Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a sling fork lifting and mounting support arm. Background Technology

[0002] With the rapid development of industries such as bridge and heavy equipment manufacturing, the hoisting and installation of large components is increasing. During the hoisting process, the accurate connection and installation of the sling forks and arch rib lugs is a key step in ensuring hoisting safety and construction quality.

[0003] In the existing technology, the boom structure is difficult to adjust the pitch angle of the fork lugs flexibly. When the position of the arch rib lifting lugs is irregular or there is an installation angle deviation, the fork lugs cannot be inserted vertically into the arch rib lifting lugs. It is often necessary to repeatedly adjust the position and angle of the lifting equipment, which not only consumes a lot of time and manpower, but also easily causes errors due to multiple adjustments, resulting in insufficient installation accuracy. Therefore, improvements are needed. Utility Model Content

[0004] This utility model mainly provides a lifting and mounting bracket for a hoisting equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting and mounting support arm for sling forks, comprising a square tube steel support arm, a connecting flange fixedly installed at one end of the square tube steel support arm, a flange hole through the surface of the connecting flange, a U-shaped plate fixedly installed at the other end of the square tube steel support arm, an elevation swing bracket provided on the inner side of the U-shaped plate, an elevation swing bearing fixedly installed inside the U-shaped plate, an elevation swing shaft fixedly connected to the surface of the elevation swing bracket, an elevation swing shaft hole opened on the side of the U-shaped plate, a locking pin provided inside the elevation swing bracket, and a pin hole through the surface of the elevation swing bracket.

[0006] Preferably, the pitch swing pivot is rotatably connected to the pitch swing pivot hole. This design allows the pitch swing bracket to rotate freely around the pitch swing pivot within a certain angle range, thereby enabling flexible adjustment of the pitch angle of the fork lug during lifting.

[0007] Preferably, the elevation swing shaft rotates between the elevation swing bearing and the elevation swing pivot. There are two sets of elevation swing bearings and elevation swing shafts. By setting two sets of elevation swing bearings and elevation swing pivots, the elevation swing bracket can be supported more stably, making it more stable during rotation and reducing shaking and deviation.

[0008] Preferably, the locking pin and the pin hole are connected by an interference fit. This interference fit connection effectively prevents the tilting bracket from rotating unexpectedly due to external forces during hoisting, ensuring that the angle of the fork lug remains stable during installation.

[0009] Preferably, the inner side of the tilting bracket is provided with anti-slip texture. The anti-slip texture is distributed in a circumferential shape on the inner side of the tilting bracket. The anti-slip texture can increase the friction between the fork lug and the bracket, prevent the fork lug from sliding in the bracket, and further improve the stability and reliability of the fork lug during the lifting and installation process, ensuring the smooth progress of the hoisting operation.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by installing components such as a U-shaped plate, an elevation swing bracket, an elevation swing bearing, and a rotating shaft, the elevation swing rotating shaft cooperates with the elevation swing bearing and the shaft hole, allowing the elevation swing bracket to rotate freely. This enables free adjustment of the pitch angle of the fork lug during lifting, allowing for precise adjustment of the fork lug angle, solving the problem that the fork lug cannot be vertically inserted into the arch rib lifting lug, ensuring that the fork lug is smoothly installed in place, and improving construction efficiency.

[0012] 2. In this utility model, the anti-slip texture distributed in a circular pattern on the inner side of the tilting bracket increases the friction between the bracket and the fork lug, further preventing the fork lug from sliding and ensuring the stability and safety of the installation operation.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a lifting and mounting support arm for a sling fork, including a square tube steel support arm 1. A connecting flange 2 is fixedly installed at one end of the square tube steel support arm 1. A flange hole 3 is opened through the surface of the connecting flange 2. A U-shaped plate 4 is fixedly installed at the other end of the square tube steel support arm 1. An elevation swing bracket 5 is provided on the inner side of the U-shaped plate 4. An elevation swing bearing 6 is fixedly installed inside the U-shaped plate 4. An elevation swing shaft 7 is fixedly connected to the surface of the elevation swing bracket 5. An elevation swing shaft hole 8 is opened on the side of the U-shaped plate 4. A locking pin 9 is provided inside the elevation swing bracket 5. A pin hole 10 is opened through the surface of the elevation swing bracket 5.

[0021] like Figure 4 As shown, the tilt angle swing shaft 7 is rotatably connected to the tilt angle swing shaft hole 8. This design allows the tilt angle swing bracket 5 to rotate freely around the tilt angle swing shaft 7 within a certain angle range, thereby enabling flexible adjustment of the tilt angle of the fork lug during the lifting process.

[0022] like Figure 4 As shown, the pitch swing shaft 7 rotates between the pitch swing bearing 6 and the pitch swing bearing 6. There are two sets of pitch swing bearing 6 and pitch swing shaft 7. By setting two sets of pitch swing bearing 6 and pitch swing shaft 7, the pitch swing bracket 5 can be supported more stably, making it more stable during rotation and reducing shaking and deviation.

[0023] like Figure 4 As shown, the locking pin 9 and the pin hole 10 are connected by an interference fit. This interference fit connection effectively prevents the tilting bracket 5 from rotating unexpectedly due to external forces during hoisting, ensuring that the angle of the fork lug remains stable during installation.

[0024] like Figure 4As shown, anti-slip texture 11 is provided on the inner side of the tilting bracket 5. The anti-slip texture 11 is distributed in a circumferential shape on the inner side of the tilting bracket 5. The anti-slip texture 11 can increase the friction between the fork lug and the bracket, prevent the fork lug from sliding in the bracket, and further improve the stability and reliability of the fork lug during the lifting and installation process, ensuring the smooth progress of the hoisting operation.

[0025] The usage and working principle of this device are as follows: When using this sling fork lug to lift and install the outrigger, first connect the outrigger to the lifting equipment using bolts through the flange hole 3 on the flange 2 at one end of the square tube steel outrigger 1. Next, place the sling fork lug inside the tilting bracket 5. Because the tilting bracket 5 has circumferentially distributed anti-slip texture 11 on its inner side, it increases the friction between the sling lug and the fork lug, preventing slippage. Then, according to the position and angle of the arch rib lifting lug, manually adjust the tilting bracket 5 using the rotational connection between the tilting swing shaft 7, the tilting swing bearing 6, and the tilting swing shaft hole 8, thereby changing the tilt angle of the fork lug. During this process... Two sets of tilting bearings 6 and tilting pivots 7 stably support the tilting bracket 5, reducing swaying and deviation during rotation. After the fork lug angle is adjusted to match the arch rib lifting lug, the locking pin 9 is inserted into the pin hole 10 on the surface of the tilting bracket 5. The locking pin 9 and the pin hole 10 are used to lock the position of the tilting bracket 5 by the tightness generated by the interference fit, preventing it from rotating accidentally due to external force during hoisting. Then, the hoisting equipment is started, and the hoisting equipment drives the boom to lift the fork lug to a suitable height. During the lifting process, the boom ensures that the fork lug rises smoothly by virtue of its own structure and connection stability. Finally, the fork lug is accurately inserted into the arch rib lifting lug, completing the installation operation.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
