A horizontal hook claw wear resistance testing machine

Abstract

The invention relates to a horizontal hook claw wear resistance testing machine, comprising a drive assembly, a simulation assembly and a loading assembly connected in sequence, wherein the simulation assembly includes a second rod and a first rod whose one end is connected with the drive assembly, The other end of the first rod is horizontally connected to one end of the hook, one end of the second rod is connected to the other end of the hook to form an included angle, and the other end is connected to the slider placed on the horizontal track to control the A rod is connected horizontally with the loading assembly. Compared with the prior art, the horizontal horizontal mechanism is used to simulate the up and down linear motion of the hook driving control rod, which can complete the wear resistance test of the hook in two directions, and the setting of the slider can simulate the hook grasping control. In the process of rod testing, the overall height and size of the horizontal mechanism can be controlled, and the cost is lower than that of the real working condition simulation, and the control rod is placed horizontally, which avoids the influence of the counterweight of the vertical testing machine, and the measurement is fast and accurate, which is convenient for installation and debugging. Operational observation.

Description

technical field [0001] The invention relates to the technical field of instrument analysis and measurement control, in particular to a horizontal hook claw wear resistance testing machine. Background technique [0002] The hook claw is an important core part of the nuclear reaction control drive mechanism. When working, the hook claw clamps the control rod and performs up and down adjustment movements. Its working environment is in the environmental medium of the reactor loop, and it is repeatedly in the working and neutral state. The design life should reach several hundred 10,000 times. In order to test the performance of the new hook, there are mainly two types of test technologies currently used. One is to simulate the real working conditions of the whole set of mechanisms. The total length of the motion mechanism is 7-8 meters. The test operation cost is very high; the other type is to use the test machine to simulate the performance of the hook claw. The simulation te...

In order to test the performance of the new claw, there are mainly two types of testing technologies currently used. One is to simulate the real working conditions of the whole set of mechanisms. The test operation cost is very high; the other is to use the test machine to simulate the performance of the hook claw. The simulated test machine occupies a small area and has low operating costs, which can basically simulate the real working conditions.

[0003] Using a whole set of mechanism for real working condition test simulation, its manufacturing cost, site construction cost and operation and maintenance cost are relatively high; the existing simulation test machine, its mechanism is manufactured vertically, which is not convenient for test and observation, and the machine is controlled by crankshaft drive The up and down movement of the rod, due to the counterweight at its lower end, will generate vibration and noise during no-load and running, which will affect the test results and reduce the life of the test mechanism
