Embodiment 2

[0015] Embodiment 2, an excavator with a telescopic arm (5) of a telescopic mechanism, including a first telescopic arm (6), a butter sealing plate (7), a telescopic oil cylinder (9), a second telescopic arm (12 ). The telescopic arm (5) is connected with the bucket (1), connecting rod (2), rocker (3) and bucket cylinder (4) according to the traditional installation method of the excavator; the first telescopic arm (6) has a guide rail (13) and is equipped with a first pin shaft (8) and a guide wheel (10); the second telescopic arm (12) has a bolt block (14) and is equipped with a second Pin shaft (11); one end of the telescopic oil cylinder (9) is hinged with the first pin shaft (8) of the first telescopic arm (6), and the other end is hinged with the second pin shaft of the second telescopic arm (12) (11) Articulation, the length change of the telescopic arm is realized by controlling the stroke of the telescopic oil cylinder (9).

Embodiment 3

[0016] Example 3, see Figure 2 ~ Figure 6 . One end of the telescopic oil cylinder (9) is hinged with the first pin shaft (8) on the first telescopic arm (6), and the other end is hinged with the second pin shaft (11) on the second telescopic arm (12), so The guide rail (13) on the first telescopic arm (6) is matched with the inner cavity of the second telescopic arm (12), and the guide wheel (10) on the first telescopic arm (6) can be The upper end surface of the second telescopic arm (12) is free to roll, and the butter sealing plate (7) is connected with the bolt block (14) on the second telescopic arm (12) through bolts to prevent the first telescopic arm (6) ) and the lubricating oil in the cavity between the second telescopic arm (12), the guide rail (13) on the first telescopic arm (6) and the inner wall of the second telescopic arm (12) are fully lubricated, This ensures the working fluency and stability of the telescopic stick (5) during its length change. Within t...

Embodiment 4

[0017] Embodiment 4, on the basis of the original excavator, the present invention changes the traditional arm into a two-stage type, the first telescopic arm (6), and the second telescopic arm (12), respectively pass through the inner cavities of the two The first pin shaft (8) and the second pin shaft (11) are hinged to a telescopic oil cylinder (9). Under the premise of meeting the structural design and installation requirements of the telescopic oil cylinder (9), it can be flexible according to different working conditions. The working range of the working device can be changed by changing the length of the telescopic stick (5). Suitable for a variety of different workplaces. It better adapts to the current domestic and foreign market demand and expands the application range of the machine.

Abstract

The invention discloses a telescopic boom of an excavating machine. A first telescopic bucket rod, a telescopic oil cylinder and a second telescopic bucket rod are hinged to a first pin shaft and a second pin shaft to form a telescoping mechanism, and the telescoping mechanism is matched with the second telescopic bucket rod through a guide wheel and a guiding rail on the first telescopic bucket rod, and the elasticity of the first telescopic bucket rod is realized. By the connection of the first telescopic bucket rod and the second bucket rod to the two ends of the telescopic oil cylinder respectively, the stroke of the oil cylinder is controlled, and the working lengths of the bucket rods are changed, therefore, the working range of the excavating machine is changed. The telescopic boom provided by the invention has a unique advantage that one excavating machine is applicable to various working condition occasions, the efficiency is high, the performance is reliable, the structure is simple, the manufacturing is convenient, and the cost is low.

Description

technical field [0001] The invention relates to an excavator, in particular to an excavator telescopic arm. Background technique [0002] At present, in general earthwork excavation, slope trimming, river bottom dredging, etc., the former requires the excavator to provide sufficient digging force and efficient body rotation, soil loading and unloading actions to improve work efficiency, usually used It is realized by an excavator with a smaller digging radius (shorter stick); the latter two work targets are farther away from the fuselage, and an excavator with a larger digging radius (longer stick) is needed to achieve. Therefore, excavators with different working devices are usually selected according to different working conditions, which greatly increases the working cost. Contents of the invention [0003] The object of the present invention is to provide an excavator telescopic arm with a telescopic mechanism, which can flexibly adjust the length of the arm to be sui...
