Description

Technical Field

[0001] The utility model relates to an anti - sway shelf for the extension of a platform for the main boom of a large crane, belonging to the technical field of offshore wind power construction platforms. Background Art

[0002] During the construction of offshore wind power, the wind turbine blades need to be assembled on the offshore wind power construction platform. Sometimes, in order to meet the requirements of wind turbine blade assembly, an oil drilling platform is transformed to form it. An offshore wind power construction platform usually needs to be equipped with a crane for hoisting wind turbine blades.

[0003] After the crane is installed, sometimes the boom of the crane is relatively long. When affected by the sea breeze, the relatively long boom of the crane needs to be stably supported on the offshore wind power construction platform to avoid shaking. The existing boom support technology can be seen in Chinese Patent Publication No. CN104802946B. Although the boom support structure can stably support the relatively long boom of the crane, the boom support structures are all rigid parts such as T - shaped steel, H - shaped steel, angle steel or channel steel that are in rigid contact with the boom, and there is a problem that the rigid contact of the crane boom is easy to wear. Summary of the Utility Model

[0004] To solve the above - mentioned technical problems, the utility model provides an anti - sway shelf for the extension of a platform for the main boom of a large crane.

[0005] The utility model is realized through the following technical solutions.

[0006] An anti - sway shelf for the extension of a platform for the main boom of a large crane provided by the utility model includes:

[0007] A support assembly that is fixed on the extension platform during installation and is inclined outward;

[0008] A rest pillow assembly fixed on the support assembly.

[0009] The rest pillow assembly includes a transition platform fixed on the top of the support assembly. An inclined pillar is fixed on the transition platform in an inclined manner; the middle parts between the inclined pillars are fixedly connected and strengthened by a connecting rod, and the top parts between the inclined pillars are fixedly connected and strengthened by a reinforcing plate;

[0010] A rest pillow platform is fixed on the top of the inclined pillar and the reinforcing plate. A limiting block is fixed on the inner surface of the rest pillow platform; the four limiting blocks are spaced apart on the rest pillow platform for contacting and placing the boom.

[0011] The inclined pillar inclines inward, which is opposite to the outward inclination of the support assembly.

[0012] The limiting block is an elastic rubber plate.

[0013] The support assembly includes an inclined column that inclines outward;

[0014] Horizontal supports for strengthening the fixed connection between inclined columns, long diagonal braces for strengthening the fixed connection between the upper horizontal supports, and short diagonal braces for strengthening the fixed connection between the lower horizontal supports.

[0015] A transition platform is fixed at the top of the inclined column.

[0016] The beneficial effect of the present utility model lies in that when a crawler crane or an offshore crane needs to be stabilized under the influence of sea breeze on a drilling platform, the boom of the crawler crane or the boom of the offshore crane is placed on the pillow platform at the top of the support assembly. At this time, the boom contacts the four equally spaced limit blocks on the pillow platform. Since the limit blocks are composed of elastic rubber plates, flexible damping contact between the boom and the pillow assembly is achieved, solving the problem that rigid contact between the rigid parts of the boom support structure and the boom is prone to wear.

[0026] The technical solution of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0027] As Figures 1 to 9 shown

[0028] The technical solution of this application is to fixedly connect or detachably connect a expansion platform 2 and an extension platform 6 by welding on the side of the drilling platform 7, and the platform space is expanded through the expansion platform 2 and the extension platform 6 on the drilling platform 7.

[0029] A traveling track 51 is installed on the expansion platform 2 and the drilling platform 7, and a crawler crane 52 is installed on the traveling track 51. A counterweight platform 53 for placing configuration blocks is installed on the drilling platform 7 at one end of the traveling track 51, and a platform extension anti-sway shelf 3 is installed on the extension platform 6 to support the boom 5 of the crawler crane 52, thus constituting a crawler crane layout structure on an oil drilling platform.

[0030] An offshore crane 71 is installed on the expansion platform 2, and a platform extension anti-sway shelf 3 is installed on the extension platform 6 to support the boom 5 of the offshore crane 71, thus constituting an offshore crane layout structure on an oil drilling platform.

[0031] Since the platform space is expanded by installing the expansion platform 2 and the extension platform 6 on the drilling platform 7, the crawler crane 52 is installed on the expansion platform 2 and the drilling platform 7 through the traveling track 51, or the offshore crane 71 is installed on the expansion platform 2, and the platform extension anti-sway shelf 3 is installed on the extension platform 6 to support the boom 5 of the crawler crane 52 or the offshore crane 71, which solves the problem that the space of the offshore wind power construction platform transformed from the oil drilling platform is small and cannot meet the installation of the crawler crane or the offshore crane.

[0032] The above-mentioned platform extension anti-sway shelf 3 for the main boom of a large crane in this application includes:

[0033] A support component 1 fixedly installed on the extension platform 6 and a sleeper component 2 fixed on the support component 1. The support component 1 inclines outward

[0034] The sleeper component 2 includes a transition platform 21 fixed on the top of the support component 1, and an inclined pillar 22 is fixedly inclined on the transition platform 21. The inclined pillar 22 inclines inward, which is opposite to the outward inclination of the support component 1; the middle parts between the inclined pillars 22 are fixedly connected and strengthened by a connecting rod 23, and the top parts between the inclined pillars 22 are fixedly connected and strengthened by a reinforcing plate 24;

[0035] A sleeper platform 25 is fixed on the top of the inclined pillar 22 and the reinforcing plate 24. A limiting block 26 is fixed on the inner surface of the sleeper platform 25, and the limiting block 26 is composed of an elastic rubber plate; the limiting block 26 is four and is distributed at intervals on the sleeper platform 25 for contacting and placing the boom 5.

[0036] When the crawler crane 52 or the offshore crane 71 needs to be stabilized under the influence of sea breeze on the drilling platform 7, the boom 5 of the crawler crane 52 or the boom 5 of the offshore crane 71 is placed on the pillow platform 25 at the top of the support assembly 1. At this time, the boom 5 contacts the four spaced-apart limit blocks 26 on the pillow platform 25. Since the limit blocks 26 are made of elastic rubber plates, flexible damping contact between the boom 5 and the pillow assembly 2 is achieved, solving the problem that rigid contact between the rigid parts of the boom support structure and the boom is prone to wear.

[0037] The support assembly 1 includes inclined columns 11 that slope outward. There are four inclined columns 11, and horizontal supports 12 for fixed connection and reinforcement are provided between the inclined columns 11. Long diagonal braces 13 for fixed connection and reinforcement are provided between the upper horizontal supports 12, and short diagonal braces 14 for fixed connection and reinforcement are provided between the lower horizontal supports 12. The transition platform 21 is fixed to the top of the inclined columns 11.

[0038] The extension platform 6 includes a platform panel 61 fixed to the drilling platform 7. An inclined support 63 is fixed to the lower part of the platform panel 61, and the inclined support 63 in an inclined state fixedly connects the platform panel 61 to the drilling platform 7. The inclined columns 11 of the support assembly 1 are fixed to the platform panel 61 of the extension platform 6. The extension platform 6 can be fixed to the bottom of the support assembly 1 to form an integral body, enabling the extension platform 6 to be matched with the support assembly 1 and making the extension platform 6 form a part of the support assembly 1.

[0039] A vertical support 34 is fixedly connected between the middle of the inclined support 63 and the middle of the bottom surface of the platform panel 61. The inclined columns 11 are located on the platform panel 61 at the top of the vertical support 34. A triangular plate 32 is fixed between the platform panel 61 and the top of the inclined support 63 for reinforcement.

[0040] A horizontal rod 35 is fixedly connected between the middle of the inclined support 63 and the drilling platform 7; a triangular plate 32 is fixed between the platform panel 61 and the top of the inclined support 63 for reinforcement. The inclined columns 11 are located on the platform panel 61 at the top of the inclined support 63.
