The utility model discloses the security of tower crane improves greatly, improves operational environment, reduces the human error, and fundamentally improves the security, and swing arm tower crane becomes width of cloth operation in -process, reduces cantilever crane axle power, simplifies amplitude changing device simultaneously and reduces the complete machine cost.
Description
Technical field
The utility model relates to technical field of engineering machinery, is specially a kind of arm tower crane.
Background technology
The many luffing motions being realized jib by luffing winch and the luffing pulley block system be arranged between Shears and luffing arm-tie of existing arm tower crane, this mode often needs high-performance luffing winch, cause complete machine high cost, on Shears, the relative complete machine in luffing fixed pulley locus fixedly causes, along with amplitude increase luffing arm-tie and jib axis angle diminish, increase jib axle power, accelerate the decay of far-end hoisting capacity to a certain extent.
Utility model content
The purpose of this utility model is to provide a kind of arm tower crane, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of arm tower crane, comprise foundation, amplitude oil cylinder, Shears, luffing arm-tie, jib, front strut, board and pivoting support, described foundation is fixed with base pitch, described base pitch is provided with tower-body standard section successively, described tower-body standard section has been bolted climbing support, described climbing support is provided with undersetting, described swing bearing is arranged on undersetting, described swing bearing is fixed with upper bracket, described board is fixed on upper bracket by binding bolt, the end of described luffing arm-tie is hinged on jib, described amplitude oil cylinder is arranged between luffing arm-tie and the board of hoisting crane, described front strut one end is hinged on the board of hoisting crane, the other end is hinged on the initiating terminal of luffing arm-tie, described Shears is arranged between luffing arm-tie and amplitude oil cylinder.
Preferably, described tower-body standard section is provided with and marks time.
Preferably, the middle part of described climbing support and medium position are provided with platform.
Preferably, described luffing arm-tie, jib, board and amplitude oil cylinder form quadrilateral frame shelf structure.
Compared with prior art, the beneficial effects of the utility model are: this arm tower crane, the safety of tower crane improves greatly, improve working environment, avoid the fatigue of operating personal to operate, reduce human error, fundamentally improve safety, in arm tower crane luffing operation process, reduce jib axle power, simplify luffing mechanism simultaneously and reduce complete machine cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, foundation, 2, base pitch, 3, climbing support, 4, undersetting, 5, upper bracket, 6, amplitude oil cylinder, 7, Shears, 8, luffing arm-tie, 9, jib, 10, front strut, 11, board, 12, pivoting support, 13, tower-body standard section.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of arm tower crane, comprise foundation 1, amplitude oil cylinder 6, Shears 7, luffing arm-tie 8, jib 9, front strut 10, board 11 and pivoting support 12, foundation 1 is fixed with base pitch 2, base pitch 2 is provided with tower-body standard section 13 successively, tower-body standard section 13 is bolted climbing support 3, climbing support 3 is provided with undersetting 5, swing bearing 12 is arranged on undersetting 4, swing bearing 12 is fixed with upper bracket 5, board 11 is fixed on upper bracket 5 by binding bolt, the end of luffing arm-tie 8 is hinged on jib 9, amplitude oil cylinder 6 is arranged between the board 11 of luffing arm-tie 8 and hoisting crane, front strut 10 one end is hinged on the board 2 of hoisting crane, the other end is hinged on the initiating terminal of luffing arm-tie 8, Shears 7 is arranged between luffing arm-tie 8 and amplitude oil cylinder 6, tower-body standard section 13 is provided with marks time, middle part and the medium position of climbing support 3 are provided with platform, luffing arm-tie 8, jib 9, board 11 and amplitude oil cylinder 6 form quadrilateral frame shelf structure.
Principle of work: when amplitude oil cylinder 6 is stretched out, jib 9 is relied on to conduct oneself with dignity and lift heavy, jib 9 is around hinge-point clickwise, and drive luffing arm-tie 8 to rotate, jib 9 elevation angle reduces amplitude and increases, when the contraction of amplitude oil cylinder 6, overcome the moment that jib 9 is conducted oneself with dignity and lift heavy produces, jib 9 is around hinge-point left-hand revolution, and drive luffing arm-tie 8 to rotate, the jib elevation angle increases amplitude and reduces, luffing arm-tie 8 plays tensioning function in the process, amplitude oil cylinder 6 in whole amplitude changing process is made to be subject to pulling force all the time, luffing arm-tie 8 remains unchanged with the angle of jib 9 simultaneously, thus effectively reduce significantly jib 9 axle power.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
