Technical Field

[0001] The invention belongs to the technical field of prefabricated components for buildings, and relates to a trowel plate structure and a trowel machine for producing prefabricated components. Background Art

[0002] In the manufacturing process of precast concrete piles, concrete, sand and gravel and other raw materials are mixed by a mixer and sent to a feeding truck, which feeds the materials to a distribution truck, and then the distribution truck distributes the materials to a pile mold composed of multiple pile molds. Since the distribution truck itself does not have the leveling and sorting functions, the operator is required to manually level and sort the materials, but manual operation is difficult to ensure the leveling quality. Therefore, a scraping plate is provided on the distribution truck or the pile mold. Although the problem of concrete leveling is solved, it is difficult to level concrete precast piles of different cross-sectional sizes due to the fixed height of the scraping plate on the distribution truck or the pile mold. In addition, there will be a transition area of ​​variable cross-section in the pile mold of variable cross-section, and the leveling operation of this area will still need to be performed manually separately.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1-Figure 4 As shown, a trowel plate structure for prefabricated part production includes a trowel plate, wherein the trowel plate includes a base plate 1, and an end plate 2 is respectively provided at both ends of the base plate 1, and the end plate 2 and the base plate 1 are connected by an inclined plate 3, wherein the lower surface of the base plate 1 protrudes from the lower surface of the end plate 2, and the width of the end plate 2 is greater than the width of the base plate 1.

[0027] Combination Figure 5 As shown, this application is for Figure 5 The special-shaped pile (or variable-section pile) shown in the figure is smoothed, wherein the bottom plate 1 protrudes downward, corresponding to Figure 5 The a part in the figure is smoothed, the inclined plate 3 is smoothed corresponding to the b part, and the end plate 2 is smoothed corresponding to the c part. It should be noted that Figure 5 The special-shaped pile shown is placed in the mold cavity during the production process, and the bottom plate 1, the inclined plate 3 and the end plate 2 are also working in the mold and the mold cavity, and the smoothing operation is performed by reciprocating motion of the front of the trowel plate driven by a driver or manually.

[0028] Those skilled in the art should know that the inclination setting of the inclined plate 3 should be consistent with Figure 5 The b part in the figure is consistent, and those skilled in the art can adjust the inclination of the inclined plate 3 according to different special-shaped piles, and this adjustment belongs to the conventional means. That is, when the inclined plate 3 corresponds to the b part, the inclined plate 3 can be moved horizontally to smooth the b part.

[0029] In a preferred embodiment, the bottom surface and two side surfaces of the inclined plate 3 are inclined surfaces, that is, the bottom plate 1 and the end plate 2 are connected through the inclined surface of the inclined plate 3, and the upper surfaces of the bottom plate 1, the end plate 2 and the inclined plate 3 are flush, thereby forming a whole trowel plate.

[0030] As a preferred solution, Figure 1As shown, the present application also includes a support frame 4, which is fixedly connected to the trowel machine as a fixed part and will not be described here. A lifting mechanism 5 is provided on the support frame 4, one end of the lifting mechanism 5 is fixedly connected to the support frame 4, and the other end is fixedly connected to the trowel plate. The lifting mechanism 5 can reciprocate in the vertical direction to drive the trowel plate to move up and down. The lifting mechanism 5 moves up and down to allow the bottom plate 1 to contact the trowel part, thereby facilitating the trowel work.

[0031] A connecting block 15 is fixedly connected to the supporting frame 4 for easy connection with the trowel machine.

[0032] Specifically, the lifting mechanism 5 includes a cylinder 6, one end of which is fixedly connected to the support frame 4, and the other end of the cylinder 6 is fixedly connected to the upper surface of the trowel plate through the connecting frame 7. The cylinder drives the connecting frame 7 to rise and fall, thereby driving the trowel plate to rise and fall, so that the trowel plate contacts the part of the special-shaped pile that needs to be smoothed.

[0033] like Figure 3 As shown, there are two lifting mechanisms 5 located on both sides of the support frame 4, the two ends of the connecting frame 7 are respectively fixedly connected to the upper surface of an end plate 2, and the middle part of the connecting frame 7 is fixedly connected to the cylinder 6. The two lifting mechanisms 5 make the trowel plate rise and fall smoothly without tipping or tilting.

[0034] The trowel plate structure of the present application also includes a trowel plate oscillation pressing assembly fixedly connected to the support frame 4. The trowel plate oscillation pressing assembly can exert a force on the upper surface of the trowel plate to cause the trowel plate to vibrate. This vibration effect is equivalent to compacting the surface of the special-shaped pile, making the surface of the pile smoother when troweled.

[0035] The oscillating downward pressing component of the trowel plate can be a cylinder fixedly connected to the support frame. A rubber hammer is fixed to the end of the output shaft of the cylinder. The reciprocating motion of the cylinder output shaft drives the rubber hammer to beat the upper surface of the trowel plate to achieve a vibration effect.

[0036] In this embodiment, a preferred solution is provided for the oscillating downward pressing component of the trowel plate. Specifically, the oscillating downward pressing component of the trowel plate includes an oscillating driver 8, and the oscillating driver 8 is connected to the roller 10 through a connecting rod 9. The oscillating driver 8 can reciprocate in the circumferential direction to drive the connecting rod 9 to rise or fall, and the connecting rod 9 drives the roller 10 to rise or fall, thereby oscillating the upper surface of the trowel plate.

[0037] More specifically, the oscillation driver 8 includes an active roller 11 and a driven roller 12 fixedly connected to the active roller 11, wherein the active roller 11 is connected to a circumferential driver, and the active roller 11 and the driven roller 12 are respectively connected to a connecting rod 9, and a roller 10 is connected to the end of the connecting rod 9. The circumferential driver may be a motor, and the forward and reverse rotation of the active roller is adjusted by the forward and reverse rotation of the motor. Considering that the active roller cannot rotate excessively, it is difficult to control the forward and reverse rotation of the motor, so it is preferred to use a rotary cylinder, and the rotary cylinder uses a 90° rotary cylinder, thereby driving the active roller 11 to perform a 90° reciprocating rotation motion, and driving the two connecting rods 9 to rise and fall, thereby driving the roller 10 to rise and fall.

[0038] In a more preferred solution, the connecting rod 9 is connected to the roller 10 through a roller holder 13, and the connecting rod 9 and the roller holder 13 are rotationally connected. When the connecting rod 9 is lifted upward, the holder 13 is driven to rise, and the roller 10 rolls up immediately, thereby reducing the pressure on the upper surface of the trowel plate. When the connecting rod 9 is pressed downward, the holder 13 and the roller 10 are pressed downward accordingly, thereby increasing the pressure on the upper surface of the trowel plate.

[0039] Combination Figure 3 The connecting rod 9 connected to the active roller 11 and the connecting rod 9 connected to the driven roller 12 are distributed in an eight-shaped structure. In this eight-shaped distribution structure, when the active roller 11 and the driven roller 12 rotate synchronously, the pressure of one roller 10 must be increased and the pressure of the other roller 10 is reduced, and the oscillation effect is more obvious.

[0040] Two roller grooves 14 are provided on the upper surface of the trowel plate, and the roller grooves 14 penetrate the upper surfaces of the end plate 2, the bottom plate 1 and the inclined plate 3. Each roller groove 14 corresponds to a roller 10, and the roller 10 is located in the roller groove 14 so that the roller will not deviate.

[0041] The present application also provides a trowel machine, comprising the above-mentioned trowel plate structure for prefabricated part production.

[0042] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
