Abstract
The utility model relates to a steel wire rope locking and locating device, which is characterized in that axial locking is applied on a knuckle bearing for suspending a steel wire rope at the inner sides of end plates at the two sides of a mounting seat through locating sleeves at two sides so as to complete the locating of the steel wire rope relative to a bolt, eliminate the axial shifting of the steel wire rope under the high-speed driving state of a vehicle, and reduce noise. The steel wire rope locking and locating device consists of the mounting seat connected with a car body, and the steel wire rope penetrates through bolts suspending on the two end plates at the two sides of the mounting seat. The steel wire rope is radially suspended on the bolt by the knuckle bearing; a first locating sleeve and a second locating sleeve are symmetrically sheathed on the bolt, at the inner sides of the end plates at two sides of the mounting seat and on the two transverse sides of the knuckle bearing; and fastening nuts are connected on the bolt and at the outer side of the second locating sleeve. When the fastening nuts are pressed, the two locating sleeves can be axially compressed, thereby realizing the axial locking on the inner ring of the knuckle bearing, effectively preventing the axial shifting of the steel wire rope and further decreasing the noise during the high-speed driving process of a vehicle.
Description
Technical field
The utility model relates to a kind of Steel wire rope lock clamping and positioning device that is used for guideway vehicle, belongs to mechanical manufacturing field.
Background technology
The guideway vehicle speed per hour of present domestic main line railway reached 380 kilometers and more than, the safe precaution measure that correspondingly requires the structure between car body and the bogie truck to have higher level.
When vehicle is crossed bent angle or deadlight load at a high speed and changed greatly, be generally and prevent between car body and the bogie truck excess in displacement to take place and be provided with to assist and be connected steel rope.Promptly overcharge when big when air bellow,, a vertical steel rope that connects car body and bogie truck is set at large, as the means of remedying under the abnormal condition temporarily for preventing car body abnormal ascending or the deflection phenomenon of toppling.
Steel rope used in the prior art is to be hung on the bolt that runs through mount pad both sides end plate, and this type of mounting structure mainly exists following technological deficiency and weak point:
Lack at wirerope axis to the locking positioning function, owing to jolt or cross bent angle, end float misalignment easily takes place and produces big noise in steel rope in the high vehicle speeds process, takes environment thereby influence to the car body internal delivery under the car.
The bolt of being hung does not have good horizontal anti-shear ability, and the threaded portion of bolt is vulnerable to the vertical impact power of steel rope and causes fatigue strength to rise, bolt shortening in service life.
In view of this special present patent application that proposes.
The utility model content
Steel wire rope lock clamping and positioning device described in the utility model, its design goal is to solve the problem of above-mentioned prior art existence and applies axial locking in the inboard of mount pad both sides end plate, by the both sides locating bush to the oscillating bearing of hanging steel rope, to finish steel rope location, eliminate steel rope end float misalignment, reduction noise under the high vehicle speeds state with respect to bolt.
Another design goal is, the bolt that adopts round pin formula structure is to make it possessing higher horizontal anti-shear ability, and the fatigue strength that reduces bolt is to prolong its service life.
For realizing above-mentioned design goal, described Steel wire rope lock clamping and positioning device mainly includes:
Be connected in the mount pad of car body, wire rope hanging is in the bolt that runs through mount pad both sides end plate.
The difference with the prior art part is that steel rope radially is hung on bolt by oscillating bearing;
On bolt, the inboard of mount pad both sides end plate and the both lateral sides of oscillating bearing, be arranged with first locating bush and second locating bush symmetrically;
On bolt, the outside of second locating bush, be connected with clamp nut.
As above-mentioned basic scheme feature, 2 locating bushs of symmetry are set in the both lateral sides of oscillating bearing, when holding out against, clamp nut can axially compress these 2 locating bushs, thereby realize axially locking the inner ring of oscillating bearing, promptly whole steel rope is played the axial locking positioning function, prevent steel rope generation end float misalignment effectively and reduce to be created in thus noise in the high vehicle speeds process.
For avoiding because of bolt is subjected to the lateral shear effect that the vertical impact power of steel rope forms, the further innovative approach that can take is, described bolt is the round pin structure, only be in the locating bush outside, the position that connects clamp nut is provided with screw thread.
The round pin bolt that is adopted has significantly laterally anti-shear ability than plain bolt, because the connecting portion of bolt and the both sides end plate of 2 locating bushs, mount pad is not provided with screw thread, these positions can not cause the fatigue strength rising because of cross shear.And the outside that threaded position is positioned at locating bush and mount pad is set, be subjected to again less than the cross shear effect.
For balanced and improve the locking application force that clamp nut acts on locating bush, can be at the flexible packing ring of lining on the bolt, between second locating bush and the clamp nut.
For preventing that clamp nut locking back is around bolt generation axial rotation, avoid that above-mentioned locking positioning device takes place loosening in the high vehicle speeds process, described clamp nut has several axial location grooves, and at least one spring cotter runs through in the knock hole on positioning groove and the inserting bolt.
When clamp nut during around bolt generation axial rotation trend, the vertical backstop of spring cotter is in the positioning groove of clamp nut and play position-limiting action.
Content to sum up, the advantage that the utility model Steel wire rope lock clamping and positioning device has is:
1, realizes the axial locking of steel rope oscillating bearing, can eliminate the noise that causes thus to avoid steel rope generation end float misalignment effectively.
2, adopt the round pin bolt to make it possessing higher horizontal anti-shear ability, reduce the fatigue strength of bolt and increase the service life.
