Example two
This embodiment is a further improvement over the previous embodiment: the adjusting part comprises a guide rod 21 arranged on the top wall of the box body 5, a left sliding block 22 is arranged on the guide rod 21 in a sliding mode, the left sliding block 22 is fixedly connected with a fixed cylinder 23, the top wall of the box body 5 is rotatably provided with a screw rod 9, a right sliding block 10 is arranged on the screw rod 9 in a threaded mode, and the right sliding block 10 is fixedly connected with the fixed cylinder 23.
The box 5 one side rotates and installs bull stick 13, and bull stick 13 penetrates box 5 interior one end and worm 12 fixed connection, worm wheel 11 with worm 12 meshing is installed to screw rod 9 bottom.
In this embodiment, when the tensioning component needs to be adjusted, the rotating rod 13 can be rotated, the worm wheel 11 and the worm 12 which are meshed drive the screw 9 to rotate, and then drive the right sliding block 10 to move upwards, and then drive the fixed cylinder 23 to move upwards, and then push the sliding plate 15 to move downwards along the sliding cavity 14 under the action of the tensioned chain 3, so that the elastic piece 16 is compressed, and then the elastic action of the elastic piece 16 on the tensioning wheel 6 is recovered, so that the tensioning component is recovered.
The working principle is that in the process that the chain wheel 2 drives the chain 3 to drive, the tensioning wheel 6 is meshed with the chain 3, and then the chain 3 is meshed and simultaneously rotates, when the chain 3 is worn out for a long time to lead to the side length of the chain 3, the elastic piece 16 rebounds along with rebound, so that the tensioning wheel 6 is always clung to the chain wheel 2, and the chain 3 is propped straight, so that the chain 3 is tensioned, and the automatic tensioning of the driving chain 3 is realized.
But with the continuous grow of wearing and tearing of chain 3, the spring also continuously kick-backs for elastic component 16 becomes longer gradually, makes slide 15 can be along smooth chamber 14 constantly upwards move, and the elasticity of elastic component 16 also becomes smaller gradually, and when the elasticity of elastic component 16 is insufficient to make take-up pulley 6 carry out tensioning to chain 3, the trigger piece 17 of slide 15 top both sides can support the touch-control switch 18 at smooth chamber 14 top both sides this moment, and then starts audible and visual warning light 20, provides the workman through audible and visual warning light 20 and need adjust the tensioning part or carry out the inspection to chain 3 and change, and then resumes the tensioning capacity of tensioning part.
When the tensioning part needs to be adjusted, the rotating rod 13 can be rotated, the worm wheel 11 and the worm 12 which are meshed drive the screw 9 to rotate, then the right sliding block 10 is driven to move upwards, then the fixed cylinder 23 is driven to move upwards, then the sliding plate 15 is pushed to move downwards along the sliding cavity 14 under the action of the tensioned chain 3, then the elastic piece 16 is compressed, and then the elastic action of the elastic piece 16 on the tensioning wheel 6 is restored, so that the tensioning part is restored.
When the chain 3 tensioning device is used, when the elastic piece 16 rebounds to the limit position, the warning part gives a warning at the moment to remind a worker to adjust the tensioning part, and the tensioning part can be adjusted through the arranged adjusting part, so that the tensioning part can continuously tension the chain 3, and meanwhile, the worker is also conveniently reminded of replacing the chain 3.
