Abstract
The utility model relates to a braking device for an arresting gear of hoisting conveyance. The utility model is provided with a winding drum, wherein conical bodies provided with interleavers are arranged in taper holes on both ends of the winding drum, and then, the winding drum is installed on a fixed axle of which both ends are respectively installed on a left base for the fixed axle and a right base for the fixed axle, wherein bulges on the left base for the fixed axle and on the right base for the fixed axle clamp the conical bodies, and springs and a compact disk are orderly installed on a fixed axle on the left side of the left base for the fixed axle and are fixed by compression nuts. The left base for the fixed axle and the right base for the fixed axle are fixed to a base plate to which a protective casing is fixed by screw nails, one end of a wire rope is fixed to the winding drum, and the other end of the wire rope is wound in a plurality of circles, and then, penetrates through a hole on the base plate. The utility model has the advantages of small size and large and stable braking force which is easy to be adjusted.
Description
The utility model relates to a kind of drg of lifting container emergency device, is applicable to the well head or the shaft bottom of the main shaft and the inclined shaft of mine, makes lifting container emergency when surpassing the regulation running velocity or when surpassing the orderly shutdown position.
The prior art in present technique field is: lifting container emergency device, the patent No.: 89208807.9.The drg of this device mainly is made up of brake drum, braking brake shoe, housing and end cap etc.The braking brake shoe is placed in the groove of both sides of brake drum, is placed in together in the housing then, and both sides are sealed with end cap, and this drg volume is big, be difficult for being installed on the buntons, and braking force is difficult for adjusting.
The purpose of this utility model is to have designed the drg that a kind of volume is little, braking force is easy to adjust in order to overcome above-mentioned the deficiencies in the prior art part.
The purpose of this utility model is achieved in that a kind of drg of lifting container emergency device; include a reel; have sipes on the cylinder; have through hole along line of centers; and have the garden taper hole on the both ends of the surface; the cone of band centre hole is placed in the taper hole of reel both ends of the surface; reel and cone are sleeved on the anchor shaft together; and anchor shaft is placed in a left side of being fixed on the base plate; on the right fixed shaft seat; on a left side; there is projection to be stuck in the shrinkage pool of the big end of cone on the axis hole position of right fixed shaft seat; on the anchor shaft in the outside of left fixed shaft seat, spring and compression plate are housed successively; and fix with hold-down nut, being used for regulating the size of braking force, protective case is airtight with whole device; steel rope one end is fixed on the reel, and other end passes base plate and outwards draws.
The utlity model has following advantage: this apparatus structure is little, can be directly installed on the buntons, and an anchor shaft is arranged, and produces the revolution imbalance problem when having avoided the reel rotation, employing garden awl friction face, and braking force is stable greatly again, and the braking force adjustment is easy.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The utility model is described in further detail with reference to the accompanying drawings:
With reference to accompanying drawing: a kind of drg that is used for lifting container emergency device; mainly by anchor shaft 1, right fixed shaft seat 2, cone 3, friction lining 4, steel rope 5, reel 6, left fixed shaft seat 7, spring 8, compression plate 9, hold-down nut 10, protective case 11, base plate 12 are formed.Reel 6 profiles are the garden column, on its cylinder sipes is arranged, steel rope is twined on it, have the axis hole along line of centers, have taper hole on the both ends of the surface, cone 3 usefulness steel are made, have axis hole along line of centers, the side's of having groove also on the large end face is fixed with friction lining 4, two cones 3 and is placed in respectively in two taper holes of reel 6 on the conical surface, reel 6 and cone 3 are set on the anchor shaft 1, the cone 3 on right side nestles up on the shaft shoulder of anchor shaft 1, and left fixed shaft seat 7 and right fixed shaft seat 2 usefulness steel are made, and its top all has the hole, garden, the side's of having projection around the hole, one side garden, left fixed shaft seat 2 and right fixed shaft seat 7 are separately fixed on the base plate 12, and anchor shaft 1 is installed in two holes on it, and the right-hand member of anchor shaft 1 cooperates with right fixed shaft seat 2 usefulness keys; Square projection on left fixed shaft seat 7 and the right fixed shaft seat 2 is stuck in cone 3 large end face side's grooves, and cone 3 can not be rotated.On the anchor shaft 1 in the left side of left fixed shaft seat 7 spring 8 and compression plate 9 are housed successively, the outside is fixing with hold-down nut 0, and said spring 8 is selected butterfly spring for use.Protective case 11 is airtight with whole device, and protective case 11 is screwed on base plate 12.One end of steel rope 5 is fixed in reel 6 grooves, passes base plate 12 holes after twining several circles.
Claims (2)
1; a kind of drg of lifting container emergency device; it is characterized in that: include reel 6; profile is on the cylinder of garden column sipes; have the axis hole along line of centers; the two sides has taper hole; cone 3 has axis hole along line of centers; the side's of having groove also on the large end face; be fixed with friction lining 4 on the conical surface; then two cones 3 are placed in respectively in two taper holes of reel 6; reel 6 and cone 3 are installed on the anchor shaft 1; anchor shaft 1 two ends are placed in respectively in the hole on left fixed shaft seat 7 and the right fixed shaft seat 2; square projection around the hole, one side garden is stuck in the square groove of cone 3 left side; right fixed shaft seat 7; 2 are separately fixed on the base plate 12, on the anchor shaft in the left side of left fixed shaft seat 7 spring 8 and compression plate 9 are installed successively; fixing with hold-down nut 10; protective case 11 is screwed on base plate 12, and steel rope one end is fixed in reel 6 grooves, passes the hole of base plate 12 after the other end is wrapped on the reel.
