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...
