Abstract
A support column cylinder assembly is provided for use with a support column assembly having upper and lower support tubes and a slidable clamp component for frictionally clamping the upper support tube relative to the lower support tube. Some embodiments of support column cylinder assembly comprise a first bearing member, a second bearing member, and at least two hydraulic cylinders operatively connected between the first and second bearing members, the at least two hydraulic cylinders being operative to apply a force to the second bearing member relative to the first bearing member. The second bearing member is adapted to be positioned against a clamp component of a support column for applying a force to the support column clamp component relative to the first bearing member.
Claims21
A hydraulic cylinder assembly for installing a roof support of the type in which relative axial movement of clamp member secures first and second telescoping tubular supports, the hydraulic cylinder assembly comprising:
- a first bearing member adapted to engage one of the tubular supports;
- a second bearing member adapted to engage the clamp member;
- and
- at least one hydraulic cylinder operatively connected between the first and second bearing members, the at least one hydraulic cylinder being operative to apply a force to the second bearing member relative to the first bearing member, wherein the second bearing member is adapted to be positioned against a clamp member of a support column for applying a force to the support column clamp component to axially move the clamp member to engage the first and second telescoping tubular supports.
A support column hydraulic cylinder assembly for use with a support column having upper and lower support tubes and a slidable clamp component for frictionally clamping the upper support tube relative to the lower support tube, the support column cylinder assembly comprising:
- an upper bearing assembly for distributing an applied force to a clamp component of a support column assembly;
- a lower bearing assembly for distributing an applied force to a support column base plate;
- a hydraulic pump for supplying hydraulic fluid pressure;
- and
- at least two hydraulic cylinder s operatively connected to the upper and lower bearing assemblies and configured to apply an effective amount of force between the upper and lower bearing assemblies for movably pressing the clamp component in place on a support column assembly when a hydraulic fluid pressure is supplied to the at least two hydraulic cylinders.
A method of using a hydraulic cylinder assembly having first and second bearing members and at least two hydraulic cylinders pivotally connected between the first and second bearing members, for pressing a support column clamp component in place on a support column, the method comprising:
- positioning the first bearing assembly against a support column base plate;
- positioning the second bearing assembly against a clamp component on the support column;
- and
- supplying a sufficient hydraulic pressure to the at least two hydraulic cylinders to apply an effective amount of force to the clamp component to press the clamp component in place on the support column.
A method of setting a telescoping support column comprising first and second telescoping support tubes that are secured by the axial movement of at least one clamp member, the method comprising engaging one end of a hydraulically actuated device to one of the first and second support columns, engaging the other end of the hydraulically actuated device to the clamp member, and operating the hydraulically actuated device to axially move the clamp member to secure the first and second support tubes.
