Description

Technical Field

[0001] The utility model relates to the technical field of road surface flattening equipment, in particular to outdoor road surface flattening equipment for construction engineering. Background Art

[0002] When repairing roads, a road roller is required to level and compact the paved roads. A road surface flattening device with publication number CN218492212U discloses a road roller, a roller frame, and a road roller. The roller frame is mounted on one side of the road roller, and the road roller is rotatably mounted on one side of the roller frame. A fast-attachment and disassembly mechanism is provided between the road roller and the roller frame. The structure of the quick-attachment mechanism of the James-type car hook facilitates the workers to quickly connect and disassemble the road roller and the roller frame, thereby increasing the convenience of using the road roller and increasing the practicality and popularity of the road roller. The water pump can be quickly connected to the water tank inside the roller through the rubber hose, clamp, water pump, water inlet pipe and other structures, so as to timely wash the roller, and the mud turning plate arranged on the upper side of the scraper can prevent mud from accumulating on the scraper, making the scraper cleaning more efficient; the roller of this roller has a fixed length, so in the unidirectional forward work of the roller, the range of road flattening is limited. If the width of the road is much larger than the length of the roller, the roller needs to move back and forth many times, resulting in low flattening efficiency;

[0003] There may already be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0011] Beneficial Effects

[0012] The utility model provides an outdoor road surface flattening device for construction engineering, which has the following beneficial effects compared with the prior art: a middle pressure roller is attached to the road surface to be flattened, and a user controls the extension and retraction of a first hydraulic cylinder and a second hydraulic cylinder to make the edge pressure rollers on both sides of the middle pressure roller and a connecting pressure roller attached to the road surface to be flattened or leave the ground. For a moving device, the range of road surface flattening is adjusted, which is suitable for flattening roads of different widths and improves work efficiency. The vehicle body moves, the middle pressure roller attached to the road surface rotates on the middle frame, the edge pressure rollers rotate on the edge frame, and the connecting pressure rollers rotate on the mounting frame to flatten the road surface. The connecting pressure rollers are used to flatten the road surface that has not been flattened in the gap between the middle pressure roller and the edge pressure rollers.

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Embodiment: Through the personnel in this field, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection between the electrical components is completed in the working sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. Please refer to Figure 1-3 The vehicle body 1 drives the adjustment road pressing structure to move through the installation of the fixed bar frame 2. When the road width is small, the user controls the first hydraulic cylinder 6 and the second hydraulic cylinder 10 on both sides to be in a retracted state. At this time, only the middle pressing roller 4 is in contact with the road surface to be flattened. When the road width is large, the user controls the first hydraulic cylinder 6 and the second hydraulic cylinder 10 on both sides to be in an extended state. At this time, the middle pressing roller 4, the edge pressing rollers 8 on both sides, and the connecting pressing rollers 12 on both sides are in contact with the road surface to be flattened. The user can also control only the first hydraulic cylinder 6 and the second hydraulic cylinder 10 on one side according to the road width. The two hydraulic cylinders 10 are in an extended state. At this time, the middle roller 4, the edge roller 8 on one side, and the connecting roller 12 on one side are attached to the road surface to be flattened. For the moving device, the range adjustment of the road surface flattening is realized, which is suitable for the flattening of roads of different widths and improves the work efficiency. The vehicle body 1 moves, the middle roller 4 attached to the road surface rotates on the middle frame 3, the edge roller 8 rotates on the edge frame 7, and the connecting roller 12 rotates on the mounting frame 11 to flatten the road surface. The connecting roller 12 is used to flatten the road surface that has not been flattened in the gap between the middle roller 4 and the edge roller 8;

[0019] As a preferred embodiment, further, guide rods 13 are installed on both grooves 5, and the edge frame 7 is movably mounted on the guide rods 13. When the first hydraulic cylinder 6 is extended or retracted, the retracted end of the first hydraulic cylinder 6 drives the edge frame 7 to move on the guide rods 13, and the guide rods 13 play a role in protecting the retracted end of the first hydraulic cylinder 6.

[0020] As a preferred embodiment, further, the structure of the middle pressure roller 4 and the edge pressure roller 8 is the same;

[0021] Preferably, further, the length dimension of the connecting roller 12 is larger than the minimum spacing dimension between the middle roller 4 and the edge roller 8, so as to ensure that the unflattened position between the middle roller 4 and the edge roller 8 is flattened;
