Description

  The present invention relates to a cleaning system for cleaning the inside of a chassis frame of a vehicle. Note that the inside of the chassis frame refers to the inside of a recess that extends in the longitudinal direction in a U-shaped steel material that constitutes the chassis frame.

  The highways and main roads in snowy regions can be passed year-round by spraying an antifreezing agent or antifreezing liquid mainly composed of salt in winter. In addition, since an antifreezing liquid will become the same as an antifreezing agent when dried, the antifreezing agent and the antifreezing liquid are hereinafter collectively referred to as an antifreezing agent.

  The antifreezing agent is wound up while the work vehicle used for spraying is traveling and adheres to the entire chassis frame of the work vehicle being sprayed. On the other hand, even if it is a snow plow car or other work vehicle that does not spray anti-freezing agent, when driving on the road surface where anti-freezing agent is sprayed, the anti-freezing agent already sprayed on the road surface is hoisted The rolled antifreeze adheres to the entire chassis frame of the work vehicle. However, if the adhering antifreezing agent is left untreated, the chassis frame formed of a steel material will be corroded and the electrical wiring and brake piping installed inside the chassis frame will be deteriorated. Therefore, when the antifreezing agent is sprayed, the chassis frame of the vehicle used for the work needs to be cleaned.

  In addition, the special vehicle used for performing special work is not limited to anti-freezing spraying and is generally easily contaminated, and an apparatus for cleaning the special vehicle has been proposed. For example, in Japanese Utility Model Laid-Open No. 50-32869, a main water conduit is fixed to a chassis frame of a construction vehicle, and a branch pipe disposed from the main water conduit toward the wheel faces the outer peripheral surface of the wheel. There has been proposed a cleaning apparatus in which several nozzles are protruded. Japanese Laid-Open Patent Publication No. 54-31642 proposes a water washing apparatus equipped with a long fountain pipe having a large number of fountain ports provided above the body of an automobile.

  However, the conventional cleaning device is intended to clean sludge and the like attached to the vehicle body and tires, and cannot clean the inside of the chassis frame.

  In addition, when cleaning manually without using a cleaning device equipped on the vehicle, wiping high pressure water on the inside of the chassis frame without damage will damage the wiring and piping mounted on the inside of the chassis frame. There was a fear. Therefore, in order to prevent corrosion and deterioration of the chassis frame of special vehicles that spray anti-freezing agents, it has to be inserted between the frames and finely cleaned manually, which requires time and labor. there were.

  Therefore, the present invention is applied with a special vehicle and antifreeze agent for spraying the antifreeze agent without taking time and labor, and without damaging the wiring and piping mounted inside the chassis frame. Another object of the present invention is to provide a cleaning system that can clean the inside of a chassis frame of a special vehicle for traveling on a road surface.

  A cleaning system according to the present invention includes a bracket that is spanned between a pair of chassis frames that are parallel to the vehicle length direction, and a jet of liquid that is fixed to the bracket and that is ejected from an ejection port directed to the chassis frame. A nozzle that moves by a reaction force, a cleaning liquid supply pipe that communicates with the nozzle, and a cleaning liquid supply control unit that is connected to the cleaning liquid supply pipe and supplies the cleaning liquid to the nozzle.

  The cleaning liquid supply control means may supply the cleaning liquid continuously at a predetermined time interval for a predetermined time.

  The cleaning liquid supply control means may comprise heating means for the cleaning liquid and supply hot water as the cleaning liquid.

  Furthermore, the cleaning liquid supply control means may be a separate body from the vehicle provided with the frame, and may be freely contacted and separated from the cleaning liquid supply pipe.

  According to the cleaning system of the present invention, the nozzle disposed between the chassis frames moves due to the spray reaction force of the cleaning liquid supplied from the cleaning liquid supply control means, and the cleaning liquid is moved inside the chassis frame and its It can be spread evenly around the area. The movement of the nozzle is not limited, and may be appropriately moved according to the inner shape of the chassis frame. For example, it may be turned or reciprocated.

  In addition, by appropriately adjusting the spray pressure of the cleaning liquid sprayed from the nozzle nozzle, cleaning can be performed without damaging the wiring and piping installed inside the chassis frame.

  Therefore, according to the cleaning system of the present invention, there is no need for time and effort, and there is no need to spend time and effort on the special vehicle or the freezing agent for spraying the antifreezing agent without damaging the wiring and piping installed inside the chassis frame. It is possible to clean the inside of the chassis frame of a special vehicle for traveling on the road surface on which the prevention material is dispersed.

  Also, if the cleaning liquid is supplied continuously at a predetermined time interval for a predetermined time, the antifreezing agent gradually melts after contact with the cleaning liquid and the adhesion to the chassis frame decreases. In addition, the cleaning can be performed efficiently without manual adjustment work and monitoring work.

  Furthermore, if the cleaning liquid supply control means includes a heating means for the cleaning liquid and supplies hot water as the cleaning liquid, the time required for thawing the antifreezing agent can be reduced even in an environment where the temperature is low. Can be shortened.

  The cleaning liquid supply control means may be mounted on a vehicle body provided with a frame to be cleaned. However, if the cleaning liquid supply control means can be separated from the cleaning liquid supply pipe as a separate body from the vehicle body, it can be prevented from freezing. The space for installing equipment necessary for the agent spraying operation is not reduced, and it can be shared by a plurality of vehicles.
