Abstract

The invention relates to an intelligent hogging moment tensioning device for a bottom die, in particular to an intelligent hogging moment tensioning device for a bottom die, which comprises an expandable mounting frame, and a power supply and a motor are arranged on the mounting frame. The power source and the motor are both electrically connected with the central controller, a tensioning jack capable of ascending and descending is arranged between the mounting frame and the base, a movable foot and a telescopic fixed foot are arranged below the base, a working opening is formed in the base, and an automatic working door is arranged on the working opening. In the first working state, the working door is opened, the tensioning jack penetrates through the working door to move downwards, in the second working state, the working door is closed, the tensioning jack is placed on the working door, and the tensioning jack is arranged in the device, so that the overall tensioning effect can be guaranteed in the operation process of the bridge bottom die, meanwhile, the tensioning stability of the mounting frame is guaranteed, and the service life of the mounting frame is prolonged. And under the action of the fixing feet, the tensioning effect is guaranteed to the maximum extent.

Description

technical field [0001] The invention relates to an intelligent negative bending moment tensioning device for bottom molds, in particular to an intelligent negative bending moment tensioning device for bottom molds. Background technique [0002] In the construction of the bridge bottom form, it is necessary to carry out negative bending moment tensioning. Before the engineering structural components are subjected to external loads, pre-tensile stress is applied to the steel strands in the tension module to improve the bending resistance and stiffness of the components, and delay the delay. The time at which cracks appear, increases the durability of the component. The tensioning equipment in the prior art has a large size and occupies a large area, and during the bridge tensioning process, there are generally many items or tools on the bridge deck, and the movement of the tensioning equipment may be troublesome, and The existing tensioning equipment is all on one side of the...
