Description

Technical Field

[0001] The invention relates to the technical field of concrete molding, and in particular to a concrete molding device for construction engineering. Background Art

[0002] Concrete is a composite material made of cement as a binder, 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, prefabricated concrete parts are often used to reduce the impact of uncertain factors such as weather on the construction progress. When existing concrete forming devices produce prefabricated parts, the general process is as follows: first, pour the mixed concrete slurry into the specified mold, then place a steel frame in the mold filled with concrete to enhance the strength of the prefabricated part, then wait for the concrete to solidify, and finally demold and remove it.

[0003] However, in the process of placing the steel frame, the existing process usually places the steel frame directly on the concrete surface in the mold, and then makes it gradually sink into the concrete through continuous vibration. However, in this process, due to the lack of effective support for the steel frame, the settlement speed of each part of the steel frame is inconsistent, which can easily lead to uneven distribution inside the concrete and even excessive settlement. This will not only cause differences in the strength of various parts of the concrete after solidification, but also significantly affect the overall quality of the concrete precast parts. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] A concrete forming device for construction engineering, such as Figure 1-Figure 7 As 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.

[0022] 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.

[0023] Further, such as Figure 4-Figure 7 As shown, the fixing assembly includes: a fixing frame 13, which is hinged to the arc frame 10, and the fixing frame 13 is used to prevent the steel frame from separating from the arc frame 10, and a second torsion spring 14 is fixedly connected between the fixing frame 13 and the arc frame 10; a power assembly, the number of which is the same as the number of the support rods 9, and both are arranged on the adjustment frame 8, and are respectively used to drive the adjacent arc frames 10 to rotate.

[0024] Further, such as Figure 5-Figure 7 As shown, the arc frame 10 and the fixed frame 13 are both provided with through slots for reducing the amount of materials pushed by them.

[0025] Further, such as Figure 7 As shown, the elastic coefficient of the first torsion spring 11 is greater than the elastic coefficient of the second torsion spring 14 , so as to enable the fixing frame 13 to rotate before the arc frame 10 .

[0026] Further, such as Figure 4-Figure 7As shown, the power assembly includes: an electric roller 15, which is fixed to the adjusting frame 8, and a steel wire rope 16 is wound around the electric roller 15, and one end of the steel wire rope 16 is fixed to the electric roller 15, and the other end of the steel wire rope 16 is fixed to the adjacent fixed frame 13, and the steel wire rope 16 passes through the adjusting frame 8 and the adjacent arc frame 10.

[0027] The above scheme provides a way to limit the steel frame and prevent the fixing frame 13 from separating from the arc frame 10; initially, the fixing frame 13 can be deflected upward to strengthen the fixing effect of the steel frame, and the second torsion spring 14 is used to drive the fixing frame 13 to rotate and reset. The arc frame 10 and the fixing frame 13 are both provided with equidistantly distributed through grooves, which are used to allow concrete to pass through when the arc frame 10 and the fixing frame 13 rotate, thereby reducing the resistance encountered during rotation. The relationship between the elastic coefficients of the first torsion spring 11 and the second torsion spring 14 is used to separate the fixing frame 13 from the steel frame first when the steel frame is released, so as to prevent the fixing frame 13 from pushing the steel frame to move when the arc frame 10 drives the fixing frame 13 to rotate, resulting in a deflection in the position of the steel frame.

[0028] Workflow: When it is necessary to produce prefabricated concrete parts, the staff first transports the concrete raw materials into the unloading module 2. The unloading module 2 mixes the concrete raw materials. The staff starts the conveyor belt on the conveyor frame 1, and then places the mold on the left side of the conveyor belt on the conveyor frame 1 and adjusts its position. The conveyor belt of the conveyor frame 1 (for the convenience of expression, the conveyor frame 1 is referred to as the conveyor frame 1 below) drives the mold to move to the right. When the mold passes through the spraying module on the conveyor frame 1, the spraying module sprays a certain amount of release agent on the inner wall of the mold to facilitate the subsequent separation of the concrete from the mold. After that, the mold continues to move to the right until the mold moves below the unloading module 2. The conveyor frame 1 is closed, the unloading module 2 is started and the concrete material is transported into the mold, so that the concrete gradually fills the mold. In this process, the staff starts the vibration motor, and the vibration motor drives the mold to vibrate through the conveyor belt on the conveyor frame 1. The concrete in the mold spreads to the surroundings and makes its upper side gradually horizontal. When the upper surface of the concrete in the mold approaches the specified height, the unloading module 2 and the vibration motor on the conveyor frame 1 are closed, and the conveyor frame 1 is started again to drive the mold to continue to move to the right.

[0029] In the process of the above-mentioned mold continuing to move to the right, when the center line of the mold in the vertical direction is aligned with the center line of the lifting frame 7, the conveying frame 1 is closed, the electric telescopic rod 4 is started and drives the lifting rod 5 to move downward through its telescopic end, and the lifting rod 5 drives the lifting frame 7 to move downward through the buffer shell 6. The lifting frame 7 drives the support rod 9 and the parts thereon to move downward through the adjustment frame 8. The following text takes the moving direction of the right support rod 9 and the parts thereon as a reference. The arc frame 10 and the fixed frame 13 jointly drive the steel frame to move downward. The steel frame moves downward and gradually approaches the concrete and finally enters the concrete. When the steel frame enters the specified depth in the concrete (that is, when the steel frame is close to the middle of the concrete), the electric telescopic rod 4 is closed, the support rod 9 and the parts thereon stop moving, and the steel frame stops moving.

[0030] After the support rod 9 stops moving downward, the staff starts the vibration module 12 and the electric roller 15, the electric roller 15 reels the wire rope 16, and the wire rope 16 pulls the fixing frame 13 to rotate counterclockwise ( Figure 5 , viewed from the front to the back) and squeezes the surrounding concrete, while the fixing frame 13 rotates and separates from the steel frame and causes the second torsion spring 14 to store force. During this process, part of the concrete passes through the through groove of the fixing frame 13 to supplement the concrete missing position (i.e., the original position of the fixing frame 13). The vibration module 12 drives the fixing frame 13 to vibrate through the support rod 9 and the arc frame 10, so that the fixing frame 13 drives the surrounding concrete to vibrate, thereby accelerating its speed of supplementing to the missing position.

[0031] As the fixed frame 13 twists, when the second torsion spring 14 reaches the limit state, the fixed frame 13 stops rotating, the steel wire rope 16 drives the adjacent arc frame 10 to rotate through the fixed frame 13 and makes the first torsion spring 11 accumulate force, the arc frame 10 rotates and separates from the steel frame, and at the same time, part of the concrete is supplemented to the missing position of the concrete through the through groove of the arc frame 10 to prevent the steel frame from settling due to the reduction of the fixing force and causing its position to change. After the first torsion spring 11 reaches the limit position, the arc frame 10 and its parts stop moving, the electric roller 15 is closed, and the telescopic end of the electric telescopic rod 4 is retracted, so that the adjusting frame 8 and its parts are driven to move upward and reset. During this process, the vibration module 12 continues to vibrate, so that the concrete supplements the position where the arc frame 10 and the fixed frame 13 pass. When the arc frame 10 is separated from the concrete, the vibration module 12 is closed, and the telescopic end of the electric telescopic rod 4 is automatically closed after being retracted, and the conveying frame 1 starts to drive the mold to move to the right and send it out.

[0032] After the telescopic end of the electric telescopic rod 4 is fully retracted, the movable frame 3 drives the electric telescopic rod 4 and the parts thereon to move forward, so that the adjusting frame 8 moves to the top of the material storage frame, and the electric telescopic rod 4 starts to drive the parts thereon to move downward, so that the arc frame 10 moves to the vicinity of the upper part of the steel frame, and the electric roller 15 starts to release the wire rope 16. The arc frame 10 and the fixed frame 13 respectively move in opposite directions and fix the adjacent edges of the steel frame under the action of the adjacent first torsion spring 11 and the second torsion spring 14, and then the telescopic end of the electric telescopic rod 4 drives the steel frame to move upward, and the movable frame 3 drives the electric telescopic rod 4 to move backward and reset, and then repeats the above process to place the steel frame in the next mold. After the production of the precast concrete parts is completed, the staff will reset and turn off the turned-on electrical components.

[0033] Further, such as Figure 4 , Figure 5 and Figure 8 As shown, it also includes: a positioning component, which is arranged on the adjustment frame 8 and is used to make the position of the adjustment frame 8 correspond to the mold position. The positioning component includes: a plurality of positioning rods 17, which are all slidably connected to the adjustment frame 8, the positioning rods 17 are fixedly connected to the positioning plates 18, and a movable cavity for the adjustment frame 8 to move is arranged in the lifting frame 7; a tension spring 21 is fixedly connected between the lifting frame 7 and the adjustment frame 8; the adjusting components, the number of which is the same as the number of positioning rods 17, are respectively arranged on adjacent positioning rods 17, and are used to drive the adjustment frame 8 to move before the steel frame completely enters the concrete.

[0034] Further, such as Figure 4 and Figure 5 As shown, the lower portion of the positioning plate 18 is tilted toward the adjusting frame 8 so as to enable the positioning plate 18 to press the edge of the mold.

[0035] Further, such as Figure 4 and Figure 5 As shown, the adjustment component includes: a limiting ring 20 arranged on the positioning rod 17, and a first spring 19 is arranged between the limiting ring 20 and the adjustment frame 8.

[0036] The above scheme provides a method of detecting the edge position of the mold and driving the adjusting frame 8 to rotate so that the center line of the steel frame coincides with the center line of the mold; the area of ​​the rectangle surrounded by the upper edges of the four positioning plates 18 is larger than the area of ​​the mold, and the area of ​​the rectangle surrounded by the lower 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 clear the movable space of the adjusting frame 8, so that the adjusting frame 8 can move relative to the lifting frame 7 during the placement of the steel frame, and the position of the adjusting frame 8 and the parts thereon can be adjusted; 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.

[0037] Workflow: After the above-mentioned mold moves to the bottom of the adjustment frame 8, the staff starts the electric telescopic rod 4 and repeats the above process to drive the parts on it to move downward. The adjustment frame 8 drives the positioning plate 18 and the parts on it to move downward through the positioning rod 17. The following takes the forward deflection of the mold during the vibration process on the conveyor frame 1 as an example.

[0038] As the positioning rod 17 drives the positioning plate 18 to move downward, due to the forward deflection 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 squeeze each other, so that the positioning plate 18 drives the adjustment frame 8 and the parts thereon to move forward through the adjacent positioning rod 17. The adjustment frame 8 moves forward relative to the lifting frame 7 and the tension spring 21 accumulates force until the front positioning plate 18 contacts the mold, and the adjustment frame 8 stops moving forward. At this time, the four positioning plates 18 are in contact with the adjacent edges of the mold to complete the adjustment of the position of the adjustment frame 8, so that the center of the steel frame is aligned with the center of the mold.

[0039] After the above four positioning plates 18 are in contact with the mold, the positioning plate 18 and the parts thereon stop moving downward, and the adjusting frame 8 drives the parts thereon to move downward relative to the positioning plate 18 and compresses the first spring 19, until the steel frame enters the concrete to a specified depth, the electric telescopic rod 4 is closed, the electric roller 15 is started and the above process is repeated to release the fixation of the steel frame, and 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 exerted on the first spring 19 is reduced and stretched, 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, and when the four positioning plates 18 are separated from the mold, the tension spring 21 drives the adjusting frame 8 to move backward relative to the lifting frame 7 to reset.

[0040] Further, such as Figure 8 and Fig. 9 As shown, it also includes: a separation component, which is arranged on the lifting rod 5 and is used to adjust the extrusion force exerted on the lifting frame 7. The separation component includes: a limit rod 22, which is slidably connected to the lifting rod 5. The lifting rod 5 is slidably connected to the buffer shell 6. A second spring 23 is fixedly connected between the limit rod 22 and the lifting rod 5. A limit hole is arranged in the buffer shell 6. The limit hole of the buffer shell 6 fixes the position of the lifting rod 5 through the limit rod 22. The positioning rod 17 is provided with a threaded portion. 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 adjustment frame 8.

[0041] Further, such as Figure 8 and Fig. 9 As shown, a connecting hole 24 is provided on the lifting rod 5 , and the buffer shell 6 is filled with a flowing medium. The connecting hole 24 is used to allow the flowing medium to flow slowly in the buffer shell 6 .

[0042] The above scheme provides a method for adjusting the downward pressure distance of the adjusting frame 8 after concrete remains on the conveyor belt of the conveying frame 1 causing the mold height to change; the second spring 23 is always in a compressed state, used to squeeze the limit rod 22, so that the position of the lifting rod 5 and the buffer shell 6 of the adjusting frame 8 remains relatively stable during normal movement, and the 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 shell 6 when squeezed, and the flow medium in the buffer shell 6 is hydraulic oil. The connecting hole 24 is used to make the lifting rod 5 and the buffer shell 6 move slowly relative to each other to prevent the first spring 19 from pushing the adjusting frame 8 to rebound quickly, resulting in excessive deviation in the position of the support rod 9. In this embodiment, the limit ring 20 is threadedly connected to the positioning rod 17. The position of the limit ring 20 on the positioning rod 17 is adjusted to adapt to molds of different heights, thereby improving the scope of application of the device. Initially, the limit ring 20 is located at the lower part of the threaded part on the positioning rod 17 as an example.

[0043] Working process: before the above-mentioned production of precast concrete parts, the staff rotates the limit ring 20 to move it upward, and then adjusts the distance between the limit ring 20 and the adjusting frame 8, so that the distance between the limit ring 20 and the adjusting frame 8 is close to half of the mold depth. In this process, the first spring 19 is gradually compressed. After the position adjustment of the limit ring 20 is completed, the staff starts the electric telescopic rod 4, and the telescopic end of the electric telescopic rod 4 drives the lifting rod 5 to move downward. The lifting rod 5 drives the buffer shell 6 to move downward through the limit rod 22. The buffer shell 6 repeats the above process to drive the lifting frame 7 and the parts thereon to move downward, so that the positioning plate 18 adjusts the position of the adjusting frame 8. When the four positioning plates 18 are in contact with the mold, the positioning plates 18 and the parts thereon stop moving, and the adjusting frame 8 moves downward again relative to the positioning rod 17 and compresses the first spring 19, so that the support rod 9 drives the steel frame to move downward through the arc frame 10 into the concrete. Until the first spring 19 can no longer be compressed, the adjusting frame 8 stops moving and the lifting frame 7 stops moving.

[0044] After the above-mentioned adjustment frame 8 stops moving, the mold is lifted due to the accumulation of concrete on the conveying frame 1, and 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, thereby increasing the extrusion force between the limit rod 22 and the adjacent limit holes of the buffer shell 6, so that the limit rod 22 enters the lifting rod 5 and compresses the adjacent second spring 23 until the limit rod 22 is separated from the adjacent limit holes of the buffer shell 6. The limit rod 22 releases the limit on the lifting rod 5 and the buffer shell 6, so that the lifting rod 5 no longer hard squeezes the buffer shell 6 through the limit rod 22, thereby preventing the positioning plate 18 from excessively squeezing the mold, causing damage to the device and the mold, and affecting the normal production of concrete precast parts.

[0045] After the limit rod 22 releases the limit on the lifting rod 5 and the buffer shell 6, the lifting rod 5 drives the limit rod 22 to move downward relative to the buffer shell 6, and the hydraulic oil in the buffer shell 6 flows through the connecting hole 24, so that the lifting rod 5 still has a downward thrust on the buffer shell 6, preventing the buffer shell 6 from driving the parts thereon to rebound quickly under the action of the first spring 19, causing the position of the steel frame to change, 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 limit rod 22 is separated from the adjacent limit hole of the buffer shell 6, the staff starts the electric roller 15 to retract the steel wire Rope 16 makes the arc frame 10 rotate and releases the fixation to the steel frame, 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 is extended, the lifting frame 7 stops moving, the lifting rod 5 drives the limiting rod 22 to move upward relative to the buffer shell 6, so that the limiting rod 22 enters the limiting hole of the buffer shell 6 again under the push of the second spring 23 to complete the reset, and 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 shell 6, thereby completing the reset of the device.

[0046] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
