Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component manufacturing, in particular to a manufacturing device for concrete prefabricated components. Background Art

[0002] Precast concrete refers to a construction method in which concrete components are manufactured in advance in a factory or production site and then transported to the site for installation and assembly. This method has many advantages over traditional on-site cast concrete, including improved quality control, production efficiency and construction speed. Precast concrete can be applied to various construction projects, including residential buildings, commercial buildings, bridges, tunnels, etc. It can improve construction efficiency and reduce on-site construction time while ensuring the quality and consistency of concrete components.

[0003] Currently, when using precast concrete parts manufacturing devices on the market, multiple reinforcing bars need to be inserted into the interior of the concrete, and most precast concrete parts manufacturing devices are not equipped with guiding and positioning devices. As a result, the reinforcing bars may be positioned or skewed when placed. In addition, when removing the existing precast concrete parts, they may stick to the inside of the mold, making it impossible for the existing precast concrete parts manufacturing devices to accurately guide the installation of steel bars and guide the pushing of precast concrete parts.

[0032] like Figure 2The alignment component 1 includes a rack 5, a connecting vertical frame 6, a horizontal frame 7, a first hydraulic cylinder 8, a supporting base frame 9 and a receiving device 10.

By starting the first hydraulic cylinder 8, the horizontal frame 7 can be driven to rise as a whole, which facilitates the misalignment of the receiving device 10 and the top of the steel bar.

[0033] like Figure 3 The receiving device 10 includes a displacement frame 11, a top plate 12, an alignment guide rod 13, an L-shaped receiving seat 14 and a first spring 15. The top plate 12 is fixedly mounted on the inner top of the displacement frame 11, the first spring 15 is fixedly mounted on the inner end of the displacement frame 11 away from the top plate 12, the L-shaped receiving seat 14 is fixedly mounted on the end of the first spring 15 close to the top plate 12, the alignment guide rod 13 passes through the displacement frame 11 and is fixed on both sides of the L-shaped receiving seat 14, and the pointer on the top of the displacement frame 11 close to the top plate 12 moves on the scale line on the top of the cross frame 7, so that the user can accurately control the displacement of the displacement frame 11.

[0034] The rack 5 is engaged with the gear 28, the support base 9 is slidably sleeved on the guide column 18, the displacement frame 11 is slidably inserted into the inside of the cross frame 7, and the inner center thread of the displacement push plate 26 is sleeved on the threaded rod 16. When the threaded rod 16 rotates, it can drive the displacement push plate 26 to move.

[0035] Transverse grooves are provided on both sides of the interior of the cross frame 7 , and displacement keys are fixedly installed on both ends of the displacement frame 11 . The alignment guide rod 13 passes through the side end of the cross frame 7 close to the rack 5 , allowing the displacement frame 11 to slide inside the cross frame 7 .

[0036] A docking hole is provided at the center of the top of the top plate 12, and movable grooves adapted to the alignment guide rod 13 are provided on both sides of the displacement frame 11. The alignment guide rod 13 is horizontally aligned with the alignment plate 17 to improve the docking accuracy of the alignment guide rod 13 and the alignment plate 17.

[0037] The bottom sides of the L-shaped side block 25 and the top sides of the protrusion 24 are all inclined at 45°. A reset button is fixedly installed at the top rear end of the prefabricated mold 23, and the reset button and the photoelectric sensor 4 are electrically connected to the second hydraulic cylinder 31. A trigger rod is fixedly installed at the bottom center of the protrusion 24, and the trigger rod passes through the interior of the back plate 29. The front top of the L-shaped front cover 30 is vertically aligned with the second hydraulic cylinder 31. An extended side strip is fixedly installed through the front end of the L-shaped front cover 30, and when the L-shaped front cover 30 moves downward to the extreme position, it can drive the extended side strip to fit with the top of the second hydraulic cylinder 31, so that when the second hydraulic cylinder 31 is started, it can drive the L-shaped front cover 30 to rise.

[0038] A card key is symmetrically fixed on the rear end of the L-shaped front sealing plate 30, and a vertical groove adapted to the card key is opened on the front end of the prefabricated mold 23. The limiting bottom plate 37 is arranged in a U-shaped state, and the front end top of the limiting bottom plate 37 is slidably inserted into the bottom end of the baffle 36, which can ensure that the limiting bottom plate 37 slides up and down in a straight line.

[0039] The working principle of embodiment 1 is as follows: when in use, first pass the external steel bars through the top plate 12 and place them on the top of the L-shaped receiving seat 14 so that the steel bars can be received. After that, the external concrete can be poured into the interior of the precast mold 23 until the concrete fills the precast mold 23. Then the second motor 20 is started to drive the gear 28 to rotate, and the gear 28 is engaged with the rack 5, so that when the gear 28 rotates, it can simultaneously drive the two racks 5 to move toward each other, so that the cross frame 7 can approach each other, and the support base 9 is slidably sleeved on the guide column 18, so that the cross frame 7 can be supported to move in a straight line, thereby improving the docking accuracy of the cross frame 7 and the cross frame 7. When the cross frame 7 moves toward each other to the extreme position, it can drive the alignment guide rod 13 and the alignment plate 17 to be squeezed. The blocking of the plate 17 can squeeze the alignment guide rod 13 to move toward the inside of the displacement frame 11. When the L-shaped receiving seat 14 is dislocated from the bottom end of the steel bar inside the top plate 12, the steel bar inside the top plate 12 will fall downward into the concrete inside the precast mold 23, and when the steel bar falls downward to the limit position, the top part will remain inside the top plate 12, so as to prevent the steel bar from being skewed. After the concrete is dried and formed, the first hydraulic cylinder 8 can be started to drive the cross frame 7 to move upward. When the cross frame 7 moves upward to the limit position, it can drive the top plate 12 and the top end of the steel bar to be dislocated, so as to prevent the top plate 12 and the steel bar from interfering. At the same time, the alignment guide rod 13 will also move to be dislocated with the alignment plate 17. After that, the first spring 15 The elasticity will drive the alignment guide rod 13 to quickly reset, so that the L-shaped receiving seat 14 is vertically aligned with the top plate 12 again, which is convenient for receiving the steel bars. When the prefabricated concrete part needs to be moved out of the interior of the prefabricated mold 23, the first motor 19 can be started to drive the threaded rod 16 to rotate, and the displacement push plate 26 is threadedly sleeved on the threaded rod 16, so that the displacement push plate 26 moves along the interior of the prefabricated mold 23. When the displacement push plate 26 moves, it extends backward through the top rear end of the displacement push plate 26, and a partition plate is inserted at the rear end of the side end of the prefabricated mold 23, so that the partition plate can be pulled out from the interior of the prefabricated mold 23 in advance, and there is a 5 cm gap between the partition plate and the displacement push plate 26. When the displacement push plate 26 drives the L-shaped side block 25 to move to the front end, it can be pulled out from the protrusion The top of the L-shaped side block 24 passes through the top ends of the protrusion 24 and the bottom ends of the L-shaped side block 25, which are all inclined at 45 degrees, so that the smoothness of the L-shaped side block 25 when passing the protrusion 24 can be improved. When the lowest point of the bottom end of the L-shaped side block 25 contacts the top of the protrusion 24, the trigger rod at the bottom end of the protrusion 24 can be driven to penetrate the back plate 29 to squeeze the L-shaped connecting rear frame 22 to move downward. The synchronous bottom rod 32 is fixedly installed between the L-shaped connecting rear frames 22, and the limiting bottom plate 37 is fixedly installed at the front end of the synchronous bottom rod 32. When the L-shaped connecting rear frame 22 moves downward, the limiting bottom plate 37 can be driven to pull the connecting rope 33 downward. Through the setting of the guide auxiliary wheel 38, the bottom end of the baffle 36 can be used as a reference to pull the L-shaped blocking bottom plate 34 to move toward the rear end.When the L-shaped connecting rear frame 22 moves downward to the limit position, it can drive the L-shaped blocking bottom plate 34 to be misaligned with the bottom end of the L-shaped front sealing plate 30. Later, when the L-shaped front sealing plate 30 loses its support, the front end top of the L-shaped front sealing plate 30 can slide downward until it contacts the top end of the second hydraulic cylinder 31, and the key at the rear end of the L-shaped front sealing plate 30 slides in the vertical groove inside the front end of the precast mold 23, so as to prevent the L-shaped front sealing plate 30 from falling off. When the L-shaped side block 25 passes the protrusion 24, the displacement push plate 26 contacts the rear end of the concrete precast part, so that the displacement push plate When the motor 26 moves, the concrete precast part inside the precast mold 23 can be pushed to move toward the front end, so that the front end of the concrete precast part will move to the top of the guide platform 3. When the front end of the concrete precast part passes the top of the photoelectric sensor 4, the rear end of the concrete precast part can move out from the top of the L-shaped front sealing plate 30, which can trigger the photoelectric sensor 4, so that the second hydraulic cylinder 31 can be started, driving the L-shaped front sealing plate 30 to move upward, so that the L-shaped front sealing plate 30 can close the front end of the precast mold 23 again, so that the concrete can be taken in again. After that, the first motor 19 can be driven again. When the displacement push plate 26 is started again, the threaded rod 16 is driven to rotate in the opposite direction, causing the displacement push plate 26 to reset to the rear end. When the displacement push plate 26 moves to the extreme position toward the rear end, it can drive the L-shaped side block 25 to contact the reset button on the top of the rear end of the precast mold 23, so that the second hydraulic cylinder 31 can be reset. The L-shaped front sealing plate 30 is located above the L-shaped blocking bottom plate 34. Subsequently, the partition plate can be inserted into the side end of the precast mold 23 again, so that the interior of the precast mold 23 can be closed, which is convenient for receiving concrete again. When the displacement frame 11 is in use, the pseudo-opinions at both ends of the displacement frame 11 are used to press the horizontal frame. 7 slides in the internal transverse groove, so that the spacing of the steel bars can be adjusted. At the same time, when the position of the displacement frame 11 is determined, the threaded rod at the end of the displacement frame 11 away from the positioning guide rod 13 can be screwed until it is fastened to the cross frame 7, so that the displacement frame 11 can be positioned. When the displacement frame 11 moves, a pointer is fixedly installed on the top of the top plate 12 away from the first spring 15, and a scale line is marked on the top end of the cross frame 7 near the rack 5. When the displacement frame 11 moves, it can drive the pointer to move on the scale line, thereby facilitating the user to accurately control the spacing of the steel bars. Example 2

[0040] On the basis of Example 1, Figure 8As shown, the displacement frame 11 also includes a central cavity 39, a transfer funnel 40, an alignment vertical pipe 41, a bottom end blocking plate 42, a contact vertical plate 43, a fourth spring 44 and a support extension frame 45. The central cavity 39 is fixedly mounted on the top of the support extension frame 45, the alignment vertical pipe 41 is fixedly mounted on the front end of the support extension frame 45, the alignment vertical pipe 41 is located below the central cavity 39, the transfer funnel 40 is fixedly mounted on the top of the alignment vertical pipe 41, the bottom end blocking plate 42 is slidably inserted into the bottom end of the alignment vertical pipe 41, the fourth spring 44 is fixedly mounted between the bottom end blocking plate 42 and the support extension frame 45, the contact vertical plate 43 is fixedly mounted at the bottom front end of the bottom end blocking plate 42, the central cavity 39 is inclined at 30°, and a circular hole is opened in the central cavity 39 near the bottom of the transfer funnel 40. The interiors of the transfer funnel 40 and the alignment vertical pipe 41 are interconnected, and the alignment vertical pipe 41 is vertically aligned with the top of the top plate 12.

[0041] When implementing this embodiment, the external steel bars can be placed in the interior of the centralized cavity 39 in sequence. The centralized cavity 39 is tilted at 30 degrees, and the lowest point of the centralized cavity 39 is aligned with the transfer funnel 40, so that the steel bars inside the centralized cavity 39 will always slide downward and fall into the interior of the transfer funnel 40. A circular hole is opened at the bottom of one end of the centralized cavity 39 close to the transfer funnel 40, and the circular hole is the same thickness as the steel bar, so that the centralized cavity 39 can only transmit one steel bar at a time. Afterwards, the steel bar can enter the interior of the transfer funnel 41 through the transfer funnel 40. The bottom of the vertical pipe 41 is placed at the bottom, and at the same time, when the bottom blocking plate 42 remains normal, the elasticity of the fourth spring 44 will drive the bottom blocking plate 42 to close the bottom end of the positioning vertical pipe 41, so as to prevent the steel bar from falling in advance. The docking piece is fixedly installed on the top of the top plate 12 close to the top of the first spring 15, and the docking piece is horizontally aligned with the bottom end of the contact vertical plate 43, so that when the cross frame 7 moves outward to the extreme position, the bottom blocking plate 42 and the bottom end of the positioning vertical pipe 41 can be squeezed out of position, so that the steel bar inside the positioning vertical pipe 41 will pass through the top plate 12 and fall onto the top of the L-shaped receiving seat 14, completing the work of automatically replenishing the steel bar.
