Detailed description of the invention
Core of the present utility model is to provide a kind of magnetic-levitation train track joint for track panel, and this magnetic-levitation train track joint for track panel significantly can reduce the impact of track to support wheel on train.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See the structure chart of magnetic-levitation train track joint for track panel under the first detailed description of the invention that Fig. 3-Fig. 8, Fig. 3 provide for the utility model; Fig. 4 is the sectional view of Fig. 3; The magnetic-levitation train track joint for track panel that Fig. 5 provides for the utility model under the first detailed description of the invention by schematic diagram during support wheel; The structure chart of magnetic-levitation train track joint for track panel under the second detailed description of the invention that Fig. 6 provides for the utility model; Fig. 7 is the sectional view of Fig. 6; The magnetic-levitation train track joint for track panel that Fig. 8 provides for the utility model under the second detailed description of the invention by schematic diagram during support wheel.
The magnetic-levitation train track joint for track panel that the utility model embodiment provides, comprise two pieces of adjacent sections of track 1, also comprising can for the transition key 6 of support wheel 3 process of train, the abutting end of two adjacent sections of track 1 all offers keyway 7, transition key 6 is connected in two keyways 7, and the upper surface 8 of transition key 6 is concordant with the sled supporting surface 5 of the section of track 1.
The magnetic-levitation train track joint for track panel that the utility model embodiment provides, compared to track of the prior art, keyway 7 is all offered at the abutting end of two sections of track 1, transition key 6 is connected in two keyways 7, and the upper surface 8 of transition key 6 is concordant with the sled supporting surface 5 of the section of track, thus when the rail gap 2 of support wheel 3 between the section of track and the section of track, support wheel 3 can be walked at the upper surface 8 of transition key 6, then effectively reduce the impact of rail gap 2 pairs of train support wheels 3.
Further, fix for the ease of the installation between transition key 6 and the section of track 1, mount pad can being connected with in the bottom of transition key 6, two sections of track 1 being provided with the first installing hole 9 for being connected with mount pad, mount pad be provided with the second installing hole 10 matched with the first installing hole 9.
In the embodiment that the first is concrete, the first installing hole 9 is counter sink, and the section of track 1 and mount pad are fixed together by bolt group, in the second detailed description of the invention, the first installing hole 9 is screw hole, the section of track 1 and mount pad is fixed together with screw.
Because the width of rail gap 2 differs, second installing hole 10 can be set to strip hole to adapt to different rail gap width, as being specifically as follows waist-shaped hole, then because screw can move along the length direction of the second installing hole 10, then go for the width of different rail gaps 2 with the transition key 6 of mount pad.
Each section of track 1 can be provided with two the first installing holes 9, and also can be provided with three the first installing holes 9, the quantity of installing hole is unrestricted.
The length of keyway 7 can be the half of the length of transition key 6, can ensure that transition key 6 is connected in two keyways 7 fully.
In order to ensure that support wheel 3 is not subject to the impact of keyway 7 at width, the width of support wheel 3 is it axially, and the width of keyway 7 is set to the width being less than support wheel 3.
After transition key 6 being installed in keyway 7, between the end meeting of transition key 6 and the section of track 1, there is certain gap, by uncontrollable factor impact likely transition key 6 its upper surface after installing can slightly exceed sled supporting surface 5, then can there is chamfering 11 at the end opens of the upper surface 8 of transition key 6, even if the end of the upper surface 8 of transition key 6 is slightly to having a down dip, thus support wheel 3 is avoided to be subject to unnecessary impact in the gap between transition key 6 and the section of track 1.
Above magnetic-levitation train track joint for track panel provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
