Description
Technical field
The utility model relates to a kind of magnetic adsorption wall climbing robot or mechanical car uses road wheel, specifically is a kind of improved combination magnet-wheel.
Background technology
Current, at hull, surfaces such as metal can attach the machine of principle of work with magnetic; The walking of its magnetic adsorption wall climbing robot or magnet-wheel machinery engineering truck, turning gear mechanism, at present common two types of crawler type and the magnetic wheel types that mainly contain; Its advantage of crawler type walking mechanism: adsorption affinity is strong, and carrying force is bigger.Shortcoming: be complex structure, make and require height.Turn to difficulty and required drive big when on the magnetic conduction wall, moving, walking resistance is big, and speed is unstable uneven, the posttension of toppling easily when crossing obstacle, and difficulty when carrying out comprehensive operation, efficient is low.
With circular magnet steel is the rolling train that wheel is formed, and advantage is to turn to flexibly, and required drive is little, and shortcoming is that adsorption affinity is poor, and loading weight is little, and the magnetic degree of utilization is low.
Application number is the magnetic conduction wheel unit that 200510040579.5 disclosed a kind of common magnet-wheel machinery engineering truck machine is used, and its defective is obvious from:
1. on magnetic conduction wheel border, garden, carry out annular knurl,, very easily polish, polish the back wheel face and reduce, be easy to generate slippage, so the frequent disassembling, assembling and replacing magnetic conduction wheel of train group, very inconvenience and strengthened the cost input with wall friction power owing to use.The external drain electrode easy-to-rust of this element magnet steel, and magnet steel is easy to damage when running into the wall salient point,
2. because magnet steel and magnetic conduction are taken turns no located in connection, magnet steel can't keep coaxial with the magnetic conduction wheel, so magnet steel is frequent and wall friction causes damage.
3. and these wheels only adopt the tight latch mechanism of nut, do not fixedly connected,, cause and normally to walk so wheel shaft can not be synchronous with the commentaries on classics of the normal generation of magnetic conduction wheel relative mistake during walking because of having between wheel shaft and magnetic conduction wheel.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of improved combination magnet-wheel.
The utility model is realized through following technical scheme: a kind of improved combination magnet-wheel; It comprises the limit magnetic conduction wheel that two permeability magnetic materials of device on wheel shaft are made; The middle magnetic conduction wheel that escapement several permeability magnetic materials in the middle of two limit magnetic conduction wheels are own are made is embedded with an annular arrangement magnet steel between per two adjacent magnetic conduction wheels; The whole two ends of the fabricate block of magnetic conduction wheel and magnet steel are fastened on the wheel shaft through catch gear; The excircle of described limit magnetic conduction wheel has the crossette that inwardly stretches out; The excircle of magnetic conduction wheel has crossette in the middle of each; Magnet steel is clipped in the groove that forms under the crossette of two adjacent magnetic conduction wheels; On the outer circumference surface of limit magnetic conduction wheel and middle magnetic conduction wheel, arc spraying metal bisque is arranged, on the outer circumference surface of magnet steel, be set with not magnetic conductive metal circle; On limit magnetic conduction wheel, middle magnetic conduction wheel and wheel shaft, have keyway, limit magnetic conduction wheel, middle magnetic conduction wheel and magnet steel are locked with the stainless steel key, stop washer and the circular nut that cooperate with keyway and wheel shaft and are in the same place.
Owing to adopted technique scheme, annular arrangement not the magnetic conductive metal snare on the magnet steel cylindrical, make magnet steel be in full closeding state, the magnet steel actv. has obtained protection, has improved the service life of magnet steel greatly.Limit magnetic conduction wheel has arc spraying metal bisque with middle middle magnetic conduction wheel on its periphery; Make the wheel surface hardness reach HRC62; And having increased roughness, wheel face is compared with the annular knurl wheel face with the friction force of wall and has been improved 50%, has not only prolonged the service life of magnetic conduction wheel but also increased load carrying ability; Be employed on wheel shaft and the magnetic conduction wheel and have keyway; Through the connection that fixes of stainless steel key; Wheel shaft one end is locked the limit magnetic conduction wheel that assembles, middle magnetic conduction wheel and magnet steel with stop washer and circular nut, when having avoided wheels to rotate the magnetic conduction wheel with magnet steel loosening and when rotating wheel shaft produce poor commentaries on classics with limit magnetic conduction wheel, middle magnetic conduction wheel.
The beneficial effect of the utility model is: preferably resolve getting rusty and frangible defective of magnet steel; Limit magnetic conduction wheel and the magnetic conduction wheel wheel face of centre and the friction force of wall have been strengthened; And the service life of having improved limit magnetic conduction wheel, middle magnetic conduction wheel and magnet steel greatly; Increase load carrying ability more than 30%, solved magnetic conduction wheel sheet and wheel shaft simultaneously and produced difference commentaries on classics problem, make the utility model get into practical application area fully.
