Abstract

The invention discloses an arm rest auxiliary supporting device and a pump car with the arm rest auxiliary supporting device. The arm rest auxiliary supporting device comprises an upper connecting frame, a rolling wheel, a bottom frame and a spring, wherein the rolling wheel is arranged on the upper connecting frame and is used for providing auxiliary supporting for an arm rest; the upper connecting frame is sleeved with the bottom frame, and the upper connecting frame can vertically slide relative to the bottom frame; and the spring is arranged between the upper connecting frame and the bottom frame and is used for providing elastic supporting force for the upper connecting frame. The arm rest auxiliary supporting device can adjust height by itself, and is in elastic contact with an arm rest assembly, and therefore the arm rest assembly can be effectively supported; the consistency of the arm rest auxiliary supporting device is good, and the phenomenon that a support is too high, and consequently, an arm rest deforms, or the support is too short, and consequently, a gap exists between the support and the arm rest is avoided. The final height of the arm rest auxiliary supporting device is adjusted without fit welding of an assembly field, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to an auxiliary supporting device for a boom and a pump truck with the same. Background technique [0002] The boom is one of the main components of construction machinery such as pump trucks. see figure 1 , in the stowed state, the jib assembly 200 is usually supported by the jib main support 400 and the jib auxiliary support 100 . The main support of the boom is installed on the chassis 300 of the pump truck, supports the main weight of the boom assembly 200, and provides left and right limits to prevent the boom from shaking left and right when the vehicle turns. The boom auxiliary support 100 is also installed on the bottom frame 300 of the pump truck for providing auxiliary support to the boom assembly 200 to prevent or reduce the deflection of the boom. [0003] see figure 2 , the boom auxiliary support in the prior art generally includes an upper bracket 1...
