Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes a tower body 7 fixed on the ground by a fixed foot 8 and composed of three standard joints. The outside of the tower body 7 is equipped with a jacking sleeve 6 controlled by the jacking device of the tower crane itself. The top is connected with the bottom of the rotary assembly 5 by pin shafts. The upper part of the slewing assembly 5 is connected with the tower head 3 through a pin shaft. On the outer side of the tower head 3, there is an outsourcing tower head 2 connected to it through a pin shaft 9. The two sides of the outsourcing tower head 2 are respectively connected to the balance arm 1 and the jib assembly 4 through a pin shaft, and the lower end is placed on the upper part of the jacking sleeve 6. .

[0012] Such as figure 2 As shown, disassemble the pin shaft connecting the tower head 3 and the upper part of the slewing assembly; start the jacking system to perform the jacking operation normally, ...

Abstract

The invention discloses an integral self-lifting device for upper equipment of a tower crane. The device comprises a tower body that is fixed on the ground through fixing anchors and composed of a plurality of standard sections, wherein the outer side of the tower body is sleeved with a jacking sleeve frame, and the upper part is connected to the lower part of a rotary assembly through a hinge pin; the upper part of the rotary assembly is connected to a tower head through a hinge pin; the outer side of the tower head is sleeved with an enveloping tower head that is connected to the tower headthrough a hinge pin, both sides of the enveloping tower head are respectively connected to a balance arm and an arm frame assembly through hinge pins, and the lower end is placed on the upper part ofthe jacking sleeve frame. The integral self-lifting device for the upper equipment of the tower crane can prevent the superstructure of the tower crane from instability and tilting when the tower crane is in strong wind, bad weather and other conditions during the construction, and achieve the integral self-lifting requirements of the upper part of the tower crane. The integral self-lifting deviceis simple in structure, reasonable in resign and humanized in the integral structure, and greatly improves the safety of the tower crane.

Description

technical field [0001] The invention belongs to the technical field of tower cranes, and relates to an overall self-elevating device for the upper part of the tower crane. Background technique [0002] A few days ago, during the construction of the project, there are many marine climate environments. In the case of strong winds and bad weather during construction, the upper part of the tower crane has a large windward area, and the probability of overall tipping is relatively high. Due to the limitations of the existing structure, if the tower body is not lowered by dismantling the standard section after erecting the tower, the jib frame and the balance arm cannot be raised and lowered freely. On the premise of ensuring safety without reducing functions, satisfying the rapid self-elevating of tower crane jib and balance arm is a new direction for the diversified development of tower cranes. Contents of the invention [0003] The purpose of the present invention is to prov...
