Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated beam demoulding equipment, and in particular to assembled prefabricated beam demoulding equipment and a prefabricated demoulding process. Background Art

[0002] Prefabricated beams are concrete beams prefabricated in a factory and then installed on-site. These beams, typically composed of steel and concrete, are standardized and mass-produced, significantly improving construction efficiency and quality. They offer advantages such as standardized production, improved construction efficiency, reduced labor intensity, enhanced quality control, and energy conservation and environmental protection. After manufacturing, prefabricated beams require disassembly of the molds used to create them before they can be removed for assembly. Prefabricated beams are energy-efficient building materials, and the molds used to create them are also specialized equipment for their production.

[0003] For example, the Chinese utility model patent application number: 202222771389.2, entitled Precast Beam Demolding Device, discloses a precast beam demolding device; it includes a rod body with a hook at one end, and a fixed plate, a movable plate, an inertia hammer and a limiting plate are sequentially arranged on the rod body, the fixed plate and the limiting plate are fixedly connected to the rod body, the movable plate and the inertia hammer are slidably connected to the rod body, and the rod body is also fixedly connected to a telescopic rod; an elastic part is arranged between the fixed plate and the movable plate, the telescopic end of the telescopic rod is fixedly connected to an electromagnet part that absorbs the inertia hammer, and the fixed plate is provided with a magnetic part that is magnetically attracted to the inertia hammer; when in use, the inertia hammer is repeatedly struck against the limiting plate by the telescopic rod and the electromagnet part thereon, and the kinetic energy generated during the impact is transferred to the mold through the limiting plate fixedly connected to the rod body, thereby separating the mold from the component and completing the demolding process, with good demolding effect, and no manual control of the inertia hammer is required, which is more efficient and safer.

[0004] The shortcomings of the existing technology are that: when the precast beam is disassembled, a lifting equipment is needed to assist in separating the mold from the formed precast beam. For example, in the above-mentioned patent, the mold is lifted by the lifting equipment and then hit by the inertia hammer set on the lifting rod body, so that the mold is separated from the precast beam and lifted. First, the hitting area of the inertia hammer set on the lifting rod hook is limited, and this disassembly method can only disassemble the mold on the side of the precast beam, and it is difficult to separate the precast beam from the bottom mold plate. Therefore, after the operation, the precast beam needs to be lifted and rotated to separate the bottom mold from the precast beam. When the precast beam is lifted, the precast beam and the bottom mold are tightly fitted, causing the binding strap to pass through the appropriate position on the precast beam. It can only be fixed on the steel bars at both ends of the precast beam. The precast beam is heavy, and it is easy to fall off when it is fixed on the steel bars for lifting, which is dangerous.

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0045] See also Figure 1-10The present embodiment provides an assembled prefabricated beam demoulding device, including a cantilever crane 1 and two frames 11. The cantilever crane 1 is an existing truss structure suspension device, mainly composed of a crane frame 11, a walking mechanism, a lifting mechanism and an electrical control system. It also includes a concave bottom template 12, two end templates, two side templates 13 and multiple sets of cross templates 14 fixed on the two side templates 13. Each cross template 14 is respectively adapted to the groove on the concave bottom template 12. The concave bottom template 12, the two end templates, the two side templates 13 and the multiple sets of cross templates 14 can form a complete prefabricated beam forming mold structure; each frame 11 is equipped with a demoulding template 15 through a connecting component, and the demolition template 15 is connected to the corresponding side template 13 through a detachable lock buckle 16. By setting the lock buckle 16, it is convenient to disassemble, replace or perform other operations on the demolition template 15, and it has strong flexibility; it also includes two sets of striking components and The two tooth plates 17 are on the corresponding frames 11, and the tooth plates 17 are driven by an external driving source. They work synchronously with the cantilever crane 1, so that the cantilever crane 1 releases the hook device and simultaneously triggers the demoulding of the formed precast beam, reducing the waiting time between devices and optimizing the demoulding stroke of the precast beam mold; when demoulding, the tooth plates 17 move down to trigger the striking component to strike the side template 13 back and forth to demould, and then trigger the connecting component to drive the demoulding template 15 to pull the side template 13 and the cross template 14 to separate from the precast beam, so that a gap is formed between the precast beam and the concave bottom template 12, which is convenient for the lifting parts on the cantilever crane 1 to pass through the gap and lift the precast beam body from the concave bottom template 12. Through the setting of the cross template 14, it is convenient to remove the side template 13 and leave a position for the binding strap on the precast beam body, which is convenient for the later suspension, lifting and demoulding of the precast beam, thereby improving the safety of the precast beam during demoulding.

[0046] In an embodiment further provided by the present invention, the connecting assembly includes a bidirectional reciprocating screw 21 rotatably connected to the frame 11, and a plurality of groups of threaded blocks 22 are provided on the bidirectional reciprocating screw 21. A rotating bar 23 is provided between each threaded block 22 and the demolition template 15. The threaded block 22 slides on the frame 11, and the frame 11 can limit the movement of the threaded block 22 to prevent it from rotating with the rotation of the bidirectional reciprocating screw 21. The rotating bar 23 is rotatably connected to the threaded block 22 and the demolition template 15, and the two adjacent rotating plates are symmetrically distributed. By providing multiple groups of rotating bars 23, the lateral movement of the demolition template 15 can be restricted.

[0047] Furthermore, the striking assembly includes a top plate 31 that slides vertically on the frame 11, a sliding plate 32 is connected to the top plate 31 for horizontal sliding, a moving frame 33 is fixedly connected to the sliding plate 32, and a plurality of groups of U-shaped striking frames 34 are slidingly connected to the dismantling template 15, each U-shaped striking frame 34 is connected to the moving frame 33 through a rotating bar 2 35, and the opening height set on the moving frame 33 is consistent with the height of the plurality of rotating bars 1 23, so as to avoid interference in the movement between the moving frame 33 and the rotating bar 1 23.

[0048] Furthermore, a power assembly that drives the top plate 31 to work is provided on the frame 11, and the power assembly includes a passive rod 41 rotatably connected to the frame 11, and a cam 42 and a gear 43 are fixedly connected to the passive rod 41. The top plate 31 slides on the cam 42 through a connecting rod, and the tooth plate 17 engages with the gear 43 during the movement of the tooth plate 17. A groove identical to the cam 42 is provided on the cam 42, and the connecting rod on the top plate 31 cooperates with the groove provided on the cam 42 so that when the cam 42 rotates, the top plate 31 can be driven to move back and forth, and the reciprocating motion of the top plate 31 drives the striking assembly to work and knock and demould the opposite side template 13.

[0049] In an embodiment further provided by the present invention, a transmission assembly is provided on the frame 11, and the transmission assembly includes a synchronization rod 51 and an auxiliary rod 52 rotatably connected to the frame 11. The synchronization rod 51 is transmission-connected to the bidirectional reciprocating screw rod 21 through a belt 53. The synchronization rod 51 and the auxiliary rod 52 are both provided with a gear 2 54 through a one-way assembly. The bidirectional reciprocating screw rod 21 is provided with a gear 3 55. The auxiliary rod 52 is fixedly connected with a gear 4 56 meshing with the gear 3 55. The synchronization rod 51 and the reciprocating screw rod are both provided with a sprocket adapted to the belt 53. In addition, the synchronization rod 51, the passive rod 41, the reciprocating screw rod and the auxiliary rod 52 are arranged in sequence from top to bottom. The arrangement of the synchronization rod 51, the auxiliary rod 52, the one-way component, the gear 2 54 and other structures is to facilitate the striking component to first strike the demolition template 15 and then pull the side template 13 to move. When it is reset, it first strikes the side template 13 so that the attached particles can fall away from the prefabricated beam manufacturing area, and then push the side template 13 to reset and splice with the concave bottom template 12, and finally fix the end template at both ends of the combination and then completely splice it.

[0050] In the embodiment provided by the present invention, the one-way component includes a ratchet plate 61, and a ratchet block 62 is connected to the gear 2 54 by a spring sliding connection. The elastic force of the spring drives the ratchet block 62 to engage with the ratchet plate 61. The one-way component located in the synchronization rod 51 and the one-way component located in the auxiliary rod 52 rotate at opposite angles. When the tooth plate 17 moves downward, it first contacts the gear 2 54 on the synchronization rod 51. At this time, the gear 2 54 on the synchronization rod 51 slips under the action of the one-way component without driving the synchronization rod 51 to rotate. When the tooth plate 17 moves to the maximum When the bottom is in contact with the gear 2 54 on the auxiliary rod 52, the gear 2 54 on the auxiliary rod 52 drives the auxiliary rod 52 to rotate under the action of the one-way component, and the connecting component is adjusted to remove the demolding template 15. On the contrary, the tooth plate 17 moves up, the gear 2 54 on the auxiliary rod 52 slips, the gear 2 54 on the synchronization rod 51 drives the synchronization rod 51 to rotate, and drives the connection component to open, reset and re-form through the belt 53. It is necessary to ensure that the length of the teeth on the tooth plate 17 is less than the distance between the synchronization rod 51 and the auxiliary rod 52.

[0051] Specifically, the gear 2 54 is also provided with a disassembly unit, which includes a plurality of wedge block rods 71 slidably connected to the gear 2 54, and a wedge groove 72 adapted to the wedge block is opened in each ratchet block 62, and the other end of the plurality of wedge block rods 71 is fixedly connected to the same connecting plate 73; the gear 2 54 is also fixedly connected to a locking member, which includes a threaded plate 81 fixed to the gear 2 54, and a screw 82 and a base 83 are provided on the threaded plate 81, the screw 82 is rotatably connected to the base 83, and a connecting strip 84 is provided between the base 83 and the connecting plate 73; each wedge block rod 71 is also provided with a positioning member The positioning rod includes an oblique groove 91 provided on the wedge block rod 71, and an L-shaped positioning rod 92 is slidably connected to the oblique groove 91. An annular groove 93 is provided on the auxiliary rod 52 and the synchronous rod 51, and each L-shaped positioning rod 92 is slidably connected to the corresponding annular groove 93. The disassembly unit, the locking member and the positioning member are provided to facilitate the disassembly and replacement of the gear 2 54 on the synchronous rod 51 and the auxiliary rod 52. Because the ratchet block 62 in the gear 2 54 is driven by a spring, it is easy to be damaged after long-term use, resulting in the inability to operate the equipment. Through the setting of this device, the gear 2 54 can be replaced when necessary.

[0052] A process for dismantling the prefabricated beams based on the above-mentioned prefabricated beams specifically includes the following steps:

[0053] S1: Move the cantilever crane 1 and the frame 11 to the precast beam to be demolded, connect the demolding plate 15 to the side plate 13 through the lock 16, start the cantilever crane 1 and the tooth plate 17 to move downward synchronously, the tooth plate 17 triggers the striking assembly to strike the side plate 13 to demold, and then pull the side plate 13 and the cross plate 14 to separate from the concave bottom plate 12 and the precast beam through the connecting assembly;

[0054] S2: Wrap the binding belt around the upper body of the precast beam through the gap of the horizontal template 14, and hang it on the cantilever beam crane 1 to lift it out of the mold;

[0055] S3: While the cantilever beam crane 1 is lifting, the tooth plate 17 moves up until the precast beam moves up to a certain height, and then the side template 13 and the horizontal template 14 are reset and spliced with the concave bottom template 12 and the templates at both ends to form a precast beam mold for casting again.

[0056] During operation, the cantilever crane 1 is moved to the side template 13 of the precast beam to be demoulded, and the lock buckle 16 on the demoulding template 15 is used to connect the demoulding template 15 with the side template 13. When demoulding, the cantilever crane 1 releases the hook at the same time, and the external driving source drives the toothed plate 17 to move downward synchronously. The toothed plate 17 moves downward and first contacts the gear 2 54 on the synchronization rod 51. Since the ratchet block 62 in the gear 2 54 cooperates with the ratchet plate 61 on the synchronization rod 51, the gear 2 54 is driven to slip on the synchronization rod 51 without driving the synchronization rod 51 to rotate. At this time, the toothed plate 17 continues to The cam 42 provided on the passive rod 41 moves downward, contacts the gear 1 43 on the passive rod 41, and drives the gear 1 43 to drive the passive rod 41 to rotate. At this time, the cam 42 provided on the passive rod 41 drives the top plate 31 to move up and down reciprocatingly with the rotation of the cam 42 under the action of the groove provided on it and the connecting rod on the top plate 31. The top plate 31 moves upward and drives the moving frame 33 to move synchronously through the sliding plate 32. The moving frame 33 moves up and down and drives the U-shaped striking frame 34 sliding in the demoulding template 15 to move back and forth laterally through the rotating bar 2 35 to knock the opposite side template 13 to demould;

[0057] Until the tooth plate 17 moves and contacts the gear 2 54 on the auxiliary rod 52, the ratchet block 62 in the gear 2 54 and the ratchet plate 61 block each other, so that the rotation of the gear 2 54 drives the auxiliary rod 52 to rotate synchronously, and the auxiliary rod 52 rotates through the gear 4 56 provided thereon to mesh with the gear 3 55 on the two-way reciprocating screw rod 21, so that the rotation of the two-way reciprocating screw rod 21 drives the threaded blocks 22 sliding on the frame 11 to move away from each other, and drives the stripping template 15 and the side template 13 and the cross template 14 locked on the stripping template 15 to be removed from the formed precast beam through the rotating bar 1 23. At this time, the space between the cross template 14 and the precast beam and the concave bottom template 12 is exposed, which is convenient for the operator to wrap the fixing belt and cooperate with the cantilever beam crane 1 for hanging, so as to realize the demoulding operation of the precast beam and the concave bottom template 12;

[0058] When the ratchet block 62 in the tooth plate 172 has been used for a period of time, the spring may fail. At this time, the screw 82 on the threaded plate 81 can be turned to move the base 83 downward, and the connecting strip 84 can be used to make the wedge block rod 71 close to the inside of the frame 11. At this time, the L-shaped positioning rod 92 set on the wedge block rod 71 will be separated from the annular groove 93 under the action of the inclined groove 91, and the wedge block rod 71 will move into the inside of the ratchet block 62, thereby driving the ratchet block 62 to move up and separate from the ratchet plate 61, and then the gear 2 54 can be disassembled by pulling the gear 2 54 horizontally to ensure the long-term operation of the equipment.

[0059] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.

Then, the side formwork and the cross formwork are pulled apart from the concave bottom formwork and the precast beam through the connecting assembly. S2: Wrap the binding belt around the upper body of the precast beam through the gap of the horizontal template, and hang it on the cantilever beam to lift it for demoulding; S3: While the cantilever beam is being lifted, the tooth plate moves up until the precast beam moves up to a certain height. The side formwork and the horizontal formwork are reset and spliced with the concave bottom formwork and the formwork at both ends to form a precast beam mold for casting again.
