Abstract
Systems and methods for testing and certifying swivels such as are used for line and cable pulling are disclosed. The disclosed systems and methods for testing and certification may be used to ensure the tested swivels are still suitable for use in industrial settings. Devices for performing the described testing procedures are also disclosed herein.
Claims19
A test platform for testing swivels, comprising:
- a testing assembly having a first portion and a second portion connected by at least one support member;
- the first portion having a hydraulic cylinder operationally connected to a first swivel attachment point-;
- and
- the second portion having a drive system operationally connected to a second swivel attachment point;
- a torque transducer configured to measure torque applied to a swivel coupled to the first swivel attachment point and the second swivel attachment point;
- and
- a controller device configured to detect applied torque and compare the applied torque to a predetermined threshold.
4 more elements
An apparatus for testing components, comprising:
- a linear actuator having an attachment point and configured to apply a tension force to a component attached to the linear actuator attachment point;
- a rotational actuator having an attachment point and configured to apply a torque to a component attached to the rotational actuator attachment point;
- a component operationally attached to the linear actuator attachment point and the rotational actuator attachment point;
- and
- a controller operationally connected to the linear actuator and to the rotational actuator, the controller being configured to determine the tension force applied to the component by the linear actuator and to measure the torque applied to the component by the rotational actuator.
2 more elements
An apparatus for testing a line pulling swivel, comprising:
- a testing assembly having a first portion and a second portion connected by a plurality of support members and defining a testing volume between the first portion, the second portion, and the plurality of support members;
- the first portion having a hydraulic cylinder connected to a first connection member;
- a first swivel attachment point disposed within the testing volume and connected to the first connection member;
- the second portion having a drive system rotatably connected to a rotatable drive shaft;
- a second swivel attachment point disposed within the testing volume and connected to the drive shaft.
