Abstract
The utility model relates to a fastening device with controllable pre-fastening force, which comprises a strong support board, a pre-tightening force nut and a special spanner, wherein the strong support board is provided with a reinforcing rib; the middle part of the strong support board is bulged; the perifhery of the strong support board is a flat bottom; the bulging parts in the middle part and the flat bottom have arc transition; the periphery or the upper flat plane of the pre-tightening force nut is additionally provided with a convex pin; the special spanner is additionally provided with a groove or a hole which corresponds to the convex pin of the pre-tightening force nut. The utility model has the advantages of simple installation and operation. Besides, the fracture of the convex pin is the sign that the utility model is intactly installed when the spanner is fastened on the pre-tightening force nut. Thereby, the installation quality is easy to guarantee. Besides, the utility model can be visually tested, and can be matched and fastened to use with various structural members, such as screw bolts, threaded rods, anchor rods, etc. The strong support board has a high bearing capability.
Description
The utility model belongs to fastener, with supporting fastening uses of structural member such as bolt, screw rod, anchor poles, is specially adapted to various anchor poles on the mine are installed, and is easy and simple to handle, installs firmly.
Have now with matching used fasteners of structural member such as bolt, screw rod, anchor poles and remain in weak point:
1) supporting plate or pad generally are steel supporting plate or the casting supporting plates of not being with reinforcement, and bearing capacity is big inadequately.
2) use standard nut, pretightning force is wayward, and back pretension quality is installed can't macroscopic examination, easily has hidden danger.
The present utility model purpose in order to overcome the prior art weak point, designs that a kind of bearing capacity is big, the controllable fastener of pretightning force.
The present utility model purpose is realized by following technical scheme, and is as follows below in conjunction with the description of drawings that embodiment provides:

Detailed description of main elements: hole (6) on groove (5), the wrench on the protruding pin (4) of powerful supporting plate flat (1), intermediate projections part (2), reinforcement (3), nut, the wrench.
The controllable fastener of the utility model pretightning force comprises powerful supporting plate, pretightning force nut and special-purpose wrench, and its architectural feature is:
1, set up reinforcement (3) on the powerful supporting plate, middle projection is flat (1) on every side, Middle bossing (2) and flat (1) are by arc transition. Projection in the middle of reinforcement (3) is located at Partly on (2) or flat (1), or on middle bossing (2) and flat (1), such as Fig. 1-3 Shown in.
2, protruding pin (4) is set up on the periphery of pretightning force nut or last plane, shown in Fig. 4-8.
3, personality board is set up and the corresponding groove of the protruding pin of pretightning force nut (4) (5) or hole (6) on hand, shown in Fig. 9-12.
As follows below in conjunction with description of drawings:
Powerful supporting plate profile is polygon, circle, and intermediate projections part (2) shape can be terrace with edge, round platform, sphere etc., arrangements such as reinforcement (3) can be radially, annular, and R is general, and 5-20mm is advisable.This powerful supporting plate is than the supporting plate bearing capacity with reinforcement (3) is not big.If adopt steel plate cold moudling, cold-press process also can be strengthened the bearing capacity of supporting plate.Fig. 1-3 is that the powerful supporting plate of the utility model is implemented illustration, and intermediate projections part (2) is a sphere, establishes three radially reinforcements (3) on the sphere, adopts steel plate cold moudling.
The profile of pretightning force nut is not limit, and protruding pin (4) can or be assembled with the nut one-shot forming, and protruding pin (4) size is directly proportional with the pretightning force size, according to the pretightning force size requirements, makes the protruding pin (4) of different size specification, and general 1 of protruding pin (4) is advisable.
Fig. 4-6 is the utility model pretightning force nut embodiment 1 figure, sets up a protruding pin (4) on nut circumference, protruding pin (4) can with the nut one-shot forming.
Fig. 7-8 is the utility model pretightning force nut embodiment 2 figure, an assembling protruding pin (4) on plane on the common hex nut.
Fig. 9-10 is special-purpose wrench embodiment 1 figure, be on the periphery with the supporting use of pretightning force nut of protruding pin (4).
Special-purpose wrench embodiment 2 figure of Figure 11-12 are the supporting uses of pretightning force nut for the protruding pin of last planar band (4).
The outstanding advantage of the controllable fastener of the utility model pretightning force is:
1, fitting operation is simple, and installation quality easily guarantees, but and visual test.After structural members such as bolt or screw rod or anchor pole had been adorned, on powerful supporting plate pad, the pretightning force of screwing on nut used special-purpose wrench that protruding pin (4) fracture of pretightning force nut screwing clamping to nut promptly installed again.The protruding pin (4) that uses this device to be fastened to nut is fractured into installs intact sign, thereby installation quality is guaranteed, and easily visual test, thereby has avoided hidden danger.
2, powerful supporting plate bearing capacity is big.Cause has been set up reinforcement (3) and intermediate projections part (2) and flat (1) with arc transition, thereby has improved supporting plate intensity.This powerful supporting plate particularly suitable is to the installation of mine anchor pole.
3, processing is simple, suitable produces in enormous quantities.Can adopt steel plate cold moudling as powerful supporting plate, the pretightning force nut can be according to the pretightning force size requirements for another example, and the protruding pin (4) of design different size is produced and made serial pretightning force nut product.
4, applied range, can with the supporting fastening uses of structural member such as various bolts, screw rod, anchor pole, be a kind of novel controllable fastener of pretightning force simple in structure.
