Description

Technical Field

[0001] The utility model relates to the technical field of large-scale train maintenance, and in particular to a precision-adjustable maintenance assisting manipulator. Background Art

[0002] Large trains, including trains and subways, require regular and detailed maintenance to ensure safe and efficient operation due to their large size and complex mechanical structure. These maintenance works are usually carried out in specially designed tunnels under the tracks. During the maintenance process, workers often need to disassemble key components on the train, and this process often involves using a handheld wrench to loosen or remove the bolts fastened to the components.

[0003] However, due to the certain height difference between the lower part of the train and the tunnel floor, when it is necessary to dismantle parts located higher up in the train, the staff have to lift the wrench to a fairly high position to operate. Such operation not only increases the operating burden of the staff, but also aggravates the difficulty and risk of the operation. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 As shown, a precision-adjustable maintenance assisting manipulator comprises a maintenance vehicle 1, wherein the maintenance vehicle 1 is provided with a power source for driving a power motor 307 and a force sensing handle 5;

[0021] The maintenance vehicle 1 further includes a power assist assembly 3, which includes a fixing seat 301, a servo electric cylinder 302 disposed on the fixing seat 301, a loading plate 303 disposed on the top of the servo electric cylinder 302, a first folding arm link 304 disposed on the loading plate 303, and a second folding arm link 305 disposed at one end of the first folding arm link 304. The loading plate 303, the first folding arm link 304, and the second folding arm link 305 are movably connected through a low-damping joint 306. The power motor 307 for driving the servo electric cylinder 302 is mounted on the fixed seat 301, and the force sensing handle 5 and the hydraulic wrench group 6 are arranged on the second folding arm connecting rod 305, and the force sensing handle 5 is electrically connected to the power motor 307. The servo electric cylinder 302 can drive the loading plate 303 to move up and down. The first folding arm connecting rod 304 and the second folding arm connecting rod 305 can support the weight of the hydraulic wrench group 6, so as to help the staff to lift the maintenance tools, reduce the labor intensity of the staff, and can be folded when not in use. The folding arm link 304 and the second folding arm link 305 are bent and stored, and will not occupy a large space in the tunnel, reserving space for other operations of the staff. When the operator holds the force sensing handle 5, the force sensing handle 5 sends a corresponding signal by detecting the upward or downward operating force of the operator. After the power motor 307 receives the signal fed back by the force sensing handle 5, it drives the servo electric cylinder 302 after calculation and transformation, thereby realizing the follow-up lifting and lowering of the loading plate 303, so that the first folding arm link 304 and the second folding arm link 305 can be loaded with the hydraulic wrench group 6 for movement. The greater the operator's operating force, the faster the first folding arm link 304 and the second folding arm link 305 move, which greatly facilitates the staff to adjust the height of the hydraulic wrench group 6 in the narrow tunnel. The low damping joint 306 can withstand axial and radial loads, so that the hydraulic wrench group 6 can obtain gravity balance support while still being able to move flexibly on the horizontal plane, facilitating bolt disassembly and assembly operations.

[0022] In this embodiment, specifically, a base rib plate 2 for forming a fixed connection with the power assist assembly 3 is provided on the maintenance vehicle 1. The provided base rib plate 2 enables the power assist assembly 3 to be firmly fixed on the maintenance vehicle 1, thereby ensuring stability during subsequent work.

[0023] In this embodiment, specifically, a fixed vertical plate 308 is provided on the opposite side of the base rib plate 2, and a guide telescopic plate 309 is provided on each group of fixed vertical plates 308. A support plate 310 is provided on the guide telescopic plate 309, and the support plate 310 is connected to the loading plate 303. The fixed vertical plates 308 are set to mount the guide telescopic plates 309 on the base rib plate 2. When the loading plate 303 is raised or lowered, the guide telescopic plates 309 perform telescopic movement therewith, which can guide the movement of the loading plate 303, and provide stable and reliable guide support for the hydraulic wrench group 6 when working, to avoid shaking and damaging the force sensing handle 5 or the servo electric cylinder 302.

[0024] In this embodiment, specifically, two groups of buffer pads 311 are provided on the loading plate 303 to support the first folding arm link 304 , and the buffer pads 311 are made of elastic material, which provides good support for the movement of the first folding arm link 304 and the second folding arm link 305 .

[0025] In this embodiment, specifically, a fine-tuning member 4 which is movably connected to the hydraulic wrench group 6 is provided on the second folding arm connecting rod 305, so that during the process of disassembling and assembling bolts, the hydraulic wrench group 6 can have a certain movable space in the height direction, which is convenient for fine-tuning.

[0026] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
