Description

  The present invention relates to a bogie and a vehicle body tightening device for recovery from derailment in a multipurpose toro such as a bogie used for rail transportation.

  When a multipurpose toro such as rail transport derails, the vehicle body (loading platform) is pushed up with a jack, and the carriage that is rotatably mounted on the vehicle body with a support shaft is rotated about the support shaft to obtain a predetermined on-track It is possible to recover by lowering the vehicle body so as to be arranged, but when the vehicle body is pushed up (when jacked up) during this recovery operation, the support shaft is provided with an extra length. Since the vehicle is connected to the vehicle by the required height, the vehicle must be lifted by more than the extra length to raise the vehicle from the road floor. I can't say that. Further, since the weight of the pin assembled to the shaft to prevent the carriage from being detached from the shaft is loaded by the rising of the cart, there is a risk of the pin being damaged.

  For this reason, conventionally, a cart and a vehicle body arranged on the cart using a manual hoist in which both ends of the wire are locked to hook materials provided on both sides along the longitudinal direction of the cart (sometimes loaded cargo is also together) The above-mentioned inefficiency and the risk of breakage of the pin are avoided by tightening.

  In short, the above-described conventional example is to tie the carriage and the vehicle body together with a wire rope, and to try to jack up the carriage and the vehicle body integrally, but to place the carriage on the track that is the restoration position. It is necessary to loosen the bound state and place the carriage in the normal position.As a result, there are the same problems as the conventional example, and to loosen the bound state, the load of the carriage is suddenly applied to the wire rope. As a result, there is a risk of breakage, and the work involves a risk.

  The present invention has been devised to provide an apparatus for safely and efficiently performing derailment recovery of a trolley (cart) by paying attention to the drawbacks of such a conventional example.

  In a multi-purpose toro such as a bogie that is assembled with a bogie and a vehicle body arranged on the bogie so as to be rotatable with respect to each other via a shaft, a retaining material provided at both front and rear end portions on opposite sides along the longitudinal direction of the bogie A tension holder provided on the vehicle body corresponding to each of the tension members and a hook for engaging one end of the tension holder with the tension member, and a wire rope for inserting and clamping the other end of the tension holder. To do.

  When the vehicle body is raised by the jack, the vehicle body rises with the trolley fastened by the wire rope. As a result, the trolley (the wheel) is separated from the road floor, and at this time, the load of the trolley is applied to the wire rope. The wire rope tries to follow the ascending direction, and the pushing force and pulling force according to the arrangement of each wire rope are loaded on the cart, and the cart can rotate around the axis and be automatically placed in the normal position. The descent work of the carriage onto the track can be performed safely, and the derailment recovery work can be performed smoothly.

  The drawings show an embodiment of a carriage and body tightening device for recovery from derailment in a multipurpose toro such as rail transportation according to the present invention, FIG. 1 is a schematic front view of a part of the multipurpose toro, and FIG. Fig. 3 is a side view of Fig. 1, Fig. 3 is a schematic plan view of a state where the vehicle body and the carriage are tightened, and Fig. 4 is a partial front view of the state where the vehicle body and the carriage are tightened.

  The bogie of the embodiment is a multi-purpose toro used for transporting rails to the site, etc., and a bogie (bogie bogie) 2 on each of the front and rear sides of a vehicle body (base frame) 1 having a sufficient length for mounting the rail. And a roller 3 (not shown) mounted on the vehicle body 1 side by the pair of carts (one of which is omitted in the drawing) is placed on the cart 2 so as to roll freely. The center part of the carriage 2 and the central part along the longitudinal direction (front-rear direction) of the vehicle body 1 are assembled to each other by the shaft 4, and the vehicle body 1 and the carriage 2 can freely rotate in the horizontal direction around the shaft 4. In such a state, the vehicle travels following the curved path even at the curved part of the track (rail).

  The carriage 2 (similarly shown in the drawings) is configured to run on a track having a pair of front and rear wheels 5 and 5, and as described above, the carriage 2 is arranged on both front and rear sides of the vehicle body 1. The multi-purpose toro (bogie car) is configured by supporting the vehicle body 1 so as to be rotatable about the shaft 4 with respect to the vehicle 1.

  Drawers 6 are provided at the four corners of the carriage 2, specifically, front and rear end portions on opposite sides along the front-rear (running) direction of the main body 2 </ b> A of the carriage 2, and are located almost directly above the drawable material 6. In this manner, the tension holder 7 is detachably attached to the side portion of the vehicle body 1 so as to correspond to each of the tension members 6.

  The drawing material 6 locks a hook 8a provided at one end of a wire rope 8 for fastening the vehicle body 1 and the carriage 2 to each other. In the embodiment, a shackle 6b (note that the shackle 6b is welded to the drawing substrate 6a welded to the vehicle body 1). The shackle 6b is configured to freely rotate about the lateral width), and the hook 8a is detachably locked to the shackle 6b so that one end of the wire rope 8 is retained. Although it is configured, it suffices that the hook 8a is locked to the carriage 2 side and the locked state is maintained, and it is not necessary to limit to the structure of the embodiment.

  The tension holder 7 is fixed by a clamping device that is inserted in one end of the holder main body 7A and protrudes from the other end of the wire rope 8 and is inserted in the main body 7A. A known device (for example, Japanese Patent Application Laid-Open Nos. 2004-123374 and 187718) that can release the pinched and fixed state of the intermediate portion of the wire rope 8 by operating a release lever 7B attached to the surface of the main body 7A. In the case of the embodiment, the mounting plate 9 is installed on the main body 7A of the tension holding bracket 7, and the through hole and the mounting plate 9 provided in the mounting portion 12 provided on the vehicle body 1 side are provided. The tension holder 7 is detachably attached to the vehicle body 1 so that the provided through holes are matched and the attachment pins 11 are attached to the through holes.

  The attachment / detachment means for the tension holder 7 with respect to the vehicle body 1 need not be limited to that of the structure of the embodiment, and even if the holder 7 is fixed to the vehicle body 1 from the beginning, there is no influence on the implementation of the present invention.

  Thus, at the time of derailment (wheel), the tension holding metal fittings 7 stored in the carriage 2 by appropriate means are provided on the vehicle body 1 in correspondence with the tension members 6 provided at the four corners of the carriage 2, respectively. 12, the mounting pin 11 is mounted as described above (although the hook 8a may be assembled to the drawing material 6 and mounted on the carriage 2 in the assembled state. FIGS. The rope 8 is housed in the housing part provided in the carriage 2 and the hook 8a led out from the housing part is attached to the retaining material), and is similarly stored in the carriage 2 (loaded) ) The tension in which one end of the wire rope 8 is attached to the carriage 2 side and the other end side is attached to the vehicle body 1 side so that the hook 8a of the wire rope 8 is locked (hooked) to the drawing material 6 on the carriage 2 side. The carriage 2 and the vehicle body are inserted into the holder 7. When a tension is applied between the tension member 6 and the tension holder 7 and the tensioned state is held by a clamping device installed in the tension holder 7, the carriage 2 is attached to the vehicle body 1 at the four corners by the wire rope 8. In a state where the carts 2 that are tightened and arranged before and after the vehicle body 1 are thus fastened to the vehicle body 1, when the vehicle body 1 is pushed up by the jack, the vehicle body 1 is accompanied by the cart 2 that is fastened by the wire rope 8 at four locations. As a result, the carriage 2 (the wheel) moves away from the roadbed, and the load of the carriage 2 is applied to the wire rope 8.

  Since there are wire ropes 8 that load the load at the four corners of the carriage 2, the wire rope 8 tends to follow the vertical direction due to the load of the carriage 2, and the force that tries to become the vertical direction is loaded on the carriage 2. Therefore, the carriage 2 rotates about the shaft 4 and returns to the normal position, the vehicle body 1 is lowered by the jack, the carriage 2 is arranged at the normal position on the rail, and the wire rope 8 is detached. By doing so, the recovery operation can be terminated.
