When mobile, because movable block 9 and the sliding of hollow frame 10 connect, now movable block 9 can enter line slip in hollow frame 10.And then protect
Card movable block 9 will not drive the tensioning wheel 11 being fixedly connected with hollow frame 10 to move up and down when moving in the horizontal direction.Above-mentioned fortune
Dynamic process is moved back and forth and back and forth carried out with movable block 9.
When the degree of wear is lighter after a long time use for transmission belt 14, technical staff can be adjusted by another way and is driven
With the tensioning degree between 14 and drive.Further, as shown in figure 3, the side of supporting plate 2 is hinged with rotor plate 16, turn
The side of dynamic plate 16 is fixedly connected by bolt with motor 12.The one end of rotor plate 16 away from pin joint is fixedly connected with two
Individual separate fixed block 17, cylinder 18 is rotatably connected between two fixed blocks 17.The side of cylinder 18 is equipped with screw mandrel
19, one end of screw mandrel 19, which is fixedly connected with, rotates handwheel 20.Positioned at cold headers body 1 close to the side of supporting plate 2 be provided with
The support chip 21 that supporting plate 2 is parallel to each other, the side of support chip 21 are fixedly connected with cold headers body 1.The side of support chip 21
It is fixedly connected with and is relatively fixed piece 22 with the above-mentioned position of fixed block 17, bearing column 23, axle is provided between two stators 22
The side of platen 23 socket-connects with screw mandrel 19.
Technical staff is rotated by rotating handwheel 20, and then can drive the cylinder 18 being socketed therewith.Due to cylinder 18
Both sides are rotatablely connected with fixed block 17, and then cause cylinder 18 from being rotated with screw mandrel 19 simultaneously.Therefore, cylinder 18 can be with
Moved on screw mandrel 19 along the direction of axis line of screw mandrel 19.By changing the relative position between cylinder 18 and screw mandrel 19, enter
And rotor plate 16 is caused to rotate minute angle around pin joint.When transmission belt 14 after a long time use, the degree of wear it is more micro-
Hour, by rotating the use of handwheel 20, can rotate backward the motor 12 being fixedly connected with rotor plate 16 minute angle,
Because bearing column 23, cylinder 18 are all rotatablely connected, when rotor plate 16 rotates minute angle around pin joint, bearing column 23 and post
Body 18 all coordinates rotor plate 16 to carry out rotation certain amplitude.So that small transmission wheel 13 and the center spacing of large drive wheel 15 are in certain journey
It is elongated on degree, so as to ensure to be in tight state between transmission belt 14 and drive, avoid the generation of skidding.
When rotation handwheel 20 stops operating, certain gradient between cylinder 18 and screw mandrel 19 be present.Can preferably it protect
Card cylinder 18 had not only been in mutual clamped condition with screw mandrel 19 but also had been in threaded connection state.And then improve the stabilization of rotor plate 16
Property, it ensure that the stability for the motor 12 being fixedly connected with rotor plate 16.Rotor plate 16 is being driven by rotating handwheel 20
When being rotated around pin joint, in actual mechanical process, only it is applicable and the rotation in small angle range.It is adapted to transmission belt 14 to exist
For a long time using the rear degree of wear it is relatively light in the state of operated.
