Description

Technical Field

[0001] This utility model relates to the field of hoisting and transportation technology, specifically a highly safe cylindrical section transfer hoisting tool. Background Technology

[0002] Lifting and transportation is a process that uses lifting equipment (such as cranes, hoists, tower cranes, etc.) to vertically and horizontally move heavy objects (such as large equipment, components, and goods) from one location to another. It combines the two key links of lifting (vertical lifting and movement) and transportation (horizontal movement) and is commonly used in construction sites, factories, ports, docks, and other places to handle heavy and large objects that cannot be moved by manpower or conventional transportation tools.

[0003] However, in actual use, the transfer of cylindrical sections is a critical link in the manufacturing process of large equipment. When traditional lifting tools are used to lift large cylindrical sections, the weight and special shape of the sections can easily lead to imbalance, resulting in sliding, shaking or even falling off, which seriously threatens the life safety of on-site personnel and the integrity of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a highly safe cylindrical section transfer lifting tool to solve the problem mentioned in the background art. In the process of manufacturing large equipment, the transfer of cylindrical sections is a critical link. When lifting large cylindrical sections, traditional lifting tools are prone to weight imbalance due to the large weight and special shape of the cylindrical sections, which can lead to slippage, shaking or even falling off, seriously threatening the life safety of on-site personnel and the integrity of equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a lifting beam, with lifting lugs fixedly installed at the four corners of the upper end of the lifting beam for connection with a crane; protective covers are fixedly installed on both sides of the lower end of the lifting beam; an internally threaded transmission pipe is rotatably connected to the outer center of the protective cover via a rotating shaft; a clamping arm for clamping the cylinder section is fixedly installed on the inner side of the internally threaded transmission pipe; first limiting slide rods are fixedly installed on both sides of the outer end of the clamping arm; a U-shaped connecting beam is fixedly installed at the upper end of the lifting beam; a first control motor is fixedly installed at the upper end of the U-shaped connecting beam; a first synchronous pulley is fixedly installed on the outer drive shaft portion of the first control motor; a second synchronous pulley is connected to the outer end of the first synchronous pulley via a synchronous belt; a transmission shaft is fixedly installed in the middle of the second synchronous pulley; third synchronous pulleys are fixedly installed on both sides of the transmission shaft; a fourth synchronous pulley is connected to the outer end of the third synchronous pulley via a synchronous belt; a first transmission screw is threadedly connected to the inner wall of the internally threaded transmission pipe; and a second limiting slide rod is fixedly installed on the inner side of the upper end of the lifting beam.

[0006] A second control motor is fixedly installed on the outer side of the upper end of the lifting beam. A second transmission screw is fixedly installed on the inner drive shaft of the second control motor. A counterweight is threadedly connected to the outer curved surface of the middle part of the second transmission screw. A third limiting slide rod is movably connected through and fitted at both ends of the counterweight.

[0007] Preferably, there are four lifting lugs, which are symmetrically distributed at the four corners of the upper end of the lifting beam. A power control cabinet is fixedly installed on the outer side of the upper end of the lifting beam, and a mobile power supply is fixedly installed inside the power control cabinet.

[0008] Preferably, there are two protective covers, which are symmetrically distributed on both sides of the lower end of the lifting beam, and the clamping arm is attached with an anti-slip pad.

[0009] Preferably, the outer side of the first limiting slide rod is connected to the outer end of the protective cover through a through-hole fit, and the transmission shaft is rotatably connected to the upper end of the lifting beam through a bearing seat.

[0010] Preferably, the fourth synchronous pulley is fixedly mounted on the outer curved surface of the internal thread transmission tube, the screws on the outer curved surface of the first transmission screw face opposite directions, and the inner side of the first transmission screw is fixedly mounted on the outer end of the clamping arm.

[0011] Preferably, a limiting block is fixedly installed at the upper end of the clamping arm, and the limiting block is movably connected through and fits the outer curved surface of the second limiting slide rod.

[0012] Preferably, the second transmission screw is rotatably connected to the middle of the lifting beam through a rotating shaft, and the third limiting slide rod is fixedly installed on both sides of the inner side of the lifting beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the lifting beam is moved during hoisting, the first control motor is activated. When the first control motor is activated, it drives the fourth synchronous wheel to rotate synchronously, which in turn drives the internal thread transmission tube to rotate synchronously. The outer curved screw of the first transmission screw faces opposite directions, so that when the internal thread transmission tube rotates synchronously, the force generated by the threaded connection drives the first transmission screw to move synchronously outward or inward. When the first transmission screw moves synchronously inward, it drives the clamping arm to move linearly inward. When the clamping arm moves linearly inward, the cylinder section can be clamped and hoisted.

[0015] This invention also addresses the issue of imbalance occurring during the clamping and hoisting of the cylinder section. By activating a second control motor, the second transmission screw is driven to rotate. This rotation, due to the force generated by the threaded connection, causes the counterweight to move linearly left and right. This linear movement of the counterweight adjusts its position, thereby facilitating the adjustment of its configuration during hoisting and achieving balance in the cylinder section.

[0021] Please see Figure 1-3This utility model provides a high-safety cylindrical section transfer lifting device technical solution: it includes a lifting beam 1, which is made of high-strength alloy steel material, has sufficient strength and rigidity, and can bear the weight of large cylindrical sections. The four corners of the upper end of the lifting beam 1 are fixedly installed with lifting lugs 2 for connecting with a crane. There are four lifting lugs 2, which are symmetrically distributed at the four corners of the upper end of the lifting beam 1. A power control cabinet 3 is fixedly installed on the outer side of the upper end of the lifting beam 1, and a mobile power supply is fixedly installed inside the power control cabinet 3.

[0022] Protective covers 4 are fixedly installed on both sides of the lower end of the lifting beam 1. There are two protective covers 4, symmetrically distributed on both sides of the lower end of the lifting beam 1. The outer center of the protective cover 4 is rotatably connected to an internal threaded transmission pipe 5 via a rotating shaft. A clamping arm 6 for clamping the cylinder section is fixedly installed on the inner side of the internal threaded transmission pipe 5. The clamping arm 6 is bonded with an anti-slip pad to prevent the cylinder section from sliding during hoisting. The outer sides of the clamping arm 6 are fixedly installed with first limiting slide rods 7. The outer side of the first limiting slide rods 7 is connected to the outer end of the protective cover 4 through and fits snugly, so that the clamping arm 6 is linearly limited by the first limiting slide rods 7. A U-shaped connecting beam 8 is fixedly installed on the upper end of the lifting beam 1. A first control motor 9 is fixedly installed on the upper end of the U-shaped connecting beam 8. A first synchronous pulley 10 is fixedly installed on the outer drive shaft of the first control motor 9. The outer end of the first synchronous pulley 10 is connected to a second synchronous pulley via a synchronous belt. The second synchronous wheel 11 has a transmission shaft 12 fixedly installed in the middle, and the transmission shaft 12 is rotatably connected to the upper end of the lifting beam 1 through a bearing seat. The third synchronous wheel 13 is fixedly installed on both sides of the transmission shaft 12. The outer end of the third synchronous wheel 13 is connected to the fourth synchronous wheel 14 through a synchronous belt. The middle of the fourth synchronous wheel 14 is fixedly installed on the outer curved surface of the internal thread transmission tube 5. The inner wall of the internal thread transmission tube 5 is threadedly connected to the first transmission screw 15, and the screws on the outer curved surface of the first transmission screw 15 face opposite directions. The inner side of the first transmission screw 15 is fixedly installed on the outer end of the clamping arm 6. The inner side of the upper end of the lifting beam 1 is fixedly installed on the second limiting slide rod 16. The upper end of the clamping arm 6 is fixedly installed on the limit block 17, and the limit block 17 is movably connected through and fits the outer curved surface of the second limiting slide rod 16, so that the clamping arm 6 is further linearly limited by the limit block 17 and the second limiting slide rod 16.

[0023] A second control motor 18 is fixedly installed on the outer side of the upper end of the lifting beam 1. A second transmission screw 19 is fixedly installed on the inner drive shaft of the second control motor 18. The second transmission screw 19 is rotatably connected to the middle of the lifting beam 1 through a rotating shaft. A counterweight 20 is threadedly connected to the outer curved surface of the middle of the second transmission screw 19. A third limiting slide rod 21 is movably connected to both ends of the counterweight 20. The third limiting slide rod 21 is fixedly installed on both sides of the inner side of the lifting beam 1, so that the counterweight 20 can be linearly moved and limited by the third limiting slide rod 21.

[0024] Working Principle: In use, this utility model connects to an external crane via the lifting lug 2. When the lifting lug 2 is connected to the external crane, the external crane can be controlled to lift and move the lifting beam 1 via the lifting lug 2. When the lifting beam 1 is lifted and moved, the first control motor 9 is activated. When the first control motor 9 is activated, it drives the first synchronous pulley 10 to rotate. When the first synchronous pulley 10 rotates, it drives the second synchronous pulley 11 to rotate via a synchronous belt drive. When the second synchronous pulley 11 rotates, it drives the transmission shaft 12 to rotate. When the transmission shaft 12 rotates, it synchronously drives the third synchronous pulley 12 to rotate. When the step wheel 13 rotates, the third synchronous wheel 13 will drive the fourth synchronous wheel 14 to rotate synchronously via the synchronous belt. When the fourth synchronous wheel 14 rotates synchronously, it will drive the internal thread transmission tube 5 to rotate synchronously. The outer curved screw of the first transmission screw 15 faces the opposite direction, so that when the internal thread transmission tube 5 rotates synchronously, the force generated by the threaded connection will drive the first transmission screw 15 to move synchronously outward or inward. When the first transmission screw 15 moves synchronously inward, it will drive the clamping arm 6 to move linearly inward. When the clamping arm 6 moves linearly inward, the cylinder section can be clamped and lifted.

[0025] When an imbalance occurs during the clamping and hoisting of the cylinder section, the second control motor 18 is activated. When the second control motor 18 is activated, it drives the second transmission screw 19 to rotate. When the second transmission screw 19 rotates, the force generated by the threaded connection drives the counterweight block 20 to move linearly left and right. When the counterweight block 20 moves linearly left and right, the counterweight position of the counterweight block 20 is adjusted, thereby facilitating the adjustment of the configuration position during hoisting of the cylinder section and achieving the effect of balancing the cylinder section during hoisting.
