Mooring hole local structure strength testing mechanism

Abstract

The invention belongs to the field of mooring hole structure strength and in particular relates to a mooring hole local structure strength testing mechanism. The mooring hole local structure strength testing mechanism is composed of a support, a lower double-lug rotary wheel, a lower bolt, a lower single lug, a lower flange disc, a sleeve, an adjusting rod, an ejector pin, an upper flange disc, an upper single lug, an upper bolt, an upper double-lug rotary wheel, a clamp and a plate frame with a mooring hole, wherein the support is a fixed support; four round holes with the same size are formed in four corners of the support; the lower double-lug rotary wheel is in a combined structure of a double-lug structure and an I-shaped wheel and rotates in the support; and the lower double-lug rotary wheel is connected with the lower single lug through the lower bolt and rotates around the lower bolt. According to the mooring hole local structure strength testing mechanism, the I-shaped wheel is matched with a single lug and double lugs and the adjusting rod rotates in the sleeve to adjust the direction; and the adjusting rod is fixed at a certain position in the sleeve through the ejector pin and does not move up and down or rotate, so that a clamping component panel is adjusted and is fixed at any angle. A test piece can be loaded at any angle and a condition that a buttress is repeatedly replaced in a test is avoided.

Description

technical field

[0001] The invention belongs to the field of the structural strength of a systemic cave, in particular to a test mechanism for the local structural strength of a systemic cave. Background technique

[0002] With the development of shipping, the advantages of ro-ro ships in maritime transportation are becoming more and more obvious. In order to avoid the movement and collision of containers or vehicles when the ship is swaying, there are mooring holes on the cargo deck of the ro-ro ship to fix the containers or vehicles. Therefore, it is very important to study the local bearing capacity of tethered caves. In order to study the local bearing capacity of the mooring hole, it is necessary to conduct a local structural strength test of the mooring hole to ensure that the transported items will not be damaged due to collisions during transportation, and at the same time avoid ship safety problems caused by cargo movement.
