Abstract
The utility model relates to the field of engineering machinery and discloses a large movable arm tower crane introduction mechanism. The large movable arm tower crane introduction mechanism comprises a bent introduction cross beam, a pull rod I, a platform, an electric introduction bogie, a special lifting hook and a special hanger. The introduction bogie of the large movable arm tower crane introduction mechanism is driven by a three-in-one reducing motor, and compared with a traditional introduction mechanism, the electric introduction bogie needs power supply, thereby being always arranged on the introduction cross beam; the special hanger is used for lifting standard knots in jacking and knot adding process, the special hanger and the standard knots are placed on the electric introduction bogie in the introduction process of the standard knots, thereby solving the problem that the traditional introduction mechanism is unlikely to introduce the standard knots; and the introduction cross beam of the utility model is bent, thereby effectively solving the problem that the introduction cross beam of the traditional introduction mechanism is liable to interfering with a lifting cable wire, expanding the working range of the tower crane and improving the application safety of the tower crane.
Description
Technical field
The utility model relates to engineering machinery field, and particularly a kind of large-scale swing arm tower crane is introduced mechanism.
Background technology
At present, China's high-rise building is in and rises and development stages, and the high-rise building altitude record of China all constantly is being refreshed every year.Many high-rise buildings are rised sheer from level ground after entering 21 century, and following 10 to 15 years, China will form huge high-rise building market.
Simultaneously, electric power resource is the basis of commercial production and people's lives, and China's oil, water resources lack, and therefore in quite over a long time, thermal electric generation is the emphasis of China's economic construction.The emphasis of construction of fire and electricity, difficult point are the installations of boiler, comprise boiler workshop steel structure, internal unit, peripheral facility.Boiler island is thermal power plant's high building except chimney, and volume maximum, installation difficulty are big in power plant's construction.
In order to satisfy the demand of high-rise building engineering and construction of fire and electricity, the swing arm tower crane is towards large scale development, and work range is increasing, and body of the tower self steel structure is also more and more heavier.Along with the rising of building height, the external climbing tower crane need satisfy further construction demand by the mode of jacking supernumerary segment usually.
For large-scale swing arm tower crane, if adopt traditional introduction mechanism during the jacking supernumerary segment then have two large problems.On the one hand, traditional introduction mechanism all adopts manpower to drive, but body of the tower volume and the quality of large-scale swing arm tower crane are big, and operating personal can't spur, and cause standard knot to introduce difficulty, and in unloading process, standard knot also is difficult for drawing.On the other hand, when the swing arm tower crane was worked down by a small margin in galianconism length, tower crane self suspension hook was easily interfered with the introduction crossbeam, causes hoist rope to wear and tear, and brings a series of hidden danger to working security.In addition, it is oversize to introduce crossbeam, all will make troubles for processing, assembling and transportation.
Figure 1 shows that traditional introduction structural scheme of mechanism.Formed by introduction crossbeam 1, pull bar 2, platform 3, introduction dolly 4, suspension hook 5.Supply to introduce carriage walking by the track of being formed by shaped steel on it.The shortcoming of this scheme is: take manpower to drive in (1) standard knot introducing process, when tower crane self steel structure is heavier, standard knot can't be introduced; (2) it is not bent to introduce crossbeam, when the swing arm tower crane long by a small margin down during work at galianconism, suspension hook and hoist rope easily with introduce crossbeam and interfere, exist potential safety hazard; (3) the introduction crossbeam is long, is not easy to install and transportation.
Summary of the invention
The purpose of this utility model is: introduce the technical matters that mechanism exists for solving above-mentioned tradition, provide a kind of large-scale swing arm tower crane to introduce mechanism, can solve standard knot is difficult for introducing, the problem of workmen's processing safety and convenience difference, can solve tower crane again when working down by a small margin, the easy and introduction crossbeam interference problem of hoist rope.
For achieving the above object, the technical solution adopted in the utility model is: provide a kind of large-scale swing arm tower crane to introduce mechanism, comprising: folding type is introduced crossbeam 6, pull bar I 7, platform 8, electronic introduction dolly 9, special-purpose suspension hook 11, special hanger 10;
Described folding type is introduced crossbeam 6 and further comprised: front-axle beam 13, the back rest 14 connect by bearing pin 15 between the two, and removably connect between the two; Folding type is introduced crossbeam 6 upper ends and is provided with platform 8, and midway location is provided with the hinge ear, and the bottom is provided with electronic introduction dolly stroke limit plate, and folding type is introduced horizontal 6 and is connected by bolt with electronic introduction dolly stroke limit plate, can dismantle;
Described pull bar I 7 one ends and tower crane undersetting 12 are hinged, and it is hinged that the other end and folding type are introduced crossbeam 6;
Described electronic introduction dolly 9 is for the actuating device of introducing standard knot 20, further comprises: 2 three-in-one reducing motors 16, trolley frame 17, driving wheel 18, flower wheel 19; Three-in-one reducing motor 16 is connected with trolley frame 17 by flange, and driving wheel 18 is connected with axle drive shaft on the reducing motor by flat key, and flower wheel 19 is positioned on the trolley frame 17 by end cap, antifriction-bearing box, threaded shaft and circular nut, and trolley frame 17 is provided with positioning groove;
Described special hanger 10 is to lift by crane standard knot 20 and be placed on device on the electronic introduction dolly 9, further comprises: cylindrical piece 23, location side plate 22, otic placode 21; The inboard, upper end of location side plate 22 is provided with cylindrical piece 23, and the outside is provided with suspension hook suspended structure 26, and cylindrical piece 23 is placed in trolley frame 17 positioning grooves, and both sides are by location side plate 22 location;
Described special-purpose suspension hook 11 is the structures of lifting by crane special hanger 10 and standard knot 20, and it hangs on the suspension hook suspended structure 26.
The beneficial effects of the utility model are: (1) introduction dolly of the present utility model adopts three-in-one reducing motor to drive, and introduces mechanism with tradition and compares, and electronic introduction dolly must be placed on all the time and introduce on the crossbeam owing to need power supply; The lifting standard knot was placed on special hanger and standard knot on the electronic introduction dolly in the standard knot introducing process when specialty suspender was used for the jacking supernumerary segment, had solved traditional introduction mechanism standard joint and had been difficult for problems such as introduction.(2) the utility model is introduced the mode that adopts bending in the crossbeam, efficiently solves that tradition introduces that mechanism introduces crossbeam easily and problem such as hoist rope interference, has enlarged the operating range of tower crane, has improved the tower crane safety in utilization.
