Abstract
The invention belongs to the field of maintenance tools for demounting belt pulleys. An original three-jaw tensioner (puller) is changed into a U-shaped card, the original three-jaw tensioner is stressed at three outside points, and the U-shaped card is stressed on an inner plane, so that the original tensioner which cannot be fixed is changed into a tensioner capable of being fixed.
Description
Technical field
The present invention is a kind of maintenance tool field of dismantling belt pulley, also cries and draws horse.
Technical background
How inconvenient current three-jaw pulling force (drawing horse) commonly used has, and the inaccurate power-assisted of triangle is excessive, easily draws bad Cao limit; When the spiral power-assisted is large, fixing pulling force, moment of torsion is low, is not durable, and valency processed is high.
The invention technology
The present invention draws original three-jaw 3 outsides on limit stressed, and changing U-shaped card into is that inner plane is stressed, has added horizontal socket on U-shaped slide, fixes pulling force.
The specific embodiment:
To achieve these goals, can watch accompanying drawing:
1. U-shaped slide; 2. the fixing horizontal socket of pulling force; 3. hold-down nut; 4. moving screw; 5. the horizontal socket used of drive screw; 6. top before screw rod.In use, U-shaped card empty set on available U-shaped card is on motor shaft, the card plane leans against on the medial surface of belt pulley, the top aligning motor shaft of moving screw centre bore, drive moving screw, because U-shaped card is welding on one of U-shaped slide, the other end be by card and fixedly mother be connected as a single entity, the U-shaped card in top inside top is pulled outwardly, thereby complete, pulls down belt pulley.
2. be to insert in socket with crowbar, strength of using the earth on the ground fixes, and is available everywhere.5. use crowbar to insert in socket on figure and make boosting-rod, durable in use, cheap, easy to use.
Claims (4)
1.U type card.
2.U type card cylinder connects.
3. laterally socket is fixed.
4. laterally socket drives.
