Description
Technical field
The present invention relates to a kind of high pedestal jib crane, particularly relate to a kind of high pedestal jib crane suspension system.
Background technology
High pedestal jib crane is along with the development of harbour cause gets up.1890, for the first time immutable for amplitude fixed rotatable jib-type crane is contained on operation type half gate seat be across above narrow harbour, become the early stage increasing of port half span winch along with harbour width, gate seat and half span winch develop side by side, and generally adopt pitching jib and level luffing system.After World War II, port span winch develops rapidly and works side by side to same ship for ease of multiple stage hoisting crane, generally have employed the rotary-column type span winch that rotating element is connected with column body, or the rolling bearing type supporting rotaring device that rotating element is connected with gate seat by large bearing, to reduce the tail footpath of rotating element, and have employed the gate seat structure that face (gate seat main body is to the projection on ground) covered by reduction harbour.In evolution, span winch also progressively promotes the use of the places such as the operating condition building berth close with harbour and building site, power station.
As everyone knows, suspension system is the important component part of high pedestal jib crane, at present, the suspension system of existing high pedestal jib crane adopts single jib mostly, like this when hanging picking thing, often needing to coordinate rotating mechanism, Yang Fu mechanism and luffing mechanism to carry out common operational and goods being hung the place got and specify.Complex operation, inefficiency.
Summary of the invention
The object of the present invention is to provide a kind of high pedestal jib crane suspension system, it has simple and quick and that handling efficiency is high feature, to solve the problems referred to above that in prior art, high pedestal jib crane suspension system exists.
For reaching this object, the present invention by the following technical solutions:
A kind of high pedestal jib crane suspension system, it comprises turntable, upper rotary column, large pull bar, jib and trunk beam, described turntable is arranged on the door frame of hoisting crane rotationally, described upper rotary column is arranged on described turntable, wherein, one end of described large pull bar is articulated with the upper end of described upper rotary column, one end of the hinged described trunk beam of the other end, the other end of described trunk beam stretches out lifting steel wire connecting shackle, one end of described jib is articulated with on described turntable, the other end is articulated with the middle part of described trunk beam, lower link bar is hinged with between described jib and described large pull bar, one end that described lower link bar is connected with described large pull bar is provided with balancing device, the hinged place of described lower link bar and described jib is connected with driving tooth bar, coordinate and drive tooth bar to be provided with driven wheel on described upper rotary column, described driven wheel is driven by retarder by drive motor.
Especially, the both sides of described large pull bar, jib and trunk beam are provided with guard rail, and the hinged place of described large pull bar and trunk beam, jib and the hinged place of trunk beam and the outer end of trunk beam are provided with the platform being with guard rail.
Especially, described balancing device comprises equilibrium arm and clump weight, and one end of described equilibrium arm connects lower link bar, and is articulated with the hinged place of described large pull bar and upper rotary column in the middle part of it, and described clump weight is installed on the other end of described equilibrium arm.
Especially, the both sides of the end face of described equilibrium arm are provided with guard rail.
Beneficial effect of the present invention is, compared with prior art described high pedestal jib crane suspension system moves by driving rack drives cantilever, thus drives trunk beam and large pull bar entirety to do folding movement, thus operates when simplifying lift cargo, not only simple and quick, improve handling efficiency; And it is reliable stable.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the high pedestal jib crane suspension system that the specific embodiment of the invention 1 provides.
In the present embodiment, a kind of high pedestal jib crane suspension system comprises turntable 1, upper rotary column 2, large pull bar 3, jib 4 and trunk beam 5, described turntable 1 is arranged on the door frame of hoisting crane rotationally, described upper rotary column 2 is arranged on described turntable 1, wherein, one end of described large pull bar 3 is articulated with the upper end of described upper rotary column 2, one end of the hinged described trunk beam 5 of the other end, the other end of described trunk beam 5 stretches out lifting steel wire connecting shackle 6, one end of described jib 4 is articulated with on described turntable 1, the other end is articulated with the middle part of described trunk beam 5, lower link bar 7 is hinged with between described jib 4 and described large pull bar 3, one end that described lower link bar 7 is connected with described large pull bar 3 is provided with balancing device, described lower link bar 7 is connected with the hinged place of described jib 4 and drives tooth bar 8, coordinate and drive tooth bar 8 to be provided with driven wheel on described upper rotary column 2, described driven wheel is driven by retarder by drive motor.
