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 utility model aims at providing a simple structure, reasonable in design can effectively overcome current tower crane, do not dismantle standard festival and reduce the body of the tower, and the unable tower crane upper portion equipment that freely goes up and down of cantilever crane, balance arm is whole from elevating gear.

The utility model adopts the technical proposal that: the self-lifting device comprises a tower body which is fixed on the ground through fixed ground feet and consists of a plurality of standard joints, wherein a lifting sleeve frame is sleeved outside 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 utility model discloses can satisfy tower crane meet under the condition such as strong wind and bad weather in the construction, avoid tower crane superstructure unstability to tumble, realize that tower crane upper portion is whole from the requirement of going up and down. The utility model has the advantages of simple structure and reasonable design, overall structure is humanized, has increased tower crane's security by a wide margin.

Detailed Description

As shown in fig. 1, the utility model discloses a fix subaerial, by the body of the tower 7 that 3 standard festivals constitute through fixed lower margin 8, this body of the tower 7 outside cover is equipped with the jacking stock 6 by the jacking device control of tower machine itself, and the lower part connection of round pin axle and gyration assembly 5 is passed through on upper portion. 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.
