It aims to ensure processing accuracy, improve efficiency, and adapt to the operational needs of channel steel of different specifications. It typically consists of billet clamps, a spiral shaft, and lifting rings. However, when using existing unloading and conveying fixtures, the fixture needs to be held by manually turning the spiral shaft. The fixture itself is quite heavy, and turning the spiral shaft requires a lot of force, making it inconvenient for holding. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a channel steel unloading and conveying clamp, comprising:

[0006] The device body includes an I-beam clamp, the surface of which is provided with lifting rings;

[0007] An automatic clamping mechanism includes a protective box that acts on the surface of an I-beam clamp. A drive motor is installed inside the protective box. A connecting threaded rod is rotatably connected to the surface of the drive motor. A connecting block is threadedly fitted onto the surface of the connecting threaded rod. A first hinge rod is hinged to the surface of the connecting block. A second hinge rod is hinged to the end of the first hinge rod away from the connecting block. A first fixed shaft is fixedly connected inside the protective box. A second fixed shaft is fixedly connected inside the protective box.

The first fixed shaft is symmetrically distributed in two groups inside the protective box, and the second hinge rod is rotatably connected to the surface of the first hinge rod and the first fixed shaft.

[0010] Preferably, the two ends of the second hinge are hinged to the surfaces of the I-beam clamp and the first hinge, and the I-beam clamp is movably connected to the surface of the protective box through the second hinge.

[0011] Preferably, the second fixed shafts are symmetrically distributed in two sets inside the protective box, and the two ends of the third hinge rod are hinged to the surfaces of the second fixed shafts and the I-beam clamp.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By connecting the protective box and the drive motor, and the drive motor and the connecting threaded rod, the drive motor can be started to drive the connecting threaded rod to rotate. Then, by connecting the connecting threaded rod and the connecting block, and the connecting block and the first hinge rod, the connecting block can move on the surface of the connecting threaded rod, thereby driving the first hinge rods on both sides to rotate.

[0017] 2. By connecting the handle and the limiting rod, and the mounting slot and the limiting rod, the movable handle allows the limiting rod to leave the mounting slot, enabling the lifting ring to be installed in the mounting slot. The damping spring follows the deformation. Then, by connecting the protective box and the mounting slot, and the lifting ring and the mounting slot, the lifting ring can be installed in the mounting slot. Then, by connecting the limiting rod and the damping spring, and the lifting ring and the limiting rod, the damping spring returns to its original shape, causing the limiting rod to reset and insert into the lifting ring, thus fixing the installation position of the lifting ring. Conversely, the lifting ring can be disassembled and replaced, achieving the effect of convenient lifting ring replacement. Attached Figure Description

[0024] 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 protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A channel steel unloading and conveying clamp includes:

[0027] The device body includes an I-beam clamp 1, and a lifting ring 11 is provided on the surface of the I-beam clamp 1. Both the I-beam clamp 1 and the lifting ring 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.

[0028] An automatic clamping mechanism includes a protective box 2, which acts on the surface of the I-beam clamp 1 to protect its internal structure. Inside the protective box 2 is a drive motor 21 that drives a connecting threaded rod 22 to rotate. The surface of the drive motor 21 is rotatably connected to the connecting threaded rod 22, which, through its own rotation, moves the connecting block 23. The surface of the connecting threaded rod 22 is threadedly fitted with the connecting block 23, connecting a first hinge rod 24. The surface of the connecting block 23 is hinged to the first hinge rod 24, connecting the connecting block 23 and a second hinge rod 25. The end of the first hinge rod 24 furthest from the connecting block 23 is hinged to the second hinge rod 25, connecting the first hinge rod 24 and the I-beam clamp 1. Inside the protective box 2 is a fixedly connected first fixed shaft 26, connecting the second hinge rod 25. Inside the protective box 2 is a fixedly connected second fixed shaft 27, connecting a third hinge rod 28. The surface of the second fixed shaft 27 is hinged to the third hinge rod 28 to prevent the I-beam clamp 1 from rotating.

[0029] Furthermore, the connecting threaded rod 22 is rotatably connected to the inside of the protective box 2 via the drive motor 21, and the connecting block 23 is movably connected to the inside of the protective box 2 via the connecting threaded rod 22. When the drive motor 21 is started, it drives the connecting threaded rod 22 to rotate, thereby causing the connecting block 23 to move.

[0030] Furthermore, the first hinge rods 24 are symmetrically distributed in two sets on the surface of the connecting block 23. The first hinge rods 24 are rotatably connected to the inside of the protective box 2 through the connecting block 23. The first fixed shafts 26 are symmetrically distributed in two sets inside the protective box 2. The second hinge rods 25 are rotatably connected to the surfaces of the first hinge rods 24 and the first fixed shafts 26. The movement of the connecting block 23 drives the first hinge rods 24 on both sides to rotate synchronously, thereby causing the two sets of second hinge rods 25 to rotate on the surface of the first fixed shafts 26.

[0031] Furthermore, the two ends of the second hinge rod 25 are hinged to the surfaces of the I-beam clamp 1 and the first hinge rod 24. The I-beam clamp 1 is movably connected to the surface of the protective box 2 through the second hinge rod 25. The two sets of I-beam clamps 1 move towards each other as the second hinge rod 25 rotates.

[0032] Furthermore, the second fixed shafts 27 are symmetrically distributed in two sets inside the protective box 2. The two ends of the third hinge rod 28 are hinged to the surfaces of the second fixed shafts 27 and the I-beam clamp 1. The third hinge rod 28 is rotatably connected to the surfaces of the I-beam clamp 1 and the second fixed shaft 27. The movement of the I-beam clamp 1 drives the third hinge rod 28 to rotate on the surface of the second fixed shaft 27, thereby making the I-beam clamp 1 move linearly without rotating, so that the two sets of I-beam clamps 1 are clamped on the surface of the channel steel.

[0033] Furthermore, the disassembly and replacement mechanism includes a mounting groove 3, which is formed on the surface of the protective box 2 for inserting and installing the lifting ring 11. A connecting cylinder 31 is fixedly connected to the surface of the protective box 2 for connecting the limiting rod 33. A handle 32 is movably connected to the surface of the connecting cylinder 31 for moving the limiting rod 33. The limiting rod 33 is fixedly connected to the surface of the handle 32 for inserting into the surface of the lifting ring 11. A damping spring 34 is wound around the surface of the limiting rod 33 for inserting into the surface of the lifting ring 11 through its own deformation.

[0034] Furthermore, the mounting slots 3 are symmetrically arranged in two sets on the surface of the protective box 2. The limiting rod 33 is movably connected to the inside of the mounting slot 3 via the pull handle 32. The lifting ring 11 is connected to the surface of the protective box 2 via the mounting slot 3. Pulling the pull handle 32 causes the limiting rod 33 to leave the inside of the mounting slot 3, allowing the lifting ring 11 to be inserted into the inside of the mounting slot 3. The damping spring 34 deforms accordingly, inserting the lifting ring 11 into the mounting slot 3.

[0035] Furthermore, the two ends of the damping spring 34 are fixedly connected to the inside of the connecting cylinder 31 and the surface of the limiting rod 33. The limiting rod 33 is movably connected to the inside of the connecting cylinder 31 through the damping spring 34. The surface of the lifting ring 11 has a slot. The limiting rod 33 is inserted into the surface of the lifting ring 11 through the damping spring 34. When the restriction on the pull handle 32 is released, the damping spring 34 drives the limiting rod 33 to reset and insert into the slot on the surface of the lifting ring 11 in order to restore its original state, thereby restricting the installation position of the lifting ring 11. The elasticity of the damping spring 34 itself matches the installation mechanism in this application, and the limiting rod 33 will not be dislodged from the surface of the lifting ring 11 due to vibration when suspending and conveying the channel steel.

[0036] Working principle: When using the I-beam clamp 1, first pull the handle 32 to disengage the limiting rod 33 from the mounting groove 3, allowing the lifting ring 11 to be inserted into the mounting groove 3. The damping spring 34 deforms accordingly, inserting the lifting ring 11 into the mounting groove 3. Release the handle 32, and the damping spring 34 returns to its original shape, causing the limiting rod 33 to reset and insert into the slot on the surface of the lifting ring 11, thus limiting the installation position of the lifting ring 11. Place the two sets of I-beam clamps 1 on both sides of the channel steel, and then start the drive motor. 21 drives the connecting threaded rod 22 to rotate, thereby causing the connecting block 23 to move. The movement of the connecting block 23 causes the first hinge rods 24 on both sides to rotate synchronously, thereby causing the two sets of second hinge rods 25 to rotate on the surface of the first fixed shaft 26. The two sets of I-beam clamps 1 move towards each other following the rotation of the second hinge rods 25. The movement of the I-beam clamps 1 causes the third hinge rod 28 to rotate on the surface of the second fixed shaft 27, thereby causing the I-beam clamps 1 to move linearly without rotating, so that the two sets of I-beam clamps 1 are clamped on the surface of the channel steel.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
