Operation principle：
First when drawing the larger round shape workpiece shaft coupling clutch being such as sleeved on axis or the belt pulley being on axis, gear,
According to the isodiametric size of clutch, position of the big pull rod 6 on cantilever 4 is adjusted by the 3rd axis pin 23, is allowed on big pull rod 6
The outer diameter of big pulling claw 6-1 and clutch matches, and so adapts to the clutch of different-diameter, allow machinery draw the applicability of horse compared with
It is good, then by the position for the axis for being in clutch center, adjust big pull rod 6 and allow big pulling claw 6-1 in the spacing of the axial direction of cantilever 4
Length can touch the rear end of clutch, big pulling claw 6-1 is blocked to the rear end of clutch, spring 8 is at this moment compressed and heads on backrest
The axis in center is taken turns, horse is drawn to be supported under the elastic force of compression spring 8 entire machinery, without several personal cooperation feelings simultaneously
Under condition, machinery draws horse just to be fixed well by advance support, saves human resources, easy to operate, more time saving and energy saving, then
The top cone head part of leading screw 1 is headed on by axis on the inside of clutch by 2 rotating threaded shaft 1 of swivel head, then swivel head is turned with spanner
2, leading screw 1 moves forward, and clutch is chosen by big pull rod 6 by big pulling claw 6-1；Choose bearing on axis or single-stage,
During the impeller of multistage pump, exist since bearing or impeller are in the inside of equipment, between such bearing and impeller and equipment smaller
Spacing, the big pulling claw 6-1 on big pull rod 6 is not placed into since size is larger, this is just needed using on the inside of rotation slot 6-2
Lower link bar 9, allows lower link bar 9 parallel with big pull rod 6 first and the spacing between bearing or impeller and equipment moves, and when contact is small
Pulling claw 11 can be rotated by complete top convolution in income slot 14, and when small pulling claw 11 is in bearing or impeller rear end, small pulling claw 11 is existed
Ejected under the elastic force of spring 15, bearing or impeller blocked, with choose clutch when equally turn leading screw 1 and chosen,
During choosing, support backplate 12 plays the role of the small pulling claw 11 of support, increases so support backplate 12 is adopted forever thicker steel and made
Its strong intensity, can be in rotation slot 6-2 when the withdrawal of small pulling claw 11 goes also to be not placed into the spacing of bearing or impeller and equipment room
It is interior that lower link bar 9 is rotated into 180 degree, allow the kerve 13 on smaller pull head 10 put in the spacing of bearing or impeller and equipment room by its
It is stuck in and chooses, by the way that rotatable pull rod 9 is set to adapt to be chosen and its smaller part of external spacing, the model used
It encloses more extensively, so for the different size of drawing horse that need to be dismantled part and just be without the use of different size, versatility is more preferable, carries
It is more convenient；Due to drawing horse, leading screw is easy to wear in use, regularly can inject butter, butter by oil filler point 20
Stream flowing full enters straight slot 17, and butter is uniformly coated on its screw thread when rotating threaded shaft 1, and playing lubrication prevents the work of abrasion
With turning more quick and convenient.
The basic principles, main features and advantages of the invention have been shown and described above, and the technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe the originals of the present invention
