Description

Technical Field

[0001] This invention relates to the field of concrete processing equipment technology, and more particularly to a concrete precast component processing equipment. Background Technology

[0002] Precast concrete components are building components that are prefabricated in a factory. The manufacturing process begins by pouring concrete into molds of a specific shape. To improve production efficiency and ensure component quality, dry-hard concrete is often used in production. A pressure plate is used above the mold to apply pressure and vibration to compact the concrete. This dual force quickly removes air bubbles and achieves high-efficiency compaction. After demolding, the components need to be continuously cured in a curing kiln with constant temperature and humidity to reach their design strength.

[0003] When using a pressure plate above the mold for vibration and compaction, precast concrete components may develop pits or pits on their interior or surface after demolding due to insufficient vibration within the mold. Therefore, existing technologies often employ the method of placing the mold on a base plate and vibrating the entire base plate and mold. However, this method has several drawbacks. First, continuous high-frequency vibration can cause significant alternating stress on the mold's welds, connectors, and main structure, leading to damage and a significantly shortened lifespan. Second, vibrating the entire mold can affect the sealing of various parts of the mold. Finally, the required scale of vibration can result in substantial noise pollution and energy consumption, thus creating limitations.

[0004] Therefore, we propose a precast concrete component processing device. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a precast concrete component processing device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a precast concrete component processing device, comprising:

[0007] Base, frame, molding die, rotating frame, pressure plate and filling mechanism;

[0008] The rotating frame is mounted on the base; the molding die is rotatably connected to the rotating frame; the rotating frame is equipped with a drive motor assembly for driving the molding die to rotate;

[0009] A first movable block is slidably connected to the frame; a pressure plate is slidably connected to the first movable block; the pressure plate and the first movable block are driven by a hydraulic device; a first vibration component is provided on the pressure plate;

[0010] The molding mold is slidably connected to fixed frames on both sides; the base is provided with two sets of upper and lower electric push rods; a sliding electric push rod is connected between the fixed frame and the molding mold; a cover plate is placed on the base; an ejection electric push rod is provided at the bottom of the molding mold to assist concrete in demolding from the molding mold.

[0011] The pressure plate is equipped with a lifting vibration assembly; the lifting vibration assembly extends into the molding mold when the filling mechanism pours concrete into the molding mold; when the first vibration assembly vibrates, the lifting vibration assembly vibrates inside the molding mold while moving upward, thereby vibrating the concrete below inside the molding mold.

[0012] Preferably, the lifting vibration assembly includes a mounting ring, a clamping block, and a vibration rod; the mounting ring is mounted on the pressure plate; a lifting electric push rod is connected between the mounting ring and the vibration rod; an end vibration motor and a polarizing block are disposed inside the vibration rod; the polarizing block is fixedly connected to the output shaft of the end vibration motor.

[0013] By installing a vibratory rod on the pressure plate, the vibratory rod extends into the concrete. During the process of the pressure plate vibrating the concrete, the vibratory rod inside the concrete also vibrates. This vibrates the part of the concrete away from the pressure plate, thus preventing the concrete from receiving less vibration and incomplete air expulsion in the part away from the pressure plate.

[0014] Preferably, the vibrating rod has a feeding channel inside; the feeding channel passes through the vibrating rod; a sealing block is provided at the lower end of the vibrating rod to block the feeding channel; a connecting interface is provided at the upper end of the vibrating rod; the connecting interface is connected to the feeding channel and the connecting interface is connected to the filling mechanism.

[0015] Preferably, the sealing block is slidably fitted with the feeding channel; the lower end of the sealing block is cylindrical and the upper end is inclined; a steel wire rope is slidably connected inside the vibrating rod; one end of the steel wire rope is connected to the sealing block, and the other end protrudes from the upper end of the vibrating rod; a sealing electric push rod is fixedly connected to the vibrating rod; the output end of the sealing electric push rod is connected to the steel wire rope.

[0016] By setting a feeding channel inside the vibrating rod, concrete is added to the molding mold through the feeding channel. This invention adds concrete to the molding mold in two steps, thus avoiding the situation where a large amount of concrete is added at one time, causing concrete to fall onto the top of the molding mold and affecting the contact between the pressure plate and the molding mold.

[0017] Preferably, the pressure plate has a sealing groove; the sealing groove is arranged around the vibrating rod, and a sealing block is slidably connected in the sealing groove; a sealing electric push rod is installed in the sealing groove.

[0018] Preferably, a connecting ring is fixedly connected to the pressure plate; a No. 1 spring is connected between the connecting ring and the mounting ring.

[0019] Preferably, a sliding block is fixedly connected to the output end of the sealing electric push rod; the sliding block and the sealing block are in sliding engagement, and a second spring is connected between the sliding block and the sealing block.

[0020] In this invention, when the vibrating rod vibrates, the sealing electric push rod pushes the sealing block to clamp the vibrating rod, thereby preventing the vibrating rod from moving up and down during the vibration process. At the same time, after the vibrating rod is removed from the molding mold, the vibrating rod is clamped and fixed to prevent the concrete from squeezing the vibrating rod when the concrete is squeezed.

[0021] In this invention, a connecting ring and a first spring are provided between the mounting ring and the pressure plate to protect the lifting electric push rod. Similarly, a sliding block and a second spring are provided before the sealing electric push rod and the sealing block to buffer the vibration generated by the vibrating rod on the sealing electric push rod.

[0022] The beneficial effects of this invention are:

[0023] 1. The present invention provides a vibrating rod on a pressure plate, which extends into the concrete. During the vibration of the concrete by the pressure plate, the vibrating rod inside the concrete also vibrates, thereby vibrating the part of the concrete away from the pressure plate. This prevents the part of the concrete away from the pressure plate from receiving less vibration and the incomplete expulsion of air.

[0024] 2. By setting a feeding channel inside the vibrating rod, the present invention adds concrete to the molding mold through the feeding channel. This allows the present invention to add concrete to the molding mold in two steps, thus avoiding the situation where a large amount of concrete is added at one time, causing concrete to fall above the molding mold and affecting the contact between the pressure plate and the molding mold.

[0030] 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.

[0031] Example 1: Refer to the appendix of the instruction manual. Figures 1 to 4 A precast concrete component processing device, comprising:

[0032] Base 1, frame 11, molding die 12, rotating frame 13, pressure plate 14, and filling mechanism 15;

[0033] The rotating frame 13 is mounted on the base 1; the molding die 12 is rotatably connected to the rotating frame 13; the rotating frame 13 is provided with a drive motor assembly 16 for driving the molding die 12 to rotate;

[0034] A first movable block 17 is slidably connected to the frame 11; a pressure plate 14 is slidably connected to the first movable block 17; the pressure plate 14 and the first movable block 17 are driven by a hydraulic device; a first vibration component 18 is provided on the pressure plate 14;

[0035] The molding mold 12 is slidably connected to the two sides of the fixed frame 2; the fixed frame 2 is in the shape of a c; the base 1 is provided with two sets of upper and lower electric push rods 21; the fixed frame 2 and the molding mold 12 are connected by a sliding electric push rod 22; a cover plate 23 is placed on the base 1; the bottom of the molding mold 12 is provided with an ejection electric push rod 24 to assist the concrete in demolding from the molding mold 12.

[0036] The pressure plate 14 is equipped with a lifting vibration assembly; the lifting vibration assembly extends into the molding mold 12 when the filling mechanism 15 pours concrete into the molding mold 12; when the first vibration assembly 18 vibrates, the lifting vibration assembly vibrates in the molding mold 12 while moving upward, thereby vibrating the concrete below in the molding mold 12.

[0037] In this invention, the lifting vibration assembly includes a mounting ring 3, a clamping block 31, and a vibration rod 32; the mounting ring 3 is mounted on the pressure plate 14; a lifting electric push rod 34 is connected between the mounting ring 3 and the vibration rod 32; an end vibration motor 35 and a polarizing block 36 are provided inside the vibration rod 32; the polarizing block 36 is fixedly connected to the output shaft of the end vibration motor 35.

[0038] In this invention, the forming mold 12 is a combined mold, and a base plate is provided inside the forming mold 12. The base plate can push and compress concrete upward under the push of the electric push rod 24. In this invention, a motor and a lead screw are provided on the frame 11 to drive the first moving block 17 and the filling mechanism 15 to move. First, the worker sprays a release agent into the forming mold 12. Then, the motor and lead screw on the frame 11 drive the filling mechanism 15 to move above the forming mold 12. After the concrete is poured into the forming mold 12, the filling mechanism 15 returns to its original position. Then, the vibrating rod 32 on the pressure plate 14 extends downward into the concrete in the forming mold 12 under the drive of the lifting electric push rod 34. The pressure plate 14 covers the top of the forming mold 12 under the action of the hydraulic device. The first vibration component 18 on the pressure plate 14 vibrates. At the same time, the end vibration motor 35 in the vibrating rod 32 drives the vibrating block to rotate, so that the lower end of the vibrating rod 32 vibrates, thereby the lower end of the vibrating rod 32 vibrates in the concrete in the forming mold 12. Vibration is generated in the concrete, which tamps the bottom concrete, so that the concrete in the mold 12 furthest from the pressure plate 14 can also be tamped. At the same time, the electric push rod 24 is pushed upward to push the bottom plate in the mold 12, thereby squeezing the concrete. The vibrating rod 32 moves upward under the drive of the lifting electric push rod 34 until its lower end is flush with the pressure plate 14. After the tamping and squeezing of the concrete is completed, the pressure plate 14 returns to its original position. The pushing electric push rod 21 above the base 1 pushes the cover plate 23 into the fixed frame 2. The drive motor assembly 16 on the rotating frame 13 drives the mold 12 to flip, so that the cover plate 23 is at the bottom. Then the sliding electric push rod 22 pushes the cover plate 23 downward and pushes the electric push rod 24 to push the bottom plate in the mold 12, so that the formed concrete precast part is separated from the mold 12 and falls onto the cover plate 23. Then the pushing electric push rod 21 above and below the base 1 pushes the cover plate 23 and the concrete precast part away from the bottom of the mold 12.

[0039] The present invention provides a vibrating rod 32 on the pressure plate 14, which extends into the concrete. During the process of the pressure plate 14 vibrating the concrete, the vibrating rod 32 in the concrete also vibrates. Thus, the vibrating rod 32 vibrates the part of the concrete away from the pressure plate 14, thereby preventing the part of the concrete away from the pressure plate 14 from receiving less vibration and the situation where the air is not completely expelled.

[0040] In this invention, a feeding channel 37 is provided inside the vibrating rod 32; the feeding channel 37 passes through the vibrating rod 32; a sealing block 38 is provided at the lower end of the vibrating rod 32 to seal the feeding channel 37; a connecting interface 39 is provided at the upper end of the vibrating rod 32; the connecting interface 39 is connected to the feeding channel 37 and is connected to the filling mechanism 15.

[0041] In this invention, the sealing block 38 is slidably fitted with the feeding channel 37; the lower end of the sealing block 38 is cylindrical and the upper end is inclined; a steel wire rope 4 is slidably connected inside the vibrating rod 32; one end of the steel wire rope 4 is connected to the sealing block 38, and the other end protrudes from the upper end of the vibrating rod 32; a sealing electric push rod 41 is fixedly connected to the vibrating rod 32; the output end of the sealing electric push rod 41 is connected to the steel wire rope 4.

[0042] In this invention, a feeding channel 37 is provided on the vibrating rod 32, and the connecting interface 39 is connected to the filling mechanism 15 through a pipe. When the vibrating rod 32 moves upward, concrete can be added to the concrete in the molding mold 12 through the feeding channel 37 to fill the pits left in the concrete after the vibrating rod 32 moves.

[0043] After the precast concrete component is extruded and formed by the molding mold 12, the total volume of the concrete decreases. Therefore, the filled concrete needs to be compacted. During the compaction process, since a large amount of concrete is added at one time, when it reaches the final stage, some concrete may fall around the top of the molding mold 12. As a result, when the pressure plate 14 presses down on the molding mold 12, this part of the concrete will cause a gap between the molding mold 12 and the pressure plate 14. Therefore, when the filling mechanism 15 of this invention fills the molding mold 12 with concrete, it adds 90% of the total amount of concrete. After the pressure plate 14 contacts the molding mold 12, the vibrating rod 32 adds the last 10% of the concrete to the molding mold 12. Therefore, when the filling mechanism 15 fills the molding mold 12 with concrete, the concrete will not fall onto the top of the molding mold 12.

[0044] In this invention, concrete is added into the molding mold 12 via the vibrating rod 32. After the addition is completed, the sealing electric push rod 41 pulls the sealing block 38 via the steel wire rope 4, so that the sealing block 38 enters the feeding channel 37. A stop block is set in the feeding channel 37 to block the sealing block 38. When compacting the concrete, it is ensured that the lower end of the sealing block 38 is flush with the lower end of the vibrating rod 32.

[0045] The present invention adds concrete to the molding mold 12 by setting a feeding channel 37 in the vibrating rod 32. This means that the present invention adds concrete to the molding mold 12 in two steps, so that the amount of concrete added at one time will not be too large and the concrete will fall on top of the molding mold 12, affecting the contact between the pressure plate 14 and the molding mold 12.

[0046] Example 2: Based on Example 1, refer to the appendix of the instruction manual. Figures 1 to 4 In this invention, a sealing groove 5 is provided on the pressure plate 14; the sealing groove 5 is arranged around the vibration rod 32, and a sealing block 51 is slidably connected in the sealing groove 5; a sealing electric push rod 52 is installed in the sealing groove 5.

[0047] In this invention, a connecting ring 53 is fixedly connected to the pressure plate 14; a first spring 54 is connected between the connecting ring 53 and the mounting ring 3.

[0048] In this invention, a sliding block 55 is fixedly connected to the output end of the sealing electric push rod 52; the sliding block 55 and the sealing block 51 are in sliding engagement, and a second spring 56 is connected between the sliding block 55 and the sealing block 51.

[0049] In this invention, when the vibrating rod 32 vibrates, the sealing electric push rod 52 pushes the sealing block 51 to clamp the vibrating rod 32, thereby preventing the vibrating rod 32 from moving up and down during the vibration process. At the same time, after the vibrating rod 32 is removed from the molding mold 12, the vibrating rod 32 is clamped and fixed to prevent the concrete from squeezing the vibrating rod 32 when the concrete is squeezed.

[0050] In this invention, a connecting ring 53 and a first spring 54 are provided between the mounting ring 3 and the pressure plate 14, which can protect the lifting electric push rod 34. Similarly, a sliding block 55 and a second spring 56 are provided before the sealing electric push rod 52 and the sealing block 51, which can also buffer the vibration when the vibration generated by the vibrating rod 32 is transmitted to the sealing electric push rod 52.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
