Description

Technical Field

[0001] The present invention relates to the technical field of concrete forming, and particularly to a concrete forming device for construction engineering. Background Art

[0002] Concrete is a composite material composed of cement as a gelling material, sand and gravel as aggregates, and water (which may contain admixtures and additives) mixed in a certain proportion. In construction, for areas with a long construction period, concrete precast elements are often used to reduce the impact of uncertain factors such as weather on the construction progress. When the existing concrete forming device produces precast elements, the general process is as follows: First, pour the pre-mixed concrete slurry into a specified mold, then place a steel bar frame in the mold filled with concrete to enhance the strength of the precast element, then wait for the concrete to solidify, and finally demold and take out.

[0003] However, during the process of placing the steel bar frame, the existing process usually directly places the steel bar frame on the surface of the concrete in the mold and then makes it gradually sink into the concrete by continuous vibration. However, during this process, due to the lack of effective support for the steel bar frame, the settlement speeds of different parts of the steel bar frame are inconsistent, which easily leads to uneven distribution in the concrete or even excessive settlement. This will not only cause differences in strength at various places after the concrete solidifies, but also significantly affect the overall quality of the concrete precast element. Summary of the Invention

[0004] The present invention provides a concrete forming device for construction engineering to overcome the problem that the steel bar frame lacks support during the settlement of concrete and is prone to uneven or excessive settlement.

[0034] 3.

Detailed implementation manners

[0045] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and explanations of the present invention are used to explain the present invention, but do not limit the present invention.

[0046] A concrete forming device for construction engineering, as Figures 1-7As shown, it includes: a conveying frame 1, which is provided with a conveyor belt for driving the mold to move; a material discharge module 2, which is arranged on the conveying frame 1 and is used to fill concrete materials into the mold; a moving frame 3, which is arranged on the material discharge module 2, and the moving frame 3 is provided with an electric telescopic rod 4; a lifting rod 5, which is fixed to the telescopic end of the electric telescopic rod 4, and the lifting rod 5 is provided with a buffer shell 6; a lifting frame 7, which is fixed to the buffer shell 6, and the lifting frame 7 is provided with an adjustment frame 8, and the adjustment frame 8 is fixed with circumferentially distributed support rods 9; arc frames 10, the number of which is the same as the number of support rods 9, which are respectively hinged on adjacent support rods 9, and the arc frames 10 are used to fix the position of the steel frame, and a first torsion spring 11 is fixed between the support rod 9 and the adjacent arc frames 10, and a vibration module 12 is fixed on the arc frame 10, and the vibration module 12 is used to vibrate the support rod 9; a fixing component, the number of which is the same as the number of support rods 9, is used to limit the steel frame.

[0047] The above scheme provides a method for moving the steel frame to a specified position in the mold (i.e., a position close to the middle of the concrete, which can be located above the middle) by fixing the edge of the steel frame and driving it to move during the process of placing the steel frame; a spraying module is provided on the conveying frame 1, and the spraying module is used to evenly spray the release agent into the mold. The spraying module is an existing device, and its specific structure will not be described in detail. The conveyor belt on the conveying frame 1 is an existing device, which is used to drive the mold to move from left to right. A vibration motor is provided in the conveying frame 1, which is used to drive the conveyor belt of the conveying frame 1 to vibrate. A material storage rack not shown is provided on the front side of the conveying frame 1, and the material storage rack is used to place the steel frame; the unloading module 2 is an existing device, and its specific structure and use method will not be described in detail; the moving frame 3 is composed of an electric slide rail and an electric slider, and the electric telescopic rod 4 is fixed to the electric slider In this embodiment, the moving frame 3 has two electric telescopic rods 4 (in the following description, one electric telescopic rod 4 is used to represent it), which are used to stabilize the force on the lifting rod 5, and the moving frame 3 drives the electric telescopic rod 4 to move through the electric slider thereon; in this embodiment, the relationship between the lifting rod 5 and the buffer shell 6 is fixed, and the lifting rod 5 directly drives the buffer shell 6 to move, and the relationship between the lifting frame 7 and the adjustment frame 8 is fixed; in this embodiment, the number of support rods 9 and parts thereon is four, which are used to fix the four edges on the upper side of the steel frame; the cross-section of the arc frame 10 is U-shaped, and the arc frame 10 is used to clamp the edge of the steel frame. The width of the arc frame 10 can be adjusted according to actual usage. The first torsion spring 11 is used to drive the arc frame 10 to reset. In this example, a steel frame is placed between the four arc frames 10 at the beginning.

[0048] Further, such as Figures 4-7As shown in the figure, the fixing component includes: a fixing frame 13, hinged to the arc-shaped frame 10. The fixing frame 13 is used to prevent the steel bar frame from separating from the arc-shaped frame 10. A second torsion spring 14 is fixedly connected between the fixing frame 13 and the arc-shaped frame 10; a power component, the number of which is the same as the number of the support rods 9, is arranged on the adjusting frame 8 respectively and is used to drive the adjacent arc-shaped frames 10 to rotate.

[0049] Further, as Figures 5-7 shown in the figure, both the arc-shaped frame 10 and the fixing frame 13 are provided with through grooves for reducing the amount of material they push.

[0050] Further, as Figure 7 shown in the figure, the elastic coefficient of the first torsion spring 11 is greater than that of the second torsion spring 14, which is used to make the fixing frame 13 rotate before the arc-shaped frame 10.

[0051] Further, as Figures 4-7 shown in the figure, the power component includes: an electric roller 15, fixedly connected to the adjusting frame 8. A steel wire rope 16 is wound around the electric roller 15. One end of the steel wire rope 16 is fixedly connected to the electric roller 15, and the other end of the steel wire rope 16 is fixedly connected to the adjacent fixing frame 13. The steel wire rope 16 passes through the adjusting frame 8 and the adjacent arc-shaped frame 10.

[0052] The above solution provides a way to limit the steel bar frame and prevent the fixing frame 13 from separating from the arc-shaped frame 10; initially, the fixing frame 13 can be tilted upward to enhance the fixing effect on the steel bar frame. The second torsion spring 14 is used to drive the fixing frame 13 to rotate and reset. Both the arc-shaped frame 10 and the fixing frame 13 are provided with equally spaced through grooves, which are used to allow the concrete to pass through when the arc-shaped frame 10 and the fixing frame 13 rotate, thereby reducing the resistance they receive during rotation. The relationship between the elastic coefficients of the first torsion spring 11 and the second torsion spring 14 is used to make the fixing frame 13 separate from the steel bar frame first when the fixing of the steel bar frame is released, preventing the fixing frame 13 from pushing the steel bar frame to move when the arc-shaped frame 10 drives the fixing frame 13 to rotate, resulting in the deviation of the position of the steel bar frame.

[0053] Workflow: When precast concrete components need to be produced, the staff first convey concrete raw materials into the feeding module 2. The feeding module 2 mixes the concrete raw materials. The staff starts the conveyor belt on the conveying rack 1, and then places the mold on the left side of the conveyor belt on the conveying rack 1 and adjusts its position. The conveyor belt of the conveying rack 1 (for the convenience of description, hereinafter referred to as the conveying rack 1) drives the mold to move to the right. When the mold passes through the spraying module on the conveying rack 1, the spraying module sprays a certain amount of mold release agent onto the inner wall of the mold to facilitate the subsequent separation of the concrete from the mold. Then the mold continues to move to the right until it moves below the feeding module 2. The conveying rack 1 is turned off, and the feeding module 2 is started to convey concrete materials into the mold, gradually filling the mold with concrete. During this process, the staff starts the vibration motor, and the vibration motor drives the mold to vibrate through the conveyor belt on the conveying rack 1. The concrete in the mold spreads around and its upper surface gradually becomes horizontal. When the upper surface of the concrete in the mold approaches the specified height, the vibration motors on the feeding module 2 and the conveying rack 1 are turned off, and the conveying rack 1 is started again to drive the mold to continue moving to the right.

[0054] During the process of the above-mentioned mold continuing to move to the right, when the center line in the vertical direction of the mold aligns with the center line of the lifting frame 7, the conveying rack 1 is turned off, the electric telescopic rod 4 is started and drives the lifting rod 5 to move downward through its telescopic end. The lifting rod 5 drives the lifting frame 7 to move downward through the buffer housing 6. The lifting frame 7 drives the support rod 9 and its parts thereon to move downward through the adjusting frame 8. Taking the moving direction of the right support rod 9 and its parts thereon as a reference hereinafter, the arc-shaped frame 10 and the fixed frame 13 jointly drive the steel bar frame to move downward. The steel bar frame moves downward and gradually approaches the concrete and finally enters the concrete. When the steel bar frame enters the concrete to a specified depth (that is, when the steel bar frame approaches the middle of the concrete), the electric telescopic rod 4 is turned off, and the support rod 9 and its parts all stop moving, and the steel bar frame stops moving.

[0055] After the above-mentioned support rod 9 stops moving downward, the staff starts the vibration module 12 and the electric roller 15. The electric roller 15 winds up the steel wire rope 16, and the steel wire rope 16 pulls the fixed frame 13 to rotate counterclockwise ( Figure 5 , viewed from front to back) and squeezes the surrounding concrete. At the same time, the fixed frame 13 rotates and separates from the steel bar frame and makes the second torsion spring 14 store energy. During this process, part of the concrete replenishes and fixes the steel bar frame to the concrete missing position (that is, the original position of the fixed frame 13) through the through groove of the fixed frame 13. The vibration module 12 drives the fixed frame 13 to vibrate through the support rod 9 and the arc-shaped frame 10, so that the fixed frame 13 drives the surrounding concrete to vibrate, thereby accelerating the speed of its replenishment to the missing position.

[0056] As the fixing frame 13 twists, when the second torsion spring 14 reaches its limit state, the fixing frame 13 stops rotating. The steel wire rope 16 drives the adjacent arc-shaped frame 10 to rotate through the fixing frame 13 and stores energy in the first torsion spring 11. The arc-shaped frame 10 rotates and separates from the steel bar frame. At the same time, part of the concrete is replenished to the concrete missing position through the through groove of the arc-shaped frame 10, preventing the steel bar frame from settling due to the reduction of the fixing force and causing a change in its position. After the first torsion spring 11 reaches its limit position, the arc-shaped frame 10 and its components all stop moving. The electric roller 15 is turned off, and the telescopic end of the electric telescopic rod 4 retracts, causing the driving adjustment frame 8 and its components to move upward and reset. During this process, the vibration module 12 continuously vibrates, enabling the concrete to replenish the positions passed by the arc-shaped frame 10 and the fixing frame 13. When the arc-shaped frame 10 separates from the concrete, the vibration module 12 is turned off, and after the telescopic end of the electric telescopic rod 4 retracts, it automatically turns off. The conveying frame 1 starts to drive the mold to move to the right and send it out.

[0057] After the telescopic end of the electric telescopic rod 4 is fully retracted, the moving frame 3 drives the electric telescopic rod 4 and its components to move forward, causing the adjustment frame 8 to move above the storage rack. The electric telescopic rod 4 starts to drive its components to move downward, causing the arc-shaped frame 10 to move near the upper part of the steel bar frame. The electric roller 15 starts to release the steel wire rope 16. The arc-shaped frame 10 and the fixing frame 13 respectively move in opposite directions under the action of the adjacent first torsion spring 11 and the second torsion spring 14 and fix the adjacent edges of the steel bar frame. Then, the telescopic end of the electric telescopic rod 4 drives the steel bar frame to move upward, and the moving frame 3 drives the electric telescopic rod 4 to move backward and reset. Then, the above process is repeated to place the steel bar frame into the next mold. After the production of the concrete precast member is completed, the staff resets and turns off the opened electrical components.

[0058] Further, as Figure 4 、 Figure 5 and Figure 8 shown, it further includes: a positioning component, arranged on the adjustment frame 8, used to make the position of the adjustment frame 8 correspond to the position of the mold. The positioning component includes: positioning rods 17, multiple in number, all slidably connected to the adjustment frame 8. The positioning rods 17 are fixedly connected with positioning plates 18. An activity cavity for the movement of the adjustment frame 8 is arranged in the lifting frame 7; a tension spring 21, fixedly connected between the lifting frame 7 and the adjustment frame 8; adjustment components, the number of which is the same as the number of positioning rods 17, respectively arranged on adjacent positioning rods 17, used to drive the adjustment frame 8 to move before the steel bar frame completely enters the concrete.

[0059] Further, as Figure 4 and Figure 5 shown, the lower part of the positioning plate 18 is inclined towards the adjustment frame 8, used to make the positioning plate 18 press against the edge of the mold.

[0060] Further, as Figure 4 and Figure 5As shown in the figure, the adjusting assembly includes: a limit ring 20, which is arranged on the positioning rod 17, and a first spring 19 is arranged between the limit ring 20 and the adjusting frame 8.

[0061] The above solution provides a method of driving the adjusting frame 8 to rotate by detecting the edge position of the mold, so that the center line of the steel bar frame coincides with the center line of the mold; the area of the rectangle formed by the upper side edges of the four positioning plates 18 is larger than the area of the mold, and the area of the rectangle formed by the lower side edges of the four positioning plates 18 is smaller than the area of the mold. The movable cavity of the lifting frame 7 is used to vacate the movable space of the adjusting frame 8, so that the adjusting frame 8 can move relative to the lifting frame 7 during the process of placing the steel bar frame to adjust the position of the adjusting frame 8 and its parts thereon; the tension spring 21 is used to drive the adjusting frame 8 to reset, ensuring that the adjusting frame 8 and the lifting frame 7 can move relative to each other; in this embodiment, the limit ring 20 and the positioning rod 17 can be regarded as fixedly connected, and the first spring 19 is used to push the adjusting frame 8 to move upward and reset.

[0062] Workflow: After the above-mentioned mold moves below the adjusting frame 8, the staff starts the electric telescopic rod 4 and repeats the above process to drive the parts thereon to move downward. The adjusting frame 8 drives the positioning plate 18 and its parts thereon to move downward through the positioning rod 17. Hereinafter, the example of the mold tilting forward during the vibration process on the conveying frame 1 is taken.

[0063] As the positioning rod 17 drives the positioning plate 18 to move downward, due to the forward tilt of the mold, the rear positioning plate 18 first contacts the edge of the mold, and the rear positioning plate 18 and the adjacent edge of the mold are mutually extruded, so that the positioning plate 18 drives the adjusting frame 8 and its parts thereon to move forward through the adjacent positioning rod 17. The adjusting frame 8 moves forward relative to the lifting frame 7 and makes the tension spring 21 store energy. Until the front positioning plate 18 contacts the mold, the adjusting frame 8 stops moving forward. At this time, all four positioning plates 18 are in contact with the adjacent edges of the mold to complete the adjustment of the position of the adjusting frame 8, so that the center of the steel bar frame is aligned with the center of the mold.

[0064] After all the above four positioning plates 18 are in contact with the mold, the positioning plate 18 and its parts thereon stop moving downward. The adjusting frame 8 drives the parts thereon to move downward relative to the positioning plate 18 and compress the first spring 19. Until the steel bar frame enters the concrete to the specified depth, the electric telescopic rod 4 is turned off, and the electric roller 15 is started and repeats the above process to release the fixation of the steel bar frame. Then the electric telescopic rod 4 is started to make the adjusting frame 8 drive the parts thereon to reset. During this process, the extrusion force received by the first spring 19 decreases and it stretches, so that the positioning rod 17 moves downward relative to the adjusting frame 8. Until the first spring 19 is fully stretched, the positioning rod 17 drives the positioning plate 18 to move upward and reset together with the adjusting frame 8. When all four positioning plates 18 are separated from the mold, the tension spring 21 drives the adjusting frame 8 to move backward and reset relative to the lifting frame 7.

[0065] Further, asFigure 8 and Figure 9 As shown in Figure 9 , it further includes a separation component arranged on the lifting rod 5 for adjusting the extrusion force received by the lifting frame 7. The separation component includes a limit rod 22 slidably connected to the lifting rod 5. The lifting rod 5 is slidably connected to the buffer housing 6. A second spring 23 is fixedly connected between the limit rod 22 and the lifting rod 5. A limit hole is provided in the buffer housing 6, and the position of the lifting rod 5 is fixed by the limit rod 22 passing through the limit hole of the buffer housing 6. The positioning rod 17 is provided with a threaded portion, and the limit ring 20 is threadedly connected to the adjacent positioning rod 17. The limit ring 20 is used to limit the moving distance of the adjusting frame 8.

[0066] Further, as Figure 8 and Figure 9 shown in Figure 9 , a communication hole 24 is provided on the lifting rod 5, and a flowing medium is filled in the buffer housing 6. The communication hole 24 is used to enable the flowing medium to slowly flow in the buffer housing 6.

[0067] The above solution provides a method for adjusting the pressing distance of the adjusting frame 8 after the height of the mold changes due to the concrete remaining on the conveyor belt of the conveyor frame 1. The second spring 23 is always in a compressed state, used to extrude the limit rod 22, so that the positions of the lifting rod 5 and the buffer housing 6 remain relatively stable during the normal movement of the adjusting frame 8. One end of the limit rod 22 away from the axis of the lifting rod 5 is hemispherical, so that the limit rod 22 can be separated from the limit hole of the buffer housing 6 when being extruded. The flowing medium in the buffer housing 6 is hydraulic oil. The communication hole 24 is used to enable the lifting rod 5 and the buffer housing 6 to move relatively slowly, preventing the first spring 19 from pushing the adjusting frame 8 to rebound quickly, resulting in too large a deviation in the position of the support rod 9. In this embodiment, the limit ring 20 and the positioning rod 17 are threadedly connected, and the position of the limit ring 20 on the positioning rod 17 is adjusted to adapt to molds of different heights, improving the applicable range of the device. Initially, take the limit ring 20 being located at the lower part of the threaded portion on the positioning rod 17 as an example.

[0068] Workflow: Before producing the concrete precast parts as described above, the staff rotates the limit ring 20 to move it upward, thereby adjusting the distance between the limit ring 20 and the adjusting frame 8 to make the distance between the limit ring 20 and the adjusting frame 8 close to half of the mold depth. During this process, the first spring 19 is gradually compressed. After the position of the limit ring 20 is adjusted, the staff activates the electric telescopic rod 4. The telescopic end of the electric telescopic rod 4 drives the lifting rod 5 to move downward. The lifting rod 5 drives the buffer housing 6 to move downward through the limit rod 22. The buffer housing 6 drives the lifting frame 7 and the parts thereon to move downward by repeating the above process, so that the positioning plate 18 adjusts the position of the adjusting frame 8. When all four positioning plates 18 are in contact with the mold, the positioning plate 18 and the parts thereon stop moving. The adjusting frame 8 moves downward relative to the positioning rod 17 again and compresses the first spring 19, so that the support rod 9 drives the steel bar frame to move downward into the concrete through the arc-shaped frame 10 until the first spring 19 can no longer be compressed, and then the adjusting frame 8 stops moving and the lifting frame 7 stops moving.

[0069] After the adjusting frame 8 stops moving as described above, due to the accumulation of concrete on the conveying frame 1 causing the mold to be lifted, the telescopic end of the electric telescopic rod 4 does not extend to the specified position. The telescopic end of the electric telescopic rod 4 continues to drive the lifting rod 5 to move downward, increasing the extrusion force between the limit rod 22 and the adjacent limit holes of the buffer housing 6, so that the limit rod 22 enters the lifting rod 5 and compresses the adjacent second spring 23 until the limit rod 22 separates from the adjacent limit holes of the buffer housing 6. The limit rod 22 releases the limit on the lifting rod 5 and the buffer housing 6, so that the lifting rod 5 no longer rigidly extrudes the buffer housing 6 through the limit rod 22, preventing the positioning plate 18 from excessively squeezing the mold, resulting in damage to the device and the mold and affecting the normal production of concrete precast parts.

[0070] After the above-mentioned limiting rod 22 releases the limitation on the lifting rod 5 and the buffer housing 6, the lifting rod 5 drives the limiting rod 22 to move downward relative to the buffer housing 6, and the hydraulic oil in the buffer housing 6 flows through the communication hole 24, so that the lifting rod 5 still has a downward thrust on the buffer housing 6, preventing the buffer housing 6 from driving the parts thereon to quickly rebound under the action of the first spring 19, resulting in a change in the position of the steel bar rack. Until the telescopic end of the electric telescopic rod 4 extends to a specified length, the lifting rod 5 stops moving downward. During this process, when the limiting rod 22 is separated from the adjacent limiting hole of the buffer housing 6, the staff starts the electric roller 15 to retract the steel wire rope 16, so that the arc-shaped frame 10 rotates and releases the fixation of the steel bar rack. Then the electric telescopic rod 4 starts and drives the lifting rod 5 to move upward. The first spring 19 drives the lifting frame 7 and the parts thereon to move upward by pushing the adjusting frame 8 until the first spring 19 extends, and the lifting frame 7 stops moving. The lifting rod 5 drives the limiting rod 22 to move upward relative to the buffer housing 6, so that the limiting rod 22 enters the limiting hole of the buffer housing 6 again under the push of the second spring 23 to complete the reset. Then the lifting rod 5 drives the lifting frame 7 and the upper parts to continue to move upward through the limiting rod 22 and the buffer housing 6, thus completing the reset of the device.
