Abstract
The utility model discloses a guide sleeve of a jack. The guide sleeve of the jack comprises a sleeve body and a flange plate; an annular step groove is formed on the outer peripheral face of one port of the sleeve body; the inner peripheral face of the flange plate is sleeved on the outer peripheral face of the annular step groove; and the flange plate and the sleeve body are welded into a whole through a V-shaped welding tank at the contact surface of the annular step groove and the flange plate. The utility model has the advantages that the guide sleeve is formed through welding the flange plate and the sleeve body, the flange plate and the sleeve body are separately forged, so that the utilization rate of material is improved, the processing allowance of parts is decreased, the forging cost of the material is saved, and the cutting cost is lowered; and the V-shaped welding tank is formed at the contact surface of the annular step groove and the flange plate, so that the welding strength is greatly improved, and the service life of the jack is prolonged.
Description
Technical field
The utility model relates to the hydraulic jack fairlead, especially relates to the jack guide sleeve that coal mine hydraulic supporting is used.
Background technology
Forging blank is generally adopted with the fairlead of jack cylinder of hydraulic support frame in the colliery, and the fairlead project organization is the step fairlead, and fairlead blank utilization rate is relatively low, and the forging expense is higher, and the part processing amount is bigger.
The utility model content
The utility model purpose is to provide a kind of stock utilization height, and economical with materials is forged expense, and guarantees the jack jack guide sleeve in application life.
For achieving the above object, the utility model can be taked following technical proposals:
Jack guide sleeve described in the utility model, comprise body and flange, port outer peripheral face at described body offers the ring-shaped step groove, and the groove width of described ring-shaped step groove equals the width of described flange, and the flange inner peripheral surface is set on the described ring-shaped step groove outer peripheral face; Flange and body are welded as a whole by the V-arrangement welding groove that is opened in described ring-shaped step groove and flange contact surface place.
The utility model advantage is fairlead is arranged to flange and body two body structures by being welded, therefore flange and body can forge processing respectively, improved the utilization rate of material, reduced the allowance of part, and saved material the forging expense, reduced the cost of machining; Offer the V-arrangement welding groove at described ring-shaped step groove and flange contact surface place, improved weld strength greatly, guaranteed the application life of jack.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
