Description
Technical field
The utility model belongs to construction machine equipment technical field, relates generally to a kind of the quick of large-scale inside-climbing tower crane
Provision for disengagement.
Background technique
It is big that super high-rise building high-altitude tower crane removes difficulty：Tower crane removes narrow space, and removes disintegration and vertical transport all
In high aerial progress operation, is influenced by external decoration, need remote hoisting transportation.It is hidden that super high-rise building high-altitude tower crane removes safety
Suffer from more：In Super High construction, tower crane crane arm is suspended in the high-altitude of hundred meters or even several hundred meters, and setting safety devices are more difficult, herein
The disassembly that crane arm is carried out under the conditions of kind, has certain risk.It is big that super high-rise building high-altitude tower crane removes cost：Such as
It under the premise of where guaranteeing safety, reduces tower crane and removes cost, be the emphasis for formulating tower crane Demolition Construction scheme.
Super high-rise building generallys use inner climbing crane tower and carries out steel construction skyscraper lifting construction.Climbing tower lifting
Machine takes full advantage of the height of building itself, and covering construction area efficiency is high, and high-building construction use is safer, no
Construction site is occupied, is suitable for the engineering of narrow space, without multiple tracks attachment device and a large amount of tower-body standard section in use
Investment, there is the significant overall economic efficiency of comparison, and especially for the construction of special high-rise, what is do not replaced almost is risen
Heavy-duty machine.
For climbing tower crane after the completion of construction, in high-rise, super high rise building top, disassembly is difficult,
Crane arm especially therein, due to lifting the needs of function, quite a few of crane arm has exceeded the top horizontal of building
Face, is suspended in tens of rice, more than hundred meters, even several hundred meters of high-altitude, even if the part within building vertical plane, because building function
It can be made with reasons, super high rise structure complexity such as shape Art Designs to the high-altitude dismantling of climbing tower crane, transhipment operation
It is a technology complexity, the work that difficulty of construction is big at certain difficulty.
At present in construction, the disassembly of large-scale inside-climbing tower crane needs to be less than by an energy level medium-sized tower of one shelves
It hangs, the dismounting of the medium-sized tower crane needs the small-sized tower crane by a smaller energy level again, and the dismounting of the small-sized tower crane must be by can oneself
The tower crane torn open is completed, and dismounting process efficiency very cumbersome in this way is larger compared with low-risk, and expense cost is also relatively high.
Utility model content
The utility model proposes a kind of quick provisions for disengagement of large-scale inside-climbing tower crane, can be completed by once mounting
Large-scale tower crane is removed, and after having removed large-scale tower crane, can voluntarily be disintegrated, and is transported to ground by artificial etc., this will significantly
Reduce the cost and risk for removing large-scale tower crane.
In order to achieve the above object, the utility model proposes a kind of quick provisions for disengagement of large-scale inside-climbing tower crane, including：
Elevator boom rack；
A frame is connected to the elevator boom rack；

The luffing power mechanism is connected to after frame support；
Stock is connected to the elevator boom rack and A frame, and integral demounting device is installed on inside-climbing tower crane.
Further, the stock is connected to the lifting power machine structure on inside-climbing tower crane top by wirerope, passes through steel wire
Rope band is dynamic, and provision for disengagement is made to be increased to certain height.
Further, the provision for disengagement installs in inside-climbing tower crane large arm and is fixed temporarily wirerope, for large arm of disintegrating
When, keep the stable structure of its remainder.
Further, the luffing power mechanism pulls hoist rope, realizes the angle change of elevator boom rack, can
Get at the angle that disassembly large arm can be lifted up to one.
Further, the provision for disengagement, which is decomposed and is segmented, removes large arm and tower body.
Further, the endpoint of the elevator boom rack is provided with suspension hook.
The utility model proposes large-scale inside-climbing tower crane quick provision for disengagement, after the provision for disengagement, large size in climb
The dismounting of tower crane does not need to tear heavy-duty hoisting equipment open certainly by medium-sized tower crane, small-sized tower crane and other smaller ranks, substantially reduces
Equipment application risk and expense, save the duration.
Detailed description of the invention

Specific embodiment
Specific embodiment of the present utility model, but the utility model implementation not limited to the following are provided below in conjunction with attached drawing
Mode.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that attached drawing
It is all made of very simplified form and uses non-accurate ratio, be only used for convenience, lucidly aid in illustrating the utility model
The purpose of embodiment.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 show the quick disassembly of the large-scale inside-climbing tower crane of the utility model preferred embodiment
Apparatus structure schematic diagram, Fig. 2 show the structural schematic diagram of elevator boom rack and A frame.The utility model proposes climb in a kind of large size
The quick provision for disengagement of tower crane, including：Elevator boom rack 100；A frame 200 is connected to the elevator boom rack 100；Luffing power mechanism
300, the endpoint of the elevator boom rack 100 is connected to by hoist rope 400, the hoist rope 400 passes through A frame 200
