Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a cargo transport vehicle, and more particularly to a transport vehicle whose cargo platform can be tilted freely.

[Prior Art] Conventionally, this type of transport vehicle is provided with a flat loading platform above an engine section, and cargo is placed on the loading platform for transportation. The carrier is horizontally fixed to the frame.

When loading and unloading cargo from a truck, it is either done manually or, in the case of heavy items, an inclined plate is erected from the ground on the truck and the cargo is loaded and unloaded while sliding on the inclined plate. .

[Problems to be Solved by the Invention] As described above, conventionally, when loading and unloading heavy cargo from a truck, an inclined plate is prepared separately from the transport vehicle.

Therefore, a technical problem arises that must be solved in order to be able to load and unload heavy cargo using a transport vehicle, and the present invention aims to solve this problem.

[Means for Solving the Problems] This invention was proposed to achieve the above object, and is directed to a transport vehicle equipped with a mechanical part such as an engine and a flat loading platform on the upper part of the engine part. It is an object of the present invention to provide a transport vehicle, characterized in that the loading platform is formed to be rotatable using one end of the loading platform as a fulcrum, and the loading platform is configured to be tilted and extendable so as to be able to approach the ground. It is something to do.

[Function] Since the transport vehicle of the present invention can tilt the loading platform, the inclined loading platform can be extended and brought close to the ground. The other end of the loading platform is flipped up to a high position, and by locking the other end of the loading platform to a truck, for example, an inclined loading platform is constructed from the truck to the ground.

Therefore, when loading and unloading heavy objects onto trucks,
Loading and unloading of cargo can be carried out extremely easily by sliding the cargo on the erected inclined cargo platform.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings. In FIGS. 1 to 3, 11 is a loading platform, 12 is a frame 15 provided at the bottom of the loading platform, and this frame 1
A bottom plate frame 13 is fixed to the lower surface of the bottom plate 2, and the left and right side edges 13a, 13a of the bottom plate frame 13 are bent upward to improve mechanical strength. An engine I4 is mounted on a bottom plate frame 13 at a central position within the frame 12, and the bottom plate frame! A transmission case 15 is mounted on one end of the bottom plate frame 13, and a generator 16 is mounted on the other end of the bottom plate frame 13, thereby forming an engine section I7. Since the lower part of the engine section 17 is covered by the bottom plate frame I3, it is protected from stones, mud, etc. on the ground even if the minimum ground clearance is small.

A two-stage pulley 19 is fitted to the output shaft 18 of the engine I4, and a V-belt 22 is stretched between the two-stage pulley 19 and the mission pulley 21 fitted to the input shaft 20 of the transmission case 15. A V-belt 25 is stretched between the power generation pulley 24 fitted on the rotating shaft 23 of the generator I6 and the two-stage pulley 19. Therefore, since the driving load of the engine] 4 is distributed evenly between the front and rear, the output shaft of the engine 1
8 is prevented from shifting to one side. The rotation of the engine 14 drives a generator 16, which is used as a power source for attached work tools such as a work light and an electric motor. On the other hand, the rotation of the engine 14 is also transmitted to the input shaft 20 of the transmission case 15, and rotates the left and right drive wheels 26, 26 via a reduction gear (not shown) in the transmission case 15. The driving wheels 26, 26 are pivotally connected to one end of the side surface of the frame 1.12, and a crawler 28.28 is wound between them and a driven wheel 27.27 pivotally connected to the other end of the side surface of the frame 12. . Note that 29 is a wheel provided between the driving wheel 26 and the driven wheel 27, and 3o is a retractable handle fixed to the other end of the frame 12.

Here, the loading platform 11 is separated into an upper loading platform 11a and a lower loading platform 11b. Ia is superimposed so that it can slide on the upper surface of the lower loading platform 11b using the guide bin 31 as a guide, as shown by the chain line in the figure.

Also, a bracket 32. is attached to one end of the lower surface of the lower loading platform 11b.
32 is provided vertically and is pivotally connected to a bracket 33.33 fixed to one end of the upper surface of the frame 12 by means of a pin 34.34. Further, the tip of a hydraulic cylinder 36 pivoted at approximately the center of the frame 12 is connected to a bracket 35 vertically installed near the center of the lower surface of the lower loading platform 11b.

Then, when the hydraulic cylinder 36 is extended, the loading platform IJ is moved to the pin 3 of the bracket 32, 32, as shown in FIG.
4.34 as a fulcrum, the other end of the loading platform 11 is flipped up and tilted. Next, the transport vehicle is moved to truck 37.
and lock the tip of the lower loading platform 11b to the truck 37. At that time, if the handle 30 comes into contact with the track 37, the handle 3o is tilted downward. Furthermore, the upper loading platform Jfa is extended while sliding, and one end thereof is brought close to and grounded on the ground, as shown by the chain line in the figure.

(In this way, a sloped loading platform II is constructed from the truck 37 to the ground, and if cargo is loaded and unloaded while sliding the loading platform 11, even heavy cargo can be easily loaded. For example, when carrying out excavation work in a narrow space, when unloading an ultra-small excavator from a truck or loading it into the trunk, the loading platform 11 of the transport vehicle may be tilted. An excavator drives slowly on the loading platform II to load or unload the cargo onto the truck.Therefore, there is no need to prepare a separate inclined plate for loading and unloading, and the M transport vehicle can be used to load and unload cargo. It can be used as an aid for unloading.

FIG. 3 shows a transport vehicle for scooping, and a loading platform 4 is installed in place of the loading platform 11 on the upper part of the frame I2 of the aforementioned transportation vehicle.
1 is included. The loading platform 41 has an open front end 42, and left and right side plates 43, 43 and a rear plate 44 are provided upright.

When the hydraulic cylinder 3G is extended as shown in FIG. 4, the loading platform 4I is tilted and the front end 42 comes into contact with the ground. If the transport vehicle is moved forward in such a state, dirt, dust, etc. on the ground can be scooped into the loading platform 41, and if the hydraulic cylinder 36 is contracted again to return the loading platform 41 to a horizontal position, the aforementioned sediment, etc. can be scooped up into the loading platform 41. It can be transported to the following location. Also, loading platform 41
When unloading the loaded earth and sand onto the ground, the hydraulic cylinder 36 is extended to tilt the loading platform 41, and the earth and sand slide on the inclined loading platform 41 and fall to the ground. In this case, since the front part 41a of the loading platform 41 is pivotally connected by hinges 45 and 45, if the front part 41a is flipped upward,
Earth and sand accumulated on the front portion 41a of the loading platform can be easily discharged.

FIG. 5 shows a transport vehicle for scooping and loading and unloading, with the front end 52 of the loading platform 51 open and the left and right side plates 53, 53
The rear plate 54 can be opened and closed using hinges 55, 55, and so on. Therefore, as shown in FIG. 6, the side plate 53.
By opening 53 and the rear plate 54, cargo can be easily loaded and unloaded onto the cargo platform 51 from all sides.

Here, as shown in FIG. 7, by extending the hydraulic cylinder 36 and tilting the loading platform 5I, the front end 52 of the loading platform comes into contact with the ground and can scoop up dirt, dust, etc. Furthermore,
The transport vehicle is brought close to the truck 37 and the inclined loading platform 5
When the rear plate 54 of 1 is opened to the truck 37 side, the loading platform 51 is constructed from the truck 37 to the ground, and cargo can be loaded and unloaded while sliding on the loading platform 51.

Figure 8 shows a transport vehicle that collects garbage on the ground.
A rotating brush 62 is provided at the front end of the left and right side plates 63.
63 and the rear plate 64, a frame body 65 is installed upright, and this frame body 65
A collector 67 is formed by covering the cloth 66 with the cloth 66. The rotating brush 62 is connected to a frame l along with a driving motor 68.
, 69, and the frame 69 has both side plates 63
．． 63 and can be rotated up and down.

As shown in the figure, if the hydraulic cylinder 36 is extended to tilt the loading platform 61 and the rotary brush 62 is rotated in the direction of the arrow by the drive of the motor 68 and brought into contact with the ground, the garbage scattered on the ground can be removed. It is scraped up and collected inside the collector 67. When the garbage stored in the collector 67 is to be transported to another location, the hydraulic cylinder 36 is contracted to return the loading platform 61 to a horizontal position, and the crawlers 28 and 28 are driven to advance the transport vehicle. Further, when the garbage stored in the collector 67 is to be disposed of, the loading platform 61 is flipped upward and tilted, and the garbage in the collector 67 is discharged to the ground.

In the transport vehicle shown in FIG. 9, one end 72 of a loading platform 71 is pivotally connected to a frame J2, so that the loading platform 71 can be opened and closed. Usually, cargo is placed on the top surface of the loading platform 71 and transported.
The engine 14, the mission case 15, the generator 16
When performing inspection or repair, the engine section I7 can be easily maintained by rotating the loading platform 71 upward to open the engine section I7. Although the loading platform 71 is provided with a pivoting portion at the rear, a pivoting portion may be provided at the side so that the loading platform 7I can be rotated laterally, or it may be slid to open and close.

Note that this invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that this invention extends to such modifications.

[Effects of the Invention] As described in detail in the above-mentioned embodiment, the present invention provides that the loading platform of a transport vehicle is extended at an angle, one end of the loading platform is close to the ground, and the other end is latched to the truck. A tilted loading platform is constructed between the vehicle and the ground, producing the same effect as a conventional tilted board. Therefore, the carrier can be used as an auxiliary means for loading and unloading cargo, and the conventional inclined plate is not required when working in a narrow space, making it possible to contribute to improving work efficiency.
