Description
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.
