Abstract
The utility model discloses a contactless magnetically stable mobile device which comprises an outer clamping plate, an inner clamping plate and front and rear wheels arranged between the outer and inner clamping plates, wherein a permanent magnetic fixator is further arranged between the outer and inner clamping plates, and the bottom face of the permanent magnetic fixator is located within a connecting line between the front and rear wheels and the wheel diameter face contacted with a track. When the device moves, as the permanent magnetic fixator is not contacted with a rail, suction of the permanent magnetic fixator to the rail can be overcome through a manual or a motor device to push box steps to travel along the rail so as to poll and maintain an electric power transmission overhead line system. The box steps are maintained in a stable state on the rail by means of suction between the contactless magnetically stable mobile device and the rail. When personnel step over the outer side of a work basket and the centre-of-gravity shifts or personnel maintain a bend, the box steps do not turn on the side even if the box steps are in an inclined state. In maintenance operation, the box steps can be moved to travel anytime. The contactless magnetically stable mobile device has the advantages of convenience in use and safety and reliability.
Description
Technical field
The utility model belongs to mobile device, is specifically related to the firm mobile device of a kind of contactless magnetic.
Background technology
Railway locomotive electric power carries contact net when Maintenance and Repair, conventionally to use the locomotive ladder of orbital motion.Existing locomotive ladder does not have fastening devices mostly, during use, because ladder can not be fixed, easily occurs deviation of gravity center, turn on one's side, cause the generation of security incident, cause casualties and facility damage, while overhauling on ramp, car ladder slips simultaneously, and unfavorable work, also may cause security incident.Also have the car ladder of fixing device for installing, during still this car ladder operation, every place must operate fastening devices car ladder is fixed on rail, time-consuming, effort that workman is generally reflected.
Utility model content
The purpose of this utility model be to provide a kind of easy to use, can suitably be fixed on the firm mobile device of contactless magnetic on rail.
The technical scheme that realizes the employing of the utility model object is as follows:
The firm mobile device of contactless magnetic, comprise external splint, inner splint, be located at external splint, the front and back wheel between inner splint, between external splint, inner splint, be also provided with permanent magnetic fixer, within the line between the wheel diametric plane that the bottom surface of described permanent magnetic fixer contacts at described front and back wheel and track.
Described permanent magnetic fixer is fixed between described external splint, inner splint by magnetic insulation parts.
The distance of the line between the bottom surface of described permanent magnetic fixer and described front and back wheel wheel diametric plane is 0.2-15mm.
The utility model has the advantages that, can be used as the running gear of locomotive ladder (or miscellaneous equipment), within line between the wheel face contacting at described front and back wheel and track due to the bottom surface of described permanent magnetic fixer, can guarantee that permanent magnetic fixer avoids dead on rail with rail is contactless all the time, because permanent magnetic fixer and rail distance are approaching, can guarantee again to there is larger suction between itself and rail simultaneously, therefore, both can locomotive ladder when contact net Maintenance and Repair, can in certain field of load, car ladder be suitably fixed on rail again, avoid car ladder during normal use because gravity center shift is turned on one's side, guarantee safety work.The utility model in use only needs once operation separately, very easy to use, safe and reliable.
Below in conjunction with accompanying drawing, further illustrate the technical solution of the utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the AA place view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, the firm mobile device of contactless magnetic that the utility model provides, comprise external splint 1, inner splint 1 ', be located at external splint 1, inner splint 1 ' between front and back wheel 6, 6 ', at external splint 1, inner splint 1 ' between be also provided with permanent magnetic fixer 2, permanent magnetic fixer 2 is fixed on external splint 1 by magnetic insulation parts 3 use screws 4, inner splint 1 ' between, the bottom surface 201 of described permanent magnetic fixer 2 is positioned at described front and back wheel 6, 6 ' and the wheel diametric plane that contacts of track a between line b within, bottom surface 201 and the described front and back wheel 6 of permanent magnetic fixer 2, the distance L of line b between 6 ' wheel diametric plane is 0.2-15mm.
Described permanent magnetic fixer 2 adopts commercially available product.
The utility model is as the running gear of locomotive ladder, running gear comprises four firm mobile devices of contactless magnetic, every two firm mobile devices of contactless magnetic are connected on a fixed axis 9, locomotive ladder comprises splayed ladder part 7 and the operation basket part being positioned at above splayed ladder part 7, and four pin of splayed ladder part 7 are separately fixed on the fixed axis 9 of front and back.During operation, because permanent magnetic fixer 2 is contactless with rail a, can overcome permanent magnetic fixer 2 by manpower or electric machine the suction of rail a is promoted to car ladder along rail a walking, to electric power, carry contact net to patrol and examine maintenance.Car ladder relies on contactless permanent magnetic fixer 2 and rail a suction to be each other fixed on that rail a is upper keeps stable state, although during centre-of gravity shift or during bend maintenance, car ladder is in heeling condition outside personnel's spanning operation basket, car ladder all can not be turned on one's side.In operation maintenance, the walking of locomotive ladder, has advantages of esy to use, safe and reliable at any time.
Claims (3)
