Abstract
The utility model provides a drop-proof protector for a hoist. The utility model is characterized in that a box body is arranged on a hanging basket of a hoist, and a clamping plate is arranged on the box body; one end of the clamping plate is provided with a pulley and an elastic piece, and the other end is provided with a wedge block which is matched with a wedge groove on the box body. A drop-proof protector is arranged on the hanging basket of the hoist, so that the hanging basket can be effectively prevented from dropping wHen a main steel rope is stretched to break. In addition, the utility model has the advantages of simple structure, reliable drop-proofness, quick braking, etc., being an ideal drop-proof protector for a hoist.
Description
The utility model relates to a kind of fall-preventing protection device, especially a kind of fender guard that can prevent the disconnected rope of gig and fall.
The main effect of gig is that it can be sent to material eminence or be sent to lower from eminence from lower, and is therefore very extensive in Application for Field such as mining industry, building industries.But in construction, operation, regular meeting is because of the disconnected grave accident that causes of the traction steel rope of cable of gig, therefore in actual applications, for guaranteeing the safety of gig, people have studied multiple fall-preventing protection device, but these devices or structure is numerous and diverse, preponderance, the consumptive material power consumption; The course of action of fender guard is long, and distance of fall surpasses the scope (20 centimeters) of national regulation, can not really play the anti-falling protection effect, therefore, is necessary existing anti-fall device is improved.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of gig fall-preventing protection device of reliable, snap catch simple in structure, anti-fall is provided.
The technical solution of the utility model is: hang at gig casing is housed on the basket, casing is provided with clamping plate, and an end of clamping plate is provided with pulley and shell fragment, and the other end is provided with the contract piece that matches with contract groove on the casing.Its middle clamp plate is fixed on the casing by bearing pin, and makes clamping plate around the upper and lower swing of bearing pin.Pulley, blue rise or descends with moving of main steel rope so that the gig main steel rope on this pulley, makes to hang at clamping plate one end by dowel fixes; Shell fragment one end is installed in bottom at pulley, and adjusts by set screw, and the other end of shell fragment places clamping plate other end bottom, so that in the shell fragment effect these end clamping plate are raised up.Two of the fixing anti-fall steel cable of the clamping plate other end, and this end is equipped with up-small and down-big oblique contract piece by pin, and this contract piece matches with the corresponding up-small and down-big oblique contract groove that is arranged on the casing, is provided with anti-fall steel cable between contract groove and contract piece.
The utility model compared with prior art has following advantage and good effect: be provided with above-mentioned fall-preventing protection device on the basket owing to hanging at gig; therefore; can prevent effectively that hanging indigo plant when main steel rope from breaking does not fall; other the utlity model has simple in structure, anti-fall reliable, characteristics such as braking is fast, is a kind of comparatively desirable gig fall-preventing protection device.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan structure figure of the utility model.
Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.
Among the figure; 1 hangs indigo plant for gig; 2 is the casing of fall-preventing protection device; it is fixed on gig by welding or riveted joint and hangs blue 1 top; 3 is clamping plate; be installed on the casing 2 by hinge 9; clamping plate 3 can be around hinge 9 swings; 4 is pulley; be installed in clamping plate 3 one ends by bearing pin 8; this pulley can rotate on bearing pin 8; 5 is the gig main steel rope; its upper end is fixed on the wheel 7; after the other end is walked around pulley 4 and transition wheel 6; link to each other with winch 10, so that realize hanging blue rising or decline under winch drives, 12 is the contract piece; be fixed on clamping plate 3 other ends by pin 13; this contract piece is up-small and down-big oblique, and 11 is the contract groove, constitutes up-small and down-big skewed slot by two blocks 14 that are arranged on the casing 2; correspondence is provided with circular groove 15 on contract groove and the contract piece; be used to put anti-fall steel cable 17, the two ends 18 of anti-fall steel cable 17; 19 all are fixed on clamping plate 3 ends, and by top sheave 16 and lower sheave 20 support fixation; 21 is shell fragment; the one end is fixed on clamping plate 3 bottom lefts, and regulates by screw 22, and the other end places the right bottom of clamping plate 3.
Its working process is: under the normal circumstances, anti-fall steel cable 17 is upper and lower slip in the circular groove 15 between contract piece and contract groove with moving of gig main steel rope 5.When main steel rope 5 is broken suddenly, when the clamping plate of pulley 4 and this end thereof moved down, the other end of clamping plate 3 raised up under fulcrum 9 effects, the contract piece 12 on it in contract groove 11 also with on move, the anti-fall steel cable 17 that is stuck in wherein is stuck, do not fall thereby prevent to hang indigo plant.
