Description

  The present invention relates to a rail mounting table used when temporarily placing a new rail for rail replacement of a track on the side of the track.

  When replacing a rail, there is a case where a new rail is temporarily placed on the side of the track (main line) in advance, but there has been no special provision for temporary placement so far, and generally used sleepers are placed every few meters. A new rail carried by a vehicle is lowered on this, and a dog nail is driven into a sleeper at an appropriate place on a curved road so that the rail does not move laterally, so that a temporarily placed state is maintained.

  When it is necessary to move in the vertical direction (longitudinal direction of the rail) from the temporary placement position during the replacement work, it is lifted using a Yamakoshi device, etc., and a roller for vertical movement is installed below it. Thus, the movement is assisted by the roller.

  In short, worn pillow wood used as a rail stand in the conventional example, especially when used on a curved road, must be driven by a dog nail to prevent falling off. However, it is not always easy to use because it requires installation work of dedicated rollers.

  The present invention was devised for the purpose of providing a dedicated rail stand that is convenient and unprecedented under such a normal situation.

  On the frame, a mounting table for receiving and supporting the rail on the upper edge, and a regulating material whose upper end protrudes from the upper edge of the mounting table is provided with the mounting table interposed between the regulating materials, A support shaft that is rotatably supported by a support material is horizontally provided on one of the front and rear sides of the mounting table, and a switching lever is provided on the end circumferential side of the support shaft. When lying down, the guide roller that pushes and supports the rail placed on the upper edge of the mounting table when the switch lever is raised is pivoted to the outside of the large-diameter shaft provided eccentric to the support shaft. Assembled and configured.

  According to the present invention, by arranging an appropriate number of items on the road bed and mounting the new rail on the mounting table, it functions as a rail mounting table, and there is no risk of dropping off due to the presence of the regulating material, and the rail It is possible to provide a rail mounting base that reliably secures a predetermined position.

  Also, when the switching lever is turned, the support shaft rotates, and the large-diameter shaft portion provided in the eccentric position of the support shaft pushes up the rail from the relationship of the eccentric position, and pushes it up above the rail stand to support it. When the rail is pushed in the longitudinal direction while maintaining the supported state, the rail can be moved with the help of the rotation of the guide rail, the rail can be moved in the vertical direction without requiring any special work, A rail stand that is easy to use can be provided.

  The rail pedestal A according to the present invention is arranged in an appropriate number at appropriate positions on the side of the road bed b, and is used for temporary placement by placing a new rail R to be exchanged with existing rails on the sleepers m of the road bed b. It is.

  In the figure, reference numeral 1 denotes a frame, and the frame 1 is composed of a horizontal rectangular upper piece 1a and front and rear pieces 1b and 1b 'which are provided on the front and rear sides of the upper piece 1a along the longitudinal direction. It consists of a metal frame.

  Reference numeral 2 is a handle piece that is erected on the opposite ends of the frame 1 by welding the lower part to the upper piece 1a of the frame 1 and the end surfaces of the front and rear pieces 1b, 1b '. It is configured so that it can be lifted and moved by using a handle portion configured by providing a through hole 2a.

  3 is a support member 3, 3 provided at the center of both sides of the upper piece 1 a of the underframe 1 on the handle part piece 2 side with bolts 4 and nuts 5. , 3 includes an end portion of a support shaft 7 which is supported by engaging the intermediate portion 7a with a recess in the upper end of the support piece 6 erected between the support members 3 and 3 of the upper piece 1a. 7b and 7b are rotatably supported.

  The support shaft 7 includes cylindrical large-diameter shaft portions 8 and 8 that are eccentrically provided between the end portions 7b and the intermediate portion 7a, and the large-diameter shaft portion 8 of the support shaft 7 is provided. The guide roller 9 is fitted on the outer side of the shaft so as to be rotatable (relative to the large-diameter shaft portion 8).

  Further, each end portion 7b of the support shaft 7 has a cylindrical body (the embodiment is a cylinder but may be a square tube) on the peripheral side portion between the support material 3 and the large-diameter shaft portion 8. A base tube 10a of the lever 10 is provided so that a rod-shaped lever member 10b can be assembled to the base tube 10a so as to be detachable. That is, the switching lever 10 is configured by inserting the tip of the lever member 10b into the base tube 10a and assembling (a rod-shaped body projecting in an arm shape on the peripheral side of the support shaft 7 is applied as the switching lever here. In the embodiment, the lever member 10b is assembled to the base tube 10a only when necessary, and the lever member 10b is removed from the base tube 10a when it is not needed for storage or transportation of the rail stand. The tip is inserted into the base tube 10a, the lever member 10b and the base tube 10a are assembled to each other to form the switching lever 10, and the lever 10 is When the support shaft 7 provided with the base tube 10 a is rotated around the support shaft 7, the guide roller 9 fitted outside the large-diameter shaft portion 8 provided eccentric to the support shaft 7 is within the range of the rotation angle of the support shaft 7. Will turn around.

  In the embodiment, a switching lever 10 is protruded from the support shaft 7 which is an eccentric shaft of the large-diameter shaft portion 8, and is in a lying state from the height position of the large-diameter shaft portion 8 when the switching lever 10 is in an upright state. Is set so that the height position of the large-diameter shaft portion 8 is higher. As described above, the guide roller 9 rotatably assembled to the large-diameter shaft portion 8 supports the roller 9. According to the eccentricity of the large-diameter shaft portion 8, the switching lever 10 is at a high position when it is in a standing state and at a low position when it is in a lying state so that the amount of upward protrusion from the support shaft 7 changes. It is.

  As a result, when the switching lever 10 is in the upright state, the rail R placed on the mounting table 11, which will be described later, keeps the temporarily placed state as it is, and when it is laid down, it is located above the mounting table 11. It protrudes and pushes up the rail R on the mounting table 11 and is positioned in the crossing direction with the rail R to receive and support the rail R.

  In this state, when the rail R on the guide roller 9 is pushed in the longitudinal direction, the guide roller 9 supporting the rail R is rotatably assembled to the large-diameter shaft portion 8 of the support shaft 7. The movement of the rail R is facilitated to assist the movement of the rail R in the longitudinal direction, and the movement of the rail is performed smoothly.

  The mounting table 11 is configured such that, when the rail R is temporarily placed, the rail R is received by the upper edge 11a and arranged on the support shaft 7 so as to stand on the upper piece 1a of the frame 1 at the rear. That is, the mounting table 11 is made of a rectangular metal plate, and has a lower end welded to the upper piece 1a and is erected side by side with the support shaft 7 on the upper piece 1a. The mounting portion of the rail R is used to receive and support the rail R on the upper edge 11a when the rail R is temporarily placed.

  On both sides of the mounting table 11, a regulating material (consisting of an elongated plate-like body but free in shape) standing by welding the mounting table 11 and the upper piece 1 a is provided, and the regulating material 12 has an upper end 12 a. Is in a position that always protrudes upward from the upper edge 11a of the mounting table 11 and the guide roller 9, and prevents the rail R on the mounting table 11 or the guide roller 9 from dropping off.

  Further, 12A is a central regulating member provided by welding to the mounting table 11 and the upper piece 1a at the intermediate portion of the mounting table 11, and in the case of the embodiment, a pair of large-diameter shaft portions 8 provided on the support shaft 7. Each rail R can be arranged (that is, two rails R can be arranged), and this central regulating member 12A is provided at the center in the left-right direction of the upper edge 11a of the mounting table 11 corresponding to this. Thus, the rail R is prevented from moving laterally and kept at a predetermined position.

  In the case of the embodiment, the two rails R are received and temporarily placed, but the number of the central regulating member 12A, the guide roller 9 or the large-diameter shaft portion 8 is increased to increase the number of the rails R. The rail R may be temporarily placed, or the center restricting member 12A and the like are omitted, and the guide roller 9 and the like are single, and the rail placing base for temporarily placing the single rail R is also applied to the present invention. Is applicable.

  In short, when the base cylinder 10a of the switching lever 10 is raised on the peripheral side of the end portion 7b of the support shaft 7, the guide roller 9 is moved downward from the upper edge 11a of the mounting table 11 (the mounting edge of the rail R). In the position, when the support state by the upper edge 11a of the rail R mounting table 11 is maintained, and when it is in the lying down state, the guide is rotatably assembled to the large-diameter shaft portion 8 provided eccentric to the support shaft 7. The roller 9 only has to protrude from the upper edge 11a of the mounting table 11 in accordance with the eccentric mode of the large-diameter shaft portion 8, push up the rail R, and receive and support it.

  Then, on the roadbed, the rail mounting bases A are arranged at appropriate intervals along the track, and the rail R is placed on the mounting base 11 (upper edge 11a) with the base cylinder 10a raised. The provisional state of the rail R can be obtained by receiving and supporting.

  When the rail R is lowered from the rail mounting base A, the lever 10b is inserted into the base cylinder 10a and the switching lever 10 is assembled and rotated. Then, the support shaft on which the base cylinder 10a of the lever 10 is projected. 7 rotates, and the large-diameter shaft portion 8 provided eccentric to the support shaft 7 also rotates. As a result, the guide roller 9 rotatably assembled to the large-diameter shaft portion 8 has a large-diameter shaft portion. 8 protrudes from the upper edge of the mounting table 11 within a preset range by the eccentric rotation of 8 and comes into contact with the rail R on the mounting table 11 to push it up. This pushed-up state is maintained by a so-called toggle mechanism. When the rail R is pushed or pulled in the longitudinal direction as necessary in this state, the load of the external force of the rail R is transmitted to the guide roller 9, and the guide roller 9 rotates. Thus, the movement along the trajectory direction is smoothly performed.

  In the embodiment, the point b on the outer circumference of the guide roller 9 that is farthest from the center of the support shaft 7 when the switching lever 10 is raised as shown in FIG. 3 is located behind the perpendicular line a passing through the center of the support shaft 7. However, when the switching lever 10 is tilted as shown in FIG. 6, the toggle mechanism is configured on the front side, but the point b need not be limited to the position of the embodiment.
