Description
Technical field
The utility model is related to a kind of flat arm dual-fuel engine oil of swing arm, belongs to technical field of engineering machinery.
Background technology
With National Industrial and the development of urban construction, higher requirement, existing tower are proposed to tower crane hanging device
Machine has different advantage and disadvantage.
Movable arm tower crane is that a kind of radius of gyration is small, lifting capacity is big, lifting altitude is high, and width is carried out by controlling the crane arm elevation angle
The derrick crane of change is spent, the deficiency existed is as follows：The luffing time is long, generally for any brachium movable arm tower crane from maximum
Changes in amplitude to minimum radius needs 3 minutes, in some small lifting capacities and the occasion that frequently lifts can have a strong impact on operating efficiency.
Flat arm tower crane is that a kind of crane arm level is fixed, and hang raising suspension hook by dolly moves horizontally realization along crane arm
The derrick crane of luffing, comprising flat-top tower crane, two kinds of structure types of tower top formula tower crane, the deficiency existed is as follows：Returned during operation
Turn radius ratio larger, such as：The flat arm tower crane of 60m brachiums, in 10m amplitudes and 60m amplitude operations, the crane arm radius of gyration is all
60m；The counter-jib of other flat arm tower crane is also longer, and general length is two to three times of movable arm tower crane；Locating by a small margin, it hangs load
Performance is more much smaller than movable arm tower crane.
Therefore, develop it is a can the convenient free switching mode of operation between movable arm type tower crane and flat arm type tower crane
Function and service formula tower crane effectively can preferably adapt to various operating modes, more use requirements can be met, and be user institute
Favor.
The content of the invention
For above-mentioned existing technical problem, the utility model provides a kind of basic boom and tower by movable arm type tower crane
The crane arm feature of top formula tower crane, the new tower crane for the novel concept that movable arm tower crane is combined with tower top formula tower crane function.
To achieve the above object, a kind of flat arm dual-fuel engine oil of swing arm of the utility model offer, including tower top, crane arm, with
And both counter-jibs are connected respectively；Crane arm is provided with flat arm jib lubbing mechanism and mobile arm amplitude mechanism, and its arm root is hinged revolution
Bearing；Its arm end connection swing arm suspension hook 5, and swing arm suspension hook 5 controls the elevation angle of crane arm to change come real by mobile arm amplitude mechanism
Existing luffing motion；It winds up and connects flat arm, one end of swing arm pull bar respectively, and the other end connection tower top of flat arm, swing arm pull bar；
Its lower edge to connect and hang flat arm suspension hook by hoist rope below flat arm dolly, flat arm dolly, and flat arm suspension hook passes through flat arm
Jib lubbing mechanism controls the horizontal position in-migration of flat arm dolly to realize that luffing is moved.
Further, described flat arm brace uses push-and-pull rod or flexible cable.
Further, described counter-jib uses movable arm tower crane counter-jib.
Above-mentioned tower crane structure type is similar to movable arm type tower crane, i.e., be designed to support by movable arm tower crane crane arm lower edge
The form of flat arm carriage walking, and winded up the one or several flat arm brace pin joints of increase in crane arm, rigid drawing can be used
Bar or flexible cable connect tower top with crane arm, to increase the rigidity of crane arm.Also, set at the arm end of crane arm
One swing arm suspension hook, while setting a set of flat arm trolley lifting hook system again in crane arm lower edge, coordinates one arranged on crane arm
Flat arm jib lubbing mechanism is covered, for the luffing motion of the peaceful arm suspension hook of flat arm dolly.
Because this tower crane has two sets of independent tie systems, two sets of changing-breadth systems and two sets of raising suspension hooks, so tool
There are two kinds of mode of operations of flat arm and swing arm, and two kinds of mode of operations can be with free switching.I.e.：
A, under flat arm pattern：Crane arm places level, and flat arm brace stress simultaneously prevents crane arm downwarp, enables flat arm and hang
It is hooked into row and hangs loads, and flat arm suspension hook is realized by moving horizontally for the flat arm dolly of flat arm jib lubbing mechanism control on crane arm
Luffing is moved, and swing arm suspension hook is received to crane arm end and fixed；
B, under swing arm pattern：The passive arm brace pull-up of crane arm is faced upward, and is enabled swing arm suspension hook and is carried out hanging load, passes through swing arm
The jib lubbing mechanism control crane arm elevation angle changes to realize the changes in amplitude of swing arm suspension hook, and flat arm brace relaxes, and flat arm dolly is consolidated
At cargo boom root, flat arm suspension hook is received to flat arm dolly fixed.
Compared with prior art, the utility model merges movable arm tower crane with the function of flat arm tower crane, with following excellent
Point：
1st, this tower crane, which can carry out swing arm operation, can also carry out flat arm operation, two kinds of mode of operations can any switching laws, and
Flat arm suspension hook can be fixed on the position set on crane arm safely with swing arm suspension hook, the mutual not shadow under different work patterns
Ring；
2nd, this tower crane is essentially movable arm tower crane under swing arm pattern, thus have concurrently by a small margin, the big advantage of lifting capacity；By
It can be kicked up in crane arm and the counter-jib radius of gyration is small, therefore have the advantages that operation rotary space is small, while swing arm suspension hook can
To reach higher hoisting height；
3rd, this tower crane is essentially flat arm tower crane, luffing is realized by the walking of flat arm dolly under flat arm pattern, due to
Flat arm tower crane carriage walking speed, therefore have the advantages that operating efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, crane arm, 2, flat arm brace, 3, swing arm pull bar, 4, flat arm dolly, 5, swing arm suspension hook, 6, flat arm suspension hook,
