Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically to a marine spherical flat steel clamping lifting equipment. Background Technology

[0002] In the shipbuilding and related industries, marine bulb flat steel is a commonly used steel material. Due to its special shape, special lifting equipment is required during handling, hoisting and on-site transfer to ensure the safety and efficiency of the operation.

[0003] Traditional methods for lifting marine bulb flats have several drawbacks. Firstly, some lifting equipment has a relatively simple structure, only capable of basic lifting functions, and lacks effective binding and restraint measures for stacked marine bulb flats. During lifting, the marine bulb flats are prone to swaying, shifting, or even scattering, which not only increases the difficulty and risk of the lifting operation but may also damage the marine bulb flats, affecting project progress and quality.

[0004] On the other hand, traditional lifting equipment has limited functionality and lacks wire rope storage capabilities. After lifting operations, the wire ropes are often stored haphazardly, easily becoming tangled with other tools or equipment. This not only takes up space but also requires significant time for organization and inspection before the next use, reducing work efficiency. Furthermore, when multiple stacks of marine bulb flats need to be moved short distances on-site, traditional methods typically require the use of large equipment such as forklifts. This not only increases equipment and labor costs but also limits the efficiency of moving marine bulb flats in confined spaces where forklifts cannot operate flexibly.

[0005] Therefore, developing a marine spherical flat steel clamping and lifting device that can solve the above problems is of great practical significance. Summary of the Invention

[0006] The purpose of this invention is to provide a marine flat steel clamping and lifting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a marine flat steel clamping and lifting device, comprising two sets of lifting plates, which are respectively placed on the upper and lower sides of stacked marine flat steel, and each set of lifting plates has two plates. The ends of the two sets of lifting plates are connected by steel wire ropes. Both ends of the lifting plates are provided with wire harness grooves, the ends of the steel wire ropes are inserted into the wire harness grooves, clamping blocks are inserted into the wire harness grooves, and pressure plates are fixed on the surface of the clamping blocks. The pressure plates are installed on the lifting plates by screws.

[0008] The surface of the hoisting plate is provided with a storage groove for storing the disassembled wire rope;

[0009] The surface of the hoisting plate is equipped with multiple pulleys that rotate.

[0010] Preferably, both ends of the hoisting plate are provided with side grooves, and a bolting rod is fixed between the two parallel side walls of the side groove. One end of the wire rope is bolted to the bolting rod and then inserted into the wire harness groove.

[0012] Preferably, the surface of the pressure plate has an installation opening, which is an "I"-shaped round opening. The interior of the installation opening is rotatably connected to an "I"-shaped round handle. A screw is fixed to one end of the handle. The surface of the lifting plate has a screw hole, and the screw and the screw hole are connected in a mating manner.

[0013] Preferably, the other end of the handle is provided with a circular groove, and a screw handle is fixed inside the circular groove. The screw handle has a cross-shaped plate structure.

[0014] Preferably, a limiting plate is fixed to one end of the pressure plate, and the limiting plate abuts against one side of one side wall of the side groove.

[0015] Preferably, baffles are fixed at both ends of the lifting plate, and the two baffles abut against the two sides of the stacked marine flat steel.

[0016] Preferably, the surface of the lifting plate has two symmetrically distributed reserved slots, and lifting rings are fixed inside the reserved slots.

[0017] Preferably, the width of the storage groove is smaller than the width of the hoisting plate, the rubber cover has an "L" shaped plate structure, and one end of the rubber cover has a notch.

[0018] Preferably, multiple wheel grooves are provided on both sides of the lifting plate, the pulley is located in the wheel groove, and a limit shaft is movably inserted into the surface of the pulley.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The marine flat steel clamping and lifting device proposed in this invention not only achieves bundling and positioning of stacked marine flat steel through the lifting plate, but also serves as a lifting structure. The lifting rings fixed in the pre-reserved groove facilitate connection with a lifting machine for lifting operations. Simultaneously, it functions as a wire rope storage structure, solving the problem of wire rope storage. Furthermore, it also facilitates the sliding movement of stacked marine flat steel. This multi-functional design significantly improves the utilization rate of the lifting device, reduces the types and quantity of equipment, and lowers production and management costs, demonstrating significant comprehensive advantages.

[0031] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 9This invention provides a technical solution: a marine flat steel clamping and lifting device, comprising two sets of lifting plates 1, which are respectively placed on the upper and lower sides of stacked marine flat steel 2, and each set of lifting plates 1 has two plates. The ends of the two sets of lifting plates 1 are connected by steel wire ropes 5. Both ends of the lifting plates 1 are provided with wire harness grooves 6, and the ends of the steel wire ropes 5 are inserted into the wire harness grooves 6. Both ends of the lifting plates 1 are provided with side grooves 3, and bolt rods 4 are fixed between the two parallel side walls of the side grooves 3. One end of the steel wire rope 5 is bolted to the bolt rod 4 and then inserted into the wire harness groove 6. Both ends of the lifting plates 1 are fixed with baffles 24, and the two baffles 24 respectively abut against the two sides of the stacked marine flat steel 2. Two symmetrically distributed reserved grooves 16 are opened on the surface of the lifting plates 1, and lifting rings 17 are fixed inside the reserved grooves 16.

[0033] In use, first place a set of lifting plates 1 on the ground, then stack multiple marine flat steel bars 2 together, and finally place another set of lifting plates 1 on top of the stacked marine flat steel bars 2. Next, tie one end of the wire rope 5 to the connecting rod 4 at one end of one set of lifting plates 1, and then straighten and tighten the other end of the wire rope 5 and tie it to the connecting rod 4 at one end of the other set of lifting plates 1. It should be noted that after the two ends of the wire rope 5 are tied, the length is reserved to be inserted into the cable tray 6. Tie the wire rope 5 to both ends of the lifting plate 1 in this way. At this time, the two sets of lifting plates 1 placed symmetrically are connected by two taut wire ropes 5 to clamp and limit the stacked marine flat steel bars 2. Fix the hook or rope of the lifting machine to the lifting ring 17, and then lift the stacked marine flat steel bars 2 with the help of the lifting machine.

[0034] To achieve anti-derailment reinforcement of the wire rope 5 after it is bolted to the bolting rod 4, the following was proposed:

[0035] A clamping block 7 is inserted inside the cable duct 6, and a pressure plate 9 is fixed on the surface of the clamping block 7. The pressure plate 9 is installed on the lifting plate 1 by a screw 12. The cable duct 6 is a U-shaped groove, and the clamping block 7 is a U-shaped plate. Multiple slots 8 are opened on the side of the clamping block 7 near the wire rope 5. An installation port 10 is opened on the surface of the pressure plate 9. The installation port 10 is an I-shaped round opening. An I-shaped round handle 11 is rotatably connected inside the installation port 10. The screw 12 is fixed to one end of the handle 11. A screw hole 13 is opened on the surface of the lifting plate 1. The screw 12 and the screw hole 13 are connected. A round groove is opened at the other end of the handle 11. A screw handle 14 is fixed inside the round groove. The screw handle 14 is a cross-shaped plate structure. A limit plate 15 is fixed to one end of the pressure plate 9. The limit plate 15 abuts against one side of one side wall of the side groove 3.

[0036] The reinforcement procedure for the steel wire rope 5 after it is bolted to the bolted rod 4 is as follows:

[0037] After the end of the wire rope 5 is inserted into the cable tray 6, the bottom end of the screw 12 is guided into the screw hole 13. The screw 12 is pushed into the screw hole 13 by hand by squeezing the screw handle 14. Since the limiting plate 15 is on one side of the side groove 3, it prevents the pressure plate 9 from swinging during the fall. As the screw 12 is pushed in, the clamping block 7 is inserted into the cable tray 6. After the screw 12 is continued to be screwed in, the clamping block 7 tightly clamps the wire rope 5 inside the cable tray 6. The spring force of the wire rope 5 under pressure supports the clamping block 7 and the pressure plate 9, so that the screw 12 and the screw hole 13 are tightly connected. The clamping block 7 clamps the wire rope 5 to prevent the wire rope 5 from falling off the end of the lifting plate 1.

[0038] In order to store the disassembled wire rope 5 and lifting plate 1 together, the following was proposed:

[0039] The surface of the lifting plate 1 is provided with a storage groove 21 for storing the disassembled wire rope 5. The width of the storage groove 21 is smaller than the width of the lifting plate 1. The rubber cover 22 has an "L" shaped plate structure, and a notch 23 is provided at one end of the rubber cover 22. When the wire rope 5 is removed from the end of the lifting plate 1, the rubber cover 22 is stretched from the notch 23, making the notch 23 larger. The neatly wound wire rope 5 is inserted into the storage groove 21 from the notch 23. After the rubber cover 22 is released, the rubber cover 22 springs back and wraps the wire rope 5 in the storage groove 21, thus protecting the wire rope 5 stored inside the storage groove 21.

[0040] To enable the on-site sliding transfer of multiple stacked marine flat steel bars 2, the following method was proposed:

[0041] Multiple pulleys 20 are rotatably mounted on the surface of the lifting plate 1. Multiple wheel grooves 18 are opened on both sides of the lifting plate 1, and the pulleys 20 are located in the wheel grooves 18. The surface of the pulleys 20 is movably connected to the limiting shafts 19, which are T-shaped round rods. One end of the limiting shafts 19 is fixed to the side wall of the wheel grooves 18. The pulleys 20 on both sides of the lifting plate 1 at the bottom of the stacked marine flat steel 2 contact the ground, and the lifting plate 1 is lifted and suspended in the air. In fact, there is no need for a forklift. The workers can push the stacked marine flat steel 2 to slide and transfer it on site.

[0042] The lifting plate 1 not only binds and limits the stacked marine flat steel 2, but also serves as a lifting structure, a storage structure for the wire rope 5, and a means for the stacked marine flat steel 2 to slide and move. In other words, the lifting plate 1 is multi-functional and has many uses.

[0043] Instructions for using marine flat steel clamping spreaders:

[0044] Place a set of lifting plates 1 smoothly on the ground, ensuring the surface of the lifting plates 1 is flat and without tilting. Stack multiple marine flat steel bars 2 one by one on the already placed lifting plates 1, ensuring the stacking is neat and the center of gravity of the marine flat steel bars 2 is stable. Place another set of lifting plates 1 on top of the stacked marine flat steel bars 2, making the two sets of lifting plates 1 symmetrical, with the baffles 24 at both ends of the lifting plates 1 abutting against the sides of the stacked marine flat steel bars 2, providing initial positioning. Take a steel wire rope 5 and tie one end of it to the bolting rod 4 at one end of one set of lifting plates 1, ensuring a secure connection. Stretch the other end of the steel wire rope 5 taut, and then tie it to the bolting rod 4 at one end of the other set of lifting plates 1. After tying, leave enough length at both ends of the steel wire rope 5 to fit into the cable tray 6. Following the above method, a steel wire rope 5 is also attached to the other end of the lifting plate 1. At this time, the two sets of lifting plates 1, which are symmetrically placed vertically, are connected by two taut steel wire ropes 5 to clamp and limit the stacked marine flat steel 2. After the end of the steel wire rope 5 is inserted into the cable tray 6, it is ready to reinforce the steel wire rope 5. The bottom end of the screw 12 is inserted into the screw hole 13 opened on the surface of the lifting plate 1. The screw 12 is pushed into the screw hole 13 by hand by squeezing the screw handle 14 (the screw handle 14 is a cross-shaped plate structure, located in the circular groove opened at the other end of the handle 11, the handle 11 is an I-shaped round block, which is rotatably connected to the pressure plate 9 through the mounting port 10, and the screw 12 is fixed to one end of the handle 11). The screw 12 is pushed into the screw hole 13. Since the limiting plate 15 fixed at one end of the pressure plate 9 abuts against one side of the side wall of the side groove 3, it can prevent the pressure plate 9 from swinging during the fall. As the screw 12 advances, the clamping block 7 (a U-shaped plate with multiple slots 8 on the side near the wire rope 5) is inserted into the cable tray 6. Continue to screw the screw 12 forward, causing the clamping block 7 to tightly hold the wire rope 5 inside the cable tray 6. The springback force of the wire rope 5 under pressure supports the clamping block 7 and the pressure plate 9, ensuring a tight connection between the screw 12 and the screw hole 13, thus clamping the wire rope 5 and preventing it from falling off the end of the lifting plate 1. Reinforce the other wire rope 5 using the same method. Secure the hook or rope of the lifting machine to the lifting ring 17 fixed inside the pre-reserved slot 16 on the surface of the lifting plate 1. Start the lifting machine, slowly raise the hook, and lift the stacked marine flat steel 2 to a suitable height for transfer or placement in a designated location. During the lifting process, carefully observe the lifting situation to ensure safe and stable lifting. When storing the wire rope and lifting plate, disassemble the wire rope: unscrew the screw 12 of the reinforcing wire rope 5 from the screw hole 13, remove the clamp 7, untie the wire rope 5 from the bolt rod 4, and remove the wire rope 5 from the end of the lifting plate 1. Locate the storage groove 21 (the width of the storage groove 21 is less than the width of the lifting plate 1) on the surface of the lifting plate 1. Tension the rubber cover 22 (which has an "L"-shaped plate structure with a notch 23 at one end) through the notch 23 to enlarge the groove of the notch 23. Insert the neatly wound wire rope 5 into the storage groove 21 through the notch 23.Release the rubber cover 22, and the rubber cover 22 will spring back to its original position, wrapping the steel wire rope 5 in the storage groove 21, thus protecting the steel wire rope 5 stored inside the storage groove 21. When transferring the marine flat steel, prepare for sliding: ensure that the pulleys 20 on both sides of the lifting plate 1 at the bottom of the stacked marine flat steel 2 (multiple pulleys 20 are rotatably mounted on the surface of the lifting plate 1, and multiple wheel grooves 18 are opened on both sides of the lifting plate 1, with the pulleys 20 positioned in the wheel grooves 18, and a limiting shaft 19 movably inserted into the surface of the pulley 20, the limiting shaft 19 being a "T"-shaped round rod, one end fixed to the side wall of the wheel groove 18) are in contact with the ground, and that the ground is flat and free of obstructions. After the lifting plate 1 is lifted and suspended, without the need for a forklift, workers can push the stacked marine flat steel 2, allowing it to slide across the site via the pulleys 20 to the designated location. During the sliding process, pay attention to controlling the pushing speed and direction to ensure safety. After use, conduct a comprehensive inspection of all components, including the lifting platform 1 and wire rope 5, to check for any damage or wear. If necessary, repair or replace them promptly. Store the lifting platform 1 and wire rope 5 in a dry, well-ventilated place to prevent moisture, rust, and damage.
