Description

Technical Field

[0001] This utility model relates to the field of screed technology for pavers, specifically a hydraulic leveling mechanism for screeds of pavers. Background Technology

[0002] A paver is a construction device mainly used for paving various materials for the base and surface layers of highways. It consists of various systems working together to complete the paving work, primarily including a traveling system, a hydraulic system, and a material conveying system. The paver screed is a key working component, mainly used to level, shape, and pre-compact the mixed paving materials such as asphalt concrete and stabilized soil conveyed by the auger distributor, providing favorable working conditions for further compaction by the subsequent roller.

[0003] When existing paver screeds are in use, asphalt mixtures and other materials flow and are spread on the screed, the aggregates (such as sand and gravel) have high hardness, which will cause relative sliding and friction with the screed surface. Over time, the part of the screed bottom plate that contacts the material will gradually wear down, the surface will become rough, and even grooves and scratches will appear, which will affect the use. Moreover, when the screed bottom plate is severely damaged, the entire bottom structure needs to be replaced, which is not only more troublesome to operate, but also more costly.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-5 This utility model discloses a hydraulic leveling mechanism for a paver screed, comprising a mounting base 1, a screed body 11, a connecting plate 12, and multiple contact plates 3. The mounting base 1 and the connecting plate 12 form an installation structure for mounting other structures. The screed body 11 is the main body of the paver screed, and the multiple contact plates 3 are in contact with the road surface. The screed does not directly contact the ground. Hydraulic push rods 13 are provided on both sides of the connecting plate 12. The bottom of the hydraulic push rods 13 is connected to the screed body 11, that is, the screed is extended and retracted through the hydraulic push rods 13.

[0027] The mounting base 1 has rotating openings 2 on both sides, and rotating bolts 21 are provided on both sides of the outer side of the connecting plate 12. The rotating bolts 21 are rotatably installed in the rotating openings 2. An electric telescopic rod 14 is hinged to the bottom inner side of the mounting base 1. The connecting plate 12 is hinged to the other side of the electric telescopic rod 14, that is, it can be extended and retracted by the electric telescopic rod 14. Through the hinge structure at both ends, the rotating bolts 21 can be rotated in the rotating openings 2, so that the bottom structure faces outward, which is convenient for replacing the damaged floor 3. When the ironing board is adjusted to the bottom, there is a limiting block structure on the inner side of the mounting base 1, which limits the connecting plate 12, thereby leveling the connecting plate 12 and the ironing board.

[0028] A connecting seat 22 is provided at the bottom of the screed body 11. The connecting seat 22 is fixedly connected to the bottom of the screed. An installation component is provided at the bottom of the connecting seat 22, which includes multiple installation rails 33. An installation groove 23 is provided on one side above the connecting seat 22. An installation strip 31 is provided on the contact plate 3. The installation strip 31 is slidably connected to the installation rails 33. That is, the contact plate 3 is installed at the bottom by connecting the installation rails 33 through the installation strip 31. Conversely, it can be disassembled. When the paver is in use, the contact plate 3 touches the ground, thereby protecting the screed and effectively preventing damage to the screed. Even if the contact plate 3 is damaged, only the damaged contact plate 3 needs to be replaced. There is no need to replace the entire structure, which not only saves costs but also makes replacement more convenient. Both the contact plate 3 and the connecting seat 22 are made of heat-conducting materials to ensure that the heat of the screed can be transferred.

[0029] The mounting groove 23 has multiple first screw holes 24 on its inner side, and a mounting cover 4 is provided above the mounting groove 23. The first screw holes 24 are provided with internal hex bolts 34, which are threaded to the first screw holes 24. The bottom of the internal hex bolts 34 is provided with a first fixing bolt 35. The mounting strip 31 has a first fixing port 32 on its inner side. The first fixing bolt 35 is installed and removed from the first fixing port 32. After the mounting strip 31 is installed, the first fixing bolt 35 is aligned with the first fixing port 32. At this time, by rotating the internal hex bolts 34 on the outside, the first fixing bolt 35 is inserted into the first fixing port 32, thus fixing the mounting strip 31 and the floor 3.

[0030] The bottom of the mounting cover 4 is provided with multiple hexagonal bolts 41, which are installed and removed from the socket head cap screws 34. The mounting groove 23 has second threaded holes 43 on both sides, and mounting bolts 44 are installed inside the second threaded holes 43. The mounting bolts 44 are threadedly connected to the second threaded holes 43. The mounting bolts 44 are provided with second fixing bolts 45. The mounting cover 4 has second fixing ports 42 on both sides, and the second fixing bolts 45 are installed and removed from the second fixing ports 42. When all the first fixing bolts 35 are inserted into the first fixing ports 32, the hexagonal bolts 41 align with the hexagonal holes at the top of the socket head cap screws 34. That is, by installing the mounting cover 4, the hexagonal bolts 41 are inserted into the inside of the socket head cap screws 34, making the socket head cap screws 34 unable to rotate. At this time, the second fixing bolts 45 on both sides align with the second fixing ports 42. That is, by rotating the mounting bolts 44 on the outside, the second fixing bolts 45 are inserted into the second fixing ports 42, thereby fixing the mounting cover 4.

[0031] The working principle of this utility model is as follows: The hydraulic push rod 13 drives the ironing board to extend and retract. Through the hinged structure at both ends, the rotating bolt 21 rotates within the rotating port 2, allowing the bottom structure to face outwards, facilitating the replacement of the damaged floor mat 3. The mounting strip 31 connects to the mounting rail 33, allowing the floor mat 3 to be installed at the bottom; conversely, it can be disassembled. After the mounting strip 31 is installed, the first fixing bolt 35 aligns with the first fixing port 32. At this point, by rotating the hexagonal socket bolt 34 from the outside, the first fixing bolt 35 is inserted into the first fixing port 32, thus fixing the mounting strip 31 and the floor mat 3. When all the first fixing bolts 35 are inserted into the first fixing port 32... Then, the hex bolt 41 aligns with the hexagonal opening at the top of the socket head cap 34. By installing the mounting cover 4, the hex bolt 41 is inserted into the inside of the socket head cap 34, preventing the socket head cap 34 from rotating. At this point, the second fixing bolts 45 on both sides align with the second fixing openings 42. By rotating the mounting bolt 44 from the outside, the second fixing bolts 45 are inserted into the second fixing openings 42, thus fixing the mounting cover 4. When the paver is in use, the screed is protected by the ground contact plate 3, effectively preventing damage to the screed. Even if the ground contact plate 3 is damaged, only the damaged ground contact plate 3 needs to be replaced; there is no need to replace the entire structure, saving costs and making replacement more convenient.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
