Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] The present invention provides a wheeled tree climbing robot through improvement. The technical solution of the present invention is:

[0040] Through the above structure, the electric telescopic rod 301, the pressure sensor 306 and the push plate 302 are used to effectively fit and grasp trees of different diameters. At the same time, the pressure can be automatically adjusted according to the protrusions and depressions on the surface of the tree, ensuring stability and adaptability during the crawling process. Specifically, when the diameter of the tree or the protrusions and depressions cause the installation column 4 to move, it will act on the push plate 302 under the action of the hydraulic pressure.

When the value of the pressure sensor 306 changes, the controller can control the electric telescopic rod 301 to extend or retract to ensure the stability of the value of the pressure sensor 306.
[0044] By using the connecting folded pipe 903, the hydraulic strength in the auxiliary box 9 and the adjacent L-shaped end box 3 can be synchronized, and the stability of the robot during operation can be further improved.
[0045] As a further solution of the present invention, the flipping drive assembly includes a dual-axis drive motor 5 fixedly mounted on one side of the main board 2, and a worm 501 is fixedly connected to the output shaft of the dual-axis drive motor 5, and a pair of limiting arc plates 605 are also fixedly mounted at the position of the main board 2 near the dual-axis drive motor 5, and an inner tooth arc plate 604 is fixedly connected to one side of the two side plates 1, and the inner tooth arc plate 604 is slidingly connected to the limiting arc plate 605, and a pair of extension rods 602 are fixedly mounted at the position of the main board 2 near the limiting arc plate 605, and each pair of extension rods 602 is installed with a mounting rod 6 for rotation together, and each mounting rod 6 is fixedly installed with a worm wheel 601 and a transmission gear 603, the worm wheel 601 and the worm 501 are meshed with each other, and the lift angle between the worm 501 and the worm wheel 601 is smaller than the friction angle, and the transmission gear 603 is meshed with the inner tooth arc plate 604.

[0048] As a further solution of the present invention, the protective assembly includes two pairs of cantilever rods 101 fixedly installed on the outside of the side panel 1, and the top of each pair of cantilever rods 101 is fixedly connected with an arc-shaped outer rod 7, and a U-shaped frame 201 is fixedly installed on the top of the main board 2.
[0049] Furthermore, an extension rod 705 is fixedly connected to the end of one of the arc-shaped outer rods 7, and an insertion port 704 is provided on the other arc-shaped outer rod 7; this design enables the two arc-shaped outer rods 7 to be plugged and fixed to each other.
[0050] Furthermore, a connecting side rod 707 is fixedly installed at one end of the two arc-shaped outer rods 7 close to the U-shaped frame 201, and a corrugated membrane 202 is fixedly connected between the two connecting side rods 707 and the U-shaped frame 201.

[0052] Furthermore, different numbers of mounting tubes 701 are fixedly installed on the arc-shaped outer rod 7 and the U-shaped frame 201, and extension columns 702 are slidably installed in the mounting tubes 701.

[0054] Furthermore, the ends of the two side panels 1 are provided with staggered engaging slots 11; the engaging slots 11 enable the two side panels 1 to be plugged and fixed to each other, thereby improving the operating stability of the robot.
[0055] The specific working method is: when in use, the main board 2 of the robot is placed on one side of the trunk, the dual-axis driving motor 5 is controlled to start, the worm 501 is driven to rotate, and the installation rod 6 is driven to rotate through the transmission action of the worm wheel 601, and the inner gear arc plate 604 is driven to move along the limit arc plate 605 through the transmission action of the transmission gear 603, thereby realizing the flipping of the side plate 1; when the two side plates 1 move to both sides of the trunk, the limit abutting wheel 902 is set against the outer peripheral wall of the trunk, and the driving wheel 401 is set to make the robot stably embrace the trunk;
[0056] By using the electric telescopic rod 301, the pressure sensor 306 and the push plate 302, the trees with different diameters can be effectively fitted and gripped. At the same time, the pressure can be automatically adjusted according to the protrusions and depressions on the surface of the tree, ensuring the stability and adaptability during the crawling process. Specifically, when the diameter of the tree or the protrusions and depressions cause the installation column 4 to move, it will act on the push plate 302 under the action of the hydraulic pressure. At the same time, in conjunction with the connecting square tube 305, when the hydraulic pressure inside the L-shaped end box 3 increases, the electric telescopic rod 301 will return under the action of the subsequent controller. The hydraulic pressure in the L-shaped end box 3 is pumped out, and the hydraulic pressure in the L-shaped end box 3 is reduced to the pressure setting value of the pressure sensor 306; on the contrary, when the hydraulic pressure in the L-shaped end box 3 is reduced, the electric telescopic rod 301 will be extended under the action of the subsequent controller, and the hydraulic pressure in the L-shaped end box 3 is increased to the pressure setting value of the pressure sensor 306. In summary, the tree climbing robot automatically compensates for the abutment force between the driving wheel 401 and the tree trunk, and maintains the abutment force constant, so as to avoid unstable climbing or even slipping due to the abutment force between the driving wheel 401 and the tree trunk fluctuating.
[0057] The controller is set to receive the pressure value of the pressure sensor 306 and monitor the robot's embracing force on the tree trunk. When the value of the pressure sensor 306 changes, the controller can control the electric telescopic rod 301 to extend or retract to ensure that the value of the pressure sensor 306 is stable; the connecting folding pipe 903 is set to synchronize the hydraulic strength in the auxiliary box 9 and the adjacent L-shaped end box 3, and further improve the stability of the robot during operation;
[0058] Finally, when the two side panels 1 are flipped, the corrugated membrane 103 is adaptively retracted and expanded, and cooperates with the protective cover 102 to provide good protection for the outside of the robot; the extension column 702 and the mounting tube 701 cooperate with each other, and cooperate with the rolling ball 703 to provide adaptive retractable protection. At the same time, the rolling ball 703 can also improve the robot's adhesion and embracing effect on the tree trunk and reduce the occurrence of slipping.
