A boom system for a wheeled wet spraying machine

Abstract

The invention provides a boom system for a wheel type wet sprayer. The boom system for the wheel type wet sprayer comprises a rotary table arranged on a machine tool, and a boom device connected with the rotary table, wherein the rotary table is of a bilateral symmetry structure and comprises a rotary chassis, two vertical support plates and a horizontal support plate; a first through hole and a second through hole are respectively formed on the same height in the top parts of the vertical support plates; a third through hole is formed in the center of the horizontal support plate; the central points of the first through hole, the second through hole and the third through hole are located on the same vertical face; the tail end of a big arm and the rotary table are hinged at the first through hole and the second through hole; the front end of the big arm is hinged to the tail end of a small arm through two connecting rods; vertices of a quadrangle formed by one section of the front end of the big arm, one section of the tail end of the small arm and the two connecting rods are respectively located in a vertical face where the central axis of the big arm and the central axis of the small arm are jointly located. According to the boom system for the wheel type wet sprayer, the eccentric load phenomenon of all axle sleeves at hinged points is avoided, and the deformation of axle sleeve holes in the hinged points is controllable and uniform, so that the service life of a boom assembly and even the service life of the whole concrete wet spraying machine are improved.

Description

technical field [0001] The invention relates to the technical field of wheeled wet spraying machines, in particular to an arm support system for wheeled wet spraying machines. Background technique [0002] In the concrete wet spraying machine industry, the bottom of the turntable assembly is connected with the frame assembly or chassis assembly, and the upper part is connected with the arm frame assembly or the placing boom. In the actual construction process, the whole machine is fixed at a certain place on the construction site. When the construction area is large, the position of the concrete nozzle needs to be adjusted. There are several ways to adjust the nozzle action: 1. Adjust the position of the whole machine, which is time-consuming and laborious, which seriously affects the construction efficiency; 2. Rotate the turntable assembly and adjust the height and expansion of the boom, which is efficient and convenient. However, when the second method is adopted, comple...
