Description

Technical Field

[0001] This invention relates to the technical field of concrete pouring and molding, specifically to concrete grouting equipment based on embedded energy-saving sleeper beams and its grouting splicing method. Background Technology

[0002] As a key lateral force transmission component in highway bridge engineering, the sleeper beam is mainly used to support the load of the superstructure and transfer it to the bearing. Its performance directly affects the load-bearing capacity and service life of the highway bridge. With the deepening of the concept of green manufacturing, energy-saving sleeper beams have emerged. By incorporating large-particle-size energy-saving materials such as recycled coarse aggregate, waste concrete crushed aggregate, and lightweight aggregate into the concrete to replace natural crushed stone, not only is the energy consumption of ore mining and cement consumption significantly reduced, but the resource utilization of construction solid waste is also effectively realized, and carbon emissions and environmental pollution in the production process are significantly reduced.

[0003] However, existing grouting equipment typically employs a direct pouring process, where concrete is injected into the mold in one go and then vibrated. During this process, the concrete is in a fluid state after entering the mold. Due to the low viscosity of the grout, large-diameter aggregates continue to settle under gravity, causing internal aggregates to squeeze and interlock, making full dispersion difficult. When vibration is introduced, the aggregates often have already settled to the bottom, forming an initial skeletal structure, resulting in "large aggregate clusters" in the middle or lower part of the bolster beam, while the top of the mold exhibits a segregated state of grout enrichment and aggregate scarcity. This uncontrollable interlayer separation leads to severely uneven aggregate distribution within the mold, with excessive aggregate enrichment in the bottom area and insufficient strength in the top area. Ultimately, this results in the mechanical properties and durability of the formed bolster beam failing to meet design standards, hindering the performance and engineering application of energy-saving materials. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete grouting device and a grouting splicing method based on an embedded energy-saving sleeper beam, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The concrete grouting equipment based on embedded energy-saving bolster beams includes a frame and also includes:

[0007] The material trough and the baffle that are slidably connected to the material trough are provided on the frame. The material trough and the baffle are provided with multiple first openings and second openings at equal intervals along their own width direction.

[0008] An assembly plate is mounted on the frame and can reciprocate along the length of the frame. A guide arm is provided at the bottom of the assembly plate. A telescopic arm is slidably fitted onto the guide arm. Two push plates are rotatably connected to the bottom of the telescopic arm through a pivot pin.

[0009] When the assembly plate moves to one side, the concrete delivery port on the side of the assembly plate moving in the direction of movement pumps concrete toward the center of the material trough. The two pusher plates are in a "V" shape, and the first and second openings do not completely overlap, so that the slurry is poured into the mold located below the material trough. Large aggregates are intercepted. Before the assembly plate moves to the other side, the power mechanism on the assembly plate can drive the two pusher plates to rise and be pulled out of the material trough. The follower mechanism located between the guide arm and the telescopic arm is triggered, causing the two pusher plates to swing and switch to a "I" shape. The baffle is driven by the power mechanism to move along the width direction of the material trough, so that the first and second openings completely overlap, so that large aggregates can be poured into the mold.

[0010] Among them, after the two pusher plates switch to the "I" shape, the auxiliary material discharge mechanism set on the pusher plates passes through the first opening and the second opening;

[0011] After the assembly plate completes multiple reciprocating movements, a multi-layered, staggered distribution structure of slurry and large aggregate is formed inside the mold. The multi-layered, staggered distribution structure is then compacted and vibrated using a compaction device and a vibration device.

[0012] The concrete grouting equipment based on embedded energy-saving bolster beams as described above: the power mechanism includes a first lead screw rotatably mounted on the assembly plate and a first threaded sleeve threadedly connected to the first lead screw and fixed to the telescopic arm. A servo motor is also mounted on the assembly plate. The output end of the servo motor is connected to the first lead screw. The first lead screw is also connected to the baffle through a transmission mechanism.

[0013] The concrete grouting equipment based on embedded energy-saving bolster beams as described above: the transmission mechanism includes a second lead screw rotatably mounted on the assembly plate and a second threaded sleeve threadedly connected to the second lead screw. The second lead screw is connected to the first lead screw through a bevel gear set. A transverse guide rail is connected to the side of the baffle. A slider is slidably fitted inside the transverse guide rail. The second threaded sleeve is connected to the slider through a connecting arm.

[0014] As described above, the concrete grouting equipment based on embedded energy-saving bolster beam has a support arm fixedly provided on the side of the telescopic arm, and the follow-up mechanism includes a movable seat slidably sleeved on the support arm, and a sliding fit structure is provided between the movable seat and the guide arm.

[0015] The movable seat has a protruding post on each side, and the pusher plate has a protrusion on its side. The protruding post passes through a groove on the protrusion and is slidably connected to the protrusion.

[0016] The concrete grouting equipment based on embedded energy-saving bolster beam as described above: the sliding fit structure includes a driven plate disposed on the movable seat and a protruding block disposed on the side of the guide arm. A column is disposed on the side of the protruding block facing the driven plate, and a groove adapted to the column is provided on the driven plate. The column passes through the groove.

[0017] The trough includes a vertical trough and an inclined trough connected together. When the telescopic arm drives the two pusher plates to rise, the inclined trough passes the column, and the column can cause the driven plate to drive the movable seat to move toward the telescopic arm.

[0018] As described above, the concrete grouting equipment based on embedded energy-saving bolster beams includes an auxiliary material discharge mechanism comprising a connecting plate located above the pusher plate. The connecting plate is connected to an elastic support structure located on the side of the telescopic arm, and multiple movable arm assemblies are equidistantly arranged on the connecting plate. The movable arm assemblies can pass through the first opening and the second opening.

[0019] The concrete grouting equipment based on the embedded energy-saving bolster beam described above: the movable arm assembly includes a follower arm fixed to the connecting plate and a swing arm slidably connected to the pusher plate, wherein the follower arm and the swing arm are rotatably connected by an elastic hinge.

[0020] A cylinder is also installed on the assembly plate. The movable end of the cylinder is provided with a pressure-applying component. When the movable end of the cylinder extends, it can apply pressure to the connecting plate through the pressure-applying component, so that the follower arm and the swing arm move down. When the swing arm passes through the pusher plate, it performs a swaying action.

[0021] The concrete grouting equipment based on embedded energy-saving bolster beams as described above: the elastic support structure includes a column fixed to the telescopic arm by an assembly block, a columnar spring sleeved on the outer periphery of the column, and a connecting block slidably connected to the column. The two ends of the columnar spring are respectively connected to the assembly block and the connecting block.

[0022] The connecting block and the connecting plate are provided with a first arc-shaped arm and a second arc-shaped arm, which are slidably fitted together and are concentric with the shaft pin.

[0023] The concrete grouting splicing method based on embedded energy-saving sleeper beams, using the aforementioned concrete grouting equipment based on embedded energy-saving sleeper beams, includes the following steps:

[0024] Step 1: Mark out the position using the seam between the new and old boards as the boundary, and install the mold;

[0025] Step two: The two pusher plates move in a "V" shape to one side, pushing the concrete raw materials in the material trough to both sides. The first and second openings are not completely connected. The slurry is poured into the mold, and the large aggregates are intercepted.

[0026] Step 3: The power mechanism drives the two pusher plates to rise, and the two pusher plates switch to a straight line shape. The first and second ports are fully connected, and the auxiliary discharge mechanism passes through the first and second ports and moves to the other side along with the two pusher plates.

[0027] Step four, repeat steps two and three 6-8 times;

[0028] Step 5: Compact and vibrate the raw material inside the mold using a compaction device and a vibration device;

[0029] Step six: Shape the pillow beam and remove the mold.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] This invention features two pusher plates that can form a "V" shape and a "I" shape during the reciprocating motion of the assembly plate. When in the "V" shape, the two pusher plates can push the concrete material in the trough to both sides, achieving uniform material distribution. Since the first and second openings are not fully connected at this time, slurry can be poured into the mold, while large aggregates are intercepted. When the two pusher plates switch to the "I" shape, the baffle slides in the width direction of the trough, causing the first and second openings to completely overlap, thereby releasing the intercepted large aggregates and pouring them into the mold.

[0032] After repeated cycles, a multi-layered, interwoven structure of slurry and large aggregates is formed inside the mold. Then, a compaction and vibration device is used to compact and vibrate the multi-layered, interwoven structure, transforming it into uniform penetration in the vertical direction. Compared with the one-time injection method, this effectively avoids the large aggregates squeezing and biting against each other, making it difficult to achieve sufficient dispersion. This ultimately leads to the phenomenon of "large aggregate clusters" in the middle or lower part of the pillow beam, resulting in a segregated state of slurry enrichment and aggregate depletion at the top of the mold. This makes it difficult for the mechanical properties and durability of the formed pillow beam to meet the design standards, restricting the performance and engineering application of energy-saving materials.

Detailed Implementation

[0044] 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.

[0045] Furthermore, elements in this invention are referred to as being "disposed on" or "located 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 implementation.

[0046] Please see Figures 1-10 In this embodiment, the concrete grouting equipment based on the embedded energy-saving bolster beam includes a frame 1, and further includes:

[0047] The material trough 4 and the baffle 6 slidably connected to the material trough 4 are provided on the frame 1. The material trough 4 and the baffle 6 are respectively provided with multiple first openings 401 and second openings 601 at equal intervals along their own width direction.

[0048] An assembly plate 2 is mounted on the frame 1 and can reciprocate along the length of the frame 1. A guide arm 9 is provided at the bottom of the assembly plate 2. A telescopic arm 10 is slidably fitted onto the guide arm 9. Two push plates 11 are rotatably connected to the bottom end of the telescopic arm 10 through a shaft pin 8.

[0049] When the assembly plate 2 moves to one side, the concrete delivery port on the side of the assembly plate 2 moving in the direction of movement pumps concrete toward the center of the material trough 4. The two pusher plates 11 are in a "V" shape. The first opening 401 and the second opening 601 do not completely overlap, so that the slurry is poured into the mold 5 located below the material trough 4. The large aggregate is intercepted. Before the assembly plate 2 moves to the other side, the power mechanism on the assembly plate 2 can drive the two pusher plates 11 to rise and be pulled out of the material trough 4. The follower mechanism between the guide arm 9 and the telescopic arm 10 is triggered, driving the two pusher plates 11 to swing and switch to a "I" shape. The baffle 6 is driven by the power mechanism to move along the width direction of the material trough 4, so that the first opening 401 and the second opening 601 completely overlap, so that the large aggregate can be poured into the mold 5.

[0050] Among them, after the two pusher plates 11 are switched to the "I" shape, the auxiliary material discharge mechanism set on the pusher plate 11 passes through the first opening 401 and the second opening 601.

[0051] After the assembly plate 2 completes multiple reciprocating movements, a multi-layered staggered distribution structure of slurry and large aggregate is formed inside the mold 5. The multi-layered staggered distribution structure is compacted and vibrated using a compaction device and a vibration device.

[0052] In this embodiment, it should be further explained that linear drive modules 3 are installed on both sides of the frame 1, and the assembly plate 2 is connected to the two linear drive modules 3. The linear drive modules 3 are based on screw drive to realize the reciprocating movement of the assembly plate 2 in the length direction of the frame 1 during the operation.

[0053] In practical operation, the concrete conveying port is installed on the side of the assembly plate 2. When the two pusher plates 11 are in a "V" shape and the first opening 401 and the second opening 601 are not completely overlapped, the assembly plate 2 moves, and the concrete conveying port is located in front of the assembly plate 2, moving together with the assembly plate 2. The concrete conveying port is located above the middle of the material trough 4. Therefore, the two pusher plates 11 in the "V" shape can push the concrete material in the middle of the material trough 4 to both sides in the width direction of the material trough 4, so that the concrete material can be evenly spread. The first opening 401 and the second opening 601 do not completely overlap, so the slurry can pass through and be poured into the mold 5, while the large aggregate cannot pass through and is blocked. After the assembly plate 2 reaches the end of the stroke, the power mechanism drives the two pusher plates 11 to rise and be pulled out from the material trough 4. The follower mechanism drives the two pusher plates 11 to swing synchronously but in different directions, switching to the "I" shape. The baffle 6 is driven by the power mechanism to move along the width direction of the material trough 4, so that the first opening 401 and the second opening 601 completely overlap, so that the large aggregate can be poured into the mold 5.

[0054] The auxiliary discharge mechanism can pass through the first opening 401 and the second opening 601, and thus, during its movement along the first opening 401 and the second opening 601, it can promote the discharge of the mud remaining in the first opening 401 and the second opening 601.

[0055] As a further embodiment of the present invention, please refer again. Figure 6 and Figure 8 The power mechanism includes a first lead screw 27 rotatably mounted on the assembly plate 2 and a first threaded sleeve 28 threadedly connected to the first lead screw 27 and fixed to the telescopic arm 10. A servo motor 26 is also mounted on the assembly plate 2. The output end of the servo motor 26 is connected to the first lead screw 27. The first lead screw 27 is also connected to the baffle 6 through a transmission mechanism.

[0056] The transmission mechanism includes a second lead screw 29 rotatably mounted on the assembly plate 2 and a second threaded sleeve 30 threadedly connected to the second lead screw 29. The second lead screw 29 is connected to the first lead screw 27 through a bevel gear set 31. A transverse guide rail 7 is connected to the side of the baffle 6. A slider 33 is slidably fitted inside the transverse guide rail 7. The second threaded sleeve 30 is connected to the slider 33 through a connecting arm 32.

[0057] In detail, the bevel gear set 31 includes a first bevel gear fixedly mounted on the first lead screw 27 and a second bevel gear fixedly mounted on the end of the second lead screw 29 facing the first lead screw 27, and the second bevel gear meshes with the first bevel gear;

[0058] When the assembly plate 2 reciprocates along the length of the frame 1, the second threaded sleeve 30 drives the slider 33 to slide on the transverse guide rail 7 through the connecting arm 32;

[0059] When the servo motor 26 drives the first lead screw 27 to rotate, the first threaded sleeve 28 engages with the first lead screw 27 to drive the telescopic arm 10 to slide up or down on the guide arm 9, thereby adjusting the height of the two push plates 11. At the same time, the first lead screw 27 drives the second lead screw 29 to rotate through the bevel gear set 31. The second threaded sleeve 30 engages with the second lead screw 29, which can drive the transverse guide rail 7 to slide the baffle 6 along the width direction of the material groove 4 through the connecting arm 32 and the slider 33, so that the first port 401 and the second port 601 are fully or partially connected.

[0060] As a further embodiment of the present invention, please refer again. Figure 5 and Figure 9 The telescopic arm 10 has a support arm 1001 fixedly mounted on its side. The follower mechanism includes a movable seat 13 slidably mounted on the support arm 1001. The movable seat 13 and the guide arm 9 are provided with a sliding fit structure. The movable seat 13 has a protruding post 1301 connected to each side. The pusher plate 11 has a protruding part 14 on its side. The protruding post 1301 passes through a sliding groove 1401 on the protruding part 14 and is slidably connected to the protruding part 14.

[0061] The sliding fit structure includes a driven plate 15 disposed on the movable seat 13 and a protruding block 12 disposed on the side of the guide arm 9. A column 1201 is disposed on the side of the protruding block 12 facing the driven plate 15, and the driven plate 15 is provided with a groove adapted to the column 1201. The column 1201 passes through the groove. The groove includes a vertical groove 1501 and an inclined groove 1502 connected together. When the telescopic arm 10 drives the two pusher plates 11 to rise, when the inclined groove 1502 passes the column 1201, the column 1201 can cause the driven plate 15 to drive the movable seat 13 to move toward the telescopic arm 10.

[0062] In this embodiment, the first threaded sleeve 28 drives the telescopic arm 10 to slide upward on the guide arm 9, so that during the process of the two pusher plates 11 being raised, the vertical groove 1501 and the inclined groove 1502 pass through the column 1201 in sequence. It should be noted that before the inclined groove 1502 reaches the height of the column 1201, the two pusher plates 11 have been pulled out from the material groove 4. Subsequently, when the inclined groove 1502 passes through the column 1201, the column 1201 slides with the driven plate 15, so that the driven plate 15 drives the movable seat 13 to slide towards the telescopic arm 10 on the support arm 1001. Correspondingly, the protruding column 1301 slides with the protruding part 14 through the sliding groove 1401, thereby causing the pusher plates 11 to swing until the two pusher plates 11 form a "I" shape, so that the subsequent auxiliary material discharge mechanism can pass through the first opening 401 and the second opening 601.

[0063] This invention employs two pusher plates 11, which can form "V" and "I" shapes during the reciprocating movement of the assembly plate 2. When in the "V" shape, the two pusher plates 11 can push the concrete material in the trough 4 to both sides, achieving uniform material distribution. Since the first opening 401 and the second opening 601 are not fully connected at this time, slurry can be poured into the mold 5, while large aggregates are intercepted. When the two pusher plates 11 switch to the "I" shape, the baffle 6 slides in the width direction of the trough 4, causing the first opening 401 and the second opening 601 to completely overlap, thereby releasing the intercepted large aggregates and allowing them to be poured into the mold 5. In mold 5, after multiple cycles, a multi-layered, interwoven structure of slurry and large aggregates is formed. Then, a compaction and vibration device is used to compact and vibrate the multi-layered, interwoven structure, transforming it into uniform penetration in the vertical direction. Compared with the one-time injection method, this can effectively avoid the large aggregates squeezing and biting each other, making it difficult to achieve sufficient dispersion. This ultimately leads to the phenomenon of "large aggregate clusters" in the middle or lower part of the pillow beam, resulting in a segregated state of slurry enrichment and aggregate depletion at the top of mold 5. This makes it difficult for the mechanical properties and durability of the formed pillow beam to meet the design standards, restricting the performance and engineering application of energy-saving materials.

[0064] As a further embodiment of the present invention, please refer again. Figure 5 , Figure 8 as well as Figure 9 The auxiliary material discharge mechanism includes a connecting plate 23 disposed above the pusher plate 11. The connecting plate 23 is connected to an elastic support structure disposed on the side of the telescopic arm 10. Multiple movable arm assemblies are equidistantly arranged on the connecting plate 23, and each movable arm assembly can pass through the first opening 401 and the second opening 601. Each movable arm assembly includes a follower arm 24 fixed to the connecting plate 23 and a swing arm 25 slidably connected to the pusher plate 11. The follower arm 24 and the swing arm 25 are rotatably connected by an elastic hinge.

[0065] A cylinder 20 is also installed on the assembly plate 2. The movable end of the cylinder 20 is provided with a pressure member 2001. When the movable end of the cylinder 20 extends, it can apply pressure to the connecting plate 23 through the pressure member 2001, so that the follower arm 24 and the swing arm 25 move down. When the swing arm 25 passes through the pusher plate 11, it performs a swaying action.

[0066] Furthermore, regarding the elastic hinge between the follower arm 24 and the swing arm 25, a cylindrical cavity is set at the axis of rotation of the two, and a torsion spring is coaxially sleeved on the shaft. One end of the torsion spring is fixed to the shaft (rotates with the swing arm 25), and the other end is fixed to the inner wall of the cavity (remains stationary with the follower arm 24).

[0067] Please see the appendix Figure 10 In the left part of the figure, the two pusher plates 11 are in the shape of "V". During the process, they move to the right to achieve the function of uniform material distribution.

[0068] In the right part of the figure, the two pusher plates 11 are in the shape of "I". The moving end of the cylinder 20 presses down on the connecting plate 23 through the pressure member 2001, so that the swing arm 25 passes through the pusher plate 11 and rebounds through the internal torsion spring, so that the swing arm 25 is in an inclined state. During operation, the pusher plate 11 moves to the left and the swing arm 25 is located in the first port 401 and the second port 601. The inclined swing arm 25 can effectively scrape off the mud remaining in the first port 401 and the second port 601, effectively preventing mud residue from affecting the normal operation of the next round of work.

[0069] As a further embodiment of the present invention, the elastic support structure includes a column 17 fixed to the telescopic arm 10 by an assembly block 16, a columnar spring 18 sleeved on the outer periphery of the column 17, and a connecting block 19 slidably connected to the column 17. The two ends of the columnar spring 18 are respectively connected to the assembly block 16 and the connecting block 19.

[0070] The connecting block 19 and the connecting plate 23 are provided with a first arc-shaped arm 21 and a second arc-shaped arm 22, which are slidably fitted together and are concentric with the shaft pin 8.

[0071] In this embodiment, when the pusher plate 11 swings, the first arc arm 21 and the second arc arm 22 slide relative to each other. When the cylinder 20 does not apply pressure to the connecting plate 23 through the pressure application component 2001, under the elastic support of the column spring 18, the swing arm 25 is located inside the pusher plate 11 and is flush with the bottom of the swing arm 25.

[0072] It should be noted that the total number of swing arms 25 on the two push plates 11 is the same as the number of first openings 401 in the material trough 4. After the two push plates 11 switch from a “V” shape to a “I” shape, the multiple swing arms 25 correspond to the multiple first openings 401 respectively. When the cylinder 20 applies pressure to the connecting plate 23 downward through the pressure application component 2001, the connecting block 19 slides towards the assembly block 16 on the column 17, the column spring 18 is compressed, and the connecting plate 23 pushes the follower arm 24 and the swing arm 25 downward until the swing arm 25 completely passes through the push plate 11. Thus, the swing arm 25 can swing due to the rebound of the torsion spring. In subsequent work, the swing arm 25 remains in an inclined state and moves within the first opening 401 and the second opening 601 to remove residual mud.

[0073] After the movable end of the cylinder 20 retracts, the cylindrical spring 18 rebounds to drive the components to reset. Compared with the torsion spring between the follower arm 24 and the swing arm 25, the cylindrical spring 18 has a larger elastic potential energy, so as to ensure that when the cylindrical spring 18 rebounds, it can cause the connecting plate 23 to pull the swing arm 25 back to the push plate 11 through the follower arm 24.

[0074] The concrete grouting splicing method based on embedded energy-saving sleeper beams, using the aforementioned concrete grouting equipment based on embedded energy-saving sleeper beams, includes the following steps:

[0075] Step 1: Mark out the position using the seam between the new and old boards as the boundary, and install mold 5;

[0076] Step 2: The two pusher plates 11 move to one side in a "V" shape, pushing the concrete raw materials in the material trough 4 to both sides. The first opening 401 and the second opening 601 are not completely connected. The slurry is poured into the mold 5, and the large aggregate is intercepted.

[0077] Step 3: The power mechanism drives the two pusher plates 11 to rise, and the two pusher plates 11 switch to the "I" shape. The first port 401 and the second port 601 are fully connected. The auxiliary discharge mechanism passes through the first port 401 and the second port 601 and moves to the other side along with the two pusher plates 11.

[0078] Step four, repeat steps two and three 6-8 times;

[0079] Step 5: Compact and vibrate the raw material in mold 5 using a compaction device and a vibration device;

[0080] Step 6: Pillow beam forming, mold 5 removed.

[0081] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
