Segment difference adjusting device and ironing plate

Abstract

The invention discloses a segment difference adjusting device and an ironing plate. The segment difference adjusting device comprises a frame body, a power part, a driving wheel, a driven wheel, a mounting base, a screw rod, a threaded block, a sliding block and a side plate. The power part is connected with the frame body; the driving wheel is connected with the power part and is driven by the power part to rotate; the driven wheel is connected with the driving wheel through a chain and is driven by the driving wheel to rotate; a mounting base is connected with the frame body; the screw rod is connected with the mounting base through a bearing, is connected with the driven wheel and is driven by the driven wheel to rotate in the mounting base; the threaded block is in threaded fit with the screw rod; the sliding block is connected with the threaded block and arranged in a sliding groove, close to the side plate, in the frame body in a sliding mode. And the extension direction of the side plate is the same as that of the screw rod, and the side plate is connected with the sliding block. The device is simple in structure, firm and reliable, manual adjustment is replaced with drivingof the power part (such as a hydraulic motor), the tedious operation of manual adjustment is omitted, the labor intensity is reduced, and the adjustment rapidity is improved.

Description

technical field [0001] The invention specifically relates to a step difference adjusting device and a screed. Background technique [0002] The step difference adjustment device is an indispensable part of the telescopic screed, and currently mainly includes such as figure 1 The shown screw group mechanism and figure 2 As shown in the four-bar linkage mechanism, the adjustment method of the two is manual adjustment. figure 1 When the screw group mechanism is adjusted, the fastening bolts need to be loosened, and the chain needs to be disassembled to adjust the pre-elevation angle. The operation is relatively cumbersome, and the overall rigidity of the structure is poor, and the stability is insufficient, which weakens the anti-torsion ability of the telescopic section; figure 2 The overall structural rigidity of the four-bar linkage mechanism is good and the structure is stable. The adjustment of the height difference and elevation angle is realized by manually operating...

Problems solved by technology

figure 1 When the screw group mechanism is adjusted, the fastening bolts need to be loosened, and the chain needs to be disassembled to adjust the pre-elevation angle. The operation is relatively cumbersome, and the overall rigidity of the structure is poor, and the stability is insufficient, which weakens the anti-torsion ability of the telescopic section; figure 2 The overall structure of the four-bar linkage mechanism is good in rigidity and stable in structure. The adjustment of height difference and elevation angle is realized by manually operating the screw and nut. sex
