Abstract

The invention provides a standard knot device and a tower crane, the standard knot device comprises a main chord member body, a male joint, a female joint and a pin shaft body, the male joint is arranged at the first end of the main chord member body, the male joint is provided with a first plug pin hole which is through in the radial direction, the female joint is a hollow circular pipe and is connected with the second end of the main chord member body, and the pin shaft body is arranged in the first plug pin hole; the outer diameter of the female joint is equal to the outer diameter of the main chord member body, the inner diameter of the female joint is smaller than the inner diameter of the main chord member body, a second bolt hole is formed in the female joint in a radial penetrating mode, and the female joint is arranged on the male joint of another adjacent standard knot device in a sleeving mode; the pin shaft body is used for being arranged in the first plug pin hole and the second plug pin hole in a penetrating mode to connect the two adjacent standard knot devices, a reinforcing plate on the outer side of the female connector is omitted, the problem that the manufacturing process of the reinforcing plate is complex is fundamentally solved, arrangement of idler wheels of a climbing frame is not limited, and therefore design of a climbing system is facilitated.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to a standard joint device and a tower crane. Background technique [0002] Tower cranes are commonly used lifting equipment in construction engineering operations. The main part of the tower body of the tower crane is composed of standard sections stacked from bottom to top. At present, the main chords of the circular pipe standard sections on the market are mainly connected by pin shafts. The pin holes at the joints of the main chords will cause local strength to be weakened. In order to reinforce the parts, generally A reinforcing plate is set outside the connection of the main chord, but in order to match the standard section of the round pipe, the shape of the reinforcing plate is irregular, the manufacturing process is complicated, and the setting of the reinforcing plate will have a certain impact on the design of the climbing frame and the rollers of the climbi...
