Description

Technical Field

[0001] This utility model relates to the field of wind power construction technology, and in particular to an airborne vibration device for large-volume concrete plastering. Background Technology

[0002] With the rapid development of new energy sources, the capacity of individual wind turbines is increasing, and the radius of the extended foundations used for wind turbine installation is also growing. The finishing work on the sloped surface of the extended foundation has become a crucial factor restricting the foundation's formation. Traditionally, the finishing work on the sloped surface of wind turbine extended foundations is mainly done manually. However, the long pouring time of the wind turbine extended foundation leads to high labor intensity. Workers experience significant physical fatigue, slowed movements, and insufficient energy during the finishing process, resulting in a rushed and hurried completion of the final finishing work. The consequence is poor sloped surface formation, numerous cracks, and a significant impact on the durability of the wind turbine extended foundation.

[0003] Many mortar finishing devices exist on the market, but most are small, handheld vibratory finishing devices that still require considerable manual labor. Among the published mortar finishing devices, such as the one described in patent CN202420079742.7, a building mortar uniform finishing machine, its overly complex structure leads to difficult maintenance and high costs. Furthermore, it is not suitable for finishing the sloping surfaces of fan extension foundations. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high labor intensity, poor forming effect, insufficient efficiency and high equipment cost in the traditional construction and plastering process in the prior art, and to propose an airborne vibration device for plastering large volume concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An airborne vibration device for large-volume concrete plastering includes a quick-connect device, channel steel, and connecting reinforcing bars. The device is characterized by having two symmetrically arranged channel steels with their openings facing upwards; several connecting reinforcing bars are disposed between the two channel steels; and the quick-connect device includes a connecting base and two U-shaped steel plates symmetrically arranged at both ends of the connecting base.

[0007] Preferably, the centerline of the connecting steel bar is perpendicular to the inner surface of the two channel steels, and several connecting steel bars form a ladder-shaped structure with the two channel steels.

[0008] Preferably, a rotating connecting seat is fixedly provided in the middle of the two channel steels.

[0009] Preferably, a stepper motor is fixed to the bottom surface of the connecting base, and the output shaft of the stepper motor is fixedly connected to the rotating connecting seat.

[0010] Preferably, one end of the channel steel is symmetrically provided with two vertical T-shaped grooves, and the other end is symmetrically provided with two T-shaped rails that match the T-shaped grooves; each of the outer surfaces of the two channel steels is provided with a mounting hole near the T-shaped grooves and T-shaped rails; a connecting plate is connected to the outside of the mounting hole by connecting bolts, and the connecting plate is symmetrically provided with mounting holes.

[0011] Preferably, the bottom surfaces of the two channel steels are in the same plane.

[0012] Preferably, the openings of the U-shaped steel plates are opposite to each other and both point towards the inside of the connecting base.

[0013] Preferably, the upper surface of the U-shaped steel plate is provided with a plurality of mounting holes, and the mounting holes on the two U-shaped steel plates are symmetrical.

[0014] Compared with the prior art, the present invention provides an airborne vibration device for large-volume concrete plastering, which has the following beneficial effects.

[0015] 1. This utility model uses a vibratory smoothing working surface formed by the bottom surfaces of two channel steels to perform vibratory smoothing, which completely eliminates the need for manual participation in the smoothing work. This effectively solves the problem of reduced physical strength and energy for workers pouring large volumes of concrete, speeds up the finishing work in the later stages and accelerates the construction progress, ensuring quality while effectively shortening the construction cycle and increasing project benefits.

[0017] 3. This utility model combines the two processes of vibration and finishing into one. At the same time, the hydraulic vibratory compactor can be turned off to finish the slope of the fan extension foundation multiple times according to the site conditions. Therefore, the concrete slope is well formed, preventing the concrete from peeling and uneven slope.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-7 An airborne vibration device for large-volume concrete plastering includes a quick-connect device 1, channel steel 2, and connecting reinforcing bars 3. The channel steel 2 consists of two symmetrically arranged sections with their openings facing upwards. Several connecting reinforcing bars 3 are positioned between the two channel steel 2 sections. The quick-connect device 1 includes a connecting base 101 and two U-shaped steel plates 102 symmetrically arranged at both ends of the connecting base. This invention utilizes U-shaped steel plates 102, which can be selected according to specific needs. Alternatively, lower-cost components can be chosen to assemble the device, tailored to site requirements. The structure is simple and reliable, easy to process, with easily replaceable parts, low manufacturing cost, reusability, convenient maintenance, and quick and easy installation and dismantling, thus reducing construction costs.

[0029] The centerline of the connecting steel bar 3 is perpendicular to the inner surface of the two channel steels 2, and several connecting steel bars 3 and two channel steels 2 form a ladder-shaped structure, which ensures the strength of the overall structure, reduces the risk of damage during use, and extends the service life of the device.

[0030] The bottom surfaces of the two channel steels 2 are in the same plane, and the bottom surfaces of the two channel steels 2 are the working surfaces for vibration smoothing, ensuring construction accuracy by ensuring that they are in the same plane.

[0031] A rotating connecting seat 204 is fixedly provided in the middle of the two channel steels 2. A stepper motor 5 is fixed on the bottom surface of the connecting base 101, and the output shaft of the stepper motor 5 is fixedly connected to the rotating connecting seat 204. Because this utility model is connected to an excavator (with the bucket removed) for vibratory finishing work, the finishing angle or finishing path on the inclined plane needs to be constantly adjusted during vibratory finishing. However, most excavators on the market cannot rotate their buckets and can only rely on the rotation of the cab, which causes inconvenience and blind spots during finishing work. Therefore, to facilitate work, the stepper motor 5 is designed to rotate the two channel steels 2 at an angle. Figure 7 As shown, the two channel steels 2 can be adjusted to any angle or path when working on the inclined plane, so that the operator can find a better vibration leveling angle without rotating the cockpit.

[0032] The channel steel 2 has two vertical T-shaped grooves 201 symmetrically arranged at one end, and two T-shaped rails 202 symmetrically arranged at the other end to match the T-shaped grooves 201. The T-shaped rails 202 are inserted into the T-shaped grooves 201 to form a mortise and tenon structure. Each of the outer surfaces of the two channel steels 2 has a mounting hole 103 near the T-shaped grooves 201 and the T-shaped rails 202. A connecting plate 401 is connected to the outside of the mounting hole by a connecting bolt 4. The connecting plate 401 has symmetrical mounting holes 103. The connecting bolt 4 is inserted into the mounting hole 103. The connecting plate 401 has two mounting holes that match the mounting holes 103 of the channel steel. The two sets of ladder-shaped channel steel 2 can be fixedly connected by the connecting plate 401, connecting bolt 4 and nut. The mortise and tenon structure plays a positioning role, ensuring that the lower surfaces of the two sets of ladder-shaped channel steel 2 are in the same plane. Multiple sets of ladder-shaped channel steel 2 can be connected in this way. Multiple sets of ladder-shaped channel steel 2 form a longer working surface and are firmly connected. Moreover, from the position of the hydraulic plate vibratory compactor 6, one end is longer than the other end, so that it can vibrate and smooth the concrete surface at a distance on the slope of the fan extension foundation. Because it is fastened by the connecting bolt 4 and the connecting plate 401, the installation, dismantling and maintenance are relatively convenient and quick. If necessary, connecting bolt 4, connecting plate 401 and nut can be added to the side of the two channel steel 2 and the connecting reinforcing bar 3 to further enhance the structural stability. This is not shown in this embodiment and the attached drawings.

[0033] The U-shaped steel plates 102 have openings facing each other and both pointing towards the interior of the connecting base 101. The upper surface of each U-shaped steel plate 102 has several mounting holes 103. This invention uses three through-holes for screws, the specific choice depending on actual needs. The mounting holes 103 on the two U-shaped steel plates 102 are symmetrical. A hydraulic plate vibratory compactor 6 is fitted inside each of the two U-shaped steel plates 102. The quick-connect device 1 is connected to the hydraulic plate vibratory compactor 6 via the mounting holes 103 and secured with connecting bolts 4 and nuts. The hydraulic plate vibratory compactor 6 provides the power required for vibratory troweling of the entire device. Figure 5 As shown, installation, dismantling, and maintenance are relatively convenient and quick due to the fastening with connecting bolts 4.

[0034] Working process: The various components or structures of this utility model can be connected by welding, depending on the actual situation. It is essential to ensure that the bottom surfaces of the two channel steels 2 are on the same plane and symmetrical to the two U-shaped steel plates 102. If the length is insufficient, the T-shaped slide rails 202 of one set of ladder-shaped channel steels 2 can be inserted into the T-shaped slide grooves 201 of another set of ladder-shaped channel steels, forming a mortise and tenon structure. This ensures that the lower surfaces of multiple sets of ladder-shaped channel steels 2 are on the same plane. Then, connecting bolts 4, connecting plates 401, and nuts are used to connect adjacent sets of ladder-shaped channel steels 2. In this way, multiple sets of ladder-shaped channel steels 2 form a sufficiently long working surface. After assembling this utility model, the hydraulic plate vibratory compactor 6 is fitted inside the U-shaped steel plate 102 and connected to the hydraulic plate vibratory compactor 6 via the mounting holes 103 using connecting bolts 4 and nuts. Finally, the excavator is connected to the hydraulic plate vibratory compactor 6. During the later stages of pouring the inclined surface of the wind turbine expansion foundation, when finishing the slope, an excavator equipped with a hydraulic plate vibratory tamper 6 and this utility model is used. The longer end of the hydraulic plate vibratory tamper 6 is positioned towards the concrete surface further away. The excavator can move along the edge of the inclined surface, and the hydraulic plate vibratory tamper 6 transmits its vibration force to the working surface formed by the two channel steels 2 of this utility model for compacting and finishing the concrete. Simultaneously, a pump truck is used to replace manual labor in compacting and finishing the inclined surface of the wind turbine expansion foundation, combining the two processes into one. As the finishing work progresses, to improve the surface accuracy of the concrete surface of the inclined surface of the wind turbine expansion foundation, the hydraulic plate vibratory tamper 6 can be turned off to perform multiple finishing processes on the inclined surface of the wind turbine expansion foundation, depending on the site conditions.
