Abstract
The utility model relates to a steel-concrete composite bridge minor longitudinal beam hoisting device, including the cross bridge to setting up the crossbeam on every row of pier, every crossbeam top surface cross bridge is to setting up a guide rail, has set up two spandrels to between each crossbeam in the same direction as the bridge, and the bottom surface of every spandrel girder corresponds every guide rail and sets up an electronic walking wheel along the guide rail walking, sets up two supporting platform on two spandrels between double-phase adjacent crossbeam, and every supporting platform includes two horizontal poles of welding between two longerons, establishes a volume machine of raising above every supporting platform. The utility model is not limited by the terrain; the small longitudinal beam is lifted by the winch without calling large-scale lifting equipment, so that the construction cost can be effectively reduced.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a longeron installation construction of steel-concrete composite bridge is related to, concretely relates to a hoisting device that is used for promoting the longeron from the underbridge to the installation on the bridge.
Background
The reinforced concrete combined bridge comprises steel cross beams erected on each row of piers in the transverse direction, a plurality of steel longitudinal beams are welded between every two adjacent cross beams in the bridge direction, and concrete bridge panels are laid on the longitudinal beams. In the construction process, after the cross beams are erected, the longitudinal beams need to be lifted to the cross beams one by one from the lower part of the bridge to be welded. At present, large-scale equipment such as a floating crane or a crawler crane is generally adopted to hoist the longitudinal beam in construction. The floating crane or the crawler crane is easily limited by navigation conditions or terrain conditions, inconvenience is brought to construction, and due to the fact that the longitudinal beam is small in size and light in weight, relative cost of large-scale hoisting equipment is too high.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a steel-concrete composite bridge minor longitudinal girder hoisting device is provided, avoids the geological conditions to the restriction of construction to minimize construction cost.
The technical scheme of the utility model as follows:
the utility model provides a little longeron hoisting device of steel-concrete composite bridge which characterized in that: including the cross bridge to setting up the crossbeam on every row of pier, every crossbeam top surface cross bridge is to setting up a guide rail, has set up two spandrels between each crossbeam along the bridge to, and the bottom surface of every spandrel girder corresponds every guide rail and sets up an electric walking wheel along the guide rail walking, sets up two supporting platform between double-phase adjacent crossbeam on two spandrels, and every supporting platform includes two welding horizontal poles between two longerons, establishes a book upward quick-witted on every supporting platform.
The utility model is not limited by the terrain, has strong flexibility and convenient construction; the small longitudinal beam is lifted by the winch without calling large-scale lifting equipment, so that the construction cost can be effectively reduced.
Drawings
FIG. 1 is a side view of the present invention in the direction of the bridge;
fig. 2 is a schematic plan view of the present invention.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses a cross bridge is to setting up crossbeam 2 on every row of pier 1, and 2 top surfaces of every crossbeam cross bridges are to setting up a guide rail 3, and in the same direction as the bridge to set up two spandrels 4 between each crossbeam, and the bottom surface of every spandrel girder corresponds every guide rail and sets up an electric walking wheel 5 along the guide rail walking, sets up two supporting platform between double-phase adjacent crossbeam on two spandrels, and every supporting platform includes that two welds horizontal pole 6 between two longerons, establishes a hoist engine 7 on every supporting platform.
When the utility model is implemented, the beam can be directly a steel beam of the steel-concrete combined beam which is installed in place; the guide rail can adopt the channel-section steel that the opening up, and its ground and crossbeam top surface welding, electronic walking wheel supports in the notch of channel-section steel.
The utility model is used for during the construction, according to the construction environment under the bridge, transport little longeron to under the bridge with ship or vehicle, two hoists 7 carry the both ends of hanging a little longeron 8 through wire rope simultaneously, and the electronic walking wheel of control moves along the guide rail, and when little longeron removed the mounted position below, the hoist engine promoted little longeron mounted position and crossbeam welding.
Claims (2)
1. The utility model provides a little longeron hoisting device of steel-concrete composite bridge which characterized in that: including the cross bridge to setting up the crossbeam on every row of pier, every crossbeam top surface cross bridge is to setting up a guide rail, has set up two spandrels between each crossbeam along the bridge to, and the bottom surface of every spandrel girder corresponds every guide rail and sets up an electric walking wheel along the guide rail walking, sets up two supporting platform between double-phase adjacent crossbeam on two spandrels, and every supporting platform includes two welding horizontal poles between two longerons, establishes a book upward quick-witted on every supporting platform.
