Abstract
Description
Technical Field
[0001] This invention relates to the field of precast concrete component manufacturing technology, specifically to a device for demolding and placing precast concrete components. Background Technology
[0002] In the production process of precast concrete components, the mold is the core carrier for component forming. The cleanliness of its surface directly determines the dimensional accuracy and appearance quality of the subsequent precast components. Therefore, the mold must be thoroughly cleaned before reuse to remove concrete residue, dust and other debris adhering to the inner and outer walls of the mold. This is to avoid defects such as pitting, bumps and dimensional deviations on the surface of the component caused by residue residue, and to ensure that the component meets the design standards and usage requirements.
[0003] Traditional mold cleaning methods rely heavily on manual operation, mainly through manual knocking, scraping, wire brush grinding, or high-pressure water gun washing. This cleaning mode is inefficient and cannot meet the rapid cleaning needs of a large number of molds in large-scale production. In the traditional production process, the cleaning process is independent of the demolding and transfer processes. The cleaning operation requires a separate work area, dedicated cleaning personnel and equipment, and consumes a lot of time, resulting in a lengthy and cumbersome overall production process with poor process connection.

[0014] Preferably, a collection box one and a collection box two are provided between the two sides of the track.
[0015] This invention provides a device for demolding and placing precast concrete components. It has the following advantages: 1. The suspension mechanism of this invention uses a crane trolley in conjunction with a winding machine and steel cables, which can not only achieve smooth horizontal movement of the side mold or top mold, but also control its vertical lifting. The inner wall design of the U-shaped frame can physically scrape the outer wall of the suspended mold to initially remove concrete residue.

[0017] 3. This invention utilizes an air pipe to create a high-pressure airflow that blows onto the mold surface using the compressed air generated when the mold enters the U-shaped frame. By employing components such as a sleeve, retaining ring, sliding rod, and tension spring, a negative pressure environment is created by expelling internal air after the mold enters the U-shaped frame, thereby firmly adhering the mold to the inner wall of the U-shaped frame.
[0018] 4. The present invention uses a transmission mechanism such as a rack, spur gear, or bevel gear to automatically lower and adhere to the surface of the bottom mold during the process of transporting components to the destination and returning. The scraper can automatically clean the bottom mold residue by utilizing the walking power of the moving trolley. Attached Figure Description

Detailed Implementation
[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0022] Please see the appendix Figure 1 - Appendix Figure 10 This invention provides a demolding and mold placement device for precast concrete components, including a track 1 and a hanger 2. A moving trolley 3 is provided inside the track 1. A demolding mechanism 4 is provided on the upper surface of the moving trolley 3. A bottom mold 5 is provided on the upper surface of the demolding mechanism 4. A side mold or top mold 6 is provided on the upper surface of the bottom mold 5. A suspension mechanism 7 is provided inside the hanger 2. The suspension mechanism 7 is detachably connected to the side mold or top mold 6. A fixed frame 8 is fixedly connected to the suspension mechanism 7. A U-shaped frame 9 is fixedly connected to the outer wall of the fixed frame 8. A flared mouth 10 is fixedly connected to the lower surface of the U-shaped frame 9.
[0023] Specifically, this equipment is mainly used for demolding and placement during the production of precast concrete components. The equipment comprises two core supporting structures: a track 1 and a hanger 2. The track 1 serves as a mobile load-bearing base, and its interior contains a movable trolley 3 that can move freely along the length of the track 1. A demolding mechanism 4 for separating the precast component from the mold is fixedly installed on the upper surface of the trolley 3. A bottom mold 5 is fixedly installed on the upper surface of the demolding mechanism 4. The bottom mold 5 serves as the bottom load-bearing structure for forming the precast concrete component, and a side mold or top mold 6 is mounted on top of it. The side mold and top mold, together with the bottom mold 5, form the forming cavity of the precast concrete component, used to define the external dimensions of the precast component. The hanger 2 spans above the track 1 and contains a suspension mechanism 7 that can move along the length of the hanger 2. This suspension mechanism 7 is detachably connected to the side mold or top mold 6, facilitating quick connection and lifting during demolding operations. A fixed frame 8 is fixedly connected to the lower part of the suspension mechanism 7. A U-shaped frame 9 is integrally fixed to the outer wall of the fixed frame 8. A funnel-shaped opening 10 is fixedly installed on the lower surface of the U-shaped frame 9. The funnel-shaped opening 10 has a funnel-shaped structure with a smaller upper end and a larger lower end. In the specific operation, the track 1 provides stable support for the moving trolley 3, ensuring that the moving trolley 3 can move smoothly. The core function of the suspension mechanism 7 is to suspend the side mold or top mold 6. After the demolding operation is completed, the side mold or top mold 6 is slowly lifted by the suspension mechanism 7. During the lifting process, the side mold or top mold 6 is accurately inserted into the interior of the U-shaped frame 9 under the guidance of the funnel-shaped opening 10. By using the contact between the inner wall of the U-shaped frame 9 and the outer wall of the side mold or top mold 6, the concrete residue attached to the outer wall of the side mold or top mold 6 is scraped off and peeled off, realizing the initial cleaning of the mold.
[0024] The demolding mechanism 4 includes a rotating chassis 401, which is fixedly installed on the upper surface of the moving trolley 3. The upper surface of the rotating chassis 401 is fixedly installed on the lower surface of the bottom mold 5. A lifting machine 402 is fixedly connected to the upper surface of the rotating chassis 401, and the output end of the lifting machine 402 is located inside the bottom mold 5.
[0025] Specifically, the demolding mechanism 4, as the core component for separating the precast component from the mold, includes a rotating base 401. The rotating base 401 is bolted to the upper surface of the moving trolley 3, and its installation position corresponds to the center position of the moving trolley 3 to ensure uniform force distribution. The upper surface of the rotating base 401 is fixedly connected to the lower surface of the bottom mold 5, allowing the bottom mold 5 to rotate together with the rotating base 401. The rotating base 401 can be driven by a servo motor in conjunction with a reduction gear mechanism, enabling precise angle adjustment. By rotating the rotating base 401, the angle and position of the entire bottom mold 5, side molds, top mold, and the precast component after molding can be flexibly adjusted, facilitating the smooth progress of subsequent demolding operations and allowing operators to easily inspect and process the components. A lifting machine 402 is fixedly connected to the upper surface of the rotating chassis 401. The lifting machines 402 are evenly distributed on the upper surface of the rotating chassis 401, and their output ends penetrate through the rotating chassis 401 and extend into the interior of the bottom mold 5. The top end of the output end of the lifting machine 402 is fixedly connected to the bearing plate inside the bottom mold 5. In this application, the lifting machine 402 adopts a common hydraulic lifting method, which can slowly lift the bearing plate upward during demolding, thereby driving the precast component to move upward, so that the precast component gradually separates from the bottom mold 5, side mold, and top mold, avoiding damage to the surface of the precast component or deformation of the mold due to excessive lifting speed or uneven force.
[0026] The suspension mechanism 7 includes a lifting trolley 701, which is located inside the hanger 2. A winding machine 702 is fixedly connected to the lower surface of the lifting trolley 701, and a steel cable 703 is provided on the outer wall of the winding machine 702.
[0027] Specifically, the suspension mechanism 7 is used to suspend and transport the side mold or top mold 6. Its specific structure includes a lifting trolley 701, which is installed inside the hanger 2. The hanger 2 has guide rails matching the lifting trolley 701, allowing it to move smoothly along the length of the hanger 2, thereby adjusting the horizontal position of the suspended side mold or top mold 6. A winding machine 702 is bolted to the lower surface of the lifting trolley 701. The winding machine 702 uses an electric winding method and is equipped with a braking device to achieve precise winding and positioning of the steel cable 703, preventing accidental slippage. The outer wall of the winding machine 702 is wound with the steel cable 703, which is made of high-strength steel and can withstand the weight of the side mold or top mold 6. A hook is fixedly installed at the bottom end of the steel cable 703, which can be securely connected to the lifting lugs on the side mold or top mold 6 to prevent detachment during suspension. After being drawn out from the winding machine 702, the steel cable 703 passes through the center of the U-shaped frame 9. A sealing gasket is installed at the contact point between the steel cable 703 and the U-shaped frame 9. The sealing gasket is made of wear-resistant and highly elastic rubber material, which can reduce frictional loss between the steel cable 703 and the U-shaped frame 9 and ensure the sealing of the interior of the U-shaped frame 9. In actual operation, the hanger 2 provides stable support for the lifting trolley 701. The movement of the lifting trolley 701 drives the side mold or top mold 6 to achieve horizontal transfer. The winding action of the winding machine 702 tightens the steel cable 703, slowly lifting the side mold or top mold 6. The unwinding action of the winding machine 702 loosens the steel cable 703, slowly lowering the side mold or top mold 6.
[0028] An air pipe 11 is fixedly connected to the outer wall of the U-shaped frame 9, and the lower end of the air pipe 11 is fixedly connected to the outer wall of the flared mouth 10.
[0029] Specifically, to further improve the mold cleaning effect, air pipes 11 are fixedly connected to the outer wall of the U-shaped frame 9, and the air pipes 11 are evenly distributed on the outer wall of the U-shaped frame 9. The lower end of the air pipe 11 is fixedly connected to the outer wall of the flared opening 10, and the connection points of the air pipe 11 with the flared opening 10 and the U-shaped frame 9 are all sealed to prevent gas leakage. Since the upper side of the U-shaped frame 9 is a closed structure, when the side mold or top mold 6 slides into the U-shaped frame 9 under the guidance of the flared opening 10, it will compress the air inside the U-shaped frame 9, causing the air pressure inside the U-shaped frame 9 to rise. The high-pressure air will enter the interior of the air pipes 11 and be discharged from the other end of the air pipes 11. The discharged high-pressure air is directly blown towards the outer wall of the side mold or top mold 6. Combined with the scraping action of the inner wall of the U-shaped frame 9 on the outer wall of the mold, the concrete residue attached to the outer wall of the mold can be more thoroughly removed, achieving efficient cleaning of the mold. To prevent air backflow and ensure that high-pressure air can be stably blown to the outer wall of the mold, a one-way valve is fixedly installed inside the air pipe 11. The one-way valve only allows air to flow from the inside of the U-shaped frame 9 to the outside of the air pipe 11, and prohibits air from flowing back from the outside of the air pipe 11 to the inside of the U-shaped frame 9.
[0030] The outer wall of the track 1 is fixedly connected to a placement groove 12, and the inside of the placement groove 12 is fixedly connected to a rubber pad 13. The upper surface of the rubber pad 13 is provided with a flared opening.
[0031] Specifically, a placement groove 12 is fixedly connected to the outer wall of track 1. The placement groove 12 is used for temporary storage of the side mold or top mold 6 after demolding. The placement groove 12 is made of welded steel plate, and its internal dimensions match the external dimensions of the side mold or top mold 6, ensuring that the side mold or top mold 6 can be placed smoothly. A rubber pad 13 is fixedly connected inside the placement groove 12. The rubber pad 13 is made of highly elastic and wear-resistant rubber material. The upper surface of the rubber pad 13 is provided with a flared opening, which corresponds to the position of the flared opening 10 below the U-shaped frame 9, and plays a guiding role. In actual operation, when the lifting trolley 701 moves the side mold or top mold 6 to directly above the placement groove 12, the winding machine 702 begins to release the steel cable 703, causing the side mold or top mold 6 to descend slowly. During the descent, the side mold or top mold 6 can always be kept vertical by the guiding action of the U-shaped frame 9, avoiding tilting or deviation, so as to accurately and smoothly enter the interior of the placement groove 12. The rubber pad 13 can buffer and protect the descending side mold or top mold 6, preventing the side mold or top mold 6 from hard collision with the inner wall of the placement groove 12, preventing scratches, deformation and other damage to the mold surface, and also reducing noise during the placement process.
[0032] The U-shaped frame 9 is internally fixedly connected to a sleeve 14, and internally fixedly connected to a fixing ring 15. The inner wall of the fixing ring 15 is slidably connected to a slide rod 16. The fixing ring 15 has an air hole inside. The outer wall of the fixing ring 15 is fixedly connected to a tension spring 18. The other end of the tension spring 18 is fixedly connected to a baffle and a sealing gasket 17. The outer wall of the baffle and sealing gasket 17 is fixedly connected to the outer wall of the slide rod 16. The outer wall of the hanger 2 is fixedly connected to a limit plate 19. The end of the slide rod 16 away from the baffle and sealing gasket 17 is slidably connected to the outer wall of the limit plate 19.
[0033] Specifically, a sleeve 14 is fixedly connected inside the U-shaped frame 9, and a fixing ring 15 is fixedly connected inside the sleeve 14. The fixing ring 15 fits tightly against the inner wall of the sleeve 14. The sleeve 14 passes through the U-shaped frame 9 and the fixing frame 8 and communicates with the outside, providing a channel for air to enter and exit. A sliding rod 16 is slidably connected to the inner wall of the fixing ring 15. The sliding rod 16 is made of smooth stainless steel and can slide flexibly within the through hole of the fixing ring 15. Multiple air holes are opened inside the fixing ring 15, and the air holes are evenly distributed in the circumferential direction of the fixing ring 15 to realize air circulation between the inside and outside of the U-shaped frame 9. A tension spring 18 is fixedly connected to the outer wall of the fixing ring 15. The tension spring 18 is a high-strength spring with good elastic recovery ability. A baffle and a sealing gasket 17 are fixedly connected to the other end of the tension spring 18. The baffle is made of rigid material and the sealing gasket is made of elastic sealing material. The outer wall of the sealing gasket fits tightly against the inner wall of the U-shaped frame 9, which can seal the inside of the U-shaped frame 9. The outer wall of the baffle and sealing gasket 17 is fixedly connected to one end of the slide rod 16, and the other end of the slide rod 16 extends to the outside of the U-shaped frame 9. The outer wall of the hanger 2 is fixedly connected to the limiting plate 19, which has a wedge-shaped structure. The end of the slide rod 16 away from the baffle and sealing gasket 17 is slidably connected to the outer wall of the limiting plate 19. In specific operations, after the side mold or top mold 6 enters the interior of the U-shaped frame 9, the air above the U-shaped frame 9 is vented through the air pipe 11, so that a negative pressure environment is formed inside the U-shaped frame 9. Under the action of negative pressure, the side mold or top mold 6 can be firmly adsorbed inside the U-shaped frame 9, further ensuring the stability of the side mold or top mold 6 during suspension and transportation, and preventing it from shaking or falling off. When the trolley 701 moves the side mold or top mold 6 above the placement groove 12, the end of the slide rod 16 begins to contact the inclined surface of the limiting plate 19. Since the limiting plate 19 is fixed to the outer wall of the hanger 2, as the trolley 701 continues to move, the slide rod 16 is squeezed by the inclined surface of the limiting plate 19 and slides into the U-shaped frame 9. When the slide rod 16 slides, it pushes the baffle and sealing gasket 17 away from the inner wall of the U-shaped frame 9. At this time, the external air enters the interior of the U-shaped frame 9 through the air holes on the sleeve 14 and the fixing ring 15, so that the negative pressure environment inside the U-shaped frame 9 is released. Then the winding machine 702 releases the steel cable 703 and smoothly lowers the side mold or top mold 6 into the placement groove 12. When the trolley 701 moves the U-shaped frame 9 away from the placement slot 12, the slide bar 16 is no longer squeezed by the limiting plate 19, and the tension spring 18 rebounds under the action of elastic restoring force, causing the baffle and sealing gasket 17 to re-fit against the inner wall of the U-shaped frame 9, sealing the end of the sleeve 14 and ensuring the sealing of the inside of the U-shaped frame 9.
[0034] A bracket 20 is provided on one side of the track 1. A rotating shaft 21 is fixedly connected to the outer wall of the bracket 20. A rotating ring 22 is rotatably connected to the outer wall of the rotating shaft 21. A scraper 23 is fixedly connected to the outer wall of the rotating ring 22.
[0035] Specifically, a support 20 is provided on one side of the track 1, and the bottom of the support 20 is fixedly connected to the ground. A rotating shaft 21 is fixedly connected to the outer wall of the support 20, and its axis is horizontally set. A rotating ring 22 is rotatably connected to the outer wall of the rotating shaft 21, and the rotating ring 22 can rotate freely around the rotating shaft 21. A scraper 23 is fixedly connected to the outer wall of the rotating ring 22, and the end of the scraper 23 can closely fit the upper surface of the bottom mold 5. After the top mold and side mold are removed and the precast component is demolded, the moving trolley 3 can drive the bottom mold 5 and the formed precast component to move along the track 1, transferring the precast component to the storage area or the subsequent processing work area. After the moving trolley 3 moves the bottom mold 5 to transfer the precast components, the scraper 23 can be made to be horizontally attached to the upper surface of the bottom mold 5 by rotating the rotating ring 22. Then, the moving trolley 3 is controlled to continue moving along the track 1. During the movement, the scraper 23 slides relative to the upper surface of the bottom mold 5, which can completely peel off the concrete residue attached to the upper surface of the bottom mold 5, so as to avoid the residue from affecting the molding quality of the subsequent precast components.
[0036] A rack 24 is fixedly connected to the upper surface of the mobile trolley 3. A rotating shaft 27 is rotatably connected to the outer wall of the bracket 20. A spur gear 25 and a bevel gear 26 are fixedly connected to the outer wall of the rotating shaft 27. The tooth end of the spur gear 25 is meshed with the tooth end of the rack 24. The tooth end of the bevel gear 26 is meshed with the bevel gear 28. The outer wall of the bevel gear 28 is fixedly connected to the outer wall of the rotating ring 22.
[0037] Specifically, to achieve automatic rotation of the scraper 23 without manual intervention, two sets of racks 24 are symmetrically arranged on the upper surface of the moving trolley 3, with the two sets of racks 24 located on both sides of the bottom mold 5. A second rotating shaft 27 is rotatably connected to the outer wall of the support 20, and is parallel to the axis of the first rotating shaft 21. The support 20 provides stable support for the second rotating shaft 27, ensuring its flexible rotation. A spur gear 25 and a bevel gear 26 are fixedly connected to the outer wall of the second rotating shaft 27. The spur gear 25 meshes with the teeth of the rack 24, and the bevel gear 26 meshes with the teeth of the second bevel gear 28. The outer wall of the second bevel gear 28 is fixedly connected to the outer wall of the rotating ring 22, thus transmitting power. When the moving trolley 3 moves the bottom mold 5 to the precast component transfer area, the rack 24 slides accordingly. When the rack 24 slides, it drives the spur gear 25 that meshes with it to rotate. The spur gear 25 drives the bevel gear 26 to rotate synchronously through the second rotating shaft 27. When the bevel gear 26 rotates, it drives the bevel gear 28 that meshes with it to rotate. The bevel gear 28 then drives the rotating ring 22 to rotate around the first rotating shaft 21, and finally raises the scraper 23 to prevent the scraper 23 from colliding with the precast component during the transfer of the precast component from the bottom mold 5, which would cause damage to the component. After the bottom mold 5 transports the precast components to the destination and completes unloading, the moving trolley 3 drives the bottom mold 5 back. At this time, another set of racks 24 begins to mesh with the spur gear 25, causing the spur gear 25 to rotate in the opposite direction. The spur gear 25 drives the bevel gear 26 and bevel gear 28 to rotate in the opposite direction through the second rotating shaft 27, which in turn drives the rotating ring 22 to rotate in the opposite direction, so that the scraper 23 is horizontally attached to the upper surface of the bottom mold 5 again. At this time, the moving trolley 3 continues to move, and the scraper 23 can automatically peel off the residue on the upper surface of the bottom mold 5, realizing the automatic cleaning of the bottom mold 5.
[0038] A column 30 is provided on the other side of the hanger 2, and a limit baffle 29 is fixedly connected to the upper surface of the bracket 20.
[0039] Specifically, a column 30 is provided on the other side of the hanger 2. The bottom of the column 30 is fixedly connected to the ground to provide auxiliary support for the other end of the hanger 2. A limit baffle 29 is fixedly connected to the upper surface of the bracket 20. The limit baffle 29 is used to limit and support the scraper 23 after it is erected. A bidirectional torque limiter 33 is provided on the outer wall of the second rotating shaft 27. The bidirectional torque limiter 33 is fixedly connected to the outer wall of the bracket 20 and is coaxial with the second rotating shaft 27. It can limit and protect the rotation torque of the second rotating shaft 27. When the scraper 23 is lowered and adheres to the upper surface of the bottom mold 5, the column 30 provides stable support and fixation for the rotating shaft 27, preventing the scraper 23 from shaking during the cleaning process. When the scraper 23 is raised, the end of the scraper 23 rests on the outer wall of the limiting baffle 29. At this time, the bidirectional torque limiter 33 can slip when the scraper 23 is subjected to excessive force, preventing the transmission components such as the rotating shaft 27, the spur gear 25, and the rack 24 from being damaged due to excessive force, thus playing an overload protection role. Similarly, when the scraper 23 is lowered back to the upper surface of the bottom mold 5, the bidirectional torque limiter 33 can also play a role in stable support and overload protection, ensuring the operational safety and stability of the entire transmission mechanism.
[0040] Collection box 1 31 and collection box 2 32 are installed between the two tracks 1 on both sides.
[0041] Specifically, to achieve centralized collection of concrete residue, prevent residue from scattering and polluting the working environment, and facilitate subsequent cleaning and recycling, collection box one 31 and collection box two 32 are installed between the two side tracks 1. Collection box one 31 and collection box two 32 have open tops to facilitate residue falling into them. Collection box one 31 is located near the support 20 and directly below the bottom mold 5. When the scraper 23 removes residue from the upper surface of the bottom mold 5, the removed residue falls into the interior of collection box one 31 under gravity, achieving centralized collection of cleaning residue from the bottom mold 5. Collection box 2 32 is located near the placement slot 12. After the demolding operation is completed, the suspension mechanism 7 first lifts the side mold or top mold 6 to detach it from the precast component. Then, the lifting trolley 701 moves the side mold or top mold 6 to directly above the collection box 2 32. After that, the winding machine 702 further lifts the side mold or top mold 6 so that it enters the U-shaped frame 9. Under the combined action of the U-shaped frame 9 and the air pipe 11, the residue on the outer wall of the side mold or top mold 6 is peeled off. The peeled residue will fall into the interior of the collection box 2 32, realizing the centralized collection of the cleaning residue of the side mold or top mold 6, thereby realizing the classified collection of residue from different parts and improving the cleanliness of the working environment.
