Embodiment Construction

[0024] Such as Figure 1-3 As shown, the rotating tooling of the standard section of the tower crane includes an underframe 1 and a rotating mechanism 2. The rotating mechanism is rotatably connected to the underframe 1 through the long axis 3 and the short axis 4 at both ends of the rotating mechanism. It is composed of connecting columns 6 connected to the four corners of the wall panels at both ends. One end wall panel is provided with a fixed main rotary rod positioning shaft 7, and the other end wall panel is correspondingly provided with a main rotary rod jacking mechanism 8 for telescopic positioning.

[0025] Such as Figure 4 As shown, the jacking mechanism includes a hand wheel 9, a linkage plate 10, a screw mandrel 11, a positioning shaft 12, a positioning bushing 13, a screw mandrel overcoat 14 and a top tightening sleeve 15, and the positioning bushing 13 and the screw mandrel overcoat 14 are fixed on In the reserved hole of the wallboard, the positioning shaft 1...

Abstract

A tower crane standard section rotating tool is characterized by comprising a base frame (1) and a rotating mechanism (2). The rotating mechanism is rotationally connected with the base frame (1) via a long shaft (3) and a short shaft (4) respectively at two ends of the rotating mechanism, and is formed by two end wall plates (5) and connecting columns (6) connected at four corners of the two end wall plates. One of the end wall plates is provided with a fixed main rotating rod positioning shaft (7), the other end wall plate is correspondingly provided with a flexibly positioned main rotating rod tight-propping mechanism (8), and both the end wall plates are provided with support block positioning backup plates. During splicing standard sections by the tower crane standard section rotating tool, on one hand, the tight-propping mechanism is utilized to position and mount a main rotating rod so as to guarantee accuracy and perpendicularity of diagonal lines of the standard sections to the maximum extent; and on the other hand, positioning and welding of supporting blocks can be realized better. Due to improvement of processing accuracy, interchangeability of the standard sections is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a standard joint device used in tower cranes. Background technique [0002] The existing tooling for the standard section of tower cranes is fixed to the wall, and the positioning pin is used to locate the main chord. Tailored and welded together, welding needs to be performed after exiting the tooling, and the production efficiency is low. Contents of the invention [0003] In order to overcome the deficiencies of the prior art above, the present invention provides a tower crane standard section rotary tool, which can effectively complete the tailor welding of the whole standard section in the same tool, and can improve positioning accuracy and product quality. [0004] The technical scheme adopted in the present invention is: [0005] The standard section rotary tooling of tower cranes has a structural feature: it includes an underframe and a rotating mechanism. The f...
