Limited by the existing structure, if the tower body is lowered without disassembling the standard section after the tower is erected, the arm support and the balance arm can not be lifted freely. On the premise of ensuring safety and not reducing functions, the requirement that the arm support and the balance arm of the tower crane quickly and automatically lift is met, and the method is a new direction for diversified development of the tower crane.
Disclosure of Invention
The invention aims to provide the integral self-lifting device of the upper equipment of the tower crane, which has a simple structure and reasonable design and can effectively overcome the defects that the tower body is lowered without disassembling a standard knot and an arm support and a balance arm cannot be lifted freely in the existing tower crane.
The technical scheme adopted by the invention is as follows: the self-lifting device comprises a tower body which is fixed on the ground through fixed ground feet and is constructed by a plurality of standard sections, wherein a lifting sleeve frame is sleeved on the outer side of the tower body, and the upper part of the tower body is connected with the lower part of a rotary assembly through a pin shaft; the upper part of the rotary assembly is connected with the tower head through a pin shaft; the method is characterized in that: the outer side of the tower head is sleeved with an outer-coated tower head connected with the tower head through a pin shaft, the two sides of the outer-coated tower head are respectively connected with a balance arm and an arm support assembly through pin shafts, and the lower end of the outer-coated tower head is arranged at the upper part of the jacking sleeve frame.
By adopting the structure, when the tower crane works, the outsourcing tower head is connected with the tower head, the arm support assembly and the balance arm through the pin shafts respectively, the lower part of the outsourcing tower head is separated from the jacking sleeve frame, and the sleeve frame returns to a position below the rotary support, so that the normal rotation and suspension state of the tower crane is realized; when the tower crane is in a self-lifting state, the jacking sleeve frame jacks to the lower part of the outer-coated tower head and is connected with the outer-coated tower head through a pin shaft, the pin shaft for connecting the outer-coated tower head with the tower head is disassembled from the upper part, so that the arm support assembly, the balance arm, the outer-coated tower head and the jacking sleeve frame are integrated, the integral lifting process of the upper part of the tower crane is completed by utilizing the jacking device of the tower crane, and the free lifting can be realized under the condition of not lowering the. The invention can meet the requirements of the tower crane on the instability and the tipping of the upper structure of the tower crane in the conditions of strong wind, severe weather and the like during construction, and the integral self-lifting requirement of the upper part of the tower crane is realized. The invention has simple structure, reasonable design and humanized overall structure, and greatly improves the safety of the tower crane.

Detailed Description
As shown in figure 1, the invention comprises a tower body 7 which is fixed on the ground through a fixed foot 8 and is composed of 3 standard sections, a jacking sleeve frame 6 controlled by a jacking device of a tower crane is sleeved outside the tower body 7, and the upper part of the tower body is connected with the lower part of a rotary assembly 5 through a pin shaft. The upper part of the rotary assembly 5 is connected with the tower head 3 through a pin shaft. The outer side of the tower head 3 is sleeved with an outer-coated tower head 2 connected with the outer-coated tower head through a pin shaft 9, two sides of the outer-coated tower head 2 are respectively connected with a balance arm 1 and an arm support assembly 4 through pin shafts, and the lower end of the outer-coated tower head is arranged at the upper part of the jacking sleeve frame 6.
As shown in fig. 2, the pin shaft connecting the tower head 3 and the upper part of the slewing assembly is detached; and the jacking system can be started to normally carry out jacking operation, so that the number of standard knots and the height of the tower crane are increased or reduced.
As shown in fig. 3, when the tower crane reaches the free height, the pin shaft connecting the outer-coated tower head 2 and the jacking sleeve frame 6 is detached, the jacking sleeve frame 6 descends to a position below the slewing assembly 5, and the jacking cross beam and the hanging shoe are fixed at a fixed position below the slewing assembly 5, so that the tower crane can normally perform slewing operation.
As shown in fig. 4, when the working environment meets a strong wind weather or an urgent need to drop the boom assembly 4 and the balance arm 1 to the ground, the jacking sleeve frame 6 can be lifted to the lower part of the outsourcing tower head 2 and connected by using the pin shaft, the pin shaft 9 connecting the outsourcing tower head 2 and the tower head 2 is disassembled, and the jacking device is started, so that the boom assembly 4 and the balance arm 1 can be quickly dropped to the ground.
