The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated.
Fig. 2 is the structural representation of block key device embodiment of the present invention, Fig. 3 is that the block key device among Fig. 2 is assemblied in the structural representation on the bogie side frame, and Fig. 4 is the perspective view of structure shown in Figure 3, shown in Fig. 2 ~ 4, the block key device of present embodiment comprises: block key body 10, bolt 20 and pin 30.Wherein, described block key body 10 comprises: be used for the backstop wheel to 300 the first connecting portion 12 and the second connecting portions 13 that break away from the stopper section 11 of bogie truck and be used for being connected with the side frame guide 210 of bogie side frame respectively, three parts form bending structure, described the first connecting portion 12 has the first through hole 121, and the position of the first through hole 121 is corresponding with the lead to the hole site on the side frame guide 210, in order to wear bolt 20, described the second connecting portion 13 and the first connecting portion 12 form the U-shaped draw-in groove 131 that can be connected on the side frame guide 210; Described bolt 20 is located in described the first through hole 121, and the afterbody of bolt 20 has pin-and-hole 22; Described pin 30 is located in the described pin-and-hole 22.
In the present embodiment, block key body 10 is connected on the side frame guide 210 of bogie side frame 200 by bolt 20 and pin 30, can avoid losing in the driving, the U-shaped draw-in groove 131 that the first connecting portion 12 of block key body and the second connecting portion 13 form is assembled in block key body 10 on the bogie side frame.In the practical application, at first U-shaped draw-in groove is connected on the wall of side frame guide, and bolt 20 is passed the first through hole of the first connecting portion and the through hole of side frame guide, at last pin is passed the pin-and-hole of bolt tail.When bogie truck is subject to upwards application force, the outside race 310 of taking turns 300 is blocked in the stopper section 11 of block key body, rib props up the wall of side frame guide under the U-shaped draw-in groove of the second connecting portion, carrying is because wheel produces application force between bogie side frame and the block key body to pressing down the block key body, and assurance bogie truck integral lifting hour wheel is not to breaking away from bogie truck.Owing to adopt the pin barrel bolt that the block key body is connected on the bogie side frame, both guaranteed being connected and fixed of block key body and bogie side frame, make again fitting operation simple and efficient, thereby can increase work efficiency, simultaneously, the U-shaped draw-in groove that the first connecting portion of block key body and the second connecting portion form is connected to the block key body on the bogie side frame, the application force the during lifting of carrying bogie truck, effectively guarantee bogie truck integral lifting hour wheel to not breaking away from bogie truck, the safety when having improved the railway goods train bogie lifting.
In the Vehicle Driving Cycle, can bump between the parts such as bolt, block key body, produce impact noise, right bearing detection failure identification brings adverse influence to the wheel that adopts the sound detection bearing fault for this, be the impact noise between the parts such as bolt, block key body in reducing to drive a vehicle, the embodiment of the invention is sheathed spring 40 on bolt 20 also, and Spring Card is located between bolt head and the first connecting portion 12.When the block key device is installed on the side frame guide, bolt can be penetrated in the spring, and press the header suppression spring of bolt, the afterbody of bolt is pressed into the through hole that passes correspondence on the first through hole and the side frame guide successively, when the pin-and-hole 22 on the bolt tail screw rod exposes, pin is penetrated, discharge afterwards bolt and get final product automatic clamping.Because the installation process medi-spring has certain precompressed compression, so the clamping force between pin and the side frame guide with bolt, block key body, spring is relative with bogie side frame fixes, whole mechanism is relatively fixing, and the vibration reduction and cushioning effect of spring makes between each parts not relatively play, so that reduce impact noise between these parts in the vehicle operating, thereby can reduce the impact on bearing detecting device.
For making when bogie truck lifts by crane, U-shaped draw-in groove 131 can fast and effeciently block the wall of side frame guide 210, bears the application force in when lifting, can make the groove width H of U-shaped draw-in groove 131 be slightly larger than the wall thickness h of side frame guide.
The embodiment of the invention is by mount pin in the afterbody pin-and-hole of bolt, simplified the fitting operation of block key device, avoid the problem that wastes time and energy in the bolts and nuts of the prior art assembling, accelerated installation process, but also avoided the safety problem that causes because of nut loosening; By the U-shaped draw-in groove on the block key body block key body is connected on the side frame guide, so that during the bogie truck integral lifting, lower rib carrying application force by the draw-in groove of block key body effectively guarantees wheel to not separating with bogie truck, the safety when having improved the railway goods train bogie lifting; By between bolt and block key body, being installed with spring, and fitting pin is relative with side frame guide fixing with block key body, bolt, can realize auto lock on the one hand, and be convenient to fast on-the-spot the installation, on the other hand, also can make and reduce impact noise in the vehicle operating, thereby reduce the impact of impact noise on bearing detecting device.
The embodiment of the invention also provides a kind of railway goods train bogie, comprise bogie side frame 200, bolster (not shown) and wheel are to 300, link together by suspension gear etc. between bogie side frame and the bolster, to realize vertical and horizontal backstop and vibration damping, bogie side frame 200 and wheel between 300 by realizing vertical and horizontal location to stop device in length and breadth, in embodiments of the present invention, railway goods train bogie also is provided with block key device as shown in Figure 2 above, the U-shaped draw-in groove 131 that the first connecting portion 12 of this block key device and the second connecting portion 13 form is realized clamping with the side frame guide 210 of described bogie side frame, and the through hole on described bolt 20 is arranged in turn the first through hole 121 and side frame guide is connected and fitting pin 30 connects and is fixed on the described side frame guide 210, and the stopper section 11 of the block key body 10 of described block key device is near described bottom of taking turns 300 outside race 310.Can either guarantee that by the block key device bogie truck integral lifting hour wheel pair do not separate with bogie truck, it is very simple and efficient that the block key device is installed, and is conducive to save man-hour, also reduced simultaneously the impact noise that produces in the Vehicle Driving Cycle.
The railway goods train bogie of above-described embodiment can be applicable on the railway truck.
It should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not limit it, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment or be equal to replacement technical scheme of the present invention, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solution of the present invention.
