Abstract
The invention relates to a special boom head device of a crawler crane for a wind generating set, which is used for hoisting a wind generating set. The device comprises a transition section and a special boom head, wherein the transition section is a space truss, the back end is connected with the middle section of a main arm, the upper part of the front end is hinged with the back end of the special boom head by two hinges, and the lower part is provided with two pin shafts; the lower part of the back end of the special boom head is provided with two fork heads which correspond to the pin shafts on the transition section; the transition section is provided with a main boom cable connecting lug and a guide pulley rack; the front end of the special boom head is provided with a hoisting pulley block; the guide pulley rack is hinged on the transition section, and can be turned over inside the transition section when being assembled; and the lower part of the front end of the special boom head is provided with a sliding roller wheel which prevents the special boom head from being damaged by falling to the ground when being assembled. Compared with the main boom and the fixed auxiliary boom for hoisting, the invention has the advantages of reliable operation, simple and practical structure and light weight, improves the hoisting capability of the complete machine, decreases the installing steps, and raises the production efficiency.
Description
One. technical field
The present invention relates to crawler crane lifting arm head device, especially for the special-purpose arm head device of hoisting large-size wind power equipment.
Two. background technology
At present, use main equipments such as crawler crane lifting wind power generating set, generally the practice of Cai Yonging is to use principal arm lifting or fixedly auxiliary lifting.Use principal arm lifting mode when lifting than big article, suspended object spare and jib scratching phenomenon appear easily, thereby must increase operating radius, increase jib length, because wind-powered electricity generation lifting operating mode all is to adopt the overlength jib, the unit assembling of ship machinery ability is determined by complete machine stability, increases operating radius and increases jib length and cut down the unit assembling of ship machinery ability significantly; Use fixedly auxiliary lifting mode, when jib is installed, parts such as auxiliary, strut, front and back drag-line need be installed on the principal arm head, step is loaded down with trivial details especially, in the hoisting process, unfavorable factors such as the weight of optional features such as strut, drag-line, additional dynamic load, wind area have a negative impact to the unit assembling of ship machinery ability.
Three. summary of the invention
The purpose of this invention is to provide a kind of special boom head device of crawler crane for wind generating set, with the problem of solve using the principal arm lifting or fixedly producing during auxiliary lifting wind power generating set, thereby save the set-up time, improve the lifting ability, reliable and stable work is enhanced productivity.
The technical solution used in the present invention is: special boom head device of crawler crane for wind generating set is made up of transition segment and special-purpose arm head two parts, transition segment is a space truss, the rear end is connected with segmentum intercalaris in the principal arm, the top of front end is by two hinges and special-purpose arm head upper articulation, and two bearing pins are arranged at the bottom; Two jaws are arranged at the bottom of special-purpose arm head and transition segment coupling end, and this two jaw is corresponding with the bearing pin on the transition segment.Principal arm cable connecting lug and guide pulley rack are arranged above the transition segment; The front end of special-purpose arm head is installed hoisting pulley block.Guide pulley rack is hinged on the transition segment, can be turned to transition segment inside when assembling.The rolling roller is installed in the front end bottom of special-purpose arm head, when assembling special-purpose arm head is landed and injury-free.
The present invention is reasonable in design, and reliable operation is simple and practical, and is in light weight.The principal arm lifting is used in contrast, when hanging height, identical operation radius, the same object of lifting, has avoided the scratching phenomenon of suspended object spare with principal arm identical, also needn't cut down the unit assembling of ship machinery ability because of increasing operating radius and increasing jib length; Fixedly auxiliary lifting is used in contrast, has saved the step that connects auxiliary, strut, strut front and back drag-line, has eliminated again by the influence of unfavorable factors such as the weight of optional features such as strut, drag-line, additional dynamic load, wind area to the unit assembling of ship machinery ability.Simultaneously can reduce installation steps, enhance productivity.Being particularly suitable for crawler crane uses.

Five. the specific embodiment
In the prior art, when using principal arm hoisting large-size object, be in jib, to connect arm head 1 on the segmentum intercalaris 2, be easy to generate suspended object spare and lifting jib scratching phenomenon in the work, can cut down the unit assembling of ship machinery ability significantly and increase operating radius and increase jib length; Adopt fixedly auxiliary lifting, be on arm head 1, to connect auxiliary 3, parts such as strut 5, front and back drag- line 4,6 also will be installed, step is loaded down with trivial details especially, in the hoisting process, unfavorable factors such as the weight of optional features such as strut 5, drag- line 4,6, additional dynamic load, wind area have a negative impact to the unit assembling of ship machinery ability.
Special boom head device of crawler crane for wind generating set of the present invention is made up of transition segment 7 and special-purpose arm head 8, transition segment 7 adopts space truss high strength steel pipe welded structure, the rear end is adopted and is forged segmentum intercalaris 2 in the jib joint connection principal arm, front end adopts steel plate splicing jib joint to connect the wind-powered electricity generation unit and lifts special-purpose arm head 8, and principal arm cable connecting lug 7-1 and guide pulley rack 7-2 are arranged above the middle segmentum intercalaris 7; Wind-powered electricity generation lifts special-purpose arm head 8 and adopts space truss high strength steel pipe welded structure, and leading section is installed hoisting pulley block 8-3 and rolling roller 8-4;
These two parts rely on bearing pin to connect by four pairs of steel plate splicing jib joints, two pairs of jib joints of upper side 7-3,8-1 adopt bearing pin hinged, two pairs of jib joints of downside adopt V shape joint 7-4,8-2 to connect, wherein welded bearing pin in advance between the ears plate of two joint 7-4 of transition segment front end downside, two joints of the special-purpose arm head rear downside of wind-powered electricity generation are fork-shaped, this connection mode can make the special-purpose arm head of wind-powered electricity generation in the two pairs of V shape jointings disengagements in side at present of the whole jib of assembling, transition segment is landed, be convenient to connect work such as jib, wire rope handling; Two pairs of V shape jointings align automatically after playing arm, have saved the step of wearing bearing pin; Guide pulley rack 7-2 on the transition segment can fold and change transition segment inside over to, can reduce the transported in parts height like this when transportation; The rolling roller is positioned at the anterior 8-4 of the special-purpose arm head of wind-powered electricity generation, when playing arm and falling arm, the special-purpose arm head of wind-powered electricity generation is slided on the ground, has not only avoided the hoisting pulley block of using the trouble of auxiliary hoist but also can protecting the arm head leading section.
