Abstract

The invention discloses a fastening device, and belongs to the technical field of ship construction. The fastening device comprises a fixing seat, two fixing frames, a driving handle, a supporting rod, a supporting plate, a guiding tube, a first driving piece, a second driving piece and a locking bolt. The two fixing frames are vertically arranged on the upper surface of the fixing seat. The driving handle drives the supporting rod to move in the guiding tube horizontally through a first moving shaft and a second moving shaft so that the supporting plate is driven to move in the horizontal direction, and an object to be positioned is positioned conveniently and accordingly. The fixing seat is provided with a vertical bolt hole. The locking bolt is arranged in the vertical bolt hole in a penetrating mode. The lower end of the locking bolt extends to the lower portion of the fixing seat, the lower end of the locking bolt is connected with the bottom of a sliding groove so that the fastening device can be fixed to the sliding groove conveniently, and the fastening device can fix the positioned object firmly. The fastening device is simple in structure and convenient to use, can be repeatedly used, reduces the cost of ship construction and improves the efficiency of ship construction.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to a fastening device. Background technique [0002] During the construction of LNG ships, it is often necessary to place some workpieces on the chute for positioning. The existing method is to set a fixed bracket on the edge of the chute, set a screw and a handle on the bracket, and drive the screw on the chute through the handle. The workpiece is positioned. However, there are many shortcomings in the use of this method, and the working conditions are subject to many restrictions, which are specifically manifested in: (1) setting the screw and handle increases the size of the overall device, which cannot meet the requirements under the working conditions of movement or limited space; (2) This positioning method manually drives the handle, which has low efficiency and poor positioning effect. (3) Too long screw rod length can easily lead to deformation and other conditions, r...
