Description

Technical Field

[0001] The present invention relates to the technical field of shore container crane transportation, and in particular to a shore container crane and a shipping assembly method. Background Art

[0002] With the rapid development of the national and global economies, the port industry is increasingly moving towards inland ports, specialization, and large-scale development. As the main force of port equipment, quay cranes are increasingly in demand for inland port quay cranes.

[0003] When purchasing quay crane equipment at inland river terminals, due to limited clearance heights, they often ship in bulk and assemble it on-site. This solution requires renting large floating cranes at the terminal, which is costly and inefficient due to the impact of flood season water levels.

[0004] In related technologies, by setting up a door frame structure and an upper crossbeam structure, the quay crane can be self-lifted during installation using its own structural components and a winch system, which can improve assembly efficiency.

[0005] However, in the related art, when transporting the self-lifting quay crane structure, the upper crossbeam structure is placed on the door frame structure in advance. At this time, the highest point of the quay crane structure during transportation is the top of the door frame structure or the upper crossbeam structure exceeds the top of the door frame structure. The overall height of the structure easily exceeds the bridge clearance height, and there is room for improvement. Summary of the Invention

[0006] In view of this, the present invention provides a shore container crane and a shipping assembly method to solve the problem that the height of the shore crane exceeds the clearance height of the bridge during transportation.

[0007] In a first aspect, the present invention provides a shore container crane, comprising an upper door frame assembly, a lower door frame assembly and a rear-front beam assembly, wherein the lower door frame assembly comprises a placement site for placing the rear-front beam assembly, and the upper door frame assembly comprises an assembly site for installing the rear-front beam assembly; the shore container crane has a transport state and an assembly completion state, wherein, in the transport state, the lower door frame assembly is upright placed on the deck of a ship, the rear-front beam assembly is placed at the placement site of the lower door frame assembly, and the upper door frame assembly is placed on the deck of the ship; in the assembly completion state, the lower door frame assembly is upright placed at the target position, and in the vertical direction, the upper door frame assembly is installed above the lower door frame assembly, and the rear-front beam assembly is installed at the assembly site of the upper door frame assembly.

[0008] Beneficial effects: By splitting the door frame structure into an upper door frame assembly and a lower door frame assembly, the upper door frame assembly and the lower door frame assembly are separated during transportation, and assembled on-site during assembly, which greatly reduces the height of the door frame when the equipment is in transportation state, ensuring that the height of the quay crane during transportation can meet the clearance height of the bridge, thereby ensuring the reliability of quay crane transportation. At the same time, the lower door frame assembly and the rear-front beam assembly can be assembled in advance in the factory, which greatly reduces the workload of on-site assembly.

[0009] In an optional embodiment, the lower door frame assembly includes a land side lower cross beam, a sea side lower cross beam, two groups of lower door frame sheets arranged at relative intervals, and four groups of carts; the land side lower cross beam and the sea side lower cross beam are arranged at relative intervals at the same height, and the two groups of lower door frame sheets are respectively fixedly installed at both ends of the length of the land side lower cross beam, and the bottom of any lower door frame sheet on the sea side is fixedly connected to the top of the sea side lower cross beam, and the bottom of any lower door frame sheet on the land side is fixedly connected to the top of the land side lower cross beam; a group of carts are respectively installed at both ends of the length of the land side lower cross beam and both ends of the length of the sea side lower cross beam; the top surface of the sea side lower cross beam and the top surface of the land side lower cross beam constitute placement sites for placing the rear-front beam assembly.

[0010] Beneficial effects: The lower door frame assembly, consisting of the landside lower crossbeam, the seaside lower crossbeam, the lower door frame sheet and the trolley, can be assembled in advance in the factory, which greatly reduces the workload of on-site assembly and helps to improve on-site assembly efficiency.

[0011] In an optional embodiment, the upper door frame assembly includes two groups of upper door frame sheets arranged at relative intervals; in the transportation state, the two groups of upper door frame sheets are shipped separately, or the two groups of upper door frame sheets are stacked and shipped; in the final assembly completion state, in the vertical direction, the bottoms of the two groups of upper door frame sheets are respectively installed on the tops of the two groups of lower door frame sheets, and the two groups of upper door frame sheets are arranged at relative intervals at the same height, and the assembly site of the rear-front beam assembly is located at the upper part of the two groups of upper door frame sheets.

[0012] Beneficial effect: The upper door frame assembly consisting of two sets of upper door frame sheets can be placed flat on the deck of the ship during transportation, reducing the overall height of the quay crane door frame structure and ensuring that the height of the quay crane during transportation can meet the clearance height of the bridge. During assembly, the upper door frame sheets can be hoisted onto the corresponding underground door frame sheets, which is easy to install.

[0013] In an optional embodiment, the front-rear beam assembly includes a front beam, a rear beam, a ladder frame, a machine room, a trolley assembly, a towing system, a hanging cabin device, a winch, a pull rod, a pitching wire rope, a sea-side upper crossbeam and a land-side upper crossbeam; the ends of the front beam and the rear beam that are close to each other are hinged, and the hanging cabin device, the machine room, the land-side upper crossbeam and the sea-side upper crossbeam are all installed on the upper part of the rear beam, and the hanging cabin device, the machine room, the land-side upper crossbeam and the sea-side upper crossbeam are arranged in the length direction of the rear beam from the end away from the front beam to the end close to the front beam. The parts are arranged in sequence; the ladder frame is installed at the transportation position or the assembly position of the upper crossbeam on the sea side, the assembly position of the upper crossbeam on the sea side is higher than the transportation position of the upper crossbeam on the sea side, one end of the pull rod is hinged to the upper part of the upper crossbeam on the land side, and the other end of the pull rod is hinged to the upper part of the ladder frame; the winch is installed on the upper crossbeam on the land side, one end of the pitching wire rope is transmission-connected to the winch, and the other end of the pitching wire rope passes around the pulley at the ladder frame tower head and is wrapped around the pulley on the upper part of the front beam; the trolley assembly and the towing system are both installed at the lower part of the rear beam.

[0014] Beneficial effect: The rear-front beam assembly is lowered, and through the cooperation of the winch and the pitching wire rope, the front beam has the ability to do pitching movement relative to the rear beam, which is convenient for adjusting the posture of the rear-front beam assembly during transportation.

[0015] In an optional embodiment, in the transport state, the lower door frame assembly is placed upright on the deck of the ship, the rear beam is placed flat on the placement position on the lower door frame assembly, the length direction of the rear beam is parallel to the width direction of the ship, and the ladder frame is installed in the transport position of the upper beam on the sea side; the pitch wire rope is pulled by the winch to drive the front beam to rotate around the hinge point of the front beam and the rear beam, so as to lay the front beam flat or pull up; the rear-front beam assembly also includes a front beam pull rod, which is placed flat on the deck of the ship.

[0016] Beneficial effects: In the transport state, the front beam can be pulled up by the winch and the pitching wire rope. When crossing the bridge, the front beam can be lowered or even laid flat by the winch and the pitching wire rope, thereby reducing the height of the rear-front beam assembly when crossing the bridge and ensuring that the height of the quay crane during transportation can meet the clearance height of the bridge.

[0017] In an optional embodiment, in the final assembly completed state, the ladder frame is installed at the final assembly position of the upper crossbeam on the sea side; the rear-front beam assembly also includes a front beam pull rod, one end of the front beam pull rod is hinged to the upper part of the ladder frame, and the other end of the front beam pull rod is hinged to the front beam; the rear-front beam assembly is installed to the assembly position on the top of the upper door frame assembly.

[0018] Beneficial effect: When the final assembly is completed, the front beam tie rod is installed on the rear front beam assembly to ensure the normal function of the quay crane. In the transportation state, the front beam tie rod is not installed on the rear front beam assembly, which can increase the lifting range of the front beam relative to the rear beam, avoiding the front beam hanging too long outside the ship deck during the non-bridge crossing stage of transportation, thereby ensuring shipping safety.

[0019] In a second aspect, the present invention also provides a shipping assembly method for a shore container crane, which includes: in-factory installation: assembling the lower door frame assembly and the rear-front beam assembly to be shipped respectively, and then hoisting the assembled rear-front beam assembly to be shipped to the placement position of the lower door frame assembly to form a quay crane body in a transport state; loading: the ship docks sideways, towing the quay crane body in a transport state for loading, and hoisting the upper door frame assembly and the front beam pull rod for loading; unloading ashore: the ship docks sideways at the dock, towing the quay crane body in a transport state ashore to the back yard of the dock, and reserving support space for the front beam at the front edge of the dock; dock assembly: resetting and installing the components on the rear-front beam assembly according to the assembly requirements, resetting and installing the upper door frame assembly on the lower door frame assembly, and forming a quay crane body in an assembled state, and then towing the quay crane body in the assembled state to the front edge of the dock to drop onto the track, and then resetting and installing the reset rear-front beam assembly at the assembly position of the upper door frame assembly to complete the assembly.

[0020] Beneficial effects: Since the shipping assembly method of the shore container crane is applied to the shore container crane, it has the same effects as the shore container crane and will not be described in detail here.

[0021] In an optional embodiment, the method for resetting and installing the components on the rear-front beam assembly according to the final assembly requirements includes: using tooling to support the front beam, removing the pitch wire rope, hoisting and resetting the ladder frame to the final assembly position of the upper crossbeam on the sea side, hoisting and resetting the front beam pull rod to connect the ladder frame and the front beam, and then reinstalling the pitch wire rope.

[0022] Beneficial effect: Not installing the front beam pull rod during transportation can increase the tilting range of the front beam relative to the rear beam, ensuring transportation safety; and the front beam pull rod needs to be installed in place during assembly. Since the pitching wire rope is located at the upper part of the front beam pull rod, in order to install the front beam pull rod, the pitching wire rope needs to be removed first, and then reinstalled after the front beam pull rod is installed in place.

[0023] In an optional embodiment, the method for resetting and installing the rear-front beam assembly at the assembly site of the upper door frame assembly includes: using a self-lifting method to lift the reset rear-front beam assembly to the assembly site of the upper door frame assembly, and then positioning and installing the rear-front beam assembly and two sets of upper door frame panels.

[0024] Beneficial effects: The self-lifting method can reduce the use of large floating cranes during assembly, is less affected by river water levels during flood season, and helps improve assembly efficiency.

[0025] In an optional embodiment, the method for resetting and installing the upper door frame assembly on the lower door frame assembly includes: respectively lifting the two groups of upper door frame sheets to the upper part of the corresponding underground door frame sheets, using flange bolts to fix the upper door frame sheets and the corresponding underground door frame sheets, or using welding to fix the upper door frame sheets and the corresponding underground door frame sheets.

[0026] Beneficial effect: The upper door frame sheet and the lower door frame sheet are fixedly connected by a flange bolt pair or welding, which can effectively control the assembly height of the whole machine, and is simple to operate and has high installation efficiency.

[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0042] The following combination Figures 1 to 11 , describing embodiments of the present invention.

[0043] According to an embodiment of the present invention, in one aspect, a shore-to-shore container crane is provided, comprising an upper door frame assembly 1, a lower door frame assembly 2, and a rear-front beam assembly 3. The lower door frame assembly 2 includes a placement location for placing the rear-front beam assembly 3, and the upper door frame assembly 1 includes an assembly location for installing the rear-front beam assembly 3. The shore-to-shore container crane has a transport state and a final assembly state. In the transport state, the lower door frame assembly 2 is placed upright on the deck of a vessel 4, the rear-front beam assembly 3 is placed at the placement location of the lower door frame assembly 2, and the upper door frame assembly 1 is placed on the deck of the vessel 4. In the final assembly state, the lower door frame assembly 2 is placed upright at the target location, the upper door frame assembly 1 is vertically mounted above the lower door frame assembly 2, and the rear-front beam assembly 3 is mounted at the assembly location of the upper door frame assembly 1.

[0044] The technical solution of this application is to split the door frame structure into an upper door frame assembly 1 and a lower door frame assembly 2. The upper door frame assembly 1 and the lower door frame assembly 2 are separated during transportation, which greatly reduces the height of the door frame when the equipment is in the transportation state, ensures that the height of the quay crane during transportation can meet the clearance height of the bridge, and thus ensures the reliability of quay crane transportation. During assembly, the lower door frame assembly 2 and the upper door frame assembly 1 are assembled on-site at a designated location at the target wharf, and by pre-assembling the lower door frame assembly 2 and the rear-front beam assembly 3 in the factory, the on-site assembly workload is greatly reduced, and the efficiency of shipping assembly is improved.

[0045] In one embodiment, the lower door frame assembly 2 includes a landside lower crossbeam 201, a seaside lower crossbeam 202, two sets of lower door frame panels 203 spaced apart from each other, and four sets of carts 204. The landside lower crossbeam 201 and the seaside lower crossbeam 202 are spaced apart from each other at the same height. The two sets of lower door frame panels 203 are fixedly mounted at either end of the length of the landside lower crossbeam 201. The bottom of each lower door frame panel 203 facing the seaside is fixedly connected to the top of the seaside lower crossbeam 202, and the bottom of each lower door frame panel 203 facing the landside is fixedly connected to the top of the landside lower crossbeam 201. A set of carts 204 is mounted at each end of the length of the landside lower crossbeam 201 and the seaside lower crossbeam 202. The top surfaces of the seaside lower crossbeam 202 and the landside lower crossbeam 201 form the placement sites for the rear and front beam assemblies 3. The lower door frame assembly 2, consisting of the landside lower crossbeam 201, the seaside lower crossbeam 202, two sets of lower door frame panels 203, and four sets of carts 204, can be pre-assembled in the factory and loaded and unloaded from a ship via roll-on / roll-off transport, making transportation easy. Furthermore, during transport, the placement of the lower door frame assembly 2 also serves as a support base for the rear-front beam assembly 3.

[0046] Furthermore, the upper door frame assembly 1 includes two groups of upper door frame sheets 101 that are relatively spaced apart. In the transport state, the two groups of upper door frame sheets 101 are loaded onto the ship separately, or the two groups of upper door frame sheets 101 are stacked and loaded onto the ship, thereby reducing the overall height of the quay crane door frame structure. In the final assembly state, in the vertical direction, the bottoms of the two groups of upper door frame sheets 101 are respectively installed on the tops of the two groups of lower door frame sheets 203, and the two groups of upper door frame sheets 101 are relatively spaced apart at the same height, and the assembly site of the rear-front beam assembly 3 is located on the upper part of the two groups of upper door frame sheets 101. The final assembly of the upper door frame sheets 101 and the lower door frame sheets 203 can be connected by flange bolt pairs or by welding. On the one hand, this can ensure the structural strength of the door frame, and on the other hand, it is simple to operate and has high installation efficiency.

[0047] Furthermore, the front-rear beam assembly 3 includes a front beam 301, a rear beam 302, a ladder frame 303, a machine room 304, a trolley assembly 305, a festoon system 306, a nacelle device 307, a winch 308, a pull rod 309, a pitching wire rope 3010, a sea-side upper crossbeam 3011, and a land-side upper crossbeam 3012. The front beam 301 and the rear beam 302 are hinged at their adjacent ends, allowing the front beam 301 to rotate relative to the rear beam 302. The hanger assembly 307, the machinery room 304, the landside upper crossbeam 3012, and the seaside upper crossbeam 3011 are all mounted on top of the rear beam 302. They are arranged in order along the length of the rear beam 302, from the end furthest from the front beam 301 to the end closest to the front beam 301. The ladder frame 303 is mounted on the seaside upper crossbeam 3011 at either the transport or assembly position. The assembly position of the seaside upper crossbeam 3011 is higher than the transport position. By arranging different mounting positions on the seaside upper crossbeam 3011, the height of the ladder frame 303 remains below the bridge clearance during transport. One end of the tie rod 309 is hinged to the top of the landside upper crossbeam 3012, while the other end is hinged to the top of the ladder frame 303. A hoist 308 is mounted on the landside upper crossbeam 3012. One end of a pitching wire rope 3010 is in driving connection with the hoist 308. The other end of the pitching wire rope 3010 passes over a pulley at the tower head of the ladder frame 303 and then around a pulley mounted on the upper portion of the front beam 301. Both the trolley assembly 305 and the festoon system 306 are mounted on the lower portion of the rear beam 302.

[0048] In the transport state, the lower door frame assembly 2 is placed upright on the deck of the vessel 4, with the rear beam 302 resting flat on the lower door frame assembly 2 at its placement location. The length of the rear beam 302 is parallel to the width of the vessel 4, and the ladder frame 303 is mounted on the seaside upper crossbeam 3011 in its transport position. The winch 308 pulls the pitching wire rope 3010, driving the front beam 301 to rotate about the hinge point between the front beam 301 and the rear beam 302, thereby leveling or raising the front beam 301. The rear-front beam assembly 3 also includes a front beam tie rod 3013, which rests flat on the deck of the vessel 4. During non-bridge transport, the winch 308 pulls the pitching wire rope 3010 to lift the front beam 301. The extent to which the front beam 301 is raised can be adjusted based on actual conditions to prevent the front beam 301 from overhanging the deck of the vessel 4 during non-bridge transport, ensuring safe shipping. It should be noted that the highest point of the raised front beam 301 may or may not be higher than the lower door frame assembly 2. If the highest point of the raised front beam 301 is higher than the lower door frame assembly 2, the raising range of the front beam 301 can be reduced during the bridge crossing stage, or the front beam 301 can even be laid flat to lower the highest point of the rear-front beam assembly 3, ensuring that the highest point of the rear-front beam assembly 3 is lower than the bridge clearance height.

[0049] After final assembly, the ladder frame 303 is installed at the final assembly location on the seaside upper crossbeam 3011. The rear-front beam assembly 3 also includes a front beam tie rod 3013, one end of which is hinged to the upper portion of the ladder frame 303 and the other end of which is hinged to the front beam 301. The pitch wire rope 3010 is located outside the front beam tie rod 3013. The rear-front beam assembly 3 is installed at the assembly location at the top of the upper door frame assembly 1.

[0050] According to an embodiment of the present invention, in another aspect, a shipping assembly method for a shore container crane is provided, the shipping assembly method comprising:

[0051] Factory Installation: Separately assemble the lower door frame assembly 2 and the rear-front beam assembly 3 to be shipped. The assembled rear-front beam assembly 3 is then hoisted to the lower door frame assembly 2's placement location, forming the quay crane body 5 in its transport state. Specifically, the landside lower crossbeam 201, the seaside lower crossbeam 202, two sets of lower door frame segments 203, and four sets of trolleys 204 are assembled in the factory. The front beam 301, rear beam 302, ladder frame 303, machine room 304, trolley assembly 305, trolley system 306, and nacelle device 307 are assembled in the factory. The pitching wire rope 3010 is pulled by a winch 308 extending from the landside upper crossbeam 3012, passing around the ladder frame 303 tower head and the pulleys on the front beam 301, pulling and securing the front beam 301.

[0052] Loading: The ship 4 is docked, the quay crane body 5 in the towing transport state is loaded onto the ship, and the upper door frame assembly 1 and the front beam tie rod 3013 are hoisted and loaded onto the ship. Figure 7 As shown, two sets of quay crane bodies 5 are placed on the deck of the vessel 4, with their lengths parallel to the width of the vessel 4. Two sets of upper door frame assemblies 1 and two sets of front beam tie rods 3013 are placed flat on the open space on the deck of the vessel 4. It should be further noted that the quay crane bodies 5, upper door frame assemblies 1, and front beam tie rods 3013 can all be secured to designated locations on the deck of the vessel 4 by lashing.

[0053] Unloading and landing: The ship 4 is parked at the dock, and the quay crane body 5 in the transport state is pulled ashore to the back yard of the dock, and a supporting space for the front beam 301 is reserved at the front edge of the dock.

[0054] Since the bottom of the quay crane body 5 is composed of four groups of trolleys 204, the quay crane body 5 can be loaded or unloaded by traction roll-on / roll-off, without the need for a large floating crane.

[0055] Final assembly at the wharf: Reset and install the components on the rear-front beam assembly 3 according to the final assembly requirements, reset and install the upper door frame assembly 1 on the lower door frame assembly 2, and form the quay crane body 5 in the final assembly state. Then, tow the quay crane body 5 in the final assembly state to the front edge of the wharf and drop it onto the track. After that, reset the rear-front beam assembly 3 and reset it at the assembly position of the upper door frame assembly 1 to complete the final assembly.

[0056] In one embodiment, a method for reinstalling components on the rear-front beam assembly 3 according to final assembly requirements includes: using a tool 6 to support the front beam 301, removing the pitching wire rope 3010, hoisting and reinstalling the ladder frame 303 to the final assembly position on the seaside upper crossbeam 3011, hoisting and reinstalling the front beam tie rod 3013 to connect the ladder frame 303 and the front beam 301, and then reinstalling the pitching wire rope 3010. Not installing the front beam tie rod 3013 during transportation can increase the tilting range of the front beam 301 relative to the rear beam 302, ensuring transportation safety. However, during final assembly, the front beam tie rod 3013 must be installed in place. Since the pitching wire rope 3010 is located above the front beam tie rod 3013, the pitching wire rope 3010 must be removed before installing the front beam tie rod 3013. After the front beam tie rod 3013 is installed in place, the pitching wire rope 3010 is reinstalled.

[0057] In one embodiment, the method for resetting and installing the rear-front beam assembly 3 at the assembly site of the upper door frame assembly 1 includes: using a self-lifting method to lift the reset rear-front beam assembly 3 to the assembly site of the upper door frame assembly 1, and then positioning and installing the rear-front beam assembly 3 and the two sets of upper door frame plates 101. The use of a self-lifting method can reduce the use of large floating crane equipment during assembly, is less affected by the river water level during flood season, and helps to improve assembly efficiency. It should be emphasized that the self-lifting method used in this application can be any self-lifting method used for quay crane assembly in the existing technology. The self-lifting method is not the focus of the technical solution protection of this application and will not be described in detail here.

[0058] In one embodiment, a method for resetting and installing the upper door frame assembly 1 on the lower door frame assembly 2 includes: hoisting two sets of upper door frame segments 101 to the upper parts of corresponding underground door frame segments 203, and fixing the upper door frame segments 101 and the corresponding underground door frame segments 203 with flange bolts, or fixing the upper door frame segments 101 and the corresponding underground door frame segments 203 with welding. Fixing the upper door frame segments 101 and the lower door frame segments 203 with flange bolts or welding can effectively control the assembly height of the entire machine, simplify the operation, and improve installation efficiency.

[0059] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
