Description

Technical Field

[0001] The utility model relates to the technical field of boom processing, in particular to a boom clamping tool. Background Art

[0002] In cranes and other lifting machinery, the boom, as an important load-bearing component in the crane, plays a vital role in the operation of the crane.

[0003] The development of offshore oil requires the use of truss marine cranes to assist in lifting work on offshore drilling platforms. The truss boom is an important component of the crane, and the length of the boom directly affects the radius of platform lifting. Therefore, due to the influence of length, the boom is often made in multiple sections, so each part of the boom needs to be welded.

[0004] A boom welding method is disclosed in a patent document with Chinese patent application number 2022112095.3.0 and publication date 2023.01.20, which includes the following specific steps: S1, fixing the flange on the flange tooling; S2, docking the flange tooling with the boom so that the flange is aligned with the four corners of the boom; S3, spot welding the flange to pre-fix the flange and the boom; S301, after spot welding one flange, spot welding the second flange on the diagonal of the flange to pre-fix it; S302, after spot welding the flange on one diagonal, spot welding the flange on the next diagonal is performed; S4, performing a bottom weld on the flange; S401, performing a bottom weld on the first spot-welded flange; S402, performing a bottom weld on the second flange on the diagonal of the first flange that has completed the bottom weld; S403, after completing the bottom weld on one diagonal flange, performing the bottom weld on the next diagonal flange; S5, fully welding the flanges in diagonal order; S6, after waiting for the temperature to cool down, removing the flange tooling.

[0005] The prior art of this document discloses a method for welding a boom. Since the boom is usually long and therefore heavy, the position of the boom needs to be changed according to different processes. During the process of transferring the boom, the welding between the booms may not be fully welded. In this way, if the boom is directly hoisted, the center of gravity of the boom will fall on the position where the boom is lifted by the hoisting platform, which may cause the boom to be deformed at the hoisting position due to its own weight, thereby affecting the subsequent full welding. Summary of the Invention

[0006] The utility model provides a boom clamping tool, which can clamp and fix the boom, so that if the position of the boom needs to be changed, the boom does not need to be directly hoisted, thereby ensuring that the boom is not easily deformed during the hoisting process.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a boom clamping tool for clamping the boom, comprising more than one boom bracket, the boom bracket being distributed along the length direction of the boom, the boom bracket comprising a first boom bracket and a second boom bracket, the cross-section of the first boom bracket and the second boom bracket being semi-circular, the first boom bracket and the second boom bracket being fitted together to form a boom bracket with an accommodating space in the center; a boom is placed in the accommodating space, the first boom bracket and the second boom bracket being close to each other and clamping the boom, and the inner side walls of the first boom bracket and the second boom bracket being provided with an inwardly recessed hoisting space.

[0008] The above structure forms an arm bracket with an accommodating space in the center by bringing the first arm bracket and the second arm bracket close to each other, so that when the arm is welded, the first arm bracket and the second arm bracket are clamped to the arm. Therefore, when the arm needs to be moved, the arm bracket is lifted by connecting the lifting platform with the lifting space, thereby realizing the transfer of the arm. The lifting platform is not directly connected to the arm, but moves the arm bracket, thereby ensuring that the arm is not easily deformed during the lifting process.

[0009] Furthermore, first inwardly recessed clamping plates are provided at both ends of the inner side wall of the first boom bracket, and second inwardly recessed clamping plates are provided at both ends of the inner side wall of the second boom bracket. The first clamping plates and the second clamping plates are provided to clamp the four corners of the boom.

[0010] The above arrangement is to provide a recessed first clamping plate and a second clamping plate at both ends of the first boom bracket and the second boom bracket, thereby forming a receiving space matched with the outer side wall of the boom through the first clamping plate and the second clamping plate, thereby ensuring the reliability of clamping.

[0011] Furthermore, one or more connecting holes are provided on the first clamping plate and the second clamping plate, and fixing components are provided in the connecting holes. The first boom bracket and the second boom bracket are brought close to each other through the fixing components and clamp the boom.

[0012] The above arrangement, by providing the connecting hole, facilitates the first boom bracket and the second boom bracket to approach each other and clamp the boom.

[0013] Furthermore, the fixing component is a fixing bolt.

[0014] The above arrangement fixes the first boom bracket and the second boom bracket by fixing bolts, and the structure is simple and reliable.

[0015] Furthermore, a first reinforcing rib is provided on the inner side wall of the first boom bracket, and the first reinforcing rib is located between the first clamping plate and the outer side wall of the first boom bracket.

[0016] The above arrangement, by providing the first reinforcing rib, strengthens the structure of the first boom support, thereby facilitating the transfer of the boom.

[0017] Furthermore, a second reinforcing rib is provided on the inner side wall of the second boom bracket, and the second reinforcing rib is located between the second clamping plate and the outer side wall of the second boom bracket.

[0018] The above arrangement, by providing the second reinforcing rib, strengthens the structure of the second boom support, thereby facilitating the transfer of the boom.

[0019] Furthermore, an accommodating space for accommodating the boom is formed between the first reinforcing rib, the second reinforcing rib, the first clamping plate and the second clamping plate.

[0020] The above arrangement can better clamp and fix the boom through the arrangement of the first reinforcing rib and the second reinforcing rib and the first clamping plate and the second clamping plate.

[0021] Furthermore, a hoisting space is provided between the first reinforcing ribs at both ends of the first boom bracket and between the second reinforcing ribs at both ends of the second boom bracket.

[0022] The above arrangement facilitates the lifting platform to lift the boom bracket by setting up the lifting space. BRIEF DESCRIPTION OF THE DRAWINGS
