Description

Side flap door mounting device of bus {DEVICE FOR MOUNTING A SIDE FLAP DOOR ON A BODY OF BUS}

The present invention relates to a side flap door mounting apparatus of a bus, and more particularly, to improve workability by assembling by moving the side flap door of the bus to the mounting position using a horizontal moving cylinder and a tilting cylinder, and the side panel and the flap A side flap door mounting apparatus for a bus capable of maintaining a constant gap and step between a door and each flap door.

Automobiles can be divided into various sizes according to their size, use, and fuel used. Among them, the vehicle is classified based on the number of people that can ride, including a small RV vehicle that can be accommodated by a small number of people, a one box car that can accommodate 7 to 15 people, and There are various types of buses that can accommodate 30 or more people, and large buses that can accommodate 40 or more people. In particular, buses are being upgraded with improved living standards, and many carriers tend to prefer high-quality large buses in terms of management.

On both sides of these buses, a number of flap doors can be opened and closed to store luggage carried by passengers or to load various equipment required for operation (e.g. snow chains or spare tires). . The number of side flap doors varies depending on the type of vehicle, and in the case of long-haul transportation, about 15 are usually installed.

In the related art, when the side flap door is mounted by a worker, the worker manually operates the heavy flap door, thereby reducing workability and gap or step between the flap doors. There is a problem that occurs.

The present invention for solving the above problems can improve the workability by transporting the flap door to the mounting position by using two air cylinders instead of handling the heavy object manually when the flap door is mounted. It is an object of the present invention to provide a side flap door mounting apparatus for a bus.

1 is a front view showing the configuration of a side flap door mounting apparatus according to the present invention, Figure 2 is a side view of the flap door mounting apparatus shown in FIG.

As shown in these figures, in the overall configuration of the flap door mounting apparatus according to the preferred embodiment of the present invention, a pedestal 10, a plurality of vertical frames disposed perpendicular to the pedestal 10, and the vertical A horizontal frame connecting the frame, a tilting plate 20 disposed on an upper end of the vertical frame, a conveying plate 26 mounted on the tilting plate 20 so as to be slidable, and the tilting plate 20. It consists of a tilting cylinder 30 for rotating at an angle of and a conveying cylinder 40 for conveying the conveying plate 26 within a predetermined length.

Here, a plurality of casters 14 and 16 are attached to the lower part of the pedestal 10. 1, the caster 14 on the left side is pivotally mounted to one side end 10a of the pedestal 10 by a pin 13, and has a fixed structure that is fixed so as not to move when in use. The caster 16 on the left side is rotatably mounted to one side end 10b of the pedestal 10 by the pin 15, and has a structure that can be used swingably and securely. The balance weight 12 is provided on the pedestal 10.

The vertical frames 2, 4 attached on the pedestal 10 consist of a lower frame 2 fixed vertically on the pedestal 10 and an upper frame 4 which is screwed to the lower frame 2. The support rod 6 is disposed on the upper frame 4. One end of the tilting plate 20 is rotatably mounted to the support rod 6 by a pin 8. In addition, the lower frame 2 and the upper frame 4 are each provided with screw portions 2a and 4a, and a height adjusting handle 90 is mounted to adjust the height according to the vehicle model.

A center column 86 is vertically attached to the center of the horizontal frame 80 that horizontally connects the vertical frames 2 and 4, and an extension bracket 82 extending to one side is attached to the center column 86. It is provided. In addition, the tilting cylinder 30 is rotatably attached to the pin 84 at one end of the extension bracket 82.

One end of the tilting plate 20 for rotating the flap door D while being rotated at a predetermined angle by the tilting cylinder 30 is coupled to the rod 32 of the tilting cylinder 30 by a pin 34. And the other end is rotatably coupled to the support rod 6 of the vertical frames 2 and 4 by a hinge 8. In addition, as shown in FIG. 2, the tilting plate 20 includes a stopper 50 for restraining the transfer of the bracket 44 coupling the rod 42 of the transfer cylinder 40 to the transfer cylinder 40. 52 is provided.

The transfer plate 26 is mounted on the tilting plate 20 so as to slide along the guide means. The guide means consists of a guide rail 22 installed on the tilting plate 20 and a guide track 24 attached to the lower portion of the conveying plate 26 and slid along the guide rail 22. have. Therefore, in accordance with the operation of the transfer cylinder 40, the transfer cylinder 40 moves between the two stoppers 50 and 52 through the sliding movement of the guide track 24 installed on the guide rail 22, and the flap door ( D) is transferred from loading position to mounting position.

The transfer cylinder 40 mounted on the tilting plate 20 transfers the transfer plate 26 in the longitudinal direction by the rod 42. The tip of the rod 42 is connected to the middle lower end of the transfer plate 26 by a bracket 44.

At each corner of the transfer plate 26, seating members 28, 46, and 48 to which the flap door D is mounted are provided. As shown in FIGS. 3A and 3B, the end portions of the flap doors D are seated on the upper surfaces 48a and 46a of the mounting members 48 and 46, respectively, to prevent the flap doors D from being damaged. It is made of urethane material.

In addition, one end of the transfer plate 26 is further provided with an extension arm 70 extending around the fixing pin 72 to prevent interference with the side panel P after the flap door D is mounted. . This extension arm 70 can be extended as shown by a phantom line in FIG. 4 so as to escape the regulating surface of the side panel P after mounting the flap door D, the end which meets the skid rail 74. 5, a urethane 76 for shock absorption is attached.

1, two stoppers 62 for regulating the tilting angle of the tilting plate 20 are provided near the support rods 6 on the vertical frames 2 and 4, and the T-shaped guide 54 is provided. 56 is further provided.

Next, a process of transferring the side flap door D from the loading position to the mounting position using the mounting apparatus of the present invention will be described with reference to FIGS. 1 and 2.

First, the flap door D is seated in a state where the seating member 46 on the transfer plate 26 is disposed at the position shown by the solid line in FIG. 2 when the flap door D is loaded. After loading the flap door D, a clamping operation is performed to prevent the door D from being separated. After the clamping is completed, the transfer plate 26 is restrained by the stopper 52 according to the operation of the transfer cylinder 40. Until the position shown by the virtual line in FIG.

After the transfer of the transfer plate 26 is completed, air is supplied to the tilting cylinder 30 to protrude the rod 32. The operation of the tilting cylinder 30 causes the rod 32 to protrude to lift the tilting plate 20, so that the tilting plate 20 is restrained by the stopper 62 about the hinge 8. While rotating, it is tilted to the mounting position as shown by the virtual line in FIG. At this time, the tilting cylinder 30 is supported by the pin 84 in the state rotated to the extension bracket 82 of the center column 86.

Next, the installation of the flap door (D) is carried out through the advancement of the mounting equipment and the guide matching process. After the flap door D is mounted, the mounting apparatus is reversed, and the tilting plate 20 is returned to its original position by the operation of the tilting cylinder 30, and at the same time, the transport plate 40 26 is conveyed until the bracket 44 is restrained by the stopper 50 to await loading of the next flap door D.

According to the present invention described above, workability is improved by accurately moving the assembly of the side flap door of the bus to the mounting position by using the horizontal moving cylinder and the tilting cylinder, and a constant gap and step between the side panel and the flap door and each flap door It can be maintained, there is an advantage that the scattering between each flap door does not occur.
