Intelligent tensioning equipment of vertical prestressed tendon for bridge construction

Abstract

The invention discloses intelligent tensioning equipment of a vertical prestressed tendon for bridge construction. The equipment structurally comprises a mobile wheel, a device shell, a transmission device, a jack, a controller, a pressure gauge, a pushing handle and an oil tank, wherein the mobile wheel is located on the lower surface of the device shell and is movably connected to the device shell; the transmission device is embedded into the device shell; the jack is movably mounted on the upper surface of the transmission device; the controller is located on the right side of the upper surface of the device shell and is movably connected to the jack; and the pushing handle is fixedly mounted on the upper surface of the device shell. According to the equipment disclosed by the invention, the tensioning jack can be lifted to adjust the position without manually lifting the jack when the tensioning equipment carries out the tensioning work, and the jack can be placed in the device, sothat the device is prevented from being bumps externally. Therefore, purposes of further perfecting the device and guaranteeing the service life can be achieved.

Description

technical field [0001] The invention is an intelligent tensioning device for vertical prestressed tendons used in bridge construction, and belongs to the field of tensioning equipment. Background technique [0002] The prestress tension equipment is the equipment used to apply the prestress value, and the value related to the prestress is generated through the work tension of the equipment. The prestressed tensioning equipment is mainly used in conjunction with the jack used for tensioning and the electric oil pump used for tensioning, and the prestressing value is given by increasing the strength of the steel strand or steel bar in the anchor. [0003] Prestressed reinforcement is the compressive stress applied to the concrete of the structural member in advance by pre-tensioning or post-tensioning before the structural member is used. [0004] For reinforced concrete structures, there will be cracks in the components under tension. Although it does not affect safety, it d...
