Description
Technical field
A kind of mine hoist complemental brake system of the utility model, is related to what is used under a kind of mine, elevator is entered
The device of row auxiliary braking, belongs to field of mining equipment.It is more particularly to a kind of auxiliary to elevator progress by electromagnetic induction principle
Help the device of braking.
Background technology
At present, in process of coal mining, elevator is the key equipment of whole production process, it is ensured that the safety of elevator
Operation and mining production main task, it is therefore desirable to periodically check the brake shoe brake shoe of elevator, and ensure to be lifted
The stability of brake system, existing brakes is all simple by brake(-holder) block progress friction catch, with brake(-holder) block
Abrasion, easily occur situation about postponing in braking procedure, individually by brakes in itself, can not ensure braking it is steady
It is fixed, cause the range of lift of elevator inaccurate, influence coal production, serious meeting causes elevator failure, it is therefore necessary to
Auxiliary braking is carried out to brakes, although some is improved in each side such as the material of brake(-holder) block, radiator structures, finally
Still the situation of brake failure or delay occurs, influences the job security of elevator.
The content of the invention
In order to improve the above situation, a kind of mine hoist complemental brake system of the utility model provides one kind and passes through electricity
Magnetic induction principle carries out the device of auxiliary braking to elevator.It is simple in construction, it is convenient and practical.
A kind of mine hoist complemental brake system of the utility model is realized in：A kind of mine of the utility model carries
Rise machine complemental brake system by wirerope, fixing axle, pinch wheels, annular groove, mounting screw, connecting plate, magnet coil, permanent magnet,
Bearing, fixes sleeve and fixed ear composition, the fixes sleeve outside are equidistantly equipped with multiple fixed ears, and permanent magnet is put by bearing
In in fixes sleeve, the permanent magnet is loop configuration, and magnet coil is placed in permanent magnet, and connecting plate passes through multiple mounting screws
It is connected with bearing inner race, the center line of the connecting plate and the center line of magnet coil are on same horizontal line, two folders
Bearing up pulley is placed in the both ends of connecting plate by fixing axle respectively, and annular groove, the depth of the annular groove are provided with the outside of the pinch wheels
It is gradually reduced from entrance to most inboard.
In use, fixes sleeve is fixed on into appropriate location by multiple fixed ears first, and make two clampings
Wheel is located at the both sides of wirerope respectively, and when elevator needs to stop, by solenoid ON power supply, magnet coil, which is powered, produces rotation
Turn magnetic field, so as to permanent magnet rotating, and drive bearing inner race to rotate, bearing inner race drives connecting plate to rotate, so as to connecting plate
The pinch wheels at both ends are driven to rotate, two pinch wheels are gradually close to wirerope, and positioned at the both sides of wirerope, so as to gradually by steel
Cable clip is fastened, and on the outside of pinch wheels and when wirerope contacts, wirerope can be sticked into gradually in the annular groove in pinch wheels, so as to
Carry out a step to wirerope to fix, prevent wirerope from moving, the depth of the annular groove from entrance to most it is inboard be gradually reduced set
Meter, can be such that wirerope easily sticks into annular groove, but be difficult to skid off out of annular groove, further improve braking effect, reach logical
Cross the purpose that electromagnetic induction principle carries out auxiliary braking to elevator.
Beneficial effect.
First, it is simple in construction, it is convenient and practical.
2nd, cost is cheap, easy to spread.
3rd, the insensitivity of elevator can be effectively improved.
Brief description of the drawings
Fig. 1 is a kind of structural representation of mine hoist complemental brake system of the utility model.
In accompanying drawing
Wherein part is：Wirerope（1）, fixing axle（2）, pinch wheels（3）, annular groove（4）, mounting screw（5）, connecting plate
（6）, magnet coil（7）, permanent magnet（8）, bearing（9）, fixes sleeve（10）, fixed ear（11）.
Embodiment：
A kind of mine hoist complemental brake system of the utility model is achieved in that in use, first by multiple
Fixed ear（11）By fixes sleeve（10）Appropriate location is fixed on, and makes two pinch wheels（3）It is located at wirerope respectively（1）
Both sides, when elevator need stop when, by magnet coil（7）Switch on power, magnet coil（7）It is powered and produces rotating excitation field,
So as to permanent magnet（8）Rotate, and with dynamic bearing（9）Inner ring rotates, bearing（9）Inner ring drives connecting plate（6）Rotate, so as to even
Fishplate bar（6）Drive the pinch wheels at both ends（3）（3）Rotate, two pinch wheels（3）Gradually to wirerope（1）It is close, and it is located at wirerope
（1）Both sides, so as to gradually by wirerope（1）It is fixedly clamped, and works as pinch wheels（3）Outside and wirerope（1）During contact, wirerope
（1）Pinch wheels can gradually be sticked into（3）On annular groove（4）It is interior, so as to wirerope（1）Carry out a step to fix, prevent wirerope（1）Move
It is dynamic, the annular groove（4）Depth from entrance to the most inboard design being gradually reduced, wirerope can be made（1）Easily stick into ring
Shape groove（4）It is interior, but be difficult to from annular groove（4）Inside skid off, further improve braking effect, reach by electromagnetic induction principle to carrying
The machine of liter carries out the purpose of auxiliary braking.
