Embodiment 1

[0024] This embodiment provides a telescopic outrigger for large-scale construction equipment that can be easily plugged in and out. Figure 1-4 The structure shown includes a pin shaft assembly 1, an outer telescopic joint 2, an inner telescopic joint 3 and a pin shaft supporting device 4, and this embodiment will be described in detail below with reference to the accompanying drawings.

[0025] The pin shaft assembly 1 includes a pin shaft 11 and a detachable handle 12 disposed at the end of the pin shaft 11 .

[0026] The outer telescopic section 2 and the inner telescopic section 3 are nested with each other to form the leg body, and a guide bar 5 is provided between the outer telescopic section 2 and the inner telescopic section 3 to control the gap between the inner and outer telescopic sections 2 and reduce the gap between the inner and outer telescopic sections. The friction between the expansion joints 2 ensures smooth expansion and contraction of the inner and outer ...

Abstract

The invention discloses a large-size construction equipment telescopic supporting leg convenient to insert and extract. The large-size construction equipment telescopic supporting leg comprises a pin shaft assembly, an outer telescopic joint and an inner telescopic joint. The outer telescopic joint and the inner telescopic joint are nested mutually to form a supporting leg body. The pin shaft assembly comprises a pin shaft and a handle arranged at the end of the pin shaft. The outer telescopic joint is provided with outer pin shaft holes for allowing the pin shaft to penetrate through. The inner telescopic joint is provided with inner pin shaft holes and a guide cylinder which are used for allowing the pin shaft to penetrate through. A pin shaft supporting device is further arranged at the outer pin shaft holes and is hollow pipeline. The pin shaft is arranged in the hollow pipeline of the supporting device. According to the large-size construction equipment telescopic supporting leg convenient to insert and extract, compared with the prior art, when needing to be inserted and extracted, the pin shaft only needs to be pulled and pushed in the pin shaft supporting device and the pin shaft holes and does not need to be manually lifted up to be inserted and extracted, and the labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of large-scale construction equipment, in particular to a telescopic outrigger for large-scale construction equipment that can be easily plugged in and out. Background technique [0002] In order to adapt to the slope of the erection line, large-scale construction equipment, especially the outriggers of the bridge erecting machine, widely adopt the outriggers of telescopic structure. By plugging and unplugging the pin shaft, adjusting the overlapping length of the telescopic joints nested together to realize the expansion and contraction of the outriggers, thereby adjusting the longitudinal posture of the bridge erecting machine. Due to the large tonnage of the bridge erecting machine, the pin shafts for insertion and extraction are large in diameter, long in length and heavy in weight, some weighing up to 90kg. When it comes to working at heights and space issues, often only one person can complete the plu...
