Abstract

The invention discloses an insert-pull connection structure, a supporting leg and a frame connection assembly and a crane. The insert-pull connection structure is used for enabling a frame to be connected with the supporting leg, the insert-pull connection structure comprises a bidirectional oil cylinder, an upper bolt and a lower bolt, wherein the first end of the bidirectional oil cylinder is used for driving the upper bolt, so that the upper part of the frame is connected with the upper part of the supporting leg through the upper bolt, the second end of the bidirectional oil cylinder is used for driving the lower bolt, so that the lower part of the frame is connected with the lower part of the supporting leg through the lower bolt. The supporting leg and the frame connection assembly and the crane comprises the above insert-pull connection structure, so that the problems that a traditional frame is connected with the supporting leg and the traditional frame is also connected with the supporting leg during the dismantle process and the disassemble of an oil channel are solved, so that the mounting and dismounting efficiencies of the frame and the supporting legs are improved, and the labor is saved.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a plug-in connection structure, an outrigger and vehicle frame connection assembly and a crane. Background technique [0002] The outrigger is one of the main parts 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 separat...
