Abstract

The invention relates to the technical field of a crawler-type chassis, in particular to a cylinder slideway double-limiting telescopic crawler-type chassis. The cylinder slideway double-limiting telescopic crawler-type chassis comprises a left crawler frame, a left sliding assembly, a right crawler frame, a right sliding assembly, a center rotating frame and hydraulic oil cylinders; the left crawler frame is fixedly connected with the left sliding assembly; the right crawler frame is fixedly connected with the right sliding assembly; the left sliding assembly and the right sliding assembly are respectively connected with the center rotating frame; and the hydraulic oil cylinders are arranged between the center rotating frame and the left crawler frame as well as the right sliding assembly. According to the cylinder slideway double-limiting telescopic crawler-type chassis, the structure is easy to process; when the processing difficulty is reduced, the machining quantity is also reduced; and when the integral cylinder slideway double-limiting telescopic crawler-type chassis works, the crawler frames extend to the greatest extent to increase the earthing width so as to improve the stability of the integral cylinder slideway double-limiting telescopic crawler-type chassis in the working process; when the integral cylinder slideway double-limiting telescopic crawler-type chassis travels and transports, the crawler frames retract to the greatest extent, so that the cylinder slideway double-limiting telescopic crawler-type chassis can pass through a narrow channel, the transportation size of a drilling machine can be reduced and the cylinder slideway double-limiting telescopic crawler-type chassis is easy to use and popularize.

Description

technical field [0001] The invention relates to the technical field of a crawler-type chassis, in particular to a double-limiting retractable crawler-type chassis of a cylindrical slideway. Background technique [0002] The telescopic crawler chassis is mainly used on rotary drilling rigs, crawler cranes and other equipment. Due to the modular design and the realization of the function of the telescopic crawler frame, it can improve the adhesion and meet the stability of the equipment. It has the advantages of convenient transportation, Advantages of high disassembly and assembly efficiency. Because the crawler frames on the left and right sides can rely on hydraulic cylinders to realize telescopic movement in the width direction, which greatly broadens the working range of the equipment and can adapt to narrow passages and working spaces, it has been gradually used widely. [0003] The general structure of the existing telescopic crawler chassis is usually a rectangular st...
