Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4 This utility model provides an electric cylinder-driven two-section telescopic arm mechanism, including a support base 100, a robotic arm 200, a mounting component 300 that provides a mounting base for a high-pressure rotary washer, and a driving component 400 for driving the robotic arm 200 to perform telescopic operations. The robotic arm 200 is located on the top of the support base 100, the mounting component 300 is located at the free end of the robotic arm 200, and the driving component 400 is located on the support base 100. The robotic arm 200 includes a telescopic arm 210 movably connected to the top of the support base 100, a second telescopic arm 220 located at the end of the first telescopic arm 210 away from the support base 100, a connecting component 230 between the first telescopic arm 210 and the second telescopic arm 220, the mounting component 300 located at the end of the second telescopic arm 220 away from the connecting component 230, and the driving component 400 located between the support base 100 and the first telescopic arm 210.
[0026] One section of telescopic arm 210 includes a main telescopic arm A211 and an auxiliary telescopic arm A212 arranged vertically. A shaft A213 is fixedly connected to the end of the main telescopic arm A211 and the auxiliary telescopic arm A212 away from the connector 230. Both ends of the shaft A213 are rotatably connected to the top of the support base 100 through a rotating shaft. The drive unit 400 is located between the main telescopic arm A211 and the support base 100.
[0027] The two-section telescopic boom 220 includes a main telescopic boom B221 and an auxiliary telescopic boom B222 arranged vertically. A shaft B223 is fixedly connected to the end of the main telescopic boom B221 and the auxiliary telescopic boom B222 away from the connector 230. The mounting member 300 is movably connected to the two shafts B223. The connector 230 is movably located between the main telescopic boom B221, the auxiliary telescopic boom B222, the main telescopic boom A211, and the auxiliary telescopic boom A212.
[0028] The connector 230 includes four shafts C231, which are rotatably connected to one end of the main telescopic arm A211, the auxiliary telescopic arm A212, the main telescopic arm B221, and the auxiliary telescopic arm B222 via rotating shafts. A side plate 232 is provided on one side of the main telescopic arm A211, and the end of the shaft C231 is rotatably connected to the side plate 232 via rotating shafts. A linkage is provided between the shaft C231 at the end of the main telescopic arm B221 and the shaft C231 at the end of the auxiliary telescopic arm B222. The connector 230 enables the first telescopic arm 210 and the second telescopic arm 220 to move away from each other using a parallelogram linkage, so that the first telescopic arm 210 and the second telescopic arm 220 can operate synchronously without the use of a drive device, thereby realizing the telescopic operation of the first telescopic arm 210 and the second telescopic arm 220.
[0029] Among them, shafts C231, B223 and A213 are arranged in parallel to each other.
[0030] The linkage includes a connecting rod A233 fixedly connected to the shaft C231 at the end of the main telescopic boom A211. The other end of the connecting rod A233 is rotatably connected to a V-shaped rod 234 via a rotating shaft. A connecting rod B235 is fixedly connected to the shaft C231 at the end of the auxiliary telescopic boom B222. The connecting rod B235 is rotatably connected to the end of the V-shaped rod 234 away from the connecting rod A233 via a rotating shaft. The linkage enables the two telescopic booms 220 to operate synchronously when one telescopic boom 210 is in operation.
[0031] The mounting component 300 includes a support plate 310 located on the top of the main telescopic arm B221 away from the connecting rod B235. A support plate 320 is fixedly connected to both sides of the bottom of the support plate 310. The two ends of the shaft B223 are rotatably connected between the two support plates 320 through a rotating shaft. The mounting component 300 can provide a mounting base for the high-pressure rotary cleaner, so that when the robotic arm 200 moves the mounting component 300, it can move the high-pressure rotary cleaner synchronously to adjust the operating position of the high-pressure rotary cleaner.
[0032] The drive unit 400 includes a boss A410 fixedly connected to the support base 100. A servo cylinder 420 is rotatably connected to the boss A410 via a rotating shaft. The output end of the servo cylinder 420 passes through the inner cavity of the auxiliary telescopic arm A212 and the main telescopic arm A211 and extends to the top of the main telescopic arm A211. The output end of the servo cylinder 420 is rotatably connected to a boss B430 via a rotating shaft. The boss B430 is fixedly connected to the top of the main telescopic arm A211 near the shaft A213. By activating the servo cylinder 420, the output end of the servo cylinder 420 can drive the robotic arm 200 and the mounting component 300 to operate through the boss B430. The stroke setting of the boss A410 can precisely control the position of the positioning working surface.
[0033] The working principle of this utility model is as follows: A high-pressure rotary cleaner is installed on the pallet 310. During cleaning operations, the cam A410 is activated, and the output end of the servo cylinder 420 drives the cam B430 to move. The cam B430 drives the main telescopic arm A211 to rotate around its shaft A213. The main telescopic arm A211 drives its shaft C231 and connecting rod A233 to move synchronously. The shaft C231 on the main telescopic arm A211 drives the side plate 232 to move, and the side plate 232 drives the other three shafts C231 to move synchronously. This results in a parallelogram-like structure formed between the support base 100, the main telescopic arm A211, the auxiliary telescopic arm A212, and the side plate 232. The mounting component 300, the main telescopic arm B221, and the auxiliary telescopic arm B22... 2. A parallelogram-like structure is formed between the auxiliary telescopic arm A212, the main telescopic arm B221, and the auxiliary telescopic arm B222, so that the auxiliary telescopic arm A212, the main telescopic arm B221, the auxiliary telescopic arm B222, and the mounting component 300 can all adopt the parallelogram linkage restriction principle, so that the auxiliary telescopic arm A212, the main telescopic arm B221, the auxiliary telescopic arm B222, and the mounting component 300 move synchronously with the main telescopic arm A211. The shaft C231 on the main telescopic arm A211 and the side plate 232 also drive the connecting rod A233, the V-shaped rod 234, and the connecting rod B235 to move synchronously, so as to adjust the included angle between the first telescopic arm 210 and the second telescopic arm 220, thereby making the mounting component 300 gradually move closer to or away from the support base 100 for position adjustment, so that the high-pressure rotary cleaner is accurately positioned to meet the requirements of working surface cleaning.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
