Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of supporting components, in particular to a blanking support device for slow-bonding prestressed tendons. Background Art
[0002] The production of a single slow-bonding prestressed steel bar should adopt the extrusion molding process and be produced by a specialized processing plant. The coating layer and the production of the sheath should be completed continuously at one time, and the coating layer should completely fill the annular space between the prestressed steel bar and the sheath. The slow-bonding prestressed steel bar should be fully inspected before use. After the prestressed steel bar is unfolded, it should be smooth and no dead bend should occur. The arc height should not exceed 25mm within 1m. The transverse ribs of the outer sheath should be uniform, and the end of the slow-bonding prestressed steel strand should be blocked to prevent the outflow of the slow-setting adhesive. When the slow-bonding prestressed steel strand is partially damaged, it should be repaired with polyethylene tape or hot melt glue stick. If the continuous length of damage within 1m exceeds 100mm, it must be replaced. Therefore, special attention should be paid to the unloading, stacking, unloading and transportation of the slow-bonding prestressed steel bar to avoid dragging the slow-bonding prestressed steel bar during the conventional unloading process. In the face of this problem, it is urgent to design a stacking device to minimize the wear of the slow-bonding prestressed steel bar. Utility Model Content
[0003] In order to overcome the technical defect that the slow-bonding prestressed tendons are easily worn when they are manually dragged for unloading, the utility model provides a unloading support device for the slow-bonding prestressed tendons.
[0004] The utility model provides a material unloading support device for slow-bonding prestressed tendons, comprising a support base, multiple support shafts and a reduction motor, wherein both ends of the support shafts are rotatably connected to the support base through shaft brackets, wherein one support shaft is connected to the reduction motor through a coupling, and multiple support shafts are connected through belt transmission, at least one intermediate roller is installed on the support base between adjacent support shafts, the intermediate roller is arranged on the support base through a connecting seat, and an end roller is also arranged at the discharge end of the support base, and the end roller is arranged on the support base through a connecting seat; the support shaft, the intermediate roller and the end roller are parallel.
[0005] The unloaded slow-bonding prestressed tendons can be neatly placed on the supporting shaft. If the unloaded slow-bonding prestressed tendons need to be transported, the base can be placed in the carriage, and then the slow-bonding prestressed tendons are placed on the supporting shaft as a whole for transportation. When unloading is required, the reduction motor is started to drive each supporting shaft to rotate, thereby rotating and unloading the multiple slow-bonding prestressed tendons placed on the supporting shaft, which can avoid bumps and wear on the slow-bonding prestressed tendons caused by dragging during ordinary dragging and unloading, and the middle roller and the end roller can both rotate to avoid sliding friction between the bottom of the slow-bonding prestressed tendons and the top surface of the supporting base, thereby effectively protecting the slow-bonding prestressed tendons.
[0006] Preferably, the shaft brackets at both ends of the supporting shaft are respectively integrally formed with baffles, and the plane where the baffles are located is perpendicular to the plane where the supporting shaft is located. The baffles are provided to limit the slow-bonding prestressed tendons on the supporting shaft to prevent the slow-bonding prestressed tendons from sliding off the two ends of the supporting shaft.
[0007] Preferably, the support base comprises a rectangular bottom plate and support legs fixedly connected to four corners of the rectangular bottom plate. Such a configuration is structurally reasonable.
[0008] Preferably, there are two intermediate rollers between adjacent supporting shafts. This arrangement is structurally reasonable and can better protect the slow-bonding prestressed tendons.
[0009] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: simple structure, low production cost, easy use, and can avoid sliding friction between the bottom of the slow-bonding prestressed tendons and the top surface of the supporting base, thereby effectively protecting the slow-bonding prestressed tendons.
