Abstract
The utility model discloses a hoist part, especially a tower crane balance arm. The utility model provides a tower crane balance arm of being convenient for production and transporting, including main leaf, bracing and bluff bit, the main leaf is provided with two and be parallel to each other, the bluff bit is provided with two and parallel arrangement, main leaf and bluff bit formation cuboid structure, the connection can be dismantled between two main leaves to the bluff bit, the connection can be dismantled and lie in two diagonal angles of cuboid structure between two main leaves to the bracing. Owing to adopted main leaf and this kind of piece of bluff bit formula structure to constitute the balance arm, this makes can dismantle the slabbing at the balance arm when transporting, made things convenient for the transportation, can the very easy container of putting into, when putting into production simultaneously, main leaf and bluff bit need not to carry on too many welding, and it produces last standardize equipment, the efficiency that can improve production alone.
Description
Technical field
The utility model relates to a kind of crane parts, especially a kind of balance arm of tower-type crane.
Background technology
Tower crane extensively uses in building operation, and the equilibrium arm of current tower crane is all integral structures, general employing integral solder structure.The equilibrium arm of this structure is comparatively reliable, but but there will be following problem when producing and transport:
Whole welding type equilibrium arm is when producing, and need large-scale frock to ensure the size of welding, production efficiency is lower.
The volume of integral type equilibrium arm own is larger, Shortcomings in transport, the large-scale balance arm of tower-type crane of current use is all superelevation ultra-wide, cost is high in transit, and risk is larger, and such equilibrium arm to carry out Container Transport, this adds cost undoubtedly in long-distance transport.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of balance arm of tower-type crane being convenient to produce and transport.
The utility model solves the balance arm of tower-type crane that its technical matters adopts, comprise main leaf, diagonal brace and bluff bit, described main leaf is provided with two and is parallel to each other, described bluff bit is provided with two and be arranged in parallel, described main leaf and bluff bit form rectangular structure, and described bluff bit is detachably connected between two main leaves; Described diagonal brace to be detachably connected between two main leaves and to be positioned at two diagonal angles of rectangular structure.
Further, described diagonal brace tilts to lay along the length direction of main leaf.
Further, on the length direction of main leaf, the direction of tilt of adjacent two diagonal braces is contrary.
Further, described main leaf comprises stock and pipe link, and described stock is provided with two, and two stocks be arranged in parallel, and pipe link is detachably connected between two stocks.
Further, described pipe link is connected between two stocks by high strength bolt group.
Further, described diagonal brace is connected between two main leaves by high strength bolt group.
Further, also comprise pulley bracket, described pulley bracket is detachably arranged between two main leaves anyhow.
The beneficial effects of the utility model are: owing to have employed main leaf and this slice structure of bluff bit to form equilibrium arm, and this makes can be disassembled into sheet at equilibrium arm when transporting, and facilitates transport, can put into freight container easily; Simultaneously when producing, main leaf and bluff bit are without the need to carrying out too many welding, and its independent production finally carries out normalisation assembling, can improve the efficiency of production.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1,2 and 3, the utility model comprises main leaf 1, diagonal brace 2 and bluff bit 3, and described main leaf 1 is provided with two and is parallel to each other, and described bluff bit 3 is provided with two and be arranged in parallel, described main leaf 1 forms rectangular structure with bluff bit 3, and described bluff bit 3 is detachably connected between two main leaves 1; Described diagonal brace 2 to be detachably connected between two main leaves 1 and to be positioned at two diagonal angles of rectangular structure.Balance arm of tower-type crane is originally as framed structure, and main leaf 1 and bluff bit 3 are also framed structures.Main leaf 1 and bluff bit 3 are spliced into rectangular structure, and diagonal brace 2 is arranged on the diagonal angle of rectangular structure, and rectangular structure can be made so firm; Above-mentioned main leaf 1, bluff bit 3 and diagonal brace 2 are all detouchable parts, can process separately man-hour adding, and when transporting, three is also independently, when deployed, three is assembled into equilibrium arm.Above-mentioned main leaf 1, bluff bit 3 are connected at Nodes by high strength bolt or bearing pin with diagonal brace 2.This detouchable mode more for convenience, decreases welding capacity when producing, and can save transport space when transporting, and reduces traffic cost.This balance arm of tower-type crane has installation, dismounting, maintenance conveniently; Produce the frock used and have certain interchangeability, and the volume that takes up room is little, processing welding efficiency is high; Single chip architecture (main leaf 1 and the bluff bit 3) volume that takes up room is little, is convenient to the container shipping of extra large land.This equilibrium arm is applicable to the equilibrium arm requirement of all kinds of tower crane.
Concrete, described diagonal brace 2 tilts to lay along the length direction of main leaf 1.On the length direction of main leaf 1, the direction of tilt of adjacent two diagonal braces 2 is contrary.Utilize the diagonal brace 2 of inclination, the intensity of balance arm of tower-type crane can be improved by actv., meet the operating needs of tower crane.
Concrete, as shown in Figures 4 and 5, described main leaf 1 comprises stock 11 and pipe link 12, and described stock 11 is provided with two, and two stocks 11 be arranged in parallel, and pipe link 12 is detachably connected between two stocks 11.Like this, stock 11 and pipe link 12 can be utilized to be spliced into main leaf 1, to be conducive to the production of main leaf 1.
As shown in figures 1 and 3, described pipe link 12 is connected between two stocks 11 by high strength bolt group 4.Described diagonal brace 2 is connected between two main leaves 1 by high strength bolt group 4.Strength bolts group 4 can meet the requirement of intensity.
Concrete, also comprise pulley bracket, described pulley bracket is detachably arranged between two main leaves 1 anyhow.Pulley bracket can install pulley, meets the operating needs of equilibrium arm.
