Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
According to embodiment of the present utility model, there is provided a kind of pulley extractor.
As shown in Figure 1-2, it is left in the framework 1 according to a kind of pulley extractor of the utility model embodiment, including framework 1
Right both sides are symmetrically arranged with bar-shaped trough 2, and at least two pass through the pull bar 3 of the bar-shaped trough, and the lower end of pull bar 3 is provided with L-shaped card
Pawl 4, the middle part of framework 1 are also extended through provided with push rod 5, and the upper end of push rod 5 is provided with rotary handle 6, and the bottom of push rod 5 is set
Top 7 are equipped with, is disposed with support block 8, elastomer 9 and two telescopic grippers 10 inside the push rod 5 from top to bottom,
The outside of elastomer 9 is provided with baffle plate 12, and the outside bottom of push rod 5 is provided with two outlets matched with the gripper 10
13；The top of support block 8 is fixedly connected with rotary handle 6, by the rotation of rotary handle 6 support block 8 can be driven upward
Or move downward, and then elastomer 9 is loosened or extruded, gripper 10 is retracted or leant out from outlet 13 under the drive of elastomer 9.
Dismountable bolt 11 is provided between support block 8 and the outside of the push rod 5, certain position-limiting action is played to support block 8.It is described
Top 7 tip is enclosed with composite polycrystal-diamond 14, and described top 7 are provided with radiating groove at equal intervals with the surface of push rod 5
15。
By means of above-mentioned technical proposal, by setting bar-shaped trough 2 in framework 1, can be adjusted according to the position of bearing
Relative distance between two pull bars 3；By setting dismountable bolt 11, Ke Yigen between on the outside of support block 8 and push rod
Choose whether to use gripper 10 according to needs, when needing to increase grip, rotation can be passed through with demounting bolt 11 when increasing contact area
