Problems solved by technology
[0002] At present, most of the folding booms attached to high-altitude operation equipment are single-degree-of-freedom rotation functions. When performing high-altitude operations, the single-degree-of-freedom movement boom needs to rotate the turntable or move the entire equipment position when it encounters a small adjustment of the working position. It is cumbersome and sometimes cannot achieve the desired job position
A few booms also have two-degree-of-freedom rotation, but they use a swing cylinder and a hydraulic cylinder to achieve two-degree-of-freedom rotation. The swing cylinder is currently relatively expensive, which leads to an increase in the total cost

Embodiment Construction
[0013] Such as figure 1 As shown, the platform support 1 of the space double-degree-of-freedom swing folding arm frame is connected to the main boom frame 12 through the connecting pin 3, the platform support 1 is hinged with the working platform leveling cylinder 10 through the hinge hole below it, and the working platform is adjusted The other end of the flat cylinder 10 is hinged on the main boom 12, and the bottom surface of the working platform is always level by the thrust of the working platform leveling cylinder 10. The parallel link mechanism of the space double-degree-of-freedom swing folding arm frame is composed of the cardan shaft 2, the connecting pin shaft 3, four parallel connecting rods 4, and four hinge shafts 6. The two ends of the four parallel connecting rods are supported by the platform support. 1. The hole of the swing cylinder 5 and the lock nut 7 are fixed, the hinge shaft 6 is connected to one of the cardan shafts 2, and the connecting pin shaft 3 is...

The invention discloses a spatial dual-degree of freedom (DOF) swinging articulated boom support, which relates to a rotary arm support matched with an aloftwork device. In the invention, a spatial parallel linkage consists of a spatial kinematic pair with dual rotating degrees of freedom, and is characterized by utilizing a driving oil cylinder to drive a connecting rod to rotate on the basis of a geometric principle that two opposite sides are always parallel and equal, i.e. an X-axis rotary oil cylinder is connected to parallel connecting rods, when the X-axis rotary oil cylinder extends, the parallel connecting rods can be driven; when a Y-axis rotary oil cylinder extends, the parallel connecting rods can be driven, and one of the connecting rods is driven to rotate so as to drive the other connecting rod of the parallel linkage to rotate along with the connecting rod; two ends of the Y-axis rotary oil cylinder are connected with hinged holes on the two connecting rods; and the X-axis rotary oil cylinder is hinged on a cardan shaft through a hinged shaft, the cardan shaft is arranged at a hinged shaft on a platform support and a hinged shaft of an oscillating oil cylinder. In this way, the multi-DOF rotation of the swinging articulated boom support is achieved, and the motion range and micro-adjustment range of the swinging articulated boom support are enlarged.
Description
technical field [0001] The invention relates to a rotating and folding arm frame matched with high-altitude operation equipment, in particular to a folding arm frame with dual-degree-of-freedom rotating motion in space. Background technique [0002] At present, most of the folding booms attached to high-altitude operation equipment are single-degree-of-freedom rotation functions. When performing high-altitude operations, the single-degree-of-freedom movement boom needs to rotate the turntable or move the entire equipment position when it encounters a small adjustment of the working position. It is cumbersome and sometimes cannot reach the desired job position. A few booms also have two degrees of freedom rotation, but the swing cylinder and a hydraulic cylinder are used to realize the two degrees of freedom rotation. The swing cylinder is currently relatively expensive, which leads to an increase in the total cost. Contents of the invention [0003] The purpose of this pa...
