Abstract

PURPOSE:To regulate the tension pulley position at the time of start of belt driving in a fixed range to certain belt tension work by connecting a damper to the shaft of a tension pulley in a take-up comprising a tension pulley, weight, and slap pulley. CONSTITUTION:Shock absorbers 7 of spring types or other types are connected to the bearings at both ends of the shaft 5 of a tension pulley 4. In the case of a spring type shock absorber 7, a weight (w) and a spring are adjusted so that the length of spring becomes free when the tension pulley 4 is at the specified position. This constitution allows the spring to the absorb the height of the tension pulley 4 even when lowered once or leaped up due to the reaction at the time of start of belt driving, and as a result the tension pulley 4 is always kept at a fixed position. Therefore, the tension work of the belt is certainly functioned by this constitution.

A tensioning device is used to apply tension to the belt on the slack side. Using the two snap pulleys 2 and 3 as guides, the belt is moved downward and hooked onto the tension pulley 4. Although details are not shown, two bearings on both sides of the shaft 5 of the tension pulley are supported for vertical movement, and a weight device 6 is connected to the bearings. The rectangular W in the figure is a weight. The weight device applies gravity to the tension pulley via the bearing to tension the belt on the slack side. This known take-up weight tensioning device has the following drawbacks.

When the belt conveyor is started, the belt on the slack side loosens, so the tension pulley goes down, but then rebounds upwards, sometimes ending up in a position above the position before starting.

Since the belt is loose on both the tension side and the slack side, the head boot and belt may slip and cause the engine to fail to start. The tension device no longer performs its function.

[Means for Solving the Problems] The belt conveyor take-up of the present invention includes a tension pulley, a weight device connected to its shaft, and a weight device attached to the tension pulley for applying tension to the belt on the slack side of the belt conveyor. In a take-up consisting of two snap pulleys that guide the belt, a shock absorber was connected to the shaft of the tension pulley. The shock absorber is composed of a cylinder, a piston, a piston rod, and oil in the cylinder, and the piston has at least two holes, one of which is equipped with a one-way valve, and the other hole is equipped with the one-way valve. This is a one-way valve and a one-way valve installed in the opposite direction.

[Function] Since the shock absorber is connected to the shaft of the tension pulley, it prevents the tension pulley from falling once when the belt conveyor is started and then springing up due to the reaction, and keeps the tension pulley in a constant position at all times. Keep it in place and allow the belt tensioning device to fully function. The belt conveyor can always be started smoothly without causing belt slip.

In addition to this, the present invention connects the shock absorber 7 to bearings on both sides of the shaft 5 of the tension pulley, which is supported so as to be movable up and down. Usually, the bearings 8, 9 on both sides of the snap pulley 2.3 are mounted on a frame. The illustrated frame 10 is installed using a frame, and the shock absorber is fixed thereto.

Shock absorbers can be spring type, hydraulic type, etc. A spring-type shock absorber includes, for example, a cylinder 7a and a rod 7b, as shown by the arrow 7 in the figure. A spring is built inside the cylinder, and the rod is connected to the spring. The weight and spring are adjusted so that the spring has a free length when the tension pulley is in a predetermined position. The spring prevents the tension pulley from dropping once when the belt conveyor is started, and then from jumping up due to the reaction.
