Portable real-time force measuring device capable of being detached freely

Abstract

The invention relates to a portable real-time force measuring device capable of being detached freely. The portable real-time force measuring device comprises a base, wherein a force measuring sensor is arranged in the middle of the upper end of the base, and is connected with a digital signal acquiring instrument through a wire; a sensor protecting cover covers the middle of the base and is divided into an upper half protecting cover and a lower half protecting cover; after the upper half protecting cover and the lower half protecting cover are mounted oppositely, two sides of the upper half protecting cover are locked with two sides of the lower half protecting cover through a plurality of bolts; a hole is formed in the upper half protecting cover; the wire penetrates in the hole; and butterfly clasps are respectively arranged at two ends of the base. By using the portable real-time force measuring device capable of being detached freely, airplane holding force on a ship and an ultra-large floating structure can be measured, and a basis is provided for designing and improving a holding cable. Moreover, the device can also be used for measuring traction force of an automobile, balloon/airship holding force and tensile force limited by tensile strength and the size and the range of a testing machine in real time, and can also be used for a stretching ultimate strength test.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a freely detachable portable real-time force measuring device. Background technique [0002] With the development of the ocean transportation industry, the number of ships continues to increase. In order to improve the rescue capability at sea and facilitate the transportation of personnel and materials, most of the ships are equipped with parking pads for the use of helicopters for personnel and material transportation. In order to ensure the safety of the aircraft while the ship is navigating at sea, it is necessary to carry out an aircraft mooring force measurement test to evaluate its safety performance. [0003] When the ship is navigating at sea, the mooring cables of the aircraft will be subjected to a large inertial force of the aircraft, especially in the environment of high sea conditions, the movement of the ship in all directions is relatively large (especiall...

AI Technical Summary

Problems solved by technology

Since the design of the mooring cable is based on a series of assumptions, and the corresponding ultimate bearing tests are carried out in the laboratory, no actual testing has been carried out so far, so it is difficult to guarantee the strength of the overall structure of the entire set of mooring cable equipment under the action of dynamic load. Once there is a flaw in the design, it may lead to the failure of the mooring line, the damage of the aircraft, the injury of personnel, and even the destruction of the ship

At present, there is no device for real-time measurement of the mooring force of the relevant aircraft. It cannot directly measure the actual aircraft, and cannot provide valuable information for the design and improvement of the mooring cable, and it cannot better ensure the safety of personnel, aircraft and ships.
