Abstract

The invention discloses a boom supporting structure and a pump truck having the same. The boom support structure includes a boom main support and a boom auxiliary support device. The boom auxiliary support device includes: an upper connecting frame; rollers, which are arranged on the upper connecting frame, to provide auxiliary support for the boom; a bottom frame, which is sleeved with the upper connecting frame, and the upper The connecting frame can slide up and down relative to the bottom frame; and a spring, which is arranged between the upper connecting frame and the bottom frame, is used to provide elastic support for the upper connecting frame. The boom auxiliary support device of the present invention can adjust the height by itself, and is in elastic contact with the boom assembly, so as to realize effective support for the boom assembly, the consistency of the product is good, and avoid the deformation of the boom caused by the bracket being too high Or the bracket is too short to cause a gap between the bracket and the boom. In addition, there is no need to adjust the final height of the auxiliary support device of the arm frame by welding on the assembly site, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a boom support structure and a pump truck having 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 112 , a lower bra...
