Embodiment 1

[0039] Such as Figure 2-7 As shown, in a standard section and connection device of a tower crane according to the present invention, the angle steels of the four main limb columns of the main limb column 1 are all angle steel structures with the same structural model, and the reinforcing connecting rod includes a first reinforcement Connecting rod 2, the second reinforcing connecting rod 5, described beam bar refers to or comprises first beam bar 3, second beam bar 7, and described upper connecting plate is to comprise left upper connecting plate 6, right upper connecting plate 8, so Described intermediate connecting plate comprises intermediate connecting plate 4, and described lower connecting plate comprises left lower connecting plate 6; Described pin plate comprises left lower pin plate 15 and right lower pin plate 17, has left lower pin on left lower pin plate 15. Shaft hole 1501, the lower right pin shaft plate 17 is provided with the lower right pin shaft hole 1701 as...

Embodiment 2

[0044] Except for the following descriptions, all the rest are the same as the descriptions in Embodiment 1 and the above-mentioned specific implementation manners.

[0045] Such as Figure 8 , 9 As shown, the connection structure adopted by the fixed standard section 21 of this embodiment is that the four main limb columns 1 of the angle steel structure are connected with the reinforcing connecting rod and the beam rod, and are directly fixedly connected to any adjacent two main limbs. on the inner wall corresponding to the angle steel of the column 1, or fixedly connected to the inner wall corresponding to the angle steel of any adjacent two main limb columns 1 through the upper connection plate, the middle connection plate, and the lower connection plate, and the reinforced connection The rod is in a zigzag structure and is directly or fixedly connected to the inner side walls of any adjacent two main limb columns 1 through the upper connecting plate and the lower connect...

Abstract

The invention provides a tower crane standard section and connecting device. The device comprises a standard section device and a pin shaft connecting locking device, the standard section device comprises four first main limb columns 1 with angle steel structures, a reinforcing connecting rod, a cross beam rod, an upper connecting plate, a middle connecting plate, a lower connecting plate and the like, the standard section main limb columns adopt the large angle steel structures, the problems of structural safety, high installation cost and the like of a tower crane the standard section can be fundamentally solved, and the potential safety hazard of human factors on standard section connection is eliminated in design. A welding mode is adopted in a whole structure, and the work of field assembly is omitted; sections are connected through the pin shafts, interlocking safety pins are arranged, so that the risk that bolts are loosened due to human errors or improper inspection can be greatly avoided, the potential safety hazard of the standard section connection is thoroughly eliminated, meanwhile, intelligent manufacturing is easy to achieve, and the market competitiveness of products is improved.

Description

Technical field: [0001] The invention relates to the field of tower cranes, mainly relates to the processing field of standard joints and connection devices of tower cranes, in particular to a standard joint and connection device of tower cranes. Background technique: [0002] At present, in the existing domestic tower crane installations, there are mainly two structural types of standard sections, one is an integrally fixed standard section connected by bolts, referred to as a bolt-fixed section. The other is a piece-type standard section in the form of a pin-shaft connection that can be split into four pieces, referred to as a pin-shaft piece-type section, see figure 1 , each has its advantages and disadvantages. [0003] For standard joints with bolt connection, the installation is convenient, but due to the characteristics of the structural design, due to the sharp change of the section at the main limb joint, it is easy to cause stress concentration, which in turn lead...
