Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction equipment, and particularly to a concrete vibrating device. Background Art

[0002] During the concrete construction process, after the concrete is poured, concrete vibration is required. This is because during the concrete mixing process, due to the viscosity of the cement paste and the influence of factors such as the shape and particle size of the aggregates, air bubbles and gaps are easily formed inside the concrete. If these air 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 air bubbles and pores, eliminate phenomena such as honeycombing and pockmarks on the concrete, make the concrete densely combined, improve the strength of the concrete, and ensure the pouring quality.

[0003] Currently, a vibrating screed is usually used for vibrating operations. In actual applications, with the change of the application environment, the vibrating area of the vibrating screed also needs to change accordingly. Therefore, as disclosed in the Chinese utility model patent CN221255121U, an adjustable concrete vibrating screed is provided, which includes a cover plate. A support plate and a first spring are fixedly connected to the bottom of the cover plate. A support pad is connected to the bottom of the support plate, and a square pad is connected to the bottom of the first spring. The bottom of the square pad and the support pad are fixedly connected to the main scale plate. A secondary scale plate is slidably connected inside the main scale plate. A motor is connected to the middle of the top of the cover plate, and a protective frame and a baffle are fixedly connected to the edge of the cover plate. A support rod is fixedly connected to the top of the baffle, and a shock-absorbing cylinder is connected to the top of the support rod. A handle is connected to one side of the shock-absorbing cylinder. Through the setting of the shock-absorbing cylinder and the second spring in the utility model, the vibration wave emitted by the vibration of the motor can be slowed down. By adjusting the secondary scale plate, the working area of the concrete vibrating screed is increased, the working range of the concrete vibrating scale plate is widened, and the working efficiency of the operator is improved.

[0004] However, in the above adjustable concrete vibrating screed, although the working area can be adjusted by adjusting the secondary scale plate, after the secondary scale plate is extended to increase the working area, since the main scale plate and the secondary scale plate are of a split structure, and the vibration wave emitted by the vibration of the motor is first transmitted to the main scale plate and then to the secondary scale plate, there are differences in the vibrating effects between the main scale plate and the secondary scale plate. Furthermore, during the vibrating operation, the consistency of the compactness and flatness of the same working surface cannot be guaranteed, and the concrete forming quality is poor. Summary of the Utility Model

[0005] The utility model provides a concrete vibrating device to solve the technical problem that the existing vibrating equipment cannot guarantee the consistency of the compactness and flatness of the same working surface and has poor concrete forming quality after increasing the working area.

[0006] According to one aspect of the present utility model, there is provided a concrete vibrating device, including an installation platform, a driving and rotating assembly, an operating handle, and a vibrating assembly. The driving and rotating assembly and the operating handle are arranged on the installation platform. The vibrating assembly includes a plurality of vibrating members. Each vibrating member includes a vibrating plate for contacting the concrete surface for vibrating operation and an eccentric shaft rotatably arranged on the vibrating plate for generating vibration waves after rotation and transmitting them to the vibrating plate. The vibrating plate in one of the vibrating members is arranged on the installation platform, and the eccentric shaft in the vibrating member is connected to the output end of the driving and rotating assembly. Adjacent two vibrating plates are detachably connected, and axial insertion structures for axially inserting and mating with each other are respectively arranged on adjacent two eccentric shafts to perform angular and radial limiting on the adjacent two eccentric shafts. The vibrating member is provided with a radial insertion structure for radially inserting and mating with the axial insertion structure to perform axial, radial, and angular limiting on the adjacent two eccentric shafts.

[0007] As a further improvement of the above technical solution:

[0009] Further, a first insertion groove is radially opened on the square head, a second insertion groove communicating with the square groove is radially opened at the axial second end of the eccentric shaft. The radial insertion structure includes a combined shell arranged on the second insertion groove and an insertion member passing through the combined shell for sequentially inserting into the first insertion groove radially. The combined shell is radially provided with an insertion cavity communicating with the square groove.

[0010] Further, the insertion member includes a pull rod radially passing through the combined shell, a wedge block fixedly connected to the extending end of the pull rod, a knob fixedly connected to the extending end of the pull rod for abutting and limiting against the outer wall of the combined shell, and a compression spring sleeved on the pull rod and arranged in the insertion cavity.

[0012] Further, a sliding groove is arranged in the insertion groove, and the insertion member further includes a sliding block arranged on the wedge block and slidably connected to the sliding groove.

[0013] Further, a first connecting hole is radially penetrated through the square head, a second connecting hole corresponding to the first connecting hole is radially penetrated through the axial second end of the eccentric shaft.

[0014] Further, a fastening shell is provided at the first axial end of the vibrating plate, and a connecting plate for plugging and mating with the fastening shell at the first axial end of an adjacent vibrating plate is provided at the second axial end of the vibrating plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0029] Such as Figures 1-4As shown in the figure, the concrete vibrating device of this embodiment includes an installation platform 100, a rotation driving assembly 200, an operating handle 300, and a vibrating assembly 400. The rotation driving assembly 200 and the operating handle 300 are arranged on the installation platform 100. The vibrating assembly 400 includes a plurality of vibrating members 410. Each vibrating member 410 includes a vibrating plate 411 for contacting the concrete surface to perform vibrating operations and an eccentric shaft 412 rotatably arranged on the vibrating plate 411 for generating vibration waves after rotation and transmitting them to the vibrating plate 411. The vibrating plate 411 of one of the vibrating members 410 is arranged on the installation platform 100, and the eccentric shaft 412 of the vibrating member 410 is connected to the output end of the rotation driving assembly 200. Adjacent vibrating plates 411 are detachably connected, and axial insertion structures for axially inserting and mating with each other are respectively arranged on adjacent eccentric shafts 412 to perform angular and radial limits on the adjacent eccentric shafts 412. The vibrating member 410 is provided with a radial insertion structure arranged on the eccentric shaft 412 for radially inserting and mating with the axial insertion structure to perform axial, radial, and angular limits on the adjacent eccentric shafts 412.

[0030] As Figure 1 and Figure 2 shown, optionally, a bearing seat is arranged on the vibrating plate 411, and the eccentric shaft 412 is rotatably arranged on the bearing seat. Optionally, the bearing seat is arranged on the vibrating plate 411 through a mounting plate. Optionally, the eccentric shaft 412 includes a shaft main body and an eccentric wheel fixedly sleeved on the shaft main body. The shaft main body is connected to the rotation driving assembly 200. When the rotation driving assembly 200 drives the shaft main body to rotate, the eccentric wheel rotates synchronously. Due to its uneven mass distribution, a continuously changing unbalanced torque will be generated. This unbalanced torque will generate vibration waves that cause reciprocating acceleration and deceleration movements. After being transmitted to the vibrating plate 411, the vibrating plate 411 is caused to vibrate, and then transmitted to the concrete surface through the vibrating plate 411. During the vibration process, the aggregate particles inside the concrete can flow better and rearrange, reducing voids and making the concrete mixture more compact, thereby completing the leveling treatment of the concrete. Optionally, the rotation driving assembly 200 includes a driving motor. A first pulley is fixedly sleeved on the output shaft of the driving motor, and a second pulley is fixedly sleeved on the shaft main body. The first pulley and the second pulley are connected by a belt for transmission.

[0031] As Figures 1-4As shown in the figure, specifically, for the concrete vibrating device of the present utility model, a driving and rotating assembly 200, an operating handle 300, and a vibrating assembly 400 are installed through an installation platform 100. An operator controls the vibrating operation direction of the vibrating device through the operating handle 300. During the vibrating operation, the eccentric shaft 412 is driven to rotate by the driving and rotating assembly 200, so that the eccentric shaft 412 generates vibration waves and transmits them to the vibrating plate 411, and then the vibrating plate 411 contacts the concrete surface to perform the vibrating operation; when it is necessary to expand the vibrating and leveling range, the number of vibrating members 410 can be increased. When two adjacent vibrating plates 411 are connected, the adjacent eccentric wheels are axially inserted into each other through an axial insertion structure, so as to perform angular and radial limiting on the adjacent two eccentric shafts 412, and then the radial insertion structure is in radial insertion cooperation with the axial insertion structure to perform axial, radial, and angular limiting on the adjacent two eccentric shafts 412, so that the adjacent two eccentric shafts 412 are connected to form a whole. When the driving and rotating assembly 200 drives one of the eccentric shafts 412 to rotate, the other eccentric shafts 412 rotate synchronously, and synchronously transmit vibration waves to the corresponding vibrating plates 411, ensuring the overall vibration effect. Moreover, after axial insertion, radial insertion can be quickly carried out. The connection and positioning of the two eccentric shafts 412 are simple, the disassembly and assembly are convenient, the risk of incorrect installation is reduced, and the maintenance and inspection of the device are made easier, which is more beneficial for the construction site where the device needs to be frequently disassembled and assembled for corresponding adjustments. In this solution, the adjacent two eccentric shafts 412 are connected to form a whole through the axial insertion structure and the radial insertion structure, ensuring the overall vibration effect. Compared with the prior art, it can ensure the consistency of the vibrating compactness and flatness of the same working surface, improve the concrete forming quality, and has strong practicability, being suitable for wide promotion and application.

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

[0033] As Figure 4 shown, in this embodiment, the axial insertion structure includes a square head 510 disposed at the axial first end of the eccentric shaft 412 and a square groove 520 opened at the axial second end of the eccentric shaft 412 for axially inserting and cooperating with the square head 510 at the axial first end of the adjacent eccentric shaft 412. Specifically, when two adjacent vibrating plates 411 are connected, the square head 510 is axially inserted into the square groove 520, so as to perform radial and angular limiting on the adjacent two eccentric shafts 412 through the axial insertion cooperation of the square head 510 and the square groove 520.

[0034] As Figure 4As shown, in this embodiment, a first insertion slot is radially formed on the square head 510. A second insertion slot communicating with the square slot 520 is radially formed on the second axial end of the eccentric shaft 412. The radial insertion structure includes a combined housing 610 disposed on the second insertion slot and an insertion member 620 passing through the combined housing 610 for sequentially inserting into the first insertion slot along the radial direction. The combined housing 610 is radially provided with an insertion cavity communicating with the square slot 520. Specifically, when the square head 510 and the square slot 520 are axially inserted and matched, the first insertion slot and the second insertion slot are correspondingly arranged in the radial direction. At this time, the insertion member 620 radially passes through the combined housing 610 on the second insertion slot and inserts into the first insertion slot, so as to axially limit, radially limit and angularly limit two adjacent eccentric shafts 412, that is, two adjacent eccentric shafts 412 are connected into a whole through the cooperation of the axial insertion structure and the radial insertion structure, and the axial insertion structure can reduce the insertion difficulty of the radial insertion structure, so as to more quickly realize disassembly and installation.

[0035] As Figure 5 shown, in this embodiment, the insertion member 620 includes a pull rod 621 radially passing through the combined housing 610, a wedge block 622 fixedly connected to the extending end of the pull rod 621, a knob 623 fixedly connected to the protruding end of the pull rod 621 for abutting and limiting against the outer wall of the combined housing 610, and a compression spring 624 sleeved on the pull rod 621 and disposed in the insertion cavity. Specifically, during the process of inserting the square head 510 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 insertion cavity and compresses the compression spring 624. After the square head 510 is inserted in place, the first insertion slot and the second insertion slot are correspondingly arranged. At this time, under the action of the compression spring 624, the wedge block 622 radially inserts into the first insertion slot to limit two adjacent eccentric shafts 412. It should be understood that the inclined surface of the wedge block 622 faces the square head 510. It should be understood that through the combined action of the square head 510, the square slot 520, the wedge block 622 and the compression spring 624, while realizing axial insertion and matching, radial insertion and matching is also realized, greatly increasing the installation speed.

[0036] As Figure 5As shown, in this embodiment, the plug-in member 620 further includes a limiting plate 625 disposed on the combined housing 610, and a rotating plate 626 that is rotatably sleeved on the protruding end of the pull rod 621 and is used to radially abut and limit against the limiting plate 625 to radially move the wedge block 622 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 limiting plate 625, causing the wedge block 622 to radially move away from the square groove 520, thereby no longer radially plugging and limiting the two adjacent eccentric shafts 412. At this time, the square head 510 can be axially removed from the square groove 520, separating the two adjacent eccentric shafts 412.

[0037] As Figure 5 shown, in this embodiment, a sliding groove 611 is provided in the plug-in cavity, and the plug-in member 620 further includes a slider 627 disposed on the wedge block 622 and slidably connected to the sliding groove 611. Specifically, when the wedge block 622 moves radially, the slider 627 slides relative to the sliding groove 611 to guide the movement of the wedge block 622 and radially limit the wedge block 622 through the slider 627 and the combined housing 610, restricting the radial movement range of the wedge block 622 and preventing the non-inclined surface of the square head 510 from contacting the surface of the wedge block 622.

[0038] As Figure 4 shown, in this embodiment, a first connection hole 630 is radially penetrated through the square head 510, and a second connection hole 640 corresponding to the first connection hole 630 is radially penetrated through the second axial end of the eccentric shaft 412. The radial plug-in structure includes a first connection bolt passing through the first connection hole 630 and the second connection hole 640 and a first locking nut threadedly connected to the free end of the first connection bolt. Specifically, after the square head 510 is axially inserted into the square groove 520, the first connection hole 630 and the second connection hole 640 are radially corresponding. At this time, the first connection bolt passes through the first connection hole 630 and the second connection hole 640, and then the first locking nut is threadedly connected to the free end of the first connection bolt to realize the radial plug-in limit of the two adjacent eccentric shafts 412.

[0039] As Figure 4 shown, in this embodiment, a fastening housing 413 is provided at the first axial end of the vibrating plate 411, and a connecting plate 414 for plugging and mating with the fastening housing 413 at the first axial end of the adjacent vibrating plate 411 is provided at the second axial end of the vibrating plate 411. The oscillating member further includes a second connection bolt for passing through the fastening housing 413 and the connecting plate 414 and a second fastening nut for threadedly connecting to the free end of the second connection bolt. Specifically, when it is necessary to expand the overall vibrating and leveling area of the vibrating assembly 400, two adjacent vibrating plates 411 are plugged and mated through the fastening housing 413 and the connecting plate 414, and then locked and fixed through the second connection bolt and the second fastening nut to connect the two adjacent vibrating plates 411 into a whole.

[0040] As Figure 4 shown, in this embodiment, an installation shell 415 is provided at the first axial end of the vibrating plate 411, and a combined plate 416 for plugging and mating with the installation shell 415 at the first axial end of an adjacent vibrating plate 411 is provided at the second axial end of the vibrating plate 411. The oscillating member further includes a third connecting bolt for passing through the installation shell 415 and the combined plate 416 and a third fastening nut for threadedly connecting with the free end of the third connecting bolt. Specifically, when it is necessary to expand the overall vibrating and leveling area of the vibrating and compacting assembly 400, two adjacent vibrating plates 411 are plugged and mated through the installation shell 415 and the combined plate 416, and then locked and fixed through the third connecting bolt and the third fastening nut, so as to connect the two adjacent vibrating plates 411 into a whole.

[0041] As Figure 4 shown, optionally, the fastening shell 413 and the connecting plate 414 are located at the top of the vibrating plate 411, and the installation shell 415 and the combined plate 416 are located at the bottom of the vibrating plate 411, so as to realize the all-round upper and lower limit fixing of two adjacent vibrating plates 411 through their common action, greatly improving the overall strength, stiffness and relative stability of the two adjacent vibrating plates 411 after connection, improving the anti-overturning ability of the extended section, enabling the overall resonance and same-frequency effect of the vibrating plate 411, and ensuring the consistency of the compaction density and flatness of the same working surface.

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

[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
