Problems solved by technology

[0011] First, the central pump system is rigidly connected to the subframe and the hopper. When the whole machine is in use, the central pump inevitably participates in the stress deformation of the subframe, and there is a possibility of eccentric wear of the piston head, which reduces the wear resistance of the piston head. service life, increased maintenance costs
[0012] Second, welding deformation and other manufacturing errors in the production process make it difficult to assemble the hopper to the subframe. If forced assembly is used, the central pump will be deformed by force, and the piston head in the central pump will be eccent

Abstract

The invention discloses an elastic connecting device of a central pump system. The elastic connecting device comprises a secondary frame and the central pump system arranged on the secondary frame; the front and rear ends of the central pump system are hinged with the secondary frame through connecting shafts respectively, and a vibration damper is arranged at the hinged position; and the vibration damper comprises elastic shaft sleeves sleeved on the connecting shafts. The connecting device can effectively lighten piston head eccentric abrasion and vibration amplification of the central pumpsystem, and is easily assembled at the same time. The invention also discloses a concrete pump truck provided with the connecting device.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an elastic connection device for a central pump system of a concrete pump truck. The invention also relates to a concrete pump truck provided with said connecting device. Background technique [0002] With the rapid development of my country's economy, the large-scale and complex building structures have put forward higher and higher requirements for concrete machinery. [0003] Concrete pump truck is an engineering machinery with the function of pumping concrete, which is used to transport concrete to designated locations. Due to its many advantages and high economic benefits, it has become an indispensable special equipment for construction enterprises. [0004] The central pump system is an actuator that provides continuous power for pumping concrete, including hoppers, water tanks, and main pumping cylinders, etc. The hopper, also known as the collector, is a c...
