The height-adjustable sleeper of the present invention can be used in a newly installed track, but can also be used in exchange for a sleeper used in a conventional track. However, the height-adjustable sleeper of the present invention adopts steel as a material for manufacturing because of its high dimensional accuracy and mass production capability, and the ability to manufacture high-strength products. It is advantageous. However, when steel products are used on a conventional road bed constructed using crushed stone, rusting and the like are likely to occur due to scratches on the sleeper surface due to movement of crushed stone. Therefore, when selecting a material for production, it is desirable to evaluate the material in consideration of the use environment and the like. In addition, it is recommended that such steel products be used on roadbeds composed of concrete slabs that are not easily damaged. In this case, track maintenance is further facilitated and the service life of the equipment is also increased. There is an advantage that it becomes longer.

  The height-adjustable pillow according to the present invention is provided with an electrically insulating connecting member at the center thereof, and two connecting arms are formed at both ends thereof. These pre-assemblies have the same structure, so that the shapes are completely symmetrical and have functionally equivalent performance. Therefore, handling is also completely symmetric and extremely easy to operate. In addition, since the rails installed on the sleepers are electrically insulated from each other, there is no danger of confusing the signals that protect the safety of train travel, and the length between the coupling arms of the electrically insulating coupling members. If different ones are employed, there is an advantage that the lines can be used as they are even on tracks having different rail intervals.

  In addition, the height-adjustable sleeper of the present invention can be expected to have a particularly large effect of improving the efficiency of track maintenance when it is used on a curved line with a high frequency of cant adjustment. However, it is said that the frequency of track maintenance work is only low for a straight track, and it is extremely easy to fine-tune the height of the rail surface. The same efficiency improvement effect can be expected.

The height-adjustable sleeper of the present invention will be described below with reference to the drawings, but the present invention is not limited by the description of the drawings.
FIG. 1 is an external perspective view in which a part of an example of a height-adjustable sleeper of the present invention is cut out, and FIG. 2 is a longitudinal sectional view in the vertical direction. From these figures, the height of the present invention is shown. The adjustable sleeper T is provided with a coupling member 5 as shown in FIG. 6 at the center, and a structure in which a preliminary assembly P having the same structure as shown in FIG. Therefore, it can be seen that it has a completely symmetrical structure when viewed from the center.

  In these drawings, reference numeral 1 denotes a lower member formed in a horizontally long box shape. A pair of side walls 12 and 12 are erected on the left and right ends of the bottom plate 11, and the base end 13 has a width. It is reduced and opened in a bowl shape so that it can be fitted to the coupling arm 51 of the coupling member 5. A bearing wall 14 through which the elevating operation rod can pass is erected at the tip of the bottom plate 11 so as to be continuous with the side walls 12, 12. A bearing window is located near the upper edge of the substantially center of the bearing wall 14. A free bearing 15 which is formed and can be rotatably supported by inserting a lifting operation rod 2 described later is provided. Further, in the middle of the upper surface of the bottom plate 11, a thrust bearing 16 for lifting operation that can rotatably support the tip of the lifting operation rod 2 is provided.

  The lifting / lowering operation rod 2 has a male threaded portion 21 formed in the middle circumferential surface thereof, and is inserted through the free bearing 15 so that the tip thereof is rotatably supported by the thrust bearing 16. The base plate 11 is attached from the distal end side toward the proximal direction, and can be freely rotated by an appropriate driving tool such as a ratchet type torque wrench that can be fitted to the driving head 22 formed at the proximal end. Can be done.

  Reference numeral 3 denotes an elevating wedge that moves in conjunction with the elevating operation rod 2. As described in FIGS. 3 and 4, a base wall 31 is provided at the base of the elevating wedge 3 close to the free bearing 15. An internally threaded body 33 that is erected and rotatably engaged with the externally threaded portion 21 of the elevating operation rod 2 can slide only in the longitudinal direction in the vertically elongated hole 32 that is erected and provided substantially at the center of the base wall 31. It is fitted so that it cannot rotate. Then, a pair of right and left wedge plates 34, 34 stand in parallel so as to line up on the left and right sides of the lifting operation rod 2 from the left and right side ends of the base wall 31 of the lifting wedge 3 toward the base end direction of the bottom plate 11. It is installed. At the lower ends of the wedge plates 34, 34, leg plates 35, 35 are provided in parallel with the bottom plate 11, and swinging convex portions 36, 36 for reducing friction with the bottom plate 11 are formed. At the upper ends of the wedge plates 34, 34, sliding plates 37, 37 that are inclined so as to gradually decrease in height toward the base end of the bottom plate 11 are provided in a posture perpendicular to the wedge plates 34, 34.

  Therefore, the lifting wedge 3 having the above-described structure is placed on the bottom plate 11 so that the base wall 31 faces the inside of the bearing wall 14 of the lower member 1, and as shown in FIG. The tip of the elevating operation rod 2 is inserted into a free bearing 15 provided in the window, and then the male screw portion 21 of the elevating operation rod 2 is screwed into the female screw body 33 of the elevating wedge 3 and further advanced to advance the elevating operation rod. After the tip of 2 is fitted to the thrust bearing 16, it is supported so that the tip of the lifting operation rod 2 is not detached from the thrust bearing 16. Since the lift wedge 3 assembled in this way has a space between the pair of wedge plates 34, 34 that does not contact the lift operation rod 2 and the thrust bearing 16, the drive head of the lift operation rod 2 is formed. When a rotational force is applied to the female body 22, the female screw body 33 screwed into the lifting operation rod 2 cannot rotate but can swing up and down along the longitudinal hole 32, so that a force to move in the axial direction is generated. Then, no vertical force is applied to the lifting wedge 3, and the lifting wedge 3 can move forward or backward along the lifting operation rod 2 without any trouble.

  As described above, after assembling the elevating operation rod 2 and the elevating wedge 3 on the bottom plate 11 of the lower member 1, the upper member 4 can be covered. In the upper member 4, a pair of side walls 42, 42 are suspended from the left and right ends of the upper plate 41, and a shielding wall 44 provided with an elevating operation window 45 is provided at the tip of the upper plate 41. An openable / closable window lid 46 is provided on the outer surface of the shielding wall 44 so as to be continuous with 42 and cover the lifting operation window 45. The base end 43 of the upper plate 41 extends to a position where the width is reduced as in the case of the base end 13 of the lower member 1, but since there is no upper plate 41 beyond that, only the base end 13 of the bottom plate 11 is provided. However, in order to connect with the coupling member 5, it will be left open.

  A pair of left and right wedge wedge guide plates 47, 47 are provided in parallel with the side walls 42, 42 at positions corresponding to the wedge plates 34, 34 of the lift wedge 3 on the lower surface of the upper plate 41. The lower end of the upper plate 41 is inclined, for example, ascending sequentially from the proximal end to the distal end.

  When the preparatory assembly P assembled as described above opens the window lid 46 provided on the upper member 4, there is an elevation operation window 45 there, and the drive head 22 of the elevation operation rod 2 from the bearing window of the lower member 1. Can be seen protruding. Therefore, if a rotation operation is applied to the drive head 22, the female screw body 33 screwed to the lifting / lowering operation rod 2 is provided so as not to rotate with respect to the lifting / lowering wedge 3. In accordance with the rotation, the lifting wedge 3 moves forward or backward along the lifting operation rod 2 together with the female screw body 33. At this time, the swinging convex portions 36 and 36 formed at the bottom of the lifting wedge 3 reduce friction with the bottom plate 11, and the tilting sliding plates 37 and 37 are formed at the upper portion of the lifting wedge 3. Since it is provided, there is little friction between the lower and lower wedge guide plates 47 and 47, and even if a load such as a rail is applied to the upper member 4, the upper member 4 can be easily swung up and down. The height of the installation position of the rail, etc. can be changed.

It needs to be assembled. That is, the coupling member 5 includes, for example, a component including two coupling arms 52 and 52 projecting symmetrically from the left and right side surfaces of a main body 51 formed using, for example, an electrically insulating hard plastic material. The cover 53 covers a fitting portion between the base end 13 and the connecting arm 52 of the lower member 1, and the connecting bolt nut 54 connects the base end 13, the connecting arm 52, and the covering 53 integrally. Therefore, the distal end of the coupling arm 52 of the coupling member 5 is placed on and fitted to the base end 13 of the lower member 1 of the preparation assembly P, and then the cover 53 is fitted from above, and then two coupling bolts are fitted. The nut 54 is used to securely tighten the joint portion between the preparation assembly P and the joint member 5. And the height adjustment type sleeper T of this invention can be manufactured by couple | bonding the next preparatory assembly P with the coupling | bonding arm 52 which remains in the main body 51 of the coupling member 5 by the same procedure.

  As can be seen from FIG. 1 and FIG. 2 and the above description, the above-mentioned preparatory assembly P uses the coupling member 5 formed of an electrically insulating material, and the height-adjustable sleeper T of the present invention. Since it is a main intermediate product for assembly, the upper plate 41 to be assembled to the preparation assembly P in accordance with the situation of the installation point of the height-adjustable sleeper T of the present invention, the rail layout design image, etc. Form the shape suitable for laying the rail on it, or cushioning materials and binding materials necessary for laying the rail, or pretreatment materials necessary for mounting them. It is desirable to add preliminary processing such as attaching to the upper surface of the plate 41.
