Abstract
The invention discloses a brake gear for a heavy-load crane pulley. The brake gear consists of a connecting key slot (1), a brake convex tooth (2), a connecting hole (3), a shaft body (4) and a mounting screw hole (5), wherein the brake convex tooth (2) is arranged at the outer edge of the shaft body (4); the connecting hole (3) is formed in the center of the shaft body (4); the connecting key slot (1) is milled on the connecting hole (3); and the mounting screw hole (5) is equally divided on two end surfaces of the shaft body (4). The brake gear is characterized in that the brake convex tooth (2) is arranged at the outer edge of the shaft body (4) for controlling the rotating direction of the shaft body (4). The brake gear is integrally designed to improve the stress strength so as to satisfy the lifting of heavier objects; the connecting hole is left in the center to bring convenience for output action types in lifting of the objects with different types; and the shaft body can rotate in one direction as needed, and can be temporarily braked in emergency, so that the safety of operators is protected.
Description
Technical field
The present invention relates to a kind of spragging gear.The spragging gear used when being particularly suitable for heavily loaded gin wheel.
Background technology
When hoisting heavy, needs object is overturn and promotes outside lifting machine range of operation or other actions time, sometimes just need pulley to operate, but general pulley is adopt the ratchet be arranged on reach to brake when transferring weight, this mechanism appear in stressed exceed carrying after carry out, pulley there will be the phenomenon of reversing and slippage, threatens larger to the personal safety of operative employee.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of heavily loaded gin wheel spragging gear, be adopt to brake double wedge and S. A. integrated design, rotating shaft center leaves a connecting bore when meeting its working strength.
Technical scheme of the present invention is achieved in the following ways: a kind of heavily loaded whip-gin spragging gear, be made up of connection keyway, braking double wedge, connecting bore, axis body, installation screw, described axis body outer rim is provided with braking double wedge, the center of axis body has connecting bore, connect keyway milling on connecting bore, on two end faces of axis body, decile is provided with installation screw; It is characterized in that: described braking double wedge is located at axis body outer rim, for controlling the hand of rotation of axis body.
Described connecting bore is inserted with outer drive shafts, and keyway and outer drive shafts location will be connected with key, realize outer drive shafts and axis body flush fit.
Described installation screw is provided with the drive disk assembly needing rotation or single direction rotation.
The present invention; the design of integration improve spragging gear by force intensity; enable to meet larger hanging of weight object to get; a connecting bore is left at center; conveniently hang output action type when getting dissimilar object; make axis body can when needed can single direction rotation, can also brake instantaneously when emergency situation, the safety of protection operating personal.
Accompanying drawing explanation
Fig. 1 is main schematic diagram of the present invention.
Fig. 2 is side of the present invention schematic diagram.
Detailed description of the invention
Known by Fig. 1, Fig. 2, a kind of heavily loaded whip-gin spragging gear, be made up of connection keyway 1, braking double wedge 2, connecting bore 3, axis body 4, installation screw 5.Described braking double wedge 2 designs outside axis body 4, and connection keyway 1 and connecting bore 3 design at 4 axis body centers, and installation screw 5 designs on two end faces of axis body 4; Described braking double wedge 2 designs at axis body 4 outer for ending the rotation of axis body 4 in use, makes axis body 4 can when needed can single direction rotation, can also brake instantaneously, the safety of protection operating personal when emergency situation.Described connection keyway 1 and connecting bore 3 design at axis body 4 center, outer drive shafts can be inserted connecting bore 3 in use, with key be connected keyway 1 and realize outer drive shafts and connection of the present invention.Described installation screw 5 designs on two end faces of axis body 4, can be installed the drive disk assembly of the rotation of any needs or single direction rotation in use by installation screw 5.
