Description

  The present invention relates to a work vehicle that cleans the rails and the periphery of the rails on the roadbed, and in particular, adheres in a grease shape by mixing dust, dust, or dust generated by wear into the lubricant applied to the subway rails. Scraping off the highly viscous deposits, exposing the side and tread on the rail head, washing the exposed rail, and sucking the dust that has fallen onto the roadbed between the rails It relates to a working vehicle.

  Recently, subways have been opened that use a linear motor as a drive source, and that function as rails and wheels to support the weight of the vehicle and to guide the direction of travel. In this linear motor drive system, a linear motor is arranged on the lower surface of the vehicle, a reaction plate is arranged between rails laid in parallel, and a propulsive force is obtained using the magnetic force between the two. is there.

  In the case of a linear motor drive system, no friction is required between the rail tread and the wheels, so smooth running is possible even on sharp curves and steep slopes, and motor noise is not generated, resulting in low noise. I can do it. In particular, since the motor is flat, there is an advantage that the floor surface of the vehicle can be lowered and the tunnel diameter can be reduced to reduce the cross-sectional area.

  When a normal railway vehicle travels, a large friction is generated between the wheel and the tread surface of the rail. In particular, in a curve, the flange is worn by the friction generated when the wheel flange contacts the inner surface of the rail, and it is necessary to grind the flange as the wear progresses. For this reason, lubricating oil is applied to the inner surface of the rail to reduce the frictional resistance.

  As the lubricating oil applied to the inner surface of the rail, a liquid oil is generally used. The applied lubricating oil may adhere to the rail while maintaining the lubrication function, but dust and dust in the atmosphere or dust that has entered the roadbed enter this lubricating oil, increasing the viscosity. It may change to a grease shape and continue to adhere to the rail. Such deposits can lead to the problem of falling on the roadbed between the rails in an unmanaged state and contaminating the surroundings.

  In a wheel-driven vehicle that travels outside the underground part, a large frictional resistance acts between the rail tread and the wheel, so even if the lubricant applied to the inner surface of the rail adheres to the tread. It is possible to keep the tread surface smooth and clean. Moreover, the lubricating oil adhering to the inner surface of the rail is washed by rain or the like, and the inner surface can be kept clean. Furthermore, even if the lubricating oil that adheres to the inner side surface of the rail and falls into a grease shape falls, there is no significant hindrance to vehicle travel. For this reason, in a vehicle driven by a wheel drive vehicle other than the underground portion, contamination with lubricating oil is not a big problem.

  In a linear motor-driven subway vehicle, the sharp curve of the route increases, so the wear of the wheel is severe, and it is necessary to grind the wheel frequently. For this reason, the lubricating oil applied to the inner surface of the rail also increases, and dust, dust, dust generated by wear, etc. are mixed into the lubricating oil, resulting in deposits. In particular, when the deposit falls on the roadbed between the rails and is wound up by the wind pressure or the like as the vehicle travels and is placed on the reaction plate, there is a possibility that the driving of the vehicle may be obstructed.

  In addition, in a linear motor drive type vehicle, since there is no large friction between the rail tread and the wheel, even if the adhering material adhering to the inner surface goes around the tread, the adhering material is removed by the wheel. Therefore, the tread cannot be kept in a smooth and clean state. For this reason, the grease-like object by the lubricating oil apply | coated to both the tread surface and inner surface of a rail adheres.

  In the case of subways, it is impossible to expect the rails to be washed with rain. Therefore, there is a need to develop a device for removing deposits attached to the rails, a device for cleaning the rails, and a device for cleaning the roadbed. It is requested.

  An object of the present invention is to provide a work vehicle that can remove the adhering matter adhering to the inner side surface and the tread surface of the rail, clean it, and clean the roadbed.

  In order to solve the above-described problems, a work vehicle according to the present invention is a work vehicle that cleans a rail and a roadbed while moving along rails laid in parallel, and scrapes off deposits attached to the inner surface of the rail. An inner side scraping member to be taken, an inner side biasing member for biasing the inner side scraping member toward the inner side surface of the rail, a tread surface scraping member for scraping off deposits adhering to the tread surface of the rail, and the tread surface Tread surface biasing means for biasing the scraping member toward the tread surface side.

  In the above-mentioned work vehicle, water in which water or a powder substance soluble in water is mixed on the inner surface of the rail (hereinafter, mixed water in which water and soluble matter are mixed is collectively referred to as “washing water”). It is preferable to have an injection nozzle for injecting the liquid, and it is further preferable to have a suction nozzle disposed at a corresponding position between the rails laid in parallel.

  In the first work vehicle, the inner surface scraping member urged toward the inner surface of the rail by the inner surface urging member, and the tread surface scraping member urged toward the tread by the tread urging member; Thus, it is possible to scrape off the adhering matter adhering to the inner side surface and the tread surface of the rail while moving. For this reason, it can scrape off before a deposit falls, and it can prevent a fall of a deposit and can prevent a fallen deposit from mounting on a reaction plate. Therefore, the deposits do not hinder the operation of the linear motor drive type vehicle.

  Further, in the second work vehicle, after scraping off the adhering matter adhering to the inner surface and the tread surface of the rail, or independently, the cleaning water is sprayed from the spray nozzle toward the inner surface of the rail. Can be washed. Therefore, the work of scraping and removing the adhering matter adhering to the inner surface and the tread surface of the rail and the operation of cleaning the rail after removing the adhering matter or the operation of directly washing the rail to which the adhering matter is attached are performed. Or independently of each other and the rails can be kept clean.

  Further, in the third work vehicle, even if the adhered matter attached to the rail falls between the rails laid in parallel, the fallen adhered matter can be sucked by the suction nozzle. I can do it. Therefore, the work of scraping and removing the adhering matter adhering to the inner surface and the tread of the rail, the operation of cleaning the rail after removing the adhering matter, and the operation of sucking the adhering matter dropped between the rails are performed simultaneously. It can be done and the rails and roadbed can be kept clean.

  The work vehicle according to the present invention is to scrape the adhering matter adhering to the rail while moving along the rail so that the adhering matter does not fall from the rail and soil the roadbed. Furthermore, by spraying water or a mixed water (washing water) in which soluble objects are mixed from the spray nozzle toward the rail, the rail can be cleaned, and a fallen object that falls between the rails can be removed. It can be cleaned. In particular, the present invention is advantageous when a reaction plate provided between rails laid in parallel is kept in a clean state as in a linear motor drive system. This is advantageous when it is not expected to clean the rail.

  The work vehicle according to the present invention may be a self-propelled vehicle that travels with an installed engine, or may be a towed vehicle that moves by being pulled by the self-propelled vehicle. That is, in the present invention, it does not matter whether the work vehicle is a self-propelled system.

  Therefore, the work vehicle selectively holds the functional units of the inner side scraping member, the inner side biasing member, the tread surface scraping member, the treading biasing member, the injection nozzle, and the suction nozzle, which will be described later, and is connected to the injection nozzle. The washing water tank, the soluble powder substance tank and the injection pump, the suction pump connected to the suction nozzle, and the traveling carriage equipped with the dust collection tank are configured. The traveling carriage preferably has an optimum size according to the number of selected functional units.

  The inner surface scraping member that scrapes off the adhering matter adhering to the inner side surface of the rail scrapes off the adhering matter adhering to the inner side surface of the rail head in contact with the inner side surface of the head of the rail, that is, the inner side surface continuous with the tread surface. Is configured to take. For this reason, the inner surface scraping member is preferably configured as a member having a shape substantially equal to the cross-sectional shape from the inner surface of the rail to the tread surface by a material having high wear resistance. However, when the inner surface scraping member is moved in contact with the inner surface of the rail, it is not preferable to scrape the base material of the rail by the inner surface scraping member.

  The inner surface urging member that urges and contacts the inner surface scraping member to the inner surface of the rail is not particularly limited as long as it can exhibit the above function. As such an inner surface biasing member, it is possible to use a tension spring or a compression spring, and the inner surface scraping member is made to approach or separate from the inner surface of the rail to be retracted. It is also possible to use an air cylinder.

  For example, when the inner surface urging member is constituted by an air cylinder, the inner surface is supplied by supplying air having a pressure for generating a force necessary to move the inner surface scraping member with respect to the air cylinder. The scraping member is brought into contact with the inner surface of the rail, and then the inner surface is scraped by supplying air having a follow-up pressure capable of maintaining the contact state of the inner surface scraping member with the inner surface of the rail. The member can be biased. Thus, it is preferable to select an optimum mechanism for the inner surface biasing member in accordance with conditions such as the size of the space necessary for the inner surface scraping member to operate.

  The tread surface scraping member that scrapes off the adhering matter adhering to the tread surface of the rail is configured to come into contact with the tread surface that is the surface of the head of the rail and scrape off the adhering matter adhering to the tread surface. For this reason, the tread surface scraping member is configured as a member having a substantially planar shape that can sufficiently come into contact with the tread surface of the rail by a material having high wear resistance, like the inner side surface scraping member. It is preferable.

  The tread surface urging member that urges and contacts the tread surface scraping member to the tread surface of the rail is not particularly limited as long as it can exhibit the above function. As such a tread urging member, it is possible to use a tension spring or a compression spring, and the inner surface scraping member is made to approach or separate from the inner surface of the rail to be retracted. It is also possible to use a cylinder.

  In particular, each scraping member is preferably inclined in the direction of progress of scraping so that the scraped deposit can move to a certain site and fall to a predetermined holding part. In this way, by inclining each scraping member toward the traveling direction, it adheres to the inner surface and the tread surface of the rail, and the deposits scraped by each scraping member are in a certain direction. It can be moved or dropped. For this reason, it is preferable to provide the bucket for hold | maintaining the deposit | attachment which fell in the vicinity of each scraping member.

  Each of the scraping members and each biasing member may be provided on a traveling carriage that constitutes the work vehicle independently. However, a scraping frame is provided in which each scraping member, each biasing member, and the bucket are attached in a state where the relative position with respect to the head of the rail is set, and the scraping frame is driven by an air cylinder, for example, with respect to the rail. It is preferable to be configured to move in the vertical direction. In this way, by providing a scraping frame to which each scraping member and each biasing member are attached, the scraping frame is brought close to the rail in a section where the scraping operation is performed on the rail, and each scraping member is placed on a predetermined surface. It is possible to retreat each scraping member by separating the scraping frame from the rail in a section where the scraping frame is not brought into contact with the rail.

  By constructing as described above, it is possible to scrape off deposits adhering to the inner surface and the tread surface of the rail with each scraping member as the work vehicle moves, and to supply the scraped deposits to the bucket. It becomes. For this reason, by providing the suction nozzle in the bucket, the scraped deposits can be accommodated in the suction tank without dropping onto the roadbed. Therefore, the adhering material does not fall between the rails, and a clean state can be maintained.

  The spray nozzle is cleaned by spraying cleaning water having a high pressure on the inner surface of the rail, and the shape and spraying capability of the nozzle are not limited as long as it has this function. . In particular, by spraying high-pressure water on the rail, the deposits adhering to the rail are forcibly removed, and it is preferable that a high force can be applied to the deposits. For this reason, it is preferable that water can be sprayed alone or by mixing an object having solubility in water.

  In the present invention, the injection nozzle only needs to be able to inject cleaning water onto the inner surface of the rail, and does not ask whether or not the cleaning water can be injected to the tread surface. That is, as long as the range in which the cleaning water is sprayed includes the inner surface of the rail, it is possible to use the spray nozzle that can spray the cleaning water to the tread surface. Further, even when the cleaning water is sprayed onto the tread surface, this spray nozzle is also included in the present invention when the sprayed cleaning water wets the inner surface.

  As the cleaning water for cleaning the rail, water containing clean water or intermediate water can be used alone, or mixed water mixed with a powder substance soluble in water can be used. It is preferable to select and use as appropriate according to the condition. For example, when the rail after the deposits are scraped off by the scraping member is cleaned, the object can be achieved by simply spraying water as cleaning water. In addition, when a small amount of adhering material is attached to the rail from which the adhering material has been scraped, or when the initial amount of adhering rail is small, a water-soluble powder substance is mixed as cleaning water. By spraying the mixed water, it is possible to perform cleaning by causing the deposit to peel by applying a mechanical force due to the soluble powder substance.

  It is preferable that the soluble powder substance mixed with water can retain a solid component when mixed with water and sprayed onto the rail. In this way, by maintaining the state as a solid at the moment when it is sprayed on the rail, it is possible to peel off by applying a mechanical force to the adherent adhering to the rail. After that, it dissolves in water over time to form a solution, which can be discharged in the same manner as normal water.

  The material of the soluble powder substance is not particularly limited as long as it contains a solid component when mixed with water and can be dissolved over time and flow like water. As such a substance, for example, there is sodium bicarbonate, which can be preferably used as long as it is slightly less soluble than ordinary sodium bicarbonate.

  The injection nozzle is provided at a position facing the inner side surface of the rail and spaced from the inner side surface by a predetermined distance on an injection frame arranged at a predetermined position of the traveling carriage constituting the work vehicle. In particular, the injection nozzle is connected to a washing water tank, a soluble powder material tank and an injection pump through pipes and hoses, and intermittently or continuously at a required position as the work vehicle moves. It is preferable that the cleaning water or the cleaning water in which a soluble powder substance is mixed in water can be selectively jetted. For this reason, a valve whose opening and closing is controlled by an electrical signal is provided in the vicinity of the soluble powder substance tank, and a valve whose opening and closing is controlled by an electrical signal is also provided at a position close to the injection nozzle. It is preferable to configure so that the spraying and blocking of water as cleaning water and the spraying and blocking of mixed water of water and soluble powder material as cleaning water can be controlled by opening and closing.

  The specifications of the capacity of the washing water tank and soluble powder material tank, the flow rate and pressure in the injection pump are not particularly limited, and the most suitable one according to the conditions such as the target work length of the day. It is preferable to select.

  Further, it is preferable to provide a washing water receiving container below the injection nozzle and partially extending near the lower surface of the inner side surface of the rail, and a suction pump is connected to the washing water receiving container. Is preferred.

  As described above, the cleaning water receiving container connected to the suction pump is disposed below the injection nozzle, so that the cleaning water is sprayed on the inner side surface of the rail and the inner side surface is cleaned. Sometimes it is possible to receive this wash water in a wash water receptacle. The washed water received in the washing water receiving container can be sucked with a suction pump and retained in the suction tank.

  The suction nozzle sucks dust falling between the rails laid in parallel to clean the road bed, and any one having this function can be used. The suction nozzle is attached to a suction nozzle frame disposed at a predetermined position of the traveling carriage, and is provided so as to be separated from the road bed by a predetermined distance.

  The suction nozzle is connected to a suction pump consisting of a dust collection tank and a blower or fan via a pipe or a hose. The suction nozzle is intermittently or continuously driven in a required section and falls to the roadbed. It is possible to suck the collected garbage and collect it in the dust collection tank.

By operating the air cylinder 34, the swing levers 27b and 26c are swung to move the inner surface scraping member 28 and the tread surface scraping member 30. The inner surface 1b of the rail 1 is configured to be close to or separated from the inner surface 1b. Particularly, since the air cylinder 34 is connected to the swing lever 27b via the long hole 35a and the pin 35b, the stroke of the air cylinder 34 has a margin corresponding to the length of the long hole 35a. Even in the reduction limit, the swing lever 27b can swing by an angle corresponding to the length of the long hole 35a.

  An inner surface urging member 29 is provided between the bracket 27a and the swing lever 27b. The inner surface urging member 29 includes a tension spring 29a and a bolt 29b. The bolt 29b is screwed into the bracket 27a, and the tension spring 29a is interposed between the tip of the bolt 29b and the swing lever 27b.

By adjusting the screwing length of the bolt 32b with respect to the bracket 32c, it is possible to adjust the pressure contact force of the tread surface scraping member 30 with respect to the tread surface 1a.

  The tread surface scraping member 30 has a shape corresponding to the outer shape of the tread surface 1a so that the tread surface 1a can be scraped by contacting the tread surface 1a of the rail 1, and the attached material can be easily scraped off. Therefore, the thickness is reduced toward the tip and further inclined toward the scraping direction.

  The joint of the rail 1 is connected in the longitudinal direction by disposing a joint plate 40 on both sides of the rail 1 and fastening the joint plate with bolts. For this reason, there exists a possibility that the rocking lever 27b which comprises the scraping apparatus B may interfere with the joint board 40. FIG.

  In order to avoid the above problem, a guide 36 is formed at the lower end of the swing lever 27b. The guide 36 is inclined so that the distal end portion 36a in the traveling direction is further on the inner side than the position where the distal end portion 36a protrudes to the innermost side of the joint plate 40. It has a guide surface 36b that extends backward in the direction of travel. As the traveling carriage 2 travels, the inclined tip portion 36a comes into contact with the joint plate 40, and as the traveling carriage 2 further travels, the guide 36 is forced along the joint plate 40 to the inside of the rail 1. It is possible to avoid the joint plate 40 by moving to (see FIG. 7).

  When the traveling carriage 2 reaches the target work position, the lifting cylinder 26 is operated to lower the lifting frame 27 and the air cylinder 34 is operated to bring the swing lever 27b closer to the rail 1 so that the tread surface is scraped. The member 30 can be brought into contact with the tread surface 1a of the rail 1 and can be urged by the tread surface urging member 32. At the same time, the inner surface scraping member 28 is brought into contact with the inner surface 1b of the rail 1 and the side surface urging member 29. Can be energized.

  As described above, when the traveling carriage 2 travels at a predetermined work speed while the scraping members 28 and 30 are in contact with the tread surface 1a and the inner surface 1b of the rail 1 and are urged, the scraping members 28 are moved. , 30 scrapes off deposits adhering to the tread surface 1a and the inner family surface 1b of the rail 1 and drops them to the bucket 33. Therefore, by operating the suction nozzle 11 provided in the bucket 33, it is possible to suck the deposit that has fallen into the bucket 33 and collect it in the dust collection tank 7.

  When the travel of the traveling carriage 2 reaches the joint of the rail 1, the guide 36 comes into contact with the joint plate 40 and forcibly moves. With this movement, the inner surface scraping member 28 moves inside the rail 1. The seam plate 40 can be avoided by being separated from the side surface 1b.

  The cleaning device C is disposed substantially at the center of the traveling carriage 2, and includes an injection nozzle 14a that injects cleaning water toward the inner surface 1b of the rail 1, and an injection nozzle 14b that injects cleaning water toward the tread 1a. have.

The kimono can be blown away for cleaning, and the tread surface 1a and the inner side surface 1b of the rail 1 can be made beautiful.

  The spray nozzles 14a and 14b are covered with a cover 41, and are configured to prevent sprayed cleaning water from being scattered around. The suction nozzle 12 is disposed inside the space formed by the cover 41. By operating the suction nozzle 12, the cleaning water in the cover 41 can be sucked and collected in the dust collector 7. It is.

  In the cleaning device C configured as described above, the high-pressure cleaning device 5 is operated in accordance with the degree of dirt on the rail 1, and cleaning water obtained by mixing water alone with a soluble powder substance is supplied to the spray nozzle 14a. , 14b toward the inner surface 1b and the tread surface 1a of the rail 1, it is possible to peel off and drop the deposits adhering to these surfaces 1a and 1b by the energy of the sprayed washing water. . In particular, when washing water in which a soluble powder substance is mixed with water is sprayed, the solid component of the soluble powder substance collides with the deposit attached to the rail 1 and flows and falls, Along with this, the deposits can be peeled off and flowed and dropped.

  In this embodiment, in order to protect the position where the cover 41 is higher than the tread surface 1 a of the rail 1, the washing water sprayed from the injection nozzles 14 a and 14 b and washing the tread surface 1 a and the inner side surface 1 b of the rail 1 is the road bed 19. Will fall.

  The suction device D is sprayed onto the fallen object that has fallen on the roadbed 19 (particularly, the deposit that has fallen off from the bucket 33 even though it has been scraped off by the scraper B, and the tread surface 1a and the inner side surface 1b of the rail 1). The cleaning water after cleaning these surfaces is sucked and cleaned.

  The suction device D is disposed corresponding to the road bed 19 between the rail 1 and the reaction plate 17, and has two suction nozzles 13 connected to the suction pump 6 and the dust collection tank 7. .
