Is generated to lower the transport efficiency and pollute the surrounding environment, the operator first suspends the operation of the belt conveyor 2 so that the damaged part P to be repaired is correctly positioned at the repair position. To stop the circular motion of the belt member 3.

Subsequently, only the roller member 4 corresponding to the damaged portion P is partially dismantled from the stand 5 without disassembling the roller member supporting the circular motion of the belt member 3 as a whole. Secure work space where possible.

Then, the repairing rubber member (not shown) cut and cut according to the size of the damaged portion P is attached to the damaged portion P as an adhesive, and at this time, the iron core constituting the belt member 3 and When the same member remains in the damaged portion P, upper and lower rubber members are attached to each other to temporarily block the damaged portion P.

In this state, the main frame 11 is inserted into the stand 15 corresponding to the damaged portion P by attaching the fastener 15 mounted on the lower frame 11b constituting the U-shaped main frame 11. Mount it.

In addition, the upper and lower subsidiary frames 13a and 13b of the upper and lower subframes 11a and 11b of the main body frame 11 are pulled out or inserted in the horizontal direction, thereby providing the upper and lower subsidiary parts. The upper and lower heat plates 32a are horizontally moved by moving the cylinder members 31a and 31b mounted at each end of the frames 13a and 13b together with the upper and lower heat plates 32a and 32b mounted on the rod ends. The upper and lower heat plates 32a and 32b are disposed above and below the damaged part P, respectively, so that the damaged part P is accurately disposed between the upper and lower frames. The upper and lower sub-frames 13a and 13b are firmly fixed by tightening the fixing bolts 14a and 14b attached to the respective ends of (11a) and (11b).

Subsequently, when the rotation bar 38 disposed between the upper and lower frames 11a and 11b is rotated in the forward direction, the male screw members 38a and 38b of the upper and lower frames 11a and 11b are rotated. The female threads formed at the upper and lower ends of the rotation bar 38 are screwed together, and the male screw members 38a and 38b are formed of right and left screws in different thread directions, so that the upper and lower frames ( 11a) and 11b are spaced between the upper and lower heat plates 32a and 32b of the upper and lower auxiliary frames 13a and 13b at the same time the tip is closed inward with respect to the pivot axis 12.

As the gap between the upper and lower heat plates 32a and 32b is further narrowed, the belt member 3 including the damaged portion P is pressed against the upper and lower sides. At this time, the pressure generated from the pressure driving source (34a) (34b) is measured and checked from time to time by the pressure gauge 35 so that too excessive pressure is not transmitted.

At the same time, when external power is applied through the power cable 32c connected to each heater 32 of the upper and lower heating plates 32a and 32b, the upper and lower portions are caused by the heat source generated from the heater 32. The upper and lower surfaces of the belt member 3 which are in surface contact with the hot plates 32a and 32b, as well as the rubber members inserted into the damaged portion P, are melted together, and the rubber members are fused and bonded to the belt member 3. To be

In addition, when the power supply to the heater 32 is stopped and at the same time the pressurization through the pressure driving sources 34a and 34b is stopped, the rotating bar 38 is rotated in the reverse direction. Since the frames 11a and 11b are pivoted about the pivot 12, the gap between the upper and lower heat plates 32a and 32b is increased to open the upper and lower heat plates 321a and 32b and the belt member. Interrupt the surface contact between (3).

Subsequently, the fastener 15 fitted to the stand 5 is taken out and the main frame 11 is easily separated from the belt conveyor. When the damaged part P, which has been welded and repaired by the rubber member, is sufficiently cooled after a predetermined time, As a polishing machine (not shown), the surface of the belt member 3 is smoothly treated, and the roller member 4, which has been partially disassembled from the stand 5, is remounted and returned to its original state.

On the other hand, when the damaged portion (P) generated in the belt member 3 is inclined in the diagonal direction, since the main body frame 11 is connected through the fastener 15 and the rotating shaft 15a, The main body frame 11 is swiveled with respect to the fastener 15 mounted and fixed to the stand 5 to coincide with the damaged part P in the diagonal direction and the upper and lower heat plates 32a and 32b. It can be done.

Therefore, according to the present invention having the above-described configuration, the main body frame that is easily attached to the stand, and the upper and lower heat plates which are in surface contact with the upper and lower surfaces of the belt member including the damaged portion, compared with the conventional Since the overall structure is simple and the volume is easy to handle, it is possible to improve the transport efficiency and productivity of the transported goods by reducing the work time and equipment down time for repairing the damaged part, and reduce labor for maintenance work. On the other hand, the effect of preventing a safety accident is obtained.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
