Description

Technical Field

[0001] The invention relates to the field of construction equipment, in particular to a mould for processing prefabricated concrete components. Background Art

[0002] Prefabricated concrete components rely on centralized and large-scale production. According to different purposes and shapes, they can be used to produce prefabricated wall panels, prefabricated floor panels, prefabricated load-bearing components and stairs, etc. Concrete is poured into a mold of the corresponding shape. After a certain period of time, the concrete solidifies and the prefabricated building components are taken out. The finished components are then used to build the building, which can effectively reduce the construction period of civil engineering and effectively improve the efficiency of building construction. In the production of precast concrete components, vibrating the poured concrete is an essential process, which can effectively vibrate the bubbles and incompletely wrapped parts generated during the pouring process in the precast concrete components, and assist the concrete to better wrap around the mold and steel bars. In the process of vibrating the precast concrete components, a vibration table is mostly used. The time spent on the vibration table is too long compared to that of an electric vibrator.

[0005] Optionally, the swing fork is a telescopic structure, and when the swing fork contacts the inner side surface of the component groove, the force generated controls the swing fork to contract.

[0006] Optionally, a linkage spring rod is arranged between the two linkage rods connected by the same toothed plate, and a swing rod is arranged on both sides of each linkage rod, one end of the swing rod is hinged to the linkage rod, and the other end of the swing rod is connected to at least one vibrating rod, and the two ends of the first spring are respectively connected between the opposite surfaces between the swing rod and the linkage rod.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment: A mold for processing a precast concrete component, comprising a component slot 1, wherein the connected steel bars are placed inside the component slot 1 according to the plan, and a plurality of bottom vibrating blocks 2 are arranged inside the component slot 1, wherein each bottom vibrating block 2 is arranged in pairs; The two stacked bottom vibrating blocks 2 are symmetrically arranged with the rotating rod 3 as the center. The two displacement blocks 21 connected to the same rotating rod 3 and the control blocks 211 connected to the two displacement blocks 21 are also symmetrically arranged with the rotating rod 3 as the center. The top of each stacked bottom vibrating block 2 is connected to a sliding block 11 through the rotating rod 3. The rotating rod 3 is slidably connected to the sliding block 11. At the same time, the telescopic protective rod 4 is also slidably connected to the sliding block 11.

At the same time, the sliding block 11 is also slidably connected to the feeding block 12. The feeding block 12 slides by electrically controlling the sliding block 11. At the same time, the sliding direction of the feeding block 12 is perpendicular to the sliding direction of the rotating rod 3 and the telescopic protection rod 4. The feeding block 12 is externally connected to a feeding pipe 13, and the feeding block 12 is connected to a spraying pipe 14. The feeding pipe 13 is externally connected to a booster pump to transport concrete to the spraying pipe 14 for spraying; The bottom vibrating block 2 includes a displacement block 21, a connecting block 22, a hooking block 23, a swing fork 24, a toothed plate 25, a circulating gear 26, a circulating rack 27, a positioning rack 252 and a vibrating rod 292. The rotating rod 3 passes through the connecting block 22 and is hinged with the displacement block 21. The displacement block 21 is provided with a control block 211 away from its axis. The outer side of the control block 211 is sleeved with a swing fork 24. The swing fork 24 is provided with a conducting through groove 241. The conducting through groove 241 is embedded with the control block 211. The rotating rod 3 drives the displacement block 21 to rotate by rotating, and then the control block 211 connected to the displacement block 21 performs a circular motion around the axis of the displacement block 21, and then the swing fork 24 connected to the control block 211 will be driven to swing. When one end of the swing fork 24 is hinged by the hook block 23, the force generated by the swing fork 24 being driven by the control block 211 to swing will be transmitted to the other end of the swing fork 24, and then when the force-bearing block 261 is subjected to force on both sides of the toothed plate 25, the circulating gear 26 will start to rotate. When the position of the positioning rack 252 and the toothed plate 25 is determined, the circulation gear 26 rotates to drive the circulation rack 27 to move in the direction of the same side of the toothed plate 25, and then the circulation rack 27 will drive the linkage rod 29 on the corresponding side of the toothed plate 25 to move toward the outside.

[0021] The swing fork 24 is hinged with the hooking block 23, one end of the connecting block 22 is hinged with the hooking block 23, and the other end of the connecting block 22 is connected with the toothed plate 25, a limited slot 251 is arranged in the toothed plate 25, a force block 261 is arranged at the axis of the circulating gear 26, and the two ends of the force block 261 are respectively embedded in the limited slot 251 and the conducting slot 241, and the toothed plate 25 is provided with a circulating rack 27 and a positioning rack 252 on a side close to the side of the circulating gear 26, and the circulating rack 27 and the positioning rack 252 are symmetrically arranged with the limited slot 251 as the center, and the circulating gear 26 is respectively meshed with the circulating rack 27 and the positioning rack 252, and the circulating rack 27 is slidably connected to the toothed plate 25, and the swing fork 24 controls the force block 261 to move in the limited slot 251, and then drives the circulating rack 27 to slide relative to the two sides of the toothed plate 25 through gear transmission; The toothed plate 25 is provided with symmetrically arranged linkage rods 29 on both sides thereof, and the linkage rods 29 are movably connected with a plurality of vibrating rods 292 .

[0022] The swing fork 24 is a telescopic structure. When the swing fork 24 contacts the inner side of the component groove 1, the force generated controls the swing fork 24 to shrink; a linkage spring rod 291 is arranged between the linkage rods 29, and a receiving groove is arranged on both sides of each linkage rod 29. A swing rod 28 is arranged on both sides of each linkage rod 29. One end of the swing rod 28 is hinged in the receiving groove on the side of the linkage rod 29, and the other end of the swing rod 28 is connected to at least one vibrating rod 292. The two ends of the first spring 293 are respectively connected between the opposite surfaces between the swing rod 28 and the linkage rod 29. When the circulating rack 27 does not apply force to the linkage rod 29, the linkage spring arranged between the two linkage rods 29 on both sides of the toothed plate 25 The rod 291 will apply a pulling force to the linkage rod 29 connected at both ends of the linkage spring rod 291, and then the end of the linkage rod 29 away from the linkage spring rod 291 will contact the side of the corresponding toothed plate 25, and then the linkage rod 29 will be subjected to the pulling force and embedded in the toothed plate 25. At this time, the swing rods 28 located on both sides of the linkage rod 29 will be pushed by the toothed plate 25 because the linkage rod 29 is embedded in the toothed plate 25, and then the first spring 293 between the swing rod 28 and the linkage rod 29 will be squeezed, until the swing rod 28 is pushed into the receiving groove by the toothed plate 25, and then the vibrating rod 292 connected to the swing rod 28 will also be located near the side of the linkage rod 29; However, when the circulating gear 26 rotates and drives the circulating rack 27 to move toward one side of the toothed plate 25, the circulating rack 27 pushes the linkage rod 29 to move accordingly, and the linkage rod 29 moves in the direction away from the toothed plate 25, and the swing rod 28 is no longer in contact with the toothed plate 25, and the first spring 293 is extended accordingly, thereby pushing the swing rod 28 to swing in the direction away from the linkage rod 29, and the vibrating rod 292 moves in the direction away from the linkage rod 29.

[0023] In the two stacked bottom vibrating blocks 2, a telescopic protective rod 4 is respectively provided on both sides of the toothed plate 25 of the upper bottom vibrating block 2, and the telescopic protective rod 4 is respectively provided with a plurality of arc-shaped flexible sheets 41 on the side away from the rotating rod 3, and a second spring 42 is provided between each flexible sheet 41 and the telescopic protective rod 4 for connection; the telescopic protective rod 4 is connected to one end of a telescopic adjustment rod 5 on the side away from the rotating rod 3, and the other end of the telescopic adjustment rod 5 is connected to an adjustment ring 51, and the adjustment ring 51 is sleeved with a spray pipe 14; By extending and retracting the telescopic adjustment rod 5, the spraying pipe 14 can adjust the distance between itself and the telescopic protective rod 4. At the same time, through the sliding of the telescopic protective rod 4 at the sliding block 11, the spraying pipe 14 can realize the movement perpendicular to the extension and retraction direction of the telescopic adjustment rod 5. At the same time, in conjunction with the sliding between the sliding block 11 and the feed block 12, the spraying pipe 14 can realize the spraying of materials in all areas of the component groove 1. At the same time, the telescopic protective rod 4 can be extended and retracted, thereby controlling the two stacked bottom vibrating blocks 2 to move upward, thereby avoiding affecting the spraying of materials by the spraying pipe 14.

[0024] The working process of this embodiment is as follows: connected steel bars are placed in the component groove 1, and when the bottom vibrating block 2 is not working, the external booster pump controls the concrete to be transported toward the feeding block 12 through the feeding pipe 13, and then sprayed out through the spraying pipe 14. Under electric control, the sliding block 11 slides relative to the feeding block 12, and the telescopic protection rod 4 slides relative to the sliding block 11 and the telescopic adjustment rod 5 is adjusted, and the adjustment ring 51 guides the spraying pipe 14 to face various areas in the component groove 1, and concrete is poured inside the component groove 1. When the steel bars and the bottom part of the component groove 1 are poured, Under, the telescopic protection rod 4 moves the two stacked bottom vibrating blocks 2 to the appropriate position through telescopic control, and then the rotating rod 3 is rotated under electric control, and at the same time, the symmetrically arranged control blocks 211 will still be symmetrically arranged with the rotating rod 3 as the center, and then the circulating racks 27 connected to the two bottom vibrating blocks 2 will have two relative situations, one is that the two circulating racks 27 are both embedded in the toothed plate 25, and the other is that the two circulating racks 27 will be displaced in opposite directions; and then under the continuous rotation of the rotating rod 3, the vibrating rods 292 connected to the two stacked bottom vibrating blocks 2 will cyclically displace on both sides of the toothed plate.

[0025] By changing the position of the control block 211, the swing fork 24 is driven to swing. Under the hinged action of the swing difference and the hooking block 23, the end of the swing fork 24 that is not connected to the hooking block 23 will have a relatively large swing amplitude, and then the conductive through groove 241 of the swing fork 24 applies a force consistent with the direction of the limit through groove 251 to the force block 261, thereby controlling the circulation gear 26 to rotate. When the positions of the positioning rack 252 and the toothed plate 25 are determined, the circulation rack 27 moves in the same direction as the circulation gear 26 until the circulation rack 27 pushes the linkage rod 29 to run in the same direction, and then the receiving groove of the linkage rod 29 stops contacting with the toothed plate 25, and then the first spring 293 that loses the compression of the toothed plate 25 stretches, thereby pushing the swing of the swing rod 28, and then the end of the swing rod 28 connected to the vibrating rod 292 will swing, thereby vibrating a larger area; This causes the vibrating rod 292 connected to the linkage rod 29 to extend in different directions, and controls the rotation speed of the rotating rod 3 to match the sliding speed of the rotating rod 3 at the sliding block 11, so that the area at the bottom of the steel bar and the component groove 1 can be fully vibrated, while avoiding the separation of concrete aggregates due to excessive vibration time; When the position adjustment of the telescopic adjustment sense and the position adjustment between the sliding block 11 and the feed block 12 are incorrect, the telescopic protection rod 4 may be closer to the steel bar, and then the flexible sheet 41 will contact the steel bar, and the second spring 42 will deform accordingly, bearing most of the stress to avoid damage to the steel bar and the device itself.
