[0001] This invention relates to the field of concrete vibration, and in particular to a concrete vibration device for construction. Background Technology

[0002] When pouring concrete mixed in a concrete mixer, air bubbles must be removed and the concrete must be compacted to ensure a dense bond, eliminate honeycomb and pitting phenomena, improve its strength, and guarantee the quality of the concrete components.

[0003] Currently, vibrators are mostly used to compact concrete. However, when pouring road surfaces, workers usually need to walk inside the concrete and hold the hose on the vibrator to compact it, which greatly increases the workload of the workers. Summary of the Invention

[0010] Multiple bushings each have a sliding square shaft, and multiple brackets are connected by a square rod frame. A power seat slides on the square rod frame, and a power wheel is installed on the power seat.

[0032] like Figure 1-11 The following is a detailed description of a concrete vibrating device:

[0033] A concrete vibration device includes a drag plate 101, extension plates 102, a support 103, a traction frame 104, and a cross frame 201. The drag plate 101 has an inclined plate at its front end, two extension plates 102 are fixed on the drag plate 101, the traction frame 104 rotates at the front end of the two extension plates 102, the support 103 is fixed on the drag plate 101, the cross frame 201 is connected to the support 103, and multiple vibration mechanisms are connected to the cross frame 201.

[0034] In use, the platform 101 is placed on the concrete pavement, and multiple vibration mechanisms are inserted into the concrete in front of the platform 101. The multiple vibration mechanisms are activated to vibrate the concrete in the vicinity. At the same time, by pulling the traction frame 104, the platform 101 is moved forward, and the multiple vibration mechanisms move forward with the platform 101 in the concrete. After the multiple vibration mechanisms vibrate the concrete, the platform 101 smooths the vibrated concrete pavement, thereby improving the work efficiency of this device when laying concrete pavement. This eliminates the need for manual walking in the concrete to perform vibration work, improving vibration efficiency while reducing manual labor intensity.

[0035] The front end of the trailer plate 101 is equipped with an inclined plate, which enables the trailer plate 101 to move forward more smoothly while ensuring the effect of smoothing the road surface.

[0036] like Figure 1-11 As shown:

[0037] Each of the vibration mechanisms includes a bracket 501, a central seat 502, tension springs I 503, a bushing 504, a central frame 505, a counterweight rod 506, and an outer tube 601. The bracket 501 is connected to the crossbeam 201, the central seat 502 is disposed inside the bracket 501, six tension springs I 503 are evenly disposed between the bracket 501 and the central seat 502, the bushing 504 rotates inside the central seat 502, the central frame 505 is fixed to the lower end of the bushing 504, the counterweight rod 506 is eccentrically disposed on the central frame 505, and the outer tube 601 rotates on the central frame 505.

[0038] During the vibration operation, the outer pipe 601 is inserted into the concrete, the drive shaft sleeve 504 rotates, which in turn drives the central frame 505 to rotate inside the outer pipe 601, and at the same time drives the counterweight rod 506 to rotate eccentrically. The eccentrically rotating counterweight rod 506 will cause the outer pipe 601 to vibrate inside the concrete, thereby forming the vibration of the concrete.

[0039] Meanwhile, by setting six tension springs I 503 between the center seat 502 and the bracket 501, the center seat 502 is located at the center of the bracket 501 when the vibration mechanism is not in operation. When the vibration mechanism is in operation, the center seat 502 can vibrate with the outer tube 601 inside the bracket 501 through the elastic force of the six tension springs I 503, thereby eliminating the vibration of the bracket 501 and preventing the entire device from being affected by vibration.

[0040] Further:

[0041] A sealing ring 603 is fixed at the upper end of the outer tube 601, and the sealing ring 603 is sleeved on the bushing 504.

[0042] By setting the sealing ring 603, concrete is prevented from entering through the gap between the outer tube 601 and the bushing 504 when the outer tube 601 is inserted into the concrete, thus avoiding damage to the vibration mechanism.

[0043] like Figure 1-11 As shown:

[0044] The adjusting screw 507 rotates at the lower end of the central frame 505. The adjusting screw 507 is threadedly connected to the counterweight rod 506. The lower end of the outer tube 601 is threadedly fixedly connected to a semi-circular head 602.

[0045] When it is necessary to adjust the vibration level, the semi-circular head 602 located at the lower end of the outer tube 601 is screwed down, and then the counterweight rod 506 is driven by the screw by rotating the adjusting screw 507, so that the counterweight rod 506 moves within the center frame 505, thereby adjusting the distance between the counterweight rod 506 and the center of the center frame 505. The larger the distance, the larger the eccentricity and the greater the vibration level; conversely, the smaller the distance, the smaller the eccentricity and the smaller the vibration level.

[0046] The semi-circular head 602 is detachably fixed to the lower end of the outer tube 601 by threads, forming a protection for the lower end of the outer tube 601.

[0047] like Figure 1-11 As shown:

[0048] Square shafts 402 slide within multiple bushings 504. Square rods 301 are connected through multiple brackets 501. A power seat 302 slides on the square rod 301. A power wheel is installed on the power seat 302. The power wheel is connected to the multiple square shafts 402. A spring 303 is provided between the square rod 301 and the power seat 302.

[0049] The elastic force of the spring 303 keeps the chain that drives the power wheel and multiple square shafts 402 in a taut state, thus adapting to the vibration of the multiple square shafts 402 in any direction during use.

[0050] When in use, start the first motor installed on the power base 302 to drive the power wheel, which can simultaneously drive the rotation of multiple square shafts 402.

[0051] Further:

[0052] A vertical screw 202 is rotatably mounted on the bracket 103, and the vertical screw 202 is threadedly connected to the horizontal frame 201.

[0053] By rotating the vertical screw 202, the vertical screw 202 can drive the horizontal frame 201 to rise and fall on the support 103, thereby driving multiple vibration mechanisms to rise and fall relative to the drag plate 101, thus adjusting the horizontal height of multiple vibration mechanisms so that the device can adapt to the vibration of concrete at different depths.

[0054] like Figure 1-11 As shown:

[0055] The support frame 204 is fixedly connected to the bracket 103. A horizontal shaft frame 203 is connected to the support frame 204. Multiple auxiliary plates 401 are rotatably mounted on the horizontal shaft frame 203. The upper ends of multiple square shafts 402 are all connected to the multiple auxiliary plates 401.

[0056] The support of the auxiliary plate 401 for the square shaft 402 ensures the chain drive between the square shaft 402 and the drive wheel. Furthermore, the telescopic sliding between the square shaft 402 and the bushing 504 ensures that the drive wheel can still drive multiple square shafts 402 when the device adjusts the horizontal height of multiple vibration mechanisms through the vertical screw 202.

[0057] Further:

[0058] Six tension springs II 403 are evenly provided between each square shaft 402 and the corresponding auxiliary plate 401.

[0059] The elastic force of the six tension springs II 403 ensures that the upper end of the square shaft 402 is located at the center of the auxiliary plate 401. Then, when the vibration mechanism is running, the square shaft 402 can vibrate in the auxiliary plate 401 along with the outer tube 601 through the elastic force of the six tension springs I 503, thereby eliminating the vibration of the bracket 501 and preventing the entire device from being affected by vibration.

[0060] Further:

[0061] A control screw 205 is rotatably mounted on the support frame 204, and the control screw 205 is threadedly connected to the horizontal shaft frame 203.

[0062] By rotating the control screw 205, the threaded drive horizontal shaft 203 moves back and forth on the support frame 204. Then, the horizontal shaft 203 drives multiple auxiliary plates 401 to move back and forth. Simultaneously, the rotation of the auxiliary plates 401 and the horizontal shaft 203 causes the bracket 501 to rotate on the horizontal frame 201, thereby adjusting the angle between the outer pipe 601 and the drag plate 101. This allows the device to ensure that the entire outer pipe 601 is completely submerged in the concrete when vibrating concrete at different depths, thus guaranteeing the vibration effect.

[0063] Further:

[0064] The lower end of the bracket 103 is provided with a counterweight.

[0065] By setting up a counterweight, the device will not tilt when it is pulled by the traction frame 104, thereby ensuring the leveling effect of the towing plate 101.
