Abstract
The utility model discloses a kind of derrick crane folding Undercarriage structure, including whole beam and two Half Beams, and two Half Beams are arranged symmetrically in the both sides of whole beam, connected between Half Beam and whole beam by bearing pin；By coordinating the use of bearing pin, Half Beam is set to be in the state for folding or deploying；When underframe works, whole beam is assembled into deployed condition with Half Beam；When transport protection, whole beam is assembled into folded state with Half Beam.The utility model flexible structure, Half Beam can be as needed, is assembled into different states.The utilization rate in space can be effectively improved during in folded state；Underframe is in off position when transport protection, can fold reduction space, transport of being more convenient for；Maintenance is convenient, improves the processing, transport and performance of product.
Description
Technical field
The utility model is related to a kind of derrick crane folding Undercarriage structure, belongs to derrick crane underframe technology neck
Domain.
Background technology
Undercarriage structure is often used when derrick crane is connected with ground base, as shown in figure 1, underframe 4 is fixed
It is used for the installation of tower body in ground base.Because underframe and tower body are connected, so underframe will typically be made big.It is at present to adopt more
With welding Integral underframe, this processing to underframe and transport have higher requirement.Existing Undercarriage structure is as shown in Fig. 2 bottom
Frame is welded by whole beam 1 and two Half Beams 2, and two Half Beams 2 are arranged symmetrically in the both sides of whole beam 1.This structure exists as follows
It is not enough：
1st, structure is fixed, and underframe space-consuming is big.Underframe can not be folded, and space-consuming is larger, low space utilization.
2nd, transport protection is unfavorable.Due to underframe formation structure of right angle tyoe, in transport, fixed protection engaged position is also big, no
Beneficial to fixed and protection.
3rd, inconvenient maintenance, because entirety is one relatively cumbersome if necessary to maintenance adjustment, renewal part needs integral replacing.
The content of the invention
The problem of existing for above-mentioned prior art, the utility model provides a kind of derrick crane folding underframe knot
Structure, flexible structure, Half Beam can be as needed, is assembled into different states；Fold, deploy when using during transport.
To achieve these goals, a kind of derrick crane folding Undercarriage structure that the utility model is used, including
Whole beam and two Half Beams, two Half Beams are arranged symmetrically in the both sides of whole beam, connected between Half Beam and whole beam by bearing pin；By with
The use of dowel pin axle, makes Half Beam be in the state for folding or deploying；When underframe works, whole beam is assembled into expansion with Half Beam
State；When transport protection, whole beam is assembled into folded state with Half Beam.
Preferably, each Half Beam is connected by four bearing pins with whole beam, and the line of four bearing pins is square.
Preferably, the end of the Half Beam is provided with buckle, the corresponding position of whole beam be provided be clasped use it is recessed
Groove, when whole beam and Half Beam are assembled into folded state, the buckle on Half Beam is stuck in whole beam groove.
Compared with prior art, Half Beam and whole beam are connected using bearing pin in the utility model, whole beam and Half Beam point during processing
Do not process, then assembled with bearing pin, folded state can be used during transport protection, the space taken is saved.It can be used when actually used
Deployed condition, is conveniently installed and used, and improves the performance of product.Generally speaking, have the following advantages that：
1st, flexible structure, Half Beam can be as needed, is assembled into different states.It can be effectively improved during in folded state
The utilization rate in space.
2nd, protection is readily transported, underframe is in off position when transport protection, reduction space can be folded, more just
In transport.
3rd, repair convenient, because underframe assembling is integral, changed for maintenance renewal part just for damaged part, maintenance is just
It is prompt.
4th, improved by structure, lift processing, transport and the performance of product.
Brief description of the drawings
Fig. 1 is the scheme of installation of existing underframe；
Fig. 2 is the structural representation of existing underframe；
Fig. 3 is structural representation of the present utility model；
Fig. 4 is folded state diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 3 and Figure 4, a kind of derrick crane folding Undercarriage structure, including whole beam 1 and two Half Beams 2, two
Individual Half Beam 2 is arranged symmetrically in the both sides of whole beam 1, is connected between Half Beam 2 and whole beam 1 by bearing pin 3；By coordinating making for bearing pin 3
With, make Half Beam 2 be in fold or expansion state；When underframe works, whole beam 1 is assembled into deployed condition with Half Beam 2；
When transport protection, whole beam 1 is assembled into folded state with Half Beam 2.Whole beam and Half Beam are processed respectively during processing, then use bearing pin group
Dress, can be folded as fulcrum using the bearing pin connected during transport protection, save the space taken.Expansion can be used when actually used
State, is conveniently installed and used, and improves the performance of product.
Preferably, each Half Beam 2 is connected by four bearing pins with whole beam 1, and the line of four bearing pins is square.I.e. whole beam 1
Using eight bearing pin connections between two Half Beams 2, coordinate the use of bearing pin, can be in Half Beam and fold and deployed condition, its
Folded state is as shown in Figure 4.
Preferably, the end of the Half Beam 2 is provided with buckle, and the corresponding position of whole beam 1 is provided with being clasped what is used
Groove, when whole beam 1 and Half Beam 2 are assembled into folded state, the buckle on Half Beam 2 is stuck in the whole groove of beam 1.Buckle and groove
Set, but folded state is more firm, transport protection of being more convenient for.
From said structure, the utility model makes underframe to be made with piecemeal by Novel structure, overall package, uses
Bearing pin is connected, and it is fulcrum folding that can connect bearing pin, reaches the purpose be easy to process and transported, and improve the usability of product
Energy.
