Description

Installation device for bridge truss

Technical Field

The utility model relates to a bridge construction technical field especially relates to an installation device for bridge truss.

Background

In the bridge construction process, the installation of the truss is an important component, and the installation is carried out by using a crane in the prior art, so the method has the following defects that the construction cost is economically improved by using the crane for installation, the crane occupies a large space and is difficult to transport, and the operation of the crane is complex.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, it provides a device that is arranged in the bridge not to use the loop wheel machine to accomplish the truss installation to solve not enough that prior art exists.

The utility model discloses a technical scheme be a dismouting device that is arranged in bridge truss, be used for supporting including the girder, with pier shaft anchor setting the support of girder, the girder is equipped with the equipment of lifting by crane that is used for lifting by crane the truss respectively, it slides along the girder to lift by crane equipment and sets up, the girder is located the top of support, the support sets up with the girder is fixed.

The support includes the base, the upper and lower both ends of base have set firmly first backup pad, second backup pad respectively, the girder is located the top of first backup pad, the upper and lower both sides of girder have welded respectively and have set firmly first backing plate, second backing plate, thereby the dead lever stretches out the hole site that passes second backup pad, first backup pad, second backing plate, first backing plate from the pier shaft and links to each other girder and support are fixed continuous with the nut screw.

The girder is two I-shaped steel that arrange side by side.

The lifting equipment is an electric hoist.

The quantity of dead lever is four, the base is located the center of four dead levers.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the utility model discloses compare in with the quick-witted installation truss of hoist, area is little, convenient operation, convenient transportation.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a partial enlarged view of the position a of the present invention.

Detailed Description

The present invention will be further described by way of examples with reference to the accompanying drawings.

As shown in fig. 1 to 2, the installation device for a bridge truss according to the present embodiment includes a main beam 1 and a support 2 anchored to a pier body 5 and used for supporting the main beam 1, wherein the main beam 1 is respectively provided with a hoisting device 4 for hoisting the truss 3, the hoisting device 4 is slidably disposed along the main beam 1, the main beam 1 is located above the support 2, and the support 2 and the main beam 1 are fixedly disposed; the main beam 1 is two I-shaped steels arranged side by side; the hoisting equipment 4 is an electric hoist. The utility model fixes the main beam 1 on the pier body 5 through the connection of the support 2, moves along the main beam 1 through the hoisting equipment 4 in the horizontal direction to drive the truss to move to a proper position, and the hoisting equipment 4 moves the truss to a proper position in the vertical direction, thereby realizing the installation of the truss 3; the embodiment replaces a crane to install the truss, and has the advantages of small floor area, convenience in operation, convenience in transportation and the like.

This embodiment support 2 includes base 21, first backup pad 22, second backup pad 23 have set firmly respectively at base 21's upper and lower both ends, girder 1 is located first backup pad 22's top, girder 1's upper and lower both sides welding respectively has set firmly first backing plate 11, second backing plate 12, thereby dead lever 6 stretches out from pier shaft 5 and passes second backup pad 23, first backup pad 22, second backing plate 12, the hole site of first backing plate 11 and nut 7 screw thread link to each other with girder 1 and support 2 are fixed continuous. The number of the fixing rods 6 is four, and the base 21 is positioned at the center of the four fixing rods 6. The main beam 1 and the support 2 are fixedly connected by the fixing rod 6 and the nut 7.
