Description

  The present invention relates to a vehicle transporter for transporting an automobile.

  2. Description of the Related Art Conventionally, in order to efficiently transport a plurality of automobiles, a vehicle transport vehicle in which transported vehicles are arranged and stacked not only in the front-rear direction but also in the vertical direction has been widely used.

  In order to arrange the transported vehicles in the vertical direction, the floor surface of the lower floor is preferably as low as possible. A trailer type vehicle carrier vehicle has no drive shaft and is convenient for lowering the floor, but it is difficult to lower the upper part of the coupler coupled to the tractor. On the other hand, if the transported vehicle is not loaded on the upper part of the coupler, the loading efficiency is lowered. Therefore, the upper part of the coupler is provided with a front floor that is higher than the lower floor, and the front floor is also covered. A transport vehicle is loaded (for example, refer to Patent Document 1).

  Also, in the case of a truck-type vehicle transport vehicle, a front floor having a floor surface higher than the lower floor is provided on the driver's seat of the truck, and the transported vehicle may be loaded.

  In order to load the transported vehicle on the front floor, which is higher than the lower floor, a road plate that rises forward and inclines between the vicinity of the rear end of the front floor and the floor of the lower floor. There is a need to. When the transported vehicle cannot be completely loaded on the front floor, the rear portion of the transported vehicle may be loaded and transported on the road plate.

  By the way, in recent years, for example, an automobile called a low-down vehicle, in which a front spoiler or the like is mounted and the ground height at the lower end of the vehicle is extremely low, is increasing. Such an automobile having a significantly lower ground clearance at the front lower end of the vehicle has a problem that the front lower end of the vehicle easily interferes with the road plate when riding on a road plate that rises forward and inclines.

  To avoid such interference and load a car with a significantly low ground height at the front lower end of the vehicle on the front floor, it is possible to configure a road plate for the transported vehicle to enter the front floor from the lower floor. There is a movable floor installed such that the front end portion can be raised and lowered between a rising position that substantially matches the height of the rear end portion of the front floor and a lowered position that substantially matches the height of the floor surface of the lower floor. Can be considered.

  When moving the transported vehicle from the lower floor to the front floor, first, the front end of the movable floor is held at the lowered position, and the operator operates the transported vehicle on the substantially horizontal movable floor. Loading. Next, the front end of the movable floor is raised to the raised position. As a result, even if the ground clearance at the front lower end of the transported vehicle is extremely low, the transported vehicle is loaded on a movable floor that rises forward and inclines so that the front lower end of the vehicle does not interfere with the road plate. Furthermore, the transported vehicle can get on the front floor by traveling on the movable floor.

  If a switch for raising and lowering the front end of the movable floor is installed at a position where it can be operated from the driver's seat of the transported vehicle loaded on the movable floor, the operator does not get off the transported vehicle. The movable floor can be raised from the lowered position to the raised position while riding on the transported vehicle, which contributes to improvement in work efficiency.

  By the way, when the transported vehicle gets into the front floor from the movable floor, it is preferable to securely hold the front end of the movable floor in the raised position, and hold the front end of the movable floor in the raised position with some holding mechanism. Can be considered. However, if the worker gets off the transported vehicle and performs the operation of operating the holding mechanism, the work efficiency is not substantially improved.

  On the other hand, a support part attached in the vicinity of the rear end part of the front floor, attached to the front end part of the movable floor, can be moved up and down together with the front end part, and can be locked to the support part. A movable locking portion that is movable between a protruding position that protrudes and a retreat position in which the elevation locus is separated from the support portion, a biasing portion that biases the movable locking portion in the direction of the protruding position, and a biasing portion It has a protruding position holding part for holding the movable locking part in the protruding position against the force, and when it is raised, the movable locking part retreats to the retreat position side while abutting on the supporting part, and below the supporting part. It is possible to move from the side to the upper side, and the movable locking part protrudes to the protruding position side above the support part and can be locked to the support part, so that the front end of the movable floor is automatically held at the raised position. It is conceivable to use an ascending position automatic holding mechanism configured as described above.

  When moving the transported vehicle from the lower floor to the front floor, first, the front end of the movable floor is raised from the lowered position to a height slightly higher than the raised position. Protrusively. Next, the front end portion of the movable floor is slightly lowered until the movable locking portion comes into contact with the support portion, so that the front end portion of the movable floor is automatically held at the raised position.

  As a result, the operator can perform a series of operations for moving the transported vehicle from the lower floor to the front floor while getting on the transported vehicle without getting off the transported vehicle, thereby improving work efficiency. be able to.

After that, the front end of the movable floor is lowered to the lowered position.

  In order to retract the movable locking portion to the retracted position, the operator must first get out of the transported vehicle and manually retract the movable locking portion to the retracted position side against the biasing force of the biasing portion. For this reason, even when the lift position automatic holding mechanism as described above is used, there is a problem that the work efficiency is low when the transported vehicle is moved from the front floor to the lower floor.

  In addition, vehicles transported with vehicles to be transported side by side in the vertical direction often have frames, hydraulic cylinders, etc. that constitute a loading platform on both sides of the movable floor in the vehicle width direction. In some cases, there is not enough space in the vehicle width direction between the door of the driver's seat of the transported vehicle and the vehicle transport vehicle, and it may be difficult for the operator to get out of the transported vehicle.
