The skilled person will understand that the "pulling up the tensioning roller 2" is not limited to being directed straight upward, but may be directed obliquely upward.
The tensioning device mainly comprises a pair of redirection rollers 1, a tensioning roller 2, a tensioning mechanism and a device frame 8, and has few parts and simple structure. When in use, the tensioning device is arranged at the head or the tail of the belt conveyor, the tensioning roller 2 is positioned at the position, closest to the conveyor, of the stroke of the tensioning roller 2, then the head or the tail of the conveying belt 100 is redirected by the redirecting roller 1 and then sleeved on the tensioning roller 2, and then the tensioning mechanism provides tension to tension the conveying belt 100; it can be seen that the above described tensioning device is convenient to use. The take-up roller 2 is moved upward to take up the belt 100, rather than left or right, thereby reducing the footprint of the take-up assembly. Since the tensioning device is not located below the conveyor belt 100, material on the conveyor belt 100 does not fall into the tensioning device.
Further, in the present embodiment, in order to reduce the floor area as much as possible, the longitudinal section of the device frame 8 is a rectangular structure, and in other embodiments, the device frame 8 having a trapezoidal longitudinal section may also be adopted to improve the stability of the device frame 8.
In the present embodiment, the apparatus frame 8 includes a first vertical portion 81, a second vertical portion 82, a first horizontal portion 83, a second horizontal portion 84, a third horizontal portion 85, a first inclined portion 86, and a second inclined portion 87, and the head or tail of the conveyor belt 100 enters the apparatus frame 8 from the second vertical portion 82 toward the first vertical portion 81.
Both ends of the first horizontal portion 83, the second horizontal portion 84, and the third horizontal portion 85 are fixed to the first vertical portion 81 and the second vertical portion 82, respectively, the first horizontal portion 83 is disposed at the top of the device frame 8, the second horizontal portion 84 and the third horizontal portion 85 are disposed at the lower portion of the device frame 8, and the third horizontal portion 85 is located below the second horizontal portion 84.

The first inclined portion 86 and the second inclined portion 87 provide a mounting position for the redirecting roller 1 while also providing a reinforcing effect to the apparatus frame 8.
Further, the mounting frame 8 further includes a first reinforcing portion 88 and a second reinforcing portion 89, both ends of the first reinforcing portion 88 are fixed to the first vertical portion 81 and the first horizontal portion 83, respectively, both ends of the second reinforcing portion 89 are fixed to the second vertical portion 82 and the first horizontal portion 83, respectively, and the first reinforcing portion 88 and the second reinforcing portion 89 reinforce the mounting frame 8, so that the mounting frame 8 is not easily shaken, thereby making the movement of the tightening roller 2 more stable.
Further, the tightening mechanism includes a tightening rope 4, a fixed pulley 3 and a weight 5, the fixed pulley 3 is fixed on the first horizontal portion 83, the tightening roller 2 is located below the fixed pulley 3, one end of the tightening rope 4 is connected to the tightening roller 2, and the other end thereof is connected to the weight 5 across the fixed pulley 3. The tightening mechanism pulls the tightening roller 2 by using gravity without using electric power, is low in cost and simple in structure, and can apply a stable pulling force to the tightening roller 2. In other embodiments, existing power machines (e.g., a lead screw and a motor) may be used as the tightening mechanism to apply the tension to the tightening roller 2.
Further, the above-mentioned tightening means further comprises a partition 9, and the partition 9 is horizontally disposed on the second horizontal portion 84, i.e., below the tightening roller 2 and the weight 5, to prevent the tightening roller 2 and the weight 5 from being suddenly dropped to damage equipment below the partition 9 in an accident state.
Furthermore, the tensioning rope 4 is a steel wire rope, so that the strength is high, and the cost is low. In other embodiments, the tension cord 4 may be made of other materials.
Furthermore, the number of the fixed pulleys 3 is two, the horizontal distance between the two fixed pulleys 3 is greater than a first threshold value, the first threshold value is one half of the sum of the transverse widths of the weight 5 and the tensioning roller 2, one end of the tensioning rope 4 is connected with the tensioning roller 2, and the other end of the tensioning rope strides over the two fixed pulleys 3 and then is connected with the weight 5. The two fixed pulleys 3 are spaced at a certain distance to prevent the heavy hammer 5 from colliding with the tensioning roller 2, and also prevent one section of the tensioning rope 4 connected with the force application unit 5 from being accidentally wound with one section of the tensioning rope 4 connected with the tensioning roller 2 to cause the failure of the tensioning device.
Further, the tensioning device comprises a guide mechanism, on which the tensioning roller 2 is mounted so as to be movable along the guide mechanism. The tightening roller 2 is restrained by the guide mechanism and will stably move along the guide mechanism without shaking.
Further, the guide mechanism includes a guide bar 6 and a slider 7, the guide bar 6 is vertically disposed between the first horizontal portion 83 and the second horizontal portion 84, and both ends of the guide bar 6 are fixed to the first horizontal portion 83 and the second horizontal portion 84, respectively. The slide block 7 can move along the guide rod 6, the tensioning mechanism is fixed on the upper part of the slide block 7, and the tensioning roller 2 is fixed on the lower part of the slide block 7. The sliding block 7 is provided with a claw-shaped or annular structure which is clamped or sleeved on the guide rod 6, so that the sliding block 7 can stably move under the limit of the guide rod 6. The guide mechanism is simple in structure and good in stability. In other embodiments, other configurations of existing guide mechanisms may be used.
In the present embodiment, the head or tail of the conveyor belt 100 enters the apparatus frame 8 from the second upright portion 82 toward the first upright portion 81, so the distance between the guide bar 6 and the first upright portion 81 is smaller than the distance between the guide bar 6 and the second upright portion 82.
Further, in the embodiment, the redirection roller 1 and the tensioning roller 2 are both realized by hollow rollers, so that the device is light in weight and low in cost. In other embodiments, the redirecting roller 1 and the tensioning roller 2 may also be solid.
When the tensioning device is used, the tensioning device is fixedly arranged at the head or the tail of the belt conveyor, the tensioning roller 2 is positioned at the position, closest to the conveyor, of the stroke of the tensioning roller 2 (namely, the lowest end of the guide rod 6), then the head or the tail of the conveyor belt 100 is redirected by the redirection roller 1 and then sleeved on the tensioning roller 2, and the weight of the weight 5 is adjusted, so that under the tension action of the weight 5, the tensioning roller 2 is pulled by the tensioning rope 4 to move to the position, farthest from the conveyor, of the stroke of the tensioning roller 2 (namely, the highest end of the guide rod 6), and the conveyor belt 100 is tensioned.
The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the invention.
