Here, the plurality of road wheels 51 may be parallel or non-parallel. Illustratively, the plurality of road wheels 51 are evenly distributed along the ring. Thus, the working part 411 of the wall grinding robot is positioned at the center of the plurality of traveling wheels 51, and traveling accuracy and positioning accuracy are high. The number of the traveling wheels 514 is determined according to the actual design requirements, and the form thereof is also rich, including the types of common moving wheels, universal wheels, omni wheels and the like.

In case the wall milling robot comprises a second housing 6, in some embodiments the walking means 5 is arranged inside the second housing 6, the walking means 5 being connected to the first housing 1 through the second housing 6. An annular cavity is formed between the first shell 1 and the second shell 6, and the running gear 5 is positioned in the annular cavity. Thus, the wall surface grinding robot has better integrity, and the walking device 5 can be well protected by the second shell 6.
Referring to fig. 1-5 in combination, in some embodiments, the wall surface grinding robot further includes a sensor 71 and a holder 72. The sensor 71 is electrically connected to the vacuum cleaner 3, and when the sensor 71 is triggered, the sensor 71 generates a start-stop signal to the vacuum cleaner 3, wherein the start-stop signal is configured to drive the vacuum cleaner 3 to start or stop. Exemplarily, the start-stop signal is an electrical signal, and the vacuum cleaner 3 changes the start-stop state upon receiving the start-stop signal. The sensor 71 is illustratively a contact sensor or a non-contact sensor, typically a contact sensor such as a micro-switch, a pressure sensor, etc., and typically a non-contact sensor such as a photo sensor, etc.
The holder 72 is slidably disposed on a side of the first back side 1B of the first housing 1 away from the first working side 1A, and the holder 72 slides to contact or non-contact trigger the start/stop signal of the sensor 71. Exemplarily, the holding member 72 is disposed on a side surface of the first casing 1 away from the wall surface, and there is relative sliding between the holding member 72 and the first casing 1. In operation, the operator pushes the holder 72 to move the holder 72 on the first housing 1. The structure of the holder 72 may be various, such as a grip handle, a grip ring, etc.
Between the holder 72 and the first housing 1, a reset element 8 is provided, in some embodiments, the reset element 8 is configured to restore the holder 72 to an initial position. The restoring element 8 is exemplarily an elastic element, and a common type thereof is various types of springs capable of outputting an elastic force, such as a tension spring, a compression spring, and the like.
Under the push of the operator, the holder 72 slides and thus triggers the start-stop signal of the sensor 71 in a contact or non-contact manner. When the operator releases his hand, the reset element 8 resets the sliding movement of the handle 72 in the opposite direction. Under the touch trigger, the holding piece 72 touches the touch sensor 71, and the touch sensor 71 sends out an electric signal (i.e. a start-stop signal) under the touch action and outputs the electric signal to the negative pressure dust collector 3; under the non-contact triggering, the holding piece 72 enters the sensing range of the non-contact sensor 71, and the non-contact sensor 71 senses and sends out an electric signal (i.e. a start-stop signal) and outputs the electric signal to the vacuum cleaner 3.
Exemplarily, the number of the holding pieces 72 is two, and the holding pieces are respectively held by two hands of an operator, so that the operation convenience and reliability are improved. The ends of the two holding pieces 72 are connected through a connecting piece 9, so that the movement synchronism is kept. The connection 9 triggers the start-stop signal of the sensor 71 in a contact or contactless manner. Illustratively, the two holding members 72 are parallel to each other to facilitate handling.
The sliding direction of the holding member 72 can be designed according to the actual requirement, and the invention is not limited to this. In some embodiments, the holding member 72 slides linearly along the axial direction of the elastic pressing ring 2, and when the holding member 72 slides to the end of the stroke in the direction close to the working side, the holding member 72 causes the sensor 71 to send a start-stop signal. When the robot is used for climbing a wall, an operator only needs to hold and push the holding piece 72 to slide along the direction close to the wall surface, so that the wall-climbing robot can reliably cling to the wall surface and the negative pressure dust suction device 3 is started, thereby achieving two purposes and greatly improving the operation convenience and efficiency.
Exemplarily, when the sensor 71 is located inside the first housing 1, the end of the holder 72 slidingly passes through the sidewall of the first housing 1 to perform contact or non-contact triggering of the sensor 71.
In case the wall milling robot comprises a second housing 6, in some embodiments the holding piece 72 is slidably arranged at a side of the second back side 6B of the second housing 6 facing away from the second working side 6A, and the reset element 8 is arranged between the holding piece 72 and the second housing 6. Furthermore, the first housing 1 is connected to the restoring element 8 via the second housing 6.
Illustratively, when the sensor 71 is located inside the second housing 6, the distal end of the holder 72 slidingly passes through the side wall of the second housing 6 for contact or contactless triggering of the sensor 71. Exemplarily, the second housing 6 has a concave portion 61 corresponding to the holding member 72, and the concave portion 61 is concave along the direction approaching the wall surface, so as to provide a holding space for an operator and a movement space for pushing the holding member 72 to slide, thereby improving the holding comfort and safety and preventing the operator's hand from being damaged.
In some embodiments, the grinding apparatus 4 includes a grinding head 41 configured to perform a grinding action, and a driving device 42 for driving the grinding head 41 to operate, the grinding head 41 being disposed in the first internal cavity 11 and having a working portion 411. The drive means 42 may be of the type of a drive motor, hydraulic motor or the like.
In some embodiments, the sanding head 41 is a sanding disc, the side of the sanding disc remote from the first back side 1B being configured as a working portion 411. The working part 411 directly contacts the wall surface, thereby polishing the uneven portion of the wall surface. Exemplarily, the grinding disc has a chip removal hole 412 penetrating therethrough along the first direction, one end of the chip removal hole 412 is opened at a side of the grinding disc close to the working side, and the other end is opened to communicate with the vacuum cleaner 3. Like this, negative pressure dust extraction 3 can be through chip removal hole 412, in time siphons away the abrasive dust dregs that will produce at the in-process of polishing and avoid taking place the waste material and pile up, and the first aspect can avoid polishing head 41's the operation of polishing to receive the interference, and on the other hand can in time dispel the heat and cool down, prevents polishing head 41's the temperature sharp rising and suffer the harm, and the third aspect can prevent to take place the dust and reveal, guarantee the clean environmental protection of operation process.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
