[0023] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.
[0024] In combination with Figures 1 to 4 As shown in the drawings, the present application provides a novel heavy cargo wharf, which comprises an upstream trestle 2, a downstream trestle 3, two gantry cranes 4 and a downstream beam transport trestle 5. The downstream beam transport trestle 5, the upstream trestle 2 and the downstream trestle 3 are arranged in parallel on the horizontal plane. The downstream beam transport trestle 5 is located on the side of the downstream trestle 3 facing the upstream trestle 2. The upstream trestle 2 and the downstream beam transport trestle 5 enclose a ship berthing area. Each gantry crane 4 is arranged on the upstream trestle 2 and the downstream trestle 3 and can move along the extension direction of the upstream trestle 2 and the downstream trestle 3. The downstream beam transport trestle 5 is provided with a mobile beam transport vehicle 6.
[0025] Specifically, the wharf foundation 1 refers to the ground pile fixed on the wharf. The upstream trestle 2 and the downstream trestle 3 have the same structure, and in the direction of the river flow, the upstream trestle 2 is located upstream, and the downstream trestle 3 is located downstream. The upstream trestle 2 and the downstream trestle 3 respectively include a land part fixed on the ground pile on the wharf foundation 1 and a water part extending above the river and erected by a plurality of adjacent pier columns. The downstream beam conveying trestle 5, the upstream trestle 2 and the downstream trestle 3 are horizontally parallel and erected. The downstream beam conveying trestle 5 is located between the upstream trestle 2 and the downstream trestle 3 and is erected on the side of the downstream trestle 3 facing the upstream trestle 2, that is, close to the downstream trestle 3. The area between the upstream trestle 2 and the downstream beam conveying trestle 5 is used as a ship berthing area. After the ship is berthed in the ship berthing area, the ship will be affected by the flow of water and will move towards the downstream area. In this embodiment, the area between the upstream trestle 2 and the downstream beam conveying trestle 5 is used as a ship berthing area, so that the ship can move close to the downstream beam conveying trestle 5 under the influence of the water flow, and there will be no situation that the distance between the ship and the downstream beam conveying trestle 5 is too large to effectively and safely load and unload goods. Each gantry crane 4 is movably connected to the upstream trestle 2 and the downstream trestle 3 along the length direction of the upstream trestle 2 and the downstream trestle 3. The downstream beam conveying trestle 5 is provided with a movable beam conveying vehicle 6. When the goods do not need to be transferred, the two gantry cranes 4 and the movable beam conveying vehicle 6 are located on the land part of the downstream beam conveying trestle 5, the upstream trestle 2 and the downstream trestle 3. When the goods need to be transferred, the novel heavy cargo wharf in the utility model is at least applicable to the following situations:
[0026] Case one:
[0027] If the transferred goods are kilotonnage large steel beam segments, after the ship is berthed in the ship berthing area, the two gantry cranes 4 jointly lift the kilotonnage large steel beam segments. After the two gantry cranes 4 are moved from the land part to the water part of the upstream trestle 2 and the downstream trestle 3, the two gantry cranes 4 realize the transfer of the kilotonnage large steel beam segments from the land to the water, so that the two gantry cranes 4 can realize the launching and unloading operation of the kilotonnage large steel beam segments.
[0028] Case two:
[0029] If the transferred goods are relatively small steel beam segments, after the ship is berthed in the ship berthing area, one gantry crane 4 close to the river side lifts the steel beam segments, and only one gantry crane 4 close to the river side transfers the relatively small steel beam segments to the ship.
[0030] Case three:
[0031] If the transported goods are small rods with relatively small weight, the gantry crane 4 near the river side lifts the small rods after the ship docks in the ship docking area, and the small rods are transported to the mobile beam transport vehicle 6 on the land. The mobile beam transport vehicle 6 transports the small rods to the ship along the downstream beam trestle 5.
[0032] Therefore, in the embodiment, the downstream beam trestle 5, the upstream trestle 2 and the downstream trestle 3 are arranged in parallel on the horizontal plane, the downstream beam trestle 5 is located on the side of the downstream trestle 3 facing the upstream trestle 2, the upstream trestle 2 and the downstream beam trestle 5 form the ship docking area, each gantry crane 4 is arranged on the upstream trestle 2 and the downstream trestle 3 and can move along the extension direction of the upstream trestle 2 and the downstream trestle 3, and the two gantry cranes 4 can move reciprocally between the land and the ship docking area along the upstream trestle 2 and the downstream trestle 3, so that the two gantry cranes 4 can be selectively used for lifting or only one gantry crane 4 is used for lifting according to the weight of the steel beam section, the application range of the wharf is improved, the use efficiency of the wharf is improved, the mobile beam transport vehicle 6 is arranged on the downstream beam trestle 5, the mobile beam transport vehicle 6 can transport small goods such as small rods, the gantry crane 4 can be avoided for lifting small goods, the energy consumption of the gantry crane 4 is reduced, the application range of the wharf is further improved to improve the use efficiency of the wharf, and efficient, energy-saving and safe loading and unloading of different types of components are realized.
[0033] Optionally, the first guide rail is arranged on the upstream trestle 2 and the downstream trestle 3, and the first guide rail extends along the extension direction of the upstream trestle 2 and the downstream trestle 3. Each gantry crane 4 is in sliding connection with the first guide rail.
[0034] Specifically, the first guide rail is arranged on the bridge deck of the upstream trestle 2 and the downstream trestle 3, respectively, and extends along the extension direction of the upstream trestle 2 and the downstream trestle 3. Each gantry crane 4 is in sliding connection with the first guide rail arranged on the upstream trestle 2 and the downstream trestle 3, so as to realize the movement guidance of each gantry crane 4.
[0035] In this way, the first guide rail arranged on the upstream trestle 2 and the downstream trestle 3 extends along the extension direction of the upstream trestle 2 and the downstream trestle 3, and each gantry crane 4 is in sliding connection with the first guide rail. The first guide rail can realize the movement guidance of each gantry crane 4, so as to ensure the movement accuracy of each gantry crane 4 and the efficiency of the goods transportation.
[0036] Optionally, the second guide rail is arranged on the downstream beam trestle 5, and the second guide rail extends along the extension direction of the downstream beam trestle 5. The mobile beam transport vehicle 6 is in sliding connection with the second guide rail.
[0037] Specifically, the second guide rail can be made of an I-beam. The second guide rail is laid on the downstream beam transport trestle 5 and extends along the extension direction of the downstream beam transport trestle 5. The moving beam trolley 6 is in sliding connection with the second guide rail to guide the movement of the moving beam trolley 6.
[0038] In this way, the second guide rail laid on the downstream beam transport trestle 5 extends along the extension direction of the downstream beam transport trestle 5, and the moving beam trolley 6 is in sliding connection with the second guide rail. The second guide rail can guide the movement of the moving beam trolley 6, ensure the accuracy of the movement of the moving beam trolley 6, and ensure the efficiency of the cargo transfer.
[0039] Optionally, in combination with Figure 2 As shown, the middle part of the downstream beam transport trestle 5 in the bridge width direction is higher than the two ends in the bridge width direction.
[0040] Specifically, the bridge width direction of the downstream beam transport trestle 5 refers to the X-axis direction of the downstream beam transport trestle 5. The middle part of the downstream beam transport trestle 5 in the bridge width direction is higher than the two ends in the bridge width direction, that is, the middle part of the bridge of the downstream beam transport trestle 5 is high, and the two ends are low.
[0041] In this way, by arranging the middle part of the downstream beam transport trestle 5 in the bridge width direction to be higher than the two ends in the bridge width direction, the river water or rainwater on the bridge of the downstream beam transport trestle 5 can flow from the middle part to the two ends in the bridge width direction, thereby improving the drainage efficiency and avoiding the influence of the river water or rainwater on the bridge of the downstream beam transport trestle 5 on the movement of the moving beam trolley 6, thereby improving the cargo transfer efficiency of the moving beam trolley 6.
[0042] Optionally, in combination with Figure 2 As shown, the downstream beam transport trestle 5 and the downstream trestle 3 are connected by a plurality of connection cross beams 7 arranged in parallel.
[0043] Specifically, the connection cross beams 7 are horizontally distributed, and the two ends of the connection cross beams 7 in the length direction are connected to the downstream beam transport trestle 5 and the downstream trestle 3 by heavy load bolts, respectively.
[0044] In this way, by connecting the downstream beam transport trestle 5 and the downstream trestle 3 by a plurality of connection cross beams 7 arranged in parallel, the plurality of connection cross beams 7 can avoid the collision between the downstream beam transport trestle 5 and the downstream trestle 3, and also ensure that the distance between the downstream beam transport trestle 5 and the downstream trestle 3 is constant, so that the downstream beam transport trestle 5 and the downstream trestle 3 remain parallel, thereby avoiding the inclination of the extension direction of the downstream beam transport trestle 5 affecting the movement accuracy of the moving beam trolley 6.
[0045] Optionally, in combination with Figure 1 As shown, each gantry crane 4 is provided with an anti-swing trolley 8 for magnetically attracting a steel plate.
[0046] Specifically, each gantry crane 4 is provided with an anti-swing trolley 8. The anti-swing trolley 8 is movably arranged on the upper beam of the gantry crane 4 and can move horizontally along the length direction of the upper beam of the gantry crane 4, that is, the X-axis direction. When the transported goods are steel plates, the gantry crane 4 close to the river side is moved to the ship docking position, the steel plates are transported to the lower side of the anti-swing trolley 8 by the moving beam trolley 6, the anti-swing trolley 8 is magnetically attracted and lifted to move to the designated steel plate loading and unloading area on the ship, then the anti-swing trolley 8 releases the magnetic attraction of the steel plate to transport the steel plate to the ship. The specific structure of the anti-swing trolley 8 can be realized by existing technical means. For example, the anti-swing trolley 8 can include a magnetic attraction execution end and a driving end for driving the movement of the magnetic attraction execution end. The driving end is movably arranged on the upper beam of the gantry crane 4 along the length direction of the upper beam of the gantry crane 4. When the magnetic attraction execution end is magnetically attracted to the steel plate, the driving end drives the movement of the magnetic attraction execution end to move the steel plate to the loading and unloading area on the ship, and then the magnetic attraction execution end releases the magnetic attraction of the steel plate to load and unload the steel plate on the ship. In this way, the steel plate lifting operation can be quickly performed to avoid the delay of the steel plate loading and unloading at the wharf, thereby improving the efficiency of the steel plate loading and unloading.
[0047] Optionally, the water area part is arranged on the river surface by means of a pier column, and a collision-proof roller rubber fender is arranged on the pier column.
[0048] Specifically, the roller rubber fender can be realized by existing technical means. The water area parts of the upstream trestle 2, the downstream beam trolley trestle 5 and the downstream trestle 3 are arranged on the river surface by means of a pier column, and a collision-proof roller rubber fender is arranged on the pier column. The roller rubber fender can avoid collision between the ship and the pier column when the ship is docked, thereby improving safety.
[0049] Optionally, the new heavy cargo wharf further includes a wharf berthing traction system for the ship to dock. In this way, the new heavy cargo wharf can adapt to the docking of different ships through the wharf berthing traction system, thereby improving the adaptability of the new heavy cargo wharf.
[0050] Optionally, each gantry crane 4 is a 1000-ton gantry crane 4. In this way, the two gantry cranes 4 can cooperate with each other to lift 2000-ton heavy cargo, thereby improving the maximum rated weight of the new heavy cargo wharf.
[0051] Optionally, in combination with Figure 2 As shown in the figure, the downstream beam trolley trestle 5 is provided with anti-collision guardrails 9 at both ends in the bridge width direction.
[0052] Specifically, the anti-collision guardrails 9 are respectively arranged at both ends of the downstream beam trolley trestle 5 in the bridge width direction, and the moving beam trolley 6 moves between the two anti-collision guardrails 9.
[0053] Therefore, the anti-collision guardrails 9 are arranged at two ends of the downstream beam transporting trestle 5 in the bridge width direction, and the anti-collision guardrails 9 can ensure the moving safety of the mobile beam transporting vehicle 6.
[0054] Although the utility model discloses as above, the protection scope of the utility model is not limited to this only.The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will all fall into the protection scope of the utility model.
