Embodiment Construction

[0050] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0051] The construction environment of concrete pump trucks is changing, and the single boom attitude and the single way of extending and retracting the boom have great limitations. figure 1 A schematic structural view of the deployment and retraction device for the boom in an embodiment of the present invention is schematically shown. Such as figure 1 As shown, in the embodiment of the present invention, a retractable device for a boom is provided, which is applied to construction machinery. The boom includes a plurality of boom sections connected to each other. The retractable device may include: an angle detector 102 , used to detect the angle of the boom s...

Abstract

The invention discloses an unfolding and folding device and method for an arm support and engineering machinery. The unfolding and folding device comprises an angle detector, a receiver and a controller, wherein the angle detector is used for detecting the angle of an arm section in the unfolding or folding process; the receiver is used for receiving an arm support unfolding instruction or an arm support folding instruction and receiving a preset arm support unfolding boundary or a preset arm support folding boundary; and the controller is configured to control the arm support to be unfolded or folded under the condition that the arm support unfolding instruction or the arm support folding instruction and the preset arm support unfolding boundary or the preset arm support folding boundary are received, obtain the angle of the arm section in the unfolding process or the folding process, determine the position of the tail end of the arm section according to the angle and the length of the arm section, determine the distance between the tail end of the arm section and the preset arm support unfolding boundary or the preset arm support folding boundary according to the position, compare the distance with a preset threshold value, and control the arm section to be unfolded to the target angle or folded to the initial state under the condition that the distance is larger than the preset threshold value. According to the unfolding and folding device and method for the arm support and engineering machinery, the labor cost can be reduced.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a retractable device for a boom, a retractable method and construction machinery. Background technique [0002] Concrete distributing equipment such as pump trucks, distributing machines, etc. is a commonly used construction machinery, which is used to transport concrete to a predetermined location through the delivery pipe on the boom. Before and after construction of this type of equipment, the operator needs to deploy and retract the boom according to the construction environment on site. This manual operation is time-consuming and laborious, and the safety and efficiency of the boom in the process of unfolding and retracting are affected by the proficiency of the operator. There is a problem of high labor cost. Contents of the invention [0003] The object of the present invention is to provide a retractable device, a retractable method and construction machinery for ...
