Description

Technical Field

[0001] This utility model relates to the field of precast concrete component production technology, specifically to a vibration device for precast concrete components. Background Technology

[0002] Precast components have advantages such as good structural performance and fast construction speed, and are being widely used in various construction projects. The manufacturing of precast components usually involves injecting concrete into a mold through a material placing mechanism, and then vibrating and smoothing the concrete in the mold to ensure the quality of the finished precast components.

[0003] Existing precast concrete components sometimes require on-site molding. During the precasting process, a vibrator needs to be manually inserted into the concrete to compact it. However, due to the resistance of the concrete, the vibrator may become skewed, preventing it from reaching the intended vibration depth. This results in uneven vibration of the concrete, which can lead to problems such as poor compaction at the edges and corners of the finished product and numerous honeycomb and pitted surfaces.

[0004] To address the above problems, this utility model provides a vibration device for precast concrete components. Utility Model Content

[0005] The purpose of this invention is to provide a vibration device for precast concrete components. The device uses a roller conveyor to transport the precast component molds, eliminating the need for manual handling and improving efficiency. The output end of the electric telescopic rod can drive the mounting plate downwards, inserting the vibrator into the concrete inside the precast component mold. This ensures the vibrator remains straight and reaches the predetermined vibration depth. The first and second motors work together to adjust the position of the vibrator, ensuring uniform vibration of the concrete within the precast component mold. This effectively solves the problems of insufficient compaction at the edges and corners and numerous honeycomb and pitted surfaces in the finished product, thus addressing the issues in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration device for precast concrete components, including a roller conveyor. Baffles are provided on both sides of the upper end of the roller conveyor. An electric push rod is provided in the middle of the inner side of each of the two baffles. A clamping plate is provided at the output end of the electric push rod. A rectangular plate is provided above the baffles. A rectangular through hole is opened at the upper end of the rectangular plate. A first slider is slidably arranged inside the rectangular through hole. A lead screw is provided on the side of the first slider. A first motor is provided at the end of the lead screw. An electric telescopic rod is provided at the lower end of the first slider. A mounting plate is provided at the telescopic end of the electric telescopic rod. Two mutually symmetrical second sliders are slidably arranged on the side of the mounting plate. A bidirectional threaded lead screw is provided on the side of the second slider. A second motor is provided at the end of the bidirectional threaded lead screw. A mounting block is provided on the outer side of the second slider. A vibrating rod is provided at the lower end of the mounting block. Vibration motors are provided on both sides of the upper end of the rectangular plate.

[0007] Furthermore, the baffle is fixedly connected to one side of the upper end face of the roller conveyor, the electric push rod is fixedly installed in the middle of the baffle, and the middle side of the clamping plate is fixedly connected to the output end of the electric push rod.

[0008] Furthermore, the side of the first slider is slidably connected to the inner wall of the rectangular through hole, the lead screw passes through the first slider and is threadedly connected to its interior, and the two ends of the lead screw are rotatably connected to the inner wall of the rectangular through hole through bearings. The first motor is fixedly installed in the middle of the side of the rectangular plate, and one end of the lead screw extends outward to the outside of the rectangular plate and is fixedly connected to the output end of the first motor.

[0009] Furthermore, the electric telescopic rod is fixedly installed at the lower end of the first slider, and the telescopic end of the electric telescopic rod is fixedly connected to the upper end face of the mounting plate.

[0010] Furthermore, a groove is provided on the side of the mounting plate, and the second slider is slidably connected to the inner wall of the groove. Both second sliders are penetrated by the same bidirectional threaded screw, which is threadedly connected to the interior of both second sliders. The two ends of the bidirectional threaded screw are rotatably connected to the inner wall of the groove through bearings. The second motor is fixedly installed at one end of the mounting plate, and one end of the bidirectional threaded screw extends outward to the outside of the mounting plate and is fixedly connected to the output end of the second motor.

[0011] Furthermore, the mounting block is fixedly connected to the outer side of the second slider, the vibrating rod is fixedly mounted on the mounting block, the upper end of the vibrating rod is fixedly connected to a flexible shaft, and the end of the flexible shaft away from the vibrating rod is fixedly connected to the output end of the vibration motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model provides a vibration device for precast concrete components. When precast concrete components need to be manufactured, the precast component mold is first placed at the inlet end of a roller conveyor. Then, concrete is added into the precast component mold through a material distribution mechanism. Next, the roller conveyor transports the precast component mold filled with concrete to the bottom of a rectangular plate. Then, the output ends of two electric push rods push the clamping plate towards the precast component mold, fixing the precast component mold. Subsequently, a first motor drives a lead screw to rotate, which moves a first slider above the precast component mold. The first slider moves an mounting plate above the precast component mold. Then, a second motor drives a bidirectional threaded lead screw to rotate, which causes two second sliders to move synchronously in opposite directions. The synchronous movement of the two second sliders causes two mounting blocks to move synchronously in opposite directions, thereby causing the two vibrating blocks to vibrate. The distance between the vibrating rods can be adjusted to accommodate precast component molds of different sizes. Finally, the telescopic end of the electric telescopic rod drives the mounting plate downward, inserting the vibrating rod into the concrete inside the precast component mold. This ensures that the vibrating rod does not deviate and reaches the predetermined vibration depth, allowing the concrete material to vibrate evenly. The purpose of this design is to transport the precast component mold via a roller conveyor, eliminating the need for manual handling and improving efficiency. The output end of the electric telescopic rod can drive the mounting plate downward, inserting the vibrating rod into the concrete inside the precast component mold. This ensures that the vibrating rod does not deviate and reaches the predetermined vibration depth. The first and second motors work together to adjust the position of the vibrating rod, ensuring that the concrete in the precast component mold receives uniform vibration. This effectively solves the problems of insufficient compaction at the edges and corners and numerous honeycomb and pitted surfaces in the finished product. Attached Figure Description
