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

Embodiment Construction

[0032] In order to understand the above objects, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the features of the present application and the features of the present application can be bonded to each other in the case of an unable conflict.

[0033] The test section of the wind tunnel 3 is fixed to the test section by the hinge 2, and the test segment 3 is used for the switch channel flange 1, such as figure 1 and figure 2 As shown, the locking device for the wind tunnel test segment door is mounted on the test segment gate 3, including two-way action cylinders 5, wedge slide 6, slide 7, and bolt lock assembly 8;

[0034] like Figure 4A , Figure 4b , Figure 4C and Figure 5 As shown, the slide 7 includes an upper slide 71 and a down slide 72 that is symmetrically fixed to the edge of the test segment gate 3, the wedge-shaped sli...

Abstract

The invention discloses a locking device for a door of a wind tunnel test section. The locking device includes a double-acting cylinder that drives the locking device. The two ends of the double-acting cylinder are connected with wedge-shaped sliders. The door of the test section is fixedly connected with a slideway. In the process, the pressing block is pressed against the inclined surface of the wedge-shaped slider, and then locked by the bolt locking assembly. The locking device solves the problems of heavy 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 operating efficiency of the hypersonic wind tunnel.

Description

Technical field [0001] The present invention belongs to the technical field of wind tunnel equipment, and in particular to a locking device for wind tunnel test segment gate. Background technique [0002] Since the wind tunnel is required to perform frequent opening and closing operations, there is an important engineering significance to improve the opening and closing efficiency of the test segment gate. At present, the high ultrasound speed wind hole hinges the test segment on the test section, and the rubber seal is uniformly extruded between the test segment door and the channel flange by the manifestation of a plurality of bolts that are evenly distributed along the edge of the test segment. seal. However, manual locking requires the operator to have a certain seal fastening skill, in order to achieve a uniform force of the rubber seal, otherwise the device sealing performance cannot be effectively guaranteed. In addition, there are more bolts, and multiple operators need t...
