Abstract
The utility model discloses a core barrel balancing braking protector used in the air operation equipment, mainly comprising a bracket of the protector, a shell of the protector and braking arms. The shell of the protector is fixed on the bracket of the protector; the middle parts of the trisquare-shaped braking arms are hinged on the shell; the rear end of a transverse arm of the braking arms is connected to the shell by means of a tension spring; the upper end of a longitudinal arm of the braking arms is provided with a rolling wheel which butts against a working wire rope; the independent safety protection wire rope passes through the shell of the protector from top to bottom; the transverse arm of the braking arms is provided with two hinged wedges; the upper parts of the two wedges are narrow, and the lower parts of the two wedges are wide; the two wedges are respectively arranged on two sides of the safety protection wire rope; and the outer sides of the two wedges are provided with four positioning bearings. With simple structure and reliable braking, the utility model has the advantages that the braking range can be adjusted, and the utility model can assure the braking precision, thereby greatly improving the safety performance of the air operation equipment.
Description
(1) technical field
The utility model belongs to aerial work equipment, is specifically related to a kind of safety guard of Lifting basket.
(2) background technology
The safety guard of aerial work Lifting basket requires must be active and intelligent, reaction is fast, braking is reliable, moment stopping distance short.Existing hanging basket protector volume and weight is bigger, and structure is relatively complicated, keeps in repair more frequent.Top movable lug mouth is wide, easily advances foreign matter and causes the brake control lever stuck phenomenon.Though can tilt at hanging basket≤produce braking 8 ° the time, but have some defectives.
(3) summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of safe and reliable hanging basket balancing brake protector is provided.The technical solution adopted in the utility model is: hanging basket balancing brake protector mainly comprises protector carriage, protector housing and brake control lever, protector housing is fixed on the protector carriage, be hinged on the housing in the middle of the brake control lever of trisquare shape, the transverse arm tail end of brake control lever is connected on the housing by extension spring, the trailing arm upper end of brake control lever has roller, roller to be against on the load cable; Independently the safety guard-safeguard steel rope passes up and down in the middle of protector housing, and two pivotally attached voussoirs are arranged on the transverse arm of brake control lever, and two voussoirs are up-narrow and down-wide, divides to be in safety guard-safeguard steel rope both sides; In the two voussoirs outside, four Limit Bearings are arranged.
The utility model is simple in structure, braking is reliable, and the braking scope can be adjusted, and can guarantee brake accuracy, has improved the aerial work device ' greatly.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
(5) specific embodiment
Hanging basket balancing brake protector mainly comprises protector carriage 8, protector housing 16 and brake control lever 12, and protector housing 16 is fixed on the protector carriage 8 by bolt 9, and carriage 8 is welded on the top of hanging basket hoisting.The brake control lever 12 bent intermediate places of trisquare shape are hinged on the housing 16 by axle 6, and the transverse arm tail end of brake control lever 12 is connected on the housing 16 by extension spring 11, and roller 3 is equipped with by axle 4 in the trailing arm of brake control lever 12 upper end, and roller 3 is against on the load cable 2.Independently safety guard-safeguard steel rope 1 passes up and down in the middle of protector housing 16; there are two on the transverse arm of brake control lever 12 by pivot pin pivotally attached voussoir 14,15; two voussoirs 14,15 are up-narrow and down-wide; divide and be in safety guard-safeguard steel rope 1 both sides; in the two voussoirs outside; have 5,7,10,13, four Limit Bearings 5,7,10,13 of four Limit Bearings be in voussoir 14,15 both sides splayed by separately the axle be fixed on the casing 16, be used for limiting the stroke of voussoir 14,15.
When the hanging basket normal operation; stressed stretching the tightening of load cable 2 meetings; support by roller 3; the trailing arm of brake control lever 12 is relatively near safety guard-safeguard steel rope 1; this moment folding wedge piece 14,15 be in by under the position; the gap is bigger between two voussoirs, does not contact with safety guard-safeguard steel rope 1, and hanging basket can freely rise or descend.In case something unexpected happened; load cable 2 get loose or moment disrumpent feelings, roller 3 loses dependence, the trailing arm of brake control lever 12 is outward-dipping; the transverse arm afterbody upwards lifts under the effect of extension spring 11; two voussoirs 14,15 can rise moment, because the position-limiting action of Limit Bearing 5,7,10,13, the gap between two voussoirs 14,15 dwindles; clamp safety guard-safeguard steel rope 1; and more to rising, the gap between two voussoirs 14,15 is more little, and the Clamping force of generation is big more.The downward gravity of hanging basket is big more, and the braking force of generation is just big more, and the braking force of the summation of final generation 〉=dead weight of basket and load-carrying makes hanging basket keep the balance quiescence, reaches the final purpose of safety guard-safeguard.
