Full Text	2 FIELD OF THE INVENTION The present invention relates to an improved holding device with brake attachment to restrict anti-direction movement of a high-speed rotating member during sudden failure of power supply. More particularly, the present invention relates to an improved holding device with brake attachment to control anti-direction movement of a loaded inclined elevated conveyor during power failure so as to place the conveyor in a complete static condition. BACKGROUND OF THE INVENTION In typical steel plant, the raw material like lumps or iron ore, flux like large shape of calcium oxide and calcium carbonate, flespher, lime are generally transported by a conveyor, preferably by an elevated conveyor, from the storage bin to the furnace area. During the transportation of such raw materials through such a conveyor, if sudden power failure occurs, some practical problems generally arise for example, spillage of materials from the conveyor due to rolling, back of the raw materials from the tail end of the conveyor owing to anti-direction movement of the belt. Besides that,, snapping of the elevated conveyor belt occurs due to friction of the raw material slipping from the flat surface of the belt. The conveyor belt also gets over-strained for holding a huge load of materials, particularly during the prolonged period of shut-down. The net result is the loss of production and polluted environment. Further, when the power is restored, the rolling back of belt movement takes place and the fluid coupling and the reduction gear box of the conveyor get damaged due to high torque generation and there is every possibility of snapping the belt needed for 3 movement of the loaded conveyor, which is generally configured of longer size, after the pause period. To overcome the practical adversity with regards to productivity, the prior art manufacturing plants and machineries are generally provided with an in built hold back system embodied inside the gear box which comprises a ratchet unit with ratchet pin to control and restrict the anti-direction movement of the inclined elevated belt. However, such systems start malfunctioning in course of usage within a very short period. Additionally, the replacement of the ratchet pin necessitates atleast 15 to 30 days time, resulting in loss of production apart from extra expenditure. A further effort was made to overcome the first prior art by providing electro pneumatic parking brake. The demerits observed constitute that due to high reverse load and inertia, life of the brake shoe decreases and the sleeves of the brake shoe drum fail leading to failure of the locking arrangement. A still further effort was made by arranging a turn buckle arrangement with a leap spring and brake shoe for development of the existing locking arrangement but such improvement fail to yield any significant result. OBJECTS OF THE INVENTION It is therefore, an object of the present invention to propose an improved holding device with brake attachment which eliminates the difficulties of prior art. 4 Another object of the present invention is to propose an improved holding device with brake attachment which restricts the anti-direction movement of an inclined elevated loaded conveyor belt during power failure. An yet another object of the present invention is to propose an improved holding device with brake attachment which is capable of firmly holding the inclined elevated conveyor belt during power failure so as to prevent rolling back of raw materials. A further object of the present invention is to propose an improved holding device with brake attachment which eliminates spillage of raw materials and fluxes at tail end of an inclined elevated conveyor belt during power failure and also eliminates the wastage of spillage lime which degrades the environment. A still further object of the present invention is to propose an improved holding device with brake attachment that substantially ensures continuous production which is turn reduces production cost. An yet further object of the present invention is to propose an improved holding device with brake attachment which contributes in conserving natural resources including creation of an environment friendly atmosphere. SUMMARY OF THE INVENTION Accordingly, there is provided an improved holding device comprising a circular chuck inserted into an off side of an input shaft of the reduction gear box of the 5 conveyor belt unit. The chuck having a plurality of holes to firmly hold a corresponding number of locking pins. The locking pins each are cylindrical in shape having a head hemispherically configured.
