Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a high-efficiency and energy-saving pipe pile processing rapid demoulding device and method thereof. Background Art

[0002] Pipe piles are a kind of hollow pile foundation material, mainly used for the foundation parts of buildings, bridges, docks and other projects. Pipe piles are installed in the foundation by driving or vibrating and sinking. They are used to bear the load of the building and transfer it to the foundation to ensure the stability and safety of the building. Pipe piles are mainly made by pouring concrete into the lower mold, then closing the upper mold and the lower mold, forming a tube by centrifugal rotation, and finally finalizing it through high-temperature curing.

[0003] The existing mold clamping method is a bolt-fixed connection, but since the mold needs to be reused many times, the bolts need to be tightened and loosened many times, which will cause the thread of the bolts to wear, easily leading to thread stripping of the bolts and nuts, resulting in mold clamping failure, or loosening after mold clamping. In addition, the bolts need to be loosened one by one during the mold removal process, which is not convenient for quick disassembly and has low efficiency. Summary of the invention

[0016] A high-efficiency and energy-saving method for rapid demoulding of pipe piles:

[0017] Step 1: Install the steel ring on the base and place it in the lower mold;

[0018] Step 2: pouring concrete into the lower mold through the pouring device, and the concrete will not overflow from the lower mold due to the blocking of the polymer plate;

[0019] Step 3: Lift the upper die onto the lower die through the lifting device, and position the upper die vertically through the positioning ring;

[0020] Step 4: The upper die and the lower die are tightly fitted by rotating the extrusion block to complete the clamping of the lower die and the upper die. The clamping block restricts the connecting rod to ensure that the extrusion block can stably clamp the upper die and the lower die.

[0023] As described above, the beneficial effects of the high-efficiency and energy-saving pipe pile processing rapid demoulding device and method thereof in the present invention are as follows:

[0024] The rotating block rotates downward through the interference of the vertical groove of the limit groove block, and the swing block drives the extrusion block to rotate downward to a vertical state. At this time, the extrusion block will contact the outer surfaces of both sides of the upper mold and push the upper mold, so that the upper mold moves downward again and fits and clamps with the upper surfaces of both sides of the lower mold, thereby achieving the effect of rapid mold clamping and fixing. Compared with the existing mold clamping and fixing by bolts, a lot of time is saved, the difficulty of operation and labor intensity are reduced, and the problem of being unable to effectively clamp the lower mold and the upper mold after the conventional bolts are repeatedly tightened and loosened and the thread slips, is avoided, and the stability of the clamping and fixing of the lower mold and the upper mold is improved;

[0025] The connecting rod can limit the pull rod through the connecting block, and the assembly and disassembly components can be locked by the pull rod and the sliding rod, so that multiple extrusion blocks can always contact and fit the outer surfaces of both sides of the upper mold, always maintaining the effect of tightly clamping the upper mold, which can effectively prevent the assembly and disassembly components from loosening and improve the tightness and stability of the upper and lower molds.

[0026] The spring 4 will make the positioning ring move upward within a short distance inside the retraction groove, and the positioning ring will move upward within a short distance inside the lower pressure groove by pushing the lower pressure ring, and the lower pressure ring will drive the upper mold to move upward, so that the upper mold and the lower mold can be quickly removed, thereby avoiding the problem of high difficulty in demolding caused by the tight clamping of the existing upper mold and the lower mold, and also preventing the upper mold and the lower mold from being damaged by demolding with a crowbar during demolding;

[0027] The movement of the polymer plate will push the concrete accumulated on the upper surfaces on both sides of the lower mold, allowing the accumulated concrete to enter the interior of the lower mold. The accumulated concrete can be pushed over a large area in a short time, which can effectively shorten the pouring cycle of each pipe pile. Compared with the manual shoveling method, it can avoid concrete residue on the upper surfaces on both sides of the lower mold, reducing the residual concrete affecting the tightness after mold closing.

Two movable grooves 47 corresponding to the position of the middle lifting groove 44 are opened on both sides of the lower mold 1. A through hole connected to the middle lifting groove 44 is opened in the middle of the groove wall of the movable groove 47. A clamping block 412 is slidably connected inside the through hole.

[0052] like Figure 2 , Figure 3 , Figure 8 and Fig.12 As shown, ejection assemblies for ejecting the upper mold 2 and the lower mold 1 when they are disassembled are provided on both ends of the base 11 and the upper mold 2, and the ejection assembly includes a lower pressure ring 61 fixedly connected to the two end ends of the upper mold 2, and the tops of the two bases 11 are provided with lower pressure grooves 62, and the shape of the lower pressure ring 61 is the same as that of the lower pressure groove 62, so that the lower pressure ring 61 can form a full circle with the base 11 after being embedded in the lower pressure groove 62, and the interior of the two bases 11 is provided with a retraction groove 63, and the top of the retraction groove 63 is connected to the lower pressure groove 62, and a plurality of springs four 64 are fixedly connected to the interior of the retraction groove 63, and a positioning ring 65 is fixedly connected to the top of the spring four 64, and the bottom of the positioning ring 65 slides inside the retraction groove 63, and the outer ring size of the positioning ring 65 is adapted to the inner ring size of the lower pressure ring 61.

[0053] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0054] The initial state is:

[0055] The lifting rod 33 is located at the highest position of the through-tube 31. The lifting rod 33 makes the rotating block 35 at the highest position through the connecting frame 34. At this time, the rotating block 35 is in contact with the flat groove surface of the limiting groove block 32. At this time, the torsion spring 351 is not deformed and tightened. At this time, the rotating block 35 is in a vertical state. The sliding shell 38 makes the pull rod 42 at the highest position through the sliding rod 41. The pull rod 42 makes the connecting rod 45 at the highest position inside the lifting groove 44 through the connecting block 46. The bottom of the connecting rod 45 is in conflict with the inclined surface of the block 412 close to the lifting groove 44. At this time, the block 412 is squeezed by the extrusion triangle block 410 through its inclined surface close to the movable groove 47. The extrusion triangle block 410 makes the top spring 2 48 in a slightly stretched state and the bottom spring 2 48 in a slightly compressed state through the movable block 49.

[0056] The working status is:

[0057] The staff places the lower mold 1 on the workbench, and then installs and fixes the steel mesh cage in the lower mold 1 through the base 11, wherein the steel mesh cage is a tubular mesh cage formed by welding iron wire and steel ring by an existing rolling welding machine. The staff then uses the existing concrete discharge device to evenly pour the concrete into the lower mold 1. At this time, if there is excess concrete accumulated on the upper surfaces on both sides of the lower mold 1, it will be blocked by the polymer plate 53 to prevent the concrete from falling outside the lower mold 1, thereby reducing the waste of concrete.

[0058] The ejector assembly assists the upper mold 2 and the lower mold 1 in closing the mold:

[0059] When the upper die 2 moves downward, the lower pressure ring 61 is driven to contact with the positioning ring 65. When the upper die 2 moves downward, the lower pressure ring 61 is driven to contact with the positioning ring 65. When the upper die 2 moves downward, the positioning ring 65 is squeezed by the arc surface of the positioning ring 65. At this time, the lower pressure ring 61 is embedded in the lower pressure groove 62 to achieve limiting, so that the positioning ring 65 moves downward inside the retraction groove 63. The downward movement of the positioning ring 65 compresses the spring four 64, but does not completely compress the spring four 64 to the shortest state. Under the elastic action of the spring four 64, the positioning ring 65 makes the lower pressure ring 61 not completely overlap with the lower pressure groove 62. At this time, the lower pressure ring 61 makes the upper die 2 not completely overlap with the lower die 1. At this time, a gap is left between the upper die 2 and the lower die 1.

[0060] The locking assembly enables the assembly and disassembly assembly to quickly fix the upper mold 2 and the lower mold 1 together:

[0061] At this time, the staff can pull the connecting block 46 to drive the connecting rod 45 to move downward in the lifting groove 44, and drive the pull rod 42 to move downward. During the downward movement, the pull rod 42 will also drive the sliding rod 41 to move downward synchronously, and the sliding rod 41 will drive the sliding shell 38 to move vertically downward. Since the pull rod 42 is arc-shaped, the pull rod 42 will rotate accordingly around the connection point between the two when driving the sliding rod 41 to move downward, and will also drive the sliding rod 41 to slide horizontally in the sliding shell 38, so as to ensure the vertical downward movement of the sliding shell 38. When the sliding shell 38 moves downward, the spring 39 will be stretched. At the same time, the sliding shell 38 will also drive the lifting rod 33 to move downward inside the through-tube 31, and the lifting rod 33 drives the connecting frame 34 to move downward, and the connecting frame 34 will drive the rotating block 35 to move downward synchronously, and the rotating block 35 will resist and fit in the limit groove block 32. The cam 35 is pressed against the top of the mould 34 and the cam 36 is pressed against the top of the mould 34. The cam 36 is pressed against the top of the mould 34 and the cam 36 is pressed against the top of the mould 34. The cam 36 is pressed against the top of the mould 34 and the cam 36 is pressed against the top of the mould 34.

[0062] Because there is a gap between the upper mold 2 and the lower mold 1, when the upper mold 2 and the lower mold 1 are closed by the assembly and disassembly components, the upper mold 2 will move downward for a distance again, and the upper mold 2 will push the positioning ring 65 downward again through the lower pressure ring 61, so that the positioning ring 65 moves downward and compresses the spring four 64 again. At this time, the positioning ring 65 completely enters the interior of the retraction groove 63, and the lower pressure ring 61 is completely embedded in the interior of the lower pressure groove 62. At this time, the lower pressure ring 61 will be combined with the base 11 to form a complete circle, which is convenient for subsequent centrifugal operations.

[0063] The locking assembly locks and fixes the assembly and disassembly assembly:

[0064] During the downward movement of the connecting block 46, the connecting block 46 will drive the pull rod 42 to move downward stably in the sliding hole of the stabilizing block 43, and the connecting block 46 will also drive the connecting rod 45 to move downward in the lifting groove 44. When the connecting rod 45 moves downward, it will contact the inclined surface of the block 412, so that the block 412 moves toward the side close to the movable groove 47 in the through hole. At this time, the inclined surface of the block 412 close to the movable groove 47 will squeeze the inclined surface of the triangular block 410, pushing the triangular block 410 to move downward inside the movable groove 47, squeezing the triangular block 410. The corner block 410 will drive the movable block 49 to move downward for a distance inside the movable groove 47, and the movable block 49 will stretch the top spring 2 48 again and compress the bottom spring 2 48. When the connecting rod 45 moves to the lowest position of the lifting groove 44, the top of the connecting rod 45 is lower than the lower surface of the block 412. Under the elastic reset action of the spring 2 48, the movable block 49 moves upward inside the movable groove 47. The movable block 49 will drive the extrusion triangle block 410 to move upward, and the extrusion triangle block 410 pushes the block through its inclined surface. 412, so that the card block 412 moves in the perforation toward the side close to the lifting slot 44, at this time, the lower surface of the card block 412 will conflict with the upper surface of the connecting rod 45, that is, at this time, the movable block 49 moves to the middle position of the movable slot 47, and the two springs 48 are not stretched or compressed, and then at this time, the dial plate 411 will be located at the position of the card slot 413, and the magnetic block in the card slot 413 will magnetically attract the dial plate 411 after half a year, so that the dial plate 411 can shrink and move toward the inside of the card slot 413, and the card slot 413 will limit the dial plate 411 at this position. The position of the external clamping block 412 is limited, so the connecting rod 45 can also be restricted, so that the connecting rod 45 cannot move upward inside the lifting groove 44. The connecting rod 45 can limit the pull rod 42 through the connecting block 46, and further lock the assembly and disassembly components through the pull rod 42 and the sliding rod 41, so that the multiple extrusion blocks 37 can always contact and fit the outer surfaces on both sides of the upper mold 2, always maintain the effect of tightly clamping the upper mold 2, and can effectively prevent the assembly and disassembly components from loosening, thereby improving the tightness and stability of the upper mold 2 and the lower mold 1.

[0065] The cleaning assembly pushes the excess concrete into the lower mold 1:

[0066] During the downward movement of the upper mold 2 and the closing mold with the lower mold 1, the inclined surfaces on both sides of the upper mold 2 will meet the top inclined surface of the polymer plate 53 during the downward movement, and then push the polymer plate 53, so that the polymer plate 53 moves toward the inner side of the lower mold 1 through the T-shaped block inside the slide groove 51, and the spring three 52 will be stretched during the movement of the polymer plate 53. At this time, the movement of the polymer plate 53 will push the concrete accumulated on the upper surfaces on both sides of the lower mold 1, so that the accumulated concrete enters the lower mold 1. The accumulated concrete can be pushed over a large area in a short time, which can effectively shorten the casting cycle of each pipe pile. Compared with the manual shoveling method, it can avoid the concrete remaining on the upper surface of both sides of the lower mold 1, and further prevent the residual concrete when the lower mold 1 and the upper mold 2 are closed from affecting the tightness after closing the mold.

[0067] In addition, after the upper mold 2 and the lower mold 1 are molded together, the arc surface of the polymer plate 53 will overlap with the interior of the upper mold 2, so that the upper mold 2 and the lower mold 1 form a full circle after the mold is molded together.

[0068] Pipe pile forming:

[0069] The lower mold 1 and the upper mold 2 are hoisted as a whole onto an existing centrifugal device through a hoisting device, so that the lower mold 1 and the upper mold 2 rotate on the centrifugal device, and the concrete inside the lower mold 1 and the upper mold 2 is evenly attached to the steel ring by centrifugation, so that the concrete forms a tube in the lower mold 1 and the upper mold 2, and the concrete in the lower mold 1 and the upper mold 2 is dried and shaped by steam drying. The above is a device and a production method used in the existing pipe pile production process.

[0070] The upper mold 2 and the lower mold 1 can be quickly disassembled by assembling and disassembling components:

[0071] After the concrete is set, the staff can first pull the dial plate 411 away from the card slot 413 to make the dial plate 411 disengage from the card slot 413, and then press the dial plate 411 to drive the extrusion triangle block 410 to move downward, and the extrusion triangle block 410 drives the movable block 49 to move downward inside the movable groove 47. At this time, the movable block 49 will compress the spring 2 48 at the bottom and stretch the spring 2 48 at the top. In the process of the downward movement of the extrusion triangle block 410, the card block 412 will be moved closer to the movable groove 4 in the perforated inner part by magnetic attraction. 7 moves on one side, at this time, the block 412 cannot limit the connecting rod 45, and under the elastic reset action of the spring 1 39, the spring 1 39 will drive the sliding shell 38 to move upward, the sliding shell 38 drives the sliding rod 41 to move upward, the sliding rod 41 drives the pull rod 42 to move upward in the sliding hole of the stabilizing block 43, and the pull rod 42 drives the connecting rod 45 to move upward inside the lifting groove 44 through the connecting block 46. During the upward movement of the sliding shell 38, the lifting rod 33 is driven to move upward inside the through tube 31, and the lifting rod 33 drives the connecting frame 34 to move upward. After the connecting frame 34 drives the rotating block 35 to move upward, the rotating block 35 is no longer restricted by the vertical groove of the limit groove block 32. Under the elastic reset action of the torsion spring 351, the rotating block 35 rotates inside the connecting frame 34, and the rotating block 35 will fit with the flat groove of the limit groove block 32 again. During the rotation of the rotating block 35, the extrusion block 37 is driven by the swing block 36 to no longer contact and squeeze the upper surfaces of both sides of the upper mold 2. At the same time, under the elastic reset action of the spring four 64, the spring four 64 will make the positioning ring 65 move upward for a short distance inside the retraction groove 63. The positioning ring 65 will move upward within a short distance in the lower pressure groove 62 by pushing the lower pressure ring 61, and the lower pressure ring 61 will drive the upper mold 2 to move upward, so that the upper mold 2 and the lower mold 1 can be quickly removed, thereby avoiding the problem of high difficulty in demolding caused by the tight mold closing of the existing upper mold 2 and the lower mold 1, thereby achieving the effect of rapid demolding. Compared with the existing manual loosening of the bolts one by one, the demolding time can be reduced, the labor cost of manual operation can be reduced, and the damage of the upper mold 2 and the lower mold 1 caused by demolding with a crowbar during the demolding process can be prevented.

[0072] Embodiment 2: A high-efficiency and energy-saving method for quickly removing molds from pipe piles:

[0073] Step 1: Install the steel ring on the base 11 and place the steel ring in the lower mold 1;

[0074] Step 2: pouring concrete into the lower mold 1 through the pouring device, and the concrete will not overflow from the lower mold 1 to the outside of the lower mold 1 due to the blocking of the polymer plate 53;

[0075] Step 3: hoist the upper die 2 onto the lower die 1 by means of a hoisting device, and position the upper die 2 vertically by means of a positioning ring 65;

[0076] Step 4: The upper mold 2 and the lower mold 1 are tightly fitted together by rotating the extrusion block 37, and the lower mold 1 and the upper mold 2 are clamped together. The clamping block 412 restricts the connecting rod 45, so that the extrusion block 37 can stably clamp the upper mold 2 and the lower mold 1.

[0077] Step 5: During the closing process of the upper mold 2 and the lower mold 1, the polymer plate 53 is pushed so that the polymer plate 53 pushes the concrete accumulated on both sides of the lower mold 1 into the lower mold 1;

[0078] Step six: Pull the paddle 411 to disengage it from the engagement relationship with the engagement slot 413, so that the extrusion triangle block 410 contacts the block 412 to restrict the connecting rod 45. The extrusion block 37 releases the fixation on the upper mold 2 at this time, and the positioning ring 65 pops up upward to achieve rapid demolding of the upper mold 2.

[0079] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
