Background technique
Use the drilling well winch in Process of Oil Well Drilling, the cylinder of drilling well winch is provided with main brake.In order to improve the stability and the Security of boring down, guarantee carrying out smoothly of drilling well, electromagnetic brake, hydromatic brake or hydraulic disc brake also are installed as auxiliary brake on the drilling well winch, auxiliary brake also is one of requisite device of drilling well winch.The performance quality of braking device not only influences work limitation and drilling well cost of production, also is related to the safety of drilling implementer, equipment and oil well.
It is secondary that hydraulic disc brake adopts brake disc and brake block to form brake.The secondary effect of brake provides enough brake torques.As Chinese patent notice of authorization number: a kind of drill disk-type braking device in CN2866449Y provides; Chinese patent notice of authorization number: a kind of drill disk-type braking device of hydraulic control in CN200974755Y provides.Existing brake disc is divided into solid brake disc, air-cooled brake disc and three kinds of forms of water-cooled brake disc.In brake process since the brake disc of hydraulic disc brake device and brake block friction generates heat, heat distributes by brake disc.Solid brake disc abutment surface heat radiation is mainly used in well repairing machine and small-sized drill; There is the natural ventilation road inside of air-cooled brake disc, by natural ventilation road and surface radiating.Big for the large type drill brake torque, just should adopt the water-cooled brake disc.There is water-cooling channel water-cooled brake disc inside, and water outlet and water intake are arranged on internal diameter.During work, provide cooling circulating water for brake disc, reduce the secondary fricative heat of brake by water intake and water outlet.
At present, air-cooled brake disc and water-cooled brake disc mainly adopt welded structure, are shaped as ring.On brake disc, be evenly distributed with mounting hole.The material that uses is 30CrMo, and this material welding performance is good, has better comprehensive mechanical property after modified, and higher intensity is also arranged under the high temperature, and through application in practice for many years, performance has obtained certainly.But for the equipment accumulating of low temperature environment under particularly-60 ℃, and the drillng operation under-45 ℃, above brake disc will manifest many drawbacks.At first, the reduction in strength of brake disc ruptures under heavy duty or impulsive load easily at low temperatures, causes the accident; Secondly, the weld seam of welded brake disc ruptures easily under the low temperature, weld seam internal structure complexity, and its defective is more obvious under low temperature environment; If adopt solid brake disc, the heat that produces during work can not get distributing timely, can influence braking effect equally, the accident of serious meeting generation brake failure, and consequence is hardly imaginable.
The model utility content
The purpose of this utility model is: a kind of hydraulic disc brake device brake disc is provided, improve present brake disc structure, make it can adapt to accumulating and the drillng operation of rig under low temperature environment, improve the low-temperature working performance and the safety reliability of hydraulic disc brake system, overcome the problem that brake disc ruptures easily under the cryogenic conditions.
The technical solution adopted in the utility model is: hydraulic disc brake device brake disc be shaped as ring.Comprise plane, lower plane, mounting screw hole and vent hole, the mounting screw hole of plane and lower plane on being evenly distributed with vertically on the brake disc.Brake disc can be fixed on the braking device by the mounting screw hole, the position in mounting screw hole is same as the prior art.It is characterized in that: annular groove is arranged on the circular cylinder outside brake disc.Be evenly distributed with vent hole between last plane and lower plane, vent hole is a radial arrangement, and the outer end of vent hole is communicated with annular groove.
The ring edge is fluted in the plane on brake disc, and groove evenly distributes.The vent hole relative with groove is inner to be communicated with groove.
At the brake disc lower plane curve bath is arranged, curve bath evenly distributes.The vent hole relative with curve bath is inner to be communicated with curve bath.
Described curve bath is corresponding with the mounting screw hole.
Described vent hole center line is parallel to plane and lower plane.
The quantity of described groove is 16, and the length of groove is between 102～142 millimeters, and the width of groove is between 100～120 millimeters, and the degree of depth of groove is 51 millimeters.
The quantity of described curve bath is 16, and the length of curve bath is between 126～164 millimeters, and the width of curve bath is between 25～50 millimeters.
Brake disc adopts the 30CrMnMo material to forge and makes.
The beneficial effects of the utility model: the utility model hydraulic disc brake device brake disc, mill out the curve bath of some at lower plane, circular cylinder is drilled with vent hole as the air channel outside, can increase heat diffusion area,, not have weld seam because brake disc is solid forging, therefore can stop the breakage problem of weld seam, simultaneously, vent hole can make more abundant that heat distributes, and guarantees braking quality effectively.
Hydraulic disc brake device brake disc adopts the 30CrMnMo material to make, the characteristics of this material are that good processability is arranged, special machining deformation is small, anti-fatigue performance is fairly good, have good low-temperature impact toughness and wear resistance, therefore, select for use this kind material can effectively solve the problem that brake disc ruptures at low temperatures easily.
