Description

  The present invention relates to a maintenance / construction vehicle traveling on a track.

  Railway live track work and track maintenance work are carried out while running a construction vehicle on the track. By the way, the distance between the two left and right rails that make up the track, that is, the gauge (track gauge or simply gauge) is 1067 mm for the narrow gauge, 1372 mm for the middle gauge, and 1435 mm for the standard gauge. Standard gauge is applied.

  In conventional track maintenance work, JR companies and private railway companies had to prepare construction vehicles according to their own gauges and use them for construction. Therefore, in some cases, it is necessary to prepare a narrow-gauge vehicle, a middle-gauge vehicle, and a standard-gauge vehicle. In addition to increasing the purchase cost of the construction vehicle, it is necessary to replace the construction vehicle according to the gauge. In addition, there are many problems such as the need to secure a stop space for a plurality of construction vehicles.

  Here, in Patent Document 1, a wheel shaft frame supported by a shaft portion and a support portion is provided between both side ends of the left and right side beams of the bogie frame, and a bearing box that supports both side journals of independent wheels is provided via parallel links. A trolley-side device that is suspended on the left and right support parts of the wheel axle frame and can move independent wheels to the narrow gauge side fixed position and the wide gauge side fixed position by the rotational displacement of the parallel links, and the rail ends of the narrow track and the wide track A track-side device is disclosed in which a wheel support mechanism is provided on the outside of the wheel guide mechanism, and a support base for supporting the wheel frame frame is provided along the track.

  According to this track side device, it is possible to deal with a plurality of types of gauges with a single carriage, and it is also possible to deal with gauges other than the above-described gauges.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a construction vehicle that can handle a plurality of different gauges with a simple configuration.

  In order to achieve the above object, a maintenance / construction vehicle according to the present invention is a construction vehicle traveling on a track, and the construction vehicle has axles with wheels on the left and right, The vehicle has a hollow, the left and right wheels are fixed to the axle through the hollow through the axle, and the axle has a pair of annular stoppers on the left and right, respectively. Is sandwiched between the pair of stoppers and an annular collar disposed on either the left or right side of the wheel, and a fixed position of the wheel sandwiched between the pair of stoppers and the collar with respect to the axle. It is possible to freely adjust the distance between the left and right wheels by changing.

  The maintenance / construction vehicle of the present invention allows a hollow wheel to pass through the axle so that the wheel can move with respect to the axle, and a pair of annular stoppers and annular collars are provided on the left and right sides of the axle, respectively. The left and right wheels are sandwiched between a pair of stoppers and collars that are unique to each other, and they are fixed in place with respect to the axle, making it possible to easily adjust the gauge between the left and right wheels. It is a thing.

  That is, instead of adjusting the gauge with a complicated structure adjusting means including a spring, a link mechanism, etc., the stopper, the collar, and the wheel are moved relative to the axle and fixed at a desired position. It is a vehicle that can cope with a plurality of types of gauges by the gauge adjusting means.

  For example, among the pair of annular stoppers on the left and right sides of the axle, the position of the inner (axle center side) stopper is fixed according to the narrow gauge width of the gauge. On the other hand, the stopper and collar on the outer side (axle end side) are movable with respect to the axle. When making the left and right wheels correspond to the narrow gauge gauge, position the left and right wheels in contact with the left and right inner stoppers, respectively, place an annular collar on the outside of each wheel, and place the outer stopper on the outside of this collar. By arranging the outer stopper and fixing the outer stopper to the axle, a construction vehicle corresponding to a narrow gauge can be configured.

  On the other hand, when making the left and right wheels correspond to the middle gauge gauge or the standard gauge gauge, the collar is brought into contact with the inner stopper, the wheel is arranged outside the collar, and the outer stopper is arranged outside the wheel. By fixing the outer stopper to the axle, a construction vehicle corresponding to the middle gauge gauge or the standard gauge gauge can be configured.

  Here, the color is composed of a first color and a second color having two different widths, and both the first and second colors are arranged on either the left or right side of the wheel, or A form in which the first collar and the second collar are respectively disposed on the left and right sides of the wheel can be exemplified.

  By applying two types of collars with different widths to the left and right wheels, it is possible to easily handle narrow gauge, medium gauge, and standard gauge gauges.

  Specifically, for narrow gauge gauges, an axle equipped with wheels corresponding to the narrow gauge gauge can be configured by arranging two types of collars and an outer stopper on the outside of the wheel, and the relatively narrow first gauge. An axle equipped with a wheel corresponding to the middle gauge is constructed by arranging one collar and outer stopper on the outside of the wheel, and arranging a relatively wide second collar and inner stopper on the inside of the wheel. it can. Furthermore, an axle equipped with a wheel corresponding to a standard gauge gauge can be configured by arranging two kinds of collars and an inner stopper inside the wheel and arranging only the outer stopper outside the wheel.

  In this embodiment, two types of colors are applied to the left and right wheels, but it is needless to say that three or more different colors having different widths may be applied as necessary. is there.

  Further, it is preferable that the stopper, the first collar, and the second collar are composed of two half pipes, and the two half pipes are fixed with pins or screws.

  When adjusting the position of the stopper and collar, they can be attached to and detached from the axle, and the stopper and collar are both composed of two halves to facilitate positioning and fixing to the axle. Two half pipes are installed at the position and fixed with pins or screws.

  The maintenance / construction vehicle in the present invention may be a vehicle in which heavy machinery such as various cranes includes two or more sets of wheels and axles configured as described above, or a carriage including two or more sets of wheels and axles configured as described above. It may be a vehicle on which heavy machinery such as various cranes is mounted.

  For example, in the case of a construction vehicle in which heavy equipment is mounted on a carriage, the truck with no heavy equipment is lifted by jacking up, etc., and the left and right wheels are positioned so as to correspond to the gauge, and a pair of stoppers and collars By adjusting the wheel, the wheel can be fixed to the axle, and a truck corresponding to the gauge can be jacked down on the rail, and heavy equipment can be mounted on this truck to perform track maintenance work.

  As can be understood from the above description, according to the maintenance and construction vehicle of the present invention, a hollow wheel is passed through the axle so that the wheel is movable with respect to the axle. An annular stopper and an annular collar are arranged, and the left and right wheels are sandwiched between a pair of unique stoppers and collars, respectively, and these are fixed at a predetermined position with respect to the axle. The vehicle can handle multiple types of gauges.

It is the exploded view which decomposed | disassembled the axle shaft, the outer stopper, and two types of collars. It is an assembly drawing of a stopper. It is a front view of the wheel and axle of a standard gauge. It is a front view of the wheel of a middle gauge, and an axle. It is a front view of a narrow gauge wheel and an axle.

  Embodiments of a maintenance / construction vehicle according to the present invention will be described below with reference to the drawings. The maintenance / construction vehicle in the illustrated example shows a cart that can be loaded with heavy machinery such as a crane, but the heavy machinery itself may be a construction vehicle equipped with wheels and an axle that is a characteristic configuration of the present invention. . Further, although the color in the illustrated example is composed of two kinds of first and second colors having different widths, it is needless to say that three or more kinds of colors having different widths may be applied. .

(Embodiment of vehicle for maintenance and construction)
FIG. 1 is a front view of an embodiment of a vehicle for maintenance and construction according to the present invention, FIG. 2 is an exploded view of an axle, an outer stopper, and two types of collars, and FIG. 3 is an assembled view of the stopper. is there.

  A maintenance / construction vehicle 10 shown in the figure is composed of a pedestal 5 and two or more axles 1 rotatably mounted below the pedestal 5, and the axle 1 has a pair of stoppers 3 and collars 4 and wheels 2. It is fixed. In actual track maintenance work or the like, a suitable heavy machine (not shown) is mounted on the pedestal 5 constituting the construction vehicle 10, and construction is performed while the construction vehicle 10 travels on the left and right rails R <b> 1.

  Both the left and right wheels 2 have a hollow, and the axle 1 penetrates through the hollow, so that the wheel 2 is movable with respect to the axle 1 as shown in FIG. 2 (X direction). The wheel 2 is fixed to the axle 1 in a state where the shaft friction fastener 22 is fitted in the outer recess 21 formed in the wheel 2.

  An annular inner stopper 32 is fixed to the left and right inner sides of the axle 1, and two annular first and second collars 41 and 42 (both of which have different widths) are disposed on the outer sides of the respective inner stoppers 32. 4), the wheel 2 is disposed outside the first collar 41, the outer stopper 31 is disposed outside the wheel 2, and the outer stopper 31 is fixed to the axle 1. ing.

  The first collar 41 is relatively thin compared to the second collar 42, so that the left and right wheels 2 can correspond to a plurality of types of gauges by their width and their arrangement with respect to the wheels 2. It is configured.

  In FIG. 1, the tracks of the two left and right rails R1 indicate standard gauges, and the two left and right rails R2 on the inner side indicate intermediate tracks.

  The outer stopper 31, the inner stopper 32, and the first and second collars 41 and 42 are each composed of two half pipes. Here, the configuration of the outer stopper 31 will be described.

  As shown in FIG. 3, the outer stopper 31 is composed of two half pipes 31a. These half pipes 31a are positioned at predetermined positions of the axle 1, and pins 31b are provided in pin grooves communicating with both. An annular outer stopper 31 is formed by fitting. In addition, there are various methods for assembling the half pipes 31a other than the example shown in the figure. In place of the pins, screws are screwed to fix both, and a recess is provided at the end of one half pipe. An example is a mode in which the convex portion at the end of the other half pipe is fitted into the concave portion.

  Thus, in the illustrated method for fixing the wheel 2 to the axle 1, the wheel 2 can freely slide relative to the axle 1, so that the gauge between the left and right wheels 2 can be adjusted as desired. In the conventional maintenance / construction vehicle, since the wheels are fixed at the same position with respect to the axle, the configuration in which the wheels 2 are slidable with respect to the axle 1 is new and innovative, although the configuration itself is simple. It can be said to be a technical idea.

  Further, since the outer and inner stoppers 31 and 32 and the first and second collars 41 and 42 are both formed of a half pipe, they can be easily attached and detached, and the gauge can be changed quickly. be able to.

  Therefore, a single maintenance / construction vehicle 10 can handle a variety of gauges, including conventional narrow gauges, medium gauges, and standard gauges, as well as new gauges. Is possible.

  The standard gauge shown in FIG. 4 has a gauge of 1435 mm. In order to correspond to this gauge, inner stoppers 32 are fixed to the left and right inner sides with respect to the axle 1, and the first and second collars 41 are arranged outside these. , 42 are disposed in close contact with each other, the wheel 2 is disposed outside the first collar 41, and the outer stopper 31 is disposed and fixed outside the wheel 2 for maintenance and construction corresponding to a standard gauge. It is a vehicle.

  On the other hand, the gauge shown in FIG. 5 has a gauge of 1372 mm. In order to correspond to this gauge, the inner stoppers 32 are fixed to the left and right inner sides with respect to the axle 1, and the second collar 42 is placed on the outer sides. The wheel 2 is disposed outside the second collar 42, the first collar 41 is disposed outside the wheel 2, and the outer stopper 31 is disposed and fixed outside the first collar 41. Therefore, it is a maintenance / construction vehicle compatible with the middle gauge.

  Further, the narrow gauge shown in FIG. 6 has a gauge of 1067 mm. In order to correspond to this gauge, inner stoppers 32 are fixed on the inner sides of the axle 1 on the left and right sides, and the wheels 2 are disposed on the outer sides thereof. The first and second collars 41 and 42 are disposed in close contact with the outer side of the wheel 2 and the outer stopper 31 is disposed and fixed on the outer side of the first collar 41 for maintenance and construction corresponding to a narrow gauge. It is a vehicle.

  Although illustration is omitted, the position adjustment of the wheel 2 corresponding to the standard gauge, the middle gauge, and the narrow gauge can be performed by jacking up a plurality of locations of the maintenance / construction vehicle 10 from below, The first and second collars 41 and 42 are unpinned, the wheel 2 is slid to a predetermined position on the axle 1, the stopper 3 and the collar 4 are fixed at the predetermined position on the axle 1, and then jacked down. It can be done by the method.

  According to the illustrated maintenance / construction vehicle 10, the wheel width corresponding to various gauges can be adjusted quickly and easily, so there is no need to prepare a vehicle for each track with different gauges. Thus, the cost required for track maintenance can be greatly reduced.

  Further, since a plurality of types of construction vehicles are not required, the storage space for the construction vehicles can be reduced, and the effect is remarkable particularly in urban areas where it is difficult to secure the site.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
