Description
Technical field
The utility model relates to a kind of brake apparatus, especially relates to a kind of Multifunctional brake device for grinding machine.
Background technology
Conventional mill only has drives braking and cylindrical shell braking pattern slowly.Slowly drive braking pattern and have again drum brake brake sticking brake and braking motor braking two profiles formula, the braking moment that these two kinds braking patterns can reach is less, just can not be applied to grinding machine and brake after grinding machine application frequency conversion drive saves traditional slow driving device; Cylindrical shell braking is only applicable to the grinding machine braking that annular generator drives, and required braking moment is very large, is unsuitable for the motor-driven grinding machine braking of other than ring type.
Summary of the invention
Based on the Frequency Drive grinding machine in background technology, the utility model discloses a kind of Multifunctional brake device for grinding machine.This brake gear solves grinding machine safety arrestment, accurately locates, for grinding machine maintenance and lining plate replacing provide necessary facility environment condition; Occur in grinding mill barrel material harden situation time make grinding machine swing in certain angle and brake, through repeatedly several times after the material hardened can be made to get loose, solve and manually enter cylindrical shell and remove the workload of material of hardening; After grinding machine orderly closedown beat to certain angle, grinding machine is braked, can stop grinding machine fast.
In order to realize described utility model object, the utility model adopts following technical scheme:
For a Multifunctional brake device for grinding machine, comprise brake, brake support frame, brake disc, brake hydraulic station and control station; Described brake is pulled out by bolt and is combined on brake support frame, and brake support frame is fixed on ground; Inner ring flange on described brake disc pulls out by bolt the transmission system axle being combined in grinding machine and fastens, and interacting with brake forms frictional force and form damper brake; The oil cylinder of described brake hydraulic station and control station connecting brake.Described brake hydraulic station and control system provide pressure oil to brake oil cylinder, make brake block throw off brake disc to declutch, passing ratio reversal valve regulating brake oil cylinder recirculating oil quantity, control brake shoe is applied to the brake force on brake disc, thus controls the retro-speed of grinding machine.Brake is that passing ratio magnetic valve makes brake oil cylinder by certain speed pressure release, thus controls grinding machine retro-speed.
Each brake support frame described in the utility model is installed simultaneously a pair or two to above brake.
Brake described in the utility model is disk brake: described disk brake is the rear-mounted structure of oil cylinder.Disk brake forms by braking body, disk spring, brake shoe, cylindrical shell, hydraulic package etc.Hydraulic package by oil cylinder, piston, adjusting nut, etc. form.When passing into pressure oil in oil cylinder, disk spring is compressed, and drive brake shoe to leave brake disc, disc-brake is in the state of declutching.When pressure in oil cylinder reduces, spring force discharges, and promotion cylindrical shell and brake shoe move to brake disc direction, produces normal pressure, produces frictional force thus grinding machine is braked under positive pressure between brake shoe and brake disc.
Brake described in the utility model is calliper: described caliper brake is arm of force radial type structure.Caliper brake is become by oil cylinder, tripping spring, the motion arm of force, main force's armed lever, brake shoe, brake shoe angle self adaptation head group.When passing into pressure oil in oil cylinder, tripping spring is compressed, the brought into motion arm of force is toward pulling back, and motion arm of force angle reduces, and promotes main force's armed lever and rotates around hinge, main force's armed lever angle increases, and the brake shoe body of Liang Ge main force armed lever head is corresponding to be left certain distance and declutches.Otherwise when oil cylinder oil return, tripping spring is stretched, the brake shoe body of Liang Ge main force armed lever head closes certain distance and is adjacent to brake disc, thus makes grinding machine brake sticking brake.
The control system of brake control station described in the utility model is PLC control system; Described brake hydraulic station, provides hydraulic oil to disk brake, and disk brake is declutched, and makes the corresponding oil return of disc-brake by the reversing flow of electrical control proportion magnetic valve, thus grinding machine is braked by certain deceleration.After shutdown, whole oil pressure values of disc-brake get back to zero rapidly, make grinding machine be in full braking state.
Hydraulic Station feature is as follows:
Adopt constant pressure variable displacement pump to brake system fuel feeding, the using and the reserved automatic on-line switches.When pressure fuel pump reaches setting value, oil pump variable makes output flow minimum, only for maintaining the leakage rate of oil pump inside.Greatly reduce system heating, can start rapidly when system needs ftercompction, keeping system pressure is at the operate in pressure ranges of setting.
Accumulator apparatus is set, store hydraulic system energy, for providing stable oil pressure when oil pump variable output flow is very little to disk brake, keep disk brake and brake disc gap maximum.Before brake hydraulic station normally works, the pressure oil that oil pump is got enters accumulator by check valve, and when pressure reaches pressure sensor setting value, send " the oil-filled foot of accumulator " signal, system proceeds to " normal operating conditions ".In work, when pressure sensor detects pressure drop to low spot setting value, oil pump is to accumulator repairing.Keep energy storage pressure in setting range.
Set scale reversal valve, provides by PLC control system the commutation that certain scaling signal makes this valve proportional, controls the oil return of dish-type brake oil cylinder, thus controls the retro-speed of grinding machine.
The utility model brake disc is arranged on the shaft coupling between grinding machine mair motor and reductor.
The utility model brake disc is arranged in the shaft extension of grinding machine mair motor non-drive side.
The utility model brake disc is arranged on grinding machine pinion shaft planetary reduction gear side.
