Abstract

The invention discloses a plug-in connection structure and a crane. The plug-in connection structure is used to connect the vehicle frame with the outrigger; the plug-in connection structure includes a two-way oil cylinder, an upper bolt and a lower bolt. The upper pin is arranged in the frame, the first end of the two-way oil cylinder is connected to the upper pin; the lower pin is arranged in the leg; when the frame is connected to the leg , the lower bolt is connected to the second end of the two-way oil cylinder, and the two-way oil cylinder respectively drives the movement of the upper bolt and the lower bolt so that the upper and lower parts of the frame are respectively connected to the legs. The upper part and the lower part are connected. The crane of the present invention includes the above-mentioned plug-in connection structure, which avoids the problem of connecting and disassembling the oil circuit during the connection and disassembly of the traditional vehicle frame and outriggers, improves the installation and disassembly efficiency of the vehicle frame and outriggers, and saves manpower.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a plug-in connection structure and a crane. Background technique [0002] The outrigger is one of the main components of the lifting equipment. Its function is to increase the supporting base of the lifting equipment, reduce the burden on the tires, improve the stability of the vehicle against overturning, and thus increase the lifting capacity. For large-tonnage and super-large-tonnage lifting equipment, the weight of the whole vehicle usually reaches more than 50 tons. In order to reduce the weight of the lifting equipment during transfer, the outriggers need to be removed and transported separately. The outriggers are connected to the frame of the lifting equipment during operation. Get up and remove the outriggers when the work is done. [0003] figure 1 It is a structural schematic diagram of the separation of the vehicle frame and the legs in the pr...
