Description
Technical field
The application belongs to mine transportation lifting means, relates in particular to lifting winch.
Background technology
In the mine hoisting transportation, mainly use lifting winch (gig) to promote, lifting winch is made up of motor, change speed gear box, cylinder and bearing seat.Need often speed-raising or deceleration because winch is in operation, so be provided with service brake again, safety misadventure takes place because winch has been in operation again, needs emergency brake, so also be provided with safety catch.Brake mode is by dish lock formula and explosion type, and relevant with the application is band brake type.
Traditional band brake type brake mode adopts manpower lever's brake equipment, it comprise between motor and the change speed gear box brake wheel and about the lock arm of two band brake shoes, the lower end of two lock arms is hinged on the base respectively, the upper end is hinged on respectively on two adjacent fulcrums of a culdy, by manual operation lever far-end, reach the purpose that declutches and make lock, thus operation of control lifting winch or parking.This service braking mode, labour intensity is big, the fault rate height.
Traditional band brake type safety arrestment mode adopts the angle to move (or translation) weight hammer type brake equipment, for example the basic structure of angular displacement is, a braking wheel is arranged on winch drum, a braking wheel both sides are provided with two lock arms, on the lock arm friction lining are arranged, and are hinged with horizontal tie-bar on a lock arm, be hinged with culdy on another lock arm, the other end of intermediate rod is hinged on the last fulcrum of triangular draw bar again, and the far-end fulcrum of culdy also has a cover leverage, and has hung weight.During the lifting winch operation, weight holds up with bracing or strutting arrangement (as hydraulic column), and lever system loses hammer power, and two lock arms separate with a braking wheel under the effect of culdy.When needing drag, fall the picking-up thing, lean on the gravity of weight that lever is pressed down, thereby two lock arms are exerted pressure to a braking wheel, realize braking.This brake mode is finished by a weight and a cover lever system, complex structure, and poor stability, braking effect is poor, also takes up room.
Summary of the invention
The application's purpose is the deficiency that overcomes above-mentioned lever band brake type and weight band brake type brake mode, and it is transformed, and a kind of hydraulic contracting brake type double braking winch is provided.
The application's technical scheme is, it comprises motor, change speed gear box, cylinder, drum shaft bearing, service brake and safety catch, service brake is to establish the work system driving wheel on the adapter shaft of motor and change speed gear box, and there is the service braking lock arm of the band brake shoe that is hinged on the base work system driving wheel both sides; Safety catch is to establish safety arrestment to prop up wheel on the cylinder disk, the wheel both sides are propped up in safety arrestment the safety arrestment lock arm that has friction lining, on a lock arm, be hinged with intermediate rod, be hinged with culdy on another lock arm, the other end of intermediate rod links on the proximal fulcrum of culdy again, and its feature also comprises:
1, is hinged with the hydraulic spring push rod between two lock arms of service brake;
2, the culdy distal end articulated of safety catch has the hydraulic spring push rod, and hydraulic spring push rod bottom is hinged on the lower margin pull bar.
3, the hydraulic spring push rod is made up of oil cylinder, sleeve pipe, pull bar, spring and big nut.Its structure is that pressure spring is housed in sleeve pipe, passes a pull bar in the middle of the pressure spring, and pull bar freely stretches out from the sleeve A end, and the rod head that stretches out is threaded and goes up articulated joint; The pull bar afterbody screws on big nut and withstands spring; At sleeve pipe internal fixation one hydraulic ram, the piston rod of oil cylinder withstands on the pull bar afterbody; Cut with scissors ear on the B end captive joint of sleeve pipe, hydraulic ram is controlled with electro-hydraulic proportional valve, and electro-hydraulic proportional valve is connected on the control cock with oil pipe.
During operation, operating cylinder makes the piston masthead move pull bar to stretch out, the lock arm is unclamped; Operating cylinder is withdrawn in the sleeve pipe piston rod withdrawal, pull bar during parking under spring support power, and the lock arm is held tightly.Adjust the braking force of the big nut setting band-type brake on the pull bar.
Since adopt the lock arm action of hydraulic spring push rod Control work brake equipment and safety control, so following good effect is arranged: the one, declutch by electro-hydraulic proportional valve control, make lock by spring force, operation automation; The 2nd, by the spring size of Control work lock torque flexibly, be active in one's movements, safety is good; The 3rd, the pulling force of spring is adjustable, thereby adjusts braking force, good braking effect flexibly; The 4th, hydraulic ram flexible operation, stable performance; The 5th, simple in structure, it is little to take up room.
