipes, a reinforced concrete steel socket pipe production mold is needed.

[0004] Currently, reinforced concrete steel socket pipes are produced by injecting concrete into the inside of a pipe mold, waiting for the concrete to solidify, and finally demolding. Directly injecting concrete into the mold will produce more bubbles inside the mold, affecting the connection strength of the steel socket pipe. Currently, a vibration device is usually added to the outside of the mold to vibrate the mold to eliminate internal gaps. However, in actual use, steel socket pipes are generally larger, and higher requirements are placed on the vibration capacity and load-bearing capacity of the vibration device. At the same time, the cost is also high. Therefore, a mold for the production of reinforced concrete steel socket pipes is proposed to solve the above problems. Utility Model Content

[0032] Reference Figure 1-Figure 2 The right end of the rotating shaft 7 is fixedly connected to a driving gear 9, and the bottom end of the driving gear 9 is engaged with a passive gear 10. The rotation of the driving gear 9 can drive the passive gear 10 to rotate. The interior of the passive gear 10 is fixedly connected to a rotating column 11 that plays a connecting and supporting role. The left end of the rotating column 11 is rotatably connected to the right end of the rotating base 6. The outer periphery of the rotating column 11 is fixedly connected to a transmission wheel 12. There are two groups of transmission wheels 12. The two groups of transmission wheels 12 are symmetrically arranged front and back. The outer periphery of the two groups of transmission wheels 12 are connected by a belt 13. When the transmission wheel 12 on one side rotates, the transmission wheel 12 on the other side will be driven to rotate at the same speed and in the same direction through the belt 13.

[0033] Reference Figure 3-Figure 4The mold assembly includes an outer mold 14. The bottom of the outer mold 14 contacts the top surface of the rotating roller 8. The rotation of the rotating roller 8 can drive the outer mold 14 assembly to rotate through friction. The inner core 15 is detachably connected to the inner part of the outer mold 14. The top of the outer mold 14 is provided with a grouting hole 16. Concrete can be poured into the interior through the grouting hole 16. The inner wall of the grouting hole 16 is provided with a card slot 17. The card slot 17 is provided in four groups and is evenly distributed in an annular shape on the side wall of the grouting hole 16. A card block 18 is clamped inside the card slot 17. The outer periphery of the block 18 is slidably connected with a sealing round block 19, and the card groove 17 and the block 18 fix the sealing round block 19. The outer periphery of the sealing round block 19 is slidably connected to the inside of the grouting hole 16 to seal the mold. The top of the sealing round block 19 is fixedly connected with a threaded seat 20. The inner thread of the threaded seat 20 is connected with a threaded column 21. When the threaded column 21 is rotated, the threaded column 21 can slide up and down the inner wall of the threaded seat 20. The outer periphery of the threaded column 21 is provided with a slide groove 22. The slide groove 22 is provided with four groups, and the annular average Distributed on the outer periphery of the threaded column 21, the slide 23 is slidably connected inside the slide 22, and a rotating round block 24 is fixedly connected to the outside of the slide 23. The slide 23 and the slide 22 enable the rotating round block 24 to rotate in the same direction as the threaded column 21. The top of the rotating round block 24 is rotatably connected to the top inner wall of the sealing round block 19. The bottom of the rotating round block 24 is hinged with a connecting rod 25.

The bottom of the block 18 is slidably connected to a slide rail 26, which limits the block 18 to slide only along the outer wall of the slide rail 26. The bottom of the slide rail 26 is fixedly connected to the inner wall of the bottom end of the sealing round block 19. The outer periphery of the threaded column 21 is slidably connected to a protective sleeve 27 to prevent the threaded column 21 from solidifying with the concrete and making it impossible to demold. When the protective sleeve 27 is not in use, the top can be sealed with a cover to prevent concrete from entering the interior during grouting. The bottom of the protective sleeve 27 is fixedly connected to the top of the inner core 15.

[0034] Working principle: When you want to make the concrete inside the mold evenly distributed and solidified, turn on the rotating motor 3, and the rear end output shaft of the rotating motor 3 drives the worm 4 to rotate. The worm 4 drives the top worm gear 5 to rotate slowly and provides a large torque. The worm gear 5 drives the front rotating shaft 7 to rotate, and the front rotating shaft 7 drives the front driving gear 9 to rotate. The front driving gear 9 drives the front passive gear 10 to rotate. The front passive gear 10 drives the front transmission wheel 12 to rotate. The front transmission wheel 12 drives the rear transmission wheel 12 to rotate through the belt 13. The rear transmission wheel 12 drives the rear passive gear 10 to rotate. The rear passive gear 10 drives the rear driving gear 9 to rotate. The rear driving gear 9 drives the rear rotating shaft 7 to rotate. The front and rear rotating shafts 7 rotate at the same speed and in the same direction, driving the front and rear rotating rollers 8 to rotate at the same speed and in the same direction, thereby driving the mold assembly to rotate slowly, causing the concrete inside the mold assembly to rotate, eliminating the gaps between the internal concrete, and ensuring product quality. When you want to close the grouting hole 16, after grouting is completed, slide the sealing block 19 into the grouting hole 16, so that the threaded column 21 slides into the protective sleeve 27, rotate the threaded column 21, and the threaded column 21 moves downward. At the same time, the threaded column 21 drives the rotating block 24 to rotate through the slider 23 and the slide groove 22. The rotating block 24 drives the block 18 to move outward along the slide rail 26 through the connecting rod 25 and is stuck into the inside of the slot 17. At the same time, the threaded column 21 moves downward to resist the bottom of the protective sleeve 27, pushing the block 18 upward to resist the slot 17, thereby improving the sealing of the grouting hole 16 and ensuring that the internal concrete will not spill out when the mold assembly is rotated.
