Problems solved by technology

If the pressure between the rubber plate and the road surface is too high, the rubber plate will inevitably wear out quickly, and even the road surface may be damaged; if the pressure is not enough, it will be difficult to ensure the sealing performance

Embodiment Construction

[0023] Specific embodiments of the present invention are given below. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent transformations made on the basis of the technical solutions of the present application fall within the protection scope of the present invention and comply with the foregoing technical solutions.

[0024] Such as Figure 1 to Figure 4 As shown, the sealing structure of a vacuum compaction roller of the present invention includes an upper steel plate 1 and two rubber plates 2 symmetrically installed on the left and right sides of the bottom surface of the upper steel plate 1. The bottom surface of each rubber plate 2 is provided with The arc-shaped grooves to which the steel wheels 3 fit, and the two steel wheels 3 are respectively arranged under the arc-shaped grooves on the bottom surface of the corresponding rubber plate 2; two side steel plates 10 with a thickness of 50 mm are symmetrically arra...

Abstract

The invention discloses a sealing structure for a vacuum compaction road roller, and belongs to the technical field of engineering machinery. The sealing structure comprises an upper steel plate, a rubber plate, a steel wheel, a side steel plate, a rubber backing plate, a crawler device and a side supporting plate, a hydraulic motor drives a driving sprocket through a belt, the driving sprocket is matched with a crawler chain to drive a crawler rubber belt, an onboard hydraulic circuit supplies oil for the hydraulic motor, synchronization of the linear speed of the crawler rubber belt and the linear speed of the steel wheel is ensured through a control device, a guide sprocket can function in guiding, a dragging wheel supports the crawler rubber belt, and the lower portion of the dragging wheel and a road surface are compressed, so that tightness is kept. The crawler device is skillfully used, friction between rubber and the road surface is transformed into friction between the rubber and the steel plate, friction force is remarkably reduced, and the road surface cannot be damaged. The simple sealing structure meets vacuum degree requirements of vacuum compaction.

Description

Technical field [0001] The invention belongs to the technical field of engineering machinery, and specifically relates to a sealing structure of a vacuum compaction roller. Background technique [0002] At present, one of the difficulties of vacuum compaction rollers is the structure of the sealed space. The sealed space involves the cooperation and sealing of the steel wheel and the rubber plate on the upper and left and right sides, and the cooperation and sealing of the rubber plate and the ground. Because the steel wheel and the rubber plate slide relatively, it is easy to leak air and it is difficult to effectively seal. There is also relative sliding between the rubber sheet and the ground, and the ground is not as well sealed as rubber. If there is too much pressure between the rubber sheets on the road surface, the rubber sheets will inevitably wear quickly, and even the road surface may be damaged; and it is difficult to ensure the sealing performance if the pressure i...
