Abstract
A tower lift includes a main frame extending in a vertical direction, a carriage module configured to be movable in the vertical direction along the main frame, a weight module disposed behind the carriage module and configured to be movable in the vertical direction along the main frame, a driving module disposed on the main frame and configured to move the carriage module and the weight module in the vertical direction using at least one timing belt, an auto tensioner disposed on a lower portion of the main frame and connected with the carriage module and the weight module by a balance belt, and an upper alignment unit for aligning a horizontal position of the at least one timing belt.
Claims8
A tower lift comprising:
- a main frame extending in a vertical direction;
- a carriage including a lift frame having a rear surface and at least one support plate configured to be movable in the vertical direction along the main frame;
- a weight disposed behind the carriage and configured to be movable in the vertical direction along the main frame;
- a driving module disposed on the main frame and configured to move the carriage and the weight in the vertical direction using at least one timing belt;
- an auto tensioner disposed on a lower portion of the main frame and connected with the carriage and the weight by a balance belt;
- an upper alignment tool configured to align a horizontal position of the at least one timing belt;
- at least one brake mounted to the carriage and disposed in close contact with the main frame;
- and
- at least one carriage robot mounted to the carriage and disposed on the lift frame,
- wherein the at least one brake is mounted on the rear surface of the lift frame and configured to activate during a failure mode to prevent the carriage from falling,
- wherein the at least one carriage robot is mounted to the at least one support plate and configured to transport a receiving container,
- wherein the driving module comprises a pair of diming belts having a first end portion connected with the carriage and a second end portion connected with the weight, respectively, a timing pulley configured in one piece and having a pair of gear portions engaged with the timing belts, and a motor and a reduction gear connected to a drive shaft coupled to rotate the timing pulley, and
- wherein the upper alignment tool comprises a first upper alignment roller disposed between the timing belts, second upper alignment rollers disposed on both sides of the pair of timing belts, respectively, an upper fixed block to which the first upper alignment roller is mounted and upper movable blocks to which the second upper alignment rollers are mounted respectively and configured to be movable in a direction parallel with a central axis of the timing pulley.
