Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a radiator moving device.

[Prior Art] Automobiles, especially buses, generally have a radiator mounted in the corner of the back of the bus. Until now, this radiator had been lowered directly below the floor of the bus when inspecting for problems.

[Problems to be solved by the invention] However, since the weight of this radiator reaches approximately 50 kg, attaching and detaching it is hard work that requires jacking, etc., and it also has the drawback that it is difficult to work because it is lowered directly below. Furthermore, there is a drawback that the fixing member cannot be attached to the space below the radiator mounting portion of the automobile.

[Means for solving the problem] The present invention was made in view of the above-mentioned drawbacks.
The purpose is to make it possible to move the radiator laterally with little effort, and to make it easy to install, remove, and inspect. The lower end of the lift lever is pivotally supported on the inner lower part, and the lift lever is rotatable in and out of the radiator inspection opening, and a spring urges the lift lever to rotate toward the inside of the vehicle. A protrusion is provided at the free end of the radiator frame, and a rail is provided at the top of the radiator frame that extends from near the inspection hole side end of the radiator frame to approximately the center of the radiator frame, and the inspection hole side end of the rail is opened and the center side The end of the rail is closed at a lower position than the inspection hole side end, and the appropriate section from the open end to the closed end of the rail is approximately aligned with the rotation locus of the protrusion, and when the radiator is mounted, the protrusion is connected to the lift lever. The present invention is characterized in that a stopper is provided which can be rotated to fit in and out of the rail from the open end of the rail and can lock the lift lever at the rail detachment position of the protrusion.

[Operation] When the locking state between the stopper and the lift lever is released, the lift lever is tilted by the biasing force of the spring, and the protruding portion is fitted into the rail. When the radiator is pulled out to the radiator inspection port side, the lift lever stands up, and the radiator is lifted by the lift lever standing up, and when the radiator is pulled out of the vehicle body, the radiator is lifted by the lift lever and the lift lever rotates. It is placed on the ground outside the vehicle.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, a radiator 2 is mounted on a corner of a back surface 1 of a bus, and an inspection port 4 is formed in a position of a bus body 3 facing the side surface of the radiator 2. The inspection port 4 is covered by an inspection port lid 5, and the inspection port lid 5 is rotatably supported at its upper end.

In FIGS. 2 and 3, a lift lever 7 is disposed on the bus body 6 near the inspection hole 4, and its upper end, that is, the free end 7a, is rotatable between the outside of the vehicle and the inside of the vehicle. , the lower end of the lift lever 7 is pivotally supported by a pin 8. A roller 9 is provided protruding from the free end 7a of the lever. A helical spring 10 applies a force to the lift lever 7, and this urging force acts on the lever 7 in a counterclockwise direction in the figure, that is, in a direction to move the lever into the vehicle. The stopper 1 of the lift lever 7 is attached to the bus body 6.
1 is attached, and this stopper 11 is perpendicular to the lever rotation plane between a position that prevents counterclockwise rotation of the lever and a position that allows counterclockwise rotation of the lever. It is configured to be movable in the direction of arrow A.

The radiator frame 2 is placed on the bus body 6,
A rail 12 into which the rollers 9 can be fitted is fixedly installed at a relatively upper portion of the radiator frame 2. This rail 12 extends from the vicinity of the end of the radiator frame 2 on the inspection hole side to the vicinity beyond the center O of the radiator frame 2 in the left-right direction, and the inspection hole side end 12A of the rail 12 is open and other Edge 1
2B is closed at a position lower than the inspection hole side end 12A. Moreover, the section 12C from the opening end 12A to the middle of the rail 12 is made substantially coincident with the rotation locus of the roller. Specifically, as shown in FIG. 4, this rail 12 is composed of a flat plate-like main body 12a fixed to the radiator frame 2 by welding or the like, and upper and lower extension parts 12b and 12c projecting almost vertically from the main body 12a. has been done. These upper and lower extensions 12b and 12c are parallel and spaced apart from each other by a distance somewhat larger than the diameter of the roller 9.

Next, the effect will be explained.

As shown in FIG. 2, when the radiator 2 is mounted on a vehicle, the stopper 11 holds the lift lever 7 in a substantially vertical position against the urging force of the spring 10 so that the roller 9 comes off the rail 12. It is locked. This stopper 11 is displaced, and the stopper 11
When the lift lever 7 is unlocked, the lift lever 7 is rotated counterclockwise by the biasing force of the spring 10, and the roller 9 is fitted into the rail 12 as shown in FIG. This rail 12 has an open end 12A
Since the section 12C from to the middle almost coincides with the rotation locus of the roller 9, the roller 9 further penetrates to the end of the section 12C due to the spring biasing force, and when the roller 9 penetrates to the end of the section 12C, The lift lever 7 is slightly tilted counterclockwise from the upright position. In this state, when the radiator frame 2 is pulled horizontally from the inspection port 4 in the direction of arrow B, that is, toward the outside of the vehicle, the rollers 9 move relatively within the rail 12 and reach the vicinity of the closed end 12B.

When the radiator frame 2 is further pulled in the direction of arrow B, the lift lever 7 rotates clockwise and the fifth
As shown in the figure, when the lift lever 7 is in the upright state, the radiator 2 is
to lift. At this time, the roller 9 is located at the rail closed end 12B, and this position substantially coincides with the left-right center O of the radiator 2, so the radiator 2 is maintained horizontally and lifted without tilting left or right. When the radiator 2 is further pulled, the lift lever 7 rotates further and is finally placed on the ground G as shown by the two-dot chain line in FIG. spring 10
The biasing force is the maximum torque generated on the lift lever 7 when the radiator 2 is placed on the ground G (the torque due to the weight of the radiator becomes larger as the lift lever is closer to the horizontal position, so in this embodiment, the above maximum torque is applied). The torque is determined to approximately match the torque produced when the radiator is mounted on the ground. Therefore, while the radiator 2 is lowered from the solid line position to the two-dot chain line position in FIG. Only a small amount of force is required to move it.

Inspection and repair of the radiator is performed with the radiator 2 placed on the ground in this way, but if the force of the spring 10 is acting on the radiator 2 by using the lift lever at this time, the radiator 2 is unstable and makes work difficult. Therefore, as shown in FIG. 5, the stopper 13 is attached to the bus body 6 to lock the lift lever 7 so that the force of the spring does not act on the radiator.

In addition, in order to make it possible to transport the radiator placed on the ground to another location, for example, as shown in FIG.
At this point, it is divided into two parts, and the rail end portion 12B is made removable. As a result, when the radiator is moved to the right after the rail closing end 12B is removed in FIG. 5, the rollers 9 are separated from the rails 12. This allows the radiator to be transported elsewhere.

In order to mount the radiator 2 on the ground into a car, the procedure described above can be reversed.

Next, the function of the stopper 11 will be explained.

When a radiator is attached to a bus, it is generally fixed to the bus body via a rubber mount, so vibrations of the automobile are transmitted differently to the radiator 2 and the lift lever 7. Therefore, even when the radiator is attached to the bus, if the rollers 9 are fitted into the rails 12, vibrational impact will be transmitted from the rollers 9 to the rails 12. Therefore, the stopper 11 locks the lift lever 7 and allows the roller to separate from the rail 12 when the radiator is attached to the bus.

Note that a protrusion such as a pin may be provided on the lift lever instead of the roller.

[Effects of the invention] As is clear from the above explanation, according to the invention, the radiator is lifted and moved between the interior and exterior of the vehicle by a lift lever that is rotatably supported. The radiator can be easily moved between the inside and the outside of the car without having to move, and the lift lever is equipped with a spring that biases it toward the inside of the car, and the force of this spring supports most of the weight of the radiator, greatly reducing the labor of the operator. can be reduced to Furthermore, there is also the advantage that it becomes possible to arrange fixing parts in the space below the mounted radiator.
