Please refer to fig. 3 to fig. 5, which can also be combined with fig. 8 and fig. 10. The flexible connecting mechanism 40 of the present application includes a connecting sleeve 41, a guide shaft 42 and an elastic member 43, the connecting sleeve 41 is fixed to the troweling plate 20, one end of the guide shaft 42 is fixed to the output end of the driving device 30, the guide shaft 42 slidably penetrates through the connecting sleeve 41, and the elastic member 43 is sleeved on the guide shaft 42 and elastically supported between the guide shaft 42 and the connecting sleeve 41. The elastic member 43 used in the present embodiment is a spring.

Referring to fig. 4, the plate body 21 and the first mounting seat 22 of the present embodiment are detachably connected, and of course, the first mounting seat 22 and the plate body 21 may be designed as an integral structure, which may be specifically selected according to production requirements or storage requirements.
Referring to fig. 3, 9 and 10, the troweling plate 20 further includes a fixing member 23, and the fixing member 23 is inserted into the connecting sleeve 41 from the side surface and passes through the first mounting seat 22. The connecting sleeve 41 is provided with a corresponding matching hole 412 (as shown in fig. 5), the fixing member 23 of this embodiment is a bolt, a screw of the bolt is inserted into the matching hole 412, and a nut can be used for screwing the screw onto the matching hole 412. Two bolts may be inserted through the side walls of the first mounting seat 22 and into the fitting holes 412, respectively. The connection of the connection sleeve 41 by the fixing member 23 can be maintained within a certain range in the first installation seat 22, and the connection sleeve 41 can be easily assembled. The term "a certain range" refers to the height of the connecting sleeve 41 that can be maintained in the first mounting seat 22, and it can be fixed or rotated, for example, the fixing member 23 is designed to be rotatable compared with the first mounting seat 22. The device can have a certain degree of freedom, but cannot float at a larger position in the vertical direction, so that the acting force can be normally transmitted.
Since the fixing member 23 can rotate relative to the first mounting seat 22, the guide shaft 42 can be moved to prevent stress concentration according to the driving force of the driving device 30 and the direction of the reaction force fed back from the base surface when the connecting sleeve 41 is engaged. Further, a bearing or the like may be disposed in the hole of the first mounting seat 22, so that the bolt may have a certain rotation capability after being inserted.
In this embodiment, the number of the first mounting seats 22 is two, and the two first mounting seats 22 are respectively connected to two ends of the plate body. In addition, the number of the driving devices 30 and the number of the flexible connecting mechanisms 40 are two, and the output ends of the two driving devices 30 are respectively flexibly connected with one first mounting seat 22 through one flexible connecting mechanism 40. Two first mount pads can avoid the both ends of plate body to produce swing about different in the lift in-process, avoid the swing to destroy the base face. By respectively configuring the driving device and the flexible connecting mechanism for each first mounting seat, the troweling plate can be quickly and stably reset to the working position when meeting obstacles.
Referring to fig. 1, fig. 2 and fig. 7, the frame 10 includes a frame body 11 and a second mounting seat 12, the troweling robot 1000 further includes a first connecting rod 13 and a second connecting rod 14, two ends of the first connecting rod 13 are respectively hinged to the first mounting seat 22 and the second mounting seat 12, two ends of the second connecting rod 14 are respectively hinged to the first mounting seat 22 and the second mounting seat 12, so that the first mounting seat 22, the second mounting seat 12, the first connecting rod 13 and the second connecting rod 14 form a parallelogram mechanism. By designing the parallelogram mechanism, the troweling plate 20 can move more smoothly upward than the second end. Wherein a first end of the driving device 30 is hinged to the second mounting seat 12. Since the driving device 30 is hinged with the second mounting seat 12, it can perform certain adjustment along with the relative movement between the first mounting seat 22 and the second mounting seat 12, so as to avoid being damaged by the reaction force during the process of adjusting the height of the troweling plate 20. Further, the first mounting seat 22 and the second mounting seat 12 extend vertically, and the first connecting rod 13 and the second connecting rod 14 are vertically spaced apart. By designing the extending directions of the first mounting seat 22 and the second mounting seat 12 and correspondingly setting the arrangement mode of the connecting rods, the driving device 30 can drive the troweling plate 20 to move vertically through the parallelogram mechanism.
The principle of the embodiment is as follows:
when the trowelling robot 1000 of the application works, the electric push rod pushes the first mounting seat 22 downwards, so that the trowelling plate 20 is abutted to the base surface of the ground, and the spring is compressed to a certain degree, so that the trowelling plate 20 can keep pressing the base surface to meet the pressure required by trowelling.
In this process, the flexible linkage 40 allows the drive mechanism 30 to maintain its inherent drive force, allowing the trowel plate 20 as a whole to be lifted upward and, after passing over an obstacle, to quickly return to its normal operating position, maintaining a pressure between the trowel and the base that meets the trowel requirements.
In the lifting process, the parallelogram mechanism is formed, so that the lifting process is smoother, the interaction between the trowelling plate 20 and the obstacles is further reduced, the trowelling plate 20 is not blocked integrally, the quality of trowelling construction is guaranteed, and equipment is prevented from being damaged.
To sum up, the floating plate 20 of this application floating device is connected with drive arrangement 30 through flexible connection mechanism 40 for drive arrangement 30 can enough be with floating plate 20 normal downward drive, support and hold ground, can make floating plate 20 again along with the in-process of frame 10 motion, meet the barrier and can be by barrier jack-up, damage in order to avoid floating plate 20, also can not destroy the base face because floating plate 20 blocks, can not cause floating robot 1000 self of using this floating device to be impaired simultaneously, effectively solved current problem.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
