The working process of the invention is as follows: use climbing robot to stride across right angle wall as an example, vacuum pump 2 takes out the interior air of vacuum cavity subassembly 1 through trachea 3 during initial state for two sets of vacuum adsorption telecontrol equipment all adsorb in vertical wall. At this time, the spring 19 in the spring assembly is in a compressed state, and pushes the chassis 6 to drive the whole moving assembly to press on the vertical wall surface. The motor III 14 is started to drive the large belt wheel 7, the synchronous belt 13 is operated through the small belt wheel 9 and the supporting wheel 16, and then the two groups of vacuum adsorption moving devices move on the vertical wall surface simultaneously. When detecting the right angle wall and needing to stride across, one side vacuum pump 2 stops the power supply, this side vacuum adsorption telecontrol equipment and wall separation, energy storage arm module 4 operates and delivers this side vacuum adsorption telecontrol equipment to right angle wall target location, and stop with the gesture that the right angle wall is about to the laminating, this side vacuum pump resumes the power supply, adsorb this side vacuum adsorption telecontrol equipment in right angle wall, opposite side vacuum pump 2 stops the power supply, deliver to right angle wall target location with opposite side vacuum adsorption telecontrol equipment by energy storage arm module 4, so far accomplish the robot and stride across right angle wall.
Regarding to the situation that the climbing robot is adsorbed on a wall surface to move and has the obstacle crossing function, the mechanical arm must have weight limitation (for example, the total weight of a driving device at the central joint of some mechanical arms cannot exceed 1kg, the torque cannot be lower than 20Nm and meet a certain rotating speed requirement, or other situations with weight limitation) under the condition that the power requirement is met, therefore, some traditional climbing robots with the obstacle crossing function directly adopt motor driving, and the mode is easy to cause that the obstacle crossing cannot be effectively crossed due to insufficient torque, or the torque is sufficient, and the climbing robot cannot effectively adsorb the climbing wall due to overlarge weight. And the energy storage arm of this application, through energy storage module's setting, the extreme moment that is used for compensating extreme position is stored to the gravitational potential energy when climbing robot operation, and then reduces driving motor's power demand under satisfying the operating condition.
How to construct the energy storage module through reasonable synthesis and connection is very important for climbing robots to cross obstacles. According to the wall climbing robot, the spring box cover 36, the spring 37 and the spring box 38 are arranged on the transmission shaft 42 with the energy storage structure from one end to the other end, and then the damping box cover 39, the damping brush 40 and the damping box 41 are arranged, so that the stability is better, the improvement of the stability not only can reduce the energy loss of stored elastic potential energy, but also can ensure that the wall climbing robot can effectively climb the wall; the vibration reduction brush 40 consisting of a piston ring 40-1, a rubber pad I40-2, a rubber pad II 40-3 and a sealing pad 40-4 is further matched, so that the vibration reduction brush stably runs, effectively eliminates vibration, reduces motion impact, reasonably releases stored energy and meets the control requirement; meanwhile, damping paint can be smeared on the sealing gasket.
The position of the climbing robot for generating the maximum gravitational potential energy is that the rotating arm II 25 and the rotating arm III 26 are in the same straight line, and at the moment, the rotating arm naturally falls under the action of gravity and stores energy through the energy storage module. The speed ratio of the planetary speed increaser 33 of the invention is therefore set to 1: 10, the spring 37 is made of 55SiMnVB with the width of 3cm, the damping coefficient of the vibration reduction brush is 0.65, and the balance of the resistance generated by the vacuum adsorption movement device and the gravity of the mechanical arm, the damping generated by the vibration reduction brush and the elastic force of the spring can be further ensured through the arrangement, so that the middle joint of the mechanical arm can move at a constant speed.
The working principle of the energy storage module is as follows: taking the mechanical arm in an initial state as an example of a straight line vertically downward, a motor II 30 fixed to a rotating arm II 25 provides a driving force to enable the rotating arm III 26 to rotate relative to the rotating arm II 25, and meanwhile, the power is transmitted to a planetary speed increaser 33 through a short shaft III 44, and the speed increaser has a speed increaser ratio of 1: 10, when the motor II 30 extends out of 1/2 circles, the planetary speed increaser 33 extends out of 5 circles. The extension shaft of the planetary speed increaser 33 transmits power to a transmission shaft 42 through a coupler 34, the transmission shaft 42 drives a spring 37 to rotate and store elastic potential energy, and meanwhile, a damping brush 40 rotates in a damping box 41 to eliminate vibration. When the mechanical arm moves in a return stroke, the motor II 30 drives the rotating arm III 26 to move in the opposite direction, the transmission is carried out through the planetary speed increaser 33, the spring 37 releases the stored elastic potential energy, and the vibration is eliminated through the vibration reduction brush 40. At the moment, the energy storage module is used for assisting power, the torque required by the motor II 30 is reduced, and the other two joints of the mechanical arm are used for driving the mechanical arm to reach the target position.
While the present invention has been described in detail with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
