Description

Technical Field

[0001] This invention relates to the field of energy-saving building materials production, specifically to an energy-saving concrete precast component placement device and its molding method for roadbed protection and drainage engineering. Background Technology

[0002] Subgrade protection and drainage engineering plays a vital role in infrastructure construction. It not only effectively prevents rainwater erosion of the subgrade but also ensures its stability and service life, which is crucial for maintaining road traffic capacity and safety.

[0003] In the construction of roadbed protection and drainage projects, energy-saving building materials (precast components) are often required. These energy-saving building materials are mostly made of concrete, which, due to its high strength and durability, can well adapt to complex construction environments and long-term service requirements. With increasing environmental awareness and technological advancements, energy-saving precast concrete components are gradually gaining popularity. These precast components place greater emphasis on resource conservation and efficient energy utilization during production, not only aligning with the concept of sustainable development but also reducing production costs to some extent.

[0004] Taking a common U-shaped energy-saving precast concrete component as an example, its production requires the use of a specific mold. The mold's forming cavity is an inverted U-shape, with a groove of a certain width (used in conjunction with a cover plate) and deep grooves on both sides. However, in actual production, after the concrete is delivered to the mold, workers often need to manually push the concrete into the deep grooves on both sides and vibrate it. This method has many drawbacks: firstly, manual operation is not only labor-intensive but also inefficient; secondly, during operation, due to the narrow width of the deep grooves, the flow of concrete within them is restricted, making it difficult to ensure that the deep grooves are completely filled, easily leading to the formation of air bubbles and voids, thus affecting the density and strength of the precast component. Simultaneously, the vibrator operating within the deep grooves may impact and damage the mold, especially for complex shapes such as the inverted U-shape, potentially causing mold deformation or damage, posing a risk to project quality. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving concrete precast component placement device and its molding method for roadbed protection and drainage engineering, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The energy-saving precast concrete placement device for roadbed protection and drainage engineering includes a frame and a crossbeam that can move along the length of the frame, and also includes:

[0008] A vertical arm is slidably mounted on the cross frame. A shaft is provided at the bottom of the vertical arm. Two assembly plates are rotatably connected to the shaft. Vibrating rods are provided on both sides of the assembly plates. The two assembly plates form a V-shaped material-pushing plate group. The V-shaped material-pushing plate group moves along the length of the frame and pushes the concrete in the middle of the mold into the deep grooves on both sides of the mold. Whenever the V-shaped material-pushing plate group reaches the end of its stroke, the driven mechanism on the vertical arm drives the two assembly plates to deflect synchronously but in different directions so that the protruding part of the V-shaped material-pushing plate group always faces the direction of movement.

[0009] The discharge head is located below the cross frame and is connected to a concrete conveying pipeline. The cross frame is equipped with a power mechanism to drive the concrete conveying pipeline to deflect the discharge head. The driven mechanism is triggered when the discharge head deflects, and the discharge head is always located on one side of the protruding part of the V-shaped material guide plate assembly.

[0010] As a further aspect of the present invention: a cylinder is rotatably mounted on the crossbeam, the movable end of the cylinder is hinged to the end of the vertical arm away from the shaft, and the cylinder is used to drive the vertical arm to rise and fall relative to the crossbeam so that the V-shaped material feeding plate assembly moves away from or closer to the mold surface.

[0011] As a further embodiment of the present invention: a connecting plate is provided on the side of the boom, the concrete conveying pipeline includes a riser rotatably connected to the connecting plate and a bend fixedly connected to the riser and the discharge head, the bend is connected to the driven mechanism, and the riser is connected to the power mechanism.

[0012] As a further embodiment of the present invention: a support arm is slidably provided on the cross frame, the support arm is able to slide up and down relative to the cross frame, and a guide tube is provided at the upper end of the support arm, the guide tube is rotatably and sealed to the riser, and the guide tube is connected to an external concrete pump.

[0013] As a further embodiment of the present invention: the power mechanism includes a first gear rotatably mounted on the crossbeam and a drive motor mounted at the bottom of the crossbeam, the output end of the drive motor being connected to the shaft of the first gear, and the first gear being connected to the vertical pipe through a transmission structure.

[0014] As a further embodiment of the present invention: the transmission structure includes a drive tube rotatably mounted on the crossbeam and a second gear fixed on the drive tube, the second gear meshing with the first gear, and the vertical tube slidingly fitted with the drive tube;

[0015] The riser has two strip-shaped protrusions on its outer wall and two strip-shaped grooves on its inner wall. The strip-shaped grooves are adapted to the strip-shaped protrusions and are parallel to the central axis of the drive pipe and the riser.

[0016] As a further embodiment of the present invention: the driven mechanism includes a sliding engagement component disposed on the upright arm, the sliding engagement component being able to move relative to the upright arm when the bent tube rotates, and each of the two assembly plates being connected to the sliding engagement component through a set of transmission structures.

[0017] As a further embodiment of the present invention: the sliding fit assembly includes two columns respectively fixed on both sides of the upright arm, two sleeves respectively slidably sleeved on the two columns, and an arc-shaped member fixedly connecting the two sleeves, wherein the arc-shaped member is concentric with the upright pipe;

[0018] The arc-shaped component has a groove, and the bent pipe has a drive column. The drive column passes through the groove and is slidably connected to the arc-shaped component. The groove includes a first through groove and a second through groove connected to each other. The first through groove is spirally arranged, and the second through groove is arc-shaped.

[0019] As a further embodiment of the present invention: the transmission structure includes a guide rail fixed to the side of the upright arm, a slider slidably disposed on the guide rail, and a connecting rod disposed between the slider and the sleeve, wherein the two ends of the connecting rod are respectively hinged to the sleeve and the slider;

[0020] The assembly plate is provided with a driven plate, the side of the slider is provided with a follower elbow, the driven plate is provided with a slide groove adapted to the follower elbow, and the end of the follower elbow away from the slider extends into the slide groove and is slidably connected to the driven plate.

[0021] The molding method for energy-saving precast concrete components in roadbed protection and drainage engineering, using the aforementioned material placement device, includes the following steps:

[0022] Step 1: Clean the molding molds for energy-saving building materials;

[0023] Step 2: The material is laid out, and the discharge head and V-shaped material-pushing plate assembly move back and forth on the mold. After reaching the end point of the movement, the power mechanism drives the discharge head to change its position. The driven mechanism is triggered, causing the two assembly plates to swing synchronously but in opposite directions. This ensures that the protruding part of the V-shaped material-pushing plate assembly always faces the direction of movement, and that the discharge head is always located on one side of the protruding part of the V-shaped material-pushing plate assembly. When the V-shaped material-pushing plate assembly moves on the upper part of the mold, it pushes the concrete into the deep grooves on both sides of the mold, and the vibrator compacts the concrete.

[0024] Step 3: After the concrete in the deep grooves on both sides of the mold is filled, the vertical arm rises intermittently to fill the space between the two deep grooves with concrete as a connection.

[0025] Step four: Install the cover plate on top of the mold. After the concrete has formed, disassemble the mold to obtain a U-shaped energy-saving building material.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This invention uses two assembly plates that can swing synchronously but in opposite directions. The two assembly plates are kept in an inclined state, which can form a V-shaped material-pulling plate group. Utilizing its "V" shape design and the set vibrating rod, the concrete can be divided and pushed into the deep grooves on both sides of the mold.

[0028] On the one hand, it realizes automated material distribution in the production of energy-saving building materials, improving production efficiency. On the other hand, the V-shaped material feeding plate group moves back and forth multiple times on the upper part of the mold, filling the deep groove of the mold layer by layer. This makes the concrete filling a gradual process. In conjunction with the use of vibrators, it avoids the problem of restricted concrete flow, ensuring the complete filling of the deep groove of the mold and avoiding the generation of air bubbles and voids. This improves the density and strength of energy-saving building materials. Moreover, with this material distribution method, the vibrator compacts the concrete while distributing the material, eliminating the need for the vibrator to enter the deep groove of the mold after distribution. This avoids impact damage to the mold and the problem of affecting the mold's precision, thus ensuring the quality of energy-saving building material projects. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0042] Please see Figures 1-10In this embodiment of the invention, the energy-saving concrete precast component placement device for roadbed protection and drainage engineering includes a frame 1 and a cross frame 3 that can move along the length of the frame 1. In actual operation, a walking wheel can be installed at the bottom of the frame 1. This device can move between multiple energy-saving building material molding molds arranged in the production workshop and place the material on the multiple molds in sequence.

[0043] The energy-saving precast concrete placement device for the roadbed protection and drainage project also includes:

[0044] The vertical arm 5 is slidably mounted on the cross frame 3. The bottom end of the vertical arm 5 is provided with a shaft 501. The shaft 501 is rotatably connected to two assembly plates 6. Both sides of the assembly plates 6 are provided with vibrating rods 7. The two assembly plates 6 form a V-shaped material-pushing plate group. The V-shaped material-pushing plate group moves along the length direction of the frame 1 and pushes the concrete in the middle part of the mold into the deep grooves on both sides of the mold. Whenever the V-shaped material-pushing plate group reaches the end of its stroke, the driven mechanism on the vertical arm 5 drives the two assembly plates 6 to deflect synchronously but in different directions so that the protruding part of the V-shaped material-pushing plate group always faces the direction of movement.

[0045] The discharge head 4 is located below the cross frame 3. The discharge head 4 is connected to the concrete conveying pipeline. The cross frame 3 is equipped with a power mechanism to drive the concrete conveying pipeline to deflect the discharge head 4. The driven mechanism is triggered when the discharge head 4 deflects. The discharge head 4 is always located on one side of the protruding part of the V-shaped material guide plate group.

[0046] It should be noted that two sets of opposing linear drive modules 2 are provided on the frame 1, and the two ends of the crossbeam 3 are respectively connected to the two sets of linear drive modules 2. The linear drive module 2 is an application of existing technology, that is, the crossbeam 3 is driven by a servo motor and a lead screw (the specific structure will not be described in detail in this application), so that the V-shaped material-pulling plate group can move along the length direction of the frame 1 (that is, along the length direction of the deep grooves on both sides of the mold) on the upper part of the mold. This driving method of servo motor and lead screw can effectively ensure the stability of the movement of the V-shaped material-pulling plate group, thereby improving the precision of the V-shaped material-pulling plate group in the concrete processing process.

[0047] Specifically, during operation, the V-shaped material-pushing plate assembly moves to one side on the upper part of the mold, and the discharge head 4 is located on one side of the protruding part of the V-shaped material-pushing plate assembly. The concrete is transported through the concrete conveying pipeline and through the discharge head 4 to the middle part of the mold. Then, the V-shaped material-pushing plate assembly passes through the concrete, and due to its "V" shape design, it has a separating effect on the concrete, causing the concrete to be pushed to both sides and finally enter the deep grooves on both sides of the mold.

[0048] After the V-shaped material-pulling plate assembly reaches the end of its stroke, the power mechanism drives the concrete conveying pipeline to swing the discharge head 4 and change direction. At the same time, the driven mechanism is triggered, driving the two assembly plates 6 to swing synchronously but in different directions. Subsequently, the V-shaped material-pulling plate assembly moves to the other side on the upper part of the mold. After the V-shaped material-pulling plate assembly moves back and forth on the upper part of the mold multiple times, the concrete is filled into the deep grooves on both sides of the mold layer by layer. During the process of the V-shaped material-pulling plate assembly moving the concrete, the concrete passes through the vibrator 7. The vibrator 7 can vibrate the concrete, increase the fluidity of the concrete, and prevent air bubbles from entering the mold.

[0049] To address this, the present invention provides two assembly plates 6 that can swing synchronously but in opposite directions. The two assembly plates 6 are kept in an inclined state, forming a V-shaped material-pushing plate group. Utilizing its "V" shape design and the provided vibrating rod 7, the concrete can be divided and pushed into the deep grooves on both sides of the mold.

[0050] On the one hand, it realizes automated material distribution in the production of energy-saving building materials, improving production efficiency. On the other hand, the V-shaped material feeding plate group moves back and forth multiple times on the upper part of the mold, filling the deep groove on the mold layer by layer. This makes the concrete filling a gradual process. In conjunction with the use of the vibrator 7, it avoids the problem of restricted concrete flow, ensuring the complete filling of the deep groove of the mold and avoiding the generation of air bubbles and voids. This improves the density and strength of the energy-saving building materials. Moreover, with this material distribution method, the vibrator 7 vibrates the concrete while distributing it, eliminating the need for the vibrator 7 to enter the deep groove of the mold after the distribution is completed. This avoids impact damage to the mold and the problem of affecting the mold's precision, thus ensuring the quality of the energy-saving building material project.

[0051] Please refer to it again. Figure 5 A cylinder 12 is rotatably mounted on the cross frame 3. The movable end of the cylinder 12 is hinged to the end of the vertical arm 5 away from the shaft 501. The cylinder 12 is used to drive the vertical arm 5 to rise and fall relative to the cross frame 3 so that the V-shaped material feeding plate group moves away from or closer to the mold surface.

[0052] In specific implementation, the cylinder 12 can also be replaced by a hydraulic cylinder. This application does not make specific limitations on this, as long as the driving requirements are met, and the choice can be made according to the actual situation.

[0053] Specifically, during the material laying process, the cylinder 12 can drive the vertical arm 5 to rise and fall relative to the horizontal frame 3. As the number of times the V-shaped material-pulling plate group moves back and forth on the mold surface increases, after the deep grooves on both sides of the mold are filled with concrete, the movable end of the cylinder 12 needs to extend to control the vertical arm 5 to drive the V-shaped material-pulling plate group and the discharge head 4 to lift intermittently, so as to fill the two deep grooves with concrete as a connection, thereby forming a U-shaped precast component.

[0054] Please refer to it again. Figure 9 The side of the boom 5 is provided with a connecting plate 502. The concrete conveying pipeline includes a riser 10 rotatably connected to the connecting plate 502 and a bend 9 fixedly connected to the riser 10 and the discharge head 4. The bend 9 is connected to the driven mechanism, and the riser 10 is connected to the power mechanism.

[0055] Please refer to it again. Figure 5 and Figure 6 The cross frame 3 is also slidably provided with a support arm 301, which can slide up and down relative to the cross frame 3. The upper end of the support arm 301 is provided with a conduit 11, which is sealed and rotatably connected to the riser 10. The conduit 11 is connected to an external concrete pump.

[0056] When the cylinder 12 drives the vertical arm 5 to slide upward on the cross frame 3, the vertical arm 5 can drive the riser 10 to rise together through the connecting plate 502. Correspondingly, the guide tube 11 rises together with the riser 10, and the support arm 301 slides relative to the cross frame 3.

[0057] The support arm 301 provides positional support and fixation for the guide pipe 11. In specific implementation, the external concrete pump is connected to the guide pipe 11 through a hose. When the V-shaped material-pushing plate group moves back and forth, the external concrete pump pumps the concrete. The concrete passes through the guide pipe 11, the riser 10, the bend 9, and the discharge head 4 in sequence to reach the middle part of the mold. Then, it is pushed to both sides of the mold by the V-shaped material-pushing plate group and is vibrated by the vibrator 7.

[0058] Please refer to it again. Figure 5 and Figure 9The power mechanism includes a first gear 14 rotatably mounted on the crossbeam 3 and a drive motor 13 mounted at the bottom of the crossbeam 3. The output end of the drive motor 13 is connected to the shaft of the first gear 14. The first gear 14 is connected to the riser 10 through a transmission structure. The transmission structure includes a drive tube 23 rotatably mounted on the crossbeam 3 and a second gear 15 fixed on the drive tube 23. The second gear 15 meshes with the first gear 14, and the riser 10 is slidably fitted with the drive tube 23. The outer wall of the riser 10 is provided with two strip-shaped protrusions 1001, and the inner wall of the drive tube 23 is provided with two strip-shaped grooves 2301. The strip-shaped grooves 2301 are adapted to the strip-shaped protrusions 1001, and both are parallel to the central axis of the drive tube 23 and the riser 10.

[0059] When the V-shaped material feeding plate group reaches the end of its stroke, the drive motor 13 operates and drives the drive tube 23 to rotate through the first gear 14 and the second gear 15. Then, the drive tube 23 can drive the riser 10 to rotate through the strip groove 2301 and the strip protrusion 1001. In turn, the riser 10 can drive the discharge head 4 to perform a deflection action through the bend 9, so that the discharge head 4 changes position and ensures that during the movement of the discharge head 4 and the V-shaped material feeding plate group along the length direction of the frame 1, the discharge head 4 is always located on the side of the protrusion of the V-shaped material feeding plate group.

[0060] In this regard, the power mechanism is designed to switch the position of the discharge head 4 without affecting the lifting and lowering of the discharge head 4 and the V-shaped material-pulling plate assembly. In addition, during the position switching process of the discharge head 4, the bend 9 can trigger the driven mechanism, thereby causing the two assembly plates 6 to swing synchronously but in opposite directions. This ensures that, regardless of which side the discharge head 4 and the V-shaped material-pulling plate assembly move on the mold, the protruding part of the V-shaped material-pulling plate assembly always faces the direction of movement, and the discharge head 4 is always located on one side of the protruding part of the V-shaped material-pulling plate assembly, so as to properly utilize the "V" shape design of the V-shaped material-pulling plate assembly to achieve the pushing effect on the concrete.

[0061] Please refer to it again. Figure 7 , Figure 8 as well as Figure 10The driven mechanism includes a sliding engagement assembly mounted on the upright arm 5. This assembly is capable of relative movement with the upright arm 5 when the bent pipe 9 rotates. Each of the two mounting plates 6 is connected to the sliding engagement assembly via a transmission structure. The sliding engagement assembly includes two uprights 16 fixed to both sides of the upright arm 5, two sleeves 17 slidably mounted on the two uprights 16, and an arc-shaped member 18 fixedly connecting the two sleeves 17. The arc-shaped member 18 is concentric with the upright pipe 10. The arc-shaped member 18 has a groove, and the bent pipe 9 has a driving column 901 that passes through the groove and is slidably connected to the arc-shaped member 18. The groove includes a first through groove 1801 and a second through groove 1802 connected to each other. The first through groove 1801 is spirally arranged, and the second through groove 1802 is arc-shaped.

[0062] The transmission structure includes a guide rail 20 fixed to the side of the upright arm 5, a slider 21 slidably disposed on the guide rail 20, and a connecting rod 19 disposed between the slider 21 and the sleeve 17. The two ends of the connecting rod 19 are respectively hinged to the sleeve 17 and the slider 21. The assembly plate 6 is provided with a driven plate 8, the side of the slider 21 is provided with a follower elbow 22, the driven plate 8 is provided with a groove 801 adapted to the follower elbow 22, and the end of the follower elbow 22 away from the slider 21 extends into the groove 801 and is slidably connected to the driven plate 8.

[0063] With attachment Figure 8 Taking the shown state as an example, when the discharge head 4 changes position, the bent pipe 9 rotates, driving the drive column 901 to pass through the first through groove 1801 and the second through groove 1802 in sequence. When the drive column 901 passes through the first through groove 1801, it slides with the arc-shaped component 18. The column 16 and the sleeve 17 guide the arc-shaped component 18, causing the arc-shaped component 18 to move downwards. As a result, the sleeve 17 slides downwards relative to the column 16, and through the connecting rod 1... 9. Pushing the slider 21 to slide on the guide rail 20, the follower elbow 22 moves together with the slider 21, and the follower elbow 22 slides with the driven plate 8 through the slide groove 801, so that the driven plate 8 drives the assembly plate 6 to swing. As a result, the protrusion of the V-shaped material feeding plate group changes its orientation, ensuring that the protrusion of the V-shaped material feeding plate group always faces the direction of movement, and the discharge head 4 is always located on one side of the protrusion of the V-shaped material feeding plate group.

[0064] As another embodiment of the present invention, a molding method for energy-saving precast concrete components in roadbed protection and drainage engineering is also proposed, which uses the above-mentioned material placement device and includes the following steps:

[0065] Step 1: Clean the molding molds for energy-saving building materials;

[0066] Step 2: Material placement. The discharge head 4 and the V-shaped material-pushing plate assembly move back and forth on the mold. After reaching the end point of the movement, the power mechanism drives the discharge head 4 to change its position. The driven mechanism is triggered, causing the two assembly plates 6 to swing synchronously but in different directions. This ensures that the protruding part of the V-shaped material-pushing plate assembly always faces the direction of movement, and that the discharge head 4 is always located on one side of the protruding part of the V-shaped material-pushing plate assembly. When the V-shaped material-pushing plate assembly moves on the upper part of the mold, it pushes the concrete into the deep grooves on both sides of the mold, and the vibrator 7 vibrates the concrete.

[0067] Step 3: After the concrete in the deep grooves on both sides of the mold is filled, the vertical arm 5 rises intermittently to fill the space between the two deep grooves with concrete as a connection.

[0068] Step four: Install the cover plate on top of the mold. After the concrete has formed, disassemble the mold to obtain a U-shaped energy-saving building material.

5. A method for forming energy-saving precast concrete components for roadbed protection and drainage engineering, employing the material placement device as described in claim 1, characterized in that... Includes the following steps: Step 1: Clean the molding molds for energy-saving building materials; Step 2: The material is laid out, and the discharge head and V-shaped material-pushing plate assembly move back and forth on the mold. After reaching the end point of the movement, the power mechanism drives the discharge head to change its position. The driven mechanism is triggered, causing the two assembly plates to swing synchronously but in opposite directions. This ensures that the protruding part of the V-shaped material-pushing plate assembly always faces the direction of movement, and that the discharge head is always located on one side of the protruding part of the V-shaped material-pushing plate assembly. When the V-shaped material-pushing plate assembly moves on the upper part of the mold, it pushes the concrete into the deep grooves on both sides of the mold, and the vibrator compacts the concrete. Step 3: After the concrete in the deep grooves on both sides of the mold is filled, the vertical arm rises intermittently to fill the space between the two deep grooves with concrete as a connection. Step four: Install the cover plate on top of the mold. After the concrete has formed, disassemble the mold to obtain a U-shaped energy-saving building material.
