Double-steel-wheeled vibratory road roller with hydraulic pipe fastening device

Abstract

The invention discloses a double-steel-wheeled vibratory road roller with a hydraulic pipe fastening device. The double-steel-wheeled vibratory road roller comprises a rear frame with two threaded holes, wherein a double-ended bolt is fixedly screwed into each threaded hole; the hydraulic pipe fastening device which mainly comprises a first rubber plate and a second rubber plate is arranged on the rear frame; the first rubber plate and the second rubber plate are provided with a threaded hole respectively, are butted together, and are fixedly screwed on the rear frame through the two double-ended bolts; the end parts of the first rubber plate and the second rubber plate are respectively provided with a semi-mounting hole for clamping a hydraulic pipe; the two semi-mounting holes are butted together to form a mounting hole; and the distance between the bottom of the mounting hole and the flat surface of the rear frame is 60 to 80mm. By the double-steel-wheeled vibratory road roller, the problem that hydraulic pipes are frequently abraded is effectively solved, and the safety of the hydraulic pipes and the normal operation of the double-steel-wheeled vibratory road roller are ensured.

Description

technical field [0001] The invention relates to a double steel wheel vibratory road roller with a hydraulic pipe fastening device in the field of construction machinery. Background technique [0002] The vibratory roller is a kind of earthwork engineering machinery integrating mechanical, hydraulic and electrical technologies. It is a mechanism for compacting soil layers and rock filling through various components, such as figure 1 As shown, in the existing double-drum road roller, after wrapping the hydraulic pipes including the vibration pump, drive pump, fuel tank, steering gear, etc. coming out from under the operating table with the wire protection bag (8), they are directly placed on the hinge joint (9) enters the hood above the rear frame (1). Because the front vehicle frame and the rear vehicle frame (1) are connected on the articulated joint (9) with pin shafts, the rear vehicle frame (1) and the articulated joint (9) are rotating, so the wire protection bag (8) an...

AI Technical Summary

Problems solved by technology

Because the front vehicle frame and the rear vehicle frame (1) are connected on the articulated joint (9) with pin shafts, the rear vehicle frame (1) and the articulated joint (9) are rotating, so the wire protection bag (8) and The hydraulic pipes in the line protection bag (8) are worn out one after another. Once the hydraulic pipes are worn out, the double-drum vibratory roller cannot operate normally, which brings great trouble to the work.
