A mold for processing precast concrete components

Abstract

The present invention is a mold for processing precast concrete components, including a component groove, a bottom vibrating block, a rotating rod, etc. By rotating the rotating rod, the displacement blocks in the two stacked bottom vibrating blocks are driven to rotate accordingly, and then the two swing forks are driven to swing together. Due to the different positions of the positioning blocks in the two displacement blocks, the swinging directions of the two swing forks are also different. As a result, the relative positions and moving directions of the different circulating gears and circulating racks connected by the two swing forks are also different. Thus, the interval area between the bottom of the component groove and the steel bars is vibrated internally by the vibrating rods connected to the bottom vibrating blocks. At the same time, multiple bottom vibrating blocks are arranged in the component groove, which can quickly and effectively vibrate the bottom of the component groove that is difficult to penetrate originally.

Description

Technical Field

[0001] The present invention relates to the field of construction equipment, and particularly to a mold for processing concrete precast components. Background Art

[0002] Concrete precast components rely on centralized and large - batch production. According to different purposes and shapes, precast wall panels, precast floor slabs, precast load - bearing components, stairs, etc. can be produced. By pouring concrete into molds of corresponding shapes, through the reasonable arrangement of concrete and steel bars in the molds, after waiting for a certain period of time, when the concrete solidifies, the precast building components are taken out, and then the completed components are used for building construction. This can effectively reduce the construction period of civil engineering construction and effectively improve the construction efficiency of buildings.

[0003] In the production of concrete precast components, during the production process of concrete precast components, vibrating the poured concrete is an essential process. It can effectively vibrate the bubbles generated during the pouring process and the parts that are not fully wrapped in the concrete precast components, and assist the concrete to better wrap around the mold and steel bars. During the vibration process of concrete precast components, a vibrating table is mostly used for vibration. The time spent on the vibrating table is relatively long compared to an electric vibrating rod. At the same time, the cost of building a vibrating table in some uneven or soft - geological areas is too high. Therefore, in some cases, an electric vibrating rod is also used. However, for the gap between the bottom of the mold and the steel bars, it takes a lot of effort to align the position when inserting the electric vibrating rod, and the labor cost and time cost required are relatively large. Summary of the Invention

[0004] The purpose of the present invention is to provide a mold for processing concrete precast components, so as to solve the problem that it is difficult to vibrate some areas of concrete precast components in the existing scenario when using an electric vibrating rod.

[0005] To solve the above problems, the present invention provides the following technical solution: A mold for processing concrete precast components, including a component groove. Inside the component groove, a number of bottom vibrating blocks are provided. Each of the bottom vibrating blocks is arranged in a stacked manner in pairs. The tops of each pair of stacked bottom vibrating blocks are respectively connected to sliding blocks through rotating rods. The rotating rods are slidably connected to the sliding blocks. The top of the sliding block is provided with a feeding block. The feeding block is externally connected to a feeding pipe, and the feeding block is connected to a spraying pipe.

[0006] The bottom vibrating block includes a displacement block, a connecting block, a hook - connecting block, a swinging fork, a toothed plate, a circulating gear, a circulating rack, a positioning rack, and a vibrating rod. The rotating rod passes through the connecting block and is hinged to the displacement block. The displacement block is provided with a control block at a position far from its axis. The outside of the control block is sleeved with a swinging fork. A conduction through - groove is arranged inside the swinging fork, and the control block is embedded in the conduction through - groove.

[0007] The swing fork is hinged to the connecting block. One end of the connecting block is hinged with a connecting block, and the other end of the connecting block is connected with a toothed plate. A limiting through groove is arranged in the toothed plate. A stress block is arranged at the axis of the circulating gear. Both ends of the stress block are respectively embedded in the limiting through groove and the conduction through groove. The toothed plate is provided with a circulating rack and a positioning rack on the side close to the side of the circulating gear. The circulating rack and the positioning rack are symmetrically arranged with the limiting through groove as the center. The circulating gear meshes with the circulating rack and the positioning rack respectively. The circulating rack is slidably connected to the toothed plate. The swing fork drives the circulating rack to slide relative to both sides of the toothed plate through gear transmission by controlling the movement of the stress block in the limiting through groove;

[0008] Both sides of the toothed plate are respectively provided with symmetrically arranged linkage rods, and a plurality of vibrating rods are movably connected to the linkage rods.

[0009] Optionally, the swing fork is a telescopic structure. When the swing fork contacts the inner side surface of the component groove, the generated acting force controls the swing fork to contract.

[0010] Optionally, a linkage spring rod is arranged between the two linkage rods connected to the same toothed plate. Swing rods are respectively 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 with at least one vibrating rod. Both ends of a first spring are respectively connected between the opposite surfaces of the swing rod and the linkage rod.

[0011] Optionally, telescopic protective rods are respectively arranged on both sides of the toothed plate. A plurality of flexible sheets are arranged on the side of the telescopic protective rod away from the rotating rod. A second spring is arranged between each flexible sheet and the telescopic protective rod for connection.

[0012] Optionally, the outer shape of the flexible sheet is arc-shaped.

[0013] Optionally, one end of a telescopic adjusting rod is connected to the side of the telescopic protective rod away from the rotating rod, and the other end of the telescopic adjusting rod is connected to an adjusting ring.

[0014] Optionally, a spray pipe is sleeved on the adjusting ring, and the telescopic adjusting rod controls the distance between the adjusting ring and the telescopic protective rod through telescopic adjustment.

[0015] Beneficial effects: 1. The rotating rod of the present invention can drive the displacement block to rotate, and then the position control block connected to the displacement block makes a circular motion around the axis of the displacement block. As a result, the swing fork connected to the position control block will be driven to swing. When one end of the swing fork is hinged by the hook block, the force generated by the swing of the swing fork will be transmitted to the other end of the swing fork. Then, when the force receiving block is subjected to forces applied to both sides towards the toothed plate, the circulating gear will start to rotate. When the positions of the positioning rack and the toothed plate are determined, the rotating circulating gear drives the circulating rack to move towards the same side of the toothed plate. Then, the linkage rod on the corresponding side of the toothed plate driven by the circulating rack will move towards the outside. As a result, the first spring on the side of the linkage rod will extend after losing the restraint of the toothed plate, and then drive the swing rod to swing. At this time, the vibrating rod controlled by electricity will vibrate the concrete in a wider range at the bottom of the component groove, and thus can vibrate the area that was difficult for the previous vibrating rod to reach more quickly.

[0016] 2. A second spring is provided between the telescopic protective rod and the flexible sheet. When the positions of the rotating rod and the telescopic protective rod are controlled by the sliding block and the material conveying pipe to move, if the telescopic protective rod touches the steel bars in the component groove due to a mistake during the movement, the flexible sheet will relieve this collision, thereby effectively protecting against potential safety hazards that may occur when the positions of the rotating rod and the telescopic protective rod are changed by electric control.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. 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 those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] Embodiment: A mold for processing concrete precast components includes a component groove 1. Reinforcing bars connected together are placed inside the component groove 1 according to the plan. A number of bottom vibrating blocks 2 are arranged inside the component groove 1, and each pair of bottom vibrating blocks 2 is stacked on top of each other.

[0025] The two stacked bottom vibrating blocks 2 are symmetrically arranged around the rotating rod 3. Between the two displacement blocks 21 connected by the same rotating rod 3, the position control blocks 211 connected by these two displacement blocks 21 are also symmetrically arranged around the rotating rod 3. At the top of each pair of stacked bottom vibrating blocks 2, sliding blocks 11 are respectively connected through rotating rods 3. The rotating rods 3 are slidably connected to the sliding blocks 11. At the same time, the telescopic protective rods 4 are also slidably connected to the sliding blocks 11. The sliding blocks 11 are electrically controlled to slide the rotating rods 3 and the telescopic protective rods 4 at the sliding blocks 11. At the top of the sliding blocks 11, feeding blocks 12 are arranged. At the same time, the sliding blocks 11 are also slidably connected to the feeding blocks 12. The feeding blocks 12 are electrically controlled to slide the sliding blocks 11. At the same time, the sliding direction of the feeding blocks 12 is perpendicular to the sliding directions of the rotating rods 3 and the telescopic protective rods 4. The feeding blocks 12 are externally connected with feed pipes 13, and the feeding blocks 12 are connected with spray pipes 14. The feed pipes 13 convey concrete to the spray pipes 14 for spraying through an externally connected booster pump.

[0026] The bottom vibration block 2 includes a displacement block 21, a connection block 22, a hook connection block 23, a swing fork 24, a toothed plate 25, a circulating gear 26, a circulating rack 27, a positioning rack 252 and a vibration rod 292. A rotating rod 3 passes through the connection block 22 and is hinged with the displacement block 21. A position control block 211 is arranged at a position far from the axis of the displacement block 21. A swing fork 24 is sleeved outside the position control block 211. A conduction through groove 241 is arranged inside the swing fork 24, and the position control block 211 is embedded in the conduction through groove 241.

[0027] The rotating rod 3 drives the displacement block 21 to rotate accordingly through rotation. Furthermore, the position control block 211 connected to the displacement block 21 performs circular motion around the axis of the displacement block 21. Furthermore, the swing fork 24 connected to the position control block 211 will be driven to swing. When one end of the swing fork 24 is hinged with the hook connection block 23, the force generated by the swing of the swing fork 24 driven by the position control block 211 will be conducted to the other end of the swing fork 24. Furthermore, when the force receiving block 261 is subjected to forces applied to both sides towards the toothed plate 25, the circulating gear 26 will start to rotate. When the positions of the positioning rack 252 and the toothed plate 25 are determined, the circulating gear 26 rotates to drive the circulating rack 27 to move towards the same side of the toothed plate 25. Furthermore, the circulating rack 27 will drive the linkage rod 29 on the corresponding side of the toothed plate 25 to move towards the outside.

[0028] The swing fork 24 is hinged with the hook connection block 23. One end of the connection block 22 is hinged with the hook connection block 23. The other end of the connection block 22 is connected with the toothed plate 25. A limit through groove 251 is arranged inside the toothed plate 25. A force receiving block 261 is arranged at the axis of the circulating gear 26. Both ends of the force receiving block 261 are respectively embedded in the limit through groove 251 and the conduction through groove 241. The toothed plate 25 is provided with a circulating rack 27 and a positioning rack 252 on the side close to the circulating gear 26. The circulating rack 27 and the positioning rack 252 are symmetrically arranged with the limit through groove 251 as the center. The circulating gear 26 meshes with the circulating rack 27 and the positioning rack 252 respectively. The circulating rack 27 is slidably connected to the toothed plate 25. The swing fork 24 drives the force receiving block 261 to move in the limit through groove 251, and then drives the circulating rack 27 to slide relative to both sides of the toothed plate 25 through gear transmission.

[0029] Symmetrically arranged linkage rods 29 are respectively arranged on both sides of the toothed plate 25. A plurality of vibration rods 292 are movably connected to the linkage rods 29.

[0030] The swing fork 24 is a telescopic structure. When the swing fork 24 contacts the inner side surface of the component groove 1, the generated acting force controls the swing fork 24 to contract. A linkage spring rod 291 is arranged between the linkage rods 29. Receiving grooves are arranged on both sides of each linkage rod 29. Swing rods 28 are respectively 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 surface of the linkage rod 29, and at least one vibrating rod 292 is connected to the other end of the swing rod 28. Both ends of a first spring 293 are respectively connected between the opposite surfaces of 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 rod 291 arranged between the two linkage rods 29 located on both sides of the toothed plate 25 will apply a pulling force to the linkage rods 29 connected to both ends of the linkage spring rod 291. Then, the end of the linkage rod 29 away from the linkage spring rod 291 will contact the side surface of the corresponding toothed plate 25. Then, the linkage rod 29 will be subjected to a pulling force and be embedded in the toothed plate 25. At this time, the swing rods 28 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. Then, the first spring 293 between the swing rod 28 and the linkage rod 29 will be compressed until the swing rod 28 is pushed into the receiving groove by the toothed plate 25. Then, the vibrating rod 292 connected to the swing rod 28 will also be located at the side close to the linkage rod 29.

[0031] However, when the circulating gear 26 rotates to drive the circulating rack 27 to move together towards one side of the toothed plate 25, the circulating rack 27 immediately pushes the linkage rod 29 to move accordingly. Then, the linkage rod 29 moves in a direction away from the toothed plate 25. Subsequently, the swing rod 28 no longer contacts the toothed plate 25. Then, the first spring 293 extends accordingly, and then pushes the swing rod 28 to swing in a direction away from the linkage rod 29. The vibrating rod 292 moves in a direction away from the linkage rod 29 accordingly.

[0032] In the two stacked bottom vibrating blocks 2, a telescopic protective rod 4 is respectively arranged on both sides of the toothed plate 25 of the upper bottom vibrating block 2. A plurality of arc-shaped flexible sheets 41 are respectively arranged on the side of the telescopic protective rod 4 away from the rotating rod 3. A second spring 42 is arranged between each flexible sheet 41 and the telescopic protective rod 4 for connection. One end of a telescopic adjusting rod 5 is connected to the side of the telescopic protective rod 4 away from the rotating rod 3. The other end of the telescopic adjusting rod 5 is connected to an adjusting ring 51. The adjusting ring 51 is sleeved with a material spraying pipe 14.

[0033] By the telescopic movement of the telescopic adjusting rod 5, the spraying pipe 14 can adjust its distance from the telescopic protective rod 4. At the same time, by the sliding of the telescopic protective rod 4 at the sliding block 11, the spraying pipe 14 can move perpendicular to the telescopic direction of the telescopic adjusting rod 5. Then, in cooperation with the sliding between the sliding block 11 and the material conveying block 12, the spraying pipe 14 can spray materials on all areas of the component groove 1. At the same time, the telescopic protective rod 4 can be telescoped, thereby controlling the two stacked bottom vibrating blocks 2 to move upward, so as to avoid affecting the spraying of the spraying pipe 14.

[0034] The working process of this embodiment is as follows: Reinforcing bars after connection are placed in the component groove 1. When the bottom vibrating blocks 2 have not started working, an external booster pump controls the concrete to be transported into the material conveying block 12 through the feed pipe 13 and then sprayed out through the spraying pipe 14. Under electric control, the sliding block 11 slides relative to the material conveying block 12. Under the sliding of the telescopic protective rod 4 relative to the sliding block 11 and the telescopic adjustment of the telescopic adjusting rod 5, the adjusting ring 51 guides the spraying pipe 14 to face each area in the component groove 1 for concrete pouring inside the component groove 1. When the pouring of the reinforcing bars and the bottom part of the component groove 1 is completed, the telescopic protective rod 4 controls the two stacked bottom vibrating blocks 2 to move to appropriate positions through telescoping. Then, the rotating rod 3 is rotated under electric control, and at the same time, the symmetrically arranged position control blocks 211 will still be symmetrically arranged with the rotating rod 3 as the center. As a result, there will be two relative situations for the circulating racks 27 connected to the two bottom vibrating blocks 2. One is that both circulating racks 27 are embedded in the toothed plate 25, and the other is that the two circulating racks 27 will displace in opposite directions. 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.

[0035] Due to the change in the position of the position control block 211, the swing fork 24 is driven to swing. Under the hinge action between the swing fork and the hook block 23, the end of the swing fork 24 not connected to the hook block 23 will have a relatively large swing amplitude. As a result, the conduction through groove 241 of the swing fork 24 applies a force in the same direction as the limit through groove 251 to the force receiving block 261, thereby controlling the rotation of the circulating gear 26. When the positions of the positioning rack 252 and the toothed plate 25 are determined, the circulating rack 27 will move in the same direction as the circulating gear 26 until the circulating rack 27 pushes the linkage rod 29 to run in the same direction. As a result, the receiving groove of the linkage rod 29 will stop contacting the toothed plate 25, and the first spring 293 that loses the extrusion of the toothed plate 25 will then stretch, thereby pushing the swing of the swing rod 28. As a result, the end of the swing rod 28 connected to the vibrating rod 292 will swing, thereby vibrating a larger area.

[0036] Furthermore, it prompts the vibrating rod 292 connected to the linkage rod 29 to extend in different directions, controls the rotation speed of the rotating rod 3 to match the sliding speed of the rotating rod 3 at the sliding block 11, and thus can fully vibrate the area of the steel bars and the bottom of the component groove 1, while avoiding the separation of concrete aggregates caused by excessive vibration time;

[0037] When there are mistakes in the position adjustment of the telescopic adjustment sensor and the position adjustment between the sliding block 11 and the material conveying block 12, it is possible that the position of the telescopic protective rod 4 is relatively close to the steel bars. As a result, the flexible sheet 41 will contact the steel bars, and the second spring 42 will deform accordingly, bearing most of the stress and preventing damage to the steel bars and the device itself.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
