Positioning method, positioning device and positioning sleeve part of section arm tail sliding block of cargo boom

Abstract

The invention relates to the technical field of cranes, and discloses a positioning method, a positioning device and a positioning sleeve part of section arm tail sliding blocks of a cargo boom, the positioning method comprises the following steps of acquiring an outer frame part (1) used for simulating an outer section arm (1), wherein the outer section arm is arranged on the outer side of an inner section arm (2) of the cargo boom in a sleeving manner and can stretch out and draw back relative to the inner section arm (2), the inner section arm (2) comprises an inner section arm main body (21) and and a sliding block installed on the inner section arm main body (21); positioning the outer frame part (1) on the outer side of the inner section arm (2); and adjusting the gap between the sliding block and the inner surface of the outer frame part (1) to reach a preset clearance value. According to the technical scheme, the slide block can be positioned on the section arm, so that the section arms of the cargo boom can keep the same center after being assembled, and the telescopic stability of the section arm is ensured. According to the technical scheme, the positioning difficulty ofthe sliding block is greatly simplified, and the assembling efficiency and the production period of the cargo boom can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a positioning method, a positioning device and a positioning kit for a slider at the end of a jib of a boom. Background technique [0002] As the main force-bearing component of the crane, the telescopic boom generally accounts for 13% to 20% of the weight of the whole machine, and the proportion of its weight is even larger in large cranes. Therefore, the structural performance of the telescopic boom not only affects the safety and reliability of the operation, but also an important factor that determines the quality and economic cost of the whole machine, especially for the performance of the telescopic boom of medium and large tonnage cranes in the case of large and high lifting heights. Impact matters. [0003] The telescopic arm is a box-shaped thin arm member, and the sections of the arms can slide relative to each other to realize the automatic expansion and contraction of...
