Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height measuring device for various members and equipment provided under the floor of a railway vehicle.

[0002]

2. Description of the Related Art In a railway vehicle, after traveling a certain distance, the outer periphery of the wheel is ground to have a perfect circular shape periodically or appropriately to correct uneven wear of the wheel. In the wheel whose outer periphery is ground in this way, the axle is naturally lowered according to the ground amount (usually about several millimeters).

On the other hand, under the floor of the vehicle, various devices and members such as an obstacle barrier, an ATS car top, and a waste tank are provided. For safety or equipment maintenance, these equipments and members are standardized such that they are arranged at a certain height or higher from the rail. Therefore, each time the wheel is ground as described above, it is necessary to check whether or not the height of the underfloor equipment of the vehicle satisfies a predetermined reference value.

Conventionally, when measuring the height of such under-floor equipment, etc., a timber and scale are used to mount the timber over both rails under the floor of the vehicle so that an operator can enter under the floor. The height from the lever bar to the bottom of the equipment under the floor was measured on a scale.

[0005]

However, in the conventional height measuring method using the timber and the scale, the worker has to be under the floor of the vehicle and the scale of the scale is difficult to read because of an unnatural posture. The work was both tedious and dangerous. In addition, if there are equipment to be measured under the floor on both the left and right sides of the vehicle, it may be necessary to bypass one side of the vehicle after the measurement and go around to the other side to perform the measurement work. It was efficient and time consuming.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and is capable of easily measuring the height of underfloor equipment of a vehicle with a simple structure without the operator having to go under the floor of the vehicle. The purpose is to provide a device.

[0007]

In order to achieve the above object, a height measuring device for underfloor equipment for railway vehicles according to the present invention is mounted on both rails under the floor of the vehicle to be measured. A main body for setting a horizontal reference for measurement, a guide member protruding vertically upward from the upper surface of the main body with the main body placed on a rail, and a scale slidable along the main body and the guide member. It is characterized in that the scale end portion on the main body outside the rail is slid horizontally so that the opposite end portion of the scale protrudes from the upper end of the guide member and can be slid vertically. .

In a preferred embodiment, two or more guide members are provided on one surface of the main body, and two or more scales corresponding to the respective guide members are provided with their end portions at the same end of the main body. It is characterized by being arranged on the part side.

In a further preferred embodiment, the main body is substantially a quadrangular prism body, and the guide members are provided at different positions on two adjacent side surfaces of the quadrangular prism body.

[0010]

In the state where the main body of the measuring device is placed on both rails and the guide member is arranged directly below the device to be measured, the worker works from the outside of the vehicle to the scale end on the end of the main body. Is slid so that the opposite end thereof is projected from the guide member and brought into contact with the lower end surface of the device. By making the scale graduation on the end of the main body correspond to the height of the scale end protruding from the guide member in advance, the worker can read the scale graduation on the end of the main body from the outside of the vehicle to determine the height of the vehicle underfloor equipment. Can be measured.

For example, two guide members are provided on the main body,
If two scales are provided so that their ends are arranged on the same side of the main body, the heights of two underfloor devices can be measured from one side of the vehicle at the same time.

If a guide member and a corresponding scale are provided at different positions on two adjacent side surfaces of the rectangular prism, the directions can be changed so that the side surfaces of the rectangular prism are sequentially arranged on the upper surface. The height of the underfloor equipment at different positions in the vehicle width direction can be measured by rotating the square column and changing its direction while the worker is at the same place.

Further, FIG. 2 is an exploded perspective view for explaining the configuration of a part of the apparatus of FIG.

In this embodiment, a first scale guide 1, a second scale guide 2 and a third scale guide 3 which will be described later are provided so as to project on two adjacent side surfaces of a main body 4. . The main body 4 is a substantially rectangular rod-shaped member made of an extruded body such as aluminum, and its length is equal to or larger than the width between rails of a vehicle to be measured. The first and second scale guides 1 and 2 are provided on one side surface of the main body 4 so as to vertically project from the side surface of the main body, and the first and second scale guides are provided on the adjacent side surfaces perpendicular to the side surface of the main body. 1,
A third scale guide 3 is provided so as to be vertically displaced from the side surface of the main body by shifting the position (position in the longitudinal direction of the main body) from 2. In this example, for example, the total length of the main body is 2,200 mm
The distance from the end of the main body 4 on the side of the measurer (on the left side of the figure) is 460 mm for the first scale guide 1, 1,510 mm for the second scale guide 2, and 2,120 mm for the third scale guide 3. . Such a distance is determined according to the location of the vehicle underfloor equipment to be measured. Each of the scale guides 1, 2, and 3 is made of, for example, an extruded body having an I-shaped cross section, and the first, second, and third scale guides are formed along the central groove.
The scales 5, 6 and 7 are provided. Each scale guide is not limited to a metal member having an I-shaped cross section, and may have any shape or material as long as it has a guide plane on which the scale can slide. The shape and material of the main body 4 are not limited to those shown in FIGS. 1 and 2 as long as they are substantially quadrangular prisms.

The scales 5, 6 and 7 are arranged along the respective side faces of the main body 4 and are bent at the roots of the scale guides so as to project vertically from the respective side faces along the scale guides.
Each scale 5, 6, 7 is slidable along the main body surface and the scale guide surface. That is, each scale 5,
The end portions 5a, 6a, 7a of 6, 7 are connected with arrows A1, B1, C1.
When the scale is horizontally moved as shown in FIG. 5, the other ends of the scales projecting from the upper ends of the scale guides 1, 2, 3 move up and down as indicated by arrows A2, B2, C2.

The operation-side end 5a of the first scale 5 is arranged at the measurer-side end of the main body 4, and the operation-side end 6a of the second scale 6 is inside the first scale guide 1 (in the figure). (Right side)

You may make it easy to see the scale scale.

Next, a method of using the measuring device having the above structure will be described. First, when measuring the height of an underfloor device near one side of the vehicle, the main body 4 is placed over both rails and the first scale guide 1 is arranged directly below the device to be measured. In this state, the operator operates the end 5a of the scale 5 from the outside of the vehicle and slides it until the other end of the scale 5 protruding above the scale guide 1 comes into contact with the lower surface of the device. The distance from the rail in the height direction of the scale end is a reference position (marked in advance) directly marked on the main body 4 such as an acrylic plate (not shown) with scale on the scale end 5a on the operation end side of the main body 4 in advance. The scale of the bottom position of the underfloor equipment can be measured by reading the scale at the reference position by associating it with the scale of (No).

When measuring the height of the equipment in the middle part under the floor of the vehicle, pull out the main body 4 somewhat to the outside of the vehicle,
The second scale guide 2 is placed directly below the instrument to be measured. At this time, the end of the main body 4 (the right end in the figure) is on the rail, and the end 6a of the second scale 6 is outside the vehicle. In this state, similarly to the case where the first scale 5 is used, the end 6a of the second scale 6 is operated to bring the other end of the scale into contact with the bottom surface of the device, and the scale on the end 6a side at that time is read. Measure the height of the bottom of the device.

When measuring the height of the underfloor equipment near the opposite side of the vehicle, the main body 4 is rotated to change the direction of the main body 4 so that the third scale guide 3 projects above the rail. Put on. In this state, similarly to the above, the end 7a of the third scale 7 is operated to bring the other end of the scale into contact with the bottom surface of the device, and the scale on the end 7a side at that time is read to measure the height of the bottom surface of the device. To do.
