In the present embodiment, in magnetic adsorption wall climbing robot, the main task of adsorbing mechanism is to make the suction of robot steadily Water cooling wall surface is invested, so the design of adsorbing mechanism mainly consists of two parts, be respectively as follows: (1) electromagnet 31: electromagnet is mentioned For suction, guarantee that robot can be adsorbed on wall surface;(2) 1 structure of iron block designs: iron block is used to be bonded water cooling wall surface, shape It is very crucial.Robot tyre slip in order to prevent, electromagnet should be distributed in around tire, provide enough positive pressures for tire Power, so two wheels in robot respectively have an electromagnet up and down, entire robot is made of two identical robots, So sharing eight electromagnet.When robot is in obstacle detouring state, only there are four magnet to provide suction.In view of robot is whole Body structure is compact, and the electromagnet volume of selection should be smaller, so selection sucked type electromagnet.Water screen tube surface is special Different is arc-shaped, and electromagnetism iron surface is flat, so electromagnet can not be directly bonded with wall surface.In order to be preferably bonded wall surface An arc-shaped iron block is needed to carry out transition, the material of iron block is 45 steel.Iron block be designed as on one side it is arc-shaped, be used to and wall surface patch It closes;It is designed to plane on one side, is used to and electromagnet is bonded;There are four the threaded holes of M6 around flat one side, for fixing iron block.
In magnetic adsorption wall climbing robot, the main task of movement mechanism is to enable robot with certain speed stable It creeps, that is, the driving force generated can overcome the frictional force and the gravity of itself of iron block and wall surface, therefore the design of movement mechanism Mainly consist of two parts, be respectively as follows: (1) tire: tire size is related with the driving force of robot speed, offer;(2) wheel Driving motor: motor determines the driving force and speed of robot.In view of creep speed and load capacity, magnetic adsorption wall climbing machine Device person has selected in-wheel driving.Water screen tube surface is made of carbon steel, and in order to increase friction, tire selects rubber material.Tire It needs to be in close contact with water screen tube, iron block and wall surface are also required to contact, so needing to determine diameter of tyres according to iron block thickness. Tire mainly with arc-shaped water pipe highest point contact, measures the distance of iron block arc-shaped highest point and motor axis center, final to select Select agv trolley tire 3.The driving force of tire is provided by motor, it is contemplated that the small volume of robot and entire machine are artificial Direct current supply, therefore be connected directly with by the way of retarder one with tire using brshless DC motor, this mode reduces centre Transmission link, effectively save space.
In magnetic adsorption wall climbing robot, the main task of barrier getting over mechanism is the barrier for making robot cross water screen tube surface Hinder object.Water cooling wall surface is primarily present two class barriers, and the first kind is flow-disturbing crossbeam, mainly regular to be distributed in Vertical Square To, it is therefore desirable to the barrier getting over mechanism for designing vertical direction is named as vertical barrier getting over mechanism;Second class is by the circular water pipe of wall surface Caused barrier, the regular distribution of left and right directions, it is therefore desirable to which the barrier getting over mechanism for designing left and right directions is named as left and right and gets over Hinder mechanism.Vertical barrier getting over mechanism is made of link mechanism and brush holder type electric pushrod, and electric pushrod one end is hinged on walking unit On, the other end is hinged on connecting rod.The connection type of brush holder type electric pushrod and connecting rod is that a upper aluminium is first welded on connecting rod Alloy hinged block, brush holder type electric pushrod one end and aluminium alloy hinged block are bolted.When electric pushrod elongates or shortens, Connecting rod rotation is driven, the angle of parallelogram generates variation, and the height of robot also changes therewith.Left and right barrier getting over mechanism is by electricity Machine and rack-and-pinion composition are equipped with linear guide when moving in order to reduce friction and keep movement more stable in mechanism.
In magnetic adsorption wall climbing robot, the main task of bindiny mechanism is for connection to each mechanism of robot, master It to include chassis, top cover 4, barrier getting over mechanism platform 19.Chassis is mainly used to place motor, electromagnetism in magnetic adsorption wall climbing robot Iron and iron block, there are specific fixed frame on chassis, motor fixing frame is used to fix motor, and it is strong that both sides have rib to strengthen structure Degree;Electromagnet and iron block fixed frame are used to fixed electromagnet and iron block;Column has M6 threaded hole, is used to connect with top cover.Top It covers and is mainly used to place linear guide and rack-and-pinion in magnetic adsorption wall climbing robot, and the part on chassis is encased and is played Protective effect, the fixation for linear guide, by top cover punching it is solid with screw bolt and nut.Barrier getting over mechanism platform 19 is in magnetic It is mainly used to connect the sliding block of linear guide, electric machine support, the hinge of connecting rod in adsorption wall climbing robot and brush holder type is electronic pushes away The hinge of bar.
As shown in fig. 1, for tire by the motor axis connection of key 2 and wheel drive motors, 6,7 be a pair of bolts and spiral shell Mother, 8,9 be a pair of bolts and nut, and 10 be bolt, and 11,12 be a pair of bolts and nut, and connecting rod 14 is aluminum alloy connecting rod, and 18 are Bolt, 20,21 be a pair of bolts and nut.
As shown in Fig. 2, 27,29 be bolt, 30 be the pedestal 30 for installing DC brushless motor.
As shown in figure 3,32 be bolt.
The utility model is made up of two identical walking units link mechanism, is needed during vertical obstacle detouring Two walking units cooperate obstacle detouring, and obstacle detouring process is as follows:
(1) magnetic adsorption wall climbing robot drives agv trolley tire 3 to climb by the DC brushless motor 28 with retarder Then row stops creeping until encountering obstacle, II electromagnet 31 of walking unit power-off, elongation brush holder type electric pushrod 15 lifts Walking unit II.
