Abstract
The utility model provides a friction drum formula buffer, it includes that the axle both ends are fixed with lock nut, and the left end is equipped with the spring and compresses tightly the dish, and the static friction piece is installed to the centre, and the both ends head of axle is fixed motionlessly on the axle bed, and cylinder internal surface installs and moves the friction disc, moves, the static friction piece is installed in turn. The steel wire rope wound and fixed at one end of the outer surface of the roller drives the roller and the dynamic friction plate to rotate, so that friction buffering force is generated between the dynamic friction plate and the static friction plate. The device has simple and reasonable structure, stable braking force and large adjustable range.
Description
The utility model relates to a kind of emergency device of lifting container, especially a kind of emergency device of friction roll cartridge type, be applicable to the well head or the shaft bottom of the vertical or the inclined shaft of mine, can make lifting container emergency or cooperate as buffer gear or when surpassing the orderly shutdown position in hypervelocity with the check band catching device.
In prior art, lifting container emergency device mainly contains " drg ", the patent No.: 91230516.9, this drg is mainly by in brake drum and the both ends of the surface taper hole thereof the cone slipper being housed, control its friction force by adjusting hold-down nut, but its slipper area of contact is little, so exist friction brake force little, and problem such as the braking force setting range is little.
The purpose of this utility model is that to design a kind of volume little in order to overcome the deficiencies in the prior art part, utilizes friction lining to adjust the friction roll energy disperser of friction brake force, and its braking force is easy to adjust and scope is big.
Task of the present utility model is implemented as follows, and it comprises that a left end head is fixed with hold-down nut, compression plate, spring, axle bed, the other end and is fixed with axle bed, jam nut; On the cylinder with the fixing termination of steel rope of rope guarding plate; Spring is a butterfly spring, and axle bed is that the centre has axis hole, and keyway is arranged on it, and axle bed one side has annular flange, and the opposite side lower bottom part has the supporting leg of outside protrusion; It comprises that also there is spline at the axle middle part, static friction sheet centre hole matches with axle with the spline form, cylinder is cylindrical, inwall has spline, and the movable friction plate cylindrical matches with cylinder with the spline form, and quiet, movable friction plate is alternately installed, there is annular lip the axle bed inboard, match with the axle bed annular lip in the rounded hole of cylinder two ends, axle is a stepped shaft, is fixed on by key in the centre hole of axle bed.
Polygon prism shape axle can also be made by major diameter place, axle middle part, and the static friction sheet central shaft hole that cooperates with it also can be polygonal hole.
Jam nut can replace with shaft shoulder of axle self.
The utility model has following advantage compared with the prior art: this equipment utilization is organized friction lining more and is produced friction brake force, and braking force is adjusted by hold-down nut, and it is easy to adjust and scope is big, a fixed axle is arranged, so roll up when enclosing rotation more steady; Simple and reasonable, volume is little, is convenient to be directly installed on the buntons.
Description of drawings:
Fig. 1 is a constructional drawing of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: as shown in Figure 1, it is made up of axle 1, hold-down nut 2, compression plate 3, spring 4, axle bed 5, key 6, movable friction plate 7, static friction sheet 8, cylinder 9, rope guarding plate 10, steel rope 11 and jam nut 12 etc.; Axle 1 is a stepped shaft, and there are keyway and screw thread in its two, and large-diameter portion branch has the spline groove in the middle of it, or is made for the rib bodily form, and its right-hand member connects jam nut 12 places can be with self shaft shoulder replacement; The disk that compression plate 3 is made of steel, there is circular hole at its center, spring 4 is belleville springs, axle bed 5 usefulness steel are made, there is axis hole the centre, keyway is arranged on it, axle bed one side has annular flange, the opposite side lower bottom part has the supporting leg of projection, circular hole is arranged on it, cylinder 9 be with steel make cylindrical, two ends has outside ring flange, steel rope twines thereon, a plurality of axial splines grooves are arranged on its inside face, big slightly short circular hole at the bottom of the inside face two ends has diameter than groove, so that match with the ring flange place of axle bed 5, movable friction plate 7 is with steel or the superimposed annulus of making of non-metallic material, and a plurality of projections are arranged on its cylindrical, and it matches with spline on cylinder 9 inside faces, static friction sheet 8 is with steel or the superimposed annulus of making of non-metallic material, its endoporus has a plurality of projectioies, or the polygon endoporus, and it matches with the spline or the multiple edge body of axle on 1, rope guarding plate 10 is rectangular slabs, there is circular hole at two, and there is grooving the centre, one termination of steel rope is fixed on an end of cylinder by screw.Right-hand member at axle 1 pins with jam nut 12, connects the axle bed 5 of packing into key, and alternately pack into successively movable friction plate 7, static friction sheet 8 are inserted in cylinder 9 again, connect the axle bed 5 of packing at axle 1 left end key, reinstall spring 4 and compression plate 3, and spindle nose compresses with hold-down nut 2.Steel rope 11 usefulness rope guarding plates 10 are fixed on the right side of cylinder 9, are wound in then on the cylinder surface, draw with suspension bracket from left end and are fixed in the pit shaft.Axle 1 and the static friction sheet of fixing on it 8 are fixed on the axle bed 5 motionless.When steel rope was stressed, pulling cylinder 9 and the movable friction plate 7 that is mated rotated, and made between dynamic and static friction lining and produced friction brake force, so that lifting container has buffer action and emergency when overrunning or surpass the orderly shutdown position.
