A chain strength detection device for a chain bucket sand dredger

Abstract

The invention discloses a chain strength detection device for a chain bucket type sand-excavating ship. The chain strength detection device comprises a bottom plate, two connecting seats and two chainclamping heads; a detection box provided with an interlayer is fixed on the outer wall of the top of the bottom plate through bolts; limiting plates of the same specification are fixed on the inner wall and the outer walls of two sides of the detection box through bolts; strip-type slots of the same specification are formed in the outer wall of one side of each of the limiting plates and in the detection box; horizontally disposed connecting rods are clamped in the strip-type slots; one side of each of the connecting rods is welded with a vertically disposed toothed plate; and fixed blocks are welded on the outer walls of the bottoms of the connecting rods and the inner wall of the top of the detection box. The chain strength detection device simulates a working environment of the sand-excavating ship and restores an actual working environment of a chain of the sand-excavating ship, so that actual influence of the environment on tensile strength is considered, and the creativeness ofthe device is improved; and L-shaped locking plates and threaded slots can play a limiting role for the chain, so that a steady structural state is created, and the shortcomings in an existing deviceare overcome.

Description

technical field [0001] The invention relates to the technical field of strength detection, in particular to a chain strength detection device for a chain bucket type sand dredging ship. Background technique [0002] With the continuous change of the river course and the continuous loss of water and soil, the accumulation of sand and gravel in the river has become too much, resulting in the current river course becoming a suspended river, and the storage capacity of the reservoir has become extremely small. Some of them have no function of peak regulation and water storage. Discharge the mud and sand washed by the river reservoir to the outside of the river embankment and reservoir embankment to restore the river's water passing capacity and the reservoir's water storage capacity. Therefore, it is often seen that dredgers go to the river to dredge sand. During the work of the dredger, the tensile strength of the chain of the dredger is a key point of its work, so the chain st...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have the following deficiencies: there is no simulation of the working environment of the test piece, and the influence of the working environment on the tensile strength is not considered, which eventually leads to inaccurate test results and malfunctions during use

And above-mentioned patent can't solve this kind of problem, therefore, need badly a kind of chain strength detection device of chain bucket type dredging ship
