Problems solved by technology

[0004] In view of the above, when there are gravel accumulations or sandy soil bulges on the road surface, the rolling roller directly rolls the road surface. Due to the large slope of the road surface caused by the accumulation of stones, the center of gravity of the rolling wheel will deviate, resulting in "top-heavy" rolling wheels. If there is not enough grip to fit the road surface for rolling, it will affect the smooth progress of road construction, and when the sand on the road surface is dry and fluffy for rolling, the phenomenon will make the road surface and the rolling wheel contact each other. The contact is not complete, resulting in corresponding slipping and repelling, and the basic goal of effective control of construction quality cannot be achieved. The invention provides a special sprinkler rolling vehicle for road construction

Embodiment 1

[0031] like Figure 1-Figure 4 As shown, the present invention provides a special sprinkler rolling vehicle for road construction, and its structure includes a wheel 1, a cab 2, a waterproof baffle 3, and a rolling structure 4. The wheel 1 is installed at the bottom of the cab 2, and the driving One side of the chamber 2 is welded with a waterproof baffle 3, the bottom of the waterproof baffle 3 is provided with a rolling structure 4, and the rolling structure 4 includes a rolling roller 41, a positioning groove 42, a half-ring drive 43, a frame 44. Adhering structure 45, the two ends of the rolling roller 41 are installed with an adhering structure 45, and the outside of the two is surrounded by a frame 44, and the middle part of the frame 44 is embedded with a half-ring drive 43 through the positioning groove 42 Forming an integrated structure with it, the top of the half-ring drive 43 is fixedly connected to the connection position at the bottom of the waterproof baffle 3, ...

Embodiment 2

[0033] like Figure 5-Figure 7As shown, on the basis of Embodiment 1, the present invention combines the mutual cooperation of the following structural components. The pressurizing device 535 includes an opening and closing arc 351, an iron ball 352, a positioning frame 353, a telescopic pocket 354, and a top bag 355 , the opening and closing arc 351 is a fan-shaped structure, and its upper part is welded and connected between the telescopic pockets 354. The three telescopic pockets 354 form a triangular structure, and a positioning frame 353 is embedded and connected between them. The positioning frame 353 and the top-position bag 355 are fitted together in a movable snap-fit ​​manner, the linear distance between the top-position bags 355 is shorter than the diameter of the iron ball 352, and the expansion device 531 includes an embedded ring 1a1 and a torsion spring 1a2 1. The grip claws 1a3, the grip claws 1a3 are fixedly connected by the embedded ring 1a1, and the top ther...

Abstract

The invention discloses a special watering and rolling vehicle for road construction, the special watering and rolling vehicle structurally comprises wheels, a cab, a waterproof baffle and a rolling structure, the wheels are mounted at the bottom of the cab, the waterproof baffle is welded to one side of the cab, and the rolling structure is arranged at the bottom of the waterproof baffle. The gravity impact force of the iron ball is greater than the limited extrusion force between the iron ball and the jacking bag, the in-place iron balls cause downward traction to the telescopic pockets, thesituation that the gravity center of the grinding roller in the middle deviates, consequently, the grinding roller has the'heaviness and lightness' lost rotation phenomenon, and smooth road construction is affected is avoided, the contact area with the road surface can be increased through the structure of the beveling plate, and friction force between the cutting edge and the road surface and friction force between the guide sliding way and the road surface are increased in an auxiliary mode. The road holding device can be effectively contacted with dry and fluffy sandy soil so as to increase road holding force, and the problem that the construction quality cannot be effectively controlled when the dry and fluffy sandy soil on a road surface is rolled is avoided.

Description

technical field [0001] The invention relates to the field of road construction machinery, in particular, it is a special sprinkler rolling vehicle for road construction. Background technique [0002] The road roller, also known as the soil compactor, is a kind of equipment for road construction. The road roller belongs to the category of road equipment in construction machinery. For practical operation, it can roll sandy, semi-cohesive and cohesive soil, roadbed stabilized soil and asphalt concrete pavement layer. The road roller is suitable for various compaction operations due to the gravity of the machine itself, so that the rolled layer will produce permanent deformation and compactness. , The road roller is divided into two types: steel wheel type and tire type. [0003] When there are gravel accumulations or raised sand on the road surface, the rolling rollers will directly roll the road surface. Due to the large slope of the road surface caused by the accumulation of...
