Description

A crawler paver chassis

technical field

The invention relates to concrete paving equipment, in particular to a crawler-type paver chassis.

Background technique

Due to its own multi-functional structure including vibrating, paving, troweling, feeding, etc., the size and weight of the current paving equipment are relatively large, and the paving size can reach 19 meters. However, at present, rural roads with a width of 3 to 4 meters are still paved manually. The width of the paver is generally more than 6 meters. The roadbed of the rural road is too narrow to drive and can withstand the paver of dozens of tons. The normal driving speed of the paver is very slow, and it is very time-consuming for long-distance transitions. The paver chassis needs to be loaded with the conveying mechanism for feeding, as well as the engine, control unit, control unit and other components. How to simplify the paver chassis is an important problem in the manufacture of country road paver.

In the chassis of the above-mentioned crawler paver, a bracket is provided behind the door frame II, and the bracket includes at least two left and right parallel support plates.

The above-mentioned crawler paver chassis further includes a front swing arm, the rear part of the front swing arm is hinged on the gantry I, and the front swing arm and the gantry I are connected by an oil cylinder to achieve lifting or lowering.

In the chassis of the above-mentioned crawler paver, rear swing arms are respectively hinged behind the crawler, and the rear swing arm includes an outer arm and an inner arm, and the outer arm and the inner arm are connected by several connecting rods, and the crawler Both the inner and outer sides of the support are provided with shaft sleeves, and the rear ends of the outer arm and the inner arm are hinged with the crawler through the shaft sleeve; the gantry II and the inner arm are connected by an oil cylinder to achieve lifting or lowering.

In the above-mentioned crawler paver chassis, the rear end of the outer arm is hinged with a telescopic rod or a telescopic cylinder.

The chassis of the above-mentioned crawler paver also includes a conveying mechanism for conveying materials, the conveying mechanism is installed on the inner side of the gantry I and the gantry II, and a hopper is installed at the front end of the conveying mechanism.

In the chassis of the above-mentioned crawler paver, a push-roll mechanism is installed at the front end of the front swing arm, a sliding mold is installed at the rear end of the rear swing arm, and a smoothing mechanism is installed at the rear of the sliding mold.

The beneficial effects of the invention are as follows: the crawler-type chassis is a beam-frame structure, which greatly reduces the total weight of the whole machine. The front and rear swing arms are set to facilitate the installation or removal of attachments, which is conducive to long-distance equipment driving transitions. In the non-working state, the front and rear swing arms are raised, which is beneficial to protect the attachment from bumping.
