Abstract
The utility model relates to a machinery dismounting device technical field, especially an antiskid type draws horse. It includes the lead screw, draws the seat, transports persons or goods by cart and draw the claw, and the lead screw is inserted in the central authorities of drawing the seat, transports persons or goods by cart and connects the edge drawing the seat, draws the claw to connect at the end of transporting persons or goods by cart, is equipped with the protection pad on the lead screw, is equipped with on the protection pad and protects claw and locating piece. Protection pad the bottom of lead screw swivelling joint cover shape to set up the locating piece that protects claw and strong magnet material of the elastic expansion structure of symmetry respectively in the edge of protection pad and the bottom centre of a circle, messenger's lead screw and spool between set up firm relation of connection. The during operation earlier passes through the locating piece with the protection pad and adsorbs the top center at the axle, then adjusts the length of protecting the claw according to the radius of axle, closely detains at the edge of axle, forms the parcel structure, has further improved the connection steadiness, when the lead screw rotation, be only limited to fix on the sheath in, the counter shaft does not exert an influence to effectively avoid the slippage, improved the reliability of work.
Description
Technical field
The utility model relates to mechanical provision for disengagement technical field, and especially a kind of anti-slip type draws horse.
Background technology
In machinery industry, often relate to motor pulley, stator, rotor and the field-strip between various gear and axle in motor, need to use a kind of instrument being referred to as to draw horse.Form screw mechanism between its nut and screw mandrel, nut is fixed in main body, and after the front end of pulling claw is linked up with gear hook jail, turn screw mandrel makes its front end and is coupling tactile and continues forward to withstand axle, and wheel shaft can be made to be separated.Existing when drawing horse to work screw mandrel withstand on axle, lack firmly syndeton, during rotation, easy slippage, causes operation failure.
Utility model content
Fixing in order to overcome existing horse leading screw shortage of drawing, hold eely deficiency, the utility model provides a kind of anti-slip type and draws horse.
The utility model solves the technical scheme that its technical problem adopts: a kind of anti-slip type draws horse, comprise screw mandrel, pulling seat, transport persons or goods by cart and pulling claw, screw mandrel is inserted in the central authorities of pulling seat, transport persons or goods by cart and be connected to the edge of pulling seat, pulling claw is connected to the end of transporting persons or goods by cart, screw mandrel is provided with protection pad, and protection pad is provided with and protects pawl and locating piece.
According to another embodiment of the present utility model, it is hood-shaped for comprising protection pad further, is rotatably connected in the bottom of screw mandrel.
According to another embodiment of the present utility model, comprise that to protect pawl be elastic telescopicing rod further, be symmetrically distributed in the edge of protection pad.
According to another embodiment of the present utility model, comprising locating piece is further strong magnet, is arranged on the center of circle, bottom of protection pad.
The beneficial effects of the utility model are, be rotatably connected in the bottom of screw mandrel hood-shaped protection pad, and the locating piece protecting pawl and strong magnet material of symmetrical elastic extension structure is set respectively at the edge of protection pad and the center of circle, bottom, make between screw mandrel and axle, to set up firmly annexation.During work, first protection pad is adsorbed on the center of top of axle by locating piece, then regulate the length of protecting pawl according to the radius of axle, be closely buckled in the edge of axle, form package structure, further increase stable connection, when leading screw rotates, be only limited in sheath, axle do not had an impact, thus effectively avoid slippage, improve the reliability of work.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure, 1. screw mandrels, 2. pulling seat, 3. transport persons or goods by cart, 4. pulling claw, 5. protection pad, 6. protects pawl, 7. locating piece.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of anti-slip type draws horse, comprise screw mandrel 1, pulling seat 2, transport persons or goods by cart 3 and pulling claw 4, screw mandrel 1 is inserted in the central authorities of pulling seat 2, to transport persons or goods by cart 3 edges being connected to pulling seat 2, pulling claw 4 be connected to transport persons or goods by cart 3 end, screw mandrel 1 is provided with protection pad 5, and protection pad 5 is provided with and protects pawl 6 and locating piece 7.Protection pad 5, in hood-shaped, is rotatably connected in the bottom of screw mandrel 1.Protect pawl 6 for elastic telescopicing rod, be symmetrically distributed in the edge of protection pad 5.Locating piece 7 is strong magnet, is arranged on the center of circle, bottom of protection pad 5.
The protection pad 5 being rotatably connected hood-shaped in the bottom of screw mandrel 1, and the locating piece 7 protecting pawl 6 and strong magnet material arranging symmetrical elastic extension structure at the edge of protection pad 5 and the center of circle, bottom respectively, make to set up firmly annexation between screw mandrel 1 and axle.During work, first protection pad 5 is adsorbed on the center of top of axle by locating piece 7, then regulate the length of protecting pawl 6 according to the radius of axle, be closely buckled in the edge of axle, form package structure, further increase stable connection, when leading screw 1 rotates, be only limited in sheath 5, axle do not had an impact, thus effectively avoid slippage, improve the reliability of work.
