Description

Technical Field

[0001] The invention relates to the technical field of concrete construction equipment, in particular to a concrete vibrating device. Background Art

[0002] During the concrete construction process, after the concrete pouring is completed, the concrete needs to be vibrated. This is because during the concrete mixing process, due to the viscosity of the cement slurry and the shape and particle size of the aggregate, bubbles and gaps are easily formed inside the concrete. If these bubbles and gaps are not discharged in time, the strength and durability of the concrete will be affected. Through concrete vibration, the particles inside the concrete can be rearranged to discharge bubbles and pores, eliminate the honeycomb surface of the concrete, make the concrete densely combined, improve the strength of the concrete, and ensure the pouring quality.

[0003] At present, vibrating rulers are usually used for vibrating operations, and in practical applications, as the application environment changes, the vibrating area of ​​the vibrating ruler also needs to change accordingly. Therefore, for example, Chinese utility model patent CN221255121U discloses an adjustable concrete vibrating ruler, including a cover plate, the bottom of the cover plate is fixedly connected to a support plate and a first spring, the bottom of the support plate is connected to a support pad, the bottom of the first spring is connected to a square pad, the bottoms of the square pad and the support pad are fixedly connected to the main scale plate, the main scale plate is slidably connected to a secondary scale plate inside, the middle of the top of the cover plate is connected to a motor, the edge of the cover plate is fixedly connected to a guard frame and a baffle, the top of the baffle is fixedly connected to a support rod, the top of the support rod is connected to a shock-absorbing cylinder, and one side of the shock-absorbing cylinder is connected to a handle. The utility model can reduce the vibration wave emitted by the vibration of the motor through the arrangement of the shock-absorbing cylinder and the second spring, and by adjusting the secondary scale plate, the working area of ​​the concrete vibrating ruler is increased, the working range of the concrete vibrating ruler plate is widened, and the work efficiency of the operator is improved.

[0004] However, in the above-mentioned adjustable concrete vibrating ruler, although the working area can be adjusted by adjusting the sub-scale plate, after extending the sub-scale plate to increase the working area, since the main scale plate and the sub-scale plate are split structures, and the vibration waves emitted by the motor vibration are first transmitted to the main scale plate and then to the sub-scale plate, there is a difference in the vibration effect of the main scale plate and the vibration effect of the sub-scale plate. Therefore, during the vibration operation, the consistency of the vibration density and flatness of the same working surface cannot be guaranteed, and the concrete molding quality is poor. Summary of the invention

[0005] The invention provides a concrete vibrating device to solve the technical problem that the existing vibrating equipment cannot ensure the consistency of vibration density and flatness on the same working surface after the working area is increased, and the concrete molding quality is poor.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0029] like Figure 1-Figure 4As shown, the concrete vibrating device of this embodiment includes a mounting platform 100, a driving assembly 200, an operating handle 300 and a vibrating assembly 400. The driving assembly 200 and the operating handle 300 are arranged on the mounting platform 100. The vibrating assembly 400 includes a plurality of vibrating members 410. The vibrating members 410 include a vibrating plate 411 for contacting with a concrete surface to perform a vibrating operation and an eccentric shaft 412 rotatably arranged on the vibrating plate 411 for generating a vibration wave after rotation and transmitting it to the vibrating plate 411. The plate 411 is arranged on the mounting platform 100, and the eccentric shaft 412 in the vibrating piece 410 is connected to the output end of the driving assembly 200, the two adjacent vibrating plates 411 are detachably connected, and the two adjacent eccentric shafts 412 are respectively provided with an axial plug-in structure for axially plugging in with each other to perform angular and radial limiting on the two adjacent eccentric shafts 412, and the vibrating piece 410 is provided with a radial plug-in structure arranged on the eccentric shaft 412 for radially plugging in with the axial plug-in structure to perform axial, radial and angular limiting on the two adjacent eccentric shafts 412.

[0030] like Figure 1 and Figure 2 As shown, optionally, a bearing seat is arranged on the vibration plate 411, and the eccentric shaft 412 is rotatably arranged on the bearing seat. Optionally, the bearing seat is arranged on the vibration plate 411 through a mounting plate. Optionally, the eccentric shaft 412 includes a shaft body and an eccentric wheel fixedly sleeved on the shaft body, and the shaft body is connected to the driving assembly 200. When the driving assembly 200 drives the shaft body to rotate, the eccentric wheel rotates synchronously. Due to its uneven mass distribution, a constantly changing unbalanced torque will be generated. This unbalanced torque will generate a vibration wave that causes reciprocating acceleration and deceleration motion. After being transmitted to the vibration plate 411, it causes the vibration plate 411 to vibrate, and then is transmitted to the concrete surface through the vibration plate 411. During the vibration process, the aggregate particles inside the concrete can flow and rearrange better, reduce the gap, and make the concrete mixture more compact, thereby completing the vibration leveling of the concrete. Optionally, the driving assembly 200 includes a driving motor, a fixed sleeve on the output shaft of the driving motor is provided with a pulley 1, a fixed sleeve on the shaft body is provided with a pulley 2, and the pulley 1 and the pulley 2 are connected by a belt drive.

[0031] like Figure 1-Figure 4As shown, specifically, the concrete vibrating device of the present invention is installed with a driving assembly 200, an operating handle 300 and a vibrating assembly 400 through an installation platform 100. The operator controls the vibrating operation direction of the vibrating device through the operating handle 300. During the vibrating operation, the driving assembly 200 drives the eccentric shaft 412 to rotate, so that the eccentric shaft 412 generates a vibration wave and transmits it to the vibration plate 411, and then the vibration plate 411 contacts the concrete surface to perform the vibration operation; when it is necessary to expand the vibration range, the number of vibrating members 410 can be increased. When two adjacent vibration plates 411 are connected, the adjacent two eccentric wheels are axially plugged into each other through an axial plug-in structure to angularly limit and radially limit the adjacent two eccentric shafts 412, and then the radial plug-in structure is radially plugged into the axial plug-in structure to radially limit the adjacent two eccentric shafts 412. The angular limit makes the two adjacent eccentric shafts 412 connected to each other as a whole, so that when the driving assembly 200 drives one of the eccentric shafts 412 to rotate, the other eccentric shafts 412 rotate synchronously and transmit vibration waves to the corresponding vibration plate 411 synchronously, thereby ensuring the overall vibration effect. Moreover, after axial plug-in, radial plug-in can be quickly performed. The connection and positioning of the two eccentric shafts 412 are simple and easy to disassemble and assemble, which reduces the risk of incorrect installation and makes the maintenance and inspection of the device easier. It is more beneficial for construction sites that need to frequently disassemble and assemble the device for corresponding adjustments. The present solution connects the two adjacent eccentric shafts 412 into a whole through an axial plug-in structure and a radial plug-in structure, thereby ensuring the overall vibration effect. Compared with the prior art, it can ensure the consistency of the vibration density and flatness of the same working surface, improve the quality of concrete molding, has strong practicality, and is suitable for wide promotion and application.

[0032] like Figure 1 As shown, it should be understood that the length of the vibration plate 411 connected to the mounting platform 100 in the vibration assembly is relatively long, and the corresponding length of the eccentric shaft 412 is relatively long. Therefore, the eccentric shaft 412 can be supported by arranging a bearing seat in the mounting platform 100 to ensure the stability of the rotation of the eccentric shaft 412.

[0033] like Figure 4 As shown, in this embodiment, the axial plug-in structure includes a square head 510 arranged on the axial first end of the eccentric shaft 412 and a square groove 520 provided on the axial second end of the eccentric shaft 412 for axial plug-in cooperation with the square head 510 on the axial first end of the adjacent eccentric shaft 412. Specifically, when the two connected vibration plates 411 are connected, the square head 510 is axially inserted into the square groove 520, so that the two adjacent eccentric shafts 412 are radially limited and angularly limited through the axial plug-in cooperation of the square head 510 and the square groove 520.

[0034] like Figure 4As shown, in this embodiment, a plug-in groove 1 is radially opened on the square head 510, a plug-in groove 2 connected with the square groove 520 is radially opened on the second axial end of the eccentric shaft 412, and the radial plug-in structure includes a combined shell 610 arranged on the plug-in groove 2 and a plug-in part 620 penetrated through the combined shell 610 and used for radially inserting into the plug-in groove 1 sequentially, and the combined shell 610 is radially opened with a plug-in cavity connected with the square groove 520. Specifically, when the square head 510 and the square slot 520 are axially plugged in, the plug-in slot one and the plug-in slot two are arranged correspondingly in the radial direction. At this time, the connector 620 is radially penetrated through the combined shell 610 on the plug-in slot two and inserted into the plug-in slot one, thereby axially limiting, radially limiting and angularly limiting the two adjacent eccentric shafts 412, that is, the two adjacent eccentric shafts 412 are connected into a whole through the axial plug-in structure and the radial plug-in structure. The axial plug-in structure can reduce the difficulty of plug-in of the radial plug-in structure, so that disassembly and installation can be achieved more quickly.

[0035] like Figure 5 As shown, in this embodiment, the plug-in 620 includes a pull rod 621 radially penetrating the combined shell 610, a wedge block 622 fixedly connected to the inserted end of the pull rod 621, a knob 623 fixedly connected to the extended end of the pull rod 621 for abutting against the outer wall of the combined shell 610 and limiting the position, and a compression spring 624 sleeved on the pull rod 621 and arranged in the plug-in cavity. Specifically, during the process of the square head 510 being inserted into the square slot 520, the square head 510 contacts the surface of the wedge block 622, so that the wedge block 622 is affected by its own inclined surface, forcing the wedge block 622 to move away from the square slot 520 until it completely enters the plug-in cavity and compresses the compression spring 624. After the square head 510 is plugged in place, the plug-in slot 1 and the plug-in slot 2 are arranged correspondingly. At this time, under the action of the compression spring 624, the wedge block 622 is radially inserted into the plug-in slot 1 to limit the position of the two adjacent eccentric shafts 412. It should be understood that the inclined surface of the wedge block 622 is arranged toward the square head 510. It should be understood that the square head 510, the square slot 520, the wedge block 622 and the compression spring 624 work together to achieve radial plug-in fit while axial plug-in fit, greatly increasing the installation speed.

[0036] like Figure 5As shown, in this embodiment, the plug-in component 620 further includes a limit plate 625 arranged on the combined shell 610, and a rotating plate 626 rotatably sleeved on the extended end of the pull rod 621, which is used to radially abut and limit with the limit plate 625, so that the wedge block 622 is radially away from the square groove 520. Specifically, when separating two adjacent eccentric shafts 412, the knob 623 is pulled, and the rotating plate 626 is rotated, so that the rotating plate 626 is placed on the upper end surface of the limit plate 625, so that the wedge block 622 is radially away from the square groove 520, so that the two adjacent eccentric shafts 412 are no longer radially plugged and limited. At this time, the square head 510 can be taken out from the square groove 520 along the axial direction, so that the two adjacent eccentric shafts 412 are separated.

[0037] like Figure 5 As shown, in this embodiment, a slide groove 611 is arranged in the plug-in cavity, and the plug-in component 620 further includes a slider 627 arranged on the wedge block 622 and slidably connected to the slide groove 611. Specifically, when the wedge block 622 moves radially, the slider 627 slides relative to the slide groove 611 to guide the movement of the wedge block 622, and the slider 627 and the combined shell 610 are radially limited, so that the radial movement range of the wedge block 622 is limited, and the square head 510 is prevented from contacting the non-inclined surface of the wedge block 622.

[0038] like Figure 4 As shown, in this embodiment, the square head 510 is provided with a connection hole 1 630 in the radial direction, and the second axial end of the eccentric shaft 412 is provided with a connection hole 2 640 in the radial direction corresponding to the connection hole 1 630, and the radial plug-in structure includes a connection bolt 1 that is inserted through the connection hole 1 630 and the connection hole 2 640, and a locking nut 1 that is threadedly connected to the free end of the connection bolt 1. Specifically, after the square head 510 is inserted into the square groove 520 in the axial direction, the connection hole 1 630 and the connection hole 2 640 are arranged in the radial direction. At this time, the connection bolt 1 penetrates the connection hole 1 630 and the connection hole 2 640, and then the locking nut 1 is threadedly connected to the free end of the connection bolt 1, so as to realize the radial plug-in limit of the two adjacent eccentric shafts 412.

[0039] like Figure 4 As shown, in this embodiment, a fastening shell 413 is provided on the axial first end of the vibration plate 411, and a connecting plate 414 is provided on the axial second end of the vibration plate 411 for plugging and matching with the fastening shell 413 on the axial first end of the adjacent vibration plate 411, and the oscillating member also includes a second connecting bolt for passing through the fastening shell 413 and the connecting plate 414, and a second fastening nut for threading with the free end of the second connecting bolt. Specifically, when it is necessary to expand the overall vibration area of ​​the vibration assembly 400, two adjacent vibration plates 411 are plugged and matched through the fastening shell 413 and the connecting plate 414, and then locked and fixed through the second connecting bolt and the second fastening nut, so as to connect the two adjacent vibration plates 411 into a whole.

[0040] like Figure 4 As shown, in this embodiment, a mounting shell 415 is provided on the axial first end of the vibration plate 411, and a combination plate 416 is provided on the axial second end of the vibration plate 411 for plugging and matching with the mounting shell 415 on the axial first end of the adjacent vibration plate 411, and the oscillating member also includes a connecting bolt 3 for passing through the mounting shell 415 and the combination plate 416, and a fastening nut 3 for threading with the free end of the connecting bolt 3. Specifically, when it is necessary to expand the overall vibration area of ​​the vibration assembly 400, two adjacent vibration plates 411 are plugged and matched through the mounting shell 415 and the combination plate 416, and then locked and fixed by the connecting bolt 3 and the fastening nut 3, so as to connect the two adjacent vibration plates 411 into a whole.

[0041] like Figure 4 As shown, optionally, the fastening shell 413 and the connecting plate 414 are located at the top of the vibration plate 411, and the mounting shell 415 and the combined plate 416 are located at the bottom of the vibration plate 411, so that the two adjacent vibration plates 411 can be fixed in all directions up and down through the joint action of the two, so as to greatly improve the overall strength, rigidity and relative stability of the two adjacent vibration plates 411 after connection, improve the anti-overturning ability of the extended section, realize the overall resonance and same frequency effect of the vibration plate 411, and ensure the consistency of vibration density and flatness of the same working surface.

[0042] like Figure 4 As shown, in this embodiment, the radial cross section of the combined plate 416 is arranged in an I-shaped shape, and the inner wall shape of the mounting shell 415 is adapted to the combined plate 416. Specifically, after the combined plate 416 is inserted into the mounting shell, the I-shaped structure prevents the combined plate 416 from moving up and down in the mounting shell 415, thereby further improving the connection strength of the side portion of the vibration plate 411.

For those skilled in the art, the present invention may have various modifications and variations.
