Description

Technical Field

[0001] The present invention relates to the technical field of the production of recycled concrete precast components, and particularly to a dual-mode linkage demoulding workstation for the production of recycled concrete precast components. Background Art

[0002] With the increasing demand for the resource utilization of construction waste, recycled concrete, as an environmentally friendly building material, is made by crushing, cleaning, and grading waste concrete and then replacing natural aggregates (mainly coarse aggregates), which can reduce construction waste and alleviate the shortage of natural resources. However, there are the following technical bottlenecks in its actual engineering applications: 1. Insufficient strength performance. The old cement paste attached to the surface of recycled aggregates has significant differences in chemical composition and microstructure from the new paste, resulting in poor bonding performance in the interfacial transition zone. The pores and cracks in the old paste become stress concentration points, significantly reducing the compressive and flexural strengths of recycled concrete precast components and restricting their application in high-strength projects.

[0003] 2. Difficult demoulding and easy damage. The high water absorption and rough surface characteristics of recycled aggregates result in a strong mechanical bite with the formwork, and the moisture migration causes the concrete surface near the formwork to dry easily, further exacerbating the adhesion. The existing demoulding process follows the method for ordinary concrete precast components (vibrating and separating after flipping), but the recycled concrete precast components have low strength and lack support during demoulding, and are prone to the impact of their own gravity, resulting in an increase in internal pores and the expansion of microcracks, exacerbating the deterioration of strength and durability. Summary of the Invention

Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0016] Please refer to Figures 1 - 12 , the present invention provides a technical solution: a double-mode linkage demolding workstation for manufacturing recycled concrete precast components, including a conveying mechanism 1 and a demolding mechanism 2.

[0017] The conveying mechanism 1 includes an input part 11, an output part 12 and a demolding part 13; There are two sets of demolding mechanisms 2, and each set of demolding mechanisms 2 includes: A frame 21, the demolding mechanism 2 is installed on the demolding part 13 through the frame 21, and a convex block 22 is installed inside the frame 21; A slider 23, slidably arranged on the frame 21, with a wedge block 24 elastically slidably installed inside it, and a lifting member 26 is elastically slidably installed at the bottom of the slider 23 through a demolding spring 25; Refer to Figure 7 , in this embodiment, through the spring piece arranged between the slider 23 and the wedge block 24, the elastic sliding connection between the wedge block 24 and the slider 23 is realized; The clamping part 3 includes a base 31, a pair of clamps 32 and a telescopic part 38; the base 31 is rotatably arranged inside the slider 23, the clamps 32 are respectively arranged on both sides of the base 31, and the telescopic part 38 can drive the clamps 32 to open and close alternately; induction parts 5 are installed on both of the clamps 32 and are elastically connected with a lifting part 4, the lifting part 4 is used for lifting the component, and the induction part 5 adjusts the lifting force of the lifting part 4 according to the gravity of the component; The flipping part 6 is used to drive the base 31 to rotate; The lifting part 7 is installed outside the frame 21 and drives the slider 23 to lift through a lifting member 26; when the wedge block 24 abuts against the convex block 22, the movement of the slider 23 is restricted, and the demolding spring 25 stores energy. When the resilience of the demolding spring 25 overcomes the resistance of the convex block 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; Specifically, refer to Figures 1 - 3 , place the mold to be demolded on the conveying mechanism 1 with the opening side of the mold facing upward to prevent the component from falling and being damaged. The mold and the component move from the input part 11 of the conveying mechanism 1 to the demolding part 13. When the mold moves to the adjustment area on the left side of the demolding part 13, the lifting part 7 jacks up 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, and the induction part 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; After the lifting force of the lifting part 4 is adjusted, the flipping part 6 rotates the mold from the left side to the right side, and the opening side of the mold faces downward. At this time, the component is lifted by the lifting part 4, and the component will not have a large displacement from the mold under the action of gravity, thereby avoiding the component hitting the demolding equipment and causing damage to the component; After the mold is flipped, the lifting part 7 drives the lifting member 26 to drive the slider 23 to rise. The wedge block 24 rises synchronously with the slider 23. When the wedge block 24 contacts the convex block 22, the rising of the wedge block 24 is blocked and it gradually contracts into the slider 23. The slider 23 stops rising, and the demolding spring 25 stores energy until the wedge block 24 completely contracts into the slider 23. The slider 23 loses its limit, the demolding spring 25 releases, and the slider 23 accelerates and pops out. During the lifting and lowering process of the slider 23, it undergoes intermittent acceleration. During the lifting and lowering process of the slider 23, the base 31 drives the clamps 32 to lift and lower, and the clamps 32 drive the mold to undergo intermittent acceleration. The component is lifted by the lifting part 4, and the lifting part 4 and the clamps 32 are elastically connected. There is a lag in the displacement of the component. Under the action of centrifugal force, a relative displacement can be generated between the component and the mold, damaging the mortar structure adhering between the component and the mold, thereby reducing the displacement resistance between the component and the mold; at the same time, the component is lifted by the lifting part 4 and cannot completely separate from the mold; the lifting part 7 drives the slider 23 to lower, so that the component and the mold descend and land on the conveying mechanism 1. The component and the mold move from the demolding part 13 to the output part 12. At this time, the mold can be directly taken out from the top of the component; Through the coordinated control of elastic lifting and hysteretic displacement, the present invention enables the component to form a controllable relative slip with the mold during the demolding process, effectively avoiding direct impact or severe vibration, significantly reducing the risk of increased internal porosity and microcrack propagation caused by mechanical occlusion, gravity extrusion, and surface adhesion, reducing the damage rate of the component surface and interior, and improving the finished product qualification rate. At the same time, the energy storage - instantaneous release mechanism of the demolding spring 25 is used to drive the intermittent acceleration movement of the mold, precisely destroying the mortar bonding layer between the component and the mold, avoiding secondary damage to the low - strength interfacial transition zone of recycled concrete by traditional vibration demolding, and is particularly suitable for high - water - absorption and high - adhesion recycled aggregate systems. In addition, the sensing member 5 adjusts the lifting force of the lifting member 4 according to the gravity of the component, detects the quality of the component and adjusts the lifting force in real time, ensuring that the lifting force is always in the "critical peeling range", which not only avoids the impact of the component due to insufficient lifting force but also prevents excessive lifting force from inhibiting relative displacement, achieving precise adaptation of demolding mechanics.

[0018] As a further aspect of the present invention, the fixture 32 includes a pair of bearing plates 33, induction plates 34, and synchronous gears 35 arranged in pairs. Both the bearing plates 33 and the induction plates 34 are L - shaped, and buffer plates 36 are elastically slidably arranged thereon. In this embodiment, a spring plate is installed on the buffer plate 36 to achieve the elastic sliding connection between the buffer plate 36 and the bearing plates 33 and the induction plates 34. The synchronous gears 35 are rotatably arranged in the base 31 and are engaged with synchronous racks 37. The number of synchronous racks 37 is in pairs, and they are respectively fixed to the bearing plates 33 and the induction plates 34. The telescopic part 38 drives the diagonal bearing plates 33 and induction plates 34 to move in the same direction, realizing the alternate opening and closing of the fixture 32. Specifically, referring to Figure 6 and Figure 7 , taking the unilateral fixture 32 as an example, its clamping action is realized through the following linkage mechanism: The telescopic part 38 drives the bearing plate 33 to move axially, and the bearing plate 33 synchronously drives the synchronous rack 37 rigidly connected to it to translate. The synchronous rack 37 meshes with and drives 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), drives the induction plate 34 to approach or move away from the bearing plate 33 in the opposite direction, realizing the clamping or loosening action of the fixture 32.

[0019] Coordinated control of the bilateral fixture 32: As Figure 6 shown, the bearing plates 33 of the two - side fixtures 32 are arranged in the opposite direction. When the telescopic part 38 drives the bearing plates 33 to move in the same direction, the two - side fixtures 32 form an alternating movement of "one opening and one closing": when the left - side fixture 32 opens, the right - side fixture 32 closes. This design enables the fixture 32 to form a dynamic connection between the demolding and feeding processes. For example: Demoulding and loading are parallel: When the first mould is flipped, the left clamp 32 is in an open state. At this time, new moulds and components can be synchronously conveyed into the clamping position through the input part 11. Lifting and demoulding are synchronous: 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 jacks up the new mould 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 precisely matches the mass of the component; Through the alternating opening and closing of the bilateral clamps 32 and the adjustment of the lifting force one by one according to the gravity of the component, the parallel processing of the demoulding, loading, and lifting force adjustment processes is realized, shortening the batch demoulding cycle and significantly improving the production efficiency and process stability.

[0020] As a further solution of the present invention, the lifting part 4 includes: A bottom plate 41, which is installed in the bearing plate 33; A limiting frame 42, which is fixedly arranged on the bottom plate 41; A lifting frame 43, which is elastically slidably arranged on the limiting frame 42, and the lifting frame 43 abuts against the bottom of the component; Specifically, refer to Figure 8 , when the clamp 32 moves towards the component, the lifting frame 43 abuts against the bottom of the component, and the lifting frame 43 stops moving relative to the component. The clamp 32 continues to approach the mould, and the lifting spring 45 is compressed and stores energy until the lifting frame 43 is flush with the bearing plate 33. At this time, the pre-pressure of the lifting spring 45 is balanced with the gravity of the component; When the component and the mould produce relative displacement due to the demoulding force, the lifting spring 45 is further compressed, and the displacement energy of the component is absorbed through elastic deformation. At the same time, the reaction force of the lifting spring 45 increases linearly with the increase of the compression amount, forming a dynamic matching of "displacement - supporting force": As a further solution of the present invention, the bottom plate 41 is threadedly connected with a pressure regulating bolt 44, and a lifting spring 45 is arranged between the pressure regulating bolt 44 and the lifting frame 43; Refer to Figure 4 and Figure 5 , when the pressure regulating bolt 44 is rotated clockwise, the initial compression amount of the lifting spring 45 increases, the pre-pressure linearly increases, and at the same time the effective working stroke of the spring shortens; when the pressure regulating bolt 44 is rotated counterclockwise, the initial compression amount of the lifting spring 45 decreases, the pre-pressure decreases, and the effective working stroke of the spring extends, providing more space for subsequent elastic deformation; Through the pre-pressure adjustment, the initial lifting force of the lifting part 4 can be changed to adapt to concrete components with different densities; During the demoulding process, the elastic deformation and pre-pressure of the lifting spring 45 are superimposed to form a composite supporting mode of "pre-pressure + dynamic deformation", ensuring that low-density components such as foam concrete are not overloaded during demoulding, and high-density components such as barite concrete are not unstable during demoulding.

[0021] As a further solution of the present invention, the sensing part 5 includes: The sensing airbag 51 and the jacking airbag 52, the sensing airbag 51 is installed between the sensing plate 34 and the buffer plate 36; the jacking airbag 52 is installed between the bearing plate 33 and the bottom plate 41; The connecting part 53, the connecting part 53 is installed at the end of the sensing plate 34 and the bearing plate 33, and the connecting part 53 is respectively communicated with the sensing airbag 51 and the jacking airbag 52; a through hole 54 is opened in the connecting part 53, a gate plate 55 is elastically slidably arranged in the connecting part 53, and a trigger 57 capable of abutting against the base 31 is fixedly arranged on the gate plate 55; a connecting pipe 56 capable of communicating with the through hole 54 is arranged on the base 31. In this embodiment, the elastic member is a spring and is arranged between the trigger 57 and the sliding rod, and the sliding rod is fixedly arranged on the connecting part 53; It should be noted that referring to Figure 11 , a vertical rod is installed on the connecting part 53, and a spring is arranged between the vertical rod and the trigger 57. Since the trigger 57 is fixedly arranged with the gate plate 55, the gate plate 55 is elastically slidably arranged relative to the connecting part 53; Specifically, referring to Figure 8 、 Figure 9 and Figure 10 , when the bearing plate 33 and the sensing plate 34 move away from each other and reach the limit, the trigger 57 abuts against the base 31, causing the displacement of the gate plate 55 installed in the connecting part 53, the through hole 54 is opened, and the connecting part 53 is communicated with the connecting pipe 56 through the through hole 54, the sensing airbag 51 is communicated with the jacking airbag 52, the internal air pressures of the sensing airbag 51 and the jacking airbag 52 are quickly balanced, the sensing plate 34 rises and abuts against the mold to lift the mold, the weights of the mold and the component are applied to the sensing airbag 51 through the buffer plate 36, the sensing airbag 51 contracts and the internal gas moves into the jacking airbag 52, causing the jacking airbag 52 to expand; as the jacking airbag 52 expands, the bottom plate 41 drives the limit frame 42 and the pressure regulating bolt 44 to move towards the component direction, the pressure regulating bolt 44 drives the limit frame 42 to move through the lifting spring 45, the limit frame 42 displaces synchronously, so that the initial state position of the lifting spring 45 remains the same, and by changing the displacement range of the lifting frame 43, the lifting force received by the clamped component is adjusted, and the lifting force of the lifting member 4 is adjusted according to the gravity of the component.

[0022] As a further solution of the present invention, the lifting part 7 includes a lifting motor 71 installed on the frame 21, and a screw rod 72 is fixedly arranged on the output shaft of the lifting motor 71, and the screw rod 72 is threadedly connected with the lifting member 26; Specifically, the lifting motor 71 drives the screw rod 72 to rotate through the output shaft, the screw rod 72 drives the lifting member 26 to lift the slider 23 through the threaded connection therewith, and the slider 23 drives the fixture 32 to lift through the base 31, so as to realize the lifting of the component and the mold.

[0023] As a further solution of the present invention, the flipping part 6 includes a flipping motor 61, and the output shaft of the flipping motor 61 is fixedly arranged on the base 31; the flipping motor 61 is sleeved with a screw rod 72 through a machine base 62.
