Detailed description of the invention
With embodiment, the present invention is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention includes that frame 10, frame 10 are rectangle frame structure, at four angles of frame 10 It is respectively provided with a track assembly 20, for realizing present invention absorption in vertical walls and walking.In frame 10 Top mechanical arm 40 is installed, for implementing the cleaning of wall, eliminating rust, spray paint and the action such as detection.
As in figure 2 it is shown, be provided with four steer motor 11 bottom frame 10, the outfan of each steer motor 11 All being fastenedly connected with a telescoping cylinder 12, the outfan of telescoping cylinder 12 and a track assembly 20 are fastenedly connected.
As shown in Figure 3, Figure 4, track assembly 20 includes chain rail 21, rubber belt track 22, magnetic absorbing unit 23 and hangs Hanging bracket 24.Wherein, magnetic absorbing unit 23 is multiple, and interval is fastenedly connected in the outside of chain rail 21;Rubber belt track The inner side of 22 is fastenedly connected with each magnetic absorbing unit 23.Chain rail 21 is by the drivewheel 25 of distribution triangular in shape, driven pulley 26 and regulating wheel 27 jointly prop up, drivewheel 25 and driven pulley 26 are all connected with suspension holdfast 24 by power transmission shaft, It is connected by connecting rod 28 between drivewheel 25 with driven pulley 26, between driven pulley 26 and regulating wheel 27, passes through connecting rod 29 connect, and are connected by expansion link 30 between regulating wheel 27 with drivewheel 25, flexible permissible by expansion link 30 Realize the tensioning to chain rail 21 and relax.It is fastenedly connected with support platform 31 on suspension holdfast 24, supports platform 31 and stretch The outfan of contracting cylinder 12 is fastenedly connected.
As shown in Fig. 5~7, magnetic absorbing unit 23 include cylindrical permanent magnet 231, left yoke 232, right yoke 233, On every magnetic piece 234 and under every magnetic piece 235, wherein, cylindrical permanent magnet 231 be rotatably arranged in by left yoke 232, Right yoke 233, on every magnetic piece 234 and under in the hollow cylinder that magnetic piece 235 is encircled into, the fastening of one end of hollow cylinder is even Being connected to back shroud 236, the other end of hollow cylinder is provided with protecgulum 237, is provided with steering wheel 238, rudder in protecgulum 237 The outfan of machine 238 is connected with cylindrical permanent magnet 231 by shaft coupling 239.Steering wheel 238 has 0 ° and 90 ° Two angle states, when steering wheel 238 is in 0 ° of angle state, the N pole of cylindrical permanent magnet 231 and position, S pole In horizontal direction (as shown in Figure 8), the magnetic line of force is from N pole, by left yoke 232, wall 60 and right yoke Ferrum 233 reaches S pole, forms Guan Bi;Now, magnetic absorbing unit 23 is the state of magnetizing, and magnetic absorbing unit 23 is filling Wall can be produced suction under magnetic state.When steering wheel 238 is in 90 ° of angle states, cylindrical permanent magnet 231 Vertically (as shown in Figure 9), the magnetic line of force is from N pole, respectively by left yoke 232 He for N pole and S pole Right yoke 233 arrives S pole, forms two closed-loop paths;Now, magnetic absorbing unit 23 is erasing state, the magnetic line of force Loop gets around wall, and magnetic absorbing unit 23 does not produce suction to wall 60.
The control signal that two angle states of steering wheel 238 are sent by panel 241 determines, panel 241 is arranged There is bluetooth communication, make the panel 241 can be by Bluetooth signal with the controller being arranged in frame 10 (in figure Not shown) transmission signal, controller can need long-range control each magnetic absorbing unit 23 in the state of magnetizing according to actual condition And switch between erasing state.
In above-described embodiment, on suspension holdfast 24, the position near drivewheel 25 and driven pulley 26 is respectively mounted one NFC sensor, is embedded with NFC chip on the panel 241 of each steering wheel 238.Rotate at rubber belt track 22 During, when a certain magnetic absorbing unit 23 to drivewheel 25 near enough near time, NFC sensor passes through NFC core Sheet identifies this magnetic absorbing unit, and identification information is sent to controller, and controller receives after identification information to steering wheel The panel 241 of 238 assigns control instruction, makes steering wheel 238 switch to the state of magnetizing;When a certain magnetic absorbing unit 23 To driven pulley 25 in time obtaining enough near, NFC sensor identifies this magnetic absorbing unit by NFC chip, and will know Other information is sent to controller, and controller assigns control instruction to the panel 241 of steering wheel 238 after receiving identification information, Steering wheel 238 is made to switch to erasing state.Thus enable the invention to advance glibly.
In above-described embodiment, two power supply contacts 240 of both positive and negative polarity can be set on the protecgulum 237 of magnetic absorbing unit 23, Power supply contact 240 is connected with the in-line power circuit of steering wheel 238, is provided with power supply rail in frame 10 (in figure not Illustrate), the power supply contact 240 on each steering wheel 238 obtains power supply by power supply rail.
In above-described embodiment, mechanical arm 40 is sixdegree-of-freedom simulation, can install at the end of sixdegree-of-freedom simulation Different end effectors, thus complete to clean, eliminate rust, spray paint and the work such as detection.
In above-described embodiment, can install photographic head 50 in the front end of frame 10, photographic head 50 is used for capturing the present invention The working environment information in front also passes ground control terminal back by the way of being wirelessly transferred in real time.
It is characteristic of the invention that the ability arbitrarily turned to, specifically: when the present invention needs to turn to, frame 10 will be in It is raised up to unsettled (utilizing telescoping cylinder 12) after two track assemblies 20 demagnetization on diagonal, then passes through steer motor 11 drive two unsettled track assemblies 20 to turn to, and after having turned to, these two track assemblies 20 are magnetized and are stretched out Fit to wall.Afterwards, unsettled by being raised up to after two other track assembly 20 demagnetization, then pass through steer motor 11 drive two unsettled track assemblies 20 to turn to, and after having turned to, these two track assemblies 20 are magnetized and are stretched out Fit to wall.So far, the entirety completing equipment turns to, and continues to drive four track assemblies 20 to rotate, and equipment is i.e. Can carry out in the new direction.
The present invention only illustrates with above-described embodiment, the structure of each parts, arranges position and to connect be all to have Changed, on the basis of technical solution of the present invention, all improvement individual part carried out according to the principle of the invention and Equivalents, the most should not get rid of outside protection scope of the present invention.
