Abstract
The utility model relates to a braking device applied to a mine hoist, and the device proposes a new angular displacement brake. The utility model has the characteristics of high mechanical strength, uneasy deformation, large ranging angle, large braking torque, simple structure, easy management and big safety factor, and simultaneously, after a brake band is worn, an upper brake arc plate and a lower brake arc plate are provided with regulating bolts to regulate brake gaps.
Description
The utility model relates to a kind of mine hoist damper brake.
Damper brake on the mine hoist has polytype, as: angular displacement, parallel-moving type, dish brake etc., they have the merits and faults of oneself because of the difference of its structure, again angular displacement damper brakes that adopt on the small mine gig more, the characteristics that lock is moved at the angle are simple in structure, manufacturing cost is lower, but also there are strap of the brake wearing and tearing even inadequately simultaneously, and cause area of contact to reduce, and reduce weak points such as lock torque, there are some gig manufacturers to develop several novel angular displacement damper brakes at present, but there is not bigger breakthrough, the common fault that does not overcome angular displacement and had through patent retrieval, not have the discovery structure identical with the utility model.
The purpose of this utility model is exactly to improve the deceleration and stopping performance of angular displacement damper brake, strengthens the braking effect of lock, increases lock torque, guarantees safe in operation.
The device that the utility model is formed is as shown in the figure: damper brake holds around reel by last valve arc plate (1) and following valve arc plate (2), use rivet (8) the rivet clasp strap of the brake (7) on the arc plate, one end of two arc plates all is processed with pan, hinged with bearing pin (3) and lock seat (5), hinge of common composition, lock seat (5) is fastened on the support (6) with the gong bolt, the other end of arc plate also is processed with pan, last valve arc plate (1) is hinged with bearing pin (9) with upper hinge (10), upper hinge has screw thread in (10), tie bolt (12) screws in wherein, locknut (11) is as fastening tie bolt (12), tie bolt (12) other end screws in hinge (13) down, following hinge (13) links to each other with culdy (16) with bearing pin (14), culdy (16) uses bearing pin (15) to link to each other with following valve arc plate (2) simultaneously, and link to each other with push rod (19) with bearing pin (18), push rod (19) other end connects L type ratch (22) with bearing pin (20), L type ratch (22) links to each other with support (6) with bearing pin (21), simultaneously the tooth on the L type ratch (22) again with remove (24) engagement, backplate (25) is fixed on the both sides of tooth, prevent that two teeth from staggering, and remove (24) are rotated around bearing pin (23) hinged place, regulate bolt (4) and regulate bolt (17) acting on respectively on lock seat (5) and the following valve arc plate (2), as the adjusting play.
Principal feature of the present utility model is: going up valve arc plate and following valve arc plate has certain thickness, thereby the mechanical strength height, not yielding; Each arc plate and reel to hold around angle big, generally between 60 ° to 150 °, area of contact is big, to guarantee to have good braking effect.
The utility model sees accompanying drawing for details: its structure is mainly by last valve arc plate (1), following valve arc plate (2), bearing pin (3), regulate bolt (4), lock seat (5), support (6), the strap of the brake (7), rivet (8), bearing pin (9), upper hinge (10), locknut (11), tie bolt (12), following hinge (13), bearing pin (14), bearing pin (15), culdy (16), setting nut (17), bearing pin (18), push rod (19), bearing pin (20), bearing pin (21), L type ratch (22), bearing pin (23) is removed (24) and backplate (25) is formed.
Move handle (24) with hand during this practical operation, remove (24) are rotated around bearing pin (23), owing to remove tooth and L type ratch (22) on (24) are meshing with each other, so L type ratch (22) rotates around bearing pin (21), push rod (20) passes to triangle with thrust and shoulders bar (16) triangle and shoulder bar (16) and relatively rotate around bearing pin (15), bearing pin (14) drives hinge (13) down, tie bolt (12) and upper hinge (10), upper hinge (10) is again by valve arc plate (1) in bearing pin (9) pulling, and triangle is shouldered the absolute motion that bar (16) produces and is made bearing pin (15) drive valve arc plate (2) down, cause valve arc plate (1) and following valve arc plate (2) to rotate around bearing pin (3), and hold reel tightly, finish braking.
Claims (5)
1, a kind of device damper brake on mine hoist: its structure is held around the reel of gig by two arc flashboards up and down, have one again the cover handling device is supporting and make it to become a kind of new-type damper brake, it is characterized in that: the shared hinge of each end of going up arc flashboard (1) and following arc flashboard (2) holds around lifting drum, and last valve arc plate (1) and following valve arc plate (2) have certain thickness on radial direction.
2, according to claim 1 described device, it is characterized in that: that goes up valve arc plate (1) and following valve arc plate (2) holds around the angle between 60 ° to 150 °.
3, according to claim 1 described device, it is characterized in that: following valve arc plate (2) and lock seat (5) are equipped with respectively regulates nut (17) and (4).
4, according to claim 1 described device, it is characterized in that: remove adopting the tooth transmission between (24) and the L type ratch (22).
5, according to claim 4 described devices, it is characterized in that: removing has backplate (25) to (24) and L type ratch (22) mating teeth both sides.
