Abstract
Description
Technical Field
[0001] This utility model relates to an integrated machine for smoothing and coating precast concrete components, belonging to the field of precast concrete component production technology. Background Technology
[0002] In the production of precast concrete components, after the concrete material is poured into the mold, the surface is roughly smoothed by vibration. Before the initial setting of the concrete, the surface is further smoothed and compacted to eliminate surface defects, water seepage channels within the concrete, and early plastic cracks. After the surface concrete has initially set, pits and sand holes are compacted. After pouring, the surface of the component is promptly covered with a plastic film for curing. Currently, the smoothing and film-coating processes are carried out manually. Affected by factors such as raw materials, temperature, air humidity, and wind, smoothing is difficult to control precisely, resulting in heavy grinding marks, poor appearance of the finished product, and high labor costs. When applying the film, the manual laying or rolling of the plastic film is slow, time-consuming, and labor-intensive, resulting in low efficiency for both smoothing and film-coating.

[0035] Example 2:
[0036] As attached Figure 6As shown, this embodiment is a further improvement based on embodiment one. Rubber anti-collision blocks 15 are installed at both ends of the traveling vehicle body 1.

[0037] The precast concrete components are positioned inside the two traveling carriages 1, with the left frame 11 and right frame 12 located above them. The plastic sheeting to be laid is wound onto the drum 75; as shown in the attached diagram. Figure 1-6 As shown, during operation, the integrated machine for smoothing and coating precast concrete components is located at the left end of the precast concrete component. Two parallel traveling vehicles 1 travel from left to right on the guide rail. The bidirectional winch 43 is started to release the wire rope, causing the lifting frame 3 to descend and press the two rubbing plates 63 onto the upper surface of the precast concrete component. The reduction motor 601 is started, and the reduction motor 601 drives the two rubbing plates 63 to alternately rub horizontally through the bearing connecting rod 603 and three sets of swing rods. Then, the two rubbing vibrating motors 69 on the top surfaces of the two rubbing plates 63 are activated. This simultaneous movement and rubbing eliminates surface unevenness, making the component surface smoother and more aesthetically pleasing. A smooth surface helps reduce cracks and voids, prevents moisture and harmful substances from seeping in, extends service life, and facilitates subsequent laying of plastic sheeting, ensuring better adhesion. The roll 75 of the plastic sheeting is positioned above the precast concrete component. The starting end of the plastic sheeting is pressed tightly against the left end of the precast concrete component. Simultaneously, the two rubbing plates 63 on the right end alternately rub horizontally, while the front and rear hydraulic cylinders 81 and 85 are activated, extending their hydraulic rods to push the corresponding front and rear swing arms 82 and 86, driving the front and rear torque motors 83 and 87 downwards, causing the front and rear drive wheels 84 and 88 to move in a certain direction. A constant pressure is applied to the rims of the front and rear rotating wheels 73 and 74. The front and rear torque motors 83 and 87 drive the front and rear drive wheels 84 and 88 to rotate, which in turn drives the front and rear rotating wheels 73 and 74 to rotate. The front and rear rotating wheels 73 and 74 drive the drum 75 to rotate, thereby laying the plastic sheet wound on the drum 75 onto the surface of the precast concrete component for maintenance. The front and rear torque motors can be set to rotate forward or backward, which can make the drum 75 rotate forward or backward to lay or roll up the plastic sheet. The oil rods of the front and rear hydraulic cylinders 81 and 85 retract, which drives the corresponding front and rear swing arms 82 and 86 and the front and rear torque motors 83 and 87 to move upward, so that the front and rear drive wheels 84 and 88 are separated from the front and rear rotating wheels 73 and 74, making it easier to remove the drum mechanism 7 and replace the drum 75. After the concrete precast right end is smoothed, the bidirectional winch 43 is started and the wire rope is retracted to lift the lifting frame 3 and the smoothing mechanism 6 to a high position, and the drum mechanism 7 stops working; ready for the next cycle of work.
[0038] This utility model features two rubbing plates 63 that vibrate simultaneously while rubbing alternately and automatically lay down plastic sheeting for curing. This saves time and effort, is reliable, has a reasonable design, and improves work efficiency.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
