Animal recovery support system
A land-based ungulate recovery support and stabilization system includes at least one fall control unit mounted in a recovery space and coupled to a harness via at least one rope. The at least one fall control unit provides means for applying brake force(s) to a land-based hoofed animal, such as a horse, fitted in the harness to manage motion of the animal. By managing motion, an uncontrolled fall, a stagger, and other jerking motions can be avoided to prevent injury.
1 . A land-based ungulate recovery support and stabilization system, the system comprising:
a harness configured to be fitted on an animal, and
a fall control unit mounted in the recovery space and coupled to the harness via a rope, the fall control unit configured to provide means for applying a brake force to the harness through the rope to keep a downward fall velocity or acceleration of the harness within a preset limit during a recovery so that an uncontrolled fall and potential injury to the animal is avoided wherein the fall control unit includes a rope management assembly with a drum mounted for rotation about a drum axis about which the rope is wound, a motor coupled to the drum to drive rotation of the drum to wind the rope around the drum, and a brake system configured to selectively arrest rotation of the drum, and
wherein the rope management assembly includes a rope winder configured to direct the rope during winding into a single layer along the drum in order to minimize give in the rope that might be developed from multiple layers of rope sliding relative to one another during the uncontrolled fall, and
wherein the rope winder includes a threaded rod mounted for rotation about a rod axis parallel to and spaced apart from the drum axis, a line guide through which the rope is directed prior to contact with the drum during winding, and a drive nut fixed to the line guide and engaged with threads of the threaded rod so as to be moved with the line guide along the rod axis during rotation of the threaded rod.
2 . The system of claim 1 , wherein the fall control unit includes a sensor configured to provide a parameter associated with the fall velocity or acceleration of the harness and a controller coupled to the sensor and the brake system, the controller being configured to direct the brake system to arrest rotation of the drum in response to receipt of the parameter associated with the downward fall velocity or acceleration of the harness that exceeds the preset limit.
3 . The system of claim 2 , wherein the sensor includes a position sensor configured to detect a position of the drum that can be extrapolated to determine the parameter associated with the fall velocity or acceleration of the harness.
4 . The system of claim 1 , wherein the motor is coupled to the threaded rod to drive rotation of the threaded rod about the rod axis.
5 . The system of claim 1 , wherein the rope management assembly includes the drum about which the rope wound, an omnidirectional rope guide sleeve through which the rope passes as it exits the fall control unit, the drum about which the rope is wound within the fall control unit, and a pulley over which the rope extends as it moves from the omnidirectional rope guide sleeve to the drum.
6 . The system of claim 5 , wherein the fall control unit includes a sensor configured to inform a parameter associated with the fall velocity or acceleration of the harness.
7 . The system of claim 6 , wherein the sensor includes a position sensor that detects a position of the drum.
8 . The system of claim 1 , wherein rope interconnecting the harness and the fall control unit extends over a pulley.
9 . The system of claim 8 , wherein the pulley is mounted in an overhead location.
10 . The system of claim 8 , further comprising at least one secondary fall control unit mounted in the recovery space and coupled to the harness via a secondary rope.
11 . The system of claim 10 , wherein the at least one secondary fall control unit is configured to provide means for applying a brake force to the harness through the secondary rope to resist motion of the harness away from the secondary fall control unit.
12 . The system of claim 1 , further comprising a lifter sized to selectively lift the animal.
13 . The system of claim 1 , wherein the fall control unit is sized to arrest a fall of the animal without lifting the animal.
14 . A fall control unit for use in a land-based ungulate recovery space, the unit comprising:
a rope management assembly with a drum mounted for rotation about a drum axis about which a rope is wound,
a motor coupled to the drum to drive rotation of the drum to wind the rope around the drum,
a brake system configured to selectively arrest rotation of the drum, and
a controller coupled to the brake system and configured to direct the brake system to arrest rotation of the drum in response to receipt of a parameter associated with a velocity or acceleration of a land-based ungulate coupled to the rope that exceeds a preset limit wherein the rope management assembly includes a rope winder configured to direct the rope during winding into a single layer along the drum in order to minimize give in the rope that might be developed from multiple layers of rope sliding relative to one another during an uncontrolled fall, and
wherein the rope winder includes a threaded rod mounted for rotation about a rod axis parallel to and spaced apart from the drum axis, a line guide through which the rope is directed prior to contact with the drum during winding, and a drive nut fixed to the line guide and engaged with threads of the threaded rod so as to be moved with the line guide along the rod axis during rotation of the threaded rod.
15 . The unit of claim 14 , wherein the fall control unit includes a sensor configured to inform the parameter associated with the velocity or acceleration and to communicate the parameter to the controller.
16 . The unit of claim 15 , wherein the sensor includes a position sensor configured to detect a position of the drum.
17 . The system of claim 11 , wherein each of the at least one secondary fall control units is arranged in a corner of the recovery space, and
wherein the at least one secondary fall control unit is configured to provide means for applying the brake force to the harness through the secondary rope to keep a horizontal velocity or acceleration of the harness within a preset limit when the harness is fitted to the animal during recovery so an uncontrolled stagger and potential injury to the animal is avoided.
