[0012] Compared with the prior art, the utility model has the following beneficial effects: the temporary support device for the stern ramp of a roll-on / roll-off ship is provided with an elastic moving mechanism, so that the device has the function of being fixed and limited when in use and being easy to move when not in use. When the device is used, it can be applied to supports at different positions, and the support height of the device can be changed by increasing the number of connecting blocks. At the same time, since the device contacts the two layers of the first support plate of the stern ramp of the roll-on / roll-off ship, it can better contact the stern ramp of the roll-on / roll-off ship, thereby supporting the stern ramp of the roll-on / roll-off ship and preventing the swaying due to the uneven bottom end surface of the stern ramp of the roll-on / roll-off ship;

[0013] The temporary support device for the stern ramp of a roll-on / roll-off ship slides through a universal wheel. When the device is subjected to force, first, a suitable number of connecting blocks are installed at one end of the threaded column, and then the first supporting plate is installed at the upper end of the connecting block. Then, the threaded sleeve is driven to rotate by the adjusting rod, so that the threaded column is lifted and moved. The threaded column will drive the first supporting plate to a suitable height, so as to support the stern ramp of the roll-on / roll-off ship. When the stern ramp of the roll-on / roll-off ship contacts the first supporting plate, the upper plate and the lower plate of the first supporting plate rotate relatively, so that the rubber block on the upper end surface of the upper plate is closely fitted to the stern ramp of the roll-on / roll-off ship, so as to avoid shaking due to the uneven bottom end surface of the stern ramp of the roll-on / roll-off ship. When the first support rod and the second support rod are subjected to pressure, the outer cylinder shell and the inner cylinder shell slide, the base and the limiting leg move downward, and the second support plate drives the rubber pad to move downward and contact the ground. At this time, the second support plate drives the rubber pad to contact the ground, and the device is limited, so that the device has the function of being fixed when in use and easy to move when not in use. When the device is not in use, since the device is not subjected to force, the first support rod and the second support rod do not deform, so that the second support plate drives the rubber pad not to contact the bottom surface, and only the universal wheel contacts the bottom surface, so that the device moves;

[0014] The temporary support device for the stern ramp of a roll-on / roll-off ship is used to support the stern ramp of a roll-on / roll-off ship of different heights by adding different numbers of connecting blocks. At the same time, the device is easy to move, thereby saving installation time and improving work efficiency. At the same time, since the first support plate in the device is supported by the fixed block, the rotating shaft, the bearing, the upper plate, the lower plate, the second telescopic rod and the rubber block, when the upper plate is subjected to force, the upper plate and the lower plate form a rotating structure rotating around the bearing center through the fixed block, the rotating shaft and the bearing, and the second telescopic rod supports the upper plate, thereby facilitating the upper plate to fit the bottom end surface of the stern ramp of the roll-on / roll-off ship, and facilitating the support of the stern ramp of the roll-on / roll-off ship. Moreover, due to the special structure of the rubber block, relative sliding between the first support plate and the stern ramp of the roll-on / roll-off ship is avoided, and shaking when the device supports the stern ramp of the roll-on / roll-off ship is prevented.

[0024] When the device is subjected to force, firstly, a suitable number of connecting blocks 5 are installed at one end of the threaded column 401, and then the first supporting plate 6 is installed on the upper end surface of the connecting block 5, and then the threaded sleeve 402 is driven to rotate by the adjusting rod 403, so that the threaded column 401 can be lifted and lowered, and the threaded column 401 will drive the first supporting plate 6 to a suitable height to support the stern ramp of the ro-ro ship. When the stern ramp of the ro-ro ship contacts the first supporting plate 6, the upper plate 601 and the lower plate 602 in the first supporting plate 6 rotate relative to each other, so that the rubber block 604 on the upper end surface of the upper plate 601 is closely attached to the stern ramp of the ro-ro ship, so as to avoid shaking due to the uneven bottom end surface of the stern ramp of the ro-ro ship. At this time, since the device is subjected to pressure, the first supporting plate 6 The rod 303 and the second support rod 304 are deformed, and the outer cylinder shell 3011 and the inner cylinder shell 3012 slide, the base 1 and the limiting leg 2 move downward, and the second support plate 8 drives the rubber pad 9 to move downward and contact the bottom surface. At this time, the device is limited because the second support plate 8 drives the rubber pad 9 to contact the ground, and then the device is limited, so that the device has the function of fixed limit when in use and easy to move when not in use. When the device is not in use, since the device is not subjected to force, the first support rod 303 and the second support rod 304 are not deformed, so that the second support plate 8 drives the rubber pad 9 not to contact the bottom surface, and only the universal wheel 305 contacts the bottom surface, so that the device can move;

The installation time is saved and the work efficiency is improved. At the same time, since the first support plate 6 in the device is composed of a fixed block, a rotating shaft, a bearing, an upper plate 601, a lower plate 602, a second telescopic rod 603 and a rubber block 604, when the upper plate 601 is subjected to force, the upper plate 601 and the lower plate 602 use the fixed block, the rotating shaft and the bearing to form a rotating structure around the bearing center, and the second telescopic rod 603 supports the upper plate 601, so that the upper plate 601 is convenient for fitting with the bottom end surface of the stern ramp of the roll-on / roll-off ship, and it is also convenient to support the stern ramp of the roll-on / roll-off ship. Due to the special structure of the rubber block 604, relative sliding between the first support plate 6 and the stern ramp of the roll-on / roll-off ship is avoided, and shaking when the device supports the stern ramp of the roll-on / roll-off ship is prevented.

[0026] Working principle: When a temporary support device for the stern ramp of a roll-on / roll-off ship is used, when the device is subjected to force, firstly, an appropriate number of connecting blocks 5 are installed at one end of the threaded column 401, and then the first supporting plate 6 is installed on the upper end surface of the connecting block 5, and then the adjusting rod 403 is used to drive the threaded sleeve 402 to rotate, so that the threaded column 401 is moved up and down, and the threaded column 401 will drive the first supporting plate 6 to a suitable height to support the stern ramp of the roll-on / roll-off ship. When the stern ramp of the roll-on / roll-off ship contacts the first supporting plate 6, the upper plate 601 and the lower plate 602 in the first supporting plate 6 rotate relative to each other, so that the rubber block 604 on the upper end surface of the upper plate 601 fits tightly against the stern ramp of the roll-on / roll-off ship. At this time, due to the pressure on this device, the first support rod 303 and the second support rod 304 are deformed, and sliding occurs between the outer cylinder shell 3011 and the inner cylinder shell 3012, the base 1 and the limiting leg 2 move downward, and the second support plate 8 drives the rubber pad 9 to move downward and contact the bottom surface. At this time, the second support plate 8 drives the rubber pad 9 to contact the ground, and this device is limited, so that this device is limited. When this device is not in use, since this device is not subjected to force, the first support rod 303 and the second support rod 304 are not deformed, so that the second support plate 8 drives the rubber pad 9 not to contact the bottom surface, and only the universal wheel 305 contacts the bottom surface, so that this device moves.
