Description

  The present invention relates to a seam oiling device for oiling rail joints.

  In a railroad track, there is a rail joint that connects two rails adjacent in the longitudinal direction (see, for example, Patent Document 1). As shown in FIG. 6, the rail joint portion 10 is provided at an end portion of the rail 11 and includes a joint plate 12 and a joint plate fastening bolt 13. The joint plate 12 sandwiches the two rails 11 from both side surfaces. The joint plate fastening bolt 13 fastens the joint plate 12 to the rail 11. Between the end portions of the two rails 11, a gap 14 is provided to allow the rails to expand and contract due to temperature changes. In order to reduce the resistance when the rail expands and contracts, the rail joint portion 10 is oiled. Oiling of the rail joint 10 is performed twice a year in spring and autumn. It is not efficient to perform the oiling operation of the rail joint portion 10 manually.

  In order to improve the efficiency of oiling work at rail joints, there is known a rail fastening part oiling device in which an oil tank and an oiling nozzle are mounted on a self-propelled vehicle, and oil is injected into the rail joint from above. (For example, refer to Patent Document 2). The worker places the rail fastening part oiling device on the rail at the start of the oiling operation (mounting), and removes it from the track after the oiling operation. Since this rail fastening part oiling device is equipped with an engine for self-propelling in addition to an oil tank for oiling, etc., it becomes very heavy and is difficult to mount and remove. Moreover, this rail fastening part oiling apparatus has an oiling nozzle arranged at the front part of the self-propelled vehicle. For this reason, the oil sprayed from the oil nozzle is scattered in the form of a mist and applied to the worker on the self-propelled vehicle, so that the oil application work is not easy.

  In order to avoid the above-described problems, a seam oiling device that is connected to the rear of the track automatic bicycle has been created (not shown). This seam oiling device is equipped with an oil tank and an oiling nozzle on a frame having wheels, has no self-propelled function, and is pulled by an automatic track bicycle. An automatic track bicycle is a means for an operator to move on a track during track maintenance, and is self-propelled by an engine (see, for example, Patent Document 3). Such a towed seam oiling device does not have an engine or the like for self-running, and thus is lightweight. Moreover, since this joint oil coating apparatus injects oil behind a track automatic bicycle, the oil which is injected and scattered does not apply to the worker who rides on a track automatic bicycle.

  However, in order to use such a seam oiling device safely on the track, in addition to the supervisor and the operator who operates the automatic track bicycle facing forward as a worker riding on the automatic track bicycle, the seam facing backward is used. A total of three operators who operate the oiling device are required, and the oiling operation is not efficient. Also, as an automatic track bicycle, a two-seater is not sufficient, and one that can be used by three people is necessary. Furthermore, since the rail joint enters the field of view from the back for the operator facing backward, the visibility in the oiling operation is not good.

  Each structure of the joint oil coating apparatus 1 is further explained in full detail. The seam oiling device 1 has a frame 8 as a structural member (see FIG. 3). In the present embodiment, the frame 8 is made of aluminum for weight reduction. A pair of left and right wheels 2 are rotatably provided at the front lower portion of the frame 8. The frame 8 has a connecting portion 81 that protrudes to the rear in order to connect to the automatic bicycle. In addition to the oil tank 3 and the control unit 6, a compressor 82, an air tank 83, a headlamp 84, and a generator 85 are mounted on the frame 8. An oiling unit 9 having a nozzle 4 is attached to the frame 8. The oiling unit 9 is provided in the vicinity of the left and right lower portions of the joint oiling device 1 corresponding to the left and right rails (see FIG. 2).

  The oil tank 3 is a container that stores oil to be applied to the rail joint, and supplies oil to the nozzle 4. 1 to 4, the piping connecting the oil tank 3 and the nozzle 4 is not shown.

  The seam oiling device 1 has four nozzles 4 (2 × 2 = 4) corresponding to the seam plates attached to both side surfaces of the pair of left and right rails. As shown in FIG. 5, the tip of each nozzle 4 is directed toward the boundary between the rail 11 and the joint plate 12 in the rail joint portion 10, and injects oil obliquely downward. For the nozzle 4, a type that sprays the oil straight without spraying it is used in order to inject the oil without diffusing. In this embodiment, the nozzle 4 is a spray gun, and the spray pattern is pinpoint extrusion coating (model number SPV-ST-6PR, manufactured by Unicontrols Corporation). A needle nozzle may be used as the nozzle 4.

  The seam detection unit 5 is obtained by attaching a rod-shaped member 51 to the lever of the limit switch 52 (see FIG. 4). The rod-shaped member 51 normally protrudes downward, and when it comes into contact with a part of the rail joint, the tip end side moves rearward and the limit switch 52 operates. The output of the limit switch 52 is input to the control unit 6 (see FIG. 3).

  The controller 6 is also called an air unit, and is an electric circuit that controls the operation of the compressor 82 and the air supply for the operation of the nozzle 4. The control unit 6 has a timer. By adjusting the timer, the start and stop timings of oil ejection based on the detection of the rail joint by the joint detector 5 are adjusted.

  The compressor 82 creates compressed air. The compressed air is stored in the air tank 83. The compressed air stored in the air tank 83 is supplied to the nozzle 4 and the like via the control unit 6. The headlamp 84 is a lamp that illuminates the front. The generator 85 is an engine generator and supplies power to the control unit 6, the compressor 82, the headlamp 84, and the like.

  The oiling unit 9 has a movable plate 91 that is movable in the vertical and horizontal directions with respect to the frame 8. The support portion 7 is attached to the lower side of the movable plate 91 via a pressing spring 92. The oiling unit 9 has an upper and lower cylinder 93 and a left and right cylinder 94. The movable plate 91 is moved up and down by the upper and lower cylinders 93. As the upper and lower cylinders 93 are moved down the movable plate 91, the rollers 71 press against the rail head. The movable plate 91 is moved left and right by the left and right cylinders 94. The left and right cylinders 94 press the guide wheels 72 against the side of the rail head. The upper and lower cylinders 93 and 94 operate with compressed air. The compressed air supplied to the upper and lower cylinders 93 and 94 is controlled by the control unit 6 based on the operation of the operator. The left-right direction is a lateral direction orthogonal to the rail, that is, a sleeper direction.

  The oiling operation of the rail joint portion using the joint oiling device 1 configured as described above will be described. First, an automatic bicycle is placed on the rail. Next, the seam oiling device 1 from which the generator 85 has been removed is placed on the rail, and the generator 85 is mounted on the seam oiling device 1. The seam oiling device 1 is connected in front of an automatic bicycle.

  A total of two people, a supervisor and an operator, ride on an orbital bicycle as workers. The operator looks forward and operates the seam oiling device 1 and the automatic track bicycle according to instructions from the supervisor. The upper and lower cylinders 93 and 94 are moved to press the roller 71 against the rail head and the guide wheel 72 against the side of the rail head. Thereby, the nozzle 4 is positioned in the up-down and left-right directions with respect to the rail. The operator runs the orbital bicycle at an almost constant speed. When the joint detection unit 5 detects the rail joint, the joint oil application device 1 automatically applies oil to the rail joint. Since the joint oiling device 1 moves in the rail direction and injects the oil without diffusing, the oiling range is linear in the rail direction.

  When the oiling operation of the rail joint portion in the predetermined section is completed, the joint oiling device 1 and the automatic track bicycle are removed from the track.

  As mentioned above, according to the seam oiling apparatus 1 which concerns on this embodiment, since the seam oiling apparatus 1 is pushed on a rail and moves, the seam oiling apparatus 1 will be located in front of an operator, and back Is not required, and the oiling operation of the rail joint is made more efficient, and the visibility in the oiling operation is improved. Even if the seam oiling device 1 is positioned in front of the worker, the oil is injected without being diffused, so that it does not reach the worker. Since the oil is injected without diffusing, the oil consumption is reduced. In addition, the seam oiling device 1 does not require an engine or the like for self-running, and is reduced in weight.

  Since the control unit 6 starts and stops the injection of oil from the nozzle 4 based on the detection of the rail joint part by the joint detection part 5, the burden on the worker is reduced and the oiling work of the rail joint part becomes efficient. Is done.

  Since the rod-shaped member 51 is in contact with part of the rail joint, the rail joint is detected, so that the rail joint is reliably detected by the joint detector 5.

  Since the support portion 7 that supports the nozzle 4 has a roller that rolls on the rail head and a guide wheel that contacts a side portion of the rail head, the nozzle 4 is in the vertical and horizontal directions with respect to the rail. The oil that is positioned and injected from the nozzle 4 can be made to hit the rail joint with high accuracy.

  In addition, this invention is not restricted to the structure of said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention. For example, instead of the rod-shaped member 51 and the limit switch 52, a proximity sensor that detects the rail joint portion in a non-contact manner may be used as the joint detection portion 5. Further, the means for propelling the seam oiling device 1 is not limited to the automatic track bicycle, and for example, the seam oiling device 1 may be propelled by an orbital bicycle that travels manually.
