Problems solved by technology

Due to the large volume and weight of the boom device itself, this horizontal rotation method has a large inertia, which not only increases the energy consumption of the pump truck, but also has an adverse effect on the service life of the entire boom
[0004] In the existing boom device, the relative movement between all the booms is limited to the rotation in the vertical plane, which limits the movement trajectory of the boom, affects the flexibility of the concrete pump truck, and has a dead point in the distribution, which affects the construction efficiency

Abstract

The invention provides an arm support structure, which comprises a first arm section and a second arm section, wherein the first arm section and the second arm section are connected by a spindle; a hinged axis of the spindle and the end part of the arm support structure is vertically arranged; a driving device and a first driving wheel are installed on the first arm section; a second driving wheel can be rotatably installed on the spindle; the second arm section and the second driving wheel are fixedly connected; each of the first driving wheel and the second driving wheel is respectively provided with a driving mechanism; the driving device drives the first driving wheel to rotate; and the first driving wheel drives the second driving wheel and the second arm section to rotate around the spindle by the driving mechanism. The invention also provides an arm support device and a concrete pump truck. According to the technical scheme provided by the invention, a function that the arm support horizontally rotates is realized, and the cloth flexibility is increased.

Description

technical field [0001] The invention relates to the field of engineering machinery, and more specifically, relates to a boom structure, a boom device with the boom structure and a concrete pump truck with 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 concrete pumping equipment in the work site, and the pumping device and boom device are mainly used for transporting concrete to the place where concrete is needed during the construction process. [0003] The boom device consists of multi-section booms hinged in sequence. The two adjacent booms mainly rotate in the vertical plane, and horizontal rotation cannot be realized; if horizontal rotation is required, the slewing bearing can only be driven by the slewing motor and reducer. To drive the turntable to rotate, so as to realize the horizontal rotation of the boom...
