BACKGROUND OF THE INVENTION
The present invention relates to a cargo handling device for a truck bed.
[0002]
[Prior art]
The present inventor previously invented an unloading device for a truck bed that is simple and inexpensive, and that can be safely and efficiently performed by a small number of people. Patent No. 30625568 The patent was acquired as the issue.
[0003]
As shown in FIGS. 6 to 14, the content is made of a steel plate or the like on the bottom plate 14 of the loading platform 12 of the truck 11, and a slide plate 15 having the same width as the bottom plate 14 is placed on the back of the cabin 13. A cylinder 16 is disposed between the front end of the slide plate 15 as a mechanism for moving the slide plate 15 back and forth.
[0004]
Also, on the slide plate 15, the side edges can be locked to the left and right loading platform side plates 17 of the loading platform 12, and at the time of locking, the edges of the sliding plate 15 are cut off, and only the sliding plate 15 moves and is not engaged. At the time of stopping, a partition plate 18 that is coupled with the slide plate 15 by friction or the like and moves together with the slide plate 15 is provided.
[0005]
The partition plate 18 is preferably made of a steel plate or the like and has a base 18 a having a certain width so as to stand on the slide plate 15. Further, in the illustrated example, the engagement between the partition plate 18 and the loading platform side plate 17 is based on the stop pin 19.However, the present invention is not limited to this, and the mechanism of the loading platform side plate 17 is not limited to this. Any device that can be locked and released at any position in the length direction or at appropriate intervals may be used.
[0006]
As shown in FIG. 6, assuming that there is a load A on the loading platform 12 of the truck 11, the rear end is positioned where the bit 20 is located, and the rear end surface of the loading platform 12 is opened. Next, as shown in FIG. 7, when the cylinder 16 is extended, the slide plate 15 moves from the cabin 13 side toward the rear end, and the load A and the partition plate 18 on the slide plate 15 also move accordingly. In this state, the partition plate 18 is not locked to the loading platform side plate 17. As a result of the sliding of the slide plate 15, the rear end of the slide plate 15 protrudes on the bit 20 behind the loading platform 12 with the load A mounted thereon.
[0007]
Next, as shown in FIG. 8, the bulkhead plate 18 is locked to the loading platform side plate 17 with a retaining pin 19 or the like, the cylinder 16 is reduced, and the slide plate 15 is pulled to the cabin 13 side as it is. Since it is fixed by the partition plate 18, it does not move as it is, and the portion protruding on the bit 20 behind the loading platform 12 is removed from the slide plate 15, so it falls into the bit 20.
[0008]
If the load A is dropped in this way, the partition plate 18 is locked to the loading platform side plate 17 as shown in FIG. 9, the cylinder 16 is extended again, and the slide plate 15 is pushed out backward, and this (1 ) Repeat the procedure of pushing slide plate 15, (2) locking partition plate 18, (3) pulling slide plate 15, (4) dropping load A, (5) unlocking partition plate 18 Drop all load A into bit 20.
[0009]
FIG. 14 shows a state in which the entire load A is unloaded. In order to prepare for loading again, the partition plate 18 is moved to the front portion of the slide plate 15 and the cabin 13 side.
[0010]
The movement of the bulkhead plate 18 to the front is repeated by repeatedly engaging and releasing the load carrier side plate 17 so that the slide plate 15 is locked only when moving backward, or by moving the crane plate It is conceivable to use other means using other devices.
[0011]
[Problems to be solved by the invention]
In the truck loading platform unloading apparatus disclosed in Japanese Patent No. 30625568, the partition plate 18 is erected on the slide plate 15 by the base 18a. When the cylinder 16 is extended, the slide plate 15 moves from the cabin 13 side to the rear end. The load A and the partition plate 18 on the slide plate 15 should also move by that amount when moving toward the side, but the force is applied to the partition plate 18 in some form, and the slide plate 15 and the partition plate 18 are displaced. There was a fear.
[0012]
This shift may be due to a force that the load A tends to collapse. In addition, when the load falling into the bit 20 is piled up, the slide plate 15 moves so as to be inserted into the bit 20, but the partition plate 18 is disturbed by the piled load and may not move and may be displaced.
[0013]
The object of the present invention is to eliminate the disadvantages of the conventional example, the apparatus itself is simple and inexpensive, and can be used safely and efficiently with a small number of people. A floor plate that can move back and forth is placed on the bottom of the truck, and only the floor plate moves when locked on this floor plate. An object of the present invention is to provide a cargo handling device for a truck bed that can realize movement.
[0014]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention arranges a floor plate that can be moved back and forth on the bottom of the rack bed, and on this floor plate, it can be locked to the left and right side plates of the load bed, and only the floor plate moves when locked. In addition, in a cargo handling device for a truck bed provided with a pushing wall that moves together with the floor plate during movement, the pushing wall is erected on a support plate placed on the floor plate, and a spring as a pressing means is applied to the floor plate on the support plate. A strut rod that is interposed and pressed by the end portion is provided, and a reinforcing member such as a square tube is provided along the left and right ends of the floor board, and the end portion of the strut rod presses against the reinforcing member. The gist is that a rack portion is formed on the left and right loading platform side plates of the loading platform, and a cam that can be locked to the rack portion in only one direction and the locking direction to the rack can be reversed by the inclination of the pushing wall. It is what.
[0015]
According to the first aspect of the present invention, the load such as chips is placed on the floor plate and moves rearward together with the slide plate, and the rear load goes out from the truck bed. At this stage, the load is on the floor plate, but if the floor plate is pulled forward while locking the pushing wall to the loading plate side plate and restraining the front end of the load, the floor plate under the rear load disappears and falls.
[0016]
The lock between the push wall and the loading platform side plate is released, the load is moved backward together with the floor plate of the load, and the subsequent operation is repeated to drop the load sequentially from the rear. Even if the cylinder is used for the back and forth movement of the floor board, its stroke may be small and small, and the pushing wall does not push out the load such as chips, so its own strength and locking to the loading board side plate are also possible It doesn't have to be very robust.
[0017]
In addition, since the pushing wall is provided with a tension bar whose end is pressed against the floor board, sufficient frictional resistance can be obtained by this tension bar, and the load is reliably sent by moving the floor board and the pushing wall together. be able to.
[0018]
Further, when the pushing wall is locked to the loading platform side plate, only the floor plate under the load can be moved against the frictional resistance of the tension bar.
[0019]
In addition to the above action, the push wall is erected on a support plate as a base, and this support plate helps to secure a space for providing a tension bar, and it is also possible to provide a plurality of tension bars before and after. It becomes possible.
[0020]
Even if the floor board is a comparatively thin thing such as a steel plate and is lightly manufactured, it is possible to prevent deformation such as rolling up and distortion by arranging reinforcing members such as square tubes along the left and right ends. Further, the end of the tension bar is pressed against the reinforcing member, so that the pressing engagement with the floor board can be obtained with certainty.
[0021]
Further, since the tension rod is provided with a spring as a pressing means, it is possible to easily obtain a frictional resistance, and it is possible to easily and easily push back the pressure when resisting the frictional resistance.
[0022]
The left and right loading platform side plates of the loading platform can be locked to the pressing wall continuously and easily by a rack portion and a cam locked to the rack portion in only one direction.
[0023]
The cam can reverse the locking direction with respect to the rack by its inclination. In addition to moving the pushing wall and the load to the load discharge port as described above, the load can be discharged out of the container, and the cam and the rack rail are reversed. In order to move the pushing wall to the back of the loading platform, that is, to return the pushing wall moved to the load discharge port to the original position, the load and pushing on the floor plate are similarly performed as the first step. The wall is moved together with the floorboard, and then, as a second step, the rack rail and the cam are locked, the pushing wall is fixed, and only the floorboard moves in the direction of the load discharge port (outward direction). The pushing wall can be moved to the back of the loading platform by sequentially repeating the first stage and the second stage.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of a cargo handling device for a truck bed according to the present invention, FIG. 2 is a partially longitudinal front view of the same, and the same components as those in FIGS. It is attached.
[0025]
In the figure, reference numeral 12 denotes a truck bed, which transports scrap iron and other chips, granular materials such as gravel as a load A. The truck bed 12 is open at the rear end. In the present invention, the floor board 1 having the same width as the bottom board 14 is placed on the bottom board 14 which is the bottom of the loading board 12. The floor board 1 is made of a steel plate or the like, and although not shown, a cylinder (16 in FIG. 3) is disposed between the back of the cabin and the front end of the floor board 1 as a mechanism for moving the floor board 1 back and forth.
[0026]
Further, on the floor plate 1, the side edges can be locked to the left and right loading platform side plates 17 of the loading platform 12, and the edge of the floor plate 1 is cut when locked, and only the floor plate 1 moves, and when not locked, the floor plate is moved. 1 and a push wall 2 that moves together with the floor board 1 is provided.
[0027]
The push wall 2 was made of a steel plate or the like, and was erected on a support plate 3 as a base having a width so as to stand on the floor plate 1.
[0028]
Further, the floor board 1 is provided with reinforcing members 4 such as a square tube, a steel plate or a reinforcing bar along the left and right ends.
[0029]
The push wall 2 is provided with a tension bar 5 whose end is pressed against the floor plate 1 on the support plate 3, and the reinforcing member 4 such as a square tube whose end is disposed along the left and right ends of the floor plate 1. It was made to press against.
[0030]
Further, as shown in FIG. 3, in the present invention, the stopper pins 7 are provided at the upper ends of the left and right cargo bed side plates 17 of the cargo bed 12 of the truck 11 at appropriate intervals to form the rack portion 8. A cam 9 that is locked only in one direction on the eight stop pins 7 is provided.
[0031]
The cam 9 can be rotated by a shaft, and the inclination direction of the cam 9 can reverse the locking direction of the rack portion 8 with respect to the locking pin 7. That is, a claw that is locked in only one direction on the locking pin 7 of the rack portion 8 is provided at the end portion.
[0032]
Next, the usage will be described. As shown in FIG. 3, assuming that there is a load A on the loading platform 12 of the truck 11, the rear end is located where the bit 20 is located and the vehicle is stopped, and the rear end surface of the loading platform 12 is opened.
[0033]
The cam 9 engages with the stop pin 7 of the rack portion 8 to prevent the track 11 from moving to the cabin 13 side.
[0034]
If the cylinder 16 is extended, the floor board 1 moves from the cabin 13 side toward the rear end, and the load A and the pushing wall 2 of the floor board 1 also move accordingly. In this state, the relationship between the rack portion 8 and the cam 9 is such that the tip claw moves away from the continuous concave portion between the retaining pins 7 of the rack portion 8 and moves to the adjacent continuous concave portion along the rack portion 8 while sequentially shifting. Since it moves, the pushing wall 2 is not locked to the loading platform side plate 17.
[0035]
Further, since the pushing wall 2 is provided with a tension bar 5 whose end is pressed against the floor board 1, a sufficient frictional resistance can be obtained by the tension bar 5, and the floor board 1 and the pushing wall 2 are moved together. However, only the pushing wall 2 does not move and shift, and the load A can be reliably sent.
[0036]
As a result of the sliding of the floor board 1, the rear end of the floor board 1 protrudes on the bit 20 behind the loading platform 12 with the load A mounted thereon.
[0037]
Next, when the cylinder 16 is reduced and the floor plate 1 is pulled to the cabin 13 side as it is, the claw of the cam 9 is locked and fixed to the stop pin 7 of the rack portion 8, and the pushing wall 2 is fixed to the loading side plate 17. Since the front end of the load A is fixed to the pushing wall 2, the load A does not move as it is, and the portion protruding above the bit 20 behind the loading platform 12 is eliminated from the floor plate 1, so Fall to.
[0038]
In this way, when pulling only the floor plate 1 toward the cabin 13, the push wall 2 is locked to the loading platform side plate 17, so that it can be moved against the frictional resistance of the tension bar 5.
[0039]
If the load A is dropped, it is locked to the loading platform side plate 17, and the cylinder 16 is extended again to extrude the floor plate 1 backward. After that, (1) push out the floor plate 1, and (2) engage the push wall 2. Stop, (3) retract the floor board 1, (4) drop the load A, and (5) release the lock of the floor board 1 to drop all the loads A into the bit 20.
[0040]
In order to prepare for loading again from the state where all the loading A is unloaded, the push wall 2 is moved to the front part of the floor board 1 and the cabin 13 side.
[0041]
By the engagement of the rack portion 8 and the cam 9, only the movement of the cam 9 to the cabin 13 side (the front side of the loading platform 12) is allowed, and the backward movement of the loading platform 12 is prevented.
[0042]
When the cylinder 16 is extended, the floor plate 1 moves from the cabin 13 side toward the rear end, and the claw of the cam 9 is fixed by being locked to the stop pin 7 of the rack portion 8. It is locked to the side and only the floor board 1 is moved.
[0043]
Next, when the cylinder 16 is reduced and the floor plate 1 is pulled to the cabin 13 as it is, the relationship between the rack portion 8 and the cam 9 in this state is that the claw is detached from the stop pin 7 and moves to the adjacent continuous recess. Since it moves along the rack part 8 while being shifted sequentially, the pushing wall 2 is not locked to the side of the loading platform side plate 17, so that the pushing wall 2 on the floor plate 1 also moves accordingly.
[0044]
Thereafter, the procedure of (1) pushing out the floor board 1, (2) locking the pushing wall 2, (3) pulling in the floor board 1, and (4) releasing the locking of the floor board 1 is repeated to bring the pushing wall 2 to the front. Move.
[0045]
