Description

Split type arm tower crane Shears structure
Technical field
The utility model relates to a kind of Shears structure, particularly relates to a kind of split type arm tower crane Shears structure.
Background technology
Shears is the important component part of arm tower crane, and it is arranged on the equilibrium arm of tower machine by pinned connection mode, is connected with amplitude draw-bar by variable-amplitude steel wire rope with crane arm.As depicted in figs. 1 and 2, existing Shears is generally made up of front pole-bracket (1-1) and back pole-bracket one (1-2); Front pole-bracket (1-1) is connected with equilibrium arm, near crane arm side; Back pole-bracket (1-2) is connected with equilibrium arm, and vertical with equilibrium arm, near counterbalanced weight side.Two front pole-brackets be oppositely arranged (1-1) are being parallel to each other perpendicular in the plane of equilibrium arm, and two back pole-bracket be oppositely arranged (1-2) structures are becoming with equilibrium arm in the plane at inclination angle to be parallel to each other.Front pole-bracket (1-1) top is connected with back pole-bracket one (1-2) pin shaft III (1-5), and front pole-bracket (1-1) bottom is connected with equilibrium arm pin shaft II one (1-4), and back pole-bracket one (1-2) bottom is connected with equilibrium arm bearing pin I 1 (1-3).Front pole-bracket (1-1) is provided with cat ladder one (1-6) structure, front pole-bracket (1-1) main string has welded cat ladder and installed otic placode (1-7), cat ladder fixed bearing (1-9) to be connected with this otic placode (1-7) with two bearing pins (1-8) and to be fixed on front pole-bracket (1-1).Cat ladder fixed bearing (1-9) is welded with bolt and connects otic placode (1-9.1), cat ladder erects in version (1-6.1) and is drilled with bolt connecting hole, and cat ladder one (1-6) is connected otic placode (1-9.1) by bolt with the bolt on cat ladder fixed bearing (1-9) and connects.
But there is following technical disadvantages in existing Shears: 1, processing and manufacturing, transport inconvenience.For the stability of bondsman's cabinet frame, front pole-bracket (1) main string generally designs to obtain overlength.The structure of this overlength gives processing, transport brings many troubles, not only makes, traffic cost is very high, and the structure of overlength can not meet freight container lower than the General Requirements of 12 meters, and the tower machine of outlet must customize special freight container.
2, inconvenience is installed, cost is high.In installation process, need first front pole-bracket (1-1) and back pole-bracket one (1-2) pin shaft III (1-5) to be connected as one; Then, with a hoisting crane, Shears is sling, front pole-bracket (1-1) pin shaft II one (1-4) is connected on equilibrium arm.Owing to only connecting by pin shaft III (1-5) between front pole-bracket (1-1) and back pole-bracket one (1-2), relatively rotate, under gravity, back pole-bracket one (1-2) and front pole-bracket (1-1) are close together, need with another hoisting crane, back pole-bracket one (1-2) to be pulled open, then use bearing pin I 1 (1-3) to be connected on equilibrium arm by back pole-bracket one (1-2).Installing at least needs two hoisting cranes to be used in conjunction with each other, and operating process bothers, and cost of installation is very high.
3, need other people to coordinate when cat ladder one (1-6) is installed, install loaded down with trivial details time-consuming.Due to cat ladder one (1-6) form with bolts, need people's staircase, a people twists bolt, and cooperating just can complete smooth installation.Each handling need to load and unload multiple bolt, more loaded down with trivial details, expend time in longer.
Summary of the invention
For the deficiency existed in existing structure form, in order to reduce the cost of Shears processing and fabricating, transport, in order to more convenient and efficient in installation, dismounting use procedure, the utility model provides a kind of split type arm tower crane Shears structure.
For achieving the above object, one of the present utility model split type arm tower crane Shears structure, comprise front pole-bracket, back pole-bracket and be connected to the cat ladder at front pole-bracket top by fixed bearing, and the bottom of front pole-bracket is connected with equilibrium arm, its top is connected with the top of back pole-bracket, and the bottom of back pole-bracket is connected with equilibrium arm; Described front pole-bracket is the split-type structural primarily of upper front pole-bracket and lower front pole-bracket composition; Also be provided with end wall bracket between described front pole-bracket and back pole-bracket, be connected bottom this end wall bracket with bottom back pole-bracket, its top is connected with in the middle part of lower front pole-bracket.
As from the foregoing, improvement of the present utility model is main in the following areas: first, main for Shears front pole-bracket chord length classifying rationally is become two sections, is designed to the split-type structural be made up of upper front pole-bracket and lower front pole-bracket, and uses pinned connection between upper front pole-bracket and lower front pole-bracket.Secondly, between front pole-bracket and back pole-bracket, design a kind of end wall bracket structure, this end wall bracket one end bearing pin is hinged with lower front pole-bracket, and other end bearing pin is connected with back pole-bracket, since then front pole-bracket, back pole-bracket, end wall bracket formation triangle stability structure.
In addition, described cat ladder fixed bearing is provided with cover of wedge, cat ladder is provided with hook, and hang among cover of wedge, and spring cotter is installed.
Further, the junction of upper and lower front pole-bracket is respectively equipped with otic placode, and is coupled together by otic placode by pin shaft II.
Compared to the prior art, this Shears structure has following advantage: 1, reduce processing and fabricating, traffic cost.The main string of Shears front pole-bracket generally designs overlength, and processing and fabricating bothers, and outlet needs special Container Transport.Main string, by front pole-bracket length classifying rationally, is divided into two sections by the utility model, is designed to two sections of upper front pole-brackets with pinned connection and lower front pole-bracket split-type structural form.The split-type structural of this pinned connection, easy for installation, processing and fabricating is simple, is convenient to transport, reduces processing and fabricating, traffic cost.
2, installation, convenient disassembly, reduces cost of installation.The Shears structure be made up of front pole-bracket, back pole-bracket and end wall bracket is a kind of triangle rock-steady structure, can realize integral installation.In installation process, only with a hoisting crane, Shears can be sling, then respectively front pole-bracket is connected with equilibrium arm with back pole-bracket bearing pin, reduce installation difficulty, reduce the set-up time, reduce cost of installation.
3, cat ladder is easy for installation, consuming time short.The utility model adopts fast-assembling type cat ladder structure, only cat ladder fixed bearing need be installed by pinned connection, is then installed among the cover of wedge of cat ladder fixed bearing by cat ladder hook, loads onto spring cotter, just complete the installation of cat ladder.Version is simple, easy for installation, quick.
