Problems solved by technology

However, manual locking requires the operator to have certain sealing and fastening skills in order to achieve uniform force on the rubber sealing ring, otherwise the sealing performance of the equipment cannot be effectively guaranteed
In addition, the large number of bolts requires the cooperation of multiple operators, which occupies a certain amount of human resources, increases the preparation time for wind tunnel tests, and reduces the operating efficiency of hypersonic wind tunnels

Abstract

The invention discloses a locking device for a test section door of a wind tunnel. The locking device comprises a bidirectional acting cylinder for driving the locking device, the two ends of the bidirectional acting cylinder are connected to wedge-shaped sliding blocks, the test section door is fixedly connected to a slide way, the wedge-shaped sliding blocks and the slide way are matched in a sliding mode, and in the sliding process of the wedge-shaped sliding blocks, pressing blocks are pressed on inclined planes of the wedge-shaped sliding blocks and then locked through bolt locking assemblies. The locking device solves the problems of large workload, low efficiency and unreliable sealing performance in the process of opening and closing the test section door of the wind tunnel, and improves the operation efficiency of the hypersonic wind tunnel.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel equipment, and in particular relates to a locking device for a door of a wind tunnel test section. Background technique [0002] Since the doors of the test section of the wind tunnel need to be opened and closed frequently, it is of great engineering significance to improve the opening and closing efficiency of the doors of the test section. At present, the hypersonic wind tunnel hinges the door of the test section on the test section, and manually tightens a number of bolts evenly distributed along the edge of the door of the test section, and then evenly squeezes the rubber sealing ring between the door of the test section and the channel flange. seal. However, manual locking requires the operator to have certain sealing and fastening skills in order to achieve uniform force on the rubber sealing ring, otherwise the sealing performance of the equipment cannot be effectively guaranteed. In...
