Description

Technical Field

[0001] This utility model relates to the field of concrete preparation, and in particular to a concrete vibration auxiliary device. Background Technology

[0002] In concrete construction, vibration is a crucial step in ensuring concrete density and reducing air bubbles and honeycomb-like pitting. Traditional vibration mainly relies on manual operation with handheld vibrators, which suffers from high labor intensity, poor vibration uniformity, and low efficiency. Although some mechanized vibration equipment, such as track-mounted vibrators or robotic arm-assisted devices, exists, these devices are often complex in structure, expensive, and poorly adaptable to small-area or complex formwork construction. Furthermore, the walking mechanisms of existing equipment often use gear and rack or chain drives, which are susceptible to jamming due to concrete splashes, resulting in high maintenance costs.

[0003] Therefore, a concrete vibration auxiliary device is being developed to address the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] A concrete vibration auxiliary device, such as Figures 1-3 As shown, the system includes an installation track 1, a sliding frame 2 slidably connected within the installation track 1, multiple pulleys 3 rotatably connected to the sliding frame 2, the pulleys 3 contacting the inner bottom surface of the installation track 1, two symmetrical installation frames 4 on the sliding frame 2, a drive motor 5 mounted on the installation frame 4, a drive wheel 6 connected to the output shaft of the drive motor 5, pressure plates 7 slidably connected to both the front and rear sides of the installation track 1, the pressure plates 7 being able to contact the adjacent drive wheels 6, a first threaded component 8 threadedly connected to the pressure plate 7, the first threaded component 8 being rotatably connected to the installation track 1, a second threaded component 9 threadedly connected to the sliding frame 2, the second threaded component 9 having a spherical structure on its inner side for pressing and limiting the vibrator.

[0017] It should be noted that when the device is working, the installation track 1 is first laid horizontally on the concrete pouring template or the top of the pre-set cement bearing. The track is made of rigid material, and the inner bottom surface is precision machined to form a sliding plane with a low coefficient of friction. The sliding frame 2 forms rolling contact with the track through the pulley 3. The pulley 3 adopts an eccentric shaft design, which can compensate for the flatness error of the track installation surface by finely adjusting the height of the wheel axle, ensuring that the sliding frame 2 can still maintain stable movement under uneven conditions within 3mm. The double-sided clamping plates 7 of the track need to be pre-tightened by the first threaded part 8 during the initial installation. When the threaded part is rotated, it pushes the clamping plate 7 to move inward, so that it forms an elastic contact gap of 0.5-1.2mm with the drive wheel 6. This design ensures driving friction and avoids overload jamming. After the two symmetrically arranged drive motors 5 are powered on, the output shaft drives the 80mm diameter polyurethane drive wheel 6 to rotate at high speed. Since the clamping plate 7 has been pre-tightened with threads to apply radial pressure, rolling friction is generated between the drive wheel 6 and the clamping plate 7 when the drive wheel 6 rotates. This friction reacts on the sliding frame 2 to form a propulsive force. According to Coulomb's law of friction, when the coefficient of friction is 0.4, a single drive wheel 6 can generate a driving force of about 120N. In the dual-drive mode, the total thrust reaches 240N, which is sufficient to overcome the maximum axial resistance of 150N generated by the vibrator when it is inserted into the concrete. The vibrator is clamped and positioned by the spherical structure of the second threaded part 9. The device travel speed is controlled within the range of 0.3-1.2m / min by the PWM speed regulation module, which corresponds to the standard time of 20-30 seconds per point vibration required by the concrete vibration specification.

[0018] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
