Abstract
The utility model relates to a multifunctional jib head device installed at the top of a large-tonnage crawler crane jib, which is characterized in that high-strength steel plates are welded into a box-shaped body with a symmetrical multi-lug plate structure, and connecting holes for connecting a pulley block are arranged on lug plates symmetrically arranged at the front end; lug plats for installing a guide wheel set and lug plates for connecting the back supporting rack of a tower jib are respectively and symmetrically arranged at the back of the box-shaped body, and connecting holes for connecting an anti-leaning rod, connecting holes for connecting the tower jib, lug plates for connecting the small anti-leaning rod of the tower jib and lug plats for connecting the front supporting rackof the tower jib are respectively and symmetrically arranged at the upper parts of the two sides of the box-shaped body; and four connecting holes below the box-shaped body are connected with a transition jib. The utility model has reasonable design and ingenious conception. The large-tonnage crawler crane uses the jib head device, so that the utility model has the operating function of connecting four jibs, is suitable for four different working conditions, can reduce the number of the replaced and adjusted components and time, reduces production cost and improves production efficiency.
Description
One, technical field
The utility model relates to a kind of multi-functional arm head device that is installed in the crawler crane boom top, can realize four kinds of jib combinations and be connected fast, is specially adapted to the large-tonnage crawler crane and uses.
Two, background technology
At present, the main elevator boom rack headset structure of most large-tonnage crawler cranes is structure a kind of and top arms joint one substantially, can only be connected with fixed auxiliary.At this Heavy Weight of tower auxiliary, the use of bulky jib can only change the whole joint arm of going up, and changes the transition jib, changes the special arm head that is connected with tower auxiliary again, and the associated components of crawler crane is increased, and causes manufacturing cost to strengthen.In addition, long from beginning to change to the concluding time, waste time and energy, also influence is used.
Three, summary of the invention
The purpose of this utility model provides a kind of multi-functional arm head device of large-tonnage crawler crane, to realize the more than enough usefulness of a kind of arm head energy, reduces the manufacturing cost of crawler crane, improves service efficiency.
The utility model---multi-functional arm head device adopts high tensile steel plate to be welded into the box-like body of symmetrically arranged many otic placodes structure, and the symmetrically arranged otic placode of its front end is provided with the connecting bore that connects assembly pulley, is used to install the gin wheel group; The box-like body rear portion be symmetrical arranged respectively otic placode that the guiding wheels are installed and with tower arm back pole-bracket bonded assembly otic placode, be equipped with connecting bore on each otic placode; The top of its box-like body two sides be symmetrical arranged respectively with sway bar or extension arm pull bar bonded assembly connecting bore and with tower arm or fixing auxiliary bonded assembly connecting bore, also be provided with simultaneously with tower arm little sway bar bonded assembly otic placode and with tower arm front pole-bracket or fixedly auxiliary support or extension arm depression bar bonded assembly otic placode, be attached thereto by the connecting bore on the otic placode; Below its box-like body, be provided with 4 connecting bores, be used for and being connected of transition arm.In addition, also be arranged with at the rear portion of its box-like body and principal arm arm-tie bonded assembly connecting bore.To satisfy multi-functional arm head Unit Installation needs.
The utility model is reasonable in design, is skillfully constructed.The large-tonnage crawler crane uses this arm head device, has the operation function that can connect four kinds of jibs, is applicable to four kinds of different operation operating modes, can reduce the quantity and the time of replacing and adjustment component, has reduced productive costs, has improved production efficiency.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
As shown in the figure, it is to be welded with high tensile steel plate that multi-functional arm head device adopts many otic placodes box-like body 2 of symmetrical structure, on the symmetrically arranged otic placode 1 of its front end connecting bore is arranged, and is used to install the assembly pulley 11 of reusing.On the symmetrically arranged otic placode 5 in box-like body 2 rear portions connecting bore is arranged, be used for installing guiding wheels 12.Box-like body 2 rear portions also are symmetrical arranged otic placode 6, and the tower arm back pole-bracket of crawler crane is connected with this arm head device by the connecting bore on the otic placode 6.Two upper lateral parts of box-like body 2, symmetrically arranged connecting bore 7 are used for being connected with the sway bar or the extension arm pull bar of crawler crane; Symmetrically arranged connecting bore 10 is used for and the tower arm of crawler crane or fixing being connected of auxiliary; Connecting bore on the symmetrically arranged otic placode 8 is used for crawler crane tower arm front pole-bracket or fixedly auxiliary support or extension arm depression bar are connected; Symmetrically arranged otic placode 9 is the ears plate, and its connecting bore is used for and being connected of the little sway bar of tower arm of crawler crane.Below box-like body 2,4 connecting bores 3 are used for being connected with the transition arm of crawler crane.On box-like body 2, be symmetrically arranged with connecting bore 4, be used for during installation being connected with the principal arm arm-tie of crawler crane.
The utility model is reasonable in design, can replace two kinds of arm head devices that are used for four kinds of operating modes (principal arm lifting operating mode, principal arm extension arm operating mode, fixedly auxiliary operating mode and tower auxiliary operating mode) at present.Crawler crane is connected with this arm head device by transition arm, can be used in described four kinds of operating modes, significantly reduces the quantity and the time of replacing and adjustment component, is specially adapted to use on the large-tonnage crawler crane.
