Description

Technical Field

[0001] The present invention relates to the technical field of precast concrete components, and particularly relates to a concrete vibrating device for engineering construction. Background Art

[0002] Precast concrete components refer to concrete products processed and produced in factories in a standardized and mechanized manner. During the production process of precast concrete components, it is necessary to vibrate the concrete poured inside the precast mold to remove the air bubbles inside the concrete, so that the concrete is densely combined, thereby ensuring the quality of the concrete components.

[0003] The existing vibrating method for precast concrete components usually uses a vibrating rod held manually by workers for vibrating work. During this period, the position needs to be changed many times, which is time-consuming and laborious. Moreover, when the vibrating work is completed, when the vibrating rod is directly pulled out manually, there may be problems such as air entering to generate bubbles and the upper end surface of the concrete being uneven. At the same time, it is also necessary for workers to level the upper end surface of the concrete, and both the vibrating efficiency and the vibrating quality need to be improved.

[0031] Refer to Figure 2 and Figure 8 Figure 8 , the alignment mechanism 3 includes an arc-shaped installation groove 31 formed at the upper end of the cover plate of the support frame 1. A rectangular installation groove 32 is formed at the lower end of the cover plate of the support frame 1. The arc-shaped installation groove 31 and the rectangular installation groove 32 are arranged in an up-and-down corresponding manner.

[0035] See also Figure 2-Figure 4 The lifting and vibrating part 64 also includes a circular plate 647 rotatably installed in the installation barrel 63, a circular installation groove 648 is opened in the middle of the upper end of the circular plate 647, and a fan-shaped avoidance groove 649 connected to the circular installation groove 648 is also opened at the upper end of the circular plate 647. The lower end of the transmission screw 645 is rotatably connected to the inner wall of the circular installation groove 648, and a limiting slide plate 650 is installed on the outer wall of the transmission screw 645 corresponding to the position of the fan-shaped avoidance groove 649. The limiting slide plate 650 is slidably connected in the fan-shaped avoidance groove 649, and the limiting slide plate 650 is always located in the fan-shaped avoidance groove 649. A plurality of vibrating rods 651 evenly distributed in a circle are installed at the lower end of the circular plate 647, and the plurality of vibrating rods 651 all slide through the circular slide plate 83.

[0036] See also Figure 1-Figure 3And Figure 5 The rotation limiting mechanism 7 includes an annular gear 71 installed in the middle of the upper end of the circular plate 647. A forward and reverse motor two 72 is installed at the upper end of the installation barrel 63 through a motor base. The output shaft of the forward and reverse motor two 72 rotates through the installation barrel 63 and is fixedly connected with an incomplete gear 73. The incomplete gear 73 is intermittently engaged with the annular gear 71. A circular positioning hole 74 is formed in the circular plate 647.

[0037] It should be noted that the positioning plug 76 is initially located in the circular positioning hole 74. Under the limiting action of the positioning plug 76, the support barrel 641 is controlled to rotate forward by the forward and reverse motor one 642. The support barrel 641 drives the hollow lead screw one 643 to move downward through screw transmission until it cannot continue to move downward under the limiting action of the annular limiting plate 646. At this time, the support barrel 641 drives the hollow lead screw one 643 to rotate synchronously. Then, the hollow lead screw one 643 drives the hollow lead screw two 644 to move downward through screw transmission until it cannot continue to move downward under the limiting action of the annular limiting plate 646. At this time, the hollow lead screw one 643 continues to drive the hollow lead screw two 644 to rotate synchronously. Then, the hollow lead screw two 644 drives the transmission lead screw 645 to move downward through screw transmission until it cannot continue to move downward under the limiting action of the annular limiting plate 646. During this period, the transmission lead screw 645 drives a plurality of vibrating rods 651 to move downward synchronously through the circular plate 647 until the plurality of vibrating rods 651 are all inserted into the lower side position of the concrete poured in the precast mold. The circular plate 647 drives the front and rear support slides 62 to slide adaptively along the corresponding C-shaped support legs 5 through the installation barrel 63.

[0038] After the multiple vibrating rods 651 are inserted into the lower side of the concrete poured by the prefabricated mold, the multiple vibrating rods 651 are controlled to vibrate the concrete, and then the electric telescopic rod 1 75 is controlled to drive the positioning rod 76 to withdraw from the circular positioning hole 74, and then the incomplete gear 73 and the ring gear 71 are controlled by the forward and reverse motor 2 72 to drive the circular plate 647 to rotate forward and reverse 90 degrees. The circular plate 647 will drive the multiple vibrating rods 651 to rotate forward and reverse 90 degrees, thereby achieving the effect of uniformly vibrating the concrete. During this period, the limiting slide plate 650 will move along the fan-shaped avoidance groove 649 Adaptive sliding compensation is performed inside, and when multiple vibrating rods 651 rotate forward and reverse 90 degrees, the circular slide plate 83 will be driven to follow the forward and reverse rotation of 90 degrees. The multi-stage lifting and vibrating mechanism 6 and the rotation limiting mechanism 7 cooperate to control the multiple vibrating rods 651 to be lifted and lowered step by step to insert or withdraw from the concrete. The multiple vibrating rods 651 can also be controlled to rotate forward and reverse 90 degrees, thereby achieving the effect of multiple vibrating rods 651 jointly vibrating the concrete in the precast mold evenly, without the need for manual hand-held vibrating rods 651 to change the vibration position multiple times, effectively improving the efficiency and uniformity of the vibration of the concrete in the precast mold.

[0039] See also Figure 3 and Figure 7 The auxiliary vibration part 43 includes a hollow barrel 431 installed on the upper end of the support disc 423, and a forward and reverse motor 432 is installed on the lower end of the support disc 423 through a motor seat. A rectangular avoidance opening 433 is opened at the position of the forward and reverse motor 432 corresponding to the bottom plate of the support frame 1, and the output shaft of the forward and reverse motor 432 is fixedly connected to a rotating shaft 434, and a plurality of cams 435 are evenly installed on the rotating shaft 434. Vibration groups are provided at positions corresponding to the plurality of cams 435 on the outer wall of the hollow barrel 431, and the vibration group includes a plurality of circumferentially evenly distributed knocking rods 436 that slide through the outer wall of the hollow barrel 431, and a mounting plate 437 is fixedly sleeved at one end of the plurality of knocking rods 436 on the outer side of the hollow barrel 431, and the mounting plate 437 is connected to the outer wall of the hollow barrel 431 through a compression spring, and the plurality of knocking rods 436 are located at one end of the inner side of the hollow barrel 431 and are movably contacted with the cam 435.

[0040] See also Figure 1 , Figure 3 , Figure 6 and Fig. 9The smoothing and beating part 84 includes an arc-shaped mounting hole 841 symmetrically opened on the outer wall of the annular plate 82, and an arc-shaped slide seat 842 is slidably mounted in the front and rear arc-shaped mounting holes 841.

Two cams 1 845 are symmetrically mounted on the transmission shaft 843, and the two cams 1 845 are both rollingly contacted with the circular slide plate 83 On the transmission shaft 843, an arc-shaped connecting rod 846 is symmetrically rotatably sleeved, and the two ends of the arc-shaped connecting rod 846 are respectively movably sleeved on the corresponding vibrating rod 651, and an arc-shaped slide plate 847 is installed at the lower end of the arc-shaped connecting rod 846, and the two ends of the arc-shaped slide plate 847 are respectively movably sleeved on the corresponding vibrating rod 651, and the outer wall of the arc-shaped slide plate 847 is movably fitted on the inner wall of the annular plate 82, and the positions of multiple vibrating rods 651 at the lower ends of the two arc-shaped slide plates 847 are connected to the circular slide plate 83 through tension springs, and an annular trowel plate 848 is installed at the lower end of the circular slide plate 83, and multiple vibrating rods 651 all slide through the annular trowel plate 848.

[0041] When the support disc 423 and the cover plate of the support frame 1 are fitted together, the support disc 423 will drive the hollow barrel 431 to be inserted into the circular inner cavity in the middle of the precast mold. When the multiple vibrating rods 651 are controlled to vibrate the concrete, the rotating shaft 434 is controlled by the forward and reverse motor 5 432 to drive the multiple cams 435 to rotate. Under the action of the compression spring, the multiple cams 435 respectively push the corresponding multiple knocking rods 436 to reciprocate and knock the circular inner wall in the middle of the precast mold, thereby realizing the auxiliary vibration of the concrete in the precast mold to remove bubbles. Effect: When multiple vibrating rods 651 have completed uniformly vibrating the concrete by rotating forward and reverse 90 degrees, the forward and reverse motor 72 is controlled to stop working. It should be noted that the lower end surface of the annular trowel plate 848 is initially higher than the upper end surface of the concrete, and while the circular plate 647 follows the multiple vibrating rods 651 to rotate forward and reverse 90 degrees, the multiple vibrating rods 651 will respectively drive the corresponding arc-shaped connecting rods 846 to synchronously rotate forward and reverse 90 degrees. During this period, the transmission shaft 843 will drive the two arc-shaped slides 842 to perform adaptive sliding compensation along the corresponding arc-shaped mounting holes 841.

[0042] Next, control the electric telescopic rod 1-75 to drive the positioning plug rod 76 to insert into the circular positioning hole 74 again to restore the original position. Under the limiting action of the positioning plug rod 76, control the support barrel 641 to rotate in the reverse direction through the forward and reverse motor 1-642. The transmission lead screw 645 moves upward through screw transmission and retracts into the hollow lead screw 2-644. The hollow lead screw 2-644 moves upward through screw transmission and retracts into the hollow lead screw 1-643. The hollow lead screw 1-643 moves upward through screw transmission and retracts into the support barrel 641 to restore the original position. During this period, the transmission lead screw 645 drives a plurality of vibrating rods 651 to move upward synchronously through the circular plate 647 until the plurality of vibrating rods 651 completely withdraw from the concrete poured in the precast mold, and the circular plate 647 drives the front and rear support sliding plates 62 to respectively perform adaptive sliding compensation along the corresponding C-shaped support legs 5 through the mounting barrel 63.

[0043] During the step-by-step upward movement of the multiple vibrating rods 651, the transmission shaft 843 is controlled by the forward and reverse motor 3 844 to drive the two cams 1 845 to rotate. Under the action of the tension spring, the circular slide 83 will drive the annular trowel plate 848 to reciprocate up and down, thereby compacting the upper end surface of the concrete. When the multiple vibrating rods 651 completely exit the concrete poured by the precast mold, the incomplete gear 73 and the annular gear 71 are controlled by the forward and reverse motor 2 72 again to drive the circular plate 647 forward and reverse 90 degrees. The circular plate 647 will drive the multiple vibrating rods 651 to reverse 90 degrees forward and reverse. The multiple vibrating rods 651 pass through the circular slide 8 3 drives the annular trowel plate 848 to smooth the upper end surface of the concrete. When the smoothing work on the upper end surface of the concrete is completed, the transmission shaft 843 is controlled by the forward and reverse motor 3 844 to drive the two cams 1 845 to rotate until, under the action of the tension spring, the circular plate 647 drives the annular trowel plate 848 to move upward and return to the annular plate 82, so that the lower end surface of the annular trowel plate 848 is higher than the upper end surface of the prefabricated mold. Finally, the forward and reverse motor 421 controls the ball screw 1 422 to rotate in the opposite direction, and the ball screw 1 422 drives the support disc 423 to move downward to a suitable position. At this time, the support disc 423 drives the hollow barrel 431 moves downward to restore the original position, and then controls the electric telescopic rod 2 37 to drive the rack 38 and the passive gear 33 to drive the ball screw 2 34 to rotate. The ball screw 2 34 drives the arc limit plate 35 to move downward and return to the arc installation groove 31. The precast mold can be taken out from left to right by the external unloading device. Repeat the above operation to repeatedly vibrate the concrete in the precast mold. The positioning mechanism 3, the auxiliary vibration mechanism 4, the multi-stage lifting and vibrating mechanism 6, the rotation limit mechanism 7 and the smoothing and beating mechanism 8 can cooperate to place the precast mold for auxiliary positioning. The multi-stage lifting and multiple vibrating rods 651 are used to rotate 90 degrees forward and reverse together. The vibration method can achieve the effect of multiple vibrating rods 651 jointly vibrating the concrete in the precast mold evenly, and can control multiple knocking rods 436 to reciprocately knock and vibrate the middle inner wall of the precast mold, further enhancing the vibration mixing and degassing effect of the concrete in the precast mold. In addition, after the vibration work is completed, multiple vibrating rods 651 are withdrawn step by step, and the upper end surface of the concrete is reciprocated to compact, so as to avoid the problem of air entering the concrete to produce bubbles and uneven upper end surface of the concrete when the vibrating rod 651 is directly pulled out, and the upper end surface of the concrete can be automatically smoothed, which effectively improves the quality and efficiency of vibration.
