Description

Technical Field

[0001] The invention relates to the technical field of recycled concrete prefabricated part production, in particular to a double-mold linkage demoulding workstation for producing recycled concrete prefabricated parts. Background Art

[0002] As demand for resource utilization of construction waste grows, recycled concrete, an environmentally friendly building material, can reduce construction waste and alleviate the shortage of natural resources by crushing, cleaning, and grading waste concrete to replace natural aggregates (mainly coarse aggregate). However, its actual engineering application faces the following technical bottlenecks:

[0003] 1. Insufficient strength. The chemical composition and microstructure of the old cement paste attached to the surface of the recycled aggregate differ significantly from those of the new paste, resulting in poor bonding in the interface transition zone. The pores and cracks in the old paste become stress concentration points, significantly reducing the compressive and flexural strength of the recycled concrete precast parts and limiting their application in high-strength engineering.

[0004] 2. Demolding is difficult and prone to damage. The high water absorption and rough surface of recycled aggregates create a strong mechanical bond with the formwork. Moisture migration causes the concrete surface near the formwork to dry out, further exacerbating adhesion. Existing demolding processes use conventional precast concrete (flipping and vibrating to separate). However, recycled concrete precast parts are weak and lack support during demolding. The impact of their own weight can easily lead to increased internal porosity and the expansion of microcracks, further degrading their strength and durability. Summary of the Invention

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] See also Figures 1-12 The present invention provides a technical solution: a double-mold linkage demoulding workstation for producing recycled concrete prefabricated parts, including a conveying mechanism 1 and a demoulding mechanism 2.

[0043] The conveying mechanism 1 includes an input portion 11, an output portion 12 and a demoulding portion 13;

[0044] There are two groups of demoulding mechanisms 2, and each group of demoulding mechanisms 2 includes:

[0045] The demoulding mechanism 2 is mounted on the demoulding portion 13 via the frame 21 , and a protrusion 22 is mounted in the frame 21 ;

[0046] The slider 23 is slidably mounted on the frame 21, and a wedge block 24 is elastically slidably mounted inside the slider 23. A lifting member 26 is elastically slidably mounted on the bottom of the slider 23 via a demoulding spring 25; Figure 7 In this embodiment, the wedge block 24 and the slider 23 are elastically slidably connected by a spring sheet provided between the slider 23 and the wedge block 24;

[0047] The clamping portion 3 includes a base 31, a pair of clamps 32, and a telescopic portion 38. The base 31 is rotatably mounted on the inner side of the slider 23, and the clamps 32 are disposed on both sides of the base 31. The telescopic portion 38 can drive the clamps 32 to alternately open and close. The clamps 32 are each equipped with a sensing element 5 and elastically connected to a lifting element 4. The lifting element 4 is used to lift the component. The sensing element 5 adjusts the lifting force of the lifting element 4 according to the gravity of the component.

[0048] The turning portion 6 is used to drive the base 31 to rotate;

[0049] The lifting part 7 is installed on the outside of the frame 21 and drives the slider 23 to move up and down through the lifting member 26. When the wedge block 24 contacts the protrusion 22, the movement of the slider 23 is restricted, and the demoulding spring 25 accumulates force. When the rebound force of the demoulding spring 25 overcomes the resistance of the protrusion 22, it can accelerate the movement of the slider 23, change the speed of the clamping part 3, and use inertia to separate the component from the mold.

[0050] For details, see Figure 1-Figure 3, place the mold to be demoulded on the conveying mechanism 1 with the mold opening facing upward to prevent the component from falling and causing damage to the component. The mold and the component move from the input part 11 of the conveying mechanism 1 to the demoulding part 13. When the mold moves to the left side of the demoulding part 13, the adjustment area, the lifting part 7 lifts the mold and the component through the clamping part 3. The gravity of the component and the mold is applied to the clamping part 3, the sensor 5 is triggered and adjusts the lifting force of the lifting part 4 on the component according to the gravity of the component and the mold;

[0051] After the lifting force of the lifting member 4 is adjusted, the turning part 6 rotates the mold from the left to the right, with the mold opening facing downward. At this time, the component is supported by the lifting member 4, and the component will not produce a large displacement with the mold under the action of gravity, thereby preventing the component from hitting the demoulding equipment and causing damage to the component;

[0052] After the mold is flipped, the lifting part 7 drives the lifting member 26 to drive the slider 23 to rise, and the wedge block 24 rises synchronously with the slider 23. When the wedge block 24 contacts the protrusion 22, the rise of the wedge block 24 is blocked and gradually shrinks into the slider 23, and the slider 23 stops rising. The demoulding spring 25 accumulates force until the wedge block 24 is completely retracted into the slider 23, and the slider 23 loses its limit. The demoulding spring 25 is released, and the slider 23 is accelerated to pop out. The slider 23 undergoes intermittent accelerated movement during the lifting process. During the lifting process of the slider 23, the clamp 32 is driven to rise and fall through the base 31, and the clamp 32 drives the mold to intermittently accelerate. The component is supported by the lifting member 4, which is elastically connected to the clamp 32. There is a hysteresis in the displacement of the component. Under the action of centrifugal force, the component can produce relative displacement with the mold, so that the mortar structure with adhesion between the component and the mold is destroyed, thereby reducing the displacement resistance between the component and the mold. At the same time, the component is supported by the lifting member 4 and cannot be completely separated from the mold. The lifting part 7 drives the slider 23 to descend, so that the component and the mold descend and fall onto the conveying mechanism 1. The component and the mold move from the demoulding part 13 to the output part 12. At this time, the mold can be directly taken out from the top of the component.

[0053] The present invention uses the coordinated control of elastic support and hysteresis displacement to enable the component to form a controllable relative slip with the mold during the demoulding process, effectively avoiding direct impact or severe vibration, and significantly reducing the risk of increased internal porosity and microcrack expansion caused by mechanical bite, gravity extrusion and surface adhesion, reducing the surface and internal damage rate of the component, and improving the qualified rate of finished products; at the same time, the energy storage-instantaneous release mechanism of the demoulding spring 25 is used to drive the intermittent accelerated movement of the mold, accurately destroying the mortar bonding layer between the component and the mold, avoiding secondary damage to the low-strength interface transition zone of the recycled concrete caused by traditional vibration demoulding, and is particularly suitable for highly absorbent and highly adhesive recycled aggregate systems; in addition, the lifting force of the lifting member 4 is adjusted according to the gravity of the component through the sensing member 5, the component quality is detected and the lifting force is adjusted in real time to ensure that the lifting force is always in the "critical peeling range", which not only avoids component collision due to insufficient lifting force, but also prevents excessive lifting force from inhibiting relative displacement, thereby achieving precise adaptation of the demoulding mechanics.

[0054] As a further embodiment of the present invention, the clamp 32 includes a pair of supporting plates 33, a sensing plate 34, and a synchronous gear 35; the supporting plates 33 and the sensing plates 34 are both L-shaped and elastically slidably provided with a buffer plate 36. In this embodiment, a spring plate is installed on the buffer plate 36 to achieve elastic sliding connection between the buffer plate 36 and the supporting plates 33 and the sensing plates 34; the synchronous gear 35 is rotatably disposed in the base 31 and is engaged with a synchronous rack 37. The synchronous racks 37 are in pairs and are fixed to the supporting plates 33 and the sensing plates 34 respectively; the telescopic portion 38 drives the diagonal supporting plates 33 and the sensing plates 34 to move in the same direction, thereby driving the clamp 32 to open and close alternately;

[0055] For details, see Figure 6 and Figure 7 Taking the single-sided clamp 32 as an example, its clamping action is achieved through the following linkage mechanism:

[0056] The telescopic portion 38 drives the supporting plate 33 to move axially, and the supporting plate 33 synchronously drives the synchronous rack 37 rigidly connected to it to translate; the synchronous rack 37 engages to drive the synchronous gear 35 to rotate, and then through the reverse translation of the synchronous rack 37 on the other side, the two synchronous racks 37 move in opposite directions, driving the sensing plate 34 and the supporting plate 33 to move towards or away in opposite directions, thereby realizing the clamping or loosening action of the clamp 32.

[0057] 32-way coordinated control of double-sided fixtures:

[0058] like Figure 6 As shown, the supporting plates 33 of the two side clamps 32 are arranged in opposite directions. When the telescopic portion 38 drives the supporting plates 33 to move in the same direction, the two side clamps 32 form an alternating "opening and closing" movement: when the left clamp 32 opens, the right clamp 32 closes. This design allows the clamps 32 to form a dynamic connection between the demoulding and loading processes, for example:

[0059] Demolding and loading are carried out in parallel: when the first mold is turned over, the left clamp 32 is in the open state, and the new mold and component can be synchronously transported into the clamping position through the input part 11;

[0060] The lifting and demoulding are synchronized: when the lifting part 7 drives the clamp 32 to rise, the right clamp 32 performs the demoulding operation, and the left clamp 32 simultaneously lifts the new mold and the component, and the sensing part 5 adjusts the lifting force of the lifting part 4 according to the gravity of the component to ensure that the lifting force is accurately matched with the quality of the component; through the alternating opening and closing of the double-sided clamps 32 and the adjustment of the lifting force one by one according to the gravity of the component, the demoulding, loading and lifting force adjustment processes are parallelized, shortening the batch demoulding cycle and significantly improving production efficiency and process stability.

[0061] As a further solution of the present invention, the lifting member 4 includes:

[0062] The bottom plate 41 is installed in the carrier plate 33;

[0063] The limiting frame 42 is fixed on the bottom plate 41;

[0064] A lifting frame 43 is elastically slidably disposed on the limiting frame 42, and the lifting frame 43 abuts against the bottom of the component;

[0065] For details, see Figure 8 When the clamp 32 moves toward the component, the lifting frame 43 contacts the bottom of the component, and the lifting frame 43 stops moving relative to the component. The clamp 32 continues to approach the mold, and the lifting spring 45 is compressed and contracts and stores energy until the lifting frame 43 is flush with the bearing plate 33. At this time, the preload of the lifting spring 45 is balanced with the gravity of the component.

[0066] When the component and the mold are relatively displaced due to the demoulding force, the lifting spring 45 is further compressed, absorbing the displacement energy of the component through elastic deformation. At the same time, the reaction force of the lifting spring 45 increases linearly with the increase in compression, forming a dynamic match of "displacement-supporting force":

[0067] As a further solution of the present invention, the bottom plate 41 is threadedly connected to a pressure-adjusting bolt 44 , and a lifting spring 45 is provided between the pressure-adjusting bolt 44 and the lifting frame 43 ;

[0068] See also Figure 4 and Figure 5When the pressure-adjusting bolt 44 is rotated clockwise, the initial compression of the lifting spring 45 increases, the preload increases linearly, and the effective working stroke of the spring is shortened; when the pressure-adjusting bolt 44 is rotated counterclockwise, the initial compression of the lifting spring 45 decreases, the preload decreases, and the effective working stroke of the spring is extended, providing more space for subsequent elastic deformation; by adjusting the preload, the initial lifting force of the lifting member 4 can be changed to adapt to concrete components of different densities; during the demolding process, the elastic deformation of the lifting spring 45 is superimposed on the preload to form a composite supporting mode of "preload + dynamic deformation", ensuring that low-density components such as foam concrete are not overloaded during demolding, and high-density components such as barite concrete do not lose stability during demolding.

[0069] As a further solution of the present invention, the induction member 5 includes:

[0070] The sensing airbag 51 and the lifting airbag 52 are installed between the sensing plate 34 and the buffer plate 36; the lifting airbag 52 is installed between the bearing plate 33 and the bottom plate 41;

[0071] The connecting portion 53 is mounted on the ends of the sensing plate 34 and the supporting plate 33 and is in communication with the sensing airbag 51 and the lifting airbag 52, respectively. The connecting portion 53 is provided with a through hole 54 and is elastically and slidably provided with a gate 55. The gate 55 is fixed with a trigger member 57 that can contact the base 31. The base 31 is provided with a connecting tube 56 that can communicate with the through hole 54. In this embodiment, the elastic member is a spring and is provided between the trigger member 57 and the slide rod. The slide rod is fixed to the connecting portion 53.

[0072] It should be noted that, see Figure 11 , a vertical rod is installed on the connecting portion 53, and a spring is provided between the vertical rod and the trigger member 57. Since the trigger member 57 is fixed to the gate 55, the gate 55 is elastically slidable relative to the connecting portion 53;

[0073] For details, see Figure 8 、 Figure 9 and Figure 10When the supporting plate 33 and the sensing plate 34 move away from each other and move to the limit, the triggering member 57 contacts the base 31, causing the gate 55 installed in the connecting portion 53 to move, the through hole 54 is opened, and the connecting portion 53 is connected to the connecting pipe 56 through the through hole 54, the sensing airbag 51 is connected to the lifting airbag 52, and the internal air pressure of the sensing airbag 51 and the lifting airbag 52 is quickly balanced. The sensing plate 34 rises and contacts the mold to lift the mold. The weight of the mold and the component is applied to the sensing airbag 51 through the buffer plate 36. 1 contracts and the internal gas moves into the lifting airbag 52, causing the lifting airbag 52 to expand; as the lifting airbag 52 expands, the bottom plate 41 drives the limiting frame 42 and the pressure-adjusting bolt 44 to move toward the component, and the pressure-adjusting bolt 44 drives the limiting frame 42 to move through the lifting spring 45. The limiting frame 42 is displaced synchronously, so that the initial position of the lifting spring 45 remains unchanged. By changing the displacement range of the lifting frame 43, the lifting force on the clamped component is adjusted, thereby adjusting the lifting force of the lifting member 4 according to the gravity of the component.

[0074] As a further solution of the present invention, the lifting part 7 includes a lifting motor 71 mounted on the frame 21, and the output shaft of the lifting motor 71 is fixed with a screw 72, which is threadedly connected to the lifting member 26;

[0075] Specifically, the lifting motor 71 drives the screw 72 to rotate through the output shaft, the screw 72 drives the slider 23 to move up and down through the lifting member 26 threadedly connected thereto, and the slider 23 drives the clamp 32 to move up and down through the base 31, thereby realizing the lifting of the component and the mold.

[0076] As a further solution of the present invention, the flipping part 6 includes a flipping motor 61 , the output shaft of which is fixed on the base 31 ; the flipping motor 61 is sleeved with the screw 72 through the base 62 .
