Description

  The present invention provides a moving path to the hull side of a truck in the vicinity of a quay when transferring a load from the land to the ship's body, especially in the case of a load such as earth and sand. The present invention relates to a self-propelled ramp device for shipping intended for use as a vehicle.

  Conventionally, roadbeds for shipping have been stored in factories and other places, and when used, they are transported to the site using a trailer. In such a case, when loading into the trailer, a large crane is required twice when the trailer is unloaded, so the large crane and the trailer had to be borrowed whenever necessary.

  In addition to the above, in the construction of a structure such as a dam, there has been a case where a ramp is installed that allows the vehicle to travel over the step formed at the boundary between the blocks. In addition, a mobile erection bridge to be placed in the harbor has been proposed.

Patent No. 342133 JP2000-336952

  In the conventional method, when a roadbed is required, a large crane is rented whenever a trailer is borrowed, loaded with a roadbed and carried to the site, and when the roadbed is loaded, or when the roadbed is installed on the spot. All of them had a problem that they had to borrow every time they were installed.

  Also, if a roadbed was permanently installed on the quay, there was a risk that it would be in the way when it was not needed, and it was necessary to remove it when it was not in use, especially at public wharves. In addition, depending on the type of ship, there are a number of problems such as requiring a change in the installation location or having to occupy a large area without being used even when not in use.

  Conventionally, in construction of a dam or the like, there is known an invention of a ramp that allows a vehicle to travel by overcoming a step generated between the blocks by placing concrete for each block (Patent Document 2). This ramp is not self-propelled and will become unnecessary as the dam construction ends. .

  There has also been proposed an invention of a device that inserts a traveling frame into the lower part of an erected bridge and transports the erected bridge by the traveling frame (Patent Document 1). The device is originally composed of an erection bridge and its traveling gantry, and is not integrated, and in principle is a horizontal road surface, and is used when an oblique road surface (or no tilting) is not required. It will be unnecessary after the end and will not be used again.

  The present invention solves the above-mentioned conventional problems by providing a self-propelled ramp device for loading in which a roadbed and a self-propelled vehicle are integrated, and satisfies the request as a roadbed for loading. is there.

  That is, the roadbed can be installed at the best position and angle by directing it to the required place when necessary, as in the case where the roadbed is tiltably installed on the track base, for example. Therefore, not only is the borrowing of the trailer unnecessary, but also a large crane is unnecessary, and inevitably the personnel who move the trailer are also unnecessary. Since the movement of the upper roadbed is basically the same as the operation of the truck, it can be moved to a necessary place and installed when necessary. In addition, it is possible to respond immediately to conditions such as being able to respond immediately even if the landing position of the quay is changed. Furthermore, since the roadbed and the self-propelled vehicle are integrated, the location, inclination, installation status, etc. of the roadbed can be adjusted according to the site.

  That is, according to this invention, the roadbed for loading is placed on the upper part of the self-propelled vehicle, and the lifting device for the roadbed is provided between the front portion of the self-propelled vehicle and the front portion of the roadbed. An intermediate portion of the self-propelled vehicle is rotatably connected, and at least two support legs are connected to the front portion of the roadbed so as to be adjustable in length to support the roadbed on the ground, and a rear end of the roadbed A self-propelled ramp device for loading, characterized in that an auxiliary board that closes the difference between the roadbed and the road surface is pivotally connected to the section, provided with a non-slip uneven portion on the surface of the roadbed, A shield plate reaching the inside of the hull is connected to the tip portion so as to be suspended.

  Further, the lifting device is a hydraulic jack or a screw jack installed between the front base of the self-propelled vehicle and the front lower surface of the roadbed, and the self-propelled vehicle is attached to the cart built on the wheels. The driver's cab, the control device, and the drive device are installed, and the two support legs are installed at an oblique position with respect to the leading edge of the roadbed so as to be parallel to the ship wall.

  Although the conventional material and external shape of the roadbed can be used as they are, the attachment of the roadbed and the self-propelled vehicle (for example, a track-like portion) is unique and easy to operate. What must be installed is a vertical hoisting device (jack) and a rotatable attachment for adjusting the tilt of the roadbed. In addition, since the upper surface shape of the connecting portion between the roadbed and the road must always be made smooth, an auxiliary board is required. It is necessary to rotate this auxiliary board so that it does not get in the way during self-running and to be stacked on the edge of the roadbed. In addition, it is necessary to suspend the lower shielding plate from the tip of the roadbed so that earth and sand are scattered when thrown into the hull.

  In the present invention, the tiltable means that the intermediate portion of the roadbed can be changed in angle (about 12 degrees to 15 degrees) with respect to the horizontal centering on the axis 10 (FIG. 1 (a)) perpendicular to the longitudinal direction (the roadbed). Slope adjustment). Specifically, the front of the roadbed is raised or lowered by a support tool (jack). When the angle is determined as described above, the road base is securely supported by contacting the support leg to the ground. Since the truck runs on the roadbed, the roadbed must be securely fixed.

  The lifting device according to the present invention may employ a hydraulic jack, a screw jack or other hoisting device.

  The center line in the longitudinal direction of the roadbed of the invention is often inclined (plan view) with respect to the quay (ship). The reason is that the road along the quay is narrow, making it difficult to enter a large truck or other roadbed. Therefore, if there is enough plaza for the truck to change direction, the roadbed will be installed at right angles to the quay.

  In the above description, if the distance L (FIG. 2) between the roadbed edge (auxiliary board edge A) and the road edge B is equal to or larger than the width necessary for turning the truck (90-degree direction change), the roadbed It is preferable that the front edge C and the ship wall be at right angles. However, since the road width along the quay is often not large enough, the installation angle of the roadbed (angle with respect to the quay) can be adjusted between 90 and 45 degrees to make it easier for the incoming truck to enter. (FIG. 4). As a result, the truck loading time is greatly improved, the cargo handling time is shortened, and the economic effect is great.

  However, the roads along the quay are often narrow, and there are few roads that are so wide that trailers (large trucks) can bend at right angles.

  In the present invention, the roadbed is a self-propelled system and can tilt, and the truck travels on the roadbed to withstand the weight and vibration when the load is unloaded. That is, it is characterized in that the traveling function (cart) and the support function (support leg) are separated.

  According to the present invention, the roadbed can be easily installed or removed, and the roadbed can be installed or removed without using a trailer or a large crane. In addition, when loading wharfs, gaps can be used effectively to match narrow places on the quay, and the roadbed can be easily moved to the best place for loading (or unloading position) by ship berthing. It is possible to always select the best shipping position.

Enlarged view. FIG. (A) The front view of the state which installed the roadbed to the quay similarly, (b) The enlarged front view of the auxiliary roadbed vicinity vicinity. FIG. The top view of the other Example of a roadbed similarly.

  In this invention, a roadbed for loading is placed on an upper part of a self-propelled vehicle (for example, a truck-like vehicle body) and fixed so as to be tiltable, and a lifting device such as a jack is installed on the lower surface of the front part of the roadbed. A rear lower part is rotatably attached to the self-propelled vehicle. With the above structure, the inclination of the roadbed can be adjusted by raising and lowering the front part of the roadbed. Further, a support leg is installed on the lower surface of the roadbed so as to be extendable and retractable so that the front portion of the roadbed can be supported at the best height. In addition, an auxiliary board is rotatably attached to the rear end of the roadbed so that there is no drop between the road surface and the roadbed, thereby facilitating the transition of the track.

  Furthermore, since the shielding plate is suspended from the front edge of the tip portion of the roadbed, it is possible to prevent the cargo from being scattered to the lower surface side of the roadbed even when the load is gravel.

  As described above, when installing the roadbed, the need for a trailer and a large crane is eliminated, and the installation angle of the roadbed (accuracy with respect to the horizontal plane and angle with respect to the quay) can be arbitrarily selected.

  In addition, in the public wharf, the roadbed must be set and removed every time a ship is loaded and unloaded, but this invention makes it very easy to set and remove. Although cargo handling of a ship is limited in time, it can meet the demand.

  An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The self-propelled vehicle 5 has wheels 2 and 3 installed before and after the carriage 1 and a drive system for the wheels 2 and 3. It can be driven in the same way as a truck. A roadbed 6 is placed on the upper side of the carriage 1, a lower end of a rear portion 6b of the roadbed 6 and the carriage 1 are rotatably attached by a fixture 16, and a lower surface of the front portion 6a of the roadbed 6 and a carriage The jack 7 is interposed between the front part 1a of 1. The jack 7 is an instrument for raising and lowering the front portion 6 a of the roadbed 6, and is screwed into a screw 8 attached to the carriage 1 and a nut 9 fixed to the roadbed 6. Accordingly, if the drive shaft 22 is rotated to rotate the bevel gear 17 and the bevel gear 18 meshing with the bevel gear 17 is rotated, the screw 8 is rotated. When the nut 9 moves up and down to raise and lower the front portion of the roadbed 6, the roadbed 6 rotates about the shaft 10 and the inclination of the roadbed can be adjusted. Further, since the front end portion of the auxiliary board 11 is attached to the rear end portion of the roadbed 6 by the hinge 17, this is rotated as indicated by an arrow 32 to fill the step between the rear portion of the roadbed and the road surface 21. The movement of the track 40 can be made smooth. In the figure, 33 is a stopper for the auxiliary board 11 (FIG. 3). The inclination of the roadbed 6 is adjusted to 12 degrees to 15 degrees. However, when the inclination is 13 degrees or more, the continuity of the inclination between the auxiliary roadbed 11 and the roadbed 6 is maintained via the bush 45. (FIG. 3B).

  On the lower surface of the front portion of the roadbed 6 is fixed an upper portion of a leg rod 12 that can be adjusted in length. A screw part 12a is provided in the lower part of the leg rod 12, and a leg board 13 is screwed into the screw part 12a (FIG. 1 (c)). Therefore, if the base 13 is rotated, the base 13 is moved up and down as indicated by an arrow 20 by the screw portion 12a of the leg 12. When installing the roadbed 6, the legboard 13 is rotated and lowered, and when the lower surface of the legboard 13 comes into contact with the ground 21, the bolts 22 penetrating the legboard 13 are used to The leg board 13 is fixed (it is not limited to this structure).

  When the roadbed 6 is to be removed, the bolts 22 are removed, the legboard 13 is rotated, the legboards 13 are raised along the leg pads 12, and the bolts 22 are removed when the lower surface of the legboard 13 is sufficiently separated from the ground. If fixed with, there is no risk of hindering the movement of the roadbed 6.

  Next, referring to FIG. 1C, the lower end 6 c of the front portion 6 a of the roadbed 6 is supported by the upper end portion of the piston rod 23, and the piston 24 connected to the lower end of the rod 23 is inserted into the hydraulic cylinder 25. In the above, when the oil is supplied from the oil supply pipe 26 as indicated by arrow 27, the piston 24 is pushed up hydraulically as indicated by arrow 28, so the front portion 6c of the roadbed 6 also rises in the same direction, and the inclination of the roadbed 6 suddenly increases. Become. Contrary to the above, if the oil is discharged from the oil supply pipe 26 as indicated by arrow 29, the piston rod 23 descends as indicated by arrow 30, so that the inclination of the roadbed 6 becomes gentle (for example, 12 degrees to 15 degrees adjustment). it can).

  As described above, when the piston 24 and the hydraulic cylinder 25 are used, the piston rod 23 is moved up and down by supply and discharge of pressurized oil through the oil supply pipe 26, and the front portion 6a of the roadbed 6 is adjusted to be high or low. Can do.

  Referring to FIGS. 3 and 4, an embodiment of the present invention (sediment pile) will be described. In order to install the roadbed 6 on the quay 31, the self-propelled vehicle 5 is driven and the roadbed 6 is carried to be placed on the quay 31. With the front part of the roadbed 6 overlaid above the quay 31, the inclination of the roadbed 6 is adjusted using a jack. Specifically, the front portion of the roadbed 6 is raised so that the rear end portion of the roadbed 6 abuts (closes to) the ground surface 21, the stopper 33 (FIG. 1) is removed, and the auxiliary board 11 is indicated by an arrow 32. To close the gap between the roadbed 6 and the ground 21. On the other hand, the leg board 13 is rotated and moved until its lower surface touches the ground, and then the bolt 22 is screwed to fix the leg board 13 to the ground 21. A shielding plate 34 is suspended from the front edge of the roadbed 6, and the lower edge reaches the inside of the hull 35. The shielding plate 34 can prevent earth and sand from scattering from the inside of the ship to the lower surface side of the roadbed 6.

  In the embodiment of FIG. 3, when the truck 40 loaded with earth and sand is moved backward to the front end of the roadbed 6 and the loading platform 39 of the truck 40 is rotated as indicated by arrow 38, the earth and sand 37 is moved by the weight of arrow 36. And is housed in the hull 35. In the figure, 41 is a water surface, and 42 is a slip stopper (for example, round bars are fixed by welding at small intervals) provided on the upper surface of the roadbed.

  If a plane triangular auxiliary piece 44 is connected to the front side of the roadbed 6 (FIG. 5), the truck 40 faces the hull 35 at a right angle even if the quay 31 and the roadbed 6 are skewed. Stop and achieve stable input of earth and sand.
