Description

Large-tonnage adjustable prestress carbon fiber plate anchoring device Technical Field The utility model relates to the technical field of road and bridge reinforcement, in particular to a large-tonnage adjustable prestress carbon fiber plate anchoring device. Background The large-tonnage prestress carbon fiber plate anchoring device is special equipment for reinforcing structures, and is mainly used for anchoring prestress carbon fiber plates so as to ensure that the carbon fiber plates can effectively transmit prestress, improve the bearing capacity and durability of the structures, and further reinforce and repair the structures such as bridges, buildings and the like. Such devices typically include a fixed end and a tensioning end to effect the pre-stressing and holding of the carbon fiber sheet by clamping the pre-stressed carbon fiber sheet. The fixed end provides strong anchoring force, ensures that the carbon fiber plate does not slide or pull out under a high stress state, and keeps the effective transmission of prestress. The tensioning end ensures that the clamping force on the carbon fiber plate is uniformly distributed, and the damage or the damage of the carbon fiber plate caused by stress concentration is avoided. Through searching, chinese patent with publication number CN219508397U discloses an anchoring device of a prestress carbon fiber board, wherein the carbon fiber board is placed in an installation groove of the anchoring board and is initially fixed by pressing nails. The eccentric is then rotated by operating a handle on the eccentric. The rotation of the eccentric wheel can push the sliding rod to slide in the sliding hole (the sliding hole is a square hole, the cross section of the sliding rod is square, and the rotation is prevented), so that the limiting plate is driven to move. Due to the action of the compression spring, the limiting plate can apply tension to the carbon fiber plate in the moving process, so that prestress application is realized. When the eccentric wheel rotates to a certain angle, the self-locking plane of the eccentric wheel is attached to the limiting plate, the self-locking stretching device is in a self-locking state, and the carbon fiber plate is firmly fixed on the anchoring device. In the self-locking state, even if a large pulling force is applied to the outside, the carbon fiber plate cannot slip or loosen. The problem in the prior art is that when self-locking is realized only by means of the lamination of the eccentric wheel self-locking plane and the limiting plate, the adjustment of the prestress applied to the carbon fiber plate is difficult to ensure, so that the self-adaptive capacity of the device is poor, meanwhile, when the carbon fiber plates with different widths are encountered, the mounting groove can not be perfectly matched, so that the problems of deflection, inclination and the like of the carbon fiber plate occur in the mounting process, the accurate application and the anchoring effect of the prestress are influenced, and the self-adaptive capacity of the device is poor. Disclosure of Invention Aiming at the problems, the utility model aims to provide a large-tonnage adjustable prestress carbon fiber plate anchoring device, the width and the prestress of which are adjustable, and the self-adaption capability of the device is good. The technical scheme adopted by the utility model is characterized in that the anchoring plate is split into the first fixing plate and the L-shaped fixing plate, the width of the anchoring plate is adjustable through sliding connection between the first fixing plate and the L-shaped fixing plate, a telescopic rod is used for providing power, the telescopic rod controls the rotation of the rotating assembly, and the push rod is pushed or pulled to slide, so that the prestress is controlled. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: A large tonnage adjustable prestress carbon fiber plate anchoring device, comprising an anchoring plate for large tonnage carbon fiber plate anchoring, further comprising: The mounting seat is mounted on the anchoring plate through a connecting piece; The adjustable prestress applicator is positioned in the mounting seat, and the force application end penetrates through the connecting piece in a sliding manner, so that the prestress of the carbon fiber plate is adjusted. Further, the anchoring plate comprises a first fixing plate and an L-shaped fixing plate; The first fixing plate is in sliding connection with the L-shaped fixing plate, and the first fixing plate and the L-shaped fixing plate are sleeved outside the end part of the large-tonnage carbon fiber plate. Further, the connector comprises: the mounting plate is detachably connected with the anchor plate; The U-shaped limiting block is arranged on the mounting plate and embedded in the mounting seat. Further, the adjustable prestressing force applicator in
