Technical Field
[0001] The utility model relates to the technical field of aerial work vehicles, in particular to a rotating device of an aerial work vehicle. Background Art
[0002] The components of a traditional aerial work vehicle include a base, a lifting device and a workbench. There are great limitations in the operation of such an aerial work vehicle. For example, the workbench and the lifting device are fixedly connected and cannot rotate, which often causes the embarrassment of insufficient distance during aerial work. The existing aerial work vehicle rotating device allows the work platform and the lifting and lowering device to rotate freely by setting a driven gear, a driving gear, and an arc-shaped slide rail, thereby reducing the distance limitation of aerial work, making the operation more convenient and quick, and the use more stable and safe.
[0003] However, the working platform of the existing aerial work vehicle still rotates around the center as the axis after performing left and right linear motion, resulting in the extension of the rotating arm due to the left and right movement of the working platform and the expansion of the rotation angle, resulting in inaccurate movement. After searching, it was found that the technical solution provided by the utility model with application number CN201720944472.1 also has the above-mentioned problems. Summary of the invention
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a rotating device for an aerial work vehicle. By arranging a first motor, a threaded rod, a slider, a mounting block, and a second motor, the rotation center of the working platform body moves with its own translation, and the rotating arm length remains unchanged to make the rotation more precise. By arranging a fixed plate, a limit block, a pull rod, and a spring, the positive angle of the platform is locked and limited, and manual operation is required to continue turning, which serves to remind the staff of the angle.
[0005] To achieve the above-mentioned purpose, the utility model also provides a rotating device of an aerial work vehicle, including: a base, a slide rail is fixedly connected to the upper surface of the base, a first motor is fixedly connected to the outer surface of the slide rail, a threaded rod is fixedly connected to the output end of the first motor, a slider is threadedly connected to the outer surface of the threaded rod, a mounting block is fixedly connected to the upper surface of the slider, a second motor is fixedly connected to the inner surface of the mounting block, and a working platform body is fixedly connected to the output end of the second motor. By arranging the first motor, the threaded rod, the slider, the mounting block, and the second motor, the rotation center of the working platform body moves with its own translation, and the rotation arm length remains unchanged to make the rotation more precise.
[0006] The inner surface of the working platform body is fixedly connected with a fixed plate, the upper surface of the fixed plate is movably connected with a limit block, the lower surface of the limit block is fixedly connected with a pull rod, the lower surface of the pull rod is fixedly connected with a resistance block, and the upper surface of the resistance block is fixedly connected with a spring. By arranging the fixed plate, the limit block, the pull rod and the spring, the positive angle of the platform is locked and limited, and manual operation is required to continue turning, which serves to remind the staff of the angle.
[0007] According to the rotating device of the aerial work vehicle, the outer surface of the threaded rod is rotatably connected to the slide rail, and the outer surface of the first motor is fixedly connected to the base.
[0008] The outer surface of the sliding block is slidably connected to the sliding rail, and the lower surface of the mounting block is slidably connected to the sliding rail.
[0009] The lower surface of the working platform body is rotatably connected to the mounting block, and the lower surface of the working platform body is movably connected to the base.
[0010] The outer surface of the pull rod is slidably connected to the fixing plate, and one end of the spring away from the abutment block is fixedly connected to the fixing plate.
[0011] The outer surface of the abutment block is movably connected to the base.
[0012] A slide groove is arranged on the lower surface of the resistance block, and the inner surface of the slide groove is movably connected with the base. When the working platform body rotates to the starting angle, the restoring force of the spring causes the slide groove to be clamped into the base.
[0013] The first motor and the second motor are both electrically connected to an external power source.
[0014] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
