Description
Technical Field
The utility model relates to an elevation angle adjusting device of flexible screed belongs to the paver field.
Background
The screed of paver in the existing market is mostly mechanical assembly type, and mainly under the same width of paving, the use cost of the mechanical assembly screed is lower than that of the hydraulic telescopic screed. However, when the mechanical assembling screed is used, the screed needs to be assembled manually, and particularly needs to be disassembled manually when paving a road surface with a variable paving width, which wastes labor and time, so that the mechanical assembling screed is behind a telescopic screed in mobility and convenience in use. Under the condition that the current labor cost is continuously increased, the hydraulic telescopic ironing plate gradually becomes the mainstream trend. Due to the limitation of the structure of the hydraulic telescopic screed plate, the rigidity of the telescopic section is different from that of the basic section, and the two sections of screed plates are not consistent in elevation angle due to torsion caused by the resistance of a paving material and the friction of a paving road surface in the paving process, so that the quality of the paving road surface is influenced. The elevation angle adjustment of the telescopic screed plate of the traditional paver cannot realize left-right synchronous adjustment or even cannot be realized.
The existing paver telescopic screed telescopic section difference and elevation angle adjusting device (CN207987687U) comprises a lower connecting plate, a lower frame plate, an upper guide rail plate and a lower guide rail plate, wherein the slideway surfaces of the upper guide rail plate and the lower guide rail plate are oppositely arranged to form a slideway; the left sliding block and the right sliding block are positioned at two ends of the slideway; the left sliding block is in threaded connection with the left end of the threaded rod, and the right sliding block is in threaded connection with the right end of the threaded rod; the lower end of the upper frame is provided with a left rotating shaft and a right rotating shaft; the upper end of the left swing rod is connected with the left rotating shaft to form a rotating pair, and the lower end of the left swing rod is connected with the left sliding block to form a rotating pair; the upper end of the right swing rod is connected with the right rotating shaft to form a rotating pair, and the lower end of the right swing rod is connected with the right sliding block to form a rotating pair; the left end of the threaded rod is provided with a nut to form a double-nut locking structure. The angle of the swing rod is driven by the screw rod to change, so that the angle of the frame of the telescopic section is changed. The elevation angle adjusting mechanism is complex in structure, high in processing difficulty and high in requirement on skills of operators, elevation angle adjustment and altitude difference adjustment functions are integrated together, mutual influence is caused in the adjusting process, and construction quality is seriously influenced.
Another paver and flexible screed (CN108797280A) thereof, the paver includes a frame and a flexible screed and a basic screed mounted on the frame, the flexible screed includes: the telescopic ironing frame is arranged on the frame corresponding to the basic ironing frame of the paver; and the adjusting device is used for adjusting the elevation angle of the ironing plate of the telescopic ironing frame, is arranged on the rack, and is respectively connected with the telescopic ironing frame and the basic ironing frame. The angle of the supporting rod connected with the telescopic frame is changed by adjusting the hexagonal spiral, so that the telescopic frame is driven to rotate, and the change of the elevation angle is realized. Because the hole axle cooperates many, the machining precision is high, and production efficiency is low.
Meanwhile, the elevation angle adjusting mechanisms mentioned in the two schemes are arranged on two sides of the telescopic frame, and are required to be adjusted in sequence by left and right turns during adjustment, so that the requirement on the skill of an operator is high, the integral synchronous adjustment of the elevation angles of the ironing plate frame of the telescopic section cannot be realized, once the single-side adjustment amount is too large, the clamping stagnation of the other side can be caused, the adjusting efficiency is restricted, and the adjustment cannot be performed in serious cases, so that the operation quality and the construction efficiency are influenced.
