Technical Field

The invention belongs to the technical field of atmospheric data subsystem debugging, and particularly relates to a pitot tube clamp.

Background

The atmospheric data subsystem is a main atmospheric parameter and limit parameter information source of the airplane. The system continuously measures signals such as full pressure, static pressure, attack angle, sideslip angle, vertical overload, total temperature and the like through the sensors, carries out data processing and calculation through a computer, and then provides atmospheric data parameters and limit signals for pilots and airborne equipment in the forms of digital quantity, analog quantity and switching value.

Therefore, many systems need to collect relevant data of the atmospheric data subsystem in the debugging process, and in order to meet the requirements for the atmospheric data in the ground debugging process, special equipment and a connecting clamp are usually used for simulating full pressure and static pressure states through an airspeed tube. However, as the airspeed tube is changed, a water leakage hole is additionally arranged, and the original connecting clamp cannot cover the position of the new water leakage hole, so that the air leakage phenomenon can occur at the water leakage hole when the full and static pressure states are simulated, further, the simulated state of the airplane has deviation, and the ground debugging work of related systems is influenced.

If some general clamps are used for plugging water leakage holes, the sealing effect is poor due to the fact that the size is difficult to be completely suitable, the airspeed head is located at the edge position of the airplane, the clamp with the large size is not only inconvenient to mount and fix, but also the redundant parts easily damage the skin of the airplane. The water leakage hole is mainly blocked by a cloth strip or an adhesive tape winding mode before, the air tightness is poor due to the defect of using the cloth strip, the air tightness is often required to be wound and bound again in the debugging process, the adhesive tape can achieve the sealing effect, the viscosity of the adhesive tape is large, the surface of the airspeed tube is easily influenced after the adhesive tape is used for multiple times, the adhesive tape is not easy to find after being wound, the adhesive tape is easy to forget on an airplane, the adhesive tape is easy to damage in the detaching process, the airplane is led to generate redundancy, and the subsequent airplane is influenced to test flight safety.

Therefore, no matter which mode is used, the extra workload of the system debugging operator is increased, the debugging efficiency is reduced, and the production cycle of the airplane is further increased.

Detailed Description

The following further describes a specific embodiment of the present invention with reference to the drawings and technical solutions.

It is to be understood that the appended drawings are not to scale, but are merely drawn with appropriate simplifications to illustrate various features of the basic principles of the invention. Specific design features of the invention disclosed herein, including, for example, specific dimensions, orientations, locations, and configurations, will be determined in part by the particular intended application and use environment.

Fig. 1 and 2 are a schematic structural view and a bottom view, respectively, of a pitot tube clamp provided in an embodiment of the present invention. Referring to fig. 1 and 2, the pitot tube clamp provided in this embodiment includes a knob 1, a lifting bolt 2, a lower limb arm 3, a gasket 4, a rubber pad 5 and an upper arm 6, wherein the upper arm 6 and the lower arm 3 are arranged in parallel, the knob 1 is arranged at the end of the lower limb arm 3, the lifting bolt 2 is arranged perpendicular to the lower arm 3, one end of the lifting bolt 2 is in threaded connection with the knob 1, the lifting bolt 2 is lifted or lowered by rotating the knob 1, a through hole is arranged at the end of the lower limb arm 3 in the perpendicular direction, the lower end of the lifting bolt 2 can be screwed below the lower limb arm 3 through the knob 1 and the through hole, and the gasket 4 is arranged at the end surface of the other end of the lifting bolt 2 for sealing a water; the lower surface of going up support arm 6 is provided with rubber pad 5 for prevent fish tail airspeed head upper surface in the anchor clamps use.

Specifically, the sealing gasket 4 and the rubber gasket 5 are made of rubber; knob 1, jack bolt 2, low limbs arm 3 and upper support arm 6 are stainless steel.

Specifically, knob 1 is used for manual rotation, so that lifting bolt 2 can rise or descend, come the distance between adjustment sealed 4 and the rubber pad 5, and then press from both sides tight airspeed tube and play sealed effect, prevent the hole gas leakage that leaks, sealed 4 that fills up is used for the shutoff hole that leaks, can reach airtight effect and prevent fish tail airspeed tube lower surface again, rubber pad 5 is arranged in preventing anchor clamps use fish tail airspeed tube upper surface, lower limb arm 3 and upper boom 6 are used for supporting anchor clamps and press from both sides tight airspeed tube. The whole size of anchor clamps is moderate, and convenient to carry both had been fit for the factory and has used, also is applicable to the outfield and passes through to change the use, has also avoided simultaneously because the volume too little influences airtight effect or the too big potential accident risks such as aircraft skin and windshield that cause of gouging damage.

This anchor clamps need the integrity of inspection anchor clamps before using, confirm after the no problem, at first anticlockwise rotation knob 1, make lifting bolt 2 descend to the bottom, utilize the ladder to go up the position of aircraft one of them side airspeed tube, make sight and airspeed tube at same horizontal plane as far as possible, observe the hole position that leaks, then overlap anchor clamps on the airspeed tube, make the central point of sealed pad 4 put and aim at the hole that leaks as far as possible, and clockwise rotation knob 1, make lifting bolt 2 rise, observe the skew condition of sealed pad 4 and the hole that leaks simultaneously, in time adjust, until sealed pad 4 and airspeed tube laminating, continue to rotate knob 1, make sealed pad 4 produce the compression volume, the inspection anchor clamps have pressed from both sides tightly and can't remove the back, stop rotation knob 1, later utilize the hole that leaks on another anchor clamps sealed aircraft opposite side airspeed tube with the same mode. After debugging is completed, the knob 1 is rotated anticlockwise, the lifting bolt 2 is made to descend to the bottom, the clamp is taken off, the integrity of the clamp is checked, and the clamp is stored in a tool box after no problem is confirmed.
