Abstract
Description
Technical field:
[0001] The utility model belongs to the technical field of container lock testing, and in particular relates to a container lock force testing tool. Background technology:
[0002] Currently, the mainstream mode of transportation in international trade is container transportation. In the container transportation industry, lashing locks are widely used. They can effectively improve the container ship's ability to resist wind and waves and prevent the container from swinging in the wind and waves, greatly improving the stability and safety of the ship.
[0003] The strength of container lashing locks is a crucial parameter in their design and production. Mechanical analysis of the forces acting on container locks breaks them down into pressure, shear, and tension. Existing test fixtures can only test pressure, shear, or tension individually, failing to fully simulate the angles at which the locks are subjected and failing to measure the effects of these forces on the lock. Designing a test fixture capable of simultaneously testing pressure, shear, and tension to maximize the simulation of the forces acting on the locks is a crucial challenge.

The output end of the third oil cylinder is vertically connected to the beam above the test unit at the right end of the beam. The tension applied to the lock is tested by the third oil cylinder.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] By operating the shear force simulation mechanism, the pressure simulation mechanism and the tension simulation mechanism simultaneously, shear force, pressure and tension can be applied to the binding simulation mechanism at the same time.
