Description

Technical Field

[0001] This utility model relates to the field of steel structure hoisting technology, specifically a steel structure hoisting device. Background Technology

[0002] Steel structures can be classified into profiles, plates, pipes, and composite structures according to their shape and use, covering multiple application scenarios such as construction and industry. I-beams, as commonly used profile steel structures, have an "I"-shaped cross-section and have the advantages of both bending strength and lightweight, making them the core choice for load-bearing components such as beams and columns.

[0003] Lifting devices are lifting equipment that rely on mechanical structures and power systems. They are primarily used for lifting, moving, and precisely placing heavy objects. They are widely applicable to industrial construction, logistics transportation, and other scenarios. As a core piece of high-efficiency lifting equipment, lifting devices use components such as hooks and booms in conjunction with power output to achieve the safe lifting and spatial transfer of heavy objects.

[0004] Existing hoisting equipment uses clamps to hold I-beams and then lifts them with hooks. However, when using the clamps, the jaws need to be tightened by rotating the screw, but the screw has a large resistance when rotating, which reduces the clamping speed of the I-beam.

[0005] Therefore, a steel structure hoisting device is proposed to address the above problems. Utility Model Content

[0008] Preferably, the mounting assembly includes a mounting ring; the mounting ring and the screw are in a sliding fit; both the mounting ring and the screw are threaded with bolts; by using bolts to connect the mounting ring and the screw, they can be quickly fixed by threaded engagement during connection, thereby increasing convenience when disassembling and repairing the handle.

[0010] Preferably, the end of the handle is provided with an identification groove; the identification groove and the handle are correspondingly provided; by adding the identification groove, when the screw is rotated, it is possible to quickly determine which direction is connected to the first and second grippers.

[0011] Preferably, a sponge strip is fixed to the side wall of the handle; multiple sponge strips are provided on the handle; by adding sponge strips, the contact area can be increased by the deformation of the sponge strips when the handle is held, thereby increasing the friction during contact and reducing slippage when the handle is rotated.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the embodiment of this utility model, a steel structure hoisting device includes a base 1, with multiple drive components 11 disposed on the top of the base 1; an adjusting arm 12 is fixedly connected to the middle of the base 1; a fixing frame 13 is fixedly connected to the end of the adjusting arm 12; a servo motor 14 is fixedly connected to the side wall of the fixing frame 13; a winding wheel 15 is fixedly connected to the output end of the servo motor 14; a hoisting rope 16 is fixedly connected to the middle of the winding wheel 15; a connecting hook 17 is fixedly connected to the bottom of the hoisting rope 16; and a first gripper is disposed in the middle of the connecting hook 17. 18; A second gripper 19 is rotatably connected to the middle of the first gripper 18; a fixing rod 105 is rotatably connected to the middle of both the first gripper 18 and the second gripper 19; a screw 101 is rotatably connected to the middle of the fixing rod 105 on the first gripper 18; the screw 101 and the fixing rod 105 on the second gripper 19 are threadedly connected; a rocker arm 103 is connected to the end of the screw 101 through a mounting assembly 102; a handle 104 is rotatably connected to the end of the rocker arm 103; during operation, it is first used via a servo motor. Machine 14 controls the winding reel 15 to rotate, releasing the hoisting rope 16, thereby lowering the first gripper 18 and the second gripper 19. During descent, the first gripper 18 and the second gripper 19 can be placed on the side of the I-beam. Then, the handle 104 is grasped and rotated. Rotation of the handle 104 drives the screw 101 to rotate via the rocker arm 103. When the screw 101 rotates, it pushes the second gripper 19 closer to the first gripper 18. As they approach, the first gripper 18 and the second gripper 19 gradually move towards the I-beam. The handle 104 is clamped and connected to the I-beam. Once connected, the adjusting arm 12 is activated via the drive assembly 11 to hoist the I-beam. After prolonged use, the handle 104 can be disassembled via the mounting assembly 102. By adding the handle 104, the screw 101 can be rotated in one direction continuously. This continuous rotation increases the smoothness of the screw 101's rotation, thereby accelerating its rotation and reducing the resistance when clamping the I-beam.

[0021] like Figures 1 to 4 As shown, the mounting assembly 102 includes a mounting ring 2; the mounting ring 2 and the screw 101 are in a sliding fit; both the mounting ring 2 and the screw 101 are threaded with bolts 21; during operation, when the handle 104 needs to be disassembled, the bolts 21 can be rotated, causing the bolts 21 to gradually leave the screw 101 and the mounting ring 2. After the bolts 21 leave, the mounting ring 2 can be slid out from the end of the screw 101, and the handle 104 will be removed along with the mounting ring 2; by using the bolts 21 to connect the mounting ring 2 and the screw 101, the connection can be quickly fixed by threaded engagement, thereby increasing the convenience of disassembling and repairing the handle 104.

[0022] like Figures 3 to 5As shown, a ratchet 3 is fixedly connected to the end of the screw 101 on the first gripper 18; the ratchet 3 is located at the end near the first gripper 18; a pawl 31 is rotatably connected to the middle of the fixing rod 105 on the first gripper 18; the pawl 31 is connected to the fixing rod 105 by a torsion spring; during operation, when the screw 101 is rotated to bring the first gripper 18 and the second gripper 19 closer together, the screw 101 will drive the ratchet 3 to rotate. During rotation, the ratchet 3 will not be blocked by the pawl 31, at which time the pawl 31 will be on the ratchet. When the screw 101 rotates, it will continue to push, and after pushing, it will return to its original position due to the force of the torsion spring. When the screw 101 reverses, the pawl 31 will block the ratchet 3, preventing the ratchet 3 from rotating. When it is necessary to separate the first pawl 18 and the second pawl 19, the pawl 31 can be lifted to reverse the screw 101. By adding the ratchet 3 and the pawl 31, the screw 101 can be blocked after it rotates. Thus, when the screw 101 reverses after being fixed, the ratchet 3 is blocked by the pawl 31, thereby increasing the stability of the screw 101.

[0023] like Figures 3 to 4 As shown, the end of the handle 104 is provided with an identification groove 4; the identification groove 4 and the handle 104 are correspondingly arranged; during operation, when rotating the screw 101, the identification groove 4 can be observed, and the direction pointed to by the identification groove 4 is the direction in which the first gripper 18 and the second gripper 19 are connected, thereby increasing the reference point; by adding the identification groove 4, when rotating the screw 101, it is possible to quickly determine which direction is the connection between the first gripper 18 and the second gripper 19.

[0024] like Figures 3 to 4 As shown, a sponge strip 5 is fixed to the side wall of the handle 104; multiple sponge strips 5 are provided on the handle 104; during operation, when the handle 104 is gripped, it will first come into contact with the sponge strip 5, and the sponge strip 5 will be squeezed during contact, which will increase the contact area between the hand and the handle 104; by adding sponge strips 5, the contact area can be increased by the deformation of the sponge strips 5 when gripping the handle 104, thereby increasing the friction during contact and reducing slippage when the handle 104 is rotated.

[0025] like Figures 3 to 4 As shown, a ring 6 is fixed to the top of the bolt 21; the ring 6 and the bolt 21 are correspondingly arranged; during operation, when the bolt 21 is rotated, it can contact the ring 6. After contact, when the bolt 21 is rotated, the bolt 21 will be pushed through multiple force points of the ring 6; by adding the ring 6, the force-bearing area can be increased when the bolt 21 rotates, thereby reducing the rotational resistance and accelerating the rotation speed of the bolt 21.

[0026] Working principle: In operation, the servo motor 14 first controls the winding reel 15 to rotate, releasing the hoisting rope 16. This lowers the first gripper 18 and the second gripper 19. During descent, the first gripper 18 and the second gripper 19 are placed on the side of the I-beam. Then, the handle 104 is held and rotated. Rotation of the handle 104 drives the screw 101 to rotate via the rocker arm 103. The rotation of the screw 101 pushes the second gripper 19 closer to the first gripper 18. Once they are close, the first gripper 18 and the second gripper... The second gripper 19 gradually clamps the I-beam, thus connecting with it. Once connected, the adjusting arm 12 is activated via the drive assembly 11 to hoist the I-beam. After prolonged use, the handle 104 can be disassembled via the mounting assembly 102. To disassemble the handle 104, the bolt 21 can be rotated, causing it to gradually move away from the screw 101 and the mounting ring 2. Once the bolt 21 is removed, the mounting ring 2 can be slid out from the end of the screw 101. During removal, the handle 104 will follow. Remove the mounting ring 2 together; when the screw 101 is rotated and the first pawl 18 and the second pawl 19 are brought close together, the screw 101 will drive the ratchet 3 to rotate. When rotating, the ratchet 3 will not be blocked by the pawl 31. At this time, the pawl 31 will continue to push when the ratchet 3 rotates. After pushing, it will return to its original position due to the force of the torsion spring. When the screw 101 reverses, the pawl 31 will block the ratchet 3, making the ratchet 3 unable to rotate. When it is necessary to separate the first pawl 18 and the second pawl 19, the pawl 31 can be lifted to reverse the screw 101. When rotating the screw 101, the marking groove 4 can be observed. The direction pointed to by the marking groove 4 is the merging of the first gripper 18 and the second gripper 19, thereby increasing the reference point. When holding the handle 104, it will first come into contact with the sponge strip 5. When in contact, the sponge strip 5 will be squeezed, which will increase the contact area between the hand and the handle 104. When rotating the bolt 21, it will come into contact with the ring 6. After contact, when the bolt 21 is rotated, the bolt 21 will be pushed through multiple force points of the ring 6.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
