Abstract
A kind of multistage interconnection system crane girder, including more than two beam elements are the utility model is related to, the end face of two neighboring beam element is respectively arranged with public plate and motherboard, and the public affairs plate and motherboard are connected.The utility model multistage interconnection system crane girder, the mode being nested using rim of the mouth connects multiple beam element combinations, this connection mode is mainly used for the crane of large span, overlength and interim building site, the replacement and dismounting transport in convenience in transport and interim building site, big space is not take up, the shifting dress inconvenience for solving the problems, such as the transport problem of overlength crane and interim building site, adds work efficiency, the utility model has good economic value and social benefit, is worth of widely use.
Description
Technical field
A kind of multistage interconnection system crane girder is the utility model is related to, belongs to crane technical field.
Background technology
Control of the country to highway overlength overload transportation in recent years, causes the highway of Crane Industry overlength crane
Transport becomes a great problem, therefore it is particularly important that progress technological improvement design in time.
For crane as heavy-duty machinery, quality and space structure are all larger, some of goliath girder length across
Spend very big, few then more than ten meters, at most tens meters.Since crane girder length is larger, select general truck transport relatively difficult,
Special vehicle is typically chosen in industry to transport for long-distance.But the length of goliath girder does not meet National Highway public affairs sometimes
The transport requirement on road, this has resulted in the difficulty in transport.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of multistage interconnection system crane girder, lifting owner
Beam has abandoned the integral structure pattern of girder in the past, and girder is changed to the combined structural type of dismountable multiple beam elements
Formula, makes it in transportational process, is detachably transported into the beam element of multiple short lengths, after arriving at, then will be multiple
Beam element is combined into a complete girder.
The technical solution of the utility model is as follows：
A kind of multistage interconnection system crane girder, including more than two beam elements, the end face point of two neighboring beam element
Public plate and motherboard are not provided with, and the public affairs plate and motherboard are connected.
Preferably, the crane girder includes 3-8 beam element.
Preferably, butt hole is offered on the motherboard, the surrounding of butt hole is provided with screw hole.
Preferably, side is equipped with docking block on the public plate, and the surrounding for docking block is provided with screw hole, and the docking block is inserted
Enter butt hole and realize mating connection.
Preferably, the public plate and motherboard are achieved a fixed connection by bolt through screw hole.
Preferably, the bottom of the motherboard and public plate is respectively arranged with T-shaped mouth, I-steel is inserted with T-shaped mouth, I-steel leads to
The connecting plate for crossing both sides is fixedly connected.
The beneficial effects of the utility model are：
The utility model multistage interconnection system crane girder, the mode being nested using rim of the mouth make multiple beam element combination connections
Get up, this connection mode is mainly used for the crane of large span, overlength and interim building site, the replacement in convenience in transport and interim building site
And dismounting transport, big space is not take up, the shifting dress inconvenience for solving the problems, such as the transport problem of overlength crane and interim building site,
Work efficiency is added, the utility model has good economic value and social benefit, is worth of widely use.

Embodiment
The utility model is described further by way of example and in conjunction with the accompanying drawings, but not limited to this.
Embodiment 1：
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of multistage interconnection system crane girder, including more than two beams
Unit 1, the present embodiment middle girder are made of 3 beam elements 1, and the end face of two neighboring beam element 1 is respectively arranged with male plate 3 and mother
Plate 2, public plate 3 and motherboard 2 are connected.
Public plate 3 and motherboard 2 select high-strength steel sheet, and the thickness of high-strength steel sheet is set according to span, the tonnage of crane
Meter uses.
Wherein, butt hole 6 is offered on motherboard 2, butt hole 6 is rectangular opening, and the surrounding of butt hole 6 is provided with screw hole 5.
Side is equipped with docking block 7 on public plate 3, and the shape of docking block 7 is engaged with rectangular opening, and the surrounding of docking block 7 is provided with screw hole
(not shown), docking block 7 are inserted into butt hole 6 and realize mating connection.Public plate 3 and motherboard 2 are real through screw hole 5 by bolt
Now it is fixedly connected.
In addition, the bottom of motherboard 2 and public plate 3 is respectively arranged with T-shaped mouth 8, I-steel is inserted with T-shaped mouth 8, I-steel can
Bearing capacity is improved, when public plate 3 and motherboard 2 are connected, connection that the I-steel of two neighboring 1 bottom of beam element passes through both sides
Plate 4 is fixedly connected, and two side connecting plates 4 are equipped with screw hole, and two side connecting plates 4 run through I-shaped by dormant bolt through screw hole
Adjacent I-steel is integrally connected by steel.
Embodiment 2：
A kind of multistage interconnection system crane girder, as described in Example 1, its difference is structure：Crane girder
It is made of 8 beam elements 1.Different crane girders, the quantity of disconnecting beam element is designed according to its length, weight, tonnage.
