Description

Technical Field

[0001] The utility model relates to the field of building material equipment, in particular to a high-efficiency leveling machine for prefabricated concrete parts. Background Art

[0002] In order to shorten the construction period and reduce the impact on the on-site environment, many concrete components are prefabricated in factories in the modern construction industry. When making prefabricated concrete parts, the mixed concrete materials are put into the mold, and then the materials are flattened, compacted and smoothed. During the flattening process, the materials must be flattened both vertically and horizontally. If there is a shortage of materials in a certain area, it is necessary to refill and level it again. At present, there are two ways to level it manually, and there are also mechanical leveling machines. Manual leveling is inefficient and labor-intensive. Mechanical leveling can improve efficiency, but most of the current leveling machines use a pushing device or a pushing plate to push the material longitudinally from one end to the other. If the material being leveled is a long-rod-shaped concrete component that is narrow in width and the material feeding is relatively uniform, the efficiency improvement will be obvious; but for prefabricated components with a large width and that require multi-point feeding, the materials fed are mostly unevenly piled at multiple points. When the current leveling machine pushes the material longitudinally, the material flow is pushed forward and easily forms excess material accumulation that overflows to the rear of the pushing device or the pushing plate, while there is still a lack of material on both sides. Subsequent manual feeding is required, which greatly affects the efficiency improvement. In view of this, if the concrete prefabricated component leveling machine can be improved so that it can not only push and homogenize the accumulated materials horizontally, but also scrape the homogenized materials longitudinally, and can improve the operating efficiency through all-round leveling in the horizontal and vertical directions, it is a problem to be solved in this case.

The utility model improves a concrete precast component leveling machine, integrates a material-driving component, a scraping plate and a flattening component on a mobile frame which can move longitudinally, utilizes an impeller which can rotate forwards and backwards and is arranged on the material-driving component to move transversely back and forth during rotation to push and homogenize the accumulated concrete materials, and utilizes the scraping plate and the flattening component to scrape and roll the pushed materials when the mobile frame moves longitudinally, achieves peak-cutting and valley-filling through all-round leveling in the transverse and longitudinal directions, thereby reducing the work of subsequent material replenishment required for excess material in some areas and shortage of materials in some areas, thereby improving the working efficiency.

[0028] like Figures 1 to 6 As shown, the mobile frame 1 of the utility model includes a frame body 11, a guide rail 12 and a rack 14. The guide rail 12 is provided with a dovetail rail body and a slider that can be slidably engaged. The slider can move horizontally on the rail body but cannot move up and down.

[0029] like Figures 1 to 4 , Figure 7As shown, the flattening assembly 4 described in the utility model includes a pressure roller 41, an upper support plate 42, a lower support plate 43, an adjusting rod 44 and a compression spring 45. The pressure roller 41 is a rotatable gravity roller, and its core is provided with a core shaft with a bearing. The upper support plate 42, the lower support plate 43, the adjusting rod 44 and the compression spring 45 are each two pieces, and the two ends of the core shaft of the pressure roller 41 are respectively fixedly connected to the lower parts of the two lower support plates 43, and the upper ends of the two upper support plates 42 are both fixedly connected to the frame 11.

The compression spring 45 is placed between the upper support plate 42 and the lower support plate 43 and is sleeved on the adjusting rod 44.

[0030] The method of using the high-efficiency leveling machine for precast concrete parts described in the utility model is as follows:

[0031] The leveling machine is mounted above the precast concrete part 900 to be leveled, and the track height of the movable frame 1 is adjusted so that the scraping surface of the scraping plate 3 is higher than the upper surface of the precast concrete part 900 to be leveled. The gap formed allows the scraping plate 3 to reserve material for rolling by the flattening assembly 4 after scraping. The nut on the upper end of the adjusting rod 44 of the flattening assembly 4 is then adjusted so that the bottom of the pressure roller 41 can just contact the upper surface of the precast concrete part 900 to be leveled when the compression spring 45 is not pre-stressed. Start the driving motor of the mobile frame 1 and the motor 25 of the material-driving assembly 2. The mobile frame 1 moves forward intermittently in the longitudinal direction and pauses. The motor 25 of the material-driving assembly 2 drives the second gear 24 to rotate in a certain direction, driving the first gear 23 and the third gear 26 to rotate. The first gear 23 drives the impeller 22 to rotate while the third gear 26 also rotates. Under the action of the fixed rack 14, the rotating shaft of the third gear 26 drives the movable plate 21 to move horizontally. At this time, the impeller 22 moves the material to be homogenized and pushes it to the side. When the movable plate 21 moves horizontally to the end point, the motor 25 of the material-driving assembly 2 can be reversed. Similarly, the movable plate 21 can be driven to move in the opposite direction. The impeller 22 reverses to move the material in the opposite direction to be homogenized and push it to the other side. The mobile frame 1 moves forward intermittently in the longitudinal direction for another period of time, and the material-driving assembly 2 repeats the above actions until the mobile frame 1 completes the journey. At this point, the materials accumulated at multiple points are evenly dispersed by the material-driving component 2 and pushed to all places. The scraper plate 3 and the flattening component 4 flatten and compact the materials evenly dispersed by the material-driving component 2, and flatten them in all directions horizontally and vertically, thereby achieving peak shaving and valley filling, avoiding the problem of excess material in some areas and shortage of material in some areas.

[0032] The utility model improves a precast concrete part leveling machine, integrates a material-driving component 2, a scraping plate 3 and a flattening component 4 on a mobile frame 1 which can move longitudinally, utilizes an impeller 22 which can rotate forwards and backwards and is provided on the material-driving component 2 to move transversely back and forth during rotation to push and homogenize the accumulated concrete materials, and utilizes the scraping plate 3 and the flattening component 4 to scrape and roll the pushed materials when the mobile frame 1 moves longitudinally, achieves peak-cutting and valley-filling through all-round leveling in the transverse and longitudinal directions, thereby reducing the work of subsequent material replenishment due to overfilling in some areas and lack of materials in some areas, and improving the working efficiency.

[0033] In the description of the present invention, the words "first", "second", "third" and the like are used to define components. The use of "first", "second", and "third" is only for the convenience of simplifying the description and has no specific meaning of order, unless the "first", "second", and "third" are specifically stated.

Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
