Dual-drive device and method for automatic poling

Abstract

The invention discloses a dual-drive device for automatic poling. The dual-drive device comprises a stand, a drive mechanism and a steel fixture, and is characterized by comprising an upper drive wheel and a lower drive wheel which are vertically opposite and axially located on the same perpendicular face, the middle of the upper drive wheel and the middle of the lower drive wheel are each provided with a concave arc, the two concave arcs which are vertically opposite are used for containing and clamping a rubber bar, the drive motor drives the upper drive wheel and the lower drive wheel to rotate in opposite directions at the same time, the drive mechanism comprises a drive shaft, labor intensity can be reduced, lateral slipping is avoided, and driving is powerful.

Description

Technical field [0001] The invention belongs to the technical field of prefabricated bridge construction equipment, and particularly relates to a dual-drive device with automatic pipe piercing. Background technique [0002] During the construction of the precast bridge, the prestressed tension channel can be drawn into a hole with a rubber tube for subsequent stranding and prestressing. If the linearity of the rubber tube is not smooth during the installation process, it will be prestressed. Cause a lot of losses. At present, in the construction of bridge engineering, the installation of the hole-forming rubber rods in the prefabricated beam tunnels mainly adopts manual penetration installation method, that is, the hole-forming rubber pipes are manually transported to the two ends of the steel frame, using one person to guide, and 8-10 people are required to manually The rubber tube penetrates into the tunnel. This method has disadvantages such as high labor intensity, low ergon...

Problems solved by technology

[0002] During the construction of prefabricated bridges, rubber tubes can be used to pull out the prestressed tension channels to form holes for subsequent steel strands to be threaded and prestressed. If the rubber tubes are not linearly smooth during installation, the prestressed cause great loss

At present, in the construction of bridge engineering, the installation of prefabricated beam hole hole-forming rubber rods mainly adopts the manual penetration installation method, that is, the hole-forming rubber tubes are manually transported to the two ends of the steel skeleton, guided by one person, and 8 to 10 people are required to manually install the holes. The rubber tube is penetrated into the channel, which has the disadvantages of high labor intensity, low work efficiency index, and the need to build a working platform for the high-level channel, which is unsafe to operate.

[0003] The Chinese patent announcement number is 204982667 and the U application number is 201520425379.0, which discloses a pipe threading machine including a support, a plurality of rollers, two moving rails, a lifting motor, a lifting frame, a mounting frame, a steel wire rope, a pressing motor, and a plurality of transmission sleeves Sleeve, connecting sleeve, transmission motor, motor support plate, sleeve fixing plate and lead screw, the inventor considered that the clamping force of the transmission sleeve is insufficient, and increased the number and set up a plurality of them, but the driven sleeve is only passive Rotation, the overall driving force is insufficient, and there is still the problem that the rubber rod slips laterally from the two drive rollers
