Abstract

The invention discloses a self-resetting telescopic pin device for a leveling large arm of a paver. The self-resetting telescopic pin device comprises pin supports and large arm telescopic pins, and the pin supports and the large arm telescopic pins are arranged on the two sides of a paver body rear plate. The pin supports are each of a cylindrical cavity structure. A reset spring is arranged in a cavity of each pin support. One end of each large arm telescopic pin is sleeved with the corresponding reset spring, and the other end of the large arm telescopic pin is connected with a control handle through a flexible shaft. Preferably, the end, away from each flexible shaft, of the corresponding large arm telescopic pin is provided with a step-like structure. One end of each reset spring is positioned through the step-like structure of the corresponding large arm telescopic pin, and the other end of the reset spring is positioned through the end of the corresponding pin support. Preferably, pressing plates are arranged at the ends, away from the flexible shafts, of the pin supports. The large arm telescopic pins penetrate through the pressing plates, and the step-like structures of the large arm telescopic pins are clamped with the pressing plates. The self-resetting telescopic pin device has the advantages of being high in reliability, good in economical efficiency, flexible and convenient to control and the like, and the operation convenience and configuration economical efficiency of the large arm telescopic pins of the paver are achieved.

Description

technical field [0001] The invention relates to a self-resetting telescopic pin device used for leveling the boom of a paver. Background technique [0002] In the field of road construction machinery and paver technology, the telescopic pin of the boom is a necessary device for a machine transfer site. It has many structural forms, among which: [0003] Hand toggle type (that is, traditional mechanical type): its structural form is to install the handle directly on the telescopic pin, and manually toggle the handle to achieve the expansion and contraction of the pin. This structural form has the advantages of simple structure and low cost, but it is inconvenient to operate. Many people control the machine, and there are potential safety hazards. [0004] Hydraulically controlled boom telescopic pin: the telescopic pin is driven by an oil cylinder and controlled by an independent hydraulic system. Its structural form is convenient and flexible to control, but the cost is hig...
