Detailed Description
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts. In addition, the following descriptions of the orientations of the front, the rear, the left, the right, and the like are only used for describing the relative positions, and the relative orientations are changed when the reference points used as examples in the specification are changed.
Fig. 1 is a schematic view of a rail vehicle on a track. Referring to fig. 1, since the track 200 may have a change in the pitch due to wear of the track 200 during manufacture, construction or long-term use, the change of the track 200 is generally detected by the rail car 100 running on the track 200, and the detected change is transmitted back to the control center so that the control center can dispatch a person to repair or replace the track 200.
Fig. 2 is an exploded schematic view of the railcar of fig. 1. Referring to fig. 1 and 2, the rail car 100 includes a body 110 and a pair of rail wheel devices. The body 110 is in the form of a beam, and has a fixed side and a floating side at opposite sides. The rail wheel device may be further divided into a fixed-side rail wheel device 121 and a floating-side rail wheel device 122, wherein the fixed-side rail wheel device 121 is fixed to the fixed side of the body 110, and the floating-side rail wheel device 122 is assembled to the floating side of the body 110. When the rail car 100 travels on the rail 200, the floating-side rail wheel device 122 is relatively close to or far from the fixed-side rail wheel device 121 as the pitch of the rail 200 changes, thereby detecting the pitch change condition of the rail 200.
Fig. 3 is a schematic view of a floating side rail wheel assembly. Referring to fig. 1, 2 and 3, the floating-side rail wheel device 122 includes a wheel bracket 130, a guide shaft 140, a fixing block 150, an elastic member 160, a bearing 170 and a plurality of traveling members 182 and 184. The wheel bracket 130 has a first side wall 132 and a second side wall 134 opposite to each other, and the guide shaft 140 is fixed to the first side wall 132 and the second side wall 134 in a manner that the guide shaft 140 does not contact the inner bottom surface 136 of the wheel bracket 130, in other words, the guide shaft 140 is suspended with respect to the inner bottom surface 136 (refer to fig. 5 together) of the wheel bracket 130, such that the wheel bracket 130 can rotate around the guide shaft 140, that is, the wheel bracket 130 can rotate around the guide shaft 140. The guide shaft 140 passes through the fixing block 150 to connect the fixing block 150 to the wheel bracket 130, wherein the fixing block 150 has a pair of assembling protrusions 152, and the body 110 of the railway vehicle 100 has a pair of assembling recesses (not shown), so that the floating-side rail wheel device 122 is assembled by the assembling protrusions 152 of the fixing block 150 and the assembling recesses of the body 110 being fitted to each other to fix the body 110 and the floating-side rail wheel device 122 together. The elastic member 160 is sleeved outside the guide shaft 140 between the first side wall 132 and the fixed block 150, the bearing 170 is fixed in the fixed block 150 in a manner of being adjacent to the second side wall 134 and sleeved outside the guide shaft 140 penetrating the fixed block 150, and the traveling members 182 and 184 are installed under the wheel bracket 130.
As mentioned above, the elastic element 160 may be an extension spring or a compression spring as required, wherein the elastic element 160 of the embodiment is a compression spring, one end of the elastic element 160 is connected to the first sidewall 132, and the other end of the elastic element 160 abuts against the fixing block 150. More specifically, the end of the elastic member 160 connected to the first sidewall 132 is fixed by forming a stopper (e.g., a groove) in the wheel bracket 130.
In addition, the running members 182 and 184 refer to components capable of generating relative movement while contacting the reference object, and may be selected as rollers, or a combination of rollers and rollers as required, wherein some of the running members 182 run above the track 200 to enable the rail car 100 to move relative to the track 200, and the rest of the running members 184 run along the inner side of the track 200 to measure the change of the track pitch. For example, the traveling member 182 traveling above the rail 200 in the present embodiment is a roller, and the inner traveling member 184 along the rail 200 is a roller, and the axial direction of the roller is parallel to the height direction of the rail 200.
Fig. 4a and 4b are schematic views of the body and the rail-wheel unit fixed together via a locking attachment, wherein fig. 4b is a sectional view taken along a line a-a of fig. 4a, and unnecessary components are omitted from fig. 4 b. Referring to fig. 2, fig. 3, fig. 4a and fig. 4b, the rail car 100 further includes a plurality of locking accessories 180, wherein the locking accessories 180 pass through the body 110 from above the fixing block 150 and are locked into the fixing block 150, so that the body 110 and the fixing block 150 are fixed together. In short, the use of the lock attachment 180 further restricts the fixing block 150 from moving horizontally or vertically with respect to the body 110.
As described above, the body 110 is coupled to the fixed block 150 so as to be rotatable with respect to the wheel bracket 130 about the guide shaft 140 as a rotation axis, or the body 110 is coupled to the fixed block 150 so as to be movable with respect to the wheel bracket 130 along the axis direction of the guide shaft 140 within the range of the elastic force of the elastic member 160.
In addition, the rail car 100 further includes a plurality of stoppers 190, and the stoppers 190 are, for example, studs, which can pass through the wheel bracket 130 from the outer side of the second sidewall 134 of the wheel bracket 130 to abut against the fixing block 150. The distance between the fixing block 150 and the second sidewall 134 can be adjusted by the depth of the stopper 190 penetrating into the second sidewall 134. In addition, the second sidewall 134 further has a groove 134a, and the rail car 100 may further include an adjusting block 192 disposed in the groove 134a, and the limiting member 190 passes through the second sidewall 134 and then further passes through the adjusting block 192 to abut against the fixing block 150. The adjustment block 192 may serve to increase the structural strength.
The stoppers 190, which pass through the wheel bracket 130 from the outer side of the second sidewall 134 and abut against the fixing block 150, do not fix the wheel bracket 130 and the fixing block 150 to each other, i.e., the wheel bracket 130 and the fixing block 150 can be displaced relative to each other.
Referring to fig. 1, when the track 200 is to be inspected, the railcar 100 is placed on the track 200, and the railcar 100 is pushed along the traveling direction on the track 200. By using the running members 182, 184, the railcar 100 can run smoothly on the track 200.
Referring to fig. 1, 2 and 3, as the rail car 100 moves relative to the rail 200, when the top surface 202 of the rail 200 is convex or concave, the front running member 182 experiences the change to the top surface 202, and the rear running member 182 may still be on the top surface 202 of the flat rail 200. For example, when the traveling unit 182 positioned in front passes through the protrusion, since the fixing block 150 is fixed to the body 110, while the front end of the wheel bracket 130 is upward along with the protrusion, the rear end of the wheel bracket 130 has a slight amount of change in the downward direction by acting as the rotation axis of the wheel bracket 130 through the guide shaft 140 penetrating the fixing block 150. Incidentally, the running member 182 continuously contacts the top surface 202 of the rail 200 to run, and the rotation of the wheel bracket 130 does not affect the running of the rail car 100.
In contrast, when the traveling member 182 located at the front side first undergoes the recess, the front end of the wheel bracket 130 is slightly rotated downward by the guide shaft 140 serving as the rotation axis of the wheel bracket 130, the rear end of the wheel bracket 130 is slightly rotated upward to reach the balance, and the traveling member 182 for the rail car 100 to travel on the top surface 202 of the rail 200 is continuously contacted to the top surface 202 of the rail 200.
It will be appreciated that the floating side rail wheel assembly 122 can adapt to changes in the top surface 202 of the rail 200.
On the other hand, when the rail car 100 is placed on the rail to perform rail 200 detection, the fixed-side rail wheel device 121 and the floating-side rail wheel device 122 are maintained at substantially the same distance. In a normal condition (i.e., when there is no change in the track pitch), the traveling members 184 of the fixed-side rail wheel device 121 and the floating-side rail wheel device 122 traveling along the inner side of the track 200 maintain the same distance. When the track pitch is changed, since the fixed side and the floating side of the body 110 maintain the same distance, by the arrangement of the fixed block 150, the wheel bracket 130, the elastic member 160, the guide shaft 140 and the bearing 170 of the floating-side track wheel device 122, wherein the wheel bracket 130 may have a runout along the axial direction of the guide shaft 140 with respect to the fixed block 150 as the running member 184 moves, the running member 184 running along the inner side of the track 200 in the floating-side track wheel device 122 may relatively approach or separate from the running member 184 running along the inner side of the track 200 in the fixed-side track wheel device 121 to adapt to the change of the pitch of the track 200.
It should be noted that the wheel support 130 of the fixed-side rail wheel device 121 is fixed relative to the body 110, that is, the wheel support 130 cannot swing left or right relative to the body 110, but the wheel support 130 of the floating-side rail wheel device 122 can swing left or right relative to the body 110 to achieve the effect of adapting to the change of the rail pitch.
When the track pitch is narrowed, the traveling member 184 of the floating-side track wheel device 122 traveling along the inner side of the track 200 is relatively close to the traveling member 184 of the fixed-side track wheel device 121 traveling along the inner side of the track 200. More specifically, the fixing block 150 of the floating-side rail-wheel device 122 is fixed to the body 110, so that the fixing block 150 does not move horizontally or vertically relative to the body 110, and therefore, the moving member 184 of the floating-side rail-wheel device 122 is relatively close to the moving member 184 of the fixed-side rail-wheel device 121 by the change of the distance, the wheel bracket 130 is driven by the moving member 184 to be close to the fixed-side rail-wheel device 121 along the axial direction of the guide shaft 140, and the first side wall 132 of the wheel bracket 130 moves toward the fixing block 150 along with the movement of the wheel bracket 130, thereby compressing the elastic member 160. At this time, the stopper 190 inserted into the wheel bracket 130 from the outside of the second side wall 134 of the wheel bracket 130 and abutting against the fixing block 150 is separated from the fixing block 150.
As can be seen from the above, the wheel bracket 130 linked to the traveling member 184 has a margin movable relative to the fixed block 150 by the arrangement of the wheel bracket 130, the guide shaft 140 and the elastic member 160, so that the wheel bracket can adaptively match the narrowing of the track pitch without applying stress concentration on the components due to the narrowing of the pitch of the track 200, thereby avoiding the damage of the components.
It should be noted that the traveling member 184 traveling along the inner side of the rail 200 continuously travels against the inner side of the rail 200 by the elastic force of the elastic member 160.
Then, by the elastic restoring force of the elastic member 160, when the track pitch gradually restores to the original width, the wheel bracket 130 returns to the original position, and the retaining member 190 penetrating through the second sidewall 134 of the wheel bracket 130 abuts against the fixing block 150 again.
On the contrary, when the track pitch is widened, the traveling member 184 of the floating-side rail-wheel unit 122 traveling along the inner side of the track 200 can relatively move away from the traveling member 184 of the fixed-side rail-wheel unit 121 traveling along the inner side of the track 200 while continuously continuing to travel against the inner side of the track 200 by the elastic force provided by the elastic member 160.
As can be seen from the above, the rail wheel apparatus of the present invention has a configuration for adapting to the rail variation, so that when the rail car 100 performs rail detection, the traveling members 182 and 184 can continuously adapt to the variation of the rail 200 and travel along the rail 200, and the rail wheel apparatus having the configuration can absorb the tolerance of the rail width direction and the angle of the rail top surface, so that the rail car 100 using the rail wheel apparatus can obtain an accurate detection result.
Incidentally, in other embodiments, the fixing block 150 may have a pair of assembling recesses 154, and the body 110 of the rail car 100 may have a pair of assembling protrusions (not shown), and the assembling protrusions and the assembling recesses 154 are matched with each other to enable the body 110 and the fixing block 150 to be assembled together, as shown in fig. 5.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
