Description

  The present invention relates to a loading jig for loading an object having wheels on an automobile having a lifting platform for loading and unloading at the rear part of the loading platform, and an automobile provided with the loading jig.

  As a means for a maintenance worker to move on a railroad in a railway, there is an automatic track bicycle (for example, see Patent Document 1). A four-seater bicycle with two seats on the left and right and two rows on the front and rear is often used for the automatic bicycle. The automatic track bicycle is mounted on a car having a loading platform and is transported to the vicinity of the track. Since such an automatic bicycle is heavy, it is not easy for an operator to load the vehicle on a car bed. In addition, since the automatic bicycle has wheels, it needs to be fixed so that it does not move on the loading platform when it is transported by an automobile.

  2. Description of the Related Art An automobile having a lifting platform at the rear part of a loading platform and provided with a groove on the loading platform and the lifting platform is known (for example, see Patent Document 2). If such a car can be used to transport an automatic bicycle, the use of a lifting platform makes it easier to load the automatic bicycle into the loading platform. Since it is restrained, it is considered that it is easy to fix the automatic bicycle on the platform. However, an automatic bicycle with a long front and rear cannot use the elevator because the rear wheel does not rest on the elevator. Such a problem occurs not only in the case of an automatic track bicycle, but also when an elevator is used for loading a long object before and after having a wheel.

  A loading jig according to an embodiment of the present invention and an automobile provided with the loading jig will be described with reference to FIGS. As shown in FIG. 1, the automobile 1 has a lifting platform 2 for loading and unloading at the rear part of the loading platform 3. In FIG. 1, the backward direction is indicated by an arrow B (the same applies to FIGS. 4 to 6). As shown in FIGS. 2 to 6, the loading jig 4 is for loading an object 5 having wheels 51 (hereinafter also referred to as a loading object) onto the automobile 1. The loading jig 4 includes a loading platform rail 6 and a lifting platform rail 7 as rails on which wheels 51 are placed and guided in the front-rear direction. The loading platform rail 6 is provided on the loading platform 3 (see FIG. 4). The lifting platform rail 7 is detachably provided on the lifting platform 2 in correspondence with the loading platform rail 6. The elevator rail 7 extends rearward from the rear end 21 of the elevator 2 when it is provided on the elevator 2.

  As shown in FIG. 7, the lifting platform rail 7 has a flange 72 at the front end. The eaves portion 72 is for hooking the lifting platform rail 7 to the loading platform side end of the lifting platform 2.

  The elevator rail 7 has a protrusion 73 protruding upward at the rear end (see FIGS. 5 and 6).

  The lifting platform 2 of the automobile 1 has an engaging portion 22 (see FIG. 7). The engaging portion 22 engages with the elevator rail 7 to restrain the elevator rail 7 in the vehicle width direction.

  When the lifting platform 2 of the automobile 1 is at a predetermined height, the front end portion of the lifting platform rail 7 provided on the lifting platform 2 and the rear end portion of the loading platform rail 6 are opposed to each other. The wheel 51 can move between the carrier rail 6 (see FIG. 6).

  Each configuration will be further described in detail. The vehicle 1 is a vehicle that carries luggage or cargo, for example, a cargo vehicle (see FIG. 1). The lifting platform 2 of the automobile 1 is also called a tail lift, and is set up vertically when the automobile 1 is traveling, and is laid down when being loaded and unloaded, and is raised and lowered by power. When the lifting platform 2 is raised to a predetermined height, the lifting platform 2 and the loading platform 3 have substantially the same height. At this time, a gap for avoiding interference between the lifting platform 2 and the loading platform 3 exists between the lifting platform 2 and the loading platform 3.

  A pair of loading platform rails 6 and a pair of lifting platform rails 7 are used as the loading jig 4 (see FIGS. 2 and 3). The loading platform rail 6 and the lifting platform rail 7 are long members, the cross-sectional shape does not have to be the same as that of a railroad rail, has an appropriate strength, and must be demounted with wheels 51 mounted thereon. That's fine. In the present embodiment, the wheels 51 have flanges, and iron square pipes are used as the main material for the carrier rail 6 and the elevator rail 7. H-shaped steel or the like may be used as the main material.

  The loading platform rail 6 has a length that allows the wheels 51 of one or more loading objects 5 to be placed thereon and fits on the loading platform 3. In the present embodiment, the length of the loading platform rail 6 is set to be approximately the same as the longitudinal length of the loading platform 3 (see FIG. 4). The loading rail 6 has a wheel stopper 61 at the front end.

  The elevator rail 7 has a length that allows all the wheels 51 of one loading object 5 to be placed thereon, and is set longer than the longitudinal length of the elevator 2. Specifically, the lifting rail 7 has a length longer than the distance from the front end of the loading object 5 to the rear wheel 51, and the maximum length is limited by the load limitation of the lifting platform 2.

  The eaves portion 72 of the elevator rail 7 is formed, for example, by processing a metal plate into an L shape, and an L-shaped vertical portion is fixed to the front end portion of the elevator rail 7 by welding or the like (FIG. 7). reference). The thickness of the collar portion 72 is smaller than the gap between the lifting platform 2 and the loading platform 3.

  The convex portion 73 of the elevator platform rail 7 is formed, for example, by processing a metal plate or the like into a mountain shape, and is fixed to the upper side of the rear end portion of the elevator platform rail 7. The convex part 73 functions as a wheel stopper with respect to the wheel 51 of the loading object 5 (refer FIG.5 and FIG.6). The shape of the convex part 73 will not be limited if it functions as a wheel stopper.

  The lifting platform 2 has an inclined surface 23 that is inclined obliquely downward toward the rear in the vicinity of the rear end 21. In the present embodiment, the engaging portion 22 is a protrusion provided on the inclined surface 23. The elevator rail 7 is provided with a member 74 sandwiching the engaging portion 22 from the left and right sides. The engaging portion 22 is engaged by the elevator rail 7 and the member 74 to restrain the elevator rail 7 in the vehicle width direction (left-right direction).

  The engaging portion 22 is not limited to the above-described shape as long as the elevator rail 7 can be restrained in the vehicle width direction. For example, the member 74 may not be added to the elevator rail 7, and a pair of protrusions that contact the left and right side surfaces of the elevator rail 7 may be provided on the elevator 2 as the engaging portion 22. Further, as the engaging portion 22, a recess or a hole may be provided in the lifting platform 2, and a protrusion that fits into the recess or the like may be provided at the bottom of the lifting platform rail 7.

  A loading operation using the loading jig 4 configured as described above will be described. First, the lifting platform 2 of the automobile 1 is lowered, and the collar portion 72 of the lifting platform rail 7 is hooked on the loading platform side end of the lifting platform 2. The position of the collar portion 72 in the vehicle width direction is matched to the position in the vehicle width direction of the rear end of the loading platform rail 6 in a state where the lifting platform 2 is slightly lowered from the loading platform 3. In addition, you may provide the mark which shows the position of the vehicle width direction of the collar part 72 by the paint color etc. to the lifting platform 2 beforehand, In this case, after lowering the lifting platform 2 most (refer FIG. 1), the collar part 72 May be hooked on the end of the lifting platform 2 (see FIG. 5). The lift rail 7 is arranged so that the engaging portion 22 engages with the lift rail 7. The two lifting platform rails 7 are parallel on the lifting platform 2 (see FIG. 4). The position of each lifting platform rail 7 in the vehicle width direction is held at the front end portion of the eaves 72 by being hooked to the loading platform side end portion of the lifting platform 2 and held by the engaging portion 22 at the intermediate portion. The Therefore, the distance between the two elevator rails 7 is also maintained.

  The wheel 51 of the loading object 5 is placed on the elevator rail 7 with the elevator 2 lowered to the lowest position (see FIG. 5). A distributed load is applied to the lift 2 via the lift rail 7 and a moment is applied to the lift 2 via the flange 72 and the like. In the elevator rail 7, the portion protruding rearward from the rear end 21 of the elevator 2 is in a cantilevered state. Even when the wheel 51 rolls backward, such as when the elevator rail 7 is bent due to the bending moment due to the weight of the object 5 to be loaded, the wheel 51 hits the convex 73 and is rearward from the elevator rail 7. It is prevented that the wheel is removed.

  Next, the lifting platform 2 is raised to almost the same height as the loading platform 3 by power (see FIG. 6). The lifting platform rail 7 has substantially the same height as the loading platform rail 6. The loading object 5 is pushed toward the loading platform 3 and is moved from the lifting platform rail 7 onto the loading platform rail 6. The loading object 5 is fixed to the loading platform 3 by an appropriate method such as a rope. Since the loading object 5 is restrained in the vehicle width direction by the lifting platform rail 7, it is easy to fix it to the loading platform 3. In addition, when mounting two track automatic bicycles on the loading platform 3 as the loading object 5, a coupler included in the track automatic bicycle may be used for fixing the rear track automatic bicycle.

  Finally, the lifting rail 7 is removed from the lifting platform 2 and accommodated in the loading platform 3.

  The work of unloading the loading object 5 from the automobile 1 is performed in the reverse procedure of the loading work described above.

  As described above, by using the loading jig 4 according to the present embodiment for the automobile 1 having the lifting platform 2 for loading and unloading at the rear part of the loading platform 3, the lifting platform rail 7 is located behind the rear end 21 of the lifting platform 2. Therefore, the elevator rail 7 can be set to a length on which all the wheels 51 of the long object 5 are placed on the front and rear. Can be easily loaded onto the loading platform 3. Since the elevator rail 7 is detachable, it is not extended from the vehicle 1 by being removed except when the elevator 2 is used.

  Since the elevator rail 7 has a hook portion 72 for hooking on the loading platform side end of the elevator 2 at the front end, it is detachably provided on the elevator 2 and supported by the elevator 2.

  Since the elevator rail 7 has a convex portion 73 protruding upward at the rear end portion 71, even if the wheel 51 rolls backward on the elevator rail 7, the wheel 51 hits the convex portion 73 and moves up and down. It is prevented that the wheel is removed from the table rail 7 backward.

  The elevator 2 of the vehicle 1 is engaged with the elevator rail 7 and restrains the elevator rail 7 in the vehicle width direction, so that the position of the elevator rail 7 in the vehicle width direction is maintained.

  When the lifting platform 2 is at a predetermined height, the front end of the lifting platform rail 7 and the rear end of the loading platform rail 6 face each other, and the wheels can move between the lifting platform rail and the loading platform rail. Therefore, the object 5 raised using the lifting platform 2 can be easily loaded on the loading platform 3, and the article 5 mounted on the loading platform 3 can be easily lowered using the lifting platform 2.

  In addition, this invention is not restricted to the structure of said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention. For example, the loading object 5 having the wheels 51 is not limited to an automatic track bicycle, and may be, for example, a carriage for carrying luggage.
