Abstract

The utility model discloses a coming-off preventing device of an internal combustion locomotive hook flat cotter and belongs to the technical field of internal combustion locomotives. The coming-off preventing device can support a flat cotter and prevent a locomotive hook head from separating from a hook tail frame when a retaining pin is abraded excessively, fractures and comes off. The coming-off preventing device comprises a retaining pin protecting sleeve, a small U-shaped clamp and a large U-shaped clamp. At utilization time, the retaining pin sequentially penetrates through a side wall of a flat cotter installation seat, a retaining pni installation hole, the retaining pin protecting sleeve, the other side wall of the flat cotter installation seat, and another retaining pin installation hole. The large U-shaped clamp is located under the small U-shaped clamp. The side wall, without a through hole, of the large U-shaped clamp is closely attached to the end face of the square head of the retaining pin. The bottom face of the large U-shaped clamp is closely attached to the bottom face of the small U-shaped clamp and penetrates through a bolt installation hole, a groove-shaped hole and a bolt and then is connected with the bottom face of the small U-shaped clamp in a fastening mode. According to the coming-off preventing device, on the condition that original functions of a locomotive hook are not influenced, the large U-shaped clamp and the small U-shaped clamp are used for supporting the flat cotter safely, so that the problem of coming-off of the flat cotter due to failures of the retaining pin is solved, and the purpose of safe travelling is achieved.

Description

Diesel locomotive hitch cotter pilotage anti-drop device
Technical field
The utility model relates to diesel locomotive, specifically a kind of diesel locomotive hitch cotter pilotage anti-drop device.
Background technology
Hitch is diesel locomotive draw gear important component part, and the rear portion of hitch is called hook tail, opens vertical cotter pin hole on hook tail, cotter pilotage is installed, to be connected with hook tail frame.Because the retaining pin abrasion of coupler yoke key are exaggerated, breaking releasing, cause cotter pilotage to come off, hitch pull-out, affects traffic safety, causes rolling stock off-line or disturbing accident.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides that one can be exaggerated in retaining pin abrasion, during breaking releasing, hold cotter pilotage, prevents the diesel locomotive hitch cotter pilotage anti-drop device that hitch gib head is Fen Li with hook tail frame.
The utility model is achieved through the following technical solutions: a kind of diesel locomotive hitch cotter pilotage anti-drop device, comprises retaining pin protecting sleeve, little U-shaped card and large U type card; Described little U-shaped card two side has symmetrical retaining pin mounting hole, and little U-shaped card has bolt mounting holes on bottom surface; Described large U type card one sidewall has through hole, and large U type card has grooved hole on bottom surface; In use, retaining pin is successively through cotter pilotage mount pad one sidewall, a retaining pin mounting hole, retaining pin protecting sleeve, another sidewall of cotter pilotage mount pad and another retaining pin mounting hole; Described large U type is positioned in little U-shaped card below, and large U type card is closely connected without sidewall and the retaining pin square toes end face of through hole, and large U type card bottom surface and little U-shaped card bottom surface are closely connected and be fastenedly connected by bolt mounting holes, grooved hole and bolt and little U-shaped card bottom surface.
It is further: described retaining pin protecting sleeve is cylinder barrel shaped, and its internal diameter is a bit larger tham retaining pin diameter.
On described little U-shaped card bottom surface, longitudinally have two bolt mounting holes.
On described large U type card bottom surface, longitudinally have two grooved holes; Distance between distance and two bolt mounting holes between two described grooved holes equates.
The utility model, in the situation that not affecting locomotive coupler original function, is used large and small U-shaped card safety to hold cotter pilotage, prevents cotter pilotage that retaining pin fault the causes problem that comes off, and reaches the object of safe driving.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is little U-shaped card structure schematic diagram;
Fig. 3 is the birds-eye view of Fig. 2;
Fig. 4 is large U type card card structure schematic diagram;
Fig. 5 is the birds-eye view of Fig. 4.
In figure: 1, cotter pilotage; 2, cotter pilotage mount pad; 3, retaining pin; 4, little U-shaped card; 41, retaining pin mounting hole; 42, bolt mounting holes; 5, large U type card; 51, through hole; 52, grooved hole; 6, retaining pin protecting sleeve; 7, bolt.
The specific embodiment
Be below a specific embodiment of the present utility model, now by reference to the accompanying drawings the utility model be described further.
As shown in Figures 1 to 5, a kind of diesel locomotive hitch cotter pilotage anti-drop device, comprises that internal diameter is a bit larger tham retaining pin 3 diameter circle tubular retaining pin protecting sleeves 6 and large and small U-shaped card 5,4; Little U-shaped card 4 two sides have symmetrical retaining pin mounting hole 41, longitudinally have two bolt mounting holes 42 on its bottom surface; Large U type card 5 one sidewalls have through hole 51, and the distance longitudinally having on its bottom surface between distance and two bolt mounting holes 42 between grooved hole 52,52, two, two grooved holes equates.
No. 20 band steels of large and small U-shaped card 5,4 materials'use, burring, plating zinc on surface processing; During installation, for after avoiding retaining pin 3 to remove, cotter pilotage 1 falls naturally, causes personal injury and accessory damage, first dismantles retaining pin 3; Little U-shaped card 4 and retaining pin protecting sleeve 6 are put into cotter pilotage 1 lower position, retaining pin 3 is passed to cotter pilotage mount pad 2 one sidewalls, a retaining pin mounting hole, retaining pin protecting sleeve 6, cotter pilotage mount pad 2 another sidewalls and another retaining pin mounting hole successively.Then in retaining pin 3 ends, add spring chair, fastening mounting nuts, construction opening pin, spring cotter angle is greater than 60 °.Large U type card 5 is placed on to little U-shaped card 4 belows, and large U type card 5 is closely connected without sidewall and the retaining pin 3 square toes end faces of through hole 51, then in bolt mounting holes 42 and grooved hole 52, penetrates successively two M8 hold-down bolts, add spring chair, fastening mounting nuts, and install spring cotter additional, spring cotter angle is greater than 60 °.M8 hold-down bolt penetrates from top to bottom, nut and spring cotter below.After installing, check comprehensively, guarantee that the each portion of diesel locomotive hitch cotter pilotage anti-drop device is in good condition, solid and reliable.
