[0026] The embodiment of the present application provides a hanging ear device, see Figure 1 , Figure 2 and Figure 3 , including a first clamping component 100 arranged on the left side of the I-beam 600 and a second clamping component 200 arranged on the right side of the I-beam 600, the first clamping component 100 includes a first supporting portion 110 parallel to the web of the I-beam 600 and a first clamping portion 120 for fixing the lower wing plate of the I-beam 600, the second clamping component 200 includes a second supporting portion 210 parallel to the web of the I-beam 600 and a second clamping portion 220 for fixing the lower wing plate of the I-beam 600, the first clamping portion 120 and the second clamping portion 220 are detachably connected, the top of the first supporting portion 110 and the top of the second supporting portion 210 are detachably connected, and an installation component 500 is provided between the first supporting portion 110 and the second supporting portion 210.

[0027] The ear device uses a detachably connected first clamping part 120 and a second clamping part 220 and a detachably connected first support part 110 and a second support part 210, so that the first clamping component 100 and the second clamping component 200 can select a suitable position along the length direction of the I-beam 600 to clamp the I-beam 600, thereby realizing flexible sliding positioning.

It can be circulated multiple times, has a high utilization rate, and has high construction efficiency, and can be used for the installation of upper pull rod type cantilever I-beam scaffolding.

[0028] See also Figure 1 The first clamping portion 120 includes a third supporting portion 121 and a first connecting portion 122. The third supporting portion 121 is close to the lower wing plate of the I-beam 600. The left end of the third supporting portion 121 is connected to the bottom end of the first supporting portion 110. The top end of the first connecting portion 122 is connected to the right end of the third supporting portion 121. The second clamping portion 220 includes a fourth supporting portion 221 and a second connecting portion 222. The fourth supporting portion 221 is close to the lower wing plate of the I-beam 600. The right end of the fourth supporting portion 221 is connected to the bottom end of the second supporting portion 210. The top end of the second connecting portion 222 is connected to the left end of the fourth supporting portion 221. The first connecting portion 122 and the second connecting portion 222 are detachably connected.

[0029] It is understandable that the first clamping member 100 is a shaped and bent steel splint, that is, the first support portion 110, the third support portion 121 and the first connection portion 122 are of an integral structure; the second clamping member 200 is also a shaped and bent steel splint, that is, the second support portion 210, the fourth support portion 221 and the second connection portion 222 are of an integral structure. The first clamping member 100 and the second clamping member 200 are respectively located on the left and right sides of the I-beam 600 to form a U-shaped structure, improving the overall stability of the lifting lug device.

[0030] In some embodiments, the third support portion 121 and the first connection portion 122 are vertically arranged, the fourth support portion 221 and the second connection portion 222 are vertically arranged, and both the first clamping portion 120 and the second clamping portion 220 are L-shaped, making the overall structure of the lifting lug device more stable. Moreover, the L-shaped structure is convenient for assembly, installation and disassembly, facilitating factory prefabrication, with simpler assembly, easier operation, and being more acceptable to the installation and disassembly construction personnel, thus ensuring the installation quality.

[0031] See Figure 1 , the first connection portion 122 and the second connection portion 222 are detachably connected by a first bolt 300. The first bolt 300 is used to tightly fix the lifting lug device at the required position on the I-beam 600. The connection between the first connection portion 122 and the second connection portion 222 by the first bolt 300 is convenient for disassembly and maintenance when needed, has a certain error tolerance, can be suitable for I-beams of different lengths or models during on-site construction, can be used multiple times, reduces costs, can evenly transfer loads, and improves the reliability of the connection.

[0032] See Figure 2 , the first support portion 110 and the second support portion 210 are detachably connected by a second bolt 400. The second bolt 400 is provided on the top of the upper flange of the I-beam 600 and is closely attached to the upper flange of the I-beam 600. The use of the second bolt 400 for detachable connection makes the installation and disassembly process more flexible, not restricted by on-site conditions, and the cost is relatively economical.

[0033] See Figure 2 , there are multiple second bolts 400. The multiple second bolts 400 are arranged along the length direction of the I-beam 600. The multiple second bolts 400 can clamp the I-beam to prevent sliding. In the embodiments of Figure 2 and Figure 3 , there are two second bolts 400, ensuring the overall stability of the lifting lug structure.

[0034] The installation component 500 includes a pin shaft 510 for connecting the steel tie rod. Pin holes are provided at the tops of the first support portion 110 and the second support portion 210. The pin shaft 510 passes through the pin holes to connect with the first support portion 110 and the second support portion 210. The pin shaft 510 is located above the second bolt 400. The installation process of the pin shaft 510 is relatively simple, saving time and labor; it can bear a large load, allowing relative rotation between the connecting components, having good flexibility. During use, the pin shaft 510 passes through the loop hole at the end of the steel tie rod 700 and is then installed on the first support portion 110 and the second support portion 210. It is relatively convenient to install and remove the pin shaft.

[0035] The installation component 500 includes a pin ring 520. A positioning hole for inserting the pin ring 520 is provided at the end of the pin shaft 510. After the pin shaft 510 and the steel tie rod 700 are installed, the pin ring 520 is inserted into the positioning hole, which can prevent the pin shaft 510 from falling off, providing a stable and reliable connection. The pin shaft 510 can bear a large load, is suitable for occasions where torque needs to be transmitted, has convenient connection, is easy to assemble and disassemble, and makes the structure of the lifting lug device compact, does not occupy too much space, and is easy to replace and maintain. Using the positioning hole to install the pin ring 520 is convenient for installation and disassembly, and the construction is convenient.

[0036] In some embodiments, the pin shaft 510 is arranged in parallel with the second bolt 400. The pin shaft 510 is located between two adjacent second bolts 400, and the first bolt 300 is located between two adjacent second bolts 400, making the overall structure of the lifting lug device more stable.

[0037] Both the first support portion 110 and the second support portion 210 are made of steel splints. Specifically, shaped steel splints with a thickness of 10 mm are used, which can be customized according to different models of I-beams in the factory, and can be applicable to different models of I-beams. The steel splints have high strength and rigidity, long service life, can bear large loads and stresses, and can maintain the stability of the structure during use, are easy to install and connect, can improve construction efficiency, can be disassembled and reused, have good fire resistance, can increase the safety of buildings, have strong environmental adaptability, are not easily corroded, have good economy, relatively low cost, and high comprehensive cost performance.

[0038] The installation method of this lifting lug device is as follows:

[0039] Step 1: When in use, select the shaped steel splints corresponding to the I-beam model, put the first clamping component 100 and the second clamping component 200 on the I-beam, move along the I-beam to the appropriate position, and first install and tighten the lower first bolt 300;

[0040] Step 2: Then, two second bolts 400 are installed on the tops of the first clamping member 100 and the second clamping member 200, and the second bolts 400 are tightened to tightly clamp the I-beam 600 with the first clamping member 100 and the second clamping member 200;

[0041] Step 3: Next, the pin shaft 510 is passed through the ring hole at the end of the steel tie rod 700, then inserted into the upper pin hole, and a pin ring 520 is inserted on the pin shaft 510 to prevent it from falling off, and the upper bolt is tightened for fixation.

[0042] This lifting lug device can be designed according to the different lengths of the steel tie rod 700, and can be moved, positioned and fixed on the I-beam 600. Moreover, the first clamping member 100 and the second clamping member 200 of this application are factory-customized components with high quality controllability, which helps to improve the safety of the upper tie-rod type cantilever scaffolding. In addition, compared with the traditional lifting lug, the lifting lug position of this application can be adjusted, and can be flexibly adjusted according to the actual situation on site. It has a wider applicability and a higher number of reusable times. The first clamping member 100 and the second clamping member 200 are combined, and the assembly is more convenient, the operation is easy, and the installation and disassembly construction personnel are more receptive, thus ensuring the installation quality.
