Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to an adjustable screed pad device for a road paver. Background Technology

[0002] In asphalt or water-stabilized pavement construction, the initial paving thickness control directly affects the pavement smoothness and joint quality. Currently, simple support components such as timber and steel blocks are commonly placed under the paver's screed for temporary support and to control the paving layer thickness. However, this traditional support method has the following drawbacks: 1. Inaccurate thickness adjustment: The fixed specifications of the timber or steel blocks prevent flexible adjustment according to different construction thicknesses, easily leading to uneven pavement thickness at joints. 2. Low construction efficiency: Each adjustment requires manual placement, measurement, and replacement, which is cumbersome and time-consuming. 3. Poor stability and large errors: During construction, vehicle vibration or temperature fluctuations can cause the blocks to shift, resulting in changes in the screed elevation and affecting pavement smoothness. 4. Poor versatility: Different paver models or different pavement structure layer thicknesses require various block specifications, causing inconvenience in management and use.

[0003] Therefore, there is an urgent need for an adjustable pad block device that can be quickly adjusted, stably positioned, and precisely control the initial paving thickness of the paver, in order to improve construction quality and work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable screed pad device for road pavers, which can quickly, conveniently and accurately control the loose thickness of road material when the paver starts, ensuring road surface smoothness and improving construction quality.

[0005] The present invention provides an adjustable paver screed pad device, comprising a rectangular upper pad and a lower pad. The upper pad extends horizontally along its length and horizontally along its width. Reinforcing plates are symmetrically and vertically fixed to both sides of the upper pad in the horizontal direction, for connecting and fixing it to the paver screed position. The reinforcing plates are right-angled triangles, with their right-angled bases connected to the upper pad and extending to the rear of the upper pad. The lower pad is positioned below the upper pad to support the paver screed. The rear side of the lower pad is vertically fixed to a rectangular back plate. The bottom edge of the back plate is connected to the lower pad. The left and right sides of the back plate are flush with the left and right sides of the lower pad. The back plate is located between the two reinforcing plates and its upper side is higher than the upper pad. The upper pad has threaded holes at the four corners, and the threaded holes are connected to the support screws. The upper pad has through holes symmetrically arranged vertically in the middle, and sliding screws are installed in the through holes. The lower end of the sliding screw is fixedly connected to the lower pad. The stud heads of the support screw and the sliding screw face upward, and the upper section of the upper pad is threaded with fastening nuts.

[0006] Furthermore, the upper pad, lower pad, reinforcing plate, and back plate are made of steel plates connected by welding, and their surfaces are treated with blackening.

[0007] Furthermore, the lower end of the sliding screw is connected to the lower pad by welding.

[0008] This utility model provides an adjustable screed pad device for road pavers. By incorporating threaded support screws and sliding screws on the upper pad, the device achieves continuous adjustment of the screed support height, thereby precisely controlling the initial paving thickness. The device is compact, flexible in adjustment, and reliable in positioning, allowing for rapid elevation setting under different construction conditions to ensure smooth road joints and consistent thickness. Compared to traditional wooden blocks or fixed shims, it significantly improves construction efficiency and quality, reduces repeated manual adjustments, and possesses high practicality and promotional value.

[0011] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an adjustable road paver screed pad device.

[0012] like Figures 1-5As shown, an adjustable paver screed pad device includes a rectangular upper pad 1 and a lower pad 2. The upper pad 1 extends horizontally and vertically along its length. Reinforcing plates 3 are symmetrically and vertically fixed to the left and right sides of the upper pad 1, for connecting and fixing it to the paver screed position. The reinforcing plates 3 are right-angled triangles, with their right-angled bases connected to the upper pad 1 and extending to the rear of the upper pad 1. The lower pad 2 is positioned below the upper pad 1 to support the paver screed, and its rear side is vertically fixed. A rectangular back plate 4 is connected, with its bottom edge connected to the lower pad 2. The left and right sides of the back plate 4 are flush with the left and right sides of the lower pad 2. The back plate 4 is located between the two reinforcing plates 3 and its upper side is higher than the upper pad 1. The upper pad 1 has threaded holes 8 vertically set at the four corners, and the threaded holes 8 are threaded to support screws 5. The upper pad 1 has through holes 10 vertically set symmetrically on the left and right sides, and sliding screws 6 are set in the through holes 10. The lower end of the sliding screws 6 is fixedly connected to the lower pad 2. The stud heads of the support screws 5 and the sliding screws 6 face upwards, and fastening nuts 7 are threaded to the upper section of the upper pad 1.
