Abstract
The utility model belongs to the technical field of mechanical structures, and relates to automatic detection equipment in hoisting of mechanical equipment such as road laying machinery, hoisting machinery, mining machinery and the like, in particular to a detection and alarm mechanism for fracture of steel wire ropes. The detection and alarm mechanism comprises a base, wherein a motor reducing gear is mounted on the base, and is connected with one bearing pedestal through a coupler; a winding drum is mounted on bearing pedestals and are fixed by the two bearing pedestals; steel wire ropes are coiled on the winding drum; a support is further arranged on the base, and first swing rods and second swing rods are arranged inside the support and connected with the steel wire ropes on the winding drum; an approach switch seat is arranged on the support; and an approach switch is fixed on the approach switch seat through bolts. The detection and alarm mechanism is simple in structure, high in safety performance, low in manufacturing cost and wide in application range.
Description
Technical field
The utility model relates to the lifting of the mechanical equipments such as road machinery, elevator machinery, mining machinery, the automatic checkout equipment in the lifting work, is specifically related to a kind of wire cable rupture detection alarm mechanism, belongs to the physical construction technical field.
Background technology
Steel rope is mainly used in lifting, the lifting work of the mechanical equipments such as road machinery, elevator machinery, mining machinery, it has intensity height, Rao Xinghao, from heavy and light, operate steadily, the advantage such as few suddenly fracture.But steel rope in use, unavoidably will produce wearing and tearing, produces Fatigue Deformation.When distortion belonged to elastic deformation, steel rope can also normally use.But when producing permanent plastic deformation when the steel rope overload or owing to external factor, will cause its strength decreased; When plastic deformation reached disrumpent feelings value, steel rope will be disrumpent feelings.In the situation of rope hoisting weight, if its fracture, untimely processing will cause great serious accident.Therefore, in time detect the crack conditions of both sides steel rope, very important to the safety of using.
During automatic checkout equipment uses because the mechanical breakdown such as hawser fracture occurs, can avoid because of wire cable rupture in the equipment use, operational outfit collapses, falls or causes personal casualty, avoids operating personal accidents caused because carelessness continues to use, and guarantees personal security.
Summary of the invention
Of the present utility modelly be to overcome above-mentioned weak point, a kind of wire cable rupture detection alarm mechanism is provided, avoid operating personal accidents caused because carelessness continues to use, guarantee personal security.
The technical scheme that provides according to the utility model, a kind of wire cable rupture detection alarm mechanism, comprise base, motor reducer is installed on the base, motor reducer links to each other with a bearing seat by coupler, reel is installed on the bearing seat, and reel is fixed by two bearing seats, and volume has steel rope on the reel; Also be provided with support on the base, be provided with the first fork and the second fork in the support, the first fork and the second fork link to each other with steel rope on the reel; Also be provided with an approach switch seat on the support, approach switch is done and has been bolted an approach switch.
Described the first fork and the second fork are parallel to reel, and every fork all fixes by a swing link bracket and support, and draws mutually by the steel cable on the reel.
Described motor reducer links to each other with base by a permanent seat.
The utlity model has following advantage: the utility model can cooperating by the fork that is connected with steel rope and approach switch, work by easy mode stop mechanism, can avoid because of wire cable rupture in the equipment use, operational outfit collapses, falls or causes personal casualty, avoid operating personal accidents caused because carelessness continues to use, guarantee personal security, it is simple in structure, safety performance is high, and cost of manufacture is low and applied widely.

The specific embodiment
Shown in Fig. 1 ~ 2, a kind of wire cable rupture detection alarm mechanism comprises base 1, on the base 1 by a permanent seat so that motor reducer 10 be connected with base 1.Be provided with 2 bearing seats 2 that shape is identical and corresponding on the base 1, each bearing seat 2 all is fixed on the base 1 bolt by some.One of them bearing seat 2 links to each other with motor reducer 10 by coupler 11, be provided with a reel 3 between two bearing seats 2, and the axle center of the axle center of reel 3 and motor reducer 10 is on the same level face.
Be provided with the square support 12 of a coating reel 3 of side overlap joint of bearing seat 2 on the base 10, the front end of reel 3 is provided with two rotating shafts of being fixed on the support 12, two rotating shafts are all parallel with reel 3, length is about half of reel 3, also be provided with the square swing link bracket 9 that is positioned at support 12 in each rotating shaft, be provided with first fork 6, second fork 7 parallel with reel 3 in the swing link bracket 9.The first fork 6 and the 27 can rotating shaft be center of circle motion.The first fork 6, the second fork 7 are vertically fixedly tightened respectively by two steel ropes 8 on the reel 3.
Also be provided with a base web on the base 1, the base web is equipped with an approach switch seat 4 perpendicular to base on the base web, by bolt approach switch 5 is installed on the approach switch seat 4.The first fork 6, the second fork 7 can contact with approach switch 5 when rotating.
During use, from reel 3, normally socket out steel rope 8, the first forks 6, the second fork 7 perpendicular to reel 3, and fix the angle of itself and base 1 by the steel cable 8 that sockets out separately on the reel 3.When wherein steel cable 8 ruptures; the first fork 6 or the second fork 7 fall down to reel 3 directions as the center of circle take rotating shaft; another root first fork 6 or the second fork 7 are still held equipment; at this moment; fork in swinging the way be installed in approach switch seat 4 on approach switch 5 contact, pass the signal to Electric Appliance Cabinet after approach switch 5 is triggered, motor internal contracting brake is so that equipment is out of service; can effectively protect personnel and device security, play the effect of fracture detection alarm.
