Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete precasting technology, and in particular to a factory-made small-scale concrete precast block precasting vibration device. Background Technology
[0002] Currently, the production of precast concrete blocks saves construction time in highway, bridge, waterway, and building construction. In the precasting process, for the factory prefabrication of small, interconnected precast concrete blocks, the current method involves placing multiple precast block molds on a single steel frame mold. After pouring the concrete, the entire steel frame mold is placed on a vibrating platform to compact the concrete. However, this process involves high vibration force, significant environmental impact, and large space requirements, which can also affect continuous construction. Utility Model Content
[0003] The purpose of this invention is to provide a factory-produced small-scale precast concrete block vibration device to solve the problems encountered in the background art.
[0004] To achieve the above purpose, the technical solution of the utility model is as follows:
[0005] A precast concrete block vibratory compaction device for factory production includes a steel beam and a formwork support. The bottom two sides of the steel beam are fixed to the workbench by columns. At least one pulley block mechanism is installed at the bottom of the steel beam. The working end of the pulley block mechanism is connected to a plate vibrator. The formwork support is located at the bottom of the steel beam. At least one precast concrete block mold is installed on the top of the formwork support.
[0006] In the above scheme, each pulley block mechanism includes a fixed pulley, a balance cable, and a movable pulley. Two fixed pulleys are provided and fixed to the bottom of the steel beam. The two fixed pulleys are slidably connected to the movable pulley via the balance cable. The plate vibrator is suspended from the working end of the movable pulley. The plate vibrator is suspended from the movable pulley by a sling, and the movable pulley is placed on the balance cable. The balance cable is reversed by the fixed pulley, with its left side fixed to the steel beam by an anchoring end, and its right side connected to a winch.
[0007] The bottom of the movable pulley is connected to a sling, and the movable pulley is connected to the plate vibrator via the sling. As a preferred embodiment, one end of each pulley block is connected to an anchor end via a balance cable, and one end of each pulley block is connected to a winch via a balance cable.
[0008] In the above scheme, a guide beam is fixed between the two columns, and guide rods are provided in the guide beam according to the number of pulley blocks. The plate vibrator vibrates the bottom mold through the guide rods. This involves two scenarios:
[0009] In the first scenario, the two guide rods are grouped together and fixedly connected to the bottom of the guide beam. The guide rods limit the direction of movement of the base of the flat vibrator.
[0010] The second scenario: Two guide rods are grouped together and movably connected to the bottom of the guide beam. The guide beam has an opening for the guide rods to pass through. The bottom end of each guide rod is fixed to the base of the plate vibrator. A guide rod made of steel pipe is welded to the upper part of the plate vibrator. The guide rod controls the position of the plate vibrator through the guide beam. A guide hole, 1mm larger than the outer diameter of the guide rod, is opened at the corresponding position on the guide beam.
[0011] In the above scheme, a bottom mold is fixed to the top of the template support, and the mold is installed on the bottom mold. As a preferred embodiment, rollers are provided on both sides of the bottom of the template support, and the template support moves at the bottom of the steel beam via the rollers. The template support, together with the mold, is placed on the rollers during construction and can slide in one direction. The rollers and the columns supporting the steel beam and guide beam are fixed to the ground.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a small plate vibrator to vibrate the concrete precast mold of small precast blocks, which has little impact on the surrounding environment. The plate vibrator is uniformly suspended by a balance cable, so that each plate vibrator exerts the same vibration pressure on the concrete in each mold. The use of guide beam and guide rod structure can ensure that each plate vibrator can quickly align with the mold to be vibrated. Attached Figure Description

[0020] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.
[0021] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.
[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] Example 1, as Figure 1-5 As shown, a precast concrete block vibratory compaction device for factory production includes a steel beam 1 and a formwork support 3. The bottom sides of the steel beam 1 are fixed to a workbench surface via columns 11. The workbench surface can be a floor or a flat concrete road surface. At least one pulley block mechanism is installed at the bottom of the steel beam 1. The working end of the pulley block mechanism is connected to a plate vibrator 22, which performs vibration compaction on the mold 31.
[0024] The formwork support 3 is located at the bottom of the steel beam 1, and at least one precast concrete block mold 31 is installed on the top of the formwork support 3. This mold 31 is a small precast concrete mold for producing precast blocks in batches, meeting the construction requirements for various precast works. Each mold 31 is equipped with a flat vibrator 22. The shape of the mold 31 can be set as needed; for example, the paving stones used for the waterway bank can be square or polygonal.
[0025] Each pulley block mechanism includes a fixed pulley 13, a balance cable 14, and a movable pulley 15. Two fixed pulleys 13 are provided and fixed to the bottom of the steel beam 1. The two fixed pulleys 13 are slidably connected to the movable pulley 15 via the balance cable 14. The plate vibrator 22 is suspended from the working end of the movable pulley 15. Specifically, the bottom of the movable pulley 15 is equipped with a hook, through which a lifting cable 23 is connected. The movable pulley 15 is connected to the plate vibrator 22 via the lifting cable 23. The hook on the movable pulley 15 greatly facilitates assembly and disassembly, and the raising or lowering of the pulley block mechanism provides overall control of the plate vibrator 22.
[0026] To achieve unified control of the pulley block mechanism, an anchor end 12 is connected to one end of each pulley block mechanism via a balance cable 14. A winch 16 is also connected to one end of each pulley block mechanism via the balance cable 14 to loosen and tension the balance cable 14. When the winch 16 operates, it drives multiple pulley block mechanisms pulled by the same balance cable 14. Because the pulley block mechanism can save effort and change the direction of force, it reduces construction difficulty and allows multiple flat vibrators 22 to be pulled up simultaneously on the same production line to vibrate the mold 31.
[0027] In Example 2, based on Example 1, a guide beam 2 is fixed between the two columns 11. The guide beam 2 is provided with guide rods 21 according to the number of pulley block mechanisms. The plate vibrator 22 vibrates the bottom mold 31 through the guide rods 21. The guide rods 21 guide the movement of the plate vibrator 22, so as to more accurately vibrate the bottom mold 31.
[0028] There are two installation options for the guide rod 21: fixed and movable.
[0029] The fixed structure consists of two guide rods 21 fixedly connected to the bottom of the guide beam 2. The guide rods 21 limit the direction of movement of the base of the plate vibrator 22. When the guide rods 21 are fixed, the movement of the plate vibrator 22 is guided by the guide rods 21.
[0030] The movable structure consists of two guide rods 21 connected movably to the bottom of the guide beam 2. The guide beam 2 has openings for the guide rods 21 to pass through. The bottom end of the guide rods 21 is fixed to the base of the plate vibrator 22. When the guide rods 21 are movable, a guide hole 1mm larger than the outer diameter of the guide rods 21 is provided at the corresponding position on the guide beam 2. The movement of the plate vibrator 22 is guided by the guide beam 2, preventing the plate vibrator 22 from shaking.
[0031] In Example 3, based on Example 1, a bottom mold 32 is fixed to the top of the template support 3. The bottom mold 32 is a steel plane, and the template support 3 supports the bottom mold 32. The mold 31 is installed on the bottom mold 32. The bottom mold 32 is set to provide the same horizontal height for all molds 31, which facilitates the overall lowering of multiple flat vibrators 22 to vibrate multiple molds.
[0032] As a preferred embodiment, the formwork support 3 is equipped with rollers 33 on both sides of its bottom. The formwork support 3 moves along the bottom of the steel beam 1 via the rollers 33. With the steel beam 1 fixed, by moving the position of the formwork support 3, multiple molds 31 in each row can be vibrated simultaneously. After vibrating one row, the support 3 can move to the next row for vibration work.
[0033] In addition, a rubber ring 24 is provided around the base of the plate vibrator 22. The lower outer part of the rubber ring 24 has a funnel-shaped structure, and the ring is 40mm high. The internal shape of the rubber ring 24 is the same as the outer shape of the mold 31, which serves to surround the mold 31. After the plate vibrator 22 is lowered, the rubber ring 24 surrounds the mold 31, preventing the slurry inside the mold 31 from overflowing during vibration. In addition, the funnel-shaped structure of the lower outer part of the rubber ring 24 also serves as a guide.
[0034] Referring to Examples 1-3, the following describes a method for using a factory-made small-scale precast concrete block vibratory compaction device, including the following steps:
[0035] Step 1: Place the formwork support along with the molds on the rollers on the working surface. The horizontal movement distance of the formwork support is constant and equal to the distance between the two rows of molds. After pouring a fixed amount of small blocks, push the formwork support to move a constant distance and place the row of molds with the poured concrete directly under the steel beam.
[0036] Step 2: Remotely start the winch, lower the balance cable, so that the plate vibrator falls on the mold and the balance cable has appropriate tension. Start the vibrator to vibrate the concrete, and loosen the balance cable while vibrating.
[0037] Step 3: After vibrating for 30 seconds, use a winch to tension the balance cable and lift the plate vibrator.
[0038] Step four: Perform reciprocating vibration until all molds are vibrated.
[0039] This invention employs a small plate vibrator 22 to vibrate the concrete precast mold 31 of small precast blocks, minimizing its impact on the surrounding environment. The plate vibrator 22 is uniformly suspended by a balance cable 14, ensuring that each plate vibrator 22 applies the same vibration pressure to the concrete in each mold 31. The use of a guide beam 2 and guide rod 21 ensures that each plate vibrator 22 can quickly align with the mold 31 to be vibrated. A funnel-shaped rubber ring 24 is provided around the vibrator for precise guidance and to prevent grout loss.
