Description

Technical Field

[0001] This application relates to the technical field of H-beam lifting devices, and in particular to a self-locking clamp type H-beam lifting device. Background Technology

[0002] H-beams are steel structures with an "H"-shaped cross-section. They have a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio, and are often used for steel structure support in buildings.

[0003] When hoisting H-beams on construction sites, specialized hoisting equipment is often used to clamp and secure the top flanges of the H-beams. Common H-beam hoisting equipment requires manual placement on top of the H-beam and manual tightening to the top flanges. While this method ensures stability and safety, it requires manual operation for each loading and unloading, resulting in low efficiency in H-beam transportation. Utility Model Content

[0004] The purpose of this utility model application is to improve the low efficiency of H-beam hoisting devices in transferring H-beams. This application provides a self-locking clamp type H-beam hoisting device.

[0005] The self-locking clamp type H-beam hoisting device provided in this application adopts the following technical solution:

[0006] A self-locking clamp type H-beam hoisting device, comprising:

[0007] The clamping frame is set in pairs, at least two pairs, and the side wall has a slot, into which the edge of the H-beam can extend.

[0008] The lifting rod is rotatably connected to one end of the top of the clamping frame facing the middle of the H-beam, and the other ends of the lifting rods of the two opposing clamping frames are rotatably connected to each other;

[0009] The connecting beam has one end of the two lifting rods rotatably connected to each other and is rotatably connected inside the connecting beam. The crane's slings are connected to the connecting beam and keep the connecting beam in a horizontal state when it is lifted.

[0010] Optionally, a locking cavity is provided at the top of the clamping frame, and a locking arc plate is rotatably connected inside the locking cavity. The part of the lifting rod that is rotatably connected to the clamping frame is a cam and is located inside the locking cavity. The rotating shaft of the locking arc plate is equipped with a torsion spring, so that the locking arc plate and the cam are pressed together. When the connecting beam is lifted, the rotation of the lifting rod can make the locking arc plate press against the top of the H-beam.

[0011] Optionally, the bottom of the locking arc plate has serrated edges.

[0012] Optionally, the bottom wall of the slot has serrated edges.

[0013] Optionally, a safety rope is connected to the top of the clamping frame and is connected to the crane, but is not in a stretched state. In summary, this application includes at least one of the following beneficial technical effects:

[0014] Place the clamping frames on the side wings of the H-beam and make the side wings fit into the slots. Lift the connecting beam, and the connecting beam will pull the two opposing clamping frames together through the lifting rod, thereby achieving self-locking during hoisting. This will make the two opposing clamping frames clamp the H-beam, improving the efficiency and safety of H-beam transportation.

[0015] During the rotation of the lifting rod, the cam presses down the locking arc plate, causing the locking arc plate to press against the upper surface of the H-beam, thereby improving the stability of the clamping frame in clamping and fixing the H-beam. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses a self-locking clamp type H-beam hoisting device.

[0021] refer to Figure 1 and Figure 2 The self-locking clamp type H-beam hoisting device includes a clamping frame 1, a lifting rod 2, and a connecting beam 3.

[0022] The clamping frames 1 are arranged in pairs, at least two pairs; in this embodiment, there are two pairs. The side walls of the clamping frames 1 have slots 11 with a "C"-shaped cross-section. The edges of the H-beams can extend into the slots 11. Lifting rods 2 are rotatably connected to the top of the clamping frames 1 facing the middle of the H-beams, and the other ends of the lifting rods 2 of the two opposing clamping frames 1 are rotatably connected to each other. The ends of the two lifting rods 2 that are rotatably connected to each other are rotatably connected to the connecting beam 3. In this embodiment, the two sets of lifting rods 2 are located at both ends of the connecting beam 3. The crane's slings are connected to the connecting beam 3 and keep the connecting beam 3 horizontal during lifting.

[0023] A locking cavity 12 is provided at the top of the clamping frame 1, and a locking arc plate 4 is rotatably connected inside the locking cavity 12. The lifting rod 2 is rotatably connected to the clamping frame 1 by a cam 21, which is located inside the locking cavity 12. A torsion spring is provided on the rotating shaft of the locking arc plate 4, so that the locking arc plate 4 abuts against the cam 21. When the connecting beam 3 is lifted, the rotation of the lifting rod 2 can make the locking arc plate 4 abut against the top of the H-beam. The bottom of the locking arc plate 4 and the bottom wall of the slot 11 are both covered with teeth. A safety rope is connected to the top of the clamping frame 1, and the safety rope is connected to the crane and is not in a stretched state.

[0024] The clamping frame 1 is secured to the top edge of the H-beam. Then, the connecting beam 3 is lifted by a crane. As the lifting rod 2 rotates, it not only pulls the two clamping frames 1 together, but also, during rotation, the cam 21 presses the locking arc plate 4 downwards, causing it to press against the upper surface of the H-beam, thus achieving self-locking and improving the stability of the H-beam fastening. The serrations on the inner bottom wall of the locking arc plate 4 and the groove 11 effectively increase the friction with the H-beam surface, further enhancing the stability of the fastening. The safety rope provides additional safety for the hoisting and transport of the H-beam.

[0025] The implementation principle of the self-locking clamp type H-beam hoisting device in this application embodiment is as follows: After the clamping frame 1 is clamped on the top edge of the H-beam, during the hoisting of the connecting beam 3 by the crane, the lifting rod 2 not only pulls the clamping frames 1 on both sides together, but also makes the locking arc plate 4 press against the upper surface of the H-beam by rotating the lifting rod 2, thereby realizing the self-locking of the clamping frame 1 and the H-beam, improving the stability and safety of the H-beam hoisting and transportation process, and also improving the efficiency of H-beam transportation.

[0026] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
