Description

Technical Field

[0001] This invention relates to the field of concrete processing equipment technology, specifically to a high-density concrete pavement slab vibration compaction processing equipment and processing method. Background Technology

[0002] In airport prefabricated concrete pavement systems, the precision and strength of precast slabs require careful control. While high-precision steel formwork can control slab precision, improving slab strength and durability requires further investigation. During factory prefabrication, after the concrete slurry enters the mold, it needs to be vibrated using a vibrating table or vibrator to remove air bubbles and ensure density. However, existing vibrating tables are unsuitable for assembly line operations, and it's difficult to use vibrators in conjunction with them for compaction. Manual compaction is labor-intensive and ineffective. Furthermore, existing equipment lacks monitoring facilities for slurry vibration or vibration quality. To obtain pavement slabs with higher density, improvements to existing technologies are necessary. Summary of the Invention

[0003] This invention provides a vibratory compaction equipment and method for high-density concrete pavement slabs, with the aim of further improving the compactness of the pavement slabs.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A high-density concrete pavement slab vibration compaction processing device includes: a controller, a vibration table, a compaction mechanism, a conveyor track, and a pre-vibrating slurry mold trolley. The pre-vibrating slurry mold trolley moves along the conveyor track. A vibration table is located inside the conveyor track, and a compaction mechanism is located above the vibration table. The pre-vibrating slurry mold trolley has a pavement slab mold groove, and pre-vibration units are located on both sides of the mold groove. The pre-vibration units cause the pre-vibrating slurry mold trolley to vibrate the slurry in the mold groove at high frequency as it moves along the conveyor track. The pre-vibration mechanism includes a cover structure that seals and engages with the upper port of the mold groove, and is equipped with several vibrating rods. Each vibrating rod is equipped with a negative pressure guiding unit. The vibration table and the pre-vibration slurry mold trolley are positioned relative to each other through a positioning unit. The vibration mechanism also includes a monitoring unit for observing slurry vibration and / or vibration quality. The controller is electrically connected to a power source and is electrically connected to the traveling mechanism of the pre-vibration slurry mold trolley, the vibration table, the vibrating rods, the negative pressure guiding unit, the positioning unit, the pre-vibration unit, and the monitoring unit via wires.

[0006] Preferably, the assembly line track includes a track body and a track support platform located below the track body, and the assembly line track is used to connect the upstream and downstream processes of the prefabrication assembly line for the track panel.

[0007] Preferably, the pre-vibrating slurry mold trolley includes a base plate, with traveling mechanisms at both ends of the base plate, the traveling mechanisms being connected to the track body, a through groove in the middle of the base plate, a mold groove slidably connected longitudinally in the through groove, and first connecting plates fixedly connected to the top two sides of the mold groove, the pre-vibration unit including a plurality of first vibration springs disposed between the lower surface of the first connecting plate and the upper surface of the base plate, a first guide rod penetrating the base plate at the central axis of the first vibration spring, the top end of the first guide rod being fixedly connected to the lower surface of the first connecting plate, a limiting block at the bottom end of the first guide rod, a first vibration motor disposed at the top of the first connecting plate opposite to the first guide rod, and a controller electrically connected to the first vibration motor, wherein when the pre-vibrating slurry mold trolley moves away from the previous station towards the vibration table, the controller starts the first vibration motor to pre-vibrate the slurry in the mold groove.

[0008] Preferably, the vibration table includes a vibration plate, and second connecting plates are fixedly connected to the left and right ends of the vibration plate, respectively. The second connecting plates are arranged longitudinally upwards. The positioning unit includes a first cylinder and a through-beam photoelectric sensor. The first cylinder is embedded in the second connecting plate, and the telescopic end of the first cylinder extends in a direction perpendicular to the side wall of the mold groove. An extrusion block is also fixedly connected to the telescopic end of the first cylinder. A guide plate is provided at the lower part of the side wall of the mold groove. The upper surface of the guide plate is an inwardly upward inclined surface. The extrusion block cooperates with the inclined surface to extrude... While pressing and fixing the mold groove, the bottom end of the mold groove abuts against the upper surface of the vibrating plate. The edge of the upper surface of the vibrating plate is also rectangularly distributed with four transmitting ends of through-beam photoelectric sensors. Corresponding to the transmitting ends, the lower surface of the base plate is provided with receiving ends of through-beam photoelectric sensors. When the pre-vibrating slurry mold trolley and the vibrating table are positioned by through-beam photoelectric sensors, the pre-vibrating slurry mold trolley is simultaneously positioned with the vibration mechanism. The lower surface of the vibrating plate is provided with a second vibration motor. The left and right ends of the lower surface of the vibrating plate are respectively connected to the vibrating table fixing seat through a second vibration spring.

[0009] Preferably, support plates are provided on both sides of the assembly line track where the vibration table is located, and a third connecting plate is fixedly connected to the top of the two support plates. The third connecting plate is connected to the vibration mechanism through a driving mechanism.

[0010] Preferably, the vibration mechanism includes a fixed plate horizontally disposed below the third connecting plate, a first force-applying plate disposed above the third connecting plate, and a driving mechanism including a second cylinder longitudinally disposed at the center of the top of the third connecting plate. The fixed end of the second cylinder is fixedly connected to the upper surface of the third connecting plate, and the telescopic end is fixedly connected to the lower surface of the first force-applying plate. The four corners of the lower surface of the first force-applying plate are connected to the second force-applying plate via second guide rods that penetrate the third connecting plate and are slidably connected to it. The third cylinder is disposed at the center of the bottom end of the second force-applying plate, and the fixed end of the third cylinder is connected to the lower surface of the second force-applying plate. The surface is fixedly connected, and the telescopic end is fixedly connected to the upper surface of the fixed plate. The covering structure includes a surrounding plate that is sealed and fixedly connected to the bottom end of the second force-applying plate. The cross-sectional shape and size of the surrounding plate match the cross-section of the mold groove. The bottom end of the surrounding plate is provided with a sealing groove. When the surrounding plate moves downward under the drive of the second force-applying plate, the sealing groove seals and covers the top of the mold groove. The outer edge of the fixed plate is sealed and slidably connected to the inner surface of the surrounding plate through an elastic rubber ring. Several vibrating rods are arranged in a matrix on the lower surface of the fixed plate. The first cylinder, the second cylinder, the third cylinder, the transmitting end, the receiving end, and the vibrating rods are electrically connected to the controller through wires.

[0011] Preferably, the negative pressure guiding unit includes several vent holes formed around the vibrator on a fixed plate, a negative pressure pump, and a guiding component disposed on the surface of the vibrator body. The negative pressure pump is fixedly installed on the upper surface of the second force-applying plate, and the input end of the negative pressure pump is connected to a pre-set air outlet pipe on the side wall of the surrounding plate via a flexible connecting pipe. The vibrator body includes a first guiding section at the upper part and a second guiding section at the lower part. The second guiding section is used to guide the flow into the slurry, and the first guiding section is used to guide the gas overflowing from the slurry. The first guiding section includes several guiding grooves arranged longitudinally around the axis of the vibrator body on the outer surface of the first guiding section. The second guiding section includes multiple rows of protruding structures arranged longitudinally on the outer surface of the vibrator body. The protruding structure described is spherical or ellipsoidal. The lower part of the spherical or ellipsoidal structure is cut into a horizontal structure. The protruding structures in adjacent rows are arranged alternately. When the vibrator is quickly inserted into the slurry downwards, the horizontal structure squeezes the air bubbles in the slurry, causing the air bubbles to move upwards along the spherical or ellipsoidal surface and overflow upwards along the gaps in the protruding structure. When the vibrator is slowly pulled upwards, the horizontal structure creates a negative pressure in the slurry by lifting, attracting the gas in the surrounding slurry into the space around the second guide section. This process of repeatedly lifting and pulling the vibrator attracts and guides the gas in the slurry while vibrating. The gas output along the second guide section moves upwards along the guide groove under the negative pressure attraction at several vent holes, passes through the vent holes, enters the negative pressure pump, and is discharged.

[0012] Preferably, the fixing plate is slidably connected to the second force-applying plate via a third guide rod that passes through the second force-applying plate, and a sealing guide cylinder is also fixedly connected to the upper end of the second force-applying plate, with the third guide rod slidably connected to the sealing guide cylinder.

[0013] Preferably, the monitoring unit includes a vision sensor spaced between the vibrating rods in adjacent rows. The vision sensor is connected to the controller via a wire. When the controller determines that the vibration and / or compaction has reached the preset standard according to the preset program, the first cylinder releases the fixation of the mold slot, and the pre-vibrating slurry mold trolley carries the vibrated and / or compacted slurry along the production line track to the next station.

[0014] A processing method for high-density concrete pavement slabs using vibratory compaction equipment includes the following steps:

[0015] Step S1: As the pre-vibrating slurry mold trolley moves away from the previous station and toward the vibrating table, the controller starts the first vibration motor to pre-vibrate the slurry in the mold groove.

[0016] Step S2: When the pre-vibration slurry mold trolley moves above the vibration table and triggers the through-beam photoelectric sensor, the first cylinder actuates to fix the mold slot.

[0017] Step S3: The second cylinder is activated, the surrounding plate and the mold groove cover are combined to form a sealing structure, and the vibrating rod is inserted into the slurry in the mold groove.

[0018] Step S4: The controller starts the third cylinder to insert the vibrating rod into the slurry to the set depth and starts the pre-vibration quality detection. During the pre-vibration quality detection, the vibrating rod is started to vibrate. If the floating slurry or air bubbles on the surface of the slurry do not decrease to a certain extent after a certain period of vibration, it means that the pre-vibration has compacted the slurry. Then the first cylinder is released, and the pre-vibration slurry mold trolley moves to the next station.

[0019] Step S5: When the pre-vibration quality test fails to meet the standard, start the vibration table and negative pressure pump, and combine the high-frequency vibration of the vibration table with the vibration of the vibrating rod.

[0020] Step S6: When the floating slurry or bubbles on the slurry surface detected by the vision sensor are reduced to the set level, it means that the slurry processing is completed. The controller releases the first cylinder, causing the pre-vibration slurry mold trolley to move to the next station and take over the slurry processing of the next pre-vibration slurry mold trolley.

[0021] The beneficial effects of the high-density concrete pavement slab vibration compaction equipment and processing method of the present invention are as follows:

[0022] This invention is fully adaptable to assembly line operations and can realize automated slurry processing. At the same time, the vibration table of this invention can work in conjunction with the compaction mechanism. By setting a negative pressure flow guiding unit, it achieves precise directional flow guidance, which improves the efficiency and quality of slurry processing. In addition, this invention also has a monitoring unit for monitoring the quality of slurry compaction or vibration. While ensuring the quality of slurry processing, it avoids the subjective influence of human judgment, thereby enabling the production of prefabricated paving panels with higher density in the factory.

[0037] The following description provides a detailed explanation of the embodiments of the present invention in a step-by-step manner. This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

They are only for describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limiting this invention.

[0039] Example 1:

[0040] A vibratory compaction equipment for high-density concrete pavement slabs, such as Figure 1 , 2As shown, it includes: a controller (not shown in the figure), a vibrating table, a tamping mechanism, a production line track, and a pre-vibrating slurry mold trolley. The pre-vibrating slurry mold trolley moves along the production line track. A vibrating table is provided on the inner side of the production line track, and a tamping mechanism is provided above the vibrating table. The pre-vibrating slurry mold trolley is provided with a track panel mold groove 3. Pre-vibration units are provided on both sides of the mold groove 3. The pre-vibration units enable the pre-vibrating slurry mold trolley to perform high-frequency pre-vibration on the slurry in the mold groove as it moves along the production line track. When the production line is too long or there is a queue, the pre-vibration units can make full use of the time to vibrate the slurry in advance, thereby effectively improving the efficiency of slurry processing.

[0041] The vibrating mechanism is equipped with a cover structure that seals and engages with the upper port of the mold groove, and is equipped with several vibrating rods. The vibrating rods are equipped with a negative pressure guiding unit. The cover structure is used in conjunction with the negative pressure guiding unit to prevent outside air from entering during the negative pressure guiding process. The vibrating table and the pre-vibrating slurry mold trolley are positioned to each other through a positioning unit. Only with precise positioning can the vibrating table and vibrating rods achieve the best effect.

[0042] The vibration mechanism also includes a monitoring unit for observing the vibration and / or vibration quality of the slurry. The controller is electrically connected to a power source and, via wires, to the traveling mechanism of the pre-vibrating slurry mold trolley, the vibration table, the vibrating rod, the negative pressure guiding unit, the positioning unit, the pre-vibration unit, and the monitoring unit. The monitoring unit precisely controls the processing quality of the slurry, avoiding subjective errors caused by manual observation. Through these features, the present invention enables automated processing of concrete slurry, achieving assembly line operation functionality.

[0043] Example 2

[0044] Based on Example 1, this example further discloses:

[0045] like Figure 1 , 2 As shown in Figure 3, the assembly line track includes a track body 0003 and a track support platform 0002 located below the track body 0003. The assembly line track is used to connect the upstream and downstream processes of the prefabrication assembly line for the track panel.

[0046] like Figure 1 , 2As shown in Figures 3 and 5, the pre-vibration slurry mold trolley includes a base plate 1. A traveling mechanism 2 is provided at both ends of the base plate 1, and the traveling mechanism 2 is connected to the track body 0003. A through groove (not marked in the figure) is provided in the middle of the base plate 1. A mold groove 3 is slidably connected longitudinally within the through groove. First connecting plates 4 are fixedly connected to the top two sides of the mold groove 3. The pre-vibration unit includes several first vibration springs located between the lower surface of the first connecting plate and the upper surface of the base plate. A first guide rod 7 penetrating the base plate 1 is provided at the central axis of each first vibration spring 5. The top end of the first guide rod 7 is fixedly connected to the lower surface of the first connecting plate 4. A limiting block (not marked in the figure, serving as an anti-detachment function) is provided at the bottom end of the first guide rod 7. A first vibration motor 6 is provided at the top of the first connecting plate 4 opposite to the first guide rod 7. The controller is electrically connected to the first vibration motor 6. When the pre-vibration slurry mold trolley moves away from the previous workstation towards the vibration table, the controller starts the first vibration motor 6 to pre-vibrate the slurry in the mold groove.

[0047] Since the vibration processing time of slurry is relatively short, the present invention is equipped with a pre-vibrating slurry mold trolley that can be pre-vibrated. The pre-vibrating slurry mold trolley itself constitutes a mechanism that vibrates while moving, which can significantly improve the processing efficiency for large-scale paving panel processing. When it reaches the vibrating table side, if the pre-vibration does not meet the standard, it only needs to pass through the vibrating table and vibrating rod for a short time to process.

[0048] Example 3

[0049] Based on Example 2, this example further discloses:

[0050] like Figure 1 , 2As shown in Figures 6 and 8, the vibration table includes a vibration plate 03. A second connecting plate 03-1 is fixedly connected to the left and right ends of the vibration plate 03, respectively. The second connecting plate 03-1 is arranged longitudinally upwards. The positioning unit includes a first cylinder 03-2 and a through-beam photoelectric sensor. The first cylinder 03-2 is embedded in the second connecting plate 03-1. The telescopic end of the first cylinder extends in a direction perpendicular to the side wall of the mold groove 3. An extrusion block 03-3 is also fixedly connected to the telescopic end of the first cylinder. A guide plate 8 is provided at the lower part of the side wall of the mold groove 3. The upper surface of the guide plate 8 is an inwardly upward inclined surface. The extrusion block matches the inclined surface. When the mold groove 3 is pressed and fixed, the bottom end of the mold groove 3 abuts against the upper surface of the vibrating plate 03. The upper edge of the vibrating plate is also rectangularly distributed with four transmitting ends 03-4 of the through-beam photoelectric sensor. Corresponding to the transmitting end, the lower surface of the base plate 1 is provided with the receiving end of the through-beam photoelectric sensor (not shown in the figure). When the pre-vibrating slurry mold trolley and the vibrating table are positioned by the through-beam photoelectric sensor, the pre-vibrating slurry mold trolley is simultaneously positioned with the vibration mechanism. The lower surface of the vibrating plate 03 is provided with a second vibration motor 04. The left and right ends of the lower surface of the vibrating plate 03 are respectively connected to the vibration table fixing seat 01 through the second vibration spring 02.

[0051] In this embodiment, the positioning mechanism not only ensures that the vibration table is tightly connected to the bottom of the mold groove to guarantee the vibration effect, but also allows the vibrating rods to be distributed at the optimal position of the slurry inside the mold groove to guarantee the vibration effect.

[0052] Example 4

[0053] Based on Example 3, this example further discloses:

[0054] like Figure 1 , 2 As shown in Figure 3, support plates 001 are respectively provided on both sides of the assembly line track where the vibration table is located. The top of the two support plates 001 is fixedly connected to a third connecting plate 002. The third connecting plate 002 is connected to the vibration mechanism through a driving mechanism.

[0055] like Figure 1 , 2As shown in Figures 3, 4, and 7, the vibrating mechanism includes a fixed plate 20 horizontally positioned below the third connecting plate 002. A first force-applying plate 005 is positioned above the third connecting plate 002. The driving mechanism includes a second cylinder 006, which is longitudinally positioned at the center of the top of the third connecting plate 002. The fixed end of the second cylinder is fixedly connected to the upper surface of the third connecting plate 002, and the telescopic end is fixedly connected to the lower surface of the first force-applying plate 005. The four corners of the lower surface of the first force-applying plate 005 are connected to a second force-applying plate 003 via second guide rods 004 that penetrate the third connecting plate 002 and are slidably connected to it. A third cylinder 80 is positioned at the center of the bottom of the second force-applying plate 003. The fixed end of the third cylinder 80 is connected to the first force-applying plate 005. The lower surface of the second force-applying plate 003 is fixedly connected, and the telescopic end is fixedly connected to the upper surface of the fixed plate 20. The covering structure includes a surrounding plate 40 that is sealed and fixedly connected to the bottom end of the second force-applying plate 003. The cross-sectional shape and size of the surrounding plate 40 match the cross-section of the mold groove 3. The bottom end of the surrounding plate 40 is provided with a sealing groove 50. When the surrounding plate 40 moves downward under the drive of the second force-applying plate 003, the sealing groove 50 seals and covers the top end of the mold groove 3. The outer edge of the fixed plate 20 is sealed and slidably connected to the inner surface of the surrounding plate 40 through an elastic rubber ring 30. Several vibrating rods 10 are arranged in a matrix on the lower surface of the fixed plate 20. The first cylinder, the second cylinder, the third cylinder, the transmitting end, the receiving end, and the vibrating rods are electrically connected to the controller through wires.

[0056] It is understandable that during the up-and-down movement of the vibrator, the elastic rubber ring always moves on the inner surface of the enclosure below the air outlet pipe.

[0057] Example 5

[0058] Based on Example 4, this example further discloses:

[0059] like Figure 1 , 2As shown in Figures 4 and 7, the negative pressure guiding unit includes several vent holes 20-1 formed around the vibrating rod 10 on the fixed plate 20, a negative pressure pump 60, and a guiding component disposed on the surface of the vibrating rod 10. The negative pressure pump 60 is fixedly installed on the upper surface of the second force-applying plate 003. The input end of the negative pressure pump 60 is connected to the air outlet pipe 40-1 preset on the side wall of the surrounding plate 40 through a flexible connecting pipe 70. The vibrating rod 10 includes a first guiding section 10-2 located at the upper part and a second guiding section located at the lower part. 10-1, the second guide section 10-1 is used to insert into the slurry 0001 for guiding flow, and the first guide section 10-2 is used to guide the gas overflowing from the slurry 0001. The first guide section includes a plurality of guide grooves 10-4 arranged longitudinally around the axis of the rod on the outer surface of the first guide section 10-2. The second guide section 10-1 includes multiple rows of protruding structures 10-3 arranged longitudinally on the outer surface of the rod. The protruding structures 10-3 are spherical or ellipsoidal. The lower part of the 10-3-1 structure is cut into a horizontal structure 10-3-2. Adjacent columns of raised structures 10-3 are arranged alternately. When the vibrator is quickly inserted downwards into the slurry 0001, the horizontal structure 10-3-2 compresses the air bubbles within the slurry, causing them to move upwards along the spherical or ellipsoidal surface (during rapid insertion of the vibrator, there is a momentary gap between the vibrator and the slurry for the air bubbles to escape), and overflow upwards along the gaps in the raised structures 10-3. When the vibrator 10 is slowly pulled upwards, the horizontal structure 10-3... -2 By lifting, a negative pressure is formed in the slurry (because the horizontal structure tightly squeezes the slurry when it is inserted downwards, a negative pressure is formed when it is lifted), which attracts the gas in the surrounding slurry to flow into the space around the second guide section 10-1. The vibrator is lifted and pulled repeatedly, and the gas in the slurry is attracted and guided at the same time as it is vibrated. The gas output along the second guide section moves upward along the guide groove 10-4 under the negative pressure attraction at several vent holes 20-1, passes through the vent holes 20-1 and enters the negative pressure pump 60 and is discharged.

[0060] The fixing plate 20 is slidably connected to the second force-applying plate 003 via a third guide rod 009 that passes through it. A sealing guide cylinder 008 is also fixedly connected to the upper end of the second force-applying plate 003, and the third guide rod 009 is slidably connected to the sealing guide cylinder 008. That is, the bottom end of the sealing guide cylinder is sealed and fixed to the upper port of the second force-applying plate, which has a sliding hole, and the top end of the sealing guide cylinder is closed, thus achieving the guiding function while avoiding damage to the sealing effect of the mold groove. To further improve ease of use, a clearance hole 007 for the sealing guide cylinder to pass through is also provided on the third connecting plate 002.

[0061] In this embodiment, the vibrator is preferably an electric vibrator, the specific structure of which will not be described in detail. The vibrator of this invention is provided with a flow guiding component on its body, which, together with the vent and negative pressure pump, constitutes a complete negative pressure flow guiding unit. Compared with simply providing negative pressure in the mold groove, this invention precisely controls the direction of airflow, thereby enabling the gas in the slurry around each vibrator to be uniformly discharged, which in turn makes the vibration effect of the slurry more uniform, ensures the uniformity of slurry processing, and helps to improve the structural strength of the paving slab.

[0062] Example 6

[0063] Based on Example 5, this example further discloses:

[0064] like Figure 1 , 2 As shown in Figure 4, the monitoring unit includes a vision sensor 90 spaced between the vibrating rods 10 in adjacent rows. The vision sensor 90 is connected to the controller via a wire. When the controller determines that the vibration and / or compaction has reached the preset standard (e.g., the amount of air bubbles or slurry is reduced to a certain level), the first cylinder 03-2 releases the fixation of the mold groove 3, and the pre-vibrating slurry mold trolley carries the vibrated and / or compacted slurry 0001 along the assembly line track to the next station.

[0065] Example 7

[0066] Based on Example 6, this example discloses:

[0067] A processing method for a high-density concrete pavement slab vibratory compaction equipment, such as... Figure 1-8 As shown, a high-density concrete pavement slab vibratory compaction equipment is used, which includes the following steps:

[0068] Step S1: As the pre-vibrating slurry mold trolley moves away from the previous station and toward the vibrating table, the controller starts the first vibration motor to pre-vibrate the slurry in the mold groove.

[0069] Step S2: When the pre-vibration slurry mold trolley moves above the vibration table and triggers the through-beam photoelectric sensor, the first cylinder actuates to fix the mold slot.

[0070] Step S3: The second cylinder is activated, the surrounding plate and the mold groove cover are combined to form a sealing structure, and the vibrating rod is inserted into the slurry in the mold groove.

[0071] Step S4: The controller starts the third cylinder to insert the vibrating rod into the slurry to the set depth and starts the pre-vibration quality detection. During the pre-vibration quality detection, the vibrating rod is started to vibrate. If the floating slurry or air bubbles on the surface of the slurry do not decrease to a certain extent after a certain period of vibration, it means that the pre-vibration has compacted the slurry. Then the first cylinder is released, and the pre-vibration slurry mold trolley moves to the next station.

[0072] Step S5: When the pre-vibration quality test fails to meet the standard, start the vibration table and negative pressure pump, and combine the high-frequency vibration of the vibration table with the vibration of the vibrating rod.

[0073] Step S6: When the floating slurry or bubbles on the slurry surface detected by the vision sensor are reduced to the set level, it means that the slurry processing is completed. The controller releases the first cylinder, causing the pre-vibration slurry mold trolley to move to the next station and take over the slurry processing of the next pre-vibration slurry mold trolley.

[0074] Through the above settings, the present invention realizes the automated processing of slurry in the prefabrication production line of the pavement panel. The entire device can be integrated into the production line, which can greatly improve production efficiency and slurry processing quality.

10. A processing method for a high-density concrete pavement slab vibratory compaction equipment, characterized in that: The high-density concrete pavement slab vibratory compaction equipment as described in claim 9 includes the following steps: Step S1: As the pre-vibrating slurry mold trolley moves away from the previous station and toward the vibrating table, the controller starts the first vibration motor to pre-vibrate the slurry in the mold groove. Step S2: When the pre-vibration slurry mold trolley moves above the vibration table and triggers the through-beam photoelectric sensor, the first cylinder actuates to fix the mold slot. Step S3: The second cylinder is activated, the surrounding plate and the mold groove cover are combined to form a sealing structure, and the vibrating rod is inserted into the slurry in the mold groove. Step S4: The controller starts the third cylinder to insert the vibrating rod into the slurry to the set depth and starts the pre-vibration quality detection. During the pre-vibration quality detection, the vibrating rod is started to vibrate. If the floating slurry or air bubbles on the surface of the slurry do not decrease to a certain extent after a certain period of vibration, it means that the pre-vibration has compacted the slurry. Then the first cylinder is released, and the pre-vibration slurry mold trolley moves to the next station. Step S5: When the pre-vibration quality test fails to meet the standard, start the vibration table and negative pressure pump, and combine the high-frequency vibration of the vibration table with the vibration of the vibrating rod. Step S6: When the floating slurry or bubbles on the slurry surface detected by the vision sensor are reduced to the set level, it means that the slurry processing is completed. The controller releases the first cylinder, causing the pre-vibration slurry mold trolley to move to the next station and take over the slurry processing of the next pre-vibration slurry mold trolley.
