Description

A kind of attachment means
Technical field
The present invention relates to a kind of attachment means, more particularly to a kind of rotatable attachment means.
Background technology
In some structural tests, because experiment or in-site installation need, the hydraulic cylinder of a part of load(ing) point generally away from Separating test part remote position applies load.The equipment connection mode of distance test (DT) part load(ing) point farther out is at present:Hydraulic cylinder+bis- Ear+steel wire rope+ears+sensor+testpieces.Because the connected mode of hydraulic cylinder piston rod and ears, ears and sensor is equal For threaded connection, when hydraulic cylinder tenses these connection equipment, steel wire rope can have very much along loading line of force rotation, threaded connection equipment May be because steel wire rope to be from virtual connection or disengagement is transferred, this brings great potential safety hazard to experiment.
The content of the invention
(1) goal of the invention
It is an object of the invention to provide one kind in structural test, steel wire is connected to prevent from testing load(ing) point in loading procedure Restrict from a kind of simple and reliable spinning attachment means for transferring to cause other threaded connection equipment mutually to disengage and design, due to It discharges itself axial rotation free degree so that moment of torsion caused by steel wire rope rotation eliminates at the attachment means, has evaded spiral shell Line connects equipment because steel wire rope transfers the risk of disengagement certainly.
(2) inventive technique solution
The technical scheme of the invention is:
A kind of attachment means, it is characterised in that including bump joint (1), fixing bolt (2), double-direction thrust ball bearing (4), axle sleeve (5), valve body (6), locking nut (7), Step Shaft (8), adapter (9), caging bolt (10);
Valve body (6) is the cylinder that top and bottom are open, and valve body (6), which is axially inside provided with, runs through valve body upper and lower surface Step cavity, including the big footpath cavity (6-1) on top and the path cavity (6-2) of bottom;
Step Shaft (8) upper end is ledge structure (8-1), and lower end is male connection (8-2), in male connection (8-2) Meta is equipped with mounting hole;
Double-direction thrust ball bearing (4) is axially mounted in big footpath cavity (6-1), and double-direction thrust ball bearing (4) includes upper Plate (4-1), intermediate plate (4-2) and lower plate (4-3);
Ledge structure (8-1) external diameter is more than the bearing hole internal diameter of intermediate plate (4-2) position, while is less than upper plate (4-1) position The bearing hole internal diameter put, step end face and intermediate plate (4-2) upper surface of ledge structure (8-1);Ledge structure (8-1) is thick Degree is slightly less than the distance between intermediate plate (4-2) upper surface and upper plate (4-1) upper surface, and the upper surface of ledge structure (8-1) hangs Sky, male connection (8-2) passes through bearing hole, and is stretched out from the opening of path cavity (6-2) lower surface;
Axle sleeve (5) one end contacts with intermediate plate (4-2) lower surface, and the other end is by being installed in path cavity (6-2) Axle sleeve (5) is fixed on Step Shaft (8) by locking nut (7);Now axle sleeve (5), locking nut (7) by Step Shaft (8) with Between plate (4-2) it is locked, Step Shaft (8) can pass through double-direction thrust ball bearing (4) arbitrarily rotate.
Bump joint (1) is connected by fixing bolt (2) in the form of standard flange with valve body (6) upper surface, while flange Upper plate (4-1) upper surface is withstood in joint (1) ring flange lower surface, gives double-direction thrust ball bearing (4) certain assembly pretightening Power;Bump joint (1), fixing bolt (2) are axially locked with double-direction thrust ball bearing (4) by valve body (6).
Adapter (9) is connected through a screw thread with male connection (8-2), and passes through the caging bolt (10) through mounting hole Adapter (9) and male connection (8-2) relative position are fixed.
Further, in addition to pad (3), pad (3) is set between fixing bolt (2) and valve body (6) upper surface.
Further, bump joint (1) upper end is monaural structure, and lower end is standard flange dish structure, and circumferentially array has Fixing bolt mounting hole.
(3) have the advantage that compared with prior art or good effect
The attachment means have advantages below:
A) attachment means of the present invention are as one of experiment load(ing) point connection equipment, installed in steel wire rope both ends so that steel wire Moment of torsion caused by rotation is in the adapter (9) by mutually being fixed with Step Shaft (8) and the flange fixed with valve body (6) when rope tenses The relative rotation of joint (1) and discharge, evaded threaded connection equipment due to steel wire rope from then disengage risk, mounting process Simply, it is practical;
B) attachment means both ends monaural type of attachment replaces with to flange etc. is other to be fixedly connected with form, attachment means can be held By tension and compression bidirectional load, there can be wider array of application.

Fig. 2 is the structural representation of double-direction thrust ball bearing 4;
Fig. 3 is the structural representation of valve body 6;
Fig. 4 is the structural representation of Step Shaft 8;
Embodiment
Fig. 1 is the most preferred embodiment of the attachment means, it is characterised in that including bump joint 1, fixing bolt 2, Bidirectional pulling Power ball bearing 4, axle sleeve 5, valve body 6, locking nut 7, Step Shaft 8, adapter 9, caging bolt 10;
Valve body 6 is the cylinder that top and bottom are open, and valve body 6 is axially inside provided with the platform through valve body upper and lower surface Rank cavity, including the big footpath cavity 6-1 on the top and path cavity 6-2 of bottom;
The upper end of Step Shaft 8 is ledge structure 8-1, and lower end is male connection 8-2, and male connection 8-2 interpositions are equipped with Mounting hole;
Double-direction thrust ball bearing 4 is axially mounted in big footpath cavity 6-1, double-direction thrust ball bearing 4 include upper plate 4-1, Intermediate plate 4-2 and lower plate 4-3;
Ledge structure 8-1 external diameters are more than the bearing hole internal diameter of intermediate plate 4-2 positions, while less than the axle of upper plate 4-1 positions Bearing bore internal diameter, ledge structure 8-1 step end face and intermediate plate 4-2 upper surfaces;Ledge structure 8-1 thickness is slightly less than centre The distance between plate 4-2 upper surfaces and upper plate 4-1 upper surfaces, ledge structure 8-1 upper surface is hanging, and male connection 8-2 is worn Bearing hole is crossed, and is stretched out from the opening of path cavity 6-2 lower surfaces;
The one end of axle sleeve 5 contacts with intermediate plate 4-2 lower surfaces, and the other end passes through the locking screw that is installed in path cavity 6-2 Axle sleeve 5 is fixed on Step Shaft 8 by mother 7;
Bump joint 1 is connected by fixing bolt 2 in the form of standard flange with the upper surface of valve body 6, while the method for bump joint 1 Withstand upper plate 4-1 upper surface in blue disk lower surface;
Adapter 9 is connected through a screw thread with male connection 8-2, and will be transferred by the caging bolt 10 through mounting hole First 9 fix with male connection 8-2 relative positions.
Also include pad 3, pad 3 is set between fixing bolt 2 and the upper surface of valve body 6.
The upper end of bump joint 1 is monaural structure, and lower end is standard flange dish structure, and circumferentially array has fixing bolt installation Hole.Attachment means adapter 9 of the present invention passes through 4 axially opposed rotation of double-direction thrust ball bearing, attachment means with bump joint 1 As experiment load(ing) point connection equipment and when being installed on steel wire rope both ends, the equipment connection mode of load(ing) point is by hydraulic cylinder+bis- Ear+steel wire rope+ears+sensor+testpieces be changed to hydraulic cylinder+ears+attachment means+steel wire rope+attachment means+ears+ Sensor+testpieces, moment of torsion caused by rotation discharges at attachment means when now steel wire rope tenses, and can evade threaded connection and set The standby risk for transferring disengagement certainly due to steel wire rope.
