Problems solved by technology
[0002] In the prior art, the load-bearing parts of all bridge erecting machines are steel truss non-prestressed girder structures assembled by Bailey sheets or steel truss beams. Although it can meet the requirements of bridge erection, the bridge erecting machine of this structure The amount of steel used is large, the weight is large, and the cost is relatively high
For example, for a traditional bridge erecting machine with a span of 40 meters, the total amount of steel girders used for the truss girder alone is about 100-130 tons, and the cost of the truss girder is at least 800,000-1 million yuan, which leads to the high manufacturing cost of the bridge erecting machine
Due to the strength of the material and the volume of the bridge erecting machine, there is no precedent in the industry for using other materials to replace steel materials. Therefore, a bridge erecting machine with a simple structure, small volume and a significant reduction in manufacturing costs is needed

Embodiment Construction
[0022] This embodiment is suitable for bridge erection construction operations with a span of 35 meters and a checked weight of less than 140 tons.
[0023] figure 1 It is the front view of the prestressed concrete arch bridge erecting machine according to the present invention. As shown in the figure, the concrete arch bridge erecting machine includes arch ribs 1, tie beams 2, booms 3, beams 4, cross braces 5, and columns 6 , stay cable 7, strut 8, ballast 9, steel rail 10, trolley 11, three groups of supporting legs 12, the traveling steel wheel 13 that supporting leg bottom installs. The arch ribs 1, tie beams 2, columns 6, and struts 8 are two groups, and the two groups of arch ribs 1 are connected by cross braces 5, and the two groups of tie beams 2, columns 6, and struts 8 are connected by cross beams 4 respectively. Arch ribs 1, tie beams 2, beams 4, cross braces 5, columns 6, and struts 8 are cast reinforced concrete components. The specifications are 6Φ15.2 prestres...

The invention discloses a concrete arch bridge erecting machine, which includes a hydraulic system, an electromechanical system, tie beams, beams, struts, weights, rails, beam erecting trolleys, outriggers, walking steel wheels, arch ribs, suspension Rods, columns, cables, the two ends of the arch ribs are rigidly connected with the tie beams to form an arched beam, and the arch ribs and the tie beams are connected by suspenders. connection, the arched beam and the end of the strut away from the column are connected to the top of the column through a cable, the arch ribs, tie beams, beams, columns and struts are reinforced concrete pouring components, and the rails are arranged at the bottom of the tie beam. The concrete arch bridge erecting machine has a simple structure and can greatly save manufacturing and construction costs.
Description
technical field [0001] The invention relates to a bridge erecting machine for erecting bridges, in particular to a concrete arch bridge erecting machine. Background technique [0002] In the prior art, the load-bearing parts of all bridge erecting machines are steel truss non-prestressed girder structures assembled by Bailey sheets or steel truss beams. Although it can meet the requirements of bridge erection, the bridge erecting machine of this structure The amount of steel used is large, the weight is large, and the cost is relatively high. For example, for a traditional bridge erecting machine with a span of 40 meters, the total amount of steel girders used for the truss girder alone is about 100-130 tons, and the cost of the truss girder is at least 800,000 to 1 million yuan, which leads to the high manufacturing cost of the bridge erecting machine. Due to the strength of the material and the volume of the bridge erecting machine, there is no precedent for using other m...
