Description

[Detailed description of the invention] [Industrial application field] This invention is a shutter device for a heavy goods transport vehicle that can load and transport heavy goods and large parts loaded on pallets by itself in the premises of steelworks, shipyards, etc. It is related to.

[Conventional technology]

In steel manufacturing and shipbuilding, transportation costs account for a large proportion of the manufacturing price, and reducing these costs has long been an important issue. Particularly in recent years, there has been an increasing need to quickly transport goods that occupy even greater weight and volume in order to rationalize manufacturing processes, but on the other hand, it is difficult to maintain the same size of on-site aisles and cargo handling yards as before. In some cases, the space became even narrower, which became a problem for the work.

Therefore, in order to quickly and easily handle and transport heavy objects even when using relatively narrow cargo handling areas or winding passageways, pallets are supported on the bottom as shown in Japanese Utility Model Application No. 59-105534. A gate-shaped frame that can be rotated, a driver's cab provided at the front and rear of the frame, running wheels that can be steered left and right by more than 90 degrees, and a hydraulic cylinder for lifting and lowering that allows the height of the frame to be changed in two ways. A heavy-duty transport vehicle equipped with these features has been developed.

This large goods transport vehicle lowers the gate-shaped frame using a lifting hydraulic cylinder, steers the running wheels 90 degrees from the front and back directions, and turns the large goods transport vehicle laterally. Insert the engagement part of the lifter provided on the frame, then raise the gate-shaped frame using the lifting hydraulic cylinder, carry the pallet at the engagement part, and move the large object by directing the running wheels in the front and back direction. Move the vehicle to the designated location, stop the large material carrier at the designated location, lower the gate-shaped frame using the lifting hydraulic cylinder to ground the pallet, turn the traveling wheels laterally, and stop the large material carrier. The pallets are unloaded at a predetermined location by moving the pallets horizontally, and the wheels are turned back and forth to return to the original location.

[Problem that the invention attempts to solve]

However, in the case of such large-product transport vehicles, the pallet carrier body is formed in a gate shape, so when the pallets are loaded, rainwater etc. may splash onto the loaded items on the pallets during rainy days, resulting in damage to the pallets. A retractable shutter that can be raised and lowered is provided on both sides of the carrier body.

However, when the shutter is raised to open both sides of the pallet carrier body in order to load and unload pallets, rainwater adhering to the outer surface of the pallets falls onto the pallet being loaded and unloaded. , the load will get wet.

Therefore, in consideration of the above points, the present invention automatically arranges a rain gutter along the bottom edge of the pallet when the pallet rises, to prevent rainwater from falling directly from the bottom edge of the shutter and from splashing onto the loaded items. The object of the present invention is to provide a shutter device for a heavy-duty transport vehicle.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the present invention is a large goods transport vehicle equipped with shutters on both sides of a gate-shaped pallet carrying vehicle body, which has a driver's cab with running wheels that can be steered left and right by more than 90 degrees in the lower part. In the pallet device, a shutter that closes both sides of the pallet carrying vehicle body is provided so as to be retractable into the ceiling frame portion of the pallet carrying vehicle body, and a rain gutter is provided along the lower end of the shutter when the shutter is fully opened on the pallet carrying vehicle body. is rotatably provided, and an engaging portion is provided at the lower inner side of the shutter to engage with the rain gutter and rotate the rain gutter.

[Effect]

With this configuration, when the shutter rises, the rain gutter is rotated and the rain gutter is placed at the lower end of the shutter, and when the shutter lowers, the rain gutter is retracted, and the rainwater that falls from the lower end of the raised shutter is It can be discharged through the rain gutter from near the front and rear of the pallet carrying vehicle body.

〔Example〕

An example illustrated in the drawings will be described below.

FIG. 1 is a side view of the large object carrier, and FIG. 2 is a front view thereof. Driver's cabs 3, 3 are installed in series at the front and rear of the driver's cabs, and a group of many running wheels 4 are installed under suspensions 5 at the bottom of the driver's cabs 3, 3 respectively so as to be able to turn left and right by more than 90 degrees. Each traveling wheel 4 is collectively steered by electronic control, and even the long heavy goods carrier 1 can be moved extremely freely.

The gate-shaped pallet carrying vehicle body 2 includes a ceiling frame portion 10, front and rear frame portions 11 connected to the front and rear of the ceiling frame portion 10,
11, the lower part is open, and the inside, that is, the bottom part is devoted to the storage space of the pallets.
The vehicle body has a so-called floorless type, and both sides of the vehicle body are closed by shutters 6 that can be rolled up into the ceiling frame section 10, as shown in the left half of FIG. As shown in the right half of FIG. 1, it is opened.

Further, main lifters 20, 2 are provided on the inner wall surfaces of the front and rear frame parts 11, 11 with engaging parts 21, 21 that engage with the pallet 40 and support the pallet 40.
0 are arranged to be movable up and down, respectively, and sub-lifters 3 are provided on both side walls of the front and rear frame parts 11, 11.
0 and 30 engaging claws 31 and 31 are rotatably provided, respectively, and the pallet 40 is supported by the main lifter 20 or the sub-lifter 30.
