DETAILED DESCRIPTION

[0016] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0017] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0018] In a specific embodiment, Figure 1-2As shown, a top-hanging multifunctional mechanical arm for a railway integrated working vehicle comprises a manipulator mobile base 1, movable pulleys 2 corresponding to the guide rails are fixedly installed on both sides of the manipulator mobile base 1, a rotating base 3 is fixedly installed on the bottom of the manipulator mobile base 1, and an upper and lower telescopic rails 5 are fixedly installed on the output end of the rotating base 3, and a large arm rod 14 is fixedly installed on the telescopic end of the upper and lower telescopic rails 5, and the large arm rod 14 is rotatably connected to the large arm hydraulic cylinder 7, and one end of the large arm rod 14 and the large arm hydraulic cylinder 7 are both rotatably connected to the forearm fixed seat 8 to form a triangle or a quadrilateral, and the forearm fixed seat 8 is rotatably connected to the forearm hydraulic cylinder 9 and fixedly connected to the forearm rod 15, and the forearm hydraulic cylinder 9 and the forearm rod 15 are both rotatably connected to the movable wrist base 10, and a wrist rotating base 11 is fixedly installed on the movable wrist base 10, and a multifunctional bucket 13 is detachably fixedly installed on the driving end of the wrist rotating base 11.

[0019] In this embodiment, the number of movable pulleys 2 on the same side of the manipulator movable base 1 is not less than two, the guide rail is fixed above the rail, the movable pulley 2 is located in the slide rail, and the slide rail contacts the top and bottom of the movable pulley 2 to limit the up and down jumping of the movable pulley 2 and prevent the movable pulley 2 from detaching from the guide rail.

[0020] In this embodiment, it also includes a fixed base rotation hydraulic motor 4, which is transmission-connected to the rotating base 3 to drive the output end of the rotating base 3 to rotate. A motor is fixedly installed in the wrist rotating base 11, and the motor drives the output end of the wrist rotating base 11 to rotate.

[0021] In this embodiment, the upper and lower telescopic rails 5 are electric telescopic rails, and a boom fixing seat 6 is fixedly installed at the telescopic end of the upper and lower telescopic rails 5, one end of the boom rod 14 is fixedly connected to the boom fixing seat 6, and the boom hydraulic cylinder 7 is rotatably connected to the boom fixing seat 6. The boom fixing seat 6, the boom hydraulic cylinder 7, the forearm fixing seat 8 and the boom rod 14 form a quadrilateral with fixed angles, so that the boom hydraulic cylinder 7 rotates the angle of the forearm fixing seat 8 when telescoping.

[0022] The forearm hydraulic cylinder 9, forearm rod 15, forearm fixing seat 8 and movable wrist base 10 form a quadrilateral with fixed angles. When the forearm hydraulic cylinder 9 is extended or shortened, it drives the movable wrist base 10 to rotate, thereby driving the multifunctional bucket 13 to flip.

[0023] In this embodiment, the wrist rotating base 11 and the multifunctional bucket 13 are detachably fixedly connected through the bucket quick-change pin 12, so as to facilitate the replacement of the multifunctional bucket 13 with different functions or sizes. Furthermore, the bucket quick-change pin 12 is a bolt and there are multiple of them. The bucket quick-change pin 12 penetrates the multifunctional bucket 13 from the inside of the multifunctional bucket 13 and is threadedly connected to the driving end of the wrist rotating base 11 to fix the wrist rotating base 11 and the multifunctional bucket 13.

[0024] According to actual needs, the above-mentioned top-hanging multifunctional mechanical arm for railway integrated operation vehicle can be further optimized and / or improved:

[0025] The axis of the upper and lower telescopic rails 5 coincides with the axis of the rotation of the driving end of the rotating base 3. When the rotating base 3 drives the upper and lower telescopic rails 5 to rotate, the upper and lower telescopic rails 5 rotate by themselves, so that the multifunctional bucket 13 moves in a circle, which makes it easier to calculate the trajectory and facilitates the realization of automated control.

[0026] When in use, the moving pulley 2 controls the multi-functional bucket 13 to move linearly in the horizontal direction, and the angle of the multi-functional bucket 13 in the horizontal direction is controlled by rotating the rotating base 3. The upper and lower telescopic rails 5 can control the movement of the multi-functional bucket 13 in the vertical direction. The upper arm hydraulic cylinder 7 and the lower arm hydraulic cylinder 9 can control the flipping angle of the multi-functional bucket 13. The wrist rotating base 11 can control the direction of the multi-functional bucket 13, so that the multi-functional bucket 13 has multi-axis degrees of freedom and can realize more functions.

[0027] To sum up: the multifunctional bucket 13 can rotate horizontally, flip over, and move up and down, forward and backward, so that the multifunctional bucket 13 can be constructed along the railway track, assisting manual labor in carrying equipment, turning and paving ballast, moving sleepers and other operations, increasing functionality, replacing manual labor to complete more tedious or more difficult gravity carrying and other tasks, improving work efficiency and saving labor costs.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
