Abstract
The utility model provides an adjustable hydraulic brake. A traction wheel thereof is mounted on a rotor shaft, a copper gate is mounted between a casing and the traction wheel, the rotor shaft is connected with a drilling machine drum through a coupling, two surfaces of the traction wheel are both cast with vanes forming certain inclined angles with the surfaces of the wheel, and the casing is also cast with vanes with the direction opposite to that of the vanes of the traction wheel. Through adjusting area of the traction wheel covered by the copper gate, hydraulic radius of the hydraulic brake is changed, thereby adjusting magnitude of brake moment of the hydraulic brake.
Description
Technical field
The utility model relates to a kind of auxiliary brake mechanism of rig, particularly adjustable hydromatic brake.
Background technology
In the prior art, the adjusting of the braking moment of hydromatic brake is to adopt the liquid level of regulating hydromatic brake to realize that the high more braking moment that obtains of liquid level is big more, is full of hydromatic brake inner chamber brake force maximum.The available water level of this mode is limited, can not the step-less adjustment water level, and lowest water level will exceed the armature spindle center line, and adjustable range is limited, can not well satisfy the needs of drilling engineering.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of adjustable hydromatic brake is provided, when being used for deep well drilling and transferring drilling tool, alleviates the wearing and tearing of the braking strap of the brake and reel, reduce the calorific value of reel Zhi Dong Grains, realize transferring the auxiliary braking of drilling tool by the hydromatic brake device.
The purpose of this utility model realizes by following measure: a kind of adjustable hydromatic brake, driving wheel 3 is installed on the armature spindle, the front of driving wheel 3 is cast with the blade 8 that becomes certain angle of inclination with wheel face, its back also is cast with the blade 9 that becomes certain angle of inclination with wheel face, also be cast with the blade 10 opposite on the housing 1 with driving wheel 3 direction blades, armature spindle 4 connects with the rig reel by shaft coupling 5, copper gate 2 is installed between housing 1 and the driving wheel 3, rotates the position that feeds axle 6 drive link gears 7 change copper gates 2 and reaches the purpose that changes hydromatic brake brake force.
Above-mentioned driving wheel 3 fronts become the tilt angle alpha of the blade 8 at angle of inclination with wheel face
1Be the 20-50 degree, driving wheel 3 back become the tilt angle alpha of the blade 9 at angle of inclination with wheel face
2Be the 20-50 degree; The tilt angle alpha of the blade 10 on the housing 1
3Be the 20-50 degree.
Above-mentioned copper gate 2 is the governor motion of adjustable hydromatic brake, by regulating the masked area of copper gate to hydromatic brake driving wheel 3, changes its hydraulic radius, thereby regulates the size of hydromatic brake braking moment.
The utility model operating principle is: there is blade on hydromatic brake driving wheel two sides, and the inclination certain angle, also is cast with the blade opposite with the driving wheel direction blade on the housing, and recirculated water injects through lower flange, is full of cavity, flows out from upper flange.When armature spindle is rotated at a high speed by the drive of the bull gear on the rig reel by its axle head pinion, driving wheel produces " pump impeller " effect, centrifugal force gets rid of water to housing at a high speed, water circulates between driving wheel and housing blade, the water slug housing that throws away by driving wheel, return the impact driving wheel again, make it to slow down, the energy of loss is transformed into heat and is taken out of by water.
According to the hydromatic brake characteristic, under the constant situation of rotating speed, change hydraulic radius and also can change the moment of resistance, thereby regulate the size of brake force, the control running speed.The utility model has designed copper gate, by the masked area of adjusting copper gate to the hydromatic brake driving wheel, thereby changes the size that its hydraulic radius is regulated the hydromatic brake braking moment.
