Abstract

The utility model provides a girder disjunctor department walks on stage connecting device, includes two sections or multistage girders, and the fixed walks of side of every section girder, and the length of walking is less than the length of girder, makes the walking form the breach in girder disjunctor department, and the breach department of two walks is fixed to the joint board, and the joint board makes two walks form a whole. Compared with the prior art, the wrench has the technical effects that the notch is arranged at the end part of the walking board, so that an operation space is reserved for the wrench, and convenience is brought to the screwing operation of the wrench. After the main beams are assembled, the notch is repaired, and the use of the walking board is not affected.

Description

Walking board connecting device at main girder disassembly part

Technical Field

The utility model relates to a walking board connecting device at a main beam disassembly position.

Background

At present, the outer side of the main beam of the bridge crane is generally welded with a walking board, for example, patent documents with an authorized bulletin number of CN205892528U and an authorized bulletin date of 2017.01.18.

When the girder is inconvenient to transport due to large span, the girder needs to be disassembled into two or more sections, and the general disassembly part adopts a bolt joint mode. The segmented girders need to be assembled to the installation site. When the on-site girder is assembled, the length of the walking board is equivalent to that of the girder, so that the operation space of the bolt spanner is influenced, the work of screwing the bolt on the spanner is troublesome, the installation quality of the bolt is influenced, and potential safety hazards are brought.

Disclosure of Invention

The utility model aims to solve the technical problems: how to design a walking board connecting device at the disassembly position of the main beam, which is convenient for the assembly of the main beam.

The technical scheme of the utility model is as follows:

the utility model provides a girder disjunctor department walks on stage connecting device, includes two sections or multistage girders, and the fixed walks of side of every section girder, and the length of walking is less than the length of girder, makes the walking form the breach in girder disjunctor department, and the breach department of two walks is fixed to the joint board, and the joint board makes two walks form a whole.

The walking board is fixed with the joint board through bolts.

Compared with the prior art, the wrench has the technical effects that the notch is arranged at the end part of the walking board, so that an operation space is reserved for the wrench, and convenience is brought to the screwing operation of the wrench. After the main beams are assembled, the notch is repaired, and the use of the walking board is not affected.

Drawings

Fig. 1 is a schematic diagram of the present utility model.

FIG. 2 is a schematic diagram of the present utility model.

Fig. 3 is a schematic cross-sectional view at B-B in fig. 2.

Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1-3, a deck connection device for a girder disassembly part comprises two or more sections of girders 10, wherein the sides of each section of girders 10 are fixed with deck 11, the length of each deck 11 is smaller than that of each girder 10, the deck 11 forms a notch 101 at the girder disassembly part (namely, the end part of the girders 10), joint plates 12 are fixed at the notches 101 of the two decks 11, and the joint plates 12 form a whole of the two decks 11.

For convenience of operation, the deck 11 and the joint plate 12 are fixed by bolts 102.

The working principle is as follows:

in the manufacturing process, the main beam walking table 11 and the main beam 10 are fixed into a whole, and then the joint plate 12 is manufactured independently.

In assembly, when two sections of girders are connected, the gap is used as a reserved operation space at the disassembly position of the girders, the bolt joints are fixed by using a spanner, and after the girders are assembled, the gap is repaired by using a joint plate, so that the use of the walking board is not influenced.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.

Claims
