Abstract
A hydraulic rescue tool (10) is comprised of a hydraulic thrust apparatus (20) consisting of a hydraulic cylinder body (24) having slots (28) within a hollow end and interlocking ears (36) protruding from the slots. A gland (38) is interfaced between the ears, with the gland and ears connected to the cylinder hollow end with threaded fasteners (98). A connecting link (50) is attached to each interlocking ear and a quick disconnect implement unit (22) is attached to each link and to a piston rod (30) within the cylinder body (24). Six dissimilar embodiments of implement units, each having quick disconnect capabilities and different vehicle structure separating utility are attached to the hydraulic thrust apparatus (20).
Claims46
A hydraulic rescue tool comprising:
- a) a hydraulic thrust apparatus comprising:
- (1) an interlocking hydraulic cylinder body having a hollow end having at least two slots therethrough,
- (2) a piston rod disposed within said cylinder body, said rod having a sealing member slideably affixed thereupon with said rod extending from the cylinder body,
- (3) at least two interlocking ears disposed within the hollow end of the cylinder body and penetrating through the at least two slots,
- (4) a gland interfaced between said interlocking ears, with said gland having at least two fasteners penetrating the gland, jointly interlocking said ears to said gland within the hollow end of the cylinder body,
- b) a connecting link attached to each interlocking ear, and
- c) a quick disconnect implement unit attached to said piston rod and said links for vehicle structure separating.
A hydraulic rescue tool comprising:
- a) a hydraulic thrust apparatus comprising:
- (1) an interlocking unitized hydraulic cylinder body having a hollow enlarged end with a mating pair of slots therethrough,
- (2) a piston rod disposed within said hydraulic cylinder body, said rod having a sealing member affixed thereupon, said rod slideably extending and retracing from the cylinder body,
- (3) a pair interlocking ears disposed within the hollow enlarged end of the cylinder body penetrating through the elongated slots,
- (4) a gland interfaced between said interlocking ears, with said gland having a plurality of seals and at least two fasteners penetrating the gland, jointly interlocking the ears and gland within the hollow enlarged end of the cylinder body,
- (5) a connecting link attached to each interlocking ear,
- (6) a plurality of handles attached to the cylinder body for lifting and operating the rescue tool, and
- (7) hydraulic controls attached to the cylinder body for regulating hydraulic pressure within the cylinder body,
- b) a quick disconnect implement unit attached to said hydraulic thrust apparatus having:
- (1) a yoke with a yoke body attached to the piston rod with a tethered yoke quick release pin, and
- (2) a vehicle structure separating apparatus attached to said yoke.
