Control cabinet for numerical-control synchronous tensioning system for jacks

Abstract

The invention discloses a control cabinet for a numerical-control synchronous tensioning system for jacks, which comprises a cabinet body, and is characterized in that a power module, a control module, a display module and a communication module are arranged in the cabinet body, the power module is connected with an incoming line through a transformer arranged in the cabinet body, the control module is respectively connected with the display module and the communication module, communication interfaces arranged on one side of the cabinet body are connected with the communication module, a control key device arranged on the surface of the cabinet body is connected with the control module, an operating state indicating device arranged on the surface of the cabinet body is connected with the control module, and DTU (data transfer unit) equipment arranged in the cabinet body is used for storing operating state data into a database. The control cabinet can guarantee synchronous tensioning of the two jacks, tensioning quality is ensured, the service lives of construction works such as bridges and the like are guaranteed, and maintenance and operating costs of the construction works at the later stage are effectively reduced.

Description

technical field [0001] The invention belongs to the field of prestressed tensioning control equipment, and in particular relates to a control box for a jack numerical control synchronous tensioning system. Background technique [0002] Prestressed stretching is to tighten the prestressed tendons by jacks, and pre-stress the bridge or component to make the bridge or component produce upward camber, so as to improve the bearing capacity of the bridge or component. There are two types of pre-tensioning methods: pre-tensioning and post-tensioning. The pretensioning method refers to tensioning the prestressed tendons on the pedestal first, fixing the prestressed tendons on the pedestal through anchors, and then pouring concrete. When the concrete reaches the specified strength, the anchorage is removed, the prestressed tendons are loosened, and the strength of the prestressed tendons combined with the concrete is transferred to the concrete. The post-tensioning method refers to...
