Description

Technical Field

[0001] The invention relates to the technical field of precast pile production equipment, and 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 being able to withstand heavy loads, being strong and durable, having a fast construction speed, and having a 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, and are driven, pressed, or vibrated into the soil using pile sinking equipment. The precast piles that are widely used in China's construction industry are mainly precast concrete piles and steel piles.

[0003] Existing reinforced concrete precast piles are prefabricated in prefabricated component processing plants, by filling the steel skeleton and concrete into the pre-installed plate mold, waiting for the concrete to solidify before removing the mold for maintenance, and transporting to the construction site after reaching the designed strength; however, the existing prefabricated square piles have the following problems during the casting and production process: on the one hand, in order to ensure the structural strength of the precast piles after concrete pouring, operators usually hold an additional vibrator to vibrate the concrete in real time when filling concrete into the plate mold to remove the air inside, but the 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 having operational shortcomings; on the other hand, as the concrete solidifies and forms, the concrete will adhere to the mold. In order to facilitate the subsequent lifting and transportation of the finished precast piles, the operator is required to use a hammer to repeatedly knock the gap between the concrete and the mold to demould, which is time-consuming and labor-intensive. Summary of the invention

[0004] The invention discloses a precast pile production casting device, aiming to solve the technical problem 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: A precast pile production casting equipment, comprising a base, a casting mechanism for casting and shaping the precast piles is arranged on the top of the base, the casting mechanism comprises a conical sleeve and a tail plate member fixedly mounted on the top of the base, the conical sleeve and the tail plate member are symmetrically distributed in the horizontal direction, two outer plates are symmetrically distributed between the conical sleeve and the tail plate member, the outer plates are slidably mounted on the top of the base, 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 arranged between the outer plate and the inner plate, the end of the inner plate is fixedly connected to the conical sleeve by bolts, and at the same time, the two sides of the conical sleeve are screwed The L-shaped side plate is fixedly installed by the bolt, and in the initial state, the outer sides of the two outer side plates are in contact with the L-shaped side plates; an auxiliary mechanism is arranged on the side of the casting mechanism, and the auxiliary mechanism includes a slide rail fixedly installed on the top of each outer side 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 side plate; a fixing mechanism is arranged on the top of the casting mechanism to maintain the structural stability during the casting of the precast piles; by disassembling the fixing mechanism, the spring rebounds and drives the outer side plate to generate a vibration force, thereby assisting the inner side plate and the precast pile to be initially demoulded, and the reset outer plate will collide with the L-shaped side plate, thereby assisting the tapered kit to be demoulded.

[0006] The pouring mechanism is clamped and fixed by the fixing mechanism, and then concrete is poured into 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 the preparation of the precast piles is completed, 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.

[0007] By providing 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, fills the interior of the casting mechanism with concrete while maintaining the structural stability of the casting mechanism, and solidifies to complete the preparation of the precast pile; in the process of concrete solidification, the gap between the casting mechanism and the concrete is vibrated and defoamed by an additional auxiliary mechanism, thereby ensuring the quality of the precast pile after forming, and 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 the separation of the precast pile and the casting mechanism, thereby greatly improving the efficiency and convenience of the precast pile preparation.

[0008] In a preferred embodiment, the casting mechanism also includes a plurality of straight rods fixedly mounted on the side of each inner plate, the straight rods passing through the interior of the outer plate, the springs being sleeved on the outside of the straight rods, and the ends of the springs being fixedly connected to the straight rods and the outer plate, respectively.

[0009] A conical kit and a tail plate are fixedly installed on the top of the base, and a sliding outer plate is arranged 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.

[0010] 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 outer plate, and when the knocking piece rotates clockwise, its end hits the inner side of the top of the inner plate.

[0011] By additionally arranging a slide rail and a slide 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, and the knocking piece at the end of the motor will continuously knock on 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 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.

[0012] In a preferred solution, the fixing mechanism includes card slots symmetrically opened at both ends of the outer plate, a card plate is squeezed and clamped inside each of the card slots, a bolt rod is threadedly connected between the two card plates symmetrically distributed in the horizontal direction, and a nut is threadedly sleeved on the end of the bolt rod, toothed edge strips are symmetrically arranged at the top of both ends of the outer plate, and a flexible card block is arranged at the inner top of the inner plate, and the toothed edge strip is squeezed and contacted with the flexible card block.

[0013] By providing a slot structure at the end of the outer plate and engaging with a clamping plate connected by a bolt rod, the structural stability of the inner plate is enhanced when the inner plate cooperates with the conical kit and the tail plate member, thereby ensuring the completion of the casting.

[0014] In a preferred solution, the knocking member includes a rotor fixedly mounted on the end of the motor output shaft, an inertia member is slidably mounted inside both ends of the rotor, and each of the inertia members is connected to the inner wall of the rotor via an elastic sheet.

[0015] By setting the striking piece as a rotor with its own inertia piece, the inertia piece is thrown out by utilizing the inertia generated when the motor drives the rotor to rotate, thereby causing the inertia piece to hit the inner side plate and the outer side plate to form a striking force, thereby ensuring the integrity of the operation of the equipment.

[0016] 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.

[0017] A cone kit and a tail plate are fixedly installed on the top of the base, and a sliding outer plate is arranged between the cone 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 cone kit and the tail plate to form a sealed space. The operator then pours concrete into the sealed space, and the convenience of preparing the prefabricated piles is improved by using a simple assembly structure. In this process, a slide rail and a slide table are additionally arranged on the top of the outer plate, and the sliding of the slide table along the top of the slide rail is used to drive the motor and the striking piece to move synchronously. The inner plate moves step by step, and the knocking piece will continuously knock on the inner plate, so as to eliminate the bubbles between the inner plate and the concrete by vibration, so as to improve the quality of the finished precast pile; and when the concrete solidifies, the outer plate that loses the restriction of the card slot and the card plate will reset outward, and the knocking piece at the end of the motor will be aligned with the outer plate, so as to knock the outer plate outward, and the outer plate will drive the inner plate to break the adhesion with the precast pile, so as to complete the rapid demoulding of the precast pile, thereby greatly improving the convenience and functionality of the preparation of traditional precast piles.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0032] The precast pile production and casting equipment disclosed in the present invention is mainly used in the scene of precast pile production and preparation.

[0033] Reference Figures 1 to 12, including a base 1, a casting mechanism 2 for casting and molding the precast piles is arranged on the top of the base 1, the casting mechanism 2 includes a conical kit 201 and a tail plate 202 fixedly installed on the top of the base 1, the conical kit 201 and the tail plate 202 are symmetrically distributed in the horizontal direction, two outer plates 203 are symmetrically distributed between the conical kit 201 and the tail plate 202, the outer plates 203 are slidably installed on the top of the base 1, and an inner plate 204 is slidably installed 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 arranged between the outer plate 203 and the inner plate 204, 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 bolted An L-shaped side plate 208 is fixedly installed, and the outer sides of the two outer side plates 203 are in contact with the L-shaped side plate 208 in the initial state; an auxiliary mechanism 3 is arranged 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 side 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 side plate 204; a fixing mechanism 4 is arranged on the top of the casting mechanism 2 to maintain the structural stability during the casting of the precast pile; by disassembling the fixing mechanism 4, the spring 206 rebounds and drives the outer side plate 203 to generate a vibration force, thereby assisting the inner side plate 204 and the precast pile to be initially demoulded, 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 be demoulded; The pouring mechanism 2 is clamped and fixed by the fixing mechanism 4, and then concrete is poured into the pouring mechanism 2. At this time, the auxiliary mechanism 3 provides a vertical vibration force to improve the density of pouring by hitting the top of the inner plate 204. After the preparation of the precast piles is completed, the auxiliary mechanism 3 provides a horizontal outward vibration force to assist the precast piles to be fully demoulded by hitting the top edge of the outer plate 203.

[0034] In this embodiment: the operator fixes the pouring mechanism 2 through the fixing mechanism 4, and at the same time places the precast pile steel bar skeleton 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, driving the concrete close to the inner wall of the pouring mechanism 2 to vibrate, thereby shaking out the bubbles inside the concrete, and then wait until 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, so that the precast pile adhered to the inner wall of the pouring mechanism 2 is released from the adhesion state. After that, the operator uses the crane to hook the components pre-buried in the precast pile in advance, and lifts the precast pile out from the inside of the pouring mechanism 2.

[0035] Reference Figures 1 to 4 , Figures 8 to 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.

[0036] The operator slowly clamps the two outer plates 203 in the center through the fixing mechanism 4. When the outer plates 203 slowly move in the center, the inner plates 204 are driven to move synchronously through the spring 206 and the straight rod 205, so that the two inner plates 204 move in the center until they are pressed and contacted with the outer sides of the conical sleeve 201 and the tail plate 202. At this time, the outer plate 203 that continues to move in the center will overcome the pulling force of the spring 206, so as to get close to the inner plate 204, until the outer plate 203 and the inner plate 204 fit together. The specific state is as follows: Fig. 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 side plate 203, and while moving, the top of the inner side plate 204 is The concrete close to the inner plate 204 is struck 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 resetting outward, causing the outer plate 203 and the inner plate 204 to separate and fit together. The specific state is as follows: Figure 8 and Fig.11 As shown, the outer plate 203 that is reset and moved at the same time will collide with the L-shaped side plate 208, causing the L-shaped side plate 208 to vibrate and transmit the vibration to the inside of the conical kit 201, assisting the precast piles to be demoulded from the conical kit 201. At this time, the operator starts 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.

[0037] Among them, it should be additionally explained 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.

[0038] Further, it is supplemented that a positioning portion 2021 is provided on the top of the tail plate 202, and the positioning portion 2021 is squeezed and restricted between the two inner side plates 204. The inner side plate 204 moving in the center will be squeezed and contacted with the two sides of the positioning portion 2021, thereby stopping the movement.

[0039] Reference Figures 1 to 3 , Figures 5 and 6 , Figures 8 to 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 at 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 outer plate 203. When the knocking piece 304 rotates clockwise, its end hits the inner side of the top of the inner plate 204.

[0040] 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: Fig. 9 As shown; as the operators slowly pour concrete into the casting molds 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 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, when the concrete solidifies and takes shape, 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 the extrusion restriction will be pulled by the stretched spring 206, so that it will reset outward. At the same time, the reset outer plate 203 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 piece 304 to rotate clockwise, causing the rotating knocking piece 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, so that the precast piles adhered to the inner plate 204 are separated from the adhesion state.

[0041] It should be noted that a center area 305 is provided on the side of each sliding platform 302, and a knocking piece 304 is distributed inside the center area 305. 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.

[0042] Further, 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 the two ends of the rotor 3041 respectively, and each inertia member 3042 is connected to the inner wall of the rotor 3041 through 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 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 that 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.

[0043] Among them, the main effect of the "S" shape of the knocking piece 304 is: when the knocking piece 304 rotates clockwise, the end of the knocking piece 304 can better apply horizontal knocking to the outer plate 203 to help the precast pile to be demoulded; and when the knocking piece 304 rotates counterclockwise, 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.

[0044] 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, and 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, and toothed edge strips 405 are symmetrically arranged at the top of both ends of the outer plate 203, and a flexible card block 406 is arranged at the inner top of the inner plate 204, and the toothed edge strip 405 is squeezed and contacted with the flexible card block 406.

[0045] 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 slot 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 located 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 prior art and will not be repeated here. 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 slot 401 during disassembly.

[0046] 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, and at the same time, twists the nut 404 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 will be 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 side 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 by 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 pulling force 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 at the top of the inner side plate 204. The specific state is as follows: Fig. 9 and Fig.10 As shown; a casting mold cavity is formed between the inner side plate 204, the conical kit 201 and the tail plate 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 conical kit 201 and the tail plate 202, and slowly pours concrete into the casting mold cavity of the inner side plate 204, the conical 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 sliding rail 301, thereby 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 (such as Fig.10As shown in the figure), the concrete close to the inner plate 204 is driven to vibrate, 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, and other operators hold vibrators to vibrate the middle part 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 part of the two bolt rods 403 through two hook locks, and pulls the two bolt rods 403 upwards through the crane, causing the clamping plate 402 to be separated from the clamping groove 401 due to the pulling force. At this time, due to the adhesion of the inner plate 204 and the solidified concrete, the outer plate 203 that has lost the extrusion restriction will be pulled by the stretched spring 206, so that it will quickly return to the outside, causing the outer plate 203 and When the inner side plate 204 separates and fits together, vibration force is generated, which drives the initial demoulding between the inner side plate 204 and the precast pile, and the outer side plate 203 that is reset and moves at the same time will hit the L-shaped side plate 208, thereby causing the L-shaped side plate 208 to vibrate and transmit it to the inside of the conical kit 201, assisting the demoulding of the precast pile and the conical kit 201. At the same time, the toothed edge strip 405 located at the top of the outer side plate 203 will be affected by the driving force of the spring 206 and quickly reset and move together. While moving, the toothed edge strip 405 continuously squeezes and contacts with the bottom of the flexible block 406, and the tooth groove on the upper surface of the toothed edge strip 405 squeezes and contacts with the flexible block 406, thereby further driving the inner side plate 204 to vibrate to assist the demoulding of the precast pile. At this time, the motor 303 and the knocking piece 304 will lose their close relationship with the inner side plate 204. The specific state is as follows Figure 8 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 Fig.11 As shown), the precast piles adhered to the inner side plate 204 are completely separated from the adhesion state. After that, the hoisting components pre-buried in the precast piles are hooked by the crane and the hook lock, and the precast piles are lifted out from the inside of the casting mechanism 2 to complete the preparation of the precast piles.
