Abstract
The utility model relates to a field is connected to coupling, hook tail frame, specifically is a big pivot angle coupling dropout prevention means. Big pivot angle coupling dropout prevention means includes coupling, hook tail frame, connecting pin, and the coupling passes through connecting pin swing joint with hook tail frame, and the downside of the corresponding connecting pin of hook tail frame passes through anti -drop board of bolted connection, and there is a recess position that the anti -drop board corresponds the connecting pin, and the connecting pin is circular shape round pin cap and the rectangle shank constitutes, pinhole and the cooperation of rectangle shank that hook tail frame is corresponding, and the horizontal plane cross section diameter of round pin cap is greater than the diagonal length of shank horizontal plane cross section. The utility model discloses simple structure, even under the coupling breaking occur condition, the coupling still can bear and have a device that prevents coupling longitudinal movement. Prevent the emergence of the smooth car accident of torpedo jar train.
Description
Technical field
The utility model relates to hitch, couple yoke connection area, specifically a kind of big swing angle hitch anti-drop device.
Background technology
Current Some Domestic smelter uses the 320 tons of torpedo type mixed iron cars installing big swing angle hitch, and the coupler device of 320 tons of torpedo type mixed iron cars is connected with the connecting pin of hitch by φ 61 × 320 with couple yoke.If during connecting pin fracture, connecting pin can come off and produce vehicle and slip car accident; If during connecting pin fracture, hitch can be produced and vertically moves, open hook shadoof and cause car accident of slipping.
Produce the reason of car coupler yoke fracture or draft key fracture, spare part foundry defect, utilization process impact reverse load impact frequently, heavy hook connect hang, curve connects to hang etc. and easily causes the initiation of rupturing suddenly of coupler and draft gear spare part to slip car accident.
Summary of the invention
Technical problem to be solved in the utility model is: when how to prevent connecting pin from rupturing, and connecting pin can come off and produce vehicle and slip car accident.
The technical scheme that the utility model adopts is: big swing angle hitch anti-drop device, comprise hitch, couple yoke, connecting pin, hitch and couple yoke are flexibly connected by connecting pin, the downside of the corresponding connecting pin of couple yoke is bolted one block of slip-off preventing plate, there is a groove position of the corresponding connecting pin of slip-off preventing plate, connecting pin is that circular pin cap and rectangle shank are formed, the pin-and-hole that couple yoke is corresponding coordinates with rectangle shank, and the horizontal surface cross-sectional diameter of pin cap is greater than the catercorner length of shank horizontal surface cross-sectional plane.
As a kind of optimal way: the groove of slip-off preventing plate is the rectangular recess that a level cross-sectionn size is identical with shank horizontal surface cross-sectional plane, below groove, there is a through hole.
The beneficial effects of the utility model are: the utility model structure is simple, even if under hitch generation crack conditions, hitch still can carry and have the device preventing hitch from vertically moving.Prevent the generation of the car accident of slipping of fish torpedo ladle train.

Fig. 2 is slip-off preventing plate structure schematic diagram;
Wherein, 1, hitch, 2, connecting pin, 3, couple yoke, 4, slip-off preventing plate, 5, bolt.
Detailed description of the invention
As depicted in figs. 1 and 2, big swing angle hitch anti-drop device, comprise hitch, couple yoke, connecting pin, hitch and couple yoke are flexibly connected by connecting pin, the downside of the corresponding connecting pin of couple yoke is bolted one block of slip-off preventing plate, and there is a groove position of the corresponding connecting pin of slip-off preventing plate, and connecting pin is that circular pin cap and rectangle shank are formed, pin-and-hole corresponding on couple yoke coordinates with rectangle shank, and the horizontal surface cross-sectional diameter of pin cap is greater than the catercorner length of shank horizontal surface cross-sectional plane.The groove of slip-off preventing plate is the rectangular recess that a level cross-sectionn size is identical with shank horizontal surface cross-sectional plane, has a through hole below groove.Rectangle shank is adopted can effectively to prevent hitch from swinging in normal driving process, pin cap is larger, can ensure landing can not occur at shank, and can not be thrown out of at operational process, through hole can be discharged into during groove from below there being fluid drips to reveal, make in connecting pin fracture, groove has withstood the connecting pin of breaking portion, ensures the operation of safety.
Claims (2)
1. big swing angle hitch anti-drop device, comprise hitch, couple yoke, connecting pin, hitch and couple yoke are flexibly connected by connecting pin, it is characterized in that: the downside of the corresponding connecting pin of couple yoke is bolted one block of slip-off preventing plate, there is a groove position of the corresponding connecting pin of slip-off preventing plate, connecting pin is that circular pin cap and rectangle shank are formed, and the pin-and-hole that couple yoke is corresponding coordinates with rectangle shank, and the horizontal surface cross-sectional diameter of pin cap is greater than the catercorner length of shank horizontal surface cross-sectional plane.
2. big swing angle hitch anti-drop device according to claim 1 is characterized in that: the groove of slip-off preventing plate is the rectangular recess that a level cross-sectionn size is identical with shank horizontal surface cross-sectional plane, has a through hole below groove.
