Detailed description of the invention
Core of the present invention is to provide a kind of pantograph erecting device of guideway vehicle, and this device has higher structural strength, can bear the vibration of generation in vehicle high-speed operation, impact and aerodynamic loading, meet the demand that vehicle safety runs.Another core of the present invention is to provide a kind of guideway vehicle comprising above-mentioned pantograph erecting device.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Here it should be noted that, the nouns of locality such as the upper and lower and bottom related to herein be all with parts shown in Fig. 1 be arranged in figure or parts mutual alignment close be benchmark definition; Should be appreciated that the use of the described noun of locality is just in order to state the clear of technical scheme and scheme, should not limit the protection domain of the application's request.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of detailed description of the invention of pantograph erecting device provided by the present invention.
In this embodiment, pantograph erecting device 10 comprises mount pad 11, slide block 12 and fastener 13.
Please composition graphs 3-4, Fig. 3 are the structural representation of mount pad in Fig. 1 in the lump; Fig. 4 is that the A-A of Fig. 3 is to cutaway view.
Mount pad 11 is fixedly arranged on car body 30, is provided with chute 11a bottom it, and has the chute hole 11b through with chute 11a, and this chute hole 11b matches with the mounting hole of pantograph 20.
It is pointed out that chute hole 11b refers to the through hole with opening herein, as shown in Figure 3.
Please composition graphs 5-6, Fig. 5 are the structural representation of slide block in Fig. 1 in the lump; Fig. 6 is that the B-B of Fig. 5 is to cutaway view.
Slide block 12 is adaptive with the chute 11a of mount pad 11, and has the slider throughbores 12a coordinated with chute hole 11b.
Fastener 13 runs through the slider throughbores 12a of slide block 12, the chute hole 11b of mount pad 11 successively, and the mounting hole of pantograph 20, pantograph 20 is fixed on mount pad 11, thus is fixed on car body 30.
During assembling, can first by pre-to fastener 13 and slide block 12 group, due to the hatch frame of chute hole 11b, the fastener 13 of pre-group and slide block 12 can slip into the predeterminated position of chute 11a by chute hole 11b, obviously, this predeterminated position refers to the position that slider throughbores 12a can coordinate with the mounting hole of pantograph 20; The fastener 13 of pre-group and slide block 12 after the position of chute 11a is determined, then assemble pantograph 20, the mounting hole of pantograph 20 is coordinated with fastener 13, completes the assembling of pantograph 20.Visible, due to the chute 11a of mount pad 11 and the vibrational power flow of chute hole 11b, make the space compression between mount pad 11 and car body 20 to minimum, reduce the whole height of pantograph erecting device 10, thus, in the process that track train is run at high speed, this device can bear larger shock and vibration and aerodynamic loading.
In addition, comparatively large with the area of contact of mount pad 11 by slide block 12, effectively can disperse the stress that mount pad 11 bears, improve the fatigue life of mount pad 11; And coordinating of slide block 12 and chute 11a can spline and location, each mounting hole dislocation when effectively preventing assembling, reduces assembly difficulty.
In concrete scheme, chute 11a is the groove along mount pad 11 horizontal expansion.
Here, the Width of mount pad 11 is laterally referred to.
Chute hole 11b can be located at the end of chute 11a, and that is, a chute 11a and two chute hole 11b is through.
Usually, pantograph 20 has four mounting holes, correspondingly, can arrange two chute 11a on mount pad 11.
In order to make the stress equalization of mount pad 11, avoid stress raisers, two chute 11a can be arranged symmetrically with along the longitudinal direction of mount pad 11.Obviously, the length direction of mount pad 11 is longitudinally referred to here.
Certainly, chute 11a also can be set to the structure of non-groove, as long as can match with chute hole 11b, slide block 12, so, a chute 11a coordinates with a chute hole 11b.
In contrast, the chute 11a of groove structure is convenient to batch machining, can the form of preferred groove in reality.
In addition, this embodiment schematically show only the structure of four chute hole 11b, if the mounting hole number of pantograph 20 is other numbers in reality, correspondingly can arrange the number of chute hole 11b.
In concrete scheme, mount pad 11 is fixed by the mode of welding with car body 30, not only easy but also reliable.
Certainly, also other fixed forms can be selected in reality.
More specifically, the middle part of mount pad 11 can arrange through hole 11c.
Through hole 11c arranges the weight that can alleviate mount pad 11 on the one hand, also can increase mount pad 11 and the weld seam of car body 30 on the other hand, make mount pad 11 more firm with fixing of car body 30.
Through hole 11c is preferably set to the form of slotted hole, certainly, actually also can be set to other shapes when arranging, as circular or oval etc.
In concrete scheme, the nut 132 that fastener 13 is bolt 131 and coordinates with bolt 131.
More specifically, bolt 131 can select outer-hexagonal bolt, and its tightening force is large, can fix pantograph 20 better.Certainly, actual when arranging, also can select other forms of bolt, be not limited thereto.
On this basis, slider throughbores 12a can be made up of the first hole portion and the second hole portion being positioned at this upper end, portion, the first hole; Wherein, the head of the first hole portion and bolt 131 is adaptive, and the second hole portion coordinates with the screw rod of bolt 131, so, can carry out spacing to fastener 13, and after avoiding assembling, fastener 13 loosens the normal work affecting pantograph 20.
The process adopting this pantograph erecting device 10 to install pantograph 20 is as follows:
First bolt 131 is inserted the slider throughbores 12a of slide block 12;
Again the bolt 131 assembled and slide block 12 are slipped into the chute 11a of mount pad 11; Obviously, when slipping into, the head of bolt 131 is positioned at lower end, and namely bolt 131 is in inverted state, and the screw rod of bolt 131 slips into from the opening of chute hole 11b; Slide block 12 can be understood with reference to figure 2 with coordinating of mount pad 11;
Finally assemble pantograph 20, the mounting hole of pantograph 20 is aimed at the screw rod of bolt 131, and be inserted in screw rod, pantograph 20 is supported by mount pad 11, then nut 132 is screwed in screw rod, pantograph 20 can be fixed.
When specifically arranging, between the attachment face of nut 132 and pantograph 20, bullet pad and plain cushion can be set, loosen to prevent nut 132.
Except above-mentioned pantograph erecting device 10, the invention also discloses a kind of guideway vehicle, comprise car body 30 and the pantograph erecting device 10 being arranged at described car body top, described pantograph erecting device 10 is pantograph erecting device described above.Other structures of guideway vehicle can refer to prior art, and it is no longer repeated herein.
Because above-mentioned pantograph erecting device 10 has above-mentioned technique effect, so the guideway vehicle comprising this pantograph erecting device 10 also has corresponding technique effect, no longer repeat here to discuss.
Above guideway vehicle provided by the present invention and pantograph erecting device thereof are all described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
