Description

A kind of movable power supply slide device

Technical field

The present invention relates to a kind of slide device, the movable power supply slide device of especially a kind of straddle truck.

Background technology

The slide wire power supply mode of straddle truck adopts fixed naked steel trolley mostly at present, straddle truck generally all is to work in weather awning, leave weather awning work if require straddle truck, just must prolong fixedly trolley length, need on the column of roof truss, increase the unsettled fixedly fine strain of millet of single head like this, but can influence column intensity like that, especially can produce unsafe factor, produce not attractive in appearance to whole factory building simultaneously anti-platform.Therefore just need a kind of movable power supply slide device, the scope of activities of straddle truck is increased.Gantry crane sliding contact line mobile power supply device as the patent No. 200910301665.5, be to adopt the suspension type trolley, form by suspension, connector, contact slide block three parts, the contact slide block is made up of wiping roller, glass fibre reinforced plastic insulating plate, trolley is set up in the groove of roller, and the upper outside of glass fibre reinforced plastic insulating plate connects upward band iron by bolt, and a cover wiping electric power system is made up of three contact slide blocks, the contact slide block is connected with suspension by connector, and suspension is connected with the support of straddle truck.Can provide continuous power supply for straddle truck moves by this device, and cost is lower.Its power is less, is fit to the little straddle truck of tonnage and uses, if the above straddle truck of 100T just needs good several units, it is unsafe hanging the number table apparatus on straddle truck fuselage support.

Summary of the invention

Technical problem to be solved by this invention is the present situation at prior art, and a kind of reliable, simple and reasonable movable power supply slide device is provided.

The present invention solves the problems of the technologies described above and the technical scheme that adopts is: a kind of movable power supply slide device, be installed on the support of straddle truck, comprise trolley, wiping piece, it is characterized in that comprising a rail chair, the upper and lower both sides of rail chair respectively are mounted with a track, and the sidepiece of rail chair has the through hole that main shaft is placed; Be provided with the roller that matches with track in the middle of the upper and lower track, the middle part of roller has the cavity that main shaft is passed through; Main shaft is arranged in the roller by bearing, in be lined with the jewel circle and main shaft passes roller cavity, rail chair through hole successively.

Described Bearing Installation is provided with two and employing self-aligning ball bearing, the outer ring raceway of self-aligning ball bearing is sphere shape, has the automatic aligning performance, can compensate the error that nonconcentricity and shaft deflection cause, the bearing stifle is fixed on the roller by fixture, makes the logical jut of bearing stifle compress bearing.

The front end of described main shaft is set in and is positioned at the rail chair outside, vertically the fixing hole at trunnion shaft middle part is set.

The upper and lower edge of described rail chair respectively has a butter mouth screw near the track place.

As improvement, described trunnion shaft is fitted on the rail chair by bearing.

As improvement, the bearing of described trunnion shaft adopts the deep groove ball bearing with two-sided dust cap, be distributed in the two ends up and down of trunnion shaft symmetrically,, play the effect of balance and stability with trunnion shaft and deep groove ball bearing because device also will bear certain axial force in the bearing radial force when sliding.

As improvement, the cambered surface that the active face of described roller is set to spill matches with the circular face of track.

In the whole device, main shaft is crucial, obtains all better comprehensive mechanical property of intensity, plasticity, toughness with modified the making of 45#, and track adopts seamless steel pipe, and rail chair adopts channel-section steel, can determine the length of track according to the scope that moves.

Operation principle of the present invention is: when straddle truck reached the trolley terminal point, just to run into terminal point spacing for the Fang Songtou of main shaft, and this device plays a role, and trolley is contacted with wiping piece on the main shaft.

Compared with prior art, the invention has the advantages that: utilize this device can make straddle truck shift out weather awning east, west two edge works, shorten the segmentation time of shipment greatly, and guaranteed the heap(ed) capacity that the weather awning internal field makes, this apparatus structure advantages of simple, cost is low and safe and reliable to operation.

Embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

A kind of movable power supply slide device is installed on the support of straddle truck, comprises a rail chair 9, and the upper and lower both sides of rail chair 9 respectively are mounted with a track 1, and the sidepiece of rail chair 9 has the through hole that main shaft 3 is placed; Be provided with the roller 2 that matches with track 1 in the middle of the upper and lower track 1, the middle part of roller 2 has the cavity that main shaft 3 is passed through; Main shaft 3 is arranged in the roller 2 by bearing 5, in be lined with jewel circle 4, and main shaft 3 passes roller cavity, rail chair through hole successively, and roller 3 can be rotated around main shaft 3 between last lower railway.

Bearing 5 is installed and is provided with two and employing self-aligning ball bearing, the outer ring raceway of self-aligning ball bearing is sphere shape, has the automatic aligning performance, can compensate the error that nonconcentricity and shaft deflection cause, bearing stifle 6 passes through the fixture screw on roller 2, make the jut of bearing stifle 6 compress bearing 5, the front end of main shaft 3 is set in the fixing hole that is positioned at the rail chair outside, vertically disposed trunnion shaft 8 middle parts.

The upper and lower edge of rail chair 9 respectively has a butter mouth screw 10 near track 1 place, adds butter on the track to increase roller sliding in orbit in the past; The cambered surface that the active face of roller 2 is set to spill matches with the circular face of track 1.

Trunnion shaft 8 is fitted on rail chair 9 lateral surfaces by bearing 7, the deep groove ball bearing that the bearing 7 of trunnion shaft 8 adopts with two-sided dust cap, be distributed in the two ends up and down of trunnion shaft 8 symmetrically, because device also will bear certain axial force in the bearing radial force when sliding, play the effect of balance and stability with trunnion shaft and deep groove ball bearing.

In the whole device, main shaft is crucial, obtain all better comprehensive mechanical property of intensity, plasticity, toughness with modified the making of 45#, the scope that can move is as requested determined the length of track, the 100T straddle truck we require straddle truck to leave each 6 meters on weather awning Wai Dong, western both sides, so track adopts Φ 27 * 3 seamless steel pipes, rail chair adopts two 12 meters long tracks of 18# channel-section steel (180 * 70) to be installed on the channel-section steel.

The fixedly trolley of installing in the weather awning, when straddle truck reached the trolley terminal point, just to run into terminal point spacing for the Fang Songtou of main shaft 3, and this device plays a role, and trolley is contacted with wiping piece on the main shaft, and this and traditional structure are similar.

It is installed in the eminence of 19.5 meters of 100T straddle trucks.Along with straddle truck outwards moves, the other end bearing of main shaft and roller be rolling in orbit, and the distance of rolling is spacing to be slightly less than 6 meters of the distances of straddle truck lower limit.
