Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to an elongated structure for the hot plate of a road shoulder construction paver. Background Technology

[0002] A paver is a type of construction machinery mainly used for large-area road surface construction, such as highways, railways, and airport runways. The screed is a key component of the paver; it is typically a long, strip-shaped metal plate with a smooth, flat bottom. During construction, it is kept at a high temperature by a heating system. The screed initially compacts and smooths the paving material, evenly spreading the road surface material according to the set thickness and slope, playing a decisive role in the smoothness of the road surface. However, during construction, situations arise where there is a height difference between the road shoulder and the road surface. The traditional flat screed structure cannot meet the construction requirements, resulting in on-site construction failing to meet acceptance standards. Utility Model Content

[0003] The purpose of this utility model is to provide an elongated screed plate structure for a road shoulder construction paver, in order to solve the problem mentioned in the background art where there is a height difference between the road shoulder and the road surface during construction, and the traditional flat screed plate structure cannot meet the construction requirements, resulting in the failure of on-site construction to meet acceptance requirements.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an elongated screed plate structure for a road shoulder construction paver, comprising a main frame, connecting plates at both ends of the main frame, a fixing plate on the lower outer side of the main frame and between the two connecting plates, a primary inclined pad fixedly connected to the lower surface of the fixing plate by bolts, a secondary inclined pad on the lower surface of the primary inclined pad, a screed plate between the lower surfaces of the two secondary inclined pads, adjusting screws threadedly connected to the four corners of the main frame, adjusting seats on the upper surface of the screed plate corresponding to the adjusting screws, the lower end of the adjusting screws being rotatably connected to the adjusting seats by connecting pins, and a vibrating shaft inside the main frame and between the two connecting plates.

[0005] Preferably, the main frame is a U-shaped metal sheet structure integrally formed by bending. Process holes are provided at both ends of the upper surface of the main frame near the connecting plate. A fixing nut is provided on the upper surface of the main frame at the position corresponding to the adjusting screw. The adjusting screw is threadedly connected to the fixing nut. Pipe openings are provided through the front and rear side walls of the main frame at the positions corresponding to the adjusting screw.

[0006] Preferably, the two connecting plates have openings at positions corresponding to the vibrating shaft, an eccentric roller is provided at the middle position of the vibrating shaft, and bearing seats are provided on the vibrating shaft and on both sides of the eccentric roller. The bearing seats are fixedly connected to the main frame by bolts.

[0007] Preferably, the primary inclined pad and the secondary inclined pad form a cuboid structure, and the outer side of the secondary inclined pad has a groove corresponding to the position of the bolt on the primary inclined pad.

[0008] Preferably, the lower end of the adjusting screw is rotatably connected to a rotating seat, the connecting pin is spliced ​​with the rotating seat, and the inner diameter of the shaft hole provided on the adjusting seat is larger than the outer diameter of the connecting pin.

[0009] Compared with the prior art, the beneficial effects of this utility model are: when there is a height difference between the road shoulder and the road surface during construction, it replaces the traditional flat slab structure. An extension structure is connected to the outside of the traditional slab by bolts. The extension structure is used to lay both right-angle and sloping road surfaces, which meets the construction requirements and ensures that the on-site construction meets the acceptance requirements.

[0018] In use, connecting plates 2 are fixedly welded to both ends of the main frame 1. Bolts are used to thread the entire elongated structure onto the outer end of the paver's screed plate. A fixing plate 3 is installed at the lower end of the main frame 1. A primary inclined pad 4 and a secondary inclined pad 5 are bolted to the lower end of the fixing plate 3. An adjusting screw 7 is threaded onto the main frame 1. The lower end of the adjusting screw 7 is rotatably connected to an adjusting seat 8 via a connecting pin 9. The adjusting seat 8 is fixedly connected to the screed plate 6. After tightening the adjusting screw 7, the upper end of the screed plate 6 is tightly pressed against the lower end of the secondary inclined pad 5. The height of the screed plate 6 at the lower end of the elongated structure is lower than that of the screed plate of the paver, and the thickness is the same as that of the first-level inclined pad 4 and the second-level inclined pad 5. After paving, the shoulder is perpendicular to the road surface and the shoulder is lower than the road surface. When a slope needs to be set between the shoulder and the road surface, the second-level inclined pad 5 is removed, and the adjusting screw 7 is tightened. The upper end of the screed plate 6 is tightly attached to the lower end of the first-level inclined pad 4. At this time, the screed plate 6 at the lower end of the elongated structure is set at an inclination. After paving, the shoulder and the road surface form a slope to meet the construction requirements. The elongated structure is driven by the vibrating shaft 10 to ensure the paving effect.

The cables of the internal heating equipment pass through the side walls of the main frame 1 through the pipe openings 13.

[0020] The two connecting plates 2 have openings 14 at positions corresponding to the vibrating shaft 10. The vibrating shaft 10 is connected to the rotating shaft structure of the paver's hot plate through the openings 14, transmitting power to the vibrating shaft 10. An eccentric roller 15 is provided in the middle of the vibrating shaft 10, which drives the eccentric roller 15 to rotate, thereby causing the elongation structure to vibrate.
