Description

Technical Field

[0001] This utility model relates to the field of standard section technology, and in particular to a standard section connection structure for tower cranes. Background Technology

[0002] Tower crane standard sections are core steel structure components of cranes, tower cranes, and other equipment. They are used to change the height of the tower and enhance the stability and safety of the equipment. The main body is constructed by welding four seamless steel pipe main limbs with a triangular steel frame. Standard sections are generally assembled in a modular fashion to meet the construction needs of tower cranes of different heights. The weight of a single section is strictly controlled within the range of 450-500 kg, which facilitates transportation and on-site hoisting.

[0003] Currently, the installation structure of most standard tower crane sections is located on the side wall of the standard section. The upper and lower standard sections are fixed by the connecting structure installed on the side wall. This connecting structure located on the side wall is prone to swaying in extreme winds. Therefore, the current standard section connection structure has limited wind resistance. At the same time, in order to facilitate personnel to enter and exit the tower crane cab, ladders are usually installed inside the standard section for personnel to climb. However, since tower cranes are generally quite tall, personnel sometimes need to rest in between while climbing. The current standard section lacks a place for personnel to rest temporarily.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a standard section connection structure for tower cranes, solving the problems mentioned in the background section.

[0022] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5This utility model provides a technical solution for a standard section connection structure for tower cranes: It includes a standard section body 100, with fixed posts 200 fixedly installed at the four corners of the upper part of the outer wall of the standard section body 100. A cross-shaped insertion post 210 is fixedly connected to the upper part of the outer wall of the fixed post 200, and threaded holes 410 are provided on the cross-shaped insertion post 210. A connecting plate 300 is fixedly installed at the lower part of the outer wall of the standard section body 100, and a sleeve 310 is fixedly connected to the lower part of the outer wall of the connecting plate 300. A cross-shaped insertion groove 320 is provided on the upper part of the inner wall of the sleeve 310. The cross-shaped insertion slot 320 is inserted into the cross-shaped insertion post 210. When the standard section body 100 needs to be installed, the upper standard section body 100 is moved above the lower standard section body 100 by a crane. The position of the upper and lower standard section bodies 100 is initially positioned and aligned by the insertion between the sleeve 310 and the fixing post 200. Then, the position of the upper and lower standard section bodies 100 is locked by the insertion between the cross-shaped insertion slot 320 and the cross-shaped insertion post 210, reducing horizontal swaying during connection. The outer wall of the sleeve 310 has a connecting hole 400 that penetrates the cross-shaped insertion slot 320. A locking screw 420 that is threaded into the threaded hole 410 is inserted into the connecting hole 400. A fixing nut 430 is threaded onto the locking screw 420.
