Description

  The present invention relates to a loading apparatus and a loading method for placing a heavy object on a loading platform of a vehicle, and more particularly to a loading apparatus and a loading method that are optimal for placing a heavy article such as a motorcycle on the loading platform of a truck such as a light truck.

  The motorcycle is pushed up to the platform of the light truck by using a step board. In this method, a step board is disposed on the ground from the platform of the light truck so as to have a downward slope. Push the motorcycle up on the stepping board and place it on the platform. This method uses only a walk board, so it is convenient for mounting light and small motorcycles. However, since a large motorcycle is extremely heavy, it is very difficult to push it up stably so that it does not fall on the walking board. If the motorcycle falls on the walking board, it not only greatly damages the motorcycle but also makes it extremely dangerous.

  This disadvantage can be eliminated using a crane. A crane hangs and loads heavy objects such as motorcycles, so it can work easily, but it cannot always load and unload all heavy objects in an ideal state. For example, a heavy article such as a motorcycle has a harmful effect such as deformation when a strong force acts locally when it is suspended. It is also difficult to hang stably. Further, since the crane needs power to drive it, it requires a mechanism such as a hydraulic motor, a hydraulic cylinder driven by this, and a tilting arm.

If you can use the power to move the vehicle back and forth, that is, use the power of the engine of the vehicle to load heavy objects on the loading platform, you can work easily without using a dedicated power unit like a crane. . As a method for realizing this, a truck trailer has been developed in which a vehicle is moved back and forth and a container is placed on a loading platform (see Patent Document 1).

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below exemplify a heavy-weight loading device and a loading method for embodying the technical idea of the present invention, and the present invention does not specify the loading device and the loading method below.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The loading device for placing a heavy article on the loading platform of the vehicle shown in FIG. 3 to FIG. 11 is connected to the rear portion of the loading platform 21 of the vehicle 20, and the step 1 installed on the ground from the loading platform 21 to the ground, And a heavy load table 2 that moves along.

  The step 1 is connected to the rear end of the loading platform 21 so as to be detachable. The detachable step 1 is connected to the loading platform 21 when used, removed from the loading platform 21 when not in use, and carried on the loading platform 21. Furthermore, this step 1 is connected to the rear end of the loading platform 21 so that it can tilt. The step 1 that can be tilted can reliably place the lower end on the ground even if the ground has irregularities. Further, the walking can be smoothly slid on the ground by providing traveling wheels (not shown) at the rear, or having the lower end of the lower surface inclined downwardly like a sled. The step 1 can be lengthened and loosened in a state of being connected to the loading platform 21. A step 1 with a gentle slope can smoothly lift the heavy load table 2. The total length of the step 1 is determined so that the gradient is 20 to 45 degrees, preferably 25 to 40 degrees, and more preferably 25 to 35 degrees in a state of being connected to the rear end of the loading platform 21. Since the loading platform of the vehicle varies depending on the vehicle type, the length of the step is determined so as to have the above-described gradient in a state where it is connected to the loading platform.

  The step 1 in the figure includes one metal rod 1 </ b> A connected to the center of the loading platform 21. This metal rod 1A connects reinforcing rods 1B on both sides to prevent the metal rod 1A from bending sideways. The two reinforcing rods 1B have their rear ends connected to the middle of the metal rod 1A. The tip is connected to the loading platform 21 so that the width becomes wider toward the tip. Since the step 1 of this structure can move the heavy load table 2 with one metal rod 1A, the structure can be simplified and the manufacturing cost can be reduced. However, although not shown, the step may be a structure in which two or more metal rods are arranged in parallel. In the process of arranging a plurality of metal rods in parallel, the lengths of the respective metal rods are the same, and adjacent metal rods are connected or the tips are connected to the loading platform without being connected. The step composed of a plurality of metal rods can stably move the heavy load platform in a horizontal posture.

  FIG. 6 shows a structure for connecting the step 1 to the loading platform 21. In this step 1, the tilting plate 7 is fixed to the front end, and the tilting plate 7 is connected to the fixed plate 8 fixed to the loading platform 21 via the rotating shaft 9. The rotating shaft 9 penetrates the fixed plate 8 and the tilting plate 7 of the loading platform 21 so as to rotate horizontally and laterally, and connects to the loading platform 21 so that the step 1 can tilt. The rotating shaft 9 is inserted into the fixed plate 8 and the tilting plate 7 so as to be detachable. In this structure, the step 1 can be removed from the loading platform 21 by pulling out the rotating shaft 9. In the step 1 in which the reinforcing rod 1B is fixed to both sides of the metal rod 1A, the metal rod 1A is connected to the loading platform 21 without connecting the metal rod 1A to the loading platform 21, and the metal rod 1A is connected to the loading platform 21. Can be linked in place. However, this step can also connect both the reinforcing rod and the metal rod to the loading platform. In the course of arranging two metal rods in parallel, the tips of both metal rods are connected to the loading platform. In the course of arranging three or more metal rods in parallel, all metal rods are connected to the carrier, or two metal rods are connected to the carrier, and metal rods that are not connected to the carrier are connected to the carrier. Connect to the metal rod.

  The step 1 shown in FIGS. 3 to 5 is provided with a backward stopper 6 at the rear end for preventing the moving part 3 of the heavy load table 2 from moving backward. In the illustrated heavy load table 2, the moving unit 3 is a wheel 3 </ b> A, so that the reverse stopper 6 is located behind the wheel 3 </ b> A so as to stop the reverse of the wheel 3 </ b> A and protrudes upward from the metal rod 1 </ b> A. . In the step 1 provided with the backward stopper 6 at the rear end, the moving unit 3 of the heavy load table 2 is disposed at a fixed position of the step 1 and the vehicle 20 is moved backward to move the moving unit 3 of the heavy load table 2. Can move along step 1.

  In step 1, when the vehicle 20 is moved toward the heavy load table 2, the moving unit 3 of the heavy load table 2 is moved along this. Step 1 in FIG. 9 is a metal rod made of a metal square pipe. The moving unit 3 of the heavy object mounting table 2 that moves along the steps 1 is provided with hooks 3B on both sides of the wheel 3A. The metal rod 1A of the step 1 is guided between the rods 3B, and the wheel 3A moves along the step 1 of the metal rod 1A. However, the present invention does not specify the structure for moving the moving part along the steps as the above mechanism. Although not shown in the drawing, the metal rod is a grooved steel opening upward, and the wheel can be moved into the groove to move the moving part along the steps.

  The heavy load table 2 fixes a heavy load such as a motorcycle on the upper surface and mounts it on the loading platform 21. The heavy load mounting table 2 shown in the figure has a heavy load mounting portion 11 inside a frame 10 that connects a metal vertical frame 10A and a horizontal frame 10B in a square shape. The heavy load table 2 shown in the figure is provided with a mounting portion 11 in the center in the longitudinal direction so as to be convenient for mounting a motorcycle. The mounting portion 11 fixes a horizontal plate 11B between two vertical rods 11A. However, the heavy load table can also be used to conveniently load various heavy items with the entire surface as a loading portion.

  The heavy load table 2 shown in the figure has a moving unit 3 that rolls along the steps 1 at the front. The heavy load table 2 is used to place the heavy load 30 on the loading platform 21 in the steps shown in FIGS. As shown in FIG. 17, the heavy load platform 2 used for placing the heavy load 30 on the loading platform 21 in the steps shown in FIGS. 18 to 21 moves to both the front portion and the rear portion of the heavy load platform 2. Part 3 is provided. The moving unit 3 is a wheel 3 </ b> A that rolls on the step 1. The heavy load table 2 in which the wheel 3 </ b> A is provided in the moving unit 3 can move the moving unit 3 smoothly along the step 1 by rotating the wheel 3 </ b> A. However, the moving part of the heavy load table does not necessarily have to be provided with wheels. This is because the heavy load table can be slid along the steps and moved along the steps. The moving part that slides the step is provided with a fluororesin or the like on the contact surface with the step to reduce the frictional resistance.

  7 and 8 is provided with wheels 3A at an intermediate portion located in the center from the moving portion 3 at the front portion. As shown in FIG. 12, the heavy load table 2 provided with the wheels 3 </ b> A in the intermediate portion rolls on the steps 1 while the wheels 3 </ b> A in the intermediate portion are disengaged from the steps 1. Therefore, it can move along the step 1 more smoothly.

  The moving unit 3 moves along the step 1. The heavy object mounting table 2 that moves the step 1 composed of one metal rod 1A is provided with the wheels 3A of the moving unit 3 at the left and right centers. That is, the wheel 3 </ b> A of the moving unit 3 is arranged at a portion where the step 1 is moved. Therefore, for example, a heavy load platform that moves along a step of connecting two metal rods in parallel to the loading platform is provided with a wheel at a position where each metal rod rolls.

  Further, the heavy load table 2 of FIGS. 7 and 8 is provided with a balance leg 4 in the middle. The balance legs 4 are connected to both sides of the heavy load table 2. The balance leg 4 raises and lowers the height supporting the heavy load table 2 to support the heavy load table 2 at a predetermined height. The balance leg 4 shown in the figure is connected to both sides of the heavy load platform 2, that is, both sides of the frame body 10 so as to be able to rotate via the connecting shaft 12. The balance leg 4 stands upright and supports the heavy load table 2 in the raised position, and falls to place the heavy load table 2 in the lowered position. In the illustrated balance leg 4, a horizontal leg 4B is fixed perpendicularly to the lower end of the vertical leg 4A. The upper end of the vertical leg 4 </ b> A is connected to the heavy load table 2 by a connecting shaft 12. The balance leg 4 is connected to the heavy load table 2 so that the upper end of the vertical leg 4A can be rotated. The balance leg 4 makes the horizontal leg 4B horizontal to the ground and the horizontal leg 4B makes the vertical leg 4A self-supporting. Therefore, the horizontal leg 4B has a longitudinal length that allows the vertical leg 4A to stand on its own. As shown in FIGS. 12 and 13, the balance leg 4 makes the horizontal leg 4 </ b> B horizontal to the ground and the vertical leg 4 </ b> A self-supporting in a vertical posture so that the heavy load platform 2 is in the raised position. Further, as shown by a chain line in FIG.

  The balance leg 4 is self-supported in the raised position by the horizontal leg 4B, but the balance leg is provided with a rotation stopper (not shown) between the heavy load platform and the balance leg is set up with this rotation stopper. It can hold | maintain and can support a heavy article mounting stand in a raise position. The balance leg releases the rotation stopper and tilts it so that the heavy load table is in the lowered position.

  The balance leg 4 is connected to substantially the center before and after the heavy load table 2. In this specification, “substantially in the center” means a position of 40 to 60% from the front end when the front and rear length of the heavy load platform is 100%. The heavy object mounting table 2 in which the balance leg 4 is connected to the substantially front and rear centers can substantially balance the heavy object in the front-rear direction in a state where the heavy object is placed thereon. The heavy load mounting table 2 on which a heavy load is mounted in a balanced manner can be tilted back and forth with a weak force. For this reason, as shown in FIG. 12, the front of the horizontal heavy load platform 2 can be lifted and easily tilted to the backward inclined posture that is a downward slope toward the rear, and as shown in FIG. 13, The heavy load table 2 in the backward inclined posture can be easily tilted to the forward inclined posture that is downwardly inclined toward the front. Further, as shown in FIG. It can be lifted and tilted easily in a horizontal position. In addition, the heavy load platform 2 having the balance leg 4 connected to the substantially center fixes the heavy load 30 so that the center of gravity of the heavy load 30 is located in front of the balance leg 4. Accordingly, as shown in FIG. 13, the heavy load table 2 can be tilted from the backward inclined posture to the forward inclined posture.

  The height at which the balance leg 4 supports the heavy load table 2 in the raised position, in other words, the height of the balance leg 4 is set so that the vehicle 20 is moved backward as shown in FIG. In a state where the moving unit 3 is placed on the loading platform 21, the balance leg 4 is erected, and the lower end thereof is set to a height at which the lower end comes into contact with or approaches the ground. The balance leg 4 at this height is about half the height of the loading platform 21. This is because the balance leg 4 is connected to substantially the center before and after the heavy load table 2. If the balance leg 4 is too high, as shown in FIG. 12, the balance leg 4 cannot be raised without lifting the heavy load table 2 while the front end is placed on the cargo bed 21. Since the heavy load 30 is placed on the heavy load platform 2, a large force is required to lift it. Therefore, the balance leg 4 has a length that can be raised without lifting the heavy load table 2. If the raising position of the balance leg 4 is too low, it will not be possible to smoothly move to the loading platform 21 with the heavy load table 2 in a horizontal posture in the state shown in FIG. This is because when the balance leg 4 is lowered, the rear leg 5 standing as shown by the arrow in FIG. 14 is lowered, and when the rear leg 5 is lowered, the heavy load table 2 cannot be leveled in FIG.

  Further, as shown in FIGS. 7 and 8, the heavy load table 2 has rear legs 5 connected to both sides of the rear part. The rear leg 5 raises and lowers the height supporting the heavy load table 2 to support the heavy load table 2 at a predetermined height. As shown in FIGS. 10 and 11, the rear leg 5 of the figure is connected to both sides of the heavy load platform 2, that is, both sides of the frame body 10 via the rotary connecting shaft 13. The rear leg 5 stands upright and supports the rear part of the heavy load table 2, and the heavy load table 2 shown in the figure supports the rear end of the heavy load table 2 in the raised position, and falls to lower the rear part of the heavy load table 2. Position.

  10 and 11 is provided with a tilting stopper 14 for fixing the rear leg 5 so as not to fall down in a posture in which the rear leg 5 is set perpendicular to the heavy load table 2. The tilt stopper 14 is in contact with the surface of the rear leg 5 and is inserted into a stopper piece 15 that prevents the rear leg 5 from rotating in one direction, and a stopper hole 5A in the rear leg 5, so that the rear leg 5 rotates in both directions. And a stopper pin 16 for stopping the operation.

  The stopper piece 15 protrudes outward from the frame body 10 of the heavy load platform 2 and is fixed at a position where the rear leg 5 in a vertical posture is prevented from further rotating. The rear leg 5 is rotated and stood in the direction indicated by the arrows in FIGS. 14 and 19, but at this time, the further rotation from a right angle is stopped by the stopper piece 15.

  The stopper pin 16 is inserted into a stopper hole 5 </ b> A provided in the rear leg 5 at a position away from the rotary connecting shaft 13 to prevent the rear leg 5 from rotating in both directions. That is, the rear leg 5 is stopped in a vertical posture with respect to the heavy load table 2 so as not to fall down. The stopper pin 16 is inserted so as to be able to enter and exit the guide tube 17 fixed to the lower surface of the frame body 10. The stopper pin 16 is provided with a flange 16A at the rear end. A tension spring 18 of a coil spring is provided between the flange 16A and the guide cylinder 17.

The loading apparatus shown in FIGS. 3 to 8 loads heavy objects on the loading platform of the vehicle as follows.
(1) As shown in FIG. 3, the vehicle 20 is disposed in front of the heavy load platform 2, and the front end of the step 1 is connected to the rear end of the loading platform 21 of the vehicle 20. The step 1 is connected to the loading platform 21 with a downward slope toward the ground. The step 1 is connected in parallel with the direction in which the vehicle 20 is moved backward. In order to connect the steps 1, the fixing plate 8 is fixed to the rear end of the loading platform 21. The fixed plate 8 is fixed directly to the loading platform 21 or is fixed to the loading platform via a base plate (not shown). In order to fix the fixed plate to the cargo bed via the base plate, the base plate that fixes the fixed plate is placed on the cargo bed, and the fixed plate is fixed to the cargo bed. The step 1 is connected to the loading platform 21 by inserting the rotating shaft 9 through the tilting plate 7 and the fixed plate 8 in a state where the tilting plate 7 fixed at the tip is laminated on the fixed plate 8.

(2) As shown in FIG. 3 to FIG. 5 and FIG. 12, the wheel 3 </ b> A that is the moving unit 3 at the front of the heavy load platform 2 is connected to the rear end of the step 1. The heavy load table 2 is placed in the vertical direction of the step 1. That is, when the vehicle 20 moves backward, the step 1 is placed on the ground so as to move in the vertical direction of the heavy load platform 2. At this time, the wheel 3 </ b> A of the moving unit 3 is placed in front of the reverse stopper 6 provided in the step 1. The wheel 3 </ b> A placed here is prevented from retreating by the retreat stopper 6. For this reason, the wheel 3A does not come off the step 1.

(3) As shown in FIG. 3 and FIG. 12, with the balance leg 4 and the rear leg 5 lowered to a position where the heavy load table 2 is supported, the heavy load 30 is placed on the heavy load table 2. Put it on. (Fixing process)
FIG. 12 shows a state in which a motorcycle is loaded on the heavy load table 2 as the heavy load 30. In this step, preferably, the heavy object 30 is fixed to the heavy object mounting table 2 so that the center of gravity of the heavy object 30 is positioned in front of the rotating shaft 9 of the balance leg 4. As shown in FIG. 13, when the vehicle 20 is moved forward, the heavy load platform 2 is smoothly tilted from the backward inclined posture to the forward inclined posture. However, it is also possible to fix the heavy object to the heavy object platform so that the center of gravity of the heavy object coincides with the rotation axis of the balance leg or is behind the rotation axis. However, in this case, as shown in FIG. 13, even if the vehicle is moved forward, the heavy load platform does not naturally tilt from the rearward tilt posture to the front tilt posture, so the rear end portion of the heavy load platform is lifted. Therefore, it is necessary to tilt to the forward tilt posture.
Furthermore, as shown by a chain line in FIGS. 7 and 8, the heavy load platform 2 on which the motorcycle is loaded as the heavy load 30 has a stand 19 for positioning and holding the motorcycle wheel on the upper surface of the tip of the mounting portion 11.
