Description

Three-beam crane bridge

Technical Field

The utility model relates to a hoisting equipment technical field especially indicates a three-beam crane span structure.

Background

The cranes used in common industrial plants are usually single-beam or double-beam bridge cranes, and these cranes usually run directly on the crane beam rails of the plant, so that the need for material handling in single-span plants can only be met, and the transverse cross-span handling of materials in multi-span plants cannot be realized.

In general, to realize the transverse cross-span transportation of materials, a ground track is laid in an adjacent cross workshop and a floor vehicle is arranged for inversion, and the defects of the method are as follows: laying ground tracks in adjacent bay plants increases costs; need dispose the terrace car to carry out a lot of flip-chip to the material that grows up, work efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model provides a three-beam crane bridge has solved among the prior art and can't realize that the material transversely crosses the problem of striding the transport in the workshop of striding more.

The technical scheme of the utility model is realized like this:

a three-beam crane span structure, comprising: the bearing beam is connected with the horizontal supports through a connecting plate, and two ends of each auxiliary beam are connected with the end beams through hinged seats respectively; and each end beam is provided with a driving mechanism for driving crane wheels, and the crane wheels are positioned on the track of the crane beam.

Preferably, the load-bearing beam is a load-bearing beam made of section steel beams.

Preferably, the driving mechanism is a motor and a reduction gearbox, and the output end of the driving mechanism is connected with a rotating shaft of the crane wheel.

The utility model discloses an realize the principle as follows:

the bearing beam is hung below the auxiliary beam through the horizontal support and is lower than the lower plane of the crane beam of the plant, so that the crane trolley can run on the bearing beam along the width direction of the plant; through the driving mechanism on the end beam, the crane trolley can also run along the length direction of the workshop on the track of the crane beam.

In addition, through the configuration of the rail passing device, the bearing beams of the crane bridge frame of the adjacent span workshop are connected with each other, and the crane can also carry materials in a multi-span workshop in a crossing manner.

The utility model has the advantages that:

through the structure that sets up auxiliary beam and carrier bar, can satisfy the use in the workshop of singly striding, also can satisfy the workshop of striding more and stride the use. The material cross-span transportation is realized by using the crane, a ground track does not need to be laid in an adjacent span workshop, and a terrace vehicle does not need to be purchased, so that the cost is saved; the transportation of striding to growing up the material reduces the flip-chip number of times, improves production efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As can be seen from the embodiments shown in fig. 1-3, the present invention provides a three-beam crane bridge, comprising: the supporting device comprises two auxiliary beams 1, a bearing beam 2, a plurality of horizontal supports 3 and four end beams 4, wherein two ends of each horizontal support 3 are respectively connected with the two auxiliary beams 1 through connecting seats 7, the bearing beam 2 is connected with the horizontal supports 3 through connecting plates 8, and two ends of each auxiliary beam 1 are respectively connected with the end beams 4 through hinged seats 5; each end beam 4 is provided with a driving mechanism 6 for driving crane wheels which are positioned on the track of the crane beam 9.

The carrier bar 2 is made of a section steel beam.

The driving mechanism 6 is a motor and a reduction gearbox, and the output end of the driving mechanism 6 is connected with a rotating shaft of a crane wheel.

The bridge frame of the three-beam crane has the following realization principle:

the bearing beam 2 is hung below the auxiliary beam 1 through the horizontal support 3 and is lower than the lower plane position of a crane beam 9 of the plant, so that the crane trolley can run on the bearing beam 2 along the width direction of the plant; the driving mechanism 6 on the end beam 4 enables the crane trolley to run along the length direction of the workshop on the track of the crane beam 9. Therefore, the utility model discloses can satisfy the material handling demand of trolley horizontal and two vertical directions in the factory building.
