Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hoist, especially to a hoist boom support transport frame. BACKGROUND

[0002] In the hoist and other hoisting machinery, the boom as an important load-bearing component in the hoist plays a crucial role in the working process of the hoist. Usually, the boom of the truck crane is installed on the rotary table, and the rotary table is installed on the chassis. The chassis frame also has a boom support for supporting the boom. When the hoist is not working, the boom is placed on the boom support at a certain boom angle, so that the stability of the boom can be ensured during the hoist driving and parking process. The existing boom support is composed of two symmetrical support rods and connected by welding, and a mounting pad is arranged at the bottom of the support rod (as shown in the prior art CN202221894252.X). When transporting the boom support, the boom support is usually arranged vertically to prevent displacement during transportation on the transport vehicle. However, when encountering bumps or sudden braking, displacement may occur, resulting in mutual abrasion of the products.

[0003] The prior art CN202020867590.9 discloses a hoist boom support convenient to transport, which comprises two horizontally opposite support bodies, each support body comprising two horizontally opposite support rods, a connecting rod vertically penetrating between the two support rods, a plurality of openings provided on the support rods for the connecting rod to penetrate, a stop block fixedly connected to each end of the connecting rod, a through groove provided on the inner wall of the opening for the stop block to penetrate, and a limiting assembly provided on the outer side of the stop block for limiting the support rod from separating from the connecting rod. Although the structure of the boom support is changed to prevent damage during transportation, the following problems still exist:

[0004] 1. The boom support changes the structure of the boom support to facilitate transportation, but the present application focuses on the transport frame specially designed for transporting these supports. Therefore, the existing solution does not directly solve the problem of how to more safely and effectively fix and protect the boom support during transportation.

[0005] 2. Although the improvement proposed in the prior art CN202020867590.9 improves the stability of the boom support during transportation, it increases the connecting rod, stop block and limiting assembly, which not only makes the overall structure more complex, but also increases the manufacturing cost.

[0006] 3. The existing solution usually does not specially consider the convenience of loading and unloading the boom support. When multiple boom supports need to be loaded or unloaded onto the transport tool, the complex and fixed installation method may significantly reduce the work efficiency and increase the risk of manual operation.
