Description
Technical field
The present invention relates to a kind of automatic electricity taking device, especially a kind of bell guide of the trolley of electricity getting device.
Background technology
With economic trade communication increasingly closely, port traffic industry also flourishes, existing harbour
Container pier storage yard loads and unloads general lifting machine, mainly there is two kinds, and one kind is rail-mounted gantry crane, and another kind is wheel
Tire hanging gantry.
Goods yard operation power of the rail-mounted gantry crane on harbour is the electricity for using power network, but because whole machine is along fixed
Track travel, and be that track is limited by service cable length, can not especially make longitudinal transition operation.The power supply mode is current
On the automatic assembly line and fractional orbital formula plant equipment that can be only applied to have fixed running track in workshop.
The whole machine of tire type gantry crane is walked, and is the pneumatic tire that use can be turned to, therefore can reach whole with transition
Any position operation of individual goods yard, can be freely to carry out transition.On harbour automatic improving direction, lower frame trolley
Automatic power taking is one of now common mode.Contact of the horn mouth in automatic power taking to current-collector with trolley carries out level
With the guiding in vertical direction, play the role of irreplaceable.
Existing Full-automatic tire hangs the bell guide of trolley in automatic transition device.Such as Application No.
A kind of tyre type gantry crane intelligent electrical collector system disclosed in 200810163015.4 Chinese patent, including track, rail
Road is provided with safety sliding contact line, and safety sliding contact line is provided with slip and imports horn mouth, and the brushing piece of current-collector imports horn mouth and leads by slip
Enter safety sliding contact line；And for example disclosed in the Chinese patent of Application No. 201110198126.0 it is a kind of for gantry from
Dynamic electricity-fetching mechanism, including plug frame and receptacle boxes, receptacle boxes include trolley, trolley horn mouth, and gantry crane is with slotting
, to the side shifting of trolley horn mouth one, the taking electrode of current-collector is smooth under the bell-mouthed guiding of trolley on plug frame for head frame
Slip into trolley.
These above-mentioned horn mouths are all fixed, and because trolley distance is more long, difference variation is drawn between causing the summer in winter
Expanding with heat and contract with cold for rising is serious, and fixed bell guide can distort trolley or produce gap, influence current-collector and trolley
Contact, increased fault rate.
The content of the invention
The technical problems to be solved by the invention are directed to the problem that above-mentioned prior art is present, there is provided one kind improves power supply

The sliding support 92 of support 91 and second be then it is horizontally disposed, it is vertical with each self-corresponding first chute 21, the second chute 31 respectively.
When 5 thermal expansion of trolley, trolley 5 promotes bell guide main body to be moved to the direction away from trolley 5, now
The position of the first sliding support 91 and the second sliding support 92 is as shown in Figure 5 and Figure 6；When 5 shrinkage of trolley, trolley 5 draws
Action-oriented horn mouth main body is moved to the direction of trolley 5, now the position of the first sliding support 91 and the second sliding support 92
As shown in Figure 7 and Figure 8.Thus, bell guide of the invention can float on the bearing of trend of trolley, solve original solid
The distortion of trolley when expanding with heat and contract with cold or the defect in generation gap that fixed bell guide is present, it is ensured that lower frame trolley power taking
The reliability service of device.Additionally, bell guide is for outdoor type is ageing-resistant, fire-retardant, antiultraviolet, excellent insulating property is resistant to
Pressure 3500V does not puncture.
Embodiment two
Referring to Fig. 9~Figure 14, in the present embodiment, the difference with above-described embodiment one is to be substituted by interfacing part 4 '
Slip fixed plate 4, realizes the connection of trolley 5.
The front end of trolley 5 is connected to interfacing part 4 ', and interfacing part 4 ' is connected with wallboard 7.Specifically, interfacing part 4 ' is in
Hollow tubular, such as square tube or pipe, are provided with lug 41 ' on the top of interfacing part 4 ', the second mounting hole is offered on lug 41 '
411’.In the present embodiment, it is four interfacing parts 4 ', compartment of terrain is arranged in juxtaposition between two wallboards 7, each interfacing part 4 ' is even
Corresponding trolley 5 is connected to, is spaced apart by spacer 42 ' between two adjacent interfacing parts 4 ' and positioned.Second fastener, such as
Screw from the wallboard 7 of side penetrate after, the second mounting hole 411 ' sequentially passed through on interfacing part 4 ', again from the wallboard 7 of opposite side
Nut locking is used after passing, thus can be fixed by interfacing part 4 '.
The bottom of interfacing part 4 ' has slot 43 ' that is concave up and being formed, and slot 43 ' is on the length direction of interfacing part 4 '
Extend, and through the forward and backward two ends of interfacing part 4 ', so that can be connected with interfacing part 4 ' outside the bottom of interfacing part 4 '.It is right
The front end or rear end of fitting 4 ', the first mounting hole 431 ' is offered positioned at the top of slot 43 ', the front end of slot 43 ' is less than rear end,
After in the insertion interfacing part 4 ' of trolley 5, can be by the first fastener, such as bolt can be inserted into right from the first mounting hole 431 '
In fitting 4 '.
Trolley 5 is inserted into interfacing part 4 ' from the rear end of interfacing part 4 ', and fixed by bolt and interfacing part 4 ', and right
The front end of fitting 4 ' is 12 corresponding with the second end for importing plate 1, while fixed with wallboard 7 again, therefore complete the installation of trolley 5.
When power taking is needed, the carbon brush of current-collecting cart enters fashionable, in the horizontal direction can be by middle importing location-plate 61 and side
Import the gathering sill formed between location-plate 62 to be oriented to, then into the slot 43 ' of interfacing part 4 ', so that and interfacing part
The contact conducting of trolley 5 in 4 '.
