Description

Technical Field

[0001] The invention relates to the technical field of solidified piles, and in particular to a solidified pile embryo extrusion molding device and a solidified pile embryo molding method. Background Art

[0002] As the speed of national infrastructure construction increases year by year, solidified piles, as a mature type of pile technology, are widely used in various engineering construction fields because of their advantages such as easy to ensure pile quality, ability to withstand large loads, and durability. Solidified piles can be made in factories or on-site according to usage requirements and construction plans.

[0003] When making a solidified pile, it is necessary to carry out the processes of feeding, pressing piles, and removing piles to complete a complete solidified pile. In the prior art, when pressing piles, unidirectional extrusion is usually used, which will result in uneven density when the solidified pile is formed, resulting in insufficient structural strength of the solidified pile, making it difficult to use it as a load-bearing pile, and the qualified rate of the product is low. At the same time, since the pressing pile and the removing pile are connected together, the next preparation can only be carried out after a solidified pile embryo is made, and the production efficiency is low. Summary of the invention

[0004] The first object of the present invention is to provide a solidified pile embryo extrusion molding device, which is used to solve the problems of low product qualification rate and low production efficiency of existing solidified pile embryo molding devices.

[0005] The second object of the present invention is to provide a method for forming a solidified pile embryo, which is implemented by using the above-mentioned solidified pile embryo extrusion forming equipment.

[0006] To achieve the first object of the present invention, the present invention provides a solidified pile embryo extrusion molding device, including an extrusion module and a demoulding module, the extrusion module includes a first casing receiving platform, the first casing receiving platform is used to place the casing, the first casing receiving platform is provided with piston assemblies on two opposite sides in the horizontal direction, each piston assembly is provided with a feeding assembly and a pile core assembly on the side away from the first casing receiving platform, the feeding assembly is used to convey materials, each pile core assembly includes a pile core, the pile core can be extended into or out of the casing, the piston assembly can be extended into or out of the casing, and the piston assembly is provided with a flow channel and a first A through hole, the pile core passes through the first through hole, the feed assembly is connected with the flow channel, and the flow channel is connected to the casing; each piston assembly is provided with a one-way valve plate on the side close to the first casing receiving platform, and the one-way valve plate prevents the material in the casing from flowing back into the flow channel; the demoulding module includes a second casing receiving platform, a solidified pile embryo receiving platform, and a push rod assembly, the second casing receiving platform is used to place the casing, the solidified pile embryo receiving platform is arranged on one side of the second casing receiving platform in the horizontal direction, the push rod assembly is arranged on the other side of the second casing receiving platform in the horizontal direction, and the push rod assembly includes a push rod, and the push rod can move into or out of the casing.

[0007] It can be seen from the above scheme that the extrusion module of the present invention improves the density uniformity of the pile embryo by extruding at both ends, thereby improving the qualified rate of the product. The feed assembly is connected to the flow channel, the structure is simple and reliable, the feeding channel is short, and the resistance is small. The single-piece valve plate can close multiple flow channels, and the flow channels are arranged in the piston assembly, the structure is simple and reliable, and the one-way valve plate can effectively check the injected material; at the same time, the equipment includes two separate stations of the extrusion module and the demoulding module, and the two modules can work at the same time, which improves the molding efficiency of the pile embryo. The pile core extends in and out from both ends, which improves the efficiency of the pile core extending in and out.

[0008] A further solution is that a second through hole is also provided on the piston assembly, and a connecting rod is provided on one side of the one-way valve plate, the connecting rod extends into the second through hole, one end of the connecting rod extending into the second through hole is connected to one end of a return spring, and the other end of the return spring is connected to an abutment block.

[0009] It can be seen from the above scheme that the one-way valve plate blocks the connection between the flow channel and the sleeve when it is not working. When the feed assembly conveys materials, the materials impact the one-way valve plate to make the flow channel communicate with the inside of the sleeve, and the materials enter the sleeve through the flow channel. When the feed assembly is not conveying materials, the one-way valve plate is reset under the elastic action of the reset spring, blocking the connection between the flow channel and the sleeve, and the materials cannot flow from the sleeve to the flow channel. The reset spring of the one-way valve plate is distributed axially in the piston module, which simplifies the structure while ensuring the reliability and stability of the structure.

[0010] A further solution is that the two pile cores, the piston assembly, the one-way valve plate and the casing are coaxially arranged, the feed assembly includes a feed box and a conveying auger, the conveying auger sleeve is arranged outside the pile core, and the conveying auger is coaxially arranged with the pile core, and the conveying auger is arranged opposite to the inlet of the feed box.

[0011] It can be seen from the above scheme that this design can ensure the stability and continuity of materials during the transportation process. Since all key components are coaxially arranged, the operation of the entire system is more coordinated and efficient. The existence of the conveying auger not only improves the material transportation efficiency, but also ensures that the material can enter the working area evenly and continuously. At the same time, the relative arrangement of the feed box and the conveying auger allows the material to smoothly enter the conveying auger from the feed box, further improving the operating efficiency of the entire system. In addition, such a design also helps to reduce energy consumption and wear, because the material encounters less resistance during transportation, and the coaxial arrangement of the conveying auger and the pile core reduces unnecessary friction and loss. At the same time, the pile core acts as the support part of the conveying auger, which is conducive to structural simplification and improving the overall structural strength.

[0012] A further solution is that a bidirectional hydraulic cylinder is connected between the two piston assemblies, and the bidirectional hydraulic cylinder drives the piston assemblies to move into or out of the sleeve at the same time.

[0013] It can be seen from the above scheme that the two piston assemblies are connected by a bidirectional hydraulic cylinder, which improves the uniformity of the extrusion force at both ends and is conducive to simplifying the extrusion mechanism and improving the structural strength of the extrusion mechanism.

[0014] A further solution is that a push rod head is provided on one side of the push rod close to the second casing receiving platform, and the diameter of the push rod head is larger than the inner diameter of the solidified pile embryo in the casing.

[0015] It can be seen from the above scheme that the arrangement of the push rod head prevents the push rod from damaging the pile embryo.

[0016] A further solution is that a protrusion is provided on a side of one of the two pile cores close to the casing, and a groove matching the protrusion is provided on a side of the other of the two pile cores close to the casing.

[0017] It can be seen from the above scheme that the arrangement of the groove and the protrusion facilitates the alignment of the two pile cores and the connection stability.

[0018] A further solution is that the extrusion module also includes a first guide rail, on which a first sleeve receiving platform and two piston slides are provided, the piston assembly is provided on the piston slide, and the first sleeve receiving platform and the two piston slides can move along the first guide rail; the demolding module also includes a second guide rail, on which a second sleeve receiving platform, a solidified pile embryo receiving platform and a push rod slide are provided, the push rod assembly is provided on the push rod slide, and the second sleeve receiving platform, the solidified pile embryo receiving platform and the push rod slide can move along the second guide rail.

[0019] It can be seen from the above scheme that the setting of the guide rail structure enables the equipment to adapt to the production of pile blanks of different sizes and lengths.

[0020] A further solution is that both piston slides are provided with a support rod and a first bracket, a feed assembly is installed on the support rod, the pile core passes through the first bracket, and a feed drive component and a pile core adjustment drive component are installed on the first bracket, and one end of the two pile cores close to the pile core adjustment drive component is provided with a pile core external thread; a push rod drive component is provided on the push rod slide, and a push rod drive component is provided on one end of the push rod close to the push rod drive component.

[0021] It can be seen from the above scheme that the above arrangement is conducive to simplifying the driving mechanism for moving the pile core and reducing the friction between the pile core and the spiral extrusion mechanism.

[0022] A further solution is that a hanging point is arranged outside the casing, and the hanging point is used to suspend the casing; a liquid discharge port is also arranged on the casing.

[0023] It can be seen from the above scheme that the hanging point is used to suspend the casing to facilitate the movement of the casing, and the drainage port is provided to facilitate the discharge of excess liquid.

[0024] In order to achieve the second purpose of the present invention, the present invention provides a molding method for solidified pile embryos, which is implemented by using a solidified pile embryo extrusion molding device described in any of the above schemes, and the molding method comprises the following steps: S1: placing a sleeve on a first sleeve receiving platform of an extrusion module, the pile core extends into the sleeve to a predetermined position from both ends, and the piston assembly extends into both ends of the sleeve; S2: the feed assembly inputs the material and injects it into the sleeve through the flow channel of the piston assembly; S3: the piston assemblies on both sides of the sleeve continue to move into the sleeve and approach each other to squeeze the material in the sleeve, and the excess liquid in the material is discharged through the discharge port of the sleeve; S4: repeating the process of step S2 and step S3 until a predetermined number of repetitions is reached; S5: withdrawing the piston assembly and the pile core from the sleeve, and moving the sleeve to a second sleeve receiving platform; S6: the push rod extends into the sleeve until the solidified pile embryo in the sleeve is pushed onto the solidified pile embryo receiving platform to obtain a solidified pile embryo.

[0038] See also Figure 1 The solidified pile embryo extrusion molding equipment provided in this embodiment includes an extrusion module 1 and a demoulding module 2.

[0039] See also Figures 2 to 9The extrusion module 1 includes a first guide rail 17, on which a first sleeve receiving platform 11 and two piston slides 124 are arranged. The first sleeve receiving platform 11 and the two piston slides 124 can move along the first guide rail 17. The two piston slides 124 are arranged on opposite sides of the first sleeve receiving platform 11 along the first guide rail 17. The first sleeve receiving platform 11 is used to place the sleeve 3. Each piston slide 124 is provided with a piston assembly 12, a feed assembly, a pile core assembly and a first bracket 1241. When the sleeve 3 is placed on the first sleeve receiving platform 11, the piston assembly 12 can move into or out of the sleeve 3, the feed assembly is arranged on the side of the piston assembly 12 away from the sleeve 3, and the first bracket 1241 is arranged on the side of the feed assembly away from the piston assembly 12. The column core assembly includes a column core 161, and the column core 161 can pass through the first bracket 1241, the feed assembly, and the piston assembly to move into or out of the sleeve 3.

[0040] The piston assembly 12 is provided with a flow channel 121, a first through hole 122 and a second through hole 123. There are multiple flow channels 121, and the multiple flow channels 121 are evenly arranged on the piston assembly 12. One side of the flow channel 121 is connected to the feed assembly, and the other side of the flow channel 121 can be connected to the sleeve 3. The pile core 161 passes through the first through hole 122 and can extend into the sleeve 3.

[0041] The outer diameter of the side of the piston assembly 12 extending into the sleeve 3 is smaller than the inner diameter of the sleeve 3, and the outer diameter of the side of the piston assembly 12 away from the sleeve 3 is larger than the inner diameter of the sleeve 3. A one-way valve plate 13 is provided on the side of the piston assembly 12 close to and capable of extending into the sleeve 3, and a connecting rod 131 is provided on one side of the one-way valve plate 13, and one end of the connecting rod 131 extends into the second through hole 123 of the piston assembly 12. One end of the connecting rod 131 extending into the second through hole 123 is connected to one end of a return spring 132, and the other end of the return spring 132 is connected to an abutment block 133. One side of the abutment block abuts against the feed assembly to achieve fixation. The one-way valve plate 13 is provided to prevent the material in the sleeve 3 from flowing back into the flow channel 121. Specifically, the one-way valve plate 13 blocks the connection between the flow channel 121 and the sleeve 3 when it is not in operation. When the feeding component conveys material, the material impacts the one-way valve plate 13 to connect the flow channel 121 with the inside of the sleeve 3, and the material enters the sleeve 3 through the flow channel 121. When the feeding component is not conveying material, the one-way valve plate 13 is reset under the elastic action of the reset spring 132, thereby blocking the connection between the flow channel 121 and the sleeve 3, and the material cannot flow from the sleeve 3 to the flow channel 121.

[0042] The feed assembly includes a feed box 151, a conveying auger 152 and a feed drive component. The conveying auger 152 is sleeved outside the pile core 161, and the conveying auger 152, the pile core 161, the piston assembly 12, the one-way valve plate 13 and the sleeve 3 are coaxially arranged. The inlet of the feed box 151 is arranged opposite to the conveying auger 152. The feed box 151 is fixed to the piston slide 124 through a support rod 155, and the feed box 12 is connected to the piston assembly 12 through a connecting flange 154. The feed drive assembly is arranged on the first bracket 1241, and the feed drive assembly includes a feed worm wheel 1531, a feed worm 1532 and a first motor 1533. The first motor 1533 and the feed worm 1532 are coaxially arranged. The feed worm wheel 1531 is connected to the conveying auger 152. The first motor 1533 drives the feed worm 1532 to rotate. The feed worm 1532 is meshed with the feed worm wheel 1531, driving the feed worm wheel 1531 and the conveying auger 152 to rotate, thereby realizing the transportation of materials.

[0043] The pile core assembly also includes a pile core driving component, which is arranged on the first bracket 1241. The pile core driving component includes a pile core adjusting worm wheel 1621, a pile core adjusting worm 1622 and a second motor 1623. The second motor 1623 is coaxially connected with the pile core adjusting worm 1622. The pile core 161 is provided with a pile core external thread 1613. The pile core 161 passes through the pile core adjusting worm wheel 1621 and meshes with the pile core adjusting worm wheel 1621. The second motor 1623 drives the pile core adjusting worm 1622 to rotate. The pile core adjusting worm 1622 meshes with the pile core adjusting worm wheel 1621, driving the pile core 161 and the pile core adjusting worm wheel 1621 to generate displacement, so that the pile core 161 moves into or out of the casing 3. The above structure simplifies the structure, is easy to operate and has good stability on the basis of saving space to the greatest extent. The outer peripheral surface of the pile core 161 is provided with a pile core external thread, which is beneficial to simplifying the driving mechanism for moving the pile core 161 and reducing the friction between the pile core 161 and the conveying auger 152 .

[0044] See also Figure 3 and Figure 5 The pile cores 161 on the right and left sides are respectively the first pile core 1611 and the second pile core 1612. A convex block is provided on the side of the first pile core 1611 close to the second pile core 1612, and a groove is provided on the side of the second pile core 1612 close to the first pile core 1611. The convex block matches the groove, so that the pile cores 161 on both sides can be connected to form a complete pile core 161 in the casing 3.

[0045] See also Figure 2 and Figure 4The pile core 161 is provided with a first anti-rotation groove at one end close to the pile core adjustment driving component, and a detachably mounted first anti-rotation pin 181 is provided on the first bracket 1241. When the first anti-rotation pin 181 is inserted into the first anti-rotation groove, the pile core 161 cannot rotate or move. The provision of the first anti-rotation pin 181 makes the extrusion module 1 safer and reduces potential safety hazards.

[0046] See also Figure 2 A bidirectional hydraulic cylinder 14 is connected between the two piston assemblies 12, and the bidirectional hydraulic cylinder 14 drives the piston assembly 1 to move into or out of the sleeve 3 at the same time.

The second casing receiving platform 22 is used to place the casing 3 with solidified pile embryo 4 formed inside after being extruded by the extrusion module 1. The solidified pile embryo receiving platform 21 is arranged on one side of the second casing receiving platform 22, and the push rod slide 231 is arranged on the other side opposite to the second casing receiving platform 21. The solidified pile embryo receiving platform 21 is provided with a receiving groove 211 for receiving the solidified pile embryo 4 pushed out.

[0048] The push rod assembly includes a push rod 232 and a push rod driving component. A push rod support 2311 and a second bracket 2312 are provided on the push rod slide 231. The push rod 232 passes through the push rod support 2311 and the second bracket 2312, and the push rod support 2311 and the second bracket 2312 play a certain supporting role for the push rod 232. The push rod driving component is provided on the second bracket 2312.

[0049] When the second casing receiving platform 22 is placed with the casing 3, the push rod driving component can drive the push rod 232 to move into or out of the casing 3. A push rod head 2321 is provided on one side of the push rod 232 close to the casing 3. The diameter of the push rod head 2321 is smaller than the inner diameter of the casing 3 and larger than the inner diameter of the cured pile embryo 4 in the casing 3 (i.e., the outer diameter of the pile core 161). Preferably, the diameter of the push rod head 2321 is equal to the outer diameter of the cured pile embryo 4.

[0050] The push rod 232 is provided with a push rod external thread on one side away from the push rod head 2321. The push rod driving component includes a push rod adjusting worm wheel 2331, a push rod adjusting worm 2332 and a third motor 2333. The third motor 2333 is coaxially arranged with the push rod adjusting worm 2332. The push rod 232 passes through the push rod adjusting worm wheel 2331 and meshes with the push rod adjusting worm wheel 2331. The third motor 2333 drives the push rod adjusting worm 2332 to rotate. The push rod adjusting worm 2332 meshes with the push rod adjusting worm wheel 2331, driving the push rod 232 and the push rod adjusting worm wheel 2331 to generate displacement, so that the push rod 232 moves into or out of the sleeve 3.

[0051] See also Fig.10 The push rod 232 is provided with a second anti-rotation groove at one end close to the push rod driving component, and a detachably mounted second anti-rotation pin 251 is provided on the second bracket 2312. When the second anti-rotation pin 251 is inserted into the second anti-rotation groove, the push rod 232 cannot rotate. The provision of the second anti-rotation pin 251 makes the demoulding module 2 safer and reduces potential safety hazards.

[0052] The second guide rail 24 is also provided with a positioning pin and a limiting pin. The positioning pin is used to position the solidified pile embryo slide 21 , and the limiting pin is used to limit the second casing receiving platform 22 .

[0053] See also Figure 3 and Figure 5 The casing 3 of the solidified pile embryo extrusion molding equipment of this embodiment is provided with a hanging point 31, which is used to suspend the casing 3 to facilitate the movement of the casing 3. The casing 3 is also provided with a drainage port. In addition to the filter screen 321, the drainage port is connected to a drainage pipe. Preferably, the drainage port is arranged at the top of the casing 3, the sediment sinks, and the liquid is located in the upper layer, reducing the probability of clogging of the drainage port.

[0054] The solidified pile embryo molding method provided in this embodiment is implemented by using the solidified pile embryo extrusion molding equipment, and the molding method comprises the following steps:

[0055] S1: Use a crane to place the casing 3 on the first casing receiving platform 11 of the extrusion module 1, the pile core 161 extends from both ends into the casing 3 to a predetermined position, and the bidirectional hydraulic cylinder 14 drives the piston assembly 12 to extend into the same distance at both ends of the casing 3;

[0056] S2: the material input by the feed component is injected into the casing through the flow channel of the piston component. In this embodiment, the material is a slurry mixed with sludge, biological consolidation material, inorganic consolidation material, and organic consolidation material;

[0057] S3: Under the same driving force of the bidirectional hydraulic cylinder 14, the piston assemblies 12 on both sides of the casing 3 continue to move into the casing 3 and approach each other, thereby squeezing the material in the casing 3, and the excess liquid in the material is discharged through the discharge port of the casing 3;

[0058] S4: repeating the process of step S2 and step S3 until a predetermined number of repetitions is reached. The specific number of repetitions may be one, two, three or even more times. The increase in the number of repetitions is conducive to improving the density uniformity and structural strength of the pile embryo. It should be noted that the extrusion driving force of each subsequent time is greater than the extrusion driving force of the previous time;

[0059] S5: withdraw the piston assembly 12 and the pile core 161 from the casing 3, and use a crane to move the casing 3 to the second casing receiving platform 24;

[0060] S6: The push rod 232 extends into the casing 3 until the solidified pile embryo 4 in the casing 3 is pushed onto the solidified pile embryo receiving platform 21 to obtain the solidified pile embryo 4.

[0061] The solidified pile embryo 4 produced by the solidified pile embryo extrusion molding equipment of this embodiment is a hollow cylindrical pile embryo.

[0062] The extrusion module 1 of this embodiment improves the uniformity of the density of the solidified pile embryo 4 by extrusion at both ends, thereby improving the qualified rate of the product. The feed assembly is connected to the flow channel 121, the structure is simple and reliable, the feeding channel is short, and the resistance is small.
