DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] Since the density of steel blades is relatively large, in order to reduce the deadweight of the steel blades and the impact of wind force in coastal areas on the steel blades, thereby reducing the deformation speed of the steel blades, a railway locomotive vehicle limit gauge suitable for outdoor use in coastal areas is designed.

[0036] This design is based on the original railway locomotive vehicle limit gauge (i.e., it includes two parts, the upper gauge and the lower gauge, a steel structure frame composed of columns 9 and beams, and adjustable reset steel blades symmetrically distributed on the inner side of the steel structure frame.), according to the material and external dimensions of the steel blades, and with reference to the local wind force in the coastal areas, the idea of ​​digging holes in the steel blades is adopted, as shown in the figure. The shapes of the holes dug in different coastal areas may be different. In this way, on the one hand, the deadweight of the steel blades can be reduced under normal use conditions, and on the other hand, a wind flow channel is formed to minimize the impact of wind force on the steel blades, thereby achieving the purpose of reducing the deformation speed of the steel blades.

[0037] With this device, the outer contour measurement of railway locomotives can be realized outdoors in coastal areas.

[0038] like Figures 1 to 6 As shown, an outdoor railway locomotive vehicle gauge for coastal areas includes a column 9 and an upper crossbeam 22, wherein two columns 9 are provided, and the two columns 9 are vertically arranged on both sides of the locomotive track, and the two ends of the upper crossbeam 22 are respectively connected to the tops of the two columns 9;

[0039] The two columns 9 are connected to the side close to the locomotive track and the lower part of the upper cross beam 22 with blades, and the blades are movably connected to the columns 9 and the upper cross beam 22 respectively;

[0044] A travel switch 14 is also provided on the column 9 and the upper cross beam 22, and a push rod 141 of the travel switch 14 is connected to the limit plate.

[0045] The column 9 is provided with a wheel outer upper limit plate 8, a side lower limit plate 10, a side upper limit plate 15, and a side oblique lower limit plate 17 in sequence from bottom to top on the side close to the locomotive track. The wheel outer upper limit plate 8, the side lower limit plate 10, the side upper limit plate 15, and the side oblique lower limit plate 17 are connected to the column 9 through corresponding adjustment plates.

[0046] The upper cross beam 22 is provided with a lateral inclined upper limit plate 18, an upper horizontal limit plate 23, an upper horizontal limit plate 23, and a lateral inclined upper limit plate 18 in sequence, and the lateral inclined upper limit plate 18 and the upper horizontal limit plate 23 are connected to the upper cross beam 22 through corresponding adjustment plates.

[0050] The two ends of the second connecting plate 25 are respectively fixedly connected with the shaft sleeve of the first rotating shaft 27 and the shaft sleeve of the second rotating shaft 28;

[0051] The end surface of the third connecting plate 26 is fixedly connected to the limiting plate, the first edge of the third connecting plate 26 is a free end, and the second edge opposite to the first edge is connected to the shaft core of the second rotating shaft 28 through the connecting port of the shaft sleeve of the second rotating shaft 28.

The wheelset inner lower limit bracket 1 is connected to the ground, and the wheelset inner lower limit plate 3 is connected to the wheelset inner lower limit bracket 1 through the wheelset inner lower limit adjustment plate 2.

[0053] The surface of the boundary plate is sprayed with yellow and black zebra crossing coating.

[0054] During specific use, the positions of the blades arranged on the column 9 and the upper crossbeam 22 are adjusted according to specific test requirements to ensure that the setting positions of each blade meet the requirements of the railway locomotive vehicle limit regulations. At the same time, the blade includes a limit plate and an adjustment plate. The limit plate and the adjustment plate both include multiple ones, such as the wheel outer side upper limit plate 8, the side lower limit plate 10, the side upper limit plate 15, and the side oblique lower limit plate 17 arranged on the column 9. The wheel outer side upper limit plate 8, and the above limit plates are all provided with corresponding adjustment plates. The limit plates are respectively installed on the column 9 and the upper crossbeam 22 through the adjustment plates. The limit plates and the adjustment plates are movably connected through a rotating shaft. At the same time, the wheel outer side upper limit plate 8 is also connected to the wheel outer side lower limit plate 7, which is used to detect the wheel and the outer side of the track;

[0055] The rotating shaft mentioned here includes a first connecting plate 24, a second connecting plate 25, a third connecting plate 26, a first rotating shaft 27 and a second rotating shaft 28. The second connecting plate 25 is arranged between the first connecting plate 24 and the third connecting plate 26. The first rotating shaft 27 and the second rotating shaft 28 both include a shaft sleeve and a shaft core. The shaft core is arranged in the shaft sleeve, and the shaft core is rotatably connected with the shaft sleeve.

[0056] The end surface of the first connecting plate 24 is fixedly connected to the adjustment plate, the first edge of the first connecting plate 24 is a free end, and the second edge opposite to the first edge is connected to the shaft core of the first rotating shaft 27 through the connecting port of the shaft sleeve of the first rotating shaft 27;

[0059] In actual use, when a locomotive passes, the blade will swing due to the fact that the locomotive's external dimensions do not meet the requirements. Since the locomotive may drive towards the limit gauge from different directions of the track, it is necessary to ensure that the shaft between the limit plate and the adjustment plate can rotate in different directions when the car touches the limit plate to reduce damage to the blade. The specific structure of the shaft is shown in the figure;

[0060] At the same time, in order to know whether the locomotive has touched the blade, a travel switch 14 is provided. The push rod 141 of the travel switch 14 (that is, the trigger unit of the travel switch 14) is connected to the two sides of the limit plate. Travel switches 14 are provided on both sides of the limit plate. When the vehicle approaches from different directions, once it touches the blade, the travel switch 14 will be triggered as the blade rotates. By connecting the travel switch 14 to the monitoring system, it can be known that the locomotive has touched the blade. At the same time, when in use, a travel switch 14 is provided for each blade. Therefore, according to the signal fed back to the monitoring system by the travel switch 14 at different positions, it can be known which position of the locomotive to be tested does not meet the requirements.

[0061] For ease of understanding, the structure of the blade between the column 9 and the rail is the same in this solution, and both adopt Figure 3-Figure 5 Institutions shown.
