Description
Technical field:
The utility model relates to a kind of reel safety catch, is specially adapted to common hoisting crane, the inefficacy of lifting drum transmission device or driving device.
Background technology:
The patent No. that Patent Office of the People's Republic of China is authorized is CN201020667376.5, patent name is " for the disc type safety braking device of Aerial Conveyance for Human in Coal Mine ", this device includes brake disc, plate disc brake, speed sensor, signal controller and hydraulic efficiency gear, be provided with the brake disc and the magnetic steel ring that are fixedly connected with drive wheel in the side of steel wire rope driving wheel, magnetic steel ring is set to be fixedly connected by support and drive wheel, on brake disc, be provided with plate disc brake, the brake shoe of plate disc brake is set to connect with brake disc contact, speed sensor is set to connection corresponding to magnetic steel ring, speed sensor is set to be connected with the input end of signal controller, the mouth of signal controller is set to hydraulic efficiency gear and drives the motor of drive wheel to be connected.In the time that needs are braked, signal controller received signal drives motor, the hydraulic efficiency gear of drive wheel to work simultaneously, drives that plate disc brake is instantaneous carries out safety arrestment.This reel brake device is realized the braking of reel by Driven by Hydraulic Cylinder brake disc, and its shortcoming is: this brake equipment need to arrange special hydraulic power unit, exists the shortcomings such as brake system complexity, brake disc volume are large.
Summary of the invention:
Task of the present utility model is to propose a kind of compact conformation, and braking maneuver is sensitive reliable, simple to operate, a kind of reel safety catch that safety performance is high.
Task of the present utility model completes like this, a kind of reel safety catch, it is characterized in that: supporting seat bolt and support are fixed, on two end faces of described supporting seat, door is housed and is bolted, in the inner circle of supporting seat, have tooth, on the cylindrical of drg inner ring, have and the tooth engaging after supporting seat assembling, the uniform step that has on the inner end surface of described drg inner ring, on described door along in the assembly opening of circumference, electromagnet being installed, the adjacent of each electromagnet is equipped with retarding spring, on the outer wall of reel, be connected with brake hub, on the end face of described brake hub, have groove and coordinate braking with step uniform on drg inner ring inner end surface.Reel can be welding with being connected of brake hub, also can be with bolts, and described groove and the quantity of step are more than at least 3, and the output shaft on motor is connected with reel by reductor.
The utlity model has following effect: the technical program adopts the motion of solenoid actuated brake hub, emergency braking while realizing reel fast-descending, simultaneously spring is realized the reset of brake hub, has compact conformation, simple to operate, braking is reliable, the life-span is long and safety performance advantages of higher.
Brief description of the drawings:
Accompanying drawing 1 is the structural representation of utility model; Fig. 2 is drg inner ring block diagram; Fig. 3 is supporting seat solid.
Drawing explanation: 1, electromagnet; 2, door; 3, supporting seat; 4, bolt; 5, drg inner ring; 6, retarding spring; 7, brake hub; 8, tightening seal washer; 9, reel.
Detailed description of the invention:
The technical program is to be symmetrically installed with paired brake equipment at the two ends of reel 9, also can install in the center of reel, the concrete enforcement of brake equipment as shown in Figure 1, on supporting seat 3, be connected with body with bolt 4, described door 2 is connected with supporting seat 3 by bolt, in the inner circle of supporting seat, have tooth, on the cylindrical of drg inner ring 5, have and the tooth engaging after supporting seat 3 assemblings, the uniform boss that has on the inner end surface of described drg inner ring, on described door, there is assembly opening along circumference, electromagnet 1 is arranged in this assembling, and block and can not lean on supporting seat direction to move by the interior step in hole, the adjacent of each electromagnet is equipped with retarding spring 6, on the outer wall of reel 9, be connected with brake hub 7, reel 9 can be welding with being connected of brake hub, also can be with bolts, furtherly, reel 9 is lined with tightening seal washer 8 among being connected with brake hub 7, be bolted again.On the end face of described brake hub, have groove, coordinate braking with boss uniform on drg inner ring inner end surface, described groove and the quantity of step are more than at least 3, and quantity is identical, and the output shaft on motor is connected with reel by reductor.
When this safety catch is normally off, when reel is not worked, drg inner ring is under the thrust of retracing spring, and the brake hub laminating that the braking step on it and reel link together, brakes; When reel group is normally worked, electromagnet obtains electric, and the suction of electromagnet overcomes the thrust of retracing spring, and drg inner ring leaves brake hub, realizes the normal lifting of reel group.When reel group transmission device lost efficacy or driving device damages while causing the ratio of drum speed and motor speed not meet the transmitting ratio of retarder (driving device between motor and retarder), the speed sensor filling on motor and reel is transferred to master control unit by tach signal by speed sensor, master control unit is by these two signal comparisons, find that the ratio of drum speed and motor speed does not meet the transmitting ratio of retarder, master control unit will send power failure speed-slackening signal, and be transferred to the electromagnet being arranged on supporting seat, electromagnet dead electricity, rely on retracing spring thrust, promoting drg inner ring moves to brake hub direction, the step of drg inner ring projection enters into the breaker slot in brake hub, realize the emergency braking of reel.The utility model adopts the motion of solenoid actuated brake hub, and the emergency braking while realizing reel fast-descending adopts retracing spring to realize the reset of brake hub simultaneously, and compact conformation, simple to operate, braking is reliable, and the life-span is long, safety performance is high.
