Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete technology, specifically to an integrated machine for concrete slab pouring and compaction. Background Technology
[0002] Concrete slabs are slab-shaped building materials made by casting and curing cement as a binder, supplemented with aggregates (such as sand and stone), water, and admixtures. They can be prefabricated in factories and produced in a standardized manner, commonly used for floor slabs and wall panels. After casting, concrete slabs need to be vibrated to ensure internal compaction and prevent defects such as honeycomb and pitting.
[0003] Current integrated concrete pouring and compaction machines mainly consist of only one vibrating table. After the pouring tank pours concrete slurry into the mold on the vibrating table, the table then compacts it. However, after prolonged use, it has been found that using only one vibrating table to compact concrete slabs leads to the following defects: First, excessively long compaction time causes aggregate to settle, cement slurry to float, and concrete slurry to separate. Second, excessively short compaction time creates voids, resulting in honeycomb and pitted surfaces. The compaction time cannot be effectively controlled, leading to a certain probability of defective products.
[0004] Therefore, a concrete slab pouring and compaction integrated machine is designed to effectively control the compaction effect, thereby improving the finished quality of the concrete slab. Utility Model Content
[0005] The purpose of this invention is to provide an integrated machine for concrete slab pouring and compaction to solve the problems described in the background art.
[0006] The technical solution of this utility model is implemented as follows:
[0007] A concrete slab pouring and compaction integrated machine includes a controller, a mold pushing component, a quantitative feeding component, three vibrating tables spaced at the front, middle, and rear, and two conveyor belts. The two conveyor belts are respectively located within the intervals between the three vibrating tables for connecting them. Each vibrating table includes a base frame, with multiple lower support rods fixedly mounted on the upper end of the base frame. Springs are connected to the upper ends of the lower support rods, and upper support rods are mounted on the top of the springs. A horizontally mounted support plate for supporting the mold is mounted on the top of the upper support rods, and a vibration motor is mounted at the bottom of the support plate. The front-end vibrating table is located below the quantitative feeding component to receive the material discharged by the quantitative feeding component. The vibration frequency of the vibration motor of the front-end vibrating table is higher than that of the vibration motor of the middle vibrating table, and the vibration frequency of the vibration motor of the middle vibrating table is higher than that of the vibration motor of the rear vibrating table. The mold pushing component is located on the left and right sides of the vibrating table and the conveyor belt to push the mold on the front-end and middle vibrating tables onto the conveyor belt. The mold pushing component, the quantitative feeding component and the vibration motor are electrically connected to the controller.
[0008] When using the above method, the mold is placed on the front-end vibrating table, and the quantitative feeding component is controlled to output concrete slurry. After the concrete slurry falls into the mold, the front-end vibrating table continues to vibrate. After a certain period of vibration, the mold pushing component pushes the mold on the front-end vibrating table onto the conveyor belt between the front-end and middle-end vibrating tables. Under the action of the conveyor belt, the mold enters the middle-end vibrating table, which continues to vibrate. After a certain period of vibration, the mold pushing component pushes the mold on the middle-end vibrating table onto the conveyor belt between the middle-end and rear-end vibrating tables. Under the action of the conveyor belt, the mold enters the rear-end vibrating table, which continues to vibrate. After a certain period of vibration, the mold on the rear-end vibrating table is removed, thus completing the compaction operation.
[0009] By setting the vibration frequency of the front-end vibrating table to be higher than that of the middle-end vibrating table to be higher than that of the rear-end vibrating table, the concrete slurry in the mold is rapidly mixed and a large number of air bubbles are expelled under the higher frequency vibration of the front-end vibrating table in a short time. Then, within a controlled time, it enters the middle-end vibrating table at a medium frequency to vibrate out the remaining air bubbles in the voids without vibrating too much and causing the concrete slurry to separate. Finally, within a controlled time, it enters the rear-end vibrating table at a lower frequency to completely vibrate out the air bubbles that have floated to the top of the slurry but have not yet been vibrated out. This effectively removes voids and air bubbles and avoids the separation of concrete slurry.
[0010] After the production rhythm is set, workers can place molds on the front vibrating table according to the rhythm. All three vibrating tables are working continuously, which improves both the compaction effect and production efficiency.
[0011] A further technical solution is that the push mold component includes cylinder brackets located on the left and right sides of the conveyor belt, and a telescopic cylinder located on the cylinder brackets. The telescopic cylinder is also connected to a five-position three-way solenoid valve, which is electrically connected to a controller. The telescopic rod of the telescopic cylinder extends to the front end and is provided with an extension rod. The extension rod and the telescopic rod are arranged collinearly. The front end of the extension rod is also hinged to a rotating rod through a torsion spring hinge. When the rotating rod is not subjected to external force, it is perpendicular to the extension rod under the action of the torsion spring hinge. The front end of the rotating rod extends toward the center of the vibrating table, and the rear end of the rotating rod extends away from the center of the vibrating table. The rear end of the rotating rod abuts against the extension rod, so that the front end of the extension rod cannot rotate toward the front end of the vibrating table. When the rotating rod is subjected to a force along the rear end of the vibrating table, it rotates toward the rear end of the vibrating table.
[0012] When using the above scheme, after setting the time axis of the telescopic cylinder and the quantitative feeding component in the controller, after a certain time has elapsed since feeding is completed, the telescopic cylinders of the front and middle vibrating tables control the telescopic rods to extend forward. During the forward movement, the rotating rod is blocked by the mold, causing it to rotate backward to avoid the mold. When the rotating rod exceeds the mold, and is no longer subject to external force, the torsion spring hinge controls the rotating rod to return to its original position, keeping it perpendicular to the extension rod. At this time, the controller controls the telescopic cylinder's telescopic rod to retract, and the rotating rod blocks the mold, pushing the mold backward (this can also be considered pulling in different coordinate systems), causing the mold to enter the conveyor belt and flow onto the middle vibrating table under the action of the conveyor belt. The working principle of the telescopic cylinders between the middle and rear vibrating tables is the same and will not be described further.
[0013] A further technical solution is that the quantitative feeding component includes an elevated feeding tank and a screw conveyor located at the bottom of the feeding tank. The bottom of the feeding tank is connected to the screw conveyor, the outlet of the screw conveyor is located above the front-end vibrating table, and the screw conveyor is electrically connected to the controller.
[0014] When using the above method, the mixed concrete slurry is poured into the feeding tank, and then discharged quantitatively via a screw conveyor.
[0015] A further technical solution is that the upper surface of the receiving plate is also provided with two first baffles extending along the front and rear direction of the vibration table, and the two first baffles are parallel to each other and spaced apart.
[0016] When using the above solution, setting a first baffle can effectively limit the movement trajectory of the mold on the receiving plate.
[0017] A further technical solution is that the upper end face of the conveyor belt is provided with two second baffles extending along the front-back direction of the conveyor belt. The two second baffles are parallel to each other and spaced apart, and the spacing between the two second baffles is the same as the spacing between the two first baffles.
[0018] When using the above solution, setting a second baffle can effectively limit the movement trajectory of the mold on the conveyor belt.
[0019] A further technical solution is that the front-end vibration table is the first vibration table, the middle vibration table is the second vibration table, and the rear-end vibration table is the third vibration table. The vibration frequency of the vibration motor of the first vibration table is 10,000 to 12,000 times / minute, the vibration frequency of the vibration motor of the second vibration table is 8,000 to 9,000 times / minute, and the vibration frequency of the vibration motor of the third vibration table is 6,000 to 7,000 times / minute.
[0020] When using the above scheme, the vibration time of the first vibration table is 20-25 seconds, after which the pneumatic push rod is activated. The vibration time of the second vibration table is 20-25 seconds, after which the pneumatic push rod is activated. The vibration time of the third vibration table is 20-25 seconds, after which it is removed by the worker or by another mechanism.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. Good compaction effect: The front, middle and rear vibration tables are set up, and the vibration frequency decreases in sequence. This allows the concrete slurry to mix quickly and remove a large number of air bubbles. Then, the remaining voids and air bubbles are vibrated out and stratification is avoided. Finally, the upper layer of air bubbles is completely vibrated out, effectively removing voids and air bubbles.
[0023] 2. High production efficiency: After the production rhythm is set, the three vibrating tables operate continuously, and workers can place the molds in rhythm to achieve high-efficiency production.
[0024] 3. Stable mold pushing: By setting the time axis of the telescopic cylinder and the quantitative feeding component through the controller, the mold is stably pushed by the telescopic cylinder, rotating rod, torsion spring hinge and other components.
[0025] 4. Controllable mold movement trajectory: A first baffle is set to restrict the movement trajectory of the mold on the receiving plate, and a second baffle is set to restrict the movement trajectory of the mold on the conveyor belt, ensuring orderly mold movement. Attached Figure Description
