Problems solved by technology

Due to the structural limitations of the above-mentioned boom device, for large-scale long-boom pump trucks, the boom needs to have a very long span. Under the limitation of the number of boom sections, the length of the single-section boom needs to be set longer, thus causing the pump The total length of the vehicle is too long, which is not conducive to the driving of the pump truck

Embodiment Construction

[0024] The specific implementation manners according to the present invention will be described below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, therefore, the present invention is not limited to the specific embodiments disclosed below limit.

[0026] figure 2 A schematic top view of the folded state of the boom device with five-section boom according to the first embodiment of the present invention is shown.

[0027] Such as figure 2 As shown, the boom device provided by the present invention includes at least three booms hinged head-to-tail in sequence. The boom device has a folded state and an unfolded state. In the folded state, the second boom 2 is folded on the first boom 1 above, and each section of the jib is distributed on the first l...

Abstract

A beam device comprises at least three sections of beams hinged end to end in turn. When the beam device is in a folded state, a second section of beam (2) is folded on the top of a first section of beam (1), and the beams are distributed on a first longitudinal surface (01), a second longitudinal surface (02) and a third longitudinal surface (03) paralleled with and spaced from each other. The second longitudinal surface (02) is located between the first longitudinal surface (01) and the third longitudinal surface (03). At least two sections of beams extend respectively between the first longitudinal surface (01) and the second longitudinal surface (02), and between the second longitudinal surface (02) and the third longitudinal surface (03). A concrete pump vehicle is provided with said beam device. The beam device can be provided with more beams to expand the beam spread of the beam device without increasing the length and the width of the vehicle. Under identical beam spread, the quantity of the beams can be increased so as to reduce the length of a single section of beam.

Description

technical field [0001] The invention relates to an arm support device for engineering machinery. At the same time, the invention also relates to a concrete pump truck comprising the boom device. Background technique [0002] At present, a concrete pump truck generally includes a traveling device, a pumping device and a boom device. The walking device is mainly used for the transfer of the working site of the concrete pumping equipment, and the pumping device and the boom device are mainly used for transporting concrete to the place where concrete is needed during the construction process. [0003] The boom device commonly used for concrete pump trucks consists of a multi-section boom and a boom cylinder that drives the boom to fold. Driven by hydraulic oil, the boom cylinder moves to fold or unfold the multi-section boom. [0004] At present, there are many folding methods for the boom device, which can be divided into R (winding) type, Z (folding) type and RZ comprehensiv...
