As preferably, described springing is three cluster springs.
As preferably, described telescopic is fixed with outer flat board, and described base is provided with and the described outer dull and stereotyped pilot bar coordinating.
As preferably, described pilot bar cross-sectional plane is rectangle.
Beneficial effect of the present invention is:
Simple in structure, easy to manufacture, can guarantee under the unforeseen circumstancess such as power-off, rail clamping device is firmly clamped in orbit, can not throw off.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.
Embodiment, see accompanying drawing 1, a kind of self-locking device for rail clamping device, comprise base 1, the fixed cover 201 being fixedly connected with described base 1, telescopic 207 and for driving described telescopic 207 to carry out the jacking system 208 of lifting, between described telescopic and described base, be provided with extension spring 209, jacking system can adopt cylinder or oil cylinder, wherein take cylinder as good, fixed cover is sleeved on the outside of screw mandrel in the future, screw mandrel 3 therefrom passes, described fixed cover 201 inside faces are provided with at least two radial grooves 202, be generally three, cross-sectional plane is rectangle or trapezoidal, in described radial groove 202, be provided with sliding panel 203, described sliding panel 203 inside faces are provided with negative thread 204, negative thread can with screw mandrel or worm mesh, in described radial groove 202, be provided with the springing 205 that described sliding panel 203 is inwardly promoted, springing generally adopts spring, quantity is 3-5, spring inwardly promotes sliding panel 203, simultaneously, described sliding panel 203 lower ends are connected with outward-dipping hang plate 206, 203 one-tenth 10-15 of described hang plate 206 and described sliding panel ° angle, described telescopic 207 is provided with the outer lateral incline with described hang plate 206 medial surface laminatings, the medial surface laminating of outer lateral incline and inclination, telescopic 207 can rise under the drive of cylinder, with an outer lateral incline, sliding panel is outwards promoted, overcome spring force slides in radial groove, negative thread and screw mandrel or worm screw throw off, screw mandrel or worm screw normal rotation, when power-off, the power of cylinder disappears, because be provided with extension spring 209 between base 1 and telescopic, so under the effect of extension spring and gravity, telescopic glides, under the effect of spring, sliding shoe inwardly slides, make negative thread and screw mandrel or worm mesh, realize locking.
Further, described telescopic 207 is fixed with outer dull and stereotyped 210, and described base 1 is provided with and described outer dull and stereotyped 210 pilot bars 211 that coordinate, and the cross-sectional plane of pilot bar is rectangle, can either lead, and can not rotate again.
