Description

Technical Field

[0001] The utility model relates to the technical field of steel material handling tools, in particular to a convenient I-beam clamp. Background Art

[0002] I-beam is also called steel beam (English name: Universal Beam), which is a long steel bar with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is a steel section with an I-shaped cross section. I-beams mainly include horizontally arranged upper wing plates and lower wing plates, and vertically arranged waist plates connecting the upper wing plates and the lower wing plates.

[0003] In tunnel construction, I-beams are one of the most commonly used steel materials. During the transportation process, I-beams are mostly transported to the installation location manually. However, due to the heavy weight of I-beams and the traditional transportation method of using straps, the straps are prone to fatigue after repeated use, which may cause the straps to break during a certain use. The I-beams fall off during the transportation process, causing cost losses and even life safety issues. Therefore, there is an urgent need for a tool that can effectively transport I-beams. Utility Model Content

[0025] Example: See Figure 1 , Figure 2 and Figure 3 As shown, a convenient I-beam clamp of an embodiment is shown, which includes two clamp assemblies 1; a rotating shaft 2 connecting the two clamp assemblies 1; wherein the clamp assembly 1 includes: a first gripper 11 and a second gripper 12 which are cross-arranged and both take the rotating shaft 2 as the rotation center, the first gripper 11 and the second gripper 12 both have a gripper head 13 facing the I-beam 100, and a rotating positioning member 14 rotatably connected to the first gripper 11, when the gripper head 13 grips the upper wing plate of the I-beam 100, the rotating positioning member 14 rotates and connects to the second gripper 12, and the gripper heads 13 of the first gripper 11 and the second gripper 12 grip the I-beam 100.

[0026] In this embodiment, the first gripper 11 is in an S-shaped structure, and the second gripper 12 is in an inverted S-shaped structure. The first gripper 11 and the second gripper 12 are both provided with a through hole 18 in the middle for the rotation shaft 2 to pass through.

[0027] In this embodiment, the upper portion of the first gripper 11 is rotatably connected to the rotation positioning member 14 via a pin 17 , and the upper portion of the second gripper 12 has a groove portion 15 for accommodating the rotation positioning member 14 .

[0028] In this embodiment, the rotation positioning member 14 includes a rotation frame 141 connected to the first gripper 11 , a connecting rod 142 connected to the rotation frame 141 , and a positioning rod 143 disposed at an end of the connecting rod 142 away from the rotation frame 141 .

[0029] In this embodiment, a guide groove 151 for accommodating the connecting rod 142 is formed near the rotation positioning member 14 of the groove portion 15 , and a screw hole 161 is formed away from the rotation positioning member 14 , in which a positioning screw 16 is installed.

[0030] In this embodiment, after the connecting rod 142 of the rotating positioning member 14 enters the guide groove 151 , the positioning screw 16 approaches and abuts against the positioning rod 143 during the rotation process and fixes the relative positions of the first gripper 11 and the second gripper 12 .

[0031] In this embodiment, both ends of the rotating shaft 2 pass through and are exposed outside the clamp assembly 1, and are connected to the mounting sleeve 31 at the end. The top of the mounting sleeve 31 extends outward to form a protrusion 32, the protrusion 32 is connected to the lifting ring 33, and the lifting ring 33 is connected to the lifting rope 34.

[0032] The characteristics and functions of the present invention can be further understood through the following description.

[0033] Continue to see Figure 1 , Figure 2 and Figure 3 As shown, the handling fixture of this embodiment mainly solves the problem that some I-beams fall off during the handling process due to the heavy weight of the I-beams and the traditional handling method using straps. The straps are prone to fatigue after multiple uses, which may cause the straps to break during a certain use. This causes the I-beams to fall off during the handling process, resulting in cost losses and even life safety issues. In order to firmly clamp the I-beams during the handling process so that they are not easy to fall off, this embodiment proposes a convenient I-beam clamp, which mainly includes two clamp assemblies 1 arranged in the length direction of the I-beam 100, a rotating shaft 2 is connected between the two clamp assemblies 1, and the rotating shaft 2 exposes the external connection suspension member 3 of the clamp assembly 1. When the clamp assembly 1 clamps the I-beam 100, the external lifting equipment controls the lifting of the suspension member 3 to lift the I-beam 100 clamped by the two clamp assemblies 1 and carry it.

[0034] The clamp assembly 1 includes a first gripper 11 and two second grippers 12. The first gripper 11 is located between the two second grippers 12. The tops of the two second grippers 12 form a groove 15. The first gripper 11 and the second gripper 12 are cross-mounted in a scissor-like manner. A through hole 18 is provided at the intersection. The shaft passes through the through hole 18, so that the first gripper 11 and the second gripper 12 can rotate relative to the shaft 2 and move closer to or away from each other. The first gripper 11 and the second gripper 12 both have a gripper head 13. When the two gripper heads 13 are close to each other, they grip the upper wing plate of the I-beam 100.

[0035] The top of the first gripper 11 is also rotatably connected to the rotating positioning member 14 through a pin 17. One end of the rotating positioning member 14 docks with the groove portion 15 of the second gripper 12 during rotation. The second gripper 12 is also provided with a positioning screw 16, which presses the rotating positioning member 14 during rotation to fix the relative position between the first gripper 11 and the second gripper 12.

[0036] The working method of the convenient I-beam fixture of this embodiment is as follows:

[0037] like Figure 4As shown, the gripping heads 13 of the two clamp assemblies 1 are gripped on the upper wing plate of the I-beam 100. After the gripping heads 13 of each clamp assembly 1 grip the I-beam 100, the rotary positioning member 14 is rotated so that the positioning rod 143 of the rotary positioning member 14 enters the groove 15, and the positioning screw 16 is locked, so that the position between the first gripper 11 and the second gripper 12 is fixed and will not change. The lifting equipment lifts the two clamp assemblies 1 together with the I-beam 100 through the suspension member 3 and the rotating shaft 2 connecting the two clamp assemblies 1 and carries them.

[0038] In summary, the utility model arranges two clamp assemblies having a first gripper and a second gripper installed in a scissor-like cross-type in the length direction of the I-beam, and the gripping heads of the first gripper and the second gripper of the clamp assembly grip the upper wing plate of the I-beam, and rotate the positioning piece to the groove portion of the second gripper, and then rotate the positioning screw to lock the rotating positioning piece through the positioning screw to lock the relative position between the first gripper and the second gripper, thereby finally achieving the clamping of the I-beam by the clamp assembly, and lifting the rotating shaft connecting the two clamp assemblies through a lifting rope to achieve the transportation of the I-beam.

[0039] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
