Description

Technical Field

[0001] The present invention relates to the technical field of precast pile production equipment, in particular to precast pile production casting equipment. Background Art

[0002] Precast piles refer to piles that are prefabricated on-site at or near the piling site. Shorter piles can also be produced in precast plants. They are characterized by their ability to withstand large loads, durability, fast construction speed, and greater impact on the surrounding environment. The construction procedure is prefabrication, transportation, stacking, and pile sinking. Precast piles are piles of various materials and forms (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.) made in factories or construction sites. The piles are driven, pressed or vibrated into the soil using pile driving equipment. The precast piles that are widely used in China's construction field are mainly concrete precast piles and steel piles.

[0003] Existing reinforced concrete precast piles are prefabricated in prefabricated component processing plants. Steel frames and concrete are filled into pre-installed plate molds, and the concrete is removed for maintenance after solidification. After reaching the designed strength, it is transported to the construction site. However, there are the following problems in the pouring production process of existing precast square piles: on the one hand, in order to ensure the structural strength of the precast piles after concrete pouring, operators usually hold a vibrating rod to vibrate the concrete in real time when filling concrete into the plate mold to remove the air inside. However, this vibration method is single, which leads to small bubbles and potholes on the outside of the precast piles after solidification, thereby affecting the quality of the finished product and posing operational shortcomings. On the other hand, as the concrete solidifies and takes shape, the concrete will adhere to the mold. In order to facilitate the subsequent lifting and transportation of the finished precast piles, the operator needs to use a hammer to repeatedly knock the gap between the concrete and the mold to remove the mold, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The invention discloses a precast pile production casting device, which aims to solve the technical problems that the existing precast pile production casting device is complicated to operate and has disadvantages in actual use.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A precast pile production casting equipment includes a base, a casting mechanism for casting and shaping the precast piles is provided on the top of the base, the casting mechanism includes a conical kit and a tail plate member fixedly mounted on the top of the base, the conical kit and the tail plate member are symmetrically distributed in the horizontal direction, two outer plates are symmetrically distributed between the conical kit and the tail plate member, the outer plates are slidably mounted on the top of the base, and an inner plate is slidably mounted on the close surfaces of the two outer plates, the outer opening size of the outer plate is consistent with the inner opening size of the inner plate; a spring is provided between the outer plate and the inner plate, the end of the inner plate is fixedly connected to the conical kit by bolts, and at the same time, the two sides of the conical kit are fixedly connected by screws The L-shaped side plates are fixedly installed with bolts, and in the initial state, the outer sides of the two outer plates are in contact with the L-shaped side plates; an auxiliary mechanism is provided on the side of the casting mechanism, and the auxiliary mechanism includes a slide rail fixedly installed on the top of each outer plate, and a sliding platform is slidably installed on the top of each slide rail, and the lower surface of the sliding platform is flush with the upper surface of the inner plate; a fixing mechanism is provided on the top of the casting mechanism to maintain the structural stability during the casting of precast piles; by disassembling the fixing mechanism, the spring rebounds and drives the outer plate to generate a vibration force, thereby assisting the inner plate and the precast pile to be initially demolded, and at the same time, the reset outer plate will collide with the L-shaped side plate, thereby assisting the tapered kit to be demolded.

[0007] The pouring mechanism is clamped and fixed by the fixing mechanism, and then concrete is poured into the interior of the pouring mechanism. At this time, the auxiliary mechanism provides vertical vibration force by hitting the top of the inner plate to improve the density of pouring. After completing the preparation of the precast piles, the auxiliary mechanism provides horizontal outward vibration force by hitting the top edge of the outer plate to assist the precast piles in fully demoulding.

[0008] By arranging a casting mechanism that can be quickly encapsulated on the top of the base, the operator assembles the casting mechanism and fixes it with the clamping mechanism. On the premise of maintaining the structural stability of the casting mechanism, concrete is filled into the casting mechanism, and solidification completes the preparation of the precast pile. In the process of concrete solidification, an additional auxiliary mechanism is used to vibrate and remove bubbles in the gap between the casting mechanism and the concrete, thereby ensuring the quality of the precast pile after formation. At the same time, when the precast pile is demoulded, the auxiliary mechanism that is started again can impact and vibrate the outer wall of the casting mechanism, thereby assisting in separating the precast pile and the casting mechanism, thereby greatly improving the efficiency and convenience of precast pile preparation.

[0009] In a preferred embodiment, the casting mechanism further includes a plurality of straight rods fixedly mounted on the side surfaces of each inner plate, the straight rods extending from the interior of the outer plate, the springs being sleeved on the outer sides of the straight rods, and the ends of the springs being fixedly connected to the straight rods and the outer plate, respectively.

[0010] By fixing a conical kit and a tail plate on the top of the base, and providing a sliding outer plate between the conical kit and the tail plate, the centering movement of the outer plate is used to synchronously drive the two inner plates, so that the inner plates cooperate with the conical kit and the tail plate to form a seal. The operator then pours concrete into the sealed space and waits until the concrete solidifies to complete the preparation of the precast piles. At the same time, after the preparation of the precast piles is completed, the spring pushes the outer plate and the inner plate, and cooperates with the impact of the auxiliary mechanism to better assist the workers in completing the demoulding process of the precast piles, thereby greatly improving the efficiency of the precast pile preparation.

[0011] In a preferred embodiment, the auxiliary mechanism also includes a group of motors symmetrically installed on the top of each sliding table, and a knocking piece is fixed to the end of the output shaft of each motor. The knocking piece is "S"-shaped. When the knocking piece rotates counterclockwise, its end hits the top of the inner plate, and when the knocking piece rotates clockwise, its end hits the inner side of the top of the outer plate.

[0012] By additionally providing a slide rail and a sliding table structure on the top of the outer plate, when the operator pours concrete into the sealed space formed by the inner plate, the conical kit and the tail plate, the sliding table is used to slide along the top of the slide rail to drive the motor to move synchronously. At the same time, the knocking piece at the end of the motor will continuously knock on the inner plate, thereby eliminating bubbles between the inner plate and the concrete by vibration, thereby improving the quality of the finished precast pile; when the outer plate is reset outward, the knocking piece at the end of the motor will be aligned with the outer plate, thereby knocking on the outer plate, and driving the inner plate by outward vibration, causing the inner plate to break away from the adhesion state with the precast pile, thereby completing the rapid demoulding of the precast pile, thereby greatly improving the convenience of traditional precast pile preparation.

[0013] In a preferred embodiment, the fixing mechanism includes slots symmetrically opened at both ends of the outer plate, a card plate is squeezed and clamped inside each slot, a bolt rod is threadedly connected between the two cards symmetrically distributed in the horizontal direction, and a nut is threadedly sleeved on the end of the bolt rod, toothed strips are symmetrically provided at the top of both ends of the outer plate, and a flexible card block is provided at the inner top of the inner plate, and the toothed strip is squeezed and contacted with the flexible card block.

[0014] By providing a slot structure at the end of the outer plate and engaging with the clamping plate connected by the bolt rod, the structural stability of the inner plate is enhanced when the inner plate is matched with the tapered kit and the tail plate part, thereby ensuring the completion of the casting.

[0015] In a preferred embodiment, the striking member includes a rotor fixedly mounted on the end of the motor output shaft, an inertia member is slidably mounted inside each end of the rotor, and each inertia member is connected to the inner wall of the rotor via an elastic sheet.

[0016] By setting the striking piece as a rotor with its own inertia piece, the inertia generated when the motor drives the rotor to rotate is used to throw the inertia piece out, causing the inertia piece to hit the inner plate and the outer plate, forming a striking force, thereby ensuring the integrity of the operation of this equipment.

[0017] From the above, it can be seen that the precast pile production and casting equipment provided by the present invention has the following technical effects.

[0018] A conical kit and a tail plate are fixedly installed on the top of the base, and a sliding outer plate is provided between the conical kit and the tail plate. The centering movement of the outer plate is used to synchronously drive the two inner plates, so that the inner plates cooperate with the conical kit and the tail plate to form a sealed space. The operator then pours concrete into the sealed space, and uses a simple assembly structure to improve the convenience of prefabricated pile preparation. In this process, a slide rail and a slide table are additionally provided on the top of the outer plate, and the sliding table is used to slide along the top of the slide rail to drive the motor and the striking piece to move synchronously. The motor moves step by step, and the striking piece will continuously strike the inner plate, thereby eliminating the bubbles between the inner plate and the concrete by vibration, thereby improving the quality of the finished precast pile. When the concrete solidifies, the outer plate that is no longer restricted by the card slot and card plate will reset outward, and the striking piece at the end of the motor will be aligned with the outer plate, thereby striking the outer plate outward. The outer plate will drive the inner plate to break away from the precast pile, thereby completing the rapid demoulding of the precast pile, thereby greatly improving the convenience and functionality of the traditional precast pile preparation.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] The present invention discloses a precast pile production and casting device which is mainly used in the scenario of precast pile production and preparation.

[0034] Reference Figures 1 to 12, including a base 1, a casting mechanism 2 for casting and shaping precast piles is provided on the top of the base 1, the casting mechanism 2 includes a conical kit 201 and a tail plate 202 fixedly mounted on the top of the base 1, the conical kit 201 and the tail plate 202 are symmetrically distributed in the horizontal direction, and two outer plates 203 are symmetrically distributed between the conical kit 201 and the tail plate 202, the outer plates 203 are slidably mounted on the top of the base 1, and an inner plate 204 is slidably mounted on the close surfaces of the two outer plates 203, and the outer opening size of the outer plate 203 is consistent with the inner opening size of the inner plate 204; a spring 206 is provided between the outer plate 203 and the inner plate 204, and the end of the inner plate 204 is fixedly connected to the conical kit 201 by bolts, and at the same time, the two sides of the conical kit 201 are fixedly connected by bolts An L-shaped side plate 208 is fixedly installed. In the initial state, the outer sides of the two outer plates 203 are in contact with the L-shaped side plate 208; an auxiliary mechanism 3 is provided on the side of the casting mechanism 2, and the auxiliary mechanism 3 includes a slide rail 301 fixedly installed on the top of each outer plate 203, and a sliding platform 302 is slidably installed on the top of each slide rail 301, and the lower surface of the sliding platform 302 is flush with the upper surface of the inner plate 204; a fixing mechanism 4 is provided on the top of the casting mechanism 2 to maintain the structural stability during the casting of the precast pile; by removing the fixing mechanism 4, the spring 206 rebounds and drives the outer plate 203 to generate a vibration force, thereby assisting the inner plate 204 and the precast pile to perform preliminary demoulding, and at the same time, the reset outer plate 203 will collide with the L-shaped side plate 208, thereby assisting the tapered kit 201 to perform demoulding;

[0035] The pouring mechanism 2 is clamped and fixed by the fixing mechanism 4, and then concrete is poured into the interior of the pouring mechanism 2. At this time, the auxiliary mechanism 3 provides vertical vibration force by hitting the top of the inner plate 204 to improve the density of pouring. After completing the preparation of the precast pile, the auxiliary mechanism 3 provides horizontal outward vibration force by hitting the top edge of the outer plate 203 to assist the precast pile in fully demoulding.

[0036] In this embodiment, the operator fixes the pouring mechanism 2 by the fixing mechanism 4, and places the precast pile steel frame inside the pouring mechanism 2, and then uses the external crane to lift the concrete tank to the top of the pouring mechanism 2, and slowly pours concrete into the pouring mechanism 2. During this process, other operators start the auxiliary mechanism 3, causing the auxiliary mechanism 3 to move horizontally along the top of the pouring mechanism 2, and knock on the inner wall of the pouring mechanism 2 while moving, causing the concrete close to the inner wall of the pouring mechanism 2 to vibrate, thereby shaking out the bubbles inside the concrete. After that, the concrete solidifies and forms. After the concrete is formed, the operator removes the fixing mechanism 4 and starts the auxiliary mechanism 3 again, causing the auxiliary mechanism 3 to knock on the outer wall of the pouring mechanism 2, thereby releasing the precast piles adhered to the inner wall of the pouring mechanism 2. After that, the operator uses the crane to hook the components embedded in the precast piles in advance and lift the precast piles out from the inside of the pouring mechanism 2.

[0037] Reference Figures 1 to 4 、 Figures 8 and 9 In a preferred embodiment, the casting mechanism 2 also includes a plurality of straight rods 205 fixedly installed on the side of each inner plate 204, the straight rods 205 pass through the inside of the outer plate 203, and the springs 206 are sleeved on the outside of the straight rods 205, and the ends of the springs 206 are respectively fixedly connected to the straight rods 205 and the outer plate 203.

[0038] The operator slowly aligns and clamps the two outer plates 203 through the fixing mechanism 4. While the outer plates 203 are slowly moving in the center, the inner plates 204 are driven to move synchronously through the spring 206 and the straight rod 205, causing the two inner plates 204 to move in the center until they are squeezed and contacted with the outer sides of the tapered sleeve 201 and the tail plate 202. At this time, the outer plates 203 that continue to move in the center will overcome the pulling force of the spring 206 and thus move close to the inner plates 204 until the outer plates 203 and the inner plates 204 are fitted together. The specific state is as follows: Figure 9As shown; a casting mold cavity is formed between the inner side plate 204, the cone kit 201 and the tail plate 202. At this time, the operator hoists the precast pile steel frame to the inside of the space, and then uses the external crane to hoist the concrete tank to the top of the inner side plate 204, the cone kit 201 and the tail plate 202, and slowly pours concrete into the casting mold cavity of the inner side plate 204, the cone kit 201 and the tail plate 202. During this process, other operators start the auxiliary mechanism 3, causing the auxiliary mechanism 3 to move horizontally along the top of the outer plate 203, while moving the top of the inner side plate 204. The knocking causes the concrete close to the inner plate 204 to vibrate, thereby shaking out the bubbles inside the concrete (in this process, other operators hold vibrators to vibrate the middle of the concrete layer to further improve the overall compaction effect). After that, the concrete solidifies and takes shape. After the concrete is formed, the operator removes the fixing mechanism 4. At this time, since the inner plate 204 is adhered to the solidified concrete, the outer plate 203 that has lost its extrusion restriction will be pulled by the stretched spring 206, thereby returning to the outside, causing the outer plate 203 and the inner plate 204 to separate and fit together. The specific state is as follows: Figure 8 and Figure 11 As shown, the outer plate 203 that is simultaneously resetting and moving will collide with the L-shaped side plate 208, causing the L-shaped side plate 208 to generate vibration and transmit it to the interior of the conical kit 201, assisting the precast piles to be demoulded from the conical kit 201. At this time, the operator activates the auxiliary mechanism 3 again, causing the auxiliary mechanism 3 to generate an outward vibration force on the outer plate 203, thereby causing the outer plate 203 to drive the inner plate 204 to separate from the precast piles.

[0039] Among them, it needs to be supplemented that: a number of reinforcing ribs 207 are fixed to the side of each inner plate 204, the reinforcing ribs 207 pass through the inside of the outer plate 203, and the reinforcing ribs 207 and the straight rods 205 are symmetrically distributed along the vertical direction, and a guide rail 5 is provided on the top of the base 1, and the two outer plates 203 are slidably installed on the top of the guide rail 5.

[0040] Furthermore, it is supplemented that a positioning portion 2021 is provided on the top of the tail plate 202. The positioning portion 2021 is squeezed and restricted between the two inner side plates 204. The inner side plate 204 that moves in the center will squeeze and contact the two sides of the positioning portion 2021, thereby stopping movement.

[0041] Reference Figures 1 to 3 、 Figures 5 and 6 、 Figures 8 and 9In a preferred embodiment, the auxiliary mechanism 3 also includes a group of motors 303 symmetrically installed on the top of each sliding table 302, and a knocking piece 304 is fixed to the end of the output shaft of each motor 303. The knocking piece 304 is "S"-shaped. When the knocking piece 304 rotates counterclockwise, its end hits the top of the inner plate 204. When the knocking piece 304 rotates clockwise, its end hits the inner side of the top of the outer plate 203.

[0042] The operator slowly aligns and clamps the two outer plates 203 through the fixing mechanism 4. When the outer plate 203 moves slowly in the center, the auxiliary mechanism 3 will be driven to move synchronously until the outer plate 203 and the inner plate 204 are in contact. At this time, the motor 303 and the knocking member 304 will be close to the inner plate 204. The specific state is as follows: Figure 9 As shown; as the operators slowly pour concrete into the casting mold cavity of the inner side plate 204, the cone kit 201 and the tail plate 202, during this process, other operators start the motor 303 and pull the sliding table 302 to move along the top of the slide rail 301, driving the motor 303 and the knocking piece 304 to move horizontally along the top of the outer side plate 203. While moving, the rotating motor 303 will synchronously drive the knocking piece 304 to rotate counterclockwise, causing the rotating knocking piece 304 to continuously knock on the top of the inner side plate 204 in the vertical direction, producing The up and down vibration force generated can make the concrete settle and compact faster, and shake out the bubbles inside the concrete. After that, wait until the concrete solidifies and takes shape. After the concrete is formed, the operator removes the fixing mechanism 4. At this time, since the inner plate 204 is adhered to the solidified concrete, the outer plate 203 that has lost its extrusion restriction will be pulled by the stretched spring 206, thereby returning to the outside. At the same time, the outer plate 203 that is returning to the outside will synchronously drive the auxiliary mechanism 3. At this time, the motor 303 and the knocking piece 304 will lose their close relationship with the inner plate 204. The specific state is as follows: Figure 8 As shown; at this time, the operator starts the motor 303 again, and the rotating motor 303 will synchronously drive the knocking member 304 to rotate clockwise, causing the rotating knocking member 304 to continuously knock the top of the outer plate 203 outward, thereby causing the outer plate 203 to drive the inner plate 204, generating a vibration force outward on the inner plate 204, allowing the precast piles adhered to the inner plate 204 to break away from the adhesion state.

[0043] Among them, it needs to be supplemented that: a central area 305 is opened on the side of each sliding platform 302, and the knocking piece 304 is distributed inside the central area 305, and a handle 306 is fixed at an angle on the top of each sliding platform 302 to facilitate workers to hold and pull the sliding platform 302 to move.

[0044] Furthermore, it is supplemented that: the striking member 304 includes a rotor 3041 fixedly mounted on the end of the output shaft of the motor 303, and an inertia member 3042 is slidably mounted inside each end of the rotor 3041. Each inertia member 3042 is connected to the inner wall of the rotor 3041 by an elastic sheet 3043. When the motor 303 is started and drives the rotor 3041 to rotate, the rotating rotor 3041 will rely on inertia to throw the inertia member 3042 out from the inside of the rotor 3041, causing the inertia member 3042 to squeeze and hit the top edge of the outer plate 203 and the top of the inner plate 204. When the motor 303 stops rotating, the inertia member 3042, which has lost the influence of inertia, will be pulled by the elastic sheet 3043, thereby resetting and moving, and retracting into the interior of the rotor 3041. The end of the inertia member 3042 is an arc surface, and the top edge of the outer plate 203 is also an arc surface.

[0045] Among them, the main effect of the "S" shape of the knocking piece 304 is: during the clockwise rotation of the knocking piece 304, the end of the knocking piece 304 can better apply horizontal knocking to the outer plate 203 to help the precast pile to be demolded; and during the counterclockwise rotation of the knocking piece 304, the inertia piece 3042 at the end of the knocking piece 304 can better retract and apply vertical knocking to the top of the inner plate 204. The vertical vibration force can better help the concrete to settle and compact.

[0046] Reference Figures 1 to 4 、 Figure 7 In a preferred embodiment, the fixing mechanism 4 includes a card slot 401 symmetrically opened at both ends of the outer plate 203, and a card plate 402 is squeezed and clamped inside each card slot 401. A bolt rod 403 is threadedly connected between the two card plates 402 symmetrically distributed in the horizontal direction, and a nut 404 is threadedly sleeved on the end of the bolt rod 403. Toothed strips 405 are symmetrically provided at the top of both ends of the outer plate 203, and a flexible card block 406 is provided at the inner top of the inner plate 204. The toothed strip 405 is squeezed and contacted with the flexible card block 406.

[0047] The operator holds the bolt rod 403 and inserts the two clamping plates 402 at the end of the bolt rod 403 into the inside of the clamping groove 401, and at the same time twists the nut 404 with a wrench, causing the nut 404 to move along the outside of the bolt rod 403, squeezing the clamping plate 402 while moving, causing the clamping plate 402 to move in the center, thereby driving the two outer plates 203 to slowly clamp in the center. During this process, the toothed edge strip 405 at the top of the outer plate 203 will slowly approach and squeeze the bottom of the flexible clamping block 406. A two-way threaded rod can also be used here to drive the outer plate 203 to move in the center. This is a simple replacement of the existing technology and will not be repeated here. Among them, the inner wall of the clamping plate 402 can be embedded with ball bearings or coated with lubricating oil to reduce the friction between it and the clamping groove 401 during disassembly.

[0048] Working principle: When in use, the operator holds the bolt rod 403 and inserts the two clamping plates 402 at the end of the bolt rod 403 into the inside of the clamping groove 401. At the same time, the nut 404 is screwed with an electric wrench, causing the nut 404 to move along the outside of the bolt rod 403, squeezing the clamping plate 402 while moving, causing the clamping plate 402 to move in the center, thereby driving the two outer plates 203 to slowly clamp in the center. While the outer plate 203 moves slowly in the center, the inner plate 204 is driven to move synchronously through the spring 206 and the straight rod 205, causing the two inner plates 204 to move in the center until The outer sides of the tapered sleeve 201 and the tail plate 202 are pressed and contacted, and then the tapered sleeve 201, the L-shaped side plate 208 and the inner side plate 204 are fixed with bolts. At this time, the inner side plate 204 cannot move in the center. By continuing to rotate the nut 404, the outer side plate 203 overcomes the tension of the spring 206 and approaches the inner side plate 204 until the outer side plate 203 is snapped into the inner side plate 204 and fits with the inner side plate 204. At this time, the lower surface of the sliding platform 302 is in contact with the upper surface of the inner side plate 204, and the knocking piece 304 is also located on the top of the inner side plate 204. The specific state is as follows: Figure 9 and Figure 10 As shown; a casting mold cavity is formed between the inner side plate 204, the cone kit 201 and the tail plate part 202. At this time, the operator hoists the precast pile steel bar skeleton to the inside of the space, and then uses the external crane to hoist the concrete tank to the top of the inner side plate 204, the cone kit 201 and the tail plate part 202, and slowly pours concrete into the casting mold cavity of the inner side plate 204, the cone kit 201 and the tail plate part 202. During this process, other operators start the motor 303 and pull the sliding table 302 to move along the top of the slide rail 301, thereby driving the motor 303 and the knocking piece 304 to move horizontally along the top of the outer plate 203. While moving, the rotating motor 303 will synchronously drive the knocking piece 304 to rotate counterclockwise, causing the rotating knocking piece 304 to continuously knock on the top of the inner side plate 204 (as shown in FIG. Figure 10As shown in the figure), the concrete close to the inner plate 204 is vibrated, thereby shaking out the bubbles inside the concrete (in this process, the vertical vibration force can improve the settlement and compaction effect of the concrete. Other operators hold vibrators to vibrate the middle of the concrete layer to prevent internal bubbles from appearing in places where the concrete layer is thick). After that, the concrete is solidified and formed. After the concrete is formed, the operator uses an external crane and hooks the middle parts of the two bolt rods 403 through two hook locks. The two bolt rods 403 are pulled upward by the crane, causing the clamping plate 402 to be separated from the clamping groove 401 due to the pulling force. At this time, since the inner plate 204 is adhered to the solidified concrete, the outer plate 203 that has lost its extrusion restriction will be pulled by the stretched spring 206, thereby quickly returning to the outside, causing the outer plate 203 and When the inner side plates 204 are separated and fitted, a vibration force is generated, which drives the inner side plates 204 and the precast piles to be initially demolded, and at the same time, the outer plate 203 that is reset and moves will hit the L-shaped side plates 208, causing the L-shaped side plates 208 to vibrate and transmit the vibration to the inside of the cone kit 201, assisting the precast piles to be demolded from the cone kit 201. At the same time, the toothed edge strip 405 at the top of the outer plate 203 will be affected by the pushing force of the spring 206 and quickly reset and move. While moving, the toothed edge strip 405 will continuously come into contact with the bottom of the flexible block 406, and the tooth grooves on the upper surface of the toothed edge strip 405 will come into contact with the flexible block 406, thereby further driving the inner side plate 204 to vibrate to assist the precast piles to be demolded. At this time, the motor 303 and the knocking member 304 will lose their close relationship with the inner side plate 204. The specific state is as follows Figure 8 As shown; at this time, the operator starts the motor 303 again, and the rotating motor 303 will synchronously drive the striking member 304 to rotate clockwise, causing the rotating striking member 304 to continuously strike the top of the outer plate 203 outward in the horizontal direction, thereby causing the outer plate 203 to drive the inner plate 204, generating an outward vibration force on the inner plate 204 (such as Figure 11 As shown), the precast piles adhered to the inner plate 204 are fully separated from the adhesion state. After that, the crane and the hook lock are used to hook the lifting components pre-buried in the precast piles, and the precast piles are lifted out from the inside of the casting mechanism 2 to complete the preparation of the precast piles.
