[Prior art]
2. Description of the Related Art Conventionally, in a vehicle (truck) that mainly loads bulk cargo directly on a carrier and transports the cargo, it is necessary to efficiently load and unload the cargo. For this reason, for example, trucks that load and transport earth and sand, etc., use a grab bucket etc. to improve the efficiency of loading work on the loading platform, and use a method that discharges by tilting the loading platform when unloading. Have been. In addition, when carrying bulk cargo (for example, chip material) having a small apparent specific gravity, a vehicle having a long carrier is used because the loading capacity is large. When handling such loose objects, it is structurally impossible to incline the cargo bed and discharge the cargo.Therefore, the vehicle is placed on a dedicated platform, and the entire vehicle is inclined and loaded on the cargo platform. Measures are taken to discharge the cargo from the rear end of the platform.
[0003]
By the way, as a means to improve the efficiency of unloading cargo from the truck bed, in addition to tilting the bed, a method of moving the partition plate from the cab side to the rear end on the bed and gradually unloading the cargo Has already been disclosed. For example, as known from Japanese Patent No. 3062568, a load receiving slide plate that can move back and forth from the cabin side to the rear end on the loading platform, and the side ends can be locked to the left and right loading platform side plates on the loading receiving slide plate. And a partition plate that moves only when the latch slide is engaged and moves together with the slide slide when unlocked, and moves the partition plate together with the advance of the slide slide to push out the load. A loading / unloading apparatus is described in which the load receiving slide plate is retracted after the partition plate is locked to correspond to the next forward operation, and the load is sequentially pushed to the rear of the loading platform and discharged by repeating this operation. ing.
[0004]
[Problems to be solved by the invention]
In a case where such a partition plate (push plate) is intermittently moved to extrude and discharge while sequentially receiving a load, the load receiving slide plate for the load must have a rigid structure. Must. To this end, sidewall structures are formed on both sides of the flat plate in order to make the cross-sectional structure rigid. Then, as a matter of course, the cargo enters into the gap generated between the platform side plate (body) and the side wall structure of the cargo receiving slide plate due to the forward / backward movement of the load receiving slide plate, and the frictional resistance increases, and the smooth movement is performed. The problem that it becomes difficult arises. Incidentally, it is apparent that it is structurally difficult to increase rigidity without forming a side wall structure on the load receiving slide plate. Therefore, measures to prevent cargo (foreign matter) from entering the slide portion are important for achieving the purpose.
[0005]
The present invention has been made in order to solve such a problem, and it is possible to prevent foreign matter from entering between a side wall structure portion provided on a load receiving slide plate and a load carrier side plate and making the load receiving slide plate inoperable. It is an object of the present invention to provide a movable space protection mechanism for a loading body and a load receiving slide plate of a transport vehicle, which can be prevented with a simple configuration.
[0006]
[Means for Solving the Problems and Functions / Effects]
In order to achieve the above-mentioned object, the movable body protection mechanism of the loading body and the receiving slide plate of the transport vehicle according to the present invention includes:
In a transport vehicle including a load receiving slide plate that reciprocates from the cabin side toward the rear end of the load platform at the load platform portion and a push plate that is subjected to locking / unlocking operation and unloading is performed thereon,
Sidewall structures of a required height are erected over the entire length on both sides in the width direction of the load receiving slide plate, and a gap between the side wall structures on both sides thereof and the inner side surface of the load carrier side plate is formed at least by the load receiving slide plate. The invention is characterized in that the base is covered by a protective cover fixed to the carrier side plate over substantially the entire length (first invention).
[0007]
According to the present invention, the load receiving slide plate is reciprocated from the cabin side toward the rear end portion of the load carrier in the load carrier portion, and the locking / unlocking operation is added thereon, and then, toward the rear end. In performing the operation of intermittently moving the push plate to be unloaded, the small gap formed between the inner side surface of the loading side plate and the side wall structure of the loading slide plate is protected by fixing the base to the loading side plate. By providing the cover so as to cover the entire length with the cover, the entry of the foreign matter into the gap portion is reliably prevented, and the load receiving slide plate can operate smoothly, and the effect that the slide mechanism is not hindered can be obtained.
[0008]
In the above invention, the side wall structure portions provided on both sides of the load receiving slide plate are formed in a box-shaped structure having a required width, and the upper portion thereof is formed on an inwardly downwardly sloped surface, and the protective cover is provided on the side wall structure portion. It is preferable to provide a configuration in which a slope corresponding to the inclined surface is provided so as to cover the upper side of the gap between the side wall structure portion and the inner side surface of the carrier side plate (second invention). In this way, the bulk load put into the cargo bed can be reliably prevented from entering the gap formed between the cargo carrier side plate and the side wall structure of the cargo receiving slide plate by the protective cover, and the amount of cargo is reduced. Also, there is an effect that foreign matter does not enter the gap portion because it flows down due to the inclined surface of the protective cover.
[0009]
Further, in the above invention, a recess having a size into which the side wall structure of the load receiving slide plate is formed is formed on the inner side of the load carrier side plate over substantially the entire length of the load carrier, and the side wall structure of the load receiving slide plate is accommodated in the recess. Preferably, the base end is fixed to a position above the upper end of the recess, and the protective cover is vertically suspended at least over the entire length of the load receiving slide plate (third invention). ). In this way, the load receiving space in the load receiving slide plate can be enlarged, and foreign substances can be prevented from entering the working gap, so that the unloading operation can be performed without disturbing the slide function.
