Embodiment Construction

[0018] Embodiments of the multi-stage luffing and telescopic foldable jib of the present invention:

[0019] The specific structure of the multi-stage luffing and telescopic foldable jib of the present invention is as follows: Figure 1 to Figure 5 As shown, it can be installed on the vehicle body 5 and use the vehicle body 5 as a carrier during use. When the foldable boom is in the fully retracted state, it meets the driving requirements of the vehicle lane. At this time, the structure is as follows: figure 2 with image 3 shown. When the foldable boom is fully extended, it meets the requirements of the use environment and working conditions. At this time, the structure is as follows: figure 1 shown.

[0020] Such as figure 1 As shown, the multi-stage amplitude-changing and telescopic foldable jib includes a first telescopic arm 1 and a second telescopic arm 2 , and also includes a first amplitude-changing mechanism 3 and a second amplitude-changing mechanism 4 . The f...

Abstract

The invention relates to a foldable arm frame with multistage amplitude changing and telescoping functions. Through arrangement of a second telescopic arm, under the premise that the height of a firsttelescopic arm is not decreased, the working amplitude and the amplitude changing angle of a whole arm frame system are increased. When the arm frame is unfolded, if the available space at the low altitude is limited, the included angle between the first telescopic arm and the horizontal plane can be increased through a first amplitude changing mechanism firstly, then all sections of arms in thefirst telescopic arm are controlled to extend out in sequence, then a second amplitude changing mechanism is controlled to increase the included angle between the second telescopic arm and the first telescopic arm, and finally, all sections of arms in the second telescopic arm are controlled to extend out in sequence, so that the foldable arm frame is completely unfolded. Therefore, through arrangement of the second amplitude changing mechanism, the space required for telescoping the foldable arm frame is reduced, and thus the foldable arm frame can achieve large amplitude changing in the small space.

Description

technical field [0001] The invention relates to a multi-stage amplitude-changing and telescoping foldable boom. Background technique [0002] Boom type equipment realizes amplitude and angle adjustment through variable amplitude. Due to height, space and use requirements, special equipment or certain equipment needs multiple continuous amplitude changes (such as aerial work vehicles, folding arm truck-mounted cranes, road and bridge inspection vehicles, Military UAV recovery equipment, etc.) and telescopic, at the same time due to the limited space size (such as vehicle driving and transportation, etc.). When it is necessary to meet the requirements of the national standard for road driving and to achieve large amplitude changes in a small space, it is often difficult to consider the dead point, torque, installation and stability, etc. Contents of the invention [0003] The object of the present invention is to provide a multi-stage zooming and telescoping foldable jib th...
